Description

The field of technology to which the utility model relates

The utility model relates to devices adapted for processing special products, namely to devices for processing the support flange of a sleeve in an engine block.

State of the art

The prior art discloses a DEVICE FOR PROCESSING A SEALING GROOVE ON AN ENGINE CYLINDER BLOCK, comprising a housing that can be secured to the surface of the engine block. The device has a rotating handle that projects laterally. The device is also equipped with a cutter for processing the sealing groove when the handle rotates. The device is designed in such a way that when the handle rotates, the cutter changes its height relative to the housing and, accordingly, the engine block, due to which it is fed to the surface of the sealing groove on the engine cylinder block. [US4876931A, published 10/31/1989].

The disadvantage of the analogue is the high labor costs when processing the bearing flange of the liner in the engine block, due to the impossibility of visual control and assessment of the need for additional processing of the liner flange, as a result of which it is necessary to install and remove the device from the engine block several times, the complexity of fixing the device, as well as the lack of the possibility of radial feed of the cutter, which leads to a significant increase in the contact area of the cutter and the surface being processed, due to which the load on the cutter and the minimum required force for rotating the handle increase, in addition, irregularities are formed on the surface being processed due to vibrations of the cutter.

Also known is the FAC86 CYLINDER BLOCK SLEEVE WORKING MACHINE, consisting of a vertical feed handle, a vernier graduation setting point, a locking screw for vertical feed, a vernier, an electromagnetic base, a quick tool adjustment, a tool movement lock, a crank handle for turning the spindle, a magnetization switch, a place for holding the equipment, a place for adjusting the tool, a cutting tool and a spindle cover [https://rpcpro.ru/remont-blokov-cilindrov/fac-86.html?ysclid=m7kfdpcwlw87980026].

The prototype of the utility model is the MACHINE FOR PROCESSING SLEEVE SEATS IN THE CYLINDER BLOCK MIRA BB86, consisting of an axial feed clutch, a micrometer screw, a locking screw, a scale, an electromagnet, a bracket, a toothed sleeve, a clamping screw, a handle for rotation, a switch, a handle, a cable, a boring tool (cutter), a main spindle, a nameplate indicating the serial number, a closing part and a centering roller [https://motortehn.com/zakaz-oborudovaniya/remont-blokov-cilindrov/mira-bb86/?ysclid=m7kfcyefpy900357620].

A common disadvantage of analogs is the high labor costs when processing the bearing flange of the liner in the engine block, due to the complexity of visual control of the processing of the seat in the cylinder block due to the need to bring and hold an additional light source when processing the bearing flange, as well as the need to disassemble and remove adjacent cylinder heads and liners and other parts protruding above the surface of the block, for example, the front and rear covers, which is due to the fact that the base is made of a round shape.

Implementation of a utility model

A device for processing a bearing flange of a sleeve in an engine block includes a base 1, to the lower part of which an electromagnet 2 is mounted by a permanent connection, and on the upper part a button 3 for controlling the electromagnet 2 is installed, in the central part of the base 1 a spindle housing 4 is mounted by a permanent connection, a limb 5 is installed on the upper part of the spindle housing 4, with the possibility of fixing it using a lock 6, above which a housing of support bearings 7 is located with support bearings inside, wherein, a spindle 8 is installed in the spindle housing 4, to the lower part of which a double-sided head 9 is mounted by a detachable connection, containing a holder 10 and a bar 11, holding and fixing a locking roller holder 12 with a centering roller 13 on one side and a cutter 14 with a hard-alloy insert 15 mounted by a detachable connection on the other side, wherein, through the central part of the double-sided head 9 a wedge is installed 16. In this case, a stud 17 is mounted to the upper part of the wedge 16 with a permanent connection, screwed with the opposite side into the radial feed nut 18, and a drive sleeve 19 is connected to the upper part of the radial feed nut 18, to the upper part of which a handle 20 is attached, the wedge 16 is designed with the possibility of converting and transmitting rotational motion into translational motion from the radial feed nut 18 to the cutter 14 and the roller holder 12, the base 1 is made in an H-shape, and a light source 21 is mounted in the lower part of the base 1.

In this case, the retainer 6 can be made in the form of a fixing screw.

In this case, the light source 21 can be designed with the possibility of switching on the electromagnet 2 with the control button 3 simultaneously with switching on the electromagnet 2.

The light source 21 specified in this description may be any device intended for converting electrical energy into light radiation sufficient to illuminate the support flange and fitting into the base 1, for example: LEDs, fluorescent lamps, halogen lamps, incandescent lamps, and so on.

The permanent connections specified in this description may be any method known from the prior art that ensures a reliable connection of parts, the subsequent separation of which violates the integrity of the components. For example, the connection may be made by welding or press fitting.

The detachable connections specified in this description may be any method known from the prior art that ensures reliable connection of parts, the subsequent disconnection of which does not violate the integrity of the components. For example, the connection may be carried out by means of bolts, studs, screws, screws, pins, etc.

According to this utility model, base 1 is necessary for installing the device perpendicular to the surface of the engine block, which ensures radial movement of cutter 14 in a plane parallel to the plane of the surface of the engine block, which ensures even formation of a sleeve flange of the same depth along the entire circumference.

In this case, base 1 is made in an H-shape, which makes it possible to work in hard-to-reach places and process the support flange without the need to dismantle adjacent cylinder heads, liners, rear engine cover, front engine cover, etc., which significantly simplifies the task and allows for a significant reduction in labor costs for processing the support flange of the liner in the engine block.

Also, according to this utility model, an electromagnet 2 is mounted to the lower part of the base 1, which is necessary for fixing and reducing the likelihood of displacement of the device for processing the support flange of the liner in the engine block after its installation, while the electromagnet 2 fixes the device by pressing the button 3 of the control of the electromagnet 2 once, which is one of the simplest and fastest ways of fixing and removing the device and allows to reduce labor costs for processing the support flange of the liner in the engine block by simplifying the fixation and removal of the device.

In addition, a light source 21 is mounted in the lower part of the base 1, which is necessary for providing visual control over the process of processing the support flange, which allows for continuous evaluation of the quality of processing and the need for additional processing of the support flange, wherein the light source 21 can be configured to be switched on by button 3 for switching on the electromagnet 2 simultaneously with switching on the electromagnet 2, which ensures a constant supply of light during fixation and operation of the device, thereby eliminating the need to install additional light or the need to remove the device each time during a visual analysis of the quality of processing of the support flange of the liner in the engine block, and therefore reduces the operating time and reduces labor costs during visual analysis and quality control of processing of the support flange of the liner in the engine block.

The spindle body 4 is necessary for installing and fixing the spindle 8, preventing the spindle 8 from making arbitrary longitudinal movements, which ensures the possibility of radial feed of the cutter 14 and cutting the flange of the sleeve in the engine block in one plane at the required depth of the sleeve.

Spindle 8 is necessary for mounting on its lower part a two-sided head 9, wherein spindle 8 is designed with the possibility of both rotational movement and translational movement. Rotational movement is transmitted to spindle 8 from handle 20 using drive sleeve 19 and is necessary for rotating two-sided head 9, roller holder 12 and cutter 14. Translational movement of spindle 8 is adjusted using limb 5 and is necessary for adjusting the feed height of cutter 14, which allows processing the liner flange in the engine block at the required liner depth.

Limb 5 allows you to adjust the degree of extension of spindle 8, thereby changing the feed height of the cutter relative to the surface of the engine block, which ensures cutting the flange of the sleeve at the required depth of the sleeve.

The lock 6 allows the limb 5 to be fixed, which reduces the probability of arbitrary rotation of the limb 5 and ensures radial feed of the cutter 14 and cutting of the sleeve flange in the engine block in one plane at the required sleeve depth.

In this case, the retainer 6 can be made in the form of a fixing screw, which ensures simple and quick fixation of the limb 5.

In combination, the limb 5, the lock 6 and the spindle 8 allow adjusting the feed height of the cutter 14 and holding the cutter 14 in one plane at a given height, which allows controlling the depth of processing the liner flange and the thickness of the metal layer being removed, while making the liner flange parallel to the plane of the engine block surface, and also changing the depth of processing the support flange if necessary, without removing or disassembling the device for processing the liner support flange in the engine block, which also allows saving time and reducing labor costs when processing the liner support flange in the engine block.

The support bearing housing 7 is necessary for installing support bearings, which are necessary in turn to ensure smooth rotational movement of the handle 20, drive sleeve 19, radial feed nut 18, stud 17, wedge 16, double-sided head 9 and spindle 8 relative to the base 1, spindle housing 4 and limb 5. Support bearings, in turn, are one of the optimal solutions for ensuring controlled rotational movement of elements, since they have a minimum coefficient of friction during rotation during operation of the device, and therefore require minimal application of force when rotating the handle 20, and therefore reduce labor costs when working with the device.

The two-sided head 9 is necessary for placing the holder 10 in it and for ensuring the possibility of the holder 10 performing a longitudinal movement when changing the position of the wedge 16. In this case, the holder 10 is necessary for holding and fixing, using the retaining bar 11, the holder of the roller 12 with the centering roller 13 and the cutter 14 with the hard-alloy insert 15, which together ensures the possibility of radial feed of the holder of the roller 12 with the centering roller 13 and the cutter 14 with the hard-alloy insert 15, necessary for processing the bearing flange of the sleeve in the engine block. Also, this design of the double-sided head 9 allows for quick and easy replacement of the cutter 14 or the roller holder 12, for which it is necessary to simply loosen the retaining bar 11, fixed, for example, by means of a threaded connection, remove the cutter 14 or the roller holder 12, install a new one and tighten the retaining bar 11 again, which simplifies the replacement of the cutter 14 or the centering roller 13 if necessary, therefore, reducing labor costs when working with the device.

The stud 17 is an element connecting the radial feed nut 18 and the wedge 16, wherein one end of the stud 17 is mounted with a permanent connection to the wedge 16, and the second end is screwed into the radial feed nut 18. Thus, when the radial feed nut 18 rotates, the stud transmits a forward or backward translational motion to the wedge. In this case, the wedge 16 is made in such a way that during translational motion it passes through the double-sided head and transmits translational motion to another plane, thereby moving the holder 10 together with the roller holder 12 and the cutter 14.

Thus, when the radial feed nut 18 rotates relative to the wedge 16, the rotational motion is converted into translational motion, moves into a perpendicular plane and is transmitted to the holder 10, thereby longitudinally moving the roller holder 12 and the cutter 14, which makes it possible to provide radial feed of the cutter 14 and the centering roller 13 without any additional labor costs.

The roller holder 12 is necessary for fixing the centering roller 13, ensuring the possibility of rotation of the centering roller 13. The centering roller 13 is necessary for centering the device relative to the sleeve by radially feeding the centering roller 13 until the base 1 remains static relative to the engine block when the centering roller 13 has completely passed the circle, which is an accurate, simple and least labor-intensive method of centering the device, and therefore reduces labor costs when working with it.

Cutter 14 is required for machining the bearing flange of the liner by removing the uneven surface of the bearing flange. In this case, the radial feed of cutter 14 ensures a minimum point of interaction of the hard-alloy insert 15 with the surface of the bearing flange, which reduces the likelihood of unevenness during machining of the surface of the bearing flange, allows machining the surface of the bearing flange with less effort, and also increases the accuracy of machining the bearing flange of the liner in the engine block.

The hard alloy insert 15 is installed at the end of the cutter and is an element that directly contacts the support collar. The hard alloy insert 15 is necessary for processing the surface of the support collar, while the hard alloy insert 15 is more wear-resistant and easily processes the surface of the support collar due to the sharpness and high hardness of the material.

Thus, the radial feed of the cutter 14 and the hard insert 15 at the end allow the support shoulder to be processed by applying a minimum amount of effort to rotate the handle 20.

The handle 20 is necessary for manual provision of rotational movement to the movable elements of the device, the drive sleeve 19, in turn, is a connecting element of the handle 20 with the other elements and transmits rotational movement. Thus, the handle 20 and the drive sleeve 19 provide operation of the device for processing the bearing flange of the liner in the engine block. Moreover, the handle 20 is designed in such a way that it describes a circle with a radius greater than the radius of the circle formed by the rotation of the cutter 14, which allows working with the help of this device, applying significantly less force to the handle 20, and therefore reduces labor costs when processing the liner flange in the engine block.

Thus, the H-shaped base 1, the light source 21 configured to be switched on by the electromagnet control button simultaneously with switching on the electromagnet 2, the electromagnet 2, the button 3, the spindle housing 4, the limb 5, the lock 6, the housing of the support bearings 7, the support bearings, the spindle 8, the double-sided head 9, the holder 10, the bar 11, the roller holder 12, the centering roller 13, the cutter 14, the carbide insert 15, the wedge 16 configured to convert and transmit rotational motion into reciprocating motion from the radial feed nut 18 to the cutter 14 and the roller holder 12, the pin 17, the radial feed nut 18, the drive sleeve 19 and the handle 20 together reduce the labor costs when processing the sleeve flange in the engine block due to:

- eliminating the need to dismantle adjacent cylinder heads, cylinder liners, rear engine cover, front engine cover, etc.;

- eliminating the need to install external lighting;

- simple and quick installation, centering, fixing and removal of the device;

- the ability to adjust the feed height of the cutter 14;

- simple and quick replacement of cutter 14 and centering roller 13;

- reducing the forces applied to the handle 20 to rotate the cutter 14.

Protocol for conducting comparative tests

To determine the objective manifestation of the technical result, comparative tests were conducted, in which the device proposed in this patent was compared with the closest and most popular analogue:

Device No. 1 - a device for processing the bearing flange of a sleeve in an engine block, proposed by this patent;

Device No. 2 - machine for processing cylinder liner seats in the MIRA BB86 cylinder block.

Several different engine models of the most popular brands were used for testing. The time spent on work and key differences when working with the devices were displayed in Table 1.

Table 1 - Key differences

Engine and cylinder number Working time spent working with device No. 1 Working time spent working with device No. 2 Comments MAN D28,
2 cyl. 3 hours 6 hours When working with device #2, it was necessary to dismantle and then re-mount two adjacent cylinder heads (CHB), as well as two adjacent liners due to the round shape of the base, which took an additional 3 hours of work time and also led to additional consumption of gaskets and seals. The H-shaped base of device #1 allowed the device to be installed on the surface of the engine block without additional dismantling of the CBC and liners. VOIVO D12,
1 cyl. 3 hours 11 o'clock When working with device #2, it was necessary to dismantle and then re-mount the cylinder head and the sleeve of the second cylinder, and it was also necessary to dismantle and mount the front engine cover, since its protruding part did not allow installing device #2. The H-shaped base of device #1 allowed installing the device and processing the support flange without dismantling the above-mentioned elements. YaMZ 534, 6 cyl. 3 hours 15 hours When working with device #2, it was necessary to dismantle and then re-mount the cylinder head and sleeve of the fifth cylinder, as well as the rear engine cover, which required dismantling and partial disassembly of the entire engine. The H-shaped base of device #1 allowed the device to be installed and the support flange to be processed without dismantling the fifth cylinder and the entire engine.

Thus, it can be seen that the main labor costs when processing the bearing flange of the liner in the engine block are precisely due to dismantling and assembly work, most of which device No. 1 allows to avoid, thereby significantly reducing labor costs and working time for the work. In addition, in all three cases, the convenience of the built-in lighting and the simpler and more reliable radial feed of the cutter 14 were noted, which also made the work easier.
