Definitions
- the invention relates to a device for machining the bearing half-shells of plain bearings with a clamping device for the feed and discharge via conveyor devices bearing half-shells and with a movable via a feed drive tool carriage, which is connected to a spindle drive, preferably a tool spindle with two in one axially spaced from each other cutting tools in a spindle housing pivotally adjustable about an axis, which is perpendicular to the axial plane of symmetry of the half-shells clamped in the clamping device.
- the bearing half-shells do not have to be drilled eccentrically in two successive machining steps, first according to the nominal diameter of the tread and then with a slightly larger diameter, in order to achieve a corresponding exemption of the shaft to be supported in the axial joint area between the two bearing half-shells of a plain bearing the drilling spindle is not aligned coaxially to the axis of the bearing half-shells, but pivoted about an axis that is perpendicular to the plane of symmetry of the bearing half-shells.
- This inclination of the drill spindle axis relative to the axis of the bearing half-shell results in a radial offset with an axial displacement of two drill bits for these drill bits with respect to the axis of the bearing half-shells, so that with a corresponding choice of diameter of the cutting circles of the drill bits, the two mutually radially offset bores with different diameters can be done in one operation. Since the feed movement must run in the direction of the axis of the bearing half-shells in spite of the inclination of the drill spindle, the spindle housing for the inclination adjustment of the drill spindle must be pivoted in a slide which is connected to a feed drive.
- the invention is therefore based on the object of designing a device for machining the bearing half-shells of slide bearings of the type described in such a way that the cycle times for the automatic machining of the slide bearing shells can be significantly reduced while maintaining the tool spindle inclined with respect to the bearing half-shell axis ,
- the invention solves this problem in that the spindle housing accommodates two coaxial, opposite sides, driven by the common spindle drive, alternately usable tool spindles, that the spindle housing connected to feed and discharge conveyors are arranged upstream and downstream for the bearing half-shells and that the spindle housing in Depending on the use of the two tool spindles, it can be swiveled back and forth to a limited extent using a swivel drive.
- the alternating machining of the bearing half-shells on the two slide sides allows the use of a common spindle drive for the two tool spindles without having to increase the drive power.
- Particularly simple constructional relationships result with regard to the spindle drive if the two tool spindles are combined to form a structural unit which forms the rotor of a spindle motor.
- the supply and discharge of the bearing half-shells to and from the clamping devices can be done in different ways.
- the two clamping devices which are adjustable perpendicular to the tool slide feed and to the pivot axis of the spindle housing, can be assigned a common feed conveyor for the bearing half-shells, which can be moved back and forth between the clamping devices parallel to the tool slide.
- the other clamping device can be loaded with a bearing half-shell to be machined in one of the two clamping devices during the machining of a bearing half-shell.
- the clamping devices are to be moved between a loading position and a working position, which should take place perpendicular to the tool slide feed and the pivot axis of the spindle housing in view of a predetermined takeover position of the bearing half-shells.
- the bearing half-shells can also be advantageously taken over by the common feeder. This applies in particular if the common feed conveyor has two pairs of support arms, each protruding against a tensioning device, for receiving the bearing half-shells.
- the bearing half-shells resting on the pair of support arms with the tread to be machined can be inserted via the support arms into the preferably die-like receptacle of the tensioning device without difficulty and tensioned there for processing before the feed conveyor is moved back by the tensioning device, which is then shifted into the working position.
- This return movement corresponds to a forward movement of the oppositely aligned support arms of the feed conveyor, which reach under a prepared further bearing half-shell and can feed the opposite tensioning device.
- a finished half-shell can be ejected in the axial direction from the tensioning device onto a conveyor before the newly inserted half-shell is tensioned and shifted into the working position with the tensioning device.
- the swivel drive for the spindle housing can consist of swivel cylinders arranged on both sides of the swivel axis, with on each swivel axis side between adjustable spindle stops are provided for the spindle housing and the tool slide.
- the spindle housing is held in each case by a swivel cylinder on one swivel axis side against an adjustable swivel stop on the opposite swivel axis side, so that compliance with the specified swivel angle can be ensured with great accuracy.
- the swivel stops are designed to be adjustable, for example with the aid of a screw drive.
- FIG. 1 is a schematic side view of an inventive device for machining the bearing half-shells of plain bearings
- Fig. 2 shows this device in a partially broken plan view
- Fig. 3 shows a clamping device for the plain bearing half-shells in a partially torn, partial front view.
- the device for machining the bearing half-shells 1 has a frame 2 a tool carriage 3, which can be moved along its guides 4 with the aid of a feed drive 5, which consists, for example, of a spindle drive 6 which can be driven via a belt drive.
- a feed drive 5 which consists, for example, of a spindle drive 6 which can be driven via a belt drive.
- a spindle housing 7 is pivotally mounted, specifically about a horizontal pivot axis 8 perpendicular to the direction of advance of the slide 3.
- the spindle housing 7 accommodates two coaxial tool spindles 9, which indeed form a common shaft , but protrude from the spindle housing 7 on opposite sides.
- These tool spindles 9 are part of a rotor of the spindle drive designed as an electric motor 10.
- the spindle housing 7, which forms a structural unit with the spindle drive 10, is connected on both sides of the pivot axis 8 to a pivot cylinder 11 supported on the tool slide 3, so that when the Stelizylinder on one side of the swivel axis, the spindle housing 7 is pivoted to one side and when the other Stelizylinder 11 is loaded, to the other side.
- the swivel angle is determined by swivel stops 12, which can be adjusted via a screw drive.
- the tool spindles 9 carry two drill bits 13 and 14 at a mutual axial distance, of which the drill bit 13 closer to the free tool spindle end describes a smaller cutting circle than the drill bit 14.
- the device shown is equipped for fine boring of the bearing half-shells 1, grinding or milling tools could also be used instead of the drilling tools 13 and 14 in order to be able to machine the bearing half-shells 1 accordingly. If only one tool is provided on each tool spindle 9, the advantage of machining relating to two different diameters is dispensed with, but the advantages with regard to shortening the cycle time can be used in the same way.
- the frame 2 carries two the spindle housing 7 in the feed direction of the tool slide 3 upstream and downstream clamping devices 15 for one bearing half shell 1. These clamping devices 15 are arranged on slides 16, which are in vertical guides 17 perpendicular to the slide guide 4 and the pivot axis 8th can be shifted between an upper loading position and a lower working position via actuators 18.
- the clamping devices 15 form a die-like receptacle 19 for the bearing half-shells 1, which can be clamped in the receptacle 19 in a manner suitable for drilling via lateral clamping jaws 20.
- the machined half-shells 1 can be pushed out of the receptacle 19 in the axial direction when the clamping jaws 20 are open, the clamping jaws 20 forming a guide for the half-shells 1.
- a common feed conveyor 22 is provided between the two clamping devices 15, which is displaceable on the guides 4 of the tool slide 3 parallel guide rails 23 with the aid of a spindle drive 24 and a boom 25 with two against one Has clamping device 15 protruding pairs of support arms 26 for receiving the bearing half-shells 1.
- This feed conveyor 22 takes over the bearing half-shells 1 with their axial end faces on a conveyor table 27, in that the pair of support arms 26 protruding against the bearing half-shell 1 engages underneath the bearing half-shell 1 and conveys them in the axial direction into the receptacle 19 of the clamping device 15 assigned to this pair of support arms, in which the bearing half-shell 1 is tensioned in the manner described before the tensioning device 15 is lowered into the working position. In this working position, drilling is carried out via the two drill bits 13 and 14 with a spindle axis inclined with respect to the axis of the bearing half-shell 1.
- This inclination of the spindle axis in the plane of symmetry of the bearing half-shells 1 requires that the center 28 of the cutting circle 29 of the drill bit 13 lies on the axis of the clamped bearing half-shell 1, but not the center 30 of the cutting circle 31 of the drill bit 14, as shown in FIG. 3 can be removed.
- This means that the bearing half-shell 1 is drilled out with a larger diameter in the area of the axial abutment surfaces in order to ensure the desired release of the shaft to be supported in the abutment area between the bearing half-shells.
- the feed conveyor 22 is moved in opposite directions in order to receive another bearing half-shell 1 with the opposite pair of support arms 26 from the conveyor table 27 and to feed the opposite clamping device 15.
- a bearing half-shell 1 that has already been machined can be conveyed out in the axial direction from the clamping device 15 onto a subsequent removal conveyor 32.
- the clamping device 15 is lowered into the working position, so that the tool slide 3 which is reversed in its direction of movement is guided against the new bearing half-shell 1.
- the spindle housing 7 Before the drilling operation can be carried out, however, the spindle housing 7 must be pivoted in opposite directions so that the tool spindle 9 now used assumes the inclination position relative to the bearing half-shell 1 required for the drilling process.
- the cycle time can thus be considerably reduced, because during the use of one tool spindle 9 the unloading, loading and clamping of the clamping device 15 associated with the other tool spindle not in use can take place.
- the bearing half-shells 1 to be machined can be provided intermittently on the conveyor table 27, they are conveyed via a longitudinal conveyor 33 indicated in FIG. 2, from which they can be moved with a slider arm 34 onto the conveyor table 27 in a stop-limited manner.
- the height of the slide arm 34 is adjustable in a slide 35 which can be moved along a guide 36.
- the finished bearing half-shells 1 can be transferred to a common longitudinal conveyor 38 (FIG. 2) via slide arms 37.
- the slide arms 37 can be mounted in a corresponding structure, adjustable in height, in slides 39, which are moved along guides 40.
- the invention is of course not limited to the illustrated embodiment because, for example, it does not depend on the construction of the feed and discharge conveyor or the tensioning devices 15.
- the only decisive factor is that the two tool spindles 9 are used alternately in order to be able to prepare the machining of another bearing half-shell by the other tool spindle during the drilling operation of a bearing half-shell 1, so that the idle times otherwise caused by these preparations are eliminated.
