Grinding wheel dressing mechanism

The technical field of the invention and the dressing wheel of the grinding machine, more specifically, refers to a grinding wheel dressing mechanism of a grinding machine.

According to the current grinding process, which is called the grinding machine (grinding machine), the grinding machine is the first in the machining process. The sharpening of the cutting tool and the precise manufacture of the mechanical parts depend on the grinding. Work, grinding work is also part of precision machining. The role of the grinding machine is to perform highly precise and rough grinding with relatively small grinding, enabling high-efficiency grinding.

High-speed wheel grinding is the most common grinding operation in grinding work, mainly using grinding wheels. For the grinding of grinding wheels, the grinding wheel dresser is still used to achieve the accuracy of the workpiece.

The wheel dresser is a necessary wheel dressing tool for the conventional grinding machine. Due to the limitation of its own structure, the traditional wheel dresser can only adjust the distance between the grinding wheel and the dressing head through the visual mode of the operator, so that the dressing head touches. Touching the circumference of the grinding wheel to achieve the dressing effect, the fast and large feed dressing mode can not be operated during the dressing process, so that the operation mode not only makes the dressing precision low, the dressing efficiency is low, and the large amount of feed is easy to make the grinding wheel At high speed, the friction between the grinding wheel and the dressing head can not be loaded, and the grinding wheel is cracked or broken, and even the grinding head can be driven by the force at high speed, so that the grinding wheel and the trimming head break out and fly to the user. Many troubles are caused by unsafe operations.

In view of the shortcomings derived from the above-mentioned conventional wheel dresser, the creator of this case succeeded in researching and developing the grinding wheel dressing mechanism of this grinding machine.

The purpose of the present invention is to provide a grinding wheel mechanism for a grinding machine. In order to improve the prior art, the grinding wheel dresser of the conventional grinding machine has a tendency to cause a trimming head due to excessive feed amount, causing the dresser to hit the grinding wheel and causing the grinding wheel to rupture, and the grinding wheel fragments The problem of flying with the dresser is a safety hazard for the user.

The positioning device is internally provided with a positioning mechanism and a ratchet seat. The positioning mechanism is formed by a long rod. The upper end of the long rod is provided with a trimming head and a reference line, and the lower end is provided with the positioning mechanism and an elastic member. The compression function of the elastic member enables the trimming head to touch the grinding wheel, and has an elastic compression function, so that the contact force absorbs the compression function, and then the positioning mechanism engages the ratchet seat to achieve positioning. The effect is that the reference line under the trimming head reaches the preset position, so that the operator can recognize that the internal structure of the dresser has reached the preset compression value, and then the micro-feeding wheel contacts the dressing head in this step, and the passivated grinding wheel is trimmed. When the use is completed, the positioning mechanism can be separated from the ratchet seat by dialing a lever, thereby achieving the return to the original use state and achieving the above creation. The purpose of the grinding machine for the grinding wheel mechanism.

A positioning shaft 25 is disposed at the center of the upper end circumference. The positioning shaft of the positioning shaft 25 is disposed with an elastic member 26, and one end of the elastic member 26 abuts against the bottom end of the inner end of the seat body 22.

a ratchet seat 31, a handle 32 is disposed at an upper end of the ratchet seat 31, and the ratchet seat 31 has a plurality of rows of ratchet teeth 34 at one end side thereof, and the ratchet seat 31 is disposed at a distance from one of the plurality of rows of ratchet teeth 34 a groove 33 is disposed at a thickness of one end of the plurality of rows of ratchet teeth 34. A hole below the ratchet seat 31 is disposed through the positioning shaft 25, and the ratchet seat 31 is disposed on the pivot seat Between 24, the other end of the elastic member 26 abuts against the recess 33, and the elastic member 26 is elastically actuated to enable the ratchet seat 31 to return.

Referring to FIG. 2, the grinding wheel dressing mechanism of the grinding machine provided by the present invention comprises a sharpening device 1 comprising a long rod 12, a trimming head 11, a reference line 13, an elastic member 14 and a The positioning mechanism 4 has a long column shape, and the trimming head 11 is screwed on the upper end of the long rod 12, and the trimming head 11 can adjust the appropriate grinding angle to adjust the grinding wheel 51 by screwing relationship, and is convenient. The dressing head 11 of the different specifications is disassembled, and the reference line 13 is disposed under the trimming head 11. The positioning mechanism 4 is disposed under the reference line 13. An elastic member 14 is disposed under the positioning mechanism 4, and the upper end of the elastic member 14 is abutted. Topped to the positioning mechanism 4 The lower end surface, the lower end of the elastic member 14 abuts against the ring groove 27, and the positioning mechanism 4 is moved downward inside the seat 22 by the spring compression function, and the ratchet seat 31 is positioned.

Referring to FIG. 3 , the positioning mechanism 4 includes a bolt 42 , an elastic member 43 and a resisting member 44 . The side of the positioning mechanism 4 is provided with a screw hole 41 , and one end of the screw hole 41 is provided with a bearing surface 45 . The surface of the flange 45 is provided with a hole, and the end of the bolt 42 is provided with a recess. The elastic member 43 is disposed in the recess.

When the ratchet teeth 34 are touched At the time of the portion, the resisting member 44 is compressed by the elastic member 43 inside the bolt 42 to compress the arcuate head portion of the resisting member 44 inwardly, whereby the action can be moved downward according to different regular shapes, when the elastic member 14 is compressed. When the limit is reached, the reference line 13 is visually parallel to the top end surface of the cover 21 by the upper end surface of the cover 21, so that the operator recognizes the action of the mechanism to know that the dressing head 11 of the dresser has reached the limit of compression of the elastic member 14 to the limit. With this distance, the grinding wheel 51 can be fed a small distance in the direction of the dresser, and the periphery of the grinding wheel 51 can be trimmed and refined by the Y-axis of the bed, thereby achieving the passivation of the dressing wheel 51.

Referring to FIG. 5, when the wheel dresser is used, the lever 32 of the ratchet seat 31 can be directly pushed, and the elastic member 26 touches the inner bottom surface of the seat body 22 and one end surface of the recess 33 to generate elasticity. The compression action of the piece 26 causes the ratchet teeth 34 of the ratchet seat 31 to disengage from the arcuate head of the abutment member 44, allowing the dressing mechanism to return to its original use state.

Referring to FIG. 6 , in another preferred embodiment of the grinding wheel dressing mechanism of the present invention, the resisting member 44 can be replaced with another elastic piece 61. The elastic piece 61 is attached to the upper end surface of the positioning mechanism 4, and the elastic piece 61 is The abutting member 44 of the positioning mechanism 4 has the same function, and the one end convex portion of the elastic piece 61 is engaged with the plurality of rows of ratchet teeth 34, and can be elasticized by the elastic piece 61. Moving downwardly between the plurality of rows of ratchet teeth 34 and engaging the positioning, the lever 32 of the ratchet seat 31 is pushed to disengage the spring 61 from the engaging ratchet 34, allowing the dressing mechanism to return to its original use state.
