Description

Technical Field

[0001] The invention relates to the technical field of drilling and milling equipment, in particular to a drilling and milling equipment for a silencer pad of an automobile brake pad. Background Art

[0002] When the brake pad is assembled to the brake, it moves up and down with the brake during braking. The bottom of the brake pad collides with the brake base, which will produce abnormal noise. The silencer pad plays a role in eliminating abnormal noise after the brake pad is installed in the brake. The size control of the silencer pad will affect the silencer effect after assembly. If two silencer pads are installed on a brake pad, when the height difference between the two silencer pads is large, it will cause the brake pad to shift, the piston to not be pushed into place, and uneven wear. The existing method of ensuring the size is to manually place a limit block of standard thickness and then use an auxiliary cutting tool to cut off the excess size. This method has low precision and low efficiency, not only wasting time, but also increasing labor intensity, and failing to meet the size requirements of the silencer pad. Summary of the Invention

[0003] In view of this, the present invention provides a drilling and milling device for automobile brake pad silencer pads, which can realize automatic and precise processing of silencer pads through automated drilling and milling equipment, without the need for manual cutting of excess dimensions.

The present invention can adjust the distance between the fixing mechanism and the cutting mechanism through a moving mechanism, and drive the power head connected to it to rotate together through the rotation of the output shaft of the driving motor. The rotation of the power head drives the tool handle and the tool to rotate, and then the fixing mechanism that fixes the silencer pad body is manually pushed to move along the guide mechanism, thereby realizing the cutting operation of the protruding part of the silencer pad body. The present invention realizes automatic and precise processing of the silencer pad through automated drilling and milling equipment, and does not require manual cutting of excess size. While improving processing accuracy, it also improves processing efficiency and greatly reduces labor intensity.

[0005] The output shaft end of the driving motor and the end of the power head are both provided with a synchronous pulley, and the two synchronous pulleys are located on the same vertical line. A transmission belt is provided between the two synchronous pulleys, and the other side end of the power head is connected to the tool handle by a key and a keyway. The rotation of the output shaft of the driving motor can drive the synchronous pulley connected to it to rotate, and the rotation of the synchronous pulley will drive the synchronous pulley at the end of the power head to rotate together, and then drive the power head to rotate accordingly. The rotation of the power head will drive the tool handle and the tool to rotate, thereby realizing the cutting operation of the protruding part of the silencer pad body within the cutting range of the tool, which is more convenient and efficient, does not require manual cutting, has higher cutting efficiency, and is more accurate in size.

[0006] The moving mechanism includes a linear slide arranged on a base, a slide is arranged on the upper part of the slider of the linear slide, and guide rails are arranged on the lower part of the slide and on both sides of the linear slide, and a guide block is slidingly arranged on the guide rail, and the upper part of the guide block is fixed together with the lower part of the slide, and the screw can be rotated by rotating the output shaft of the motor of the linear slide. Due to the threaded connection between the screw and the slider of the linear slide, the rotation of the screw will drive the slider of the linear slide to move along the slide rail of the linear slide, thereby realizing the adjustment of the distance between the fixing mechanism and the cutting mechanism on the upper part of the slide, which is convenient for adapting to the cutting processing of silencer pad bodies of different specifications and thicknesses, is more convenient and has stronger applicability. The cooperation of the guide block and the guide rail can make the sliding of the slide along the linear slide and the guide rail more stable.

[0007] The fixing mechanism includes a workpiece for placing the silencer pad body, and a fixing groove for fixing the silencer pad body is opened on the workpiece. The fixing groove is adapted to the shape of the silencer pad body, and the silencer pad body is inserted into the fixing groove. The silencer pad body can be fixed through the fixing groove, and there is no need for people to manually hold the silencer pad body for cutting, so the cutting efficiency is higher and the cutting accuracy is more precise.

[0008] The guide mechanism includes a limit block arranged on the upper part of the slide and close to the side of the tool. The limit block is detachably arranged on the upper part of the slide by a bolt. A limit groove for the tool to pass through is provided on the limit block. The movement of the silencer pad body fixed on the workpiece can be guided and limited by the guiding action of the guide mechanism. A person manually pushes the fixed silencer pad body to be cut to move along the limit block, and then cooperates with the high-speed rotating tool to cut the raised part of the silencer pad body, thereby achieving more efficient and accurate precision processing of the silencer pad body. There are two limit grooves, which are located on the front and rear sides of the vertical part of the limit plate on the side close to the tool. The size and position of the tool avoidance groove and the limit groove correspond one to one, and are adapted to the position of the tool avoidance groove. Through the joint action of the limit groove and the tool avoidance groove, not only can the influence of interference in the tool cutting process on the processing be avoided, but also the waste of the cut silencer pad body can be guided to fall, and it can be avoided that it accumulates on the limit plate, which is more convenient.

[0009] A knife avoidance groove is provided on the outer side wall of the vertical part of the slide plate on the side close to the tool for avoiding the cutting operation of the tool. There are two knife avoidance grooves, which are respectively located on the front and rear sides of the vertical part of the slide plate on the side close to the tool. The knife avoidance groove is used to provide avoidance space for the rotating cutting of the tool, and facilitates the automatic falling of the waste material of the cut silencer pad body to avoid its accumulation on the slide plate affecting the subsequent cutting operation of the silencer pad body.

[0010] There are two cutting mechanisms, and a plurality of adjustment holes for adjusting the distance between the two cutting mechanisms are provided on the base. The adjustment holes facilitate adjustment of the distance between the two cutting mechanisms, and facilitate processing operations on different types of silencer pad bodies, with a wider range of applications and greater intelligence and convenience.

[0011] The utility model also includes a mounting mechanism for pressing the silencer pad body into the corresponding mounting hole of the workpiece, the mounting mechanism includes an adjusting component which is arranged on the outside of the slide and is located on the base with adjustable spacing, the adjusting component is provided with a pushing component for pushing the silencer pad body into the corresponding mounting hole on the workpiece, the adjusting component includes an adjusting rail arranged on the base, a mounting plate is slidably provided on the adjusting rail, an adjusting slot which is adapted to the adjusting rail is opened on the back of the mounting plate, a fixing plate is provided on the fixing plate, a telescopic push rod is provided on the fixing plate, a material discharge seat is provided on the axis of the output rod of the telescopic push rod, the telescopic push rod is an electric telescopic rod or a hydraulic telescopic rod, and when it is needed When pressing the silencer pad body into the corresponding mounting hole in the workpiece, first adjust the adjustment slot on the mounting plate according to the position of the mounting hole on the workpiece and slide it along the adjustment track until it coincides with the axis of the mounting hole, then lock the position of the mounting plate, and then place the silencer pad body into the positioning hole on the discharge seat, and then start the output rod of the telescopic push rod to extend it to press the silencer pad body into the corresponding mounting hole on the workpiece, and then manually grasp the workpiece and rotate it 180 degrees to make the side of the workpiece where the silencer pad body to be processed is installed to conflict with the vertical side wall of the limit plate, and then start the cutting mechanism while manually pushing the workpiece along the limit plate to realize the cutting operation of the silencer pad body.

[0012] There are four legs at the bottom of the base, which are evenly distributed on the four corners of the base to support and fix the drilling and milling equipment.

[0013] In summary, compared with the prior art, this application has at least one of the following beneficial technical effects:

[0014] 1. Most existing methods for ensuring the processing size of the silencer pads are to manually place limit blocks of standard thickness and then use auxiliary cutting tools to cut off the excess size. This method has low precision and low efficiency, which not only wastes time but also increases labor intensity and cannot meet the size requirements of the silencer pads.

[0015] The present invention realizes automatic and precise processing of the sound-absorbing pad through the automated drilling and milling equipment, does not require manual cutting of excess size, improves processing accuracy, improves processing efficiency, and greatly reduces labor intensity.

[0016] 2. Since two silencer pads are installed on a brake pad, when the height difference between the two silencer pads is large, it will cause the brake pad to deviate, the piston to not be pushed into place, and uneven wear. The present invention sets two cutting mechanisms to work synchronously, and correspondingly opens two fixed grooves on the workpiece that are compatible with the cutting range of the tool, so that the two silencer pad bodies can be processed at the same time. In this way, the large height deviation of the two silencer pads caused by separate cutting can be avoided to a great extent, and the processing accuracy of the two silencer pads can be ensured, thereby ensuring the accuracy of the brake pad assembly position and avoiding the occurrence of problems such as the piston not being pushed into place and uneven wear.

[0017] 3. The present invention can adjust the distance between the two cutting mechanisms through the adjustment hole on the base, and cooperate with the slider of the linear slide to drive the slide plate and the fixing mechanism to move along the slide rail of the linear slide, thereby adjusting the distance between the tool and the fixing mechanism, which is convenient for cutting the silencer pad body with different processing sizes and different processing distances. It can be used for processing silencer pads of various different models, and the functions are more diversified.

[0018] 4. The guiding function of the guide mechanism can guide and limit the movement of the silencer pad body fixed on the workpiece. People manually push the fixed silencer pad body to be cut along the limit block, and then cooperate with the high-speed rotating tool to cut the raised part of the silencer pad body, so that the precise processing of the silencer pad body is achieved more efficiently and accurately.

[0019] 5. A knife avoidance groove is provided on the outer wall of the vertical portion of the slide plate on the side close to the tool to avoid the cutting operation of the tool. The knife avoidance groove is used to provide an avoidance space for the rotary cutting of the tool and facilitates the automatic falling of the waste material of the cut silencer pad body, thereby avoiding its accumulation on the slide plate and affecting the subsequent cutting operation of the silencer pad body.

[0020] 6. The installation mechanism can realize the accurate and fast installation of the silencer pad body, without the need for manual tools to hammer the silencer pad body into the corresponding installation hole of the workpiece, effectively avoiding the damage to the silencer pad body due to the impact force of the tool or the uncertainty of manpower or the improper installation of the silencer pad body, which will cause the processing scrap rate of the silencer pad body, and is more convenient and efficient.
