Description

Technical Field

[0001] This invention relates to the field of automotive brake pad processing technology, and in particular to a processing equipment for automotive brake pads. Background Technology

[0002] Car brake pads, also called car brake shoes, refer to brake pads that are fixed to the brake system. wheel On a rotating brake drum or brake disc friction Material The friction linings and friction blocks therein bear external pressure and generate friction to achieve the purpose of vehicle deceleration;

[0003] When processing brake pads, traditional equipment often uses mechanical clamping plates or unidirectional ejector pins, which can only fix the reference plane and cannot adapt to curved surfaces. This causes the workpiece to shift after clamping. Furthermore, centrifugal force during grinding causes vibration, resulting in edge chipping. After grinding, polishing requires multiple manual flipping, resulting in low overall processing efficiency of brake pads and poor processing consistency of brake pads in the same batch. In addition, the open sandblasting polishing method can easily cause abrasive splashes, affecting the overall environment of the processing site and even affecting the processing of subsequent brake pads.

[0004] Although the existing technology CN119141412B fixes the brake pads through positioning holes, its clamp is a rigid one-way locking structure, which cannot adapt to curved workpieces and lacks a closed automated design for the flipping and polishing process. In view of this, there may already be technical means to solve the above problems in the existing technology, but this case aims to provide an alternative or replacement technical solution. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems by designing a processing equipment for automotive brake pads. This equipment addresses the issues of existing brake pad processing methods, which often employ mechanical clamps or unidirectional ejector pins. These methods only fix the reference plane and cannot adapt to curved surfaces, leading to workpiece misalignment after clamping. Furthermore, centrifugal force during grinding causes vibration, resulting in edge chipping. Additionally, polishing after grinding requires multiple manual flipping operations, resulting in low overall processing efficiency and poor consistency within the same batch of brake pads.

[0032] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figure 1-9 As shown, a processing device for automotive brake pads.

[0033] Example: A processing equipment for automotive brake pads includes a base plate 1, a placement rack 2, a mounting groove 3, and two polishing boxes 4. The placement rack 2 is fixedly installed at the center of the upper end of the base plate 1, the mounting groove 3 is opened on one side of the upper end of the placement rack 2, the two polishing boxes 4 are respectively installed on both sides of the upper end of the base plate 1, the base plate 1 and the upper end of the placement rack 2 are equipped with positioning grinding structures, the upper rear side of the base plate 1 is equipped with a moving feeding structure, and the two polishing boxes 4 are equipped with two flipping polishing structures.

[0034] The positioning and grinding structure includes: a first cylinder 5, a mounting sleeve 6, two mounting plates 7, two fixing bolts 8, two fixing blocks 9, two guide blocks 10, two guide rods 11, two second cylinders 12, two positioning rods 13, two operating rods 14, two hinge seats 15, two operating holes 16, two positioning blocks 17, and grinding components.

[0035] The first cylinder 5 is fixedly installed at the rear side of the center of the upper end of the base plate 1. The mounting sleeve 6 is fixedly installed on the telescopic end of the first cylinder 5. Two mounting plates 7 are respectively movably embedded on both sides of the mounting sleeve 6. Two fixing bolts 8 are respectively movably embedded on both sides of the upper wall of the mounting sleeve 6. Two fixing blocks 9 are respectively installed on the front and rear walls of the mounting sleeve 6. Two guide blocks 10 are respectively installed on the outer walls of both sides of the first cylinder 5. The top ends of two guide rods 11 are respectively connected to the lower walls of the two fixing blocks 9, and the bottom ends are respectively movably embedded in the two guide blocks 10. The two second cylinders 12 are... The two mounting plates 7 are installed at the bottom, the two positioning rods 13 are installed at the top of the two mounting plates 7 respectively, the bottom of the two operating rods 14 are connected to the telescopic ends of the two second cylinders 12 respectively, and the top ends are movably embedded in the two positioning rods 13 respectively. The two hinge seats 15 are installed on the upper side walls of the two operating rods 14 respectively, the two operating holes 16 are opened on the upper side walls of the two positioning rods 13 respectively, one end of the two positioning blocks 17 is hinged to the two hinge seats 15 by torsion springs respectively, and the other end is movably inserted into the two operating holes 16 respectively. The grinding assembly is fixedly installed on the upper end of the placement frame 2.

[0036] When processing automotive brake pads, the operator first moves the device to a designated position, supports it with the base plate 1, and connects it to a designated control system. Then, the operator places the brake pads to be processed on the upper end of the placement rack 2, aligning the mounting groove 3 with the placement groove 49 to position them. The moving feeding structure then moves the brake pads above the first cylinder 5, driving the first cylinder 5 to push the mounting sleeve 6 and two mounting plates 7 upwards until the two positioning rods 13 are embedded in the through holes on both sides of the brake pads. Next, the two second cylinders 12 are driven, causing the two operating rods 14 to move downwards within the two positioning rods 13. When one end of the two positioning blocks 17 is within the two operating holes 16, under the reset action of the torsion spring, the two positioning blocks 17 rotate within the two hinge seats 15, causing one side of each positioning block 17 to penetrate the two operating holes 16. Finally, the first cylinder 5 is driven to retract, driving... The mounting sleeve 6 moves downward until the two positioning blocks 17 contact the upper surface of the brake pad backing plate, thus fixing the brake pad. The mounting sleeve 6, in conjunction with the two mounting plates 7, allows for adjustment of the spacing between the two mounting plates 7 according to different processing requirements. Finally, the spacing is fixed using the fixing bolts 8. This method is applicable to fixing brake pads of different specifications. The two guide rods 11 at the lower end of the two fixing blocks 9, in conjunction with the two guide blocks 10, ensure the overall lifting stability of the mounting sleeve 6. When it is necessary to release the brake pad, the first cylinder 5 and the second cylinder 12 work synchronously. The second cylinder 12 pushes the operating rod 14 upward, causing the upper surface of the positioning block 17 located in the operating hole 16 to contact the upper wall of the operating hole 16. Under the pressure, the positioning block 17 flips within the hinge seat 15, compressing the torsion spring. As the operating rod 14 moves upward, the positioning block 17 retracts into the positioning rod 13, thus releasing the brake pad from its fixing purpose.

[0037] In the specific implementation process, the grinding components include: grinding frame 18, third cylinder 19, cross slide 20, grinding motor 21 and grinding disc 22;

[0038] The grinding frame 18 is fixedly installed on the upper end of the placement frame 2, the third cylinder 19 is fixedly embedded in the center of the grinding frame 18, the cross slide 20 is fixedly installed at the telescopic end of the third cylinder 19, the grinding motor 21 is fixedly installed on the output end of the cross slide 20, and the grinding disc 22 is fixedly installed on the output end of the grinding motor 21.

[0039] After the brake pads are fixed, the third cylinder 19 at the upper end of the grinding frame 18 is driven to work, pushing the cross slide 20 and the grinding motor 21 to move downward. Then the grinding motor 21 is driven to work, and the grinding disc 22 rotates at high speed to contact the upper surface of the brake pads to perform grinding operations. The position of the grinding disc 22 can be adjusted by the cross slide 20 to ensure the grinding effect of the brake pads.

[0040] The cross slide 20 consists of two sets of precision ball screws driven by servo motors, which control the X / Y axis movement respectively. Together with the Z-axis lifting of the third cylinder 19, it achieves three-dimensional precision positioning. The grinding disc 22 eliminates alignment errors through the fine adjustment of the cross slide 20.

[0041] In the specific implementation process, the mobile feeding structure includes: linear slide table 23, lifting frame 24, lifting motor 25, lifting screw 26, moving block 27, fourth cylinder 28, and lifting plate 29;

[0042] The linear slide 23 is fixedly installed on the upper rear side of the base plate 1. The lifting frame 24 is fixedly installed on the output end of the linear slide 23. The lifting motor 25 is fixedly installed on the upper end of the lifting frame 24. One end of the lifting screw 26 is connected to the output end of the lifting motor 25, and the other end is movably connected to the center of the lower end of the lifting frame 24 through a bearing. The moving block 27 is movably fitted on the upper end of the lifting screw 26. The fourth cylinder 28 is fixedly installed on one side of the moving block 27. The lifting plate 29 is fixedly installed at the telescopic end of the fourth cylinder 28.

[0043] After the brake pads are fixed and polished, the linear slide 23 is driven to move the fourth cylinder 28 to the designated position, corresponding to the brake pad. Then, the fourth cylinder 28 is driven to move the lifting plate 29 to the lower end of the brake pad, and the lifting motor 25 in the lifting frame 24 is driven to work. The lifting motor 25 drives the lifting screw 26 to rotate in the lifting frame 24. With the internal thread cooperation between the lifting screw 26 and the moving block 27, the moving block 27 and the fourth cylinder 28 are driven to move upward until the lifting plate 29 lifts the brake pad. Finally, the linear slide 23, the lifting motor 25 and the fourth cylinder 28 cooperate to move the brake pad to the designated position, completing the feeding purpose of the brake pad.

[0044] The linear slide 23 drives the lifting frame 24 to move horizontally to the front of the inlet 30 of the polishing box 4; the lifting motor 25 adjusts the height of the lifting plate 29 to be flush with the inlet 30 through the lifting screw 26; the fourth cylinder 28 pushes the lifting plate 29 to extend horizontally into the inlet 30 to complete the feeding.

[0045] In the specific implementation process, both flip-polishing structures include: a feed inlet 30, a sandblasting machine 31, four limiting sleeves 32, four limiting rods 33, a mounting frame 34, two fifth cylinders 35, a flip motor 36, a flip frame 37, two guide bars 38, two moving rods 39, several mounting rods 40, several positioning grooves 41, a clamping motor 42, a clamping screw 43, two connecting rods 44, and a filter discharge assembly;

[0046] The feed inlet 30 is located on one side of the rear wall of the polishing chamber 4. The sandblasting machine 31 is fixedly installed on the top of the polishing chamber 4. Four limiting sleeves 32 are respectively embedded in the four corners of the upper wall of the polishing chamber 4. The tops of four limiting rods 33 are respectively movably embedded in the four limiting sleeves 32. The upper two sides of the mounting frame 34 are respectively connected to the bottom ends of the four limiting rods 33. Two fifth cylinders 35 are respectively embedded in the upper two sides of the polishing chamber 4, and their telescopic ends are respectively connected to the upper two sides of the mounting frame 34. The tilting motor 36 is fixedly installed on one side of the mounting frame 34. The tilting frame 37 is movably embedded in the mounting frame 34, and one end is connected to the output end of the tilting motor 36. The other end of the tilting frame 37... The end is movably connected to the other side of the mounting frame 34 via a bearing. Two guide bars 38 are respectively installed on both sides of the inside of the tilting frame 37. The two ends of the two moving rods 39 are respectively movably fitted onto the upper ends of the two guide bars 38. Several mounting rods 40 are respectively installed on the upper ends of the two moving rods 39. Several positioning grooves 41 are respectively opened on the side walls of the several mounting rods 40. The clamping motor 42 is fixedly installed on the other side of the tilting frame 37. One end of the clamping screw 43 is connected to the output end of the clamping motor 42. One end of the two connecting rods 44 is respectively movably fitted onto both sides of the upper end of the clamping screw 43, and the other end is respectively connected to one end of the two moving rods 39. The filter discharge assembly is installed at the lower end of the polishing box 4.

[0047] After the brake pads are polished, the polished brake pads are removed by the moving feeding structure and fed into the polishing chamber 4 through the inlet 30 on one side of the rear end of the polishing chamber 4. Multiple brake pads can be installed simultaneously by the engagement of several mounting rods 40 on the upper ends of the two moving rods 39 with the holes on the brake pads. Then, the clamping motor 42 is driven to rotate the clamping screw 43. Under the action of the clamping screw 43 and the two connecting rods 44, the two moving rods 39 move outwards at the upper ends of the two guide bars 38, so that the side walls of the mounting rods 40 are tightly fitted with the inner walls of the holes on the brake pads. The positioning grooves 41 provide stable positioning of the brake pads. Then, the two fifth cylinders 35 are driven to move the mounting frame 34 upwards within the polishing chamber 4. The side wall of the frame 34 is closed to the feed port 30. With the cooperation of four limit rods 33 and four limit sleeves 32, the lifting stability of the mounting frame 34 is ensured. Then, the sandblasting machine 31 at the upper end of the polishing box 4 is driven to work. The upper surface of the brake pad is polished by the sandblasting machine 31. After the single-sided treatment is completed, the flipping motor 36 on one side of the mounting frame 34 is driven. Under the driving action of the flipping motor 36, the flipping frame 37 rotates 180 degrees in the mounting frame 34. Then, the lower wall of the brake pad is sandblasted and polished by the sandblasting machine 31. After the back side is treated, the clamping motor 42 is driven in reverse to separate the holes at both ends of the brake pad from the positioning groove 41. Under its own gravity, the brake pad falls into the filter discharge assembly. The filter discharge assembly filters and recovers the sandblasted material and conveys the polished brake pad out.

[0048] The tilting frame 37 has a hollow frame structure, with the guide bar 38 and the moving rod 39 both located on the back of the brake pad mounting plane. After the tilting motor 36 drives the tilting frame 37 to rotate 180°, the brake pads on the original lower surface are exposed upwards below the sandblasting machine 31, and the guide bar 38 and other components are rotated to the bottom without obstruction.

[0049] Several mounting rods 40 are arranged parallel to each other along the width of the tilting frame 37. The brake pads are inserted into the mounting rods 40 through the positioning holes on both sides to achieve simultaneous installation of multiple pads in the width direction.

[0050] In the specific implementation process, the filter discharge assembly includes: discharge port 45, filter plate 46, flexible baffle 47 and receiving trough 48;

[0051] The discharge port 45 is located at the lower end of the front wall of the polishing box 4. The filter plate 46 is installed at an angle inside the polishing box 4, with one end extending through the discharge port 45. The flexible baffle 47 is fixedly installed on the front wall of the polishing box 4 and located above the discharge port 45. The receiving trough 48 is placed at the front end of the polishing box 4.

[0052] When polishing brake pads, the sandblasting material is filtered by the inclined filter plate 46 and falls to the bottom of the polishing box 4. The sandblasting material is blocked by the flexible baffle 47 to prevent it from splashing. At the same time, the polished brake pads are transported to the receiving trough 48 through the discharge port 45 in cooperation with the filter plate 46.

[0053] In the specific implementation process, a placement groove 49 is machined inside the mounting groove 3. By cooperating with the mounting groove 3, the two ends of the brake pad can be clamped and limited, so as to facilitate the moving feeding structure to pick up and transport the brake pad.

[0054] In the specific implementation process, the clamping screw 43 adopts a bidirectional threaded screw. The connection position between the two connecting rods 44 and the clamping screw 43 is machined with two internal threads. The two internal threads are in opposite directions. Through the cooperation between the bidirectional screw and the internal threads inside the two connecting rods 44, the two connecting rods 44 can move relative to each other at the upper end of the clamping screw 43, ensuring the movement stability of the two moving rods 39, while ensuring that the brake pad is located at the center of the mounting frame 34, and ensuring the polishing effect.

[0055] Compared with traditional positioning hole fixing, the torsion spring hinge positioning block 17 in this case has bidirectional self-adaptive capability:

[0056] When the second cylinder 12 pushes the operating lever 14 downward, the positioning block 17 is automatically unfolded and clamped to the upper edge of the inner hole of the brake pad by the spring force of the torsion spring; when the fixation is released, the operating lever 14 moves upward and squeezes the positioning block 17 into the positioning rod 13, realizing demolding without intervention. This design significantly reduces the clamping stress of the arc-shaped curved workpiece and avoids edge chipping.

[0057] The above technical solutions only embody the preferred technical solutions of the present invention. Any modifications that may be made by those skilled in the art to certain parts thereof embody the principles of the present invention and fall within the protection scope of the present invention.
