Description

Technical Field

[0002] Automobile brake pads are also called automobile brake pads. wheel On a rotating brake drum or brake disc friction Material , where the friction lining and friction pad bear external pressure, generating friction to achieve the purpose of vehicle deceleration;

[0003] When processing brake pads with traditional equipment, traditional fixtures use mechanical pressure plates or one-way ejectors, which can only fix the reference plane and cannot adapt to the curved surface. This causes the workpiece to shift after clamping. Centrifugal force during grinding causes vibration, resulting in edge chipping. Polishing after grinding requires multiple manual flips, resulting in low overall processing efficiency and poor processing consistency of brake pads in the same batch. At the same time, open sandblasting and polishing methods are prone to abrasive splashing, affecting the overall environment of the processing site and even affecting subsequent brake pad processing.

[0004] Although the prior art CN119141412B fixes the brake pads through positioning holes, its clamp is a rigid one-way locking structure that cannot adapt to curved workpieces and lacks a closed automated design for the flipping polishing process.

[0036] When processing automobile brake pads, the staff first moves the device to the designated position, supports the device through the base plate 1, and connects the device to the designated control system. Then the staff places the brake pads to be processed on the upper end of the display rack 2, and places the brake pads through the mounting slots 3 and the display slots 49. Then, the brake pads are moved to the top of the first cylinder 5 by the mobile feeding structure. Then, the first cylinder 5 is driven to work, pushing the mounting sleeve 6 and the two mounting plates 7 to move upward until the two positioning rods 13 are embedded in the through holes on both sides of the brake pads. Then, the two second cylinders 12 are driven, and the two operating rods 14 are driven by the two second cylinders 12 to move downward in the two positioning rods 13. When one end of the two positioning blocks 17 is located in the two operating holes 16, under the reset action of the torsion spring, the two positioning blocks 17 rotate in the two hinge seats 15, and one side of the two positioning blocks 17 passes through the two operating holes 16.

When the brake pad needs to be released, the first cylinder 5 and the second cylinder 12 work synchronously, and the second cylinder 12 pushes the operating rod 14 to move upward. The upper surface of the positioning block 17 located in the operating hole 16 contacts the upper wall surface of the operating hole 16. Under the action of extrusion, the positioning block 17 is flipped in the hinge seat 15 and the torsion spring is squeezed.

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

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

[0039] When the brake pad is 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, and then driving the grinding motor 21 to work, and the grinding disc 22 rotates at high speed to contact the upper surface of the brake pad to grind the brake pad. The cross slide 20 can be used to adjust the position of the grinding disc 22 to ensure the grinding effect of the brake pad.

[0040] The cross slide 20 is composed of two sets of precision ball screws driven by servo motors, which control the X / Y axial movement respectively, and cooperate with the Z-axis lifting of the third cylinder 19 to achieve three-dimensional precision positioning. The grinding disc 22 eliminates the positioning error through the fine adjustment of the cross slide 20.

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

[0042] The linear slide 23 is fixedly installed on the rear side of the upper end 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 mounted on the upper end of the lifting screw 26, the fourth cylinder 28 is fixedly installed on one side of the moving block 27, and the lifting plate 29 is fixedly installed at the telescopic end of the fourth cylinder 28.

[0043] When the brake pad is fixed and polished, the fourth cylinder 28 is moved to the designated position corresponding to the brake pad by driving the linear slide 23, and 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. Under the cooperation of the lifting screw 26 and the internal thread in 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 feed port 30 of the polishing box 4; the lifting motor 25 adjusts the height of the lifting plate 29 to be flush with the feed port 30 through the lifting screw 26; the fourth cylinder 28 pushes the lifting plate 29 horizontally into the feed port 30 to complete the feeding.

[0045] In the specific implementation process, the two flip polishing structures each include: a material 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, a plurality of mounting rods 40, a plurality of positioning slots 41, a clamping motor 42, a clamping screw 43, two connecting rods 44 and a filter discharge assembly;

[0046] The feeding port 30 is opened on one side of the rear wall of the polishing box 4, the sandblasting machine 31 is fixedly installed on the top of the polishing box 4, the four limiting sleeves 32 are respectively embedded in the four corners of the upper wall of the polishing box 4, the tops of the four limiting rods 33 are respectively movably embedded in the four limiting sleeves 32, the two sides of the upper end of the mounting frame 34 are respectively connected to the bottom ends of the four limiting rods 33, the two fifth cylinders 35 are respectively embedded on both sides of the upper end of the polishing box 4, and the telescopic ends are respectively connected to the two sides of the upper end of the mounting frame 34, the flip motor 36 is fixedly installed on one side of the mounting frame 34, the flip frame 37 is movably embedded in the mounting frame 34, and one end is connected to the output end of the flip motor 36, and the other end of the flip frame 37 is connected to the output end of the flip motor 36. The end is movably connected to the other side of the mounting frame 34 through a bearing, and the two guide bars 38 are respectively installed on both sides of the turning frame 37. The two ends of the two moving rods 39 are respectively movably mounted on the upper ends of the two guide bars 38, and a number of mounting rods 40 are respectively installed on the upper ends of the two moving rods 39. A number of positioning grooves 41 are respectively opened at the side walls of the several mounting rods 40. The clamping motor 42 is fixedly installed on the other side of the turning frame 37, and 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 mounted on 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 filtering and discharging assembly is installed at the lower end of the polishing box 4.

[0047] When the brake pad is polished, the polished brake pad is removed by moving the feeding structure, and the brake pad is sent into the polishing box 4 through the feeding port 30 on one side of the rear end of the polishing box 4, and the multiple mounting rods 40 on the upper ends of the two moving rods 39 cooperate with the holes of the brake pad, so that multiple brake pads can be installed synchronously. Then, the clamping motor 42 is driven to work, and the clamping motor 42 drives the clamping screw 43 to rotate. Under the cooperation of the clamping screw 43 and the two connecting rods 44, the two moving rods 39 are driven to move outward at the upper ends of the two guide bars 38, so that the side walls of the multiple mounting rods 40 are tightly fitted with the inner wall of the hole of the brake pad, and the brake pad is stably limited by the positioning groove 41. Then, the two fifth cylinders 35 are driven to drive the mounting frame 34 to move upward in the polishing box 4 through the two fifth cylinders 35. The side wall of the frame 34 closes the feed inlet 30, and the cooperation of the four limiting rods 33 and the four limiting sleeves 32 ensures the lifting stability of the mounting frame 34, and then drives the sandblasting machine 31 at the upper end of the polishing box 4 to work, and the upper surface of the brake pad is polished by the sandblasting machine 31. When the single-side processing is completed, the flip motor 36 on one side of the mounting frame 34 is driven. Under the driving action of the flip motor 36, the flip frame 37 is rotated 180 degrees in the mounting frame 34, and then the lower wall surface of the brake pad is sandblasted and polished by the sandblasting machine 31. When the back surface processing is completed, the clamping motor 42 is driven in the reverse direction to separate the holes at both ends of the brake pad from the positioning groove 41, and under the action of its own gravity, it falls into the filtering and discharging assembly, and the sandblasting material is filtered and recovered by the filtering and discharging assembly, and the polished brake pad is conveyed and discharged;

[0048] The tilting frame 37 is a hollow frame structure, with guide bars 38 and movable rods 39 located behind the brake pad mounting surface. After the tilting motor 36 drives the tilting frame 37 to rotate 180 degrees, the brake pad's lower surface is exposed upwards under the sandblasting machine 31, and the guide bars 38 and other components are rotated to the bottom, leaving them unobstructed.

[0049] Several mounting rods 40 are arranged in parallel along the width direction of the flip frame 37 , and the brake pads are inserted into the mounting rods 40 through the positioning holes on both sides, so that multiple brake pads can be installed synchronously in the width direction.

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

[0051] The discharge port 45 is opened at the lower end of the front wall of the polishing box 4, the filter plate 46 is installed obliquely in the polishing box 4, and one end passes through the discharge port 45, the flexible baffle 47 is fixedly installed on the front wall of the polishing box 4, and is located at the upper end of the discharge port 45, and the receiving trough 48 is placed at the front end of the polishing box 4.

[0052] When the brake pad is being polished, the sandblasting material is filtered by the inclined filter plate 46 and falls to the lower end 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 pad is transported to the receiving trough 48 through the cooperation of the discharge port 45 and the filter plate 46.

[0053] In the specific implementation process, a placement groove 49 is processed in the installation groove 3. By cooperating with the installation groove 3, the two ends of the brake pad can be clamped and limited, so that the brake pad can be picked up and transported by the mobile feeding structure.

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

[0055] Compared with the traditional positioning hole fixation, the torsion spring hinged positioning block 17 in this case has bidirectional adaptive capabilities:

[0056] When the second cylinder 12 pushes the operating rod 14 downward, the positioning block 17 is automatically expanded by the torsion spring force to clamp the upper edge of the inner hole of the brake pad; when the fixation is released, the operating rod 14 moves upward to squeeze the positioning block 17 into the positioning rod 13, realizing non-intervention demoulding. This design significantly reduces the clamping stress of the curved surface workpiece and avoids edge chipping.

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