Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake pad technology, and in particular to a tooling for processing automotive brake pads. Background Technology
[0002] Brake pads, also known as brake discs, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads. During the brake pad manufacturing process, drilling is required to create tightening holes, allowing the brake pads to be effectively secured with bolts.
[0003] Chinese utility model patent CN211991047U discloses a drilling machine for processing brake pads, including a drilling machine frame, a support frame, a drilling mechanism, and a clamping mechanism. The support frame is fixed to the top surface of the drilling machine frame, and the drilling mechanism is installed inside the support frame. The clamping mechanism is installed at the bottom of the drilling machine frame. The clamping mechanism includes a second motor, a screw, and a pressure plate. The second motor is fixed to the bottom of the drilling machine frame via a bracket. The output end of the second motor is connected to the screw, and the free end of the screw is connected to the bottom of the drilling machine frame via a rotating shaft. A threaded sleeve is installed on the screw, and support rods are connected to both ends of the threaded sleeve. The pressure plate is L-shaped and placed on both sides of the processing table. The bottom end of the pressure plate passes through the drilling machine frame and is connected to the support rods. When a brake pad is placed on the processing table, the second motor drives the screw to rotate. The threaded sleeve engages with the screw and moves along the screw. The threaded sleeve drives the support rods to move, causing the support rods to drive the pressure plate, which then clamps the brake pad.
[0004] Regarding the aforementioned technologies, the inventors believe the following drawbacks exist: When using the device, the positioning of the brake pads relies entirely on manual adjustment by the operator, followed by clamping and drilling using a pressure plate. However, since manual positioning of the brake pads by the operator may result in errors, this can lead to deviations in the drilling positions, thus affecting the correct assembly of the brake pads. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides a tooling for processing automotive brake pads.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tooling for processing automotive brake pads, including a frame, a worktable at the top of the frame, a fixed plate vertically arranged on the worktable, a sliding plate horizontally slidably arranged on the worktable, the sliding plate being parallel to the fixed plate, a first hydraulic cylinder horizontally arranged on the worktable, the piston rod end of the first hydraulic cylinder being connected to the sliding plate, a placement groove arranged on the side of the fixed plate adjacent to the sliding plate, a lifting plate vertically slidably arranged on the fixed plate, a pressure plate vertically arranged at the bottom of the lifting plate corresponding to the placement groove, two through holes horizontally spaced on the fixed plate, the two through holes communicating with the placement groove, a through hole corresponding to the through hole on the sliding plate, and a drilling assembly arranged on the worktable.
[0007] By adopting the above technical solution, a frame, worktable, fixed plate, and sliding plate are set up. The lifting plate slides upward, and then the brake pad is placed into the placement slot. The lifting plate is then released, causing it to descend, which in turn causes the pressure plate to descend, pressing the brake pad and initially fixing it to ensure precise positioning. This ensures the accuracy of the drilling position and thus guarantees precise assembly of the brake pad. Next, the first hydraulic cylinder is activated, pushing the sliding plate towards the fixed plate, where it contacts the brake pad and clamps it between the fixed plate and the sliding plate. Then, a drilling assembly drills a hole in the brake pad. Through holes and via holes are provided for the drill bit of the drilling assembly to pass through.
[0008] Furthermore, the drilling assembly includes a sliding seat slidably mounted on the worktable, with two grooves spaced apart on the sliding seat. The length direction of the grooves is perpendicular to the sliding direction of the sliding seat. A slider is provided in the groove, and a moving block is provided on both sliders. A drilling machine is provided on the moving block, and a second hydraulic cylinder is horizontally mounted on the side of the moving block away from the fixed plate. The piston rod of the second hydraulic cylinder is connected to the moving block.
[0009] By adopting the above technical solution, a sliding seat, a moving block, a drilling machine, and a second hydraulic cylinder are set up. The sliding seat is slid so that the drill bit of the drilling machine is aligned with the through hole. Then, the moving block is pushed by the second hydraulic cylinder to move, which drives the drilling machine to move. After the drill bit of the drilling machine passes through the through hole, it contacts the brake pad and drills the brake pad. Then, the end of the drill bit of the drilling machine passes through the brake pad and is placed in the through hole, ensuring that the brake pad is completely penetrated.
[0010] Furthermore, the workbench is provided with upright plates at intervals, and two slide rods are provided at intervals between two upright plates. Two slide holes are provided at intervals on the sliding seat, and the slide holes are slidably connected to the corresponding slide rods.
[0011] By adopting the above technical solution, and setting up a vertical plate and a sliding rod, the stability of the sliding seat is ensured.
[0012] Furthermore, a threaded rod is rotatably provided between the two upright plates. The threaded rod is parallel to the sliding rod. The sliding seat is helically connected to the threaded rod through a threaded hole. A drive motor is horizontally provided on the worktable. The output shaft of the drive motor is connected to the end of the threaded rod.
[0013] By adopting the above technical solution, a threaded rod and a drive motor are set up. The drive motor drives the threaded rod to rotate. Since the sliding seat is helically connected to the threaded rod through the threaded hole, when the threaded rod rotates, it drives the sliding seat to slide along the length of the threaded rod, making the control of the drilling machine position more precise.
[0014] Furthermore, the top of the fixed plate is provided with two uprights spaced apart, and the lifting plate has two vertically spaced circular holes, which are slidably connected to the corresponding uprights. The lifting plate is provided with a handle.
[0015] By adopting the above technical solution, setting up uprights and round holes ensures the stability of the sliding of the lifting plate, and pulling the handle drives the lifting plate to slide, making it easy to operate.
[0016] Furthermore, a top plate is provided at the top of the upright, and a compression spring is sleeved on the upright between the top plate and the lifting plate. The upper end of the compression spring is connected to the top plate, and the lower end is connected to the lifting plate.
[0017] By adopting the above technical solution, a top plate and a compression spring are set up. The compression spring provides a downward thrust to ensure the downward thrust of the pressure plate, thereby ensuring that the brake pads are initially and securely fixed.
[0018] Furthermore, the fixed plate is provided with first mounting seats on both sides, and two second mounting seats are provided at intervals on the side of the worktable away from the drilling assembly. A guide rod is provided between the first mounting seat and the corresponding second mounting seat. A connecting seat is provided on both sides of the sliding plate, and a guide hole is horizontally opened on the connecting seat. The guide hole is slidably connected to the corresponding guide rod.
[0019] By adopting the above technical solution, a first mounting base, a second mounting base, and a guide rod are set up. When the sliding plate slides, it drives the connecting base to slide on the guide rod, thus ensuring the stability of the sliding plate.
[0020] Furthermore, the bottom surface of the pressure plate is an arc surface, and a rubber sheet is provided on the bottom surface of the pressure plate.
[0021] By adopting the above technical solution, the bottom surface of the pressure plate is made into an arc surface, which makes the shape of the pressure plate and the top of the brake pad fit better. In addition, the rubber sheet is set so that the rubber sheet contacts the brake pad, which improves the fixing effect of the brake pad.
[0022] Furthermore, the width of the bottom of the placement groove is less than the thickness of the brake pad.
[0023] By adopting the above technical solution, the sliding plate surface only contacts the brake pad and not the fixed plate surface, ensuring that the pressure on the brake pad is not dispersed by the fixed plate and that the fixing effect on the brake pad is better.
[0024] In summary, this utility model has the following beneficial effects: It includes a frame, worktable, fixed plate, and sliding plate. The lifting plate slides upwards, and then the brake pad is placed in the placement slot. The lifting plate is then released, causing it to descend and pull the pressure plate down. The pressure plate presses down on the brake pad, initially fixing it and ensuring its precise position to guarantee the accuracy of the drilling position, thus ensuring precise assembly of the brake pad. Subsequently, the first hydraulic cylinder is activated, pushing the sliding plate towards the fixed plate, where it contacts the brake pad, clamping it between the fixed plate and the sliding plate. Then, a drilling assembly drills a hole in the brake pad. Through holes and via holes are provided for the drill bit of the drilling assembly to pass through. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] like Figure 1-4 As shown in the embodiment of this application, a tooling for processing automotive brake pads is disclosed, including a frame 10, a worktable 11, a fixed plate 20, and a sliding plate 30. The worktable 11 is disposed on the top of the frame 10, and the fixed plate 20 is vertically disposed on the worktable 11. The sliding plate 30 is horizontally slidably disposed on the worktable 11, and the sliding plate 30 is parallel to the fixed plate 20. A first hydraulic cylinder 12 is horizontally disposed on the worktable 11, and the piston rod end of the first hydraulic cylinder 12 is connected to the sliding plate 30. The first hydraulic cylinder 12 pushes the sliding plate 30 to slide. A placement groove 21 is provided on the side of the fixed plate 20 adjacent to the sliding plate 30. The shape of the lower part and both sides of the placement groove 21 matches the shape of the brake pad. The brake pad is placed in the placement groove 21, with the bottom of the brake pad contacting the bottom of the placement groove 21, and both ends and one side of the brake pad contacting the groove wall. A lifting plate 40 is vertically slidably mounted on the fixed plate 20. A pressure plate 41 is vertically mounted on the bottom of the lifting plate 40 corresponding to the placement groove 21. Two through holes 22 are horizontally spaced on the fixed plate 20, and the two through holes 22 communicate with the placement groove 21. The positions of the through holes 22 correspond to the positions where the brake pads need to be drilled. A through hole 31 is provided on the sliding plate 30 corresponding to the through hole 22. A drilling assembly 50 is provided on the worktable 11.
[0032] The lifting plate 40 slides upward, placing the brake pad into the placement slot 21. The lifting plate 40 is then released, causing it to descend and lower the pressure plate 41, which presses down on the brake pad, initially fixing it and ensuring precise positioning to guarantee accurate hole placement and precise brake pad assembly. The first hydraulic cylinder 12 is then activated, pushing the sliding plate 30 towards the fixed plate 20, where it contacts the brake pad and clamps it between the fixed plate 20 and the sliding plate 30. The drilling assembly 50 then drills a hole in the brake pad. Through holes 22 and 31 allow the drill bit of the drilling assembly 50 to pass through.
[0033] Specifically, the bottom surface of the pressure plate 41 is an arc surface, which makes the pressure plate 41 fit the shape of the top of the brake pad better. A rubber sheet 46 is provided on the bottom surface of the pressure plate 41, so that the rubber sheet 46 contacts the brake pad, which improves the fixing effect of the brake pad. The width of the bottom of the placement groove 21 is less than the thickness of the brake pad, so that the surface of the sliding plate 30 only contacts the brake pad and does not contact the surface of the fixing plate 20, ensuring that the pressure on the brake pad is not dispersed by the fixing plate 20, which improves the fixing effect of the brake pad.
[0034] Two uprights 42 are spaced apart on the top of the fixed plate 20. Two spaced circular holes are vertically arranged on the lifting plate 40, and these holes are slidably connected to the corresponding uprights 42. A handle 43 is provided on the lifting plate 40. The uprights 42 and the circular holes ensure the stability of the lifting plate 40's sliding motion, and pulling the handle 43 causes the lifting plate 40 to slide, facilitating operation. A top plate 44 is provided on the top of the uprights 42. A compression spring 45 is fitted onto the uprights 42 located between the top plate 44 and the lifting plate 40. The upper end of the compression spring 45 is connected to the top plate 44, and the lower end is connected to the lifting plate 40. The compression spring 45 provides a downward thrust, ensuring the downward thrust of the pressure plate 41, thereby ensuring the brake pads are initially and securely fixed.
[0035] First mounting seats 70 are provided on both sides of the fixed plate 20. Two second mounting seats 71 are provided at intervals on the side of the worktable 11 away from the drilling assembly 50. A guide rod 72 is provided between the first mounting seat 70 and the corresponding second mounting seat 71. Connecting seats 73 are provided on both sides of the sliding plate 30. A guide hole 74 is horizontally opened on the connecting seat 73. The guide hole 74 is slidably connected to the corresponding guide rod 72. When the sliding plate 30 slides, it drives the connecting seat 73 to slide on the guide rod 72, ensuring the stability of the sliding plate 30.
[0036] In setup, the drilling assembly 50 includes a sliding seat 51 horizontally slidably mounted on the worktable 11. Two grooves 52 are spaced apart on the sliding seat 51, with the length of the grooves 52 perpendicular to the sliding direction of the sliding seat 51. A slider 53 is installed within each groove 52, and a moving block 54 is shared by the two sliders 53, allowing the moving block 54 to slide along the length of the grooves 52. A drilling machine 55 is horizontally mounted on the moving block 54. A second hydraulic cylinder 56 is horizontally mounted on the side of the moving block 54 away from the fixed plate 20. The piston rod of the second hydraulic cylinder 56 is connected to the moving block 54. By sliding the sliding seat 51, the drill bit of the drilling machine 55 is aligned with the through hole 22. The second hydraulic cylinder 56 then pushes the moving block 54, moving the drilling machine 55, causing the drill bit of the drilling machine 55 to pass through the through hole 22 and contact the brake pad, drilling the brake pad. The end of the drill bit then passes through the brake pad and is placed inside the through hole 31, ensuring the brake pad is completely penetrated.
[0037] In the specific setup, the worktable 11 is provided with spaced vertical plates 60, and two sliding rods 61 are spaced between the two vertical plates 60. Both ends of the sliding rods 61 are fixedly connected to the corresponding vertical plates 60. The sliding seat 51 has two spaced sliding holes 57, which are slidably connected to the corresponding sliding rods 61 to ensure the stability of the sliding seat 51. A threaded rod 62 is rotatably provided between the two vertical plates 60, and both ends of the threaded rod 62 are rotatably connected to the corresponding vertical plates 60. The threaded rod 62 is parallel to the sliding rods 61. The sliding seat 51 is helically connected to the threaded rod 62 through a threaded hole. A drive motor 63 is horizontally provided on the worktable 11. One end of the threaded rod 62 passes through the vertical plate 60, and the output shaft of the drive motor 63 is connected to the end of the threaded rod 62 that passes through the vertical plate 60. The drive motor 63 drives the threaded rod 62 to rotate. Since the sliding seat 51 is helically connected to the threaded rod 62 through the threaded hole, when the threaded rod 62 rotates, it drives the sliding seat 51 to slide along the length of the threaded rod 62, making the control of the position of the drilling machine 55 more precise.
[0038] The working principle of a car brake pad processing fixture in this embodiment is as follows: Pulling the handle 43 causes the lifting plate 40 and pressure plate 41 to rise, compressing the compression spring 45. Then, the worker places the brake pad in the placement slot 21 and holds it with one hand. Then, the handle 43 is released, the compression spring 45 releases its thrust, and pushes the lifting plate 40 and pressure plate 41 down. The rubber sheet 46 contacts the top of the brake pad. At this time, the brake pad is initially fixed, and the worker releases the hand holding the brake pad. The first cylinder is activated to move the sliding plate 30, causing it to contact the brake pad and clamp it between the fixed plate 20 and the sliding plate 30. Then, the drive motor 63 is activated to drive the threaded rod 62 to rotate, causing the sliding seat 51 to slide and align the drill bit of the drilling machine 55 with one of the through holes 22. Subsequently, the second hydraulic cylinder 56 pushes the moving block 54 and the drilling machine 55 to move, so that the drill bit of the drilling machine 55 passes through the through hole 22 and contacts the brake pad to drill a hole in the brake pad. Then, the end of the drill bit of the drilling machine 55 passes through the brake pad and is placed in the through hole 31 to ensure that the brake pad is completely penetrated. Then, the second hydraulic cylinder 56 and the drive motor 63 work together to move the drilling machine 55 to the second through hole 22 to drill a hole.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
