Description

Technical Field

[0001] This application relates to the field of metal sheet drilling equipment, and in particular to a fully automatic drilling equipment for brake pad steel backing. Background Technology

[0002] Currently, the holes on brake disc backplates are mainly used for weight reduction, enhanced heat dissipation, ventilation, and aesthetics. These holes are usually not through holes (not penetrating the friction surface) but blind holes, and require high positional accuracy, depth consistency, and processing efficiency. Existing fully automated steel backplate drilling equipment typically uses a robotic arm to transport the steel backplate to a worktable, where a conveying mechanism transports the steel backplate to different drilling machines for drilling, and then collects the drilled steel backplates.

[0003] Related technology can be found in patent application CN217192723U, which discloses a drilling device for the steel back of brake pads, including: a frame with a rotating disc rotatably mounted thereon; a plurality of drilling stations arranged along the circumferential direction of the rotating disc; a feeding mechanism, including a feeding station for placing the steel back and a feeding assembly for moving the steel back from the feeding station to the drilling station; and a drilling mechanism having several sets of drill bits, the drill bits extending toward the drilling station.

[0004] Regarding the aforementioned technologies, when drilling holes in the steel backing, the feeding gripper grabs the steel backing and the drive structure transports it to the drilling plate. During the process of transporting the steel backing to the drilling plate, due to the rotation angle of the drilling plate or the insufficient precision of the drive structure's transport position, it is not easy to transport the steel backing to a specific area of ​​the drilling plate. The protruding part of the steel backing is not easy to accurately engage in the groove, and the steel backing is prone to slight displacement, resulting in insufficient precision in the subsequent drilling position. Therefore, there is an urgent need for a fully automatic drilling device for brake pad steel backing to solve the above technical problems. Summary of the Invention

[0005] To ensure more precise drilling of the steel backing, this application provides a fully automatic drilling device for brake pad steel backing.

[0006] This application provides a fully automatic drilling device for the steel backing of brake pads, which adopts the following technical solution: An automatic drilling device for brake pad steel backing includes a base, a turntable rotatably connected to the upper surface of the base, the turntable having several grooves for engaging the steel backing, the grooves being evenly distributed along the circumference of the turntable, a feeding mechanism for conveying the steel backing to the grooves on the turntable on one side of the base, two drilling mechanisms for drilling holes in the steel backing on the upper surface of the base, and a discharging mechanism for driving the steel backing to separate from the turntable. The feeding mechanism, the two drilling mechanisms, and the discharging mechanism are evenly distributed along the circumference of the turntable, and two supports are provided between the feeding mechanism and the base. The support base has push rods on both sides of the groove for gently pushing the two ends of the steel back. The push rods are horizontally set and slidably connected to the support base. The end of the push rod away from the groove is fixedly connected to a contact plate. The contact plate is coaxially connected to the push rod. A return spring is fixedly connected to one side of the contact plate. The return spring is horizontally set. The end of the return spring away from the contact plate is fixedly connected to the support base. The side of the contact plate away from the push rod is provided with a drive assembly for driving the contact plate to move laterally. The support base is provided with an alternating assembly for driving the drive assembly to alternately push the contact plate.

[0007] By adopting the above technical solution, the support base supports the push rod. The feeding mechanism conveys the steel back to the groove of the turntable. The alternating component drives the drive component to alternately push the contact plate. The contact plate moves laterally, which in turn drives the push rod to move laterally. The push rod gently pushes the steel back to fine-tune its position. The two push rods respectively fine-tune the left and right of the steel back, thus ensuring that the steel back is accurately engaged in the groove of the turntable. The rotation of the turntable drives the steel back to the drilling mechanism for drilling, which helps to improve the accuracy of the drilling position, reduce errors, and improve product quality. During the lateral movement of the contact plate, the return spring is compressed and contracted. After the steel back is fine-tuned, the return spring rebounds, which in turn drives the contact plate to return to its original position, and simultaneously drives the push rod to return to its original position, thus facilitating subsequent fine-tuning of the position of different steel backs. The unloading mechanism separates the drilled steel back from the turntable, thus facilitating the collection of the steel back.

[0008] Optionally, the driving assembly includes a push rod for pushing the abutting circular plate to move laterally, a connecting block for driving the push rod to swing, a transmission rod for driving the connecting block to swing, a driving block for driving the transmission rod to rotate, and a lifting rod for driving the driving block to swing. The lifting rod is vertically arranged, with its upper end abutting one end of the driving block. The driving block is horizontally arranged, with its end away from the lifting rod fixedly connected to the transmission rod. The transmission rod is perpendicular to the driving block, horizontally arranged, and rotatably connected to the support base. The end of the transmission rod away from the driving block is fixedly connected to the connecting block. The transmission rod is perpendicular to the connecting block, with the side of the connecting block away from the transmission rod fixedly connected to the push rod. The push rod is horizontally arranged, with one end abutting the side of the abutting circular plate away from the push rod.

[0009] By adopting the above technical solution, when the position of the steel back needs to be fine-tuned, the lifting rod rises, causing one end of the driving block to swing, which in turn drives the transmission rod to rotate. The transmission rod drives the connecting block to swing, the connecting block drives the top rod to swing, and the top rod drives the contact circular plate to move laterally, thereby achieving fine-tuning of the position of the steel back.

[0010] Optionally, the alternating assembly includes two cams for driving the lifting rod to rise and fall, a rotating rod for driving the cams to rotate, and a drive motor for driving the rotating rod to rotate. The drive motor is fixedly connected to the support base, and the output shaft of the drive motor is fixedly connected to the rotating rod coaxially. The rotating rod is horizontally set and rotatably connected to the two support bases. Both cams are fixedly connected to the rotating rod coaxially. The cams are slidably connected to the end of the lifting rod away from the driving block, and the protruding parts of the two cams face opposite directions.

[0011] By adopting the above technical solution, when the position of the steel back needs to be fine-tuned, the drive motor is started. The output shaft of the drive motor drives the rotating rod to rotate, and the rotating rod drives the two cams to rotate. When the protruding part of one cam abuts against the lifting rod, the lifting rod rises and thus fine-tunes the steel back. When the rotating rod rotates 180 degrees, the protruding part of the other cam abuts against the lifting rod, thereby realizing the alternating fine-tuning of the left and right sides of the steel back.

[0012] Optionally, the feeding mechanism includes an electromagnetic chuck for adsorbing the steel back, a lifting cylinder for driving the electromagnetic chuck to rise and fall, a transverse block for connecting the lifting cylinder, a support frame for supporting the transverse block, a rotating screw for driving the transverse block to move laterally, and a placement plate for placing the steel back. The placement plate is fixedly connected to the support frame and is horizontally positioned. The rotating screw is rotatably connected to the support frame and threadedly connected to the transverse block. The transverse block is slidably connected to the support frame. The lifting cylinder is fixedly connected to the transverse block, and the piston rod of the lifting cylinder is fixedly connected to the electromagnetic chuck.

[0013] By adopting the above technical solution, the placement plate is used to store the steel backing, and the support frame supports the placement plate, the transverse block, and the rotating screw. When the steel backing is conveyed, the piston rod of the lifting cylinder extends, causing the electromagnetic chuck to descend. The electromagnetic chuck attracts the steel backing on the placement plate. The piston rod of the lifting cylinder retracts, causing the electromagnetic chuck to lift the steel backing. The rotating screw rotates, causing the transverse block to move laterally, thereby conveying the steel backing to the top of the groove. Then, the lifting cylinder is activated to drive the electromagnetic chuck to descend. The electromagnetic chuck is de-energized, thus conveying the steel backing to the groove to complete the loading process. This helps to reduce the number of workers who need to load the steel backing and realizes automated processing of the steel backing.

[0014] Optionally, a fixed seat is fixedly connected to the lower end of the support frame. A rotating motor is fixedly connected to the side of the fixed seat away from the base. A linkage rod is coaxially connected to the output shaft of the rotating motor. The linkage rod is rotatably connected to the fixed seat. The linkage rod is connected to a drive vertical rod through a bevel gear pair. The drive vertical rod is rotatably connected inside the support frame. The drive vertical rod is connected to a rotating screw through a bevel gear pair. A hinge seat is provided at the lower end of the support seat. Both support seats are fixedly connected to the hinge seat. The side of the hinge seat away from the base is hinged to the fixed seat. A drive gear is coaxially connected to the linkage rod. The drive gear meshes with a drive rack. A lifting block is fixedly connected to the upper end of the drive rack. The lifting block is slidably connected to the fixed seat. One end of the lifting block passes through the fixed seat and is slidably connected to the lower end face of the hinge seat. The lifting block is located on the side of the hinge seat close to the base.

[0015] By adopting the above technical solution, the fixed seat supports the support frame. When the steel backing needs to be conveyed, the rotating motor is started. The rotating motor drives the linkage rod to rotate, which in turn drives the drive vertical rod to rotate via a bevel gear pair. The drive vertical rod, in turn, drives the rotating screw to rotate via the bevel gear pair, thereby realizing the conveying of the steel backing. During the rotation of the linkage rod, the drive gear rotates, which in turn drives the drive rack to descend. The drive rack drives the lifting block to descend, which in turn causes the hinge seat to swing. When the lifting block descends to its lowest point, it causes the upper end of the support seat to approach the turntable, moving the push rod to both sides of the groove. At this time, the steel backing is conveyed to the top of the groove. The push rod is positioned while the steel backing is being conveyed, which helps to improve processing efficiency. After the steel backing is fine-tuned, the output shaft of the rotating motor rotates in the opposite direction, which in turn drives the lifting block to rise. The lifting block causes the hinge seat to swing, which in turn causes the support seat to move obliquely upward, moving the push rod away from the turntable. This facilitates the rotation of the steel backing to the drilling mechanism and helps to reduce the phenomenon of the push rod obstructing the rotation of the steel backing.

[0016] Optionally, a connecting plate is fixedly connected to the upper end of the base, and two clamping cylinders are fixedly connected to the connecting plate. The clamping cylinders are located near the drilling mechanism on the connecting plate and are vertically arranged. The piston rod of the clamping cylinder is fixedly connected to a pressure plate for clamping the steel back and is horizontally arranged.

[0017] By adopting the above technical solution, the connecting plate supports the clamping cylinder. After the steel back is finely adjusted, the turntable drives the steel back to rotate to the drilling mechanism, and the clamping cylinder is activated. The piston rod of the clamping cylinder extends, driving the pressure plate to clamp the steel back, which helps to reduce the phenomenon of displacement during the drilling process of the steel back.

[0018] Optionally, the drilling mechanism includes a drilling machine for drilling holes in the steel back and an electric slide rail for driving the drilling machine to move laterally towards the steel back. The electric slide rail is arranged along the diameter direction of the turntable, and is slidably connected to the drilling machine. The electric slide rail is horizontally arranged on the upper surface of the base.

[0019] By adopting the above technical solution, when the steel backing rotates to the drilling machine via the turntable, the electric slide rail is activated, and the electric slide rail drives the drilling machine to move laterally to the steel backing to drill holes in the steel backing.

[0020] Optionally, the feeding mechanism includes a push plate for pushing the steel back, a propulsion cylinder for driving the push plate to move laterally, and a slide plate for guiding and conveying the steel back. The push plate is horizontally arranged, the propulsion cylinder is fixedly connected to the connecting plate, the propulsion cylinder is arranged along the diameter direction of the turntable, the piston rod of the propulsion cylinder is fixedly connected to the push plate, and the slide plate is fixedly connected to the base and is inclined.

[0021] By adopting the above technical solution, after the steel back is drilled, the turntable transports the steel back to the slide plate, the propulsion cylinder is activated, the piston rod of the propulsion cylinder extends, driving the push plate to move laterally, and the push plate pushes the steel back onto the slide plate, thus facilitating the collection of the steel back.

[0022] Optionally, a toothed ring is fixedly connected to the lower end face of the turntable. The toothed ring is horizontally arranged and rotatably connected to the base. The toothed ring meshes with a transmission gear. A transmission motor is fixedly connected inside the base. The output shaft of the transmission motor is coaxially and fixedly connected to the transmission gear.

[0023] By adopting the above technical solution, when the steel back needs to be conveyed, the drive motor is started. The output shaft of the drive motor drives the drive gear to rotate, the drive gear drives the gear ring to rotate, and then the gear ring drives the turntable to rotate, which facilitates the conveying of the steel back.

[0024] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting two push rods, the push rods gently push the steel back to fine-tune its position. The two push rods fine-tune the left and right sides of the steel back respectively, so that the steel back is accurately engaged in the groove of the turntable. The rotation of the turntable drives the steel back to the drilling machine for drilling, which helps to improve the accuracy of the drilling position, reduce errors, and improve product quality. 2. By setting two cams, when the position of the steel back needs to be fine-tuned, the drive motor is started. The output shaft of the drive motor drives the rotating rod to rotate, and the rotating rod drives the two cams to rotate. When the protruding part of one cam abuts against the lifting rod, the lifting rod rises and thus fine-tunes the steel back. When the rotating rod rotates 180 degrees, the protruding part of the other cam abuts against the lifting rod, thus realizing the alternating fine-tuning of the left and right sides of the steel back. 3. By setting up a clamping cylinder, the turntable drives the steel back to rotate to the drilling mechanism, and the clamping cylinder is activated. The piston rod of the clamping cylinder extends, driving the pressure plate to clamp the steel back, which helps to reduce the phenomenon of displacement during the drilling process of the steel back.

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a fully automatic drilling device for the steel back of brake pads.

[0033] Reference Figure 1 An automatic drilling device for brake pad steel backing includes a conveying mechanism 1, a feeding mechanism 2, a fine-tuning mechanism 3, two drilling mechanisms 4, and a discharging mechanism 5. The feeding mechanism 2, the two drilling mechanisms 4, and the discharging mechanism 5 are arranged sequentially around the conveying mechanism 1. The fine-tuning mechanism 3 is located between the feeding mechanism 2 and the conveying mechanism 1. The feeding mechanism 2 conveys the steel backing onto the conveying mechanism 1, the fine-tuning mechanism 3 fine-tunes the position of the steel backing, the conveying mechanism 1 conveys the steel backing to the drilling mechanism 4, the drilling mechanism 4 drills holes in the steel backing, and after the steel backing is drilled, the discharging mechanism 5 conveys the steel backing, thus completing the automatic drilling of the steel backing.

[0034] Reference Figure 1 and Figure 2 The conveying mechanism 1 includes a base 11, a turntable 12, a gear ring 13, a transmission gear 14, a transmission motor 15, a connecting plate 16, two clamping cylinders 17, and two pressure plates 18. The turntable 12 is rotatably connected to the upper end face of the base 11 and is horizontally positioned. The gear ring 13 is fixedly connected to the lower end face of the turntable 12 and is horizontally positioned. The gear ring 13 meshes with the transmission gear 14, and the transmission gear 14 is coaxially and fixedly connected to the output shaft of the transmission motor 15. 5 is set inside the base 11 and fixedly connected to the base 11. The turntable 12 has four grooves 121 for engaging the steel back. The grooves 121 are evenly arranged around the circumference of the turntable 12. When the steel back needs to be transported, the steel back is placed in the groove 121 of the turntable 12, and the drive motor 15 is started. The output shaft of the drive motor 15 drives the drive gear 14 to rotate, the drive gear 14 drives the gear ring 13 to rotate, and then the gear ring 13 drives the turntable 12 to rotate, which facilitates the transport of the steel back.

[0035] Reference Figure 1 and Figure 2 The connecting plate 16 is fixedly connected to the upper surface of the base 11. The connecting plate 16 is coaxially arranged with the turntable 12 and is located above the turntable 12. The clamping cylinder 17 is fixedly connected to the connecting plate 16 and is vertically arranged. Two clamping cylinders 17 are arranged on the connecting plate 16 near the drilling mechanism 4. The piston rod of the clamping cylinder 17 is fixedly connected to the pressure plate 18, which is horizontally arranged. The connecting plate 16 supports the clamping cylinder 17. Before drilling the steel backing, the clamping cylinder 17 is activated, and the piston rod of the clamping cylinder 17 extends, causing the pressure plate 18 to clamp the steel backing, thereby helping to reduce the phenomenon of displacement during the drilling process.

[0036] Reference Figure 1 and Figure 3The feeding mechanism 2 includes an electromagnetic chuck 21, a lifting cylinder 22, a transverse block 23, a support frame 24, a rotating screw 25, and a placement plate 26. The placement plate 26 is fixedly connected to the support frame 24 and is horizontally arranged. The rotating screw 25 is rotatably connected to the support frame 24 and is horizontally arranged. The transverse block 23 is threadedly connected to the rotating screw 25 and is slidably connected to the support frame 24. The transverse block 23 is fixedly connected to the lifting cylinder 22 and is vertically arranged. The piston rod of the lifting cylinder 22 is fixedly connected to the electromagnetic chuck 21. The placement plate 26 is used to store the steel backing. The support frame 24 supports the placement plate 26, the transverse block 23, and the rotating screw 25. When the steel backing is conveyed, the piston rod of the lifting cylinder 22 extends, causing the electromagnetic chuck 21 to descend. The electromagnetic chuck 21 attracts the steel backing on the placement plate 26. The piston rod of the lifting cylinder 22 retracts, and the electromagnetic chuck 21 drives the steel backing to rise. The rotating screw 25 rotates, causing the transverse block 23 to move laterally, thereby conveying the steel backing to the top of the groove 121. Then, the lifting cylinder 22 is activated to drive the electromagnetic chuck 21 to descend. The electromagnetic chuck 21 is de-energized, thus conveying the steel backing to the groove 121 to complete the loading process. This helps to reduce the number of workers who need to load the steel backing and realizes automated processing of the steel backing.

[0037] Reference Figure 1 and Figure 4The fine-tuning mechanism 3 includes two support seats 31, two push rods 32, two abutting circular plates 33, two return springs 34, two sets of drive components 35, and an alternating component 36. Each drive component 35 includes a push rod 351, a connecting block 352, a transmission rod 353, a driving block 354, and a lifting rod 355. The alternating component 36 includes two cams 361, a rotating rod 362, and a drive motor 363. The drive motor 363 is fixedly connected to one of the support seats 31. The output shaft of the drive motor 363 is coaxially fixedly connected to the rotating rod 362. The rotating rod 362 is horizontally positioned and rotatably connected to both support seats 31. Both cams 361 are coaxially fixedly connected to the rotating rod 362, with their protruding portions facing opposite directions. Each cam 361 is slidably connected to one of the two lifting rods 355. The lifting rods 355 are vertically positioned and slidably connected to the support seats 31. The upper end of the lifting rod 355 abuts against one end of the driving block 354. The drive block 354 is horizontally positioned, with one end of the drive block 354 away from the lifting rod 355 fixedly connected to the transmission rod 353. The transmission rod 353 is vertically positioned relative to the drive block 354. The transmission rod 353 is horizontally positioned and rotatably connected to the support base 31. The end of the transmission rod 353 away from the drive block 354 is fixedly connected to the connecting block 352. The transmission rod 353 is vertically positioned relative to the connecting block 352. The side of the connecting block 352 away from the transmission rod 353 is fixedly connected to the top rod 351. The top rod 351 is horizontally positioned, with one end of the top rod 351 abutting against one side of the contact plate 33. The side of the contact plate 33 away from the top rod 351 is fixedly connected to the push rod 32. The two push rods 32 are horizontally positioned on both sides of the groove 121. The push rods 32 are slidably connected to the support base 31. The side of the contact plate 33 away from the top rod 351 is fixedly connected to the return spring 34. The return spring 34 is horizontally positioned, with one end of the return spring 34 away from the contact plate 33 fixedly connected to the support base 31.

[0038] Reference Figure 1 and Figure 4When the steel back is conveyed to the groove 121, it is not easy for the steel back to be precisely engaged in the groove 121 of the turntable 12. Fine-tuning of the steel back's position is required. The drive motor 363 is started, and its output shaft drives the rotating rod 362 to rotate. The rotating rod 362 drives the two cams 361 to rotate. When the protruding part of one of the cams 361 abuts against the lifting rod 355, the lifting rod 355 rises, causing one end of the driving block 354 to swing, thereby driving the transmission rod 353 to rotate. The moving rod 353 drives the connecting block 352 to swing, which in turn drives the top rod 351 to swing. The top rod 351 then drives the contact plate 33 to move laterally, which in turn drives the push rod 32 to move laterally. The push rod 32 gently pushes the steel back to fine-tune its position, ensuring the steel back is precisely engaged in the groove 121 of the turntable 12. The turntable 12 rotates, transporting the steel back to the drilling mechanism 4 for drilling. This improves the accuracy of the drilling position, reduces errors, and enhances product quality. The rotating rod 362 continues to rotate. After the lifting rod 355 separates from the protruding part of the cam 361, it lowers the lifting rod 355, causing the top rod 351 to reset. At this point, the reset spring 34 rebounds, causing the contact plate 33 to reset, and simultaneously the push rod 32 to reset. This facilitates subsequent fine-tuning of the positions of different steel backs. When the rotating rod 362 rotates 180 degrees, the protruding part of the other cam 361 abuts against the lifting rod 355, thereby realizing the alternating fine adjustment of the left and right sides of the steel back.

[0039] Reference Figure 1 , Figure 4 and Figure 5 A fixed seat 37 is provided below the support base 31. A hinge seat 371 is provided on the upper end surface of the fixed seat 37. The hinge seat 371 is horizontally arranged and fixedly connected to the lower ends of the two support bases 31. The side of the hinge seat 371 away from the base 11 is hinged to the fixed seat 37. A lifting block 372 is slidably connected to the lower end surface of the hinge seat 371. The lifting block 372 is slidably connected to the fixed seat 37. The lifting block 372 is located on the side of the hinge seat 371 close to the base 11. A drive rack 373 is fixedly connected to one side of the lifting block 372. The drive rack 373 is vertically arranged and meshes with a drive gear 374. A drive gear 374 is coaxially fixedly connected to a linkage rod 375, which is horizontally positioned. A rotating motor 376 is fixedly connected to a fixed base 37. The output shaft of the rotating motor 376 is coaxially fixedly connected to the linkage rod 375. The end of the linkage rod 375 away from the drive gear 374 is connected to a drive vertical rod 377 via a bevel gear pair. The drive vertical rod 377 is rotatably connected to the support frame 24 and is vertically positioned. The drive vertical rod 377 is connected to a rotating screw 25 via a bevel gear pair and is located inside the support frame 24. The support frame 24 is fixedly connected to the upper surface of the fixed base 37.

[0040] Reference Figure 1 , Figure 4 and Figure 5 The fixed seat 37 supports the support frame 24. When the steel back needs to be conveyed, the rotating motor 376 is started. The rotating motor 376 drives the linkage rod 375 to rotate. The linkage rod 375 drives the drive vertical rod 377 to rotate through the bevel gear pair. The drive vertical rod 377 drives the rotating screw 25 to rotate through the bevel gear pair, thereby realizing the conveying of the steel back. During the rotation of the linkage rod 375, the drive gear 374 drives the drive rack 373 to descend. The drive rack 373 drives the lifting block 372 to descend, thereby causing the hinge seat 371 to swing. When the lifting block 372 descends to the lowest point, it drives the upper end of the support seat 31 to approach the turntable 12, causing the push rod 32 to move to both sides of the groove 121. At this time, the steel back is conveyed above the groove 121. The push rod 32 is in position while conveying the steel back, which helps to improve processing efficiency. After the steel back is fine-tuned, the output shaft of the rotating motor 376 rotates in the opposite direction, which in turn drives the lifting block 372 to rise. The lifting block 372 drives the hinge seat 371 to swing, which in turn drives the support seat 31 to move obliquely upward, so that the push rod 32 moves away from the turntable 12, which makes it easier for the steel back to rotate to the drilling mechanism 4, and helps to reduce the phenomenon of the push rod 32 blocking the rotation of the steel back.

[0041] Reference Figure 1 The drilling mechanism 4 includes a drilling machine 41 and an electric slide rail 42. The electric slide rail 42 is arranged along the diameter of the turntable 12 and is slidably connected to the drilling machine 41. The electric slide rail 42 is horizontally arranged on the upper surface of the base 11. When the steel back rotates to the drilling machine 41 via the turntable 12, the electric slide rail 42 is activated, and the electric slide rail 42 drives the drilling machine 41 to move laterally to the steel back to drill holes in the pressed steel back.

[0042] Reference Figure 1 and Figure 2 The feeding mechanism 5 includes a push plate 51, a push cylinder 52, and a slide plate 53. The push plate 51 is horizontally positioned. The push cylinder 52 is fixedly connected to the connecting plate 16 and is positioned along the diameter of the turntable 12. The piston rod of the push cylinder 52 is fixedly connected to the push plate 51. The slide plate 53 is fixedly connected to the base 11 and is inclined. After the steel back is drilled, the turntable 12 transports the steel back to the slide plate 53. The push cylinder 52 is activated, and its piston rod extends, causing the push plate 51 to move laterally. The push plate 51 pushes the steel back onto the slide plate 53, thus facilitating the collection of the steel back.

[0043] The implementation principle of the fully automatic drilling equipment for brake pad steel backing in this application embodiment is as follows: When drilling is required on the steel backing, the piston rod of the lifting cylinder 22 extends, causing the electromagnetic chuck 21 to descend. The electromagnetic chuck 21 adsorbs the steel backing on the placement plate 26. The piston rod of the lifting cylinder 22 retracts, and the electromagnetic chuck 21 causes the steel backing to rise. Then, the rotating motor 376 is started, and the rotating motor 376 drives the linkage rod 375 to rotate. The linkage rod 375 drives the drive vertical rod 377 to rotate through the bevel gear pair. The drive vertical rod 377 drives the rotating screw 25 to rotate through the bevel gear pair, thus transversely conveying the steel backing.

[0044] During the rotation of the linkage rod 375, the drive gear 374 is driven to rotate. The drive gear 374 drives the drive rack 373 to descend. The drive rack 373 drives the lifting block 372 to descend, which in turn causes the fixed seat 37 to swing. When the lifting block 372 descends to the lowest point, it drives the upper end of the support seat 31 to approach the turntable 12, causing the push rod 32 to move to both sides of the groove 121. Then, the lifting cylinder 22 is activated to drive the electromagnetic chuck 21 to descend. The electromagnetic chuck 21 is de-energized, and the steel back is then transported to the groove 121.

[0045] Start the drive motor 363. The output shaft of the drive motor 363 drives the rotating rod 362 to rotate. The rotating rod 362 drives the two cams 361 to rotate. When the protruding part of one of the cams 361 abuts against the lifting rod 355, the lifting rod 355 rises, causing one end of the driving block 354 to swing, which in turn drives the transmission rod 353 to rotate. The transmission rod 353 drives the connecting block 352 to swing, and the connecting block 352 drives the push rod 351 to swing. The push rod 351 then drives the contact plate 33 to move laterally, and the contact plate 33 drives the push rod 32 to move laterally. The push rod 32 gently pushes the steel back to make a fine adjustment to the position of the steel back. When the rotating rod 362 rotates 180 degrees, the protruding part of the other cam 361 abuts against the lifting rod 355, thus alternately making fine adjustments to the left and right sides of the steel back.

[0046] After the steel back is fine-tuned, the output shaft of the rotating motor 376 rotates in the opposite direction, thereby driving the lifting block 372 to rise. The lifting block 372 drives the fixed seat 37 to swing, thereby driving the support seat 31 to move obliquely upward, so that the push rod 32 moves away from the turntable 12. Then the transmission motor 15 is started. The output shaft of the transmission motor 15 drives the transmission gear 14 to rotate. The transmission gear 14 drives the gear ring 13 to rotate, and then the gear ring 13 drives the turntable 12 to rotate to the drilling machine 41. At this time, the clamping cylinder 17 is started. The piston rod of the clamping cylinder 17 extends, driving the pressure plate 18 to clamp the steel back. Then the electric slide rail 42 is started. The electric slide rail 42 drives the drilling machine 41 to move laterally to the steel back to drill holes in the clamped steel back. After the steel back is drilled, the turntable 12 transports the steel back to the slide plate 53. The push cylinder 52 is started. The piston rod of the push cylinder 52 extends, driving the push plate 51 to move laterally. The push plate 51 pushes the steel back onto the slide plate 53.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
