Description

Technical Field

[0001] This utility model relates to the field of brake pad production, and in particular to a drilling device for brake pad production. Background Technology

[0002] In a car's braking system, brake pads are the most critical safety component. The effectiveness of braking depends entirely on the brake pads. To dissipate heat, holes need to be drilled on the surface of the brake pads during the manufacturing process.

[0003] Chinese Patent Publication No. CN213437298U discloses a drilling device for automotive brake pads, relating to the technical field of automotive parts processing equipment. This utility model includes a working plate, with a driving structure at its upper end. One end of the driving structure is slidably connected to a fixing mechanism. A fixed base plate is located at the lower end of the working plate, and a support frame is welded and fixed to the upper end of the fixed base plate. The working plate is connected and fixed to the fixed base plate via the support frame. A column is located at one end of the fixed base plate, and an extension rod is welded and fixed to one end of the upper end of the column. A drilling mechanism is located at the lower end of the extension rod, away from the column. The design of the fixing mechanism allows the device to quickly and conveniently fix brake pads of different models, reducing the time required for brake pad fixing and improving work efficiency. Furthermore, the design of the unloading structure allows the device to effectively unload processed brake pads, avoiding the injuries caused by manual unloading.

[0004] Existing drilling devices are inefficient, typically using only one drill bit, resulting in only one hole being drilled at a time. However, multiple holes are required for brake discs, significantly increasing workload, reducing efficiency, and hindering brake pad installation and removal. Generally, drilling devices use a screw and pressure plate to clamp and fix the brake pads, requiring repeated screw rotation for installation and removal, which is cumbersome, increases workload, reduces efficiency, and is inconvenient to use. To address these problems, we propose a drilling device for brake pad production. Utility Model Content

[0016] The present invention is further configured such that a turntable is fixedly sleeved at one end of the bidirectional lead screw.

[0017] By adopting the above technical solution, a turntable is set up to facilitate the rotation of the bidirectional lead screw.

Sliding blocks 4 are slidably connected to the inner walls of the sliding grooves 3. A lifting rod 5 is bolted between the two sliding blocks 4. A hydraulic rod 6 is bolted to the top of the lifting rod 5 and is also bolted to the top of the fixed frame 2. Two sliding grooves 7 are formed on the inner wall of the lifting rod 5, and sliding blocks 8 are slidably connected to the inner walls of the sliding grooves 7. A double-ended lead screw 9 is threaded between the inner walls of the sliding blocks 8, and the double-ended lead screw 9 is rotatably sleeved with the inner wall of the lifting rod 5. The sliding block 8 is rotatably connected to the inner wall of the left slider 4. A transmission block 10 is bolted to the surface of the sliding block 8, and a slide cylinder 11 is bolted to the surface of the transmission block 10. The slide cylinder 11 is slidably connected to the lifting rod 5. A drilling mechanism 12 is provided at the bottom of the slide cylinder 11. By setting two drill bits 21 to drill holes in the brake pad, the drilling efficiency can be achieved, reducing the workload and improving the work efficiency. By rotating the turntable 25, the bidirectional lead screw 9 drives the sliding block 8 to move. The movement of the sliding block 8 causes the slide cylinder 11 to drive the drill bits 21 to move, which can adjust the drilling spacing and improve practicality and applicability.

[0033] refer to Figure 2 The drilling mechanism 12 includes a fixed shell 19, the top of which is bolted to the bottom of the slide cylinder 11. A second motor 20 is bolted to the inner wall of the fixed shell 19. The output end of the second motor 20 extends to the outside of the fixed shell 19 and is fixedly connected to a drill bit 21 through a chuck. By setting the drilling mechanism 12, drilling is convenient.

[0034] refer to Figure 2A fixing block 22 is rotatably sleeved on the surface of the bidirectional lead screw 9, and the fixing block 22 is bolted to the surface of the slider 4. A fixing bolt 23 is threadedly connected to the inner wall of the fixing block 22, and the inner end of the fixing bolt 23 contacts the surface of the bidirectional lead screw 9. By setting the fixing block 22 and the fixing bolt 23, the bidirectional lead screw 9 is fixed to ensure stability and thus ensure drilling accuracy.

[0035] refer to Figure 1 The surface of the lifting rod 5 is printed with scale lines 24, which facilitates the adjustment of the spacing between drill bits 21.

[0036] refer to Figure 1 and Figure 2 One end of the bidirectional lead screw 9 is fixedly sleeved with a turntable 25. By setting the turntable 25, it is easy to rotate the bidirectional lead screw 9.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A first motor 13 is bolted to the bottom of the drilling platform 1. The output end of the first motor 13 passes through the drilling platform 1 and is bolted to a fixed base 14. A pressing rod 15 is slidably sleeved on the inner wall of the fixed base 14. A connecting rod 16 is hinged to the surface of the pressing rod 15. A snap connector 17 is hinged to the other end of the connecting rod 16. The snap connector 17 is slidably sleeved with the inner wall of the fixed base 14. A tension spring 18 is fixedly connected between the snap connector 17 and the inner wall of the fixed base 14 by a spring fixing member. By mounting the brake disc on the fixed base 14 and then pressing down on the brake pad, the snap connector 17 snaps into the brake pad under the action of the tension spring 18, thus fixing the brake pad. This method facilitates the installation and removal of the brake pad, reduces workload, improves installation and removal efficiency, and is convenient to use.

[0039] refer to Figure 1 and 2 A positioning rod 26 is bolted to the top of the fixing seat 14. By setting the positioning rod 26, it is easy to position and fix the brake pad and ensure the drilling accuracy.

[0040] refer to Figure 2 The inner wall of the bottom of the fixed base 14 is rotatably connected to a roller 27. By setting the roller 27, the fixed base 14 is supported and its stability is improved.

[0041] Brief description of the usage process: Install the brake pad on the fixed base 14. Then, the hydraulic rod 6 drives the lifting rod 5 to lower the drill bit 21. The second motor 20 drives the drill bit 21 to rotate and drill a hole in the brake pad. After drilling, the drill bit 21 rises. Then, the first motor 13 drives the fixed base 14 to rotate the brake pad and drill holes in other positions. After drilling is completed, the hydraulic rod 6 drives the drill bit 21 to return to its original position, and the brake pad can be removed. This achieves the purpose of drilling. Setting two drill bits 21 to drill holes in the brake pad simultaneously can achieve high drilling efficiency. Turntable 25 rotates, causing the double-acting lead screw 9 to rotate. The rotation of the double-acting lead screw 9 causes the sliding block 8 to move relative to or away from each other. The relative or opposite movement of the sliding block 8 causes the transmission block 10 to move relative to or away from each other. The relative or opposite movement of the transmission block 10 causes the slide cylinder 11 to move relative to or away from each other. The relative or opposite movement of the slide cylinder 11 causes the fixed shell 19 to cause the second motor 20 to drive the drill bit 21 to move relative to or away from each other. The relative or opposite movement of the drill bit 21 changes the distance between the two drill bits 21, thereby allowing the spacing of the drill holes to be adjusted as needed.

[0042] When installing brake pads, align the mounting holes on the brake pads with the positioning rods 26 on the mounting base 14. Then, insert the brake pads into the mounting base 14 and press them down firmly so that the snap-fit ​​connector 17 engages with the brake pads under the action of the tension spring 18, thus fixing them in place and completing the installation. When the drilling is complete, press the pressing rod 15 to move the connecting rod 16, causing the snap-fit ​​connector 17 to retract. The snap-fit ​​connector 17 retracts and disengages from the brake pads, allowing the brake pads to be removed from the mounting base 14, thus completing the disassembly and facilitating the installation and removal of brake pads.
