[0002] The core function of the automatic adjusting arm is to automatically or manually adjust the gap between the brake pads and the brake drum to ensure the safety and reliability of the braking system. By maintaining a constant brake gap and optimizing the braking torque, it avoids brake failure, extends component life, and improves driving safety.

[0003] In related technologies, the automatic adjusting arm requires drilling several small holes on the outer circle of its main shaft hole during processing. The traditional process is to use a drilling machine for processing, but the drilling machine has low processing efficiency and cannot guarantee the processing quality. Using a machining center for drilling can improve efficiency and quality. Although the processing efficiency of the machining center is higher than that of the traditional drilling machine, the efficiency of processing only one piece at a time is still low. In addition, the existing fixtures have poor adaptability when clamping automatic adjusting arms of different sizes, which greatly affects the processing efficiency.

Four sliding grooves are opened on the top of the machining table 1. Platform sliders 5 are slidably installed on the bottom inner walls of the four sliding grooves. Each of the four platform sliders 5 is provided with a clamping mechanism on its top, and the four clamping mechanisms clamp the corresponding automatic adjusting arms 3 respectively.

[0034] In this embodiment, four positioning bases 2 are fixedly installed on the top of the processing table 1, and four automatic adjustment arms 3 respectively abut against the corresponding positioning bases 2. The positioning bases 2 can perform preliminary positioning of the automatic adjustment arms 3.

[0035] In this embodiment, ball screws 4 are rotatably installed on one inner wall of each of the four sliding grooves, and the four platform sliders 5 are respectively threaded onto the corresponding ball screws 4, so that the platform sliders 5 can be moved by the ball screws 4.

[0036] In this embodiment, the processing table 1 has four motor slots inside, and servo motors 6 are fixedly installed on the inner side of each of the four motor slots. The output shafts of the four servo motors 6 are fixedly connected to the corresponding ball screws 4. The outer sides of the four ball screws 4 are covered with telescopic rubber dust covers 7, which can prevent impurities from affecting the ball screws 4.

[0037] In this embodiment, each of the four inner support shells 16 has four support openings at its top. The four support openings on the same inner support shell 16 are connected. Inner support metal blocks 19 are slidably installed on the inner side of each of the multiple support openings. The four support metal blocks 19 can support and clamp the inner side of the automatic adjustment arm 3.

[0038] In this embodiment, threaded rods 17 are rotatably installed on the inner sides of the four inner support shells 16. The top ends of the four threaded rods 17 extend out of the corresponding inner support shells 16. The top ends of the four threaded rods 17 are provided with flat grooves. Workers can use a screwdriver to rotate the threaded rods 17 through the flat grooves.

[0039] In this embodiment, the outer sides of the four threaded rods 17 are all threaded with cross sliders 18, and the four cross sliders 18 are provided with linkage protrusions around their perimeter. The sides of the multiple inner support metal blocks 19 are provided with linkage grooves, and the multiple linkage protrusions are respectively adapted to the corresponding linkage grooves. The four inner support metal blocks 19 can be moved by the cross sliders 18.

[0040] In this embodiment, the clamping mechanism includes a fixed base 8, a contact metal block 9, two fixed posts 10, two flipping arms 11, and a crank assembly. The fixed base 8 is fixedly installed on the top of the platform slider 5. The contact metal block 9 is fixedly installed on one side of the fixed base 8. The contact metal block 9 abuts against the automatic adjustment arm 3. Two fixed posts 10 are fixedly installed on the inner side of the fixed base 8. The flipping arms 11 are rotatably sleeved on the outer side of the two fixed posts 10. The two flipping arms 11 clamp the same automatic adjustment arm 3. The same crank assembly is provided on one side of the two flipping arms 11. By cooperating with the contact metal block 9 and the positioning base 2, the automatic adjustment arm 3 can be better positioned.

[0041] In this embodiment, a cylinder 12 is fixedly installed on the other side of the fixed base 8, and a movable base 13 is fixedly installed on the piston end of the cylinder 12. The movable base 13 is slidably installed on the top of the platform slider 5, and the cylinder 12 can drive the movable base 13 to move.

[0042] In this embodiment, the crank assembly includes two movable columns 14 and two cranks 15. Two movable columns 14 are fixedly installed on the inner side of the movable base 13. Cranks 15 are rotatably sleeved on both movable columns 14. The two cranks 15 are respectively hinged to the corresponding flipping arms 11, and the flipping arms 11 can be flipped by the cranks 15.

[0043] Working principle: When drilling holes in the automatic adjusting arm 3, the operator places the automatic adjusting arm 3 on the processing table 1, making it contact the positioning base 2, and simultaneously positioning the inner support shell 16 inside the automatic adjusting arm 3. Then, a screwdriver is used to rotate the threaded rod 17, on which a cross slider 18 is threaded. The cross slider 18 has linkage protrusions around its circumference. The top of the inner support shell 16 has four support openings, and inner support metal blocks 19 are slidably installed inside each of the four support openings. Each of the four inner support metal blocks 19 has a linkage groove on one side, and the four linkage protrusions are respectively matched with their corresponding linkage grooves. Therefore, the cross slider 18 cannot rotate with the threaded rod 17. The rotation of the threaded rod 17 drives the cross slider 18 to move axially. The upward movement of the cross slider 18 presses against the four inner support metal blocks 19, causing the four inner support metal blocks 19 to move radially. The four inner support metal blocks 19 then press against the inner support of the automatic adjusting arm 3. The wall is internally supported and clamped to complete the initial fixation. Then, the servo motor 6 is started. The servo motor 6 drives the ball screw 4 to rotate, which in turn drives the platform slider 5 to move. The platform slider 5 moves, which drives the clamping mechanism to move. The contact metal block 9 moves and contacts the automatic adjusting arm 3, which cooperates with the positioning base 2 to position the automatic adjusting arm 3. At the same time, the cylinder 12 is started. The cylinder 12 retracts and drives the moving base 13 to move. The moving base 13 moves the two moving columns 14, which in turn drive the corresponding cranks 15 to move. The two cranks 15 move and drive the corresponding flipping arms 11 to move. The two flipping arms 11 are respectively rotated and sleeved on the corresponding fixed columns 10. Therefore, the two flipping arms 11 can only rotate around the corresponding fixed columns 10 as the center. The two flipping arms 11 flip and clamp the automatic adjusting arm 3, completing the positioning and clamping of the automatic adjusting arm 3. After repeating the above steps to install the other three automatic adjusting arms 3, drilling can be performed.

[0044] The technological advancements of this invention compared to existing technologies are: it can clamp and limit the automatic adjusting arms 3 of different sizes, improving the adaptability of the equipment; and it can clamp four automatic adjusting arms 3 at a time, allowing the machining center to process four automatic adjusting arms 3 simultaneously, greatly improving processing efficiency and increasing the practicality of the equipment.
