Description

Technical Field

[0001] This utility model relates to the field of brake disc processing technology, specifically to a chuck for brake disc processing. Background Technology

[0002] Brake calipers clamp the brake disc to generate braking force. When the brake pedal is pressed, it is the caliper that clamps the brake disc to slow down or stop the vehicle. Brake discs offer better braking performance and are easier to maintain than drum brakes. The brake disc is a core component of the automotive braking system, and its machining precision directly affects braking performance and safety. During machining, the brake disc must be stably clamped by calipers to ensure machining accuracy.

[0003] However, traditional chucks for clamping brake discs typically suffer from the following technical drawbacks: One-piece chucks offer limited clamping functionality, requiring the replacement of the entire chuck set to accommodate different parts of the workpiece, leading to low efficiency in brake disc machining. Separate chucks, often secured with bolts or threads, are prone to clamping misalignment during installation due to thread wear or loosening, affecting machining accuracy and even posing a risk of workpiece detachment. Furthermore, the clamping stability of the chucks is insufficient. Existing chucks offer poor efficiency and reliability in brake disc machining; this solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a chuck for brake disc machining. The dovetail blocks of the outer support chuck and the inner support chuck are respectively inserted into the dovetail grooves of boss one and boss two to support the outer support chuck and the inner support chuck. Then, the outer support chuck is positioned by the positioning groove. This not only allows for the clamping of different parts of the brake disc by changing the chuck, resulting in higher machining efficiency, but also provides a more stable and reliable clamping of the brake disc, meeting the needs of efficient and high-precision brake disc machining.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a chuck for processing brake discs, comprising a support block detachably connected to a chuck drive mechanism, an inner support chuck and an outer support chuck detachably disposed on the support block, the inner support chuck being used to support the inner side of the brake disc, the outer support chuck being used to clamp the outer side of the brake disc, the side portion of the support block being respectively provided with locking components for locking the outer support chuck and the inner support chuck, the side portion of the inner support chuck and the outer support chuck being provided with locking holes, and the locking components being detachably connected to the locking holes.

[0006] The top side of the bearing block is provided with a boss for supporting the external support chuck. The side of the boss is provided with a dovetail groove. The side of the external support chuck is provided with a dovetail block corresponding to the dovetail groove. The external support chuck is connected to the dovetail groove of the boss through the dovetail block. The top side of the bearing block is also provided with a positioning groove for accommodating the external support chuck. The locking component is used to lock the external support chuck in the positioning groove.

[0007] The side of the bearing block is provided with a through hole communicating with the locking hole. The locking assembly includes a pin movably disposed in the through hole. One end of the pin is detachably inserted into the locking hole, and the other end of the pin is provided with an operating knob.

[0008] A connecting ring is provided on the side of the pin, and a spring is sleeved on the outside of the pin. One end of the spring is connected to the connecting ring, and the other end of the spring is connected to the bearing block.

[0009] The side of the bearing block is provided with a positioning hole, and the side of the operating knob is provided with a positioning rod. The positioning rod is detachably inserted into the positioning hole. The end of the pin is provided with a wedge-shaped surface, and the wedge-shaped surface contacts the bottom edge of the outer support clamp.

[0010] The connecting ring is rotatably sleeved on the outside of the pin, and the side of the bearing block is provided with a second positioning hole. The positioning rod can be detachably inserted into the second positioning hole, and the depth of the second positioning hole is less than the depth of the first positioning hole.

[0011] The bearing block is provided with a second boss for supporting the inner support clamp.

[0012] The inner support chuck has the same structure as the outer support chuck. The inner support chuck is also provided with a dovetail block, and the second boss is provided with a dovetail groove.

The top side of the bearing block 1 is also provided with a positioning groove 12 for accommodating the external support chuck 2. The locking component 4 is used to lock the external support chuck 2 in the positioning groove 12.

[0028] The side of the support block 1 is provided with a through hole 13 communicating with the locking hole 21. The locking component 4 includes a pin 41 movably disposed in the through hole 13. One end of the pin 41 is detachably inserted into the locking hole 21, and the other end of the pin 41 is provided with an operating knob 42.

[0029] A connecting ring 43 is provided on the side of the pin 41, and a spring 44 is sleeved on the outside of the pin 41. One end of the spring 44 is connected to the connecting ring 43, and the other end of the spring 44 is connected to the bearing block 1.

[0030] The side of the bearing block 1 is provided with a positioning hole 14, and the side of the operating knob 42 is provided with a positioning rod 421. The positioning rod 421 is detachably inserted into the positioning hole 14. The end of the pin 41 is provided with a wedge-shaped surface 411, which contacts the bottom edge of the outer support clamp 2.

[0031] The connecting ring 43 is rotatably sleeved on the outside of the pin 41. The side of the bearing block 1 is provided with a positioning hole 2 15. The positioning rod 421 can be separably inserted into the positioning hole 2 15. The depth of the positioning hole 2 15 is less than the depth of the positioning hole 14.

[0032] The bearing block 1 is provided with a boss 2 16 for supporting the inner support clamp 3.

[0033] The inner support chuck 3 has the same structure as the outer support chuck 2. The inner support chuck 3 is also provided with a dovetail block 22, and the second boss 16 is provided with a dovetail groove 111. The inner support chuck 3 is inserted into the dovetail groove 111 of the second boss 16 through the dovetail block 22.

[0034] The side of the support block 1 is provided with a positioning mark 17, and the outside of the operating knob 42 is provided with a positioning mark 422 corresponding to the positioning mark 17.

[0035] The specific working process of this utility model:

[0036] In use, first install the three jaws on the jaw drive mechanism. When it is necessary to clamp and support the outer edge of the brake disc, first rotate the pull-out operation knob 42 to ensure that the positioning rod 421 of the locking component 4 is inserted into the positioning hole 14, with the wedge surface 411 facing upward. Hold the outer support chuck 2 and insert the dovetail block 22 of the outer support chuck 2 into the dovetail groove 111 of the bearing block 1 until the bottom of the outer support chuck 2 is inserted into the positioning groove 12. The edge of the outer support chuck 2 overcomes the elastic force of the spring 44 and presses the pin 41 completely into the through hole 13. When the outer support chuck 2 is completely in the positioning groove 12, the spring 44 pushes the pin 41 out and inserts it into the locking hole 21 of the outer support chuck 2 to lock the outer support chuck 2. Start the jaw drive mechanism, clamp the brake disc through the outer support chuck 2, and then process the brake disc. The dovetail blocks 22 of the outer support chuck 2 and the inner support chuck 3 are inserted into the dovetail grooves 111 of the first boss 11 and the second boss 16, respectively, to support the outer support chuck 2 and the inner support chuck 3. Then, the outer support chuck 2 is positioned by the positioning groove 12. This not only satisfies the clamping of different parts of the brake disc by changing the chuck, making the processing efficiency of the brake disc higher, but also makes the clamping of the brake disc more stable and reliable.

[0037] When it is necessary to disassemble the outer support chuck 2, hold the operating knob 42 outward to pull the positioning rod 421 out of the positioning hole 14, then rotate it until the positioning mark 17 and the positioning mark 2 422 correspond. Release the operating knob 42, and the positioning rod 421 is inserted into the positioning hole 2 15. Since the depth of the positioning hole 2 15 is less than the depth of the positioning hole 14, and the wedge surface 411 faces downward, the pin 41 retracts. At this time, you can hold the bearing block 1 with one hand and easily remove the outer support chuck 2 with the other. The outer support chuck 2 is locked by the detachable insertion of the pin 41 into the locking hole 21 of the locking assembly 4. The pin 41 is pressed by the spring 44, making the connection between the outer support chuck 2 and the bearing block 1 more stable and reliable. The pin 41 is separated from the bearing block 1 by operating the knob 42, making it easier for the outer support chuck 2 to be separated from the bearing block 1. The installation and removal of the outer support chuck 2 are more convenient and quick, improving the efficiency of brake disc processing.

[0038] Both the outer support chuck 2 and the inner support chuck 3 are detachable. When the chuck is damaged, only a single chuck needs to be replaced, without replacing the entire chuck. This saves on chuck wear and replacement time costs, thereby reducing the cost of brake disc processing.
