Description

Technical Field

[0001] The utility model relates to the technical field of brake disc processing, in particular to a fixture for brake disc processing. Background Technique

[0002] The brake disc is a friction pair of a disc brake. In addition to having the strength and stiffness required as a component, it should also have as high and stable a friction coefficient as possible, as well as appropriate wear resistance, heat resistance, heat dissipation, and heat capacity, etc. When the brake disc is processed, a fixture is usually required to fix the brake disc.

[0003] For example, a brake disc processing fixture with the publication number of "CN218744875U". The first support part can provide enough clamping area compared with the brake disc, so there is no need to consider the problem of clamping deviation. One clamping is completed, which improves the work efficiency. However, when this brake disc processing fixture limits the position of the brake disc, the operator needs to rotate the brake disc multiple times to make the through hole correspond to the threaded hole, which consumes a lot of physical strength of the operator, thus increasing the manual labor. At the same time, this brake disc processing fixture requires the operator to rotate multiple bolts to fix the brake disc, and the time required to rotate multiple bolts is relatively long, thus reducing the work efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when limiting the position of the brake disc, the operator needs to rotate the brake disc multiple times to make the through hole correspond to the threaded hole, which consumes a lot of physical strength of the operator, thus increasing the manual labor. At the same time, this brake disc processing fixture requires the operator to rotate multiple bolts to fix the brake disc, and the time required to rotate multiple bolts is relatively long, thus reducing the work efficiency, and a fixture for brake disc processing is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] Design a fixture for brake disc processing, including a brake disc. A limiting mechanism is arranged inside the brake disc. An auxiliary fixing mechanism is arranged on the left side below the limiting mechanism. The inner wall of the brake disc abuts against the top block;

[0007] The limiting mechanism includes a first outer shell. The inner wall of the first outer shell is threadedly connected with a threaded rod. The right end of the threaded rod is rotationally connected with a slider through a bearing. The outer wall of the slider is slidably connected with two limiting plates. The left sides of the limiting plates are fixedly connected to the first outer shell.

[0008] Preferably, the inner walls of the sliders are all slidably connected with sliding rods. The outer walls of the sliding rods are slidably connected with the first outer shell and fixed blocks.

[0009] Preferably, a plurality of springs are provided inside the first housing. Both ends of the springs are fixedly connected to the slide rod and the fixed block respectively, and the outer walls of the fixed blocks are fixedly connected to the first housing.

[0010] Preferably, the auxiliary fixing mechanism includes a clamping block. A plurality of clamping grooves are machined on the clamping block. The clamping block is slidably connected to the support block through the clamping grooves. A support rod is slidably connected to the right end of the support block, and the upper end of the support rod is in contact with the brake disc.

[0011] Preferably, the upper end of the clamping block is fixedly connected to the first housing.

[0012] For a fixture for machining a brake disc proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the clamping block and the auxiliary fixing mechanism, select appropriate support blocks and support rods according to the size of the brake disc, align the axis of the brake disc with the axis of the first housing, insert the support block into the clamping block along the clamping groove, and then the operator places the brake disc on the support rod, so that when fixing the brake disc, it is not necessary for the operator to rotate the brake disc multiple times, and it is not necessary for the operator to always hold the brake disc by hand, thus saving labor.

[0013] Through the cooperation of the top block and the limiting mechanism, when the threaded rod rotates forward, it drives the slider to move, thereby driving a plurality of slide rods to slide synchronously outward along the inclined grooves machined on the slider. The movement of the slide rod drives the top block to move, so that when fixing the brake disc, only by the operator rotating one screw rod can drive a plurality of top blocks to move outward synchronously. Compared with the operator rotating a plurality of bolts, the time required is shorter, thus improving the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present utility model will be further described below in conjunction with the attached drawings:

[0021] Refer to the attached Figures 1-5 In this embodiment, a fixture for processing a brake disc includes a brake disc 1. A limiting mechanism 2 is arranged inside the brake disc 1. An auxiliary fixing mechanism 5 is arranged on the left side below the limiting mechanism 2. The inner wall of the brake disc 1 abuts against the top block 3.

[0022] The limiting mechanism 2 includes a first outer shell 201. The inner wall of the first outer shell 201 is threadedly connected with a threaded rod 202. The right end of the threaded rod 202 is rotatably connected with a slide block 203 through a bearing. The outer wall of the slide block 203 is slidably connected with two limiting plates 206. The limiting plates 206 can limit the slide block 203. The left sides of the limiting plates 206 are fixedly connected with the first outer shell 201.

[0023] The inner walls of the slide blocks 203 are slidably connected with slide rods 204. The outer walls of the slide rods 204 are slidably connected with the first outer shell 201 and fixed blocks 205. A plurality of springs 4 are arranged inside the first outer shell 201. The elastic coefficient of the springs 4 is selected according to actual needs to meet the working requirements. The two ends of the springs 4 are fixedly connected with the slide rods 204 and the fixed blocks 205 respectively. The outer walls of the fixed blocks 205 are fixedly connected with the first outer shell 201.

[0024] The auxiliary fixing mechanism 5 includes a clamping block 501. A plurality of card slots 504 are processed on the clamping block 501. The clamping block 501 is slidably connected with a support block 502 through the card slots 504. A support rod 503 is slidably connected to the right end of the support block 502. The upper end of the support rod 503 abuts against the brake disc 1. The upper end of the clamping block 501 is fixedly connected with the first outer shell 201.

[0025] Working principle:

[0026] When using the fixture to fix the brake disc:

[0027] Brake disc fixing process:

[0028] The operator first selects appropriate support blocks 502 and support rods 503 according to the size of the brake disc 1, aligns the axis of the brake disc 1 with the axis of the first outer shell 201, inserts the support block 502 into the clamping block 501 along the card slot 504, and then the operator places the brake disc 1 on the support rod 503.

[0029] Then the operator rotates the threaded rod 202. The forward rotation of the threaded rod 202 drives the slider 203 to move, thereby driving a plurality of sliding rods 204 to slide outwards synchronously along the inclined grooves machined on the slider 203. The movement of the sliding rod 204 drives the top block 3 to move. When the outer wall of the top block 3 is in close contact with the inner wall of the brake disc 1, stop rotating the threaded rod 203. When fixing the brake disc 1, it is not necessary for the operator to rotate the brake disc 1 multiple times and can be directly fixed. At the same time, only by rotating one threaded rod 202, a plurality of top blocks 3 can be driven to move synchronously, which takes less time compared to the operator rotating multiple bolts to fix the brake disc, thus improving work efficiency. When it is necessary to disassemble the brake disc 1, the operator only needs to reverse the threaded rod 202, and through the elastic force of the spring 4, the plurality of top blocks 3 can be reset. Then the operator first removes the support block 502, then takes away the support rod 503, and then inserts the right end of the second housing 201 into the three-jaw chuck of the lathe to machine the brake disc 1.

[0030] Although the present invention has been illustrated and described with reference to the preferred embodiments, those skilled in the art should understand that various changes in form and details may be made within the scope of the claims.
