Description

Technical Field

[0001] This utility model belongs to the field of positioning tooling technology, and in particular relates to a positioning tooling for milling brake calipers. Background Technology

[0002] The automotive brake caliper milling positioning fixture is a specialized jig used to fix and position brake calipers. Its core function is to ensure the precise position and stability of the brake caliper during milling. It restricts the workpiece's degrees of freedom through a main reference (such as a mating surface or mounting hole) and locating pins (cylindrical pins and diamond pins), preventing displacement or deflection. The clamping device (hydraulic, pneumatic, or manual) applies force evenly to fix the workpiece, avoiding machining vibration or deformation. The fixture is typically made of high-rigidity steel, structurally designed to avoid toolpaths and include coolant chip removal channels.

[0003] When calipers are milled on machine tools, most of them use manual positioning fixtures. The current method is to set up multiple positioning blocks with multiple degrees of freedom on the base, and then complete the final positioning through multiple manual clamping mechanisms. The traditional manual clamping mechanism works by using threads to achieve clamping and loosening. After the threads are loosened, the pressure plate is rotated to avoid the workpiece picking and placing path. However, the ease of operation of this method needs to be improved, and the rotation required is relatively large. It will cause interference during the clamping process of some calipers, and the flexibility and compatibility are not good.

[0004] To address the aforementioned issues, this application proposes a milling and positioning fixture for brake calipers. Utility Model Content

[0005] The purpose of this utility model is to provide a milling and positioning fixture for brake calipers, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a milling and positioning fixture for a brake caliper, comprising an adapter mounted on a mounting base, a support platform for limiting the caliper body at the front end of the adapter, a rectangular positioning pin on the support platform that is adapted to insert into the caliper body, a plurality of support blocks for supporting the caliper body fixedly mounted on the support platform, and a positioning rod for limiting the caliper body on the side of the support platform, and further comprising:

[0008] A clamping component is mounted on an adapter and two sets are arranged symmetrically with respect to the support platform. The clamping component includes a guide rod and a support rod connected to the mounting base, and a pressure plate that is movably connected to the guide rod and the support rod in the axial and radial directions.

[0009] Furthermore, the guide rod and support rod are threadedly connected to the adapter seat and tightened by a fixing nut, and the guide rod and support rod are arranged in parallel and distributed perpendicularly to the pressure plate.

[0010] Furthermore, a sliding linkage plate is provided on the outside of the pressure plate, and the linkage plate has a movable hole that fits onto the outside of the support rod and the clamping screw.

[0011] Furthermore, a clamping nut is rotatably connected to the upper end of the linkage plate, and the clamping nut is also threadedly connected to the clamping screw. The clamping plate clamps the clamp body through the thread between the clamping nut and the clamping screw.

[0012] Furthermore, the pressure plate has a clamping hole that is axially inserted into the guide rod and the support rod. The pressure plate also has a first sliding groove that communicates with the clamping hole and is used for the movement of the clamping screw. The pressure plate also has a second sliding groove for the guide rod and the support rod to slide radially.

[0013] Furthermore, a limiting block is welded to the end of the clamping screw away from the support rod, and the diameter of the limiting block is larger than that of the clamping screw.

[0014] Furthermore, the linkage plate is arranged in a "C" shape.

[0015] This utility model has the following beneficial effects:

[0016] This utility model can position the clamp body before clamping by setting a positioning pin, a support block, and a positioning rod. The support block also serves as a support when the clamp body is clamped, ensuring the positioning reliability of the clamp body.

[0017] The pressure plate of this utility model can slide on the guide rod and support rod. When the pressure plate slides to the side, it can leave enough space for the clamp body to be picked up and put down, and the operation is more convenient. Compared with the traditional rotary structure, it has the advantages of convenient operation and better flexibility.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-5As shown, this utility model is a milling positioning fixture for a brake caliper, including an adapter 2 mounted on a mounting base 1. The front end of the adapter 2 is provided with a support platform 3 for limiting the caliper body 5. The support platform 3 serves to raise the caliper body 5, increasing the distance between the caliper body 5 and the adapter 2, thereby providing sufficient space for the milling cutter to move. The support platform 3 is provided with a rectangular positioning pin 31 that is compatible with the caliper body 5. The positioning pin 31 can limit the horizontal level in four directions (up, down, left, and right) and also serves to prevent rotation, ensuring the positioning accuracy of the caliper body 5. Several support blocks 32 are fixedly provided on the support platform 3 to support the caliper body 5. Each support block 32 supports the caliper body 5 at different positions and at different heights, ensuring that the milling position of the caliper body 5 is precisely matched with the milling cutter. The side of the support platform 3 is provided with a positioning rod 33 that limits the caliper body 5. The positioning rod 33 limits the caliper body 5 from the outside.

[0030] The clamping component 4 is mounted on the adapter 2 and is arranged in two sets symmetrically with respect to the support platform 3. The clamping component 4 includes a guide rod 41 and a support rod 42 connected to the mounting base 1, and a pressure plate 43 movably connected to the guide rod 41 and the support rod 42 along the axial and radial directions. The radial movement method requires less space than the rotation method, which means it is more flexible to use. The guide rod 41 and the support rod 42 are threaded to the adapter 2 and clamped and fixed by the fixing nut 46. The guide rod 41 and the support rod 42 are arranged in parallel and distributed perpendicularly to the pressure plate 43. The threaded arrangement of the guide rod 41 and the support rod 42 can adjust the pressure plate 43 to a suitable clamping position by the screw of the adapter 2. The fixing nut 46 plays a positioning role for the adjusted guide rod 41 and the support rod 42.

[0031] The pressure plate 43 is provided with a sliding linkage plate 44 on its outside. The linkage plate 44 has an active hole 441 that fits on the outside of the support rod 42 and the clamping screw 421. The linkage plate 44 can drive the pressure plate 43 to move simultaneously by the axial movement force after the clamping nut 45 is screwed on, without the need to push it a second time. Compared with the prior art, the operation is more convenient. The clamping screw 421 is welded and fixed to the support rod 42.

[0032] The upper end of the linkage plate 44 is rotatably connected to a clamping nut 45, and the clamping nut 45 is also threadedly connected to the clamping screw 421. The clamping plate 43 clamps the clamp body 5 through the thread of the clamping nut 45 and the clamping screw 421. The threaded clamping method is low in cost, reliable in structure, and can ensure the clamping stability.

[0033] The pressure plate 43 has a clamping hole 431 that is axially inserted into the guide rod 41 and the support rod 42. The pressure plate 43 also has a first sliding groove 432 that communicates with the clamping hole 431 and is used to clamp the screw 421. The pressure plate 43 also has a second sliding groove 433 for the guide rod 41 and the support rod 42 to slide radially. The movable cooperation between the pressure plate 43, the support rod 42, and the guide rod 41 ensures reliable clamping while being more flexible in use. It can also reduce the range of motion without changing the overall volume, so that it can cooperate more flexibly with the clamping of the clamp body 5.

[0034] Among them, a limiting block 422 is welded to the end of the clamping screw 421 away from the support rod 42. The diameter of the limiting block 422 is larger than that of the clamping screw 421. The limiting block 422 can prevent the clamping nut 45 from coming off, and at the same time, it can provide a positioning effect for the radial sliding between the pressure plate 43 and the guide rod 41 and the support rod 42, ensuring that the pressure plate 43 moves into place before sliding.

[0035] The linkage plate 44 is C-shaped, which ensures the axial linkage between the pressure plate 43 and the clamping nut 45 while facilitating installation and disassembly.

[0036] Understandably, the positioning system, consisting of positioning pins, support blocks, and positioning rods, pre-positions and provides support for the clamp body before clamping, ensuring reliable positioning. In conjunction with the pressure plate that can slide laterally along the guide rod and support rod, it can move laterally to create ample operating space when opening, making it easier to pick up and put down the clamp body. Compared with the traditional rotary structure, it has the advantages of flexible operation and higher efficiency.

[0037] One specific application of this embodiment is as follows: the fixing nut 46 is screwed into the outside of the guide rod 41 and the support rod 42, and one end of the guide rod 41 and the support rod 42 connected to the fixing nut 46 is threaded to the adapter 2. At the same time, the clamping height of the pressure plate 43 is adjusted. After the adjustment is completed, the fixing nut 46 is screwed in until it is pressed tightly against the support platform 3, and the guide rod 41 and the support rod 42 are locked. The overall installation state of the pressing component 4 is as follows. Figure 1-4 As shown;

[0038] Positioning of clamp body 5: as follows Figure 4The diagram shows the open state of the clamping component 4. At this time, the pressure plate 43 moves to the maximum extent to both sides, leaving space for the clamp body 5 to be placed in front of the support platform 3. The clamp body 5 is placed on the support platform 3, and the positioning pin 31 is inserted into the center of the clamp body 5 for positioning. Multiple positioning pins 31 support the clamp body 5 at different heights, and the symmetrical positioning rods 33 limit the clamp body 5 from the side. At this time, the clamp body 5 is positioned at the upper limit of the support platform 3. Then, the pressure plate 43 is slid horizontally so that the support rod 42 is coaxial with the clamping hole 431. During this sliding process, the pressure plate 43 also moves inside the linkage plate 44. Then, the clamping nut 45 is tightened. The clamping nut 45 drives the pressure plate 43 to move along the axial direction of the guide rod 41 and the support rod 42 through the linkage plate 44 until the front end of the pressure plate 43 presses down on the clamp body 5. The two sets of clamping components 4 are operated in sequence, and then the milling work is performed.

[0039] After processing, loosen the clamping nut 45. During the loosening process, the clamping nut 45 will drive the pressure plate 43 to move in the opposite direction along the axial direction outside the guide rod 41 and the support rod 42 under the action of the linkage plate 44. The guide rod 41 and the support rod 42 will disengage from the clamping hole 431. At this time, the horizontal sliding pressure plate 43 will slide the clamping screw 421 to the bottom along the first slide groove 432, and the support rod 42 will slide to the bottom along the second slide groove 433. Remove the clamp body 5.
