Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a fixed tooling for automatic grinding of pneumatic calipers. Background Art

[0002] Pneumatic calipers are key components in the car's braking system, which can provide more stable and reliable braking force to ensure driving safety.

[0003] Calipers are generally produced using a casting process with various structural forms, and pneumatic calipers are a common type. The burrs on the surface of caliper castings cannot meet customer requirements. Manual grinding of burrs is labor-intensive, the on-site environment is harsh, and the efficiency is low, which cannot guarantee timely supply to the market. Therefore, some manufacturers use automated robotic arm equipment for grinding to solve the problems of different casting sizes, low production efficiency, high safety risks, and high costs caused by manual grinding; but the automatic grinding of robotic arms requires special tooling to fix the caliper castings. Some existing tooling uses clamping methods, and the caliper has an irregular contour shape, and the traditional clamping method is not convenient for positioning. Summary of the invention

[0004] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide a fixed tooling for automatic grinding of pneumatic calipers.

[0005] The specific scheme of the utility model is: a fixed tooling for automatic grinding of pneumatic calipers, including a support frame, a flat plate is provided on the top of the support frame, a mounting hole connected to the equipment is provided on the bottom of the support frame, four support blocks A are installed on the top of the flat plate, the four support blocks A are installed at four corners and respectively match the corresponding positions of the inner contour of the caliper, each support block A has a threaded hole at the bottom, which is connected to the flat plate by bolts, and waist-shaped holes are provided on the flat plate corresponding to the threaded holes of each support block A to fine-tune the relative position of the support block A.

[0006] Furthermore, a support block B is mounted on the flat plate, and the support block B is used to support the cylinder part of the caliper.

[0007] Furthermore, the support frame includes a base plate and two support plates, the base plate is provided with the mounting holes, and the two support plates are mounted on both sides of the base plate.

[0008] Furthermore, the support plate and the bottom plate are both provided with hollow weight-reducing holes.

[0009] Furthermore, a weight-reducing hole is provided in the middle of the plate.

[0010] Compared with the prior art, the utility model has the following advantages: 1. The inner contour of the caliper is supported and limited by a support block to fix the caliper, replacing the traditional clamp, and better cooperating with the automated robotic arm for grinding; the labor intensity is reduced and the grinding efficiency is improved; 2. By setting waist-shaped holes, each support block can be fine-tuned to adapt to the dimensional error of the casting and improve the adaptability of the tooling; 3. It replaces the traditional clamp and is more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] See also Figure 1-6 This embodiment is a fixed tooling for automatic grinding of pneumatic calipers, including a support frame, a flat plate 3 is provided on the top of the support frame, and a mounting hole connected to the equipment is provided at the bottom of the support frame. Four support blocks A5 are installed on the top of the flat plate 3. The four support blocks A5 are installed at the four corners and match the corresponding positions of the inner contour of the caliper respectively. A threaded hole is provided at the bottom of each support block A5, which is connected to the flat plate 3 by bolts. The flat plate 3 is provided with waist-shaped holes 6 at the threaded holes corresponding to each support block A5 to fine-tune the relative position of the support block A5. The length of the waist-shaped hole 6 is 5mm. In this embodiment, three threaded holes are provided at the bottom of each support block A5. The waist-shaped holes 6 corresponding to the two support blocks A5 near the cylinder hole are arranged horizontally, and the waist-shaped holes 6 corresponding to the two support blocks A5 near the tail end of the caliper are arranged longitudinally.

[0019] Furthermore, a support block B4 is mounted on the flat plate 3, and the support block B4 is used to support the cylinder part of the caliper.

[0020] Furthermore, the support frame includes a base plate 1 and two support plates 2 , the base plate 1 is provided with the mounting holes, and the two support plates 2 are mounted on both sides of the base plate 1 .

[0021] Furthermore, the support plate 2 and the bottom plate 1 are both provided with hollow weight-reducing holes.

[0022] Furthermore, a weight-reducing hole is provided in the middle of the plate 3 .

[0023] When the utility model is working, the whole tooling is first installed on the grinding equipment and fixed, and then the workpiece 7 is placed on the tooling in a set direction, so that the inner contour of the bottom surface of the workpiece 7 fits with the four support blocks A5, and the cylinder hole part contacts the support block B4, so that the workpiece 7 cannot shake on the 5 support blocks, so that fixation is achieved, and the casting is placed completely and stably on the tooling, and then the upper surface of the workpiece 7 is automatically ground by the automated robotic arm; after grinding, the workpiece 7 can be directly taken out upwards without the need for locking and unlocking operations, which is more convenient than traditional clamp operations.

[0024] When the workpiece 7 cannot be placed into the fixture due to an error, the workpiece 7 can be placed stably by adjusting the position of the corresponding support block A5.
