Description

Technical Field

[0001] This utility model relates to the field of angular displacement sensor manufacturing technology, and in particular to a tooling for forming the hook of an angular displacement sensor. Background Technology

[0002] Chinese patent document CN216065177U discloses a hook forming fixture for a reed assembly in an angular displacement sensor. The reed assembly includes interconnected brush wires and reeds. The hook forming fixture includes a lower mold and an upper mold. The upper surface of the lower mold is formed by a top plane and an inclined plane. The top plane has a strip groove, four pillars, and a hook forming groove. The strip groove and the hook forming groove intersect each other, and the intersection area is located within the area enclosed by the four pillars. A fixing member is provided on the inclined plane. A protruding strip is provided at the lower center of the upper mold. This invention can achieve precise hook forming of the end of the brush wire away from the reed, thereby ensuring the hook forming quality of the brush wire. It also facilitates automated processing, speeds up operation, improves processing quality and efficiency, and results in a high product qualification rate, good consistency, and effective positioning. Ultimately, it improves the resistance stability and lifespan of the reed assembly.

[0003] The aforementioned bending hook forming fixture for a reed assembly of an angular displacement sensor may require manual positioning and centering of the material during processing, which may result in misalignment between the material and the center of the processing mold, thereby reducing the production efficiency and accuracy of the angular displacement sensor hook.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a tooling for forming a hook of an angular displacement sensor, including a mounting plate 1 and a positioning and centering mechanism 3. Two sets of positioning and centering housings 4 are provided above the mounting plate 1, and an upper mold 12 is provided above the mounting plate 1. A mounting frame 2 is fixedly installed at the bottom of the mounting plate 1. The positioning and centering mechanism 3 is set on the mounting frame 2 and is used to automatically position the processed material.

[0024] The positioning and centering mechanism 3 includes a cylinder 301, a moving plate 302, a connecting rod 303, and a connecting plate 304. The cylinder 301 is fixedly installed at the bottom of the mounting frame 2. The output end of the cylinder 301 extends to the top of the mounting frame 2 and is fixedly installed with the moving plate 302. Two sets of connecting rods 303 are hinged to the top of the moving plate 302. One end of each set of connecting rods 303 is hinged to a connecting plate 304. The positioning and centering mechanism 3 can drive the two sets of positioning and centering housings 4 to automatically position and center the processed material, ensuring that the material is aligned with the center of the lower mold 6 and the upper mold 12, thereby improving the production efficiency and accuracy of the angular displacement sensor hook.

[0025] The rear sides of both sets of connecting plates 304 are fixedly connected to a set of positioning and centering housings 4.

[0026] Mounting bracket 2 10 is fixedly mounted on the top of mounting plate 1, and cylinder 2 11 is fixedly mounted on the top of mounting bracket 2 10. The output end of cylinder 2 11 extends to the bottom of mounting bracket 2 10 and is fixedly mounted with upper mold 12.

[0027] A lower mold 6 is fixedly installed on the top of the mounting plate 1. A set of mounting blocks 7 are fixedly installed on the front and rear sides of the lower mold 6. A set of threaded slots are opened on both sets of mounting blocks 7. Two sets of mounting holes are opened on the top of the mounting plate 1. A set of threaded rods 8 are threadedly connected to the top of both sets of mounting blocks 7. One end of each set of threaded rods 8 extends to the bottom of the mounting plate 1 through a set of mounting holes. Two sets of nuts 9 are threadedly connected to the outer wall of each set of threaded rods 8. During long-term processing and production, when the lower mold 6 wears out, the lower mold 6 can be disassembled to avoid the wear of the lower mold 6 causing problems such as deviation in the processing dimensions of the hook and surface roughness, thereby improving the product quality of the hook.

[0028] The top of the mounting plate 1 is provided with two sets of sliding grooves, and a set of sliders 5 are slidably installed in each of the two sets of sliding grooves. The top of each set of sliders 5 is fixedly connected to a set of positioning and centering housings 4.

[0029] Four sets of supports are fixedly installed on the bottom of the mounting plate 1.

[0030] Working principle: When work is required, the operator holds the material to be processed and places it above the lower mold 6. Cylinder 1 301 is activated, and its free end moves downward, causing the moving plate 302 to move downward. This causes the two sets of connecting rods 303 to move. Through the action of the sliding groove and the two sets of sliders 5, the two sets of connecting plates 304 drive the two sets of positioning and centering housings 4 to move laterally, thereby fixing the material between the two sets of positioning and centering housings 4 and aligning the material with the lower mold 6. Cylinder 2 11 is activated, and its free end drives the upper mold 12 downward. Through the cooperation of the lower mold 6, the material can be processed into a U-shaped hook. When the lower mold 6 has been working for a long time and wears out, by rotating the four sets of nuts 9, the two sets of nuts 9 on the two sets of threaded rods 8 can be removed, and then the two sets of threaded rods 8 can be removed, separating the lower mold 6 from the mounting plate 1 for easy replacement and maintenance.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
