Description

Technical Field

[0001] This utility model relates to the field of fan-shaped hinge handle processing technology, specifically a fan-shaped hinge handle processing tooling. Background Technology

[0002] In the field of machining, the sector-shaped hinge handle is a key component and is widely used in automation equipment, precision instruments and aerospace. Its machining accuracy directly affects the overall performance and service life of the equipment, thus placing extremely high demands on the clamping stability during the machining process.

[0003] Currently, traditional tooling for processing sector-shaped hinged handles mostly uses manual clamps or simple positioning structures. These toolings have obvious limitations. Manual clamps require operators to manually rotate the threaded rod for clamping, which is not only inefficient but also cumbersome. Multiple adjustments are required using tools such as wrenches and bolts, resulting in long clamping times and severely restricting production efficiency. Utility Model Content

Detailed Implementation

[0023] 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 protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a fan-shaped hinge handle processing fixture, including: a positioning device 1, with a hinge handle 2 slidably connected to the inner wall of the positioning device 1; the positioning device 1 includes a base 11, with a corner bracket 12 fixedly connected to the outer wall of the base 11, a placement groove 13 opened on the outer wall of the top of the base 11, and symmetrically opened sliding grooves 14 on the outer wall of the top of the base 11, with sliding columns 15 symmetrically fixedly connected to the inner wall of the sliding grooves 14, a fixing plate 16 slidably connected to the outer wall of the sliding columns 15, a pull handle 17 fixedly connected to the outer wall of the top of the fixing plate 16, a limiting plate 18 fixedly connected to the outer wall of the side of the fixing plate 16, a limiting groove 181 opened on the outer wall of the limiting plate 18, and pressure springs 19 symmetrically fixedly connected to the outer wall of the side of the fixing plate 16.

[0025] The outer wall of the bottom of the hinge handle 2 is slidably connected to the inner wall of the placement groove 13, and the outer wall of the fixing plate 16 is slidably connected to the outer wall of the hinge handle 2. The bottom of the hinge handle 2 is embedded into the placement groove 13 at the top of the base 11, and the hinge handle 2 is clamped and fixed by the positioning device 1.

[0026] The slide 14 is set on both sides of the placement slot 13, and the corner brackets 12 are arranged in an array along the four corners of the base 11. The base 11 is installed on the operating table through the corner brackets 12.

[0027] The outer wall of the pressure spring 19 away from the fixed plate 16 is fixedly connected to the inner wall of the slide groove 14, and the outer wall of the fixed plate 16 is slidably connected to the inner wall of the slide groove 14. When the pressure spring 19 releases its elastic potential energy, it will push the fixed plate 16 to slide along the slide column 15 towards the placement groove 13. At the same time, the fixed plates 16 on both sides slide against the outer wall of the hinge handle 2, firmly locking it in the placement groove 13.

[0028] The outer wall of the top of the base 11 is symmetrically provided with positioning grooves 191. The inner wall of the positioning grooves 191 is symmetrically fixedly connected with slide rods 192. The outer wall of the slide rods 192 is slidably connected with slide plates 193. The outer wall of the top of the slide plates 193 is fixedly connected with limit blocks 194 and buttons 195. The outer wall of the bottom of the slide plates 193 is symmetrically fixedly connected with compression springs 196.

[0029] The outer wall of the slide plate 193 is slidably connected to the inner wall of the positioning groove 191. The outer wall of the compression spring 196 on the side away from the slide plate 193 is fixedly connected to the inner wall of the positioning groove 191. The outer wall of the limiting block 194 is slidably connected to the inner wall of the limiting groove 181. The compression spring 196 pushes the slide plate 193 to move upward, and the limiting block 194 is embedded in the limiting groove 181, which can lock the fixing plate 16.

[0030] When in use, the bottom of the hinge handle 2 is embedded into the placement groove 13 on the top of the base 11, and the hinge handle 2 is clamped and fixed by the positioning device 1 to facilitate the installation of parts. The base 11 is installed on the operating table by the corner bracket 12.

[0031] When the hinge handle 2 is inserted into the placement groove 13, it is in a state of waiting to be fixed. At this time, the fixing plate 16 is slidably connected to the sliding groove 14 on both sides of the placement groove 13 through the sliding column 15. Under the push of the compression spring 196, the top of the limiting block 194 is inserted into the limiting groove 181 on the limiting plate 18, fixing the fixing plate 16 and preventing it from sliding. One end of the pressure spring 19 is fixed to the inner wall of the sliding groove 14, and the other end abuts against the fixing plate 16, and is in a compressed state.

[0032] When it is necessary to fix the hinge handle 2, press button 195 to drive the slide plate 193 to slide downward in the positioning groove 191. The slide rod 192 provides guidance for the slide plate 193. When the slide plate 193 moves down, it compresses the compression spring 196 at the bottom and drives the limit block 194 to disengage from the limit groove 181, releasing the lock on the fixing plate 16. After the limit is released, the pressure spring 19 releases its elastic potential energy and pushes the fixing plate 16 to slide along the slide column 15 towards the placement groove 13. The fixing plates 16 on both sides slide against the outer wall of the hinge handle 2 at the same time, firmly locking it in the placement groove 13 to achieve positioning and fixation. At this time, the hinge handle 2 can be installed with parts.

[0033] When it is necessary to remove the hinge handle 2, pull the handle 17 to drive the fixed plate 16 to slide outward of the slide groove 14 against the resistance of the pressure spring 19. At this time, the pressure spring 19 is compressed and accumulates elastic potential energy. The fixed plate 16 separates from the hinge handle 2 and releases the clamping state. When the fixed plate 16 slides to the initial position, the limiting groove 181 aligns with the limiting block 194. The compression spring 196 pushes the slide plate 193 upward. The limiting block 194 re-embeds into the limiting groove 181, locks the fixed plate 16 again, and returns to the initial state for easy use next time.
