A wire drawing positioning fixture

Abstract

This utility model relates to the field of fixture technology and discloses a wire drawing positioning fixture, including a base. Several pairs of top seats are vertically slidably installed inside the base. Each pair of top seats has a ball bearing mounted on its top, which guides the workpiece's movement. A synchronization plate is fixedly installed at the bottom of each pair of top seats, and a guide block is mounted on the synchronization plate. The guide block has a ramp on its end face. Clamping plates that slide against each other are installed on the side walls of the base, and a push plate is installed at the bottom of the clamping plates. When placing the workpiece, the ball bearings significantly reduce the friction between the workpiece and the positioning table, allowing the workpiece to slide smoothly and be easily adjusted to the appropriate position without effort, significantly improving the convenience of workpiece clamping. Furthermore, when clamping the workpiece, pushing the push plate moves the top seats, causing the ball bearings to move downwards and be stored, eliminating the ball bearings' influence on the workpiece. This allows the clamping plates to tightly clamp the workpiece, ensuring the workpiece is stable and does not wobble during processing, thus improving processing accuracy and efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically, it relates to a positioning fixture for wire drawing processing. Background Technology

[0002] In the wire drawing process, positioning fixtures are important devices to ensure the machining accuracy and quality of workpieces.

[0003] Currently, existing wire drawing positioning fixtures typically adjust the position of a workpiece by placing it directly on the fixture's positioning surface and then manually or mechanically pushing it. However, because the bottom of the workpiece is in direct contact with the fixture's positioning surface during adjustment, friction can easily cause it to scrape against the fixture. For workpieces that have already undergone wire drawing or require precision wire drawing, this scraping can easily damage the surface texture, leading to a decrease in surface quality, affecting the product's aesthetics and performance, increasing the scrap rate, and raising production costs.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A wire drawing positioning fixture, including a base.

[0007] Several pairs of top seats are vertically slidably installed inside the base. Each pair of top seats has a ball bearing installed on its top. The ball bearing is used to guide the workpiece to slide. A synchronization plate is fixedly installed at the bottom of each pair of top seats. A guide block is installed on the synchronization plate. The end face of the guide block is provided with a slope.

[0008] The base sidewall is equipped with mutually sliding clamps, and a push plate is installed at the bottom of the clamps. The lower surface of the push plate is slidably connected to the surface of the synchronization plate, and the push plate slides along the slope to the guide block and then squeezes the ball bearings into the base.

[0009] In a preferred embodiment of this utility model, a base is bolted to the bottom of the base, and a pair of guide rails are mounted on the base, the guide rails being compatible with the wire drawing processing machine.

[0010] In a preferred embodiment of this utility model, a positioning platform is installed on the base, the balls are evenly arranged in the positioning platform, a positioning block is installed at the center of the positioning platform, and the outer side wall of the positioning block corresponds to the inner side wall of the clamping plate.

[0011] In a preferred embodiment of this utility model, a pair of parallel slide rails are provided on the base, the push plate moves through the slide rails and the side wall of the push plate is slidably connected to the slide rails, a slide rod is installed at the bottom of the push plate and the slide rod is adapted to the guide block, and an electric push rod is installed on the side wall of the push plate and the electric push rod is installed on the inner side wall of the base.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] When placing a workpiece, the ball bearings significantly reduce the friction between the workpiece and the positioning table, allowing the workpiece to slide smoothly and be easily adjusted to the appropriate position without effort, thus significantly improving the convenience of workpiece clamping.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0025] like Figures 1 to 5 As shown, a wire drawing positioning fixture includes a base 1.

[0026] Several pairs of top seats 12 are vertically slidably installed inside the base 1. Each pair of top seats 12 is equipped with a ball bearing 13 on its top. The ball bearing 13 is used to guide the workpiece to slide. This design can significantly reduce the frictional resistance when the workpiece is placed, avoid surface wear, and improve the processing yield. A synchronization plate 11 is fixedly installed at the bottom of each pair of top seats 12. A guide block 14 is installed on the synchronization plate 11. The end face of the guide block 14 is provided with a ramp 15.

[0027] A clamping plate 6 is installed on the side wall of the base 1, and a push plate 7 is installed at the bottom of the clamping plate 6. The lower surface of the push plate 7 is slidably connected to the surface of the synchronous plate 11. After sliding along the ramp 15 to the guide block 14, the push plate 7 squeezes the ball bearing 13 into the base 1. This structure realizes the linkage between the clamping action and the ball bearing storage, which not only simplifies the operation process, but also ensures that the workpiece is stable and without displacement during clamping, thereby improving the machining accuracy.

[0028] like Figures 1 to 5 As shown, in a specific embodiment, a base 3 is bolted to the bottom of the base 1, and a pair of guide rails 2 are mounted on the base 1. The guide rails 2 are compatible with the wire drawing processing machine.

[0029] like Figures 1 to 5 As shown, a positioning platform 4 is further installed on the base 1, with ball bearings 13 evenly distributed in the positioning platform 4. A positioning block 5 is installed at the center of the positioning platform 4, and the outer wall of the positioning block 5 corresponds to the inner wall of the clamping plate 6. This modular design facilitates quick installation and disassembly of the fixture, significantly shortens equipment debugging time, improves processing efficiency, and reduces labor costs.

[0030] like Figures 1 to 5As shown, furthermore, a pair of parallel slide rails 8 are provided on the base 1, and a push plate 7 movably passes through the slide rails 8. The side wall of the push plate 7 is slidably connected to the slide rails 8. A slide rod 9 is installed at the bottom of the push plate 7, and the slide rod 9 is adapted to the guide block 14. An electric push rod 10 is installed on the side wall of the push plate 7, and the electric push rod 10 is installed on the inner side wall of the base 1. The precise positioning structure can ensure that the workpiece is clamped in the same position every time, effectively reducing the scrap rate caused by positioning errors and ensuring the stability of batch processing.

[0031] like Figures 1 to 5 As shown, a sliding plate 16 is further installed on the side wall of the synchronization plate 11. A limit rod 18 is slidably arranged on the sliding plate 16. A limit seat 17 is installed on the top of the limit rod 18, and the limit seat 17 is installed on the base 1. A limit plate 19 for disengaging is installed on the top of the limit rod 18.

[0032] like Figures 1 to 5 As shown, a limiting spring 20 is further sleeved on the side wall of the limiting rod 18. One end of the limiting spring 20 is engaged with the bottom of the slide plate 16, and the other end is engaged with the limiting seat 17. The combination of the limiting spring and the elastic return spring 20 not only ensures the safety of the fixture operation, but also reduces the wear of mechanical parts, extends the service life of the fixture, and reduces maintenance costs.

[0033] The implementation principle of a wire drawing positioning fixture is as follows:

[0034] Before wire drawing, the workpiece to be processed is placed on the positioning table 4. At this time, the balls 13 are evenly distributed in the positioning table 4, which can effectively reduce the friction between the workpiece and the positioning table 4, making it convenient for the initial placement and position adjustment of the workpiece. At the same time, the positioning block 5 can assist the workpiece in precise positioning, so that the workpiece is in a suitable processing position.

[0035] When it is necessary to clamp and fix the workpiece, the electric push rod 10 is activated, and the electric push rod 10 extends to push the push plate 7 to slide along the slide rail 8 on the base 1. Since the slide rod 9 at the bottom of the push plate 7 is adapted to the guide block 14, and the end face of the guide block 14 has a ramp 15, as the push plate 7 slides, the push plate 7 will slide along the ramp 15 onto the guide block 14. During this process, the lower surface of the push plate 7 is slidably connected to the surface of the synchronous plate 11. The movement of the push plate 7 will squeeze the synchronous plate 11, thereby driving the top seat 12 connected to the synchronous plate 11 to slide vertically downward inside the base 1, so that the ball bearing 13 is gradually housed in the base 1. At this time, the clamping plate 6 moves towards the positioning block 5 under the drive of the push plate 7. The inner side wall of the clamping plate 6 cooperates with the outer side wall of the positioning block 5 to tightly clamp and fix the workpiece on the positioning table 4, thereby completing the positioning and clamping operation of the workpiece and providing a stable clamping foundation for subsequent wire drawing processing.

[0036] After the wire drawing process is completed, the electric push rod 10 retracts, and the push plate 7 slides in the opposite direction under the action of the electric push rod 10, releasing the pressure on the synchronous plate 11. At this time, the synchronous plate 11 returns to its original position under the elastic force of the limit spring 20, driving the top seat 12 to rise, and the ball bearing 13 extends out of the positioning table 4 again, making it convenient to remove the processed workpiece. The limit rod 18 and the limit seat 17 cooperate to limit the movement of the synchronous plate 11, preventing it from moving excessively and disengaging, thus ensuring the stability and reliability of the entire fixture structure.

[0037] The above embodiments are merely preferred embodiments of the present utility model and are only used to explain the present utility model, not to limit the present utility model. Any changes, substitutions, combinations, simplifications, modifications, etc., made by those skilled in the art without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
