Description

Technical Field

[0001] This utility model relates to sheet metal clamping fixtures, specifically to a metal backplate dual-station top clamping fixture. Background Technology

[0002] In the machining of metal backing plates, which are flat metal sheets primarily produced through stamping, positioning and clamping are crucial steps to ensure machining accuracy and stability. Existing clamping fixtures often lack the clamping force and positioning accuracy required for high-precision machining. Traditional clamping devices typically employ rigid positioning and fixed clamping methods. While these methods can guarantee workpiece stability to some extent, they often necessitate frequent adjustments or fixture changes when dealing with metal backing plates of different sizes, shapes, or thicknesses, resulting in complex and time-consuming operations. Furthermore, rigid clamping methods can easily damage the workpiece surface, especially in high-precision machining, where even minor deformations or displacements can affect machining quality.

[0003] With the increasing demand for efficient and high-precision machining in the manufacturing industry, the limitations of single-station clamping fixtures are becoming increasingly apparent. In mass production, single-station designs not only lead to low production efficiency but also increase labor costs and equipment downtime. Therefore, there is an urgent need for a dual-station top clamping fixture that can adapt to various specifications of metal backing plates, improve machining efficiency, and enhance clamping stability.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0019] refer to Figures 1-4 The illustrated metal backplate dual-station top clamping fixture includes two parallel side plates 1, which are fixedly connected. A drive assembly 2 is disposed between the two side plates 1. Each side plate 1 is fixedly connected to a positioning assembly and a linkage clamping assembly. The positioning assembly includes two parallel side positioning seats 301, with a stop seat 302 and a support seat 303 disposed between the two side positioning seats 301. Each side positioning seat 301 has a positioning groove 3011, and a clamping assembly is fixedly connected to the side wall of each positioning groove 3011. When the metal back plate is placed, the elastic plunger 304 needs to squeeze the balls of the elastic plunger 304 to both sides at the positioning groove 3011 until it completely passes through the balls. After the balls rebound, it can prevent the metal back plate from falling off. The linkage clamping assembly includes a clamping slide 401, a stop 402, a chuck 403, an eccentric wheel 404 and a spring 405. The output end of the drive assembly 2 is fixedly connected to a rotating shaft 5. The two ends of the rotating shaft 5 pass through the side plates 1 on both sides and are fixedly connected to the eccentric wheels 404 of the two linkage clamping assemblies.

[0020] In one embodiment of this solution, the drive assembly 2 includes a servo motor 201 and a transmission wheel set 202. The rotation of the output end of the servo motor 201 drives the rotating shaft 5 to rotate via the transmission wheel set 202. The housing of the transmission wheel set 202 is fixedly connected to the side plate 1. The output end of the servo motor 201 is fixedly connected to the input end of the transmission wheel set 202, and the output end of the transmission wheel set 202 is fixedly connected to the rotating shaft 5. The side positioning seat 301, the stop seat 302, and the support seat 303 are all fixedly connected to the side plate 1. The side positioning seat 301 is used to position and place the metal back plate. The stop seat 302 is provided with a clearance groove, which mainly makes way for the protruding part of the metal back plate. After the metal back plate is positioned, the stop seat 302 can cooperate with the chuck 403 to clamp the metal back plate. The clamping slide 401 is slidably connected to the side plate 1, and the stop block 402 is fixedly connected to the side plate 1. A spring 405 is located between the clamping slide 401 and the stop block 402. The spring 405 serves two purposes: resetting the clamping slide 401 and buffering the clamping action. An eccentric wheel 404 is rotatably connected to the side plate 1, and a chuck 403 is fixedly connected to the clamping slide 401. A guide rail is fixedly connected to the side plate 1, and the clamping slide 401 is slidably connected to the guide rail, guiding the clamping slide 401 during sliding. The chuck 403 has multiple insertion holes and is fixedly connected to the clamping slide 401 via screws. The chuck 403 can be adjusted in position relative to the clamping slide 401 to accommodate metal back plates of different widths. The eccentric wheel 404 has a guide groove 4041, and a guide rod 406 is fixedly connected to the side plate 1. The guide rod 406 is slidably connected to the guide groove 4041. When the transmission wheel set 202 and the rotating shaft 5 rotate, the rotation of the eccentric wheel 404 is limited by the guide groove 4041.

[0021] The working principle of this utility model is as follows: Before positioning and clamping the metal back plate, the position of the chuck 403 on the clamping slide 401 is first adjusted according to the width of the metal back plate. The position is adjusted by sliding the clamping slide 401 and fixed by the screw. When positioning and clamping, the metal back plate is placed along the positioning groove 3011. The metal back plate will have the balls passing through the elastic plunger 304 abut against the side positioning seat 301. Then, the drive assembly 2 drives the rotating shaft 5 to rotate. The eccentric wheel 404 will also rotate with the rotating shaft 5. During the rotation, the eccentric wheel 404 will push the clamping slide 401 to slide towards the metal back plate and press it against the stop seat 302 to achieve the positioning and clamping of the metal back plate.

[0022] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
