Description

Technical Field

[0001] This utility model relates to the field of welding tooling technology, specifically an integrated welding device based on a multi-module quick-change fixture. Background Technology

[0002] In the field of welding fixture technology, the fixture base plate, as the basic support platform of the fixture, plays a core role in supporting and fixing other components of the fixture and constructing the overall fixture structure. Its design rationality directly affects the stability and multi-functional expandability of the fixture. In the existing technology, traditional welding fixtures are usually customized for a single product. When multiple different products need to be produced, the entire set of fixtures or fixture base plates need to be changed frequently. This not only leads to long fixture changeover time and low production efficiency, but also requires a large number of different types of fixture base plates, resulting in waste of base plate resources and low fixture utilization, making it difficult to meet the high-efficiency integration requirements of flexible production of multiple products.

[0003] Based on this, an integrated welding device based on a multi-module quick-change fixture is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, an integrated welding device based on a multi-module quick-change fixture includes: a fixture base plate 1, a base 2, an adjustment mechanism, and a quick-change mechanism; the base 2 is fixedly mounted on the bottom of the fixture base plate 1, and a support foot 3 is fixedly mounted on the bottom of the fixture base plate 1; three guide rails 4 are provided on the top of the fixture base plate 1. An adjustment mechanism for flexibly adjusting the position of the fixture is slidably mounted on the inner wall of the guide rails 4, and a quick-change mechanism for quickly changing the fixture is fixedly mounted on the top of the adjustment mechanism.

[0025] By setting three guide rails 4, it can accommodate the synchronous welding of workpieces of different specifications, thereby improving production efficiency. By setting the base 2 and support feet 3, the load-bearing capacity of the fixture base plate 1 can be increased, thereby improving production stability.

[0026] In one embodiment, such as Figure 2 As shown, the adjustment mechanism includes sliders 5 that are slidably disposed on the inner wall of the guide rail 4, screws 6 that are rotatably disposed on the inner wall of the guide rail 4, guide rods 7 that are fixedly disposed on the inner wall of the guide rail 4, an embedded mounting cavity 8 that is opened inside the fixture base plate 1, a motor 9 that is fixedly disposed on the inner wall of the embedded mounting cavity 8, and the output end of the motor 9 is fixedly connected to the end of the screw 6.

[0027] The screw 6 is driven to rotate by the output end of the motor 9. The screw 6 is threadedly connected to the slider 5, so that the slider 5 slides laterally under the setting of the guide rod 7. At the same time, the slider 5 drives the fixed base plate 10 to move, so as to achieve the effect of flexibly changing the position of the fixture. It can accurately match the welding positioning requirements of workpieces of different specifications. There is no need to customize a fixed base plate for a single product, which greatly enhances the versatility of the base plate for multiple types of products.

[0028] In one embodiment, such as Figure 3 and Figure 4 As shown, the quick-change mechanism includes a fixed base plate 10 fixedly mounted on the top of the slider 5, a support column 11 fixedly mounted on the top of the fixed base plate 10, a connecting plate 12 fixedly mounted on the top of the support column 11, a clamping base plate 13 mounted above the connecting plate 12, a clamping fixture 14 fixedly mounted on the top of the clamping base plate 13, and a clamping assembly for clamping the fixed clamping base plate 13 slidably mounted on the top of the fixed base plate 10.

[0029] The clamping assembly includes two clamping plates 15 slidably disposed on the top of the fixed base plate 10. Each clamping plate 15 has a lever 16 fixedly disposed on its top. A rotating disk 17 is rotatably disposed on the top of the fixed base plate 10. A guide groove 18 adapted to the lever 16 is opened on the top of the rotating disk 17. A mounting bracket 19 is fixedly disposed on the top of the fixed base plate 10. An electric telescopic rod 20 is fixedly disposed on the mounting bracket 19. The output end of the electric telescopic rod 20 is fixedly connected to the clamping plate 15.

[0030] Both the connecting plate 12 and the fixture base plate 13 are provided with clamping limiting grooves adapted to the clamping plate 15. During clamping, the clamping plate 15 is embedded in the clamping limiting grooves for stable clamping, preventing the fixture 14 from shaking. A sliding plate adapted to the clamping plate 15 is fixedly provided on the top of the fixed base plate 10, and the sliding plate is slidably connected to the clamping plate 15. The clamping surface of the clamping plate 15 is covered with a polyurethane layer. The polyurethane layer has high elasticity and softness properties. During clamping, it can evenly distribute pressure through elastic deformation, avoiding indentation on the fixture base plate 13. The fixture 14 includes a first module, a second module, and a third module. Each module can be used separately to produce product A. The first and third modules can be used together to produce product B. The second and third modules can be used together to produce product C. By combining different fixture components, different products can be produced. Unlike previous single-product fixtures, multi-product switching can be achieved, saving a lot of fixture switching time and costs.

[0031] By placing the fixture 14 to be installed on the fixture base plate 13, the output end of the electric telescopic rod 20 pushes the clamping plate 15 to slide on the fixed base plate 10. Simultaneously, the clamping plate 15 drives the lever 16 to move laterally. The lever 16, under the action of the guide groove 18, drives the rotating disk 17 to rotate. At this time, the guide groove on the rotating disk 17 drives another clamping plate 15 to slide and clamp synchronously. Then, the clamping plate 15 is embedded in the clamping limiting groove on the fixture base plate 13, preventing the fixture 14 from sliding while clamping. Different types of products can be manufactured through combinations of different fixtures.

[0032] The above embodiments disclose an integrated welding device based on a multi-module quick-change fixture. The adjustment mechanism allows for flexible adjustment of the fixture position via three guide rails 4 on the top of the fixture base plate 1. A slider 5 slides along the inner wall of each guide rail 4, and a screw 6 and a guide rod 7 are located within each guide rail 4. A motor 9 is fixed in the embedded mounting cavity 8 of the fixture base plate 1, and its output drives the screw 6 to rotate. Since the slider 5 is threadedly connected to the screw 6, the rotation of the screw 6 causes the slider 5 to slide laterally along the guide rod 7, thereby pushing the fixed base plate 10 and the quick-change mechanism above it to move. By precisely controlling the displacement of the slider 5 with the motor 9, the device can adapt to the welding positioning requirements of workpieces of different specifications without needing to replace the fixture base plate 1, significantly improving the versatility of multi-product production.

[0033] The quick-change mechanism enables rapid replacement of the fixture 14 via a clamping assembly. When a fixture needs to be replaced, the electric telescopic rod 20 pushes the clamping plate 15 to slide on the fixed base plate 10, and the lever 16 on the top of the clamping plate 15 is embedded in the guide groove 18 of the rotating disk 17. The lateral movement of the lever 16 drives the rotating disk 17 to rotate, thereby synchronously driving the clamping plate 15 on the other side to slide in the opposite direction. The two clamping plates 15 are embedded in the clamping limiting grooves of the fixture base plate 13 and the connecting plate 12, and the clamping pressure is dispersed by the polyurethane layer to avoid indentation. When released, the electric telescopic rod 20 retracts, and the clamping plate 15 exits the limiting groove, allowing the fixture base plate 13 and the fixture 14 to be quickly removed, realizing the combination and switching of different modules and meeting the high-efficiency production needs of multiple types of products.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
