[0003] Therefore, when welding and processing products, the double-station welding fixture is one of the indispensable important components. However, most of the current double-station welding fixtures on the market need to be manually clamped by workers, which will consume a lot of time during the clamping process, undoubtedly reducing the production efficiency.

[0004] Therefore, it is urgent to improve the double-station welding fixture to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a double-station welding fixture. Workers only need to place the products to be processed, and the products can be clamped and limited by an electrically driven pressing device, greatly improving the production efficiency.

[0006] To achieve the above purpose, the main technical solutions adopted by the utility model include: an operation table, and a first clamping mechanism and a second clamping mechanism arranged on the surface of the operation table. The first clamping mechanism includes a vertical plate, a connecting plate fixedly arranged on one side of the vertical plate, and a limiting base for placing the products in a limited way.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The following will describe in detail the embodiments of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0029] As Figures 1-4As shown in the figure, a double-station welding fixture includes an operating table 1, and a first clamping mechanism 101 and a second clamping mechanism 201 arranged on the surface of the operating table 1, which can fix and limit the products to be welded through the first clamping mechanism 101 and the second clamping mechanism 201. The first clamping mechanism 101 includes a vertical plate 102, a connecting plate 103 fixedly arranged on one side of the vertical plate 102, and a limit base 104 for placing the products in a limited position. The second clamping mechanism 201 includes a fixing plate 202, a placing base 204, and a telescopic rod 205 for pressing and limiting the products. The setting of the first clamping mechanism 101 and the second clamping mechanism 201 can divide the operating table 1 into two stations, providing multiple stations for workers to use. It can not only enable multiple workers to perform welding and clamping alternately, but also provide welding stations for multiple workers. Furthermore, by reducing the operation steps of workers or having multiple workers operate simultaneously, and workers only need to place the products to be processed, the products can be clamped and limited by an electrically driven pressing device, greatly improving production efficiency. At the same time, the shapes of the limit base 104 and the placing base 204 are different, which can be suitable for placing products of different materials.

[0030] Several driving motors 3 for fixing and limiting the products are arranged on the surface of the operating table 1. Among them, at least four driving motors 3 are installed on the first clamping mechanism 101. At least two driving motors 3 are installed on the second clamping mechanism 201. The driving motors 3 can fix the positions of the products to be processed to prevent the products from deforming during welding. At least three welding pipes 5 are placed on both the limit base 104 and the placing base 204. Among them, a limit head 501 is fixedly arranged at the top of the middle of every three welding pipes 5. Limit seats 6 are fixedly arranged on the sides of the vertical plate 102 and the fixing plate 202 close to the products. The limit seats 6 are used for further limiting the products. The limit seats 6 arranged on one side of the vertical plate 102 and the fixing plate 202 can limit the welding pipes 5 in the middle and longer ones. And the width of the limit head 501 is greater than the groove of the limit seat 6, so that the longer welding pipes 5 will not slide down after being limited. At the same time, the driving motors 3 installed on the first clamping mechanism 101 can fix and limit the welding pipes 5 in the recesses of the limit base 104, so that the positions of the welding pipes 5 are fixed and restricted for the workers' welding. The driving motors 3 installed on the second clamping mechanism 201 can limit and fix the welding pipes 5 on the surface of the placing base 204 for the workers' welding and processing. At the same time, the driving motors 3 can limit and fix the longer welding pipes 5 in the groove parts of the limit seats 6.

[0031] Furthermore, as Figure 1As shown in the figure, one of the driving motors 3 is vertically and fixedly arranged on one side of the connecting plate 103. At least three driving motors 3 are installed on the periphery of the limiting base 104. By fixedly installing the connecting plate 103 on the back of the vertical plate 102, one of the driving motors 3 can be vertically installed through the connecting plate 103, so as to limit and fix the longer welding pipe 5 located on the first clamping mechanism 101. The three driving motors 3 arranged on the periphery of the limiting base 104 can greatly improve the degree of limiting and fixing.

[0032] Further, as Figure 2 and Figure 3 shown in the figure, one of the driving motors 3 is horizontally and fixedly connected to the fixing plate 202 through the connecting plate 203. The connecting plate 203 is fixedly arranged on one side of the fixing plate 202. At least one driving motor 3 is installed on one side of the placing base 204. A top plate 7 is fixedly arranged at one end of the fixing plate 202 away from the operating table 1. The telescopic rod 205 is fixedly connected to the top plate 7 through the limiting rod 9. The output end of the telescopic rod 205 penetrates through the top plate 7 and extends above the limiting seat 6. A pressing plate 8 is fixedly arranged at one end of the telescopic rod 205 close to the limiting seat 6. One end of the pressing plate 8 is fixedly provided with a spring 206. The end of the spring 206 away from the pressing plate 8 is fixedly connected to the top plate 7. The spring 206 is slidably connected to the telescopic end of the telescopic rod 205. The telescopic rod 205 is fixed to the top plate 7 through the limiting rod 9. At the same time, the telescopic rod 205 uses the pressing plate 8 and the top plate 7 to make its telescopic end always keep the extended state through the spring 206, so as to press the limiting head 501 arranged at the top of the longer welding pipe 5 by using the limiting seat 6, avoid the welding pipe 5 from moving during the welding process, and the driving motor 3 arranged on the connecting plate 203 can provide a further limiting and fixing effect.

[0033] Further, as Figure 1 shown in the figure, two switch rods 4 are fixedly installed on the surface of the operating table 1. The switch rods 4 are used for the switches of multiple driving motors 3. The driving motors 3 installed on the first clamping mechanism 101 and the second clamping mechanism 201 can be respectively controlled to be switched on and off through the two switch rods 4, so that the driving motors 3 on the first clamping mechanism 101 and the second clamping mechanism 201 are not at the same control end, which is convenient for the alternating operation of multiple workers.

[0034] Even further, as Figure 4As shown in the figure, a push block 13 is fixedly arranged at the output end of the driving motor 3. The push block 13 is rotatably connected with a limit swing arm 11. A pressing block 12 is fixedly arranged on one side of the limit swing arm 11. A limit support platform 10 is fixedly arranged at the upper end of the driving motor 3. The limit support platform 10 is rotatably connected with the limit swing arm 11 through a positioning arm 14. When the driving motor 3 is started, an upward or downward force can be provided to the push block 13, so that the push block 13 can be lifted or lowered. Furthermore, the limit swing arm 11 rotatably connected therewith can be pushed upward or pulled downward. Subsequently, the limit swing arm 11 can limit and fix or release the welding pipe 5 through the pressing block 12. The settings of the limit support platform 10 and the positioning arm 14 can limit the swing amplitude of the limit swing arm 11, preventing the limit swing arm 11 from failing to play a role in limiting and fixing.

[0035] As Figures 1-4 shown, the principle of the double-station welding fixture provided in this embodiment is as follows:

[0036] Setting the first clamping mechanism 101 and the second clamping mechanism 201 can divide the operation table 1 into two stations, providing multiple stations for workers to use. It can not only enable multiple workers to perform welding and clamping alternately, but also provide welding stations for multiple workers. Thus, by reducing the operation steps of workers or enabling multiple workers to operate simultaneously, the production efficiency is greatly improved. The limit seat 6 provided on one side of the vertical plate 102 and the fixed plate 202 can limit the relatively long welding pipe 5 in the middle. Moreover, the width of the limit head 501 is greater than the groove of the limit seat 6, enabling the relatively long welding pipe 5 not to slide downward after being limited. At the same time, the driving motor 3 installed on the first clamping mechanism 101 can fix and limit the welding pipe 5 in the recess of the limit base 104, so that the position of the welding pipe 5 is fixed and restricted for the welding of workers. The driving motor 3 installed on the second clamping mechanism 201 can limit and fix the welding pipe 5 on the surface of the placing base 204 for the welding processing of workers.
