DETAILED DESCRIPTION

[0017] The embodiment of the application provides a safety air bag left and right corner piece welding device, and solves the technical problem that in the prior art, when safety air bag left and right corner pieces are welded, workers usually use welding tools to position and weld the safety air bag left and right corner pieces, and this method is not only inefficient, but also has the problem that the left and right corner pieces are not fixed firmly, and the left and right corner pieces are prone to misalignment in the welding process, thereby affecting product quality.

[0018] The technical scheme in the embodiment of the application is as follows to solve the above problems:

[0019] In order to better understand the above technical scheme, the above technical scheme will be described in detail in combination with the drawings of the specification and specific embodiments.

[0020] A safety air bag left and right corner piece welding device, as shown in Figure 1 , Figure 2 and Figure 3 , comprises a tool plate 1, a lower electrode steel plate seat 2 arranged on the top of the tool plate 1, a front stopper 3 for abutting against the front side of a workpiece, a rear stopper 4 for abutting against the rear side of the workpiece, a support assembly 5 for supporting left and right corner pieces of the workpiece, a positioning mechanism 6 for positioning the left and right corner pieces of the workpiece, and a pressing device 7 for pressing the workpiece. The lower electrode steel plate seat 2 is respectively provided with two groups of front stoppers 3 arranged in symmetry and two groups of rear stoppers 4 arranged in symmetry. The top front side of the tool plate 1 is provided with two groups of pressing devices 7 arranged in symmetry. The top left and right sides of the tool plate 1 are respectively provided with the support assembly 5 and the positioning mechanism 6.

[0021] The lower electrode steel plate seat 2 is provided with two groups of lower electrode L-shaped copper blocks 21 arranged in symmetry. The two groups of lower electrode L-shaped copper blocks 21 are respectively provided with chromium zirconium copper lower electrodes 22.

[0022] The support assembly 5 comprises a first L-shaped plate 51, a second L-shaped plate 52, a connecting plate 53 and a support groove 54. The first L-shaped plate 51 is installed on the tool plate 1. The second L-shaped plate 52 is installed on the first L-shaped plate 51. The connecting plate 53 is installed on the second L-shaped plate 52. The support groove 54 is installed on the connecting plate 53.

[0023] The positioning mechanism 6 comprises a positioning block 61 and a first rotary air cylinder 62 installed on the top of the tool plate 1. The positioning block 61 is arranged on the rotary end of the first rotary air cylinder 62.

[0024] The pressing device 7 comprises a second rotary air cylinder 71, a pressing block 72 for pressing the workpiece, and a pressing air cylinder 73 installed on the top of the tool plate 1. The second rotary air cylinder 71 is installed on the driving end of the pressing air cylinder 73. The pressing block 72 is arranged on the rotary end of the second rotary air cylinder 71.

[0025] When it is necessary to fix and weld the tool, first, the workpiece is placed on the top of the two groups of front stop blocks 3 and the two groups of rear stop blocks 4. At this time, the two groups of L-shaped copper blocks 21 and the two groups of chromium-zirconium copper lower electrodes 22 will abut against the inner side of the workpiece, and the left and right corner pieces of the workpiece will abut against the support grooves 54 in the two groups of support assemblies 5, respectively. Then, the first rotary air cylinder 62 rotary end of the two groups of positioning mechanisms 6 is rotated and drives the two groups of positioning blocks 61 to rotate to the upper side of the two groups of support grooves 54. At this time, the two groups of positioning blocks 61 can fix the left and right corner pieces of the workpiece, respectively. Then, the two groups of pressing devices 7 work. The rotary end of the second rotary air cylinder 71 of the two groups of pressing devices 7 drives the corresponding pressing block 72 to rotate to the upper side of the workpiece, respectively. Then, the driving end of the pressing air cylinder 73 of the two groups of pressing devices 7 is retracted, so that the two groups of pressing blocks 72 are tightly pressed on the top of the workpiece. At this time, the workpiece can be effectively fixed, so that the workpiece can be prevented from being dislocated during welding, thereby ensuring the quality of the workpiece during welding.

The optimization design of this structure avoids the problem of unstable welding quality caused by inaccurate positioning and unstable fixing of the workpiece in traditional welding operation, and significantly improves the product quality. Through the installation of two groups of symmetrically placed lower electrode L-shaped copper blocks 21 on the electrode steel plate seat 2, and the installation of chromium-zirconium copper lower electrodes 22 on the two groups of lower electrode L-shaped copper blocks 21 respectively, the lower electrode L-shaped copper blocks 21 and the chromium-zirconium copper lower electrodes 22 can play a role in positioning and supporting the inner side of the workpiece when the workpiece is placed on the front stopper 3 and the rear stopper 4. Through the cooperative work of the positioning mechanism 6 and the pressing device 7, the left and right corners of the workpiece and the top can be uniformly pressed, so as to ensure the stability of the workpiece during welding, avoid welding defects caused by uneven pressing, and at the same time, the welding operation of the airbag left and right corner parts is more automated, reduces the time and difficulty of manual operation of workers, improves the production efficiency, reduces the dependence of welding operation on skilled workers, and saves the cost of human resources.
