[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The following is combined with Figure 1-5 Described in detail, the workpiece fixing device for mechanical welding includes a support table 101, a lifting support plate 102, a squeeze member and a linkage member. The lifting support plate 102 is slidably connected to the support table 101. Three squeeze members and three linkage members are provided. The three linkage members are fixedly connected to the support table 101 by welding. The three squeeze members are slidably connected to the support table 101 through circular holes. The three squeeze members are respectively in contact with the three linkage members.

[0029] Furthermore, the support table 101 plays a role of bearing connection. Three support legs are arranged on the support table 101 to realize the supporting and fixing treatment of the support table 101. When there is no welding on the lifting tray 102, the three squeezed components will generate elastic force to act on the lifting tray 102, so that the lifting tray 102 moves upward and is at the highest point. After the welded part is placed on the lifting tray 102, the lifting tray 102 is driven to move downward. When the lifting tray 102 moves downward, the three squeezed components can be driven to move downward. When driving the three squeezed components to move downward, the three squeezed components can be separated from the three squeezed components after moving downward. At this time, the three squeezed components can release the restriction on the three squeezed components, and the three squeezed components will move inward to complete the fixing treatment of the welded part and prevent the welded part from moving during the welding process.

[0030] The following is combined with Figure 1-3 In detail, the workpiece fixing device for mechanical welding further includes a limiting protrusion ring 103 , and the limiting protrusion ring 103 is fixedly connected to the lifting support plate 102 by welding.

[0031] Furthermore, the limiting convex ring 103 is used to limit the lifting plate 102. When the limiting convex ring 103 contacts the support table 101, the limiting convex ring 103 completes the limiting process of the lifting plate 102, and the lifting plate 102 will not be able to continue to move upward.

[0032] The following is combined with Figure 1-4 In detail, the linkage component includes a right-angle plate 201, a sliding column 202 and a contact column 203. The sliding column 202 is slidably connected to the right-angle plate 201 through a circular hole. The sliding column 202 is sleeved with a spring I. The contact column 203 is fixedly connected to the sliding column 202 by welding. The three right-angle plates 201 are all fixedly connected to the support table 101 by welding. The support table 101 is slidably connected to the three contact columns 203.

[0033] Furthermore, the right-angle plate 201 plays a supporting and fixing role, and can provide sliding space for the sliding column 202. The three sliding columns 202 are all provided with springs I, and the sliding column 202 can drive the contact column 203 to move downward. When the welded part is placed on the lifting support plate 102, the lifting support plate 102 will move downward, thereby driving the three sliding columns 202 to move downward. The three sliding columns 202 can drive the three contact columns 203 to move downward. When the three contact columns 203 move downward, the three contact columns 203 will contact the three extrusion components. At this time, the three extrusion components will move inward, and the inward movement of the three extrusion components is used to complete the extrusion and fixing of the welded part on the lifting support plate 102, and the fixing of the welded part is completed. When the welded part is removed, the elastic force generated by the springs I on the three sliding columns 202 acts on the three contact columns 203, thereby driving the lifting support plate 102 to move upward, ensuring that the lifting support plate 102 is at the highest point.

[0034] The following is combined with Figure 1 , 2 5 is described in detail, the extrusion component includes a telescopic sliding column 301 and an extrusion sliding plate 302, the telescopic sliding column 301 is slidably connected to the extrusion sliding plate 302, the three telescopic sliding columns 301 are fixedly connected to the support table 101 by welding, the support table 101 is slidably connected to the three extrusion sliding plates 302, and the three extrusion sliding plates 302 are respectively in contact with the three contact columns 203.

[0035] Furthermore, the three telescopic slide posts 301 are all provided with springs II, and the elastic force generated by the springs II provided on the three telescopic slide posts 301 acts on the three extrusion slides 302, so that the three extrusion slides 302 have a tendency to move inwards, and when the three contact posts 203 move downwards, the three contact posts 203 will be released from contact with the three extrusion slides 302. At this time, the elastic force generated by the three springs II acts on the three extrusion slides 302, thereby driving the three extrusion slides 302 to move inwards, allowing the three extrusion slides 302 to contact the welding parts on the lifting support plate 102, thereby completing the welding and fixing processing of the welding parts.

[0036] The following is combined with Figure 1 , 2 5 is described in detail, the extrusion component also includes an angle fixing plate 303, a connecting column 304 and a longitudinal fixing plate 305, the angle fixing plate 303 has two connecting columns 304 fixedly connected by welding, the longitudinal fixing plate 305 is slidably connected to the two angle fixing plates 303 through circular holes, and the three angle fixing plates 303 are respectively fixedly connected to the three extrusion sliding plates 302 by welding.

[0037] Furthermore, springs III are sleeved on the connecting columns 304. The elastic force generated by the three springs III can act on the three longitudinal fixing plates 305, causing the three longitudinal fixing plates 305 to tend to move downward. When the three extrusion slide plates 302 move inward, the three longitudinal fixing plates 305 will also be driven to move inward. The inner ends of the three longitudinal fixing plates 305 are designed with inclined surfaces. When the three longitudinal fixing plates 305 come into contact with the welded parts, the three longitudinal fixing plates 305 can move upward to press the welded parts under the three longitudinal fixing plates 305, completing the longitudinal fixing of the welded parts. At this time, all-round fixing of the welded parts will be achieved, further preventing the welded parts from moving during the welding process.

[0038] The following is combined with Figure 1 , 6 -10 Detailed description, the workpiece fixing device for mechanical welding also includes an adjusting member, a transverse support plate 503 and a fixing claw 601, the adjusting member is fixedly connected to the support table 101 by welding, the transverse support plate 503 and the adjusting member are fixedly connected by welding, and the fixing claw 601 is provided with four, divided into two groups, and the two groups of fixing claws 601 are respectively slidably connected to the two ends of the transverse support plate 503.

[0039] Furthermore, the lateral and longitudinal positions of the cross support plate 503 can be changed by using an adjustment component, and the cross support plate 503 can also be driven to rotate. The cross support plate 503 can provide sliding space for the four fixing claws 601. The two sets of fixing claws 601 can be used to fix the pipe fittings. The shape of the pipe fittings can be a straight pipe, an inclined pipe or a T-shaped pipe. The pipe fittings are brought into contact with the welded parts, and the pipe fittings are welded to the welded parts using a welding gun to complete the welding process of the welded parts.

[0040] The adjustment component includes a transverse sliding seat 401, a lifting seat 402, a load-bearing sliding cavity 403, a limit ring 404, a worm gear II405, a sliding plate 501 and a transverse screw 502.

[0041] Furthermore, the transverse sliding seat 401 can drive the lifting seat 402 to move transversely, thereby driving the fixed pipe fitting to move and ensuring that the pipe fitting is in the correct position of the welded part. The lifting seat 402 can drive the pipe fitting to move up and down, and adjust the height of the pipe fitting according to the length of the pipe fitting. The bearing sliding cavity 403 is fixedly connected with a worm gear II, which is meshed and driven by a worm gear rod II405. Rotating the worm gear rod II405 can drive the bearing sliding cavity 403 to rotate, and finally change the angle of the pipe fitting. According to the different shapes of the pipe fittings, the angle of the pipe fitting needs to be adjusted to ensure that the pipe fitting can be tightly connected to the welded part. The limiting ring 404 plays a limiting role. The bearing sliding cavity 403 is fixedly connected with a reduction motor I, and the output shaft of the reduction motor I is fixedly connected to the transverse moving screw 502. When the transverse moving screw 502 rotates, it can drive the sliding plate 501 to slide, thereby changing the position of the pipe fitting. The position of the pipe fitting is changed from three aspects, further ensuring that the pipe fitting is in the correct position on the welded part, and completing the welding of the pipe fitting to the correct position of the welded part.

[0042] The following is combined with Figure 6 and 9 In detail, the workpiece fixing device for mechanical welding also includes a bidirectional screw 602, of which two are provided. The two bidirectional screws 602 are rotatably connected to the two ends of the cross support plate 503 through holes, and the two sets of fixing claws 601 are respectively connected to the two bidirectional screws 602 through threaded transmission.

[0043] Furthermore, the pipe fittings can be placed on the two fixing claws 601 located at the bottom.

A worm gear I is fixedly connected to the top of the two bidirectional lead screws 602, and the worm gear I can be used to drive the bidirectional lead screws 602 to rotate. Rotating the two bidirectional lead screws 602 can drive the two groups of fixing claws 601 to move inward at the same time, thereby completing the fixing of the pipe fittings. The position of the cross support plate 503 can also be adjusted, thereby changing the position of the pipe fittings fixedly connected between the two groups of fixing claws 601, so that the pipe fittings and the welded parts are in close contact with each other, and the pipe fittings will also be fixed, so that the welding process of the pipe fittings and the welded parts can be realized, and the pipe fittings are fixedly connected to the welded parts.
