[0002] When welding the chassis body of a car, the workpiece needs to be fixed first before welding. Since the heights of the workpieces to be welded are different, some workpieces will be suspended. Therefore, when supporting and fixing these workpieces, it is necessary to use gaskets and other clamps to support the bottom of the workpiece to prevent the workpiece from shaking and causing errors during welding. In addition, during the welding process, some small workpieces need to be welded to the chassis workpiece.

[0003] According to the invention patent application with patent number: CN117680892A and publication date of 2024-03-12, a welding tool for automobile chassis is disclosed, including a tool frame, a support frame, a segmented welding mechanism and an angular positioning mechanism. The support frame is symmetrically arranged at the upper end of the tool frame for placing the automobile chassis body. There are multiple segmented welding mechanisms installed on both sides of the tool frame, and used to perform interval segmented welding on the automobile chassis body. The angular positioning mechanism is also installed on both sides of the tool frame, and is used to prevent angular shrinkage during welding of the automobile chassis body. Its main technical effect is: the automobile chassis is positioned respectively by the segmented welding mechanisms on both sides of the tooling frame, the output end of cylinder one drives the connecting plate to move downward along the guide column, and under the pulling action of the connecting rod, drives the pressure arm to flip downward around the hinge with the guide column, until the buffer plate at the end of the pressure arm respectively abuts against the straight side section and the curved side section of the automobile chassis body, and the output end of cylinder two drives the angular covering part to move to the corresponding designated positions in front and behind the forward structure, thereby achieving the purpose of welding in intervals and segments, avoiding the continuous welding method where cracks in the fusion line often occur at the residual stress deformation, and the angular covering part can respectively cover and expose the forward structure of the automobile chassis during the welding process, and the welding protection is performed in a covering manner, which can avoid the angular expansion and contraction of the forward structure of the automobile chassis during the cooling process.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] See also Figure 1 —8. A welding tool for automobile chassis, comprising a base 1, on which a supporting plate 11 is arranged, and also comprising a first clamping welding mechanism 2 and a second clamping welding mechanism 3 arranged on the base 1, wherein the first clamping welding mechanism 2 is slidably arranged on the base 1, and the second clamping welding mechanism 3 is arranged on the base 1, and the chassis is clamped on the base 1 by the first clamping welding mechanism 2 and the second clamping welding mechanism 3, and the workpiece is welded to the chassis.

[0030] A plurality of supporting plates 11 are arranged on the base 1, and the automobile chassis can be supported by the supporting plates 11 to prevent the automobile chassis from falling. A first clamping welding mechanism 2 and a second clamping welding mechanism 3 are arranged on the base 1. Specifically, the first clamping welding mechanism 2 is slidably connected to the base 1. The first clamping welding mechanism 2 includes a bottom plate 21, a slide rail, a first clamping head 22, a second clamping head 23, a manual mechanism 24 and a first driving cylinder 25. The bottom plate 21 is slidably connected to the base 1, and the slide rail is fixedly installed on the outer wall of the bottom plate 21. The first clamping head 22 and the second clamping head 23 are slidably connected to the slide rail respectively. The manual mechanism 24 is respectively connected to the first clamping head 22 and the second clamping head 23. Specifically, the manual mechanism 24 includes a first rotating seat 241, a second rotating seat 242, a first rotating rod 243 and a second rotating rod 244. The first rotating seat 241 and the second rotating seat 242 are respectively fixedly installed on the first clamping seat 52 and the second clamping seat 52. One end of the first rotating rod 243 is rotatably connected to the first rotating seat 241, one end of the second rotating rod 244 is rotatably connected to the first rotating seat 241, and the other end of the second rotating rod 244 is rotatably connected to the first rotating rod 243. When in use, the operator rotates the first rotating rod 243. When the first rotating rod 243 rotates, the second rotating rod 244 is driven to keep rotating. Since the first rotating rod 243 and the second rotating rod 244 are respectively rotatably connected to the first rotating seat 241 and the second rotating seat 242, the first clamping head 22 and the second clamping head 23 can be driven to separate from or approach each other, thereby manually clamping the workpiece to be welded. A limit block is set on the bottom plate 21 to prevent the first clamping head 22 or the second clamping head 23 from detaching from the slide rail. Further, as Figure 4 and Figure 5 As shown, one end of the first driving cylinder 25 is connected to the second clamping head 23, and the output end of the first driving cylinder 25 is connected to the first clamping head 22. The first driving cylinder 25 can drive the first clamping head 22 and the second clamping head 23 to automatically clamp or release the workpiece. The first clamping head 22 and the second clamping head 23 are both provided with welding heads, which can realize automatic welding. The welding heads are conventional technical means in the field, and the principle and structure of their realization are not described in detail here.

[0031] A transverse cylinder is arranged on the outer wall at the bottom of the base 1, and the output end of the transverse cylinder is connected to the bottom plate 21. The bottom plate 21 can be driven to keep moving by the transverse cylinder. When in use, the bottom plate 21 is first moved out by the transverse cylinder, and then the operator clamps the workpiece by the manual mechanism 24. After the chassis is fixed, the bottom plate 21 is reset by the transverse cylinder for welding.

[0032] As an embodiment provided by the utility model, Figure 2 and Figure 3As shown, the second clamping welding mechanism 3 includes a first rotating cylinder 31, a connecting frame 32 and a rotating clamping unit 33. The first rotating cylinder 31 is fixedly installed on the outer wall of one side of the base 1, and the connecting frame 32 is fixedly installed on the output end of the first rotating cylinder 31. Specifically, the connecting frame 32 is a "T"-shaped structure, and the number of the rotating clamping units 33 is two. The two rotating clamping units 33 are respectively installed on the connecting frame 32 of the "T"-shaped structure. The connecting frame 32 is driven by the first rotating cylinder 31 to keep rotating, and then the workpiece connected to the rotating clamping unit 33 can be driven to keep rotating, and the workpiece is placed on the chassis for welding. Further, the rotating clamping unit 33 includes a first telescopic cylinder 331, a rotating rod 332, a connecting rod 333 and a connecting seat 334, as shown Figure 3 As shown, the connecting rod 333 is fixedly connected to the connecting frame 32, the connecting seat 334 is connected to one end of the connecting rod 333, the first telescopic cylinder 331 is fixedly installed on the connecting seat 334, one end of the rotating rod 332 is rotatably connected to the output end of the first telescopic cylinder 331, and one end of the connecting rod 333 is rotatably connected to one end of the rotating rod 332. When the output end of the first telescopic cylinder 331 remains telescopic, the rotating rod 332 can be driven to keep rotating. Since one end of the connecting rod 333 is on the rotating rod 332, the rotating rod 332 can be swung at one end of the connecting rod 333, so that the workpiece can be clamped, and the first rotating cylinder 31 is cooperated to place the workpiece on the outer wall of the chassis.

[0033] As a further embodiment provided by the present utility model, Figure 1 and Figure 7 As shown, a clamping mechanism 4 is respectively provided at the four corners of the base 1, and the clamping mechanism 4 includes a supporting block 41, a second rotary cylinder 42 and a clamping block 43. The second rotary cylinder 42 is fixedly mounted on the base 1, the supporting block 41 is fixedly mounted on the base 1, and the clamping block 43 is fixedly mounted on the output end of the second rotary cylinder 42. When in use, the clamping block 43 is first rotated outward by the second rotary cylinder 42, and the chassis is placed on the base 1 by a mechanical arm or a sling, and the chassis is positioned by the positioning pins provided on the supporting plate 11 and the base 1, and then the clamping block 43 is reset by the second rotary cylinder 42, thereby fixing the four corners of the chassis.

[0034] Furthermore, a floating clamping mechanism 5 is provided on the base 1, and the floating clamping mechanism 5 includes a third rotary cylinder 51, a clamping seat 52 and a rotary clamping head 53. The third rotary cylinder 51 is fixedly mounted on the base 1, and the rotary clamping head 53 is fixedly mounted on the output end of the third rotary cylinder 51. A positioning pin is provided on the clamping seat 52, and the chassis can be positioned by the positioning pin when the chassis is placed. The third rotary cylinder 51 drives the rotary clamping head 53 to keep rotating to fix the side of the chassis. A lifting cylinder 12 is provided on the base 1, and a supporting seat 13 is provided at the output end of the lifting cylinder 12. The lifting cylinder 12 drives the supporting seat 13 to move upward to support the chassis, and then descends, which can facilitate the positioning of the chassis. It should be pointed out that the position and number of the lifting cylinder 12 are designed according to the chassis to be clamped.

[0035] As an embodiment provided by the utility model, Figure 7 As shown, a supporting and clamping mechanism 6 is provided on the outer wall of one side of the base 1, and the supporting and clamping mechanism 6 includes a supporting portion 61, a second telescopic cylinder 62, a rotating clamping plate 63 and a rotating rod 64. The supporting portion 61 is fixedly installed on the base 1, the second telescopic cylinder 62 is fixedly installed on the base 1, the rotating clamping plate 63 is rotatably connected to the output end of the second telescopic cylinder 62, one end of the rotating rod 64 is rotatably connected to the second telescopic cylinder 62, and the other end of the rotating rod 64 is rotatably connected to the rotating clamping plate 63. Specifically, the supporting and clamping mechanism 6 is arranged near the center position of the base 1. When in use, the second telescopic cylinder 62 drives the rotating clamping plate 63 to open, and then the chassis is placed on the base 1. The center position of the base is supported by the supporting portion 61, and then the rotating clamping plate 63 is driven to reset by the second telescopic cylinder 62. Since the rotating clamping plate 63 is rotationally connected to the output end of the second telescopic cylinder 62 and is rotationally connected to the outer wall of the second telescopic cylinder 62 through the rotating rod 64, the rotation of the rotating clamping plate 63 can be controlled by telescoping the output end of the second telescopic cylinder 62.

[0036] It should be pointed out that the number of the floating clamping mechanism 5, the supporting clamping mechanism 6, the second clamping welding mechanism 3 and the first clamping welding mechanism 2 are all two, which are generally symmetrically arranged on the base 1, and their specific positions need to be adjusted according to the type of base produced.

[0037] The utility model clamps the chassis on the base 1 by means of the first clamping welding mechanism 2 and the second clamping welding mechanism 3 provided on the base 1, and welds the workpieces to be welded, replacing manual welding or welding by a robot arm, thereby reducing production costs and improving production efficiency.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
