Description

Technical Field

[0001] The utility model relates to the technical field of chassis processing, in particular to a chassis column welding tool. Background Art

[0002] The existing chassis welding jig assembly usually has an unfixed placement of the components to be assembled, which causes shaking and errors during welding. In addition, factors such as welding heat can cause deformation and misalignment, resulting in poor verticality of the product after welding and cooling. Moreover, the products welded with the welding jig are often not standardized. The material placement and welding processes are labor-intensive and work efficiency is relatively low.

[0003] Therefore, the applicant has found a solution to the above-mentioned problem through beneficial exploration and research. The technical solution to be introduced below is produced in this context. Utility Model Content

[0010] a second cylinder device movably arranged at the bottom of the workbench and for mounting the shaft sleeve, and

[0011] A control switch for controlling the operation of the first cylinder device and the second cylinder device.

[0012] In a preferred embodiment of the present invention, the workbench is provided with an inner hole for the sleeve to pass through and be placed on the second cylinder device.

[0013] In a preferred embodiment of the present invention, there are two first cylinder devices, and the two first cylinder devices are respectively arranged on both sides of the workbench.

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0033] See also Figures 1 to 12 The chassis column welding tool shown includes a workbench 10, a positioning boss 20, a first cylinder device 30, a second cylinder device 40, and a control switch for controlling the operation of the first cylinder device 30 and the second cylinder device 40. The control switch in this embodiment is preferably a pneumatic switch.

[0034] In this embodiment, the workbench 10 is provided with an inner hole 10 a for the sleeve 1 to pass through and be placed on the second cylinder device 40 .

[0035] The positioning boss 20 is disposed on the workbench 10 and is used to limit the position of the chassis 2 .

[0036] A first cylinder assembly 30 is movably mounted on the side of the workbench 10 and is used to compress the chassis 2. In this embodiment, two first cylinder assemblies 30 are preferably provided, one on each side of the workbench 10. Each first cylinder assembly 30 includes a first cylinder 31, a rotating arm 32 movably mounted on the first cylinder 31, and a quick-clamping arm 33 mounted on and connected to the rotating arm 32. During operation, a control switch activates the first cylinder 31, thereby activating the rotating arm 32. The rotating arm 32 rotates to the working area of ​​the workbench 10, causing the quick-clamping arm 33 to compress the chassis 2.

[0037] The second cylinder device 40 is movably disposed at the bottom of the workbench 10 and is provided for mounting the sleeve 1. In this embodiment, the second cylinder device 40 comprises a second cylinder 41 and a circular shaft 42 movably disposed on the second cylinder 41 and provided for mounting the sleeve 1.

[0038] A circular hole 2 a is provided in the middle of the chassis 2 to match the shaft sleeve 1 , and mounting holes 2 b are provided at the four corners of the chassis 2 to connect with the positioning bosses 20 .

[0039] The working principle of this utility model is as follows:

[0040] 10 , and the second cylinder 41 is in the state of inward contraction of the circular shaft 42. Then, the sleeve 1 is placed on the circular shaft 42 of the second cylinder 41 from the inner hole 10a of the workbench 10, and the chassis 2 is placed on the table top of the workbench 10. The four positioning bosses 20 on the workbench 10 are used to limit the chassis 2 so that the bottom of the chassis 2 is flush with the plane of the workbench 10. The air pressure switch is turned on, and the first cylinder 31 and the second cylinder 41 are adjusted to the air intake and pressurization state. The rotating arm 32 of the first cylinder 31 rotates 90 degrees to place the quick clamping arm 33 above the chassis 2, and at the same time presses down the upper surface of the chassis 2 to adjust the horizontal direction and The vertical directions are all limited and fixed, and the circular shaft 42 of the second cylinder 41 pushes the sleeve 1 upward, so that the sleeve 1 cannot move in the horizontal direction, and uses its own weight to maintain a fit with the workbench 10 in the vertical direction. Since one end of the sleeve 1 is flush (this surface is flush with the circular shaft 42 surface of the second cylinder 41), the other end of the sleeve 1 has an inclined angle (this surface is flush with the upper surface of the chassis 2). Therefore, the sleeve 1 is placed well and is pushed up by the circular shaft 42 of the second cylinder 41. The end of the sleeve 1 with the inclined angle may not be flush with the upper surface of the chassis 2. At this time, the sleeve 1 can be manually rotated to adjust the flushness; when all parts are clamped, the connection between the chassis 2 and the sleeve 1 is welded from the upper surface to form a whole. Since the chassis and the sleeve are clamped and fixed, deformation and dislocation will not be caused by factors such as welding heat during the welding process, thereby ensuring the verticality of the product after welding and cooling. Finally, after the welding is fixed, the workbench 10 is adjusted to the pressure relief state through the air pressure switch, the first cylinder 31 is stretched upward and rotated outward, the quick clamping arm 33 is separated from the chassis 2, the circular shaft 42 of the second cylinder 41 is retracted inward, and the circular shaft 42 of the second cylinder 41 is separated from the sleeve 1, and the welded workpiece is taken out vertically upward.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
