Description

Technical Field

[0001] The utility model relates to an assembly welding device, in particular to a universal assembly welding device for passenger room door columns. Background Art

[0002] With the continuous advancement of science and technology, subways have been widely used in various cities. The increasing speed of rail vehicles has placed increasingly stringent requirements on the safe operation of rail vehicles. The quality and welding performance of rail vehicle bodies are crucial to the safe operation of rail vehicles. The side wall door columns of aluminum alloy bodies are prone to weld defects or post-weld deformation during the welding process due to insecure fixing, which cannot guarantee and meet the technical requirements of aluminum alloy body passenger compartment doorways. Furthermore, different door columns have different sizes, and welding different door columns requires the use of different tooling, which is cumbersome, labor-intensive, and inefficient. Utility Model Content

[0003] The technical problem to be solved by the utility model is that in the prior art, the work efficiency is low because door posts of different sizes need to be replaced with different tooling.

[0004] In order to solve the above technical problems, the present invention provides a technical solution:

[0005] A universal passenger room door column assembly and welding device includes a base and a support frame, an upper end surface of the base is provided with an adjustment block with a T-slot, each T-slot is provided with a positioning block, the support frame is provided on one side of the upper end surface of the base, the support frame is provided with a groove opening upward, an L-shaped rotating arm is provided in the groove, one end of the L-shaped rotating arm is provided in the groove, and the other end extends to the upper position of the base, and the L-shaped rotating arm located above the base is provided with a threaded hole that passes through from top to bottom, and a tightener is provided in the threaded hole.

[0006] Furthermore, the lower size of the positioning block matches the size of the T-slot, and the upper size matches the size of the corresponding door column. The lower part of the positioning block can slide in the T-slot, which is convenient for replacing positioning blocks of different sizes when welding door column profiles of different sizes. Positioning blocks of different sizes refer to positioning blocks with the same lower size and different upper sizes. In this way, there is no need to replace the adjustment block. Only the positioning blocks with the same lower size and different upper sizes need to be replaced to adapt to door column profiles of different sizes.

[0007] There is a gap between the positioning blocks. When placing the door column profile, the lower weld to be welded is placed in the gap between the positioning blocks to facilitate welding.

[0008] Furthermore, the support frame includes a plane end and a groove end, the plane end is arranged at the end close to the door column profile where it is required to be placed, the groove end is arranged on the rear side of the plane end, and the groove end is provided with the groove opening upward, and the groove runs through the front and rear side surfaces of the groove end.

[0009] Furthermore, a first positioning hole and a second positioning hole separated from each other in upper and lower directions are provided at a side end of the groove end, and both the first positioning hole and the second positioning hole pass through the left and right sides of the groove end.

[0010] Furthermore, the L-shaped rotating arm located in the groove is provided with connecting holes corresponding to the first positioning hole and the second positioning hole, and the L-shaped rotating arm and the support frame are connected together by two pins through the first positioning hole, the second positioning hole and the corresponding connecting holes respectively. After removing the pin located in the first positioning hole above, the L-shaped rotating arm can rotate in the groove around the pin in the second positioning hole, so that the L-shaped rotating arm can be rotated to the outside when placing the door column profile to avoid blocking the placement of the door column profile on the positioning block.

[0011] Furthermore, the clamping device includes a screw, a clamping block and a rotating rod. A through hole is provided on the upper end side of the screw, and the rotating rod is provided in the through hole. The size of the screw matches the size of the threaded hole. After the screw is provided in the threaded hole, it is connected to the clamping block. A threaded groove is provided on the clamping block, and the clamping block is connected to the screw through the threaded groove thereon. Rotating the rotating rod can drive the screw to move up and down in the threaded hole, thereby driving the clamping block to move up and down, thereby tightening and loosening the door column on the positioning block.

[0012] Furthermore, the plane end and the end of the positioning block that contacts the profile are both provided with nylon blocks to prevent the door column profile from being scratched.

[0013] The beneficial effects of the utility model are:

[0014] 1. In the utility model, positioning blocks and clamps are used to compress and fix the door column profiles. The welds are placed between the positioning blocks and are firmly fixed. When the welds are welded, weld defects or deformation after welding are not likely to occur, which can ensure and meet the technical requirements of the aluminum alloy vehicle body passenger compartment door.

[0015] 2. The positioning blocks in the utility model can be replaced. When welding door column profiles of different sizes, it is sufficient to place corresponding positioning blocks of different sizes without replacing the entire tooling, thereby improving overall work efficiency.

[0016] 3. In the present invention, the clamping block and the screw are connected by threads. Compressing blocks of different sizes can be replaced to correspond to door column profiles of different sizes, so as to clamp and fix door column profiles of different sizes, which is convenient for subsequent welding of door column profiles.

[0017] 4. In the present invention, both the plane end and the end of the positioning block that contacts the door column profile are provided with nylon blocks to prevent the door column profile from being scratched, thereby ensuring the aesthetics and ornamental value of the surface of the door column profile.
