Description

Technical Field

[0001] The utility model relates to the technical field of bridge steel structure processing, in particular to a tooling platform for bridge steel structure processing. Background Art

[0002] The steel bridge deck is welded from several bridge deck units. The bridge deck is prone to deformation after welding. The deformation problem can be solved by welding the bridge deck using the reverse deformation method. Therefore, a tooling processing platform that can avoid deformation is needed to solve the deformation problem of the bridge deck after welding. The existing tooling platforms are mainly fixed platform types. The disadvantage is that when welding or processing products on such fixed platforms, some products need to be turned over and re-clamped for welding. Such process decomposition and repeated clamping will inevitably lead to low production efficiency. Summary of the invention

[0003] In order to solve the above problems, the utility model discloses a tooling platform for processing bridge steel structures, which causes the welded parts to deform in the opposite direction before welding to offset the deformation after welding. At the same time, the workbench can be turned over at will to facilitate the welding of workpieces.

[0004] The utility model is realized by the following technical solutions:

[0005] A tooling platform for processing bridge steel structures includes a left column, a right column, and a workbench. Both ends of the workbench are connected with rotating shafts, and the rotating shafts are connected to motors arranged in the columns. A plurality of workpiece clamps are arranged on the workbench. Support shaft A and support shaft B are fixed to the upper and lower surfaces of the workbench. The support shaft A is fixed to both ends of the workbench, and the support shaft B is fixed to the middle of the workbench. The diameter of the support shaft B is smaller than the diameter of the support shaft A. Processing part A and processing part B are respectively arranged above and below the workbench. Jack A is arranged above the processing part A, and jack B is arranged below the processing part B.

[0006] The jack A is located in the middle of the workpiece A, and the top end of the jack A is fixed on the crossbeam above it.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model has a novel structure, is simple and practical; a workbench is provided with supporting shafts with different radii, and a jack is used to pre-deform the workpiece in the opposite direction before welding, thereby offsetting the deformation after welding and ensuring that the workpiece is not deformed after welding; the workpiece can be fixed on both the upper and lower sides of the workbench, and the upper and lower workpieces can be processed simultaneously, and the device has high processing efficiency; the workbench can be turned over at will, which is convenient for workpiece welding.

[0011] The utility model is further described below in conjunction with the accompanying drawings:

[0012] A tooling platform for processing bridge steel structures includes a left column 1, a right column 2, and a workbench 5. The two ends of the workbench 5 are connected with a rotating shaft 12, and the rotating shaft 12 is connected to a motor 10 arranged in the column. The workbench 5 is provided with a plurality of workpiece clamps 8. The upper and lower surfaces of the workbench 5 are fixed with a support shaft A 9 and a support shaft B 11. The support shaft A 9 is fixed at the two ends of the workbench 5, and the support shaft B 11 is fixed in the middle of the workbench 5. The diameter of the support shaft B 11 is smaller than the diameter of the support shaft A 9. A processing part A 3 and a processing part B 4 are respectively provided at the upper and lower parts of the workbench 5. A jack A 6 is provided above the processing part A 3, and a jack B 7 is provided below the processing part B 4.

[0013] The jack A 6 is located in the middle of the workpiece A 3 , and the top end of the jack A 6 is fixed on the crossbeam above it.

[0014] As shown in the attached figure of the instruction manual Figure 1 As shown, a tooling platform for processing bridge steel structures includes a left column 1, a right column 2, and a workbench 5. The two ends of the workbench 5 are connected with a rotating shaft 12, and the rotating shaft 12 is connected to a motor 10 arranged in the column. A plurality of workpiece clamps 8 are arranged on the workbench 5. The upper and lower surfaces of the workbench 5 are fixed with a supporting shaft A 9 and a supporting shaft B 11. The supporting shaft A 9 is fixed at the two ends of the workbench 5, and the supporting shaft B 11 is fixed in the middle of the workbench 5. The diameter of the supporting shaft B 11 is smaller than the diameter of the supporting shaft A 9. A processing part A 3 and a processing part B 4 are respectively arranged above and below the workbench 5. A jack A 6 is arranged above the processing part A 3, and a jack B 7 is arranged below the processing part B 4.

[0015] The jack A 6 is located in the middle of the workpiece A 3 , and the top end of the jack A 6 is fixed on the crossbeam above it.

[0016] The use process of this device is as follows: fix the workpiece A3 and the workpiece B4 on the upper and lower sides of the workbench 5 respectively through the workpiece clamp 8, apply force to the workpiece A3 through the jack A6, and apply force to the workpiece B4 through the jack B7. Since the diameter of the middle support shaft B 11 is smaller than the diameter of the support shaft A 9 at both ends, the workpiece is deformed by the force. The deformation before welding is opposite to the deformation of the workpiece after welding. The pre-deformed workpiece is welded again. Turning on the motor 10 can realize the arbitrary flipping of the workbench 5, which is convenient for welding the workpiece.

[0017] The utility model has a novel structure, is simple and practical; a workbench is provided with supporting shafts with different radii, and a jack is used to pre-deform the workpiece in the opposite direction before welding, thereby offsetting the deformation after welding and ensuring that the workpiece is not deformed after welding; the workpiece can be fixed on both the upper and lower sides of the workbench, and the upper and lower workpieces can be processed simultaneously, and the device has high processing efficiency; the workbench can be turned over at will, which is convenient for workpiece welding.
