Embodiment
[0036] Example: such as Figure 8 ~ Figure 11 As shown, each component of the positioning and clamping device of the present invention can be assembled and arranged according to the needs of welding, positioning and clamping of different vehicle body components. Usually, a car body part needs multiple parts, and they are arranged in different ways, so that they can be assembled on a common steel platform to form a positioning and clamping tool for car body parts. Its assembly and positioning method is as follows:
[0037] 1. If Figure 8 As shown, the catch 31 of the positioning plate 3 is assembled backwards, and is fixed on the front of the fixed vertical plate 15 of the seat body 1 with bolts, and is used for the positioning of the side of the longer positioned beam 100 of the vehicle body parts. The right-angled plate 41 of the moving plate 4 is assembled downwards, and the two directions of the positioned beam 100 and the steel platform plane and the positioning plate 3...

The invention relates to a multi-functional positioning and clamping device for assembling railway freight carcomponents. The multi-functional positioning and clamping device for assembling the railway freight car components comprises a seat body, a supporting block, a positioning plate, a movable plate, a pin, a first screw and a second screw; the rear end of the seat body is provided with the supporting block, and the front end of the seat body is provided with the positioning plate; the movable plate is flexibly connected with the seat body through the pin. The first screw and the second screw are arranged on the movable plate. Due to the different positions of the assembling movable plate and the positioning plate, the multi-functionalpositioning and clamping device for assembling the railway freight car components has many functions such as positioning and clamping. The assembling and welding tooling of multiple car components can be made without using other accessories. The manufacturing is simple, the accessories are employed universally, and the maintenance is easy. The multi-functional positioning and clamping device for assembling the railway freight car components can be widely used in the assembling and welding of the railway freight car components, and is especially suitable for being applied in the flexible tooling of the assembling and welding components of a single car and a small-lot car group.
Description
technical field [0001] The invention relates to a railway wagon component, in particular to a railway wagon component assembly multipurpose positioning clamping device used in the assembly of the side wall and the end wall of the railway wagon. Background technique [0002] In the manufacture of the car body of railway freight cars, its parts such as side walls and end walls are welded parts of plates and beams, which are assembled and welded in assembled tires by multiple steel plates and various steel beams that have been blanked. Now mass-produced truck parts generally need to be equipped with special assembly welding tires to complete the positioning of each part, and weld them into one after clamping. However, when trial-manufacturing new truck parts or carrying out small-batch production, it is very uneconomical to manufacture special welded tires, and the manufacture of special welded tires requires professional design and manufacture, with a large workload and long t...
