Description

Technical Field

[0001] The present invention relates to the technical field of vehicle body welding in rail transit, and specifically to a curved surface flexible workstation. Background Technique

[0002] Currently, vehicle models are diverse, with different widths, arcs, and overall appearances, resulting in completely different surface shapes of the roof skeletons. For such products, basically, there is a fixed fixture for each vehicle, and a small number of vehicle models with the same surface shape can share the fixture, but the number of such fixtures is still very large. When such fixtures are not working or the production volume decreases, the storage location poses a huge problem for the main engine factory.

[0003] Having a fixture for each vehicle actually ensures the stability of the quality of vehicle models. At present, factories are very careful about labor and investment. The same factory building area, worker operation, and equipment investment are all within the calculation. First of all, due to the limited factory building area, it is impossible to have a fixture for each vehicle when a new vehicle model is introduced. Therefore, there is an urgent need for a new type of fixture to meet the welding and clamping work of arbitrary curved surface parts. Summary of the Invention

[0004] The purpose of the present invention is to provide a curved surface flexible workstation to solve the problem that the existing fixtures cannot meet the welding and clamping work of arbitrary curved surface parts mentioned in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A curved surface flexible workstation includes a Z - direction handle control system, an X - direction handle control system, a Z - direction pallet, an X - direction unit mounting plate, a steel structure support, a Z - direction shaft fixed support, a Y - direction handle control system, a Y - direction fixed support, an X - direction shaft rotating mounting base plate, a Z - direction unit fixture, and an X - direction unit fixture. The Z - direction handle control system, the X - direction handle control system, and the Y - direction handle control system are installed on the steel structure support. The Z - direction handle control system is connected to the Z - direction shaft fixed support, and a Z - direction pallet and a Z - direction unit fixture are installed on the Z - direction shaft fixed support. The X - direction handle control system is connected to the X - direction unit mounting plate and the X - direction shaft rotating mounting base plate, and an X - direction unit fixture is installed on the X - direction unit mounting plate. The Y - direction handle control system is connected to the Y - direction fixed support;

[0006] The Z - direction unit fixture includes a quick clamp, a quick clamp mounting block, a unit mounting plate, a first surface block, a second surface block, a first connection block, and a second connection block. The lower part of the quick clamp is installed on the unit mounting plate through the quick clamp mounting block. The clamping end of the quick clamp is connected to the first connection block through the second connection block, and a second surface block is installed on the first connection block. The first surface block is installed on the unit mounting plate;

[0007] The X-direction unit fixture includes a handle, a connecting plate, a positioning sleeve, a ejector rod, and a profiled block. The handle is connected to the positioning sleeve through the connecting plate, and there are two connecting plates. The connecting plates are located on both sides of the handle and the positioning sleeve, and are movably connected to the handle and the positioning sleeve through pin shafts. The lower part of the handle is movably connected to one end of the ejector rod, and the other end of the ejector rod is provided with a profiled block.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: This curved surface flexible workstation is convenient and efficient to operate. By using the worm and worm gear technology, within a certain length range, the Z-axis moves axially, and the X and Y axes rotate axially to complete the final position of the fixture, enabling the welding and clamping process of parts with any curved surface to be realized. This fixture can clamp and weld various shapes. Brief Description of the Drawings
