Embodiment Construction

[0023] like figure 1 , figure 2 , image 3 , Figure 4 As shown, the automatic side wall processing tooling of the present invention includes a sliding base 1, an acute angle pressing mechanism 2, an obtuse angle pressing mechanism 3, a vertical rotary pressing mechanism 4, and a hydraulic drive system 5, and the sliding base is connected with a multi-angle pressing mechanism , The hydraulic drive system controls the expansion and contraction of the sliding base, thereby controlling the multi-angle pressing mechanism to move away from or approach the workpiece. At the same time, the hydraulic drive system also controls the rotation angle of the multi-angle pressing mechanism, so as to realize the pressing of different workpieces. The hydraulic drive system adopts two-way solenoid valve 501 and PLC integrated control, and different control programs are compiled according to different workpieces to be processed, and different hydraulic cylinders are driven to feed in order to...

Abstract

An automatic fixture for machining large parts of rail vehicles is characterized by comprising a sliding base, a multi-angle pressing mechanism, and a hydraulic drive system. The sliding base is connected with the multi-angle pressing mechanism. The hydraulic drive system controls telescoping of the sliding base and accordingly controls the multi-angle pressing mechanism to leave or get close to a work piece. Meanwhile, the hydraulic drive system also controls rotation angle of the multi-angle pressing mechanism, so that different work pieces are pressed. The universal sliding base, the multi-angle pressing mechanism, the hydraulic drive system and a PLC are under integrated control, the fixture for machining the different large parts such as sidewalls, floors, chassis, roofs and edge beams in aluminum alloy vehicle bodies is automatically clamped, machining assistance time for a numeric control machine tool is reduced, production efficiency is improved, and the automatic fixture can be highly universal and automated in the field of fixtures for manufacturing the large parts of rail vehicles.

Description

technical field [0001] The invention discloses an automatic tooling scheme for processing large parts of an EMU, and belongs to the technical field of rail passenger car manufacturing. Background technique [0002] The traditional tooling scheme for processing large parts of aluminum alloy car body is: adopt general tooling, combine simple pressing plate, pressing screw, screw jack, etc., and use the principle of balance pressing to compress the workpiece, and the auxiliary processing time is too long , the production efficiency is extremely low. Contents of the invention [0003] The object of the present invention is to disclose a large part tooling of an aluminum alloy car body, which realizes the side wall, floor, underframe, vehicle The automatic clamping of tooling for processing different large parts such as roof and side beams is aimed at reducing the auxiliary time of CNC machine tool processing and improving production efficiency. [0004] In order to achieve t...
