Novel flexible overturning fixture for multiple vehicle frames

Abstract

The invention relates to a novel flexible overturning fixture for multiple vehicle frames. The novel flexible overturning fixture is characterized in that a support and a bearing seat are fixedly connected to an automatic overturning device bracket; one end of an overturning shaft is connected with a drive motor through the support and the bearing seat, and the other end of the overturning shaft is connected with an overturning framework; a follow-up bearing seat, a follow-up support and a back stop wheel are fixed on the follow-up bracket of an automatic follow-up overturning device; a follow-up rotary shaft is connected with the overturning framework; propping mechanisms and supporting devices are fixed on the overturning framework; the supporting devices are uniformly and symmetrically arranged on the overturning framework; one end of each supporting device is connected with the overturning framework, and the other end of each supporting device is contacted with the beam of a vehicle frame; the propping mechanisms are arranged on the overturning framework in a left and right intersection mode; each propping mechanism comprises a pressure head, a propping support, a bush, a lead screw and a limit nut; one end of the propping support is fixed on the overturning framework, and the bush is arranged at the other end of the propping support; the lead screw is connected to the bush; one end of the lead screw is connected with the pressure head; and the other end of the lead screw is connected with the limit nut. Through using the novel flexible overturning fixture, the full automation of the multiple vehicle frames in the welding process is realized, the labor intensity of workers is reduced, the accurate and reliable overturning angle is achieved, and the reliability and safety of the overturning device are improved.

Description

technical field [0001] The invention relates to a novel multi-vehicle frame flexible flip fixture, which belongs to the field of tooling mechanization. Background technique [0002] Existing technology mainly contains the automatic turning over of artificial overturning, semiautomatic overturning and single variety vehicle. This has always been a weak link in the production process. [0003] The main defect of the existing automatic flip fixture technology is poor reliability. When the same production line produces multiple frames, the force on the flip device is unbalanced due to the different positions of the center of gravity of the frame, and the phenomenon of jamming or even damage to the equipment occurs during the flip process. Doesn't make auto-flip work reliably. Contents of the invention [0004] The purpose of the present invention is to provide a new type of multi-vehicle frame flexible flip fixture, which realizes the full automation of the multi-vehicle fra...
