Car frame longitudinal beam clamping supporting platform

Abstract

The invention discloses a car frame longitudinal beam clamping supporting platform. The car frame longitudinal beam clamping supporting platform comprises a base, a connecting rod is vertically welded to the bottom of the base, a supporting plate is connected to the end, away from the base, of a buffer spring, a fixing plate is fixedly connected to the end, away from the supporting plate, of a buffer device, a first connecting plate is fixedly connected to the side, away from the buffer device, of the fixing plate, the first connecting plate is movably connected with a quadrilateral hinge through rivets, a hydraulic pump is fixedly connected to the top of the first connecting plate, symmetric telescopic cylinders are vertically welded to the positions, at the two ends of the first connecting plate, of the top of the fixing plate, a second connecting plate is fixedly connected to the bottom of a telescopic plate, a sliding rail is arranged on the top of the telescopic plate, and a clamp is fixedly connected to the side, away from the sliding rail, of a sliding block. The platform is simple in structure, impact to the clamping supporting platform can be effectively buffered in the lifting process, and through the telescopic plate and the movable clamp, clamping supporting of car frame longitudinal beams with different size specifications can be achieved; the extremely high production efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile production equipment, in particular to an automobile frame longitudinal beam clamping support platform. Background technique [0002] Automobile frames are generally composed of longitudinal beams and cross beams. There are mainly two types of side beams and middle beams. The side beam frame consists of two longitudinal beams on both sides and several beams. Connect the longitudinal beams to the cross beams to form a strong rigid frame. Longitudinal beams are usually stamped from low-alloy steel plates, and the cross-sectional shape is generally groove-shaped, and some are made into Z-shaped or box-shaped. According to the different forms of automobiles and the requirements of structural layout, the longitudinal beams can be made curved in the horizontal plane or in the longitudinal plane, and have equal or non-equal sections.

AI Technical Summary

Problems solved by technology

[0003] During the production of automobiles, a series of processing is required on the frame longitudinal beams, such as drilling, welding, etc., and if the clamping is not ideal during the processing, stress deformation or hole spacing error will easily occur, which will affect the later assembly. It will bring difficulties and even produce defective products; and the frame will produce impact during the hoisting process, which will cause certain deformation of the support platform, and there will be shaking during the clamping process, resulting in drilling, welding, etc. There are deviations in processing, which is not conducive to the precise processing of frame longitudinal beams; at the same time, modern automobile production workshops require clamping and supporting frame longitudinal beams of different specifications, which requires the clamping support platform to be able to adapt to different sizes of longitudinal beams clamp support
