Clamping device of frame longitudinal beam

Abstract

The invention discloses a clamping device of a frame longitudinal beam. The clamping device comprises a fixed seat, two side clamping mechanisms and a pressing mechanism, wherein two locating blocks used for supporting the longitudinal beam are arranged on the upper surface of the fixed seat; the pressing mechanism comprises a first cylinder and two pressing parts; the pressing parts comprise connecting rods and inverted-L-shaped pressing rods; the two ends of the connecting rods are separately hinged to a piston rod of the first cylinder and the pressing rods; the pressing rods are arranged on the inner sides of the locating blocks; the lower end parts of the pressing rods are hinged to the fixed seat; pressing blocks are arranged on the outer side surfaces and the bottoms of the upper ends of the pressing rods; the side clamping mechanisms are separately arranged on the two sides of the fixed seat, and comprise second cylinders, first connecting rods, second connecting rods and working rods; the second cylinders are hinged to the fixed seat; one ends of the first connecting rods are hinged to the fixed seat; the other ends of the first connecting rods are separately hinged to theend parts of the second connecting rods and piston rods of the second cylinders; the other end parts of the second connecting rods are hinged to the lower end parts of the working rods; clamping blocks are arranged on the inner side surfaces of the upper ends of the working rods; and the working rods are hinged to the fixed seat. According to the clamping device, sufficient clamping force can beprovided, and the longitudinal beam can be smoothly clamped.

Description

technical field [0001] The invention relates to the technical field of automobile processing equipment, in particular to a clamping device for a longitudinal beam of a vehicle frame. Background technique [0002] In the manufacturing process of the frame, especially the welding process, it is necessary to use tooling to clamp and position the frame longitudinal beam, so that the processing process can be carried out smoothly. The current mainstream clamping device has some deficiencies in structural design. A fixed positioning block is arranged on the outer end of the longitudinal beam placed on the device, and the fixing is completed by only clamping the inner end of the longitudinal beam. However, the structure of the longitudinal beam itself is a slender structure, and this structure is prone to large dimensional deviations during the stamping and welding processes of the parts. During the welding process of the longitudinal beam, the dimensional deviation caused by the ...

However, the structure of the longitudinal beam itself is a slender structure, which is prone to large dimensional deviations during the stamping and welding processes of the parts

During the welding process of the longitudinal beam, the dimensional deviation caused by the previous process often causes the longitudinal beam to be unable to be clamped smoothly on the tooling of the next process, which seriously slows down the production progress and reduces its output
