Clamping device of frame longitudinal beam

Abstract

The invention discloses a clamping device for a longitudinal beam of a vehicle frame, which comprises a fixing seat, two side clamping mechanisms and a pressing mechanism; two positioning blocks for supporting the longitudinal beam are arranged on the upper surface of the fixing seat; the pressing mechanism It includes the first cylinder and two pressure pieces; the pressure piece includes a connecting rod and an inverted L-shaped pressure rod, and the two ends of the connecting rod are respectively hinged to the piston rod and pressure rod of the first cylinder; the pressure rod is set inside the positioning block and the lower end is hinged to the fixed There are pressure blocks on the outer side of the pressure rod and the bottom of the upper end; the side clamping mechanisms are respectively arranged on both sides of the fixed seat, including the second cylinder, the first connecting rod, the second connecting rod and the working rod; the second cylinder is hinged on the fixed seat; one end of the first connecting rod is hinged to the fixed seat, and the other end is respectively hinged to the end of the second connecting rod and the piston rod of the second cylinder; the other end of the second connecting rod is hinged to the lower end of the working rod; the inner surface of the upper end of the working rod is set There is a clamping block, and the working rod is hinged to the fixed seat. The device can provide sufficient clamping force, and can also make the stringer clamp smoothly.

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
