Clamp for assembling and welding stand column of lift car

Abstract

The invention provides a clamp for assembling and welding a stand column of a lift car, and relates to the field of clamps. The clamp comprises a rack, wherein the rack comprises two longitudinal beams which are arranged in parallel. According to the clamp, the shape-position tolerance between a limiting block and a body is ensured through a limiting device, the welding quality is guaranteed, andthe operation efficiency is improved; a shaft sleeve is arranged in the limiting device, and the lower end face of a main cross beam is fastened at the lower end of the shaft sleeve and meanwhile abuts against a limiting shaft to achieve the purpose of positioning the limiting shaft; a lower limiting block is arranged on the lower end surface of the main cross beam, so that the stability of a mainshaft is increased; an upper limiting block of the main shaft is provided with a kidney-shaped hole and a notch, the four-side rectangular section of the main shaft can freely slide in the kidney-shaped hole, and when the main shaft enters the notch, the main shaft can only slide left and right to limit rotation of the main shaft, the notch is formed in the upper end of a main positioning block and is matched with the lower section of the main shaft, so that it is guaranteed that the main limiting block is consistent with the main shaft in a rotating mode; and circular angles are formed in the upper end surface and the side surface of the main positioning block, so that the main limiting block is prevented from being interfered with the inner side of a stand column body when the main limiting block rotates.

Description

technical field [0001] The invention relates to the field of fixtures, in particular to a fixture for tailor-welding of uprights of car transport vehicles. Background technique [0002] As a model added to the new GB1589, the central axle train has been fully demonstrated, and its length, economy, function and safety advantages are very obvious, and it has gradually become the mainstream model in the car transport industry. The force and limit of the upper platform of the center-mounted axle car transporter are guaranteed by the column during the lifting process, and the stability of the upper platform is also guaranteed by the column during the operation of the vehicle. The slider is matched with the column, and the slider slides on the inside of the column. Therefore, during the tailor welding process of the column, it is necessary to ensure that the verticality between the limit plate and the body is ±1mm, and the dimensional error of the column is ±1mm. If the above tol...

AI Technical Summary

Problems solved by technology

If the above tolerance is exceeded during the tailor welding process of the column, the slider will be stuck when sliding inside the body, resulting in the failure of the upper platform to lift normally
