Embodiment Construction

[0010] The fixed fixture has a fixed curved plate 4 on one end of the base 3, and a movable curved plate 2 on the other end. Move, clamp or release the workpiece. The bent plates at both ends of the fixed tooling can only clamp or loosen the workpiece, but cannot turn the workpiece over, let alone perform other processing operations such as drilling. In the present invention, a left rotating disc 8 and a right rotating disc 10 are arranged at both ends of the base 3, the outer central optical axis of the left rotating disc 8 passes through the shaft hole of the bearing seat 7, and can slide axially relative to the bearing seat 7, and the bearing seat 7 It is fixedly connected with the left support frame 6, and the left support frame 6 is fixed on the left end of the base 3; a hydraulic cylinder 5 is connected to the outside of the left rotary disc, and the hydraulic cylinder 5 can drive the left rotary disc 8 to move forward and backward through the connecting rod, and the wor...

Abstract

The invention discloses a rotary jointed tire of a standard joint of a stacker crane which includes a base and a left rotating disc and a right rotating disc arranged at the two ends of the base; the left rotating disc is connected on the base by a bearing seat and a left supporting frame; the outer side of the left rotating disc is provided with a hydraulic cylinder and a hydraulic transmission mechanism that are horizontally impelled; the outer side of the right rotating disc is provided with a rotating supporter and a reducer driven by a motor; the right rotating disc is connected on the base by the rotating supporter and a right supporting frame. The rotary jointed tire of a standard joint of a stacker crane can lead a workpiece to rotate, can stop at any position, thus reducing the welding difficulty and ensuring the welding quality. Simultaneously, hydraulic transmission is adopted by the invention to draw the left rotating disc to move front and back and lead a jointed workpiece to enter and go out of a frock; compared with the screw rod transmission used by an old frock, the rotary jointed tire has the advantages that: working intensity is low, the moving speed is fast and the production efficiency is improved.

Description

1. Technical field [0001] The invention relates to a supporting device for the production of a standard section of a tower crane, in particular to a tooling fixture particularly suitable for the production of an H-type standard section of a tower crane. 2. Background technology [0002] With the development of the construction market, the scale and tonnage of tower cranes continue to increase, and ordinary standard sections can no longer meet market needs. H-type standard section is popular among users because of its simple structure and convenient installation. The splicing production of the existing H-shaped standard joints all use fixed splicing tooling. The fixed tooling has a fixed curved plate on one end of a base plane and a movable curved plate on the other end. The movable curved plate is adjusted by the rotation of the screw. position, jam or unload the workpiece. During work, the parts that need to be welded are hoisted into the tooling with a crane, and after s...
