Abstract
The utility model relates to a lower chord female joint welding tool for a crane boom and belongs to the technical field of engineering machinery. The lower chord female joint welding tool comprises a base frame (1), wherein a lower chord front end lug (2) and a lower chord rear end lug (5) are arranged on the base frame (1); horizontal lower chord clamps (3) and cushion block bolts (4) are arranged between the lower chord front end lug (2) and the lower chord rear end lug (5). According to the lower chord female joint welding tool for the crane boom, the labor intensity of workers is greatly alleviated, the production efficiency is improved, and the quality of a final product can be guaranteed.
Description
Technical field
The utility model relates to a kind of crane arm lower boom female joint welding tooling, belongs to technical field of engineering machinery.
Background technology
Tower machine, i.e. " derrick crane ", claims again by " tower crane ", is a kind of crane gear for construction.In general tower machine comes to be divided into by functions: basis, tower body, jacking, turn round, hoist, the part such as counter-jib, crane arm, trolley, tower top, drivers' cab, luffing, crane arm is the part of the force of lifting heavy.At present crane arm lower boom production process is fixed by manually female joint being put to solid welding, so its dimensional accuracy is difficult to control, and can final product quality be exerted an influence, and labor strength is high, and production efficiency is low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of crane arm lower boom female joint welding tooling is provided, and the labour intensity that it greatly reduces workman, has improved production efficiency, is conducive to guarantee final product quality.
The purpose of this utility model is achieved in that a kind of crane arm lower boom female joint welding tooling, it comprises underframe, on described underframe, be provided with lower boom front end ear seat and lower boom rear end ear seat, between described lower boom front end ear seat and lower boom rear end ear seat, be provided with the horizontal clamping of lower edge and cushion block bolt.
The horizontal clamping of described lower edge and cushion block bolt have two groups, and described two groups of horizontal clampings of lower edge and cushion block bolt are symmetrically arranged.
Compared with prior art, the utlity model has following beneficial effect:
A kind of crane arm lower boom of the utility model female joint welding tooling, the labour intensity that it greatly reduces workman, has improved production efficiency, is conducive to guarantee final product quality.
