End-to-end type modular fixture and reversing machine comprising same

Abstract

The invention discloses an end-to-end type modular fixture and a reversing machine comprising the same. The end-to-end type modular fixture comprises a front clamping device and a tail clamping device, wherein the front clamping device consists of a rotary connecting disc, a crossbeam and supporting lugs; the rotary connecting disc is connected with the middle part of the crossbeam; two groups of supporting lugs are provided and are symmetrically arranged at the two ends of the crossbeam; the tail clamping device consists of a wheel type frame, regulating screws and a pedestal; the pedestal is arranged at the bottom of the wheel type frame; the regulating screws are arranged on the rest three surfaces of the wheel type frame; the reversing machine comprises a driving device, a driven device and a control system; the driving device consists of the tail clamping device, an anti-tipping wheel, supporting idler wheels, a driving motor and a supporting base; the driven device consists of the front clamping device, a rotary support, a mobile base and a driving screw. The end-to-end type modular fixture disclosed by the invention has the beneficial effects of realizing reversal replacement of a large part and being high in work efficiency, simple to operate, hard to roll over, high in safety efficiency and low in dependence on other auxiliary equipment.

Description

technical field [0001] The invention relates to a combination fixture, in particular to a head-to-tail combination fixture and a turning machine with the fixture. Background technique [0002] At present, the turntables of medium and large tonnage crawler cranes are large in size and heavy in weight. When the turntable components are assembled, the turntables are generally supported by load-bearing horse legs for stall-style assembly. Among them, during the assembly of the slewing bearing and the adjustment of the meshing clearance of the gears of the slewing mechanism, due to the lack of a suitable flip fixture, the turntable cannot be turned over. It is necessary to assemble the slewing support and adjust the meshing clearance from the bottom of the turntable, and the workers must operate at the bottom of the turntable. , low work efficiency, poor operating comfort and potential safety hazards.
