Problems solved by technology

At present, the ring gear is turned over by a driving sling. In the actual operation process, due to the large diameter of the ring gear, the stability of the ring gear cannot be well controlled during the hoisting process of the driving sling, which inevitably causes the There will be different degrees of collision and damage to the ring, and it will become a serious waste product. In addition, the gear chamfering is manually operated, and the ring gear is placed on the ground. One side is chamfered, and then the other side of the gear is chamfered by turning over by driving. This process is labor-intensive and low in efficiency, and there is also a risk of collision with the ring gear.

Abstract

The invention discloses a slewing bearing gear chamfering and turning-over device which mainly consists of a stand part, a workpiece clamping and slewing part, a workpiece lifting part and a rotating workbench. The slewing bearing gear chamfering and turning-over device can be used for turning-over a variety of gear rings, so that the collision and the damage caused in the operation process are reduced, the work safety and the production efficiency are improved, and particularly the labor intensity of operators is reduced in the chamfering process. The gear chamfering and turning-over device is wide in application, and can be used for chamfering and turning over a variety of gear rings.

Description

technical field [0001] The invention belongs to a machine tool auxiliary device, in particular to a gear chamfering turning device. Background technique [0002] Slewing bearings are widely used in construction machinery, such as tower cranes, excavators, truck cranes, pile drivers, and concrete pump trucks. There are many processes in the processing of the slewing bearing ring gear, including rough turning, semi-finishing turning, raceway quenching, finishing turning, gear machining, drilling, grinding, etc. According to different processing requirements, different Locating the datum, the replacement of the datum makes the ring gear need to turn over constantly. At present, the ring gear is turned over by a driving sling. In the actual operation process, due to the large diameter of the ring gear, the stability of the ring gear cannot be well controlled during the hoisting process of the driving sling, which inevitably causes the gear The ring will be collided and damaged...
