A device for measuring the hole position of a large turntable bearing

Abstract

The invention discloses a large rotating disc bearing hole position accuracy measurement device. The large rotating disc bearing hole true position measurement device comprises a placement device, a fixed housing, a pedestal, a connection rod, a rear support, a regulating block, a looseness regulator, a lifting rod, a measurement gauge, a fixed rack, an adjustment head and a measurement rod. The placement device is installed on the fixed housing. The bottom of the fixed housing is perpendicularly connected to the top of the left end of the pedestal. The bottom of the rear support is perpendicularly connected to the top of the right end of the pedestal. Two ends of the connection rod are fixed between the internal of the fixed housing and the internal of the rear support. The bottom of theregulating block is fixed above the rear support. The bottom of the lifting rod is movably connected to the internal of the regulating block and the fixed support is installed on the top of the lifting rod. The placement device can perform fast regulation placement according to a practical size of the rotating disc bearing, can increase convenience of usage and can save the placement regulation time during usage.

Description

technical field [0001] The invention is a device for measuring the position degree of a large-scale turntable bearing hole, which belongs to the field of position degree measurement devices for a large-scale turntable bearing hole. Background technique [0002] At present, there are many instruments for measuring the position in China, but it is more difficult to measure the position of the large-scale slewing bearing hole. For the large-scale slewing bearing ring, it will continue to be machined after drilling, and the ring will be deformed, especially for thin-walled bearings. The deformation is even larger, and the hole position will also change. [0003] The existing technology is not perfect, and the existing measuring device for the position degree of the slewing bearing hole cannot be adjusted according to the measured size of the slewing bearing in a position fixing manner, which reduces the convenience of use. Contents of the invention [0004] Aiming at the defi...
