Drilling device and drilling method for slewing bearing

Abstract

The invention discloses a drilling device and a drilling method for rotary disc type bearing. The drilling device comprises a base, a base plate and a mounting plate, wherein the base plate is weldedto the top of the base, and a through hole is formed in the middle end of the interior of the base plate; and a first motor is installed at the middle end of the top of the base, a longitudinally-arranged bearing rod is fixedly arranged at the top of the first motor, and the top of the bearing rod penetrates upwards from the interior of the through hole. A longitudinally-arranged first electric telescopic column is arranged on one side of the bottom of the mounting plate, the top of the first electric telescopic column is fixedly connected with a clamping buckle, and one side of the clamping buckle is fixedly connected with the outer bottom end of the bearing rod. A fixing frame is mounted at one end of the bottom of the mounting plate, and three sets of drill bits are uniformly mounted atthe bottom of the fixing frame. The drilling device is convenient and rapid to use, can be processed according to different disc-type bearings, and can adapt to disc-type bearings with different sizes, the drilling disc type bearing is convenient and rapid to mount, high in working efficiency and cleaner and sanitary.

Description

technical field [0001] The invention relates to a drilling device, in particular to a drilling device and a drilling method for a turntable bearing, belonging to the field of bearing processing applications. Background technique [0002] The slewing bearing is a large bearing with a special structure that can bear comprehensive loads such as large axial loads, radial loads, and overturning moments at the same time, and integrates multiple functions such as support, rotation, transmission, and fixation. In general, the slewing bearings themselves have installation holes, lubricating oil and sealing devices, which can meet the different needs of various hosts working under various working conditions, and are widely used in lifting and transportation machinery, mining machines, construction machinery, etc. On large slewing devices such as construction machinery, port machinery, wind power generation, medical equipment, radar and missile launchers, slewing bearings often need to...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a drilling device and drilling method for slewing bearings, which can solve the problem that the existing drilling devices for slewing bearings have a simple structure and can only be drilled individually, and direct water cooling is used in the drilling. In this way, the processed bearings are not clean, and it is troublesome to clean up later.

The working efficiency of drilling is low, it cannot be adjusted quickly according to actual needs, the operation is troublesome, and it cannot adapt to the technical problems of disc bearings of different sizes
