Horizontal and longitudinal locking type valve drilling device

Abstract

The invention discloses a horizontal and longitudinal locking type valve drilling device which comprises an operation table, a clamping mechanism, a stretchable mechanism, a driving motor, a driving shaft and a drill bit; a connecting block is arranged at the upper end of the drill bit, the longitudinal cross section of the connecting block is of a mountain-shaped structure, an annular groove is formed in the middle of the upper end of the connecting block, a connecting column is arranged in the middle of the annular groove, and an external thread is arranged on the upper half part of the connecting column; a penetration groove is formed in the lower end of the driving shaft, an internal threaded hole is formed in the upper half part of the penetration groove, the annular groove is connected to the lower end of the driving shaft in a sleeving manner, the connecting column is in threaded connection into the penetration groove, and the connecting block and the driving shaft are providedwith threaded holes corresponding in position; and screws are connected to the threaded holes and are sequentially connected with the connecting block and the driving shaft in a penetrating manner. According to the horizontal and longitudinal locking type valve drilling device, through screw-thread fit of the connecting column and the penetration groove and the screw fixation of the connecting block and the driving shaft, longitudinal l and horizontal fixed connection of the drill bit and the driving shaft is guaranteed.

Description

technical field [0001] The invention relates to a horizontal and vertical locking valve drilling device. Background technique [0002] At present, during the manufacture and maintenance of valves, it is generally necessary to drill holes for the valves. The existing valve drilling devices generally drive the drill bit to rotate and move up and down through the driving device, but the drill bit and the valve in the existing valve drilling device The rotating shafts are all fixedly connected, and it is very inconvenient to replace the drill bit after a period of use. The present invention provides a drill bit movable installation structure, which is convenient for installation and disassembly while ensuring the stability of the connection. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned prior art, the problem to be solved by the present invention is: to provide a horizontal and vertical locking valve drilling device with stable connection...
