Steel pipe axial positioning device for drilling machine and fixture table

Abstract

The invention relates to the technical field of mechanical manufacturing, in particular to a steel pipe axial positioning device and a fixture table for a drilling machine, comprising: a fixture table, a chuck and a ratchet; the chuck is arranged on the upper part of the fixture table, and the chuck and the fixture table pass through The bearing is connected; the ratchet wheel is arranged at one end of the chuck, and the ratchet wheel and the chuck are connected by a pin-stud inlaid manner; the pawl is arranged on one side of the fixture table, and the pawl and the fixture table are connected by a rotating shaft; The crank handle is arranged at one end of the chuck, and the crank handle and the chuck are connected by screw connection. Through the structural improvement, it has the advantages of reasonable clamping structure setting to prevent the workpiece from slipping, rotating and tilting under force, the axial positioning processing method increases the diversification of processing functions, the structure connection is simple and the operation process is convenient, etc., so as to effectively solve the problem. The problems and deficiencies existing in the existing devices are solved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a steel pipe axial positioning device and a fixture table for a drilling machine. Background technique [0002] The fixture table of the drilling machine is a machine tool fixture used to fix the workpiece so that the tool can drill or ream the hole on the workpiece. The problem of rotation and tilt occurs during the process, so as to ensure the position accuracy of the processed hole. This device is mostly used in the processing of metal workpieces such as iron plates and steel pipes. [0003] However, the clamping table of the drilling machine currently used has imperfect workpiece clamping methods, which lead to slippage, rotation, and tilting of the workpiece during the drilling process. The single use method limits the processing of circular workpieces, and the unreasonable structure setting leads to cumbersome operations during the use process. , The circu...

Problems solved by technology

[0005] The object of the present invention is to provide a steel pipe axial positioning device and a fixture table for drilling machines, so as to solve the problem of slippage, rotation, and inclination during the drilling process of the workpiece due to the imperfect clamping method of the workpiece proposed in the above background technology, and the use method is single. The processing of circular workpieces is restricted, the unreasonable structure setting leads to cumbersome operation in the use process, and the circular workpieces have no problems and deficiencies in the function of axial positioning.
