Positioning mechanism for machining pipes

Abstract

The invention discloses a positioning mechanism for machining pipes. A circular-hole positioning groove is formed in the plate face of one side of a circular-plate base, and a through hole communicated with the positioning groove is also formed in the base; an output shaft of a motor runs through the through holes to be detachably connected with an installing shell sleeve, and the installing shellsleeve is contained in the positioning groove; one axial end of a to-be-machined pipe is detachably fixed on the installing shell sleeve; multiple sliding grooves are formed in the plate face of thepositioning groove formed in the base, and are radially distributed with the positioning groove as a base point at equal intervals, one ends of limiting shafts in the axial direction extend into the sliding grooves, the limiting shafts are driven by a driving mechanism to slidingly move in the extending directions of the sliding grooves, rollers sleeve the limiting shafts, the inner walls of the rollers are in rolling connection with the outer walls of the limiting shafts, and the outer walls of the rollers are in frictional contact with the outer wall of the to-be-machined pipe. According tothe positioning mechanism for the machining pipes, it can be avoided that the to-be-machined pipe conducts radial run-out in the rotating process.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a positioning mechanism for processing pipes. Background technique [0002] The clamping device is a commonly used device in various mechanical processing processes. It is used to fix the materials or parts to be processed to ensure that they will not move and deviate during the processing, and to avoid the deviation of the items to be processed from affecting the operation. For cylindrical pipes, it is easy to roll during production, processing and cutting, and it is necessary to fix them before subsequent work. The existing pipe fixing devices usually use chains or pipe wrench for fixing, but when the pipe needs to be stretched or a large force is applied, it is easy to cause the phenomenon of pipe detachment, displacement, etc., and the pipe cannot be fixed stably and reliably, and the pipe Jumping will occur during the rotation, which will affect the cutting, g...
