Problems solved by technology

[0003] However, in some fields, turning processing still encounters some difficult problems, such as pipe / rod workpieces with a length-to-diameter ratio exceeding 10:1, because the pipe / rod workpiece is inevitably affected by gravity when clamping horizontally Bending occurs, which will lead to a decrease in the coaxiality of the workpiece, and problems such as large vibration and instability during processing
In this way, not only the processing quality of the workpiece is affected, but also the lathe used for processing will be affected by vibration, resulting in a decrease in accuracy
It can be seen that for how to process pipe / rod workpieces more stably, no good solution has been provided in the prior art

Abstract

The invention discloses an auxiliary clamping mechanism for tubular and rod workpieces. The auxiliary clamping mechanism comprises a base, at least two positioning mechanisms which are coaxially arranged and assembled on the base in a sliding manner, and a locking mechanism capable of fixing the positioning mechanisms and a conveying mechanism to the base. The auxiliary clamping mechanism has the beneficial effects that through a tool, auxiliary positioning clamping of tubular and rod workpieces can be achieved, the workpieces are prevented from bending and deforming due to gravity, and coaxiality is improved; and the machining precision is improved, and vibration generated by high-speed rotation can be prevented. In addition, the beneficial effects of being simple in structure, high in practicability and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to an auxiliary clamping mechanism for pipe and rod workpieces. Background technique [0002] Turning is a processing method for processing the outer edge of a rotary workpiece. It has the advantages of simple processing, convenient operation, good processing accuracy, and high degree of automation. It is the most basic and important processing method in the field of manufacturing. [0003] However, in some fields, turning processing still encounters some difficult problems, such as pipe / rod workpieces with a length-to-diameter ratio exceeding 10:1, because the pipe / rod workpiece is inevitably affected by gravity when clamping horizontally Bending occurs, which will lead to problems such as a decrease in the coaxiality of the workpiece, large vibration and instability during processing. As a result, not only the processing quality of the workpiece is affec...
