Problems solved by technology

[0003] Aiming at the problems that the center frame of most existing lathes can not carry out the turning process continuously, the production efficiency is low, the center frame of a part of the open lathe, and the three claws can not exert force on the workpiece in a balanced manner, etc., the present invention provides a pair of three claws. The workpiece is evenly applied force, so that the turning process can be carried out continuously, and the production efficiency is high. The steady frame of the smooth long roller jaw lathe

Abstract

The invention provides an unblocked long roller claw lathe center rest. The center rest is an open-type rest which can ensure enough rigidity and opens toward a lathe saddle. Three long roller claw mechanisms are arranged on the center rest at an equal interval; one of the three long roller claw mechanisms is arranged under a central line of a lathe, which can ensure even stress on a slender shaft type work piece; during turning of the slender shaft type work piece, constant turning can be performed on the work piece on the center rest, unlike the common center rest, turning needs stopping due to block of the center rest during turning of the slender shaft type work piece on the center rest, after the work piece at one side of the center rest is machined, the center rest is moved, and turning of the work piece at the other side of the center rest is performed. The unblocked long roller claw lathe center rest has high working efficiency in turning of slender shaft type work pieces; through the long roller claw mechanisms, the support length of the slender shaft type work pieces is lengthened, the rigidity of the slender shaft type work pieces is greatly enhanced, and the turning quality of the slender shaft type work pieces is impoved.

Description

technical field [0001] The invention belongs to a machine tool auxiliary part, in particular to a smooth-flow long roller jaw lathe center frame. Background technique [0002] Lathes are the most commonly used important equipment in mechanical processing. When a slender shaft with a relatively large length and diameter is processed on a lathe, its rigidity is poor and it is easy to deform, and the processing accuracy is difficult to control. It is a difficulty and focus in lathe processing. It is usually necessary to use the lathe center frame to enhance its rigidity and reduce its deformation. Therefore, the structure and performance of the lathe center frame are very important. In most existing lathe center frames, the frame body is composed of upper and lower parts, which are fastened with screws to form a closed frame. The three jaws are arranged at intervals of 120o based on the jaws directly above the center of the lathe, and the workpiece is position. When the workp...
