Unblocked Long Roller Jaw Lathe Steady Frame

Abstract

The invention provides a free-flowing center frame of a lathe with long roller jaws. The frame body of the center frame is an open frame body that ensures sufficient rigidity and is open to the direction of the tool rest of the lathe. They are arranged on the center frame body, one of which is set directly below the center line of the lathe, which can ensure the balanced stress of the slender shaft processing parts. When turning slender shaft workpieces, it can be turned continuously at the center frame. Unlike the general-purpose center frame, when turning slender shaft workpieces, it is necessary to stop at the center frame due to the obstruction of the center frame. After processing one side of the center frame Afterwards, the steady rest is moved and the other side, which is not machined, is turned. Turning of slender shaft workpieces has high work efficiency. The long roller claw mechanism is adopted to lengthen the support length of the slender shaft workpiece, which greatly increases the rigidity of the slender shaft workpiece and improves the turning quality of the slender shaft workpiece.

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...

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
