Heavy-duty horizontal lathe tailstock moving device

Abstract

The invention discloses a heavy-duty horizontal lathe tailstock moving device, which includes a slide rail. The slide rail is connected to a slide seat through a T-shaped slide groove provided inside. The slide seat is provided with a symmetrical structure on one side close to the slide rail. There are two sets of distributed L tightening handles. One end of the electric telescopic rod is connected to the side of the slide rail close to the slide base. The other end of the electric telescopic rod is connected to the slide base. The outer side of the slide rail is provided with a control switch, the upper side of the I-shaped support plate is equipped with an outer sleeve, and the electric telescopic rod telescopically pushes the connected slide seat to move on the slide rail, and the L tightening handle conveniently fixes the slide seat and the slide rail relative to each other to make the tail The seat is easy to move and fix on the bed, which can avoid sliding when tightening. The arc-shaped anti-slip block and the annular groove provided on the turntable can play a good tightening effect and can avoid sliding when tightening. There is shaking and instability.

Description

technical field [0001] The invention relates to the technical field of heavy-duty horizontal lathes, in particular to a tailstock moving device for heavy-duty horizontal lathes. Background technique [0002] With the rapid development of our country's national economy, there is an increasing demand for heavy-duty machine tools. In heavy-duty CNC horizontal lathes, the tailstock mainly plays the role of tightening and supporting the workpiece, and according to the length of the workpiece processed by the machine tool, the moving tailstock The seat system realizes the supporting ability of the workpiece. For the heavy-duty horizontal lathe, the traditional tailstock structure has insufficient torque transmission. The patent with the publication number 201620307779.6 discloses a heavy-duty horizontal lathe tailstock moving device. The end of the gear shaft is connected to the power output shaft of the reduction motor through the first flat key, and the gear shaft meshes with th...

[0002] With the rapid development of our country's national economy, there is an increasing demand for heavy-duty machine tools. In heavy-duty CNC horizontal lathes, the tailstock mainly plays the role of tightening and supporting the workpiece, and according to the length of the workpiece processed by the machine tool, the moving tailstock The seat system realizes the supporting ability of the workpiece. For the heavy-duty horizontal lathe, the traditional tailstock structure has insufficient torque transmission. The patent with the publication number 201620307779.6 discloses a heavy-duty horizontal lathe tailstock moving device. The end of the gear shaft is connected to the power output shaft of the reduction motor through the first flat key, and the gear shaft meshes with the first gear on the transition shaft. A gear meshes with the second gear on the worm, and the two ends of the worm are respectively installed on the tailstock through the second cylindrical roller bearing and the thrust cylindrical roller bearing. The outer end of the worm is correspondingly provided with a flange, but the above patents are using During the process, the transmission torque is insufficient, and the movement and fixation of the tailstock on the bed are inconvenient, which cannot play a good role in jacking up.
