Abstract
The utility model provides a tail seat of a metal cutting lathe, and relates to the field of machining, in particular to the tail seat of the metal cutting lathe, aiming at solving the technical difficulty that the surface of a work piece to be machine is low in quality when the existing tail seat of the lathe is used for machining a fixed thimble or movable thimble-supported long and heavy work piece. The tail seat mainly comprises a tail seat body, a sleeve and a leading screw. The tail seat is characterized in that the sleeve is internally provided with a hollow shaft system with an internal taper hole. The internal taper hole of the hollow shaft system with the taper hole only needs to be provided with the fixed thimble-supported work piece when the tail seat is used for machining, so that the tail seat can be used for cutting at a high speed, the technical difficulty that the surface of the work piece to be machine is low in quality since the fixed thimble-supported work piece of the existing tail seat of the lathe is unsuited to rotate at the high speed and the rigidity of the movable thimble-supported work piece is bad is solved, the surface quality of the work piece to the machined is high, the machined work piece is heavy in weight and large in volume, and the non-ferrous metal work piece can be lathed by the lathe.
Description
Technical field
The utility model belongs to field of machining, specifically the tailstock on the metal turning lathe.
Background technology
At present, known tail stock mainly is made up of tailstock body, the sleeve of being with internal taper hole, screw mandrel etc.Can adorn live centre or dead center in the sleeve taper hole and be used for supporting long, heavy industry spare, its shortcoming is: the thimble supporting workpiece of 1. feigning death centering is correct, the short good rigidity of thimble emersion sleeve, but be not suitable for rotation at a high speed, therefore be unfavorable for the raising of workpiece to be machined surface quality; Though 2. adorning the live centre supporting workpiece can rotate at a high speed, but centering is subjected to factor affecting such as live centre running accuracy and thimble emersion sleeve long support rigidity difference, still be unfavorable for the raising of workpiece to be machined surface quality, be unfavorable for that especially some are not suitable for improving with the method for grinding the non-ferrous metal and heavy, the big workpiece of surface quality.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned shortcoming, and a kind of of providing needs to install dead center and get final product high-speed cutting, improves the metal turning lathe tailstock of workpiece to be machined surface quality.
Technical solution of the present utility model is: the metal turning lathe tailstock comprises tailstock body, sleeve, screw mandrel, it is characterized in that being equipped with in the barrel of tail stock hollow shafting of band internal taper hole.
The hollow shafting of the band internal taper hole described in the technical solution of the present utility model is made up of the hollow shaft of band internal taper hole and two routine cylinder roller bearing, plane thrust bearing and the adjustment nut of inner ring pore area tapering, the central shaft hole of hollow shaft is connected with screw mandrel, and the cylindrical of hollow shaft is connected with sleeve by bearing.
The utility model is when processing work, only need in the internal taper hole of the hollow shafting of being with internal taper hole, to load onto the dead center supporting workpiece, get final product the high-speed cutting workpiece, overcome original tail stock thimble supporting workpiece of feigning death and be not suitable at a high speed rotation, dress live centre supporting workpiece rigidity difference and the not high technical barrier of workpiece to be machined surface quality that causes; Simultaneously the utility model makes ask for something workpiece surface quality height, and Heavy Weight, bulky workpiece, and the non-ferrous metal workpiece is achieved with lathe and carries out turning processing.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is mainly by tailstock body 1, sleeve 4, the hollow shafting of band internal taper hole, screw mandrel 5 is formed, sleeve 4 is housed in tailstock body 1, sleeve 4 can advance or retreats with the rotation of screw mandrel 5, the hollow shafting of band internal taper hole is housed in sleeve 4, the hollow shafting of this band internal taper hole is by the hollow shaft 2 of band internal taper hole, the two routine cylinder roller bearing 3 and the plane thrust bearing of inner ring pore area tapering, and adjust nut and form, the central shaft hole of the hollow shaft 2 of band internal taper hole is connected with screw mandrel 5, the cylindrical of hollow shaft 2 is connected with sleeve 4 with the plane thrust bearing by cylinder roller bearing 3, cylinder roller bearing 3 is fixed on the cylindrical of hollow shaft 2 by adjusting nut, be similar in the whole sleeve 4 of packing into of high accuracy live centre, can den bohrkopf einsetzen on the internal taper hole of the hollow shaft of hollow shafting or instrument such as centre drill cut, perhaps loading onto dead center is used for supporting long, heavy industry spare, thereby the heavy duty that realization integrates feign death thimble or live centre supporting workpiece, the smooth turning lathe tailstock.
Claims (2)
1. a metal turning lathe tailstock comprises that tailstock body (1), sleeve (4), screw mandrel (5) is characterized in that: the hollow shafting that the band internal taper hole is housed in the barrel of tail stock (4).
2. according to the described metal turning lathe tailstock of claim, the hollow shafting that it is characterized in that described band internal taper hole is made up of the hollow shaft (2) of band internal taper hole and two routine cylinder roller bearing (3), plane thrust bearing and the adjustment nut of inner ring pore area tapering, the central shaft hole of hollow shaft (2) is connected with screw mandrel (5), and the cylindrical of hollow shaft (2) is connected with sleeve (4) by bearing.
