Abstract
The invention discloses a main spindle box for a machine tool. The front end of a main spindle in the main spindle box is positioned and supported by a pair of bearings and pre-tightened by a lock nut; the back end of the main spindle is provided with an auxiliary bearing for supporting; a motor drives the main spindle to rotate through a worm couple; and the tail of the main spindle is provided with a rotary oil cylinder which can clamp and release a workpiece on the end face of the main spindle through a pull rod connected with the rotary oil cylinder. In a structure special for the main spindle box of the machine tool, the motor is directly connected with the main spindle box, so that the occupied space of the main spindle box is small, the rotating speed of the main spindle is controlled in a variable frequency way through the motor and a process rotating speed is convenient to adjust.
Description
Technical field
The invention belongs to a kind of lathe interior arrangement, particularly a kind of structure of special purpose machine tool main spindle box.
Background technology
The existing machine tool main spindle box generally all is installed separately with motor, and motor power passes to main spindle box by conveyer belt, reaches process speed by hand gear, and floor space is bigger, must stop during adjusting process speed, has a lot of inconvenience in processing.
Summary of the invention
The lathe headstock that provides a kind of floor space little is provided technical problem solved by the invention.
The technical solution that realizes the object of the invention is: a kind of lathe headstock comprises main shaft casing, case lid, motor, worm screw gland, oil cylinder flange, terminal pad, axle sleeve, worm gear, distance piece, the big end cap of main shaft, pull bar, main shaft, the little end cap of main shaft, worm screw, worm screw end cap, principal shaft locking nut, worm gear locking nut, rotary oil cylinder;
Main shaft is installed on the main shaft casing by a pair of taper roll bearing, and by principal shaft locking nut pretension, the position that the main shaft tank ends contacts with main shaft is provided for the big end cap of main shaft and the little end cap of main shaft of dust seal, in the little end caps of main shaft the bearing that main shaft is carried out supplemental support is set, the main shaft afterbody is provided with terminal pad, rotary oil cylinder is connected with terminal pad by the oil cylinder flange, the pull bar that is positioned at the alignment of shafts links to each other with rotary oil cylinder, rotary oil cylinder clamps the workpiece on the main shaft end face by pull bar and loosens, the middle part of main shaft is provided with worm gear, this worm gear is by worm gear locking nut locking, and adjusts the center line of itself and worm screw by distance piece;
Worm screw is installed in the bottom of main shaft casing by a pair of taper roll bearing, and realizes axial location by the worm screw gland and the worm screw end cap that are arranged on the worm screw two ends, and motor is installed on the main shaft casing, and its power output shaft is connected with worm screw, drives its rotation.
The present invention compared with prior art, its remarkable advantage: the present invention is a kind of special purpose machine tool main spindle box because motor and main spindle box are direct-connected, it is little to take up room, its speed of mainshaft is controlled by motor frequency conversion, makes things convenient for the adjustment of technology rotating speed.
Below in conjunction with accompanying drawing the present invention is described in further detail.
