Abstract
The invention discloses a bidirectional machine tool spindle integrally provided with a clamping mechanism. The bidirectional machine tool spindle integrally provided with the clamping mechanism comprises a rotating shaft. The rotating shaft is connected with a front flange and a rear flange. A piston hole is formed between the front flange, the rear flange and a unit jacket. A piston pushing body which can horizontally move in the axial direction is arranged in the piston hole. The piston pushing body moves forwards so as to drive a pushing piece, and accordingly a connecting cylinder body and a chuck wedge core are driven to move, so that a four-claw sliding block is promoted to move outwards in the radial direction, and soft claws are loosened; the piston pushing body moves backwards so as to be separated from the pushing piece, a backward-pushing cylinder body, the connecting cylinder body and the chuck wedge core are driven by a disc spring to move backwards, the four-claw sliding block is promoted to move inwards in the radial direction, and thus a workpiece is clamped. According to the bidirectional machine tool spindle integrally provided with the clamping mechanism, the two ends of the workpiece can be machined at the same time through one-time clamping; in addition, the dimension of the machined workpiece is not limited, machining of a larger workpiece can be completed, and the effect that the workpiece clamping force is proper is guaranteed.
Description
Technical field
The present invention relates to a kind of machine tool chief axis, particularly the two-way machine tool chief axis of a kind of built-in clamping device.
Background technology
Existing machine tool chief axis, can only carry out unidirectional processing to one end of clamping workpiece, machines the rear tune processing other end, the workpiece of processing, and will certainly there is mismachining tolerance in its concentricity. thus, on market, there is the two-way machine tool chief axis of built-in clamping device. Chinese invention patent application publication No. CN103920892A discloses the two-way machine tool chief axis of a kind of built-in clamping device, as shown in Figure 1, comprise axis system, built-in clamping drive system, shift fork system, clamp executing agency, described built-in clamping drive system comprises main axle unit cover 1, closed type two-direction thrust bearing module 2, described rear bearing pivot flange 3 is fixedly connected with the rear end of main axle unit cover 1, and fore bearing pivot flange 4 is fixedly connected with the front end of main axle unit cover 1, rear bearing pivot flange 3, fore bearing pivot flange 4 form the main shaft bearing hole seat with a span with main axle unit cover 1, described closed type two-direction thrust bearing module 2 is arranged in the seat of main shaft bearing hole, and closed type two-direction thrust bearing module 2 can move back and forth in the seat of main shaft bearing hole, described shift fork system comprises thrusting plate 5, thrusting plate 5 is fixedly connected with closed type two-direction thrust bearing module 2, and thrusting plate 5 is fixedly connected with post-tensioning cylinder body 6 and post-tensioning pad 7, thrusting plate 5 is fixedly connected with by post-tensioning cylinder body 6 and post-tensioning pad 7. when use, Compressed Gas enters in the seat of main shaft bearing hole from the first air admission hole A of main axle unit cover 1, closed type two-direction thrust bearing module 2 entirety move backward, closed type two-direction thrust bearing module 2 is moved after being attached thereto by wherein endless belt is moving the thrusting plate 5 connecing, and thrusting plate 5 moves after driving post-tensioning cylinder body 6, thereby post-tensioning cylinder body 6 drives soft pawl to clamp workpiece, need to unclamp workpiece time, Compressed Gas enters in the seat of main shaft bearing hole from the second air admission hole B of main axle unit cover 1, then unclamps soft pawl by a series of parts. the two-way machine tool chief axis of built-in clamping device of said structure, is only suitable for the workpiece that processing dimension is less. because imperfection and the bearing roller of machining accuracy will produce under the objective circumstances of larger heat in the time rotating at a high speed, closed type two-direction thrust bearing module can not be made larger specification, because excessive workpiece certainly will cause the overall dimensions of lathe main axis device to strengthen, simultaneously, excessive workpiece needs larger clamping force, this need to process larger sized closed type two-direction thrust bearing module, the more axial forces of this module carrying simultaneously, to reach the clamping force of clamping work pieces, but the phenomenon that this structure causes heating to cause bearing to lose efficacy is in advance more serious, experimental data shows, the every increase by 1/3 of two-direction thrust bearing module specification, generate heat and be about original 1.8 times, bearing life is about original 1/2, simultaneously, due to the model of bearing, size has national standard, larger sized lathe main axis device, cause closed type two-direction thrust bearing module to become nonstandard product, processing cost increases.
