Description
Technical field
The present invention relates to a kind of clamp system.
Background technology
Motor is electrical equipment conventional in daily life, and motor has stators and rotators to form, and there is coil in its rotor Shangrao, will be fixed in the winding process of rotor to rotor, and fixed rotor just needs to use clamp system.Existing clamp system is generally that support arranges chuck overcoat by bearing, in chuck overcoat, collet is set, collet stretches thus the workpiece clamping or unclamp clamped by collet in chuck overcoat, collet is connected with driving mechanism such as cylinder etc. by pull bar, pull bar is pulling in collet, axial active force can be produced to bearing, easily destroy bearing, reduce the service life of bearing.
Summary of the invention
The object of this invention is to provide a kind of clamp system, solve the technological deficiency of prior art middle (center) bearing axially loaded, improve the service life of bearing, thus improve the service life of whole clamp system.
For solving the problem, the technical solution used in the present invention is:
A kind of clamp system, comprises
Main shaft frame;
Be arranged on the clutch shaft bearing seat of main shaft frame one end;
The chuck overcoat be arranged in clutch shaft bearing seat is rotated by two bearings, between the inner ring of two bearings, spacer is set, chuck overcoat has the central through hole running through two ends along axis, in central through hole, collet is set, on collet, radial direction has the first through hole, horn-like little in the large rear end, front end of matching with collet in one end of central through hole, bearing sliding bush has groove, and chuck overcoat is fixed with the first spring base away from one end of collet;
Pull bar, one end of pull bar to be stretched in chuck overcoat and is threaded with collet, the other end of pull bar is rotated by bearing and is arranged on the second bearing block, pull bar and bearing inner race matched in clearance, second bearing block is arranged on the other end of main shaft frame, one end near the second bearing block on pull bar arranges the second spring base, and the second spring base is between the first spring base and the second bearing block, and pull bar has second through hole corresponding with the first through hole with one end radial direction that collet connects;
Compress Spring, Compress Spring is enclosed within pull bar, and Compress Spring is between the first spring base and the second spring base;
Square key, square key to arrange in spacer and runs through groove, the first through hole and the second through hole;
Fork, the top being arranged on main shaft frame is rotated at the top of fork by bearing pin, the middle part of fork contacts with the second spring base and pushing drawing rod in axial direction moves back and forth;
Be arranged on the cylinder of main shaft frame bottom, the piston of cylinder can promote fork rotate around bearing pin with fork lower contacts.
The present invention arranges the first spring base and the second spring base, cylinder piston extends, promote fork to rotate around bearing pin, fork promotes the second spring base makes Compress Spring be in compressive state, Compress Spring promotes the first spring base, because the first spring base and chuck overcoat fix, so, the left thrust of clutch shaft bearing seat is applied on the clutch shaft bearing on the left side by spacer, and clutch shaft bearing is subject to active force left.Because the second spring base is arranged on pull bar, so pull bar moves together with the second spring base, promote the collet be connected with pull bar, thus unclamp the workpiece etc. clamped by chuck.Cylinder piston shrinks, Compress Spring extends and resets, promote the second spring base to move to the direction away from collet together with pull bar, pull bar pulls collet to shrink in chuck overcoat, thus clamping work pieces, in the process, 1. pull bar receives Compress Spring thrust to the right, and pull collet to shrink as in chuck overcoat, collet shrinks and applies towards the active force in the second bearing block direction to chuck overcoat in chuck overcoat, inner ring due to clutch shaft bearing and the second bearing is fixed on outside chuck and puts, so clutch shaft bearing and the second bearing are subject to towards the active force in the second bearing block direction, 2. when Compress Spring extends and resets, first spring base is compressed the active force of spring, the direction of power is towards the direction away from the second bearing block, because the second spring base is fixed on outside chuck and puts, so chuck overcoat is subject to the active force away from the second bearing block direction, clutch shaft bearing and the second bearing are subject to chuck overcoat to both towards the active force away from the second bearing holder (housing, cover), because the amount of force of Compress Spring to the first spring base and the second spring base is equal, direction is contrary, so active force 1. with 2. in amount of force equal, direction is contrary, clutch shaft bearing and the second shaft strength balance, cancel out each other, be equivalent to clutch shaft bearing and the second bearing does not bear axial force.In the process of above-mentioned collet axially-movable, the reciprocating ultimate range of collet is exactly the length of groove, and the matched in clearance of pull bar and bearing inner race, makes pull bar to move in the axial direction and to keep position of bearings motionless.Bearing by axial power, can not make significantly extend the service life of bearing, thus the service life of whole clamp system is extended.
As a further improvement on the present invention, fork comprises two poles on top and the push rod of bottom, and the top of main shaft frame arranges bearing, and the top of two poles is rotated by bearing pin and is arranged on bearing, pull bar passes in the middle of two poles, and the second spring base is moved back and forth by pole promotion.
The top of push rod is two poles, is namely convenient to pull bar through push rod, again because the both sides of the second spring base are all stressed, so fork in rotation the second spring base stressed evenly.
As a further improvement on the present invention, two poles are provided with towards the projection of the second spring base, the second spring base and projection contacts.
Arrange projection, make the second spring base stressed more reasonable, if this fork is flat, then the lower edge that can only be the second bearing block at the end face of impeller-hub bearing contacts with this bar, and the second spring base is stressed unreasonable.
As a further improvement on the present invention, push rod is in the arc towards collet curving, and the bottom of main shaft frame arranges two optical axises, and optical axis is arranged the slide block that can slide on optical axis, the piston rod connection sliding block of cylinder, push rod is by slipper push.
Push rod is curved, can be slide block and reserves enough spaces.
As a further improvement on the present invention, the one end away from cylinder on main shaft frame arranges limited post, and limited post is between two optical axises.
Arrange limited post, make restriction to the rotation amplitude of fork, namely make restriction to the suppressed range of spring and the motion amplitude of pull bar, the scope preventing collet flexible in chuck overcoat is excessive.
As a further improvement on the present invention, clamp system also comprises motor, and motor and cylinder are positioned at the same side of main shaft frame, and the output shaft of motor is connected with pull bar.
Motor can drive pull bar, chuck overcoat, collet, the first spring base, the second spring base etc. to rotate together, and facilitating follow-up is such as the work of electric machine winding etc.
As a further improvement on the present invention, in collet, locating dowel is set.
Locating dowel is set in collet, the length that the workpiece that clamp extend in collet is limited.
In sum, the invention has the beneficial effects as follows: solve collet in flexible process, the technological deficiency of bearing axially loaded, and structure of the present invention is simple, easy to use.
