Abstract

The utility model provides a new forms of energy motor shaft peripheral milling quick clamping frock, the hole that is equipped with the equipartition on the anchor clamps body, the front portion in hole is divided into the blind hole, the rear portion is divided into the screw hole, circle is crossed mutually in blind hole and the anchor clamps body, install the ball in the blind hole, make the ball be located the blind hole and circle is crossed mutually with the anchor clamps body, the pressure spring is pressed on the ball to be connected through jackscrew and the specific screw hole of anchor clamps, the anchor clamps body external pressure presses the encapsulation cover, the two interference fit, the encapsulation cover passes through threaded connection with the drive. The clamping device has the advantages that the clamping time of each workpiece is shortened to 1s, the operation is simple, the clamping is reliable, the defects of clamping damage and the like cannot be left on the surface of the workpiece, and the production efficiency and the product quality are greatly improved.

Description

Rapid clamping tool for cylindrical grinding of new energy motor shaft

Technical Field

The utility model relates to a quick clamping frock of new forms of energy motor shaft peripheral milling.

Background

When carrying out the excircle grinding at present, new forms of energy motor shaft often adopts the heart to press from both sides and carry out the centre gripping to the work piece, then installs and carry out the grinding at the excircle bed, when using the heart to press from both sides the centre gripping, uses the hexagon socket head cap jackscrew to press from both sides tightly, and this kind of mode not only presss from both sides easily and hinders the work piece, and the centre gripping is also not firm, and clamping inefficiency moreover, complex operation.

Disclosure of Invention

An object of the utility model is to solve the above-mentioned current problem that exists, provide an efficient, easy operation, reduce the quick clamping frock of new forms of energy motor shaft excircle mill that presss from both sides the injury.

The utility model discloses a realize through following technical scheme: the hole that is equipped with the equipartition on the anchor clamps body, the front portion in hole is divided into the blind hole, and the rear portion is divided into the screw hole, and the blind hole is crossed mutually with anchor clamps internal circle, installs the ball in the blind hole, makes the ball be located the blind hole and presss from both sides internal circle department of crossing mutually, and the pressure spring is pressed on the ball to be connected with the specific screw hole of anchor clamps through the jackscrew, the anchor clamps external pressure encapsulation cover, the two interference fit, the encapsulation cover passes through threaded connection with the drive swing arm.

The utility model has the advantages of, when using original clamping method, every work piece clamping time is about 5s, and complex operation moreover often appears pressing from both sides and hinders and cause the product to scrap in workpiece surface, and used the utility model discloses behind the quick clamping frock of cylindrical grinding, every work piece clamping time shortens to 1s, easy operation moreover, and the clamping is reliable, can not leave the defect such as pressing from both sides and hinder on workpiece surface simultaneously, provides production efficiency and product quality greatly.

FIG. 3 is a sectional view of the clamp body of the present invention

FIG. 4 is a left side view of FIG. 3

Fig. 5 is a front view of the package cover of the present invention.

Detailed Description

The following detailed description is made with reference to the accompanying drawings: as shown in the figure, uniformly distributed holes are formed in the clamp body 1, the front portion of each hole is a blind hole 1-2, the rear portion of each hole is a threaded hole 1-1, the blind holes 1-2 penetrate through the inner circle of the clamp body 1, balls 2 are mounted in the blind holes 1-2, the balls 2 are located at the positions, where the blind holes 1-2 penetrate through the inner circle of the clamp body 1, the balls 2 are pressed on the balls 2 and are connected with the threaded holes 1-1 of the clamp body 1 through jackscrews 4, a packaging sleeve 5 is pressed outside the clamp body 1 and is in interference fit with the clamp body, the packaging sleeve is in threaded connection with the driving swing arm, and a workpiece 7 is inserted into the inner hole of the.

During the use, work piece 7 unidirectional rotation inserts anchor clamps body 1 hole, simultaneously with ball 2 contact, and ball 2 atress extrusion spring 3 takes place the displacement simultaneously, and work piece 7 can insert, and drive swing arm 6 and grinding machine head frame driving lever vertical contact form the cross. When the grinding machine is started, the driving rod of the grinding machine head frame rotates to drive the driving swing arm 6 at the crossed position to rotate, the clamp body 1 starts to rotate along with the driving rod, the ball 2 is self-locked in one direction at the moment, meanwhile, the ball 2 clamps the workpiece 7, and the workpiece 7 rotates along with the driving rod.

Claims

1. The utility model provides a new forms of energy motor shaft peripheral milling quick clamping frock, its characterized in that, the hole that is equipped with the equipartition on the anchor clamps body, the front portion in hole is divided into the blind hole, the rear portion is divided into the screw hole, the blind hole passes through mutually with the anchor clamps body interior circle, install the ball in the blind hole, make the ball be located the blind hole and the anchor clamps body interior circle department of passing through mutually, the pressure spring is pressed on the ball to be connected through jackscrew and the specific screw hole of anchor clamps, the anchor clamps body external pressure dress encapsulation cover, the two interference fit, the encapsulation cover passes through threaded connection.
