FIG. 1 is a schematic view of the structure of the main shaft and tool shank dismounting device of the numerical control milling machine of the present invention;

fig. 2 is the utility model discloses well numerically controlled fraise machine main shaft handle of a knife dismounting device's plan view.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples.

Example 1

A numerical control milling machine spindle tool shank dismounting device is shown in figures 1-2 and comprises a support ring 100, a lifting table 101, a pin bolt 102, a clamping jaw 103, a coupler 104, a direct current motor 105 and a base 106, wherein the support ring 100 is fixed on the base 106, the direct current motor 105 is connected with the pin bolt 102 through the coupler 104, one end, far away from the coupler 104, of the pin bolt 102 is connected with the lifting table 101, and the clamping jaw 103 is fixed on the lifting table 101.

The base 106 is provided with four screw holes, and the support ring 100 is fixed on the base 106 by bolts matching with the screw holes.

The pin bolt 102 is connected with the center of the lifting platform 101 in a threaded manner.

The clamping jaws 103 are welded and fixed on two sides of the upper end face of the lifting platform 101.

The dc motor 105 is capable of forward and reverse rotation.

The support ring 100, the lifting platform 101, the pin bolt 102, the clamping jaw 103, the coupler 104 and the direct current motor 105 are standard components.

The working principle is as follows: firstly, a jaw 103 is clamped in a groove of a tool shank of a numerical control milling machine and used for stroke positioning of a main shaft of the numerical control milling machine, a direct current motor 105 is connected with a pin bolt 102 by a coupler 104, the direct current motor 105 is electrified and driven, the pin bolt 102 is driven to rotate by the coupler 104, the pin bolt 102 is in threaded connection with a lifting platform 101, the lifting platform 101 moves downwards due to rotation of the pin bolt 102, the torsional force of the motor is larger than the force of the tool shank clamped on the main shaft of the machine tool, the purpose of dismounting the tool shank is finally achieved, the lifting platform 101 is moved up and down through positive and negative rotation of the direct current motor 105, and the rotation motion is.

Specifically, when a tool shank of the numerically controlled milling machine is clamped on a machine tool spindle, a machined workpiece is taken off at first, the machine tool spindle is lowered to a proper position, then a clamping jaw 103 of a dismounting tool is used for clamping a groove of the tool shank of the numerically controlled milling machine, at the moment, a spindle Z shaft of the machine tool moves up and down for fine adjustment until a lifting platform 101 is debugged to the middle part of a support ring 100, the proper position of the tool shank of the numerically controlled milling machine can be dismounted, after the preparation work is completed, a direct current motor 105 is started, the lifting platform 101 starts to descend through a coupler 104 and a pin bolt 102, the tool shank of the numerically controlled milling machine is separated from the machine tool spindle by using the torsional force of the direct current motor 105, and.

While the preferred embodiments of the present invention have been described, additional variations and modifications in those embodiments may occur to those skilled in the art once they learn of the basic inventive concepts. It is therefore intended that the appended claims be interpreted as including the preferred embodiment and all such alterations and modifications as fall within the scope of the invention.

It will be apparent to those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims and their equivalents, the present invention is also intended to include such modifications and variations.
