[0030] The flange plate 1012 is positioned in the recess groove at the bottom of the flange plate 1012, and after being matched with each other, the flange plate 1012 is installed on the machine tool spindle by the inner hexagonal screw. After being installed, the flange plate 1012 and the machine tool spindle are in the concentric state. The connecting head 103 is located inside the flange plate 1012, and is connected with the machine tool hydraulic rod through the thread at the bottom of the connecting head 103 (the hydraulic rod is located inside the machine tool spindle, and is concentric with the machine tool spindle). The slider 201 is slidably connected inside the mounting seat 101, and is connected with the front end of the connecting head 103 through the screw at the bottom of the slider 201. The slider 201 is connected with the bottom of the symmetrically distributed pressing plate 202 through the first pin 203 at both ends of the slider 201, and the second pin 204 passes through the mounting seat 101 and the waist round hole-shaped movable slot 2021 in the middle of the symmetrically distributed pressing plate 202.

The pressing plate 202 is connected with the mounting seat 101 by the second pin 204, so as to form a limiting structure. When the connecting head 103 is ejected outward, the pressing plate 202 is in the backward opening state under the simultaneous interaction of the profiling positioning connecting assembly 1 and the pull rod follow-up clamping assembly 2. The workpiece is placed in the middle position of the positioning block 102, so that the corresponding positions of the two are closely attached. Then the hydraulic switch is clicked, the connecting head 103 is retracted inward, and the pressing plate 202 is pressed firmly from the left and right sides of the workpiece, so as to complete the pressing of the workpiece. The hydraulic switch is clicked again, and the pressing plate 202 returns to the initial position, and the workpiece is taken out. Thus, one complete operation is ended.

[0032] It is worth noting that the whole device is controlled by the total control button, since the control button matches the commonly used device, which belongs to the existing mature technology, and the electrical connection relationship and specific circuit structure are not described here.

[0033] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
