Moreover, the workpiece positioning groove is a V-shaped groove.
And the front end of the lower part of the positioning insertion plate is made into an inclined surface.
And the left end and the right end of the pressing plate are both installed on the left side and the right side of the upper surface of the base through jackscrews.
And the lower bottom surface of the base at the side edge of the through hole is made into an inclined surface.
The invention has the advantages and positive effects that:
1. the equipment comprises a circular chuck, a base, a positioning column, an upper cover plate, a positioning insertion plate and a pressing plate, wherein a workpiece is placed in a workpiece positioning groove of the base, and is positioned and locked by the positioning column, the positioning insertion plate and the pressing plate. The positioning locking mode is simple, convenient and easy to master, and provides convenience for the operation of workers, so that the time for disassembling and assembling workpieces can be reduced, and the working efficiency can be improved.
2. The circular chuck of this equipment is installed on four-axis machining center, uses four-axis machining center can once only accomplish the processing in two holes of work piece to can play good guarantee effect to product processingquality, consequently can reduce the rejection rate, save manufacturing cost for the enterprise.
3. The front end (the end contacted with the workpiece) of the lower part of the positioning inserting plate of the equipment is made into an inclined surface, so that the insertion and positioning of the workpiece can be facilitated.
4. The equipment makes the bottom surface of the base at the side edge of the through hole into an inclined plane so as to meet the requirement of the stroke of the drill bit.
5. The clamping device is a clamping device which is arranged on a four-axis machining center and used, has reasonable structure, convenient use, strong practicability and low manufacturing cost, is specially used for a tool clamp used on the four-axis machining center, can complete the machining of two procedures by clamping once, and can improve the machining precision, accelerate the production speed, improve the product percent of pass and reduce the production cost of enterprises after being used.

Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings; it should be noted that the present embodiment is illustrative, not restrictive, and the scope of the invention should not be limited thereby.
The utility model provides an install dress card equipment that uses on four-axis machining center, includes circular chuck 2, base 5, reference column 9, upper cover plate 3, location picture peg 6 and clamp plate 4, makes a plurality of mounting holes 1 along the circumferencial direction equipartition on the circular chuck, and circular chuck is connected with four-axis machining center through this mounting hole.
The front surface of the circular chuck is coaxially provided with a base, a workpiece positioning groove 8 is coaxially manufactured in the base, and the workpiece positioning groove is a V-shaped groove. The axis of the circular chuck is coaxially provided with a positioning column in a penetrating way, and the front end of the positioning column is positioned in the workpiece positioning groove of the base. An upper cover plate is arranged on the front surface of the rear part of the base, a vertical positioning insertion plate is arranged between the upper cover plate and the front surface of the base, the lower bottom surface of the positioning insertion plate is positioned in a workpiece positioning groove, and the front end (the end contacted with a workpiece) of the lower part of the positioning insertion plate is made into an inclined surface.
