Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 and 2, the embodiment of the utility model provides an automatic anchor clamps are used in connector processing, including 3R anchor clamps 1 and dovetail anchor clamps 2, 3R anchor clamps 1 fixed connection is on the workstation of digit control machine tool 3, dovetail anchor clamps 2 fixed connection is on 3R anchor clamps 1, the upper end of dovetail anchor clamps 2 is equipped with dovetail centre gripping groove 21.

In this embodiment, digit control machine tool 3 is five-axis digit control machine tool (five-axis digit control machine tool in the drawing is the schematic diagram only, does not represent five-axis digit control machine tool's concrete structure, the utility model is suitable for an any one section five-axis digit control machine tool), 3R anchor clamps 1 fixed connection is on five-axis digit control machine tool 3's swivel work head. The 3R clamp is preferably a JS-6035-CNC CNC pneumatic quick reference chuck (shown in FIG. 3).

The dovetail-shaped clamping groove 21 is adjustable in groove width.

As shown in fig. 4 and 5, in the present embodiment, the slot width of the dovetail-shaped holding slot is adjustable by the following structure: a notch 211 is arranged at one side of the dovetail-shaped clamping groove 21, a sliding clamping block 22 capable of moving along the notch 211 in the groove width direction is embedded in the notch 211, the inner side face of the sliding clamping block 22 is a dovetail face, and the dovetail-shaped clamping groove 21 can be adjusted in groove width through the movement of the sliding clamping block 22.

The sliding clamping block 22 is moved along the indentation 211 by the driving action of the driving means.
