[0021] Figure 1 The utility model is a three-dimensional diagram of the eccentric clamp for grinding the NC cutter seat. The eccentric clamp and the NC cutter seat 1 suitable for grinding the eccentric clamp for the NC cutter seat are shown in the figure.

[0022] like Figure 1-3 As shown, the rear end of the CNC cutting seat 1 is semi-cylindrical, and a groove 2 is provided on the surface. The CNC cutting seat grinding eccentric clamp includes: an eccentric clamp. The eccentric clamp is divided into an eccentric chuck 3 at the front end, an adapter 4 at the middle end, and a connecting piece 5 at the rear end. The adapter 4 and the connecting piece 5 of the eccentric clamp are both cylindrical. The lower end of the eccentric chuck 3 of the eccentric clamp is clamped in the groove 2 of the rear end of the CNC cutting seat 1. The eccentric chuck 3 of the eccentric clamp is eccentrically arranged so that the central axis of the front end of the CNC cutting seat 1 coincides with the central axis of the connecting piece 5 of the eccentric clamp.

[0023] The eccentric clamp 3 of the eccentric clamp is provided with a first screw hole, and the rear end of the CNC cutting seat 1 is provided with a second screw hole 6. The screw 7 penetrates the first screw hole and the second screw hole 6, and fixes the eccentric clamp 3 of the eccentric clamp and the rear end of the CNC cutting seat 1. In this embodiment, the first screw hole at the eccentric clamp 3 of the eccentric clamp and the second screw hole 6 at the rear end of the CNC cutting seat 1 are both provided with two, and the first screw hole and the second screw hole 6 are penetrated by two screws 7 respectively, and the eccentric clamp 3 of the eccentric clamp and the rear end of the CNC cutting seat 1 are fixed.

[0024] When in use, the groove 2 at the rear end of the CNC cutter seat 1 is clamped to the eccentric chuck 3 of the eccentric clamp, and two screws 7 are passed through the first screw hole and the second screw hole 6 to fix the eccentric chuck 3 of the eccentric clamp and the rear end of the CNC cutter seat 1. The connecting piece 5 of the eccentric clamp is connected to the external rotating component and driven to rotate, and the external grinding component processes the front end of the CNC cutter seat 1.

[0025] Furthermore, the diameter of the adapter 4 of the eccentric clamp is larger than the connecting piece 5 of the eccentric clamp, which provides the adapter 4 of the eccentric clamp with more position selection space, and the corresponding product name can be engraved on the surface of the adapter 4 facing the eccentric clamp 3 for easy identification.

[0026] Furthermore, a plurality of weight-removing holes 8 are provided on the outer wall of the adapter 4 of the eccentric clamp corresponding to the eccentric clamp head 3 of the eccentric clamp to achieve weight reduction and dynamic balance.

[0027] Furthermore, a cushion block 9 is provided on the front end face of the eccentric chuck 3 of the eccentric clamp, and the upper end face height of the cushion block 9 is lower than the height of the front end portion of the CNC cutting tool seat 1, so as to prevent external working equipment from accidentally touching the eccentric clamp and causing losses.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
