Detailed Description

Example 1

The present invention will be further described with reference to the accompanying drawings and embodiments, but the present invention is not limited to this embodiment, and the protection scope of the present invention should be included in all similar structures and similar variations thereof.

As shown in fig. 1-7, the utility model discloses a motor stator anchor clamps for dripping lacquer technology, including three-jaw chuck, three-jaw chuck includes drive arrangement (not shown in the figure) and three outer clamping jaw 1, drive arrangement passes through drive mechanism (not shown in the figure) and three outer clamping jaw 1's trailing end connection, three outer clamping jaw 1 is along circumferencial direction evenly distributed, three outer clamping jaw 1's head end all is connected with a connecting block 3 through locating pin 2 separately, three connecting block 3 all is connected with a fixture block 4 separately, three fixture block 4 all can be dismantled with connecting block 3 separately and be connected, all be provided with a draw-in groove 11 on three fixture block 4 separately, three draw-in groove 11 all faces three-jaw chuck's axle center separately.

Further, the outer clamping jaw 1 comprises a first clamping arm 12, a second clamping arm 6, a third clamping arm 9 and a fourth clamping arm 10 respectively, the second clamping arm 6 is vertically connected to the tail end of the first clamping arm 12 and the head end of the third clamping arm 9, the fourth clamping arm 10 is vertically connected to the tail end of the third clamping arm 9, and the arrangement direction of the head end and the tail end of the first clamping arm 12 and the arrangement direction of the head end and the tail end of the third clamping arm 9 are consistent with the arrangement direction of the head end and the tail end of the outer clamping jaw 1.

Furthermore, a triangular rib 7 is arranged between the second clamping arm 6 and the third clamping arm 9.

Furthermore, the cross section of one of the slots 11 is trapezoidal, and the cross sections of the other two slots 11 are arc-shaped.

Specifically, the three-jaw chuck, the driving device, and the like in the present embodiment all adopt the known solutions in the prior art, which are known to those skilled in the art and will not be described herein again.

The working principle of the embodiment is as follows:

1. the utility model discloses with the change of internal stay formula for outer clamp mode, put into motor stator 5 along three-jaw chuck opening part, the outer clamping jaw 1 of drive drives presss from both sides tight motor stator 5 inwards, and motor stator 5's installation piece card is in trapezoidal draw-in groove 11, and motor stator 5's outer periphery and arc draw-in groove 11 are laminated completely, prevent that outer clamping jaw 1 from colliding with, the impression etc. to motor stator 5 surface production.

2. The length of the fixture block 4 is set to be the thickness of the corresponding motor stator core, the position of the motor stator 5 relative to the clamping jaws can be quickly positioned, the feeding can be completed only by aligning the outer diameter of the motor stator 5 with the three outer clamping jaws 1, and the feeding step is simplified.
