Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic drawings, which illustrate the basic structure of the present invention in a schematic manner, and thus show only the components related to the present invention.

A stator winding axial and radial synchronous clamping mechanism of a servo motor as shown in fig. 1 to 6, comprising: the collet 1 and the ram section 2 are positioned. The locating clip 1 is adapted to receive a core 3 therein. The press head 2 is adapted to clamp the core 3 axially and radially synchronously on the positioning collet 1. With respect to the above components, detailed description will be made below.

The positioning chuck 1 is cylindrical, the iron core 3 is also cylindrical, and the outer diameter of the iron core 3 corresponds to the inner diameter of the positioning chuck 1, so that the iron core 3 can be sleeved on the positioning chuck 1. After the iron core 3 is installed in the positioning chuck 1, when the iron core 3 is wound, the iron core 3 and the positioning chuck 1 are clamped in a radial direction and a circumferential direction, the positioning reliability is improved, and the rejection rate is reduced. In addition, a sliding groove 11 is formed in the end of the positioning chuck 1, and the sliding groove 11 is formed along the radial direction of the positioning chuck 1. The bottom of the sliding groove 11 is provided with a threaded hole 12.

The press head part 2 is arranged at the end of the positioning chuck 1 in a sliding manner, specifically, the width of the press head part 2 is matched with the width of the sliding groove 11, and the press head part 2 is arranged in the sliding groove 11 in a sliding manner. When 3 wire windings of iron core, press head portion 2 to follow sliding tray 11 radial slide to with 3 butts of iron core.

In order to achieve the above effect, the head pressing part 2 includes a slide block 21 and a pressing block 22. The extrusion block 22 is disposed on a side of the extrusion block 22 facing the iron core 3. The pressing block 22 is provided integrally with the slide block 21. With the above arrangement, when the slide block 21 slides in the slide groove 11, the pressing block 22 can be driven to slide to abut against the iron core 3.

When the pressing block 22 abuts the iron core 3, the iron core 3 is clamped. One side of the extrusion block 22 facing the iron core 3 is an arc surface 221, and the radian of the arc surface 221 is the same as that of the outer wall of the iron core 3. When the pressing block 22 abuts against the iron core 3, the iron core 3 is clamped by the arc surface 221.

In order to further limit the circumferential rotation of the iron core 3 when the extrusion block 22 clamps the iron core 3, a limit groove 31 is formed in the outer wall of the iron core 3 along the axial direction, and the limit groove 31 is arc-shaped. The arc surface 221 is provided with a limiting strip 222 along the length direction, and the limiting strip 222 corresponds to the limiting groove 31. After the limiting bar 222 is inserted into the limiting groove 31, the circumferential rotation of the iron core 3 is limited by the limiting bar 222. Through the arrangement, when the iron core 3 is positioned, the iron core 3 is driven to rotate until the limiting groove 31 corresponds to the limiting strip 222. The pressing block 22 slides along the sliding groove 11 until the limiting strip 222 is clamped into the limiting groove 31. To complete the clamping operation of the core 3.

In order to limit the pressing block 22 to the position abutting on the iron core 3 when the pressing block 22 abuts on the iron core 3, the press head part 2 further comprises a modified screw 23, and the modified screw 23 is arranged in the threaded hole 12. After the sliding block 21 is locked by the modified screw 23, the limit of the extrusion block 22 is realized.

In order to enable the sliding block 21 to slide along the sliding groove 11 before the sliding block 21 is locked by the modified screw 23, a waist-shaped groove 211 is formed in the sliding block 21, and the waist-shaped groove 211 is matched with the outer wall of the modified screw 23. Through the arrangement of the waist-shaped groove 211, when the sliding block 21 slides along the sliding groove 11, the modified screw 23 slides relative to the waist-shaped groove 211 to adjust the position of the sliding block 21. In addition, in order to enhance the positioning reliability of the modified screw 23 and the sliding block 21, an adjusting pad 25 is arranged between the end of the modified screw 23 and the sliding block 21. The adjusting pad 25 can fill up the gap between the end of the modified screw 23 and the sliding block 21, so that the effect of reinforcing the limit of the modified screw 23 and the sliding block 21 is achieved.

In order to further simplify the operation, a positioning pin 24 is provided at the end of the modified screw 23, and the positioning pin 24 is arranged perpendicular to the length direction of the modified screw 23. When the remanufacturing screw 23 rotates until the positioning pin 24 abuts against the extrusion block 22, the positioning pin 24 pushes the extrusion block 22 to slide towards the iron core 3. Through the arrangement, an operator only needs to screw down the modified screw 23, and the modified screw 23 can be driven to push the extrusion block 22 to clamp the iron core 3 through the positioning pin 24.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
