DETAILED DESCRIPTION
[0023] The motor stator core angular positioning clamping device comprises a positioning ring plate 1 and an internal tensioner 2 (see the appendix of the manual). Figure 2 and 3 ).
[0024] The interior of the positioning ring plate 1 is equipped with an internal tensioner 2 (see the appendix of the manual) through the lifting plate 3. Figure 2 and 3 ).
[0025] The internal tensioner 2 includes a guide cylinder 10, a core shaft 11, a push cylinder 13, a pressing sleeve 14 and a support plate 12 (see the appendix of the specification). Fig. 9 ).
[0026] A guide cylinder 10 is fixedly mounted on the lifting plate 3; a core shaft 11 is slidably mounted in the guide cylinder 10; a push cylinder 13 is fixedly mounted at the lower end of the guide cylinder 10; the push cylinder 13 is connected to the core shaft 11. The push cylinder 13 can drive the core shaft 11 to move up and down inside the guide cylinder 10.
[0027] The upper end of the guide cylinder 10 is fixed with a support plate 12; the support plate 12 is surrounded by an arc-shaped guard plate 18 (see the attached manual). Figure 8 ).
[0028] The upper end of the mandrel 11 is fixed with an extrusion sleeve 14 (see the attached manual Figure 8 , 9 and 10). When the core shaft 11 moves, it can drive the extrusion sleeve 14 to move up and down. The cross section of the extrusion sleeve 14 is a trapezoidal structure (see the attached Fig.10 ).
[0029] A guide ring 15 is fixedly mounted on the support plate 12 outside the extrusion sleeve 14; and extrusion balls 17 are mounted on the guide ring 15 through a plurality of uniformly arranged guide holes 16. The guide holes 16 are trumpet-shaped. The purpose of setting the guide holes 16 in a trumpet-shaped structure is to confine the extrusion balls 17 inside the guide holes 16 to avoid the problem of the extrusion balls 17 being separated from the guide holes 16.
[0030] A plurality of positioning components 4 are evenly mounted on the positioning ring plate 1 around the inner tensioner 2; the positioning component 4 includes a sliding seat 5, a limit block 8 and a positioning card plate 6 (see the attached manual Figure 5 and 6 ).
[0031] A sliding seat 5 is mounted on the positioning ring plate 1 through a guide rail; a positioning clamping plate 6 is mounted on the sliding seat 5; a positioning cylinder 7 is mounted on the positioning ring plate 1 on one side of the sliding seat 5; one end of the positioning cylinder 7 is connected to the sliding seat 5. When the positioning cylinder 7 is working, it can drive the positioning clamping plate 6 to move back and forth through the sliding seat 5.
[0032] A limit block 8 is installed on the positioning ring plate 1 at one end of the positioning cylinder 7. The purpose of setting the limit block 8 is that when the positioning cylinder 7 drives the sliding seat 5 to move back and forth, when the sliding seat 5 conflicts with the limit block 8, the limit block 8 will hinder the movement of the sliding seat 5, so that the purpose of limiting the moving position of the sliding seat 5 and the positioning clamping plate 6 by the limit block 8 can be achieved.
[0033] The end of the positioning card plate 6 is an arc-shaped structure; the end of the positioning card plate 6 is provided with a clamping protrusion 9 (see the attached manual Figure 6 ). The arc surface of the end of the positioning clamp 6 is consistent with the curvature of the surface of the workpiece (motor stator core), so that when working, the positioning clamp 6 can be pressed tightly against the arc surface of the workpiece through the arc surface of its end.
[0034] The clamping protrusion 9 at the end of the positioning clamping plate 6 corresponds to the slot on the surface of the workpiece (motor stator core), so that during operation, the clamping protrusion 9 at the end of the positioning clamping plate 6 can be inserted into the slot on the surface of the workpiece, thereby achieving the purpose of positioning.
[0035] When the motor stator core angular positioning clamping device is working, the workpiece is first placed on the support plate 12 through external equipment, and the guide ring 15 is located inside the workpiece; then the push cylinder 13 drives the core shaft 11 to move upward, so that the extrusion sleeve 14 presses the extrusion ball 17 through the conical surface on its surface, so that it moves outward along the guide hole 16, and finally expands the workpiece from the inside.
[0036] After the internal tensioner 2 tensions the workpiece, the lifting plate 3 drives the workpiece to move down to correspond to the positioning assembly 4 through the internal tensioner 2. Then the positioning cylinder 7 of the positioning assembly 4 drives the positioning clamping plate 6 to move toward the workpiece through the sliding seat 5, and finally presses the workpiece into position from the outside.
[0037] After that, the workpiece can be assembled; after the workpiece is assembled, the inner expander 2 and the positioning assembly 4 release the workpiece, and the positioning clamping device can enter the next working cycle.
[0038] The motor stator core angular positioning clamping device has a compact structure and ingenious design. It can clamp and position the workpiece from both the inside and the outside, thereby solving the problem of easy damage to the workpiece in the existing motor stator core clamping method. The device is particularly suitable for the needs of angular positioning and clamping of the motor stator core.
