Description

Technical Field

[0001] This utility model relates to the field of machinery, and more particularly to tooling fixtures, especially a tooling fixture for manually inserting pins into the three-phase six-slot stator of a small fan. Background Technology

[0002] Traditional small wind turbines use a single-phase four-slot stator structure. The stator manufacturing process requires inserting two copper-tin-plated steel pins into the coil support. These pins act as a conductive medium, guiding current from the external power supply into the stator winding coils. The assembly of these pins is completed using semi-automatic equipment. With technological advancements, more and more small wind turbines are adopting three-phase six-slot stators. Existing customized equipment is only suitable for single-phase four-slot stators and not for three-phase six-slot stators, thus failing to meet the production requirements of three-phase six-slot stators. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling fixture for manual insertion of stator pins in a three-phase six-slot stator of a small wind turbine, in order to solve the technical problem that the customized equipment in the prior art is not suitable for the stator pin insertion requirements of a three-phase six-slot stator.

[0004] This utility model provides a tooling fixture for manual pin insertion of a three-phase six-slot stator in a small fan, including a cylindrical base with a limit post at the center of the upper side of the base. The limit post is cylindrical, and an upper cover plate is provided above the base. A central hole is provided through the center of the upper cover plate, which is fitted onto the limit post through the central hole. Four guide holes are provided at intervals around the outer periphery of the central hole in the upper cover plate. A limit ring is coaxially provided on the lower surface of the upper cover plate around the central hole. Four positioning structures are provided at intervals along the circumferential direction on the lower surface of the upper cover plate around the limit ring. Each positioning structure includes two positioning blocks spaced at intervals along the circumferential direction. The gap between the two positioning blocks forms a positioning groove. The four positioning grooves are correspondingly provided below the four guide holes. At least two limit blocks are provided at intervals along the circumferential direction on the outer edge of the lower surface of the upper cover plate.

[0005] Furthermore, the number of the limiting blocks is three.

[0006] Compared with the prior art, the advantages of this utility model are positive and obvious. This utility model provides a tooling fixture for manual pin insertion of three-phase six-slot stators for small wind turbines. It is suitable for the manual pin insertion process of small wind turbine stators, meeting the installation and positioning requirements of three-phase six-slot stators during pin insertion. It has a simple structure, low cost, convenient operation, and accurate positioning, enabling rapid and efficient assembly of three-phase six-slot stators and improving the production efficiency of three-phase six-slot stators.

[0013] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included within the protection scope of the present invention. The use of directions such as up, down, front, back, left, right, center, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0014] like Figures 1-6 As shown, this utility model provides a tooling fixture for manual pin insertion of a three-phase six-slot stator in a small fan, including a cylindrical base 1, a limiting post 2 set at the center of the upper side of the base 1, the limiting post 2 being cylindrical, an upper cover plate 3 set above the base 1, a central hole 4 penetrating through the center of the upper cover plate 3, the upper cover plate 3 being sleeved on the limiting post 2 through the central hole 4, four guide holes 5 spaced apart on the outer periphery of the central hole 4 in the upper cover plate 3, a limiting ring 6 coaxially set on the lower surface of the upper cover plate 3 on the outer periphery of the central hole 4, four positioning structures spaced apart on the lower surface of the upper cover plate 3 on the outer periphery of the limiting ring 6 in the circumferential direction, each positioning structure including two positioning blocks 7 spaced apart in the circumferential direction, the gap between the two positioning blocks 7 forming a positioning groove 8, the four positioning grooves 8 being correspondingly set below the four guide holes 5, and at least two limiting blocks 9 spaced apart in the circumferential direction on the outer edge of the lower surface of the upper cover plate 3.

[0015] Furthermore, the number of limiting blocks 9 is three.

[0016] The working principle of this utility model:

[0017] The three-phase six-slot stator 10 is placed on the outer periphery of the limiting post 2 on the base 1. The upper cover plate 3 is installed above the three-phase six-slot stator 10. The four positioning structures cooperate with the four pin holes. The positioning blocks 7 are located on both sides of the pin holes, so that the four positioning grooves 8 are aligned with the four pin holes of the three-phase six-slot stator 10 respectively. The limiting ring 6 is located on the end face between the inner and outer rings of the three-phase six-slot stator 10. The limiting block 9 is located on the outer side of the outer ring of the three-phase six-slot stator. The four pins are respectively placed into the four guide holes 5 of the upper cover plate 3. The pins are pressed from top to bottom by a manual press. The manual press stops after contacting the limiting post 2, so that the four pins are pressed into the pin holes of the three-phase six-slot stator 10. The pin height is guaranteed by the limiting post 2, and the pin assembly of the three-phase six-slot stator is completed.

[0018] This utility model discloses a tooling for manual stator pin insertion, which is suitable for the manual pin insertion process of small fan stators. It meets the installation and positioning requirements of three-phase six-slot stators during pin insertion. It has a simple structure, low cost, convenient operation, and accurate positioning, and can quickly and effectively assemble three-phase six-slot stators, thereby improving the production efficiency of three-phase six-slot stators 10.
