A motor stator winding shaping device

Abstract

This utility model belongs to the field of hand tools and relates to a motor stator winding shaping device. It mainly consists of two parts: two positioning slots and two bearing washers. The two positioning slots are respectively installed on both sides of the stator, and bearing washers are installed on the positioning slots on both sides. Small shafts on both sides of the stator pass through the central mounting holes of the positioning slots and the bearing washers in sequence and are secured with lock nuts. This utility model solves the problem in the current production and assembly process where the height of the coil after forming does not meet the assembly requirements due to factors such as complex structure, high slot fill factor, and thin wire diameter.

Description

Technical Field

[0001] This utility model belongs to the field of hand tools and relates to a motor stator winding shaping device. Background Technology

[0002] The motor stator is an important component of a sensor motor, primarily functioning within the motor. It rotates using the electromagnetic force acting on the stator coils, and its structure is as follows: Figure 1 As shown. However, in the current production and assembly process, due to its complex structure, high slot fill factor, and thin wire diameter, the height of the coil after forming does not meet the assembly requirements, making it very difficult to adjust its shape. Therefore, a tool is needed to meet the usage requirements. Summary of the Invention

[0003] The purpose of this utility model is to fix the tooling after the stator winding is completed and to adjust the shape of the stator coil.

[0004] The technical solution of this utility model is: a motor stator winding shaping device, which mainly consists of two parts: two positioning grooves and two bearing washers; the two positioning grooves are respectively installed on both sides of the stator, and bearing washers are respectively installed on the positioning grooves on both sides. The small shafts on both sides of the stator pass through the central mounting holes of the positioning grooves and the bearing washers in sequence and are fastened by locking nuts.

[0005] One end of the positioning groove is adapted to the contact surface of the stator winding after winding, and the other end has a groove on its end face, which is adapted to the bearing gasket.

[0006] The central mounting hole of the positioning groove is adapted to the stator shaft.

[0007] The positioning groove is made of polytetrafluoroethylene.

[0008] The bearing gasket is a ball bearing D90013×M36.

[0009] The stator has threaded locking nuts at both ends of the small shafts on both sides.

[0010] The technical effect of this utility model is that it solves the problem that the height of the coil after forming does not meet the assembly requirements due to the complex structure, high slot fill factor, and thin wire diameter of the current production and assembly process by using a motor stator winding shaping device.

[0016] The present invention will be further described below with reference to the accompanying drawings:

[0017] like Figure 2 As shown in Figure 5, a motor stator winding shaping device mainly consists of two parts: two positioning slots and two bearing washers. The two positioning slots are respectively installed on both sides of the stator, and bearing washers are installed on the positioning slots on both sides. The small shafts on both sides of the stator pass through the central mounting holes of the positioning slots and the bearing washers in sequence and are fastened by locking nuts.

[0018] One end of the positioning groove is adapted to the contact surface of the stator winding after winding, and the other end has a groove on its end face to adapt to the bearing gasket. The position is adjusted by using the threaded locking nuts at both ends of the stator shaft.

[0019] The central mounting hole of the positioning groove is adapted to the stator shaft.

[0020] The positioning groove is made of polytetrafluoroethylene (PTFE). It is compatible with the parts and is characterized by low hardness and inert chemical properties, so it will not stick to the molding adhesive.

[0021] The stator has threaded locking nuts at both ends of the small shafts on both sides.

[0022] Using the ball bearing (D90013×M36) of the shelf product as a positioning groove bearing gasket ensures that the rotation of the nut during product assembly will not cause the tooling to rotate. It only transmits pressure, not torque, and will not drive the tooling to rotate, thus avoiding wear on the wound product.

[0023] How to use:

[0024] 1) After the stator winding is completed, the operator applies a layer of X98-11 adhesive to the motor stator assembly that needs to be shaped, allowing the adhesive to penetrate into the winding.

[0025] 2) Install the positioning slots of the shaping tooling on both sides of the stator to fix the winding on the working surface. Install bearing washers on both sides, and then tighten the product lock nuts.

[0026] 3) Place the stator of the installation fixture into a 90℃ oven and dry it for 2 hours.

[0027] 4) Once the stator has returned to room temperature, remove the fixture.

[0028] 5) Check the stator performance test items.
