Description

Technical Field

[0001] The utility model belongs to the technical field of stator core processing, in particular to a stator core coating processing die. Background Art

[0002] After the stator core is formed, apply thermal grease on the heat dissipation surface of the stator core, install a thin copper sheet, and finally assemble it with the motor housing. A mold is required to assist in coating the stator core.

[0003] The existing stator core coating processing mold is fixed in size and has no adjustment function. When stator cores of different sizes need to be used, different molds need to be replaced, which not only increases the cost of using the mold, but also requires staff to spend a lot of time when replacing it. At the same time, it is inconvenient to operate and reduce production efficiency. Therefore, we proposed a stator core coating processing mold. Utility Model Content

[0004] The purpose of the utility model is to provide a stator core coating processing mold, which can clamp and fix stator cores of different sizes by setting an adjustment component, thereby eliminating the need to replace the mold, reducing the labor of the staff, and reducing the cost of using the mold. It solves the problem that when stator cores of different sizes need to be used, different molds need to be replaced, which not only increases the cost of using the mold, but also requires the staff to spend a lot of time when replacing them.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a stator core coating processing mold, including a mold, a stator core is arranged on the top of the mold, an adjustment component is arranged at the center of the top of the mold, the adjustment component includes a column, a plurality of clamps are arranged on the outside of the column, the plurality of clamps are arranged in a circular array with the column as the center, the parts contained in the plurality of clamps are the same, and by setting the adjustment component, stator cores of different sizes can be clamped and fixed, so there is no need to replace the mold, reducing the labor of the staff and reducing the cost of using the mold.

[0007] Furthermore, a trapezoidal block is fixedly connected to one side of the splint close to the column, a cavity is opened inside the column, a plurality of limit grooves are opened on the inner wall of the cavity, and the limit grooves are arranged in a circular array with the column as the center, a push block is arranged inside the cavity, the bottom of the column is fixedly connected to the top of the mold, the stator core is sleeved with the column, the trapezoidal block is adapted to the limit groove, and the outer surface of the trapezoidal block is in contact with the inner wall of the limit groove. Since the trapezoidal block slides in the limit groove, it limits the splint, so that the splint can move in a straight line and avoid shaking.

[0008] Furthermore, a threaded groove is provided at the center of the push block, and a threaded rod is threadedly connected to the inner wall of the threaded groove. The top of the threaded rod passes through the column and extends to the outside. The outer surface of the threaded rod is rotatably connected to the inner wall of the column. When the threaded rod rotates clockwise, the push block moves upward, and when the threaded rod rotates counterclockwise, the push block moves downward.

[0009] Furthermore, a turning handle is fixedly connected to the top of the threaded rod, and the bottom of the threaded rod is rotatably connected to the bottom of the inner wall of the cavity. A plurality of protrusions are fixedly connected to the outer surface of the push block, and the outer surface of the protrusion contacts the inner wall of the limiting groove, and the bottom of the protrusion contacts the surface of the trapezoidal block. The side of the trapezoidal block close to the protrusion is set as an inclined surface. Since the side of the trapezoidal block close to the protrusion is set as an inclined surface, when the protrusion moves downward, it will push the trapezoidal block, thereby driving the splint to expand.

By setting the stabilizing rod, specifically by turning the handle counterclockwise, the push block drives the protrusion to move upward, thereby canceling the pushing of the trapezoidal block, and the clamping plate is slowly reset under the action of the spring elasticity, which is convenient for the next use, and after the clamping plate is contracted and reset, it is convenient to place the stator core next time.

[0011] Furthermore, the outer surface of the limit block contacts the inner wall of the limit hole, the left side of the spring is fixedly connected to the right side of the limit block, the right side of the spring is fixedly connected to the inner wall of the limit hole, and the side of the clamp away from the column contacts the inner wall of the stator core. The limit block is used to limit the movement of the stabilizer bar and facilitates the squeezing of the spring, which can drive the clamp to reset under the action of elasticity.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model sets an adjustment component. Specifically, after the stator core is placed on the mold, the handle is turned clockwise to drive the threaded rod to rotate, and the push block drives the protrusion to push the trapezoidal block, and the trapezoidal block drives the clamping plate to move together, and several clamping plates will expand at the same time, so that stator cores of different sizes can be clamped and fixed, so there is no need to replace the mold, reducing the labor of the staff and reducing the cost of using the mold.

[0014] 2. The utility model sets a stabilizing rod, specifically, by turning the handle counterclockwise, the push block drives the protrusion to move upward, thereby eliminating the need to push the trapezoidal block, and the clamping plate is slowly reset under the action of the spring elasticity, which is convenient for the next use. After the clamping plate is retracted and reset, it is convenient to place the stator core next time.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
