[0019] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4The present invention shows a clamp structure for bonding motor stator magnetic tiles, which can significantly reduce labor intensity and improve assembly production efficiency. The clamp structure includes a clamping support fixing frame and a clamping assembly, and each magnetic tile 1 attached to the inner wall of the stator 2 is pressed against the inner wall of the stator 2 at one time through the clamping support fixing frame respectively and simultaneously with the cooperation of the external driving force input by the clamping assembly. The technical solution provided by the present application is provided by setting a clamp structure including a clamping support fixing frame and a clamping assembly, and then each magnetic tile attached to the inner wall of the stator is pressed against the inner wall of the stator at one time through the clamping support fixing frame with the cooperation of the external driving force input by the clamping assembly. It not only solves the technical problem in the prior art that each magnetic tile needs to be clamped and pressed separately by different U-shaped clips, but also adopts the technical solution of the present application, which does not need to be clamped and pressed one by one. Instead, after the pasting is completed, the clamping support fixing frame is pressed on the inner wall of the stator at one time with the cooperation of the external driving force input by the clamping component, so it can significantly reduce labor intensity and effectively improve assembly production efficiency.

[0020] Accordingly, in combination with the actual production situation, in order to improve the operability of the clamp of the present application and improve its convenience of manufacture, the clamping support fixing frame described in the present application includes a support frame 3 and a clamping fixing component, and the clamping fixing component is arranged on the support frame 3 in a radially expandable manner; during the clamping process of the magnetic tile 1, the clamping fixing component arranged in the inner cavity of the stator 2 through the support frame 3 is pressed tightly against the magnetic tile 1 on the inner wall of the stator 2 under the cooperation of the clamping component. The preferred embodiment is that the support frame 3 is composed of a support flange, and the clamping fixing component is arranged axially on one side of the support flange; the clamping fixing component includes a number of clamping springs 4 that are equivalent to the number of magnetic tiles 1 that need to be clamped, and each clamping spring 4 is arranged on one side of the support flange in the circumferential direction through one end of each end to adapt to the position of each magnetic tile 1. More specifically, each clamping spring 4 described in the present application is composed of a circular arc elastic tile. Moreover, in order to improve the effect of pressing each magnetic tile and ensure that the adhesive surface can obtain uniform pressing force to ensure the quality of the bonding of the magnetic tile 1, the diameter of the pressing circular surface formed by the pressing circular arc of each arc-shaped elastic tile in this application is 0.1 to 0.2 mm smaller than the diameter of the inner hole formed by the inner arc surface of each magnetic tile 1 that needs to be pressed; and the pressing circular surface formed by the pressing circular arc of each arc-shaped elastic tile is conical in the axial direction, and the cone ratio is 1:5. In line with this, the clamping assembly described in this application is also composed of a conical expansion core 5, and the cone ratio of the conical expansion core 5 is 1:5. At this time, the conical expansion core 5 is made of a silk wood stick.

[0021] It should be noted that the stator described in the present application is the cylindrical shell described in the background technology.

[0022] In summary, the clamp structure provided by the present application is suitable for assisting the bonding of the stator magnetic tile of the motorcycle starter motor. When bonding the motor magnetic tile, it provides an accurate and stable clamping support for the magnetic tile before the adhesive is cured; after the adhesive is cured, the clamp can be easily removed and reused. Using the clamp, loading and unloading is convenient and quick, greatly improving labor efficiency.

[0023] The technical solution of the present application is further described below through specific embodiments:

[0024] Embodiment 1

[0025] Expansion tube: The material is reinforced nylon 66; according to the number of magnetic tiles required by the stator, the corresponding number of supporting plates is designed. Its outer diameter is similar to the inner arc of the magnetic tile, slightly smaller by 0.1-0.2mm. The inner diameter of the expansion tube is designed as a tapered hole with a cone ratio of 1:5. The friction force is the largest under this cone ratio.

[0026] Expanding core: The material is a silk wooden stick; one end of the expanding core is a standard cone equal to the size of the cone hole of the expanding tube, and the cone ratio is 1:5.

[0027] With the function of cooperation, when the expansion core expands into the expansion tube, the outer diameter of the expansion tube is the largest, thereby providing a stable and lasting supporting force for the magnetic tile, so that it will not be displaced during the curing process of the adhesive.
