[0005] The purpose of the utility model can be achieved through the following technical solutions: a motor rotor conveying structure, the motor rotor includes a shaft body and an iron core arranged on the shaft body, the conveying structure includes a frame and a chain conveyor line arranged on the frame, the chain conveyor line includes two ring chains arranged side by side, and is characterized in that a circle of support plates distributed along the traveling direction of the ring chains is horizontally provided above the chain conveyor line, the length of the support plate extends along the distribution direction of the two ring chains, and the two ends of the support plate are respectively fixed to the two ring chains; support blocks are fixed on the top surfaces of both ends of the support plate, and the support blocks are penetrated by notch grooves for upwardly supporting the ends of the shaft body along the distribution direction of the two ring chains; a rubber pad is flattened and fixed on the top surface of the middle of the support plate, and a positioning groove is provided on the top of the rubber pad along the distribution direction of the two ring chains, and the cross-section of the positioning groove is an arc shape matching the outer wall of the iron core.

[0006] When in use, the rotor is set horizontally. At this time, the two ends of the shaft are supported in the corresponding two notched grooves respectively, and the lower side of the iron core is wrapped in the positioning groove and forms a large friction, thereby limiting the sliding of the rotor in the axial direction, so that the conveying structure can accurately and smoothly convey the rotor to the set position, with the advantages of simple structure and smooth transportation.

[0007] In the aforementioned motor rotor conveying structure, the endless chain is equipped with L-shaped connecting plates. These connecting plates consist of horizontal supports and vertical connectors.

[0010] In the aforementioned motor rotor conveying structure, a vertically positioned protrusion is formed on the top surface of the support plate. A socket that mates with the protrusion is provided on the bottom surface of the rubber pad, and the protrusion is locked into the socket. The combination of the protrusion and the socket further positions the rubber pad in the axial direction, enhancing its positioning stability and strength.

[0011] In the above-mentioned motor rotor conveying structure, the protruding column is a frustum-shaped structure to enhance the installation accuracy of the rubber pad.

At this time, the two ends of the shaft are supported in the corresponding two notched grooves, and the lower side of the iron core is wrapped in the positioning groove and forms a large friction, thereby limiting the sliding of the rotor in the axial direction, so that the conveying structure can accurately and smoothly convey the rotor to the set position, with the advantages of simple structure and smooth transportation.

[0015] 2. With the cooperation of the boss and the socket, the rubber pad can be further positioned in the axial direction, thereby enhancing the positioning stability and strength of the rubber pad. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figure 1 As shown, in the motor rotor conveying structure, the motor rotor 1 includes a shaft 1a and an iron core 1b mounted on the shaft 1a. The motor rotor conveying structure includes a frame 2 and a chain conveyor 3 mounted on the frame 2. The chain conveyor 3 is an existing product, and its structure is not described in detail here. The chain conveyor 3 includes two annular chains 3a arranged side by side. In this case, the axes of the annular chains 3a are arranged horizontally and extend along the distribution direction of the two annular chains 3a.

[0022] Specifically,

[0023] like Figures 1 to 3 As shown, a circle of support plates 4 is horizontally arranged above the chain conveyor line 3, distributed along the direction of travel of the two ring chains 3a. The length of the support plates 4 extends along the distribution direction of the two ring chains 3a, and the two ends of the support plates 4 are respectively fixed to the two ring chains 3a. Support blocks 5 are fixed to the top surfaces of both ends of the support plates 4, and the support blocks 5 are penetrated with notches 5a along the distribution direction of the two ring chains 3a for upward support of the ends of the shaft body 1a; a rubber pad 6 is flatly laid and fixed on the top surface of the middle part of the support plate 4, and the top of the rubber pad 6 is provided with a positioning groove 6a extending along the distribution direction of the two ring chains 3a, and the cross-section of the positioning groove 6a is an arc shape that matches the outer wall of the iron core 1b. Preferably, the notch 5a is a trapezoidal shape that matches the end of the shaft body 1a.

[0024] When in use, the rotor is arranged horizontally. At this time, the two ends of the shaft body 1a are supported in the corresponding two notched grooves 5a respectively, and the lower side of the iron core 1b is wrapped in the positioning groove 6a and forms a large friction, thereby limiting the sliding of the rotor in the axial direction, so that the conveying structure can accurately and smoothly convey the rotor to the set position, with the advantages of simple structure and smooth transportation.

[0025] In this embodiment,

[0026] like Figure 2 and Figure 3As shown, the support plates 4 are positioned as follows: An L-shaped connecting plate 3b is attached to the endless chain 3a. The connecting plate 3b consists of a horizontal support body 3b1 and a vertical connector. Each end of each support plate 4 corresponds to at least one connecting plate 3b, and the ends of the support plates 4 are pressed against and fixed to the corresponding support body 3b1. This design strengthens the support and positioning of the support plates 4, ensuring smoother rotor transport. Furthermore, the endless chain 3a includes outer link plates 3c, with the connecting plates 3b integrally formed with the corresponding outer link plates 3c. This not only facilitates assembly but also provides more stable support for the support plates 4.

[0027] In actual products, each outer link plate 3c is provided with the above-mentioned connecting plate 3b; the connecting plate 3b and the corresponding support plate 4 are fixed together by vertically arranged screws, which has the advantages of simple structure and easy assembly.

[0028] The rubber pad 6 is bonded and fixed on the support plate 4. Figure 3 As shown, the top surface of the support plate 4 is also formed with a vertically positioned protrusion 4a. The bottom surface of the rubber pad 6 is provided with a socket that matches the protrusion 4a, and the protrusion 4a is firmly locked into the socket. The cooperation between the protrusion 4a and the socket further positions the rubber pad 6 in the axial direction, enhancing its positioning stability and strength. The protrusion 4a is preferably a truncated cone structure to enhance the installation precision of the rubber pad 6.

[0029] Furthermore, each support plate 4 is provided with at least two bosses 4a, and the multiple bosses 4a on the same support plate 4 are distributed along the length direction of the support plate 4. The number of the sockets and the bosses 4a are the same and their positions correspond one to one.
