Description

Technical Field

[0001] The present invention relates to the technical field of transfer equipment, and particularly relates to an automatic transfer device for assembling a motor end cover and a shaft sleeve. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction, or converts electrical energy in one form into electrical energy in another form, and can be mainly divided into a DC motor and an AC motor.

[0003] The motor end cover is the cover of the motor housing, generally divided into a front cover and a rear cover, and is used to fix and support the motor rotating shaft. In order to improve the stability of the motor rotating shaft during rotation, during the production and processing of the motor, a shaft sleeve needs to be installed on the motor end cover. At the same time, during the production and processing process, it is necessary to transfer semi-finished parts to the assembly location. Currently, the motor end covers placed on the transfer rack need to be manually carried to the operating table for assembly operations, which increases the labor intensity of the assemblers and reduces the assembly efficiency. Therefore, we propose an automatic transfer device for assembling a motor end cover and a shaft sleeve to solve the above problems. Summary of the Invention

[0031] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0032] Referring to Figures 1-5 , an automatic transfer device for assembling a motor end cover and a shaft sleeve, including a base 1 and a drive bin 13 fixed to the bottom of the base 1. Universal wheels 2 are provided at the four corners of the bottom end of the base 1. The universal wheels 2 are equipped with a locking mechanism, which is a mechanism for fixing the movement of the universal wheels 2 in the prior art. The device can be easily transported through the universal wheels 2;

[0033] Secondly, a spiral feeding rack 3 is also arranged on the base 1. The spiral feeding rack 3 is vertically installed on the base 1 through a bracket. A protective net 24 can be arranged on the outer side of the spiral feeding rack 3 to prevent the motor end cover from falling. A material receiving box 4 is arranged on one side of the base 1. The material receiving box 4 is located at the sliding-out end of the spiral feeding rack 3. A first conveyor belt 5 is fixed on the material receiving box 4. A guide plate 8 facing the first conveyor belt 5 is also arranged at the bottom sliding end of the spiral feeding rack 3. By arranging the guide plate 8, it is convenient for the motor end cover to slide onto the first conveyor belt 5 for transportation. A second conveyor belt 6 is arranged at the top of the first conveyor belt 5;

[0034] Among them, the second conveyor belt 6 is rotatably connected to the first conveyor belt 5. An electric push rod 7 is arranged at the bottom end of the second conveyor belt 6. One end of the electric push rod 7 is rotatably installed on the extension rack at the outer end of the material receiving box 4, and the telescopic end of the electric push rod 7 is rotatably installed on the second conveyor belt 6. The electric push rod 7 drives the second conveyor belt 6 to rotate on the first conveyor belt 5 to adjust the conveying height of the second conveyor belt 6. A plurality of anti-slip bumps are arranged on the surfaces of both the first conveyor belt 5 and the second conveyor belt 6. By arranging the bumps, the friction force with the motor end cover can be increased, which is convenient for transporting the motor end cover;

[0035] A dial plate 9 is slidably installed on the spiral feeding rack 3. The dial plate 9 is arranged to push the motor end cover on the spiral feeding rack 3 to facilitate its downward sliding for sequential transportation. A telescopic rod 12 is arranged at the axis of the spiral feeding rack 3. The telescopic rod 12 is rotatably installed on the base 1. The top end of the telescopic rod 12 is fixedly connected to the dial plate 9 through a connecting rod 11, and a rotating shaft 14 is fixed to the bottom end of the telescopic rod 12;

[0036] It should be noted that:

[0037] 1. Openings 31 are formed on the inner walls on both sides of the spiral feeding rack 3. Roller wheels 10 are arranged at both ends of the dial plate 9. The roller wheels 10 are installed in the openings 31 to facilitate the downward movement of the dial plate 9;

[0038] 2. The cross-section of the telescopic rod 12 is polygonal, and the number of sections of the telescopic rod 12 is the same as the number of layers of the spiral feeding rack 3. When the dial plate 9 rotates to the lower layer, the telescopic rod 12 can contract, and the dial plate 9 pushes the motor end cover on the spiral feeding rack 3 to facilitate its downward sliding;

[0039] At the same time, the rotating shaft 14 extends into the drive bin 13, and an internal gear ring 15 and a first bevel gear 16 are fixed on the rotating shaft 14. The internal gear ring 15 has tapered teeth, and the internal gear ring 15 and the first bevel gear 16 are concentrically arranged;

[0040] In addition, a screw rod 23 is fixedly and rotatably installed inside the driving bin 13, and a servo motor 18 is arranged on the screw rod 23. There are two screw rods 23, and connecting plates are fixed on both sides of the servo motor 18. The screw rod 23 is threadedly connected to the connecting plates. The screw rod 23 is installed in the driving bin 13 through a mounting frame. The stability of the movement of the servo motor 18 can be improved by arranging the screw rods 23 on both sides. A transmission gear 21 is fixed at one end of the screw rod 23, and the transmission gear 21 is meshed with a driving gear 22 installed on the inner wall of the driving bin 13. The driving gear 22 is driven by an external variable frequency motor.

[0041] Among them, two limit blocks 17 are arranged on the screw rod 23, and the screw rod 23 is rotatably connected with the limit blocks 17, and the limit blocks 17 on both sides limit the moving position of the servo motor 18;

[0042] A half bevel gear 19 and a second bevel gear 20 are fixed to the output shaft of the servo motor 18 . The half bevel gear 19 and the second bevel gear 20 are concentrically arranged. The second bevel gear 20 matches the first bevel gear 16 , and the half bevel gear 19 matches the inner gear ring 15 .

[0043] When the servo motor 18 contacts the limit block 17 on one side, the first bevel gear 16 meshes with the second bevel gear 20, and the inner gear ring 15 and the half-tooth bevel gear 19 are staggered. Conversely, the first bevel gear 16 and the second bevel gear 20 are staggered, and the inner gear ring 15 and the half-tooth bevel gear 19 are meshed. After adjusting the position of the servo motor 18 by the driving gear 22, the two modes of continuous conveying or indirect conveying can be switched at the motor end cover to meet the assembly of different requirements of the motor end cover.

[0044] In this embodiment: the semi-finished motor end cap is placed on the spiral unloading rack 3 for transportation, the device is pushed to the assembly table, the electric push rod 7 is turned on, the second conveyor belt 6 is driven by the electric push rod 7 to rotate on the first conveyor belt 5, and the top height of the second conveyor belt 6 is adjusted so that the conveyed motor end cap can fall onto the assembly table;

[0045] When the motor end cover needs to be continuously transported, the driving gear 22 is opened, and the driving gear 22 drives the screw rod 23 to rotate. When the screw rod 23 rotates, the servo motor 18 is driven to move to the left, so that the second bevel gear 20 is meshed with the first bevel gear 16, and the servo motor 18 is turned on after the meshing. The servo motor 18 drives the second bevel gear 20 to rotate while driving the rotating shaft 14 and the telescopic rod 12 to rotate. The telescopic rod 12 drives the paddle plate 9 to move and paddle the motor end cover, so that the motor end cover slides continuously onto the first conveyor belt 5, so that the motor end cover is continuously transported by the first conveyor belt 5 and the second conveyor belt 6, thereby avoiding the need to carry it and reducing the labor intensity of the assembler;

[0046] When it is necessary to indirectly transport the motor end cover (when some motor end covers need to be assembled with multiple parts, indirect transportation is performed), open the drive gear 22, and the drive gear 22 drives the servo motor 18 to move to the right, so that the first bevel gear 16 and the second bevel gear 20 are staggered, and the inner gear ring 15 is engaged with the half-tooth bevel gear 19. Therefore, when the half-tooth bevel gear 19 rotates and engages with the inner gear ring 15, it can drive the shift plate 9 to move and indirectly shift the motor end cover to meet the assembly requirements of the motor end cover.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
