Utility Model Content

[0003] In order to solve the above problems, the purpose of the present invention is to provide a wheel shaft riveting machine that reduces labor costs.

[0004] The technical solution adopted by the utility model to solve the problem is: a wheel riveting shaft machine, comprising:

[0005] A frame, wherein a rotatable rotating disk is provided on the frame, a rotating shaft is provided at the center of the rotating disk, a plurality of mold bases are evenly arranged along the circumference of the upper surface of the rotating disk, a mold cavity adapted to the shape of the aluminum sleeve is provided on the upper surface of the mold base, and a loading station, a stamping station and an unloading station are sequentially provided on the frame surrounding the circumference of the wheel disc;

[0006] The punching station is provided with a punching head located above the wheel disc. When the die base rotates to be located at the punching station, the punching head is located directly above the die base.

[0007] The blanking station is provided with an air jet pipe located on the surface of the wheel disc and inside the die base, the air jet pipe is connected to an air pump, the height of the end of the air jet pipe is lower than the height of the die base, and when the die base rotates to the stamping station, the end of the air jet pipe is located below the wheel disc and tilted toward the lower surface of the wheel disc;

[0008] A material guide pipe is provided outside the rotating disk. When the die base rotates to the punching station, the end of the air injection pipe, the die base and the material guide pipe are located in the same straight line;

[0009] A one-way bearing, comprising an inner ring and an outer ring, wherein the rotating shaft is fixedly inserted into the inner ring and a gear is provided on the outer circumference of the outer ring;

[0010] A rack is engaged with the gear, and the rack is connected to a driver that drives the rack to perform reciprocating motion.

[0011] As a further improvement of the above technical solution, the rotating shaft is arranged on the lower end surface of the rotating disk.

[0012] As a further improvement of the above technical solution, the number of the mold bases is six.

[0013] As a further improvement of the above technical solution, the outer peripheral edge of the rotating disk is provided with positioning notches whose number is equal to that of the mold base, the surface of the frame is provided with a telescopic cylinder, and the end of the telescopic cylinder is provided with a positioning pin that is movably engaged in the positioning notch.

[0014] As a further improvement of the above technical solution, the positioning notch is triangular in shape, and the positioning pin is also triangular in shape.

[0015] As a further improvement of the above technical solution, an auxiliary cylinder is provided on the frame, and a pad is provided at the output end of the auxiliary cylinder. The auxiliary cylinder is used to drive the pad to move to the bottom of the rotating disk and be located directly below the punch head.

[0016] The beneficial effect of the present utility model is as follows: in this solution, the worker is located at the loading station and is responsible for placing the aluminum sleeve in the mold cavity of the mold base, and then placing the circular disk body on the aluminum sleeve and making the shaft hole on the circular disk body fit with the aluminum sleeve, and then the driver drives the rack forward, thereby driving the rotating disk to rotate one position through the one-way bearing, and then the driver drives the rack to reset. Since the one-way bearing can only be driven in one direction, the rotating disk will not rotate at this time. As the rotating disc rotates continuously, the die base is moved to the stamping station. At this time, the punch head stamps downward, thereby stamping the aluminum sleeve and the circular disc body into an integrated structure to form a complete wheel disc. Then the rotating disc continues to rotate to the unloading station. At this time, the end of the jet pipe is located below the wheel disc and tilted toward the lower surface of the wheel disc. The end of the jet pipe, the die base and the guide pipe are located in the same straight line. Therefore, the air pump drives the jet pipe to spray instantly, so that the wheel disc on the die base can be blown toward the guide pipe, so that the wheel disc falls into the guide pipe and is collected. In the whole process, only the loading process needs to be performed manually, which saves the labor cost of the stamping and unloading processes. Moreover, due to the accuracy problem of the loading process, if it is replaced by pure automation, the cost will increase significantly. Therefore, the loading process still remains manually operated, so the overall manufacturing cost is relatively low, which is suitable for application in small and micro enterprises.

[0024] Reference Figures 1 to 2 , a wheel shaft riveting machine, comprising:

[0025] A frame 10 is provided with a rotatable rotating disk 20, a rotating shaft 21 is provided at the center of the rotating disk 20, a plurality of mold bases 22 are evenly arranged along the circumference of the upper surface of the rotating disk 20, and a mold cavity adapted to the shape of the aluminum sleeve is provided on the upper surface of the mold base 22. The frame 10 is sequentially provided with a loading station, a stamping station, and an unloading station surrounding the circumference of the wheel disc;

[0026] The punching station is provided with a punching head 30 located above the wheel disc. When the die base 22 rotates to be located at the punching station, the punching head 30 is located directly above the die base 22.

[0027] The blanking station is provided with an air jet 40 located on the surface of the wheel disc and inside the die base 22. The air jet 40 is connected to an air pump. The height of the end of the air jet 40 is lower than the height of the die base 22. When the die base 22 rotates to the punching station, the end of the air jet 40 is located below the wheel disc and tilted toward the lower surface of the wheel disc.

[0028] The material guide pipe 50 is provided outside the rotating disk 20. When the die base 22 rotates to the punching station, the end of the air injection pipe 40, the die base 22 and the material guide pipe 50 are located in the same straight line;

[0029] A one-way bearing 60 , comprising an inner ring and an outer ring, wherein the rotating shaft 21 is fixedly inserted into the inner ring and a gear 61 is provided on the outer circumference of the outer ring;

[0030] The rack 62 is meshed with the gear 61 , and the rack 62 is connected to a driver 63 for driving the rack 62 to perform reciprocating motion.

[0031] In this solution, the worker at the loading station is responsible for placing the aluminum sleeve in the mold cavity of the mold base 22, and then placing the circular disk on the aluminum sleeve and making the axial hole on the circular disk fit with the aluminum sleeve. Then the driver 63 drives the rack 62 forward, thereby driving the rotating disk 20 to rotate one position through the one-way bearing 60, and then the driver 63 drives the rack 62 to reset. Since the one-way bearing 60 can only be driven in one direction, the rotating disk 20 will not rotate at this time. During the continuous rotation of the rotating disk 20, the die base 22 is moved to the stamping station. At this time, the punch head 30 stamps downward, thereby stamping the aluminum sleeve and the circular disk body into an integrated structure to form a complete wheel disk. Then the rotating disk 20 continues to rotate to the unloading station. At this time, the end of the jet pipe 40 is located below the wheel disk and tilted toward the lower surface of the wheel disk, and the end of the jet pipe 40, the die base 22 and the guide pipe 50 are located in the same straight line. Therefore, the air pump drives the jet pipe 40 to spray instantly, so that the wheel disk located on the die base 22 can be blown toward the guide pipe 50, so that the wheel disk falls into the guide pipe 50 and is collected. In the whole process, only the loading process needs to be performed manually, which saves the labor cost of the two processes of stamping and unloading. Moreover, due to the accuracy problem of the loading process, if it is replaced by pure automation, the cost will increase significantly. Therefore, the loading process still remains manually operated, so the overall manufacturing cost is relatively low, which is suitable for application in small and micro enterprises.

[0032] In this solution, the rotating shaft 21 is preferably provided on the lower end surface of the rotating disk 20 .

The surface of the frame 10 is provided with a telescopic cylinder 70, and the end of the telescopic cylinder 70 is provided with a positioning pin 71 that movably engages with the positioning notch 23. When the rotating disk 20 rotates one position, the telescopic cylinder 70 drives the positioning pin 71 toward the outer periphery of the rotating disk 20, so that the positioning pin 71 is engaged in the positioning notch 23, thereby completing the positioning. Preferably, the positioning notch 23 is triangular in shape, and the positioning pin 71 is also triangular in shape.

[0035] For further optimization, an auxiliary cylinder 80 is provided on the frame 10, and a pad 81 is provided at the output end of the auxiliary cylinder 80. The auxiliary cylinder 80 is used to drive the pad 81 to move to the bottom of the rotating disk 20 and be located directly below the punch head 30, so that when the punch head 30 punches downward, the rotating disk 20 can be auxiliary supported by the pad 81, thereby ensuring that the rotating disk 20 will not be pressed downward.
