Description

Technical Field

[0001] The invention relates to the field of ball cage product processing, and in particular to a production process for window holes of ball cage products. Background Art

[0002] The ball cage is also called "constant velocity universal joint"; it is a key component in the automobile transmission system. The ball cage transfers the engine power from the transmission to the drive wheel to drive the car. The ball cage is mainly composed of an outer wheel, an inner wheel, several steel balls and a cage. The outer wheel is located outside the inner wheel, and the cage is set between the two. The cage is provided with several window holes, and steel balls are rollingly connected in the window holes. Among them, the dimensional accuracy of the cage is the key factor in determining the quality of the ball cage.

[0003] Chinese patent CN201810281991.3 discloses a ball cage retainer processing technology, which places the formed ball cage product on a punching machine to punch rectangular window holes, then mills the edges of the window holes on a milling machine, and then performs carburizing, sandblasting, grinding, cleaning and packaging.

[0004] However, since the front and back sides of the cage are different, it is necessary to manually identify the front and back sides before placing it on the punching machine, and turn the ball cage with the back side facing up, and then punch it with the front side facing up. This is inefficient and requires a lot of manual work. It is easy to miss something during manual operation, resulting in a high scrap rate and the risk of equipment interference and collision. Moreover, in the existing window hole production process technology for ball cage products, generally one worker operates the punching machine and another worker operates two milling machines to achieve the punching and window hole milling processing of the product, which requires more manpower and results in more labor costs. Summary of the invention

[0005] The purpose of the present invention is to provide a production process for window holes of ball cage products to solve the following technical problems:

[0006] How to avoid the high scrap rate caused by the omission of the front and back sides in manual identification and reduce the risk of equipment interference and collision, ensure the processing accuracy of the equipment and extend the service life of the equipment;

[0035] (2) During operation, when the ball cage product to be processed moves to the detection position directly below the corresponding substrate, the photoelectric sensors on each corresponding substrate transmit the measured distance value of the detected product to the external PLC controller. Since the front and back areas of the ball cage product to be processed are different in size and the lengths of the inner and outer diameters, the external PLC controller selects the number of photoelectric sensors with the smallest measurement results. If the number and the corresponding positions of the photoelectric sensors are the same, the front side is facing up; if they are different, the back side is facing up.

[0056] This modular combined production process can be arranged through two groups of positive and negative hand or mirror connection combinations, so that one worker can easily control two connection equipment to perform ball cage window punching and window hole two-plane milling. Compared with the traditional single-function, cluster machine tool layout, it reduces 2-3 workers and can save a lot of labor costs.

[0057] As an embodiment of the present invention, please refer to Figure 2-Figure 4 As shown, the upper material handling platform 1 includes a loading workbench 101, two No. 1 transmission rollers 102, a first motor 103 fixed to the loading workbench 101, a plurality of No. 1 conveyor belts 104 and a plurality of guide components 105;

[0058] The loading workbench 101 is provided with a plurality of transmission grooves; the No. 1 transmission rollers 102 are all rotatably connected in the transmission grooves, and the two ends of the loading workbench 101 are respectively rotatably connected to the No. 1 transmission rollers 102; the No. 1 transmission rollers 102 pass through the transmission grooves in sequence; the output end of the first motor 103 is fixedly connected to one end of one of the No. 1 transmission rollers 102; a plurality of No. 1 conveyor belts 104 are transmission-connected between the two No. 1 transmission rollers 102; the No. 1 conveyor belts 104 correspond to the transmission grooves, and the No. 1 conveyor belts 104 are respectively located in the corresponding transmission grooves; a plurality of guide assemblies 105 are fixedly connected to one end of the loading workbench 101 close to the front and back identification component 2; the guide assemblies 105 correspond to the No. 1 conveyor belts 104, and are located above the No. 1 conveyor belts 104; the guide assemblies 105 are used to guide and arrange the ball cage products to be processed neatly before moving to the front and back identification component 2;

[0059] In order to make the ball cage products to be processed automatically arranged before they are moved to the front and back identification component 2, the ball cage products to be processed are placed on the end of the No. 1 conveyor belt 104 away from the front and back identification component 2; and the top upper surface of the No. 1 conveyor belt 104 is at the same horizontal height as the upper surface of the loading workbench 101, so that the ball cage products to be processed can be conveniently moved on the loading workbench 101 and the No. 1 conveyor belt 104; the first motor 103 is started; the output end of the first motor 103 drives a number of No. 1 conveyor belts 104 to rotate through the No. 1 transmission roller 102; the ball cage products to be processed move toward the front and back identification component 2 on different No. 1 conveyor belts 104 according to their positions, and the guide component 105 arranges the ball cage products to be processed in a single row on the corresponding No. 1 conveyor belt 104, so that the front and back identification of the ball cage products to be processed on each No. 1 conveyor belt 104 can be conveniently performed in sequence;

The number of photoelectric sensors 204 with the smallest measurement result and the corresponding positions of the photoelectric sensors 204 are determined; when the ball cage product to be processed moves to the detection position directly below the corresponding substrate 203, the photoelectric sensors 204 on each corresponding substrate 203 transmit the value of the measured distance to the detected product to the external PLC controller. Since the area size and the inner and outer diameter lengths of the front and back sides of the ball cage product to be processed are different, the external PLC controller selects the number of photoelectric sensors 204 with the smallest measurement result and the corresponding positions of the photoelectric sensors 204. If they are the same, the front side is facing up. If they are different, the back side is facing up.
