Description

Technical Field

[0001] The invention relates to the technical field of integrated processing before brazing of a passive disk, and in particular to an intelligent feeding and pressing device for a passive disk. Background Art

[0002] The passive disc plays a key role in the transmission system. It cooperates with the active disc to transmit power and ensure the normal operation of the mechanical equipment. In chain saws and lawn mowers, the passive disc interacts with the active disc to transmit the power of the engine to the saw chain or blade to achieve the cutting function. The passive disc is composed of a small gear and a passive disc surface.

[0003] At present, the assembly, press-fitting and paste-dispensing processes of passive disks before brazing need to be completed with the help of manual labor in different processing workshops. Such assembly line production will cause high labor intensity and prone to omissions. Once an omission occurs, the defective rate of the passive disk will increase. In summary, there is currently a lack of intelligent processing equipment that does not require manual labor and can perform passive disk assembly, press-fitting, paste-dispensing and transportation to brazing equipment in an integrated manner.

After the adjustment is completed, the passive disk is immediately put back into the fixture and transferred to the fifth station with the fixture for accurate paste application. That is, it is convenient to quantitatively apply solder paste between two adjacent teeth of the pinion. It not only has a vertical flipping effect, but also can rotate horizontally to improve the paste application accuracy, thereby improving the automation degree of passive disk processing.

[0057] It should be noted that the first gear transmission assembly 12, the first push plate lift 21, the first telescopic member 23, the second telescopic member 25, the first electric clamp 26, the second push plate lift 31, the third telescopic member 33, the fourth telescopic member 35, the second electric clamp 36, the hydraulic cylinder 42, the fifth telescopic member 51, the servo motor 52, the third electric clamp 53, the sixth telescopic member 55, the second gear transmission assembly 58, the electromagnet 59, the visual detection member 591, the seventh telescopic member 62, the ointment dispensing gun 64, the metering pump and the six-freedom robotic arm are all electrically connected to the controller, and the controller is shown unnumbered in the figure.

[0058] In a further optimization of the embodiment of the present invention, a universal wheel is provided at the bottom of the frame and a locking assembly is provided on the universal wheel, which is not shown in the figure.

[0059] The workflow of the present invention is:

[0060] First, small gears are placed in batches on the first push plate elevator 21, and passive disc surfaces are placed in batches on the second push plate elevator 31. Then, the two push plate elevators can make the small gears and the passive disc surfaces orderly and equidistantly transported along their respective conveying channels. At this time, the small gears and the passive disc surfaces are in an inverted state. The push plate elevator belongs to the prior art and its working principle is not described here.

[0061] Then, when the pinion gear is transported to the end of the conveying channel of the first push plate elevator 21, it will be clamped by the first electric clamp 26. The inward setting of the first clamping plate 27 can improve the clamping effect and facilitate the subsequent partial entry of the first clamping plate 27 into the fixture to accurately place the pinion gear into the gear placement groove of the first station fixture. It should be noted that after the pinion gear is placed in the gear placement groove 162, the step on its bottom surface is higher than the gear placement groove 162;

[0062] Then the controller controls the first gear transmission assembly 12 to operate so that the turntable 13 can rotate at a uniform speed and equal angles, and then the fixture 16 at the first station will move to the second station. At this time, the second electric clamp 36 cooperates with the second clamping plate 37 to clamp a passive disk surface and accurately place it in the disk surface placement groove 161. Similarly, after the passive disk surface is placed in the disk surface placement groove 161, its top is higher than the upper surface of the fixture 16, and at this time, a set of passive disks can be automatically assembled;

[0063] After the passive disk is assembled, the jig 16 will move to the third station. At this time, the hydraulic cylinder 42 drives the pressure head 45 to descend and then act on the middle area of ​​the disk surface. At this time, the jig 16 will move downward to compress the spring 15. At the same time, the connecting roller 17 slides with the inside of the guide sleeve 14, and then the limit plate 18 will move downward. When the limit plate 18 contacts the support platform 46, the hydraulic cylinder 42 stops moving downward, so that the downward movement range can be limited (it should be noted that the upper limit of the pressure of the hydraulic cylinder is also pre-set). Then the hydraulic cylinder 42 drives the pressure head 45 to move up slowly. At this time, the jig 16 is reset under the action of the spring 15. At this point, the pinion and the passive disk surface are automatically pressed at the third station.

[0064] Then the jig 16 moves to the fourth station. Initially, the fifth telescopic member 51 drives the third electric clamp 53 to move to a position higher than the jig 16 and the third electric clamp 53 is arranged horizontally. Then the controller controls the fifth telescopic member 51 to move down to a preset height and then cooperates with the contraction of the third electric clamp 53 to clamp the passive disk surface through the V-shaped plate 54, and then drives the passive disk surface and the pinion gear to move up away from the jig 16 to a height that does not affect the flipping. Then the controller controls the servo motor 52 to work so that the passive disk surface can be rotated 180 degrees in coordination with the pinion gear (during the rotation process, the electromagnet and the visual detection component are moved away from the passive disk under the action of the sixth telescopic member so as not to hinder its rotation).

[0065] After the rotation is completed, the sixth telescopic member 55 drives the mounting rod 56 to move downward so that the electromagnet 59 contacts the upper surface of the pinion gear. At the same time, the electromagnet 59 is controlled to be energized to achieve the adsorption of the pinion gear. After the adsorption is completed, the third electric clamp 53 releases the clamping of the passive disk surface, and the visual detection member 591 can then take a picture to identify the current position of the pinion gear, and transmit a photo of the fixed angle placement position of the pinion gear in the controller in advance. If the two do not match, the controller will then control the second gear transmission assembly 58 to operate to achieve the horizontal rotation of the pinion gear and the passive disk surface. When the angular position of the pinion gear after rotation is consistent with the position in the pre-transmitted picture, it will stop rotating immediately. At this time, the sixth telescopic member 55 moves downward to allow the passive disk to be put back into the fixture 16 of the fourth station, and the electromagnet is immediately controlled to be powered off to release the adsorption, and then the electromagnet is away from the fixture without affecting the subsequent rotation of the fixture.

[0066] Then the jig 16 continues to rotate and then moves to the fifth station. At this time, the seventh telescopic member 62 drives the paste gun 64 to move down to a preset height and cooperates with the metering pump to quantitatively apply solder paste between two adjacent teeth of the pinion. After the paste is applied, the jig 16 continues to rotate to the sixth station. Then, the six-degree-of-freedom mechanical arm 7 cooperates with the gear clamp to transfer the passive disk after the press-fitting and paste application in the jig 16 to the subsequent brazing equipment for brazing process. The brazing process belongs to the prior art and the principle description is not given. It should be noted that when the passive disk in the jig at the sixth station is clamped, it will not contact the solder paste that has been applied, and the passive disk is higher than the height of the jig.

[0067] Through the above six steps, the assembly, pressing, paste application and unloading processes of the passive disk can be automatically completed in six stations in succession without manual intervention. Each jig 16 can complete multiple processing before brazing of a passive disk by rotating one circle, so that the continuous loading, assembly, pressing, paste application and unloading transfer processing flow of the passive disk can be realized, and it is not easy to have omissions, and the degree of automation is significantly improved;

[0068] On this basis, the buffer reset component cooperates with the support platform 46 to reduce the pressure on the turntable 13 during the press-fitting process of the pinion and the passive disk surface, thereby extending the service life of the turntable 13 without affecting the normal rotation and accuracy of the turntable 13. In addition, after completing the press-fitting and the 180-degree turning of the passive disk as a whole, it also has the effect of visual inspection of the pinion and fine-tuning the horizontal rotation angle, thereby improving the accuracy of the subsequent soldering paste process. The passive disk has a good automatic paste-pointing effect, which can significantly improve the subsequent brazing effect, that is, while automatically turning the passive disk after press-fitting, its position can be accurately limited to facilitate subsequent paste-pointing.

[0069] In other embodiments, rubber pads are provided on the first clamping plate, the second clamping plate, the V-shaped plate and the support table to reduce the wear of parts during assembly, loading, pressing and transferring, thereby extending the service life of the device.

[0070] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
