It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.

[0032] Referring to Figures 1 to 8 As shown, the present invention provides an automatic press-fitting device for a cylinder circlip, including a circlip feeding mechanism 1, a circlip handling mechanism 2 disposed below the circlip feeding mechanism 1, a compression channel guiding mechanism 3 disposed outside one end of the circlip handling mechanism 2, a circlip manipulator 4 disposed above the circlip handling mechanism 2 and the compression channel guiding mechanism 3, and a cylinder barrel bearing mechanism 5 disposed below the compression channel guiding mechanism 3; the circlip handling mechanism 2 is used to successively transport the circlips on the circlip feeding mechanism 1 to the picking position, and a position detection component 9 is provided at the picking position for detecting whether the circlip handling mechanism 2 transports the circlip to the picking position; specifically, the position detection component 9 adopts an opposed fiber optic module. The circlip manipulator 4 is used to pick the circlip on the circlip handling mechanism 2 and punch the circlip into the cylinder barrel 10 on the cylinder barrel bearing mechanism 5 through the compression channel guiding mechanism 3.

[0033] In the present invention, the external air pump is the source of power.

[0034] Continuing to refer to Figure 2, the circlip feeding mechanism 1 and the circlip handling mechanism 2:

[0035] The circlip feeding mechanism 1 includes a feeding mounting frame 11 and a circlip rod 12 mounted on the feeding mounting frame 11. The circlip rod 12 is arranged in the vertical direction, and the circlip rod 12 is connected to the feeding mounting frame 11 through at least one connecting rod 13. In a specific embodiment, the upper and lower ends of the circlip rod 12 are respectively connected to the feeding mounting frame 11 through a connecting rod 13, which is more conducive to the stable installation of the circlip rod 12. When the circlip is sleeved on the circlip rod 12, the opening of the circlip faces the connecting rod 13 to prevent the connecting rod 13 from interfering with the circlip feeding.

[0036] A height adjustment hole is provided at the connection between the connecting rod 13 and the feeding mounting frame 11, and the connecting rod 13 is fixed in the height adjustment hole through an adjustment locking block. Specifically, the height adjustment hole is set as a waist-shaped hole, and the waist-shaped hole is opened in the vertical direction. Providing a height adjustment hole on the circlip feeding mechanism 1 can facilitate adjusting the height of the circlip rod 12 according to circlips of different thicknesses, enhancing versatility.

[0037] The circlip handling mechanism 2 includes a circlip handling block 21 and a circlip feeding cylinder 22 drivingly connected to the circlip handling block 21. A material groove capable of accommodating a circlip is provided at the top of the circlip handling block 21. The groove depth of the material groove is less than the thickness of a circlip to facilitate the circlip suction nozzle 41 to pick up the circlip. The distance between the lower end surface of the circlip rod 12 and the bottom of the material groove is greater than the thickness of a circlip but less than twice the thickness of a circlip, so as to ensure that only one circlip is removed from below the circlip rod 12 by the circlip handling mechanism 2 each time. In a specific embodiment, when the thickness of a certain type of circlip is 1 mm, the groove depth of the material groove is set to 0.8 mm. When the first circlip at the lower end of the circlip rod 12 falls into the material groove, the upper surface of the first circlip is 0.2 mm higher than the upper surface of the material groove. When the second circlip falls on the upper surface of the first circlip, the lower end surface of the circlip rod 12 is 0.2 mm - 0.5 mm lower than the upper surface of the second circlip, so as to ensure that only one circlip is removed from below the circlip rod 12 by the circlip handling mechanism 2 each time, realizing the one-by-one feeding of circlips.

[0038] When it is necessary to press a certain type of circlip into the cylinder barrel 10, first replace different circlip rods 12 and circlip handling blocks 2 (material grooves matching the circlip diameter) according to the circlip diameter, and adjust the relative distance between the lower end surface of the circlip rod 12 and the bottom of the material groove (i.e., adjust the height of the circlip rod 12) according to the thickness of the circlip.

[0039] The working process is as follows:

[0040] 1) The circlip feeding cylinder 22 extends, the circlip handling block 21 moves to directly below the circlip rod 12, and a circlip enters the material groove of the circlip handling block 21;

[0041] 2) The circlip feeding cylinder 22 retracts, and the circlip handling block 21 and the circlip retract to the material taking position of the circlip manipulator 4 at the same time;

[0042] 3) The in-place detection component 9 detects the presence or absence of the circlip. When it senses that there is a circlip at the material taking position, it waits for the next mechanism to act.

[0043] Continue to refer to Figure 3 、 8 the compression channel guiding machine 3 and the positioning mechanism 8:

[0044] The compression channel guiding mechanism 3 includes a stamping and pressing-down module 31 and a first translation driving module 32 for driving the stamping and pressing-down module 31 away from above the cylinder bearing mechanism 5; the stamping and pressing-down module 31 includes a lower pressing plate 311, a moving frame 312 arranged below the lower pressing plate 311, and a plurality of pressing-down guiding modules 313 arranged on the lower pressing plate 311 and the moving frame 312; a circlip compression channel 314 is arranged on the lower pressing plate 311 for the circlip on the circlip manipulator 4 to pass through; the circlip compression channel 314 is detachably embedded on the lower pressing plate 311, and when it is necessary to replace the circlip with different diameters for pressing, it is convenient to replace the circlip compression channel 314.

[0045] The pressing-down guiding module 313 includes a guide post and a guide sleeve arranged on the moving frame 312; a buffer spring is also sleeved on the guide post between the lower pressing plate 311 and the guide sleeve, and the buffer spring is used to prevent the circlip manipulator 4 from damaging the cylinder 10 to be pressed when stamping the circlip.

[0046] The first translation driving module 32 includes a first slide rail and slider assembly arranged at each bottom of both sides of the moving frame 312 and a first driving cylinder drivingly connected to the moving frame 312. The first slide rail and slider assembly is arranged from the end where the circlip handling mechanism 2 is located to the end where the cylinder bearing mechanism 5 is located. The first driving cylinder drives the moving frame 312 to move along the first slide rail and slider assembly, so that the stamping and pressing-down module 31 can move away from above the cylinder bearing mechanism 5, facilitating manual placement of the cylinder 10 to be pressed onto the cylinder bearing mechanism 5.

[0047] There are also positioning mechanisms 8 arranged on the opposite outer sides of the compression channel guiding mechanism 3; the positioning mechanism 8 includes a positioning rod 81 and a positioning driving cylinder 82 for driving the positioning rod 81; a positioning slot matching the shape of the end of the positioning rod 81 is opened on the side end face of the compression channel guiding mechanism 3, and the positioning slot is opened on the outer side wall of the moving frame 312.

[0048] The working process is as follows:

[0049] 1) The positioning driving cylinder 82 drives the positioning rod 81 to retract, releasing the limit on the compression channel guiding mechanism 3;

[0050] 2) The first translation driving module 32 drives the stamping and pressing-down module 31 to retract, and the stamping and pressing-down module 31 moves away from above the cylinder bearing mechanism 5, facilitating manual placement of the cylinder 10 onto the cylinder bearing mechanism 5;

[0051] 3) The first translation driving module 32 drives the stamping and pressing-down module 31 to move above the cylinder bearing mechanism 5, and the positioning driving cylinder 82 drives the positioning rod 81 to extend, repositioning the stamping and pressing-down module 31.

[0052] Continue to refer to Figures 4 to 6 , the circlip manipulator 4:

[0053] The circlip manipulator 4 includes a circlip suction nozzle 41, a second translation driving module 42 for driving the circlip suction nozzle 41 to translate, a first lifting driving module 43 for driving the circlip suction nozzle 41 to lift, and a stamping driving module 44 for driving the circlip suction nozzle 41 to stamp the circlip.

[0054] The first lifting driving module 43 includes a pressing-down cylinder and two second slide rail-slider assemblies; the second translation driving module 42 includes a second driving cylinder and two third slide rail-slider assemblies. Specifically, the second driving cylinder uses a rodless cylinder; the stamping driving module 44 includes a stamping driving cylinder.

[0055] The circlip manipulator 4 further includes a first manipulator mounting frame and a second manipulator mounting frame. The circlip suction nozzle 41 is provided at the middle bottom of the first manipulator mounting frame. The outer sides of the opposite ends of the first manipulator mounting frame are respectively connected to the inner side walls of the second manipulator mounting frame via a second slide rail-slider assembly, and the second slide rail-slider assembly is arranged in the vertical direction; the two third slide rail-slider assemblies are respectively installed at the bottom ends of the second manipulator mounting frame, and the third slide rail-slider assembly is arranged along the length direction parallel to the first slide rail-slider assembly. The pressing-down cylinder is provided at the middle top of the second manipulator mounting frame, and the stamping driving cylinder is provided at the middle top of the first manipulator mounting frame.

[0056] The circlip suction nozzle 41 includes a nozzle body 411 and a circlip pressing shaft 412 movably embedded in the nozzle body 411; the circlip pressing shaft 412 is drivingly connected to the stamping driving module 44; the inner diameter of the circlip compression channel 314 is larger than the outer diameter of the circlip pressing shaft 412, so that the circlip pressing shaft 412 can pass through the circlip compression channel 314.

[0057] The nozzle body 411 includes a hollow nozzle cylinder and a plurality of suction hole columns 413 that are spaced apart and protrude inward from the inner wall of the nozzle cylinder; an adsorption hole penetrating to the bottom is formed in each suction hole column 413, a step structure 414 is provided on the bottom end surface of the suction hole column 413, and the inner side of the bottom end surface of the suction hole column 413 is concave to form a lower step. At the same time, a part of each adsorption hole is located on the higher step, and the other part is located on the lower step. When the nozzle body 411 adsorbs the snap ring, the snap ring is located on the lower step, and the step structure 414 plays a role in restricting the position of the snap ring, so that the snap ring will not deviate during press-fitting, improving the efficiency and accuracy of press-fitting. When the snap ring is sucked by the nozzle body 411, the outer circle of the snap ring is located on the lower step of the step structure 414, and the inner circle of the snap ring corresponds to be below the snap ring pressing shaft 412. When the stamping drive module 44 drives the snap ring pressing shaft 412 to press down, the lower end surface of the nozzle body 411 abuts against the upper end surface outside the snap ring compression channel 314. That is to say, the nozzle body 411 and the snap ring pressing shaft 412 are separately designed. When stamping the snap ring, only the snap ring pressing shaft 412 enters the snap ring compression channel 314, while the nozzle body 411 is limited and abuts outside the snap ring compression channel 314.

[0058] When a certain type of snap ring needs to be pressed into the cylinder barrel 10, first replace the snap ring nozzle 41 corresponding to the diameter of the snap ring.

[0059] A guiding and positioning shaft 6 is provided on each of the opposite outer sides of the snap ring nozzle 41, and a guiding and positioning hole 7 matching the guiding and positioning shaft 6 is provided on the lower pressing plate 311. The guiding and positioning shaft 6 is provided at the bottom of the first robot mounting frame, and a copper sleeve is inlaid in the guiding and positioning hole 7. When the snap ring robot 4 presses down, the guiding and positioning shaft 6 corrects the position through cooperation with the guiding and positioning hole 7, and at the same time, the snap ring can be prevented from shaking during stamping, improving the stamping accuracy.

[0060] The working process is as follows:

[0061] 1) The second translation drive module 42 drives the snap ring nozzle 41 to move above the material taking position;

[0062] 2) The first lifting drive module 43 drives the snap ring nozzle 41 to suck the snap ring from the snap ring handling mechanism 2;

[0063] 3) The second translation drive module 42 drives the snap ring nozzle 41 to move above the cylinder barrel bearing mechanism 5, and at the same time, the compression channel guiding mechanism 3 also moves above the cylinder barrel bearing mechanism 5. At this time, the compression channel guiding mechanism 5 is located between the snap ring robot 4 and the cylinder barrel bearing mechanism 5;

[0064] 4) The first lifting drive module 43 drives the first manipulator mounting bracket to drive the circlip nozzle 41 to descend. The guiding and positioning shaft 6 first enters the guiding and positioning hole 7 for position correction, and then the lower end surface of the nozzle body 411 abuts against the upper end surface outside the circlip compression channel 314. The stamping drive module 44 drives the circlip pressing shaft 412 to press the circlip into the slot of the cylinder barrel 10 through the circlip compression channel 314, and the pressing operation is completed.

[0065] Continue to refer to Figure 7 , the cylinder barrel bearing mechanism 5:

[0066] The cylinder barrel bearing mechanism 5 includes a cylinder barrel bearing platform 51 and a height adjustment module 52 for adjusting the height of the cylinder barrel bearing platform 51.

[0067] A cylinder barrel positioning boss is detachably installed at the middle top of the cylinder barrel bearing platform 51 (a groove is provided on the lower end surface of the cylinder barrel 10), so that the cylinder barrel 10 to be press-fitted can be limited on the cylinder barrel positioning boss.

[0068] When it is necessary to press a certain circlip into the cylinder barrel 10, first replace the corresponding cylinder barrel positioning boss of the cylinder barrel 10. According to the different heights of the cylinder barrel 10 itself, rotate the spoke-type handwheel to drive the stepped lead screw to rotate to adjust the upper plane height of the cylinder barrel 10 to be press-fitted, so that the upper planes of the cylinder barrels 10 with different heights can always be kept at the same height, that is, the operation height plane of the cylinder barrels 10 is unified, and other mechanisms do not need to be adjusted correspondingly, realizing fast line change.

[0069] The cylinder barrel bearing mechanism 5 further includes an upper mounting plate provided at the bottom of the cylinder barrel bearing platform 51 and a lower mounting plate provided below the upper mounting plate. The height adjustment module 52 includes a plurality of adjustment guiding columns spaced between the upper mounting plate and the lower mounting plate, a guiding plate sleeved on the adjustment guiding columns, a stepped lead screw connected to the bottom of the guiding plate and arranged through the lower mounting plate, and a spoke-type handwheel connected to the lower end of the stepped lead screw. The guiding plate is provided with a guiding hole corresponding to each adjustment guiding column, and an oil-free bushing is embedded in the guiding hole; the stepped lead screw is installed at the bottom of the guiding plate through a lead screw fixing seat, and a trapezoidal lead screw nut is provided at the position where the stepped lead screw passes through the lower mounting plate.

[0070] The working process of the present invention is as follows:

[0071] 1) The circlip feeding cylinder 22 drives the circlip carrying block 21 to catch a circlip from the lower end of the circlip rod 12 to the material groove, and then drives the circlip carrying block 21 to move so that the material groove moves out from below the circlip rod 12 and reaches the picking position;

[0072] 2) The circlip manipulator 4 moves to the picking position and is located above the material groove. At the same time, the compression channel guiding mechanism 3 retreats away from above the cylinder barrel bearing mechanism 5 to facilitate the operator to place the cylinder barrel 10 to be press-fitted on the cylinder barrel bearing platform 51;

[0073] 3) The first lifting drive module 43 drives the circlip suction nozzle 41 to descend into the material trough to pick up the circlip. After the material picking is completed, the circlip suction nozzle 41 ascends;

[0074] 4) The second translation drive module 42 drives the circlip suction nozzle 41 to move above the cylinder bearing platform 51. At the same time, the compression channel guiding mechanism 3 advances to above the cylinder bearing platform 51;

[0075] 5) The first lifting drive module 43 drives the circlip suction nozzle 41 to descend until the lower end surface of the suction nozzle body 411 coincides with the upper end surface outside the circlip compression channel 314. The stamping drive module 44 drives the circlip pressing shaft 412 to press the circlip into the card slot of the cylinder 10 through the circlip compression channel 314, and the circlip pressing is completed.

[0076] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention.
