[0037] The present invention will be further described below in conjunction with specific embodiments, but the protection scope of the present invention is not limited thereto.

[0038] As Figure 1 and 2 shown, the picking mechanism 3 of the present invention for a motorcycle wheel gravity machine works in cooperation with the moving die guiding mechanism 2 in the gravity machine when in use. Among them, the moving die guiding mechanism 2 includes an oil cylinder push plate one 21, an oil cylinder push plate two 22 and a main oil cylinder 23. The main oil cylinder 23 passes through the oil cylinder push plate two 22, and the output shaft 210 of the main oil cylinder is connected to the oil cylinder push plate one 21. The oil cylinder push plate one 21 and the oil cylinder push plate two 22 are connected by a connecting column 24, and are locked with the connecting column 24 through a locking nut 29. The lower end of the connecting column 24 is connected with a moving template 25, and below the moving template 25 is the product 12; lifting guide columns 26 are arranged on both sides of the oil cylinder push plate two 22. Upper nuts 27 and lower nuts 28 are arranged at the upper ends of the lifting guide columns 26. The upper nuts 27 and the lower nuts 28 are separated by a certain distance, and the oil cylinder push plate two 22 is located between the upper nuts 27 and the lower nuts 28, that is, the distance between the upper nuts 27 and the lower nuts 28 is the stroke of the oil cylinder push plate two 22.

[0039] The picking mechanism 3 of the present invention includes a mounting seat 31. The lifting guide columns 26 are connected to the mounting seat 31 through pressing blocks 32, that is, mounting seats 31 are connected to the lower ends of the lifting guide columns 26 on both sides of the oil cylinder push plate two 22. Two guide sleeves 39 are also arranged on the mounting seat 31, and the lifting guide columns 26 are located between the two guide sleeves 39. A clamping block 33 is arranged below the mounting seat 31, that is, there are also two clamping blocks 33, and the positions of the two clamping blocks 33 match the moving template 25, so that the two clamping blocks 33 can just pick up the product 12 below the moving template 25.

[0040] The clamping block 33 is connected to the output shaft 35 of the picking cylinder, and locking blocks 36 are arranged on both sides of the clamping block 33. A guiding groove is formed in the middle of the locking blocks 36, and the clamping block 33 moves in the guiding groove, that is, the clamping block 33 is guided by the locking blocks 36.

[0041] When the mold is opened, the main oil cylinder 23 pushes the first oil cylinder push plate 21 upward, and at the same time drives the second oil cylinder push plate 22 upward, thereby driving the moving template 25 upward. When the second oil cylinder push plate 22 moves to contact the upper nut 27, it will drive the two left and right lifting guide columns 26 upward. At this time, the moving template 25 has moved upward by a distance, which is the distance between the upper nut 27 and the lower nut 28, and this distance can be adjusted according to the height of the installed mold. At this time, the pick-up cylinder 34 of the pick-up mechanism 3 works, and the output shaft 35 of the pick-up cylinder pushes the clamping block 33 to clamp the product from the left and right sides of the product 12 to prevent the product 12 from falling.

[0042] More preferably, the pick-up cylinder 34 in the present utility model is provided with a connecting plate 36. Adjusting screw rods 37 are provided on both sides of the connecting plate 36. One end of the adjusting screw rod 37 is connected to the locking block 36, and the other end of the adjusting screw rod 37 is provided with an adjusting nut 38. The connecting plate 36 is located between the locking block 36 and the adjusting nut 38, and the clamping range of the left and right clamping blocks 33 is adjusted by the adjusting screw rod 37 and the adjusting nut 38.

[0043] As Figures 3 - 5 shown, the pick-up mechanism 3 of the present utility model is used in a motorcycle wheel gravity machine. The gravity machine includes a frame 1, on which a hydraulic block / solenoid valve 10, a cooling mechanism 9, a moving die guiding mechanism 2, a pick-up mechanism 3, a product receiving mechanism 4 and a lower ejecting mechanism 5 are installed. The moving die guiding mechanism 2 is located above the pick-up mechanism 3, the product receiving mechanism 4 is located below the pick-up mechanism 3, and the lower ejecting mechanism 5 is located below the product receiving mechanism 4. The above mechanisms are all operated through an operation box 8. A water receiving tray 6 with a water receiving tray drain port 61 is further provided below the lower ejecting mechanism 5, and the bottom of the water receiving tray 6 is fixed by 4 groups of anchor bolts 7.

[0044] As Figures 6 - 9 shown, the product receiving mechanism 4 in the present utility model includes a second guide rail frame 41. Above the second guide rail frame 41, a first guide rail frame 43 is connected through a second guide rail slider 42, and the first guide rail frame 43 is connected to the second guide rail slider 42 through a second connecting block 412. Above the first guide rail frame 43, a first sliding frame 45 is connected through a first guide rail slider 44, and the first sliding frame 45 is connected to the first guide rail slider 44 through a first connecting block 411. A receiving tray 46 is provided on the first sliding frame 45. A first cylinder 47 is provided on the first guide rail frame 43. The end of the output shaft of the first cylinder 47 is provided with a first cylinder connecting head 48, and the first cylinder connecting head 48 is connected to the first sliding frame 45; a second cylinder 49 is provided on the second guide rail frame 41. The end of the output shaft of the second cylinder 49 is provided with a second cylinder connecting head 410. The second cylinder connecting head 410 is located on the opposite side of the first cylinder connecting head 48, and the second cylinder connecting head 410 is connected to the first guide rail frame 43, so that the first sliding frame 45 and the first guide rail frame 43 move in different directions, expanding the position for receiving products.

[0045] The product receiving mechanism 4 in this utility model is driven by cylinders. A total of 2 cylinders are configured as a whole, enabling the receiving tray 46 to stop at 3 different workstations. Among them, one cylinder driving mechanism, namely cylinder one 47, is configured on the upper layer of the product receiving mechanism 4. When cylinder one 47 moves, the sliding frame one 45 performs a linear motion on the guide rail frame one 43 through the guide rail slider one 44. When the stroke of cylinder one 47 is completed, the receiving tray 46 reaches the designated position A as shown in Figure 7 . The above part constitutes the upper structure of the product receiving mechanism 4. When cylinder one 47 retracts, the receiving tray 46 reaches the standby position B as shown in Figure 8 . One cylinder driving mechanism, namely cylinder two 49, is configured on the lower layer of the product receiving mechanism 4. When cylinder two 49 moves, the guide rail frame one 43 performs a linear motion on the guide rail frame two 41 through the guide rail slider two 42 (i.e., the entire upper mechanism). When the stroke of cylinder two 49 is completed, the receiving tray 46 reaches the designated position C as shown in Figure 9 .

[0046] Furthermore, as shown in Figures 10 - 14 , the lower ejection mechanism 5 in this utility model includes a mold fixing seat 51. A number of cushion columns 516 are provided below the mold fixing seat 51, and the cushion columns 516 are located outside the ejection oil cylinder 55. An ejection plate 52 is provided above the mold fixing seat 51. An ejection clamping seat 53 is provided on the ejection plate 52. A connecting block 54 is provided inside the ejection clamping seat 53. An ejection oil cylinder 55 is provided below the mold fixing seat 51. The output end 517 of the ejection oil cylinder passes through the mold fixing seat 51 and is connected to the ejection plate 52. A number of ejection guide columns 56 are provided below the ejection plate 52. The ejection guide columns 56 pass through the mold fixing seat 51 and move up and down on the mold fixing seat 51.

[0047] The mold includes an upper plate 57 and a lower plate 58. The upper plate 57 is installed on the workbench plate 11, and a product mounting seat 59 is above the upper plate 57. The lower plate 58 is located above the mold fixing seat 51, and the lower plate 58 is connected with a mold ejection plate 510 through a mold guide column 514. A mold connecting part 511 is provided below the mold ejection plate 510. The mold connecting part 511 is inserted into the ejection clamping seat 53 and locked by the connecting block 54. The connecting block 54 is a U-shaped block and is locked with the mold connecting part 511 through a locking screw 515 to prevent the connecting block 54 from disengaging during movement, further increasing the stability of the mold on the lower ejection mechanism 5. A thimble mounting seat 512 is provided above the mold ejection plate 510, and a number of thimbles 513 are provided on the thimble mounting seat 512.

[0048] During operation, the ejector cylinder 55 is driven, and the output shaft 517 of the ejector cylinder pushes the ejector plate 52 to move up and down. The ejector plate 52 is guided by the ejector guide posts 56, eliminating the need for the piston of the cylinder as a guide and avoiding oil leakage from the cylinder. The ejector plate 52 drives the ejector clamping seat 53 and the connecting block 54 to move. At this time, the mold ejection part fixed to the connecting block 54 performs an ejection movement synchronously, that is, the mold ejector plate 510 moves up and down guided by the mold guide posts 514, driving the ejector pin mounting seat 512, and thus driving the ejector pin 513, so that the ejector pin 513 passes through the upper plate 57 to eject the product 12 on the product mounting seat 59.

[0049] In this utility model, the lower ejection mechanism 5 on the device drives the ejection mechanism on the mold to eject the product 12. Through the cooperation of the moving mold guiding mechanism 2 and the picking mechanism 3, the product is clamped below the moving template 25, and by rotating the product receiving mechanism 3 by the operator, the product just falls onto the receiving tray 46, greatly improving the picking efficiency and avoiding product quality problems caused by improper picking.

[0050] For other structures, their connection relationships, and working principles of the motorcycle wheel gravity machine of this utility model except for the moving mold guiding mechanism 2, the picking mechanism 3, the product receiving mechanism 4, and the lower ejection mechanism 5 are common general knowledge in the art, as recorded in the utility model patent with the publication number CN202824540U, and will not be elaborated here.

[0051] The above embodiments are only used to explain the inventive concept of this utility model, rather than limiting the protection scope of the rights of this utility model. Any non-substantive modification of this utility model using this concept shall fall within the protection scope of this utility model.
