DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. For ease of description, it is assumed that in the entire device, the direction of the gear is forward and the direction of the gear is backward.

[0031] like Figures 1 to 11 As shown, the present invention includes a gear conveying device, an ultrasonic cleaning device, a roller brush, a high-pressure nozzle 10 and a drying device 12.

[0032] A first conveyor belt 1 is provided at the front end of the device, the gear 2 to be cleaned is placed on the first conveyor belt 1, and the gear 2 is conveyed backwards through the first conveyor belt 1.

[0033] The ultrasonic cleaning device comprises a water tank 3 and an ultrasonic generator. The water tank 3 is located below the rear end of the first conveyor belt 1. When the gear 2 moves to the rear end of the first conveyor belt 1, the gear 2 will fall backward from the rear end of the first conveyor belt 1 and fall into the water tank 3, and then ultrasonic cleaning will begin, and the gear 2 will be cleaned in the water tank 3 by the ultrasonic action.

[0034] A second conveyor belt 4 is provided in the water tank 3. The second conveyor belt 4 may be a single conveyor belt or a group of conveyor belts formed by connecting multiple conveyor belts end to end. The front portion of the second conveyor belt 4 is located at a lower position in the water tank 3. After the gear 2 falls into the water tank 3, it falls on the second conveyor belt 4, and the gear 2 is driven to move backwards by the second conveyor belt 4.

[0035] The second conveyor belt 4 has an inclined section in the water tank 3, and the inclined angle is such that when two gears 2 are stacked together, the upper gear 2 will slide downward. The second conveyor belt 4 is provided with a series of blocks 13, which support the gear 2 to prevent it from sliding down. The inclined section and the block 13 ensure that the gears 2 are transported backward and upward one by one, avoiding the problem of stacking and transporting two or more gears 2.

[0036] The roller brush comprises an upper roller brush 5, a lower roller brush 8 and a side roller brush 9. The rear half of the second conveyor belt 4 is horizontal, and an upper roller brush 5 is arranged above the rear half of the second conveyor belt 4. When the gear 2 passes under the upper roller brush 5, the upper surface of the gear 2 is brushed by the upper roller brush 5. The upper roller brush 5 is provided with a water outlet 14 to flush the gear 2 while rolling the brush.

[0037] Behind the second conveyor belt 4 is a work surface, on which a positioning device 7 and a gear grabbing device 6 are respectively provided. The positioning device 7 comprises two cylinders 15 or electric push rods, and the piston rods of the cylinders 15 or electric push rods are respectively provided with V-shaped devices 16, such as Figure 4 As shown, the two V-shaped devices 16 are relatively symmetrically arranged. Figure 4 As shown in a, when the gear 2 moves to between the positioning devices 7, the two V-shaped devices 16 are pushed toward the middle at the same time, pushing the gear 2 to move to the center position between the two V-shaped devices 16, as shown in FIG. Figure 4As shown in b, each gear 2 can be pushed to an accurate position through the positioning device 7, so that the gear grasping device 6 can grasp the gear 2.

[0038] like Figure 5-11 As shown, the gear grabbing device includes a plurality of claws 26, preferably three claws 26, each claw 26 includes a vertical claw portion 25 and a horizontal slide rail portion 21, and the three claws 26 are radially distributed around the axis of the gear grabbing device 6. The claw portion 25 includes a thick section 22 and a thin section 24, wherein the thick section 22 is on the top and the thin section 24 is on the bottom. The lower ends of the thin section 24 and the thick section 22 are each provided with an outer convex edge 23 structure, and the gear 2 is clamped by the outer convex edge 23 structure to prevent it from falling. Figure 7 As shown, when in use, the claw 26 is inserted into the central hole of the gear 2, and then the three claws 26 are spread open to pick up the gear 2. The thin section 24 can be inserted into the hole of the small gear to pick up the smaller gear; the thick section 22 can be inserted into the hole of the large gear. The thick section 22 can withstand greater gravity and is used to pick up the larger gear, so it can adapt to gears 2 of different specifications.

[0039] like Figure 8 As shown, the claws 26 are mounted on a claw mounting frame 31, and the claw mounting frame 31 is provided with a horizontal slideway matching the slide rail portion 21 of the claw, so that the claws 26 can slide along the slideway, thereby realizing the opening and closing of the three claws 26. Figure 5 As shown, a vertical slide bar 19 is provided above the claw 26, and the vertical slide bar 19 is located at the axis of the gear grabbing device 6. The vertical slide bar 19 is connected to each claw 26 through a connecting rod 20, and the vertical slide bar 19 pushes and pulls the claw 26 through the connecting rod 20 to drive the claw 26 to move. The vertical slide bar 19 is driven by the claw motor 17.

[0040] like Figure 6 As shown, the vertical slide bar 19 includes an outer cylinder 29 and an inner cylinder 28, wherein the inner cylinder 28 is located inside the outer cylinder 29. A spring 30 is provided between the outer cylinder 29 and the inner cylinder 28, and the inner cylinder 28 pushes and pulls the outer cylinder 29 up and down through the spring 30. A switch 18 is provided between the inner cylinder 28 and the outer cylinder 29. When the inner cylinder 28 moves downward to a certain position along the outer cylinder 29, the switch 18 is triggered to stop the rotation of the claw motor 17, thereby maintaining the spring 30 at a certain deformation amount, so that the outer cylinder 29 is subjected to a certain thrust. Figure 7 As shown in FIG. 3 , for the pinion, the movement range of the claw 26 is small, the connecting rod 20 tends to be vertical, and the horizontal force exerted by the vertical slide bar 19 on the claw 26 through the connecting rod 20 is small, thereby preventing the thin section 24 of the claw 26 from being damaged; Figure 7As shown in FIG. d, for the large gear 2, the claw 26 has a large movement range, the connecting rod 20 tends to be horizontal, and the vertical slide bar 19 exerts a large horizontal force on the claw 26 through the connecting rod 20, so that the claw 26 can generate a large force on the gear 2, so as to firmly fix the large gear with a large weight. The inner cylinder 28 is driven by the corresponding claw motor 17 through the screw 27 structure.

[0041] like Fig. 9 , 10 As shown, the claw mounting frame 31 is installed on the rotating bracket 32, and a vertical sliding structure is provided between the claw mounting frame 31 and the rotating bracket 32, so that the claw mounting frame 31 can move up and down along the rotating bracket 32, thereby driving the claw 26 to move up and down.

[0042] The rotating bracket 32 ​​is mounted on the outer bracket 36. The outer bracket 36 is connected to the rotating bracket 32 ​​via a seat ring 35, and the rotating bracket 32 ​​can rotate in the outer bracket 36 through the action of the seat ring 35. The outer bracket 36 is provided with a rotating motor 33, and mutually meshing bevel gear pairs 34 are respectively provided between the rotating bracket 32 ​​and the rotating motor 33. The rotating motor 33 drives the rotating bracket 32 ​​to rotate through the bevel gear pair 34, and then drives the gear 2 to rotate, so that the side roller brush 9 can clean the side of the gear 2.

[0043] like Fig.11 As shown, there are a plurality of gear grabbing devices 6, and the outer bracket 36 of the gear grabbing device 6 is installed on a track 37, so that the gear grabbing device 6 can move along the track 37. The track 37 is in the shape of a runway, and the gear grabbing device 6 rotates along the track 37.

[0044] The positioning device 7 is provided with a lower roller brush 8 and a side roller brush 9 behind it, which are used to wash the lower surface and the side of the gear 2. When the gear grabbing device 6 carries the gear 2 to the side roller brush 9, the gear grabbing device 6 stops moving backwards, and the gear grabbing device 6 drives the gear 2 to rotate at least one circle, so that the side roller brush 9 can wash the side of the gear 2. The lower roller brush 8 and the side roller brush 9 are provided with water outlets, respectively, so that the gear 2 can be washed while rolling.

[0045] A high-pressure nozzle 10 is provided behind the roller brush to perform high-pressure washing on the gear 2 through high-pressure and high-speed water flow.

[0046] A third conveyor belt 11 is provided behind the high-pressure nozzle 10, and the third conveyor belt 11 is a metal mesh belt. The gear grabbing device 6 places the gear 2 at the front end of the third conveyor belt 11, and the gear 2 moves backward with the third conveyor belt 11. A drying device 12 is provided at the third conveyor belt 11, and the gear 2 is dried by the drying device 12 to prevent the gear 2 from rusting.

[0047] It should be noted that the specific embodiments of the present invention have been described in detail.
