[0026] Reference Figures 1 to 4 , an embodiment of the present application provides a one-piece automatic spraying device for track rollers, including a spraying robot 10, a mounting bracket 20, and a lifting mechanism 30 and a plugging mechanism 40 mounted on the top of the mounting bracket 20. The spraying robot 10 is used for multi-point directional spraying to comprehensively spray the rotating track roller 50 on one side. The spraying robot 10 selects an ABB robot;

[0027] The lifting end of the lifting mechanism 30 is connected with a fixing plate 31 for driving the fixing plate 31 to move up and down directionally. A first rotating element 32 is mounted on the fixing plate 31. At the same time, a lead screw 33 extending in the horizontal direction is arranged at the bottom of the fixing plate 31, and guide rails 34 are symmetrically arranged on both sides of the lead screw 33. The lead screw 33 is provided with external threads with opposite rotation directions with the middle as the boundary. In addition, the rotating end of the first rotating element 32 is coaxially connected to the lead screw 33, and the lead screw 33 is respectively sleeved with a first lead screw slider 35 and a second lead screw slider 36 at both ends. At the same time, the first lead screw slider 35 and the second lead screw slider 36 are respectively slidably matched with the guide rails 34. In this way, the first lead screw slider 35 and the second lead screw slider 36 can be driven to approach or move away from each other relatively synchronously based on the sliding fit relationship and the screwing relationship through the first rotating element 32. A first rotating head 351 is arranged on the inner side of the first lead screw slider 35. At the same time, a second rotating element 362 is vertically connected to the outer side of the second lead screw slider 36, and a second rotating head 361 symmetric to the first rotating head 351 and capable of being coaxially driven to rotate by the second rotating element 362 is arranged on the inner side of the second lead screw slider 36. In this way, after the first rotating head 351 and the second rotating head 361 approach each other synchronously and clamp the track roller 50 at both ends, the track roller 50 can be driven to rotate quickly by the second rotating element 362, and cooperate with the spraying robot 10 to comprehensively spray the track roller 50;

[0028] Both the first rotating element 32 and the second rotating element 362 are implemented as servo motors;

[0029] The plugging mechanism 40 includes a first telescopic element 41, a second telescopic element 42 disposed on both sides of the lifting mechanism 30, and a first lifting cylinder 43 and a second lifting cylinder 44 for respectively driving the first telescopic element 41 and the second telescopic element 42 to move vertically in a fixed direction. Both the first telescopic element 41 and the second telescopic element 42 are implemented as telescopic cylinders. The telescopic ends of the first telescopic element 41 and the second telescopic element 42 are distributed oppositely. At the same time, a magnetic head 411 is connected to the telescopic end of the first telescopic element 41, and an end plate 412 is connected to the magnetic head 411 in a magnetic adsorption manner. In addition, a port plug 413 that matches the port 501 of the idler wheel 50 is connected to the inner end of the end plate 412. A jaw 421 is connected to the telescopic end of the second telescopic element 42, and the jaw 421 cooperates with the port plug 413.

[0030] After clamping the idler wheel 50 before spraying, first rotate the first rotating head 351 and the second rotating head 361 by a predetermined angle to make the ports of the idler wheel 50 located on the front and rear sides respectively. Then, drive the first telescopic element 41 and the second telescopic element 42 to descend in place by the first lifting cylinder 43 and the second lifting cylinder 44 respectively. The first telescopic element 41 drives the end plate 412 and the port plug 413 to insert into the ports 501 at both ends of the idler wheel 50 through the magnetic head 411. Subsequently, the jaw 421 at the end of the second telescopic element 42 clamps and fixes the port plug 413 to overcome the magnetic attraction force. Then, the first telescopic element 41 retracts the magnetic head 411 back to its original position. Then, the jaw 421 of the second telescopic element 42 releases the port plug 413 and retracts back to its original position. The first lifting cylinder 43 and the second lifting cylinder 44 rise and reset to avoid interfering with spraying. After plugging the port 501, full spraying can be started;

[0031] After spraying is completed, the spraying robot 10 resets. The first lifting cylinder 43 and the second lifting cylinder 42 drive the first telescopic element 41 and the second telescopic element 42 to descend in place again. The first telescopic element 41 adsorbs the end plate 412 through the magnetic head 411 and then pulls back to take out the port plug 413 from the port 501 of the idler wheel 50. Finally, the first rotating head 351 and the second rotating head 361 send the idler wheel 50 back to its original position.

[0032] Thus, the idler wheel integrated automatic spraying device provided by the present application clamps and fixes the idler wheel 50 through the first rotating head 351 and the second rotating head 361, drives the idler wheel 50 to rotate under the action of the second rotating element 362, and the spraying robot 10 performs multi-point directional continuous spraying on the idler wheel 50 (such as Figure 5) During this period, the port plugs 413 block the ports 501 at both ends of the idler wheel 50 to avoid affecting the surface quality of the ports 501, so that the integrated fully automated spraying of the idler wheel 50 can be realized, the efficiency of the surface treatment of the idler wheel 50 can be effectively improved, and the spraying quality can be ensured.

[0033] In one embodiment, the lifting mechanism 30 includes a lifting motor 311 and a lifting plate 312. The lifting motor 311 is horizontally installed on the top of the mounting bracket 20 through a mounting plate 313. At the same time, the lifting motor 311 vertically penetrates the mounting plate 313, and a driving gear 314 is coaxially sleeved on the rotating end. The mounting plate 313 is symmetrically provided with lifting sliders 315 on both sides of the rotating end. The lifting sliders 315 extend in the vertical direction. The lifting plate 312 is provided with a lifting groove meshing with the driving gear 314 and a lifting track 316 slidably matched with the lifting sliders 315, so that the lifting plate 312 can be driven to move up and down by the rotation of the driving gear 314. The fixing plate 31 is connected to the bottom of the lifting plate 312.

[0034] In one embodiment, the first telescopic element 41 and the second telescopic element 42 are respectively connected with a guide plate 422. At the same time, a guide shaft 423 is vertically connected to the top of the guide plate 422, and a guide sleeve 21 slidably matched with the guide shaft 423 is installed in the mounting bracket 20. Therefore, the accuracy and stability of the up and down movement of the first telescopic element 41 and the second telescopic element 42 can be further improved through the sliding fit relationship between the guide shaft 423 and the guide sleeve 21, and then the port 501 can be accurately blocked.

[0035] In one embodiment, the integrated automatic spraying device for idler wheels further includes a conveying track 60 for conveying the idler wheels 50. At the same time, an idler wheel support seat 61 is arranged on the conveying track 60 for carrying the idler wheels 50, so that the idler wheels 50 can be automatically conveyed in place in a pipeline form for the first rotating head 351 and the second rotating head 361 to clamp and fix. In addition, a lifting cylinder 62 is installed below the conveying track 60 opposite to the fixing plate 31. At the same time, the telescopic end of the lifting cylinder 62 is vertically connected to the idler wheel support seat 61 for lifting the idler wheel 50 by a certain height and separating it from the conveying track 60. At the same time, the telescopic stroke of the first lifting cylinder 43 and the second lifting cylinder 44 can also be reduced, which is more convenient to use in cooperation with the spraying robot 10 for better spraying.

[0036] In one embodiment, protective covers 63 are symmetrically arranged on both sides of the lifting cylinder 62 at the top of the conveying track 60, and a third telescopic element 64 for driving the two protective covers 63 to move closer to or away from each other is provided, where the third telescopic element 64 can be a cylinder. The protective covers 63 are slidably engaged with both sides of the conveying track 60 through guide rails 65. At the same time, the top plate of the protective cover 63 is higher than the height of the idler wheel support base 61, and is used to protect the idler wheel support base 61 and the conveying track 60 by aligning and pressing the two protective covers 63 tightly during the spraying process, so as to avoid the spraying affecting their support accuracy and conveying accuracy.
