[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The following gives a specific embodiment.

[0025] Please refer to Figure 1 - Figure 5 , the present invention provides a spray-painting device for processing hydraulic cylinders, including a spray-painted bottom plate 1. Above the spray-painted bottom plate 1, a spray-painted pipe 2 is installed. The axis of the spray-painted pipe 2 is parallel to the side of the spray-painted bottom plate 1. One end of the spray-painted pipe 2 is installed with a connection interface 21. Near both ends of the outer wall of the spray-painted pipe 2, L-shaped brackets 22 are fixedly connected. The two L-shaped brackets 22 are respectively slidably installed in the square sleeves at the top of the bottom plate. One end of the top surface of the bottom plate is fixedly connected with a clamping bracket 11. The top of the clamping bracket 11 is installed with a clamping sleeve 12. The inside of the clamping sleeve 12 is sleeved with a rotating shaft rod 3. Both ends of the rotating shaft rod 3 penetrate to the outside of the clamping sleeve 12. One end of the rotating shaft rod 3 is fixedly connected with a rotating bottom plate 31. One side of the rotating bottom plate 31 is installed with a clamping assembly 4. The spray-painted bottom plate 1 installs the rotating shaft rod 3 through the clamping sleeve 12 on the clamping bracket 11. The rotating shaft rod 3 installs the clamping assembly 4 through the rotating bottom plate 31 thereon. The clamping assembly 4 clamps and fixes the rod body of the hydraulic cylinder, realizes the clamping and fixing of the hydraulic cylinder by the device, and can control the overall rotation of the clamped hydraulic cylinder by rotating the rotating shaft rod 3 and the entire clamping assembly 4. The cooperation between the upper sleeve of the spray-painted bottom plate 1 and the L-shaped bracket 22 installs the spray-painted pipe 2. When the connection interface 21 is connected to the paint pipeline, under the pressure provided by the pipeline, the paint is sprayed out from the nozzle of the spray-painted pipe 2. At this time, the rotation of the hydraulic cylinder is coordinated to realize the paint spraying on the outside of its shell;

[0026] AsFigure 3 and Figure 4 As shown in Figure 4 , the clamping assembly 4 includes a bidirectional lead screw 41. An annular groove 411 is formed at the center of the outer wall of the bidirectional lead screw 41. A fixing sleeve 42 is clamped inside the annular groove 411. One end of the fixing sleeve 42 is fixedly connected to the center of the side wall of the rotating bottom plate 31. Extrusion sleeves 43 are externally threaded and installed at both ends of the bidirectional lead screw 41. On one side of the outer walls of the two extrusion sleeves 43, L-shaped connecting rods 431 are symmetrically and fixedly connected. The other ends of the L-shaped connecting rods 431 are fixedly connected to arc-shaped clamping plates 432. On the other side of the outer walls of the two extrusion sleeves 43, limit sliding blocks 433 are fixedly connected. The two limit sliding blocks 433 are respectively slidably installed in the side wall tracks of the rotating bottom plate 31. The bidirectional lead screw 41 is fixed by the cooperation of its annular groove 411 and the fixing sleeve 42, and can rotate following the overall rotation of the rotating bottom plate 31. This enables the oil cylinder to rotate synchronously after being clamped and fixed by the extrusion sleeve 43. When it is necessary to clamp and fix the oil cylinder, rotate the bidirectional lead screw 41 to make the fixing sleeve 42, the extrusion sleeve 43, the L-shaped connecting rod 431 and the arc-shaped clamping plate 432 approach each other, and stop rotating after contacting and extruding the rod body of the oil cylinder. The clamping and fixing of the oil cylinder by the clamping assembly 4, where the fit between the limit sliding block 433 and the side wall track of the rotating bottom plate 31 can prevent the fixing sleeve 42 from rotating synchronously when rotating the bidirectional lead screw 41, increasing the structural rationality of the device;

[0027] As Figure 1 shown in Figure 1 , an auxiliary slide rail 13 is formed at the center of the top surface of the paint spraying bottom plate 1. A slide block base 5 is slidably installed between the inner walls of the auxiliary slide rail 13. A first elastic telescopic rod 51 is installed on the top of the slide block base 5. One end of the first elastic telescopic rod 51 is fixedly connected to a supporting rod 52. The paint spraying bottom plate 1 installs the slide block base 5 through the auxiliary slide rail 13, and the slide block base 5 supports the supporting rod 52 through the first elastic telescopic rod 51. When the oil cylinder to be painted is large in volume and there is an inward concave circular groove at one end, the clamping assembly 4 cannot ensure stable clamping of it. The supporting rod 52 can play a certain supporting role for the inner diameter of the circular groove at one end of the oil cylinder, and this support will not hinder the overall rotation of the oil cylinder, increasing the clamping stability of the clamping assembly 4 for the oil cylinder;

[0028] As Figure 4 and Figure 5As shown in the figure, a screw handle 412 is fixedly connected to one end of the bidirectional lead screw 41. A plurality of limiting circular grooves 413 are formed in the outer periphery of the side wall of the screw handle 412. The plurality of limiting circular grooves 413 are equally angularly opened along the outer peripheral direction of the screw handle 412. A ejector rod 6 is clamped between the inner walls of the limiting circular grooves 413. One end of the ejector rod 6 is fixedly connected to a second elastic telescopic rod 61. One end of the elastic telescopic rod is fixedly connected to one end of the rotating bottom plate 31. Before rotating the bidirectional lead screw 41 as a whole by rotating the screw handle 412, it is necessary to pull the second elastic telescopic rod 61 to separate the ejector rod 6 from the limiting circular groove 413, and make the ejector rod 6 recover after rotation. At this time, the bidirectional lead screw 41 will not rotate, ensuring the clamping stability of the clamping assembly 4 for the oil cylinder. The rotating shaft rod 3 and the clamping assembly 4 are rotated as a whole by operating the rotating handle 32;

[0029] Working principle: The spray paint bottom plate 1 installs the rotating shaft rod 3 through the clamping sleeve 12 on the clamping bracket 11. The rotating shaft rod 3 installs the clamping assembly 4 through the rotating bottom plate 31 thereon. The clamping assembly 4 clamps and fixes the rod body of the oil cylinder, realizing the clamping and fixing of the device for the oil cylinder, and can control the overall rotation of the clamped oil cylinder by rotating the rotating shaft rod 3 and the clamping assembly 4 as a whole. The spray paint pipe 2 is installed above the spray paint bottom plate 1 in cooperation with the L-shaped bracket 22. When the connection interface 21 is connected to the paint pipeline, the paint is sprayed out from the nozzle of the spray paint pipe 2 under the pressure provided by the pipeline. At this time, the rotation of the oil cylinder is coordinated to realize the paint spraying outside its shell. The bidirectional lead screw 41 is fixed by the bidirectional lead screw 41 through the cooperation of the annular groove 411 and the fixed sleeve 42 thereon, and can rotate following the overall rotation of the rotating bottom plate 31. This enables the oil cylinder to rotate synchronously after being clamped and fixed by the extrusion sleeve 43. When it is necessary to clamp and fix the oil cylinder, rotate the bidirectional lead screw 41 to make the fixed sleeve 42, the extrusion sleeve 43, the L-shaped connecting rod 431 and the arc-shaped clamping plate 432 thereon approach each other, and stop rotating after contacting and squeezing the rod body of the oil cylinder. The clamping assembly 4 clamps and fixes the oil cylinder. Among them, the limiting slider 433 fits with the track on the side wall of the rotating bottom plate 31 to prevent the fixed sleeve 42 from rotating synchronously when rotating the bidirectional lead screw 41. The spray paint bottom plate 1 installs the slider base 5 through the auxiliary slide rail 13. The slider base 5 supports the supporting rod 52 through the first elastic telescopic rod 51. When the oil cylinder to be spray painted is large in volume and there is an inner concave circular groove at one end, the clamping assembly 4 cannot ensure stable clamping of it. The supporting rod 52 can play a certain supporting role for the inner diameter of the circular groove at one end of the oil cylinder. Before rotating the bidirectional lead screw 41 as a whole by rotating the screw handle 412, it is necessary to pull the second elastic telescopic rod 61 to separate the ejector rod 6 from the limiting circular groove 413, and make the ejector rod 6 recover after rotation. At this time, the bidirectional lead screw 41 will not rotate. The rotating shaft rod 3 and the clamping assembly 4 are rotated as a whole by swinging the rotating handle 32.
