[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figures 1 to 7 As shown, a spraying device for a shock absorber cylinder 100 includes a turntable 1, a cover 2, a spray head 3, a loading and unloading mechanism 4, and a lever mechanism 5. The turntable 1 is rotatably connected to a workbench and has a plurality of circumferentially arranged positioning posts 10 fixed to its upper end. The positioning posts 10 are sleeved with positioning fixtures 11 for fixing the cylinder 10010.

[0027] The positioning fixture 11 includes a sleeve 110, a rubber ring 111, and a rubber plug 113. A circular top plate 112 is fixed to the upper end of the sleeve 110 and can be sleeved on the positioning column 10. The rubber ring 111 is sleeved on the outer circumference of the sleeve 110 and is positioned by means of two upper and lower annular steps 114 provided on the outer circumference of the sleeve 110. The rubber plug 113 is fixed to the upper end of the top plate 112 by means of a connecting column. The outer diameter of the rubber ring 111 is larger than that of the top plate 112. The guide bar 21 can contact the rubber ring 111 and guide the rubber ring 111 to rotate.

[0028] The cover body 2 is installed on the outer periphery of the turntable 1, and one side of the cover body 2 is provided with two notches 20 for loading and unloading respectively. The inner wall of the cover body 2 is also provided with an arc-shaped guide strip 21 for guiding the self-rotation of the positioning tool 11. The spray head 3 is installed at the geometric center of the upper end of the cover body 2 and is used for electrostatic spraying. There are two loading and unloading mechanisms 4 and they are symmetrically arranged at the two ends of the lever mechanism 5. The two loading and unloading mechanisms 4 are used for loading and unloading of the cylinder 100 respectively. One of the loading and unloading mechanisms 4 is also connected to a lifting device 6. The lifting device 6 adopts a jacking cylinder, which is installed on the base on one side of the base 45. The lever 51 in the lever mechanism 5 is also connected to the cleaning mechanism 8 through a horizontal pipe 7 so that the lever 51 can clean the positioning column 10 between the unloading position and the loading position with the help of the cleaning mechanism 8 during repeated rotation;

[0029] The loading and unloading mechanism 4 includes a U-shaped fork 40, a loading and unloading cylinder 41, a second turntable 42, a servo motor 43, a slide 44 and a base 45. The tail of the U-shaped fork is installed on the output end of the loading and unloading cylinder 41, and the loading and unloading cylinder 41 is installed on the second turntable 42. The second turntable 42 is rotatably connected to the slide 44 and the rotating shaft at its lower end is connected to the output end of the servo motor 43. The servo motor 43 is installed at the lower end of the slide 44. The slide 44 is slidably connected to the slide rail provided on the side of the base 45 by means of a slider, and the side of the slide 44 is further provided with a side plate 47 for connecting to the lever mechanism 5. The upper end of one of the slides 44 is also connected to the second top plate 46, and the second top plate 46 is connected to the output end of the lifting device 6;

[0030] The lever mechanism 5 includes a support base 50 and a lever 5. The geometric center of the lever 51 is rotatably connected to a rotating shaft provided on the support base 50. One end of the transverse tube 7 is fixed to the lever 51 and is located on the outer periphery of the rotating shaft. The transverse tube 7 and the rotating shaft are coaxial. The transverse tube 7 passes through the cover body 2 between the two notches 20 and is connected to the cleaning mechanism 8.

[0031] A guide rod 48 is provided on the side plate 47 , and long guide holes 52 are provided at both ends of the lever 51 to match the guide rod 48 .

[0032] The cleaning mechanism 8 includes a connecting block 80 and two fan-shaped plates 81 fixed at both ends of the connecting block 80. Brushes 82 capable of wrapping the positioning column 10 are fixed on opposite sides of the two fan-shaped plates 81. The other end of the horizontal tube 7 is connected to the connecting block 80.

[0033] In this embodiment, the inner opening of the U-shaped fork 40 cooperates with the annular step. When unloading, the U-shaped fork 40 can lift the positioning tool 11 with the help of the annular step 114.

[0034] The specific implementation process of the present invention is as follows:

[0035] The turntable 1 is intermittently rotated by a certain angle under the action of the rotating mechanism, so that the cylinder 10010 is continuously fed in and out of the cover body 2. During the rotation of the turntable 1, the cylinder 10010 can rotate along the positioning column 10 with the help of the rubber ring 111 and the guide bar 21 to improve the uniformity of spraying. When the cylinder 10010 stops, the loading and unloading cylinder 41 for unloading extends and drives the U-shaped fork 40 to be inserted under the annular step 114 below (i.e., locking the positioning tool 11). The output end of the lifting device 6 extends and drives the slide 44 and the U-shaped fork 40 to move upward, and simultaneously drives the positioning tool 11 to move upward. The positioning tool 11 is then separated from the positioning column 10, and the loading and unloading cylinder 41 for unloading is retracted. The cylinder 1 0010 is moved out of the cover body 2. At the same time, with the help of the lever mechanism 5, the positioning tool 11 on which the cylinder 10010 to be sprayed is placed is placed on the positioning column 10 of the loading position under the action of the loading and unloading mechanism 4 for loading; then the output end of the lifting device 6 retracts and drives the loading and unloading mechanism 4 to reset, and the servo motor 43 for unloading rotates a certain angle to transfer the unloaded cylinder 10010 to the side of the turntable 1, and is taken away by the manipulator, while the servo motor 43 for loading rotates a certain angle to the material box, and another set of manipulators places the cylinder 10010 to be sprayed on the U-shaped fork 40 for loading, and then the two loading and unloading cylinders 41 reset and retract, and the servo motor 43 drives the loading and unloading cylinder 41 to rotate to the initial position, ready for the next unloading.

[0036] During the above-mentioned repeated loading and unloading process, the lever 51 also rotates repeatedly, so that the cleaning mechanism 8 can be driven to rotate and swing left and right repeatedly, thereby cleaning the outer periphery and top surface of the positioning column 10 between the unloading position and the loading position, removing the paint attached to its surface, and realizing dead-angle cleaning of the positioning column 10.

[0037] The loading of the cylinder 10010 in the present invention can also be replaced by a robot to improve the spraying efficiency and reduce harm to the human body.

[0038] It is understood from common technical knowledge that the present invention may be implemented by other embodiments that do not depart from its spirit or essential features. Therefore, the embodiments disclosed above are, in all respects, merely illustrative and not exclusive. All modifications within the scope of the present invention or equivalent to the scope of the present invention are intended to be encompassed by the present invention.
