Description

Technical Field

[0001] The utility model relates to the technical field of piston printing equipment, in particular to an automatic coating replenishing device. Background Art

[0002] Molybdenum disulfide is a solid lubricant. When the surface of parts is coated with molybdenum disulfide, it can reduce friction during the assembly and operation of parts. As a key component of the engine, the piston is used to withstand the gas pressure. The piston reciprocates in the cylinder to make the connecting rod drive the crankshaft to rotate and output power. In order to improve the self-lubrication and wear resistance of the piston, molybdenum disulfide is coated on the two piston skirt surfaces of the piston to meet the development needs of the engine.

[0003] In the prior art, molybdenum disulfide coating can be attached to the piston by screen printing, so that the surface of the piston skirt forms a lubricating coating with a printed pattern.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model provides an automatic paint replenishing device, including a gantry 1, a Y-axis linear module 2 arranged on the gantry 1, a screen printing plate 3 arranged at the output end of the Y-axis linear module 2, a mounting seat 4 arranged on the gantry 1, an XZ-axis adjustment mechanism 5 arranged on the mounting seat 4, and a glue tank 6, the output end of the XZ-axis adjustment mechanism 5 is provided with a first lifting component 7, a nozzle 8 and a second lifting component 9, the output end of the first lifting component 7 is provided with a scraper 71, the output end of the second lifting component 9 is provided with a push plate 91, and the nozzle 8 is located between the scraper 71 and the push plate 91, and the nozzle 8 is connected to the glue tank 6.

[0026] The glue tank 6 pumps molybdenum disulfide paint into the nozzle 8, and the molybdenum disulfide paint is sprayed from the nozzle 8 to between the scraper 71 and the push plate 91, so as to achieve the purpose of replenishing the molybdenum disulfide paint to the screen printing plate 3; the screen printing plate 3 is provided with mesh holes consistent with the printing pattern, and the molybdenum disulfide paint can adhere to the piston through the mesh holes. During printing, the piston is located at the lower surface of the screen printing plate 3, the first lifting assembly 7 drives the scraper 71 to descend, the bottom of the scraper 71 is in close contact with the upper surface of the screen printing plate 3, and the Y-axis linear module 2 drives the screen printing plate 3 to move horizontally, so that the scraper 71 moves relative to the screen printing plate 3, and the molybdenum disulfide coating adheres to the piston through the mesh under the extrusion of the scraper 71; after a single printing is completed, the first lifting assembly 7 drives the scraper 71 to rise and reset, the second lifting assembly 9 drives the push plate 91 to descend, the bottom of the push plate 91 is in close contact with the upper surface of the screen printing plate 3, and the Y-axis linear module 2 drives the screen printing plate 3 to move horizontally in the opposite direction, so that the push plate 91 moves relative to the screen printing plate 3 to push the molybdenum disulfide coating back to the initial position to ensure that there is enough molybdenum disulfide coating for the scraper 71 to scrape; after multiple printing jobs, the glue tank 6 regularly pumps a certain amount of molybdenum disulfide coating into the nozzle 8 again to achieve the purpose of timely replenishing the molybdenum disulfide coating, thereby ensuring the smooth progress of the printing job.

[0027] In this embodiment, the glue tank 6 is a pressure barrel, which is a prior art, and its specific structure and working principle are not described in detail. The molybdenum disulfide paint is loaded into the pressure barrel, and the pressure barrel is connected to an air generating device. By connecting compressed air, the molybdenum disulfide paint in the barrel is pressed out and finally sprayed out by the nozzle 8.

[0028] In a preferred embodiment, the XZ axis adjustment mechanism 5 is used to adjust the installation positions of the scraper 71 and the push plate 91 together. Figure 3 The XZ axis adjustment mechanism 5 comprises an X axis guide rod 51 arranged on the mounting seat 4, a first movable seat 52 slidably connected to the X axis guide rod 51, a Z axis guide rod 53 slidably connected to the first movable seat 52, a second movable seat 54 arranged at the end of the Z axis guide rod 53, and an adjustment nut 55 rotatably connected to the first movable seat 52, a first adjustment screw 56 abutting against the X axis guide rod 51 is threadedly connected to the first movable seat 52, and an adjustment screw 57 meshing with the adjustment nut 55 is arranged on the second movable seat 54. The first movable seat 52 slides along the X axis guide rod 51, and the first adjustment screw 56 is screwed in to fix the position of the first movable seat 52 in the X axis direction; the adjustment nut 55 is rotated, and the adjustment screw 57 meshes with the adjustment nut 55 to drive the second movable seat 54 to move to any position along the Z axis guide rod 53.

[0029] Further, see Figure 3The first lifting assembly 7 includes a driving cylinder 72 disposed on the second movable seat 54, a guide rod 73 slidably connected to the second movable seat 54, a mounting bar 74 disposed at the lower end of the guide rod 73, and a cross bar 75 disposed at the upper end of the guide rod 73. The output end of the driving cylinder 72 is connected to the mounting bar 74, the scraper 71 is detachably disposed on the mounting bar 74, and a second adjusting screw 76 abutting against the second movable seat 54 is threadedly connected to the cross bar 75. The extension rod of the driving cylinder 72 extends or retracts to drive the scraper 71 to move up and down; by screwing in or out the second adjusting screw 76 to control the extension length of the extension rod of the driving cylinder 72, the descending height of the scraper 71 is finely adjusted, so that the bottom of the scraper 71 can act on the upper surface of the screen printing plate 3.

[0030] For further information, see Figure 5 The installation bar 74 is provided with a first fixing plate 741, the first fixing plate 741 is connected to a second fixing plate 742 by screws, a step portion 743 is provided on a side of the second fixing plate 742 close to the first fixing plate 741, and the scraper 71 is located on the step portion 743.

[0031] In the above, the structure of the second lifting assembly 9 is similar to that of the first lifting assembly 7, and specific reference may be made to the first lifting assembly 7. The second lifting assembly 9 drives the push plate 91 to move up and down, and can fine-tune the descending height of the push plate 91 to ensure that the push plate 91 can act on the screen printing plate 3.

[0032] In a preferred embodiment, see Figure 6 The two sides of the push plate 91 are respectively provided with baffles 911 inclined toward the scraper 71. When the push plate 91 pushes the molybdenum disulfide paint back, the two baffles 911 can prevent the molybdenum disulfide paint from flowing outward through the two sides of the push plate 91, so that more molybdenum disulfide paint can be pushed back to the initial position to avoid waste.

[0033] Preferably, the width of the push plate 91 is greater than that of the scraper 71 , and the push plate 91 can push the molybdenum disulfide coating flowing out from both sides of the scraper 71 back to the initial position.

The fixing clamp 23 is a C-shaped structure, and a third adjusting screw 24 is threadedly connected to the fixing clamp 23, and a pressing plate 25 is connected to the lower end of the third adjusting screw 24. The two fixing clamps 23 are respectively used to fix the corresponding two sides of the screen printing plate 3. When the third adjusting screw 24 is screwed in, the pressing plate 25 presses the screen printing plate 3 against the fixing clamp 23 to ensure the stability of the installation of the screen printing plate 3; when the third adjusting screw 24 is screwed out, the pressing plate 25 is away from the screen printing plate 3, which is convenient for installing and disassembling the screen printing plate 3.

[0035] Further, the third movable seat 21 is provided with two brackets 211, one cantilever beam 22 is slidably connected to one bracket 211, and a fourth adjusting screw 212 is rotatably connected to the bracket 211, and the fourth adjusting screw 212 is threadedly connected to the cantilever beam 22. The fourth adjusting screw 212 is rotated to adjust the installation height of the cantilever beam 22.

[0036] Furthermore, a fifth adjusting screw 221 is rotatably connected to the cantilever beam 22, and the fifth adjusting screw 221 is threadedly connected to the fixing clamp 23. The fifth adjusting screw 221 is rotated to adjust the installation position of the fixing clamp 23.

[0037] In the above, the installation position of the screen printing plate 3 can be adjusted through the Y-axis linear module 2, the fourth adjusting screw 212 and the fifth adjusting screw 221, so that the mesh position on the screen printing plate 3 corresponds to the position on the piston where the molybdenum disulfide coating needs to be printed.

[0038] Preferably, see Figure 4 The two ends of the third movable seat 21 are respectively provided with limit blocks 213, and the mounting seat 4 is provided with two sensors 41 corresponding to the positions of the limit blocks 213. The two sensors 41 respectively detect the positions of the corresponding limit blocks 213 to limit the moving range of the screen printing plate 3.
