Description

Technical Field

With the technological upgrading and capacity expansion of the automobile industry, the production scale of brake discs continues to expand. Production efficiency and product quality have become key factors for companies to gain a foothold in the fierce market competition. At present, the main method of painting brake discs in the industry is manual spraying, which is less efficient and contains a large amount of chemicals such as benzene, toluene, and xylene during the spraying process, which causes great harm to the health of construction workers.

[0003] The Chinese patent with patent announcement number CN215507408U discloses a protective spraying device for automobile parts processing. After the brake disc is clamped by two relatively arranged arc blocks, the brake disc is turned over by meshing the driving gear 1 with the driving gear 2, so that both sides of the brake disc can be evenly sprayed.

This process can only spray a single brake disc, the spraying efficiency is low, and the operation is cumbersome. Secondly, when the brake disc is placed in the box for processing, stains may remain on its surface, resulting in poor subsequent spraying effect or even bubbles, increasing the rework rate and affecting the spraying efficiency of the brake disc.

The spray box 12 is respectively penetrated with an inlet 18 and an outlet 22 which are interconnected at the front and rear. The spray box 12 is penetrated with a moving groove 19 for the clamping mechanism 5 to move. The spray box 12 is divided into a first chamber 34 and a second chamber 39 by a partition 25. The partition 25 is penetrated with a through opening 29. A grinding component is fixedly connected to the first chamber 34 relative to the inlet 18. The spray box 12 is provided with a dust collector 17 whose dust suction port is connected to the first chamber 34. A plurality of spray mechanisms 9 are relatively arranged in the second chamber 39 along the through opening 29. The slide rail 2 is sequentially connected with the first cleaning groove 10, the second cleaning groove 15 and the spray box 12 with a first sinking section 35, a second sinking section 36 and a third sinking section 37.

[0022] Specifically, in the present embodiment, the slide rail 2 and the chain conveyor mechanism 3 are both annular structures, and the operation and specific structures of the two are prior arts. The slide rail 2 and the chain conveyor mechanism 3 are both fixedly mounted on the processing table 1, and the fixing rod 4 is slidably arranged on the slide rail 2 through the sliding rod 31; at the same time, the first cleaning tank 10 can be filled with a cleaning agent or a degreasing agent to facilitate cleaning of the oil stains on the brake disc, and a transition groove 26 is provided on the cleaning cylinder 8 between the first cleaning tank 10 and the second cleaning tank 15 for collecting the liquid dropped from the brake disc, and the water inlet end of the conveying pipe 11 is connected to the external water supply equipment, and is sprayed to the brake disc passing through the second cleaning tank 15 through the shower head 16; the brake disc is fixed by the clamping mechanism 5, and the chain conveyor mechanism 3 is fixed by the clamping mechanism 5. When the conveying mechanism 3 is in operation, the sliding sleeve 30 fixedly connected thereto is driven to move. Since the sliding sleeve 30 is sleeved on the fixed rod 4, and the first end of the fixed rod 4 is slidably arranged on the slide rail 2, the fixed rod 4 will slide on the slide rail 2 as the chain conveying mechanism 3 runs, thereby making the clamping mechanism 5 at the second end of the fixed rod 4 move along the slide rail 2. When the fixed rod 4 moves to the first sinking section 35, the height of the fixed rod 4 and the clamping mechanism 5 slowly decreases, so that the brake disc on the clamping mechanism 5 moves to the first cleaning groove 10 for preliminary cleaning. After cleaning, the fixed rod 4 slowly rises to the initial height along the slide rail 2. At this time, the cleaning agent remaining on the brake disc falls into the collecting groove 14. As the chain conveying mechanism 3 continues to move, the fixed rod 4 The fixed rod 4 comes to the second sinking section 36, at which time the height of the fixed rod 4 and the clamping mechanism 5 slowly decreases, so that the brake disc enters the second cleaning tank 15, and the external water supply equipment delivers water to the delivery pipe 11, and the delivery pipe 11 delivers water to the shower 16, and the shower 16 sprays water on the brake disc to rinse off the residual detergent. As the chain conveying mechanism 3 continues to move, the height of the brake disc rises to the initial height, and then the brake disc is air-dried by the air-drying component 7. As the chain conveying mechanism 3 continues to move, the brake disc moves to the third sinking section 37, so that the brake disc enters the interior of the spray box 12 along the entrance 18, passes through the first chamber 34 and the second chamber 39 in turn, and enters the first chamber 34 through the grinding component. The grinding process is carried out, and the waste chips generated by the grinding are collected by the vacuum cleaner 17, and then reach the second chamber 39 through the through hole on the partition 25 and are sprayed by the spraying mechanism 9. The setting of the movable groove 19 facilitates the movement of the clamping mechanism 5. The movable groove 19 is connected with the inlet 18 and the outlet 22, and the sprayed brake disc is moved out along the outlet 22. The overall structure is simple and the degree of automation is high. Through the cooperation of the chain conveying mechanism 3 and the slide rail 2, the brake disc is automatically transferred between multiple processes such as cleaning, air drying and spraying, thereby improving the production efficiency. The surface of the brake disc is ground by the grinding component to improve the adhesion of the spraying, so that the spraying effect is better, the generation of bubbles during spraying is reduced, and the rework rate is reduced.

[0023] It should be noted that, in this embodiment, the vacuum cleaner 17 is installed between the grinding assembly and the partition 25, and the installation method and working principle of the vacuum cleaner 17 are prior art; secondly, the clamping mechanism 5 is a mechanism that can fix the brake disc, and the multiple sinking sections of the slide rail 2 can be designed with a suitable sinking depth according to actual needs to meet the requirements of different processing procedures.

[0024] In this embodiment, if Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the clamping mechanism 5 includes a fixedly connected rotating rod 51 and a clamping fixture 52. The rotating rod 51 is rotatably set on the fixed rod 4. The clamping fixture 52 is used to fix the brake disc. The fixed rod 4 is provided with a rotating component 6 for driving the rotating rod 51 to rotate. Specifically, the brake disc is fixed by the clamping fixture 52, and the rotating component 6 drives the rotating rod 51 to rotate, thereby driving the brake disc on the clamping fixture 52 to rotate. The rotation of the brake disc can make the cleaning fluid, grinding and spraying materials act more evenly on the surface of the brake disc, thereby improving the quality of cleaning, grinding and spraying. It should be noted that the clamping fixture 52 is a structure that can realize the fixation of the brake disc, for example, the fixation of the brake disc is achieved by two clamping plates and positioning bolts, and can also be achieved by other compatible structures, which are not limited here.

[0025] In this embodiment, if Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig. 9As shown, a rack 20 cooperating with the rotating assembly 6 is fixedly connected to the spray box 12 adjacent to the moving groove 19, and the rack 20 is arranged along the extending direction of the moving groove 19. The rotating assembly 6 includes a fixed box 67, which is fixedly installed on the fixed rod 4. The rotating rod 51 passes through and is rotatably arranged on the fixed box 67. A worm gear 61 is sleeved on the rotating rod 51. A worm 62 meshing with the worm gear 61 is rotatably connected in the fixed box 67. The worm 62 is sleeved with a first bevel gear 63. A rotating shaft 65 passes through and is rotatably arranged on the fixed box 67. A first end of the rotating shaft 65 is sleeved with a second bevel gear 64 meshing with the first bevel gear 63. A second end of the rotating shaft 65 is sleeved with a driving gear 66 meshing with the rack 20. The diameter of the first bevel gear 63 is smaller than that of the second bevel gear 63. The diameter of the gear 64, specifically, when the clamping mechanism 5 moves along the moving groove 19 of the spray box 12, the driving gear 66 meshes with the rack 20, and the driving gear 66 rotates to drive the rotating shaft 65 to rotate, and the second bevel gear 64 on the rotating shaft 65 drives the first bevel gear 63 meshing therewith to rotate, and the first bevel gear 63 drives the worm 62 to rotate, and the worm 62 meshes with the worm wheel 61, thereby driving the rotating rod 51 to rotate. Since the diameter of the first bevel gear 63 is smaller than the diameter of the second bevel gear 64, the rotation speed of the brake disc is increased, and the movement of the clamping mechanism 5 is used to drive the brake disc to rotate. No additional power source is required, the structure is simplified, and the cost is reduced. By driving the brake disc to rotate, the grinding and spraying effects of the brake disc are better.

[0026] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the air-drying component 7 includes two support plates 71, which are relatively arranged on the processing table 1, and a plurality of assembly plates 72 are relatively fixedly connected to the front ends of the two support plates 71, and a wiping cloth 73 is fixedly connected to the opposite side of the plurality of assembly plates 72, and a gap 40 for the clamping mechanism 5 to pass through is defined between the assembly plates 72, and at least one group of fans 74 is fixedly installed at the end of the support plates 71. Specifically, when the clamping mechanism 5 clamps the brake disc through the gap 40 between the assembly plates 72 at the front ends of the two support plates 71, the wiping cloth 73 will wipe the moisture on the surface of the brake disc, and then the fan 74 blows air to the brake disc, further accelerating the evaporation of moisture on the surface of the brake disc, achieving the purpose of air drying, and facilitating the subsequent spraying operation of the brake disc; it should be noted that the material of the wiping cloth 73 should be selected from a material that has good water absorption, is soft and not easy to shed, so as to avoid scratching the surface of the brake disc.

[0027] In this embodiment, if Figure 5 , Figure 6 , Figure 7 , Fig.10 and Fig.11As shown, the spraying mechanism 9 includes a mounting block 95, which is fixedly mounted on the inner wall of the spray box 12, a mounting rod 91, which is arranged on the mounting block 95, and both ends of the mounting rod 91 are rotatably connected to a rotating shaft 92, and the rotating shaft 92 is fixedly connected to a spray head 93 arranged toward the brake disc on the clamping fixture 52, and two groups of spray heads 93 on the two rotating shafts 92 are arranged relatively along the brake disc, and an adjusting mechanism 94 for driving the rotating shaft 92 to rotate is provided on the mounting block 95, and the adjusting mechanism 94 includes a motor 943, which is fixedly mounted On the mounting block 95, a driving disk 941 is fixedly connected to the driving shaft of the motor 943, and driving rods 942 are connected to the two ends of the driving disk 941 for relative rotation. Two rotating handles 945 are respectively fixedly connected to the two rotating shafts 92, and the ends of the two driving rods 942 away from the driving disk 941 are respectively movably arranged on the two rotating handles 945 through movable rods 944. The rotating handles 945 are penetrated with movable grooves 946 for the movable rods 944 to move. Specifically, the motor 943 is controlled by an external control device. A protective box for protecting the motor 943 is fixedly installed on the mounting block 95. The two groups of spray heads 93 are arranged relatively up and down along the brake disc on the clamping mechanism. The driving disc 941 is driven to rotate by the motor 943. The driving rods 942 at both ends of the driving disc 941 move with the rotation of the driving disc 941. The driving rod 942 is connected to the rotating handle 945 through the movable rod 944. The movable rod 944 moves in the movable groove 946 of the rotating handle 945, thereby driving the rotating handle 945 to rotate. The rotating handle 945 is fixed on the rotating shaft. 92, and then drives the rotating shaft 92 to rotate, so as to realize the precise control of the rotation angle and speed of the spray head 93. The rotation of the spray head 93 can make the spraying range wider, cover all parts of the brake disc, and improve the uniformity and integrity of the spraying. It should be noted that, in this embodiment, the spray head 93 is connected to the pump body for externally conveying the special spraying liquid for the brake disc, and the connection method and installation method between the two are prior arts, and the public document with patent announcement number CN115193630B can also be referred to.

[0028] In this embodiment, if Fig.10 and Fig.11 As shown, the mounting rod 91 is movably arranged on the mounting block 95, and an adjusting bolt 33 is threadedly connected to the mounting rod 91. An adjusting groove 32 for the adjusting bolt 33 to move is penetrated along the length direction of the mounting block 95, so that the adjusting bolt 33 passes through the adjusting groove 32 to fix the mounting rod 91 on the mounting block 95. Specifically, by adjusting the position of the mounting rod 91, the distance and angle between the spray head 93 and the brake disc can be changed to meet the spraying requirements of brake discs of different sizes and shapes.

[0029] In this embodiment, if Figure 5 , Figure 6 and Figure 7As shown, there are two partitions 25, which are relatively fixedly connected between the first chamber 34 and the second chamber 39. A transition groove 26 is defined between the two partitions 25, and sponge blocks 21 are relatively fixedly connected to the through port 29, the inlet port 18 and the outlet port 22. Specifically, the transition groove 26 between the two partitions 25 plays a role of buffering and isolation, reducing the mutual interference between the first chamber 34 and the second chamber 39. The setting of the transition groove 26 can prevent the debris generated during the grinding process from entering the second chamber 39 and affecting the spraying quality; the sealing effect of the sponge block 21 can prevent dust and spraying material from leaking, thereby ensuring the cleanliness of the processing environment.

[0030] In this embodiment, if Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a discharge hopper 13 connected to the second chamber 39 is fixedly connected at the bottom of the spray box 12, a filter screen 27 is fixedly connected between the discharge hopper 13 and the second chamber 39, and a filter cotton 28 is fixedly connected to the bottom of the filter screen 27. Specifically, excess spray material during the spraying process will fall to the bottom of the spray box 12 and be discharged through the discharge hopper 13. A filter screen 27 and a filter cotton 28 are arranged between the discharge hopper 13 and the second chamber 39 to filter the spray material and remove impurities and particles therein.

[0031] In this embodiment, if Figure 5 , Figure 6 and Figure 7 As shown, the grinding assembly includes a plurality of mounting plates 23 and sandpaper 24. The plurality of mounting plates 23 are relatively fixedly mounted on the inner wall of the spray box 12 along the inlet 18. The sandpaper 24 is fixedly mounted on the mounting plates 23. The sandpaper 24 contacts the surface of the brake disc. A through groove 38 is penetrated on the mounting plates 23 for the clamping mechanism 5 to pass through. Specifically, the brake disc is grinded by the grinding assembly to increase the surface roughness and improve the adhesion of the paint layer. Of course, in order to improve the cleaning of the brake disc after grinding, a fan 74 is installed in the first chamber 34 to blow the dust on the brake disc to the suction port of the vacuum cleaner 17 through the fan 74 to improve the cleaning effect.

[0032] Working principle: The brake disc is fixed by the clamping mechanism 5. When the chain conveyor mechanism 3 is in operation, the sliding sleeve 30 fixedly connected thereto is driven to move. Since the sliding sleeve 30 is sleeved on the fixed rod 4, and the first end of the fixed rod 4 is slidably arranged on the slide rail 2, the fixed rod 4 will slide on the slide rail 2 as the chain conveyor mechanism 3 is running, thereby making the clamping mechanism 5 at the second end of the fixed rod 4 move along the slide rail 2. When the fixed rod 4 moves to the first sinking section 35, the height of the fixed rod 4 and the clamping mechanism 5 slowly decreases, so that the brake disc on the clamping mechanism 5 moves to the first cleaning groove 10 for preliminary cleaning. After the cleaning is completed, the fixed rod 4 slowly rises along the slide rail 2 to the initial The cleaning agent remaining on the brake disc falls into the collecting tank 14. As the chain conveyor 3 continues to move, the fixing rod 4 comes to the second sinking section 36. At this time, the fixing rod 4 and the clamping mechanism 5 slowly drop in height, so that the brake disc enters the second cleaning tank 15. The external water supply equipment delivers water to the delivery pipe 11, and the delivery pipe 11 delivers the water to the shower 16. The shower 16 sprays the water on the brake disc to rinse the residual cleaning agent. As the chain conveyor 3 continues to move, the height of the brake disc rises to the initial height, and then the brake disc is air-dried by the air-drying component 7. As the chain conveyor 3 continues to move, the brake disc moves. To the third sinking section 37, the brake disc enters the interior of the spray box 12 along the entrance 18, passes through the first chamber 34 and the second chamber 39 in sequence, is polished by the polishing assembly in the first chamber 34, and the waste chips generated by the polishing are collected by the vacuum cleaner 17, and then reaches the second chamber 39 through the through hole on the partition 25 for spraying by the spraying mechanism 9. At the same time, when the clamping mechanism 5 moves along the moving groove 19 of the spray box 12, the driving gear 66 is meshed with the rack 20, and the driving gear 66 rotates to drive the rotating shaft 65 to rotate, and the second bevel gear 64 on the rotating shaft 65 drives the first bevel gear 63 meshed with it to rotate, and the first bevel gear 63 drives The worm 62 rotates, and the worm 62 meshes with the worm wheel 61, thereby driving the rotating rod 51 to rotate, and the rotating rod 51 drives the brake disc to rotate. The setting of the movable groove 19 facilitates the movement of the clamping mechanism 5. The movable groove 19 is connected with the inlet 18 and the outlet 22, and the sprayed brake disc moves out along the outlet 22. The overall structure is simple and the degree of automation is high. Through the cooperation of the chain conveying mechanism 3 and the slide rail 2, the brake disc is automatically transferred between multiple processes such as cleaning, air drying and spraying, which improves the production efficiency.
