Description

Technical Field

[0001] This invention belongs to the field of motor processing technology, specifically a motor housing processing device. Background Technology

[0002] To prevent injury from the high-speed operation of internal components, motors are equipped with a motor housing. In addition, many motors are used in harsh environments, such as high dust and humid environments. Therefore, the motor housing needs to be painted during processing to give it insulation and corrosion protection.

[0003] A patent application with publication number CN214289048U discloses a painting device for processing motor housings. The upper end of the turntable has several tensioning blocks, which work together to form a through-hole conical cavity that is wider at the top and narrower at the bottom. A conical rod is fitted inside the conical cavity. The piston rod of the cylinder moves downwards, pushing the conical rod down and causing the tensioning blocks to separate. The tensioning blocks tighten the motor housing fitted on the outside. The multiple tensioning blocks fix the motor housing, preventing deformation caused by excessive local force. A sprayer is installed on the outside of the spray box. The motor drives the turntable to rotate, causing the motor housing on the turntable to rotate. At this time, the paint sprayed from the spray nozzle can evenly paint the motor housing, resulting in a good painting effect.

[0004] In the aforementioned prior art, the distance between the spray nozzle and the surface of the motor housing cannot be adjusted for motor housings of different sizes. If the distance is too large or too small, it can easily lead to uneven spraying. Furthermore, the nozzle cannot be automatically transferred after the motor housing has been sprayed, which affects the subsequent continuous spraying and processing of the motor housing and reduces work efficiency.

[0005] Therefore, the present invention provides an apparatus for processing motor housings. Summary of the Invention

[0031] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0032] Example 1

[0033] like Figure 1-3As shown in the embodiment of the present invention, a motor housing processing device includes a second workbench 2. A rectangular plate 22 is fixedly connected to the upper end of the second workbench 2. A U-shaped frame 21 is fixedly connected to the upper end of the rectangular plate 22. A painting assembly is provided at the lower end of the U-shaped frame 21. The painting assembly includes a paint tank 4 fixedly connected to the upper end of the U-shaped frame 21. A T-shaped tube 41 is rotatably connected to the lower end of the paint tank 4. A round tube 43 is slidably connected inside the lower end of the T-shaped tube 41. A flexible hose 42 is fixedly connected to one side of the T-shaped tube 41. A first rectangular strip 44 is fixedly connected to the lower end of the round tube 43. The first rectangular strip 44 has a hollow internal structure. The circular tube 43 is internally connected to the first rectangular strip 44. The lower end of the first rectangular strip 44 is provided with several nozzles 47. One end of the first rectangular strip 44 is fixedly connected to a first telescopic rod 441. The lower end of the first telescopic rod 441 is slidably connected to the rectangular plate 22. The other end of the first rectangular strip 44 is fixedly connected to a second telescopic rod 45. One end of the second telescopic rod 45 is fixedly connected to a U-shaped slider 451. One end of the hose 42 is fixedly connected to a second rectangular strip 46. The second rectangular strip 46 has a hollow internal structure and is internally connected to the hose 42. One side of the second rectangular strip 46 is provided with several nozzles 47.

[0034] Specifically, when processing the motor housing, it is necessary to paint it. Painting the motor housing effectively prevents corrosion, waterproofing, and dustproofing, thus protecting the motor. When painting the motor housing, the distance between the spray nozzle 47 and the motor housing needs to be adjusted for different sizes. Too large or too small a distance will result in uneven painting. In this invention, the motor housing is placed at the upper center of the rectangular plate 22. Then, the length of the first telescopic rod 441 is adjusted according to the height of the motor housing. The first telescopic rod 441 drives the spray nozzle 47, located at the lower end of the first rectangular bar 44, to adjust its height. Simultaneously, the first rectangular bar 44, through the second telescopic rod 45, drives the U-shaped slider 451 to slide up and down on both sides of the second rectangular bar 46. At the same time, the first rectangular bar 44 drives the round tube 43 to extend and retract at the lower end of the T-shaped tube 41, adjusting the spray nozzle 47 to a suitable distance from the upper surface of the motor housing. Then, the length of the second telescopic rod 45 is adjusted according to the diameter of the motor housing. The rod 45 drives the nozzle 47 on one side of the second rectangular strip 46 to adjust to a suitable distance between it and the side of the motor housing. Then, it drives the upper end of the T-shaped tube 41 to rotate with the paint tank 4, starting the nozzle 47. Paint flows from the paint tank 4 into the T-shaped tube 41, then into the first rectangular strip 44 through the round tube 43, then into the second rectangular strip 46 through the hose 42, and finally sprayed out by the nozzle 47. The T-shaped tube 41 drives the first rectangular strip 44 to rotate through the round tube 43, and the first rectangular strip 44 drives the nozzle 47 to rotate, spraying the upper surface of the motor housing. The first rectangular strip 44 drives the second rectangular strip 46 to rotate along the side of the motor housing through the second telescopic rod 45, and the second rectangular strip 46 drives the nozzle 47 to spray the side of the motor housing. By adjusting the length of the second telescopic rod 45 and the first telescopic rod 441, the distance between the nozzle 47 and the surface of the motor housing can be adjusted according to different sizes of the motor housing, preventing uneven spraying caused by excessive or insufficient distance. This method is suitable for uniform spraying of motor housings of different sizes.

[0035] like Figure 3 As shown, in this embodiment, a gear ring 411 is fixedly connected to the upper end of the T-shaped tube 41, and the gear ring 411 meshes with a gear 412. The upper end of the gear 412 is rotatably connected to the U-shaped frame 21 through a pin, and the lower end of the gear 412 is fixedly connected to the output end of the third motor 413. The third motor 413 is fixedly connected to the U-shaped frame 21 through a motor base.

[0036] Specifically, when the drive T-tube 41 rotates to drive the spray head 47 to spray the motor housing, the third motor 413 is started to drive the gear 412 to rotate. The gear 412 drives the gear ring 411 to rotate. The gear ring 411 drives the T-tube 41 and the lower end of the paint box 4 to rotate, which drives the spray head 47 to rotate at a uniform speed to spray the motor housing, resulting in more uniform spraying.

[0037] like Figure 4As shown, the rectangular plate 22 in this embodiment is provided with a fixing component in the middle. The fixing component includes two first waist-shaped holes 221 in the middle of the rectangular plate 22, and fixing posts 25 are slidably disposed in the first waist-shaped holes 221 respectively.

[0038] Specifically, before spraying the motor housing, the motor housing needs to be placed in the middle of the rectangular plate 22 to prevent displacement from causing uneven spraying. When the motor housing is placed on the upper end of the rectangular plate 22, the two fixing posts 25 are simultaneously driven to slide to both sides of the first oblong hole 221, so that the fixing posts 25 move closer to the inside of the motor housing and abut against the inside of the motor housing to fix the motor housing and prevent the motor housing from shifting during the spraying process. At the same time, the motor housing can be adjusted to the middle of the rectangular plate 22 to ensure the stability of the motor housing and the spraying effect.

[0039] like Figure 4 As shown, in this embodiment, a second circular plate 24 is provided at the lower middle of the rectangular plate 22, and a cylinder 23 is fixedly connected to the lower end of the rectangular plate 22. A third oblong hole 241 is provided at the middle of the second circular plate 24 corresponding to the position of the first oblong hole 221. The fixing post 25 is slidably disposed in the third oblong hole 241. A first rectangular block 251 is fixedly connected to the lower end of the fixing post 25. A first bidirectional lead screw 252 is threadedly connected to the middle of the first rectangular block 251. The two ends of the first bidirectional lead screw 252 are rotatably connected to the second circular plate 24 through connecting blocks. One end of the first bidirectional lead screw 252 is fixedly connected to the output end of a first motor 253. The first motor 253 is slidably disposed on one side of the cylinder 23.

[0040] Specifically, when it is necessary to fix the motor housing, the first motor 253 is started to drive the first bidirectional lead screw 252 to rotate. The first bidirectional lead screw 252 drives the first rectangular blocks 251 on both sides to slide to both sides at the same time. The first rectangular blocks 251 drive the fixing post 25 to slide to both sides in the third oblong hole 241. The fixing post 25 slides to both sides and closely adheres to the inside sides of the motor housing to fix the motor housing.

[0041] like Figure 4 As shown, the surface of the fixing column 25 in this embodiment is fitted with a rubber sleeve.

[0042] Specifically, the rubber sleeve on the outside of the fixing post 25 is made of soft material, which can prevent the fixing post 25 from excessively squeezing the inside sides of the motor housing, and at the same time increase the friction between the fixing post 25 and the inside sides of the motor housing to prevent slippage.

[0043] like Figure 4As shown, in this embodiment, a second waist-shaped hole 231 is provided on one side of the cylinder 23, a first circular plate 232 is fixedly connected to the lower end of the cylinder 23, the second circular plate 24 can slide inside the cylinder 23, a hydraulic rod 242 is fixedly connected to the upper end of the first circular plate 232, the output end of the hydraulic rod 242 is fixedly connected to the second circular plate 24, one end of the first bidirectional lead screw 252 can slide inside the second waist-shaped hole 231, the first motor 253 is fixedly connected to the U-shaped block 254, and the U-shaped block 254 is slidably connected to one side of the cylinder 23.

[0044] Specifically, to facilitate placing the motor housing on the rectangular plate 22, the fixing post 25 needs to be retracted before placing the motor housing. Before fixing the motor housing, the hydraulic rod 242 is in a retracted state, the second circular plate 24 is at the lower end of the cylinder 23, and the fixing post 25 is inside the cylinder 23. After placing the motor housing on the rectangular plate 22, the hydraulic rod 242 is activated to extend upward, causing the second circular plate 24 to slide upward. The second circular plate 24 drives the fixing post 25 to pass through the third oblong hole 241 and the first oblong hole 221. At this time, the fixing post 25 is located inside the lower end of the motor housing. Then, the fixing post 25 is driven to fix the motor housing, which facilitates the placement of the motor housing without affecting the fixation.

[0045] like Figure 5 As shown, in this embodiment, a first rectangular hole 222 is provided on one side of the first waist-shaped hole 221. The inside of the first rectangular hole 222 is fixed to the stop block 224 by a first spring 223. The stop block 224 can slide inside the first waist-shaped hole 221.

[0046] Specifically, when the fixed post 25 slides in the first oblong hole 221, since the first oblong hole 221 is in an open state, the sprayed paint can easily contaminate the parts driving the fixed post 25 at the lower end. A stop block 224 is provided in the first oblong hole 221. One side of the stop block 224 is held against by the first spring 223, so that one side of the stop block 224 is always in close contact with the fixed post 25. When the fixed post 25 slides to both sides, the fixed post 25 pushes the stop block 224 to squeeze the first spring 223 and slide into the first rectangular hole 222, preventing the paint from contaminating the internal parts and extending the service life.

[0047] like Figure 6 As shown, in this embodiment, the upper ends of the rectangular plate 22 are slidably connected to the two sides of the upper end of the rectangular plate 22, and the upper ends of the curved baffles 3 are fixedly connected to the two sides of the upper end of the curved baffles 3. A cylindrical strip 32 is slidably connected to the middle of one side of the fixed block 31, and the two ends of the cylindrical strip 32 are fixedly connected to the U-shaped frame 21. A second bidirectional screw 33 is threadedly connected to the middle of the other side of the fixed block 31. One end of the second bidirectional screw 33 is fixedly connected to the output end of the second motor 34, and the second motor 34 is fixedly connected to the U-shaped frame 21 through the motor seat.

[0048] Specifically, the paint sprayed during the painting process can easily pollute the surrounding environment. After the motor housing is fixed, the second motor 34 is started to drive the second bidirectional lead screw 33 to rotate. The second bidirectional lead screw 33 drives the fixing blocks 31 on both sides to move closer to the center at the same time. The fixing blocks 31 drive the arc-shaped baffles 3 to move closer to the center at the same time until they merge. The two arc-shaped baffles 3 merge to form a cylindrical tube. At this time, the motor housing is located between the two arc-shaped baffles 3. During the painting process, the arc-shaped baffles 3 provide protection to prevent contamination of other parts of the equipment.

[0049] Example 2

[0050] like Figure 7-8 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a rectangular groove 26 is provided in the middle of the rectangular plate 22, a push rod 261 is rotatably connected to the upper end of one side of the rectangular groove 26, a first electric telescopic rod 262 is fixedly connected to the lower end of one side of the rectangular groove 26, an irregular hole 265 is provided on one side of the push rod 261, one side of the irregular hole 265 is fixedly connected to the first irregular strip 27 by a second spring 266, one side of the first irregular strip 27 is an open cavity structure, and a second irregular strip 272 is slidably connected inside the first irregular strip 27. One side of the irregular strip 272 is an open cavity structure. A second electric telescopic rod 271 is fixedly connected to one side inside the first irregular strip 27. The output end of the second electric telescopic rod 271 is fixedly connected to one side inside the second irregular strip 272. The lower end of the push rod 261 is provided with a second rectangular hole 267. A fourth rectangular block 273 is fixedly connected to one side of the lower end of the first irregular strip 27. The output end of the first electric telescopic rod 262 is fixedly connected to the second rectangular block 263. A first workbench 1 is fixedly connected to both sides of the second workbench 2. A conveyor belt 11 is installed on the upper end of the first workbench 1.

[0051] Specifically, after the motor housing is painted, it needs to be transferred elsewhere for drying. Since the motor housing is coated with paint, it cannot be directly removed as this would damage the freshly painted surface. Using this invention, after the motor housing is painted, the first electric telescopic rod 262 is activated to extend, causing the second rectangular block 263 to move to one side along the lower end of the push rod 261. Since the push rod 261 is triangular, its upper end is flush with the rectangular plate 22. As the second rectangular block 263 moves, it pushes the push rod 261 upwards, causing one side of the push rod 261 to rotate with one side of the rectangular groove 26, making the upper end of the push rod 261 higher than the rectangular plate 22. When the second rectangular block 263 moves to the side of the fourth rectangular block 273, it pushes the fourth rectangular block... 273 slides within the second rectangular hole 267. The fourth rectangular block 273 drives the first irregular strip 27 to slide away from the first electric telescopic rod 262. When the first electric telescopic rod 262 is fully extended, the first irregular strip 27 fully extends out of the irregular hole 265. Then, the second electric telescopic rod 271 is activated, driving the second irregular strip 272 to slide away from the second electric telescopic rod 271 until one end of the second irregular strip 272 contacts the inside of the motor housing. This pushes the inside of the motor housing to move the motor housing to the upper end of the conveyor belt 11. The conveyor belt 11 is then activated to transfer the painted motor housing to another location for drying. The transfer does not damage the paint surface and does not affect the painting of the next motor housing, thus improving work efficiency.

[0052] like Figure 1 As shown, in this embodiment, cylindrical rods 5 are respectively provided on both sides of the conveyor belt 11 on one side. The cylindrical rods 5 are rotatably connected to the first worktable 1, and a lever 51 is fixedly connected to the middle of the cylindrical rods 5.

[0053] Specifically, the unpainted motor housing is placed on the conveyor belt 11 located on the upper end of the first workbench 1 on one side. The conveyor belt 11 is started to rotate, which moves the unpainted motor housing closer to the painting assembly. Then, the cylindrical rods 5 on both sides are driven to rotate. The cylindrical rods 5 drive the paddle block 51 to rotate towards the center at the same time, which moves the unpainted motor housing to the upper end of the rectangular plate 22. Then, the painting assembly is driven to paint, without the need for manual feeding.

[0054] Working principle: When processing the motor housing, it is necessary to spray paint the motor housing. Spraying paint on the outside of the motor housing can effectively prevent corrosion, waterproofing, and dustproofing, thus protecting the motor. The unpainted motor housing is placed on the conveyor belt 11 provided on the upper end of the first workbench 1 on one side. The conveyor belt 11 is started to rotate, which moves the unpainted motor housing closer to the painting assembly. Then, the hydraulic rod 242 is started to extend upward, which moves the second circular plate 24 upward. The second circular plate 24 moves the fixing post 25 through the third oblong hole 241 and the first oblong hole 221. At this time, the fixing post 25 is located inside the lower end of the motor housing. Then, the first motor 253 is started to drive the first double-acting screw 252 to rotate. The first double-acting screw 252 moves the first rectangular blocks 251 on both sides to slide to both sides at the same time. The first rectangular blocks 251 move the fixing post 25 to slide to both sides in the third oblong hole 241. The fixing post 25 slides to both sides and is close to the inside of the motor housing, thus fixing the motor housing.

[0055] After the motor housing is fixed, the second motor 34 is started to drive the second bidirectional lead screw 33 to rotate. The second bidirectional lead screw 33 drives the fixing blocks 31 on both sides to move closer to the center at the same time. The fixing blocks 31 drive the arc-shaped baffles 3 to move closer to the center at the same time until they merge. The two arc-shaped baffles 3 merge to form a cylindrical tube. At this time, the motor housing is located between the two arc-shaped baffles 3. During the painting process, the arc-shaped baffles 3 provide protection to prevent contamination of other parts of the equipment.

[0056] For motor housings of different sizes, the distance between the spray nozzle 47 and the motor housing needs to be adjusted. Too large or too small a distance will result in uneven painting. When using this invention, the motor housing is placed at the upper center of the rectangular plate 22. Then, the length of the first telescopic rod 441 is adjusted according to the height of the motor housing. The first telescopic rod 441 drives the spray nozzle 47, located at the lower end of the first rectangular bar 44, to adjust its height. Simultaneously, the first rectangular bar 44, through the second telescopic rod 45, drives the U-shaped slider 451 to slide up and down on both sides of the second rectangular bar 46. At the same time, the first rectangular bar 44 drives the circular tube 43 to extend and retract at the lower end of the T-shaped tube 41, adjusting the spray nozzle 47 to a suitable distance from the upper surface of the motor housing. Then, the length of the second telescopic rod 45 is adjusted according to the diameter of the motor housing. The second telescopic rod 45 drives the spray nozzle 47, located on one side of the second rectangular bar 46, to a suitable distance from the side of the motor housing. The distance is adjusted, and then the upper end of the T-shaped tube 41 rotates with the paint tank 4, starting the spray head 47. Paint flows from the paint tank 4 into the T-shaped tube 41, then into the first rectangular strip 44 through the round tube 43, then into the second rectangular strip 46 through the hose 42, and finally sprayed out by the spray head 47. The T-shaped tube 41 drives the first rectangular strip 44 to rotate through the round tube 43, and the first rectangular strip 44 drives the spray head 47 to rotate, spraying the upper surface of the motor housing. The first rectangular strip 44 drives the second rectangular strip 46 to rotate along the side of the motor housing through the second telescopic rod 45, and the second rectangular strip 46 drives the spray head 47 to spray the side of the motor housing. By adjusting the length of the second telescopic rod 45 and the first telescopic rod 441, the distance between the spray head 47 and the surface of the motor housing can be adjusted according to the different sizes of the motor housing, preventing uneven spraying caused by excessive or insufficient distance. It is suitable for motor housings of different sizes and can be sprayed evenly.

[0057] When the motor housing is painted, the first electric telescopic rod 262 is activated to extend, causing the second rectangular block 263 to move to one side along the lower end of the push rod 261. Since the push rod 261 is triangular, its upper end is flush with the rectangular plate 22. As the second rectangular block 263 moves, it pushes the push rod 261 upward, causing one side of the push rod 261 to rotate with one side of the rectangular groove 26, making the upper end of the push rod 261 higher than the rectangular plate 22. When the second rectangular block 263 moves to the side of the fourth rectangular block 273, it pushes the fourth rectangular block 273 to slide within the second rectangular hole 267. The fourth rectangular block 273 then drives the first irregular strip 27. Slide the first electric telescopic rod 262 away from the first electric telescopic rod 262. When the first electric telescopic rod 262 is fully extended, the first irregular strip 27 fully extends out of the irregular hole 265. Then, start the second electric telescopic rod 271 to drive the second irregular strip 272 to slide away from the second electric telescopic rod 271 until one end of the second irregular strip 272 contacts the inside of the motor housing. Push the inside of the motor housing to move the motor housing to the upper end of the conveyor belt 11. Start the conveyor belt 11 to transfer the painted motor housing to another place for drying. The transfer will not damage the paint surface and will not affect the painting of the next motor housing, thus improving work efficiency.
