Description

Technical Field

[0001] This invention relates to the field of parts manufacturing technology, and more specifically, to a painting device for mechanical parts. Background Technology

[0002] Mechanical parts, also known as mechanical components, are the basic building blocks of machinery. They are inseparable individual parts that make up machines. In the machinery manufacturing industry, surface treatment of mechanical parts is a crucial process that directly affects their corrosion resistance, wear resistance, and aesthetics. Painting, as a common surface treatment method, is widely used in the processing of various mechanical parts.

[0003] Painting is a crucial step in the manufacturing process of mechanical parts. The quality of rust-proof and corrosion-proof coatings is an important aspect of overall product quality. Some mechanical parts require full painting during production. However, most mechanical parts require manual rotation for spraying on both sides, as automatic rotation is not feasible. Furthermore, while spraying the coating liquid onto the surface of the parts using a spray gun, the varying sizes and shapes of the parts often make it difficult to achieve uniform distribution of the coating liquid, resulting in poor painting effects. Summary of the Invention

[0004] To overcome the aforementioned deficiencies of the prior art, this invention provides a painting device for mechanical parts. The paint is filtered through a filter screen and collected in a collection chamber, allowing for paint recycling. A rotating gear causes the mechanical parts to flip automatically, ensuring comprehensive painting without manual turning, thus improving the painting efficiency. The spray nozzle rotates during the painting process, further enhancing the uniformity of the paint application. The more inclined nozzle facilitates painting the sides and angled edges of the mechanical parts, increasing the painting range and avoiding dead zones that could affect the painting effect, thereby solving the problems mentioned in the background art.

A moving motor is fixedly installed on one side of the top rail, and a moving screw is fixedly installed on one side of the moving motor. The moving screw is rotatably installed inside the top rail, and the painting assembly is slidably installed inside the sliding groove.

[0011] In a preferred embodiment, the painting assembly includes a movable frame, with sliding blocks fixedly installed on both sides of the top of the movable frame. The sliding blocks are threaded onto the outer surface of a movable screw and slidably installed inside a top track. A rotary connector is rotatably installed on the top of the movable frame, and a fixed water outlet is rotatably installed on the top of the rotary connector. One side of the fixed water outlet is connected to an inlet pipe. A transmission gear is fixedly sleeved on the lower outer surface of the rotary connector.

[0014] In a preferred embodiment, a fixing plate is fixedly installed on one side of the paint spray nozzle, and movable limiting wheels are rotatably installed on both sides of the fixing plate.

[0015] In a preferred embodiment, the two ends of the limiting frame are arc-shaped.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. When the painting component of this invention is used to spray paint mechanical parts, the paint is intercepted by a protective cover to prevent the paint from splashing. The sprayed paint drips into the trapezoidal groove on the top of the circulation base, so that the paint is filtered through the filter screen and collected in the inside of the collection chamber, so that the sprayed paint can be recycled.

[0018] 2. The present invention has two moving blocks at the top of the electric track and a fixed rack in the middle of the fixed bar. The mechanical parts are clamped by the clamping parts at both ends of the electric track. When the moving blocks move, when they pass the top of the fixed rack, the mechanical parts are flipped by the action of the rotating gear, so that the mechanical parts are automatically flipped and can be fully painted without manual flipping, thus improving the painting efficiency of the painting equipment.

[0019] 3. In the process of painting mechanical parts, the painting assembly of the present invention drives the second counter-rotating screw to rotate by starting the reciprocating motor, so that the moving rods at both ends drive the painting nozzles on both sides to reciprocate at both ends of the rotating frame, thereby expanding the painting range of the painting nozzles. By rotating the moving screw, the painting assembly moves laterally inside the protective cover, so that it can adapt to larger mechanical parts. At the same time, the rotating motor drives the drive gear to rotate, thereby causing the painting nozzles at both ends to rotate and spray during the painting process, thereby improving the uniformity of the paint on the mechanical parts.

[0020] 4. By setting the two ends of the limiting frame to be arc-shaped, when the fixed plate moves to one end of the limiting frame, the moving limiting wheel at one end of the fixed plate is located at the lower end of the limiting frame, and the moving limiting wheel at the other end is located at the upper end of the limiting frame, making the paint spray head more inclined, which facilitates painting the sides and oblique sides of mechanical parts, increases the painting range of mechanical parts, avoids painting dead corners, and avoids affecting the painting effect of mechanical parts.

The sprayed paint drips into the trapezoidal groove on the top of the circulation base 11, so that the paint is filtered through the filter screen 13 and collected into the inside of the collection chamber 14, allowing the sprayed paint to be recycled.

[0034] A painting device for mechanical parts includes a painting machine body 1, with moving devices 2 fixedly installed on both sides of the top of the painting machine body 1, and a protective component 3 fixedly installed on the top of the painting machine body 1.

[0035] The moving device 2 includes an electric track 21, a moving block 22 slidably mounted on the top of the electric track 21, a support frame 23 fixedly mounted on the top of the moving block 22, a rotating shaft rotatably mounted inside the support frame 23, a clamping member 24 fixedly mounted on one side of the rotating shaft, a rotating gear 28 fixedly mounted on the other end of the rotating shaft, a fixing strip 29 fixedly mounted on the top of the electric track 21, a fixing rack 210 fixedly mounted in the middle of the fixing strip 29, and the outer surface of the rotating gear 28 meshing with the top of the fixing rack 210.

[0036] like Figure 3 As shown, the painting machine body 1 includes a circulation base 11, a fixed platform 12 is fixedly installed on the top of the circulation base 11, a trapezoidal groove is opened at the upper end of the circulation base 11, a collection chamber 14 is opened at the lower end inside the circulation base 11, the top of the collection chamber 14 is connected to the trapezoidal groove, a filter screen plate 13 is arranged inside the circulation base 11 above the collection chamber 14, an outlet pipe 15 is fixedly connected to the lower end of the collection chamber 14, and a circulation pump is fixedly connected to one side of the outlet pipe 15.

[0037] The trapezoidal groove on the top of the circulation base 11 facilitates the collection of sprayed paint, which is then filtered through the filter screen 13.

[0038] Second Embodiment

[0039] As attached Figure 1 To be continued Figure 5 In one embodiment of the present invention, since two moving blocks 22 are provided on the top of the electric track 21 and a fixed rack 210 is provided in the middle of the fixed strip 29, the mechanical parts are clamped by the clamping members 24 at both ends of the electric track 21. During the movement of the moving blocks 22, when they pass the top of the fixed rack 210, the mechanical parts are flipped by the action of the rotating gear 28, thereby automatically flipping the mechanical parts so that they can be fully painted without manual flipping, thus improving the painting efficiency of the painting equipment.

[0041] The two ends of the mechanical parts are clamped and fixed by the clamping parts 24 at both ends, and two moving blocks 22 are provided so that the two moving blocks 22 can be moved to the bottom of the painting assembly 4, so that the two painting assemblies 4 can spray the two mechanical parts at the same time.

[0042] Third Embodiment

[0043] As attached Figure 1 To be continued Figure 9 In one embodiment of the present invention, in order to improve the uniformity of painting on mechanical parts, during the painting process of the painting assembly 4, the reciprocating motor 49 is started to drive the second counter-rotating screw 410 to rotate, so that the moving rods 411 at both ends drive the painting nozzles 416 on both sides to reciprocate at both ends of the rotating frame 48, thereby expanding the painting range of the painting nozzles 416. By rotating the moving screw 38, the painting assembly 4 moves laterally inside the protective cover 31, so that it can accommodate larger mechanical parts. At the same time, the rotating motor 46 drives the drive gear 47 to drive the transmission gear 45 to rotate, thereby causing the painting nozzles 416 at both ends to rotate and spray during the painting process, thereby improving the uniformity of painting on the mechanical parts.

[0044] As attached Figure 6 To be continued Figure 7 As shown, the protective component 3 includes a protective cover 31 fixedly installed on the top of the fixed platform 12. Sliding grooves 32 are provided on both sides of the top of the protective cover 31. A support cover 33 is fixedly installed in the middle of the top of the protective cover 31. Movable grooves 34 are provided on both sides of the support cover 33. An inlet pipe 35 is sleeved inside the support cover 33 and is connected to the circulation pump.

[0045] The protective cover 31 has two top rails 36 on both sides of its inner wall. The two top rails 36 are located on both sides of the sliding groove 32. A moving motor 37 is fixedly installed on one side of the top rail 36, and a moving screw 38 is fixedly installed on one side of the moving motor 37. The moving screw 38 is rotatably installed inside the top rail 36, and the painting component 4 is slidably installed inside the sliding groove 32.

[0046] The top track 36 allows the painting component 4 to move laterally during the spraying process, thereby achieving lateral painting of large mechanical parts. In addition, in conjunction with the electric track 21, the longitudinal movement of the mechanical parts is controlled, enabling longitudinal painting of large parts. This allows the device to be adapted to mechanical parts of different sizes, thus improving the adaptability of the painting device.

[0047] like Figures 8 to 9As shown, the painting assembly 4 includes a movable frame 41. Sliding blocks 42 are fixedly installed on both sides of the top of the movable frame 41. The sliding blocks 42 are threaded onto the outer surface of the movable screw 38 and slidably installed inside the top track 36. A rotary connector 44 is rotatably installed on the top of the movable frame 41. A fixed water outlet 43 is rotatably installed on the top of the rotary connector 44. One side of the fixed water outlet 43 is connected to the liquid inlet pipe 35. A transmission gear 45 is fixedly sleeved on the lower outer surface of the rotary connector 44. The transmission gear 45 is rotatably installed on the bottom of the movable frame 41. A rotary motor 46 is fixedly installed on the top of the movable frame 41. A drive gear 47 is fixedly installed on the bottom of the rotary motor 46. The drive gear 47 is rotatably installed on the bottom of the movable frame 41, and the outer surface of the drive gear 47 meshes with the outer surface of the transmission gear 45.

[0048] The bottom of the transmission gear 45 is fixedly mounted with a rotating frame 48, a reciprocating motor 49 is fixedly mounted on one side of the rotating frame 48, a second counter-rotating screw 410 is fixedly mounted on one side of the reciprocating motor 49, the second counter-rotating screw 410 is rotatably mounted inside the rotating frame 48, and a limit frame 415 is fixedly mounted on the bottom of the rotating frame 48.

[0049] Among them, the outer surfaces of the two ends of the second eccentric screw 410 are threaded with moving rods 411, which are slidably installed at both ends of the rotating frame 48. The lower end of the moving rod 411 is provided with a limit groove 412. One end of the bottom of the rotating connector 44 is fixedly installed with a connecting tee 413, and both ends of the connecting tee 413 are fixedly connected to a spray pipe 414. Both ends of the spray pipe 414 are fixedly connected to a paint spray nozzle 416.

[0050] The painting nozzle 416 is fixedly mounted on one side with a fixed plate 417. Movable limit wheels 418 are rotatably mounted on both sides of the fixed plate 417. The movable limit wheels 418 are rotatably mounted inside the limit frame 415. A positioning rod 419 is rotatably mounted in the middle of the fixed plate 417. The positioning rod 419 is slidably mounted inside the limit frame 415. One side of the positioning rod 419 is movably sleeved inside the limit groove 412.

[0051] The two ends of the limiting frame 415 are arc-shaped.

[0052] Since the two ends of the limiting frame 415 are arc-shaped, when the fixing plate 417 moves to one end of the limiting frame 415, the moving limiting wheel 418 at one end of the fixing plate 417 is located at the lower end of the limiting frame 415, and the moving limiting wheel 418 at the other end is located at the upper end of the limiting frame 415, making the paint spray head 416 more inclined, which facilitates painting the sides and oblique sides of the mechanical parts, increases the painting range of the mechanical parts, avoids painting dead corners, and affects the painting effect of the mechanical parts.

[0053] Working principle of the invention: When in use, the electric track 21 works, causing the two moving blocks 22 at the top of the electric track 21 to move to the right side of the fixed platform 12. The clamping motor 25 is started, and the clamping block 27 clamps and fixes the mechanical parts, so that the two mechanical parts are respectively installed inside the two clamping members 24. Then, the electric track 21 drives the two moving blocks 22 to move to the left.

[0054] When the mechanical parts on the moving block 22 on the top left of the electric track 21 reach the bottom of the painting component 4 on the right side of the protective component 3, the mechanical parts are painted by the painting component 4. After the painting is finished, the electric track 21 continues to drive the moving block 22 to move to the left. The first moving block 22 passes the top of the fixed rack 210 in the middle of the fixed bar 29. Through the action of the rotating gear 28, the mechanical parts on the left moving block 22 are flipped and enter the bottom of the painting component 4 on the left side inside the protective component 3. At this time, the right moving block 22 is located below the painting component 4 on the right side of the protective component 3, so that the two painting components 4 paint the two mechanical parts at the same time. After the painting is finished, the electric track 21 continues to drive the moving block 22 to move to the left. At this time, the mechanical parts on the clamping part 24 on the right side of the electric track 21 are flipped and enter the bottom of the painting component 4 on the left side of the protective component 3 for painting. After the painting is finished, they move to the left side of the circulating base 11 for unloading.

[0055] During the painting process, the moving motor 37 operates, causing the moving frame 41 to move laterally inside the protective cover 31, thereby achieving lateral painting of large mechanical parts. In addition, in conjunction with the electric track 21, the longitudinal movement of the mechanical parts is controlled, achieving longitudinal painting of large parts, making the device adaptable to mechanical parts of different sizes. By starting the reciprocating motor 49, the second counter-rotating screw 410 is driven to rotate, causing the moving rods 411 at both ends to drive the painting nozzles 416 on both sides to reciprocate at both ends of the rotating frame 48, expanding the painting range of the painting nozzles 416. At the same time, the rotating motor 46 causes the drive gear 47 to drive the transmission gear. 45 rotates, causing the rotating frame 48 to rotate at the bottom of the moving frame 41, thereby causing the paint spraying nozzles 416 at both ends to rotate and spray during the painting process. In addition, since the two ends of the limiting frame 415 are arc-shaped, when the fixed plate 417 moves to one end of the limiting frame 415, the moving limiting wheel 418 at one end of the fixed plate 417 is located at the lower end of the limiting frame 415, and the moving limiting wheel 418 at the other end is located at the upper end of the limiting frame 415, making the paint spraying nozzle 416 more inclined, which facilitates painting the sides and oblique sides of the mechanical parts, increases the painting range of the mechanical parts, avoids painting dead corners, and affects the painting effect of the mechanical parts.

[0056] When the painting component 4 is spraying paint onto the mechanical parts, the protective cover 31 intercepts the sprayed paint to prevent it from splashing. The sprayed paint drips into the trapezoidal groove on the top of the circulation base 11, so that the paint is filtered through the filter screen 13 and collected into the collection chamber 14, allowing the sprayed paint to be recycled.

[0057] Finally, it should be noted that: the accompanying drawings of the embodiments disclosed in this invention only involve structures related to the embodiments disclosed in this invention; other structures can refer to general designs. In the absence of conflict, the same embodiment and different embodiments of this invention can be combined with each other.

[0058] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
