Description

Technical Field

[0001] This invention relates to the field of surface painting technology for riveted parts, specifically to a surface painting device for riveted parts processing. Background Technology

[0002] In industrial manufacturing, riveted parts are key connecting components of mechanical equipment and structural members. Painting their surfaces not only improves their appearance but also enhances their corrosion and wear resistance, extending their service life. Therefore, the quality of the paint directly affects product performance and quality. However, traditional riveted part surface painting equipment has significant technical limitations and struggles to meet the demands of modern production. Traditional devices require clamps to firmly hold the riveted parts to prevent displacement. The clamping area will create a blind spot for painting, resulting in incomplete surface fixation and painting of the clamping points, which affects the performance and quality of the riveted parts and cannot meet high process standards. Traditional equipment is often designed specifically for certain types of riveting parts. When switching to different types, large-scale adjustments, modifications, or even replacements of the entire equipment are required. This is complex and time-consuming, and can interrupt production and reduce production quality. Summary of the Invention

[0003] The purpose of this invention is to provide a surface painting apparatus for riveted parts processing, so as to solve the problems mentioned in the background art.

[0005] Preferably, for painting the surface of the riveted parts, the painting structure includes: a support platform, an L-shaped support plate, a cross slide, an electric push rod, a rotator, and a paint spray head. The support platform is used to support the top connecting parts; the L-shaped support plate is located at the center of the left end of the top surface of the support platform; the cross slide is located on the bottom surface of the right end of the top of the L-shaped support plate; the electric push rod is located on the slide of the cross slide; the rotator is located at the output end of the electric push rod; and the paint spray head is located at the output end of the rotator.

[0006] Preferably, in order to drive the several riveted parts within the fixing device to rotate, the rotating structure includes: a paint collection tank, a support plate, a rectangular box, and a brake motor. The paint collection tank is located at the center of the top surface near the support platform. There are two support plates, which are symmetrically arranged at the centers of the left and right sides of the outer wall of the paint collection tank, and the bottom surfaces of the two support plates are connected and fixed to the top surface of the paint collection tank. There are two rectangular boxes, which are symmetrically arranged on the inner top of the two support plates through two first bearings. There are two brake motors, which are located on the outer top of the two support plates, and the output ends of the two brake motors are connected and fixed to the center of one side of the outer wall of the two rectangular boxes.

[0007] Preferably, in order to cooperate with the painting structure and the flipping structure for comprehensive painting of the riveted parts, the fixing device includes: rectangular blocks, chambers, moving slots, drive components, small electric push rods, first slots, and molds. There are two rectangular blocks, symmetrically arranged on opposite faces of the two rectangular boxes. Each of the two rectangular blocks has a chamber. Two symmetrically arranged moving slots are formed on opposite faces of the two rectangular blocks, and the four moving slots extend into the two chambers respectively. There are two sets of drive components, symmetrically arranged on the center of one side of the inner wall of each of the two chambers. There are four small electric push rods, symmetrically arranged at the four moving ends of the two drive components. Each of the four small electric push rods is embedded in one of the four moving slots, and each of the four small electric push rods can move along the inner wall of the four moving slots. There are four first slots, symmetrically sleeved on one end of the fixing tube of each of the four small electric push rods. There are two molds, symmetrically embedded in the four first slots.

[0008] Preferably, the two molds have several equidistant riveting fixing slots on their opposite surfaces, and the two molds have second slots at their left and right ends, with the pushing ends of four small electric push rods embedded in the four second slots respectively.

[0009] Preferably, by aligning the two sides of the new mold with the four first slots respectively, the output ends of the four small electric push rods are controlled to extend and embed into the second slots at both ends of the new mold, thereby completing the limiting and fixing of the new mold, and the riveting fixing groove of the new mold matches the shape of the riveting part to be painted.

[0010] Preferably, in order to drive the two molds to flip, the driving assembly includes: a gear, a flat brake motor, a rack, and connecting blocks. The gear is disposed at the center of one side of the inner wall of the cavity via a second bearing; the flat brake motor is disposed at the center of one side of the outer wall of the cavity, and the output end of the flat brake motor is connected and fixed to the center of one end of the gear; there are two racks, which are staggered at both ends of the outer wall of the flat brake motor, and the two racks mesh with the gear; there are two connecting blocks, which are staggered at one end of the two racks, and one side of the outer wall of the two connecting blocks is symmetrically connected and fixed to two small electric push rods.

[0011] Preferably, the rotation of the flat brake motor can drive the gear to rotate and move the two racks, thereby causing the two small electric push rods to drive one end of the two molds to move closer to or separate from each other through the two connecting blocks.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. Traditional riveted parts surface painting devices often create painting blind spots at the clamping area due to limitations in their fixing and clamping structures, resulting in incomplete and uneven painting and severely affecting the painting quality. This device, however, fundamentally solves this problem through the precise coordination of its flipping structure and fixing device. During the painting process, after the upper half of the riveted part is painted, two flat brake motors drive two molds to close, limiting and fixing the riveted part while maintaining a certain degree of looseness within the fixing groove. Subsequently, the two brake motors drive the closing molds at the same speed... The tool rotates 180 degrees, and the riveted parts are transferred from one mold to another by their own gravity. Then the molds open, and the unpainted lower half of the riveted parts is completely exposed. At the same time, the cross slide, electric push rod and rotator in the painting structure work together to drive the paint head to move in the X, Y and Z axes and rotate itself, so as to fully paint the exposed part of the riveted parts. The whole process has no clamping or fixing blind spots, realizing truly comprehensive and uniform painting without dead angles, significantly improving the painting quality of the riveted parts and meeting the high requirements of the painting process standards. 2. Traditional painting equipment is typically designed for specific types of riveted parts. Changing the type of riveted part requires a large-scale adjustment or replacement of the entire equipment, making the operation complex. This equipment's fixing device uses a replaceable mold design. The two molds are for the same type of riveted part. When painting different types of riveted parts, only the two molds matching the type of riveted part to be painted need to be replaced. Furthermore, the design of four small electric push rods allows for easy disassembly and fixing of the replaced molds. The four first slots and the pushing ends of the four small electric push rods cooperate to ensure that the molds are installed securely and in precise positions. Regardless of the type of riveted part mold used, the overall structure of the fixing device does not need to be modified. Painting operations on different types of riveted parts can be achieved simply by changing the molds. This highly versatile design greatly expands the application range of the equipment and provides a certain degree of flexibility and versatility. Attached Figure Description

[0018] As a preferred option, further, such as Figure 3 and Figure 4 As shown, the flipping structure 2 includes: a paint collection tank 21, support plates 22, rectangular boxes 23, and a brake motor 24. The paint collection tank 21 is located at the center of the top surface near the support platform 11 and is used to collect and store excess paint that flows out after painting the riveted parts. There are two support plates 22, which are symmetrically arranged at the center of the left and right sides of the outer wall of the paint collection tank 21, and the bottom surfaces of the two support plates 22 are connected and fixed to the top surface of the paint collection tank 21. The two support plates 22 are used to support the top connecting parts, and the two support plates 22 have a certain height to leave a certain operating space for the top connecting parts. There are two rectangular boxes 23. Two rectangular boxes 23 are symmetrically arranged on the top inner side of the two support plates 22 via two first bearings, and each of the two rectangular boxes 23 serves to protect the two brake motors 24. There are two brake motors 24, which are respectively arranged on the top outer side of the two support plates 22. The output ends of the two brake motors 24 are respectively connected and fixed to the center of one side of the outer wall of the two rectangular boxes 23. The two brake motors 24 have a certain self-locking capability, which ensures that the rotating end connecting parts do not shift or rotate in the static state, providing double protection for the safety and positional accuracy of the rotating end connecting parts. Moreover, these two brake motors 24 can replace more precise rotating mechanical components.

[0019] As a preferred option, further, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the fixing device 3 includes: rectangular blocks 31, chambers 32, moving slots 33, drive components 34, small electric push rods 35, first slots 36, and molds 37. There are two rectangular blocks 31, symmetrically arranged on opposite sides of two rectangular boxes 23. Each rectangular block 31 has a chamber 32, providing operating space for the two drive components 34. Two through-type symmetrical moving slots 33 are respectively opened on opposite sides of the two rectangular blocks 31, and the four moving slots 33 extend into the two chambers 32. There are two sets of drive components 34, symmetrically arranged on one side of the inner wall of each of the two chambers 32. The two drive components 34 can move the two molds 37 vertically via the four small electric push rods 35. Approaching or separating; there are four small electric push rods 35, symmetrically arranged at the four moving ends of the two drive components 34. The four small electric push rods 35 are embedded in the four moving slots 33, and the four small electric push rods 35 can move along the inner wall of the four moving slots 33. The four small electric push rods 35 have a certain load-bearing and support function for the connecting parts of the pushing end; there are four first slots 36, symmetrically sleeved at one end of the fixing tube of the four small electric push rods 35. The four first slots 36 play a role in limiting the two molds 37; there are two molds 37, symmetrically embedded in the four first slots 36. The opposite surfaces of the two molds 37 are respectively provided with a number of equidistant riveting points. The two molds 37 each have a fixing groove 38 and two second slots 39 at both ends. Four small electric push rods 35 are embedded in the four second slots 39, and each slot matches the push rod. The interaction between the two slots 39 and the push rods 35 provides limiting, fixing, and support for the two molds 37. The two molds 37 are for the same type of riveting part; for different types of riveting parts, only two different types of molds 37 need to be replaced. The four small electric push rods 35 are designed for easy disassembly, replacement, and fixing, providing flexibility and versatility. Regardless of which type of riveting part the two molds 37 are replaced with... Each of the four first slots 36 is present, solely for engaging and fixing with the four small electric push rods 35. Several riveting component fixing slots 38 within the two molds 37 match the model of the riveting component to be fixed. The riveting component has a certain degree of looseness within the riveting component fixing slots 38 and will not shift. Its function is to allow the riveting component in one mold 37 to be transferred to the other mold 37 by its own gravity during the flipping process. By aligning the two sides of the new mold 37 with the four first slots 36 respectively, the output ends of the four small electric push rods 35 are controlled to extend and embed into the second slots 39 at both ends of the new mold 37, thus completing the limiting and fixing of the new mold 37. The riveting component fixing slots 38 of the new mold 37 match the shape of the riveting component to be painted.

[0020] As a preferred option, further, such as Figure 7 , Figure 8 and Figure 9 As shown, the drive assembly 34 includes: a gear 341, a flat brake motor 342, a rack 343, and a connecting block 344. The gear 341 is disposed at the center of one side of the inner wall of the chamber 32 via a second bearing; the flat brake motor 342 is disposed at the center of one side of the outer wall of the chamber 32, and the output end of the flat brake motor 342 is fixedly connected to the center of one end of the gear 341. The flat brake motor 342 occupies a small space, which is suitable for the spatial distribution of this device, and the flat brake motor 342 has a certain self-locking capability; there are two racks 343, which are staggered at both ends of the outer wall of the flat brake motor 342, and the two racks 343 mesh with the gear 341; there are two connecting blocks 344, which are staggered at both ends of the outer wall of the flat brake motor 342. One end of each of the two racks 343 and one side of the outer wall of each of the two connecting blocks 344 are symmetrically connected and fixed to two small electric push rods 35. The rotation of the flat brake motor 342 can drive the gear 341 to rotate and move the two racks 343. Thus, through the two connecting blocks 344, the two small electric push rods 35 drive one end of each mold 37 to move closer or separate from each other. Similarly, the two sets of drive components 34 can drive the molds 37 to move closer or separate from each other. This drive component has a certain degree of synchronization and occupies a small space, which is suitable for the spatial distribution of this device. It also has a certain self-locking ability. Through the mutual cooperation of the two gears 341 and the four racks 343, several riveting parts in the two molds are driven to open and close.

[0021] The detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process. The specific operation is as follows: Compared with the traditional method of painting the surface of riveted parts, there are blind spots in the painting at the fixing and clamping points, which reduces the painting quality of the riveted parts. This invention solves the above problems. The same type of riveted parts are placed in several riveted part fixing slots 38 of the bottom mold 37 with the same direction by a robotic arm. The paint spray head 16 is driven by the cooperation of the cross slide 13, electric push rod 14 and rotator 15 to paint both sides of the surface of the riveted parts. After the upper half of the surface of the riveted parts is painted, two flat brake motors 342 drive two molds 37 to close and limit the riveted parts. At the same time, the riveted parts that are limited and fixed can move slightly in several riveted part fixing slots 38 and remain loose in the riveted part fixing slots 38. Thus, the two brake motors 24 drive the two closed molds at the same speed. Mold 37 rotates 180 degrees, allowing several riveted parts to be transferred from one mold 37 to another by their own gravity. Similarly, two flat brake motors 342 drive the two molds 37 to open, exposing the unpainted half of several riveted parts. The paint spray head 16 is then driven by the cross slide 13, electric push rod 14, and rotator 15 to paint both sides of the unpainted half of the riveted parts. This device can paint the surface of the riveted parts in areas without clamping or fixing blind spots, thereby improving the painting quality of the riveted parts. The two molds 37 are for the same type of riveted parts. When encountering different types of riveted parts, only the mold of the same type needs to be replaced. The four second slots 39 of the two molds 37 are engaged and fixed by the moving ends of four small electric push rods 35. This invention can easily disassemble molds of different types of riveted parts and has a certain degree of versatility.
