[0075] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application will be further described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0076]

Embodiment One

[0077] To address the shortcomings of existing technologies, such as Figure 1 , 2 As shown, this invention provides a painting and drying device for automotive parts. The interior of both the painting chamber 1 and the drying chamber 2 has several nozzles arranged in an array based on the conveying path of the conveying mechanism 3, each used for painting and drying respectively. The conveying mechanism 3 is a conveyor belt, wherein, to achieve closed-loop conveying, a method such as... Figure 3 The chain conveyor belt shown.

[0078] It should be noted that tooling 4 is selected for workpieces of different structural dimensions. The workpieces are installed and fixed in tooling 4. During the spraying or drying process of the parts, the workpieces are transported to the spray booth 1 and the drying chamber 2 through the conveying mechanism 3 connected to tooling 4 and pass through in sequence. First, the spray booth 1 is sprayed with paint evenly, and then the workpieces enter the drying chamber 2 from the spray booth 1 to achieve drying.

[0079] During this process, after the tooling 4 enters the spray booth 1 or the drying booth 2, when the moving tooling 4 engages with the stationary meshing drive 6, the tooling 4 and the meshing drive 6 interact, causing the tooling 4 to rotate at a uniform speed, so as to achieve the effect of uniform spraying or drying.

[0080] Specifically, such as Figure 3 As shown, a tooling 4 for an automotive parts spraying and drying treatment device is provided. Each of the two tooling 4s is provided with a connecting frame 41-1 between it and the base frame 42. The two tooling 4s are rotatably connected to the corresponding connecting frame 41-1, and the ends of the two connecting frames 41-1 away from the tooling 4 are slidably connected to the base frame 42. A support frame 41-3 is provided between the two connecting frames 41-1. One end of the support frame 41-3 is connected to one of the connecting frames 41-1, and the other end is rotatably connected to the other connecting frame 41-1.

[0081] The load-bearing component 41a is fixedly connected to one of the upper connecting frames 41-1, which can be welded or integrally formed; the lower connecting frame 41-1 is equipped with a fastener 41-2 for fastening to the base frame 42; the connecting section between the connecting frame 41-1 and the base frame 42 is provided with a limiting section 41-4 that matches the structure of the base frame 42; the base frame 42 has an overall L-shaped structure when viewed from the side; the tooling 4 includes a mounting plate 4-1 and a gear plate 4-2, the gear plate 4-2 is rotatably connected to the connecting frame 41-1, and the gear plate 4-2 is fixedly connected to the mounting plate 4-1, wherein the workpiece to be processed is fixed to the mounting plate 4-1.

[0082] It should be noted that the present invention is an automotive parts spraying and drying treatment device. With the tooling 4 provided, if the structural size of the workpiece to be processed is small, it is suitable for one of the tooling 4 located above, and the workpiece to be processed is installed on this tooling 4.

[0083] If the structure size of the workpiece to be processed is large, such as an automobile hub, the lower tool 4 is more suitable, and the tool 4 needs to be moved to the position of the upper tool 4, so that the larger tool 4 can be normally engaged with the engaging driving member 6 during subsequent conveying:

[0084] During the adjustment of the position of the lower tool 4, the tool 4 is first detached from the fastening of the base frame 42, and then the tool 4 is moved based on the base frame 42. During the movement, the lower tool 4 is vertically moved upward based on the corresponding base frame 42. When the force receiving member one 41a on the tool 4 moves to the position of the upper tool 4 and contacts the guide member two 421 opposite to it, the upper tool 4 is just moved to the position of the open slot one 422, and the force receiving member one 41a on the upper tool 4 rotates based on the direction of the guide member two 421 relative to the open slot one 422 during the continuous upward movement. When the force receiving member one 41a is completely aligned with the guide member two 421, the upper tool 4 is just detached from the blockage of the lower tool 4 in the top view state, so that the subsequent workpiece can be normally installed on the lower tool 4.

[0085] Then, the lower tool 4 is fastened with the base frame 42. In this state, the tool 4 is moved by the conveying mechanism 3, and the engaging driving member 6 in the paint spraying chamber 1 or the drying chamber 2 is rotated at a constant speed, so as to realize uniform spraying of the workpiece.

[0086] As can be understood by those skilled in the art, the key to realizing uniform spraying or drying of the workpiece is to move the tool 4 at a constant speed by the conveying mechanism 3 and to be affected by the engaging driving member 6. In order to accurately control the rotation speed of the tool 4, it is necessary to control the conveying speed of the conveying mechanism 3 to be balanced enough.

[0087] It is worth mentioning that by arranging two tools 4 suitable for workpieces with different structure sizes on the same conveying mechanism 3, the processable range of the paint spraying chamber 1 and the drying chamber 2 is wider;

[0088] And, with the engagement driving piece 6 engaged with the tooling 4, when the conveying mechanism 3 drives the tooling 4 to move relative to the engagement driving piece 6, the tooling 4 is forced to rotate by the engagement driving piece 6, thereby driving the workpiece to rotate at a uniform speed relative to the spray head in the paint spraying chamber 1 or the drying chamber 2, achieving uniform spraying or drying of the automobile parts, effectively solving the problems of white spots caused by excessive spraying, loss of gloss caused by insufficient spraying, and uneven coating thickness caused by uneven drying, while compared with the existing rotating spraying equipment, on the one hand, the structure is simple, the erection cost is low, and the maintainability is stronger, on the other hand, without the need for too many complex program controls, it is more friendly to the operators.

[0089] In addition, based on the base frame 42, the two toolings 4 are matched and lifted, and the guide piece two 421 and the force receiving piece one 41a change the structure state of the two toolings 4. When the tooling 4 located below is used, the tooling 4 located above will not affect the normal use of the tooling 4 below, while ensuring that at least two toolings 4 are erected and put into normal use, the floor space of the device is used reasonably to the greatest extent.

[0090] Further, as shown in Figure 5 The force receiving piece one 41a and the guide piece two 421 are matched in structure, and the guide protrusion 411 is provided on one side of the top end of the force receiving piece one 41a. The guide protrusion 411 is a steel ball, which is embedded in the force receiving piece one 41a and can rotate with the force receiving piece one 41a, so as to minimize the friction between the force receiving piece one 41a and the guide piece two 421 during engagement.

[0091] It should be noted that the present application is a kind of automobile parts spraying drying treatment device, by setting the force receiving piece one 41a and the guide piece two 421, because the spiral groove one 4211 is 0.25 turns, corresponding to the whole circle 360 ° is 90 °, the force receiving piece one 41a is engaged in the guide piece two 421 by the guide protrusion 411 and based on the spiral groove one 4211, when the guide piece two 421 and the force receiving piece one 41a are completely connected, at this time, the tooling 4 attached thereto should be rotated by 90 ° based on the base frame 42.

[0092] As a preferred embodiment, a plurality of toolings 4 located below are fixedly connected to each other, and an external telescopic driving piece is used for synchronous lifting control. The telescopic driving piece is a hydraulic cylinder, and the lifting of the tooling 4 is precisely controlled by an external oil supply system.

[0093] In summary, the working principle of this invention is as follows: During the spraying and drying process of automotive parts, tooling 4 is selected for parts of different structural dimensions. If the part of the part is small, it is directly fixed on the upper tooling 4. If the part of the part is large, it is fixed on the lower tooling 4. At this time, tooling 4 needs to be moved upward so that the lower tooling 4 reaches the position of the upper tooling 4. Then, the position of tooling 4 is fixed. After the position of tooling 4 is fixed, the conveying mechanism 3 is started. Tooling 4 is sent into the paint spraying chamber 1 and the drying chamber 2 by the conveying mechanism 3 to carry out the spraying and drying process in sequence, thereby realizing the processing of automotive parts.

[0094]

Example 2

[0095] Based on the above embodiments, in order to accurately control the rotation speed of the tooling 4, since the structural dimensions of the parts to be processed are not entirely the same, even if they are small-sized parts but have different structural dimensions, the spraying or drying efficiency brought about by the tooling 4, which is installed on the same size, will also be different. In order to make the rotation speed of the parts to be processed relative to the nozzle located inside the spray booth 1 and the drying booth 2 appropriate, this embodiment is proposed to further improve the structure of the meshing drive component 6:

[0096] Specifically, for example Figure 9 As shown, a meshing drive 6 for an automotive parts spraying and drying treatment device has a motor 62 on which the rotor is fixedly connected to a sprocket 621.

[0097] It should be noted that the present invention is an automotive parts spraying and drying treatment device. Through the set meshing drive 6, during the spraying or drying process of the workpiece to be processed, when the tooling 4 moves to mesh with the transmission chain 61, the motor 62 can be started to drive the adjusting frame 622 to rotate at a certain speed through the sprocket 621, so that the rotation speed of the tooling 4 driving the workpiece to be processed is more suitable.

[0098] Among them, motor 62 is a servo motor, and cascaded reducer drives sprocket 621. Based on the programmability of servo motor, the rotation speed of sprocket 621 can be controlled, so that transmission chain 61 drives tooling 4 to transmit at different speeds.

[0099] In a preferred embodiment, the adjusting frame 622 is slidably connected to the frame of the motor 62, and a bolt assembly is provided therebetween for fastening; when the adjusting frame 622 extends, the transmission chain 61 is pulled, and the state of the transmission chain 61 is guided and changed by the adjusting frame 622, such as... Figure 10 The structure shown makes the transmission chain 61 inclined relative to the mating surface of the tooling 4, which allows the tooling 4 to mesh more smoothly with the transmission chain 61.

[0100] Example Three

[0101] Based on the above examples, such as the hub to be processed, in order to ensure the corrosion resistance of the hub, the inner side and the outer side should be sprayed with paint, therefore, the spraying process of the hub is more special than the above examples, in order to facilitate the spraying process of the hub such as the workpiece to be processed, the embodiment is proposed:

[0102] Specifically, as shown in Figure 7 , 8 A work tool 4 for an automobile part spraying and drying treatment device and a guide piece one 5, the guide piece one 5 is located above the whole, and the guide piece one 5 is made of a pipe; the stress piece two 41b attached to the base frame 42 is erected on the upper end of the vertical section; the guide piece one 5 is fixed on the outside, which can be the spraying chamber 1 or the drying chamber 2;

[0103] The straight groove 53 is opened on the inner wall of the guide piece one 5; the two sections of the spiral groove two 52 are symmetrically opened, one section is used to guide the stress piece two 41b to overturn, and the other section is used to guide the stress piece two 41b to reset; the open groove two 51 is relative to the spiral groove two 52; the limiting groove 5-1 for maintaining the stable sliding of the stress piece two 41b is opened below the guide piece one 5.

[0104] Further, the overturning piece 43 in the work tool 4 for the automobile part spraying and drying treatment device, the lower end of the sliding seat 431 is fixedly installed on the conveying mechanism 3, the sliding frame 432 is fixedly connected to the lower end of the base frame 42 or is directly opened therefrom, and the sliding frame 432 is slidingly connected with the sliding seat 431; the sliding seat 431 is a 1 / 4 ring, and the number of turns of the spiral groove two 52 is 0.25, so that the overturning angle of the work tool 4 is exactly 90°.

[0105] It should be noted that the present application is an automobile part spraying and drying treatment device, by setting the work tool 4 and the guide piece one 5, the conveying mechanism 3 is continuously driving the work tool 4 to move, after the outer side of the hub such as the workpiece to be processed is sprayed or dried, the conveying mechanism 3 drives the work tool 4 to move to the spiral groove two 52 on the guide piece one 5 based on the stress piece two 41b, and the work tool 4 is guided and moved based on the spiral groove two 52 through the guide protrusion 411 opened on the stress piece two 41b, and the work tool 4 is overturned based on the sliding frame 432 through the sliding seat 431;

[0106] In this state, the inner side of the overturned hub such as the workpiece to be processed is relative to the spray head inside the spraying chamber 1 or the drying chamber 2, so as to realize the processing and treatment of the inner side.

[0107] As a preferred embodiment, as shown in Figure 6Further, the turnover part 43 in the tool 4 for spraying and drying automobile parts is shown. The flow groove 4311 is arranged in the bottom of the sliding seat 431. Figure 6 In the shown structure, the liquid is quickly drained from the inside of the sliding seat 431, which can effectively avoid the accumulation of liquid between the sliding seat 431 and the sliding carriage 432 during spraying, causing poor sliding.

[0108] In this embodiment, those skilled in the art can understand that in order to better spray the inside of the hub and other workpieces, the spray head should be able to extend into the inside of the hub and other workpieces and be opposite to them. The required structure of the spray head is at most a bent spray head or a telescopic spray head, which is obviously better than the complicated structure process of rotating and moving the spray head in terms of maintainability and structural complexity.

[0109] The above shows and describes the basic principles and main features of the present application and the advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
