[0056] In order to make the technical means, creative features, purposes and effects realized by 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 a part of the embodiments of the present application, rather than 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.

[0057]

Embodiment One

[0058] It should be noted that the tooling 4 is selected according to the structure and size of the workpiece to be processed, and the workpiece is fixed on the tooling 4. During the process of spraying or drying the parts, the workpiece is transported to the paint spraying chamber 1 and the drying chamber 2 through the conveying mechanism 3 connected with the tooling 4, and then passes through the paint spraying chamber 1 for uniform spraying, and then enters the drying chamber 2 for drying. During this process, after the tooling 4 enters the paint spraying chamber 1 or the drying chamber 2, when the moving tooling 4 engages with the stationary engaging drive 6, the tooling 4 and the engaging drive 6 interact, causing the tooling 4 to rotate at a uniform speed, thereby achieving uniform spraying or drying.

[0059] Specifically, as shown in Figure 3 A tooling 4 for an automobile part spraying and drying treatment device is provided, two toolings 4 and a base frame 42 are provided with a connecting frame 41-1, the two toolings 4 and the corresponding connecting frames 41-1 are respectively rotationally connected, and the ends of the two connecting frames 41-1 away from the tooling 4 are slidingly connected with the base frame 42, a support frame 41-3 is arranged 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 rotationally connected to the other connecting frame 41-1. The force receiving member 41a is fixedly connected to the upper connecting frame 41-1, which can be welded or integrally formed; the lower connecting frame 41-1 is provided with a fastener 41-2 for fastening connection with the base frame 42; the connecting frame 41-1 and the base frame 42 are provided with a limiting section 41-4 matching the structure of the base frame 42; the base frame 42 has a "L" type structure in overall side view; the tooling 4 comprises a mounting disc 4-1 and a toothed disc 4-2, the toothed disc 4-2 is rotationally connected with the connecting frame 41-1, and the toothed disc 4-2 is fixedly connected with the mounting disc 4-1, and the workpiece is fixed on the mounting disc 4-1.

[0060] It should be noted that the present application is an automobile part spraying and drying treatment device, and the tooling 4 is provided. If the structure and size of the workpiece to be processed are small, the upper tooling 4 is suitable for installing the workpiece on the tooling 4. If the structure and size of the workpiece to be processed are large, such as automobile hubs, the lower tooling 4 is more suitable for moving to the position of the upper tooling 4, so that the larger tooling 4 can normally engage with the engaging drive 6 during subsequent transportation. In the process of adjusting the position of the lower tool 4, the tool 4 is first released from the fastening with the base frame 42, and then the tool 4 is moved upward based on the corresponding base frame 42. When the force receiving member 41a of the tool 4 above the other tool 4 contacts the guide member 421 opposite to it, the tool 4 above is just moved to the position of the open slot 422, and the force receiving member 41a of the tool 4 above is rotated based on the guide member 421 opposite to the direction of the open slot 422 during the continuous upward movement. When the force receiving member 41a is completely aligned with the guide member 421, the tool 4 above is just released from the blocking of the tool 4 below in the top view state, so that the subsequent workpiece can be normally installed on the tool 4 below.

[0061] Then, the tool 4 below is fastened with the base frame 42. In this state, the tool 4 is moved by the conveying mechanism 3 at a constant speed through the meshing driving member 6 in the paint spraying chamber 1 or the drying chamber 2 to realize uniform spraying of the workpiece.

[0062] As 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 act on the meshing 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 uniform.

[0063] It is worth mentioning that by arranging two tools 4 for workpieces with different structural sizes on the same conveying mechanism 3, the processable range of the paint spraying chamber 1 and the drying chamber 2 is wider. Moreover, when the tool 4 is moved relative to the meshing driving member 6 by the conveying mechanism 3, the tool 4 is rotated by the meshing driving member 6 to drive the workpiece to rotate at a constant speed relative to the spray head in the paint spraying chamber 1 or the drying chamber 2, thereby realizing uniform spraying or drying of the automobile parts. This effectively solves the problems of whitening caused by excessive spraying, loss of gloss caused by insufficient spraying, and uneven coating thickness caused by uneven drying and blowing, and is more friendly to the operator because it does not require complex program control. Further, the two toolings 4 are matched and lifted based on the base frame 42, and the guide member two 421 and the force receiving member one 41a change the structure state of the two toolings 4, when the tooling 4 located below is used, the tooling 4 located above does not affect the normal use of the tooling 4 below, and the land occupation of the device is reasonably utilized to the maximum extent while ensuring that at least two toolings 4 are normally used.

[0064] Further, as shown in Figure 5 The force receiving member one 41a and the guide member two 421 are matched in structure, the guide protrusion 411 is arranged on the top end of the force receiving member one 41a, the guide protrusion 411 is a steel ball, and is rotatably arranged in the force receiving member one 41a, so that the friction between the force receiving member one 41a and the guide member two 421 during engagement is minimized.

[0065] It should be noted that the present application is a kind of automobile parts spraying drying treatment device, the force receiving member one 41a and the guide member two 421 are arranged, the spiral groove one 4211 is 0.25 turns, corresponding to the whole circle 360 ° is 90 °, the force receiving member one 41a is engaged in the guide member two 421 based on the guide protrusion 411 and the spiral groove one 4211, when the guide member two 421 and the force receiving member one 41a are completely connected, the tooling 4 attached thereto should be rotated by 90 ° based on the base frame 42.

[0066] As a preferred embodiment, the toolings 4 located below are fixedly connected to each other, and are synchronously lifted and controlled by the external telescopic driving member; the telescopic driving member is a hydraulic cylinder, and the lifting of the tooling 4 is precisely controlled by an external oil supply system.

[0067] In summary, the working principle of the present application is as follows: during the spraying and drying treatment of automobile parts, the tooling 4 is selected according to the structure and size of the workpiece, if the structure and size of the workpiece are small, the workpiece is directly fixed on the tooling 4 located above, and if the structure and size of the workpiece are large, the workpiece is fixed on the tooling 4 located below, at this time, the tooling 4 located below is moved upward to the position of the tooling 4 located above, and then the position of the tooling 4 is fixed, after the position of the tooling 4 is fixed, the conveying mechanism 3 is started, the tooling 4 is sent into the inside of the spraying chamber 1 and the drying chamber 2 by the conveying mechanism 3, and the spraying and drying processes are sequentially performed, so that the processing of automobile parts is realized.

[0068]

[0069] It should be noted that the present application is a kind of automobile parts spraying drying treatment device, by setting the engaging driving part 6, in the process of spraying or drying the parts to be machined, when the tool 4 moves to engage with the transmission chain 61, the motor 62 can be started at this time to drive the adjusting frame 622 to rotate at a certain speed, so that the rotation speed of the tool 4 driven by the parts to be machined is more appropriate.

[0070] Among them, the motor 62 is a servo motor, and the cascade speed reducer drives the sprocket 621. Based on the programmability of the servo motor, the rotation speed of the sprocket 621 can be controlled to drive the tool 4 at different speeds by the transmission chain 61.

[0071] As a preferred embodiment, the adjusting frame 622 is slidingly connected to the rack of the motor 62, and a bolt assembly is arranged therebetween for fastening. When the adjusting frame 622 is extended, the transmission chain 61 is pulled, and the state of the transmission chain 61 is guided and changed by the adjusting frame 622, as shown in the structure state of Figure 10 The transmission chain 61 is inclined relative to the engaging surface of the tool 4, which can make the tool 4 more smoothly engage with the transmission chain 61.

[0072]

[0073] Further, the turning piece 43 in the tool 4 of the automobile part spraying and drying treatment device is fixedly installed at the lower end of the sliding seat 431 of the conveying mechanism 3, the sliding frame 432 is fixedly connected to the lower end of the base frame 42 or is directly formed on the base frame 42, and the sliding frame 432 is slidingly connected to 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 turning angle of the tool 4 is exactly 90°.
