A number of sliding seats are equidistantly distributed between the two fixing seats, and the sliding seats are slidably mounted on the installation plate. A number of lifting seats are also provided above the installation plate; a lifting seat is distributed between the fixing seat and the sliding seat, and between two adjacent sliding seats. The bottom of the lifting seat is hinged with two adjusting connecting rods, and the ends of the adjusting connecting rods far away from the lifting seat are respectively hinged to the fixing seat or the sliding seat. A rotating disk is also rotatably mounted on the top of the lifting seat. The bottom ends of the adjusting rods in each group of positioning modules are respectively connected to the corresponding rotating disks.

[0009] Further technical solution, both of the two mounting covers are slidably mounted on the frame, and an opening and closing unit for driving the two mounting covers to move towards or away from each other simultaneously is also provided at the bottom of the frame.

[0010] Further technical solution, the opening and closing unit includes a sliding block installed at the bottom of the mounting cover and an L-shaped push rod installed on the side wall of the installation plate.

The lifting seat can drive the adjusting rods in each group of positioning modules to move upward synchronously through the rotating disc. In the initial stage, since the side pressing plates in each group of positioning modules do not contact the inner wall of the tubular aluminum alloy fitting, at this time, the forces on each lifting seat are the same and they move upward synchronously. During the upward movement of the adjusting rod, it will push the corresponding side pressing plate to move along the radial direction of the rotating seat through the transmission connecting rod, so that the side pressing plate abuts against the inner wall of the tubular aluminum alloy fitting. Since the inner diameters of tubular aluminum alloy fittings of different specifications are different, the positioning module corresponding to the tubular aluminum alloy fitting with a smaller inner diameter will fix it first and keep it in a vertical state, and the lifting seat corresponding to this group of positioning modules will no longer continue to move upward. At this time, the adjusting connecting rod connected to this lifting seat will act on the sliding seat connected to its end and push it to slide laterally, so that the two adjusting connecting rods at the bottom of the adjacent lifting seats are pushed to contract the included angle, so that the remaining lifting seats can continue to move upward until all the positioning modules fix the corresponding tubular aluminum alloy fittings, that is, the positioning of all tubular aluminum alloy fittings is completed. Then drive each rotating seat to rotate through the driving unit, so as to drive the tubular aluminum alloy fittings to rotate synchronously and cooperate with the spraying unit for spraying.

Detailed implementation manners

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the attached drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0026] As Figures 1-6 shown, a surface baking paint treatment device for aluminum alloy fittings provided by an embodiment of the present invention includes a frame 1, and further includes:

[0027] a painting module 2, the painting module 2 includes two symmetrically mounted mounting covers 21 on the frame 1, and both of the two mounting covers 21 are provided with spraying units for spraying paint on tubular aluminum alloy fittings;

[0028] The positioning module 3, there are multiple groups of the positioning module 3, and each group of the positioning module 3 is installed side by side on the frame 1. The positioning module 3 includes a rotating seat 31 rotatably installed on the frame 1, and a driving unit 5 for driving the rotating seat 31 to rotate is further provided at the bottom of the frame 1. A column 32 is installed on the top of the rotating seat 31. A number of adjusting rods 33 are arranged in a circumferential array on the column 32, and each of the adjusting rods 33 is slidably installed on the column 32 along the axial direction of the column 32 (i.e., the vertical direction). A number of side pressing plates 34 are also arranged in a circumferential array around the column 32, and the number of the side pressing plates 34 is the same as that of the adjusting rods 33 and corresponds to each other. Each of the side pressing plates 34 is slidably installed on the rotating seat 31 along the radial direction of the rotating seat 31. A transmission connecting rod 35 is hinged on each of the adjusting rods 33, and the end of the transmission connecting rod 35 away from the adjusting rod 33 is hinged on the side pressing plate 34;

[0029] The control module 4, the control module 4 includes a mounting frame 41 installed at the bottom of the frame 1. A mounting plate 42 is slidably installed on the mounting frame 41 in the vertical direction, and a driving member 43 for driving the mounting plate 42 to slide up and down in the vertical direction is further provided on the mounting frame 41. A fixing seat 44 is respectively arranged at both ends of the mounting plate 42. A number of sliding seats 45 are equidistantly distributed between the two fixing seats 44, and the sliding seats 45 are slidably installed on the mounting plate 42 (it can slide along the direction connecting the two fixing seats 44). A number of lifting seats 47 are further provided above the mounting plate 42; A lifting seat 47 is distributed between the fixing seat 44 and the sliding seat 45, and between two adjacent sliding seats 45. The bottom of the lifting seat 47 is hinged with two adjusting connecting rods 46, and the ends of the adjusting connecting rods 46 away from the lifting seat 47 are respectively hinged on the fixing seat 44 or the sliding seat 45. A rotating disc 48 is rotatably installed on the top of the lifting seat 47. The bottom ends of the adjusting rods 33 in each group of the positioning modules 3 are respectively connected to the corresponding rotating discs 48.

[0030] In an embodiment of the present invention, the driving member 43 can be one of a pneumatic telescopic rod, an electric telescopic rod, or a hydraulic telescopic rod in the prior art. It is placed in the vertical direction, and its telescopic end is connected to the mounting plate 42. During use, the operator only needs to place each tubular aluminum alloy fitting on the rotating seat 31 respectively, and make the side pressing plate 34 located inside the tubular aluminum alloy fitting. Then, only by driving the mounting plate 42 to move upward through the driving member 43, the mounting plate 42 can drive the fixed seat 44 and the sliding seat 45 to move upward synchronously, so as to drive the lifting seat 47 to move upward through the driving member 43. The lifting seat 47 can drive the adjusting rods 33 in each positioning module 3 to move upward synchronously through the rotating disc 48. In the initial stage, since the side pressing plates 34 in each positioning module 3 do not contact the inner wall of the tubular aluminum alloy fitting, at this time, the forces on each lifting seat 47 are the same and they move upward synchronously. During the upward movement of the adjusting rod 33, it will push the corresponding side pressing plate 34 to move along the radial direction of the rotating seat 31 through the transmission connecting rod 35, so that the side pressing plate 34 abuts against the inner wall of the tubular aluminum alloy fitting. Since the inner diameters of tubular aluminum alloy fittings of different specifications are different, the positioning module 3 corresponding to the tubular aluminum alloy fitting with a smaller inner diameter will fix it first to keep it in a vertical state, and the lifting seat 47 corresponding to this group of positioning modules 3 will no longer continue to move upward. At this time, the adjusting connecting rod 46 connected to this lifting seat 47 will act on the sliding seat 45 connected to its end and push it to slide laterally, so that the two adjusting connecting rods 46 at the bottom of the adjacent lifting seat 47 are pushed to contract the included angle, so that the remaining lifting seats 47 can continue to move upward until all the positioning modules 3 fix the corresponding tubular aluminum alloy fittings, that is, the positioning of all tubular aluminum alloy fittings is completed.

[0031] Then, the driving unit 5 drives each rotating seat 31 to rotate, so as to drive the tubular aluminum alloy fittings to rotate synchronously, and cooperate with the spraying unit for spraying, and uniform painting of the tubular aluminum alloy fittings can be realized.

[0032] As Figure 2 、 Figure 6 and Figure 7 shown, as a preferred embodiment of the present invention, both of the mounting covers 21 are slidably mounted on the frame 1, and a opening and closing unit 6 for driving the two mounting covers 21 to move towards or away from each other simultaneously is further provided at the bottom of the frame 1.

[0033] In the embodiment of the present invention, the opening and closing unit 6 can drive the two mounting covers 21 to move towards or away from each other simultaneously, thereby adjusting the distance between the two mounting covers 21. When installing the tubular aluminum alloy fitting, the opening and closing unit 6 drives the two mounting covers 21 to move in opposite directions, so that the distance between the two mounting covers 21 is maximized. At this time, the tubular aluminum alloy fitting can be conveniently placed on the positioning module 3. When painting operation is to be carried out, the opening and closing unit 6 drives the two mounting covers 21 to approach each other, and finally the two mounting covers 21 are in contact with each other to form a sealed space, thereby preventing the paint from overflowing.

[0034] As Figure 2 , Figure 6 and Figure 7 shown, as a preferred embodiment of the present invention, the opening and closing unit 6 includes a sliding block 62 installed at the bottom of the mounting cover 21, and an L-shaped push rod 61 installed on the side wall of the mounting plate 42. The sliding block 62 is slidably installed on the frame 1, and the sliding block 62 is connected to the frame 1 through a return spring 63. An inclined surface 621 is provided at the bottom of the sliding block 62.

[0035] In the embodiment of the present invention, when the mounting plate 42 is at the lower limit position, the top of the L-shaped push rod 61 will abut against the inclined surface 621, and at this time, the distance between the two mounting covers 21 is the largest. As the mounting plate 42 moves upward, the L-shaped push rod 61 will move upward synchronously. Through the cooperation of the L-shaped push rod 61 and the inclined surface 621, the mounting cover 21 can be pushed to move towards the side close to the middle position of the frame 1, so that the two mounting covers 21 approach each other and abut. As the L-shaped push rod 61 continues to move upward, the L-shaped push rod 61 will disengage from the inclined surface 621 and always contact the outer side wall of the sliding block 62 (defining the side of the sliding block 62 away from the middle of the frame 1 as the outer side), thereby limiting the sliding block 62 and ensuring that the two mounting covers 21 always remain in contact with each other.

[0036] After the painting is completed, the mounting plate 42 will move downward, thereby driving the L-shaped push rod 61 to move downward synchronously. When the top end of the L-shaped push rod 61 moves to the inclined surface 621, under the action of the elastic restoring force of the return spring 63, the sliding block 62 will gradually return to the initial position, thereby driving the two mounting covers 21 to move in opposite directions to the initial position.

[0037] As Figure 1 , Figure 2 and Figure 6As shown, as a preferred embodiment of the present invention, the spraying unit includes a spray head 23 and a main pipeline 24. A plurality of spray heads 23 are provided on one side of each of the two mounting covers 21 facing each other. The main pipeline 24 is arranged at the bottom of the frame 1, and the main pipeline 24 is connected to an external paint supply device through a corrugated expansion pipe 25. A plurality of branch pipelines 22 are connected to the main pipeline 24, and each of the branch pipelines 22 is respectively connected to the spray heads 23 in the same vertical direction.

[0038] In the embodiment of the present invention, the spray heads 23 are arranged along the axial direction of the tubular aluminum alloy fitting, and the number of columns is the same as the number of groups of the positioning module 3. The number of branch pipelines 22 is also the same as the number of groups of the positioning module 3, and each of the spray heads 23 in the same column is connected to the same branch pipeline 22. During spraying, the external paint supply device transports the paint liquid to the main pipeline 24 through the corrugated expansion pipe 25, then transports the paint liquid to each branch pipeline 22 through the main pipeline 24, and finally transports the paint liquid to the spray heads 23 through the branch pipelines 22, and sprays the tubular aluminum alloy fitting through the spray heads 23.

[0039] As Figure 2 and Figure 4 shown, as a preferred embodiment of the present invention, a transmission sleeve 311 is provided at the bottom of each of the rotating seats 31, and the driving unit 5 is in transmission connection with the transmission sleeve 311.

[0040] In the embodiment of the present invention, the outer diameter of the transmission sleeve 311 is smaller than the diameter of the rotating seat 31, and the inner diameter dimension thereof needs to include each adjusting rod 33 therein. While ensuring transmission, it provides necessary avoidance space for the installation of components, and while ensuring that each function can be smoothly realized, the structure of the device is made more compact.

[0041] As Figure 4 shown, as a preferred embodiment of the present invention, the driving unit 5 includes a driving motor 51 installed at the bottom of the frame 1. The output end of the driving motor 51 is in transmission connection with any one of the transmission sleeves 311 through a transmission member 52, and the adjacent two transmission sleeves 311 are also in transmission connection through the transmission member 52.

[0042] In the embodiment of the present invention, the transmission member 52 is a belt and pulley mechanism. During use, the output end of the driving motor 51 can drive the transmission sleeve 311 connected thereto to rotate through the transmission member 52, and the transmission sleeves 311 can also rotate synchronously through the transmission member 52, so as to drive the tubular aluminum alloy fittings on each group of positioning modules 3 to rotate synchronously, making the spraying more uniform.

[0043] Working principle: When in use, the operator only needs to place each tubular aluminum alloy fitting on the rotating seat 31 respectively, and make the side pressing plate 34 located inside the tubular aluminum alloy fitting. Then, only by driving the driving member 43 to drive the mounting plate 42 to move upward, the mounting plate 42 can drive the L-shaped push rod 61 to move upward synchronously. Through the cooperation of the L-shaped push rod 61 and the inclined surface 621, the mounting cover 21 can be pushed to move towards one side close to the middle position of the frame 1, so that the two mounting covers 21 approach each other and abut. At the same time, the mounting plate 42 can drive the fixed seat 44 and the sliding seat 45 to move upward synchronously, so as to drive the lifting seat 47 to move upward through the driving member 43. The lifting seat 47 can drive the adjusting rods 33 in each positioning module 3 to move upward synchronously through the rotating disk 48. In the initial stage, since the side pressing plates 34 in each positioning module 3 do not contact the inner wall of the tubular aluminum alloy fitting, at this time, the forces on each lifting seat 47 are the same and they move upward synchronously. During the upward movement of the adjusting rod 33, it will push the corresponding side pressing plate 34 to move along the radial direction of the rotating seat 31 through the transmission connecting rod 35, so that the side pressing plate 34 abuts against the inner wall of the tubular aluminum alloy fitting. Since the inner diameters of tubular aluminum alloy fittings of different specifications are different, the positioning module 3 corresponding to the tubular aluminum alloy fitting with a smaller inner diameter will fix it first and keep it in a vertical state, and the lifting seat 47 corresponding to this group of positioning modules 3 will no longer continue to move upward. At this time, the adjusting connecting rod 46 connected to this lifting seat 47 will act on the sliding seat 45 connected to its end and push it to slide laterally, so that the two adjusting connecting rods 46 at the bottom of the adjacent lifting seat 47 are pushed to contract the included angle, so that the remaining lifting seats 47 can continue to move upward until all the positioning modules 3 fix the corresponding tubular aluminum alloy fittings, that is, the positioning of all tubular aluminum alloy fittings is completed.

[0044] Then start the driving motor 51. The driving motor 51 drives the transmission sleeve 311 connected to it to rotate through the transmission member 52. The transmission sleeves 311 can also rotate synchronously through the transmission member 52, so as to drive each rotating seat 31 to rotate. The rotating seat 31 can drive the tubular aluminum alloy fitting to rotate synchronously, and cooperate with the spraying unit for spraying, so as to realize uniform painting of the tubular aluminum alloy fitting.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
