Technical Field

[0001] The utility model belongs to the technical field of aluminum profile clamping devices, and in particular relates to an aluminum profile circumferential spray paint clamping device. Background Art

[0002] Aluminum profiles are the most widely used type of non-ferrous metal structural materials in industry. They need to be painted before being put into use to achieve corrosion resistance, increase wear resistance and other effects.

[0003] The related technology (publication number CN213102837U) discloses a surface pretreatment paint spraying device for aluminum profiles, which solves the problem that one side of the aluminum profile needs to be manually turned over after painting, which is inconvenient to operate, and the paint exhaust gas pollutes the environment and health. It includes a paint spray box, one side of the paint spray box is connected to a protective shell, and a first motor is installed on one side of the upper part of the protective shell. The output end of the first motor is connected to a first synchronous pulley. The utility model drives the first connecting shaft and the second connecting shaft to rotate by the first motor, thereby driving the aluminum profile clamped by the clamp block to flip, so that the angle of the aluminum profile can be quickly flipped, which is convenient for painting different surfaces. There is no need for manual turning, and the operation is convenient; the exhaust gas generated during the painting process is adsorbed and precipitated by water source, and then filtered through the PP filter element layer, the folded filter element layer and the activated carbon filter element layer in turn, so that the gas is purified to avoid exhaust gas polluting the environment and damaging health.

[0004] In the related art, when positioning the aluminum profile for painting, it is necessary to gradually clamp and position the four side walls of the aluminum profile separately, which makes it difficult to achieve the synchronous positioning of the four circumferential sides of the aluminum profile at one time. In addition, the traditional method of hoisting the aluminum profile for circumferential painting can easily cause the aluminum profile to shake during the hoisting and rotation process, making it difficult to ensure the stability of the aluminum profile and the painting effect. Utility Model Content

[0005] In view of the problems in the prior art that when positioning the aluminum profile for spray painting, the four side walls of the aluminum profile need to be clamped and positioned separately step by step, and it is difficult to achieve the synchronous positioning of the four circumferential sides of the aluminum profile at one time, the utility model provides an aluminum profile circumferential spray painting clamping device, which adopts a unified driving force and can achieve the synchronous positioning of the four side walls of the aluminum profile at one time, eliminating the tedious steps of step-by-step positioning, and the position of the aluminum profile after positioning is stable, which is more conducive to the subsequent stable circumferential rotation of the aluminum profile to achieve circumferential spray painting processing. The specific technical scheme is as follows:

[0006] An aluminum profile circumferential spraying clamping device, comprising a base. On the left and right sides of the top of the base, two relatively movable supporting brackets are symmetrically arranged. The side wall of the supporting bracket is connected to a mounting plate through a rotating assembly. The top of the side wall of the mounting plate is provided with a cylinder. The output end of the cylinder is fixedly connected to a connecting block. The bottom end of the connecting block is fixedly installed with a driving rod. The driving rods are symmetrically arranged before and after relative to the connecting block. A moving seat is slidably sleeved on the outer wall of the driving rod. The moving seat moves in the front and rear directions through a limiting assembly. The bottom end of the side wall of the mounting plate is fixedly installed with a fixed seat. Positioning assemblies are respectively installed on the opposite sides of the outer walls of the moving seat, the fixed seat and the driving rod.

[0007] In the above technical solution, the positioning assembly includes a support rod and a positioning piece. The four positioning pieces are circumferentially arranged at equal intervals.

[0008] In the above technical solution, a stop piece is installed at the free end of the driving rod.

[0009] In the above technical solution, a through groove is formed through the middle of the mounting plate. An aluminum profile is placed through the inner cavity of the through groove. The side wall of the aluminum profile is attached to the side wall of the positioning piece.

[0010] In the above technical solution, the limiting assembly includes a sliding groove opened on the side wall of the mounting plate. A slider is slidably arranged in the inner cavity of the sliding groove. And the slider is fixedly connected to the side wall of the moving seat.

[0011] In the above technical solution, the cross-sectional shape of the slider is set to a dovetail shape.

[0012] In the above technical solution, the rotating assembly includes a rotating shaft rotatably connected to the side wall of the supporting bracket. It also includes a connecting frame fixedly installed on the outer wall of the rotating shaft. And the connecting frame is fixedly connected to the side wall of the mounting plate.

The output end of the second motor is connected to the screw rod.

[0014] The aluminum profile circumferential spraying clamping device of the present utility model, compared with the prior art, has the beneficial effects that:

[0015] 1. When spray painting and positioning aluminum profiles, it is necessary to gradually clamp and position the four side walls of the aluminum profile separately, and it is difficult to achieve synchronous positioning of the four sides of the aluminum profile circumferentially at one time. The utility model can promote four groups of support rods and positioning pieces to form a positioning space through a cylinder, a connecting block, a driving rod, and a moving seat, and synchronously position the side walls around the aluminum profile. Compared with the traditional method of gradually positioning the side walls of the aluminum profile, the utility model adopts the same driving force, can achieve synchronous positioning of the four side walls of the aluminum profile at one time, omits the cumbersome steps of gradual positioning, and the position of the positioned aluminum profile is stable, which is more conducive to the subsequent stable circumferential rotation of the aluminum profile to achieve circumferential spray painting processing;

Detailed implementation manner

[0025] The following combines specific implementation cases and attached Figures 1 to 5 to further illustrate the present utility model, but the present utility model is not limited to these embodiments.

[0026] Refer to Figures 1 to 5 As shown in the figure, an aluminum profile circumferential painting clamping device includes a base 1. On the left and right sides of the top of the base 1, two relatively movable brackets 2 are symmetrically arranged. The side wall of the bracket 2 is connected to a mounting plate 6 through a rotating assembly. The rotating assembly can drive the mounting plate 6 to rotate, so as to realize the circumferential rotation of the positioned aluminum profile for painting. At the top of the side wall of the mounting plate 6, a cylinder 7 is installed. The output end of the cylinder 7 is fixedly connected to a connecting block 8. At the bottom of the connecting block 8, a driving rod 9 is fixedly installed. The driving rod 9 is symmetrically arranged before and after relative to the connecting block 8. A moving seat 12 is slidably sleeved on the outer wall of the driving rod 9. The moving seat 12 moves in the front and rear directions through a limiting assembly. At the bottom of the side wall of the mounting plate 6, a fixed seat 13 is fixedly installed. Positioning assemblies are respectively installed on the opposite sides of the outer walls of the moving seat 12, the fixed seat 13 and the driving rod 9. By opening the cylinder 7, the connecting block 8 and the driving rod 9 are driven to move downward synchronously, so as to prompt the two moving seats 12 on the front and rear to move synchronously towards the middle. The positioning assembly includes a support rod 14 and a positioning piece 15. The four positioning pieces 15 are circumferentially arranged at equal intervals. As the driving rod 9 moves downward, the support rod 14 and the positioning piece 15 connected to the outer wall of the driving rod 9 move downward synchronously. The two moving seats 12 move synchronously towards the middle, prompting the support rod 14 and the positioning piece 15 connected to the side wall of the moving seat 12 to move synchronously towards the middle. Thus, the positioning pieces 15 at the top, front and rear sides and the bottom synchronously clamp and position the peripheral side walls of the aluminum profile. In addition, in order to prevent the driving rod 9 from moving excessively and disengaging from the inner cavity of the moving seat 12, a flap 17 is installed at the free end of the driving rod 9, and the position of the driving rod 9 is limited by means of the flap 17. A through groove 16 is penetrated through the middle of the mounting plate 6. An aluminum profile 18 is placed through the inner cavity of the through groove 16. The side wall of the aluminum profile 18 is attached to the side wall of the positioning piece 15. The peripheral side walls of the aluminum profile 18 can be positioned by the four positioning pieces 15.

[0027] In addition, refer to Figure 5As shown, the limit assembly includes a slide groove 10 opened on the side wall of the mounting plate 6, and a slider 11 is slidably arranged in the inner cavity of the slide groove 10, and the slider 11 is fixedly connected to the side wall of the moving seat 12. The connecting block 8 and the driving rod 9 are driven by the opened cylinder 7 to move downward synchronously, so as to prompt the front and rear moving seats 12 to move synchronously toward the middle. At this time, the slider 11 connected to the side wall of the moving seat 12 moves along the inner cavity of the slide groove 10 to limit the moving direction of the moving seat 12; in order to ensure the stability of the slider 11 in the inner cavity of the slide groove 10, the cross-sectional shape of the slider 11 is set to a dovetail shape, so as to ensure that the slider 11 moves along the inner cavity of the slide groove 10 while ensuring the stability of the slider 11.

[0028] Specific reference Figures 1 to 3 As shown, the rotating assembly includes a rotating shaft 3 rotatably connected to the side wall of the supporting bracket 2, and also includes a connecting frame 5 fixedly installed on the outer wall of the rotating shaft 3, and the connecting frame 5 is fixedly connected to the side wall of the mounting plate 6, and a first motor 4 is installed on the side wall of one of the supporting brackets 2, and the output end of the first motor 4 is connected to one of the rotating shafts 3. If the aluminum profile 18 after clamping and positioning rotates circumferentially, the rotating shaft 3 and the connecting frame 5 are driven to rotate by turning on the first motor 4, so as to cause the mounting plate 6 on the right and the right end of the aluminum profile 18 to rotate, so as to drive the left end of the aluminum profile 18 and the mounting plate 6, the connecting frame 5, and the rotating shaft 3 on the left side to rotate synchronously, so as to realize the circumferential rotation of the aluminum profile 18, so that the subsequent painting device can spray the aluminum profile 18.

[0029] See also Figure 1 and 2 As shown, a groove body is provided on the upper surface of the base 1, and a screw 19 is rotatably connected to the inner cavity of the groove body through a bearing. The threads on the left and right sides of the outer wall of the screw 19 are symmetrical and oppositely arranged. Two moving blocks 20 are threadedly sleeved on the outer wall of the screw 19, and the top of the moving block 20 is fixedly connected to the supporting bracket 2. A second motor 21 is installed on the right side wall of the base 1, and the output end of the second motor 21 is connected to the screw 19. The two ends of the aluminum profile 18 are aligned with the left and right through grooves 16 and placed. The screw 19 is driven to rotate by the turned-on second motor 21 to prompt the two moving blocks 20 threadedly connected at the two ends of the screw 19 to move synchronously toward the middle, so as to prompt the two supporting brackets 2 to move synchronously toward the middle, and prompt the two ends of the aluminum profile 18 to gradually penetrate the inner cavities of the two through grooves 16; when the sprayed aluminum profile 18 is disassembled, the two supporting brackets 2 are prompted to move outward to prompt the aluminum profile 18 to break away from the inner cavities of the two through grooves 16.

[0030] It is worth mentioning that the cylinder 7 used in this application is a self-locking cylinder commonly used on the market, and its output end can stay at any position and be locked; the first motor 4 and the second motor 21 use self-locking motors commonly used on the market with output ends that can be locked. When they stop working, their output ends can self-lock and will not rotate under external force; the above-mentioned existing components will not be described in detail here.

[0031] The working principle of a circumferential painting clamping device for aluminum profiles in this embodiment is as follows:

[0032] Align the two ends of the aluminum profile 18 with the left and right through slots 16 and place them. Drive the screw rod 19 to rotate by starting the second motor 21, so as to prompt the two moving blocks 20 threadedly connected to both ends of the screw rod 19 to move synchronously towards the middle, so as to prompt the two bearing brackets 2 to move synchronously towards the middle, and prompt the two ends of the aluminum profile 18 to gradually penetrate into the inner cavities of the two through slots 16;

[0033] Place the end of the aluminum profile 18 on the upper surface of the positioning piece 15 at the bottom. Drive the connecting block 8 and the driving rod 9 to move synchronously downwards by starting the cylinder 7, so as to prompt the front and rear moving seats 12 to move synchronously towards the middle. At this time, the slider 11 connected to the side wall of the moving seat 12 moves along the inner cavity of the sliding groove 10 to limit the moving direction of the moving seat 12. As the driving rod 9 moves downwards, it drives the support rod 14 and the positioning piece 15 connected to the outer wall of the driving rod 9 to move synchronously downwards. The synchronous movement of the two moving seats 12 towards the middle prompts the support rod 14 and the positioning piece 15 connected to the side wall of the moving seat 12 to move synchronously towards the middle. Thus, the positioning pieces 15 at the top, front and rear sides, and bottom synchronously clamp and position the peripheral side walls of the aluminum profile 18;

[0034] If the circumferentially clamped and positioned aluminum profile 18 rotates circumferentially, drive the rotating shaft 3 and the connecting frame 5 to rotate by starting the first motor 4, so as to prompt the mounting plate 6 on the right side and the right end of the aluminum profile 18 to rotate, so as to drive the left end of the aluminum profile 18 and the mounting plate 6, connecting frame 5, and rotating shaft 3 on the left side to rotate synchronously, realizing the circumferential rotation of the aluminum profile 18, so as to facilitate the subsequent painting device to spray and process the aluminum profile 18;

[0035] This utility model adopts the same driving force, can synchronously position the peripheral side walls of the aluminum profile 18 at one time, omits the cumbersome steps of gradual positioning, and the position of the positioned aluminum profile 18 is stable, which is more conducive to the subsequent stable circumferential rotation of the aluminum profile 18 to realize circumferential painting processing.

[0036] The above are only the preferred embodiments of this utility model and are not used to limit this utility model. For those skilled in the art, this utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this utility model shall be included within the protection scope of this utility model.
