A painting line turn around hanger

Abstract

This utility model discloses a steering suspension frame for a painting line, including a mounting frame. A drive screw is rotatably fitted to the inner wall of the mounting frame, and a moving block is threaded onto the drive screw. A rotating rod is rotatably fitted to the lower side of the moving block, and a steering mechanism is provided between the rotating rod and the mounting frame. A square groove is formed on the lower side of the rotating rod. This utility model, by incorporating components such as an electric telescopic cylinder, a lower pressure plate, and an undulating ring, allows control of the electric telescopic cylinder, causing the lower pressure plate to abut against the gap of the undulating ring. During this interaction, a tension spring pulls the square block back to its original position, resulting in up-and-down vibration of the suspension disc during rotation. When spraying items with gaps, this vibration allows the paint to better penetrate into the gaps, enhancing paint adhesion and preventing poor paint adhesion due to poor paint-workpiece adhesion or inability to penetrate gaps, thus improving processing quality.

Description

Technical Field

[0001] This utility model relates to the technical field of painting line suspension brackets, specifically a painting line steering suspension bracket. Background Technology

[0002] A coating line is a production line used to perform surface coating treatment on various workpieces. During the coating process, multiple nozzles are usually set up on the line, and a suspension frame is installed on the coating line. When the coating line is running, the suspension frame moves in an orderly manner along a predetermined track and performs corresponding rotation operations during the movement. This combination of movement and rotation greatly expands the spraying range of the nozzles on the workpiece, thereby enabling all-round spraying of the workpiece.

[0003] In daily use, the workpiece is fixed on the suspension frame, and then the suspension frame and the workpiece are moved by the corresponding drive equipment. During the movement, the workpiece rotates and comes into contact with multiple nozzles on the spraying line, thereby achieving all-round spraying. However, when spraying items with gaps or grooves, the internal gap space is often quite narrow. After the paint is sprayed from the spray gun, it exists in the form of mist. Without external force, the paint particles have difficulty penetrating into these narrow gaps on their own and cannot fill them. As a result, there is basically no paint coverage inside the gaps, which affects the overall coating quality. Therefore, it is necessary to design a coating line steering suspension frame that is highly practical and can improve the painting quality. Utility Model Content

An extension plate is fixedly connected to one side of the moving block, and an electric telescopic cylinder is fixedly connected to the extension plate. A lower pressure plate is fixedly connected to the output end of the electric telescopic cylinder. An undulating ring that cooperates with the lower pressure plate is fixedly connected to the upper side of the suspension plate. A tension spring is provided between the square block and the square groove. Two guide openings are provided on the rotating rod, and a tightening mechanism that cooperates with the lower pressure plate is provided on the inner wall of the two guide openings.

[0007] According to the above technical solution, the steering mechanism includes a toothed plate fixedly connected to one side of the inner wall of the mounting frame, and a gear fixedly connected to the rotating rod and meshing with the toothed plate.

[0008] According to the above technical solution, the fixing component includes a tightening groove formed on the lower side of the suspension plate, a bidirectional lead screw rotatably engaged with the inner wall of the tightening groove, and two suspension blocks threaded onto the bidirectional lead screw.

[0009] According to the above technical solution, the tightening mechanism includes a force-bearing plate that slides on the inner wall of the two guide ports and is fixedly connected to the square block, a force-bearing ring that is fixedly connected to the opposite side of the two force-bearing plates, and an extrusion block that is fixedly connected to one side of the lower pressure plate and cooperates with the force-bearing ring.

[0012] According to the above technical solution, a stepper motor is fixedly connected to one side of the mounting bracket, and the stepper motor cooperates with the drive screw.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. This utility model, by incorporating components such as an electric telescopic cylinder, a lower pressure plate, and an undulating ring, enables control of the electric telescopic cylinder to abut against the gap between the lower pressure plate and the undulating ring. During their interaction, a tension spring pulls and resets the square block, thereby causing the suspension disc to vibrate up and down during rotation. When spraying items with gaps, this vibration allows the paint to better penetrate into the gaps, enhancing the paint's adhesion and preventing poor paint adhesion due to poor adhesion between the paint and the workpiece or the inability to penetrate the gaps, thus improving processing quality.

[0015] 2. This utility model, by providing a tightening mechanism and a guide port, enables the upward movement of the extrusion block to press the force ring upward during the processing of traditional parts, thereby restricting the suspension plate. This prevents the workpiece from moving up and down due to the vibration of the tension spring during rotation, keeping the square block in a tightened and fixed state relative to the square groove, thus limiting the up and down vibration of the suspension plate and achieving stable fixation of the item to meet different painting requirements.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a painting line steering suspension bracket, including a mounting bracket 1, a drive screw 2 rotatably fitted on the inner wall of the mounting bracket 1, a moving block 3 threadedly fitted on the drive screw 2, a rotating rod 4 rotatably fitted on the lower side of the moving block 3, and a steering mechanism 5 provided between the rotating rod 4 and the mounting bracket 1;

[0025] A square groove 6 is provided on the lower side of the rotating rod 4. A square block 7 is slidably fitted on the inner wall of the square groove 6. A suspension plate 8 is fixedly connected to the lower side of the square block 7. A fixing component 9 is provided on the lower side of the suspension plate 8. An movable opening 10 is provided on the front side of the mounting bracket 1. An extension plate 11 is fixedly connected to one side of the moving block 3. An electric telescopic cylinder 12 is fixedly connected to the extension plate 11. A lower pressure plate 13 is fixedly connected to the output end of the electric telescopic cylinder 12. An undulating ring 14 that cooperates with the lower pressure plate 13 is fixedly connected to the upper side of the suspension plate 8. A tension spring 15 is provided between the square block 7 and the square groove 6. Two guide openings 16 are provided on the rotating rod 4. A tightening mechanism 17 that cooperates with the lower pressure plate 13 is provided on the inner wall of the two guide openings 16.

[0026] Please see Figure 2 The steering mechanism 5 includes a toothed plate 501 fixedly connected to one side of the inner wall of the mounting frame 1 and a gear 502 fixedly connected to the rotating rod 4 and meshing with the toothed plate 501. When the moving block 3 moves, the toothed plate 501 and the gear 502 mesh, thereby driving the gear 502 to rotate on the toothed plate 501, and thus driving the workpiece to turn.

[0027] Please see Figure 3 The fixing component 9 includes a tightening groove 901 opened on the lower side of the suspension plate 8, a bidirectional lead screw 902 rotatably engaged with the inner wall of the tightening groove 901, and two suspension blocks 903 threadedly engaged with the bidirectional lead screw 902. By connecting the corresponding workpiece suspension position with the suspension blocks 903, the two suspension blocks 903 are moved accordingly by rotating the bidirectional lead screw 902, thereby fixing the workpiece.

[0028] Please see Figure 3 The tightening mechanism 17 includes a force-bearing plate 171 that slides on the inner wall of the two guide ports 16 and is fixedly connected to the square block 7, a force-bearing ring 172 that is fixedly connected to the opposite side of the two force-bearing plates 171, and a pressing block 173 that is fixedly connected to one side of the lower pressure plate 13 and cooperates with the force-bearing ring 172. The mechanism is tightened by an electric telescopic cylinder 12, which drives the pressing block 173 to move upward, so that the pressing block 173 presses the force-bearing ring 172 upward without affecting the rotation of the rotating rod 4, thereby fixing the square block 7 and the suspension plate 8.

[0029] Please see Figure 4 The upper side of the extrusion block 173 is provided with a circular groove 18, and the inner wall of the circular groove 18 is fitted with a lubricating bead 19. When the extrusion block 173 extrudes the force ring 172, the lubricating bead 19 inside the circular groove 18 will contact the extrusion block 173, so as to play a lubricating role when the force ring 172 rotates.

[0030] Please see Figure 2 and Figure 3A knob 20 is fixedly connected to one end of the bidirectional lead screw 902. One end of the bidirectional lead screw 902 extends to one side of the suspension plate 8 and rotates in coordination. The bidirectional lead screw 902 can be easily operated by holding the knob 20, which improves the convenience of operating the bidirectional lead screw 902.

[0031] Please see Figure 1 A stepper motor 21 is fixedly connected to one side of the mounting bracket 1. The stepper motor 21 cooperates with the drive screw 2. The output end of the stepper motor 21 can be fixed to one end 2 of the drive screw. By starting the stepper motor 21, the drive screw 2 can be rotated.

[0032] The implementation principle of this application is as follows: In use, the mounting bracket 1 is first installed on the matching painting line. Then, the operator coordinates the corresponding workpiece with the suspension block 903 and drives the bidirectional lead screw 902 to rotate by operating the knob 20. The bidirectional lead screw 902 pushes the suspension block 903 to move accordingly inside the tightening groove 901, thereby fixing and suspending the corresponding workpiece. After suspension, the drive screw 2 is rotated to drive the moving block 3 to move. During the movement of the moving block 3, the gear 502 meshes with the toothed plate 501, thereby driving the rotating rod 4 to rotate during the movement. This allows the fixed workpiece to rotate during the movement, so that it can cooperate with the corresponding processing equipment on the painting line to complete the painting.

[0033] When processing workpieces with gaps that match the vibration frequency of this structure, after the workpiece is fixed, the electric telescopic cylinder 12 is controlled to make its lower pressure plate 13 abut against the gap of the undulating ring 14. When the suspension plate 8 is rotated, the undulating ring 14 will rotate accordingly and cooperate with the lower pressure plate 13. The lower pressure plate 13 presses down on it. After pressing, the square block 7 is pulled back by the tension spring 15, thereby realizing the up and down vibration of the suspension plate 8 during rotation. When spraying items with gaps, this vibration can make the paint penetrate into the gaps better, enhance the paint adhesion, avoid the problem of poor paint adhesion due to poor adhesion between the paint and the workpiece and the inability of the gaps to penetrate, and improve processing efficiency.

[0034] When processing traditional smooth workpieces, the lower pressure plate 13 is retracted by the electric telescopic cylinder 12, causing the extrusion block 173 to move upward and press the force ring 172 upward, overcoming the tension of the tension spring 15. Since the force ring 172 is connected to the square block 7 through the force plate 171, and the square block 7 is fixed to the suspension plate 8, the suspension plate 8 can be restricted, so that the workpiece will not move up and down due to the vibration of the tension spring 15 during rotation. The square block 7 is in a tightened and fixed state relative to the square groove 6, thereby restricting the up and down vibration of the suspension plate 8, achieving stable fixation of the item, and meeting different painting requirements.
