Description

Technical Field

[0001] This utility model relates to the field of production line facilities technology, and more specifically, to a hook and hanger device. Background Technology

[0002] Surface treatment is a process that artificially forms a layer on the surface of a substrate material that has different mechanical, physical, and chemical properties from the substrate. The purpose of surface treatment is to meet the requirements of corrosion resistance, wear resistance, decoration, or other special functions of the product. Spraying and vacuum coating are commonly used surface treatment methods. In order to improve the quality and efficiency of surface treatment, a slide is used to transport the workpiece during spraying or coating.

[0003] Patent document CN222766587U discloses a novel UV spraying production line, including a workbench. A feeding conveyor belt and an unloading conveyor belt are installed on the front side of the workbench. A transmission component for conveying automotive brake discs is fixedly connected to the upper surface of the workbench. A spraying station is fixedly connected to the left side of the upper surface of the workbench. Two limiting rods are fixedly connected to the inner side of the spraying station. A spraying component for spraying the brake discs is slidably connected to the outer surface of the limiting rods. The transmission component in this device is modular and standardized, resulting in low cost, small footprint, and precise positioning. Simultaneous operation of the induction heating mechanism, UV curing mechanism, and spraying component greatly improves work efficiency. The spraying component enables the spray plate to reciprocate on the outer surface of the limiting rods, resulting in more uniform spraying of the brake discs, reduced spraying errors, and a lower scrap rate.

In the first working position, the upper end of the connecting pin 6 is engaged with the first connecting part 7, and in the second working position, the connecting pin 6 is released from engagement with the first connecting part 7 and engaged with the second connecting part 8.

[0034] Furthermore, the shell 5 is a cylindrical shape with an open top, and the bottom plate of the shell 5 has a through hole 51;

[0035] The connecting pin 6 includes an upper connecting part 61 and a lower connecting part 62. The upper connecting part 61 passes through the through hole 51 and is detachably or fixedly connected to the lower connecting part 62.

[0036] Furthermore, a first shoulder 611 is fixedly provided on the upper part of the upper connecting part 61. The shape of the first shoulder 611 is adapted to the shape of the inner wall of the housing 5. A spring 9 is sleeved on the outer circumference of the upper connecting part 61. The upper end of the spring 9 contacts the lower end face of the first shoulder 611, and the lower end of the spring 9 contacts the upper end face of the bottom plate of the housing 5.

[0037] Furthermore, a second shoulder 621 is fixedly provided at the lower part of the lower connecting part 62;

[0038] The auxiliary conveying assembly includes a connecting plate 10, which is movably mounted on the bottom surface of the workbench 1. A power cylinder 11 is fixedly mounted on the lower end surface of the connecting plate 10. A hook 12 is fixedly mounted on the piston rod of the power cylinder 11. The hook 12 extends above the connecting plate 10 and hooks onto the second shoulder 621.

[0039] Furthermore, a connecting block 13 is fixedly installed on the connecting plate 10, and a second connecting part 8 is opened on the upper end surface of the connecting block 13 at a position corresponding to the lower connecting part 62.

[0040] Furthermore, an external thread is provided on the outer circumference of the lower connecting end 612 of the upper connecting part 61, and a threaded hole 622 is provided on the upper end face of the lower connecting part 62, and the external thread is threadedly connected to the threaded hole 622.

[0041] Furthermore, the power cylinder 11 is a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0042] Furthermore, spring 9 is a compression spring.

[0043] The working principle of the above technical solution:

[0044] To address the issue of synchronized workpiece movement between different workstations during spraying operations, a ring belt 4 is installed on the upper surface of the workpiece table 1. Workpieces are transported to different workstations via a work slide 3. Then, a transmission switching unit connects the work slide 3 to the ring belt 4 and switches it to an auxiliary conveyor assembly. The auxiliary conveyor assembly then moves the work slide along the workstation. After the workpiece completes its work at the workstation, the work slide 3 disconnects from the auxiliary conveyor assembly and reconnects to the ring belt 4, moving to the next workstation under the drive of the ring belt 4. This ensures that the movement of workpieces at each workstation is independent and does not interfere with each other, improving the flexibility of workpiece operation and increasing the efficiency of the spraying operation.

[0045] The transmission switching unit includes: a housing 5 fixedly mounted on the working slide plate 3, a connecting pin 6 slidably mounted inside the housing 5, the connecting pin 6 having two working positions when sliding up and down, namely a first working position and a second working position, a first connecting part 7 fixedly mounted on the outer side of the annular belt 4, and a second connecting part 8 opened on the auxiliary transmission component. In the first working position, the upper end of the connecting pin 6 is engaged with the first connecting part 7, and in the second working position, the connecting pin 6 is released from engagement with the first connecting part 7 and engaged with the second connecting part 8.

[0046] The first connecting part 7 can be a retaining ring, which is horizontally set. The outer circumference of the retaining ring near the annular belt 4 is fixedly connected to the annular belt. The circumference of the retaining ring away from the annular belt 4 can be provided with an opening, so that the retaining ring has a certain elasticity and can be easily engaged with the upper end of the connecting pin 6. The second connecting part 8 can be a groove opened on the auxiliary conveying component. The shape of the groove can be circular, annular or square.

[0047] To facilitate the installation of the connecting pin 6, the connecting pin 6 includes an upper connecting part 61 and a lower connecting part 62. The upper connecting part 61 and the lower connecting part 62 can be detachably connected or fixedly connected. The detachable connection can be a threaded connection, a snap-fit, a side screw, or other connection methods. The fixed connection can be a welding, interference fit, or adhesive bonding method. After the spring 9 is inserted into the housing 5 from the top, the upper connecting part 61 is inserted from the top end of the housing 5. The lower end of the upper connecting part 61 protrudes from the bottom end of the housing 5. The lower connecting part 62 is connected to the lower end of the upper connecting part 61. At this time, the upper connecting part 61 moves upward under the action of the spring force, pulling the lower connecting part 61 upward, so that the upper end face of the lower connecting part 61 contacts the lower end face of the housing 5. At this time, the height of the upper end of the upper connecting part 61 is just enough to be inserted into the first connecting part 7 and snapped into the first connecting part 7.

[0048] When the working slide 3 moves between different workstations, it moves on the guide rail 2. The upper end of the connecting pin 6 is inserted into the first connecting part 7. The annular belt 4 drives the working slide 3 to move. When it reaches the corresponding workstation, the lower end of the lower connecting part 62 is aligned with the second connecting part 8, and the second shoulder 621 is located below the hook 12. At this time, the power cylinder 11 is activated. The piston rod of the power cylinder 11 drives the hook 12 to move downward. Under the pulling force of the hook 12, the connecting pin 6 moves downward to the second working position, and the hook 12 hooks the first working position. The two-axis shoulder 621 disengages the upper end of the upper connecting part 61 from the first connecting part 7 and inserts the lower end of the lower connecting part 62 into the second connecting part 8. The working slide 3 can move with the connecting plate 10. The connecting plate 10 is fixedly connected to the piston of the telescopic drive member 101 fixedly installed on the worktable 1. The piston of the telescopic drive member 101 extends or retracts, driving the connecting plate 10 to move, thereby driving the working slide 3 to move on the work station, so that multiple workpieces on the working slide can be operated, such as spraying or UV curing.

[0049] After the work at the workstation is completed, the telescopic drive 101 drives the connecting plate 10 back to the first switching position. At the first switching position, the working slide 3 disengages from the annular belt 4 and connects to the auxiliary conveyor assembly. At this time, the power cylinder 11 is activated, causing its piston to extend. The connecting pin 6 moves upward under the force of the spring 9 to the first working position. The lower end of the lower connecting part 62 disengages from the second connecting part 8, while the upper end of the upper connecting part 61 inserts into the first connecting part 7. Then, the annular belt 4 rotates, driving the working slide 3 to the next workstation. The annular belt 4 stops moving each time a switch is performed.

[0050] The connecting plate 10 is slidably mounted on the bottom surface of the workbench 1. A guide rail is fixedly mounted on the bottom surface of the workbench 1. The connecting plate 10 is slidably connected to the guide rail. Two guide rails can be arranged in parallel to increase the stability of the connecting plate when it slides.

[0051] The beneficial effects of the above technical solution are as follows:

[0052] The hook and hanger device of this utility model, after being transported to the working station by the annular belt, disconnects the transmission connection with the annular belt and switches to the transmission connection with the auxiliary conveyor component at the same time. After the work is completed at the working station, it switches back to the transmission connection with the shaped belt. The movement of the workpieces at each station does not interfere with each other, which improves the work efficiency of surface treatment.

[0053] In one embodiment, such as Figure 6 As shown, an iron sleeve 14 is fixedly installed at the lower part of the lower connecting part 62. The auxiliary conveying component includes a connecting plate 10, which is movably installed on the bottom surface of the workbench 1. A connecting block 13 is fixedly installed on the connecting plate 10. A second connecting part 8 is opened at the position corresponding to the lower connecting part 62 on the upper end surface of the connecting block 13. An electromagnet 15 is fixedly installed inside the second connecting part 8. When the electromagnet 15 is energized, it forms an attraction force with the iron sleeve 14. In order to improve the attraction force of the electromagnet 15, an iron core can be provided in the coil of the electromagnet 15 to conduct magnetism.

[0054] When the work slide 3 moves to a position where a transmission switch is required, the electromagnet 15 is energized. After being energized, the electromagnet 15 forms an attraction with the iron sleeve 14. The attraction of the electromagnet 15 overcomes the elastic force of the spring 9 and attracts the iron sleeve 14 to move downward, thereby driving the connecting pin 6 to move downward. The lower end of the lower connecting part 62 of the connecting pin 6 is inserted into the second connecting part 8. At the same time, the upper connecting part 61 of the connecting pin 6 disengages from the first connecting part 7 of the annular belt 4. The work slide 3 can then move with the auxiliary conveyor assembly. After the work is completed, the auxiliary conveyor assembly is reset, the electromagnet 15 is de-energized, and the connecting pin 6 moves upward under the action of the spring 9. The lower end of the lower connecting part 62 disengages from the second connecting part 8, and the upper end of the upper connecting part 61 is inserted into the first connecting part 7. The annular belt 4 can then transport the work slide 3 to the next work station.
