Description

Technical Field

[0001] This utility model relates to the field of air conditioner fin press, and more particularly to a novel servo height adjustment device. Background Technology

[0002] In existing technologies, the height adjustment device commonly used in air conditioner fin presses is achieved by rotating an external handwheel to move the gear set of the height adjustment device. For some air conditioner fin punch presses with simple molds, a single height adjustment can meet the customer's production needs. However, with the continuous development of the air conditioner fin market, there are higher requirements for the adaptability of fin punch presses. Therefore, in order to adapt to various fin molds, the punch press must be able to quickly adjust the mold mounting height. Utility Model Content

[0003] The purpose of this invention is to provide a novel servo-controlled sealing height adjustment device to solve the problems in the prior art.

[0004] The technical solution of this utility model is: a novel servo height adjustment device, the device comprising a servo motor, a reducer, a transmission shaft, a bevel gear set, a gear set, a shock absorber bracket, a drag chain, a threaded sleeve, and a slider;

[0005] The servo motor and reducer are fixed with screws and mounted on the shock absorber bracket. The shock absorber bracket is fixed with the mounting plate with the window on the side of the slider with screws. One end of the drive shaft is connected to the reducer through a tensioning sleeve. The other end of the drive shaft is connected to the bevel gear set. The bevel gear set is connected to the gear set. The gear set is connected to the threaded sleeve to control the forward and reverse rotation of the threaded sleeve. The threaded sleeve and the hydraulic cylinder are engaged with metric threads. The hydraulic cylinder drives the slider to move up and down.

[0006] Furthermore, the shock-absorbing bracket is an L-shaped steel plate bending component.

[0007] Furthermore, the drive shaft has no machined keyway.

[0008] Furthermore, the gear set and the threaded sleeve are connected by a fourth-stage gear transmission to achieve forward and reverse rotation of the threaded sleeve.

[0009] The beneficial effects of this invention are: the vertical height adjustment of the slider can be achieved through a bevel gear transmission and a four-stage gear transmission via the forward and reverse rotation of the servo motor. The entire mechanism is safe and effective, the gear ratio is reasonably designed, and the actual torque during servo motor drive is less than the rated torque, greatly ensuring the service life of the mechanism.

[0011] Figure 2 This is a schematic diagram of the structure of this utility model.

[0012] In the diagram, 1 is the servo motor, 2 is the reducer, 3 is the drive shaft, 4 is the bevel gear set, 5 is the gear set, 6 is the shock absorber bracket, 7 is the cable chain, 8 is the threaded sleeve, and 9 is the slider. Detailed Implementation

[0013] A novel servo-driven height adjustment device includes a servo motor 1, a reducer 2, a transmission shaft 3, a bevel gear set 4, a gear set 5, a shock-absorbing bracket 6, a drag chain 7, a threaded sleeve 8, and a slider 9.

[0014] The servo motor 1 and the reducer 2 are fixed with screws and mounted on the shock absorber bracket 6. The shock absorber bracket 6 is fixed with the mounting plate with the side window of the slider 8 by screws. One end of the drive shaft 3 is connected to the reducer 2 through a tensioning sleeve. The other end of the drive shaft 3 is connected to the bevel gear set 4. The bevel gear set 4 is connected to the gear set 5. The gear set 5 is connected to the threaded sleeve 8 to control the forward and reverse rotation of the threaded sleeve 8. The threaded sleeve 8 is engaged with the hydraulic cylinder using a metric thread. The hydraulic cylinder drives the slider 9 to move up and down.

[0015] The shock-absorbing bracket 6 is an L-shaped steel plate bending component.

[0016] The drive shaft 3 has no machined keyway.

[0017] The gear set 5 and the threaded sleeve 8 are connected by a fourth-stage gear transmission to achieve forward and reverse rotation of the threaded sleeve 8.

[0018] The working principle of this utility model is as follows: The servo motor 1 and the reducer 2 are fixed with screws and then mounted on the shock absorber bracket 6. The shock absorber bracket 6 is fixed with the mounting plate with the side window of the slider 9 using screws. The shock absorber bracket 6 is an L-shaped steel plate bending piece. This piece does not require welding, and its strength is stable after bending. It is connected by a shock absorber pad to further ensure stability. The drive shaft 3 and the reducer 2 are connected using a tension sleeve. No keyway needs to be machined on the drive shaft 3, so the strength of the shaft is not affected. The tension sleeve is a standard part, easy to disassemble and replace, and has strong interchangeability for maintenance. The other end of the drive shaft 3 transmits the torque provided by the servo motor 1 to the vertical gear set 5 through the bevel gear set 4. Finally, the gear set 5 and the threaded sleeve 8 are connected through a fourth-stage gear transmission to achieve the forward and reverse rotation of the threaded sleeve 8. The threaded sleeve 8 and the hydraulic cylinder are engaged by a metric thread, thereby enabling the slider 9 to move up and down.

[0019] During operation, the output electrical signal causes the output shaft of servo motor 1 to rotate. Through the aforementioned reducer 2 and transmission shaft 3, the rotation of the motor shaft is converted into the up-and-down movement of slider 9, controlling the change in the mold mounting height between the lower surface of slider 9 and the upper surface of the worktable to adapt to different mold closing height installation requirements. The servo motor has built-in communication functionality; the power and communication lines of servo motor 1 can be safely and efficiently transferred from slider 9 to the power control cabinet via cable chain 7. On one hand, machine operators can observe the images and parameters on the main control screen to obtain information about the machine's mold mounting height during the operation of the air conditioner fin press. On the other hand, since manual operation is not required, downtime caused by worker intervention is significantly reduced, improving automation while ensuring production efficiency.
