Description

Technical Field

[0001] This utility model relates to the field of dual-control equipment technology, specifically to an automatic control dual-spindle transmission mechanism. Background Technology

[0002] As key components of hydraulic cylinders, the welding of the cylinder barrel and flange is currently the mainstream method, where a robotic arm controls the spindle rotation of a machine tool via its seventh axis to achieve the welding. To improve automated welding efficiency, the main approach is to add a dual-station welding machine tool, allowing one robotic arm to control two machine tools. However, this requires enabling an eighth axis control function for the robotic arm, and the equipment needs to be equipped with an eighth-axis servo motor, servo driver, and expansion cards to achieve overall equipment control functionality; this investment is relatively high.

[0003] Therefore, an automatic control dual-spindle drive mechanism is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic control dual-spindle transmission mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic control dual-spindle transmission mechanism includes a protective cover, an inner frame, a driven gear for a motor rotatably mounted inside the frame via a main connecting shaft, a first rotary pneumatic chuck mounted at one end of the main connecting shaft, a second rotary pneumatic chuck mounted at the other end of the main connecting shaft, a first rotary pneumatic chuck fixedly connected at one end to a left-position connecting flange via a left-position drive shaft, and a second rotary pneumatic chuck fixedly connected at one end to a right-position connecting gear via a right-position drive shaft. A motor is fixedly mounted on one side of the frame, a reducer is driven at the output end of the motor, and a drive gear for the motor is driven at the output end of the reducer.

[0007] As a preferred embodiment of this utility model, the motor drive gear is meshed with the rotary pneumatic chuck.

[0008] As a preferred embodiment of this utility model, bearings are provided at the connection points between the main connecting shaft, the left station transmission shaft, and the right station transmission shaft and the frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. In this utility model, a motor drives a reducer, which in turn drives the motor's drive gear to rotate. The drive gear then drives the driven gear, which in turn rotates the main connecting shaft. By controlling the contraction of the rotary pneumatic chucks (first and second), the connection and disconnection between the main connecting shaft and the left and right workstation drive shafts are controlled, achieving synchronous rotation of the motor gear ratio of the left main shaft with the chuck for welding. The same applies to the right workstation. The left and right workstations rotate independently and do not affect each other. Working on one workstation does not affect the loading and unloading of materials on the other, thus significantly improving welding efficiency. Attached Figure Description

[0021] An automatic control dual-spindle transmission mechanism includes a protective cover 1, an inner frame 10, and a motor driven gear 3 rotatably mounted inside the frame 10 via a main connecting shaft 6. A rotary pneumatic chuck 1-4 is mounted at one end of the main connecting shaft 6, and a rotary pneumatic chuck 2-13 is mounted at the other end. One end of the rotary pneumatic chuck 1-4 is fixedly connected to a left-position connecting flange 11 via a left-position transmission shaft 12, and one end of the rotary pneumatic chuck 2-13 is fixedly connected to a right-position connecting gear 5 via a right-position transmission shaft 14. A motor is fixedly mounted on one side of the frame 10. 9. The output end of motor 9 is equipped with a reducer 8, and the output end of reducer 8 is equipped with a motor drive gear 7. Motor 9 drives reducer 8, which in turn drives motor drive gear 7 to rotate. Motor drive gear 7 drives driven gear 3 to rotate, which in turn drives main connecting shaft 6 to rotate. By controlling the contraction of the rotary pneumatic chuck 13 and rotary pneumatic chuck 2, the connection and disconnection of main connecting shaft 6 with the left station drive shaft 12 and right station drive shaft 14 on both sides are controlled, so that the motor gear ratio of the left main shaft rotates synchronously with the chuck for welding. The same applies to the right station. The rotation of the left and right stations is independent and does not affect each other. The operation of one station does not affect the loading and unloading of materials in the other station, which effectively improves welding efficiency.

[0022] As an example of this utility model, the motor drive gear 7 is meshed with the rotary pneumatic chuck 13.

[0023] As an example of this utility model, bearings 2 are provided at the connection points of the main connecting shaft 6, the left station transmission shaft 12, and the right station transmission shaft 14 with the frame 10.

[0024] Working Principle: During operation, motor 9 drives reducer 8, which in turn drives motor drive gear 7 to rotate. Motor drive gear 7 drives driven gear 3, which in turn drives main connecting shaft 6 to rotate. By controlling the contraction of the rotary pneumatic chuck 13 and rotary pneumatic chuck 2, the connection and disengagement of main connecting shaft 6 with the left and right workstation drive shafts 12 and 14 are controlled, achieving synchronous rotation of the motor gear ratio of the left main shaft with the chuck for welding. The same applies to the right workstation. The rotation of the left and right workstations is independent and does not affect each other. Working on one workstation does not affect the loading and unloading of materials on the other, thus significantly improving welding efficiency.
