Description

Technical Field

[0001] This utility model relates to a top material rotating mechanism for a gas bar outer tube end sealing welding machine, belonging to the technical field of gas bar assembly equipment. Background Technology

[0002] Pneumatic rods primarily utilize the changing states of gas produced during compression within a cylinder tube, and can be widely used in appliances requiring height adjustment. A pneumatic rod mainly consists of a hollow outer tube, a piston, and a piston rod. When processing the hollow outer tube of the pneumatic rod, an end-sealing welding machine is required to seal one end. Traditionally, a sealing ring is first fixed to the inner wall of one end of the outer tube, and then the outer tube is fixed to the fixture of the end-sealing welding machine. Laser welding is then performed at the connection between the sealing ring and the inner wall of the outer tube by controlling the circular motion of the welding torch. This method requires high precision control of the welding robot, especially when welding outer tubes of different diameters, which requires setting different radii for circular motion, making operation difficult. Furthermore, existing end-sealing welding machine fixtures lack automatic ejection functions, requiring manual assembly of the outer tube onto the fixture, resulting in low work efficiency and low automation.

[0003] Therefore, the research objective of this utility model is to provide a top material rotation mechanism for a pneumatic rod outer tube end sealing welding machine. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a top material rotation mechanism for a pneumatic rod outer tube end-sealing welding machine. The mechanism uses an inner support clamp to hold the outer tube from the inner wall, and then uses a motor to drive the inner support clamp to rise and rotate, pushing the outer tube to the welding station for rotational welding.

[0005] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0006] A top material rotation mechanism for a pneumatic rod outer tube end-sealing welding machine is characterized by comprising a frame, a ball screw, a lifting motor, an inner support sleeve, and a rotary motor. The front end of the frame is equipped with a lifting base via a slide rail slider. The ball screw is vertically mounted inside the frame and connected to the lifting base via a connecting plate. The lifting motor is fixedly mounted on the bottom surface of the top of the frame, and its motor shaft is drively connected to the ball screw. The inner support sleeve is rotatably mounted on the lifting base via a bearing seat, its top end extending upwards through the top of the frame, and its bottom end connected to a cylinder via a coupling. The rotary motor is fixedly mounted on the lifting base and drively connected to the inner support sleeve via a synchronous pulley.

[0007] Furthermore, a positioning block is provided on the top surface of the top of the frame, and the top end of the inner support sleeve passes through the top of the frame from the inside of the positioning block.

[0008] Furthermore, both ends of the ball screw are rotatably mounted on the frame via bearing seats.

[0009] Furthermore, the inner support sleeve is provided in two sets, and each set of the inner support sleeve is connected to a cylinder at its bottom end.

[0010] Furthermore, the inner support sleeve includes a hollow outer tube, an inner support clamp, and a push-pull rod. The hollow outer tube is mounted on the lifting base via a bearing seat. The inner support clamp is detachably mounted at the top of the hollow outer tube. The push-pull rod is inserted into the hollow outer tube via a linear bearing, with its top end connected to the inner support clamp and its bottom end connected to the cylinder.

[0011] Furthermore, the inner support clamp includes a push plate and two sets of openable support plates. The push plate has a figure-eight inclined sliding groove on both sides, and its bottom is connected to the push-pull rod. The two sets of support plates are openable and closable at the top of the hollow outer tube and are respectively connected to the sliding groove of the push plate through pins.

[0012] The beneficial effects of this utility model are: the inner support clamp is used to hold the outer tube from the inner wall, and then the inner support clamp is driven by the motor to rise and rotate, pushing the outer tube to the welding station for rotation welding. The sealing welding of the outer tube of the pneumatic rod can be completed without controlling the welding gun to make circular motion, reducing the difficulty of operation; moreover, it has an automatic material ejection function, eliminating the need for manual assembly of the outer tube onto the clamp, resulting in high work efficiency and a high degree of automation.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-7 Further analysis of this utility model is then conducted.

[0022] like Figure 1-7 As shown, a top material rotation mechanism for a pneumatic rod outer tube end sealing welding machine is characterized by comprising a frame 1, a ball screw 2, a lifting motor 3, an inner support sleeve 4, and a rotary motor 5. The front end of the frame 1 is equipped with a lifting base 6 via a slide rail slider. The ball screw 2 is vertically mounted inside the frame 1 and connected to the lifting base 6 via a connecting plate. The lifting motor 3 is fixedly mounted on the bottom surface of the top of the frame 1, and its motor shaft is drively connected to the ball screw 2, driving the ball screw 2 to rotate. The ball screw 2 drives the lifting base 6 to rise or fall via the connecting plate. The inner support sleeve 4 is rotatably mounted on the lifting base 6 via a bearing seat. Its top end can extend upward through the top of the frame 1, and its bottom end is connected to a cylinder 7 via a coupling. The rotary motor 5 is fixedly mounted on the lifting base 6 and is drively connected to the inner support sleeve 4 via a synchronous pulley to drive the inner support sleeve 4 to rotate.

[0023] In this embodiment, preferably, a positioning block 8 is provided on the top surface of the top of the frame 1, and the top end of the inner support sleeve 4 passes through the top of the frame 1 from the inside of the positioning block 8.

[0024] In this embodiment, preferably, both ends of the ball screw 2 are rotatably mounted on the frame 1 via bearing seats.

[0025] In this embodiment, preferably, two sets of inner support sleeves 4 are provided, and the bottom end of each set of inner support sleeves 4 is connected to a cylinder 7.

[0026] In this embodiment, preferably, the inner support sleeve 4 includes a hollow outer tube 41, an inner support clamp 42, and a push-pull rod 43. The hollow outer tube 41 is mounted on the lifting base 6 via a bearing seat. The inner support clamp 42 is closably mounted at the top of the hollow outer tube 41. The push-pull rod 43 is inserted into the interior of the hollow outer tube 41 via a linear bearing. Its top end is connected to the inner support clamp 42, and its bottom end is connected to the cylinder 7. The piston rod of the cylinder 7 pushes the push-pull rod 43 upward, causing the inner support clamp 42 to open and clamp the inner wall of the pneumatic rod outer tube.

[0027] In this embodiment, preferably, the inner support clamp 42 includes a push plate 421 and two sets of openable support plates 422. The push plate 421 has a figure-eight inclined sliding groove 421a on both sides, and its bottom is connected to the push-pull rod 43. The two sets of support plates 422 are openably and closably disposed at the top of the hollow outer tube 41 and are respectively connected to the sliding groove 421a of the push plate 421 through pins. When the piston rod of the cylinder 7 extends, it pushes the push-pull rod 43 to rise and drives the push plate 421 to rise. During the rising process, the figure-eight sliding groove 421a of the push plate 421 forces the two sets of support plates 422 to separate to both sides, thereby realizing the opening action of the inner support clamp 42.

[0028] In use, the following steps are taken: The robotic arm of the end-sealing welding machine's feeding mechanism transfers the outer tube of the pneumatic rod to the positioning block 8 on the frame 1. The lifting motor 3 drives the lifting base 6 to rise a certain distance, thereby causing the inner support sleeve 4 to rise and insert into the outer tube of the pneumatic rod. Then, the piston rod of the cylinder 7 extends, pushing the push-pull rod 43 to rise, and causing the push plate 421 to rise. During the rise, the V-shaped groove 421a of the push plate 421 forces the two sets of support plates 422 to separate to both sides, thereby realizing the opening action of the inner support clamp 42 and clamping the inner wall of the outer tube of the pneumatic rod. Next, the lifting motor 3 drives the lifting base 6 to rise a certain distance, causing the outer tube of the pneumatic rod to rise away from the positioning block 8 and rise to the welding station, so that a certain point at the connection between the outer tube of the pneumatic rod and the sealing ring is aligned with the welding gun. Finally, the rotary motor 5 drives the inner support sleeve 4 to rotate, and causes the outer tube of the pneumatic rod to rotate one revolution. When the outer tube of the pneumatic rod rotates, the welding gun welds the connection between the outer tube of the pneumatic rod and the sealing ring. After welding is completed, the rotary motor 5 stops rotating, and then the lifting motor 3 drives the lifting base 6 to reset, which in turn drives the inner support sleeve 4 to reset. The piston rod of the cylinder 7 retracts and resets, causing the inner support clamp 42 to release the outer tube of the pneumatic rod. Then, the mechanical arm of the end-sealing welding machine's discharge mechanism transfers the outer tube of the pneumatic rod away from the positioning block 8.
