[0002] There are two main types of existing high-speed rail arm support tubes, square strip-shaped and then round tube-shaped support tubes. When processing, usually a long blank tube is subjected to processing steps such as drilling, chamfering and cutting to finally produce a finished support tube; among them, when processing the round tube-shaped high-speed rail arm support tube, especially when the large-diameter round tube-shaped support tube is symmetrically punched, the drill bit of the drilling equipment cannot penetrate the round tube-shaped support tube due to the relatively large diameter of the round tube-shaped support tube, so that the round tube-shaped support tube needs to be manually rotated 180°. Among them, there are the following defects in manually rotating the circular tubular support tube: manually rotating the circular tubular support tube will increase the workload of workers, and is time-consuming and labor-intensive, reducing the efficiency of drilling holes in the circular tubular support tube; at the same time, when manually rotating the circular tubular support tube, it is considered that factors are relatively large, resulting in the circular tubular support tube rotating less than 180° or greater than 180°, thereby causing the holes drilled in the circular tubular support tube to be asymmetric, affecting the quality of the circular tubular support tube; therefore, a processing and production device for high-speed rail wrist arm support tubes is proposed to solve the above problems.

An air inlet pipe 30 is provided on the sealed box 11, and a one-way air inlet valve 31 is provided on the air inlet pipe 30.

[0039] Working principle: When the present invention is used, the high-speed rail wrist arm support tube is first placed between the clamp plate 1 4 and the clamp plate 2 7, and then the handle is turned to drive the screw rod 19 to rotate, thereby driving the clamp plate 2 7 to move, so that the two rotating plates 5 clamp and fix the high-speed rail wrist arm support tube; then the linear motor 2 is driven to drive the movable plate 3 to move through the operation of the linear motor 2, thereby driving the high-speed rail wrist arm support tube to move, so that the position where the high-speed rail wrist arm support tube needs to be drilled is moved to below the drill bit of the drilling device 15; finally, the drilling device 15 and the electric push rod 9 are opened, and the movable end of the electric push rod 9 moves downward to drive the drilling device 15 to move downward, and finally a hole is drilled on the high-speed rail wrist arm support tube by opening the drilling device 15;

[0040] When drilling a hole in the high-speed rail arm support pipe, the drive motor 16 is started to rotate the output shaft of the drive motor 16 in a clockwise direction, and the output shaft of the drive motor 16 rotates in a clockwise direction to drive the short shaft 2, the connecting plate 1 22, the rotating shaft 27 and the connecting plate 2 28 to rotate, thereby driving the connecting shaft 23 to rotate, thereby driving the connecting rod 26 and the sealing plate 25 to reciprocate; when the sealing plate 25 moves toward one end close to the drive motor 16, at this time, the outside air enters the sealing box 11 through the air inlet pipe 30, and when the sealing plate 25 moves away from the end of the drive motor 16, at this time, the gas in the sealing box 11 is transported to the annular air cavity 20 through the air guide pipe 10, and finally, it is blown into the drill bit of the drilling equipment 15 through the air outlet pipe 14, thereby realizing the cooling of the drill bit in the drilling equipment 15 and improving the service life of the drill bit in the drilling equipment 15;

[0041] When the output shaft of the driving motor 16 rotates clockwise, the ratchet 37 and the pawl 36 cooperate with each other, and the rotation of the connecting shaft 23 does not drive the quarter gear 29;

[0042] At the same time, after a hole is punched at one end of the high-speed rail arm support tube, the linear motor 2 is continued to be controlled to move the other end of the high-speed rail arm support tube to the bottom of the drilling device 15, and then a hole is punched on the high-speed rail arm support tube through the drilling device 15;

[0043] When all the holes on the upper part of the high-speed rail wrist arm support tube are drilled, at this time, the drive motor 16 is controlled to make the output shaft of the drive motor 16 rotate counterclockwise, and at this time, with the cooperation of the pawl 37 and the pawl 36, the connecting shaft 23 will drive the quarter gear 29 to rotate when rotating, thereby driving the unlocking piece 35 to rotate; and when the slide bar 34 slides in the fixing groove 3501, at this time, the fixing rod 33 is inserted into the fixing hole of the rotating plate 5 to fix the rotating plate 5; and when the slide bar 34 slides in the unlocking groove 3502, at this time, the fixing rod 33 moves slowly outward; when the slide bar 34 moves to the stable groove 3503, at this time, the fixing rod 33 is separated from the fixing hole; The teeth on the one-quarter gear 29 mesh with the gear 24; as the slide bar 34 slides in the stable groove 3503, the one-quarter gear 29 drives the gear 24 to rotate, and then drives the short shaft 32 to rotate, thereby driving the rotating plate 5 to rotate, thereby realizing the rotation of the high-speed rail wrist arm support tube, when the slide bar 34 moves from the stable groove 3503 to the return groove 3504, at this time, after the one-quarter gear 29 is separated from the gear 24, the gear 24 will not rotate, and the high-speed rail wrist arm support tube rotates 180°, realizing symmetrical drilling on the high-speed rail wrist arm support tube; at the same time, the fixing rod 33 is quickly inserted into the fixing hole of the rotating plate 5 under the action of the extrusion spring 21, to fix the rotating plate 5;

[0044] Then, the output shaft of the driving motor 16 is rotated clockwise, and the drilling equipment 15 is used to punch holes in the high-speed rail wrist arm support tube; when the holes in the high-speed rail wrist arm support tube are punched, the handle is turned to reset the splint 14 to unlock the high-speed rail wrist arm support tube, which is convenient for unloading the high-speed rail wrist arm support tube.
