[0026] The utility model provides a numerical control pipe thread automatic loading and unloading auxiliary feeding machine. By arranging a loading rack and an unloading rack, there is a transition storage rack between the loading rack and the unloading rack. A first lifting rack is arranged in front of the loading rack, and its bottom is driven by a first hydraulic cylinder. There is a second lifting rack behind the unloading rack, and its bottom is driven by a second hydraulic cylinder. When loading, the first hydraulic cylinder is started to push the first lifting rack to rise, and the steel pipe is conveyed from the loading rack to the top of the first lifting rack for transportation. When unloading, the second lifting rack rises, and the steel pipe is conveyed from the top of the second lifting rack to the unloading rack for unloading, eliminating the need for manual loading and unloading and preventing safety accidents during loading and unloading.

[0027] Figures 1-4 Shown is a structural schematic diagram of an implementation manner of a numerical control pipe thread automatic loading and unloading auxiliary feeding machine of the present utility model. Please refer to Figures 1-4 , a numerical control pipe thread automatic loading and unloading auxiliary feeding machine of this implementation manner includes a frame 100, a first lifting rack 200, a second lifting rack 300, a console 400, and a shock-absorbing conveyor chain device 500.

[0028] The frame 100 includes a loading rack 110, an unloading rack 120 installed at the front end of the loading rack 110, and a transition storage rack 130 located between the loading rack 110 and the unloading rack 120. The rear end of the frame 100 is upward and the front end is downward. The height of the rear end of the transition storage rack 130 is the same as the height of the front end of the frame 100. The rear end of the transition storage rack 130 is upward and the front end is downward. The height of the rear end of the unloading rack 120 is the same as the height of the front end of the transition storage rack 130. The rear end of the unloading rack 120 is upward and the front end is downward. Limit plates are installed at the rear end of the loading rack 110 and the front end of the unloading rack 120 to prevent the steel pipe from rolling off the rear end of the loading rack 110 and the front end of the unloading rack 120. Rotating rollers 140 are provided at both ends of the top of the transition storage rack 130.

[0029] The first lifting frame 200 is located between the loading rack 110 and the transition storage rack 130. A first hydraulic cylinder 210 is installed at the bottom of the first lifting frame 200, and a first V-shaped roller 220 is installed at the top of the first lifting frame 200. The first V-shaped roller 220 is connected to the control console 400 located on the side of the loading rack 110. A second V-shaped roller 320 is installed at the top of the second lifting frame 300, and the second V-shaped roller 320 is connected to the control console 400 located on the side of the unloading rack 120. During loading, the steel pipes are placed singly or side by side on the top of the loading rack 110. The first lifting frame 200 shields the front end of the rack 100 to limit the steel pipes on the top of the loading rack 110. By starting the first hydraulic cylinder 210 to drive the first lifting frame 200 to move downward, the steel pipes on the top of the loading rack 110 move along the slope of the loading rack 110 to the top of the first lifting frame 200 and are located on the top of the first V-shaped roller 220. The steel pipes move along the slope of the first V-shaped roller 220 to the center of the first V-shaped roller 220. By starting the control console 400 on the side of the loading rack 110 to drive the first V-shaped roller 220 to rotate, the first V-shaped roller 220 pushes the steel pipes towards the numerical control machine tool for loading. When the steel pipes need to be rotated, start the first hydraulic cylinder 210 to push the first lifting frame 200 to drive the steel pipes to move upward. The top of the first auxiliary roller 230 abuts against the steel pipes until the steel pipes are lifted up to be clamped by the first auxiliary roller 230 and the rotating roller 140. Start the control console 400 to drive the rotating roller 140 and the first auxiliary roller 230 to rotate to rotate the steel pipes.

[0030] The second lifting frame 300 is located between the unloading rack 120 and the transition storage rack 130. A second hydraulic cylinder 310 is installed at the bottom of the second lifting frame 300. When unloading is required, start the second hydraulic cylinder 310 to drive the second lifting frame 300 to move upward until the height of the second lifting frame 300 is the same as that of the unloading rack 120. The steel pipes move from the top of the second lifting frame 300 to the top of the unloading rack 120 and move along the top of the unloading rack 120 to the position of the limiting plate for limiting.

[0031] There are two control consoles 400, which are respectively installed on the sides of the loading rack 110 and the unloading rack 120. The control console 400 located on the side of the loading rack 110 is connected to the first hydraulic cylinder 210, and the control console 400 located on the side of the unloading rack 120 is connected to the second hydraulic cylinder 310. The control console 400 is internally provided with an electrical control system. The action instructions are given by the overall control of the lathe PLC, and the latter performs secondary control according to the instruction requirements, sends the steel pipes into the lathe for processing, and then retreats and goes offline.

[0032] The shock-absorbing conveyor chain device 500 is respectively installed on the tops of the first lifting frame 200 and the second lifting frame 300. The shock-absorbing conveyor chain device 500 located on the top of the first lifting frame 200 is connected to the control console 400 located on the side of the loading rack 110, and the shock-absorbing conveyor chain device 500 located on the top of the second lifting frame 300 is connected to the control console 400 located on the side of the unloading rack 120. When the steel pipe moves to the top of the transition storage rack 130, the shock-absorbing conveyor chain device 500 positions the steel pipe. When it is necessary to continue transporting the steel pipe, the shock-absorbing conveyor chain device 500 is started to drive the conveyor wheel 510 to rotate, and the conveyor wheel 510 pushes the steel pipe to move in the direction of the unloading rack 120.

[0033] Although the present utility model has been described above with reference to the embodiments, various improvements can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed by the present utility model can be combined with each other in any way. The exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
