Specific implementation mode

[0024] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the accompanying drawings.

[0025] As Figures 1-3 shown, an automatic loading and unloading mechanism of a hollow chuck lathe includes a truss 1. The extending direction of the truss 1 is set as the first direction. One end of the truss 1 is provided with a lathe 2. A chuck is provided on the lathe 2. A steel pipe passes through the chuck and extends into the lathe 2. A clamping component 4 that moves along the first direction is provided on the truss 1. The clamping component 4 is used to clamp the steel pipe and convey the steel pipe to the lathe or output the steel pipe. The steel pipe is parallel to the axis of the first direction. A plurality of material supporting components 3 are provided below the truss 1. The plurality of material supporting components 3 are distributed along the first direction. The material supporting component 3 includes a V-shaped wheel 36. The V-shaped wheel 36 can move in the vertical direction. The V-shaped wheel 36 does not interfere with the movement of the clamping component 4. The lathe is connected with a controller, and the clamping component 4 is connected with the controller.

[0026] Specifically, under the control of the controller, the clamping component 4 clamps or releases the steel pipe. The clamping component 4 can move along the first direction. The controller calculates a suitable clamping position according to the length of the steel pipe to be processed. The clamping component 4 moves to this position and conveys it to the lathe 2. After receiving the signal, the lathe 2 processes the steel pipe. After the processing is completed, the clamping component 4 re-clamps the steel pipe and pulls the steel pipe out of the lathe 2. The V-shaped wheel 36 on the material supporting component 3 supports the steel pipe. The V-shaped wheel 6 can reduce the friction force when the steel pipe moves. The V-shaped wheel 6 can move in the vertical direction. The height of the V-shaped wheel 6 can be adjusted according to the diameter of the steel pipe to be processed. When the clamping component 4 passes by, the V-shaped wheel 6 descends to avoid the clamping component 4, so that the clamping component 4 can move smoothly along the first direction, realizing automatic loading and unloading.

[0027] The stock support assembly 3 includes a support base 31. A cylinder 32 is provided between the support base 31 and the V-shaped wheel 36. The telescopic movement of the cylinder 32 can drive the V-shaped wheel 36 to move up and down. The cylinder 32 is vertically arranged on the support base 31. A connecting seat 35 is provided at the upper end of the cylinder 32. The upper end of the cylinder 32 is the piston rod end of the cylinder 32. The V-shaped wheel 36 is rotatably arranged on the connecting seat 35. A plurality of guide rods 33 are connected to the lower end of the connecting seat 35. The guide rods 33 are vertically arranged. A plurality of guide cylinders 34 are provided on the support base 31. The guide rods 33 extend into the guide cylinders 34 and are in clearance fit with the guide cylinders 34. The cylinder 32 is connected to the controller.

[0028] In the present utility model, the piston rod of the cylinder 32 is controlled by the controller to extend and retract, driving the connecting seat 35 to move up and down, and driving the V-shaped wheel 36 to move up and down, so as to support the steel pipe and avoid the clamping assembly 4, making the axis of the steel pipe always coincide with the axis of the chuck. The guide cylinder 34 limits the guide rod 33 to move the guide rod 33 in the vertical direction, preventing the connecting seat 35 from tilting when the piston rod of the cylinder 32 extends and retracts to drive the connecting seat 35 to move up and down, affecting the support effect.

[0029] A moving seat 5 that moves in the first direction is provided on the truss 1. The moving seat 5 can be sleeved on the truss 1. The clamping assembly 4 includes a hydraulic center rest 41 and a hydraulic station 42. Both the hydraulic center rest 41 and the hydraulic station 42 are arranged on the moving seat 5. The hydraulic center rest 41 includes an oil cylinder. The oil cylinder and the hydraulic station 42 are connected by an oil pipe. The oil cylinder is connected to the controller. The hydraulic center rest 41 includes two clamping arms 411. The piston rod 412 of the oil cylinder is in sliding fit with the two clamping arms 411. The telescopic movement of the piston rod 412 of the oil cylinder drives the two clamping arms 411 to close and open. Rotatable rollers 413 are provided at the front ends of both clamping arms 411. A rotatable roller 413 is provided at the end of the piston rod 412 of the oil cylinder. When the hydraulic center rest 41 clamps the steel pipe, all three rollers 413 are in contact with the steel pipe. At this time, the centers of the three rollers 413 are located on the axis of the chuck.

[0030] A slide rail is provided on the truss 1. A slide seat is provided on the moving seat 5. The slide seat is slidably connected to the slide rail. A servo motor for driving the moving seat 5 to slide is provided on the truss 1. The servo motor is connected to the controller. A gear is provided at the output end of the servo motor. A rack is provided on the moving seat 5. The gear meshes with the rack. A monitoring sensor is provided on the clamping assembly 4. The monitoring sensor is connected to the controller. The controller is a PLC.

[0031] Specifically, the controller controls the operation of the servo motor to drive the clamping assembly 4 to move. The servo motor drives the gear to rotate, and the gear drives the rack to move in the first direction. The rack drives the moving seat 5, and then drives the clamping assembly 4 to move in the first direction. The controller controls the oil cylinder, and the piston rod 412 of the oil cylinder extends. The two clamping arms 411 approach each other until they clamp the steel pipe to be processed. The piston rod 412 of the oil cylinder retracts, and the two clamping arms 411 release the material. When the hydraulic center frame 41 clamps the steel pipe, all three rollers 413 are in contact with the steel pipe. At this time, the clamping center of the steel pipe by the hydraulic center frame 41 is collinear with the chuck center, that is, the centers of the three rollers 413 are located on the axis of the chuck, which can make the movement of the steel pipe smoother. The rollers 413 can make the hydraulic center frame 41 better clamp the steel pipe, center the steel pipe and avoid damage to the steel pipe. The monitoring sensor can monitor the length and position of the steel pipe. The PLC calculates the clamping position of the steel pipe according to the length of the steel pipe, and confirms the height of the V-shaped wheel 36 according to the position of the steel pipe. The monitoring sensor can monitor the position of the V-shaped wheel 6 in real time and transmit the signal to the PLC. When the monitoring sensor detects the V-shaped wheel 36, the PLC controls the piston rod of the cylinder 32 on the V-shaped wheel 6 to descend, so that the V-shaped wheel 36 descends to avoid interference with the hydraulic center frame 41. After the monitoring sensor has no signal, it controls the piston rod of the cylinder 32 to rise, and the V-shaped wheel 36 rises to continue supporting the steel pipe, thus realizing automatic loading and unloading.

[0032] Specific operation process

[0033] According to the diameter of the steel pipe, the PLC controls the piston rod of the cylinder 32 to extend upward, driving the connecting seat 35 to move upward, driving the V-shaped wheel 36 to move upward to support the steel pipe. At this time, the axis of the steel pipe is collinear with the axis of the chuck. The PLC calculates the clamping position of the steel pipe according to its length, starts the servo motor, the output end of the servo motor rotates, drives the gear to rotate, drives the rack to move in the first direction, drives the moving seat 5, and further drives the hydraulic center rest 41 to slide to the clamping position. Then start the oil cylinder on the hydraulic center rest 41, the piston rod 412 of the oil cylinder extends, and the two clamping arms 411 approach each other until the steel pipe to be processed is clamped. All three rollers 413 are in contact with the steel pipe, and the centers of the three rollers 413 are located on the axis of the chuck. Start the servo motor again. Driven by the servo motor, the hydraulic center rest 41 transports the steel pipe to the lathe 2. Start the oil cylinder on the hydraulic center rest 41, the piston rod 412 of the oil cylinder retracts, and the two clamping arms 411 release the steel pipe. The lathe 2 receives the signal sent by the controller and processes the steel pipe. After the processing is completed, the hydraulic center rest 41 receives the signal, and the oil cylinder controls the hydraulic center rest 41 to clamp the steel pipe. The servo motor rotates in reverse, driving the hydraulic center rest 41 to move away from the lathe 2 to output the steel pipe. During the movement of the hydraulic center rest 41, the monitoring sensor senses the V-shaped wheel 36 in real time. When the V-shaped wheel 36 is sensed, a signal is sent to the controller, and the controller controls the piston rod of the cylinder 32 to descend, driving the connecting seat to descend, driving the V-shaped wheel 36 to descend, so that the height of the V-shaped wheel 36 is lower than the height of the hydraulic center rest 41, and the V-shaped wheel 36 does not interfere with the hydraulic center rest. After the monitoring sensor has no signal, the piston rod of the cylinder 36 rises with a delay, driving the V-shaped wheel 36 to rise with a delay, completing the blanking process.
