The first and second traveling

mechanisms

500 and 600 have the same structure, and the first traveling mechanism 500 is described in detail herein as an example.

As shown in fig. 1, the first traveling mechanism 500 is disposed on the support base 400, and includes a power unit 510 and a transmission mechanism. The power unit 510 is fixed on the support 400 and disposed at or near an end of the linear guide 410, which may be an end of the linear guide 410 away from the pipe support 300 or an end of the linear guide 410 near the pipe support 300, and is selected according to actual requirements. The power unit 510 is used for providing power to drive the first striker 100 to move along the linear guide 410. In some embodiments, the power component 510 includes a motor, which may optionally be a servo motor. The servo motor is connected with the first stock stop 100 through a transmission mechanism, so as to drive the first stock stop 100 to move. The transmission mechanism may adopt a screw rod structure, that is, one end of the screw rod 520 is connected to the servo motor, and the screw rod 520 is engaged with the first material blocking mechanism 100. After the servo motor outputs power, the screw rod 520 is driven to rotate, and the screw rod 520 is meshed with the first material blocking mechanism 100, so that the first material blocking mechanism 100 slides along the linear guide rail 410. A speed reducer, an electromagnetic clutch gear, and the like may be provided between the screw 520 and the servo motor. In some embodiments, the power component 510 may be selected to be a hydraulic drive or other device capable of driving the first striker mechanism 100 to move.

As shown in fig. 1 and 2, the pipe supporting device 300 is used to support a pipe to be processed. The tube support device 300 includes a frame 330, a first support roller 310. The bottom of the bracket 330 is mounted on the supporting base 400, two parallel beams 320 are arranged on the top of the bracket 330, and the first supporting roller 310 is arranged on the beams 320. The first supporting rollers 310 may be sequentially spaced on the cross member 320. An adjusting mechanism for adjusting the height of the tube supporting unit 300 from the support base 400 may be further provided in the tube supporting unit 300, and for example, the height of the holder 330 may be adjusted by driving with a servo motor.

The first material stopping mechanism 100 and the second material stopping mechanism 200 have the same structure, and only the first material stopping mechanism 100 is taken as an example for detailed description.

As shown in fig. 1, 2 and 4, the first stock stop mechanism 100 includes a frame 110, a second supporting roller 120 disposed on the frame 110, and a stock stop 130. The frame 110 is disposed on the linear guide 410, and is engaged with the linear guide 410 to be slidable on the linear guide 410. The rack 110 is further provided with a slider 150 engaged with the screw 520, and when the screw 520 rotates, the slider 150 moves along the screw 520, thereby moving the rack 110 together. The second support roller 120 is used to support the tube after the first dam mechanism 100 approaches the tube to be processed. The second support roller 120 may be maintained at the same height as the first support roller 310 of the tube supporting device 300 and be positioned in the same line as the first support roller 310. The dam member 130 is disposed on the second backup roller 120 on a side facing away from the tube supporting device 300, and blocks an end of the tube to be processed. For example, after the tube is placed on the tube support device 300, the tube is not in the central position and is more biased to the side of the first stop mechanism 100; after the first material blocking mechanism 100 contacts with the pipe, the pipe moves along with the first material blocking mechanism 100 due to the blocking of the material blocking part 130 until the second material blocking structure contacts with and blocks the other end of the pipe. The dam member 130 may be a baffle vertically protruding from the frame 110. Keep off material part 130 and can also set up gasket 131 towards one side of second backup roller 120, can play the cushioning effect when keeping off the tip that material part 130 contacted the pipe, can also protect the tip of pipe simultaneously, avoid the tip of pipe and keep off direct contact between the material part 130 and cause the damage to the pipe.

The first stopper mechanism 100 may further include a lifting device to raise or lower the heights of the second backup roller 120 and the stopper member 130, so that the second backup roller 120 and the first backup roller 310 of the tube supporting device 300 can always maintain the same height.

The first stop mechanism 100 is further provided with a guide portion 140, the guide portion 140 is located on one side of the second backup roller 120 facing the tube supporting device 300, the guide portion 140 has a shape similar to that of the second backup roller 120, i.e. both are recessed towards the middle to form a tapered groove, and the groove bottom of the tapered groove formed on the guide portion 140 and the groove bottom of the middle of the second backup roller 120 are on the same straight line. When the first material blocking mechanism 100 moves to contact with the end of the pipe, the guide part 140 first contacts with the end of the pipe, and can guide the pipe to accurately enter the second supporting roller 120, and meanwhile, the guide part 140 can also play a role of auxiliary support.

Because the first material blocking mechanism 100 and the second material blocking mechanism 200 move towards the middle synchronously, the two mechanisms have the same movement stroke, and the distance between the two mechanisms and the end part of the corresponding pipe supporting device 300 after the two mechanisms reach the target position is equal, when the first material blocking mechanism 100 and the second material blocking mechanism 200 respectively contact and block the two ends of the pipe, the pipe can be well positioned in the middle position on the pipe supporting device 300, and then the centering operation of the pipe is completed. The process does not need manual participation, and automatic control can be realized through electrification in the whole process, so that the centering precision of the pipe is higher.

The running mechanism is driven by the servo motor, so that the rotating angle of the servo motor can be conveniently obtained, the length of the pipe to be processed can be automatically calculated and output by the system according to the rotating angle and the size parameters of the system, and the measurement precision is high.
