First, the clamping mechanism is operated to clamp the pipe, and then the measuring component is manually operated on the inner wall and the outer wall of the pipe, and then the measurement is performed. Manual operation is required, which is not convenient enough. Summary of the invention

[0006] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0008] Specifically, the driving device includes a plurality of limit rods fixed on the base, a first rack fixed on the limit rod, a plurality of first locking seats slidably arranged on the limit rod, a movable ring arranged on the first locking seat and meshing with the threaded rod, a first connecting rod with one end rotatably arranged on the first locking seat and the other end rotatably arranged on the inner moving rod, and a second connecting rod with one end rotatably arranged on the fixing ring and the other end fixedly arranged on the inner moving rod; the first connecting rod and the second connecting rod are cross-rotatably arranged.

[0009] Specifically, the first locking device includes a plurality of third springs fixed on the movable ring, a first limit head fixed on the third spring, a first limit groove fixed on the first locking seat, a first push block slidably arranged on the first locking seat, a first locking block symmetrically slidably arranged on the first push block and in contact with the first push block, and a fourth spring with one end fixed on the first push block and the other end fixed on the first locking seat.

[0010] Specifically, the first unlocking device includes a plurality of first sliders slidably arranged on the inner moving rod, a first protrusion fixed on the first slider, a plurality of second sliders slidably arranged on the inner moving rod, a second protrusion fixed on the second slider, a first floating block slidably arranged on the outer moving rod, a fifth spring with one end fixed on the first floating block and the other end fixed on the inner moving rod, a plurality of first grooves fixed on the first floating block and in contact with the first protrusion and the second protrusion, a second locking block slidably arranged on the first locking seat, a first gear rotatably arranged on the first locking seat, a second floating block slidably arranged on the first locking seat, and a traction rope with one end fixed on the first floating block and the other end fixed on the second floating block.

[0011] Specifically, the second locking device includes a second rack fixed on the second slide groove, a plurality of sixth springs with one end fixed on the outer wall clamping head and the other end fixed on the outer moving rod, a seventh slide groove symmetrically fixed on the outer moving rod, a third locking block slidably arranged on the seventh slide groove, a plurality of seventh springs with one end fixed on the third locking block and the other end fixed on the outer moving rod, a third connecting rod fixed on the third locking block on one side, and a fourth locking block fixed on the third connecting rod.

[0012] Specifically, the linkage assembly includes a second gear rotatably arranged on the base, a third gear rotatably arranged on the base, a first chain sleeved on the second gear and the third gear, a fourth gear rotatably arranged on the base and meshing with the third gear, a fifth gear rotatably arranged on the base and meshing with the fourth gear, a sixth gear rotatably arranged on the base, a second chain sleeved on the fifth gear and the sixth gear, a seventh gear rotatably arranged on the base, and a third chain sleeved on the sixth gear and the seventh gear.

[0013] Specifically, the laser cutting mechanism includes a plurality of first electric telescopic rods fixed on a base, an electric slide rail fixed on the electric telescopic rod, a base slidably arranged on the electric slide rail, a second electric telescopic rod fixed on the base, a laser cutting head fixed on the second electric telescopic rod, a plurality of third electric telescopic rods fixed on the base, and an air pump fixed on the base.

[0014] The beneficial effects of the present invention are: (1) When in use, the pipe is placed vertically on the base, and the first clamping mechanism and the second clamping mechanism clamp the pipe from the top and bottom respectively. Compared with the existing clamping method, the clamping method of the present invention avoids the problem of rotation and bending of the pipe due to its own weight during cutting, which leads to cutting misalignment, thereby improving the cutting quality.

[0015] (2) In the initial state, each inner moving rod is driven by the moving ring, and each inner moving rod moves synchronously. When the axis of the circular pipe is not collinear with the axis of the base, the inner wall clamping head on one side will first contact the inner wall of the circular pipe and drive the pipe to move. When each inner wall clamping head is in contact with the inner wall, that is, the axis of the circular pipe is collinear with the axis of the base, the function of calibrating the center is realized. There is no need to manually calibrate the center during use, which is easy to use.

[0016] (3) When clamping a pipe with a smaller diameter, the inner moving rod can move a shorter distance to make the inner wall clamping head completely fit, so that the first locking block is fixed. If the outer moving rod and the inner moving rod move the same distance, the inner wall clamping head will have completed the clamping, while the outer wall clamping head has not yet contacted the outer wall of the pipe. Therefore, the diameter of the third gear is much larger than that of the other gears, so that the sliding distance of the outer moving rod can be much larger than that of the inner moving rod. Even when clamping a pipe with a smaller diameter, the inner wall clamping head and the outer wall clamping head can completely fit the inner and outer walls of the pipe; when clamping a pipe with a larger diameter, the outer wall clamping head The holding head first contacts the outer wall of the pipe, and after pushing the pipe to be calibrated and centered, the sixth spring is compressed, and the outer wall clamping head pushes the third locking block to slide to both sides, so that the teeth on the third locking block engage with the second rack, to complete the clamping and fixation of the outer wall. A third connecting rod is provided on the third locking block on one side, so the third locking block will drive the third connecting rod to move when it moves, and then drive the fourth locking block to disengage from the third chain to complete the unlocking. At this time, the inner moving rod continues to move without driving the outer moving rod to move, and can continue to move to clamp the inner wall of the pipe; it can clamp pipes of different diameters and has good versatility.

[0017] (4) When the diameter of the clamped pipe is large, the outer wall clamping head will first contact the outer wall of the pipe, pushing the pipe for calibration and centering. When the diameter of the clamped pipe is small, the inner wall clamping head will first contact the outer wall of the pipe, pushing the pipe for calibration and centering. Therefore, the second clamping mechanism can calibrate, center and clamp circular pipes, rectangular pipes and rectangular cylinders of different diameters, and has excellent versatility and applicability.

[0018] (4) The inner wall clamping assembly, the outer wall clamping assembly and the linkage assembly have extremely strong linkage. During the sliding process of the inner moving rod, the first locking block and the moving ring are unlocked, the first locking block is fixed, the inner wall of the pipe is clamped, the outer wall of the pipe is clamped, the outer moving rod is unlocked and fixed, and the pipe wall thickness is measured.

A second spring 770 having one end fixed on the clamping plate and the other end fixed on the inner moving rod; the inner moving rod can slide on the second slide groove and the third slide groove; the driving device cooperates with the motor to drive the inner moving rod to move; the inner wall clamping head can slide on the fourth slide groove, the inner wall clamping head contacts the inner wall of the pipe, the cross section of the contact part is semicircular, and the inner wall clamping head can clamp the pipe when it moves outward with the inner moving rod; the clamping plate can slide on the fifth slide groove, the clamping plate is a flat plate, and the clamping plate can clamp and cut the rectangular column when it moves toward the center with the inner moving rod, and has good versatility; The outer wall clamping assembly includes an outer moving rod 781 slidably arranged on the second slide groove and the third slide groove, a sixth slide groove 782 fixedly arranged on the outer moving rod, an outer wall clamping head 783 slidably arranged on the sixth slide groove, and a second locking device 784 fixedly arranged on the outer moving rod; the outer moving rod can slide on the second slide groove and the third slide groove, and is initially located at one end of the second slide groove and the third slide groove. When the inner moving rod moves outward, the inner moving rod is driven to move inward through the linkage assembly, and the pipe wall is clamped from the inside and the outside to improve the clamping effect; The detection component is fixedly mounted on the distance sensor 702 on the outer moving rod and the inner moving rod; the distance sensor is used to detect the thickness of the pipe wall. The distance sensor moves with the outer moving rod and the inner moving rod, and detects the thickness of the pipe wall after the outer moving rod and the inner moving rod are fully supported, without the need for manual operation.

[0028] Specifically, the driving device includes a plurality of limit rods 7721 fixed on the base, a first rack 7722 fixed on the limit rod, a plurality of first locking seats 7723 slidably arranged on the limit rod, a moving ring 7724 arranged on the first locking seat and meshing with the threaded rod, a first connecting rod 7725 with one end rotatably arranged on the first locking seat and the other end rotatably arranged on the inner moving rod, and a second connecting rod 7726 with one end rotatably arranged on the fixing ring and the other end fixedly arranged on the inner moving rod; the first connecting rod and the second connecting rod are cross-rotated; the limit rods are symmetrically arranged on both sides of the second slide groove and the third slide groove, corresponding to the second slide groove and the third slide groove one by one; the first locking seats are arranged around the moving ring, and the number corresponds to the inner moving rod one by one; the moving The inner wall of the ring is provided with a thread, which engages with the threaded column; in the initial state, the first locking device connects the movable ring and each first locking seat together. When the motor is working, it drives the threaded column to rotate. Since the movable ring and the first locking seat are connected together to form a whole at this time, the limit rod limits the first locking seat. Therefore, when the threaded rod rotates, the movable ring and the first locking seat can only move upward in the vertical direction. When the first locking seat moves upward, it pushes one end of the first connecting rod to move upward. Since the first connecting rod and the second connecting rod are rotated and cross-arranged, the lengths of the first connecting rod and the second connecting rod are fixed. Therefore, the first connecting rod and the second connecting rod will push the inner moving rod to move outward on the second slide groove and the third slide groove, that is, drive the inner wall clamping head to gradually approach and clamp the inner wall of the pipe.

[0029] Specifically, the first locking device includes a plurality of third springs 7731 fixed on the moving ring, a first limiting head 7732 fixed on the third spring, a first limiting groove 7733 fixed on the first locking seat, a first push block 7734 slidably arranged on the first locking seat, a first locking block 7735 symmetrically slidably arranged on the first push block and in contact with the first push block, and a fourth spring 7736 with one end fixed on the first push block and the other end fixed on the first locking seat; a tooth is provided on a side of the first locking block in contact with the first rack; the third The spring coefficient is greater than the spring coefficient of the fourth spring, that is, the third spring is harder than the fourth spring; in the initial state, the third spring pushes the first limit head into the first limit groove. Since the third spring is harder than the fourth spring, it will push the first push block to move, and the fourth spring is squeezed. The inclined surface on the first push block will push the first locking block to move inward and disengage from the first rack, but it is still located on the limit rod. Therefore, the limit rod can limit the first locking block, and the first locking block can slide on the limit rod, that is, the first locking seat and the movable ring can slide along the limit rod.

[0030] Specifically, the first unlocking device includes a plurality of first sliders 7741 slidably arranged on the inner moving rod, a first protrusion 7742 fixedly arranged on the first slider, a plurality of second sliders 7743 slidably arranged on the inner moving rod, a second protrusion 7744 fixedly arranged on the second slider, a first floating block 7745 slidably arranged on the outer moving rod, a fifth spring 7746 having one end fixedly arranged on the first floating block and the other end fixedly arranged on the inner moving rod, a plurality of first grooves 7747 fixedly arranged on the first floating block and contacting the first protrusion and the second protrusion, a second locking block 7748 slidably arranged on the first locking seat, a first gear 7749 rotatably arranged on the first locking seat, a second floating block 7740 slidably arranged on the first locking seat, a fifth spring 7746 having one end fixedly arranged on the first floating block and the other end fixedly arranged on the inner moving rod, A traction rope 77411 is fixed on the first floating block and the other end is fixed on the second floating block; the second floating block is provided with teeth that mesh with the first gear; the second locking block is provided with teeth that mesh with the first gear; the traction rope has no elasticity and is of fixed length; in the initial state, the second locking block is partially inserted into the moving ring and cooperates with the first limit head to connect the first locking seat and the moving ring together; since the rotation of the threaded column drives the moving ring to move upward, and then pushes the inner moving rod to move, a certain thread pitch of the threaded column can be set so that the distance the moving ring is driven to rise by each rotation of the threaded column is equal to the distance the inner moving rod is moved; since the distance the moving ring rises is equal to the distance the inner moving rod is moved, the length of the traction rope remains unchanged and is in a taut state;In the initial state, each inner moving rod is driven by the moving ring, and each inner moving rod moves synchronously. When the axis of the circular pipe is not collinear with the axis of the base, the inner wall clamping head on one side will first contact the inner wall of the circular pipe and drive the pipe to move. When each inner wall clamping head contacts the inner wall, that is, the axis of the circular pipe is collinear with the axis of the base, the function of calibrating the center is realized. When clamping a pipe with a rectangular cross-section, due to the different side lengths of the rectangle, one pair of inner wall clamping heads will contact the inner wall earlier than the other pair of inner wall clamping heads. In the process of movement of the inner moving rod, the first spring corresponding to the inner wall clamping head that contacts the inner wall first will be squeezed, and the inner wall clamping head will slide on the fourth slide groove and squeeze the first slider to move the first slider, and the first protrusion will squeeze the first floating block to move the first floating block upward, and the fifth spring will be compressed. Since the length of the traction rope is fixed and inelastic, the upward movement of the first floating block will cause the traction rope to drive the second floating block to move upward, and the second floating block drives the first gear to move, and the first gear drives the second locking block to move and disengage from the moving ring. At this time, the threaded column continues to drive the moving ring to rise. Due to the lack of locking of the second locking block, the first locking seat will squeeze the first limiting head, so that the third spring is squeezed, and then the first limiting groove will be out of contact with the first limiting head. At this time, the fourth spring will reset, push the first push block to move outward, and the first push block part will be pushed into the first limiting groove. The inclined surface on the first push block will push the first locking block to move to both sides, and the teeth on the first locking block will engage with the first rack, that is, the first locking seat is fixed on the limiting rod through the first locking block, thereby achieving clamping and fixing of the inner wall of the pipeline. At this time, the moving ring can continue to move upward, driving the remaining first locking seats to move upward, and then driving the remaining inner moving rods to slide and clamp the remaining inner walls; similarly, when clamping the rectangular column, the clamping plate can also calibrate and center the rectangular column. When one pair of clamping plates contacts the rectangular column before the other pair of clamping plates, the second protrusion will also push the first floating block to move, thereby achieving the disengagement of the first locking seat from the moving ring and the fixing of the first locking seat, that is, achieving the clamping and fixing of the rectangular column. ;

[0031] Specifically, the second locking device includes a second rack 7841 fixed on the second slide groove, a plurality of sixth springs 7842 with one end fixed on the outer wall clamping head and the other end fixed on the outer moving rod, a seventh slide groove 7843 symmetrically fixed on the outer moving rod, a third locking block 7844 slidably arranged on the seventh slide groove, a plurality of seventh springs 7845 with one end fixed on the third locking block and the other end fixed on the outer moving rod, a third connecting rod 7846 fixed on the third locking block on one side, and a fourth locking block 7847 fixed on the third connecting rod; the third locking block is provided with an inclined surface, the inclined surface contacts the outer wall clamping head, and the portion of the third locking block contacting the second rack is provided with teeth; the outer moving rod can be in the second slide groove When the outer moving rod moves, it will drive the outer wall clamping head to move together, and the outer wall clamping head will contact the outer wall of the pipe. The sixth spring is compressed, and the outer wall clamping head pushes the third locking block to slide to both sides, so that the teeth on the third locking block are engaged with the second rack, thereby completing the clamping and fixation of the outer wall. When the diameter of the clamped pipe is large, the outer wall clamping head will first contact the outer wall of the pipe, and push the pipe to be calibrated and centered. When the diameter of the clamped pipe is small, the inner wall clamping head will first contact the outer wall of the pipe, and push the pipe to be calibrated and centered. Therefore, the second clamping mechanism can calibrate, center and clamp circular pipes, rectangular pipes and rectangular cylinders of different diameters, and has excellent versatility and applicability.

[0032] Specifically, the linkage assembly includes a second gear 791 rotatably arranged on the base, a third gear 792 rotatably arranged on the base, a first chain 793 sleeved on the second gear and the third gear, a fourth gear 794 rotatably arranged on the base and meshing with the third gear, a fifth gear 795 rotatably arranged on the base and meshing with the fourth gear, a sixth gear 796 rotatably arranged on the base, a second chain 797 sleeved on the fifth gear and the sixth gear, a seventh gear 798 rotatably arranged on the base, and a third chain 799 sleeved on the sixth gear and the seventh gear; the inner moving rod is fixedly connected to the first chain; the third locking block on the outer moving rod is inserted into the third chain in the initial state The third gear is composed of a large gear and a small gear, and the diameter of the small gear is the same as that of the second gear; the first chain is mounted on the small gear and the second gear; the fourth gear is a gear column, which meshes with the large gear on the third gear; the fifth gear is composed of a small gear and a large gear, and the large gear meshes with the fourth gear; the sixth gear is a gear column, and the second chain is mounted on the small gears of the sixth gear and the fifth gear; the third chain is mounted on the sixth gear and the seventh gear; when the inner moving rod moves, it will drive the first chain to move, the first chain drives the second gear and the third gear to rotate, the third gear drives the fourth gear to rotate, the fourth gear drives the fifth gear to rotate, and the fifth gear The wheel drives the sixth rack to rotate through the second chain, and the rotation of the sixth gear will drive the third chain to move, and then drive the outer moving rod to slide, and because the diameter of the third gear is much larger than the other gears, the movement speed of the third chain will be greater than the first chain, that is, the sliding distance of the outer moving rod will be much greater than that of the inner moving rod; when clamping a pipe with a smaller diameter, the inner moving rod can move a shorter distance to make the inner wall clamping head completely fit, so that the first locking block is fixed. If the outer moving rod and the inner moving rod move the same distance, the inner wall clamping head will have completed clamping, while the outer wall clamping head has not yet contacted the outer wall of the pipe. Therefore, the diameter of the third gear is much larger than that of the other gears, which can make the sliding distance of the outer moving rod much greater than that of the inner moving rod The movable rod can make the inner wall clamping head and the outer wall clamping head completely fit the inner wall and outer wall of the pipe even when clamping a pipe with a smaller diameter; when clamping a pipe with a larger diameter, the outer wall clamping head first contacts the outer wall of the pipe, and after pushing the pipe to be calibrated and centered, the sixth spring is compressed, and the outer wall clamping head pushes the third locking block to slide to both sides, so that the teeth on the third locking block engage with the second rack to complete the clamping and fixation of the outer wall. A third connecting rod is provided on the third locking block on one side, so the third locking block will drive the third connecting rod to move when it moves, and then drive the fourth locking block to disengage from the third chain to complete the unlocking. At this time, the continued movement of the inner moving rod will not drive the outer moving rod to move, and the inner wall of the pipe can continue to be clamped.

[0033] Specifically, the laser cutting mechanism includes a plurality of first electric telescopic rods 81 fixed on the base, an electric slide rail 82 fixed on the electric telescopic rod, a base 83 slidably arranged on the electric slide rail, a second electric telescopic rod 84 fixed on the base, a laser cutting head 85 fixed on the second electric telescopic rod, a plurality of third electric telescopic rods 86 fixed on the base, and an air pump 87 fixed on the base; the first electric telescopic rod can adjust the position of the laser cutting head; the second electric telescopic rod can adjust the position of the air pump; the base can slide on the electric slide rail to drive the laser cutting head to complete cutting; the air pump is used to spray auxiliary gas for cooling and protection, which is the existing technology.
