[0002] With the maturity of laser technology, the application of lasers in industry is becoming more and more extensive. Laser cutting has high dimensional accuracy, smooth and clean cut edges, no burrs, and extremely low material loss; the heat affected zone of laser cutting is very small, almost no thermal deformation, no oxidation, and high-quality and more consistent parts can be manufactured; the cutting efficiency is high, and mass production can be achieved. Therefore, laser cutting is widely used in the cutting of pipes.

[0003] In the prior art, a laser pipe cutting machine for cutting pipes generally includes a base with a guide rail provided at the top, a workbench slidably arranged on the guide rail, and a body for clamping pipes fixed on the workbench. The body drives the pipes to move by rotating and feeding and moving along the guide rail, so that the laser cutting head can cut the pipes. During the cutting process of the pipes, the axial direction of the pipes should be consistent with the moving direction of the pipes. Different types of laser cutting machines or the bodies for clamping pipes need to be replaced for processing different pipes. Limited by the workbench, when the body is fixed to the workbench through T-shaped blocks and pressing blocks, engineers need to perform a series of measurement and adjustment on the body to ensure that the pipes clamped by the body are consistent with the length direction of the guide rail.

[0041] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] An embodiment of the present invention provides a horizontal adjustment mechanism for a laser pipe cutting machine body, including a first housing 1, an auxiliary leveling component 2, a main leveling component 3, a stable leveling component 4 and a first base 5. Exemplarily, as Figure 1 shown.

[0043] One end of the first housing 1 is rotatably installed at one end of the first base 5; the first housing 1 is rotatably installed between two groups of the auxiliary leveling components 2; the two groups of the auxiliary leveling components 2 are fixedly installed on the first base 5 and are located on both sides of the first housing 1.

[0044] The main leveling component 3 is fixedly installed on the first base 5 and is in transmission connection with the first housing 1.

[0045] The stable leveling component 4 is fixedly installed inside the first housing 1.

[0046] The top plate of the first housing 1 is used for fixedly installing the body of the laser pipe cutting machine; the auxiliary leveling assembly 2 is used for leveling itself; the main leveling assembly 3 is used for leveling the first housing 1; the stable leveling assembly 4 is used for accelerating the leveling of the main leveling assembly 3.

[0047] The first housing 1 includes a top plate 11, side plates 12, a first rotating shaft 13 and a bottom plate 14. Exemplarily, as Figure 2 and Figure 3 shown.

[0048] The upper ends of the two groups of side plates 12 are fixedly connected to both ends of the top plate 11; the lower ends of the two groups of side plates 12 are fixedly connected to both ends of the bottom plate 14. A first guiding groove 121 is provided on the outer wall of one end of the side plate 12, and teeth are provided on the side wall of the first guiding groove 121; a clamping post 122 is provided on the outer wall of the other end of the side plate 12.

[0049] The first rotating shaft 13 penetrates through the two groups of side plates 12 and is rotatably installed at the center point of the side plates 12 through a first ball bearing. Two groups of first balance rods 131 are provided on the first rotating shaft 13, and the two groups of first balance rods 131 are centrosymmetric with the central axis of the first rotating shaft 13 as the center.

[0050] The first balance rods 131 are located between the two groups of side plates 12; the two groups of first balance rods 131 are fixedly connected through a second ball bearing; the two groups of first balance rods 131 can rotate with the central axis of the first rotating shaft 13 as the center; first counterweight blocks 132 are provided at the ends of the two groups of first balance rods 131 away from the first rotating shaft 13, making the two symmetric first balance rods 131 easier to balance.

[0051] Exemplarily, since the two groups of first balance rods 131 are the same, the two groups of first balance rods 131 will always remain balanced without external forces.

[0052] First laser rangefinders 142 are fixedly installed at both ends of the bottom plate 14; the first laser rangefinders 142 are located below the ends of the first balance rods 131; the first laser rangefinders 142 are used to measure the distance to the ends of the first balance rods 131. When the distances measured by the two groups of first laser rangefinders 142 to the ends of the first balance rods 131 are equal, the bottom plate 14 is in a horizontal state, the top plate 11 is in a horizontal state, and the body of the laser pipe cutting machine installed on the top plate 11 is also in a horizontal state. A group of first through holes 141 are respectively opened at both ends of the bottom plate 14.

[0053] A second guiding groove 51 is provided at the other end of the first base 5 close to the side plate 12, and the second guiding groove 51 is arc-shaped; the clamping post 122 is movably clamped in the second guiding groove 51. A third guiding groove 52 is also provided on the first base 5.

[0054] The auxiliary leveling assembly 2 includes a first air cylinder 21, a second housing 22, a first connecting plate 23, a second rotating shaft 24, and a second laser rangefinder 26. Exemplarily, as Figure 4 and Figure 5 shown.

[0055] One ends of the bodies of the two groups of first air cylinders 21 are fixedly installed on the first base 5; one ends of the output shafts of the first air cylinders 21 are respectively hinged to both ends of the bottom of the second housing 22.

[0056] The second rotating shaft 24 penetrates through the second housing 22, and the second rotating shaft 24 is rotatably installed at the center point of the second housing 22 through a third ball bearing. Two groups of second balance rods 25 are arranged on the second rotating shaft 24, and the two groups of second balance rods 25 are centrosymmetric with the central axis of the second rotating shaft 24 as the center.

[0057] The second balance rods 25 are located in the inner cavity of the second housing 22; the two groups of second balance rods 25 are fixedly connected through a fourth ball bearing, and the two groups of second balance rods 25 can rotate with the central axis of the second rotating shaft 24 as the center. Second counterweights 251 are also arranged at the ends of the two groups of second balance rods 25 far from the second rotating shaft 24, so that the two symmetric second balance rods 25 are easier to balance.

[0058] Two groups of second laser rangefinders 26 are further arranged on the bottom inner wall of the second housing 22, and the second laser rangefinders 26 are located directly below the second counterweights 251 of each group of second balance rods 25; the second laser rangefinders 26 are used to measure the distance from the bottom inner wall of the second housing 22 to the second counterweights 251.

[0059] The upper end of the first connecting plate 23 is fixedly connected to the first rotating shaft 13, and the lower end of the first connecting plate 23 is fixedly connected to the second rotating shaft 24.

[0060] Exemplarily, by measuring the distance to the second balance rod 25 with the second laser rangefinder 26, the telescopic length of the corresponding first air cylinder 21 is adjusted to keep the two groups of second balance rods 25 inside the second housing 22 in a balanced state. So that the first rotating shaft 13 is kept horizontal, which is beneficial to the leveling work.

[0061] The main leveling assembly 3 includes a first motor 31, a ball screw 32, a first moving block 33, a second motor 34, a guide rod 36, a second connecting plate 37, and a second moving block 38. Exemplarily, asFigure 6 as shown

[0062] One end of the body of the first motor 31 is fixedly installed on the second moving block 38; one end of the output shaft of the first motor 31 is drivingly installed with a ball screw 32; a guide rod 36 is arranged on one side of the first motor 31, and the lower end of the guide rod 36 is fixedly connected to the second moving block 38. The upper end of the guide rod 36 is fixedly installed on the second connecting plate 37; the upper end of the ball screw 32 is rotatably installed on the second connecting plate 37.

[0063] A third motor 39 is further arranged on the second moving block 38, and the second moving block 38 is movably clamped in the third guide groove 52; the third motor 39 is drivingly connected to the second moving block 38. When the third motor 39 is started, the second moving block 38 is allowed to move in the third guide groove 52 in a direction close to or away from the second guide groove 51.

[0064] The first moving block 33 is drivingly installed on the ball screw 32 and the guide rod 36; one end of the body of the first and second motor 34 is fixedly installed on one side of the first moving block 33 close to the side plate 12; one end of the output shaft of the second motor 34 is drivingly installed with a transmission gear 35; the transmission gear 35 meshes with the teeth on the first guide groove 121.

[0065] Preferably, the second motor 34 is a servo motor.

[0066] Exemplarily, when the second motor 34 is started, at this time the first moving block 33 and the second moving block 38 remain stationary, so that the transmission gear 35 rotates forward or backward to drive the side plate 12 to rotate about the first rotating shaft 13. When the transmission gear 35 rotates forward, the horizontal height of the end of the side plate 12 close to the second motor 34 rises. When the transmission gear 35 rotates backward, the horizontal height of the end of the side plate 12 close to the second motor 34 drops.

[0067] Exemplarily, when the second motor 34 is started, at this time the first moving block 33 and the second moving block 38 can both move. When the transmission gear 35 rotates forward, the horizontal height of the second motor 34 rises. When the first moving block 33 and the second moving block 38 are both immovable, the stroke of the end of the side plate 12 close to the second motor 34 dropping is increased.

[0068] Exemplarily, when the second motor 34 is started, at this time the first moving block 33 and the second moving block 38 can both move. When the transmission gear 35 rotates backward, the horizontal height of the second motor 34 drops. When the first moving block 33 and the second moving block 38 are both immovable, the stroke of the end of the side plate 12 close to the second motor 34 rising is increased.

[0069] The leveling component 4 includes an upper leveling part 41 and a lower leveling part 42; the first balance rod 131 is located between the upper leveling part 41 and the lower leveling part 42. Exemplarily, as Figure 7 , Figure 8 and Figure 9 shown.

[0070] The upper leveling part 41 includes a second cylinder 411, a third connecting plate 412, a first fixing block 413 and a second fixing block 416;

[0071] One end of the body of the second cylinder 411 is fixedly installed at the lower end of the top plate 11; one end of the output shaft of the second cylinder 411 is in transmission connection with the third connecting plate 412.

[0072] The end of the third connecting plate 412 away from the second cylinder 411 is fixedly connected to the first fixing block 413; several groups of card slots 4131 are opened on both sides of the first fixing block 413; several groups of the card slots 4131 are linearly arrayed in the direction close to the second cylinder 411.

[0073] The second fixing block 416 is elastically connected to the bottom end of the first fixing block 413 through a spring 415. The two sides of the second fixing block 416 are rotatably installed with clamping blocks 414 through torsion springs, and the clamping blocks 414 can be clamped in the card slots 4131.

[0074] A first sensor 417 is further arranged at the bottom end of the second fixing block 416. The first sensor 417 is in signal connection with the second cylinder 411 through a controller.

[0075] Exemplarily, when carrying the adjusting mechanism, the first balance rod 131 of the adjusting mechanism will be in a shaking state. In order to improve the leveling efficiency, it is necessary to first make the first balance rod 131 in a stable state.

[0076] Exemplarily, when an upward external force is applied to the end of the first balance rod 131 on the second fixing block 416, the first sensor 417 receives a pressure signal and the external force exceeds a preset value. At this time, the spring 415 contracts, and at the same time, the second fixing block 416 pushes the clamping block 414 to move towards the card slot 4131 closer to the second cylinder 411, and the clamping block 414 disengages from the current card slot 4131 and moves into the card slot 4131 closer to the second cylinder 411; at this time, the first sensor 417 still receives a pressure signal, and then the output shaft end of the second cylinder 411 is controlled to contract through the controller until the first sensor 417 no longer receives a pressure signal. At this time, the first balance rod 131 is not in contact with the first sensor 417. At this time, the two groups of first balance rods 131 are kept in balance.

[0077] When the second fixed block 416 is subjected to an upward external force at the end of the first balance rod 131 and the first sensor 417 receives a pressure signal that does not exceed the preset value, at this time, the spring 415 contracts, and the second fixed block 416 cannot transmit enough force to make the latch 414 disengage from the current card slot 4131. At this time, the first sensor 417 controls the contraction of one end of the output shaft of the second cylinder 411 through the controller until the first sensor 417 no longer receives a pressure signal, that is, the first balance rod 131 does not contact the first sensor 417, and at this time, the two groups of first balance rods 131 remain balanced.

[0078] The lower stable flat part 42 includes a third housing 421 and a third moving block 422;

[0079] The third housing 421 is fixedly installed on the bottom plate 14;

[0080] A first cavity 4211 is provided inside the third housing 421; an air inlet hole 4212 is provided on one side of the first cavity 4211 away from the first rotating shaft 13; a first solenoid valve 4213 is arranged above the air inlet hole 4212, and the first solenoid valve 4213 is used to control the opening and closing of the air inlet hole 4212. The air inlet hole 4212 is used to connect to an air inlet pump.

[0081] An air outlet hole 4214 is provided at the bottom end of the first cavity 4211, and a second solenoid valve 4215 is arranged below the air outlet hole 4214, and the second solenoid valve 4215 is used to control the opening and closing of the air outlet hole 4214; the air outlet hole 4214 is communicated with the first through hole 141.

[0082] The upper end of the third housing 421 is of an open structure; the third moving block 422 is movably clamped inside the third housing 421, and the connection part is hermetically arranged with the third housing 421. A second sensor 423 is arranged at the top end of the third moving block 422. The second sensor 423 is signal-connected to the first solenoid valve 4213 and the second solenoid valve 4215 through a controller.

[0083] The first balance rod 131 is located between the first sensor 417 and the second sensor 423.

[0084] Exemplarily, when the third moving block 422 is subjected to a downward external force at the end of the first balance rod 131, the second sensor 423 receives a pressure signal and the external force exceeds the preset value. At this time, the second sensor 423 controls the second solenoid valve 4215 to open the air outlet hole 4214 through the controller, so that the air in the first cavity 4211 flows out. At this time, the position of the third moving block 422 continues to drop smoothly until the second sensor 423 no longer receives a pressure signal. At this time, the first balance rod 131 does not contact the second sensor 423 and the two groups of first balance rods 131 remain in a balanced state.

[0085] When the third moving block 422 is not subjected to the downward external force at the end of the first balance bar 131, the second sensor 423 controls the first solenoid valve 4213 to open the air inlet hole 4212 through the controller, controls the second solenoid valve 4215 to close the air outlet hole, and makes the gas enter the first cavity 4211 through the air pump, so that the third moving block 422 rises smoothly until the second sensor 423 receives a pressure signal and is less than the preset value; at this time, the second sensor 423 controls the second solenoid valve 4215 to open the air outlet hole 4214 through the controller, so that the air in the first cavity 4211 flows out. At this time, the position of the third moving block 422 continues to drop smoothly until the second sensor 423 can no longer receive the pressure signal, that is, the two groups of first balance bars 131 are in a balanced state.

[0086] The working principle of the horizontal adjustment mechanism of a group of laser pipe cutting machine bodies proposed in the embodiments of the present invention is as follows:

[0087] First, measure the distance to the second balance bar 25 through the second laser rangefinder 26, and adjust the telescopic length of the corresponding first cylinder 21 to make the two groups of second balance bars 25 inside the second housing 22 in a balanced state, so that the first rotating shaft 13 is kept horizontal and the leveling accuracy is improved.

[0088] The upper leveling part 41 and the lower leveling part 42 can quickly make the swaying first balance bar 131 in a balanced state, improving the leveling speed.

[0089] After that, measure the distance to the first balance bar 131 through the first laser rangefinder 142, and adjust the rotation height of the side plate 12 to make the distances measured by the first laser rangefinder 142 to the two groups of first balance bars 131 equal, so that the top plate 11 of the horizontal adjustment mechanism is in a horizontal state, ensuring the leveling accuracy.

[0090] Based on the horizontal adjustment mechanism of a laser pipe cutting machine body proposed in the embodiments of the present invention, the embodiments of the present invention also propose an adjustment method for the horizontal adjustment mechanism of a laser pipe cutting machine body, including the following steps:

[0091] Control the auxiliary leveling component to make both ends of the first rotating shaft in a horizontal state;

[0092] Make the two groups of first balance bars in a balanced state through the upper leveling part and the lower leveling part;

[0093] Rotate the side plate through the main leveling component to make the distances from the two groups of first laser rangefinders to the ends of the first balance bar equal, and the leveling is completed.

[0094] Specifically, first, measure the distance to the second balance rod through the second laser rangefinder, and adjust the telescopic length of the corresponding first cylinder to keep the two groups of second balance rods inside the second housing in a balanced state, so that the first rotating shaft is kept horizontal, which is beneficial to the leveling work.
