Description

TECHNICAL FIELD

[0001] The utility model relates to laser cladding technical field especially relates to a laser cladding device. BACKGROUND

[0002] Laser cladding technology is a kind of special processing technology that coating material and substrate surface thin layer are irradiated and melted by high-energy laser beam, and after solidification, substrate surface and powder metal reach metallurgical bonding.Laser cladding has protective and repair functions for workpieces, can improve the performance of workpieces, repair dimensional errors and functional modification, etc.Laser cladding workbench is widely used in aerospace, automobile manufacturing, industrial manufacturing and medical devices, etc.For example, in the manufacturing industry such as shipbuilding, petroleum, mining, a large number of pipelines are needed, and the inner and outer walls of these pipelines will be worn to varying degrees during use, affecting their performance and service life, so increasing the wear resistance, corrosion resistance and other properties of the inner and outer walls of the pipeline is the key to solving this problem.However, pipelines are divided into straight pipelines and non-straight pipelines with straight and arc parts, and traditional methods only melt the straight pipelines, so melting non-straight pipelines is a problem to be solved.

[0038] In order to better explain the utility model, so as to facilitate understanding, the following will be combined with the drawings, through specific embodiment, the utility model is described in detail.

[0039] Embodiment 1:

[0040] Refer to Figures 1 to 10The embodiment provides a laser cladding device for cladding an L-shaped pipeline. Specifically, the laser cladding device comprises a workbench 1, a cladding mechanism 2 for cladding the pipeline, and a first linear moving mechanism 3, a second linear moving mechanism 4 and a rotating mechanism 5 installed on the workbench 1, as described below.

[0041] The first linear moving mechanism 3 in the embodiment can cooperate with the cladding mechanism 2 to drive the cladding mechanism 2 to move along a first linear track, the second linear moving mechanism 4 can cooperate with the cladding mechanism 2 to drive the cladding mechanism 2 to move along a second linear track, and the rotating mechanism 5 can cooperate with the cladding mechanism 2 to drive the cladding mechanism 2 to move along a circular arc track; the first linear track is connected with the second linear track through the circular arc track, and the first linear track and the second linear track are perpendicular to each other.

[0042] Specifically, the first linear track and the second linear track are linear, and the straight lines on which the first linear track and the second linear track are located are perpendicular to each other, so that the first linear track and the second linear track form an L-shaped track, i.e. the shape of an L-shaped track. The rotating mechanism 5 can move along a circular arc track, i.e. the first linear moving mechanism 3 drives the cladding mechanism 2 to move along the first linear track to the rotating mechanism 5, then the rotating mechanism 5 drives the cladding mechanism 2 to move along the circular arc track to the second linear moving mechanism 4, and finally the second linear moving mechanism 4 drives the cladding mechanism 2 to move along the second linear track to complete the cladding of the pipeline, so that the first linear moving mechanism 3, the rotating mechanism 5 and the second linear moving mechanism 4 can drive the cladding mechanism 2 to complete the cladding of the pipeline.

[0043] In summary, compared with the prior art, the laser cladding device can cladding the L-shaped pipeline without clamping jaws on the cladding path, so that the cladding speed is faster and the structure is simpler.

[0044] Further, the first linear moving mechanism 3 and the second linear moving mechanism 4 are fixedly installed on the workbench 1. The first linear moving mechanism 3 and the second linear moving mechanism 4 are fixedly connected with the workbench 1 by welding, screwing or clamping.

[0045] Further, the rotating mechanism 5 is rotatably installed on the workbench 1, and the rotating mechanism 5 is provided with a third motor 51 fixedly connected with the bottom of the workbench 1. The rotating mechanism 5 is rotated by the third motor 51, and the moving speed of the cladding mechanism 2 can be controlled by controlling the rotating speed of the third motor 51. The third motor 51 is fixedly connected with the workbench 1 by welding, clamping or bonding.

[0046] Further, the rotating assembly comprises a rotating body and a cooperating assembly 52; the cooperating assembly 52 is located at the rotating execution end of the rotating body, and the rotating shaft of the rotating body is located at the center of the arc-shaped portion of the pipe. The rotating assembly rotates by rotating the rotating body itself, thereby driving the cooperating assembly 52 to rotate. The rotating shaft of the rotating body is the rotation center of the rotating body, and the cooperating assembly 52 rotates around the rotation center. The rotating body is located at the center of the arc-shaped portion of the pipe, and thus the distance between the arc-shaped portion of the pipe and the rotation center is the radius of the arc-shaped portion of the pipe.

[0047] Further, the first linear moving mechanism 3 comprises a first fixed seat 31 and a first track assembly 32 which are fixedly connected with each other. The first fixed seat 31 is used for fixing the first end of the pipe, and the first track assembly 32 can cooperate with the cladding mechanism 2 to drive the cladding mechanism 2 to move from the first fixed seat 31 along the first linear track. The second linear moving mechanism 4 comprises a second fixed seat 41 and a second track assembly 42 which are fixedly connected with each other. The second fixed seat 41 is used for fixing the second end of the pipe, and the second track assembly 42 can cooperate with the cladding mechanism 2 to drive the cladding mechanism 2 to move from the connection position of the circular arc track and the second linear track along the second linear track. The first fixed seat 31 and the first track assembly 32 are fixedly connected by welding, bonding or screwing, and the second fixed seat 41 and the second track assembly 42 are fixedly connected in the same way as the first fixed seat 31 and the first track assembly 32. The first end of the pipe and the second end of the pipe are the starting end and the ending end of the pipe. Therefore, the moving direction of the cladding mechanism 2 is from the first end to the starting position of the circular arc track along the first linear moving track, then to the connection position of the circular arc track and the second linear moving track along the circular arc track, and finally to the second end along the second linear moving track from the connection position of the circular arc track and the second linear moving track.

[0048] Further, the first fixing seat 31 and the second fixing seat 41 each comprise a support frame 311, a connecting plate 312, a first connecting rod 313, a second connecting rod 314, a linear lifting assembly 315, a first arc-shaped clamping plate 316 and a second arc-shaped clamping plate 317; the support frame 311 is fixed on the workbench top 1, the first connecting rod 313 and the second connecting rod 314 are each rotationally installed on the support frame 311, one end of the first connecting rod 313 below the rotationally installed position thereof is inserted into a first movable space formed at a first end of the connecting plate 312, one end of the second connecting rod 314 below the rotationally installed position thereof is inserted into a second movable space formed at a second end of the connecting plate 312, one end of the first connecting rod 313 above the rotationally installed position thereof is fixedly connected with the first arc-shaped clamping plate 316, one end of the second connecting rod 314 above the rotationally installed position thereof is fixedly connected with the second arc-shaped clamping plate 317, the opening of the first arc-shaped clamping plate 316 is oppositely arranged with the opening of the second arc-shaped clamping plate 317, and the connecting plate 312 is connected with the support frame 311 through the linear lifting assembly 315; the first movable space and the second movable space each have a first guide surface and a second guide surface arranged in sequence from bottom to top; the linear lifting assembly 315 drives the support frame 311 to move upward, the part of the first connecting rod 313 inserted into the first movable space and the part of the second connecting rod 314 inserted into the second movable space abut against the first guide surface and move downward and outward along the first guide surface, thereby driving the first arc-shaped clamping plate 316 and the second arc-shaped clamping plate 317 to move closer to each other; the linear lifting assembly 315 drives the support frame 311 to move downward, the part of the first connecting rod 313 inserted into the first movable space and the part of the second connecting rod 314 inserted into the second movable space abut against the second guide surface and move upward and inward along the second guide surface, thereby driving the first arc-shaped clamping plate 316 and the second arc-shaped clamping plate 317 to move away from each other.

[0049] Specifically, the support frame 311 is configured as a fixed plate structure with an arc-shaped groove connected to the support plate in parallel with the workbench top 1, and the support plate and the fixed plate can be integrally formed, or can be connected by clamping or screwing, etc. The linear lifting assembly 315 is a structure capable of driving the connecting plate 312 to move in the upward and downward directions, so that the linear lifting assembly 315 can be a combination of a screw rod and a threaded cylinder, the top end of the screw rod is fixedly connected with the connecting plate 312, the bottom end of the screw rod is inserted into the light hole on the support frame 311, and the threaded cylinder abuts against the upper surface of the support frame 311, and the connecting plate 312 can be moved upward and downward by rotating the threaded cylinder on the screw rod; the linear lifting assembly 315 can also be a combination of a screw rod and a nut, and the principle is the same as above; the linear lifting assembly 315 can also drive the connecting plate 312 to move upward and downward by a hydraulic rod. The shapes of the first movable space and the second movable space are capsule-shaped, trapezoidal or parallelogram-shaped, etc. The first arc-shaped clamping plate 316 and the second arc-shaped clamping plate 317 can be combined to form a circle to clamp and fix the pipeline, the first movable space and the second movable space extend from the lower direction to the middle direction of the connecting plate 312, so that the direction extending to the middle of the connecting plate 312 is inside, and the direction extending to the two ends of the connecting plate 312 is outside, and the length between the first movable space and the second movable space in the connecting plate 312 is longer than the length between the rotating installation positions of the first connecting rod 313 and the second connecting rod 314, the first connecting rod 313 and the second connecting rod 314 respectively make circular motion, and drive the first connecting rod 313 and the second connecting rod 314 to rotate around the rotating installation positions as the connecting plate 312 moves upward and downward, so that when the connecting plate 312 moves upward, the first arc-shaped clamping plate 316 and the second arc-shaped clamping plate 317 move away from each other, and when the connecting plate 312 moves downward, the first arc-shaped clamping plate 316 and the second arc-shaped clamping plate 317 move away from each other. When the connecting plate 312 moves upward, the connecting portions of the first connecting rod 313 and the second connecting rod 314 move along the first guide surface from the top end to the bottom end in the first movable space and the second movable space. When the connecting plate 312 moves downward, the connecting portions of the first connecting rod 313 and the second connecting rod 314 move along the second guide surface from the bottom end to the top end in the first movable space and the second movable space.

[0050] Further, the first end of the screw rod rail 321 is fixedly connected with the support frame 311, the second end of the screw rod rail 321 is provided corresponding to the connection between the straight line part and the arc-shaped part of the pipeline, and the second end of the screw rod rail 321 allows the sliding bracket 21 to move into the pipeline arc-shaped part. The L-shaped pipeline has two straight line parts, so that when the sliding bracket 21 enters or leaves the screw rod rail 321, the screw rod rail 321 needs an opening end through which the sliding bracket 21 can enter or leave.

[0051] Further, the first track assembly 32 and the second track assembly 42 each comprise a screw rod track 321, screw rod pieces 322 and 323; the screw rod track 321 is fixedly connected with one end of the support frame 311, the screw rod piece 322 is rotationally arranged in the screw rod track 321, and the 323 drives the screw rod piece 322 to rotate; the cladding mechanism 2 comprises a sliding support 21, which is threadedly connected with the screw rod piece 322. By using the working principle of the screw rod, the sliding support 21 is provided with a threaded hole matched with the screw rod piece 322, so that when the screw rod piece 322 is connected with the sliding support 21, the rotary motion is converted into linear motion by the rotation of the screw rod piece 322, driving the sliding support 21 to move linearly. The screw rod piece 322 is arranged in the preset screw rod track 321, and the 323 can stably drive the rotation speed of the screw rod piece 322 to accurately control the sliding support 21 matched with the screw rod piece 322, thereby achieving better cladding effect on the surface of the pipeline. The screw rod track 321 is fixedly connected with the support frame 311 by screwing, bonding or clamping, etc. In this embodiment, the 323 is arranged in the accommodating cavity on the support frame 311.

[0052] Further, the cladding mechanism 2 further comprises: a fixed ring 22, which is fixedly connected with the sliding support 21 and is sleeved on the pipeline; a second motor 23, which is fixedly connected to the side of the fixed ring 22 away from the rotating mechanism 5, and a first gear 24 is fixedly sleeved on the output shaft of the second motor 23; a second gear 25, which is coaxially arranged with the fixed ring 22 and is rotationally connected to the fixed ring 22, and is engaged with the first gear 24; a cladding head piece 26, which is fixedly connected to the inside of the second gear 25 and can rotate with the second gear 25 to cladding the outer surface of the pipeline; and a clamping rod 27, which is fixedly connected to the side of the fixed ring 22 close to the rotating mechanism 5 and can form a clamping connection with the matching assembly 52.

[0053] Specifically, the fixed ring 22 is fixedly connected with the second motor 23 by welding, bonding or screwing, etc. The fixed ring 22 and the second motor 23 are non-rotating parts, while the first gear 24 is fixedly connected with the output shaft of the second motor 23 by interference connection, bonding or welding, etc. The first gear 24 rotates with the rotation of the second motor 23, the second gear 25 is engaged with the first gear 24, and the second gear 25 is rotationally connected with the fixed ring 22, so the first gear 24 and the second gear 25 are rotating parts. The cladding head piece 26 is fixedly connected with the second gear 25 by bonding, welding or clamping, etc. Thus, the cladding head piece 26 can rotate with the second gear 25 to uniformly cladding the surface of the pipeline. One end of the clamping rod 27 is fixedly connected with the side of the fixed ring 22 close to the rotating mechanism 5 by bonding, welding or clamping, etc., and the other end of the clamping rod 27 can form a clamping connection with the matching assembly 52, i.e. the rotating mechanism 5 drives the fixed ring 22 to pass through the arc-shaped part of the pipeline through the clamping rod 27.

[0054] Further, the matching assembly 52 comprises a connecting shaft 521, a hook 522 and two connecting blocks 523. The connecting blocks 523 are transversely provided with a notch, the hook 522 is located between the two connecting blocks 523, the abutting surface of the two connecting blocks 523 and the hook 522 extends upwardly and away from the hook 522 from bottom to top, the connecting shaft 521 is fixedly connected to the rotating mechanism 5 by penetrating one side of the two connecting blocks 523 and the hook 522, the connecting blocks 523 are fixedly connected to the connecting shaft 521, and the hook 522 is rotatably connected to the connecting shaft 521. When the fixing ring 22 moves from the linear portion of the pipeline to the arc-shaped portion, the clamping rod 27 abuts against the hook 522, and the hook 522 rotates to form clamping with the clamping rod 27. When the fixing ring 22 moves from the arc-shaped portion of the pipeline to the linear portion, the clamping rod 27 gradually inclines in the notch along with the movement of the fixing ring 22, and when the clamping rod 27 is parallel to the surface of the connecting blocks 523, the clamping rod 27 is separated from the matching assembly 52. The one side of the two connecting blocks 523 and the hook 522 is provided with a through hole, the diameter of the through hole of the two connecting blocks 523 is equivalent to the diameter of the connecting shaft 521, and the diameter of the through hole of the hook 522 is greater than the diameter of the connecting shaft 521. Therefore, the hook 522 can rotate on the connecting shaft 521, and the abutting surface of the connecting blocks 523 and the hook 522 extends upwardly and away from the hook 522 from bottom to top, that is, the width of the top end of the hook 522 is greater than the width of the bottom end of the hook 522. Therefore, the hook 522 is clamped between the two connecting blocks 523 and cannot continue to rotate downwardly.

[0055] Specifically, along with the movement of the cladding mechanism 2, when the cladding mechanism 2 moves to the end of the linear portion of the L-shaped pipeline, the clamping rod 27 abuts against the hook 522, and the abutting end of the hook 522 and the clamping rod 27 inclines downwardly and approaches the connecting shaft 521. Therefore, the clamping rod 27 can lift the hook 522, the cladding mechanism 2 continues to move, the hook 522 rotates, and the clamping rod 27 enters the inside of the hook 522 until the clamping rod 27 forms clamping with the hook 522. The clamping rod 27 rotates along with the rotation of the rotating mechanism 5, and the cladding mechanism 2 moves along the arc-shaped portion of the L-shaped pipeline. When the cladding mechanism 2 moves to the end of the arc-shaped portion of the L-shaped pipeline, the cladding mechanism 2 is connected to the second track assembly 42. Along with the continuous rotation of the rotating mechanism 5, the clamping rod 27 gradually forms an angle with the hook 522, and when the clamping rod 27 is parallel to the outer surface of the connecting blocks 523, the clamping rod 27 is separated from the hook 522.

[0056] Embodiment 2:

[0057] With reference to Figure 11 The difference between the present embodiment and embodiment 1 is that the shape of the pipeline is linear, and other structures are modified as appropriate, which will be described in detail below.
