[0003] When the existing high-speed laser cladding equipment for the outer surface of pipe fittings is in use, it is necessary to first clamp and position the pipe fitting to ensure the processing quality of the surface coating of the pipe fitting. In the prior art, a three-jaw chuck is mostly used to clamp one end of the pipe fitting, and then another clamping component is adjusted to hold the other end of the pipe fitting, so as to clamp and position the pipe fitting. When replacing pipe fittings of different specifications for laser cladding, it is necessary to adjust the position of the fixture, which increases the complexity of the operation. Since the three-jaw chuck needs to adjust the clamping position according to the outer diameter of the pipe fitting, the fixture needs to be frequently adjusted for the processing of pipe fittings of different specifications, resulting in low efficiency. Especially in the case of large differences in the sizes of pipe fittings, the consumption of time increases, thus affecting the efficiency of laser cladding on the outer surface of pipe fittings.

[0017] Compared with the prior art, the present invention provides a high-speed laser cladding device for the outer surface of a pipe fitting, and has the following beneficial effects:
[0018] 1. The high-speed laser cladding equipment for the outer surface of the pipe fitting can, by means of the first clamping plate, the second clamping plate, the arc plate, the transmission gear, the first rack plate, the second rack plate and the fixing column, drive the first rack plate and the second rack plate to move together through the transmission of the transmission gear when adjusting the up-and-down movement of the fixing column, so as to be able to adjust the distance between the first clamping plate and the arc plate, and can adapt to pipe fittings with different diameters for clamping and positioning. During actual use, only need to place the pipe fitting in the arc-shaped depression on the upper surface of the mounting plate, drive the first sprocket to rotate by the first motor, the two vertical plates move closer to each other, and the arc plate drives the inclined plate to adaptively fit the surface of the pipe fitting through the torsion spring to ensure the stable clamping of pipe fittings with different diameters. Then, the arc plate and the first clamping plate can move closer to each other to clamp and position the pipe fitting. When replacing pipe fittings of different specifications for surface laser cladding processing, there is no need to stop the machine for complex adjustment, and the next laser cladding processing can be quickly started, thus being able to improve the efficiency of the laser cladding processing on the outer surface of the pipe fitting.
[0019] 2. The high-speed laser cladding equipment for the outer surface of the pipe fitting can, by means of the connecting spring, the rotating block, the convex block, the groove, the cylinder and the first rectangular column, utilize the elastic force of the connecting spring. When adjusting the two vertical plates to move closer to each other, due to the frictional force between the first rectangular column and the inner wall of the cylinder, the convex block and the groove are separated, and the disc and the first rectangular column are pulled by the connecting spring. Whenever the deformation amount of the connecting spring increases, the reaction force generated by its deformation also increases, pulling the first rectangular column to move together with the vertical plate, that is, when the vertical plate is moving, the convex block and the groove are in a separated state. After the position of the vertical plate is adjusted, under the action of the elastic force of the connecting spring, the convex block and the groove can cooperate again. Therefore, when replacing pipe fittings of different specifications for laser cladding processing, the pipe fitting can be initially placed and positioned first, and then clamped, so as to ensure the stable clamping and positioning of pipe fittings of different specifications.
[0020] 3. During the process of the third rectangular column moving downward with the first clamping plate, due to the connection of the two L-shaped columns, it can drive the cladding mechanism to move downward together, that is, before the laser cladding processing of the pipe fitting, during the clamping process, it can simultaneously adjust the laser cladding head to approach the surface of the pipe fitting, and when replacing pipe fittings of different specifications for laser cladding processing, the distance between the laser cladding head in the cladding mechanism and the pipe fitting can be made consistent, while further improving the laser cladding efficiency and ensuring the quality of the laser cladding processing of the pipe fitting.

The walls of both mounting grooves 12 are symmetrically slidably connected with mounting blocks 2. A vertical plate 3 is fixedly connected above the two mounting blocks 2. A first adjusting mechanism 4 for adjusting the movement of the two vertical plates 3 is arranged in the plurality of mounting blocks 2. A vertical groove 5 is opened in the middle of the surface of the vertical plate 3. A clamping mechanism 6 for clamping and positioning pipe fittings of different specifications is arranged on the wall of the vertical groove 5. A second adjusting mechanism 7 for adjusting the rotation of pipe fittings of different specifications is arranged at the tops of the two vertical plates 3;
[0034] The clamping mechanism 6 includes a transmission gear 61 rotatably connected to the wall of the vertical groove 5. The outer side of the transmission gear 61 is meshed with a first rack plate 62 and a second rack plate 63. A first clamping plate 64 is fixedly connected to the surface of the first rack plate 62. A fixing column 65 is fixedly connected to the surface of the second rack plate 63 away from the first rack plate 62. Column grooves 66 are symmetrically opened on the surface of the fixing column 65. A first T-shaped column 67 is slidably connected to the wall of the column groove 66. A first spring 68 is sleeved on the outer side of the first T-shaped column 67. The lower ends of the two first T-shaped columns 67 are fixedly connected with a connecting block 69. A second clamping plate 610 is fixedly connected to the surface of the connecting block 69. A first gear 611 is meshed with one side surface of the fixing column 65;
[0035] The second adjusting mechanism 7 includes a worm gear 71 rotatably connected to the top of the vertical plate 3. A worm 72 is meshed and connected to the outside of the worm gear 71. One end of the worm 72 is fixedly connected to a third gear 73. A second gear 74 is meshed and connected below the third gear 73. The second gear 74 is meshed and connected to the first gear 611. One end of the other worm 72 is fixedly connected to a movable sleeve 75. The other end of the other worm 72 is fixedly connected to a second rectangular column 76. The second rectangular column 76 is slidably inserted into the movable sleeve 75. A third rectangular column 77 is slidably connected inside the worm gear 71. The lower end of the third rectangular column 77 is fixedly connected to a first bevel gear 78. A second bevel gear 79 is meshed and connected below the first bevel gear 78. An adjusting wheel 710 is fixedly connected to the surface of the second bevel gear 79. The adjusting wheel 710 is rotatably connected to the first clamping plate 64. A sliding key groove is provided inside the worm gear 71. The third rectangular column 77 is slidably connected to the worm gear 71 through a sliding key; An L-shaped column is rotatably connected to the surface of the third rectangular column 77 below the worm gear 71. Both L-shaped columns are slidably inserted into the cladding mechanism 14;
[0036] It should be noted that a plurality of screw holes are provided on the surface of the first rack plate 62. The first rack plate 62 and the first clamping plate 64 are fixed by bolts, and the up and down positions of the first clamping plate 64 can be adjusted according to the diameter and length of the actually clamped pipe fitting;
[0037] It should be noted that when replacing pipe fittings of different specifications for surface laser cladding processing, only need to place the pipe fitting in the arc-shaped depression on the upper surface of the mounting plate 1. The first motor 612 drives the first sprocket 616 to rotate, and the two vertical plates 3 approach each other. Both arc-shaped plates 9 can contact the two ends of the pipe fitting, and can clamp pipe fittings of different specifications. Then, the second clamping plate 610 and the arc-shaped plate 9 can approach each other with the first clamping plate 64 to clamp and position the pipe fitting. After clamping and positioning the pipe fitting, the outer sides of both adjusting wheels 710 can contact the surface of the pipe fitting. A rubber ring can be sleeved on the surface edge of the adjusting wheel 710 to increase the friction force, so that the pipe fitting can rotate. The second gear 74 rotates as the first gear 611 rotates, and the third gear 73 rotates as the second gear 74 rotates. The second rectangular column 76 and the movable sleeve 75 cooperate to enable the two worm gears 72 to rotate simultaneously. The rotation of the worm gear 72 drives the worm wheel 71 to rotate, and then drives the third rectangular column 77 to rotate. The third rectangular column 77 can move relative to the worm wheel 71. When adjusting the first clamping plate 64 and the second clamping plate 610 to approach each other, it will not affect the transmission. The first bevel gear 78 rotates together with the third rectangular column 77, and then drives the second bevel gear 79 to rotate, and then drives the adjusting wheel 710 to rotate. The rotation of the two adjusting wheels 710 can drive the pipe fitting to rotate. The rubber ring can be in close contact with the surface of the pipe fitting. Then, the slider can move relative to the electric slide rail 13 to drive the cladding mechanism 14 to perform laser cladding processing on the surface of the pipe fitting. When replacing pipe fittings of different specifications for surface laser cladding processing, there is no need to stop the machine for complex adjustment, and the next laser cladding processing can be quickly started, so as to improve the efficiency of surface laser cladding processing of pipe fittings;
[0038] It should be noted that during the process of the third rectangular column 77 moving downward with the first clamping plate 64, due to the connection of the two L-shaped columns, it can drive the cladding mechanism 14 to move downward together. That is, during the clamping process before laser cladding processing of the pipe fitting, it can simultaneously adjust the laser cladding head to approach the surface of the pipe fitting, and when replacing pipe fittings of different specifications for laser cladding processing, the distance between the laser cladding head in the cladding mechanism 14 and the pipe fitting can be made consistent, while further improving the laser cladding efficiency and ensuring the quality of laser cladding processing of the pipe fitting;
[0039] It should be noted that multiple balls can be arranged on the surface of the arc-shaped plate 9 to reduce the frictional resistance of the rotation of the pipe fitting. The surfaces of the first clamping plate 64 and the arc-shaped plate 9 are both arc-shaped. According to the specifications of the pipe fitting that needs to be subjected to surface laser cladding actually, the first clamping plate 64 and the arc-shaped plate 9 with different widths and different radian can be replaced to ensure the clamping effect on the pipe fitting, so as to avoid affecting the quality of laser cladding processing.
[0040] Please refer to Figure 1 、 Figure 2 、Figure 3 and Figure 4 On one side of the mounting plate 1, a first motor 612 is fixedly connected. The first gear 611 is rotatably connected to the vertical plate 3. On the surface of the first gear 611 away from the vertical plate 3, a fixed sleeve 613 is fixedly connected. At one end of the fixed sleeve 613 away from the first gear 611, a first rectangular column 614 is fitted and installed. A cylinder 615 is sleeved outside the first rectangular column 614. On the surface of one end of the cylinder 615 close to the first motor 612 and on the surface of the output shaft of the first motor 612, first sprockets 616 are fixedly connected. The two first sprockets 616 are driven by a chain; on the surface of the cylinder 615, a mounting frame is rotatably connected. One of the mounting frames is fixedly connected to the first motor 612, and the other mounting frame is fixedly connected to the mounting plate 1.
[0041] Please refer to Figure 4 On the surface of the first gear 611 away from the vertical plate 3, a rotating block 617 is rotatably connected. On the surface of the rotating block 617 away from the first gear 611, a connecting spring 618 is fixedly connected. At one end of the connecting spring 618 away from the rotating block 617, a disc 619 is fixedly connected. The disc 619 is fixedly connected to the first rectangular column 614. At one end of the fixed sleeve 613 away from the first gear 611, grooves 620 are formed in an annular and evenly distributed manner. On the surface of the disc 619 away from the first rectangular column 614, protrusions 621 are fixedly connected in an annular and evenly distributed manner. The protrusions 621 are fitted and installed with the grooves 620;
[0042] It should be noted that by using the elastic force of the connecting spring 618, when adjusting the two vertical plates 3 to approach each other, due to the frictional force between the first rectangular column 614 and the inner wall of the cylinder 615, the protrusions 621 are separated from the grooves 620, and the disc 619 and the first rectangular column 614 are pulled by the connecting spring 618. Whenever the deformation amount of the connecting spring 618 increases, the reaction force generated by its deformation also increases, pulling the first rectangular column 614 to move together with the vertical plate 3. That is, during the movement of the vertical plate 3, the protrusions 621 and the grooves 620 are in a separated state. After the position of the vertical plate 3 is adjusted, under the elastic force of the connecting spring 618, the protrusions 621 and the grooves 620 can be fitted again. Therefore, when replacing pipe fittings of different specifications for laser cladding processing, the pipe fittings can be initially placed and positioned first, and then clamped, so as to ensure the stable clamping and positioning of pipe fittings of different specifications.
[0043] Please refer to Figure 10 On the surface of the second clamping plate 610, mounting holes 8 are symmetrically formed. In the hole walls of the two mounting holes 8, arc-shaped plates 9 are rotatably connected. At one end of the surface of the arc-shaped plate 9 away from the second clamping plate 610, an inclined plate is installed through a torsion spring;
[0044] It should be noted that during the process of the two vertical plates 3 approaching each other, the inclined plate will first come into contact with the surface of the pipe fitting. Immediately afterwards, relative movement occurs between the inclined plate and the pipe fitting, enabling the arc-shaped plate 9 to smoothly cooperate with the pipe fitting and complete the initial placement and positioning. Initially, the groove 620 and the convex block 621 are in a state of mutual cooperation. The rotation of the first sprocket 616 can drive the rotation of the first rectangular column 614 and the fixed sleeve 613, and further drive the rotation of the first gear 611. Since the inclined plate and the arc-shaped plate 9 are installed through a torsion spring, the inclined plate can closely adhere to the surface of the mounting plate 1, thereby ensuring that the pipe fitting can be smoothly clamped and positioned.
[0045] Please refer to Figure 4 , one side of the fixed column 65 is fixedly connected with a first rack column 622. A circular groove 623 is formed at one end of the surface of the first rack column 622 away from the mounting plate 1. A third T-shaped rod 624 is slidably connected to the wall of the circular groove 623. A second spring is fixedly connected to the lower end of the third T-shaped rod 624. A second rack 625 is fixedly connected to the upper end of the third T-shaped rod 624. The second rack 625 is meshed and connected with the first gear 611;
[0046] It should be noted that the first motor 612 drives the first sprocket 616 to rotate. The two first sprockets 616 rotate simultaneously. The cylinder 615 rotates as the first sprocket 616 rotates. The first rectangular column 614 rotates as the cylinder 615 rotates, and further drives the rotation of the disc 619. Under the elastic force of the connecting spring 618, the convex block 621 can cooperate with the groove 620, enabling the rotation of the first rectangular column 614 to drive the rotation of the fixed sleeve 613. The first gear 611 rotates together with the fixed sleeve 613. When adjusting the two vertical plates 3 to approach each other, the rotation of the first gear 611 drives the second rack 625, the first rack column 622, and the fixed column 65 to move away from the mounting plate 1 until the lower end of the first rack column 622 continuously meshes with, separates from, and then meshes with the first gear 611. During this process, both the arc-shaped plate 9 and the first clamping plate 64 will come into contact with the pipe fitting, completing the clamping and positioning of the pipe fitting, and being able to adapt to clamping pipe fittings of different specifications. After both the first clamping plate 64 and the arc-shaped plate 9 come into contact with the surface of the pipe fitting, relative movement occurs between the first T-shaped column 67 and the column groove 66, and the first spring 68 is compressed. Utilizing the elastic force of the first spring 68, the pipe fitting can be stably clamped;
[0047] During the process of adjusting the two vertical plates 3 to move away from each other, the rotation of the first gear 611 drives the first rack column 622, the second rack 625, and the fixed column 65 to move towards the mounting plate 1. Utilizing the elastic force and elasticity of the second spring, the first spring 68 will mesh with, separate from, and then mesh with the second rack 625.
[0048] Please refer to Figure 1 andFigure 4 , the first adjusting mechanism 4 includes a bidirectional lead screw 41 threadedly connected inside the mounting block 2. Both bidirectional lead screws 41 are rotatably connected to the mounting plate 1. One end of the bidirectional lead screw 41 is fixedly connected to a second sprocket 42. The two second sprockets 42 are driven by a chain. A transmission column 43 is fixedly connected to the surface of one of the second sprockets 42 away from the bidirectional lead screw 41. A transverse groove 44 is provided on the surface of the transmission column 43. A second T-shaped column 45 is slidably connected to the wall of the transverse groove 44. One end of the second T-shaped column 45 is fixedly connected to a third spring. The other end of the second T-shaped column 45 is fixedly connected to a second circular block 46. Second trapezoidal blocks 47 evenly distributed in a ring are fixedly connected to the surface of the second circular block 46 away from the second T-shaped column 45. A first circular block 48 is fixedly connected to a surface of the first sprocket 616 close to the transmission column 43. First trapezoidal blocks evenly distributed in a ring are fixedly connected to the surface of the first circular block 48 away from the first sprocket 616. The first trapezoidal blocks are engaged with the second trapezoidal blocks 47;
[0049] It should be noted that the transmission column 43 can be connected to the second sprocket 42 through a one-way clutch. The setting of the second sprocket 42 can be used to simultaneously adjust the rotation of the two bidirectional lead screws 41, so as to stably adjust the two vertical plates 3 to approach or move away from each other. When adjusting the two vertical plates 3 to approach each other, it can adapt to clamping pipe fittings of different lengths. When adjusting the two vertical plates 3 to move away from each other, the rotation of the first circular block 48 and the first trapezoidal blocks can stably drive the rotation of the second trapezoidal blocks 47 and the second circular block 46, ensuring that the pipe fittings can be smoothly unloaded after processing;
[0050] Specifically, the first motor 612 drives the first sprocket 616 to rotate. The first circular block 48 rotates with the rotation of the first sprocket 616. Due to the elastic force of the third spring, the first trapezoidal block is engaged with the second trapezoidal block 47. The rotation of the first circular block 48 can drive the rotation of the second circular block 46, and then drive the rotation of the two second sprockets 42. The two bidirectional lead screws 41 rotate simultaneously, and then drive the relative movement between the mounting block 2 and the mounting groove 12, so as to adjust the position of the vertical plate 3.
[0051] Please refer to Figure 8 , the initial state of the third spring is a compressed state;
[0052] It should be noted that the reaction force generated by the compression of the third spring acts on the surface of the second T-shaped column 45, so that the first trapezoidal block can be stably engaged with the second trapezoidal block 47, that is, the rotation of the first circular block 48 can smoothly drive the rotation of the second circular block. After the pipe fittings are initially placed and positioned by the two vertical plates 3 and the arc-shaped plate, relative rotation can occur between the first trapezoidal block and the second trapezoidal block 47. The first trapezoidal block and the second trapezoidal block 47 are continuously separated, then engaged, and then separated.
[0053] It should be noted that the cladding mechanism 14 includes components such as a fixed frame, a limiting sleeve, a limiting rod, a machine head, and a laser cladding head. The limiting sleeve is slidably inserted into the limiting rod, enabling the machine head and the laser cladding head to be adjusted vertically in position, which is a mature technology in the prior art and will not be elaborated here. A controller can be installed on the upper surface of the mounting plate 1 near the side of the electric slide rail 13. The electric slide rail 13, the first motor 612, and the cladding mechanism 14 are all electrically connected to the controller, and the controller is controlled by a computer.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
