DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0033] Embodiment 1

[0034] like Figure 1 As shown, a laser cladding device for repairing shaft parts includes a box 1, which is a rectangular bracket. When the device performs laser cladding on the workpiece, the workpiece can be moved into the box 1, so that the cladding effect of the workpiece can be better observed, and at the same time, it is ensured that the raw materials during cladding will not float around, which is convenient for collection. The inner cavity of the box 1 is provided with a lifting frame 2 for adjusting the height of the workpiece. After the workpiece is fixed, the height of the workpiece can be adjusted by using the lifting frame 2. When clamping and fixing, the workpiece also needs to be pushed to the corresponding position by the lifting frame 2, and it will not affect the normal rotation of the workpiece.

[0035] Then, a cladding mechanism 3 for supporting the workpiece is provided at the rear side of the lifting frame 2. When the workpiece is not fixed, it can be placed on the cladding mechanism 3, and then the workpiece can be moved to the corresponding position by the lifting frame 2. It is inconvenient to clamp and fix the workpiece by hanging it, and when the device performs cladding on the workpiece, the cladding mechanism 3 will not contact the workpiece, which will not affect the cladding effect of the device, and the high-temperature cladding layer will not contact the device, ensuring the service life of the device. A fixing mechanism 4 for fixing the workpiece is provided between the lifting frame 2 and the cladding mechanism 3;

[0036] Then, after the workpiece is clamped and fixed by the fixing mechanism 4, the lifting frame 2 and the fixing mechanism 4 can be used to keep the workpiece in a horizontal state at all times, and the fixing mechanism 4 can also drive the workpiece to rotate during cladding and grinding, making the device more convenient to use and workers can also load and unload materials better.

[0037] Further explanation, in order to be able to adjust the position height of the workpiece, such as Figure 2 As shown, the lifting frame 2 includes a support plate 21, which supports the components. A motor 22 is fixedly installed on the upper end of the support plate 21, and a reciprocating screw 23 is fixedly installed on the output end of the motor 22. Starting the motor 22 can drive the reciprocating screw 23 to rotate. A movable plate 24 is threadedly connected to the surface of the reciprocating screw 23. The support plate 21 will limit the movable plate 24 so that it cannot rotate with the reciprocating screw 23. Under the action of the threaded connection, when the reciprocating screw 23 rotates, the movable plate 24 can move up and down along the reciprocating screw 23 to adjust the position height of the workpiece;

[0038] Then, a rectangular groove is provided at the rear end of the movable plate 24, in which a cylinder 25 is fixedly installed, and an extrusion frame 26 is fixedly installed at the output end of the cylinder 25. Starting the cylinder 25 can drive the extrusion frame 26 to move left and right. The extrusion frame 26 is slidably installed at the rear end of the movable plate 24, and the sliding method can ensure that there will be no deviation when the extrusion frame 26 moves. A top platform 27 is rotatably installed in the middle of one end of the extrusion frame 26 close to the cylinder 25. When the workpiece is pushed to move, the top platform 27 contacts with the workpiece, so it will not affect the fixing mechanism 4 to drive the workpiece to rotate;

[0039] Specifically, the air cylinder 25 is started to pull the extrusion frame 26 and the top platform 27 to move to the right, and when the top platform 27 contacts the surface of the workpiece, it will push it to move.

[0040] Further explanation, in order to support the workpiece before fixing, such as Figure 3 As shown, the cladding mechanism 3 includes a base 31, which is connected to the movable plate 24 so that the base 31 can move with the movable plate 24. A laser cladding gun 32 is slidably installed on the upper end of the base 31. The workpiece is clad by the laser cladding gun 32, and the laser cladding gun 32 can move left and right, so that any part of the workpiece can be repaired. Two support frames 33 are rotatably installed at the front end of the base 31. Before clamping and fixing, the two support frames 33 are used to support the workpiece. The surfaces of the two support frames 33 are relatively smooth. When the top platform 27 pushes the workpiece to move, no large friction will be generated.

[0041] Then, the rotation axes of the two support frames 33 are connected to each other, so the two support frames 33 will rotate at the same time, and a transmission gear 34 is rotatably installed at the front end of the base 31. Two mutually meshing bevel gears 35 are provided on the front side of the transmission gear 34. The two bevel gears 35 can rotate at the same time. The bevel gear 35 on the upper side is connected to the transmission gear 34. When the transmission gear 34 rotates, it can drive the bevel gear 35 on the upper side to rotate;

[0042] Then, the bevel gear 35 located at the lower side is connected to the rotating shafts of the two support frames 33. When the bevel gear 35 located at the lower side rotates, it can drive the two support frames 33 to rotate at the same time. The lower side of the transmission gear 34 is meshed with a rack 36 slidably mounted on the surface of the base 31. Under the meshing action, the transmission gear 34 needs to be driven to rotate by moving the rack 36;

[0043] Specifically, the rack 36 drives the transmission gear 34 to rotate, and the transmission gear 34 drives the two bevel gears 35 to rotate simultaneously, and the bevel gear 35 located at the lower side drives the two support frames 33 to rotate downward without contacting the workpiece.

[0044] It should be noted that in order to prevent the two support frames 33 from contacting the workpiece, the transmission gear 34 and the bevel gear 35 on the upper side need to rotate clockwise, so that the bevel gear 35 on the lower side can drive the two support frames 33 to rotate downward.

[0045] Further explanation, in order to be able to clamp the workpiece, such as Figure 4 , Figure 5 as well as Figure 6 As shown, the fixing mechanism 4 includes an adjusting component 41, through which the components are supported, a housing 42 is rotatably installed in the adjusting component 41, and damping is provided at the rotating parts of the housing 42 and the adjusting component 41, so that there is a large friction force between the adjusting component 41 and the housing 42, a clamping plate 43 is rotatably installed in the inner cavity of the housing 42, and two clamping blocks 44 are slidably installed in the housing 42, the clamping blocks 44 are limited by the housing 42, and then the two clamping blocks 44 can be moved in opposite directions by rotating the clamping plate 43;

[0046] Then, a telescopic rod 45 is provided in the middle of the inner cavity of the shell 42, and the telescopic rod 45 can be extended and retracted. When the workpiece is pushed and moved by the top platform 27, it will contact the end face of the telescopic rod 45, and then the workpiece will move again, which will push the telescopic rod 45 to retract. The output end of the telescopic rod 45 is connected to the rack 36, and the rack 36 will move with the retraction of the telescopic rod 45. A limit frame 46 is slidably installed on the surface of the shell 42, and the limit frame 46 can limit the loose belt. When the shell 42 rotates, the loose belt in the clamping disk 43 will always be located in the clamping disk 43 without affecting the rotation of the shell 42;

[0047] Specifically, when the clamping plate 43 is driven to rotate, the friction between the shell 42 and the adjustment assembly 41 prevents the shell 42 from rotating with the clamping plate 43 , and the laser cladding only requires slowly rotating the workpiece, and the shell 42 does not need to rotate quickly.

[0048] It should be noted that when the workpiece contacts the telescopic rod 45, it has moved to a position very close to the shell 42. At this time, the rack 36 is driven to move by the telescopic rod 45 so that the support frame 33 does not contact the workpiece. At this time, the workpiece will be supported by the two clamping blocks 44, and the workpiece will not fall without the support frame 33.

[0049] To further explain, in order to be able to drive the clamping plate 43 and the housing 42 to rotate respectively, as shown in FIG. Figure 7 As shown, the adjustment component 41 includes an arc frame 411, a telescopic rod 45 is fixedly installed on the surface of the arc frame 411, and a limit frame 46 is fixedly installed on the surface of the arc frame 411, so the telescopic rod 45 and the limit frame 46 will be fixed in place and will not rotate with the shell 42 and the clamping plate 43. An arc groove is provided on the end surface of the arc frame 411, and an adjustment rod 413 is provided in the arc groove. The left and right sides of the arc groove are provided with pulleys 412 rotatably installed on the end surface of the arc frame 411. The pulley 412 and the adjustment rod 413 cooperate with each other. When the device needs to be clamped, the adjustment rod 413 can drive the pulley 412 on the right side to rotate. When the device needs to perform cladding work, the adjustment rod 413 needs to drive the pulley 412 on the left side to rotate.

[0050] Then, the adjusting rod 413 can only drive one of the pulleys 412 to rotate, a motor 2 414 is provided on the right side of the arc frame 411, and a tensioning pulley 415 is fixedly installed on the right end of the arc frame 411. The pulley 412 on the left side is connected to the outer shell 42 by a belt, and the outer shell 42 can be driven to rotate by the pulley 412 on the left side. The pulley 412 on the right side, the tensioning pulley 415 and the inner wall of the clamping disk 43 are wrapped with a belt, and the clamping disk 43 can be driven to rotate by the pulley 412 on the right side.

[0051] It should be noted that when the housing 42 needs to be driven to rotate, the tensioning wheel 415 needs to be started to extend it, so that the belts on the surface of the tensioning wheel 415 and the clamping plate 43 are loosened, which will not affect the rotation of the housing 42.

[0052] The specific implementation of this embodiment is as follows: the workpiece is placed on the two support frames 33, and the cylinder 25 is started to pull the extrusion frame 26 and the top platform 27 to move to the right. When the top platform 27 contacts the surface of the workpiece, it will push it to move. After the workpiece moves a certain distance, it will contact the end face of the telescopic rod 45, and then the telescopic rod 45 is pushed to shrink. The telescopic rod 45 will drive the rack 36 to move to the right. Under the meshing action, the rack 36 will drive the transmission gear 34 to rotate, and the transmission gear 34 will drive the two bevel gears 35 to rotate at the same time. The bevel gear 35 on the lower side will drive the two support frames 33 to rotate downward without contacting the workpiece.

[0053] After the workpiece moves to the corresponding position, it will be squeezed by the top platform 27 and the shell 42 to keep it in a horizontal state, and then the second motor 414 is started to drive the adjusting rod 413 to rotate, and the adjusting rod 413 will drive the adjusting rod 413 on the right to rotate, and then the clamping plate 43 will rotate, and the two clamping blocks 44 will move towards each other. When the clamping blocks 44 contact the workpiece, they will clamp it and fix it, and then the tensioning wheel 415 is started to extend it, so that the belt wrapped around the surface of the clamping plate 43 is loosened;

[0054] After the fixation is completed, start the motor 22 to drive the reciprocating screw 23 to rotate. Under the action of the threaded connection, the movable plate 24 will move downward along the reciprocating screw 23, so that the workpiece is located inside the box 1, and then start the tensioning wheel 415 again to drive the adjusting rod 413 to rotate. In fact, the adjusting rod 413 will drive the pulley 412 on the left to rotate, and the pulley 412 on the left will drive the outer shell 42 and the workpiece to rotate at the same time, so that the laser cladding gun 32 can be used to perform cladding work on the surface of the workpiece.

[0055] Embodiment 2

[0056] This embodiment is a further improvement on the adjustment rod 413 based on the first embodiment, so that the device can drive the two pulleys 412 to rotate respectively under different states through the second motor 414 and the adjustment rod 413.

[0057] Further explanation, in order to be able to drive the two pulleys 412 to rotate respectively, as Figure 8 and Fig. 9As shown, the adjusting rod 413 includes a tube body 4131, and hydraulic oil is arranged in the tube body 4131. A second telescopic rod 4132 is fixedly installed in the inner cavity of the tube body 4131. A sealing gasket 4133 is fixedly installed at the output end of the second telescopic rod 4132. The arc surface of the sealing gasket 4133 is tightly fitted with the inner wall of the tube body 4131. When the second telescopic rod 4132 drives the sealing gasket 4133 to move, the hydraulic oil in the tube body 4131 will be pushed out by the sealing gasket 4133. The left and right ends of the tube body 4131 are fixedly installed with a shell 4134, and a notch is opened on the surface of the shell 4134.

[0058] Then, the shell 4134 on the right side is connected to the output end of the motor 2 414, and hydraulic pipes 4135 are fixedly installed in the two shells 4134. The two hydraulic pipes 4135 are connected with the tube body 4131, and the hydraulic oil in the tube body 4131 will enter the hydraulic pipe 4135. Four piston plates 4136 are slidably installed in the inner cavities of the two hydraulic pipes 4135, and the hydraulic oil will push the four piston plates 4136 to move in opposite directions.

[0059] It should be noted that when the telescopic rod 4132 drives the sealing gasket 4133 to move to the right, the hydraulic oil in the tube body 4131 will enter the hydraulic pipe 4135 on the right side; when the telescopic rod 4132 drives the sealing gasket 4133 to move to the left, the hydraulic oil in the tube body 4131 will enter the hydraulic pipe 4135 on the left side, and the hydraulic oil in the hydraulic pipe 4135 on the right side will also be drawn out.

[0060] The specific implementation of this embodiment is as follows: when it is necessary to drive the pulley 412 on the right side to rotate, the telescopic rod 4132 is needed to drive the sealing gasket 4133 to move to the right, and the hydraulic oil in the tube body 4131 will enter the hydraulic pipe 4135 on the right side; when it is necessary to drive the pulley 412 on the left side to rotate, the telescopic rod 4132 is needed to drive the sealing gasket 4133 to move to the left, and the hydraulic oil in the tube body 4131 will enter the hydraulic pipe 4135 on the left side; when the hydraulic oil enters the hydraulic pipe 4135, the four piston plates 4136 in the hydraulic pipe 4135 will move away from each other, and the piston plates 4136 will be stuck in the groove of the pulley 412, and the starting motor 414 can drive the pulley 412 to rotate.

[0061] It should be noted that the specific installation method, circuit connection method and control method of the motor 1 22, the laser cladding gun 32 and the motor 2 414 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
