Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting, and particularly to a laser cutting device for the processing of high-voltage vacuum circuit breakers. Background Art

[0002] A high-voltage vacuum circuit breaker is a circuit breaker that uses vacuum as the arc extinguishing and insulating medium, mainly used in medium and high-voltage power systems, and has the characteristics of strong breaking ability, long service life, environmental protection, and simple maintenance. The bellows in the high-voltage vacuum circuit breaker is a key component - a key element in the vacuum interrupter, which directly affects the mechanical life and sealing performance of the circuit breaker. Therefore, the cutting and processing of the bellows are particularly important.

[0003] However, for the cutting of the existing bellows, the bellows to be cut are placed on the cutting platform, and a high-energy laser beam is focused to locally cut the bellows. When cutting the bellows, the cutting platform is not convenient for fixing bellows of different diameters and locking the cutting position, resulting in deviation of the cutting position of the bellows, affecting the production quality of the bellows. At the same time, a large amount of metal debris with accumulated heat will fly during cutting and adhere to the cutting platform, which is more troublesome to clean and affects the cutting efficiency of the bellows.

[0004] In view of the above problems, it is urgent to innovate and design on the basis of the original laser cutting device for the processing of high-voltage vacuum circuit breakers. Summary of the Invention

[0007] The adjusting mechanism includes a rotating rod, which is horizontally installed in the middle of the cutting platform through a driving motor on one side of the cutting platform. An active bevel gear is sleeved in the middle area of the rotating rod. A screw rod is rotatably connected to the inner side wall of the cutting platform. A moving plate is arranged around the screw rod. Through grooves are formed on both sides of the bottom of the moving plate. On both sides of the top of the cutting platform, there are abutting blocks corresponding to the through grooves. A telescopic plate is sleeved in the moving plate. A resisting rod is arranged at the bottom of the telescopic plate inside the moving plate. An adsorption component is installed at one end of the telescopic plate away from the cutting platform.

[0008] Preferably, the positioning component includes a shell, the top of the shell is fixedly connected to both sides of the bottom of the laser cutting head. Inside the shell, a probe is installed and limited by a first spring. There are two groups of probes, and the bottoms of the two groups of probes extend out of the inside of the shell and are horizontally arranged. An inductor is installed at the top end of the inner wall of the shell.

[0009] Preferably, the adsorption component includes a first oil tank, which is fixedly installed on one side of the moving plate away from the cutting platform. A first piston rod is slidably limited inside the first oil tank. The output end of the first piston rod is fixed to the telescopic plate through a fixing plate. A second oil tank is fixedly installed inside one end of the telescopic plate above the cutting platform. A second piston rod is slidably limited inside the second oil tank. A second spring is sleeved on the surface of the second piston rod. The output end of the second piston rod is provided with a negative pressure suction head, and the negative pressure suction head is slidably limited through a chute at one end of the telescopic plate above the cutting platform.

[0010] Preferably, the other end of the screw rod is provided with a driven bevel gear, which is meshed and connected with the active bevel gear. Two rotating wheels are symmetrically installed on both sides of the periphery of the rotating rod. An electric push rod is arranged inside the rotating rod through the rotating rod. The push rod is slidably connected inside the rotating rod. A clamping block is sleeved in the middle area of the rotating rod. The bottom end of the push rod is connected to the clamping block through a through groove.

[0011] Preferably, both sides of the periphery of the active bevel gear are rotatably connected to the inner wall of the central cavity of the cutting platform through bearings. The clamping block is in a prismatic structure, and a rhombic clamping groove is formed on the surface of the active bevel gear corresponding to the clamping block.

[0012] Preferably, the telescopic plate is set in an "L" shape. A sleeve is arranged at the middle position of the bottom of the moving plate corresponding to the screw rod. The sleeve is sleeved on the periphery of the screw rod, and the sleeve is threadedly connected to the peripheral surface of the screw rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, a centering gripper, a cutting platform, an adjusting mechanism, a housing, a first spring, a probe and a sensor are provided. The two ends of the corrugated pipe to be cut are clamped and fixed by the centering gripper. During the clamping process, the adjusting mechanism is used to fix the area to be cut of the corrugated pipes with different diameters. The laser cutting head is moved above the area to be cut by a screw jack, and the laser cutting head is driven to move left and right by a moving guide rail, so that the probe touches the periphery of the corrugated pipe and moves until the sensor senses that the two probes are in a horizontal position, and then the moving guide rail is closed to lock the cutting position. This solves the problem that the existing cutting platform is not convenient for fixing and adjusting corrugated pipes with different diameters and accurately locking the cutting position, resulting in deviation of the cutting position of the corrugated pipe and affecting the production quality of the corrugated pipe.

[0018] 2. In the present invention, a first oil tank, a first piston rod, a second oil tank, a second piston rod, a second spring and a negative pressure suction head are provided. When the adjusting mechanism adjusts corrugated pipes with different diameters, it will drive the first piston rod to squeeze or release the oil in the first oil tank, so that the oil in the first oil tank is input or output to the second oil tank through a hose to squeeze or release the second piston rod, so that the second piston rod adjusts the negative pressure suction head as the adjusting mechanism operates, ensuring that the position of the negative pressure suction head always remains in the same position to adsorb a large amount of heat-accumulating metal debris during cutting. This solves the problem that the cleaning of the splashed metal debris attached to the cutting platform is relatively inconvenient, which affects the cutting efficiency of the corrugated pipe.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figures 1-8 , the present invention provides a technical solution: a laser cutting device for the processing of high-voltage vacuum circuit breakers, including a device table 1, a controller 14 is installed on one side of the device table 1, centering chucks 2 are installed on both sides of the top of the device table 1, the bellows to be cut is placed on the centering chucks 2, and both ends of the bellows are clamped and fixed by the centering chucks 2. A moving block 3 is installed at the center position of the rear side of the top of the device table 1 through a screw jack, and a laser cutting head 5 is installed on the front side of the moving block 3 through a moving guide rail 4. A bottom plate 6 is installed at the center position of the top of the device table 1, and a cutting platform 8 is installed on the top of the bottom plate 6 through an electric push rod 7. The controller 14 controls the electric push rod 7 in the bottom plate 6 to push the cutting platform 8 upward until the rotating wheel 11 fits the bottom surface of the cut bellows. An adjusting mechanism is installed in the cutting platform 8, and positioning components are horizontally installed on both sides of the bottom end of the laser cutting head 5;

[0030] The adjusting mechanism includes a rotating rod 91, which is horizontally installed in the middle of the cutting platform 8 through a driving motor on one side of the cutting platform 8. A driving bevel gear 92 is sleeved in the middle area of the rotating rod 91. The two sides of the periphery of the driving bevel gear 92 are rotationally connected to the inner wall of the central cavity of the cutting platform 8 through bearings. A screw rod 94 is rotationally connected to the inner side wall of the cutting platform 8. A moving plate 95 is arranged on the periphery of the screw rod 94. Through grooves are formed on both sides of the bottom of the moving plate 95. Corresponding to the through grooves on both sides of the top of the cutting platform 8, there are abutting blocks 96. The two groups of abutting blocks 96 are symmetrically arranged on both sides of the top of the cutting platform 8. The abutting blocks 96 are arranged in an inclined structure with the inclined surface facing upward. A telescopic plate 97 is sleeved in the moving plate 95. A resisting rod 98 is arranged at the bottom of the telescopic plate 97 inside the moving plate 95. One end of the telescopic plate 97 away from the cutting platform 8 is provided with an adsorption component. The telescopic plate 97 is arranged in an "L" shape. A sleeve is arranged at the middle position of the bottom of the moving plate 95 corresponding to the screw rod 94. The sleeve is sleeved on the periphery of the screw rod 94, and the sleeve is threadedly connected to the peripheral surface of the screw rod 94;

[0031] As an implementation manner of the present invention, when the driving motor drives the rotating rod 91 to rotate clockwise, it drives the driving bevel gear 92 to rotate clockwise. The clockwise rotation of the driving bevel gear drives the driven bevel gear 93 to rotate relatively. The relative rotation of the driven bevel gear 93 drives the screw rod 94 to rotate relatively. The relative rotation of the screw rod 94 drives the moving plates 95 to approach each other. When the moving plates 95 approach each other, the resisting rod 98 at the bottom of the telescopic plate 97 drives the telescopic plate 97 to move downward under the action of the inclined surface of the abutting block 96 in cooperation with the resilience of the spring. When the driving motor drives the rotating rod 91 to rotate counterclockwise, it drives the driving bevel gear 92 to rotate counterclockwise. The counterclockwise rotation of the driving bevel gear drives the driven bevel gear 93 to rotate relatively. The relative rotation of the driven bevel gear 93 drives the screw rod 94 to rotate relatively. The relative rotation of the screw rod 94 drives the moving plates 95 to move away from each other. When the moving plates 95 move away from each other, the resisting rod 98 at the bottom of the telescopic plate 97 drives the telescopic plate 97 to move upward under the abutting action of the inclined surface of the abutting block 96 until the moving plate 95 and the telescopic plate 97 are attached to the outer wall of the corrugated pipe to fix the area to be cut of the corrugated pipe.

[0032] As an implementation manner of the present invention, the positioning component includes a housing 101. The top of the housing 101 is fixedly connected to both sides of the bottom of the laser cutting head 5. A probe 103 is installed in the housing 101 through the limitation of a first spring 102. There are two groups of probes 103. The bottoms of the two groups of probes 103 extend out of the inside of the housing 101 and are horizontally arranged. An inductor 104 is installed at the top end of the inner wall of the housing 101. The laser cutting head 5 is driven to move left and right through the moving guide rail 4. The left and right movement of the laser cutting head 5 drives the probes 103 on both sides of it to move along the outer surface of the corrugated pipe until the inductor 104 senses that the two probes 103 are in a horizontal position, and the controller 14 closes the moving guide rail 4 so that the laser cutting head 5 can accurately lock the cutting position.

[0033] As an implementation manner of the present invention, the adsorption assembly includes a first oil tank 991, the first oil tank 991 is fixedly installed on the side of the moving plate 95 away from the cutting platform 8. A first piston rod 992 is slidably limited inside the first oil tank 991. The output end of the first piston rod 992 is fixed on the telescopic plate 97 through a fixing plate. A second oil tank 993 is fixedly installed inside the telescopic plate 97 at the upper end above the cutting platform 8. A second piston rod 994 is slidably limited inside the second oil tank 993. A second spring 995 is sleeved on the surface of the second piston rod 994. The output end of the second piston rod 994 is provided with a negative pressure suction head 996. The negative pressure suction head 996 is slidably limited at one end of the telescopic plate 97 above the cutting platform 8 through a chute. The negative pressure suction head 996 is connected to an external negative pressure device through a negative pressure hose. The upper oil chamber of the first oil tank 991 is connected to the lower oil chamber of the second oil tank 993 through a hose. When moving on the telescopic plate 97, it will drive the first piston rod 992 to squeeze the oil in the first oil tank 991, so that the oil in the first oil tank 991 is input into the second oil tank 993 through the hose. When moving downward on the telescopic plate 97, it will drive the first piston rod 992 to release the oil in the first oil tank 991, so that the oil in the second oil tank 993 is input into the first oil tank 991 through the hose under the action of the second spring 995, so that the second piston rod 994 adjusts the negative pressure suction head 996 as the telescopic plate 97 adjusts and operates, ensuring that the position of the negative pressure suction head 996 always remains in the same position.

[0034] As an implementation manner of the present invention, the other end of the screw 94 is provided with a driven bevel gear 93, the driven bevel gear 93 is meshed and connected with the driving bevel gear 92. Rotating wheels 11 are symmetrically installed on both sides of the periphery of the rotating rod 91. A push rod 12 is arranged inside the rotating rod 91 through an electric push rod 7. The push rod 12 is slidably connected inside the rotating rod 91. A clamping block 13 is sleeved in the middle area of the rotating rod 91. The bottom end of the push rod 12 is connected to the clamping block 13 through a through groove. The clamping block 13 has a prismatic structure. A diamond-shaped clamping groove is opened on the surface of the driving bevel gear 92 corresponding to the clamping block 13. The controller 14 controls the driving motor to drive the rotating rod 91 to rotate, so that the clamping block 13 is clamped into the diamond-shaped clamping groove opened on the surface of the driving bevel gear 92. When the adjustment is completed, the electric push rod 7 pulls the push rod 12 to move, so that the clamping block 13 disengages from the inside of the diamond-shaped clamping groove.

[0035] Working principle: When using the laser cutting equipment processed by this high-voltage vacuum circuit breaker, first place the bellows to be cut on the centering gripper 2, and clamp and fix both ends of the bellows through the centering gripper 2. When dealing with bellows of different diameters, the controller 14 controls the electric push rod 7 in the bottom plate 6 to push the cutting platform 8 upward until the rotating wheel 11 fits the bottom surface of the bellows to be cut. The controller 14 controls the electric push rod 7 to push the push rod 12 to move, and controls the driving motor through the controller 14 to drive the rotating rod 91 to rotate, so that the clamping block 13 is clamped into the diamond-shaped card slot opened on the surface of the driving bevel gear 92. When the driving motor drives the rotating rod 91 to rotate clockwise, it drives the driving bevel gear 92 to rotate clockwise. The driving bevel gear rotates clockwise to drive the driven bevel gear 93 to rotate relatively. The driven bevel gear 93 rotates relatively to drive the screw rod 94 to rotate clockwise. The screw rod 94 rotates relatively to drive the moving plates 95 to approach each other. When the moving plates 95 approach each other, the contact rod 98 at the bottom of the telescopic plate 97 drives the telescopic plate 97 to move downward under the action of the inclined surface of the contact block 96 and in cooperation with the resilience of the spring. When the driving motor drives the rotating rod 91 to rotate counterclockwise, it drives the driving bevel gear 92 to rotate counterclockwise. The driving bevel gear rotates counterclockwise to drive the driven bevel gear 93 to rotate relatively. The driven bevel gear 93 rotates relatively to drive the screw rod 94 to rotate relatively. The screw rod 94 rotates relatively to drive the moving plates 95 to move away from each other. When the moving plates 95 move away from each other, the contact rod 98 at the bottom of the telescopic plate 97 drives the telescopic plate 97 to move upward under the contact action of the inclined surface of the contact block 96 until the moving plates 95 and the telescopic plate 97 fit on the outer wall of the bellows to fix the area of the bellows to be cut. At this time, the electric push rod 7 pulls the push rod 12 to move, so that the clamping block 13 disengages from the inside of the diamond-shaped card slot;

[0036] When moving on the telescopic plate 97, it will drive the first piston rod 992 to extrude the hydraulic oil in the first hydraulic oil tank 991, so that the hydraulic oil in the first hydraulic oil tank 991 is input into the second hydraulic oil tank 993 through the hose. When moving under the telescopic plate 97, it will drive the first piston rod 992 to release the hydraulic oil in the first hydraulic oil tank 991, so that the hydraulic oil in the second hydraulic oil tank 993 is input into the first hydraulic oil tank 991 through the hose under the action of the second spring 995. The second piston rod 994 adjusts the negative pressure suction head 996 along with the adjustment operation of the telescopic plate 97 to ensure that the position of the negative pressure suction head 996 always remains in the same position to adsorb metal debris. Finally, the moving guide rail 4 drives the laser cutting head 5 to move left and right. The left and right movement of the laser cutting head 5 drives the probes 103 on both sides of it to move along the outer surface of the bellows until the sensor 104 senses that the two probes 103 are in the horizontal position. Then the controller 14 closes the moving guide rail 4, so that the laser cutting head 5 can accurately lock the cutting position. Subsequently, the laser cutting head 5 is started to cut the surface of the bellows. While cutting, the driving motor drives the rotating rod 91 to rotate, driving the rotating wheel 11 to rotate. The rotation of the rotating wheel 11 drives the bellows to rotate, so that the laser cutting head 5 cuts along the outer circumference of the bellows to complete the cutting task of the bellows.
