Description

Technical Field

[0001] This invention belongs to the field of laser drilling technology for switch cabinets, and specifically relates to a device for drilling holes in switch cabinet bodies. Background Technology

[0002] A switch cabinet is a device used to control electrical equipment. Its basic components include two main parts: the cabinet body and the circuit breaker. The cabinet body consists of a frame, cabinet panels, electrical components (including insulation parts), various mechanisms, secondary terminals, and wiring. Because a large number of electrical components and incoming and outgoing cables need to be installed inside the switch cabinet, the cabinet panels need to be drilled. Most of the cabinet panels on the existing switch cabinet bodies are drilled by laser. Laser drilling is fast, efficient, and adaptable to various workpieces.

[0003] However, there are many types of existing switch cabinets, which results in a variety of cabinet panel specifications. In addition, there are size differences between the cabinet panels on each side of the switch cabinet. This means that when laser drilling is performed on the switch cabinet body, the fasteners need to be replaced for each switch cabinet panel of a different specification. This increases the preparation steps before laser drilling, making the operation cumbersome and reducing the drilling speed, thereby reducing the processing efficiency of the switch cabinet.

[0004] Therefore, a hole-drilling device for switch cabinet is proposed. Summary of the Invention

[0005] The present invention provides a device for drilling holes in a switch cabinet, the purpose of which is to solve the problems mentioned above.

[0006] This invention provides a switch cabinet drilling device, which includes a laser emitter mounted on a fixing frame and a cabinet panel fastening assembly mounted at the lower end of the fixing frame;

[0007] The cabinet panel fastening assembly includes a support platform. A switch cabinet panel to be fastened is placed on top of the support platform. Constraint platform 1, constraint platform 3, and constraint platform 4 are installed on top of the support platform. Constraint platform 1 and constraint platform 3 are positioned facing each other, with constraint platform 3 facing constraint platform 2 installed on top of the support platform. An electric push rod is installed in the center of the top of the support platform. The drive unit of the electric push rod is connected to constraint platform 1. Linkage rod 1 and linkage rod 2 are screwed onto the outer surface of constraint platform 4. One end of linkage rod 1 is screwed onto movable platform 1, and one end of linkage rod 2 is screwed onto movable platform 2. An adjustment assembly is installed between movable platform 2 and the support platform. A connecting rod is installed between movable platform 1 and the constraint platform. A guide seat is installed at the bottom of movable platform 1. The guide seat and the pre-adjustment assembly are connected... The guide port located at the outer edge of the top of the support platform is movable and connected. An exchange platform is installed on the top of the support platform. The exchange platform is made of aluminum sheet, and the area where the exchange platform is located overlaps with the area where the switch cabinet panel is placed. A heat dissipation exchange channel for the switch cabinet panel is installed inside the support platform. The exchange channel is curved, and a circulation component for repeatedly dissipating heat from the exchange channel is installed on the top of the support platform. The circulation component includes a rotating container installed on the top of the support platform. The exchange channel and the rotating container are connected to each other. The rotating container is filled with cold water. A cooler for dissipating heat from the cold water after use is installed inside the rotating container. A reciprocating plate is movably installed inside the rotating container. The reciprocating plate is connected to the support column and the constraint platform on its outer surface.

[0008] Furthermore, the adjusting assembly includes a tensioning screw that passes through and rotates on top of the second adjusting platform, the tensioning screw, and a mating threaded connection.

[0009] Furthermore, the interfaces are arranged in a mirror-symmetric manner, and pneumatic nozzles for removing waste from the top of the support platform are installed on the outer surface of the connecting rod. The pneumatic nozzles are connected to each other through silicone channels and air bags.

[0010] Furthermore, the air bag is installed between a pair of restraint platforms, and air is introduced through a pneumatic nozzle when the air bag contracts.

[0011] Furthermore, damping columns arranged at even intervals are installed on the four sides of the constraint platform. The damping columns are attached to the switch cabinet panel and are made of TPE material.

[0012] Furthermore, the damping column is screwed to both ends of the vertical axis and the displacement platform, and the damping column and the constraint platform are movably connected. A spiral beryllium copper wire is installed between the inner surfaces of the displacement platform and the constraint platform.

[0013] Furthermore, the support columns pass through the constraint platform and are movably connected to each other, and a spiral beryllium copper wire is installed on the outer surface of the support columns to pull them back to their original position.

[0014] The beneficial effects of this invention are as follows:

[0015] Through the linkage between constraint platform one, constraint platform two, and constraint platform four, and with the abutment of constraint platform three, multiple sides of the switch cabinet panel can be fastened simultaneously. The fastening efficiency is high while ensuring the firmness of the fastening. By changing the orientation of the variable platform two, the moving distance of constraint platform four during the fastening operation can be changed, so as to fasten switch cabinet panels of various specifications. It can adapt to the fastening of multiple specifications of switch cabinets and multiple specifications of cabinet panels without the need for repeated disassembly and assembly of switch cabinet panels, simplifying the operation and indirectly improving the efficiency of subsequent laser drilling.

[0016] The gas inside the air bag is discharged at high speed through the pneumatic nozzle. The gas impacts and cleans the waste material remaining on the top of the support platform, preventing the waste material from causing unevenness of the support platform during tightening, which could lead to unstable or even tilted placement of the switch cabinet panels. This also prevents the drilling positions on the switch cabinet panels from being slightly off-center or tilted, ensuring the accuracy of subsequent laser drilling.

[0017] By dissipating heat from the laser-drilled switch cabinet panels, the temperature of the switch cabinet panels themselves is effectively reduced, making it easier for the switch cabinet panels to be transported and stored in the future.

[0018] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0033] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 and Figure 2This invention provides a switch cabinet drilling device, comprising a fixing frame 1. A servo motor 2 is mounted in the center of the outer surface of the fixing frame 1. A ball screw 3 is mounted at the output end of the servo motor 2. A laser adjustment stage 4 is mounted on the outer surface of the ball screw 3. A pair of servo motors 5 are mounted mirror-symmetrically on the outer surface of the laser adjustment stage 4. A ball screw 6 is mounted at the output end of each pair of servo motors 5. A laser emitter 7 is mounted on the outer surface of each pair of ball screws 6. A pair of guide posts 8 are mounted mirror-symmetrically on the inner surface of the fixing frame 1. Both guide posts 8 pass through the laser adjustment stage 4. A cabinet fastening assembly 9 is mounted at the lower end of the fixing frame 1.

[0035] When drilling holes in the switch cabinet panel 92, the control servo motor 2 drives the ball screw 3 to rotate through its output end on one side. Under the guidance of the guide column 8, the laser adjustment stage 4 moves longitudinally, which in turn causes the laser emitter head 7 to move longitudinally. The control servo motors 5 work synchronously. Both servo motors 5 drive the ball screw 6 to rotate through their output ends on one side. The laser emitter head 7 moves laterally, adjusting the precise position of the laser emitter head 7. The laser emitted by the laser emitter head 7 irradiates the switch cabinet panel 92 to achieve laser drilling.

[0036] Reference Figures 3-6 The cabinet fastening assembly 9 includes a support platform 91. A switch cabinet panel 92 to be fastened is placed on the top of the support platform 91. Constraint platforms 1 93, 3 95, and 4 96 are installed on the top of the support platform 91. Constraint platforms 1 93 and 3 95 face each other, with constraint platform 3 95 facing constraint platform 2 94 installed on the top of the support platform 91. An electric push rod 97 is installed in the center of the top of the support platform 91. The drive unit of the electric push rod 97 is connected to constraint platform 1 93. Linkage rod 1 98 and linkage rod 2 911 are screwed onto the outer surface of constraint platform 4 96. Linkage rod 1 98... One end of the 8 is screwed to the first 99 of the variable platform, and the other end of the second 911 of the linkage rod is screwed to the second 912 of the variable platform. An adjustment component is installed between the second 912 of the variable platform and the support platform 91. A connecting rod 910 is installed between the first 99 of the variable platform and the first 93 of the constraint platform. A guide seat 9102 is installed at the bottom of the first 99 of the variable platform. The guide seat 9102 and the guide port 9101 reserved at the outer edge of the top of the support platform 91 are movably connected. The adjustment component includes a tension screw 913 that passes through and rotates on the top of the second 912 of the variable platform. The tension screw 913 is screwed to the interface 914. The interface 914 is arranged in a mirror symmetrical manner.

[0037] In actual operation, the switch cabinet panel 92 is first placed on the corresponding area on the top of the support platform 91. Then, the electric push rod 97 is controlled to drive the constraint platform 93 to move through the drive part at one end. During the movement, the constraint platform 93 uses the connecting rod 910 on the outer surface to pull the moving platform 99 to move together (at this time, the guide seat 9102 at the bottom of the moving platform 99 is displaced in the guide opening 9101 to prevent the trajectory of the moving platform 99 from being misaligned). During the movement, the moving platform 99 pulls the linkage rod 98 and the linkage rod 911 to rotate, and then the linkage rod 98 and the linkage rod 911 pull the constraint platform 96 towards the center area until the constraint platform 93, the pair of constraint platforms 96 and the constraint platform 95 simultaneously tighten the switch cabinet panel 92 from multiple directions to enhance stability.

[0038] When dealing with switchgear panels 92 of various specifications, the operator first unscrews the tension screw 913, disassembles the second variable platform 912 and the support platform 91, then pulls the second variable platform 912 to the corresponding area, and finally passes the tension screw 913 through the second variable platform 912 and screws it into the interface 914 to complete the fastening of the second variable platform 912. Under the above steps, the starting point of the second variable platform 912 is adjusted, and then the displacement distance of the fourth constraint platform 96 during fastening is adjusted in order to fasten switchgear panels 92 of various specifications.

[0039] Reference Figures 9-12 The outer surface of the connecting rod 910 is equipped with a pneumatic nozzle 925 for removing waste material from the top of the bearing platform 91. The pneumatic nozzle 925 is connected to the air bag 926 via a silicone channel 927. The air bag 926 is installed between a pair of constraint platforms 93. When the air bag 926 contracts, air is introduced through the pneumatic nozzle 925. The inner surface of the constraint platform 96 is equipped with damping columns 915 arranged at even intervals. The damping columns 915 are attached to the switch cabinet panel 92 and are made of TPE material. The two ends of the damping columns 915 are screwed to the displacement platform 916. The damping columns 915 and the constraint platform 96 are movably connected. A spiral beryllium copper wire 917 is installed between the inner surfaces of the displacement platform 916 and the constraint platform 96.

[0040] During the tightening process, the damping column 915 inside the constraint platform 96 first abuts against the switch cabinet panel 92. When the damping column 915 is under pressure, it pulls the displacement platforms 916 at both ends of its vertical sides to move on the inner surface of the constraint platform 96. Then, the displacement platforms 916 are driven to press the spiral beryllium copper wire 917. The deformation of the spiral beryllium copper wire 917 plays a role in pressure reduction and protection, preventing damage to the switch cabinet panel 92. After the laser drilling of the switch cabinet panel 92 is completed, the electric push rod 97 retracts to release all the tightening. At this time, the electric push rod 97 pulls a pair of constraint platforms 93 to approach each other, and then the constraint platforms 93 press the air bag 926. Then, the gas in the air bag 926 is discharged at high speed from the pneumatic nozzle 925 through the silicone channel 927. The gas impacts and cleans the waste material remaining on the top of the support platform 91, ensuring the subsequent tightening operation.

[0041] Reference Figure 3 , Figure 7 and Figure 8 A switching platform 918 is mounted on top of the support platform 91. The switching platform 918 is made of aluminum sheet, and its location overlaps with the area where the switch cabinet panel 92 is placed. Inside the support platform 91, a heat dissipation channel 919 for the switch cabinet panel 92 is installed. The heat dissipation channel 919 is curved, and a circulating assembly for repeatedly dissipating heat from the heat dissipation channel 919 is installed on top of the support platform 91. The circulating assembly includes a rotating container 920 mounted on top of the support platform 91, the heat dissipation channel 919, and a rotating... The containers 920 are connected to each other. The rotary container 920 is filled with cold water. A chiller 921 is installed inside the rotary container 920 to dissipate heat from the used cold water. A reciprocating plate 922 is movably installed inside the rotary container 920. The reciprocating plate 922 is connected to the constraint platform 3 95 via a support column 923 on its outer surface. The support column 923 passes through the constraint platform 2 94 and is movably connected to each other. A spiral beryllium copper wire 2 924 for pulling the support column 923 back is installed on its outer surface.

[0042] After the fastening is completed, the switch cabinet panel 92 presses against the constraint platform 95, which, with the cooperation of the bearing column 923, pulls the reciprocating plate 922 to move within the rotary container 920. This forces the cold water in the rotary container 920 into the exchange channel 919, enhancing the heat dissipation performance of the exchange channel 919 (heat exchange is achieved through the cooperation of the exchange platform 918 and the exchange channel 919, dissipating heat from the switch cabinet panel 92 during laser drilling). After the laser drilling is completed, the fastening of the switch cabinet panel 92 is released. At this moment, with the cooperation of the spiral beryllium copper wire 924, the bearing column 923 pulls the reciprocating plate 922 to move in the opposite direction, reducing the air pressure inside the rotary container 920. Under the pressure difference, the cold water in the exchange channel 919 is drawn back into the rotary container 920. At this moment, the chiller 921 inside the rotary container 920 removes heat from the cold water, ensuring its subsequent heat removal function.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
