Description

Technical Field

[0001] The invention belongs to the technical field of laser drilling of switch cabinets, and in particular relates to a switch cabinet body drilling device. Background Art

[0002] A switch cabinet is a device used to control electrical equipment. Its basic components include a cabinet body and a circuit breaker. The cabinet body consists of a frame, a cabinet panel, electrical components (including insulating parts), various mechanisms, secondary terminals and connections. Since a large number of electrical components and inlet and outlet cables need to be installed in the switch cabinet, the cabinet panels need to be punched. Most of the cabinet panels on the existing switch cabinet bodies are punched by laser. Laser drilling is fast, efficient, and suitable for various workpieces.

[0003] However, there are many types of existing switch cabinets, which results in many specifications of cabinet panels that make up the switch cabinets. In addition, there are size differences between the cabinet panels on each side of the switch cabinet. As a result, when the switch cabinet body is laser drilled, fasteners need to be replaced each time a switch cabinet panel of a certain specification is fastened, which increases the preparation steps before laser drilling, makes the operation cumbersome, and reduces the drilling speed, thereby reducing the processing efficiency of the switch cabinet.

[0004] Therefore, a switch cabinet body punching device is proposed. Summary of the invention

[0005] The present invention provides a switch cabinet body punching device, which aims to solve the above-mentioned problems.

[0008] Furthermore, the adjustment component includes a tensioning screw that passes through and rotates on the top of the second variable platform, and the tensioning screw is threadedly connected to the docking port.

[0009] Furthermore, the docking interfaces are arranged in mirror symmetry, and a pneumatic nozzle for removing waste from the top of the supporting platform is installed on the outer surface of the connecting rod, and the pneumatic nozzles are connected to each other via a silicone channel and an inflatable bag.

[0010] Furthermore, an inflatable bag is arranged between a pair of restraint platforms, and air is introduced into the inflatable bag through a pneumatic nozzle when the inflatable bag is deflated.

[0011] Furthermore, damping columns arranged at even intervals are arranged on the four inner surfaces of the control platform, the damping columns are attached to the switch cabinet panel, and the damping columns are made of TPE material.

[0014] The beneficial effects of the present invention are:

[0015] Through the linkage formed between the constraint platform 1, the constraint platform 2 and the constraint platform 4 and the abutment of the constraint platform 3, multiple sides of the switch cabinet panel can be tightened at the same time, with high tightening efficiency and guaranteed tightening firmness. By changing the position of the variable platform 2, the variable distance of the constraint platform 4 during the tightening operation can be changed to tighten switch cabinet panels of various specifications, adapt to the tightening of switch cabinets of various specifications and panels of various specifications, without repeatedly disassembling and assembling the cabinet panels, simplifying the operation and indirectly improving the efficiency of subsequent laser drilling;

[0016] The gas in the inflatable bag is discharged from the pneumatic nozzle at high speed, and the waste material remaining on the top of the carrier is impacted and cleaned by the gas, so as to avoid the waste material causing the carrier to be uneven during fastening, which in turn causes the subsequent switch cabinet panel to be placed unsteadily or even tilted, and avoids the punching position on the switch cabinet panel to be slightly deviated or tilted, thus ensuring the accuracy of subsequent laser drilling;

[0017] By dissipating heat from the switch cabinet panels after laser drilling, the temperature of the switch cabinet panels themselves is effectively reduced, making it easier to transport and store the switch cabinet panels.

[0033] In order to make the purpose, technical solution and advantages of the technical solution of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of specific embodiments of the present invention. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1 and Figure 2The embodiment of the present invention provides a switch cabinet body punching device, comprising a fixing frame 1, a servo motor 2 is installed in the middle of the outer surface of the fixing frame 1, a ball screw 3 is installed at the output end of the servo motor 2, a laser adjustment platform 4 is installed on the outer surface of the ball screw 3, a pair of servo motors 5 are installed on the outer surface of the laser adjustment platform 4 in a mirror-symmetrical manner, a ball screw 6 is installed at the output end of the pair of servo motors 5, a laser transmitting head 7 is installed on the outer surface of the pair of ball screws 6, a pair of guide columns 8 are installed on the inner surface of the fixing frame 1 in a mirror-symmetrical manner, the pair of guide columns 8 pass through the laser adjustment platform 4, and a cabinet plate fastening component 9 is installed at the lower end of the fixing frame 1;

[0035] When drilling holes in the switch cabinet panel 92, the servo motor 2 is controlled to drive the ball screw 3 to rotate through the output end on one side thereof. Under the guidance of the guide column 8, the laser adjustment table 4 is longitudinally displaced, and then the laser transmitting head 7 is longitudinally displaced. A pair of servo motors 25 are controlled to work synchronously. A pair of servo motors 25 both drive the ball screw 26 to rotate through the output end on one side thereof, and the laser transmitting head 7 is laterally displaced. The precise position of the laser transmitting head 7 is adjusted, and the laser emitted by the laser transmitting head 7 is irradiated on the switch cabinet panel 92 to realize laser drilling.

[0036] Reference Figure 3-Figure 6 The panel fastening assembly 9 comprises a bearing platform 91, a pair of switch cabinet panels 92 to be fastened are placed on the top of the bearing platform 91, and a constraint platform 1 93, a constraint platform 3 95 and a constraint platform 4 96 are arranged on the top of the bearing platform 91, the constraint platform 1 93 and the constraint platform 3 95 are arranged face to face with each other, and the constraint platform 3 95 faces the constraint platform 2 94 arranged on the top of the bearing platform 91, and an electric push rod 97 is arranged in the middle of the top of the bearing platform 91, and the driving part of the electric push rod 97 is connected to the constraint platform 1 93, and the outer surface of the constraint platform 4 96 is screwed with a linkage rod 1 98 and a linkage rod 2 911, and the linkage rod 1 99 is connected to the linkage rod 2 911. One end of 8 is screwed to the variable platform 99, and the other end of the linkage rod 911 is screwed to the variable platform 912. An adjustment component is installed between the variable platform 912 and the bearing platform 91. A connecting rod 910 is installed between the variable platform 99 and the constraint platform 93. A guide seat 9102 is installed at the bottom of the variable platform 99. The guide seat 9102 is movably connected to a guide port 9101 reserved at the outer edge of the top of the bearing platform 91. The adjustment component includes a tensioning screw 913 that passes through and rotates on the top of the variable platform 912. The tensioning screw 913 is threadedly connected to a docking port 914, and the docking port 914 is arranged in a mirror-symmetrical manner.

[0037] During actual operation, first place the switch cabinet panel 92 on the corresponding area at the top of the bearing platform 91, and then control the electric push rod 97 to drive the first restraint platform 93 to change through the driving part at one end thereof. During the change of the first restraint platform 93, the connecting rod 910 on its outer surface is used to traction the first moving platform 99 to change together (at this moment, the guiding seat 9102 at the bottom of the first moving platform 99 displaces in the guiding port 9101 to prevent the trajectory of the first moving platform 99 from being misaligned during displacement). During the change of the first moving platform 99, the first linkage rod 98 and the second linkage rod 911 are driven to rotate, and then the first linkage rod 98 and the second linkage rod 911 traction the fourth restraint platform 96 towards the central area until the first restraint platform 93, a pair of fourth restraint platforms 96 and the third restraint platform 95 simultaneously fasten the switch cabinet panel 92 from multiple directions to enhance the stability.

[0038] For switch cabinet panels 92 of multiple specifications, the operator first unscrews the tension screw 913 to disassemble the second moving platform 912 from the bearing platform 91, then traction the second moving platform 912 to the corresponding area, and finally pass the tension screw 913 through the second moving platform 912 and screw it into the docking port 914 to complete the fastening of the second moving platform 912. Under the above steps, adjust the starting point of the second moving platform 912, and then adjust the displacement distance of the fourth restraint platform 96 during fastening so as to fasten switch cabinet panels 92 of various specifications.

[0039] Refer to Figure 9-12 , a pneumatic nozzle 925 for removing waste materials on the top of the bearing platform 91 is arranged on the outer surface of the connecting rod 910. The pneumatic nozzle 925 is connected to each other through a silicone channel 927 and an air bag 926. The air bag 926 is arranged between a pair of first restraint platforms 93. When the air bag 926 contracts, air is introduced by the pneumatic nozzle 925. Damping columns 915 arranged at equal intervals are arranged on the inner surface of the fourth restraint platform 96. The damping columns 915 are in contact with the switch cabinet panel 92, and the damping columns 915 are made of TPE material. The vertical two ends of the damping columns 915 are screwed to the displacement platform 916. The damping columns 915 are movably connected to the fourth restraint platform 96. A spiral beryllium copper wire 917 is arranged between the displacement platform 916 and the inner surface of the fourth restraint platform 96.

[0040] During the tightening period, 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 vertical ends to change on the surface of the constraint platform 96, and then drives the displacement platform 916 to compress the spiral beryllium copper wire 917. The deformation of the spiral beryllium copper wire 917 plays a role of decompression protection to prevent damage to the switch cabinet panel 92. When the laser drilling of the switch cabinet panel 92 is completed, the electric push rod 97 retracts to release all the tightening states. At this time, the electric push rod 97 pulls a pair of constraint platforms 93 close to each other, and then allows the constraint platform 93 to compress the inflatable bag 926, and then allows the gas in the inflatable bag 926 to be discharged from the pneumatic nozzle 925 at high speed through the silicone channel 927. The gas impacts and cleans the waste remaining on the top of the carrier platform 91 to ensure the subsequent tightening operation.

[0041] Reference Figure 3 , Figure 7 and Figure 8 A switching platform 918 is installed on the top of the carrier 91. The switching platform 918 is made of aluminum sheet, and the area where the switching platform 918 is located coincides with the area where the switch cabinet panel 92 is placed. An exchange channel 919 for dissipating heat from the switch cabinet panel 92 is installed inside the carrier 91. The exchange channel 919 is curved, and a circulation component for repeatedly dissipating heat from the exchange channel 919 is installed on the top of the carrier 91. The circulation component includes a rotating container 920 installed on the top of the carrier 91, the exchange channel 919 and the rotating The containers 920 are connected to each other, the rotating container 920 is filled with cold water, a chiller 921 for dissipating the cold water after use is installed inside the rotating container 920, and a reciprocating plate 922 is movably installed inside the rotating container 920. The reciprocating plate 922 is connected to the constraint platform three 95 via the supporting column 923 on its outer surface, the supporting column 923 passes through the constraint platform two 94 and is movably connected to each other, and a spiral beryllium copper wire two 924 for pulling it back to its original position is installed on the outer surface of the supporting column 923.

[0042] When the tightening is completed, the switch cabinet plate 92 presses the constraint platform 3 95, and then the constraint platform 3 95 pulls the reciprocating plate 922 to move in the rotary container 920 with the cooperation of the bearing column 923, and presses the cold water in the rotary container 920 into the exchange channel 919, and uses the cold water to enhance the heat dissipation performance of the exchange channel 919 (through the exchange platform 918 and the exchange channel 919 to cooperate to achieve heat exchange, and dissipate heat for the switch cabinet plate 92 during laser drilling). After the laser drilling is completed, the switch cabinet plate 92 is released from the tightening. At this time, with the cooperation of the spiral beryllium copper wire 2 924, the bearing column 923 pulls the reciprocating plate 922 to move in the reverse direction, and then the air pressure in the rotary container 920 becomes smaller. With the cooperation of the pressure difference, the cold water in the exchange channel 919 is pumped back into the rotary container 920. At this time, the cold water is deheated with the help of the chiller 921 in the rotary container 920 to ensure its subsequent deheating function.

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.
