Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinet processing devices, in particular to a drilling device for power distribution cabinet processing. Background Art

[0002] The distribution cabinet is the final equipment of the distribution system. Common metal materials in the distribution cabinet include aluminum alloy, galvanized steel plate, stainless steel, copper, etc. Among them, aluminum alloy and galvanized steel plate are relatively common materials, which have good electrical conductivity and thermal conductivity. When in use, it is necessary to set drilling holes of various apertures. When drilling, due to its low thickness, if the downward drilling pressure is too large, it will cause excessive deformation around the hole. In addition, for drilling of different apertures, it is necessary to drill at different workstations or replace different drill bits, which is more troublesome. Utility Model Content

[0016] The utility model is further described below in conjunction with the accompanying drawings:

[0017] like Figure 1-3 As shown, a drilling device for processing a power distribution cabinet is composed of a placement frame 1 and a multi-section drill bit 6;

[0018] The placing frame 1 is supported and installed with a top frame 3 through a vertical frame 2, and an electric telescopic cylinder 4 is supported and fixed on the top frame 3. The end of the telescopic rod of the electric telescopic cylinder 4 extends to the bottom of the top frame 3 and is fixedly installed with a lifting and pressing frame 7. A plurality of drive box hanging columns 8 are slidably installed on the lifting and pressing frame 7. The bottom ends of the drive box hanging columns 8 are fixedly installed with a drive box 9 arranged under the lifting and pressing frame 7. A pressure sensor 10 is installed at the bottom center of the lifting and pressing frame 7. The pressure sensor 10 is directly opposite to the drive box 9, which is convenient for the drive box 9 to press the pressure sensor 10, so as to facilitate the feedback of the pressure when drilling the distribution cabinet;

[0019] A motor 17 is fixedly mounted on the inner top of the driving box 9, and a driving shaft 15 is connected to the motor 17. The bottom end of the driving shaft 15 extends to the bottom of the driving box 9 and is connected to the multi-section drill bit 6;

[0020] A downward pressure limit column 12 is slidably installed on the lifting and lowering pressure frame 7. The downward pressure limit column 12 and the drive box suspension column 8 are both vertically arranged. A pressure frame 19 is fixedly installed on the bottom end of the downward pressure limit column 12. The pressure frame 19 is used to press the metal plate of the distribution cabinet when drilling. A compression spring 13 is sleeved on the downward pressure limit column 12 between the lifting and lowering pressure frame 7 and the pressure frame 19.

[0021] like Figure 1-3 As shown, the utility model also discloses the following more optimized specific structures:

[0022] A limit column end ring 14 is fixedly installed on the top of the downward limit column 12, and a limit column top limit end ring 11 is fixedly installed on the top of the drive box suspension column 8.

[0023] The multi-section drill bit 6 is connected from top to bottom in sequence by a top drill string 61, a middle drill string 62 and a bottom drill string 63, the column diameters of the top drill string 61, the middle drill string 62 and the bottom drill string 63 decrease in sequence, and the middle drill string 62 can be provided with multiple sections to meet different drilling requirements.

[0024] The fan blades 18 are installed on the driving shaft 15 inside the driving box 9, and a plurality of ventilation holes are provided on the box body of the driving box 9 to facilitate heat dissipation during drilling and to blow air around the hole.

[0025] The bottom support of the placement rack 1 is installed with a support leg 16, the vertical frame 2 is installed with a controller 5, and the bottom of the pressure frame 19 is installed with a ring pad 20, which is convenient for protecting the distribution cabinet.

[0026] like Figure 1-Figure 3 The drilling equipment for processing the distribution cabinet shown in the figure has a channel on the placement frame 1 to facilitate the passage of the multi-section drill bit 6. The electric telescopic cylinder 4 determines the drilling and pressing distance of the multi-section drill bit 6 through the total downward pressing stroke. The plate of the distribution cabinet is placed on the placement frame 1, and then the electric telescopic cylinder 4 is controlled to press down. The total downward pressing stroke is determined according to the drilling size requirement. The larger the drilling hole diameter, the larger the downward pressing stroke. During the pressing process, the pressing frame 19 is pressed onto the plate. After the motor is started, the bottom drill column 63 drills holes in the plate, and then the middle drill column 62 and the top drill column 61 drill holes in turn. During the pressing process, the driving box 9 presses the pressure sensor 10, and the downward pressing pressure is fed back to the controller 5, thereby controlling the downward pressing speed of the electric telescopic cylinder 4 to avoid deformation of the drill hole caused by too fast a downward pressing speed.
