Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a method and a device for positioning and opening a hole for an electrical indicator light switch. Background Art

[0002] At present, the design of some electrical equipment panels on board cannot meet the quality requirements of shipowners' on-site ship inspections. If the electrical equipment box lacks batch indicator light switches, the shipyard must immediately rectify the holes and install them in place to facilitate wiring and power supply as soon as possible.

[0003] The traditional method of drilling holes for electrical indicator light switches is: first drill a circle of holes at the installation location of the electrical indicator light switch, and then use a chisel to chisel off the excess material in the middle. Since the body of the electrical equipment box is relatively thin, generally about 1.5mm thick, the impact of the chisel will cause fatal damage to the instruments on the panel of the electrical equipment box, and will also cause the body of the electrical equipment box to deform. If saw cutting is used instead of the construction method of drilling + chiseling, it is necessary to first draw the installation positioning line of the electrical indicator light switch on the electrical equipment box, and then use a saw to cut the steel plate along the installation positioning line of the electrical indicator light switch. After the steel plate is cut off, use a file to file and trim the frame, and then remove the burrs, and finally ensure that the indicator light switch is installed in place. This construction process is cumbersome and complicated, the work efficiency is low, and it is impossible to drill holes in batches, and the drilling accuracy is low. Summary of the invention

[0004] In view of this, the present invention provides a method and device for positioning and opening a hole for an electrical indicator light switch, so as to solve the problems existing in the above-mentioned background technology.

[0005] A method for positioning and opening a hole for an electrical indicator light switch, comprising the following steps:

Under the action of the baffle tightening torque, the arc-shaped blade head gradually approaches the electrical equipment box. When the arc-shaped blade head contacts the electrical equipment box, the tightening torque of the baffle is increased so that the tip of the arc-shaped blade head pierces the steel plate of the electrical equipment box. Then the baffle is continued to be rotated. Under the action of the tightening torque of the baffle, the arc-shaped blade head cuts out the electrical indicator switch positioning hole, and the cut steel plate surplus is pushed into the support cover by the arc-shaped blade head.

[0012] S6, remove the baffle, center screw, curved cutter head, support cover and support nut, and install the electrical indicator light switch on the electrical equipment box.

[0037] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.

[0038] The present invention provides a method for positioning and opening a hole of an electrical indicator light switch, which specifically comprises the following steps:

[0039] S1, drill a positioning hole on the electrical equipment box.

[0040] The positioning hole is used to determine the opening position of the electrical indicator light switch on the electrical equipment box. The size of the positioning hole matches the size of the center screw 2. The positioning hole can be set as an ordinary circular hole with a smooth inner circumference, or it can be set as a threaded hole with a threaded inner circumference. In this embodiment, the positioning hole is set as an ordinary circular hole with a smooth inner circumference.

[0041] The size of the central screw 2 matches the size of the positioning hole, and the central screw is a screw with a standard thread.

[0042] S2, the central screw rod 2 passes through the arc-shaped cutter head 3 and the positioning holes on the electrical equipment box in sequence, so that a part of the rod section of the central screw rod 2 is located inside the electrical equipment box, and the other part of the rod section is located outside the electrical equipment box.

[0043] A plurality of blade tips extend from the side edge of the arc-shaped blade head 3 facing the electrical equipment box.

[0044] Specifically, the arc-shaped cutter head 3 comprises a cutter head body 31, a first through hole 32 for the central screw 2 to pass through is formed through the center of the cutter head body 31, the first through hole 32 is a common round hole with a smooth inner circumference, and the size of the first through hole 32 matches the size of the central screw 2. At least one groove is provided on the side of the cutter head body 31 facing the electrical equipment box, each groove edge of the groove is formed with an inwardly concave arc-shaped blade, and the intersection of two adjacent arc-shaped blades forms a blade tip.

[0045] Two grooves are provided on the side of the cutter body 31 facing the electrical equipment box. The grooves can be set as spherical grooves or other shapes, but the groove surface needs to gradually transition to connect with the side edge of the cutter body 31, so that the arc-shaped blades located on each groove edge of the groove are exactly located on each side of the cutter body 31.

[0046] In this embodiment, the groove on the side of the cutter body 31 facing the electrical equipment box is a semi-spherical groove, and two adjacent semi-spherical grooves are provided on the side. Therefore, a total of six blade tips are formed on the side of the cutter body 31 facing the electrical equipment box, and the blade tips are used to pierce the steel plate to facilitate the arc-shaped blade to open a hole.

[0052] The baffle plate 1 is provided with a threaded hole, and the baffle plate 1 is fixed on the central screw 2 to apply a torque to the arc-shaped cutter head 3 so that the arc-shaped cutter head 3 cuts off the steel plate at the position covered by the arc-shaped cutter head 3. In this embodiment, the baffle plate 1 is a hexagonal nut.

[0053] S4, screwing the support nut 5 in a direction toward the arc-shaped blade head 3 until the support cover 4 contacts the inner side surface of the electrical equipment box.

The central screw rod 2 passes through the baffle plate 1, the arc-shaped cutter head 3, the support cover body 4 and the support nut 5 in sequence. The arc-shaped cutter head 3 is located on the outside of the electrical equipment box, and the support cover body 4 is located on the inside of the electrical equipment box and is tightened by the support nut 5 so as to contact the inner side surface of the electrical equipment box.

[0057] A first through hole 32 is formed in the center of the arc-shaped blade head 3 for the center screw 2 to pass through, and at least one groove is formed on the side of the arc-shaped blade head 3 facing the electrical equipment box.
