Through the cooperation of multiple sets of motors, the drill bit is driven to drill holes on the top of the distribution box. No manual operation is required, saving time and effort. Through the cooperation of springs and pull wires, a collection frame is set to facilitate the collection of debris in the distribution box and the resetting of the drill bit, thereby improving work efficiency and facilitating wide use.

[0004] However, the above patent still has the following shortcomings: the processing process of the electric control box body and the distribution box body is the same. When the use environment and use needs are different, the types and quantities of electrical components installed inside the box are different. Therefore, it is impossible to make holes on the sheet metal raw materials. Holes can only be drilled according to specific installation needs when the box is formed and assembled. At this time, the electrical components are mostly installed on the side walls of the box. Installers now use hand-held electric drills to drill holes, but they are easy to slip during the drilling process, which will not only cause scratches on the inner wall of the box, but also affect the accuracy of the drilling position. Therefore, it is necessary to design a box drilling auxiliary device. Utility Model Content

DETAILED DESCRIPTION

[0025] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0027] like Figure 1-5As shown, a box drilling auxiliary device is characterized in that it includes: a mounting plate 1, a plurality of suction cups 2 mounted on the mounting plate 1 and located on the same side of the mounting plate 1, a tube body 3 whose axis is perpendicular to the plane where the mounting plate 1 is located and fixedly mounted on the mounting plate 1 on the side away from the suction cup 2, a sleeve 4 slidably connected to the inner wall of the tube body 3 coaxially, a mounting sleeve 5 mounted on the inner wall of the first sleeve 4 coaxially through a bearing, a positioning sleeve 6 for a drill bit to pass through and coaxially mounted inside the mounting sleeve 5 through a plurality of mounting bolts, and an elastic member 7 mounted on the tube body 3 for pushing the sleeve 4 to slide away from the mounting plate 1, a pair of spiral positioning protrusions 8 evenly distributed in the circumferential direction protruding from the inner wall of the positioning sleeve 6, and a circular through groove for a drill bit to pass through and coaxially arranged with the tube body 3 is penetrated through the mounting plate 1.

[0028] When it is necessary to drill holes on the side wall of the box, several suction cups 2 are adsorbed on the side wall of the box. The drill bit has two spiral grooves. The drill bit is inserted into the positioning sleeve 6 so that the positioning protrusion 8 is inserted into the corresponding spiral groove. After the drill bit rotates, it will drive the positioning sleeve 6 to rotate synchronously. The drill bit moves close to the side wall of the box to drill holes. The resistance caused by the rotation of the drill bit will make the positioning protrusion 8 unable to slide in the spiral groove. Therefore, the movement of the drill bit will cause the positioning sleeve 6 to move synchronously, and the sliding sleeve 4 is driven by the bearing to slide on the inner wall of the tube body 3, which can prevent the drill bit from slipping and deviating during the drilling process, thereby improving the drilling accuracy; after the drilling is completed, the drill bit is removed from the positioning sleeve 6, and the elastic member 7 will push the sliding sleeve 4 to slide in the tube body 3 to return to its original position.

[0029] Because the positioning sleeve 6 is mounted on the mounting sleeve 5 by means of a plurality of mounting bolts, after removing the plurality of mounting bolts, the positioning sleeves 6 of different specifications can be replaced to be suitable for different drill specifications.

[0030] A first coaxial annular flange 9 is protruded on the inner wall of the end of the tube body 3 that fits the mounting plate 1, and a first protective sleeve 10 arranged close to the sliding sleeve 4 is coaxially provided on the inner edge of the first annular flange 9, and a second protective sleeve 10 is coaxially fixedly connected to the sliding sleeve 4 and fits and slides with the inner wall of the first protective sleeve 10, and a rubber ring 12 is assembled at the end of the second protective sleeve away from the sliding sleeve 4 and fits and contacts with the inner wall of the first protective sleeve 10.

[0031] Metal chips will be generated during the punching process. The function of the first anti-slip sleeve 4 and the second protective sleeve is to intercept the metal chips from entering between the sliding sleeve 4 and the tube body 3, because the metal chips will be stuck between the sliding sleeve 4 and the tube body 3 and hinder the sliding of the sliding sleeve 4; the rubber ring 12 can clean the metal chips on the inner wall of the first protective sleeve 10 to prevent the metal chips from hindering the sliding of the second protective sleeve on the first protective sleeve 10.

[0032] The elastic member 7 is a spring located between the tube body 3 and the first protective sleeve 10, and the two ends of the spring are respectively in contact with the sliding sleeve 4 and the first annular flange 9. The end of the tube body 3 away from the mounting plate 1 is fixedly installed with a limit member 13 that can contact the side of the sliding sleeve 4 away from the mounting plate 1.

[0033] When the drill bit rotates and moves close to the inner wall of the box, it will drive the sliding sleeve 4 to move on the inner wall of the tube body 3, and the spring will be further compressed; after the drilling is completed, the drill bit is moved out of the positioning sleeve 6, and the spring will push the sliding sleeve 4 to slide until it contacts the limit piece 13.

[0034] A support tube 14 coaxially arranged with the tube body 3 is fixedly mounted on the side of the mounting plate 1 away from the tube body 3 .

[0035] The support tube 14 plays a supporting role when drilling, preventing the portion of the mounting plate 1 connected to the tube body 3 from being sunken and deformed during long-term use.

[0036] The side wall of the support tube 14 away from the mounting plate 1 is recessed with a plurality of discharge slots 15 evenly distributed along the circumferential direction.

[0037] Metal chips generated during the drilling process can be discharged through the discharge slot 15 .

[0038] At least one strip-shaped convex strip 16 arranged in the same length direction protrudes from the inner wall of the tube body 3 , and a strip-shaped groove matching the strip-shaped convex strip 16 is recessed on the outer wall of the sliding sleeve 4 .

[0039] The end of the positioning sleeve 6 away from the mounting plate 1 protrudes with a coaxial second annular flange 17 that can fit the end of the mounting sleeve 5 away from the mounting plate 1 , and the mounting bolt passes through the second annular flange 17 and is installed on the mounting sleeve 5 .

[0040] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0041] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0042] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
