Description

Technical Field

[0001] The invention belongs to the technical field of distribution box processing, and specifically refers to an internal drilling positioning machine for a distribution box. Background Art

[0002] A distribution box (also called a distribution panel or distribution cabinet) is an electrical device used in a power system to distribute electrical energy, protect circuits, and control the flow of electricity to various electrical devices. Distribution boxes are usually used in residential, commercial buildings, industrial facilities, etc., and they undertake the functions of power distribution and electrical protection.

[0003] Drilling holes in distribution boxes is a common operation during the installation process. It is mainly used to connect cables, lines or for ventilation purposes. The drilling process requires special attention to safety and precision to avoid damage to the distribution box structure and electrical equipment, while ensuring the safety of the lines and the normal operation of the system. In the cutting stage of the distribution box, pre-drilling is usually not performed, mainly because the focus of the cutting stage is to cut the material of the distribution box casing (such as metal plates or plastic plates) into the required shape and size.

[0004] Usually, before drilling, it is best to mark the hole position and measure to ensure that the hole position and size meet the requirements. In addition, since distribution boxes are often used in complex and harsh environments, if the drilling position is marked incorrectly, surrounding water, dust or other pollutants will enter the distribution box, eventually causing short circuits in the components inside the distribution box due to the accumulation of pollutants. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a drilling and positioning machine inside a distribution box, which at least partially solves the above problem.

[0006] The technical solution adopted by the present invention is as follows: The present invention proposes a distribution box internal drilling positioning machine, comprising a positioning component and a lifting component, wherein the positioning component is arranged at the lower part of the lifting component; The positioning assembly is used to align the cables and drill bits on both sides of the distribution box. The positioning assembly includes a first clamping assembly and a second clamping assembly. The first clamping assembly is used to clamp and position the cables, and the second clamping assembly is used to clamp and position the drill bits. The first clamping assembly and the second clamping assembly are symmetrically arranged on both sides of the distribution box. The lifting assembly is used to lift the positioning assembly and bring the positioning assembly close to the distribution box. The lifting assembly is arranged on the upper part of the first clamping assembly and the second clamping assembly. The lifting assembly includes two groups of sliding columns, a lifting platform and a screw. The lifting platform is movably connected between the two groups of sliding columns, and the screw is arranged at the rear of the lifting platform.

[0007] Furthermore, the first clamping assembly and the second clamping assembly both include a base frame, a top mounting plate, a sliding base, a clamping strip, an intermediate fixed ring, a support column and a movable ring. The base frame is circular, and the top mounting plate is fixedly connected to the upper portion of the base frame. A plurality of groups of sliding bases are arranged in a ring at equal intervals at the front of the base frame, and a clamping strip is fixedly connected to the front of each group of sliding bases. A middle fixed ring is fixedly connected to the lower portion of the clamping strip, and a plurality of groups of support columns are arranged in a ring at equal intervals at the front of the middle fixed ring, and the movable ring is fixedly connected to the front of the plurality of groups of support columns.

[0008] Furthermore, the base frame is provided with a hollow area, and the hollow area runs through the base frame. A sliding groove is provided in the middle of each group of the sliding bases. There are multiple groups of movable grooves arranged in a ring shape with equal intervals on the middle fixed ring. The number of groups of the movable grooves is the same as the number of groups of the sliding bases, and the movable grooves are arc-shaped.

[0009] Furthermore, each group of the slide grooves is movably connected to a movable column, the front of the movable column is fixedly connected to a connecting arm, the lower part of the connecting arm is provided with a limiting column, the upper part of the connecting arm is fixedly connected to a rotating shaft, and the front part of the connecting arm is fixedly connected to a clamping block.

[0010] Furthermore, the limiting column is movably connected to the movable groove, and the rotating shaft is movably connected to the movable ring.

[0011] Furthermore, the first clamping assembly and the second clamping assembly further include a linkage base and an operating rod, the linkage base is fixedly connected to the movable ring, and the front part of the linkage base is fixedly connected to the operating rod.

[0012] Furthermore, the positioning assembly also includes a linkage rod, a lifting base and a fixed slide rod, the fixed slide rod is movably connected to the upper part of each group of top mounting plates, the lifting base is fixedly connected to the middle part of the fixed slide rod, and the linkage rod is fixedly connected between the two groups of operating rods.

[0013] Furthermore, an installation area is provided between the middle fixed ring and the movable ring, and the installation area passes through the middle fixed ring and the movable ring.

[0014] Furthermore, the lifting assembly also includes a motor, a base plate, a sliding rod and a fixing module. The motor is fixedly connected to the lower part of the base plate, the two groups of sliding columns are fixedly connected to the front part of the base plate, the rear part of the base plate is symmetrically provided with two groups of sliding rods, the lifting platform and the two groups of sliding rods are movably connected, and the fixing module is arranged on the top of the two groups of sliding rods and screw rods.

[0015] Furthermore, the lifting base is fixedly connected to the lower part of the lifting platform.

[0016] The beneficial effects achieved by the present invention using the above structure are as follows: (1) After manually operating the operating lever on the first clamping assembly, the linkage rod is controlled by the operating lever on the first clamping assembly, driving the operating lever on the second clamping assembly to move, thereby clamping the drill bit at the center of the middle fixed ring, movable ring and base frame on the second clamping assembly. The middle fixed ring, movable ring and base frame on the first clamping assembly and the second clamping assembly are all concentric. At this time, the cable and drill bit clamped together are at the same position inside and outside the distribution box, that is, the drill bit passes through the distribution box and is the cable, which can fully ensure that the drill hole can be accurately positioned.

[0017] (2) By accurately positioning the drill hole, it can be ensured that the drill hole will not affect the normal operation of the electrical equipment inside the distribution box or the strength of the structure. At this time, the first clamping assembly and the second clamping assembly can clamp the cable and the drill bit of the same diameter when working. At this time, the drill bit can be temporarily stopped, and the sharp corner on the top of the drill bit can be used to mark the specific position of the drill hole. Afterwards, after drilling with a drill bit of the same diameter as the cable, it can be ensured that the drill hole will not be too large to affect the normal operation of the electrical equipment inside the distribution box or the strength of the structure.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a distribution box internal drilling positioning machine, comprising a positioning component 2 and a lifting component 3, wherein the positioning component 2 is arranged at the lower part of the lifting component 3; The positioning assembly 2 is used to align the cables 4 and the drill bit 5 on both sides of the distribution box 1. The positioning assembly 2 includes a first clamping assembly 21 and a second clamping assembly 22. The first clamping assembly 21 is used to clamp and position the cable 4, and the second clamping assembly 22 is used to clamp and position the drill bit 5. The first clamping assembly 21 and the second clamping assembly 22 are symmetrically arranged on both sides of the distribution box 1. The lifting assembly 3 is used to lift the positioning assembly 2 and make the positioning assembly 2 close to the distribution box 1. The lifting assembly 3 is arranged on the upper part of the first clamping assembly 21 and the second clamping assembly 22. The lifting assembly 3 includes two groups of sliding columns 303, a lifting platform 304 and a screw 306. The lifting platform 304 is movably connected between the two groups of sliding columns 303, and the screw 306 is arranged at the rear of the lifting platform 304.

[0024] like Figure 4 and Figure 5As shown, the first clamping assembly 21 and the second clamping assembly 22 both include a base frame 201, a top mounting plate 202, a sliding base 203, a clamping strip 206, an intermediate fixed ring 211, a support column 212 and a movable ring 213. The base frame 201 is circular, and the top mounting plate 202 is fixedly connected to the upper portion of the base frame 201. A plurality of groups of sliding bases 203 are arranged in an annular pattern at equal intervals at the front of the base frame 201. A clamping strip 206 is fixedly connected to the front of each group of sliding bases 203. An intermediate fixed ring 211 is fixedly connected to the lower portion of the clamping strip 206. A plurality of groups of support columns 212 are arranged in an annular pattern at equal intervals at the front of the intermediate fixed ring 211. The movable ring 213 is fixedly connected to the front of the plurality of groups of support columns 212.

[0025] like Figure 4 and Figure 5 As shown, the base frame 201 is provided with a hollow area 205, and the hollow area 205 passes through the base frame 201. A sliding groove 204 is provided in the middle of each group of the sliding bases 203. A plurality of groups of movable grooves 216 are arranged in an annular pattern at equal intervals on the intermediate fixed ring 211. The number of the movable grooves 216 is the same as the number of the sliding bases 203, and the movable grooves 216 are arc-shaped.

[0026] like Figure 4 and Figure 5 As shown, each group of the slide grooves 204 is movably connected to a movable column 207, the front of the movable column 207 is fixedly connected to a connecting arm 208, the lower part of the connecting arm 208 is provided with a limiting column 209, the upper part of the connecting arm 208 is fixedly connected to a rotating shaft 220, and the front part of the connecting arm 208 is fixedly connected to a clamping block 210.

[0027] like Figure 4 and Figure 5 As shown, the limiting column 209 is movably connected to the movable groove 216 , and the rotating shaft 220 is movably connected to the movable ring 213 .

[0028] like Figure 4 and Figure 5 As shown, the first clamping assembly 21 and the second clamping assembly 22 further include a linkage base 214 and an operating rod 215 . The linkage base 214 is fixedly connected to the movable ring 213 , and the front portion of the linkage base 214 is fixedly connected to the operating rod 215 .

[0029] like Figure 4 and Figure 5 As shown, the positioning assembly 2 also includes a linkage rod 217, a lifting base 218 and a fixed slide rod 221, the fixed slide rod 221 is movably connected to the upper part of each group of top mounting plates 202, the lifting base 218 is fixedly connected to the middle part of the fixed slide rod 221, and the linkage rod 217 is fixedly connected between the two groups of operating rods 215.

[0030] like Figure 4 and Figure 5 As shown, a mounting area 219 is provided between the middle fixed ring 211 and the movable ring 213 , and the mounting area 219 passes through the middle fixed ring 211 and the movable ring 213 .

[0031] In this embodiment, firstly, because an installation area 219 is provided between the middle fixed ring 211 and the movable ring 213, and the installation area 219 passes through the middle fixed ring 211 and the movable ring 213, when the cable 4 is placed in the installation area 219, the cable 4 can pass through the installation area 219 and reach the base frame 201, and a hollow area 205 is provided in the middle of the base frame 201, and the hollow area 205 passes through the base frame 201, and finally the cable 4 can pass through the hollow area 205 and finally reach the distribution box 1, and the middle fixed ring 211, the movable ring 213 and the base frame 201 are concentric circles.

[0032] When the cable 4 finally reaches the distribution box 1, the operating rod 215 on the first clamping assembly 21 can be operated to rotate the operating rod 215 with the cable 4 as the center, and the rear part of the operating rod 215 is fixedly connected with the linkage base 214. When the operating rod 215 is rotated with the cable 4 as the center, the linkage base 214 will be driven to rotate with the cable 4 as the center, and the rear part of the linkage base 214 is fixedly connected to the movable ring 213. When the linkage base 214 rotates with the cable 4 as the center, the movable ring 213 will eventually rotate with the cable 4 as the center.

[0033] When the movable ring 213 rotates with the cable 4 as the center, since the rotating shaft 220 is movably connected to the movable ring 213, the displacement of the movable ring 213 will cause the rotating shaft 220 to move with itself as the center. The upper part of the connecting arm 208 is fixed with the rotating shaft 220. When the rotating shaft 220 moves with itself as the center, it will drive the connecting arm 208 to rotate with the rotating shaft 220.

[0034] Because a limit column 209 is provided at the lower part of the connecting arm 208, the limit column 209 is movably connected to the movable groove 216, and the movable groove 216 is arc-shaped, when the connecting arm 208 rotates with the rotating shaft 220, the limit column 209 at the lower part of the connecting arm 208 will slide inside the movable groove 216, and the sliding trajectory of the limit column 209 is to make a small range of circular motion along the arc-shaped movable groove 216, and the function of the movable groove 216 is to limit the movable trajectory of the limit column 209, thereby limiting the movement trajectory of the connecting arm 208.

[0035] When the limiting column 209 slides inside the movable groove 216, the connecting arm 208 will inevitably gradually approach the center of the middle fixed ring 211 and the movable ring 213. Because the movable column 207 is connected to the rear of the connecting arm 208, and the movable column 207 is movably connected to the inside of the slide groove 204, when the connecting arm 208 moves toward the center of the middle fixed ring 211 and the movable ring 213, the movable column 207 at its rear will slide in the slide groove 204, and the slide groove 204 can limit the movable column 207 to only a unidirectional movement up and down, thereby ensuring that the connecting arm 208 will not deviate left or right when moving toward the center of the middle fixed ring 211 and the movable ring 213.

[0036] A clamping block 210 is fixedly connected to the front end of the connecting arm 208. When the cable 4 is placed in the installation area 219 and the operating lever 215 is used, the middle fixed ring 211 is rotated at the lower part of the clamping strip 206 by the external force, thereby driving other parts to move according to the above-mentioned movement estimate. In addition, there are multiple groups of sliding bases 203 arranged in a ring shape with equal intervals in the front part of the base frame 201. The number of groups of movable grooves 216 is the same as the number of groups of the sliding bases 203. A sliding groove 204 is provided in the middle of each group of sliding bases 203. At this time, multiple groups of parts work simultaneously according to the above-mentioned movement process, and finally the cable 4 is clamped at the center of the middle fixed ring 211, the movable ring 213 and the base frame 201.

[0037] The positioning assembly 2 includes a first clamping assembly 21 and a second clamping assembly 22. When the first clamping assembly 21 is used to clamp and position the cable 4, the second clamping assembly 22 is used to clamp and position the drill bit 5. The first clamping assembly 21 and the second clamping assembly 22 are linked via a linkage rod 217.

[0038] When the operating rod 215 on the first clamping component 21 is manually operated, the linkage rod 217 is controlled by the operating rod 215 on the first clamping component 21, thereby driving the operating rod 215 on the second clamping component 22 to move, so that the drill bit 5 is clamped at the center of the intermediate fixed ring 211, the movable ring 213 and the base frame 201 on the second clamping component 22. At this time, the intermediate fixed ring 211, the movable ring 213 and the base frame 201 on the first clamping component 21 and the second clamping component 22 are all concentric. At this time, the cable 4 and the drill bit 5 clamped together are at the same position inside and outside the distribution box 1, that is, the drill bit 5 passes through the distribution box 1 and is the cable 4. At this time, it can be fully guaranteed that the drill hole can be accurately positioned.

[0039] As the drilling hole is accurately positioned, it can be ensured that the drilling hole will not affect the normal operation of the electrical equipment inside the distribution box 1 or the structural strength. At this time, the first clamping component 21 and the second clamping component 22 can clamp the cable 4 and the drill bit 5 of the same diameter when working. At this time, the drill bit 5 can be temporarily stopped, and the sharp corner on the top of the drill bit 5 can be used to carve the specific position of the drilling hole. Afterwards, after drilling with the drill bit 5 of the same diameter as the cable 4, it can be ensured that the drilling hole will not affect the normal operation of the electrical equipment inside the distribution box 1 or the structural strength due to being too large.

[0040] like Figure 3 and Figure 5 As shown, the lifting assembly 3 also includes a motor 301, a base plate 302, a sliding rod 305 and a fixing module 307. The motor 301 is fixedly connected to the lower part of the base plate 302, the two groups of sliding columns 303 are fixedly connected to the front part of the base plate 302, the rear part of the base plate 302 is symmetrically provided with two groups of sliding rods 305, the lifting platform 304 and the two groups of sliding rods 305 are movably connected, and the fixing module 307 is arranged on the top of the two groups of sliding rods 305 and the screw 306.

[0041] like Figure 3 and Figure 5 As shown, the lifting base 218 is fixedly connected to the lower part of the lifting platform 304 .

[0042] In this embodiment, first, the front part of the motor 301 is connected to a screw 306. When the motor 301 rotates, the screw 306 starts to rotate. After the screw 306 rotates, the lifting platform 304 can be raised or lowered through the engagement between the threads. The lifting base 218 is fixedly connected to the lower part of the lifting platform 304. When the lifting platform 304 rises or falls, it can drive the lifting base 218 to rise or fall, and then drive the positioning component 2 to rise or fall.

[0043] When the positioning assembly 2 is lowered to the same height as the distribution box 1, since the fixed slide bar 221 is movably connected to the upper part of each group of top mounting plates 202, the position of the mounting plate 202 on the fixed slide bar 221 can be adjusted at this time, thereby adjusting the distance between the first clamping assembly 21 and the second clamping assembly 22, so that the cable 4 and the drill bit 5 can be easily installed.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

[0046] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
