Description

Technical Field

[0001] This utility model relates to the field of electrical equipment processing technology, specifically a drilling device for mechanical electrical equipment. Background Technology

[0002] Drilling is an indispensable process in the production and maintenance of mechanical and electrical equipment. Whether it's machining mounting holes for the equipment casing or creating wiring holes for internal circuits, drilling is necessary to achieve precise assembly and functional connection of components. When drilling holes in distribution cabinets, since these cabinets are usually pre-formed enclosures with fixed internal space layouts and casing strength designs, it's difficult to use large machining equipment for drilling. Therefore, small manual drilling tools are often used.

[0003] However, in existing small manual drilling machines, the direction and force applied by the operator directly affect the drilling trajectory during manual operation, easily leading to deviation or tilting, causing hole position deviations to exceed tolerance ranges. Furthermore, the lack of reliable positioning aids makes it impossible to effectively ensure the perpendicularity and concentricity of holes when drilling in multi-layer boards or thick plates, resulting in problems such as inaccurate insertion of installation components and difficulties in wiring.

[0004] Therefore, a drilling device for mechanical and electrical equipment is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drilling device for mechanical and electrical equipment, which has the advantages of ensuring the verticality and concentricity of the hole and solves the problem of hole position deviation that is easy to occur in existing tools.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for mechanical and electrical equipment, comprising a transmission assembly, an opening assembly mounted on the transmission assembly, and a driving assembly mounted on the transmission assembly, wherein the driving assembly drives the opening assembly to make a hole through the transmission assembly;

[0007] The hole-opening assembly includes a nut post, a connecting bracket is fixedly installed on the outer side of the bottom of the nut post, an anti-slip ring is embedded in the connecting bracket, an installation groove is opened at the bottom of the nut post, and a hole opener is inserted and installed at the bottom of the nut post through the installation groove.

[0008] Preferably, the transmission assembly includes a mounting bracket with a screw passing through its bottom. The screw is rotatably mounted to the mounting bracket, and a second bevel gear is fixedly mounted on the top of the screw passing through the mounting bracket.

[0009] A first bevel gear is rotatably mounted on the mounting bracket, and a protective frame is fixedly mounted on the mounting bracket outside the first bevel gear.

[0010] A first grip is fixedly installed on the top of the mounting bracket, a grip frame is fixedly installed on one side of the mounting bracket, and a connecting rod is fixedly installed on the other side of the mounting bracket. The connecting rod is used to connect the drive assembly.

[0011] In the design, the bottom of the mounting bracket of the transmission component rotates and mounts the screw to fix the second bevel gear. Through the meshing transmission of the first bevel gear and the second bevel gear, the power transmission from the drive component to the opening component is realized.

[0012] The protective frame on the outside of the mounting bracket serves to protect the gear meshing structure and prevent external debris from interfering with the transmission.

[0013] The first grip handle and grip frame facilitate stable handling of the device by the operator, while the connecting rod is used to rigidly connect the drive components, ensuring no shaking during transmission.

[0014] Preferably, the drive assembly includes an end face gear disk with an opening at its center, and the end face gear disk is rotatably mounted to the connecting rod through the opening at its center.

[0015] The teeth on the end face gear disk mesh with the first bevel gear and the second bevel gear.

[0016] A second grip is mounted on the end face gear disk via a mounting rod. The second grip is used to rotate the end face gear disk along the connecting rod.

[0017] In the design, the end face gear disk of the drive component is rotatably mounted to the connecting rod through a central opening. Its end face teeth mesh with the first bevel gear and the second bevel gear, realizing the conversion from circular rotation to vertical transmission.

[0018] The second grip is fixed to the end face gear plate by the mounting rod. The operator can rotate the end face gear plate along the connecting rod by holding the second grip, which has the advantages of labor-saving and uniform speed drive, avoiding the drilling tilt caused by uneven manual force application.

[0019] Preferably, the minor diameter of the internal thread on the nut post is smaller than the inner diameter of the mounting groove. The nut post is installed at the bottom of the screw through the internal thread. The nut post is designed with neodymium magnet material and can be attracted to the hole opener.

[0020] In the design, the minor diameter of the internal thread of the nut column is smaller than the inner diameter of the mounting groove, so that the hole opener forms a limiting structure after being inserted and installed to prevent axial fall-off. At the same time, when the screw moves down, it can push the hole opener to move down to perform hole opening operations.

[0021] The nut post is made of neodymium magnet material and can be attracted to the hole opener, which realizes quick disassembly and coaxial positioning of the hole opener. It has the characteristics of convenient replacement and precise positioning, and can adapt to the processing needs of different hole diameters.

[0022] Preferably, the bottom surface of the anti-slip ring has radially formed grooves, and the anti-slip ring is made of soft rubber material.

[0023] In the design, the radial grooves on the bottom surface of the anti-slip ring increase the contact friction with the surface of the distribution cabinet to be drilled. The soft rubber material has elastic deformation capability, which can closely fit the surface of the board with different roughness, effectively preventing the device from sliding during drilling and improving the stability of the drilling process.

[0024] Preferably, a positioning cone is provided at the center of the top of the inner side of the hole opener, the bottom height of the positioning cone is lower than the bottom height of the anti-slip ring, the hole opener is coaxially arranged with the nut column, and the hole opener is connected to the nut column key through the mounting groove.

[0025] In the design, the bottom height of the positioning cone on the inside of the hole opener is lower than the bottom height of the anti-slip ring, ensuring that the positioning cone contacts the surface of the distribution cabinet to be opened before drilling to form an initial positioning point, guiding the hole opener to cut vertically.

[0026] The hole opener and the nut post are set coaxially, which structurally ensures that the center line of the hole is consistent with the axis of the screw. It has the core function of controlling the verticality and concentricity of the hole, and solves the problem of skewing when opening holes in multi-layer boards.

[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0028] This utility model achieves the effect of ensuring the verticality and concentricity of the hole and solving the problem of hole position deviation in existing tools by setting a nut column, connecting bracket, anti-slip ring, mounting groove and hole opener.

[0029] An anti-slip ring is embedded in the connecting bracket on the outer side of the bottom of the nut column. Its soft material fits tightly with the surface of the workpiece to form a stable support surface, preventing the device from tilting or shifting during drilling.

[0030] The hole opener is installed coaxially with the nut column through the mounting slot, ensuring that the center line of the hole opener is consistent with the axis of the nut column. With the vertical guide structure of the transmission component, the hole opening process is precisely advanced along the fixed axis, eliminating the trajectory deviation caused by uneven manual force application from the structure, and effectively ensuring the verticality and concentricity of the hole.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a drilling device for mechanical and electrical equipment, including a transmission component 2, an opening component 1 installed on the transmission component 2, and a driving component 3 installed on the transmission component 2. The driving component 3 drives the opening component 1 to make a hole through the transmission component 2.

[0039] The hole-opening assembly 1 includes a nut post 11, a connecting bracket 12 is fixedly installed on the outer side of the bottom of the nut post 11, an anti-slip ring 13 is embedded in the connecting bracket 12, and an installation groove 111 is opened at the bottom of the nut post 11. A hole opener 14 is inserted and installed at the bottom of the nut post 11 through the installation groove 111.

[0040] Specifically, by setting the nut post 11, connecting bracket 12, anti-slip ring 13, mounting groove 111 and hole opener 14, the verticality and concentricity of the hole are guaranteed, and the problem of hole position deviation of existing tools is solved.

[0041] An anti-slip ring 13 is embedded in the connecting bracket 12 on the outer side of the bottom of the nut column 11. Its soft material is in close contact with the surface of the workpiece to form a stable support surface, preventing the device from tilting or shifting during drilling.

[0042] The hole opener 14 is installed coaxially with the nut column 11 through the mounting groove 111, ensuring that the center line of the hole opener is consistent with the axis of the nut column. With the vertical guide structure of the transmission component, the hole opening process is precisely advanced along the fixed axis, eliminating the trajectory deviation caused by uneven manual force application from the structure, and effectively ensuring the verticality and concentricity of the hole.

[0043] Example 2

[0044] In order to achieve stable power transmission and operational control, such as Figure 2 and Figure 3 As shown, in this embodiment, the transmission assembly 2 includes a mounting frame 21, with a screw 214 passing through the bottom of the mounting frame 21. The screw 214 is rotatably mounted to the mounting frame 21, and a second bevel gear 24 is fixedly mounted on the top of the screw 214 passing through the mounting frame 21.

[0045] A first bevel gear 23 is rotatably mounted on the mounting bracket 21, and a protective bracket 211 is fixedly mounted on the mounting bracket 21 outside the first bevel gear 23;

[0046] A first grip 22 is fixedly installed on the top of the mounting bracket 21, a grip 212 is fixedly installed on one side of the mounting bracket 21, and a connecting rod 213 is fixedly installed on the other side of the mounting bracket 21. The connecting rod 213 is used to connect the drive assembly 3.

[0047] Specifically, the mounting bracket 21 of the transmission component 2 rotates to mount the screw 214 at the bottom and fixes the second bevel gear 24. Through the meshing transmission of the first bevel gear 23 and the second bevel gear 24, the power transmission from the drive component 3 to the opening component 1 is realized.

[0048] The protective frame 211 on the outside of the mounting bracket 21 serves to protect the gear meshing structure and prevent external debris from interfering with the transmission.

[0049] The first grip handle 22 and the grip frame 212 facilitate the operator to hold the device stably, while the connecting rod 213 is used to rigidly connect the drive assembly 3 to ensure that there is no shaking during the transmission process.

[0050] Furthermore, the drive assembly 3 includes an end face gear disk 31 with an opening at its center, and the end face gear disk 31 is rotatably mounted to the connecting rod 213 through the opening at its center.

[0051] The teeth on the end face gear 31 mesh with the first bevel gear 23 and the second bevel gear 24.

[0052] A second grip 321 is mounted on the end face gear disk 31 via a mounting rod 32. The second grip 321 is used to rotate the end face gear disk 31 along the connecting rod 213.

[0053] Specifically, the end face gear 31 of the drive assembly 3 is rotatably mounted to the connecting rod 213 through a central opening, and its end face teeth mesh with the first bevel gear 23 and the second bevel gear 24, realizing the conversion from ring rotation to vertical transmission;

[0054] The second grip 321 is fixed to the end face gear plate 31 by the mounting rod 32. The operator can rotate the end face gear plate 31 along the connecting rod 213 by gripping the second grip 321, which has the advantages of saving effort and driving at a uniform speed, avoiding the tilting of the drilling caused by uneven manual force application.

[0055] Example 3

[0056] To achieve quick replacement of the hole opener, anti-slip positioning, and precise hole opening, such as Figure 1 and Figure 4 As shown, in this embodiment, the minor diameter of the internal thread on the nut post 11 is smaller than the inner diameter of the mounting groove 111. The nut post 11 is installed at the bottom of the screw 214 through the internal thread. The nut post 11 is designed with neodymium magnet material and can be attracted to the hole opener 14.

[0057] Specifically, the minor diameter of the internal thread of the nut column 11 is smaller than the inner diameter of the mounting groove 111, so that the hole opener 14 forms a limiting structure after being inserted and installed to prevent axial dislodgement. At the same time, when the screw 214 moves down, it can push the hole opener 14 down to perform hole opening operations.

[0058] The nut post 11 is made of neodymium magnet material and can be attracted to the hole opener 14, which realizes the quick disassembly and coaxial positioning of the hole opener 14. It has the characteristics of convenient replacement and precise positioning, and can adapt to the processing needs of different hole diameters.

[0059] Furthermore, the bottom surface of the anti-slip ring 13 has radially arranged grooves 131, and the anti-slip ring 13 is made of soft rubber material.

[0060] Specifically, the radial grooves 131 on the bottom surface of the anti-slip ring 13 increase the contact friction with the surface of the distribution cabinet to be drilled. The soft rubber material has elastic deformation capability and can closely fit the surface of the plate with different roughness, effectively preventing the device from sliding during drilling and improving the stability of the drilling process.

[0061] Furthermore, a positioning cone 141 is provided at the center of the top of the inner side of the hole opener 14. The bottom height of the positioning cone 141 is lower than the bottom height of the anti-slip ring 13. The hole opener 14 is coaxially arranged with the nut post 11, and the hole opener 14 is keyed to the nut post 11 through the mounting groove 111.

[0062] Specifically, the bottom height of the positioning cone 141 on the inner side of the hole opener 14 is lower than the bottom height of the anti-slip ring 13, ensuring that the positioning cone 141 first contacts the surface of the distribution cabinet to be drilled before drilling to form an initial positioning point, guiding the hole opener 14 to cut vertically.

[0063] The hole punch 14 and the nut post 11 are coaxially arranged, which structurally ensures that the center line of the hole is consistent with the axis of the screw 214. It has the core function of controlling the verticality and concentricity of the hole and solves the problem of skewing when drilling holes in multilayer boards.

[0064] When using this invention, a suitable hole opener 14 is selected according to the diameter of the hole to be processed, and its top is inserted into the mounting groove 111 at the bottom of the nut post 11. Since the nut post 11 is made of neodymium magnet material, the hole opener 14 is attracted and fixed, and at the same time, the limiting structure of the mounting groove 111 prevents it from falling off axially, ensuring that the hole opener and the nut post 11 are coaxially aligned.

[0065] The device is moved to the surface of the electrical cabinet to be drilled. Because the bottom of the positioning cone 141 on the inner side of the hole saw 14 is lower than that of the anti-slip ring 13, it contacts the workpiece surface first, forming a positioning fulcrum. This guides the hole saw to be vertically aligned with the center of the preset hole. A heavy hammer strike causes the positioning cone 141 to pierce the electrical cabinet, and the bottom surface of the anti-slip ring 13 to tightly adhere to the workpiece surface. The soft rubber material and radial grooves 131 of the anti-slip ring 13 provide elastic cushioning and friction, preventing the device from sliding.

[0066] The operator holds the first grip handle 22 with one hand to ensure that the mounting bracket 21 is stable and does not wobble; with the other hand, the operator holds the second grip handle 321, ready to drive the end face gear plate 31.

[0067] By rotating the second grip 321, the end face gear 31 is driven to rotate in a ring along the connecting rod 213. The teeth of the end face gear 31 mesh with the first bevel gear 23 and the second bevel gear 24, converting the ring motion into the vertical rotational motion of the screw 214. The screw 214 drives the opening assembly 1 to feed downward through the internal thread of the nut column 11.

[0068] While maintaining the uniform rotation of the second gripping handle 321, the screw 214 moves downwards synchronously and uniformly, and the hole opener 14 cuts vertically into the workpiece under the guidance of the positioning cone 141. The anti-slip ring 13 continuously adheres to the workpiece surface, counteracting the lateral force during drilling and ensuring that the hole opener feeds precisely along the axis of the screw 214, avoiding tilting or deviation.

[0069] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
