Description

Technical Field

[0001] This utility model belongs to the field of signage manufacturing technology, and in particular relates to a positioning and drilling device for building signage manufacturing. Background Technology

[0002] Building signage refers to signs hung on the exterior facades of buildings to indicate building numbers. By installing building signage, a convenient information communication tool is provided for vehicles and pedestrians unfamiliar with the local area, reducing unnecessary confusion.

[0003] To facilitate the installation of building signage, drilling devices are needed to create holes at the corners of the signs during production. Research reveals that commonly available drilling devices on the market are inefficient at precisely positioning the holes within the same batch of signs, leading to discrepancies in hole placement and affecting installation. Furthermore, these devices are inefficient and slow. Therefore, there is an urgent need to improve existing positioning drilling devices and provide a new positioning drilling device for building signage production. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a positioning and drilling device for building signage production that is reasonably designed, simple in structure, accurate in drilling position, and efficient and fast in drilling, thereby solving the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning and drilling device for building signage production includes a base plate, a fixed plate fixed to the upper rear center of the base plate, and sliding grooves formed inside both the left and right ends of the base plate. Clamping components are installed in both sliding grooves. Electric telescopic rods are fixed to the upper left and right ends of the base plate. A mounting frame is fixedly connected to the telescopic end of each electric telescopic rod. A bidirectional lead screw and a horizontal shaft are mounted vertically along the inner side of the mounting frame. Rotary drilling components are symmetrically installed on the outer sides of both ends of the horizontal shaft. A drive motor is fixedly mounted on the left side wall of the mounting frame, and its output end is fixedly connected to the left end of the horizontal shaft. A servo motor is fixedly mounted on the right side wall of the mounting frame, and its output end is fixedly connected to the right end of the bidirectional lead screw. The electric telescopic rod, drive motor, and servo motor are all electrically connected to an external controller via connecting wires.

[0007] In a preferred embodiment, the clamping assembly includes a limiting rod, a movable plate, a through hole, and a vertical rod. The two limiting rods are fixed inside the slide groove and are arranged symmetrically front to back. The bottom end of the movable plate is slidably located inside the slide groove and is slidably sleeved on the outside of the limiting rod. A through hole is opened inside the bottom end of the movable plate, and a vertical rod is fixedly installed at the top end of the movable plate.

[0008] In a preferred embodiment, the two sets of rotating opening assemblies are linked by a horizontal shaft, and the outer wall of the horizontal shaft is provided with symmetrical protruding structures.

[0009] In a preferred embodiment, the rotary drilling assembly includes an L-shaped frame, a sleeve, a first bevel tooth, a drill rod, and a second bevel tooth. The top of the vertical section of the L-shaped frame is threaded onto the outside of the threaded section of the bidirectional lead screw. A sleeve is mounted on a bearing in the middle of the vertical section of the L-shaped frame. The first bevel tooth is fixedly mounted on the outside of one end of the sleeve. A drill rod is mounted on a bearing inside the horizontal section of the L-shaped frame. The top of the drill rod is fixedly connected to a second bevel tooth, which meshes with the first bevel tooth.

[0010] In a preferred embodiment, the sleeve is slidably fitted onto the outside of the horizontal shaft, and the bottom end of the drill rod is located directly above the through hole.

[0011] In a preferred embodiment, a fixing block is fixedly provided on the outer wall of the horizontal section of the L-shaped frame, and the fixing block is slidably sleeved on the outside of the vertical rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] In the solution of this utility model:

[0014] Place one end of the sign against the fixed plate, then start the servo motor to control the bidirectional lead screw to rotate, and control the two sets of rotating hole-opening components to drive the two moving plates on the left and right sides to move horizontally and move closer to each other through the vertical rod until the two moving plates contact the left and right ends of the sign respectively, so that the two drill rods are located above the left and right sides of the sign respectively, which is convenient for positioning and drilling of signs of the same batch and the same size, ensuring accurate hole positions and facilitating subsequent installation;

[0015] During the drilling process, the electric telescopic rod and drive motor are opened simultaneously. The rotating horizontal axis can drive the casing and the first bevel tooth to rotate by the symmetrical protruding structure on its outer wall. The second bevel tooth, which meshes with the first bevel tooth, can control the drill rod to rotate rapidly while moving vertically downward, which can reduce drilling resistance and achieve fast and efficient drilling.

[0023] The embodiments described below are merely some embodiments of the present invention and do not represent all embodiments consistent with the present invention. Exemplary embodiments will now be described with reference to the accompanying drawings:

[0024] like Figure 1-4 As shown, the positioning and drilling device for building signage production of this utility model includes a base plate 1, a fixed plate 2 fixed at the upper rear center of the base plate 1, and sliding grooves 3 opened inside both the left and right ends of the base plate 1. Clamping components 4 are provided in both sliding grooves 3. Electric telescopic rods 5 are fixed above both the left and right ends of the base plate 1. The telescopic ends of the electric telescopic rods 5 are fixedly connected to the mounting frame 6. A bidirectional lead screw 7 and a horizontal shaft 8 are mounted on the inner side of the mounting frame 6 along the vertical direction. Rotary opening components 9 are symmetrically installed on the outer sides of the left and right ends of the horizontal shaft 8. A drive motor 10 is fixedly installed on the left side wall of the mounting frame 6. The output end of the drive motor 10 is fixedly connected to the left end of the horizontal shaft 8. A servo motor 11 is fixedly installed on the right side wall of the mounting frame 6. The output end of the servo motor 11 is fixedly connected to the right end of the bidirectional lead screw 7. The electric telescopic rod 5, the drive motor 10, and the servo motor 11 are all electrically connected to an external controller through connecting wires.

[0025] Based on the above structure, the clamping assembly 4 includes a limiting rod 41, a movable plate 42, a through hole 43, and a vertical rod 44. The two limiting rods 41 are fixed inside the slide groove 3 and are arranged symmetrically front and back. The bottom end of the movable plate 42 is slidably located inside the slide groove 3 and is slidably sleeved on the outside of the limiting rod 41. A through hole 43 is opened inside the bottom end of the movable plate 42, and a vertical rod 44 is fixedly installed on the top end of the movable plate 42.

[0026] In this embodiment, the limiting rod 41 is used to improve the stability of the moving plate 42 during the horizontal sliding adjustment process. By controlling the left and right moving plates 42 to slide synchronously and move closer to each other, it is convenient to cooperate with the fixed plate 2 to position the marking plate and facilitate the accurate positioning of the opening hole.

[0027] Based on the above structure, the two sets of rotating opening components 9 are linked together by the horizontal axis 8, and the outer wall of the horizontal axis 8 is provided with symmetrical protruding structures.

[0028] In this embodiment, the symmetrically arranged protruding structures on the outer wall of the horizontal axis 8 facilitate the stable rotation of the sleeve 92 and the first bevel tooth 93 when the horizontal axis 8 rotates.

[0029] Based on the above structure, the rotary drilling assembly 9 includes an L-shaped frame 91, a sleeve 92, a first bevel tooth 93, a drill rod 94, and a second bevel tooth 95. The top of the vertical section of the L-shaped frame 91 is threaded onto the outside of the threaded section of the bidirectional lead screw 7. The sleeve 92 is mounted on the bearing in the middle of the vertical section of the L-shaped frame 91. The first bevel tooth 93 is fixedly mounted on the outside of one end of the sleeve 92. The drill rod 94 is mounted on the bearing inside the horizontal section of the L-shaped frame 91. The second bevel tooth 95 is fixedly connected to the top of the drill rod 94. The second bevel tooth 95 meshes with the first bevel tooth 93.

[0030] In this embodiment, since the first bevel tooth 93 meshes with the second bevel tooth 95, when the horizontal shaft 8 drives the sleeve 92 and the first bevel tooth 93 to rotate stably, it can also drive the drill rod 94 to rotate quickly and stably, thereby reducing the resistance of the drill rod 94 when drilling and achieving fast and efficient drilling.

[0031] Based on the above structure, the sleeve 92 is engaged and slidably sleeved on the outside of the horizontal shaft 8, and the bottom end of the drill rod 94 is located directly above the through hole 43.

[0032] In this embodiment, the through hole 43 facilitates the drill rod 94 to penetrate the marker plate, resulting in high-quality hole formation.

[0033] Based on the above structure, a fixing block 96 is fixedly provided on the outer wall of the horizontal section of the L-shaped frame 91, and the fixing block 96 is slidably sleeved on the outside of the vertical rod 44.

[0034] In this embodiment, the vertical rod 44 and the fixed block 96 slidably connected to it facilitate the synchronous sliding adjustment of the rotating opening assembly 9 and the clamping assembly 4 on the same side.

[0035] The working principle of this utility model is as follows:

[0036] In use, first, place one end of the signboard against the fixed plate 2. Then, start the servo motor 11 to control the bidirectional lead screw 7 to rotate. Control the two sets of rotating hole-opening components 9 to drive the two left and right vertical rods 44 and the two moving plates 42 to slide horizontally along the limit rod 41 and move closer to each other until the two moving plates 42 are against the left and right ends of the signboard respectively. This makes the two drill rods 94 located on the left and right sides above the signboard, which is convenient for determining the positioning hole position of the same batch of signboards of the same size and specifications, ensuring the accuracy of the hole position and facilitating subsequent installation.

[0037] Place the sign to be drilled between two adjustable movable plates 42 and make it contact the fixed plate 2. Then, simultaneously open the electric telescopic rod 5 and the drive motor 10. The rotating horizontal axis 8 can drive the sleeve 92 and the first bevel tooth 93 to rotate by using the symmetrical protruding structure on its outer wall. The drill rod 94 can be controlled to rotate rapidly while moving vertically downward by using the second bevel tooth 95 that meshes with the first bevel tooth 93. This can reduce the drilling resistance and achieve fast and efficient drilling.

[0038] It should be noted that this device is powered by an external power source. The two electric telescopic rods 5 are of the same model. Moreover, the electric telescopic rods 5, drive motor 10 and servo motor 11 are electrically connected to the external controller. The specific control methods are all mature existing technologies and are not the key innovation direction of this case, so they will not be described in detail.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any equivalent changes, modifications, substitutions, and variations made by those skilled in the art based on the concept of this utility model and on the basis of existing technology through logical analysis, reasoning, or limited experiments shall be within the scope of protection defined by the claims.
