Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, and in particular to a tile positioning drill. Background Technology

[0002] During the installation of tiles on walls, it is often necessary to drill holes in appropriate locations within the tiles to allow water pipes or electrical conduits to pass through for wiring. The tiles are then then adhered to the wall. However, the smooth surface of tiles makes it easy to slip and cause the hole to shift, resulting in poor drilling quality, tile damage, and increased scrap rates.

[0003] To address this issue, existing drilling devices use suction cups to secure themselves to the tiles, preventing slippage during drilling, and employ a three-dimensional motion mechanism to control the drilling position. However, these existing devices are complex in structure, heavy, cumbersome to package and transport, inconvenient to operate, and prone to damaging the tiles. Therefore, there is an urgent need to develop a new drilling device that is lightweight, easy to package and transport, convenient to operate, and ensures that the tiles are not easily damaged during drilling. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a tile positioning and drilling tool, which has a simple structure, light weight, is easy to transport, and is easy to operate. It can avoid damage to tiles during drilling, improve the drilling effect, and reduce the defect rate of tiles.

[0005] This utility model embodiment provides a tile positioning drill, which includes: A drilling mechanism, which includes a drill bit assembly; A positioning mechanism, which is separately arranged from the drilling mechanism, includes a positioning plate, a limiting plate, a locking component, positioning wheels, a manual suction cup, and a buffer pad. The positioning plate is located below the limiting plate and together with the limiting plate forms a through hole for the drill bit assembly to extend into and extend in the vertical direction. The positioning plate is slidably connected to the limiting plate in a first direction to make the through hole larger or smaller. The locking component is located between the positioning plate and the limiting plate and is configured to lock the positioning plate and the limiting plate. Both the positioning plate and the limiting plate are provided with two positioning wheels spaced apart in a second direction. The axial direction of the positioning wheels extends in the vertical direction. All the positioning wheels are configured to roll into contact with the outer peripheral surface of the drill bit assembly located in the through hole. One end of the positioning plate is provided with a manual suction cup for vacuum adsorption of the ceramic tile, and the other end is provided with several buffer pads for contact with the ceramic tile. The punching mechanism and the positioning plate are provided with a guide rod extending in the vertical direction, and the other is provided with a spring. The spring is configured to fit on the guide rod and extend and retract along the guide rod, with the first direction, the second direction and the vertical direction being perpendicular to each other.

[0006] The tile positioning and drilling device according to the present invention has at least the following beneficial effects: When drilling a tile, firstly, the locking component releases the locking effect on the positioning plate and the limiting plate, and adjusts the relative position between the positioning plate and the limiting plate along the first direction, so that the drill bit assembly of the drilling mechanism can extend into the through hole defined by the positioning plate and the limiting plate. At the same time, the outer peripheral surfaces of all positioning wheels arranged around the through hole can roll and contact the outer peripheral surface of the drill bit assembly, thereby determining the position of the drilling mechanism relative to the positioning mechanism. Then, the locking component is used to fasten and lock the positioning plate and the limiting plate. Then, according to the drilling requirements... The drill bit assembly is positioned relative to the tile by adjusting its position. A vacuum suction cup is used to apply suction to the tile surface, fixing the positioning mechanism relative to the tile and thus determining the position of the drill bit assembly. Next, the drilling mechanism is driven to approach the tile along the axis of the through hole to drill a hole. During this process, the guide rod, spring, and positioning wheel work together to guide and buffer the drilling mechanism, ensuring stable feed motion and improving drilling quality. Simultaneously, a buffer pad prevents severe damage to the tile from collisions with the positioning plate during drilling, reducing the tile defect rate.

[0007] Moreover, since the positioning mechanism and drilling mechanism have simple structures and adopt separate and independent settings, the positioning mechanism and drilling mechanism can be separated, which facilitates packaging, transportation and handling onto the tiles. At the same time, the position determination of the tiles, positioning mechanism and drilling mechanism can be easily and conveniently completed by operating the manual suction cup and locking components and adjusting the distance between the limiting plate and the positioning plate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is for reference. Figures 1 to 4 This invention describes a tile positioning drill provided according to an embodiment of the present invention.

[0024] like Figures 1 to 4As shown, the tile positioning drill according to this embodiment of the utility model can be applied to the drilling process of tiles before installation on walls. This tile positioning drill has the advantages of simple structure, light weight, convenient packaging and transportation, and easy operation. It can effectively avoid damage to tiles during drilling, thereby improving the drilling effect and reducing the tile scrap rate.

[0025] The tile positioning drill has a first direction, a second direction, and a vertical direction, wherein the first direction, the second direction, and the vertical direction are arranged perpendicularly to each other. In this embodiment, it is assumed that the first direction is the left-right direction and the second direction is the front-back direction.

[0026] like Figures 1 to 4 As shown, the structure of the tile positioning drill includes a drilling mechanism 100, a positioning mechanism 200, a guide rod 270, and a spring 130.

[0027] The drilling mechanism 100 is used to drill holes in ceramic tiles. It includes a drill bit assembly 110 and a drive assembly, which includes a motor that drives the drill bit assembly 110 to rotate at high speed around its central axis, thus enabling it to drill holes in the ceramic tiles. The drill bit assembly 110 includes a drill rod 111 and a mounting head. The mounting head is cylindrical, and its upper part is mounted on the output shaft of the motor. The upper end of the drill rod 111 is fixedly connected to the lower part of the mounting head. Furthermore, the drilling mechanism 100 is a handheld device; specifically, it has a handle for easy operation by the worker.

[0028] The positioning mechanism 200 and the drilling mechanism 100 are separately configured. Therefore, the tile positioning and drilling device has an assembled state and a disassembled state. In the assembled state, the positioning mechanism 200 and the drilling mechanism 100 are connected to facilitate drilling the tiles. In the disassembled state, the positioning mechanism 200 and the drilling mechanism 100 are separated to facilitate packaging and transportation of the positioning mechanism 200 and the drilling mechanism 100 separately.

[0029] like Figures 1 to 4 As shown, the positioning mechanism 200 includes a positioning plate 210, a limiting plate 220, a locking component, a positioning wheel, a manual suction cup 230, and a buffer pad 250.

[0030] The positioning plate 210 is located below the limiting plate 220, and the positioning plate 210 and the limiting plate 220 together form a through hole 280. The through hole 280 extends axially in the vertical direction and can be used for the drill bit assembly 110 of the drilling mechanism 100 to extend into, so that the drill bit assembly 110 can drill a hole in the tile. The positioning plate 210 and the limiting plate 220 are slidably connected in a first direction, so that the positioning plate 210 can move linearly relative to the limiting plate 220 in the first direction to adjust the relative position of the positioning plate 210 and the limiting plate 220 in the first direction, thereby making the through hole 280 larger or smaller.

[0031] It is understood that the positioning plate 210 and the limiting plate 220 can be slidably connected through a guide rail slider pair, an optical axis guide sleeve combination, or a protrusion-groove structure. In this embodiment, the positioning plate 210 is provided with limiting portions 211 on both sides along the second direction. The limiting portions 211 are integrally formed with the positioning plate 210 and extend along the first direction. The limiting portions 211 can be cuboid in shape, and the distance between the two limiting portions 211 along the second direction is equal to the dimension of the limiting plate 220 along the second direction. The two sides of the limiting plate 220 along the second direction are respectively fitted with the two limiting portions 211, so that the limiting plate 220 can slide relative to the positioning plate 210 along the first direction under the limiting action of the two limiting portions 211.

[0032] Specifically, such as Figures 2 to 4 As shown, the positioning plate 210 has a first notch on the side of the limiting plate 220 along the first direction, and the limiting plate 220 has a second notch on the side of the positioning plate 210 along the first direction. Moreover, the first notch and the second notch are arranged opposite to each other along the first direction, so that the first notch and the second notch can jointly form a through hole 280.

[0033] Understandably, in some examples, the first and second notches form a V-shape when viewed vertically, so that they together define a square through-hole 280. In other examples, the first and second notches form a semi-circle when viewed vertically. Furthermore, it is possible that in other examples, the first and second notches form an isosceles trapezoid. When the distance between the positioning plate 210 and the limiting plate 220 in the first direction increases, the through-hole 280 becomes larger, allowing a larger diameter drill bit assembly 110 to enter; when the distance between the positioning plate 210 and the limiting plate 220 in the first direction decreases, the through-hole 280 becomes smaller, allowing only a smaller diameter drill bit assembly 110 to enter. This design allows for the replacement of different drill bit assemblies 110 according to drilling requirements to meet the drilling needs of tiles.

[0034] The specific shapes of the positioning plate 210 and the limiting plate 220 are not limited and can be set according to actual design requirements. The positioning plate 210 and the limiting plate 220 can be made of metals such as stainless steel to improve their strength and make them less prone to deformation.

[0035] The positioning plate 210 is provided with guide rods 270, which can be cylindrical or cylindrically stepped. The length of the guide rods 270 extends in the vertical direction and is fixedly connected to the positioning plate 210. The drilling mechanism 100 is provided with springs 130, one end of which is fixedly connected to the drilling mechanism 100. The springs 130 can extend or retract along the axial direction of the drill assembly 110. The number of springs 130 is the same as the number of guide rods 270, and the springs 130 are configured to fit on the guide rods 270 and extend or retract along the length of the guide rods 270.

[0036] In this embodiment, two guide rods 270 are provided, and the two guide rods 270 are arranged at a certain interval along the second direction; correspondingly, two springs 130 are provided, and the two springs 130 are arranged at a certain interval along the second direction. The drilling mechanism 100 is provided with a fixing plate 120, and the upper end of the spring 130 can be fixedly connected to the fixing plate 120 by welding or other means.

[0037] Understandably, when assembling the drilling mechanism 100 and the positioning mechanism 200, the spring 130 can be fitted onto the guide rod 270, allowing the drilling mechanism 100 to move relative to the positioning mechanism 200 along the length direction (i.e., the vertical direction) of the guide rod 270. Furthermore, the spring 130 provides good cushioning for the drilling mechanism 100, preventing excessively fast feed speeds that could affect the drilling effect. Additionally, the drilling mechanism 100 may also have a guide hole. Specifically, the guide hole is located on the fixed plate 120, extending through the thickness of the fixed plate 120. The guide rod 270 can be inserted into the guide hole and fitted to its inner circumferential surface. Alternatively, the guide rod 270 can be mounted on the drilling mechanism 100, and the spring 130 can be mounted on the positioning plate 210.

[0038] A locking component is disposed between the positioning plate 210 and the limiting plate 220, and is configured to lock the positioning plate 210 and the limiting plate 220 to ensure that the positioning plate 210 and the limiting plate 220 are fixed together and do not move relative to each other. After the locking component is released, the positioning plate 210 and the limiting plate 220 can slide relative to each other along a first direction.

[0039] Specifically, such as Figures 1 to 4As shown, the locking assembly includes a locking screw 240. The positioning plate 210 has two screw holes arranged at certain intervals along a second direction, with the axial direction of the screw holes extending vertically. The screw holes can be blind holes or through holes. The limiting plate 220 has two elongated holes 221 arranged at certain intervals along a second direction, extending vertically and through each other. The length of the elongated holes 221 extends along a first direction. When the limiting plate 220 and the positioning plate 210 are stacked vertically, the elongated holes 221 and the screw holes are positioned opposite each other and are interconnected. The locking screw 240 is configured to pass through the elongated holes 221 and connect with the screw holes to tightly lock the positioning plate 210 and the limiting plate 220 together.

[0040] Furthermore, the upper part of the locking screw 240 is provided with a Phillips-shaped handle, which can be manually rotated by the operator to tighten or loosen the locking screw 240. Of course, it is not excluded that in other embodiments, a wrench can be used to apply a rotational force to the head of the locking screw 240.

[0041] The positioning plate 210 is provided with two positioning wheels, which are arranged at certain intervals along the second direction; similarly, the limiting plate 220 is also provided with two positioning wheels, which are arranged at certain intervals along the second direction. Moreover, the axial direction of each positioning wheel extends in the vertical direction. The positioning wheel portion is located within the through hole 280, and all positioning wheels are configured to roll into contact with the outer peripheral surface of the drill assembly 110 located in the through hole 280. At this time, all positioning wheels are arranged circumferentially around the drill assembly 110, and all positioning wheels can perform a positioning function on the drill assembly 110 to determine the position of the drill assembly 110 on the positioning mechanism 200. At the same time, the drill assembly 110 can only move relative to the positioning mechanism 200 in the vertical direction.

[0042] Specifically, the positioning wheel located on the positioning plate 210 is designated as the first positioning wheel 261. The first positioning wheel 261 can be mounted on the positioning plate 210 via a connecting shaft or mounting bolts, thereby achieving a rotatable connection between the first positioning wheel 261 and the positioning plate 210, allowing the first positioning wheel 261 to rotate around its own central axis. The guide rod 270 is located above the first positioning wheel 261, and the first positioning wheel 261 is configured to rotate relative to the guide rod 270.

[0043] In this embodiment, the first positioning wheel 261 is provided with a first threaded fastener and a first nut, and the positioning plate 210 is provided with a first connecting hole. The first connecting hole extends axially in the vertical direction. The first threaded fastener passes through the first connecting hole and the mounting hole of the first positioning wheel 261 and is threadedly connected to the first nut. The first nut is cylindrical and stepped. The upper part of the first nut is provided as a guide rod 270. Therefore, the spring 130 can be sleeved on the upper part of the first nut and abut against the first nut.

[0044] Specifically, the positioning wheel located on the limiting plate 220 is designated as the second positioning wheel 262. The second positioning wheel 262 can be installed on the limiting plate 220 through a connecting shaft or mounting bolts, so that the second positioning wheel 262 and the limiting plate 220 are rotatably connected, allowing the second positioning wheel 262 to rotate around its own central axis.

[0045] In this embodiment, the second positioning wheel 262 is provided with a second threaded fastener and a second nut, and the limiting plate 220 is provided with a second connecting hole. The second connecting hole extends axially in the vertical direction. The second threaded fastener passes through the second connecting hole and the mounting hole of the second positioning wheel 262 and is threadedly connected to the second nut.

[0046] It is understandable that both the first and second threaded fasteners are bolts. The first positioning wheel 261 can be mounted on the first threaded fastener via a bushing or bearing, and similarly, the second positioning wheel 262 can be mounted on the second threaded fastener via a bushing or bearing.

[0047] One end of the positioning plate 210 is equipped with a manual suction cup 230, and the other end of the positioning plate 210 is equipped with several buffer pads 250, which are fixedly connected to the positioning plate 210. The function of the manual suction cup 230 is to vacuum-adhere the tile, and the function of the buffer pads 250 is to abut against the tile.

[0048] In this embodiment, two buffer pads 250 are provided, and the two buffer pads 250 are arranged at intervals along the second direction. The manual suction cup 230 and the buffer pads 250 are respectively provided on both sides of the positioning plate 210 along the first direction.

[0049] Understandably, by operating the handle 231 of the manual suction cup 230, the operator can cause the manual suction cup 230 to apply vacuum adsorption to the tile or release the vacuum adsorption effect. When the manual suction cup 230 is vacuum adsorbing the surface of the tile, the lower surface of the buffer pad 250 abuts against the surface of the tile.

[0050] In the use of the tile positioning driller provided in this embodiment of the present invention, when it is necessary to drill a hole in a tile, the locking component first releases the locking effect on the positioning plate 210 and the limiting plate 220, and adjusts the relative position between the positioning plate 210 and the limiting plate 220 along the first direction, so that the drill bit assembly 110 of the drilling mechanism 100 can extend into the through hole 280 defined by the positioning plate 210 and the limiting plate 220. At the same time, the outer peripheral surfaces of all the positioning wheels arranged around the through hole 280 can roll and contact the outer peripheral surface of the drill bit assembly 110, thereby determining the position of the drilling mechanism 100 relative to the positioning mechanism 200. Then, the locking component is used to fasten and lock the positioning plate 210 and the limiting plate 220.

[0051] Then, the position of the drill bit assembly 110 relative to the tile is adjusted according to the drilling requirements, and the surface of the tile is vacuum-adsorbed by the manual suction cup 230 to fix the positioning mechanism 200 relative to the tile, thereby determining the position of the drill bit assembly 110 relative to the tile. Next, the operator drives the drilling mechanism 100 to move along the axis of the through hole 280 to overcome the elastic force of the spring 130, so that the drill bit assembly 110 smoothly approaches the tile to drill a hole in the tile. During this process, the guide rod 270, the spring 130 and the positioning wheel cooperate with each other to guide and buffer the drilling mechanism 100, so that the drilling mechanism 100 can make stable feed movements, avoid the drilling mechanism 100 from tilting during the drilling process, and reduce the force of the drilling mechanism 100 on the positioning wheel, thereby helping to improve the drilling quality. At the same time, the buffer pad 250 is used to prevent the tile from being seriously damaged due to collision with the positioning plate 210 during the drilling process, thus reducing the tile defect rate.

[0052] Furthermore, since the positioning mechanism 200 and the drilling mechanism 100 have simple structures and are set up separately and independently, the positioning mechanism 200 and the drilling mechanism 100 can be separated for easy packaging, transportation and handling onto the tiles. At the same time, the staff only needs to operate the manual suction cup 230 and the locking component, and adjust the distance between the limiting plate 220 and the positioning plate 210 to easily and conveniently complete the position determination of the tiles, the positioning mechanism 200 and the drilling mechanism 100.
