Description

Technical Field

[0001] This utility model relates to the field of drilling auxiliary device technology, and in particular to an adjustable drilling positioner. Background Technology

[0002] Precise drilling is a basic requirement in machining, woodworking, and metalworking operations, but traditional positioning methods have many inconveniences: when using fixed-size templates, it is necessary to frequently change to different specifications, which is cumbersome and inefficient; manual marking and positioning is prone to errors, causing drilling deviation and affecting processing quality; ordinary clamps or suction cups are prone to loosening during operation, which cannot guarantee drilling accuracy; moreover, the limitations of a single template make it difficult to adapt to drilling needs of different sizes, which seriously restricts work efficiency and processing accuracy.

[0003] Chinese patent discloses a punching positioner (publication number: CN 210389470 U) which includes a horizontal bar, a first slider, a first connecting block, a second connecting block, a second slider, and a vertical plate. The left end of the horizontal bar is connected to the first connecting block, the upper middle of the vertical plate is connected to the second connecting block, the vertical plate is located at the lower left end of the horizontal bar, the first slider is connected to the horizontal bar, the upper left end of the first slider is provided with a first infrared emitter, and the bottom of the first slider is connected to a hydraulic cylinder. However, this punching positioner has disadvantages such as cumbersome adjustment, inaccurate positioning, unstable fixation, and limited applicability. Therefore, an adjustable punching positioner is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing hole positioners, such as cumbersome adjustment, inaccurate positioning, unstable fixation and limited application range, and to propose an adjustable hole positioner.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: An adjustable drilling positioner, comprising a turntable, characterized in that: a lower body is provided at the bottom of the turntable and is rotatably nested with the lower body; an upper body is provided at the top of the turntable and is associated with the lower body; a variable aperture mechanism is provided inside the upper body, the lower body, and the turntable; the variable aperture mechanism is composed of a ring array of variable blades, each variable blade being 8-12 arc-shaped metal pieces; the adjustable spacing of the variable aperture mechanism is 4-68mm; a suction cup is provided on one side of the upper body and is integrally formed with the suction cup; a wrench is movably connected to the center of the top of the suction cup. Precise adjustment of drilling position: Through the variable aperture mechanism, the user can flexibly adjust the hole diameter, suitable for drilling needs of different sizes, improving positioning accuracy; Stable adsorption and fixation: The suction cup design allows the positioner to be firmly adsorbed onto the workpiece surface, avoiding displacement during drilling and ensuring accurate drilling position; Convenient operation: The wrench structure facilitates quick adsorption and disassembly, improving work efficiency.

[0006] Preferably, an adjusting block extends from one end of the outer wall of the turntable, and a clamping slider is provided on the adjusting block. The clamping slider has a ring structure. The clamping slider can further lock the turntable to prevent the positioner from loosening due to vibration or external force during drilling, thus ensuring drilling accuracy. The ring structure provides uniform clamping force and is suitable for smooth or slightly uneven workpiece surfaces.

[0007] Preferably, the upper body has an auxiliary centering device on one side of its top, and an observation hole is provided on the auxiliary centering device side. The observation hole is concentrically and coaxially arranged with the upper body, lower body, and turntable. The auxiliary centering structure helps the user quickly find the drilling center, reducing adjustment time; the observation hole provides a visual reference to ensure that the drill bit is aligned with the target position, improving drilling accuracy.

[0008] Preferably, the top surface of the upper body is provided with logarithmic scale lines. Logarithmic scale lines conform to the human eye's perception of proportional changes, making aperture adjustment more intuitive and precise; users do not need to repeatedly try and adjust, and can directly and quickly set the required aperture according to the scale, reducing errors.

[0009] Preferably, the connection between the upper body and the suction cup is provided with reinforcing ribs. These ribs prevent deformation or breakage at the suction cup connection due to stress, extending the service life of the positioner. With structural reinforcement, the positioner is less prone to shaking during drilling, ensuring drilling accuracy.

[0010] Preferably, the end of the wrench is provided with anti-slip texture, which consists of equally spaced diamond-shaped protrusions with a protrusion height of 0.5~1.2mm. The diamond-shaped anti-slip texture increases friction, making the wrench operation more stable and preventing slippage that could affect the adsorption effect; it also conforms to ergonomic design, maintaining a comfortable grip even during prolonged use.

[0011] The advantages of this utility model are:

[0012] This application utilizes a variable aperture mechanism to achieve continuous adjustment from 4-68mm, adapting to different drill bit sizes without the need to change templates; auxiliary centering and observation holes ensure precise drill bit alignment, reducing human error; a suction cup and clamping slider provide double fixation, ensuring the positioner remains secure during drilling and improving processing quality; a reinforcing rib structure enhances the suction cup connection strength, preventing deformation under stress; logarithmic scale lines make hole diameter adjustment more intuitive, reducing repeated trial adjustments; a wrench controls the suction cup for one-button adsorption / release, making operation simple and quick; an anti-slip design ensures comfortable operation and reduces fatigue during prolonged use; a nested design of metal blades and a high-precision turntable ensures consistent adjustment accuracy over long-term use; and a ring-shaped clamping slider enhances stability and adapts to different workpiece surfaces.

[0019] 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 scope of protection of the present utility model. Example

[0020] Please see Figure 1-4As shown, an adjustable drilling locator includes a turntable 8. The turntable 8 has a lower body 10 at its bottom, which is rotatably nested with the lower body 10. An upper body 9 is located at the top of the turntable 8 and is associated with the lower body 10. The upper body 9, lower body 10, and turntable 8 all share a variable aperture mechanism. This mechanism consists of a ring array of variable blades 1, each blade being 8-12 arc-shaped metal pieces. The adjustable spacing of the variable aperture mechanism is 4-68mm. A suction cup 7 is integrally formed on one side of the upper body 9, and a wrench 11 is movably connected to the center of the top of the suction cup 7. The adjustable aperture mechanism allows for precise adjustment of the drilling position, enabling users to flexibly adjust the hole diameter to accommodate different drilling needs and improve positioning accuracy. The suction cup 7 design ensures the locator is firmly attached to the workpiece surface, preventing displacement during drilling and ensuring accurate drilling position. The wrench 11 facilitates quick attachment and removal, improving work efficiency.

[0021] In this embodiment, an adjusting block 3 extends from one end of the outer wall of the turntable 8, and a pressing slider 4 is provided on the adjusting block 3. The pressing slider 4 has a ring structure. The pressing slider 4 can further lock the turntable 8 to prevent the positioner from loosening due to vibration or external force during the drilling process, thus ensuring drilling accuracy. The ring structure provides uniform pressing force and is suitable for smooth or slightly uneven workpiece surfaces.

[0022] In this embodiment, an auxiliary centering device 2 is provided on one side of the top of the upper body 9, and an observation hole 12 is provided on one side of the auxiliary centering device 2. The observation hole 12 is concentrically and coaxially arranged with the upper body 9, the lower body 10, and the turntable 8. The auxiliary centering device 2 structure helps the user quickly find the drilling center and reduces adjustment time; the observation hole 12 provides a visual reference to ensure that the drill bit is aligned with the target position and improves drilling accuracy.

[0023] In this embodiment, the top surface of the upper body 9 is provided with logarithmic scale lines 5. The logarithmic scale lines 5 conform to the human eye's perception of proportional changes, making aperture adjustment more intuitive and precise; users do not need to repeatedly try and adjust, and can directly and quickly set the required aperture according to the scale, reducing errors.

[0024] In this embodiment, a reinforcing rib 6 is provided at the connection between the upper body 9 and the suction cup 7. The reinforcing rib 6 prevents the connection between the suction cup 7 and the suction cup 7 from deforming or breaking due to force, thus extending the service life of the positioner; after structural reinforcement, the positioner is less likely to shake during drilling, ensuring drilling accuracy.

[0025] In this embodiment, the end of the wrench 11 is provided with anti-slip texture 13, which consists of equally spaced diamond-shaped protrusions with a protrusion height of 0.5~1.2mm. The diamond-shaped anti-slip texture 13 increases friction, making the wrench 11 more stable to operate and preventing slippage that could affect the adsorption effect; it also conforms to ergonomic design, maintaining a comfortable grip even during prolonged operation.

[0026] The implementation principle of this embodiment is as follows:

[0027] Step 1: Installation, Fixing, and Orifice Adjustment

[0028] Place the locator on the smooth workpiece surface that needs to be drilled, press the suction cup 7 firmly against the surface, and then pull down the lever 11 on the top of the suction cup 7 to make the suction cup 7 firmly stick. The reinforcing rib 6 at the connection of the suction cup 7 ensures that it will not be damaged even if too much force is applied. Then use the adjustment lever 3 extended from the turntable 8 to rotate the adjustment lever 3 so that the internal metal blades open and close like the aperture of a camera. At the same time, observe the size scale above the aperture and adjust the hole diameter to the required size within the range of 4-68mm. Finally, push the clamping slider 4 to fix the position and prevent it from shifting during drilling.

[0029] Step 2: Precise Positioning and Drilling Preparation

[0030] Confirm the drilling position through the observation hole 12 of the top auxiliary centering device 2, ensuring that the target point is exactly in the center of the observation hole 12. After positioning, remove the auxiliary centering device 2 and select a drill bit that matches the hole diameter to prepare for drilling.

[0031] Step 3: Perform drilling and finishing work

[0032] Keep the matching electric drill pressed vertically downwards and perform drilling operations through the pre-adjusted aperture. The anti-slip design of the wrench 11 ensures a stable and reliable operation. After drilling is completed, pull the suction cup 7 and wrench 11 upwards to release the suction and easily remove the locator.
