Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of punching positioners, and in particular to a rotary punching positioner and a method of using the same. Background Art
[0002] In the fields of mechanical processing, construction installation, and handicraft production, drilling positioning is a key step to ensure hole accuracy and operational efficiency. Traditional drilling positioning tools usually adopt a single-function design, such as manually marking the hole position after fixing the workpiece with a simple clamp, or relying on external auxiliary tools (such as rulers and templates) for positioning. This type of method has obvious defects: on the one hand, manual marking is susceptible to human error, resulting in hole position deviation; on the other hand, the fixing device is separated from the positioning mechanism, requiring multiple adjustments and insufficient stability. Especially when working on smooth or inclined surfaces, drilling failures are prone to tool displacement. In addition, the existing tools lack visual auxiliary functions in low-light environments, further increasing the difficulty of operation.
[0003] A Chinese patent discloses a punch locator with the publication number: (CN 104369223 A). The punch locator comprises a sleeve with a through hole at the center of the sleeve ground surface, a spring provided outside the through hole, a steel chisel inserted into the spring, a protrusion provided on the steel chisel portion, the lower end surface of the protrusion pressing against the upper end of the spring, the sleeve being divided into an upper sleeve and a lower sleeve, the upper and lower sleeves being screwed together, a skirt being provided on the lower outer portion of the lower sleeve, the skirt being umbrella-shaped and having a cavity therein, but this punch locator has scattered and single functions, poor stability and insufficient environmental adaptability, making it difficult to meet the requirements of efficient and accurate positioning. Therefore, a rotary punch locator and a method for using the same are needed. Summary of the Invention
[0004] The purpose of the present invention is to solve the problems of traditional punch locators, which have scattered and single functions, poor stability and insufficient environmental adaptability, and are difficult to meet the needs of efficient and accurate positioning, and to propose a rotary punch locator and its use method.
[0005] The technical solution adopted by the present invention to solve its technical problems is: a rotary punching positioner, including a variable aperture mechanism and a knob suction cup mechanism, characterized in that: the variable aperture mechanism and the knob suction cup mechanism cooperate with each other, the overall spacing between the variable aperture mechanism and the knob suction cup mechanism is 225.12mm, the variable aperture mechanism includes a base, a blade adjustment dial is installed on the top of the base, an aperture end cover is installed on the top of the dial, a variable blade is provided in the center of the aperture end cover, a suction cup transmission assembly is provided inside the knob suction cup mechanism, and an annular anti-slip coating is provided on the bottom of the base. Through the coordinated design of the variable aperture and the knob suction cup, the functional integration of positioning and fixing is achieved, simplifying the operation process; the anti-slip coating on the base enhances the contact stability with the knob suction cup, prevents displacement during the punching process, and improves positioning reliability.
[0006] Preferably, the variable blades are arranged radially from the center of the aperture end cap. The number of variable blades ranges from 6 to 12, and the angles between adjacent blades are equal. This radial arrangement of variable blades allows for uniform opening and closing, ensuring a regular shape for the stop hole and preventing deviation in the perforation position. The number of blades and the angle design ensure smooth opening and closing, enhancing smooth adjustment of the stop hole size.
[0007] Preferably, a scale is provided on one side of the outer wall of the aperture end cap. The scale is arranged circumferentially along the aperture end cap, with a numerical range of 5 to 68 mm and a minimum graduation of 1 mm. The scale provides an intuitive dimensional reference, helping the user quickly adjust the limit hole to the target size and improving positioning accuracy. The circumferential scale facilitates real-time observation of the value during rotational adjustment, reducing the number of repeated adjustments.
[0008] Preferably, a slide is provided between the aperture end cap and base, and the turntable. A clamping slider is connected to one end of the turntable, which cooperates with the slide. The axial distance between the slider and the center of the variable blade is 79.25mm. The cooperation between the slide and the clamping slider stabilizes the blade angle, preventing the blade from loosening after adjustment and ensuring the consistency of the limit hole size. The positioning design of the clamping slider optimizes the operating space, allowing users to directly apply force to fix the blade, improving adjustment efficiency.
[0009] Preferably, the suction cup transmission assembly includes a fixed suction cup, a suction cup turntable mounted on top of the fixed suction cup, a suction cup end cap mounted on top of the suction cup turntable, and a stud at the center of the top of the fixed suction cup, mounted on a tightening nut. The stud and tightening nut cooperate to convert rotational motion into up and down movement of the suction cup, achieving precise control of vacuum adsorption. The split structure of the fixed suction cup, turntable, and end cap facilitates assembly and maintenance, reducing the risk of failure.
[0010] Preferably, the outer wall of the stud is provided with a guide groove, which is equipped with multiple guide steel balls, and the tightening nut is provided with a synchronous stop groove associated with the tightening nut. The guide steel balls reduce friction between the stud and the guide groove, making the suction cup rise and fall more smoothly and improving the response speed of suction and fixation. The synchronous stop groove and the steel balls cooperate to precisely lock the suction cup in place, preventing loosening after suction and enhancing fixation stability.
[0011] Preferably, a groove is provided on one side of the outer wall of the stud, within which a spring is positioned. A retaining steel ball is positioned on one side of the spring, and the retaining steel ball is associated with the synchronous retaining groove. The spring and retaining steel ball form an automatic reset mechanism, ensuring that the steel ball automatically snaps into the retaining groove when the suction cup is properly attached, simplifying operation. The cooperation between the retaining steel ball and the synchronous retaining groove provides clear locking feedback, helping the user determine the suction status.
[0012] Preferably, the outer wall of the suction cup turntable is provided with annular corrugated lines, which are evenly distributed along the circumference of the suction cup turntable. The annular corrugated lines increase the friction of the outer wall of the turntable, making it easier for the user to apply force during rotation and improving the operating feel. The evenly distributed design avoids local stress concentration and prolongs the service life of the turntable.
[0013] Preferably, the top outer wall of the suction cup end cap is provided with an annular groove along the circumference, and a fluorescent ring is provided within the annular groove. The fluorescent ring glows in low-light environments, helping the user quickly locate the center of the suction cup and improving operating efficiency in low-light environments. The annular groove protects the fluorescent ring from external damage, extending its service life.
[0014] Preferred: (1) Step 1: Pre-fix the knob suction cup mechanism Lightly press the bottom of the fixed suction cup onto the smooth surface of the target workpiece, slowly rotate the suction cup turntable, and initially fix it using the vacuum adsorption principle; rotate the suction cup turntable clockwise, and the stud pushes the fixed suction cup downward. When the limit steel ball is stuck in the synchronous limit groove, accompanied by a slight resistance, the suction cup forms a stable vacuum adsorption area; (2) Step 2: Adjusting the position of the variable aperture mechanism Place the variable aperture mechanism directly above the knob suction cup mechanism, with the annular non-slip coating on the bottom of the base in contact with the top of the suction cup to prevent slipping. Gently turn the clamping slider to drive the blade adjustment dial, causing the variable blades to radially expand or close. Initially adjust the limit hole size to close to the target value. Once the size is adjusted to the appropriate value, push the clamping slider to secure it and lock the blade angle. Use the fluorescent ring's luminous effect within the annular groove to quickly locate the center and enhance visibility. (3) Step 3: Disassembly and Reset Rotate the suction cup turntable counterclockwise to disengage the limiting steel ball from the synchronous limiting groove, and the fixed suction cup releases the vacuum adsorption state.
[0015] The present invention is beneficial in that: This application provides an integrated, highly stable rotary punch locator, which achieves seamless connection between positioning and fixation through the collaborative design of the variable aperture mechanism and the knob suction cup mechanism. The variable aperture mechanism uses radially arranged variable blades, combined with a scale and a clamping slider, which can quickly adjust and lock the limit hole size, effectively avoiding the hole position deviation caused by manual marking of traditional tools, and significantly improving positioning accuracy and operating efficiency; the knob suction cup mechanism converts the rotational motion into a precise suction cup lifting action through the linkage design of the stud, guide groove and synchronous limit groove, forming a stable vacuum adsorption area, solving the problem of easy displacement of traditional fixtures on smooth surfaces. At the same time, the annular corrugated lines and fluorescent rings enhance the feel of the rotation operation and visibility in low-light environments, further reducing the difficulty of operation. In addition, the anti-slip coating of the base and the annular groove structure optimize the coordination stability between the two mechanisms, and the step-by-step operation process design reduces the user's learning cost, so that the tool can still maintain efficient and reliable performance under complex working conditions.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0024] See also Figure 1-5 As shown: A rotary hole punching positioner includes a variable aperture mechanism 1 and a knob suction cup mechanism 5, characterized in that the variable aperture mechanism 1 and the knob suction cup mechanism 5 cooperate with each other, the overall spacing between the variable aperture mechanism 1 and the knob suction cup mechanism 5 is 225.12 mm, the variable aperture mechanism 1 includes a base 8, a blade adjustment dial 9 is mounted on the top of the base 8, an aperture end cover 10 is mounted on the top of the dial, and a variable blade 2 is provided at the center of the aperture end cover 10, a suction cup transmission assembly is provided within the knob suction cup mechanism 5, and an annular non-slip coating 20 is provided on the bottom of the base 8. The coordinated design of the variable aperture and the knob suction cup achieves the integration of positioning and fixing functions, simplifying the operating process; the non-slip coating on the base 8 enhances the contact stability with the knob suction cup, preventing displacement during the punching process and improving positioning reliability.
[0025] In this embodiment, the variable blades 2 are radially arranged with the center of the aperture end cap 10 as the base point. The number of variable blades 2 ranges from 6 to 12, and the angles between adjacent blades are equal. This radial arrangement of variable blades 2 allows for uniform opening and closing, ensuring a regular shape for the stop hole and preventing deviation in the perforation position. The number of blades and the angle design ensure smooth opening and closing, enhancing smooth adjustment of the stop hole size.
[0026] In this embodiment, a scale 3 is provided on one side of the outer wall surface of the aperture end cap 10. The scale 3 is arranged circumferentially along the aperture end cap 10 and has a numerical range of 5 to 68 mm. The minimum graduation value of the scale 3 is 1 mm. The scale 3 provides an intuitive dimensional reference, helping the user to quickly adjust the limit hole to the target size and improve positioning accuracy. The circumferential scale 3 facilitates real-time observation of the value during rotational adjustment, reducing the number of repeated adjustments.
[0027] In this embodiment, a slideway is provided between the aperture end cap 10 and the base 8, and the turntable. A clamping slider 4 is connected to one end of the turntable, mating with the slideway. The axial distance between the slider 4 and the center of the variable blade 2 is 79.25 mm. The combination of the slideway and the clamping slider 4 stabilizes the blade angle, preventing loosening after adjustment and ensuring consistent size of the retaining holes. The positioning design of the clamping slider 4 optimizes operating space, facilitating direct application of force to secure the blade, and improving adjustment efficiency.
[0028] In this embodiment, the suction cup transmission assembly includes a fixed suction cup 11, with a suction cup turntable mounted on top of the fixed suction cup 11, and a suction cup end cap 13 mounted on top of the turntable. A stud 12 is located at the center of the top of the fixed suction cup 11, and a tightening nut 15 is mounted on the stud 12. The stud 12 and tightening nut 15 cooperate to convert rotational motion into vertical movement of the suction cup, achieving precise control of vacuum suction. The split structure of the fixed suction cup 11, turntable, and end cap facilitates assembly and maintenance, reducing the risk of failure.
[0029] In this embodiment, the outer wall of the stud 12 is provided with a guide groove 17, which is equipped with multiple guide steel balls 16. The tightening nut 15 is provided with a synchronous stop groove 14 associated with the tightening nut 15. The guide steel balls 16 reduce friction between the stud 12 and the guide groove 17, allowing the suction cup to rise and fall more smoothly and improving the response speed of suction and fixation. The synchronous stop groove 14 cooperates with the steel balls to accurately lock the suction cup position, preventing loosening after suction and enhancing fixation stability.
[0030] In this embodiment, a groove is formed on one side of the outer wall of the stud 12, within which a spring 19 is disposed. A retaining steel ball 18 is disposed on one side of the spring 19, and the retaining steel ball 18 is associated with the synchronous retaining groove 14. The spring 19 and retaining steel ball 18 form an automatic reset mechanism, ensuring that the steel ball automatically snaps into the retaining groove when the suction cup is properly attached, simplifying operation. The cooperation between the retaining steel ball 18 and the synchronous retaining groove 14 provides clear locking feedback, helping the user determine the suction status.
[0031] In this embodiment, the outer wall of the suction cup turntable is provided with annular corrugated lines 7, which are evenly distributed along the circumference of the suction cup turntable. The annular corrugated lines 7 increase the friction of the turntable's outer wall, making it easier for the user to apply force during rotation and improving the operating feel. The evenly distributed design avoids localized stress concentration and prolongs the turntable's service life.
[0032] In this embodiment, the top outer wall of the suction cup end cap 13 is provided with an annular groove along its circumference, within which a fluorescent ring 6 is positioned. The fluorescent ring 6 illuminates in low-light environments, helping the user quickly locate the center of the suction cup and improving operational efficiency in dimly lit environments. The annular groove protects the fluorescent ring 6 from external damage, extending its service life.
[0033] In this embodiment: Step 1: Pre-fix the knob suction cup mechanism 5 Gently place the bottom of the fixed suction cup 11 on the smooth and flat surface of the target workpiece, ensuring that the contact surface is free of dust and bumps to ensure optimal airtightness; accurately align the center of the suction cup with the area to be punched on the workpiece, and slowly rotate the suction cup turntable clockwise; the stud 12 gradually presses down the fixed suction cup 11 as the turntable rotates, making it fit tightly against the workpiece surface; when the limiting steel ball 18 is stuck in the synchronous limiting groove 14, a slight resistance will be felt, and the suction cup has formed a stable vacuum adsorption area; Step 2: Positioning and adjusting the variable aperture mechanism 1 Place the variable aperture mechanism 1 vertically above the knob suction cup mechanism 5, ensuring that the annular anti-slip coating 20 at the bottom of the base 8 is in close contact with the top of the suction cup to prevent slipping during the adjustment process; lightly turn the blade adjustment dial 9 to drive the variable blades 2 to expand or close radially, and preliminarily adjust the size of the limit hole to close to the target value; push the clamping slider 4 to slide along the slide groove until it is stuck in the groove at the end of the dial to lock the blade angle; with the help of the luminous effect of the fluorescent ring 6 in the annular groove, the punching center can be quickly located in a low-light environment; through the clear visibility of the fluorescent ring 6, ensure that the drill bit or punching tool is accurately aligned with the center of the limit hole, thereby improving operational accuracy.
[0034] Step 3: Punch execution Insert the punching tool (such as a drill bit) vertically into the opening area of the variable blade 2 in the center of the aperture end cover 10; fix the locator with both hands and keep it perpendicular to the workpiece to avoid tilting and causing the punching to shift; start the punching equipment and maintain uniform pressure to avoid sudden force that may cause the locator to shift; during the punching process, continue to observe whether the aperture end cover 10 remains stable to ensure that the limit hole and the drill bit are always aligned; after the drilling is completed, slowly rotate the suction cup turntable counterclockwise to disengage the limit steel ball 18 from the synchronous limit groove 14; fix the suction cup 11 to release the vacuum adsorption state, and the suction cup can be easily lifted at this time.
