[0039] As mentioned in the background art, in the prior art, when installers punch holes in the cabinet board to be punched, it depends entirely on personal feeling and experience. In most cases, to achieve precise punching, multiple attempts are often required to complete the punching, which not only has low installation efficiency but also low installation accuracy.

[0040] To solve the above problems, the present application provides a punching positioning device. By setting a plurality of scale lines and a movable hole position positioning member, the fixed identification hole can be accurately corresponded to the preset scale line, thereby ensuring the accuracy of the punching position, reducing errors, and when punching holes on the same type of cabinet board each time, the same settings and operation procedures can be followed to ensure the consistency of the punching position each time, improving the quality stability of the product. In addition, the staff does not need to perform cumbersome measurements and markings, and can directly adjust according to the scale line and positioning identification, saving the time for positioning the hole position, improving the installation efficiency and installation accuracy, thus accelerating the process of the entire punching operation, and the accurate punching position helps the smooth splicing and installation of the cabinet board during assembly, avoiding multiple drilling on the cabinet board to be punched, and improving the installation efficiency and installation accuracy.

[0041] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0042] See Figure 1 and Figure 2 , this embodiment provides a punching positioning device 1. The punching positioning device 1 is used to position the hole position when punching holes in the cabinet board 20 of the cabinet 2. The punching positioning device 1 includes: a reference positioning member 100 and a hole position positioning member 200. The reference positioning member 100 is provided with a plurality of scale lines 101 along a first direction, and the reference positioning member 100 is used to be arranged on the cabinet board 20 to be punched; the hole position positioning member 200 is movably arranged on the reference positioning member 100 along the first direction, and a positioning identification 201 is arranged on the hole position positioning member 200. The positioning identification 201 can correspond to the preset scale line when the hole position positioning member 200 moves relative to the reference positioning member 100 along the first direction, so that the positioning identification 201 is located at the hole position to be punched on the cabinet board 20.

[0043] Wherein, the above-mentioned first direction is Figure 1 the direction indicated by the arrow X in

[0044] It should be noted that the above-mentioned multiple scale lines 101 respectively correspond to multiple sizes (height or length). The preset scale lines should be understood as the scale markings set in advance in the punching positioning device 1 according to design requirements, standard specifications or specific process requirements, and are used to indicate the accurate punching positions. When the positioning mark 201 on the hole position positioning member 200 corresponds to the preset scale line, the accurate position to be punched on the cabinet board 20 can be determined. The position to be punched should be understood as the specific position that is pre-specified but not yet punched on the cabinet board 20 according to design plans or actual assembly needs.

[0045] It is worth noting that the measuring ranges corresponding to the multiple scale lines can be set according to actual needs. For example, the measuring ranges can be 0mm - 50mm, 0mm - 60mm, 0mm - 80mm, 0mm - 100mm, 0mm - 120mm, etc., and are not limited here.

[0046] Therefore, when punching is required on the cabinet board 20 to be punched, first find a reference point on the cabinet board 20 to be punched, and determine the distance between the position to be punched and this reference point on the cabinet board 20 to be punched according to actual needs. Determine the scale line 101 corresponding to the preset scale line according to this distance, and then move the hole position positioning member 200 relative to the reference positioning member 100 in the first direction until the positioning mark 201 on the hole position positioning member 200 corresponds to the preset scale line. Then place the punching positioning device 1 on the reference point of the cabinet board 20 to be punched. At this time, the positioning mark 201 is located at the position to be punched on the cabinet board 20, and the staff only needs to punch at the position to be punched indicated by the positioning mark 201. Or, place the punching positioning device 1 on the reference point of the cabinet board 20 to be punched, and then move the hole position positioning member 200 relative to the reference positioning member 100 in the first direction until the positioning mark 201 on the hole position positioning member 200 corresponds to the preset scale line. At this time, the positioning mark 201 is located at the position to be punched on the cabinet board 20, and the staff only needs to punch at the position to be punched indicated by the positioning mark 201.

[0047] Compared with punching on the cabinet board 20 based on personal feeling and experience in the related art, in this embodiment, by providing a punching positioning device 1, it is possible to accurately correspond the fixed identification holes with the preset scale lines by setting a plurality of scale lines 101 and movable hole position positioning members 200, thereby ensuring the accuracy of the punching position, reducing errors, and when punching on the same type of cabinet board 20 each time, the same settings and operation procedures can be followed to ensure the consistency of the punching position each time, improving the quality stability of the product. In addition, the staff does not need to perform cumbersome measurements and markings, and can directly adjust according to the scale lines 101 and positioning marks 201, saving the time for positioning the hole positions, thus accelerating the process of the entire punching operation, and the accurate punching position helps the smooth splicing and installation of the cabinet board 20 during assembly, avoiding multiple drilling on the cabinet board 20 to be punched, and improving the installation efficiency and installation accuracy.

[0048] Exemplarily, when punching is required on the cabinet board 20 to be punched, first measure the distance from the hinge hole 22 on the door panel 21 of the cabinet 2 to the upper and lower ends with a ruler (i.e., Figure 2 the distance indicated by h in the figure) and then add the gap between the door panel 21 of the cabinet 2 and the upper and lower parts of the cabinet 2 (i.e., Figure 2 the distance indicated by d in the figure) to obtain a final data, for example: 50 mm. At this time, adjust the position of the hole position positioning member 200 in the first direction according to this dimension, so that the positioning mark 201 aligns with the position of the 50 mm scale line 101. Then, bring the punching positioning device 1 into the cabinet 2 and align the 0 scale line 101 with the surface of the top plate of the cabinet 2 facing the internal space of the cabinet 2, or, align the 0 scale line 101 with the surface of the bottom plate of the cabinet 2 facing the internal space of the cabinet 2 and make the reference positioning member 100 closely adhere to the vertical outer side plate of the cabinet 2. In this way, the positioning mark 201 is located at the position to be punched on the cabinet board 20, and the staff only needs to punch at the position to be punched indicated by the positioning mark 201.

[0049] In a possible embodiment, referring to Figure 1 , the reference positioning member 100 is a reference positioning plate, the reference positioning plate includes a front panel surface 110, a back panel surface, and a side surface 120. The back panel surface is used to fit with the surface of the cabinet board 20 to be punched, and a plurality of scale lines 101 are provided on the side surface 120; the hole position positioning member 200 is a hole position positioning plate, and the hole position positioning plate is movably arranged on the front panel surface 110 in the first direction and perpendicular to the front panel surface 110.

[0050] By making the back panel surface of the reference positioning plate fit the panel surface of the cabinet panel 20 to be drilled, a stable reference can be provided, ensuring that the measurement reference of the scale line 101 is accurate and reliable, thereby improving the accuracy of the drilling position. A plurality of scale lines 101 are provided on the side surface 120, enabling the staff to clearly and directly read the scale when adjusting the hole position positioning plate, facilitating accurate position adjustment. The hole position positioning plate is movably arranged on the front panel surface 110 along the first direction and perpendicular to the front panel surface 110, allowing the staff to clearly observe the correspondence between the positioning mark 201 and the scale line 101 from multiple angles, facilitating fine adjustment.

[0051] In a possible embodiment, referring to Figure 1 , the connection between the hole position positioning plate and the front panel surface 110 has a preset distance from the edge of the front panel surface 110.

[0052] By making the connection between the hole position positioning plate and the front panel surface 110 have a preset distance from the edge of the front panel surface 110, the force distribution at the connection can be made more uniform, reducing concentrated stress, thereby enhancing the stability of the entire structure and extending the service life of the device. It can also provide more operating space for the staff when adjusting the hole position positioning plate, preventing the hand or operating tool from interfering with the edge of the front panel surface 110, making the adjustment process smoother, and avoiding the hole position positioning plate being affected by the unevenness or other factors of the front panel surface 110 edge during the adjustment process, thereby reducing the positioning error and improving the drilling accuracy.

[0053] In a possible embodiment, referring to Figure 1 , the hole position positioning plate is movably arranged on the front panel surface 110 along the first direction through the guiding structure 300.

[0054] Thus, the guiding structure 300 can ensure that the hole position positioning plate moves accurately along the preset first direction, avoiding deviation or shaking, making the movement of the hole position positioning plate smoother and easier, thereby improving the accuracy and precision of the drilling position. And the staff can adjust its position more conveniently and quickly, improving work efficiency. In addition, the guiding structure 300 can reduce the direct friction between the hole position positioning plate and the front panel surface 110, reducing component wear and extending the service life of the device. And each time of operation, due to the limitation of the guiding structure 300, the movement path of the hole position positioning plate is the same, which can ensure the consistency and repeatability of multiple drilling positionings. The staff does not need to pay too much attention to the movement direction and control force of the hole position positioning plate, and only needs to push along the guiding structure 300, reducing the operation difficulty and the requirements for the staff's skills.

[0055] In a possible embodiment, referring to Figure 1, the guiding structure 300 includes a first slide rail 310 disposed on the front panel and a first slider 320 slidably engaged with the first slide rail 310. The first slide rail 310 extends along a first direction, and the hole position positioning plate is disposed on the first slider 320.

[0056] Thus, the cooperation between the first slide rail 310 and the first slider 320 can provide precise linear guidance, ensuring that the hole position positioning plate moves strictly along the first direction, making the sliding of the hole position positioning plate smoother and more stable, reducing jamming and bouncing, contributing to more accurate positioning, improving the accuracy of the punching position, and effectively reducing the frictional resistance during the sliding process. The staff can more easily adjust the position of the hole position positioning plate. In addition, the combined structure of the slide rail and the slider is relatively simple, easy to manufacture and install, and also has high reliability and stability.

[0057] Of course, the guiding structure 300 is not limited to the above form. The guiding structure 300 can also be a guiding column and a guiding sleeve: the guiding column is fixed on the front panel, and the guiding sleeve is installed on the hole position positioning plate to achieve the guiding function; a roller and a guide rail: rollers are installed on the hole position positioning plate and roll along the fixed guide rail to achieve guiding movement; a ball screw: the rotation of the screw drives the hole position positioning plate to move precisely along the axis direction of the screw, etc. Those skilled in the art should be aware of this.

[0058] In a possible embodiment, refer to Figure 3 , the first slide rail 310 is a dovetail groove, and the first slider 320 is a dovetail slider that cooperates with this dovetail groove to prevent the first slider 320 from disengaging from the front panel surface 110 in a direction perpendicular to the guiding direction.

[0059] In a possible embodiment, refer to Figure 1 , along the first direction, the end of the first slide rail 310 corresponds to the 0 scale line 101, so that when the reference positioning member 100 is disposed on the cabinet board 20 to be punched, the end of the first slide rail 310 can abut against the inner top plate of the cabinet 2 to achieve the positioning of the reference positioning member 100, without the need for the staff to align it with the naked eye, the operation is simple, and the positioning is accurate.

[0060] In a possible embodiment, refer to Figure 1 , a limiting structure 400 is disposed on the front panel surface 110. The limiting structure 400 is used to limit the hole position positioning plate in the first direction to prevent the hole position positioning plate from disengaging from the front panel surface 110.

[0061] By providing a limiting structure 400 on the front panel surface 110, the limiting structure 400 is used to limit the hole position positioning plate in the first direction, which can prevent the hole position positioning plate from accidentally detaching from the front panel surface 110, ensure the smooth and continuous progress of the work, reduce the risk of accidental injury caused by component detachment, and moreover, can ensure that the hole position positioning plate always moves on the front panel surface 110 without affecting the subsequent drilling and positioning accuracy due to detachment.

[0062] In a possible embodiment, referring to Figure 1 , a limiting groove is provided on the front panel surface 110. The limiting sliding groove extends in the first direction, and the length of the limiting groove is equal to the length of the first sliding rail 310. The first slider 320 is slidably arranged in the limiting groove in the first direction, and both ends of the first slider 320 in the first direction are in blocking cooperation with the groove walls of the limiting groove to limit the hole position positioning plate on the front panel surface 110.

[0063] Of course, the limiting structure 400 is not limited to the above structure. The limiting structure 400 can also be a fixed stopper provided at the end of the front panel surface 110. When the hole position positioning plate moves to the extreme position, it will be blocked by the stopper, or a travel switch is installed at the extreme position of the front panel surface 110. When the hole position positioning plate touches the travel switch, a signal is triggered to stop its continued movement; or a magnet is provided at the extreme position of the front panel surface 110. The hole position positioning plate is made of a magnetizable material and is magnetically attracted and stops moving when approaching the extreme position. Any form of limiting structure 400 is not limited herein.

[0064] In a possible embodiment, referring to Figure 4 , referring to the figure, the hole position positioning plate includes a first positioning plate 210 and a second positioning plate 220 arranged in a stacked manner. The first positioning plate 210 is movably arranged on the front panel surface 110 in the first direction, and the second positioning plate 220 can move relative to the first positioning plate 210 in a second direction perpendicular to the first direction, and both the first direction and the second direction are parallel to the plate surface direction of the hole position positioning plate.

[0065] Among them, the second direction is Figure 4 the direction indicated by the arrow Y in

[0066] Thus, adjustments can be made in two mutually perpendicular directions, so as to more accurately determine the position of the hole on the plane. For the cabinet board 20 to be drilled with different shapes, sizes and layouts, it can more flexibly adapt to and position the drilling position, meet more complex and diverse drilling requirements, and through fine-tuning in two directions, the hole position can be more accurately aligned with the required position, reducing the error caused by the limitation of single-direction adjustment.

[0067] Exemplarily, if the door panel 21 is embedded, the second positioning plate 220 can be moved one gear towards the interior space of the cabinet 2 in the second direction, so as to adjust the depth of the position to be drilled towards the interior space of the cabinet 2.

[0068] In a possible embodiment, referring to Figure 5 , a second slide rail 2101 is provided on the first positioning plate 210, the second slide rail 2101 extends along the second direction, a second slider 2201 is provided on the second positioning plate 220, and the second slider 2201 is slidably engaged with the second slide rail 2101.

[0069] By providing the second slide rail 2101 on the first positioning plate 210, the second slide rail 2101 extends along the second direction, the second slider 2201 is provided on the second positioning plate 220, and the second slider 2201 is slidably engaged with the second slide rail 2101, it is possible to ensure that the second positioning plate 220 moves along the accurate second direction by the cooperation of the second slide rail 2101 and the second slider 2201, making the movement of the second positioning plate 220 smoother, reducing jitter and deviation, contributing to more accurate positioning to improve the accuracy of hole position positioning, and also being able to effectively reduce the frictional resistance during the movement, making the adjustment easier and more labor-saving.

[0070] In a possible embodiment, referring to Figure 5 , the positioning mark 201 includes a strip-shaped through hole 2011 provided on the first positioning plate 210 and a positioning through hole 2012 provided on the second positioning plate 220. The length direction of the strip-shaped through hole is parallel to the second direction. Along the direction perpendicular to the plate surface of the second positioning plate 220, the projection of the positioning through hole is located within the strip-shaped through hole.

[0071] Thus, the setting of the strip-shaped through hole 2011 provides a large adjustable range for the positioning through hole 2012 in the second direction, can adapt to a wider range of drilling position requirements, and through the cooperation of the positioning through hole 2012 and the strip-shaped through hole 2011, it is convenient to mark on the cabinet board 20 to determine the final drilling position.

[0072] In a possible embodiment, referring to Figure 5 , there are two positioning through holes 2012, the two positioning through holes 2012 are arranged at intervals along the first direction, the positioning mark 201 further includes a center line 2013 provided on the center lines of the two positioning through holes 2012 along the first direction, and the center line 2013 is used to correspond to a preset scale line. Thus, by simply making the center line 2013 correspond to the preset scale line, the two positioning through holes 2012 can reach the position to be drilled, improving the work efficiency.

[0073] In a possible embodiment, referring to Figure 3 and Figure 5, the punching positioning device 1 further includes a locking structure 500, and the locking structure 500 is used to lock the hole position positioning member 200 to the reference positioning member 100.

[0074] Thus, after the adjustment of the hole position positioning member 200 is completed, the locking structure 500 can lock the hole position positioning member 200 to the reference positioning member 100, preventing it from moving due to factors such as vibration and accidental touch during the punching process, avoiding punching deviation caused by the accidental movement of the hole position positioning member 200, and thus ensuring the accuracy and stability of the punching position.

[0075] In a possible embodiment, referring to Figure 3 , the locking structure 500 includes a movable locking member provided on the hole position positioning member 200 and a locking groove 520 provided on the reference positioning member 100. There are multiple locking grooves 520, and the multiple locking grooves 520 are arranged at intervals in the vertical direction. Each locking groove 520 corresponds to a preset scale line. When the locking structure 500 is in the locked state, the movable locking member extends into the locking groove 520 and is engaged with the locking groove 520 in a snap-fit manner. When the locking structure 500 is in the unlocked state, the movable locking member 510 withdraws from the locking groove 520 to release the snap-fit between the movable locking member 510 and the locking groove 520.

[0076] Thus, the hole position positioning member 200 can be locked at different preset heights, adapting to various punching height requirements, increasing the versatility of the device. And each locking groove 520 corresponds to a specific preset scale line, which can accurately fix the hole position positioning member 200 at the required height position, ensuring the accuracy of the punching height. Also, when the height needs to be adjusted, only the movable locking member 510 needs to be withdrawn from the current locking groove 520, moved to the locking groove 520 corresponding to the appropriate height and then locked. When the locking structure 500 is in the locked state, the snap-fit between the movable locking member 510 and the locking groove 520 can provide a stable connection, preventing the hole position positioning member 200 from shaking or displacing in the vertical direction, enabling the staff to quickly complete the height adjustment and locking, reducing the time consumed in the positioning and fixing process, and thus improving the overall work efficiency.

[0077] Among them, the locking structure 500 can be to set corresponding threaded holes on the hole position positioning member 200 and the reference positioning member 100, and fix the relative positions of the two by tightening bolts; it can also be to set corresponding jacks on the hole position positioning member 200 and the reference positioning member 100, and insert pins to achieve locking; it can also be to install magnets at the contact parts of the hole position positioning member 200 and the reference positioning member 100, and achieve locking through magnetic adsorption and other forms, which should be known to those skilled in the art.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the punching positioning device of the present application, rather than limiting it; although the punching positioning device of the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
