Abstract
Description
Technical Field
[0001] The present application relates to the technical field of household products, and in particular to a positioning tool for an inner arc door opening. Background Art
[0002] In the existing furniture industry, door panels need to be drilled and then hinges are installed to fix them on the door frames. Door panels are usually flat doors, and holes can be drilled directly on the door panels, which makes it convenient for workers to position and drill holes in the flat door panels. However, when drilling holes in door panels for inner arc doors, existing drilling tools and hole arrangement equipment cannot drill holes for the inner arc doors normally. First, lines are drawn on the back of the inner arc door according to process requirements, and the positions where holes need to be drilled are marked. A drilling tool is assembled on the electric drill, and the drilling tool is aligned with the marked positions to drill holes. However, due to the particularity of the inner arc door, the surface of the inner arc door has a certain curvature. When workers drill holes in the arc door directly, it is easy for the hole position to shift due to slipping, resulting in low drilling accuracy of the hole position, which affects the subsequent normal installation of the inner arc door. Utility Model Content
[0003] The embodiment of the present application provides a positioning tool for opening a hole in an inner arc door, which can be used for positioning and opening a hole in an inner arc door and has high opening accuracy.
[0004] An embodiment of the present application provides a positioning tool for opening a hole in an inner arc door, the positioning tool comprising a supporting plate and a positioning plate, for supporting against the inner side wall of the inner arc door; the positioning plate is vertically connected to the supporting plate, the positioning plate has a fitting surface matching the curvature of the inner arc door, the fitting surface is used to abut against the surface of the inner arc door where the hole is to be opened; wherein a positioning hole is opened through the positioning plate along the thickness direction thereof, the positioning hole is used to allow an electric drill to pass through to perform a hole opening operation on the inner arc door.
[0005] In the present scheme, by setting the abutment plate in the positioning tool, the abutment plate can be abutted against the inner side wall of the inner arc door, so that the positioning tool can remain relatively still under the resisting action of the inner side of the inner arc door, and then the positioning plate is set perpendicular to the abutment plate, and the positioning plate has a fitting surface matching the curvature of the inner arc door, so that the positioning plate can be fitted to the surface of the inner arc door where the hole is to be opened with the help of the fitting surface, and the surface of the inner arc door where the hole is to be opened is marked in advance, and the position of the hole to be opened is marked, and then the positioning hole in the positioning plate is made to coincide with the position of the hole, and the hole opening knife on the electric drill can directly open the hole on the inner arc door through the positioning hole, and it is only necessary to ensure that the position of the positioning tool is relatively fixed to the inner arc door, then the positioning hole on the positioning plate can provide positioning and limiting effects on the electric drill, thereby improving the accuracy of the hole opening, avoiding the shaking of the tool during the processing and affecting the accuracy of the hole opening, simplifying the operation difficulty of the staff, and improving the efficiency of the tool hole opening.
[0006] In some embodiments, there are multiple positioning holes.
[0007] In the above technical solution, by setting the number of positioning holes to multiple, multiple holes can be drilled after a one-time calibration, without the need to position each hole each time it is drilled, thereby improving the drilling efficiency.
[0008] In some embodiments, the positioning tool further includes a clamping unit, which is used to apply pressure to the positioning plate so that the positioning plate is clamped and positioned on the inner arc door.
[0009] In the above technical solution, the positioning plate is clamped and positioned on the inner arc door by using a clamping unit, so that the staff does not need to free their hands to position the abutment plate on the inner arc door, which reduces the operating difficulty of the staff and facilitates the staff to open holes more accurately.
[0010] In some embodiments, the clamping unit includes a clamping member and a locking member. The clamping member is composed of a bottom wall and two side walls connected to opposite sides of the bottom wall. The clamping member forms a U-shaped clamping groove. The clamping member is clamped by two side walls respectively on the positioning plate and the side of the inner arc door facing away from the positioning plate. The locking member is threadedly engaged with the clamping member, and one end of the locking member located in the clamping groove is pressed against the positioning plate or the side of the inner arc door facing away from the positioning plate.
[0011] In the above technical solution, by adopting the clamping unit as a clamping member and a locking member, the two side walls of the clamping member can be clamped on the positioning plate and the side of the inner arc door facing away from the positioning plate respectively, and then the locking member is threadedly matched with the clamping member, and by rotating the locking member, one end of the locking member located in the clamping groove is abutted against the positioning plate or the side of the inner arc door facing away from the positioning plate, thereby fixing the positioning plate on the inner arc door, so that the position of the positioning plate is relatively fixed to the inner arc door.
[0012] In some embodiments, one end of the locking member located in the clamping groove abuts against the positioning plate.
[0013] In the above technical solution, one end of the locking member located in the clamping groove is held against the positioning plate, so that the locking member directly contacts the positioning plate and does not contact the inner arc door, thereby preventing the locking member from causing damage to the inner arc door.
[0014] In some embodiments, the number of the locking members is set to be multiple, and the multiple locking members are distributed at intervals on the same side of the clamping member.
[0015] In the above technical solution, through the cooperation of multiple locking members, the multiple locking members jointly apply a clamping force to the positioning plate, and the clamping unit has a better effect of clamping and fixing the positioning plate.
[0016] In some embodiments, the number of the locking members is set to be multiple, and the multiple locking members are respectively located on two opposite sides of the clamping member.
[0017] In the above technical solution, the positioning plate can also be clamped and fixed by multiple locking members located on opposite sides of the clamping member, that is, the multiple locking members respectively abut against the positioning plate and the side of the inner arc door away from the positioning plate.
[0018] In some embodiments, a flexible contact portion is disposed at one end of the locking member located in the clamping groove.
[0019] In the above technical solution, a flexible contact portion is provided at one end of the locking member located in the clamping groove, so that the locking member contacts the positioning plate or the inner arc door through the contact portion, which can reduce the probability of the locking member causing an indentation on the surface of the positioning plate or the inner arc door, and play a certain protective role on the positioning plate or the inner arc door. In addition, the provision of the contact portion prevents the locking member from separating from the clamping plate, improves the integrity of the clamping unit, and reduces the probability of the locking member being lost.
[0020] In some embodiments, the clamping unit includes a clamping plate and a locking member. The clamping plate is vertically connected to the abutment plate. The clamping plate and the positioning plate are spaced apart and located on the same side of the abutment plate. The locking member is threadedly engaged with the clamping plate, and one end of the locking member is abutted against the inner arc door.
[0021] In the above technical solution, the clamping plate is vertically connected to the abutting plate to form a whole with the abutting plate. In this way, only the locking piece needs to be rotated to achieve the clamping and positioning of the clamping plate and the positioning plate on both sides of the inner arc door, which is simple to operate and convenient to position.
[0022] In some embodiments, the abutment plate, the positioning plate and the clamping plate are integrally formed.
[0023] In the above technical solution, the positioning tooling has a stronger integrity by forming the abutting plate, the positioning plate and the clamping plate in one piece.
[0024] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Example
[0038] In related technologies, such as Figure 1 As shown, the staff marks the back of the inner arc door 200 according to the process requirements, marks the marked position 201 where the hole needs to be drilled, assembles a drilling tool on the hand drill 300, and aligns the drilling tool with the marked position 201 to drill the hole.
[0039] The present application embodiment provides a positioning tool for an inner arc door opening, see Figures 2 to 5 The positioning tooling includes a supporting plate 10 and a positioning plate 20, which are used to abut against the inner side wall 311 of the inner arc door 200; the positioning plate 20 is vertically connected to the supporting plate 10, and the positioning plate 20 has a fitting surface matching the curvature of the inner arc door 200, and the fitting surface is used to abut against the surface of the inner arc door 200 where the hole is to be opened; wherein, a positioning hole 21 is opened through the positioning plate 20 along the thickness direction thereof, and the positioning hole 21 is used to allow an electric drill to pass through to perform a hole opening operation on the inner arc door 200.
[0040] In this solution, by setting the abutment plate 10 in the positioning tool, the abutment plate 10 can be abutted against the inner side wall 311 of the inner arc door 200, so that the positioning tool remains relatively still under the resistance of the inner side of the inner arc door 200, and then the positioning plate 20 is set perpendicular to the abutment plate 10, and the positioning plate 20 has a fitting surface that matches the curvature of the inner arc door 200, so that the positioning plate 20 can be fitted to the surface of the inner arc door 200 where the hole is to be opened with the help of the fitting surface, and the surface of the inner arc door 200 where the hole is to be opened is marked in advance, and the mark of the hole to be opened is marked. Note the position 201, and then make the positioning hole 21 in the positioning plate 20 coincide with the position of the hole. The hole-opening tool on the electric drill 300 can directly open the hole on the inner arc door 200 by passing through the positioning hole 21. It is only necessary to ensure that the position of the positioning tool is relatively fixed to the inner arc door 200. Then the positioning hole 21 on the positioning plate 20 can provide positioning and limiting functions for the electric drill 300, thereby improving the accuracy of the hole opening, avoiding the shaking of the tool during the processing and affecting the accuracy of the hole opening, simplifying the operation difficulty of the staff, and improving the efficiency of the tool opening.
[0041] Among them, the same type of inner arc door 200 has the same curvature, and different types of inner arc door 200 may not have different curvatures, or the curvatures are not much different, or even the same. Generally speaking, different types of inner arc doors 200 of the same manufacturer generally have the same curvatures, and different types are reflected in the length, width and height. Therefore, a set of positioning tooling can be adapted to one or more types of inner arc doors 200. For punching inner arc doors 200 with different curvatures, multiple sets of positioning tooling can be pre-made, and the curvatures of the fitting surfaces of the positioning plates 20 of different types of positioning tooling are different to meet the punching requirements of inner arc doors 200 with different curvatures.
[0042] In some embodiments, there are multiple positioning holes 21. By setting the number of positioning holes 21 to multiple, multiple holes can be drilled after a one-time calibration, and positioning is not required every time a hole is drilled, thereby improving the drilling efficiency.
[0043] The number of the positioning holes 21 may be two, three or four, etc. In this embodiment, the number of the positioning holes 21 is set to two, and the two positioning holes 21 are spaced apart and distributed along the height direction of the inner arc door 200 .
[0044] The positioning tooling can be fixed relative to the inner arc door 200 manually or by a clamping unit 30 .
[0045] In some embodiments, see Figures 3 to 5The positioning tool also includes a clamping unit 30, which is used to apply pressure to the positioning plate 20 so that the positioning plate 20 is clamped and positioned on the inner arc door 200. By using the clamping unit 30 to clamp the positioning plate 20 on the inner arc door 200, the staff does not need to free up their hands to tightly position the abutting plate 10 on the inner arc door 200, which reduces the operating difficulty of the staff and facilitates the staff to open the hole more accurately.
[0046] The clamping unit 30 can be of various structures. For example, the clamping unit 30 can also be a clamping cylinder, which is fixed in position by the clamping cylinder, and the driving end of the clamping cylinder is pressed against the positioning plate 20, so that the position of the positioning plate 20 and the inner arc door 200 are fixed. Of course, the clamping unit 30 can also be a clamping member 31 or a clamping plate 33 structure, etc., which clamps the two sides of the inner arc door 200 connected to the positioning plate 20, so that the position of the positioning plate 20 and the inner arc door 200 are fixed.
[0047] In some embodiments, see Figure 3 and Figure 4 The clamping unit 30 includes a clamping member 31 and a locking member 32. The clamping member 31 is composed of a bottom wall 310 and two side walls 311 connected to the opposite sides of the bottom wall 310. The clamping member 31 forms a U-shaped clamping groove; the clamping member 31 is clamped by the two side walls 311 to the positioning plate 20 and the inner arc door 200 away from the positioning plate 20, respectively. The locking member 32 is threadedly matched with the clamping member 31, and one end of the locking member 32 located in the clamping groove is pressed against the positioning plate 20 or the inner arc door 200 away from the positioning plate 20. By adopting the clamping unit 30 as a clamping member 31 and a locking member 32, the two side walls 311 of the clamping member 31 can be clamped on the positioning plate 20 and the side of the inner arc door 200 facing away from the positioning plate 20 respectively, and then the locking member 32 is threadedly matched with the clamping member 31. By rotating the locking member 32, the end of the locking member 32 located in the clamping groove is abutted against the positioning plate 20 or the side of the inner arc door 200 facing away from the positioning plate 20, thereby fixing the positioning plate 20 on the inner arc door 200, so that the position of the positioning plate 20 is relatively fixed to the inner arc door 200.
[0048] Of course, when the positioning tool needs to be removed, it is only necessary to loosen the locking member 32 so that the locking member 32 is disengaged from the positioning plate 20 or the side of the inner arc door 200 away from the positioning plate 20 .
[0049] In some embodiments, one end of the locking member 32 located in the clamping groove abuts against the positioning plate 20. By abutting against the positioning plate 20 at one end of the locking member 32 located in the clamping groove, the locking member 32 directly contacts the positioning plate 20 and does not contact the inner arc door 200, so that the locking member 32 does not damage the inner arc door 200.
[0050] In some embodiments, the number of locking members 32 is set to be multiple, and the multiple locking members 32 are spaced and distributed on the same side of the clamping member 31. Through the cooperation of the multiple locking members 32, the multiple locking members 32 jointly apply a clamping force to the positioning plate 20, and the clamping unit 30 has a better effect of clamping and fixing the positioning plate 20.
[0051] In this embodiment, the number of the locking members 32 is two.
[0052] In some embodiments, the number of locking members 32 is set to be multiple, and the multiple locking members 32 are respectively located on opposite sides of the clamping member 31. By having the multiple locking members 32 respectively located on opposite sides of the clamping member 31, that is, the multiple locking members 32 respectively abut against the positioning plate 20 and the side of the inner arc door 200 away from the positioning plate 20, the positioning plate 20 can also be clamped and fixed.
[0053] In some embodiments, a flexible contact portion is provided at one end of the locking member 32 located in the clamping groove. By providing a flexible contact portion at one end of the locking member 32 located in the clamping groove, the locking member 32 contacts the positioning plate 20 or the inner arc door 200 through the contact portion, which can reduce the probability of the locking member 32 causing an indentation on the surface of the positioning plate 20 or the inner arc door 200, and play a certain protective role on the positioning plate 20 or the inner arc door 200. In addition, the provision of the contact portion prevents the locking member 32 from separating from the clamping plate 33, improves the integrity of the clamping unit 30, and reduces the probability of the locking member 32 being lost.
[0054] The material of the contact part may be rubber.
[0055] In some embodiments, see Figure 5 The clamping unit 30 includes a clamping plate 33 and a locking member 32. The clamping plate 33 is vertically connected to the abutting plate 10. The clamping plate 33 and the positioning plate 20 are spaced apart and located on the same side of the abutting plate 10. The locking member 32 is threadedly engaged with the clamping plate 33. One end of the locking member 32 abuts against the inner arc door 200. By vertically connecting the clamping plate 33 to the abutting plate 10 and forming a whole with the abutting plate 10, it is only necessary to rotate the locking member 32 to realize the clamping and positioning of the clamping plate 33 and the positioning plate 20 on both sides of the inner arc door 200, which is simple to operate and convenient to position.
[0056] In some embodiments, the abutting plate 10, the positioning plate 20 and the clamping plate 33 are integrally formed. By integrally forming the abutting plate 10, the positioning plate 20 and the clamping plate 33, the integrity of the positioning tool is enhanced.
[0057] Of course, the abutment plate can be movably arranged on the positioning plate along the first direction, and the first direction can be the width direction of the positioning plate, so that the position of the abutment plate and the positioning plate can be adjusted, which can meet the adaptive adjustment of the hole position of the inner arc door and has a wider range of applications.
[0058] Specifically, the positioning plate can be provided with a slide groove along the width direction, the abutting plate can be provided with a slider correspondingly, the abutting plate can be provided with a locking screw, the locking screw is matched with the abutting plate thread, one end of the locking screw is used to abut against the slide groove to prevent the abutting plate from sliding along the width direction of the positioning plate. In this way, the positioning plate and the abutting plate can move, and after the abutting plate is adjusted to the right position, it abuts against the bottom wall of the slide groove through the locking screw, thereby preventing the abutting plate from moving.
[0059] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.
[0060] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
