Description

Technical Field

[0001] This utility model relates to a punching tool, and more specifically, to a punching aid. Background Technology

[0002] Drilling aids help position the drill during drilling, ensuring accuracy and quality. When drilling thinner objects such as sheets or belts, these aids can improve efficiency. However, existing drilling aids are relatively complex in structure and operation, and their efficiency needs further improvement.

[0003] For example, Chinese Patent Publication No. CN217168834U, published on August 12, 2022, is entitled "A Drilling Auxiliary Device." It includes a main body with a notch. A measuring block is slidably connected to the notch. A stop portion is provided at one end of the measuring block opposite to the notch, perpendicular to the measuring block. A positioning hole is obliquely arranged on the side of the main body, penetrating the main body. Graduations are provided on both the upper and lower surfaces of the measuring block. The main body also has a placement portion for holding a drill bit. The placement portion includes a holding cavity and a first groove on the main body, and a third groove on the stop portion. Third scales are provided on both sides of the holding cavity. This drilling auxiliary device can measure the thickness of the wooden board to be drilled and the length of the drill bit. Then, based on the thickness of the wooden board and the length of the drill bit, the distance between the stop portion and the main body is adjusted, thus achieving the positioning of the drilling position and preventing the drill bit from penetrating the wooden board during drilling due to its excessive length. However, this solution has a complex structure, complicated auxiliary positioning operations, and low drilling efficiency. Utility Model Content

[0004] This invention overcomes the problems of complex structure and complicated drilling positioning operation of existing drilling aids, and provides a drilling aid with simple structure and simple positioning operation, which can realize rapid drilling operation, and is especially suitable for assisting in drilling thinner objects.

[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a drilling aid, comprising a main body, at least two clamping parts on one side of the main body, the length direction of the clamping parts being perpendicular to the length direction of the main body, and a positioning part on the side of the main body away from the clamping parts, the positioning part having a positioning block. In this solution, the clamping parts can be used to clamp the object to be drilled. The perpendicularity between the clamping parts and the main body ensures that the clamping parts clamp the object to be drilled in the width direction, and then achieve auxiliary positioning of the drilling position in the length direction; the positioning block on the positioning part can achieve positioning on the object to be drilled, ensuring the positioning accuracy of the drilling aid and thus improving the drilling quality. In use, it is only necessary to use the positioning part for positioning and then determine the length and width positions of the hole along the length directions of the main body and the clamping parts respectively to achieve fixed-point drilling, greatly improving drilling efficiency.

[0006] Preferably, the clamping part includes an elastic sheet, which is integrally formed with the main body into a U-shaped structure. The elastic sheet can work with the main body to clamp the object to be punched, achieving stable positioning and ensuring punching quality; furthermore, the use of the elastic sheet makes it easier to adjust the relative position between the punching aid and the object to be punched.

[0007] Preferably, the positioning part and the clamping part are aligned, one end of the elastic piece extends to the location of the positioning block, and the positioning block faces the elastic piece. This alignment of the positioning part and the clamping part facilitates the manufacturing of the drilling aid, and the extension of the elastic piece on the clamping part to the location of the positioning block protects the positioning block, preventing wear or obstruction of its use.

[0008] Preferably, a first scale is provided along the length of the main body, and the positioning part is located at the starting end of the first scale. The first scale can measure the accuracy of the hole position in the length direction on the object to be drilled, ensuring the accuracy of the drilling position in one dimension. Arranging the positioning part at the starting end of the first scale is beneficial for the positioning and calibration of the hole position.

[0009] Preferably, a second scale is provided along the length of the clamping part, with the starting end of the second scale close to the side of the first scale. The second scale can measure the width direction accuracy of the hole point on the object to be punched, ensuring the accuracy of the punching position in one dimension.

[0010] Preferably, the main body is provided with a reinforcing portion, which is arranged away from the first scale, and the two sides of the reinforcing portion transition to the main body with rounded corners. The reinforcing portion can enhance the structural strength of the main body and also increase the area of ​​the main body. When the clamping portion clamps the object to be punched, it can cooperate with the clamping portion to increase the contact area of ​​the object to be punched, thereby improving the clamping degree of the object to be punched and improving the punching quality.

[0011] Preferably, the width dimension of the reinforcing part is smaller than the length dimension of the clamping part. The fact that the width dimension of the reinforcing part does not exceed the length dimension of the clamping part effectively limits the overall size of the drilling aid, making it compact and portable.

[0012] Preferably, the reinforcing part is provided with a decorative groove, which is located on the same side as the first scale. The decorative groove can be used to attach labels or nameplates, which not only improves the decorative effect but also serves as a product promotion tool.

[0013] Preferably, one end of the main body is provided with a hole diameter measuring section, which has several measuring columns with different radial dimensions and specifications marked on them. The hole diameter measuring section can be used to measure the size of holes, both existing and newly drilled. The multiple sets of different measuring columns on the hole diameter measuring section can measure hole diameters of various sizes, thus realizing the multi-functionality of the drilling aid.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) The structure of this solution is simple, the positioning operation is simple, and the drilling quality is high; (2) It can realize rapid drilling operation, especially suitable for assisting in drilling thinner objects; (3) It has good structural strength and can achieve stable clamping and positioning effect; (4) The production cost is low, it is easy to produce and implement, and it is small, portable and convenient to use.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: As Figures 1 to 5 A punching aid, as shown, includes a main body 1, which is elongated. Two clamping parts, a first clamping part 2.1 and a second clamping part 2.2, are arranged at both ends of the main body 1, perpendicular to its length. The length of the first clamping part 2.1 is greater than that of the second clamping part 2.2. Both the first clamping part 2.1 and the second clamping part 2.2 are integrally formed with the main body 1. A positioning part 3 is provided on the side of the main body 1 away from the clamping parts, and the positioning part 3 is located at the position of the first clamping part 2.1. In this design, the first clamping part 2.1 and the second clamping part 2.2 can clamp the object to be punched. The fact that both the first clamping part 2.1 and the second clamping part 2.2 are perpendicular to the main body 1 ensures that the first clamping part 2.1 and the second clamping part 2.2 clamp the object to be punched in the width direction and then provide auxiliary positioning for the punching position in the length direction. The positioning part 3 can position the object to be punched, ensuring the positioning accuracy of the punching aid and thus improving the punching quality. In use, it is only necessary to use the positioning part 3 for positioning, and then determine the length and width of the hole along the length direction of the main body part 1 and the clamping part respectively to achieve fixed-point drilling, which greatly improves the drilling efficiency. In this embodiment, the belt 9 is used as the object to be drilled.

[0023] Specifically, the first clamping part 2.1 includes a first elastic piece 2.11, which is bent into an inverted U-shape and is close to the surface of the main body 1, thereby elastically clamping the belt 9 between the first elastic piece 2.11 and the main body 1. At the bend of the first clamping part 2.1, the vertical distance between the first elastic piece 2.11 and the main body 1 is relatively large, giving the first clamping part 2.1 good structural strength at the bend and making it less prone to breakage. The second clamping part 2.2 includes a second elastic piece 2.21, which is bent into an inverted U-shape and is close to the surface of the main body 1, thereby elastically clamping the belt 9 between the second elastic piece 2.21 and the main body 1. At the bend of the second clamping part 2.2, the vertical distance between the second elastic piece 2.21 and the main body 1 is relatively large, giving the second clamping part 2.2 good structural strength at the bend and making it less prone to breakage.

[0024] The positioning part 3 is located on the side of the main body 1 away from the first clamping part 2.1, and the positioning part 3 is located along the length of the first clamping part 2.1, that is, the positioning part 3 protrudes from the main body 1; the positioning part 3 is provided with a positioning block 3.1, which is a conical protrusion structure, and the conical end of the positioning block 3.1 faces the position of the first elastic piece 2.11; that is, the length of the first elastic piece 2.11 of the first clamping part 2.1 extends to the position of the positioning block 3.1. In this way, the first elastic piece 2.11 can cover the positioning block 3.1, which not only protects the positioning block 3.1 and prevents it from wearing out, but also prevents the conical structure of the positioning block 3.1 from puncturing the user; in addition, since the end of the first elastic piece 2.11 is close to the main body 1, the distance between the first elastic piece 2.11 and the conical end of the positioning block 3.1 is smaller, which can stably position the positioning point on the belt 9 and prevent the positioning from falling off.

[0025] A first scale 4 is provided on the main body 1, and a second scale 5 is provided on both the first clamping part 2.1 and the second clamping part 2.2. The first scale 4 is arranged along the length direction of the main body 1 with a range of 70mm, and the second scale 5 is distributed along the length direction of the clamping part with a range of 10mm. The 0 position of the first scale 4 is located on one side of the first clamping part 2.1, that is, at the position corresponding to the positioning block 3.1, and the 0 position of the second scale 5 is located at the connection position between the clamping part and the main body 1. There are two sets of second scale 5. By using the two sets of second scale 5, it is possible to detect or visually see whether the two ends (in the length direction) of the belt 9 are in a horizontal state. Therefore, the clamping part is provided with at least two sets, which can not only ensure the clamping degree of the belt 9, but also indicate whether the punching position is horizontal through the second scale 5.

[0026] The usage method of this solution is as follows (e.g.) Figure 5 (As shown).

[0027] First, an initial positioning hole needs to be drilled on the belt 9. The position of the initial positioning hole can be determined by measuring the first scale 4 on the main body 1 and the second scale 5 on the clamping part. After the initial positioning hole is drilled, the belt 9 is placed in the inverted U-shaped groove between the first clamping part 2.1 and the second clamping part 2.2 and clamped by the first clamping part 2.1 and the second clamping part 2.2. At the same time, the positioning block 3.1 on the positioning part 3 passes through the initial positioning hole to achieve positioning. In this way, the main body 1 can rotate and fine-tune around the positioning block 3.1 to a certain extent so that the scale values ​​of the belt 9 on the first clamping part 2.1 and the second clamping part 2.2 are the same, thereby ensuring that the levelness of the belt 9 is the same as that of the main body 1. The width coordinate of the hole position can be determined by the second scale 5 on the clamping part (composed of the value on the second scale 5 plus the width of the main body 1). Then, the length coordinate of the hole position can be determined by the first scale 4 on the main body 1 to completely locate the drilling position on the belt 9. Finally, a hole punch is used to drill the hole at the designated position.

[0028] It should be noted that the drilling position is located to one side of the first scale mark 4. This ensures that the drilled hole is aligned with the initial positioning hole, and the second drilled hole can be used as the next positioning hole. Simply move the positioning block 3.1 onto the second drilled hole to serve as the starting point for the third hole; subsequent drilling can follow the same pattern. Thus, the maximum range of the first scale mark 4 only needs to satisfy the minimum distance between the two holes, allowing the drilling aid to be designed to be compact and portable.

[0029] Example 2: Figures 1 to 5 A punching aid, as shown, includes a main body 1, which is elongated. Two clamping parts, a first clamping part 2.1 and a second clamping part 2.2, are arranged at both ends of the main body 1, perpendicular to its length. The length of the first clamping part 2.1 is greater than that of the second clamping part 2.2. Both the first clamping part 2.1 and the second clamping part 2.2 are integrally formed with the main body 1. A positioning part 3 is provided on the side of the main body 1 away from the clamping parts, and the positioning part 3 is located at the position of the first clamping part 2.1. In this design, the first clamping part 2.1 and the second clamping part 2.2 can clamp the object to be punched. The fact that both the first clamping part 2.1 and the second clamping part 2.2 are perpendicular to the main body 1 ensures that the first clamping part 2.1 and the second clamping part 2.2 clamp the object to be punched in the width direction and then provide auxiliary positioning for the punching position in the length direction. The positioning part 3 can position the object to be punched, ensuring the positioning accuracy of the punching aid and thus improving the punching quality. In use, it is only necessary to use the positioning part 3 for positioning, and then determine the length and width of the hole along the length direction of the main body part 1 and the clamping part respectively to achieve fixed-point drilling, which greatly improves the drilling efficiency. In this embodiment, the belt 9 is used as the object to be drilled.

[0030] Specifically, the first clamping part 2.1 includes a first elastic piece 2.11, which is bent into an inverted U-shape and is close to the surface of the main body 1, thereby elastically clamping the belt 9 between the first elastic piece 2.11 and the main body 1. At the bend of the first clamping part 2.1, the vertical distance between the first elastic piece 2.11 and the main body 1 is relatively large, giving the first clamping part 2.1 good structural strength at the bend and making it less prone to breakage. The second clamping part 2.2 includes a second elastic piece 2.21, which is bent into an inverted U-shape and is close to the surface of the main body 1, thereby elastically clamping the belt 9 between the second elastic piece 2.21 and the main body 1. At the bend of the second clamping part 2.2, the vertical distance between the second elastic piece 2.21 and the main body 1 is relatively large, giving the second clamping part 2.2 good structural strength at the bend and making it less prone to breakage.

[0031] The positioning part 3 is located on the side of the main body 1 away from the first clamping part 2.1, and the positioning part 3 is located along the length of the first clamping part 2.1, that is, the positioning part 3 protrudes from the main body 1; the positioning part 3 is provided with a positioning block 3.1, which is a conical protrusion structure, and the conical end of the positioning block 3.1 faces the position of the first elastic piece 2.11; that is, the length of the first elastic piece 2.11 of the first clamping part 2.1 extends to the position of the positioning block 3.1. In this way, the first elastic piece 2.11 can cover the positioning block 3.1, which not only protects the positioning block 3.1 and prevents it from wearing out, but also prevents the conical structure of the positioning block 3.1 from puncturing the user; in addition, since the end of the first elastic piece 2.11 is close to the main body 1, the distance between the first elastic piece 2.11 and the conical end of the positioning block 3.1 is smaller, which can stably position the positioning point on the belt 9 and prevent the positioning from falling off.

[0032] A first scale 4 is provided on the main body 1, and a second scale 5 is provided on both the first clamping part 2.1 and the second clamping part 2.2. The first scale 4 is arranged along the length direction of the main body 1 with a range of 70mm, and the second scale 5 is distributed along the length direction of the clamping part with a range of 10mm. The 0 position of the first scale 4 is located on one side of the first clamping part 2.1, that is, at the position corresponding to the positioning block 3.1, and the 0 position of the second scale 5 is located at the connection position between the clamping part and the main body 1. There are two sets of second scale 5. By using the two sets of second scale 5, it is possible to detect or visually see whether the two ends (in the length direction) of the belt 9 are in a horizontal state. Therefore, the clamping part is provided with at least two sets, which can not only ensure the clamping degree of the belt 9, but also indicate whether the punching position is horizontal through the second scale 5.

[0033] A reinforcing part 6 is provided on the main body 1, located between the first clamping part 2.1 and the second clamping part 2.2. The reinforcing part 6 is trapezoidal in shape and has the same thickness as the main body 1. The reinforcing part 6 enhances the structural strength of the main body 1 and also increases its area. When the clamping part clamps the belt 9, it can work together to increase the contact area with the belt 9, thereby improving the clamping degree of the belt 9 and improving the drilling quality. The reinforcing part 6 and the main body 1 are connected by a rounded corner, which can reduce stress concentration between the main body 1 and the reinforcing part 6 and provide a better user experience. The width of the reinforcing part 6 does not exceed the length of the clamping part, which effectively limits the overall size of the drilling aid, making the drilling aid compact and portable. A decorative groove 7 is also provided on the reinforcing part 6. The decorative groove 7 is a shallow groove structure located on the same surface as the first scale 4. It is mainly used to affix logos or specification nameplates, which not only enhances the decorative effect but also serves as product promotion.

[0034] An aperture measuring section 8 is also provided at one end of the main body 1. The aperture measuring section 8 is located at the end of the main body 1 along its length. In this embodiment, the aperture measuring section 8 is located on one side of the first clamping section 2.1. The aperture measuring section 8 has a stepped shaft structure. From the near end to the far end of the main body 1, the radial dimension of the aperture measuring section 8 gradually decreases, forming measuring columns of different specifications. Each measuring column is marked with a specification mark corresponding to the radial dimension. The aperture measuring section 8 is used to measure the size of the aperture. It can measure existing apertures or newly drilled holes. It should be noted that the aperture measuring section 8 can also use a continuously changing aperture. In this case, the aperture measuring section 8 is a continuous conical surface, and the aperture size can also be indicated by a scale on the conical surface.

[0035] The usage method of this solution is as follows (e.g.) Figure 5 (As shown).

[0036] First, an initial positioning hole needs to be drilled on the belt 9. The position of the initial positioning hole can be determined by measuring the first scale 4 on the main body 1 and the second scale 5 on the clamping part. After the initial positioning hole is drilled, the belt 9 is placed in the inverted U-shaped groove between the first clamping part 2.1 and the second clamping part 2.2 and clamped by the first clamping part 2.1 and the second clamping part 2.2. At the same time, the positioning block 3.1 on the positioning part 3 passes through the initial positioning hole to achieve positioning. In this way, the main body 1 can rotate and fine-tune around the positioning block 3.1 to a certain extent so that the scale values ​​of the belt 9 on the first clamping part 2.1 and the second clamping part 2.2 are the same, thereby ensuring that the levelness of the belt 9 is the same as that of the main body 1. The width coordinate of the hole position can be determined by the second scale 5 on the clamping part (composed of the value on the second scale 5 plus the width of the main body 1). Then, the length coordinate of the hole position can be determined by the first scale 4 on the main body 1 to completely locate the drilling position on the belt 9. Finally, a hole punch is used to drill the hole at the designated position.

[0037] When measuring the diameter of a hole using the aperture measuring part 8, simply insert the aperture measuring part 8 into the hole to be measured until the aperture measuring part 8 is completely in contact with the hole to be measured. At this point, the specification marking on the aperture measuring part 8 is the diameter of the hole to be measured.

[0038] It should be noted that the drilling position is located to one side of the first scale mark 4. This ensures that the drilled hole is aligned with the initial positioning hole, and the second drilled hole can be used as the next positioning hole. Simply move the positioning block 3.1 onto the second drilled hole to serve as the starting point for the third hole; subsequent drilling can follow the same pattern. Thus, the maximum range of the first scale mark 4 only needs to satisfy the minimum distance between the two holes, allowing the drilling aid to be designed to be compact and portable.
