Description

Technical Field

[0001] The invention relates to a drilling jig and belongs to the technical field of mechanical processing. Background Art

[0002] In the mold processing industry, drilling is one of the commonly used processing techniques. The traditional mold drilling method usually requires the fitter to manually draw lines for positioning before drilling. This method is cumbersome and has the following problems: First, manual line drawing is prone to errors, resulting in drilling position deviation, affecting mold processing accuracy. Second, manual line drawing requires frequent mold flipping, especially when processing large molds, which may injure operators and cause mold damage during the flipping process. This manual operation is inefficient and increases processing time and labor costs.

[0003] The utility model patent application number in the prior art is: 201320450828.8, and its name is a drilling positioning mold, which includes a template and a mold base. A mold hole is set on the template, and an observation hole is set at the center of the template. Multiple mold holes can be set, and the number and size of the mold holes are set according to the number and size of holes required for drilling. The use of this positioning mold avoids the error caused by marking, and at the same time, greatly saves processing time and procedures. The drilling positioning mold of the utility model is simple to install and convenient for tool alignment, which improves production efficiency and processing accuracy. However, this solution can only be applied to one size type, and cannot be applied to multiple size types. If templates of different sizes need to be drilled at different positions, it is necessary to replace drilling positioning molds of different sizes, which not only increases costs, but also prolongs production time. Summary of the invention

[0004] The present invention proposes a drilling jig, the purpose of which is to provide a drilling jig that can adapt to templates of various sizes and types, so as to improve the precision and production efficiency of drilling, simplify the operation process, and also solve the problem of the traditional mold drilling method that usually draws lines manually for positioning before drilling. The present invention realizes a flexible and versatile drilling solution by setting positioning hole groups of different sizes on the jig body and fixing the template with magnets to meet the drilling needs of templates of different sizes in the production process.

[0005] The technical solution adopted by the present invention is a drilling jig, including a jig body and a magnet, wherein the magnet is located on the side where one corner of the jig body is located, and the jig body is provided with a plurality of positioning hole groups, each positioning hole group is used to locate the position of the required drilling hole of the template.

[0006] Furthermore, the magnet is fastened to the fixture body by countersunk screws.

[0007] Furthermore, a bushing is provided in the positioning hole group.

[0008] Furthermore, the positioning hole group includes four through holes that are equidistantly distributed.

[0009] Furthermore, the surface of the fixture body is provided with size numerical markings corresponding one to one to the through holes.

[0010] Furthermore, the magnets are arranged at intervals on the side where the fixture body is located.

[0011] Furthermore, handles are provided on both sides of the fixture body.

[0012] The present invention discloses a drilling jig, which has the beneficial effect that, compared with the prior art, a suitable positioning hole group is selected according to the size of a template and fixed by a magnet, and drilling from a specific positioning hole group can effectively avoid human errors, ensure drilling accuracy, simplify the operation process, shorten production time, reduce costs, and also avoid injuring operators and damaging the template.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In order to further understand the content of the present invention, this technical solution is further explained below in conjunction with specific implementation methods.

[0018] Example 1: Figure 1~2 As shown, this embodiment provides a drilling jig, including a jig body 1 and a magnet 4, wherein the magnet 4 is located on two sides where one corner of the jig body 1 is located, and the two sides are specifically the side surfaces of the jig body 1, rather than the upper surface and the lower surface of the jig body 1, and this angle is defined as a positioning reference angle. Furthermore, the magnets 4 are arranged at intervals on the two sides of the jig body 1 and each magnet 4 is fixed to the jig body 1 by a countersunk screw 8. Furthermore, the magnets 4 are evenly spaced on any side where the jig body 1 is located.

[0019] The jig body 1 is provided with a number of positioning hole groups, each positioning hole group is used to locate the position of the hole required to be drilled on the template 5. Specifically, each positioning hole group includes four equidistantly distributed through holes 2, that is, the four through holes 2 are distributed in a square, which are used to quickly determine the precise drilling position on the template 5. Each through hole 2 is inlaid with a bushing 3, and the bushing 3 needs to be heat treated to more than 60 degrees to enhance wear resistance. On this basis, the surface of the jig body 1 is provided with size numerical identifications 9 corresponding to the through holes 2 one by one. Specifically, each positioning hole group corresponds to the position of a hole required to be drilled on a template 5 of a certain size, and the positions of these through holes 2 are adjusted according to the size of the template 5 actually used. Figure 1 As shown, in this embodiment, seven positioning hole groups are provided on the fixture body 1, corresponding to square templates 5 of sizes of 240mm, 300mm, 350mm, 400mm, 450mm, 500mm, 550mm, and 600mm, respectively. That is, size numerical marks 9 are engraved near the through holes 2 of the seven positioning hole groups on the fixture body 1, which are 240, 300, 350, 400, 450, 500, 550, and 600, respectively, to be suitable for templates 5 of different sizes, such as 240 size numerical mark 9 corresponding to the template 5 specification size of 240X240mm, and 300 size numerical mark 9 corresponding to the template 5 specification size of 300X300mm. The size numerical mark 9 is engraved on the surface of the fixture body 1 to prevent the operator from making mistakes in processing.

[0020] Furthermore, handles 6 are welded on both sides of the fixture body 1 to facilitate operators to flip and carry the fixture.

[0021] In actual application, taking a square plate of a template 5 with a size of 240X240mm as an example, it is necessary to process screw holes 7 with a spacing of 200X200mm on the square template 5 plate. In this embodiment, the spacing of the through holes 2 corresponding to the positioning hole group of this template 5 is 200mm. When the operator holds the handle 6 and places the jig body 1 on the template 5, the template 5 is automatically adsorbed and fitted with the positioning reference angle of the jig body 1 under the action of the magnet 4. At this time, one corner of the template 5 is aligned with the positioning reference angle of the jig body 1. At this time, it is only necessary to drill according to the hole position of the through hole 2 engraved with the 240 mark on the jig body 1, thereby obtaining a square template 5 plate with 4 screw holes 7.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
