Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, in particular to a detachable device. Background Art

[0002] At present, some products have high requirements for the hole-making position and relative position in space, and need to use drilling tools to make holes.

[0023] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. 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.

[0024] At present, in the production and processing of a certain type of product, large-scale tooling equipment is often used to ensure that the product meets the requirements of the drawings. The accuracy of large-scale tooling equipment will directly affect the accuracy of product processing. Some products have high requirements for the hole making position and spatial relative position, and need to use drilling tools to punch holes. Specifically, the bottom position of the drilling tool needs to be installed with a positioning drill template to punch holes in the product. The external contour size of the traditional drilling tool is 1900mm×380mm×775mm, and there are about 80 welded parts. It belongs to a type of tooling with a complex structure. The bottom position of the drilling tool is completed by welding and assembly, and the welding amount is large. During welding, the bottom position of the drilling tool is severely deformed, which causes the entire tooling to be scrapped; and the welding stress will be released during the placement of the tooling, which will cause the shape and position tolerance of the bottom position of the tooling to not meet the requirements, that is, affect the flatness requirements of the tooling.

[0025] Therefore, in order to solve the above problems and ensure the reliability of the product, the bottom position of the drilling tool is partially split, that is, split into a base plate 1 and a drilling jig hole seat flange 2. Figure 1 is a top view of a detachable device provided by an embodiment of the present invention; Figure 2 is a front view of a detachable device provided by an embodiment of the present invention; Figure 1 and Figure 2 As shown, the device comprises:

[0026] A bottom plate 1, one side of the bottom plate 1 is a connection side, and the other side is a free side; a drilling jig hole seat flange 2 is detachably connected to the connection side.

[0027] Specifically, the base plate 1 and the drilling jig hole seat flange 2 are both made of aluminum. The base plate 1 is an integrated structure. The drilling jig hole seat flange 2 is a circular ring structure.

[0028] Figure 3 is a top view of a drilling jig hole seat flange 2 provided in an embodiment of the present invention; Figure 4 2 is a front view of the jig hole seat flange 2 provided in an embodiment of the present invention; Figure 3 and Figure 4 As shown, the jig hole seat flange 2 is provided with a first jig hole seat 3 and a second jig hole seat 4.

[0029] There are multiple first jig hole seats 3 and second jig hole seats 4. Specifically, in the present invention, the diameter of the first jig hole seat 3 is smaller than the diameter of the second jig hole seat 4, four first jig hole seats 3 are provided, and four second jig hole seats 4 are also provided, that is, one first jig hole seat 3 and one second jig hole seat 4 are a pair, and there are 4 pairs in total, and the first jig hole seat 3 and the second jig hole seat 4 are adjacent in each pair, and the central axes of the first jig hole seat 3 and the second jig hole seat 4 in each pair are on the same line.

[0030] In the prior art, parts need to be welded at the bottom of the drilling tool, that is, oblique ribs will be welded across the entire base plate 1 in the length direction of the bottom of the drilling tool, supporting vertical plates will be welded on the connecting side in the width direction, and auxiliary reinforcing ribs will be welded on the remaining parts. Welding parts will bring the risk of stress deformation.

[0031] In order to solve the above problems, the bottom position of the drilling tool is divided into a bottom plate 1 and a drilling jig hole seat flange 2. Specifically, in the present invention, a through threaded hole is provided on the connection side of the bottom plate 1, and the drilling jig hole seat flange 2 is threadedly connected with the threaded hole. That is, the bottom of the drilling jig hole seat flange 2 is made of external threads, and the bottom plate 1 is processed with internal threads matching the drilling jig hole seat flange 2, and the two are fixedly connected by threaded connection.

[0032] When the jig hole seat flange 2 is screwed and assembled, after the jig hole seat flange 2 is rotated to the specified position, the edge of the jig hole seat flange 2 needs to be fixedly connected to the connection side to ensure that the jig hole seat flange 2 does not rotate. In an optional embodiment, the edge of the jig hole seat flange 2 is welded to the connection side. In another optional embodiment, the edge of the jig hole seat flange 2 is fixedly connected to the connection side by a screw and a nut. In a third optional embodiment, the edge of the jig hole seat flange 2 can be fixedly connected to the connection side by a fixing clamp. It should be noted that the present invention does not limit the fixed connection method of the edge of the jig hole seat flange 2 and the connection side.

[0033] In an optional embodiment, the bottom surface of the connection side is not coplanar with the bottom surface of the free side.

[0034] Beneficial effects of the present invention:

[0035] The present invention provides a detachable device, which includes: a bottom plate 1, one side of the bottom plate 1 is a connection side, and the other side is a free side; a drilling jig hole seat flange 2 is detachably connected to the connection side. By splitting the bottom position of the drilling jig, that is, splitting it into the bottom plate 1 and the drilling jig hole seat flange 2, when deformation occurs locally, for example, when the drilling jig hole seat flange 2 is deformed, it can be disassembled and replaced, and the entire jig will not be scrapped, thereby indirectly saving manpower and material costs, and the production task of the product will not be delayed due to the repair or reprocessing of the jig, and the flatness requirement of the jig is guaranteed.

[0036] 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. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
