Description

Technical Field

[0001] This invention belongs to the field of transition plate drilling technology, specifically a transition plate drilling tool. Background Technology

[0002] In construction, machinery manufacturing, and steel structure engineering, square tubes are a common structural material. Drilling is often required at specific locations within their inner grooves to meet connection, installation, or other functional needs. Traditional processing methods typically rely on manual marking for positioning or the use of general-purpose fixtures for clamping before drilling. However, these methods have the following significant drawbacks: Low positioning accuracy: Manual marking is prone to deviation, making it difficult to guarantee the relative positional accuracy between the hole and the inner groove of the square tube, affecting assembly quality and performance; Unstable clamping: General-purpose fixtures often cannot effectively adapt to the special structure of the square tube's inner groove, easily shifting or loosening during clamping, leading to drilling position deviations and even workpiece scrap; Low efficiency: Each hole requires repositioning and clamping, making the operation cumbersome and time-consuming, difficult to meet the needs of mass production; Severe equipment wear: The lack of effective guidance and protection during drilling allows the drill bit to directly contact the tooling, causing rapid wear of the positioning holes and affecting the tooling's service life.

[0003] To overcome the above problems, some specialized drilling jigs have emerged in the existing technology, but their structures are complex, adjustments are inconvenient, or they are only applicable to square tubes of specific specifications, resulting in poor versatility. In addition, most jigs have failed to effectively solve the problem of simultaneously achieving reliable fixation in the inner groove and precise external positioning, and still have limitations such as inconvenient operation and insufficient adaptability.

Detailed Implementation

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0022] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0023] Example 1 Reference Figures 1-6 This embodiment provides a transition plate drilling fixture, including a positioning plate 100 and a clamping plate 200. The positioning plate 100 is provided with a positioning hole 101, and the clamping plate 200 is provided with a square groove 201, in which a fixing clamp 202 is provided.

[0024] In this embodiment, the relative positions of the positioning plate 100 and the clamping plate 200 are adjustable. When both are fully locked, the relative positions of the fixing clamp 202 for positioning and the positioning hole 101 for drilling are fixed. Therefore, by installing the fixing clamp 202 in the inner groove 301 of the square tube 300 and locking the positioning plate 100 and the clamping plate 200, a hole can be drilled at the positioning hole 101 to achieve the purpose of positioning and drilling at a specific relative position in the inner groove 301.

[0025] It should be noted that the thickness of the fixing clip 202 is greater than the depth of the square groove 201, so that after the fixing clip 202 is set in the square groove 201, a part of the fixing clip 202 protrudes outside the square groove 201.

[0026] A bushing 101a is provided in the positioning hole 101.

[0027] The bushing is made of wear-resistant material and is placed in the positioning hole 101 to prevent the positioning hole from being worn during drilling.

[0028] The positioning plate 100 has a stepped abutment plate 102 on its side, and a first threaded rod 103 is provided on the side of the abutment plate 102; a first screw sleeve 104 is provided on the first threaded rod 103, and a first screwing block 105 is provided on the first screw sleeve 104.

[0029] The first sleeve 104 is used to move on the first threaded rod 103 and abut against the clamping plate 200.

[0030] Furthermore, the fixing clip 202 includes a first triangular block 202a and a second triangular block 202b, and both the first triangular block 202a and the second triangular block 202b are provided with tapered grooves 202c.

[0031] Furthermore, the inclined surfaces, i.e. the opposing surfaces, of the first triangular block 202a and the second triangular block 202b can be set as magnetic attraction surfaces, so that the first triangular block 202a and the second triangular block 202b tend to move closer together.

[0032] The square groove 201 also has a through hole 203 in the middle, through which a second threaded rod 204 is inserted, and a cone 205 is provided at the end of the second threaded rod 204.

[0033] The frustum 205 is set in the conical groove 202c.

[0034] A second screw sleeve 206 is provided on the second threaded rod 204, and a second screwing block 207 is provided on the second screw sleeve 206.

[0035] During the rotation of the second sleeve 206 relative to the second threaded rod 204, the second threaded rod 204 will be pulled down as the end of the second sleeve 206 abuts against the bottom side of the clamping plate 200. During the pull-down process, the cone 205 squeezes the cone groove 202c to squeeze and separate the first triangular block 202a and the second triangular block 202b.

[0036] An end block 208 is provided at the end of the clamping plate 200, and a placement groove 208a is provided on the end block 208.

[0037] A side plate 209 is fixed to the side of the end block 208, and a vertical groove 209a is provided on the side plate 209.

[0038] It also includes a square tube 300, the inner wall of which is provided with an inner groove 301, and a fixing clip 202 is disposed in the inner groove 301.

[0039] In use, first place the fixing clamp 202 in the inner groove 301, and screw the second screwing block 207 to pull down the second threaded rod 204 to open the fixing clamp 202 and fix it in the inner groove 301. Then, attach the positioning plate 100 to the outer side of the square tube 300, set the first threaded rod 103 in the vertical groove 209a, and screw the second screw sleeve 206 to make the stepped abutment plate 102 abut against one side of the side plate 209 and the second screw sleeve 206 abut against the other side of the side plate 209. Fix the positioning plate 100, clamping plate 200, and square tube 300 together. The position of the positioning hole 101 is the position that needs to be drilled in advance. Drilling is done using a drilling device.

[0040] It should be noted that the top surface of the rear end block 208 in the inner groove 301 of the fixing clip 202 does not exceed the outer side of the square tube 300, so as to avoid the positioning plate 100 being unable to fit with the outer side of the square tube 300; the top surface of the side plate 209 exceeds the outer side of the square tube 300, so that the second screw sleeve 206 can abut against the outer side of the side plate 209.

[0041] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
