Technical Field
[0001] This utility model relates to a drilling fixture, and more particularly to a universal drilling fixture for workpieces of various specifications. Background Technology
[0002] A multi-size universal drilling fixture is a fixture designed to accommodate drilling operations on workpieces of different sizes and shapes. Through its flexible design, this fixture allows for the fixing and machining of workpieces of various sizes without replacing the entire fixture, thereby improving production efficiency and reducing costs.
[0003] To resist the vibrations and cutting forces generated during drilling, the fixture needs sufficient rigidity and stability to prevent workpiece displacement or deformation, thereby ensuring machining quality. When fixing workpieces of different specifications, the rigidity and stability of the drilling fixture inevitably decrease. Utility Model Content
[0004] The purpose of this utility model is to provide a universal drilling fixture for workpieces of various specifications to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a universal drilling fixture for multi-specification workpieces, comprising a mounting plate, a limiting groove, a fixing plate, a threaded adjustment structure, a clamping plate, a transmission column, a storage groove, a sliding groove, and a side-end stabilizing structure. The mounting plate has a limiting groove in the middle, the fixing plate is slidably connected to the rear of the limiting groove, the threaded adjustment structure is installed on the fixing plate through the rear end of the limiting groove, the clamping plate is slidably connected to the front of the limiting groove, the transmission column is installed on the front end of the clamping plate, the storage grooves are respectively opened in the middle of the left and right ends of the limiting groove, the sliding groove is opened through the left and right ends of the mounting plate into the storage groove, and the side-end stabilizing structure is installed in the limiting groove through the storage groove.
[0006] Based on the above technical solution, the side-end stabilizing structure includes a right-angle support plate, a rotating shaft support column, a bracket, and rollers. A rotating shaft is installed at the external corner of the right-angle support plate, and the right-angle support plate corresponds to the storage groove. The support plate is hinged to the right-angle support plate through the rotating shaft, and the support plate is slidably connected to the sliding groove. The brackets are respectively installed on the upper and lower parts of the inner end of the right-angle support plate, and the rollers are respectively installed on the upper and lower parts of the right-angle support plate through the brackets.
[0007] Based on the above technical solution, the right-angle support plate moves in the limiting groove or the storage groove through the support column.
[0008] Compared with the prior art, the present invention has the following advantages: The present invention incorporates a side-end stabilizing structure on the side end of the rotating hole fixture, which provides fitting support for workpieces of different specifications with different side-end shapes, thereby enhancing the rigidity and stability of the rotating hole fixture.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0014] like Figures 1 to 3 As shown, a universal drilling fixture for multi-specification workpieces includes a mounting plate 1, a limiting groove 2, a fixing plate 3, a threaded adjustment structure 4, a clamping plate 5, a transmission column 6, a storage groove 7, a sliding groove 8, and a side-end stabilizing structure 9. The mounting plate 1 has a limiting groove 2 in the middle. The fixing plate 3 is slidably connected to the rear of the limiting groove 2. The threaded adjustment structure 4 is installed on the fixing plate 3 through the rear end of the limiting groove 2. The clamping plate 5 is slidably connected to the front of the limiting groove 2. The transmission column 6 is installed on the front end of the clamping plate 5. The storage groove 7 is opened in the middle of the left and right ends of the limiting groove 2. The sliding groove 8 is opened in the storage groove 7 through the left and right ends of the mounting plate 1. The side-end stabilizing structure 9 is installed on the limiting groove 2 through the storage groove 7.
[0015] The side-end stabilizing structure 9 includes a right-angle support plate 10, a rotating shaft 11, a support column 12, a bracket 13, and rollers 14. The rotating shaft 11 is installed at the external corner of the right-angle support plate 10, and the right-angle support plate 10 corresponds to the storage groove 7. The support plate 12 is hinged to the right-angle support plate 10 through the rotating shaft 11, and the support plate 12 is slidably connected to the sliding groove 8. The bracket 13 is installed on the upper and lower parts of the inner end of the right-angle support plate 10, and the rollers 14 are installed on the upper and lower parts of the right-angle support plate 10 through the bracket 13.
[0016] The right-angle support plate 10 is movable in the limiting groove 2 or the storage groove 7 via the support column 12.
[0017] The working principle of this utility model is as follows: Workpieces of different specifications are placed between the fixing plate 3 and the clamping plate 5 within the limiting groove 2. The clamping plate 5 is pushed by the transmission column 6, clamping the workpiece in conjunction with the fixing plate 3. After clamping, the right-angle support plate 10 is pushed inward along the sliding groove 8 by the left and right support columns 12. The right-angle support plate 10 extends out of the receiving groove 7 and contacts the side end of the workpiece within the limiting groove 2. With the cooperation of the rotating shaft 11 and the rollers 14, the upper and lower rollers contact the regular or irregular side end of the workpiece together, forming a fixed support under the support of the right-angle support plate 10, achieving four-point stability for the left and right ends of the workpiece. This enhances the rigidity and stability of the drilling fixture.
[0018] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
