Description

Technical Field

[0001] This utility model relates to the field of machining tooling technology, and in particular to a fan-shaped machining tooling structure. Background Technology

[0002] Positioning fixtures are specialized tools used in industrial manufacturing to fix, position, and support workpieces, aiming to ensure the accuracy, efficiency, and operational safety of machining or assembly. Their core structure includes components such as clamps, positioning pins, positioning plates, stops, and pressure plates. Some complex fixtures also integrate a connecting body with multiple positioning units to adapt to specific process requirements. Positioning fixtures have a wide range of applications, covering automotive manufacturing (such as welding body panels), machining (fixing workpieces in CNC machining centers), aerospace (assembly of complex components), nuclear power equipment installation (anchor bolt positioning), and the electronics industry (circuit board welding). By using precise positioning references, the displacement and deformation of workpieces during machining can be effectively controlled. Common positioning fixtures include vises; however, for positioning workpieces requiring machining at a certain angle, vises have complex positioning methods and low accuracy.

[0003] Chinese patent CN201620976652.3 discloses a processing device for quickly changing jaws, including a main body mounted on a vise. One end of the main body has a female jaw, which is connected to a female jaw via a slot and a locking block. The main body and the female jaw are each connected to the female jaw via pressure plates. A jaw cavity is formed on the female jaw. This design requires improvement.

[0004] This invention overcomes the shortcomings of the prior art and provides a fan-shaped machining fixture structure that can position and fix the workpiece to be processed at a certain angle. Utility Model Content

[0022] like Figure 1-2 The diagram shown is a schematic representation of an embodiment of the fan-shaped machining fixture structure provided by this utility model.

[0023] Please refer to Figure 1-2 This embodiment is used for fixing a workpiece at a certain angle, and maintaining this angle during processing. The embodiment includes a fixture 100, which has multiple vertical surfaces 110 and multiple concave fixing surfaces 120 connected together. Both the vertical surfaces 110 and the fixing surfaces 120 are smooth planes. Adjacent fixing surfaces 120 are set at a first predetermined angle 121, the boundary line 130 between adjacent fixing surfaces 120 is a straight line, and the fixing surface 120 is set at a second predetermined angle 122 with the vertical surface 110. The lengths of the fixing surfaces 120, the boundary line 130, and the vertical surface 110 are equal. The fixing surfaces 120 are used to mount the workpiece to be processed, allowing the workpiece to be processed at the first predetermined angle 121.

[0024] The size of the first predetermined included angle 121 can be matched and set according to the angle processing parameters of the workpiece to be processed. The workpiece is rigidly set at the first predetermined angle, and the angle of the workpiece is fixed during processing, and will not shift due to external forces during processing. The first predetermined angle 121 of the fixed surface 120 is obtained by processing itself, and the angle is constant, so no additional manual adjustment is required, and there is no problem with adjustment accuracy.

[0025] In one embodiment, the fixing surface 120 includes a first fixing surface 123 and a second fixing surface 124. The first fixing surface 123 and the second fixing surface 124 are set at a first predetermined angle 121. The size of the first predetermined angle 121 is twice the size of the second predetermined angle 122, that is, the horizontal plane where the boundary line 130 is located is parallel to the horizontally set vertical plane 110.

[0026] Furthermore, the widths of the first fixing surface 123 and the second fixing surface 124 are equal, and the lengths of the first fixing surface 123 and the second fixing surface 124 are equal, as are the lengths of the vertical surface 110 and the boundary line 130. That is, the first fixing surface 123 and the second fixing surface 124 are symmetrically arranged with the boundary line 130 as the center line. This symmetrical structure facilitates the fixing of the tooling body 100 itself in machining equipment such as milling machines.

[0027] Specifically, the tooling body 100 has a cubic structure with six faces in pairs. In this embodiment, a cube structure is adopted, in which a pair of opposite surfaces are concave to form a first fixing surface 123 and a second fixing surface 124. The remaining four faces are vertical surfaces 110, and adjacent vertical surfaces 110 are perpendicular to each other. The vertical surfaces 110 on the top and bottom sides are squares, and the vertical surfaces 100 on the front and back sides are polygons with concave sides. The left and right sides are the fixing surfaces 120. The first fixing surface 123 forms a second predetermined angle 122 with the upper vertical surface 110, and the second fixing surface 124 forms a second predetermined angle 122 with the lower vertical surface 110. The first fixing surface 123 and the second fixing surface 124 are perpendicular to the front and back vertical surfaces 110, respectively.

[0028] The distance from the upper vertical surface 110 to the boundary line 130 is 30-40mm, preferably 35mm in this embodiment, meaning the side length of the aforementioned cube structure is 70mm. The first predetermined included angle 121 is 33-40 degrees, 144 degrees in the illustration, and the second predetermined included angle 122 is 72 degrees. The length of the fixing surface 110 is 65-75mm, and the width of the fixing surface 110 is 65-75mm, preferably 70mm in this embodiment.

[0029] In one embodiment, the fixing surface 120 is provided with a threaded hole 140, which is perpendicular to the fixing surface 120. The threaded hole 140 is used to install screws, and the workpiece to be processed is fixedly connected to the fixing surface 120 through screws and threaded hole 140.

[0030] Furthermore, there are multiple threaded holes 140, and the spacing between adjacent threaded holes 140 may be equal or unequal. In the figure, the threaded holes 140 provided on the first fixing surface 123 are spaced unequally, and there are 3 of them; the threaded holes 140 provided on the second fixing surface 124 are spaced equally, and there are 3 of them. The depth of the threaded holes 140 can penetrate the vertical surface on the upper or lower side.

[0031] Specifically, the distance between the axis of the threaded hole 140 and the vertical plane 110 on the upper or lower side is 7-8 mm. In this embodiment, 7.4 mm is preferred.

[0032] In summary, the embodiments provided by this utility model have multiple fixed surfaces at certain angles in the tooling body for mounting and fixing the workpiece to be processed, so that the workpiece is rigidly set at a certain angle. The angle of the workpiece is fixed during processing and will not shift due to the external force of processing. Moreover, compared with the positioning and fixing method of the vise, the installation angle of the fixed surface in this solution remains unchanged, and no additional manual adjustment is required. Therefore, there is no problem of adjustment accuracy. The finished product obtained by positioning and processing the workpiece through the tooling structure of this solution has higher accuracy.

[0033] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
