Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary equipment for parts processing, and specifically relates to a double-sided integrated CNC machining tooling. Background Technology

[0002] In the aerospace field, small parts require multiple flipping and clamping operations during CNC machining due to their short cutting time. Therefore, clamping time constitutes a significant portion of the entire machining cycle. Simplifying clamping, accelerating clamping, and reducing operations are crucial for improving efficiency. Traditionally, typical small to medium-sized aerospace sheet metal parts require at least one clamping operation on each side to complete machining. Each side needs individual alignment, coordinate finding, and tool setting, resulting in lengthy clamping and preparation times. Since these typical small to medium-sized aerospace sheet metal parts constitute a large proportion of aerospace components, this significantly impacts the overall efficiency of machining companies. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a double-sided integrated CNC machining fixture that can complete the machining of both sides in one clamping and is applicable to different specifications of plates, which helps to improve work efficiency.

[0004] The objective of this utility model is achieved through the following technical solution: A double-sided integrated CNC machining fixture includes a base with supports at both ends. A rotating seat is provided on one side of the two supports opposite to the two rotating seats. A fixed plate and a movable plate are provided between the two rotating seats. The fixed plate and the movable plate are side-mounted and parallel to each other. The two ends of the fixed plate are fixedly connected to the two rotating seats respectively. The two ends of the movable plate are connected to the two rotating seats respectively. The movable plate can slide toward or away from the fixed plate. A positioning groove is provided on the side of the fixed plate opposite to the movable plate. The groove wall surface at one end of the positioning groove is a positioning reference surface. A positioning port opposite to the positioning groove is provided on the movable plate. Multiple positioning bolts for locking sheet metal parts are provided on the top of the fixed plate and the top of the movable plate.

[0005] Furthermore, the rotating seat is rotatably connected to the corresponding support via a rotating shaft. The rotating seat is provided with symmetrical limiting holes about the rotating shaft, and the support is provided with a limiting post that is inserted into the limiting hole. Furthermore, each of the two rotating plates has two parallel sliding grooves on its opposite side along the moving direction of the movable plate, and the end of the movable plate has a slider that is slidably connected to the sliding groove in a one-to-one correspondence.

[0006] Furthermore, the end of the movable plate is provided with connecting bolts, and the slider is mounted on the movable plate through the connecting bolts.

[0007] Furthermore, the positioning bolts on the fixed plate are evenly spaced along the length of the fixed plate and inserted into the positioning groove, and the positioning bolts on the movable plate are evenly spaced along the length of the movable plate and inserted into the positioning port.

[0008] Furthermore, the top of the support is equipped with a lifting lug.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model, through the arrangement of a base, support, rotating seat, fixed plate, movable plate, positioning groove, positioning port, and positioning bolts, places the two sides of the sheet metal part in the positioning groove and positioning port respectively, and makes the sheet metal fit against the positioning reference surface on the positioning groove, the bottom surface of the groove, and the lower side wall of the groove, with the positioning reference surface on the positioning groove as the reference. Then, the sheet metal part is locked and positioned by the positioning bolts. After positioning, the surface of the sheet metal part can be processed. During the processing, the processing surface of the sheet metal part can be changed by rotating the rotating seat, thereby realizing the completion of two-sided processing operations in one clamping and improving work efficiency.

[0010] 2. The positioning groove and positioning opening in this utility model can be used to place sheet metal parts of different lengths. At the same time, the positioning bolts and the distance between the movable plate and the fixed plate can be adjusted according to the thickness and width of the sheet metal parts, so that the tooling can be used to clamp and position sheet metal parts of different sizes and specifications, thereby improving the overall versatility of the tooling.

[0013] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0014] like Figures 1-2As shown, a double-sided integrated CNC machining fixture includes a base 1, with supports 2 fixed at both ends of the base 1. A rotating seat 3 is provided on one side opposite to the two supports 2. A fixed plate 4 and a movable plate 5 are provided between the two rotating seats 3. The fixed plate 4 and the movable plate 5 are arranged sideways and parallel to each other. The two ends of the fixed plate 4 are fixedly connected to the two rotating seats 3 respectively. The two ends of the movable plate 5 are connected to the two rotating seats 3 respectively. The movable plate 5 can slide towards or away from the fixed plate 4. A positioning groove 6 is provided on the side of the fixed plate 4 opposite to the movable plate 5. The groove wall surface at one end of the positioning groove 6 is a positioning reference surface 7. A positioning port 8 is provided on the movable plate 5 opposite to the positioning groove 6. Multiple positioning bolts 9 are provided on the top of the fixed plate 4 and the top of the movable plate 5 to lock the sheet metal parts.

[0015] Using the positioning reference surface 7, the bottom surface of the groove, and the lower side wall surface of the groove on the positioning groove 6 as the three positioning surfaces of the sheet metal part, when clamping the sheet metal part, place both sides of the sheet metal part in the positioning groove 6 and the positioning opening 8 respectively. Then, using the positioning reference surface 7 as a reference, make the sheet metal part fit with the three positioning surfaces, and then tighten the positioning bolt 9 so that the positioning bolt 9 is inserted into the positioning groove 6 and the positioning opening 8 and tightly abuts against the sheet metal, thereby locking and positioning the sheet metal part. After positioning, the surface of the sheet metal part can be machined. During the machining process, the machining surface of the sheet metal part can be changed by rotating the rotating seat 3, thus realizing the completion of two-sided machining operations in one clamping. Figure 1 As shown, a lifting lug 15 is fixed on the top of the support 2, which is used to lift the tooling as a whole onto the worktable of the CNC machine tool after the sheet metal parts are clamped and positioned.

[0016] The lengths of the positioning groove 6 and the positioning opening 8 can be set according to actual processing requirements to accommodate sheet metal parts of different lengths. For example... Figure 1 , 2 As shown, two parallel sliding grooves 12 are provided on the opposite side of the two rotating plates along the moving direction of the movable plate 5. The end of the movable plate 5 is provided with a slider 13 that is slidably connected to the sliding groove 12 in a one-to-one correspondence. The slider 13 is fixed to the movable plate 5 by the connecting bolt 14 on the movable plate 5. For sheet metal parts of different widths, the movable plate 5 can be moved closer to or further away from the fixed plate 4 according to the width of the sheet metal parts during clamping, thereby adjusting the distance between the movable plate 5 and the fixed plate 4 so as to place sheet metal parts of different widths.

[0017] The positioning bolts 9 on the fixed plate 4 are equally spaced along the length of the fixed plate 4, and the positioning bolts 9 on the movable plate 5 are equally spaced along the length of the movable plate 5. By adjusting the length of the positioning bolts 9 inserted into the positioning groove 6 and the positioning opening 8, parts of different thicknesses of sheet metal can be locked.

[0018] like Figure 1 , Figure 2As shown, a rotating shaft 10 is fixed on the rotating seat 3, allowing the rotating seat 3 to be rotatably connected to the corresponding support 2 via the rotating shaft 10. The rotating seat 3 has symmetrically arranged limiting holes about the rotating shaft 10, and a limiting post 11, which is inserted into the limiting hole, is movably inserted through the support 2. After the sheet metal part is clamped, the limiting post 11 can be removed to rotate the rotating seat 3, thereby adjusting the machining surface of the sheet metal part. After adjustment, the limiting post 11 is inserted into the limiting hole to lock the rotating seat 3. Since the positioning bolt 9 locks the sheet metal part onto the movable plate 5 and the fixed plate 4, effectively fixing the fixed plate 4 and the movable plate 5 together, the movable plate 5 will not slide freely during the rotation of the rotating seat 3.

[0019] Based on the above-mentioned double-sided integrated CNC machining fixture and its working principle, this utility model can be applied to clamping and positioning sheet metal parts of different sizes and specifications, improving the overall versatility of the fixture, and enabling two-sided machining operations to be completed in one clamping, thereby improving work efficiency.

[0020] Finally, although embodiments of the present invention have been shown and described above, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
