Description

Technical Field

[0001] This utility model relates to a laser processing fixture for irregularly shaped sheet metal parts, belonging to the technical field of auxiliary operation or equipment for laser beam processing in machine tools (B23K26 / 70). Background Technology

[0002] To meet the demands of various special operating environments, sheet metal parts are evolving towards more complex shapes and more precise dimensions. Laser processing is currently the mainstream method for sheet metal processing. It utilizes the thermal effect generated by a laser beam focused on the surface of the part to melt the cut, ultimately completing the blanking and separation. Furthermore, it can collaborate with multi-axis robotic arms to easily achieve the cutting of various complex contours.

[0003] However, in traditional laser processing, sheet metal parts often rely on local clamping for fixation, which not only easily causes the positioning reference to shift and makes it difficult to achieve stable workpiece positioning, but also causes the weak areas of the workpiece to bend due to clamping force or laser thermal stress, further amplifying processing errors and, in severe cases, directly leading to the scrapping of the workpiece. Utility Model Content

[0004] The technical problem to be solved by this utility model is: how to achieve stable positioning of sheet metal parts during laser processing.

[0005] The technical solution proposed by this utility model to solve the above-mentioned technical problems is as follows: a laser processing fixture for irregularly shaped sheet metal parts, including a strip-shaped base plate, a top plate, and a strip-shaped contour block; multiple vertical, upward-facing concave fixing plates are fixed at intervals along the length direction on the top surface of the base plate, and pads are fixed on the top surface of the base plate between adjacent fixing plates, the height of the pads being level with the lowest point of the concave surface of the fixing plate; two spaced extension plates are fixed on the top surfaces of both ends of the base plate, and vertical support plates are fixed on the top surface of the end of the extension plates extending beyond the edge of the base plate, the top surfaces of the support plates being fixed to the bottom surface of the top plate, and multiple bolts are screwed onto the top plate at intervals along the length direction; a sheet metal part is fitted over the contour block and placed inside the concave surface of the fixing plate; as the bolts are pressed down, the surface of the sheet metal part is tightly attached to the concave surface of the fixing plate and the top surface of the pads.

[0006] Furthermore, the bottom surface of the contour block is provided with multiple weight-reduction grooves.

[0007] Furthermore, the top surface of the contour block is provided with an annular groove.

[0008] Furthermore, the two ends of the contour block are fixed with lifting rings.

[0009] The beneficial effects of this utility model are as follows: Since the sheet metal part is fitted outside the contour piece and placed in the concave surface of the fixing plate, and the sheet metal part and the contour piece are tightly fixed in the concave surface of the fixing plate by tightening the bolts on the top plate, and the pads between the fixing plates also support the sheet metal part, it can prevent the sheet metal part from deflecting due to excessive pressure in some parts, thus preventing the cutting dimensions from deviating, and achieving stable positioning of the sheet metal part.

[0016] Example

[0017] This embodiment provides a laser processing fixture for irregularly shaped sheet metal parts, such as... Figure 1 , 2 As shown in Figure 3, the device includes a strip-shaped base plate 1, a top plate 2, and a strip-shaped contour block 3. Multiple vertical, upward-facing concave fixing plates 4 are fixed at intervals along the length of the top surface of the base plate 1. Pads 5 are fixed to the top surfaces of adjacent fixing plates 4, with the height of the pads 5 being level with the lowest point of the concave surface of the fixing plate 4. Two spaced extension plates 6 are fixed to the top surfaces of both ends of the base plate 1. Vertical support plates 7 are fixed to the top surfaces of the ends of the extension plates 6 extending beyond the edge of the base plate 1. The top surfaces of the support plates 7 are fixed to the bottom surface of the top plate 2. Multiple bolts 8 are screwed onto the top plate 2 at intervals along its length. The surface curvature of the strip-shaped contour block 3 is adapted to the internal shape of the irregular sheet metal part. The contour block 3 is fitted with a sheet metal part and placed within the concave surface of the fixing plate 4. As the bolts 8 are pressed down, the surface of the sheet metal part adheres tightly to the concave surface of the fixing plate 4 and the top surface of the pads 5.

[0018] like Figure 1 ,3 As shown in Figure 4, the bottom surface of the contour block 3 is provided with multiple weight-reducing grooves 12, and threaded holes 9 are opened at both ends to install lifting rings 10 for easy repeated disassembly and transportation; at the same time, the top surface of the contour block 3 is provided with an annular groove 11 that fits against the inner wall of the sheet metal part to improve stability.

[0019] This utility model is not limited to the above embodiments. All technical solutions formed by equivalent substitutions fall within the protection scope claimed by this utility model.
