The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0037] like Figures 1-3 As shown, this embodiment provides a machined product fixing fixture. Specifically, the machined product fixing fixture includes a product support assembly 100 and a cover 200.
[0038] like Figure 2 As shown, the product support assembly 100 is provided with a contoured support portion 111 and a processing area. The product to be processed 300 can be set on the contoured support portion 111 in a conformal manner, and the surface of the contoured support portion 111 is provided with a plurality of adsorption pores 112. The adsorption pores 112 can adsorb the product to be processed 300. The conformal setting specifically means that the surface shape of the contoured support portion 111 matches the surface shape of the product to be processed 300, so that the product to be processed 300 and the contoured support portion 111 fit together closely, and there is no obvious gap or misalignment between the two at any part, thereby providing stable, uniform and tight support for the product to be processed 300.
[0039] The surface shape of the contour support 111 is determined according to the outer shape of the product 300 to be processed, such as... Figure 2 As shown, when the product to be processed 300 is a HUD product with a curved surface structure, the surface of the contour support 111 presents a matching curved shape.
[0040] like Figure 1and Figure 2 As shown, the cover 200 is movably disposed on the product support assembly 100, and the cover 200 can cover the product 300 to be processed on the contour support 111. Specifically, the cover 200 can be moved to a state that covers and protects the product 300 to be processed, preventing debris, dust and other contaminants generated during processing from damaging the fixed part 301 of the product 300 to be processed, or it can be moved to a position away from the contour support 111, so as to facilitate the installation or removal of the product 300 to be processed from the contour support 111.
[0041] In use, firstly, the fixed portion 301 of the product to be processed 300 is shaped and placed on the contour support 111, with the processed portion 302 of the product to be processed 300 located in the processing area. Since the shape of the contour support 111 matches the fixed portion 301 of the product to be processed 300, a good fit is achieved. Next, the suction vent 112 draws air, causing the fixed portion 301 of the product to be processed 300 to be adsorbed onto the contour support 111, achieving a stable fixation. Then, the movable cover 200 covers the fixed portion 301 of the product to be processed 300 on the contour support 111, protecting it from external contamination and damage during subsequent processing. After the processed portion 302 of the product to be processed 300 has been processed in the processing area, the suction vent 112 releases the adsorption, the cover 200 is removed, and the product to be processed 300 can be removed.
[0042] The machining product fixing fixture provided in this embodiment features a contoured support 111 that can conformally mount the product 300 to be processed, adapting to irregularly shaped products 300. This increases the contact area and fit between the fixture and the product, improving the stability of the fixation. The adsorption vents 112 utilize negative pressure to adsorb and fix the product 300, avoiding damage caused by pressure or adhesive residue in traditional fixing methods, effectively protecting the product's precision and appearance quality. The cover 200 further protects the adsorbed and fixed portion 301 of the product 300, preventing it from being contaminated with processing debris. In summary, this stable and non-destructive fixing method reduces product damage caused by fixing, thereby significantly improving the yield of the product 300. It also reduces production interruptions and adjustments caused by product fixing problems, thus improving production efficiency.
[0043] In some embodiments, a vacuum pump is provided that engages with the adsorption vents 112 of the fixture for fixing the machined product. Specifically, the vacuum pump is connected to each adsorption vent 112, and the vacuum pump controls the airflow through each adsorption vent 112 to allow the contour support 111 to adsorb the product 300 to be processed. Optionally, the vacuum pump is a vacuum generator, which is connected to the adsorption vents 112 via a flexible hose to adjust the vacuum adsorption state of the contour support 111.
[0044] In some embodiments, the surface of the contour support 111 has a plurality of adsorption pores 112. The plurality of adsorption pores 112 can disperse adsorption stress, reduce stress concentration on the product surface, and avoid stress concentration that could damage the product.
[0045] like Figure 2 and Figure 3 As shown, optionally, the product support assembly 100 is provided with a groove 121, and the projection of the processing area in the height direction is located within the groove 121. During the processing of the processing portion 302 of the product 300, the waste generated can fall and be collected in the groove 121, preventing waste from scattering everywhere, helping to maintain a clean working environment and reducing the difficulty of cleaning. Moreover, the groove 121 can also prevent waste from damaging or interfering with other parts of the product support assembly 100 and surrounding equipment, extending the service life of the tooling.
[0046] like Figure 3 As shown, optionally, the product support assembly 100 includes a contour support base 110 and a chip conveyor base 120. The contour support base 110 is provided with a contour support portion 111 and an opening 113. The area inside the opening 113 serves as the processing area. The chip conveyor base 120 is provided with a groove 121. The contour support base 110 is detachably mounted on the chip conveyor base 120. By replacing different contour support bases 110, the tooling can be quickly adjusted to meet the processing requirements of different models or shapes of products 300 to be processed, improving the versatility and flexibility of the tooling. This allows the chip conveyor base 120 to be used for various types of products 300 to be processed, requiring only the replacement of the contour support base 110, thus reducing costs. The groove 121 on the chip conveyor base 120 is specifically for chip removal, clearly distinguishing its function from the opening 113 of the contour support base 110, reducing the impact of chips generated during processing on the quality of the product 300 to be processed.
[0047] In some embodiments, the product support assembly 100 is fixed on the table of the machine tool, thereby keeping the product 300 to be processed in a position on the machine tool, so that the machine tool can perform processing operations on the product 300 on the product support assembly 100.
[0048] Optionally, the chip conveyor 120 has multiple fixed steps 123 along its edge. By placing the chip conveyor 120 on the table of a machine tool and applying pressure to the corresponding fixed steps 123 using clamping members, the chip conveyor 120 can be fixed. Multiple fixed steps 123 provide multiple fixing points, making the chip conveyor 120 more securely fixed on the machine tool table, reducing shaking and displacement during machining, and ensuring machining accuracy. The fixed steps 123 provide a limiting function for the clamping members, ensuring consistent positioning each time and guaranteeing machining accuracy. For example, the clamping member can be a pressure plate.
[0049] In some embodiments, the chip removal seat 120 is rectangular, with four fixed steps 123 located at the four corners of the chip removal seat 120. The fixed steps 123 at the four corners are evenly distributed, making the clamping force on the chip removal seat 120 more balanced and further enhancing the fixing effect.
[0050] like Figures 1-3 As shown, optionally, the machining product fixing fixture also includes a chip extraction component. The product support assembly 100 is provided with a guide channel 122, and the chip extraction component communicates with the groove 121 through the guide channel 122. The chip extraction component, communicating with the groove 121 through the guide channel 122, can actively and quickly suck out the chips from the groove 121, improving chip removal efficiency and reducing contamination and damage to the product 300 caused by chip residue. Furthermore, rapid chip removal can reduce production interruptions caused by chip cleaning, improving production efficiency and continuity. In some embodiments, the guide channel 122 is disposed on the chip removal seat 120. The chip extraction component can be an industrial vacuum cleaner, which communicates with the guide channel 122 through a suction pipe.
[0051] like Figure 2 and Figure 3 As shown, optionally, the guide channel 122 extends horizontally through the groove 121, and both ends of the guide channel 122 are connected to the chip-collecting component. Connecting both ends to the chip-collecting component helps balance the suction force, ensuring that chips at all locations within the groove 121 receive uniform suction force, preventing localized chip residue. The guide channel 122 extending horizontally through the groove 121 and being connected to the chip-collecting component at both ends increases the effective area and suction range of the chip-collecting process, enabling more comprehensive and rapid extraction of chips from the groove 121, significantly improving the chip-collecting effect.
[0052] like Figure 2 As shown, optionally, the product support assembly 100 is provided with a receiving groove 114, and the contour support part 111 is disposed on the bottom wall of the receiving groove 114. The cover member 200 can cover the receiving groove 114. The receiving groove 114 provides a protective space for the product 300 to be processed. When the cover member 200 covers the receiving groove 114, it can more effectively prevent external debris and splashes during processing from entering, thus providing better protection for the product 300 to be processed. The receiving groove 114 makes reasonable use of the space of the product support assembly 100, making the entire tooling structure more compact. The receiving groove 114 helps to quickly and accurately place the product 300 to be processed in the correct position, improving installation efficiency and accuracy. In some embodiments, the receiving groove 114 is disposed on the contour support base 110.
[0053] like Figure 2As shown, optionally, the cover 200 can abut against the product support assembly 100 surrounding the contour support portion 111. The cover 200 is provided with a relief groove 201, which is used to avoid the product 300 to be processed on the contour support portion 111. The cover 200 can abut against the product support assembly 100 surrounding the contour support portion 111, making the cover 200 more stable during operation and improving the sealing performance of the cover, thus better preventing external debris and processing debris from entering. The relief groove 201 ensures that the cover 200 will not collide or interfere with the product 300 to be processed when covering, avoiding damage to the product 300 to be processed.
[0054] In some embodiments, the surface of the product to be processed 300 covered by the cover member 200 is curved, and the groove wall of the avoidance groove 201 can be adaptively designed as a curved shape to avoid obstacles, thereby improving compactness.
[0055] like Figure 2 As shown, optionally, the contouring support 111 and the processing area are arranged adjacent to each other in the horizontal direction, and one end of the cover 200 is rotatably disposed on the side of the contouring support 111 away from the processing area. This arrangement results in a compact horizontal layout of the contouring support 111, the processing area, and the cover 200, saving space. The rotatable arrangement of one end of the cover 200 makes opening and closing the cover 200 more convenient and faster, improving work efficiency. The position of the cover 200 effectively prevents debris and foreign objects that may be generated during processing from entering the contouring support 111, while simultaneously preventing interference with the processing area. In some embodiments, the cover 200 is a cover plate, one end of which is rotatably disposed on the chip extraction seat via a pivot, and the cover plate can rotate around the pivot to cover the contouring support 110.
[0056] like Figure 2 As shown, optionally, multiple contouring support portions 111 and one-to-one corresponding cover members 200 are provided, with each cover member 200 capable of covering the product 300 to be processed on the corresponding contouring support portion 111. The provision of multiple contouring support portions 111 can further form more adsorption and fixation, thereby further improving the fixation effect. The provision of multiple cover members 200 can protect each fixed part 301 of the product 300 to be processed, thereby further protecting the precision and appearance of the product 300 to be processed.
[0057] like Figure 2 As shown, in this embodiment, two contour support parts 111 are provided, located on both sides of the processing area. The two contour support parts 111 can provide more balanced support for the product 300 to be processed, reducing product deformation or displacement caused by uneven force during processing, making the product more stable during processing, and helping to ensure processing accuracy and quality.
[0058] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
