Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a multi-purpose calibration fixture. Background Technology

[0002] Alignment fixtures are widely used in industrial production, especially in processes involving riveting and welding, where it is often necessary to correct deformed parts resulting from machining or welding. Currently, many alignment fixtures suffer from problems such as complex design, difficult assembly, limited service life, and poor adaptability. These fixtures are typically designed for workpieces of specific specifications, making them difficult to use flexibly with workpieces of different shapes and sizes. This necessitates preparing multiple dedicated fixtures for different workpieces, increasing production costs. Furthermore, the assembly and disassembly processes of existing fixtures are time-consuming, hindering production efficiency, and they provide insufficient protection for the workpiece surface, making them susceptible to further damage during the alignment process.

[0003] In the existing technology, the initial tooling for the stator frame of the flotation machine is only temporarily made according to the size and specifications of a single product. It requires multiple processes such as drawing, assembling, and welding. After changing the product specifications, it is necessary to go through gas cutting, grinding and other steps again, which increases the consumption of materials and is cumbersome. During the post-weld correction process, due to its complex shape and diverse specifications, the existing tooling is difficult to meet the requirements of multi-specification adaptability and correction accuracy.

[0004] Therefore, existing technologies have shortcomings and need to be improved and developed. Summary of the Invention

[0026] In the existing technology, the initial tooling of the stator frame of the flotation machine is only temporarily made according to the size and specifications of a single product. It requires multiple processes such as drawing, assembling and welding. After changing the product specifications, it is necessary to go through gas cutting, grinding and other steps again, which increases the consumption of materials and is cumbersome. In the post-weld correction process, due to its complex shape and diverse specifications, the existing tooling has the problem of being unable to meet the requirements of multi-specification adaptability and correction accuracy.

[0027] Therefore, this utility model embodiment provides a multi-purpose calibration fixture, referring to... Figure 1 It includes a base plate 1, on which several connecting blocks 2 are detachably connected; it also includes several support blocks 4, which are detachably connected to the connecting blocks 2. One end of the support block 4 has a recessed groove, and the other end of the support block 4 is a flat surface. The groove is adapted to the outer contour of the connecting block 2. When the deformable part is placed on the end face of the support block 4 for correction, a pressing block 5 is placed on the side of the deformable part facing away from the support block 4 to bear the correction pressure.

[0028] The deformable component is the stator frame of a flotation machine in mining equipment. Various specifications are available, including KYF50, KYF100, KYF130, KYF160, KYF200, and KYF300, and it is used for initial welding deformation correction. The correction pressure comes from external mechanical force pressing the pressing block 5 to achieve the correction effect. This utility model embodiment provides a multi-purpose correction fixture, see reference... Figure 1 It mainly consists of a base plate 1, several detachable connecting blocks 2, and support blocks 4. Figure 1 A stator frame is also placed inside to indicate the installation status. One end of the support block 4 is designed as a concave groove to fit the outer contour of the connecting block 2 for a stable connection; the other end is a flat surface to support the deformed part being corrected. Simultaneously, a pressing block 5 is provided on the other side of the deformed part to bear the correction pressure, ensuring uniform force transmission during the correction process. The modular design of the base plate 1, connecting block 2, and support block 4 makes the fixture highly versatile for correcting deformed parts of different specifications and shapes, and easy to assemble and disassemble; the fit between the groove and the outer contour of the connecting block 2 enhances the stability of the support structure; and the pressing block 5 ensures uniform force distribution on the deformed part during correction, avoiding secondary deformation during the correction process.

[0029] In some embodiments, the end of the connecting block 2 facing the base plate 1 has a protruding tenon, and the surface of the base plate 1 facing the connecting block 2 has a mortise adapted to the tenon, the length of the tenon being less than the thickness of the base plate 1.

[0030] The tenon and mortise structure improves the connection strength between the connecting block 2 and the base plate 1, and the tenon design, which is shorter than the thickness of the base plate 1, prevents the structural strength of the base plate 1 from being weakened by penetration, and also allows the base plate 1 to be laid flat. In addition, this structure allows for quick installation and disassembly, simplifying the tooling assembly process.

[0031] In some embodiments, the connecting block 2 is provided with a threaded hole that penetrates the connecting block 2. The bottom plate 1 is also provided with the same threaded hole as the connecting block 2 on its surface facing the connecting block 2. The depth of the threaded hole in the bottom plate 1 is less than the thickness of the bottom plate 1. When the connecting block 2 is detachably connected to the bottom plate 1, a screw 3 that extends into the bottom plate 1 is threadedly connected to the connecting block 2.

[0032] The design of the threaded hole and screw 3 further enhances the stability of the component connection, while maintaining the overall strength of the base plate 1 and allowing it to be laid flat. The removable nature of the screw 3 makes the component highly maintainable and reusable, helping to reduce operating costs.

[0033] In some embodiments, an anti-slip pad is attached to the surface of the base plate 1 facing away from the connecting block 2. The anti-slip pad is either a rubber pad or a silicone pad.

[0034] The anti-slip pad design enhances the anti-slip performance of the calibration fixture during operation, making it suitable for various work surfaces and further improving the safety and operational accuracy of the fixture.

[0035] In some embodiments, a cushioning pad, which is a rubber pad, is attached to the groove surface.

[0036] The buffer pad can effectively protect the surface of the deformed part and avoid scratches or damage caused by direct contact with the hard material of the support block 4. At the same time, it plays a role in absorbing vibration and buffering during the correction process, thus improving the durability of the tooling.

[0037] In some embodiments, with the center point of the base plate 1 as the center, at least 24 sets of connecting blocks 2 are detachably connected to the base plate 1. With the center point of the connecting block 2 as the reference, the included angle between adjacent sets of connecting blocks 2 is 15°. Each set of connecting blocks 2 includes at least one connecting block 2. The center of each connecting block 2 in the same set is on the same straight line as the center of the circle. They are sorted according to their distance from the center of the circle. Connecting blocks 2 with the same sorting in different sets are located on the same ring.

[0038] This design allows for precise positioning of the connecting block 2, enabling the tooling to adapt to the correction requirements of circular or annular deformable parts. Furthermore, the modular arrangement enhances operational accuracy and flexibility. When the deformable part is a stator frame, each support block 4 distributes the correction pressure, ensuring uniform stress on the deformable part during correction.

[0039] In some embodiments, there are 24 connecting blocks 2 that are farthest from the center of the circle. Each connecting block 2 is detachably connected to a support block 4, and the end faces of each support block 4 are located in the same plane.

[0040] By rationally distributing the positions of connecting block 2 and support block 4, multiple points of support can be provided for deformable parts in a plane, ensuring the uniformity of force during the correction process and adapting to the correction needs of various deformable parts.

[0041] In some embodiments, the ring containing the connecting block 2, which is closest to the center, is defined as the first ring. The pressing block 5 is arc-shaped, and the shape of all pressing blocks 5 spliced ​​together is defined as the second ring. The second ring has the same diameter as the first ring.

[0042] The design of the pressing blocks 5 forming a complete circular ring allows them to conform to the inner edge of the deformed part for uniform correction and effectively avoids localized deformation problems that may be caused by single-point stress. In addition, while keeping the number of pressing blocks 5 constant, they can be placed at different positions at different distances to distribute the correction pressure among the pressing blocks 5.

[0043] In some embodiments, when the deformable part is a stator frame, the surface of the stator frame that contacts the support block 4 is defined as the first frame surface, the surface of the stator frame that faces away from the support block 4 is defined as the second frame surface, the end face of the support block 4 is attached to the outer edge of the first frame surface, and the pressing block 5 is attached to the inner edge of the second frame surface.

[0044] By using a double-sided bonding support and correction method, forces can be applied simultaneously to the inner and outer edges of the stator frame, resulting in high correction efficiency and better accuracy, making it particularly suitable for the correction needs of complex structures.

[0045] In some embodiments, the base plate 1 is circular, and scale lines are provided on the edge of the base plate 1 to indicate the position of the connecting block 2 on the base plate 1.

[0046] The design of the scale lines provides a clear reference for the rapid positioning of the connecting block 2, significantly reducing tooling adjustment time and improving the standardization and consistency of operation.

[0047] The operation steps of a multi-purpose calibration fixture provided in this embodiment are as follows: Determine the arrangement of connecting block 2 and support block 4 according to the shape and size of the deformed part; fix the base plate 1 on the workbench and install connecting block 2 and support block 4 according to the scale lines and included angle requirements; place the deformed part on the end face of support block 4 and place pressing block 5 on the side of the deformed part facing away from support block 4; apply calibration pressure to pressing block 5 using a pressure device until the deformed part returns to the designed shape.

[0048] The initial tooling production took an average of about 8 hours for products of different specifications. The assembly of the multi-purpose calibration tooling provided in this embodiment of the utility model only takes 10 minutes, which improves work efficiency and saves ineffective costs in actual production.

[0049] In summary, this utility model provides a multi-purpose calibration fixture that achieves rapid assembly and disassembly through modular design, adapting to the calibration needs of deformed parts of different specifications and shapes, while improving the fixture's service life and economy. The detachable connection of the base plate 1, connecting blocks 2, and support blocks 4 allows for flexible assembly of the fixture, accommodating workpieces of different specifications and avoiding the need for separate fixture design for each specification, thus saving manufacturing costs. The designed combination structure of the connecting block group 2, support blocks 4, and pressing blocks 5 allows for rapid setup and adjustment of the calibration device, significantly reducing assembly and disassembly time and improving production efficiency. A buffer pad is provided in the groove of the support block 4, and an anti-slip pad is provided on the back of the base plate 1, effectively protecting the workpiece surface from damage and ensuring the stability of the fixture during use. With the center point of the base plate 1 as the center, the grouped connecting blocks 2 and support blocks 4 achieve universal calibration of workpieces of different shapes and specifications, suitable for the calibration of flotation machine stator frames. This invention provides a multi-purpose correction fixture that solves the problems of difficult assembly and disassembly, poor adaptability, and short service life of existing correction fixtures, offering an efficient, economical, and reliable solution for deformation correction in industrial manufacturing processes. Furthermore, through its rational structural design, this invention positively promotes efficiency and cost optimization in industrial production.
