Description

Technical Field

[0001] This utility model relates to the field of flat knitting machine frame production technology, and in particular to an adjustable polishing component and polishing equipment. Background Technology

[0002] After a certain number of years of use, knitting machines need to be upgraded. Simply recycling retired equipment as scrap would be wasteful. However, parts worn over time require polishing or replacement. While the base material of a knitting machine is relatively thick and intact, polishing is still necessary to ensure optimal performance. Furthermore, to meet market demands, the flat knitting machine frame (base) is typically cast and then polished manually. Manual polishing is time-consuming, labor-intensive, and inefficient, resulting in inconsistent precision. Therefore, specialized polishing equipment is needed to polish the triangular cross-section of the base. Utility Model Content

[0047] Example 3

[0048] Reference Figure 5 The difference between this embodiment and embodiment two is that: the upper end of the second transmission gear 34 is provided with a reset device, which includes a spring 36 and a fixing plate 37. The upper end of the spring 36 is connected to the fixing plate 37, and the lower end of the spring 36 is connected to the top of the second transmission gear 34. The spring 36 always applies a downward force to the second transmission gear 34, so that the second transmission rod can achieve grinding and polishing of the workpiece 14 without manual control.

[0049] Example 4

[0050] Reference Figure 1 and Figure 3 The difference between this embodiment and embodiment three is that: both the polishing device and the adjustable polishing component in embodiment one are provided in two. The frame 1 is provided with a gantry 3. The two polishing devices are a first polishing device and a second polishing device 15, which are respectively located on the left and right sides of the gantry 3. Two mounting seats are respectively located on both sides of the moving platform 8 and corresponding to the polishing devices, which facilitates the grinding and polishing of the workpiece 14, thereby realizing dual-station operation and further improving the grinding and polishing efficiency.

[0051] This embodiment further improves the efficiency of polishing workpiece 14 by setting up a dual-station polishing device and mounting base. The cooperation between the polishing device and the mounting base ensures the uniformity and precision of polishing the surface of workpiece 14, reduces the labor intensity of manual polishing, and improves the polishing effect.

[0052] In this invention, by setting a mounting base that matches the base of the knitting machine, the efficiency and effect of grinding and polishing the base of the knitting machine are effectively improved, the labor intensity of manual grinding and polishing is reduced, and the consistency and precision of grinding and polishing are guaranteed. By setting an adjustment handle 12 on the drive box 5, the grinding and polishing force can be manually controlled and adjusted according to the grinding and polishing needs, ensuring the grinding and polishing effect. By setting a spring 36 above the second transmission rod, the workpiece 14 can be automatically ground and polished under the elastic force of the spring 36, without the need for manual control of the pressure applied. When it is necessary to grind and polish local key points, the grinding and polishing force can be manually intervened, effectively ensuring the precision of grinding and polishing.

[0053] The working principle of this application is as follows: During use, the triangular knitting machine base is first installed on the mounting seat, and the workpiece 14 is limited by the end positioner 10, the side positioner and the side positioner to prevent the workpiece 14 from moving during the grinding and polishing process; after the workpiece 14 is installed, the upper surface of the workpiece 14 is ground and polished by the polishing device, and at the same time, the moving platform 8 moves along the slide rail 23 under the drive of the drive device. The diameter of the polishing disc 13 is larger than the width of the upper surface of the workpiece 14, so the grinding and polishing can be completed in one go. During the grinding process, the grinding and polishing force of the polishing disc 13 can be realized by manually adjusting and controlling the adjustment handle, thereby ensuring the effect and efficiency of grinding and polishing.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. In the absence of conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
