Double-sided machine dial adjustment structure

Abstract

The invention relates to the field of large circular knitting double-sided knitting machines, in particular to the needle plate adjustment structure of the double-sided machine, which includes locking screws, a hollow screw cover set on the locking screw, and a hollow screw cover set under the hollow screw cover and set on the locking screw. The locking block of the screw, the locking screw passes through the support plate and is locked on the upper dial, the hollow screw sleeve is arranged in the through hole of the support plate, and the hollow screw sleeve is threadedly connected with the through hole of the support plate, so The bottom of the hollow screw jacket is provided with a "ten"-shaped groove, and the upper end of the locking block is provided with a "ten"-shaped convex key to match the "ten"-shaped groove. The "ten"-shaped convex key is inserted into the In the "ten"-shaped groove, due to the above-mentioned structure, this structure ensures the locking function of the locking screw, and makes it easy to adjust the flatness of the dial, ensuring the rigidity of the whole machine. All locking screws only Under simple tension, all locking blocks and threaded sleeves are tightly combined, while the upper dial is tightly connected to the support plate, and there will be no wave-like stress deformation, and the installation strength of the whole machine is higher.

Description

technical field [0001] The invention relates to the field of circular knitting double-sided knitting machines, in particular to the adjusting structure of the needle disc of the double-sided machine. Background technique [0002] For a long time, in the traditional technology, in the double-sided machine series of large circular knitting machines, the fixed installation and adjustment methods of the upper dial are relatively rough. As we all know, the upper dial 1 needs to correct its radial runout and end face runout before operation. like figure 1 , figure 2 , image 3 As shown, the fixing and adjustment method of the upper dial 1 depends on a circle of fastening screws 11, and at the same time, a pair of stop screws 12 are distributed on both sides of each fastening screw 11 for adjusting the upper dial 1. Circle beating. While adjusting the stop screw 12, tighten all fastening screws 11. The biggest defect of this method is that there is a certain distance between...

AI Technical Summary

Problems solved by technology

The biggest defect of this method is that there is a certain distance between the fastening point and the adjustment support point. On the one hand, due to the effect of stress deformation, when the dial is in a fixed state, the flatness of the end face of the dial has a certain influence, thereby reducing the The assembly accuracy of the whole machine; on the other hand, in order not to affect the assembly accuracy as much as possible, the installer cannot lock the fastening screw 12 too tightly, which affects the rigidity of the whole machine
