AI Technical Summary

Technical Problem

In existing technologies, the needle plate insert grooves of ultra-dense needle knitting are too deep, which makes the processing difficult, the processing qualification rate low, and the milling cutter is prone to bending, deformation or breakage.

Method used

Positioning protrusions and clearance parts are set in the insert slot to reduce the machining depth of the insert slot. The connection strength of the insert is improved by positioning grooves, positioning wires and buckle structures. Combined with machining deformation grooves on the back of the needle plate to improve the deformation resistance of the needle plate.

Benefits of technology

It reduces the chipping and breakage of milling cutters during machining, improves machining accuracy and yield, and enhances the stability of inserts and the strength of the pin plate.

Abstract

This utility model discloses an improved dense needle plate, relating to the field of computerized flat knitting machine production technology. It includes a needle plate and a insert plate. The insert plate has an insertion slot, and positioning reference points are provided at both ends of the bottom of the insert plate. A clearance portion is provided between the two positioning reference points. A positioning protrusion is provided inside the insertion slot, and the shape of the positioning protrusion matches the clearance portion. The improved dense needle plate provided by this utility model reduces the machining depth of the insertion slot by adding a positioning protrusion inside the insertion slot. Simultaneously, the clearance portion on the insert plate, after the insert plate is inserted into the insertion slot, cooperates with the positioning protrusion. This reduces the machining depth of the insertion slot while ensuring the insertion plate's installation position remains unchanged, thus facilitating machining and reducing the risk of chipping or breakage of the milling cutter during machining. The machined insertion slot meets the precision requirements, improving the accuracy and yield rate of the insertion slot. The positioning reference points are retained at the bottom of the insert plate, fulfilling the basic functional requirements of the insert plate.
