AI Technical Summary

Technical Problem

The connecting head of the existing high-hardness tap is a whole and cannot be disassembled, resulting in the need to replace the entire tool when the tap head is damaged, which increases the cost and cannot replace the model size of the tap port and the electric gun barrel.

Method used

A high-hardness tap for replaceable connectors is designed, including a tap head, a connecting rod and a connecting seat. The tap head can be removed and installed by unscrewing the fixing bolts to achieve model replacement, and the strength and corrosion resistance of the tap head are improved through titanium alloy and corrosion-resistant layer.

Benefits of technology

The model replacement of the tap head is realized, avoiding the replacement of the entire tool, saving costs, and improving the strength and service life of the tap head through the use of titanium alloy and corrosion-resistant layer.

Abstract

The utility model relates to the technical field of high-hardness screw taps, and discloses a high-hardness screw tap with a replaceable connector, which comprises a screw tap head, a connecting rod and a connecting seat, and four thread strips are arranged on the outer ring of the screw tap head; a limiting column is arranged in the middle of the front end of the connecting base, four clamping blocks are arranged on the outer ring of the connecting base, connectors are installed at the rear ends of the clamping blocks, a notch is formed in the middle of the rear end of the connecting rod, and the connecting base is connected with the notch in a clamped mode. By unscrewing the four fixing bolts, the first mounting plate and the second mounting plate are disassembled, so that the type of the screw tap head can be replaced, the whole body is prevented from being replaced, the cost is saved, convenience is brought, and the connector can be used for replacing different types of gun barrels of the electric gun without limitation.
