Description

Clamping jaw processing machine of multifunctional wrench

Technical Field

The invention relates to the field of multifunctional wrench machining, in particular to a clamping jaw machining machine of a multifunctional wrench.

Background

The spanner is a commonly used installation and extracting tool, because the size of the fastener of dismouting is different, needs to change the spanner of different models, consequently has had various multi-functional spanners on the market now, nevertheless all has certain not enough.

These multi-functional spanners in the existing market are all overlapped with two spanners of different models together, and the spanner openings are all on the same central line, thus the thickness of the spanner is doubled, which is equivalent to a thickened fastening hole. Therefore, it is difficult to attach and detach a fastener or the like at a specific position using such a multi-function wrench. Taking dismouting valve bolt as an example, because the valve body of valve generally is oval or circular arch, the valve has packing box, handle etc. again, because the spanner of traditional multi-functional spanner is too thick, therefore the spanner pushes up on the valve very easily when the dismouting for the spanner can not stretch into the position of wanting the dismouting.

The multifunctional wrench can change the diameter of the wrench by changing the rotating angle between the clamping jaws, and can rotate workpieces with various diameters. However, the existing clamping jaw is generally processed in a semi-automatic mode, and full-automatic processing cannot be carried out.
