Abstract

The utility model discloses a threading clamp which is a cylinder. One end of the cylinder is provided with an axial prism hole in which a sleeve is equipped. A screw hole is equipped in the sleeve. The sidewall of the sleeve is provided with an axial through groove. The sidewall of the cylinder is provided with a through axial long hole. The position of the axial through hole corresponds with the position of the axial through groove on the side wall of the sleeve. A nut sleeve is inserted in the axial long hole and the axial through groove. The outer wall of the nut sleeve, the axial long hole and the axial through groove are in sliding fit. A bolt is equipped in the nut sleeve. The bolt is used for supporting the taper shank of a screw tap for preventing rotation relative to the clamp. The threading clamp has the following advantages: simple structure, and easy manufacture. After the threading clamp is equipped on a power head of a threading machine, the length of a screw tap clamp is adjusted according to the depth of the machined hole. Thus the screw taps in small number of specifications as possible can be used. Threading on the hollow hole and deep hole can be performed.

Description

A kind of tapping clamp
Technical field
The utility model relates to the fixture that uses in a kind of machining, is specifically related to a kind of for the fixture on tapping machine.
Background technology
The kind of various clamping tools is a lot of in existing machining, especially often uses the frock of drill jig class when holing at drilling machine.Working (machining) efficiency is high, the machining accuracy high because drill jig has, so drill jig adds in tapping and also can advance normal use man-hour.Because the stroke of present tapping machine unit head is limited, and the length of screw tap is fixing length.Therefore, can only carry out tapping processing to more shallow or hole conventional depth with existing company and existing screw tap, be difficult for carrying out tapping processing for darker hole, because the unit head of tapping machine is limited to the distance of clamping platform, if the screw tap clamping that will grow is on the unit head of tapping machine, its processed workpiece will be difficult for again being fixed by clamping.And, if the length of screw tap long adding in tapping also easily fractureed man-hour.So be necessary to design and a kind ofly be convenient to that deep hole is carried out tapping and add the fixture of attacking.
