Abstract

The utility model relates to a lathe tapping jig, comprising a threading die and further comprising a threading die jacket, a pull rod of a threading die frame, a Morse taper sleeve, and a limiting screw. The threading die is fixedly arranged in one end opening of the threading die jacket, and the other end opening of the threading die jacket is fixed in one end opening of the pull rod of the threading die frame. A rod body at the other end of the pull rod of the threading die frame is arranged in a cylinder body of the Morse taper sleeve and is movably connected with the cylinder body of the Morse taper sleeve. The limiting screw passes through a bar-shaped through hole which is arranged in the Morse taper sleeve and is fixedly arranged on the rod body of the pull rod of the threading die frame. The lathe tapping jig disclosed by the utility model has the characteristics that: with the adoption of the lathe tapping jig, the precision of machining threads is high; the lathe tapping jig is convenient and fast, is particularly suitable for thread volume production and has very obvious efficiency. Compared with manually tapping and tapping in other manners, the tapping efficiency can be improved for many times and the reject ratio is extremely low.

Description

Lathe tapping tool

Technical field

The utility model relates to a kind of tool, particularly a kind of lathe tapping tool.

Background technology

In mould parts processing, often run into the triangle rib-loop (like M6-M20) of some different sizes, form or use the screw die artificial by the direct car system of lathe generally speaking, cumbersome, nonstandard and efficient is very low.

Summary of the invention

In view of the situation of prior art, the utility model provides a kind of lathe tapping tool of convenient and swift machining screw.

The utility model is for realizing above-mentioned purpose; The technical scheme of being taked is: a kind of lathe tapping tool; Comprise screw die; It is characterized in that: also comprise screw die chuck, die handle pull bar, Mohs conical sleeve, limited screw, said screw die is fixed in the port of screw die chuck, and said screw die chuck another port is fixed in the port of die handle pull bar; Die handle pull bar other end shaft places not press in the conical sleeve stack shell and flexibly connects, and said limited screw passes the strip through-hole that the Mohs conical sleeve is provided with and is fixed on the shaft of die handle pull bar.

The characteristics of the utility model are: adopt this tool machining screw precision high, convenient, quick, the particularly suitable screw thread is produced in batches, and efficient is quite obvious, and it is extremely low to improve several times and fraction defective compared with manual tapping and other mode tapping efficient.

The specific embodiment

Like Fig. 1, shown in 2; A kind of lathe tapping tool; Comprise screw die 1; Comprise that also screw die chuck 2, die handle pull bar 3, Mohs conical sleeve 4, limited screw 5, said screw die 1 are fixed in the port of screw die chuck 2 through screw; Said screw die chuck 2 another port are fixed on through screw in the port of die handle pull bar 3, and die handle pull bar 3 other end shafts place not press in conical sleeve 4 stack shells and flexibly connect, and said limited screw 5 passes strip through-hole 4-1 that Mohs conical sleeve 4 is provided with and is spirally connected and is fixed on the shaft of die handle pull bar 3.

The internal diameter of screw die chuck 2 front ports is not the size of fixing, and can set according to the screw die 1 of different size, can make the screw die cover 2 of plurality of specifications.

The concrete operations explanation:

Partly be installed in Mohs conical sleeve 4 taper shanks of tool in the tail stock; With screw die 1 usefulness holding screw fixing with screw die cover 2 on; The lathe chuck center of clamping workpiece and tool are in one in the heart, with workpiece external diameter car to required size, (as attacking the little 0.02mm of m6 thread external diameter car); Screw die 1 is little with the workpiece cutting resistance, is convenient to processing.

Workpiece (the workpiece front end needs chamfering) will slowly contact with screw die on the tool 1, about the about 20-30 commentaries on classics/per minute of lathe rotating speed, and generally can be according to gong tooth diameter adjustment rotating speed; Produce cutting force through workpiece rotation and screw die 1; Drive screw die pull bar 3 and move, the strip through-hole 4-1 of Mohs conical sleeve 4 and limited screw 5 effects are control institute tapping length, reach Len req after; (general M8-M20 tapping length can reach 200MM) withdrawed from screw die 1 in lathe counter-rotating capable of using.

Claims

1. lathe tapping tool; Comprise screw die (1); It is characterized in that: also comprise screw die chuck (2), die handle pull bar (3), Mohs conical sleeve (4), limited screw (5); Said screw die (1) is fixed in the port of screw die chuck (2); Said screw die chuck (2) another port is fixed in the port of die handle pull bar (3), and die handle pull bar (3) other end shaft places not press in conical sleeve (4) stack shell and flexibly connects, and said limited screw (5) passes the strip through-hole (4-1) that Mohs conical sleeve (4) is provided with and is fixed on the shaft of die handle pull bar (3).
