Abstract

The utility model relates to a universal desk threading machine which belongs to the machining technology. A threading machine used at present has the disadvantages of large volume, complex structure, and high cost, which can not borne by medium and small-sized enterprises. Using a small desk tapping machine also has very low work efficiency, and the tapping is only in but not backward. The universal desk threading machine of the utility model has an additional suit of drive gear mechanisms on the basis of a desk drill, and the drive gear mechanisms are composed of clutches and tap chucks. The utility model has the advantages of simple structure, low cost, and convenient operation.

Description

Universal desk threading machine

The utility model is a kind of omnipotent bench tapping machine, belongs to the machined field.

The tapping machine volume of Shi Yonging is big now, complex structure, cost height.For general medium-sized and small enterprises is unaffordable.It is very low again to utilize small-sized bench drill to do tapping machine efficient, and its tapping can only be advanced, and can not move back.

In order to overcome the above-mentioned deficiency of tapping machine, the threading apparatus that a kind of volume is little, simple in structure, cost is low and efficient is high is provided, the utility model spy has proposed a kind of omnipotent bench tapping machine.

Omnipotent bench tapping machine of the present utility model is to increase a cover drive gear mechanism, clutch and screw tap dop to constitute on the basis of bench drill; Driving gear is associated in the bench drill main shaft; Driven gear forms a driving-chain by some guide wheels and driving gear; Clutch and screw tap dop join together, place between master, the driven gear, and pass driven gear; All gears all are associated on the shell, and shell and bench drill main shaft link, can be with the together lifting of bench drill main shaft.Clutch is that two ends are the revolving body of the conical surface.On master, the driven gear inner conical surface is arranged.

During the work of this machine, screw tap is stuck on the screw tap dop, the handle of pulling bench drill downwards moves down the main shaft of bench drill, drives whole gear transmission chain and moves down.Screw tap withstands on the workpiece, by the screw tap dop clutch is withstood, and when driving gear drops to the clutch position contacting, by friction drive clutch, screw tap dop and the screw tap rotation of the conical surface between them, can carry out tapping.During withdrawing, upwards pull the bench drill handle, make on the gear transmission chain and move, driving gear and clutch break away from, and driven gear contacts with clutch, drives clutch, screw tap dop and screw tap by driven gear by friction to do return motion, i.e. withdrawing.Description by the said structure and the course of work as can be seen, this machine is simple in structure, the advance and retreat cutter is convenient, cost is low.This machine just increases set of gears driving-chain and clutch and screw tap dop on existing bench drill.

Fig. 1 is the structural representation of omnipotent bench tapping machine of the present utility model.

Among the figure: (1) motor, (2) belt drive unit, (3) bench drill main body, (4) handle, (5) bench drill main shaft, (6) driving gear, (7) guide wheel, (8) guide wheel, (9) guide wheel, (10) follower, (11) clutch, (12) screw tap dop.

Embodiment: see Fig. 1

Omnipotent bench tapping machine of the present utility model is to increase a cover drive gear mechanism, clutch and screw tap dop to constitute on the basis of bench drill; Driving gear (6) is associated in bench drill main shaft (5); Driven gear (10) forms a driving-chain by guide wheel (7), (8), (9) with driving gear (6); Clutch (11) joins together with screw tap dop (12), places between driving gear (6), the driven gear (10), and passes driven gear (10); All gears all are associated on the shell (not drawing among the figure), and shell and bench drill main shaft (5) link, can be with together lifting of bench drill main shaft (5).Clutch (11) is that two ends are the revolving body of the conical surface.Driving gear (6), driven gear have inner conical surface on (10).
