Abstract

The utility model belongs to a simple interchangeable manual thread tapper, which comprises a BT50 tool shank (7), a pull nail (8), a Mohs taper shank (6) and a screw tap cutting sleeve (2), and is characterized in that: a thread tapper sliding shaft (5) is fixedly welded on the Mohs taper shank (6); a thread tapper sleeve (4) is movably arranged on the thread tapper sliding shaft (5), and is provided with a sliding chute (3); blocking screws (9) are in threaded connection with the thread tapper sliding shaft (5) and the inside of the sliding chute; and the left end of the thread tapper sleeve (4) is fixedly connected with the screw tap cutting sleeve (2) through a bolt I. Due to the adoption of the simple interchangeable manual thread tapper, the problems of difficulty in tapping in various forms with a digital display machine tool and insufficiency for processing a non-standard threaded hole tool with a numerical control digital machine tool are solved; and the simple interchangeable manual thread tapper has a simple structure and high processing accuracy, and is convenient for operating.

Description

Simple and easy exchange hand tapping device

Technical field

The utility model belongs to the machining tapping machine, particularly a kind of simple and easy exchange hand tapping device.

Background technology

At present, common digital display boring machine can't programme boring and tapping, particularly to the tapping aspect, generally all use the top screw tap that holds out against, carry out hand tapping with spanner, working (machining) efficiency is low, complicated operation, labour intensity is big; In off-gauge hole process of Digit Control Machine Tool processing, be difficult to buy the rigid tapping device that is complementary, and its interchangeability is poor, can not adapt to the requirement of all size.

Summary of the invention

The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of simple in structure, easy to process, cost is low, the simple and easy exchange hand tapping device that tapping efficient is high.

The technical scheme that the utility model technical solution problem is adopted is: a kind of simple and easy exchange hand tapping device; Comprise BT50 handle of a knife, blind rivet, Morse taper shank and screw tap cutting ferrule; It is characterized in that thread tapper sliding axle of fixing welding on the Morse taper shank; On the thread tapper sliding axle, adorn a thread tapper sleeve versatilely, on the thread tapper sleeve, be provided with sliding tray, on the tapping sliding axle, be connected a gear screw with the sliding tray internal thread; Be fixedly connected a screw tap cutting ferrule at thread tapper sleeve left end with bolt one.

The beneficial effect of the utility model is: this simple and easy exchange hand tapping device has solved the difficult problem of all size company of digital display lathe; Solved the not enough problem of Digit Control Machine Tool processing odd-pitch screw spot facing cutter; Simple in structure, easy to operate, interchangeability is good, and expense is low, and machining accuracy is high.

Description of drawings

Specify with embodiment below in conjunction with accompanying drawing.

Accompanying drawing is simple and easy exchange hand tapping device front view;

Among the figure: the 1-screw tap; 2-screw tap cutting ferrule; The 3-sliding tray; 4-thread tapper sleeve; 5-thread tapper sliding axle; The 6-Morse taper shank; The 7-BT50 handle of a knife; The 8-blind rivet; 9-gear bolt; 10-bolt one; 11-bolt two.

The specific embodiment

Embodiment; With reference to accompanying drawing, a kind of simple and easy exchange hand tapping device comprises BT50 handle of a knife 7, blind rivet 8, Morse taper shank 6 and screw tap cutting ferrule 2; It is characterized in that thread tapper sliding axle 5 of fixing welding on Morse taper shank 6; On thread tapper sliding axle 5, adorn a thread tapper sleeve 4 versatilely, on thread tapper sleeve 4, be provided with sliding tray 3, on tapping sliding axle 5, be connected a gear screw 9 with sliding tray 3 internal threads; Be fixedly connected a screw tap cutting ferrule 2 at thread tapper sleeve 4 left ends with bolt 1.On screw tap cutting ferrule 2, fix screw taps 1 with bolt 2 11; Adorn a blind rivet 8 at the right-hand member of BT50 handle of a knife 7.Not cooperating there to be friction between thread tapper sleeve 4 and the thread tapper sliding axle 5 is as the criterion.

During tapping simple and easy exchange hand tapping device is installed on the main shaft of the positive and negative rotation of ability, during the main shaft positive rotation, screw tap 1 carries out tapping automatically, and during counter-rotating, screw tap 1 screws out.

This simple and easy exchange hand tapping device has well solved with the various tapping difficulties of digital display machine tooling with the not enough difficult problem of Digit Control Machine Tool processing odd-pitch screw spot facing cutter; Simple in structure, easy to operate, machining accuracy is high.A kind of simple and easy exchange hand tapping device that welcome by the staff.

Claims (1)
