Abstract

The utility model discloses a device for the screw hole in machine work. Two friction cone pulleys which have the opposite rotation direction are meshed with the main shaft of the tapping, which realizes the working procedure of the cutting of the tapping and the return of the tapping. The utility model has the prominent advantages that the gear wheels, the bevel gears and the planetary wheels of various tapping devices which are presently adopted at home and abroad are not used, and the reverse direction carried out by the friction plate structure is not used; the utility model boldly adopts a cone wheel with novel fabrication process and simplicity to carry out the reverse direction, and thus the difficulty of the manufacturing and the cost are reduced. Simultaneously, as the cone pulley drives, the smoothness is improved than the driving of the gear wheel.

Description

Positive and negative rotation tapping apparatus
The utility model is machined threads hole on drilling machine, and it does not need the drill press spindle counter-rotating, realizes moving back a kind of device of silk work by thread tapper main shaft self counter-rotating.
Technique known, design to China Changchun 1017 mailbox, 47 branch mailboxes disclosed " novel three attack the energy tap holder " and domestic Jilin Province Jilin ginger justice as the U.S., the patent No. is that CN87205657U is from moving back a thread tapper, the patent No. of Shanghai City factory design is CN87207071U " an automatic control degree of depth automatic reverse tapping folder ", the patent No. of the north of the Changjiang River, Chongqing king's lofty virtue design is that CN86204462U " can reverse thread tapper ", their common characteristic can both realize reversing and move back silk automatically, for this purpose, they have adopted planet circular system respectively, friction plate, spur gear, it is reverse that bevel gear carries out the tapping main shaft, but manufacture difficulty is big, the required precision height, the manufacturing cost height.
The purpose of this utility model is not use baroque planet circular system, friction plate, spur gear, bevel gear to carry out oppositely, and adopts the very simple garden of manufacturing process cone pulley to carry out oppositely, so manufacturing cost reduces greatly.
The utility model is owing to having adopted cone pulley reverse, so stable working improves (700-800 rev/min) essentially no vibration and noise when working greatly under high speed.
The utility model in use, the operator utilizes feel control rotating very sensitive, and can play the automatic protective effect of overload, has avoided the generation screw tap phenomenon that fractures at work.
Advantage of the present utility model is, can regulate contact pressure between the friction pulley by spring (9), also can the wearing and tearing of friction pulley be compensated automatically simultaneously, thereby prolonged service life of the present utility model.
The utility model is owing to have a self-centering dop at the tapping front-end of spindle, thus it can clamping M2-M10 scope in the screw tap of all size, thereby shortened non-cutting time, and can also clamping drilling bit carry out bore operation.
The utility model is compared with known technology, and its reliable operation is steadily simple in structure, low cost of manufacture, its long service life.
Accompanying drawing has been described embodiment of the present utility model:
The taper fit of the taper hole of machine tool chief axis and (4) is passed to power (4), and (5) and (4) fix with screw thread, and during tapping, the friction drum (6) on the tapping main shaft (7) meshes with the inner cone of cone pulley (5), thereby makes (7) just change tapping.After tapping puts in place, with portable moving drill press spindle ascent guidance handle, its main shaft is risen, tapping main shaft (7) is owing to deadweight moves down, the Lower Half of the friction drum (7) (6) just and the engagement of the inner cone of big cone pulley (2), and the rotation direction of (2) is undertaken oppositely by little cone pulley (3), withdraws from workpiece automatically so (7) tapping main shaft drives screw tap.Handle (8) is the usefulness that prevents shell (10) rotation.Spring (9) can be regulated the contact pressure between (2), (5), (3) by screw.

Claims (1)

1, a kind of rotating thread tapper is used for the main shaft of drilling machine, can realize two motions that direction of rotation is opposite, tapping when just changeing, move back silk during counter-rotating, it is characterized in that: have two cone pulley (2) and (5) that direction of rotation is opposite, its reversing-gear is made up of little cone pulley (3), the contacting pressure and can regulate by spring (9) of little cone pulley (3) and cone pulley (2), (5).
