Description

Balance compresses gear hobbing tooling and using method thereof
Technical field
The present invention relates to a kind of to avoid elongated mandrel that trace buckling phenomenon occurs after compaction, and dismount Quickly, labour-saving balance compress gear hobbing tooling and using method thereof, belong to gear hobbing tooling and manufacture field.
Background technology
CN 104625246 A, title " a kind of gear-hobbing clamp ", including clamp body, described clamp body upper end is provided with a lining Set, the downward boss of described lining coordinates with clamp body upper end center hole rows, described lining has a central through hole, this through hole In be provided with a gear hobbing mandrel, described gear hobbing mandrel one end is connected with lining lower end by locking nut, and the other end passes through nut It is fixedly connected with a spacer, described gear hobbing mandrel is additionally provided with a dismounting nut.It is provided with a tensioner on described gear hobbing mandrel Set, described expansion sleeve one end offsets with spacer, and the other end offsets with the boss on gear hobbing mandrel.Described gear hobbing core sleeve is connected on lining One end in set is No. five Morse taper shanks, this taper shank and lining interference fit.Described expansion sleeve is that elastic rubber material is made. Weak point: this kind of gear hobbing is clipped on mandrel and arranges nut to compress worm gear, and the most elongated mandrel compresses worm gear mistake at nut Journey there will be the bending of trace so that unclamp teeth directional V-value during spiral case making and become big, leverage the processing of the worm gear flank of tooth Precision.
Summary of the invention
Purpose of design: for avoiding the deficiency in background technology, design a kind of can not only avoid elongated mandrel compress After trace buckling phenomenon occurs, and dismount quickly, labour-saving balance compress gear hobbing tooling and using method thereof.
Design: for realizing above-mentioned purpose of design.1, described screw is installed with screw and after screw is screwed down Steel ball compresses the design of flat key, is one of the technical characteristic of the present invention.So purpose of design is: by worm gear to be processed After centering is arranged on the centering spindle nose of mandrel, flat key is inserted in the square hole of mandrel and screw is screwed down and make flat key at steel Compress worm gear under the extruding of ball, worm gear Fast Installation can be realized;After spiral case making, screw is upwards unscrewed and will put down Key is extracted from square hole and can quickly be unloaded from centering spindle nose by worm gear;One is that this compressing structure is not only simple in structure, and Dismounting rapid and convenient;Two are owing to only need to can extract flat key somewhat loosening for screw during dismounting worm gear so that worm gear is dismantled more Laborsaving;Three is tightening screw by steel ball is transferred to flat key by power and stress point is distributed on the axis of mandrel, the most not Only ensure that compression effect, and it can be avoided that elongated mandrel trace buckling phenomenon occurs during compressing worm gear, thus Unclamp teeth directional V-value when solving spiral case making and become big problem.2, the lower port of through hole is the design of bell, is the present invention The two of technical characteristic.So purpose of design is: owing to the lower port of through hole is bell and lays steel ball in through-holes Bulb diameter is more than the diameter of bell, and during compressing worm gear, when flat key inserts square hole, flat key is by steel ball fight back through hole, And the upper surface of the flat key inserted in square hole is pushed down in steel ball its lower end under gravity, flat key is so made quickly to save In the insertion square hole of power;The port of taper simultaneously is prevented from steel ball and stuck phenomenon occurs with port under the extruding of screw.3、 Described mandrel upper end be centering spindle nose design, be the present invention technical characteristic three.So purpose of design is: described Mandrel upper end is centering spindle nose, and centering spindle nose is installed for worm gear centering.4, described screw is the design of countersunk head screwed hole, is The four of the technical characteristic of the present invention.So purpose of design is: described screw is countersunk head screwed hole, and countersunk head screwed hole is not only used In spinning screw, and can be easy to top withstand mandrel upper end.
Technical scheme 1: a kind of balance compresses gear hobbing tooling, including mandrel, described mandrel upper end for centering spindle nose and Centering spindle nose is inverted T-shaped, and described centering spindle nose upper surface vertically has screw, and described centration axis rostral face laterally has through two The square hole of side wall surface and square hole are positioned at immediately below screw, vertically have through hole and through hole upper end is passed through with screw at the bottom of described screw hole Logical, lower end is through with square hole, the lower port of this through hole is bell, is provided with steel ball and steel ball bulb diameter more than boring in described through hole The diameter of shape mouth, is provided with the height of flat key and flat key less than square hole height in described square hole, described screw is installed with screw and After screw is screwed down, steel ball compresses flat key.
Technical scheme 2: a kind of balance compresses the using method of gear hobbing tooling, step one: by worm gear suit to be processed On the centering spindle nose of mandrel, and worm gear installation site is finely adjusted, it is ensured that worm gear centering is installed;Step 2: flat key is inserted Enter in the square hole of mandrel, then screw is screwed down and makes flat key compress worm gear under the extruding of steel ball;Step 3: enter at worm gear After row processing, screw is upwards unscrewed, then flat key is extracted from square hole;Step 4: worm gear is unloaded from centering spindle nose.
The present invention is compared with background technology, and one is that in balance compression gear hobbing tooling, power is transmitted by tightening screw by steel ball It is distributed on the axis of mandrel to flat key and stress point, it is possible to avoid elongated mandrel to occur during compressing worm gear micro- Amount buckling phenomenon;Two is that balance compression gear hobbing tooling is not only simple in structure, and dismounts quick, laborsaving.
