Description
Technical field
The present invention relates to the numerically controlled processing equipment of a kind of extra small screw-tap threaded, especially relate to a kind of extra small screw tap of double abrasive wheel
Screw grinder.
Background technology
The tap-grinding machine of current domestic tool industry, conventional is " machine-liquid-electricity " integral structure, and its structure is complicated, valency
Lattice are expensive, and are not specifically designed to the extra small screw tap special processing equipment producing M1-M6.
The extra small screw tap of external import produces equipment, and employing is all top clamping workpiece, and twice finishing is by with a piece of
Emery wheel completes processing.Because workpiece size is extra small, cause clamping workpiece difficulty, and be difficult to the most correct center hole；And
When required center hole diameter is less than 0.3mm, causes because workpiece threaded portion diameter is small and top quickly scrap；Two work step corrections
Not only waste emery wheel but also affect production efficiency.
Summary of the invention
To be solved by this invention haveing a problem in that overcomes the deficiencies in the prior art, it is provided that one decreases emery wheel waste and top
Point scrappage, improves the double abrasive wheel extra small screw-tap threaded grinding machine of production efficiency.
The present invention solves it and technical problem is that and take techniques below scheme to realize:
A kind of double abrasive wheel extra small screw-tap threaded grinding machine, feeding part, milled portion and workpiece the part that is installed is constituted, described in enter
Include that the axial feed mechanism of workpiece, emery wheel move radially pitch mechanism and helical angle automatic mechanism to part；Described mill
Cut part and include grinding spindle, the little emery wheel being connected with described grinding spindle, big emery wheel, the chuck parallel with described grinding spindle
Reconditioning main shaft, the left side of described chuck reconditioning main shaft is provided with collet automatic pneumatic bistrique, its medium and small emery wheel and big emery wheel
With one heart, parallel installation, be co-located at the left side of described grinding spindle, the ring flange of big emery wheel is provided with compensating groove, in compensating groove
Equipped with static organ；Described workpiece is installed and partly includes collet mechanism, the cylinder piston being connected with described collet mechanism
Bar, cooling body and collet cleaning air flue.
The described feeding axial feed mechanism of part workpiece and emery wheel move radially pitch mechanism and all use linear electric motors.
The medium and small emery wheel of described milled portion and the different diameters 15-20mm of big emery wheel, the two spacing is 20mm.
The present invention compared with prior art has significant advantage and a beneficial effect:
Use double abrasive wheel and collet clamped one time, the mode of division of labor step grinding, thus effectively reduce emery wheel waste and
Top scrappage, improves production efficiency, and emery wheel operates steadily, and precision is high.

The chuck reconditioning main shaft 10 that described grinding spindle is parallel, the left side of described chuck reconditioning main shaft is provided with collet automatic pneumatic
Bistrique 6, the installation concentric with big emery wheel, parallel of its medium and small emery wheel, it is co-located at the left side of described grinding spindle, the flange of big emery wheel
Dish is provided with compensating groove, and compensating groove is built with static organ；Described workpiece is installed and partly includes collet mechanism 5 and described bullet
Cylinder piston rod 12, cooling body 8 and the collet cleaning air flue 9 that spring chuck mechanism is connected.
The described feeding axial feed mechanism of part workpiece 1 and emery wheel move radially pitch mechanism 2 and all use linear electric motors.
The medium and small emery wheel of described milled portion 3 and the different diameters 15-20mm of big emery wheel 4, the two spacing is 20mm.
Above one embodiment of the present of invention is described in detail, but described content has been only the preferable enforcement of the present invention
Example, it is impossible to be considered the practical range for limiting the present invention.All impartial changes made according to the present patent application scope and improvement
Deng, within all should still belonging to the patent covering scope of the present invention.
