Description
Technical field
The present invention relates to a kind of pneumatic tapper, belong to field of mechanical technique.
Background technology
Tapping machine is exactly a kind of lathe with screw tap machining internal thread, and it is most widely used a kind of internal thread machining lathe.By national machinery industry standard, tapping machine series formation is divided into: bench tapping machine--semi-automatic bench tapping machine, vertical tapping machine, Horizontal tap.Because a kind of important classification be most widely used of certain reason excludes wherein, i.e. folding arm tapping machine, hydraulic pressure threading machine, electric threading machine, pneumatic tapper.Pneumatic tapper adopts compressed air-driven, safely and fast efficiently; The gentle amount of less atmospheric pressure (0.3-0.8mpa), super large torsion exports; . can to various steel, iron, copper, aluminium, plastic or other material tapping; Collet chuck band overload protection arrangement, screw tap damage is less, and thread precision is high; Simple to operate light, do not need experience and strength completely; Processing cost comparatively uses CNC machining center, milling machine band thread tapper or hand tapping much lower; Heavier working substance does not need positioner or movement, work area especially big (within the scope of radius 100-2000mm); Locate cutting speed fast and higher rapidly, increase output; Open-work or blind hole, all unlikely fracture of screw tap, vertical, (universal) angle all energy tapping; The range of work is large: (M3-M24).Product, the guarantee in service life.Existing tapping machine screw tap easily twists off, very large with tapping machine screw tap power section relation.
Summary of the invention
The invention provides a kind of pneumatic tapper, be a kind of Novel tapping machine, screw tap not easily twists off or damages.
For solving above technical problem, the invention provides following technical scheme: a kind of pneumatic tapper, comprise splined shaft, Connection Block, dust ring, inserts, cushion pad, spring, pushing ram assembly, deep groove ball bearing I, lining, pushing ram cover, large overcoat, O-ring seals, V-shaped seal ring, copper sheathing, deep groove ball bearing II, hexagonal locking nut, round nut, water seal, working shaft assembly, flat key, described pushing ram cover end connects one end of large overcoat, the other end of large overcoat is connected with Connection Block, pushing ram cover, large overcoat, enclosure space is formed between copper sheathing and Connection Block, spring is provided with in this enclosure space, push the shoulder presses spring of bar assembly, pushing ram assembly end withstands on bearing outer ring, one end of the other end connecting bushing of bearing outer ring, strong axle axle sleeve is spent to be enclosed within outside the strong axle of China, splined shaft connects reductor main shaft, the shoulder of splined shaft axle sleeve connects on deep groove ball bearing II inner ring, the other end of lining connects the outer ring of deep groove ball bearing I, and the inner ring of deep groove ball bearing I connects round nut, and round nut is squeezed in the other end of deep groove ball bearing I outer ring, and the end of round nut adopts the pushing ram cover that is threaded.
Further, V-shaped sealing ring and O RunddichtringO is provided with between described copper sheathing and large overcoat.
Further, between described working shaft assembly and round nut, there is water-stop.
This pneumatic tapper that the present invention relates to, there will not be the problem that tapping is ruptured.
