Description
Technical field
The invention belongs to field of machining, and in particular to a kind of screw pair grinding tool is applicable in more particularly to one kind
Grinding tool is matched in large pitch high-precision multi-head spiral pair.
Background technique
For the linear motion of piston rod to be converted to the tooling of rotation using screw pair, it is desirable that screw pair gear motion is suitable
Freely without bite, screw pair field of conjugate action degree of engagement is not less than 80%, and surface roughness is not higher than Ra0.8.Usual helical axis helicla flute
It is shaped using number Milling Machining, spiral sleeve helical axis is shaped using electrical discharge machining, the initial surface roughness and engagement of the two
Degree is poor, needs the two carrying out pairing grinding.Hand lapping mode is originally used, every set screw pair needs to grind thousands of
Secondary, about 2 days time-consuming, labor intensity of workers is big, and grinding efficiency is lower.
Summary of the invention
The object of the present invention is to provide a kind of screw pair grinding tool, solve the problems, such as that screw pair grinding efficiency is low.
The technical solution of the present invention is as follows: a kind of screw pair grinding tool, it is characterised in that: including bottom plate 1, guide rail bearing 2,
Push rod 3, front-end bearing pedestal 7, rear bearing block 9, shaft 6, torsional spring 8；Guide rail bearing is fixed on bottom plate, and 3 one end of push rod, which is mounted on, leads
It is connect in the pilot hole of rail support with lathe or power end, does linear reciprocating motion；The other end of helical axis and push rod is connected；Turn
Axis 6 is mounted on forward and backward bearing block by front and back bearings；Torsion spring set is on the outside of shaft, between two bearings seat, by adjusting turning
The pretwist gyration of axis controls shaft load torque；Spiral sleeve is connect by key with shaft；5 phase of helical axis 4 and spiral sleeve
Cooperation.
The utility model has the advantages that the present invention drives helical axis to move along a straight line by the reciprocating feed movement of numerically-controlled machine tool, pass through
Screw pair engagement drives spiral sleeve crankmotion, while adding abrasive media on the field of conjugate action and realizing the screw pair field of conjugate action
Abrasive forming, the automatic grinding of screw pair is embodied as using simple mechanism, significantly mitigation labor intensity of workers, improve grinding
Efficiency and quality.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is shaft side figure of the invention.
Specific embodiment
To keep the purpose of the present invention, content and advantage clearer, a specific embodiment of the invention is made further detailed
Thin description.
The present invention provides a kind of screw pair grinding tool, including bottom plate 1, guide assembly, front-end bearing pedestal 7, rear bearing block 9,
Shaft 6, torsional spring 8；Guide assembly is mainly made of guide rail bearing 2, key, push rod 3, pin shaft, for realizing the reciprocating motion of push rod
And limit the rotation of push rod；
Guide rail bearing is fixed on bottom plate, cylindrical 3 one end of push rod be mounted in the pilot hole of guide rail bearing with lathe or
Power end connection, reciprocally moves along a straight line, and is machined with keyway in pilot hole and on push rod, prevents the two from relatively rotating by key.
Helical axis is connected by the other end of pin shaft and push rod；
Shaft 6 is mounted on front and back bearings seat by two groups of front and back bearing, and wherein fore bearing is used using angular contact ball bearing
In shaft radial positioning and axial thrust is undertaken, rear bearing is used for shaft radial positioning using deep groove ball bearing.Torsion spring set is turning
On the outside of axis, between two bearings seat, shaft load torque is controlled by adjusting the pretwist gyration of shaft, is ground for screw pair
When load and realize return move.Realize that pivot angle limits equipped with pin in shaft and using the screw on bearing block
Position.Spiral sleeve is connect by key with shaft；Helical axis 4 and spiral sleeve 5 match.
This tooling can be pressed on CNC milling machine workbench by pressing plate or be fixed on numerically controlled lathe by pull rod, crossbeam
On middle supporting plate, pass through the movement of control platen or middle supporting plate, push rod and lathe fixed main shaft component or lathe when work
Chuck is connected, and push rod is made to do relatively reciprocating motion with tooling base.
It when work, by spiral sleeve and helical axis according to tooth engagement is engaged in place, is mounted in shaft, is adjusted by key
Turn over axis rotates angle makes helical axis be combined with push rod and be connected with pin shaft with helical axis length of action.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
