Description
Technical field
The utility model relates to numerically-controlled machine tool rest design field more particularly to it is a kind of using conjugate cam transmission it is hydraulic
Knife rest.
Background technique
Hydraulic motor driving indexing is usually used in traditional hydraulic tool rest structure, and end-toothed disc is accurately positioned, oil cylinder locking；
Pre-determined bit then using slide valve lever insertion push-down cam keyway form, due to the revolving speed of hydraulic motor be not it is constant, with
Pressure and flow are non-linear relations, so the stop position of hydraulic motor output shaft is not sufficiently stable, cause the coarse positioning of cutterhead
Inaccurate, double wedge and concave tooth position deviation are larger, do not arrive theoretical correct position deficient position, beyond theoretical correct along direction of rotation cutterhead
Position is overshoot；Cutterhead can shake when locking (from standard is not allowed), i.e., traditional hydraulic tool rest is easy to produce " overshoot " or " owes
Position " failure.
Utility model content
The purpose of the utility model is to overcome the problemss of the above-mentioned prior art, provide a kind of using conjugate cam transmission
Hydraulic tool rest.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of using the hydraulic of conjugate cam transmission
Knife rest, including hydraulic motor, hydraulic motor are mounted on hydraulic motor seat, and the output shaft of hydraulic motor is with the one of conjugation camshaft
End is connected, and the other end of conjugation camshaft is supported on bearing block and end connection sender ring, conjugation camshaft drive connecting traction wheel
Axis rotation, conjugation camshaft are equipped with the conjugate cam of 90 ° of two panels interval and reversed arrangement, interlock wheel shaft and are equipped with two column dislocation
45 ° and the uniformly distributed roll wheel assembly of the circumference quartering, conjugate cam and roll wheel assembly tight mesh interlock wheel shaft and pass through gear biography
Dynamic to drive main axis, one end of main shaft connects cutterhead, and the other end of main shaft connects induction wheel, and conjugation camshaft interlocks wheel shaft
It is mutually parallel with the shaft centre line of main shaft.
The conjugation camshaft uses integral structure, interlocks wheel shaft and uses integral structure.
The cutterhead connection is for the fluted disc to cutterhead indexing positioning.
The utility model has the advantages that the application is rotated using hydraulic motor driving conjugation camshaft, conjugation camshaft, which drives, interlocks wheel shaft
Rotation interlocks wheel shaft and drives main shaft rotation by gear drive again, and main shaft is connected with cutterhead, and cutterhead rotates with it to realize knife
The tool changing of frame, wherein induction wheel is used to confirm that sender to be unclamped in the locking of knife position number and oil cylinder, and sender ring is counted for tool changing, altogether
There is the conjugate cam of 90 ° of two panels interval and reversed arrangement on yoke camshaft, interlocking has two column dislocation 45 ° and circumference 4 etc. on wheel shaft
Divide uniformly distributed roll wheel assembly, conjugation camshaft and the transmission ratio for interlocking wheel shaft are i1=4；It is interlocked on wheel shaft and main shaft by changing
The transmission ratio i of gear pair2, it is combined into the knife rest of different station number, specific as follows:
i2=2, i12=i1×i2=8, eight stations
i2=3, i12=i1×i2=12, twelve-station
i2=1.5, i12=i1×i2=6, six stations
i2=2.5, i12=i1×i2=10, ten stations
In conclusion being driven for conjugate cam, idler wheel stops at any position of the arc section on conjugate cam, interlocks
Wheel shaft is all off in the initial position of arc section, i.e. the stop position of 10 output shaft of hydraulic motor is unstable, does not influence to interlock
The stop position of wheel shaft does not also influence the coarse positioning of cutterhead, therefore the knife rest of the application can be realized high-precision tool changing, Bu Huifa
Raw " overshoot " or " deficient position " failure.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Specific embodiment
Below with reference to Fig. 1, the utility model will be further described.
A kind of hydraulic tool rest being driven using conjugate cam, including hydraulic motor 10, hydraulic motor 10 are mounted on hydraulic horse
Up on seat 20, the output shaft of hydraulic motor 10 is connected with one end of conjugation camshaft 30, the other end support of conjugation camshaft 30
On bearing block 40 and the end connects sender ring 50, and conjugation camshaft 30, which drives, interlocks the rotation of wheel shaft 60, on conjugation camshaft 30
Conjugate cam equipped with 90 ° of two panels interval and reversed arrangement, gearing wheel shaft 60 is equipped with two 45 ° of column dislocation and the circumference quartering is equal
The roll wheel assembly of cloth, conjugate cam and roll wheel assembly tight mesh interlock wheel shaft 60 by gear drive and drive 70 turns of main shaft
Dynamic, one end of main shaft 70 connects cutterhead 80, and the other end of main shaft 70 connects induction wheel 90, and conjugation camshaft 30 interlocks wheel shaft 60
It is mutually parallel with the shaft centre line of main shaft 70.
The application drives conjugation camshaft 30 to rotate using hydraulic motor 10, and conjugation camshaft 30 drives gearing wheel shaft 60 to revolve
Turn, interlock wheel shaft 60 and the rotation of main shaft 70 is driven by gear drive again, main shaft 70 is connected with cutterhead 80, cutterhead 80 rotate with it from
And realize the tool changing of knife rest, wherein induction wheel 90 is used to confirm that sender to be unclamped in the locking of knife position number and oil cylinder, and sender ring 50 is used for
Tool changing counts, and has the conjugate cam of 90 ° of two panels interval and reversed arrangement on conjugation camshaft 30, and interlocking has the dislocation of two column on wheel shaft
45 ° and the uniformly distributed roll wheel assembly of 4 equal part of circumference, conjugation camshaft 30 and the transmission ratio for interlocking wheel shaft 60 are i1=4；Pass through change
Interlock the transmission ratio i of wheel shaft 60 and main shaft 70 gear pair2, it is combined into the knife rest of different station number, specific as follows:
i2=2, i12=i1×i2=8, eight stations
i2=3, i12=i1×i2=12, twelve-station
i2=1.5, i12=i1×i2=6, six stations
i2=2.5, i12=i1×i2=10, ten stations
Conjugate cam is driven, idler wheel stops at any position of the arc section on conjugate cam, interlocks wheel shaft 60 all
It is off in the initial position of arc section, i.e. the stop position of 10 output shaft of hydraulic motor is unstable, does not influence to interlock wheel shaft 60
Stop position, also do not influence the coarse positioning of cutterhead 80, therefore the hydraulic tool rest of the application can be realized high-precision tool changing, will not
