Axis co-planar.To avoid interference with, the small slide plate of center lathe 26 is removed.
Operation principle of the present invention for the fixture of engine lathe processing bolt sphere：
First, bolt sphere 29 is tightened to by benchmark threaded hole on trunnion axis 6, since worm-drive has self-locking
Property, therefore bolt sphere 29 can be held with both hands and carry out this operation, it can prevent bolt sphere 29 from slipping out of the hand and causing center lathe 26
Guide rail, lathe bed are smashed even operating personnel and are injured by a crashing object.
Then, knob 24 is turned so that transmission shaft 11 rotates, and the first frictional disk 16 contacts (such as with the second frictional disk 17 at this time
Shown in Fig. 2), the rotation of transmission shaft 11 passes to vertical angle scale 3 by worm screw 7 and worm gear 8, by vertical angle scale 3 and stands
The rotation angle of scale control vertical angle scale 3 on plate 5, target angle, this process are arrived until vertical angle scale 3 is adjusted
In, locking pin 13 slides in arc through slot 19.
After the angular adjustment of vertical angle scale 3, handle 25 is pulled in lifting upwards, so that eccentric wheel 14 is reversely rotated, this mistake
Cheng Zhong, due to gradual at a distance from pivoting point of the contact point to eccentric wheel 14 with locking pin 13 of eccentric wheel 14 and horizontal angle scale 2
Reduce, therefore, locking pin 13 moves down a distance, so that the distance between eccentric wheel 14 and locking plate 20 is increased, horizontal angle scale 2
It is unlocked with pedestal 1.Meanwhile the leverage of eccentric wheel 14 makes shift fork 15 move down, shift fork 15 drives the first friction pulley 16 to move down, and makes
First friction pulley 16 contacts (as shown in Figure 5) with third friction pulley 18.Knob 24 is turned so that the rotation of transmission shaft 11, transmission shaft 11
It drives 9 rotation of star gear train, star gear train 9 to revolve round the sun around sun gear 10 and horizontal angle scale 2 is driven to rotate, passes through level angle
The rotation angle of scale controlled level angle scale 2 on disk 2 and pedestal 1, until the target angle that horizontal angle scale 2 is adjusted.
After the angular adjustment of horizontal angle scale 2, handle 25 is pulled in pressing, and eccentric wheel 14 is made to rotate in the forward direction, during this,
Due to gradually increasing at a distance from pivoting point of the contact point to eccentric wheel 14 with locking pin 13 of eccentric wheel 14 and horizontal angle scale 2,
Therefore, locking pin 13 moves up a distance, by horizontal angle scale 2 and the extruding of pedestal 1 be locked at eccentric wheel 14 and locking plate 20 it
Between.
Carry out the left and right feeding of bolt sphere 29 and front and back feeding, center lathe 26 respectively by sliding box 28 and middle slide plate 27
Milling flat, drilling and tapping processing are carried out to bolt sphere 29.
The embodiment of the present invention is elaborated above in conjunction with attached drawing, but the present invention is not limited to above-mentioned implementations
Example, within the knowledge of a person skilled in the art, can also do without departing from the purpose of the present invention
Go out various change.
