Axis co-planar.To avoid interference with, the small slide plate of center lathe 26 is removed.
Working principle of the utility model for the fixture of engine lathe processing bolt sphere:
Firstly, bolt sphere 29 is tightened on trunnion axis 6 by benchmark threaded hole, since worm-drive is with 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 operator 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, arrives target angle, this process 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, reversely rotates eccentric wheel 14, this mistake
Cheng Zhong, due at a distance from the pivoting point of eccentric wheel 14 and the contact point of horizontal angle scale 2 to eccentric wheel 14 and locking pin 13 gradually
Reduce, therefore, locking pin 13 moves down a distance, increases the distance between eccentric wheel 14 and locking plate 20, horizontal angle scale 2
It is unlocked with pedestal 1.Meanwhile the leverage of eccentric wheel 14 moves down shift fork 15, 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
9 rotation of star gear train is driven, star gear train 9 revolves around sun gear 10 and horizontal angle scale 2 is driven to rotate, and 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, rotates in the forward direction eccentric wheel 14, during this,
Due to being gradually increased at a distance from eccentric wheel 14 and the pivoting point of the contact point of horizontal angle scale 2 to eccentric wheel 14 and locking pin 13,
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 and front and back feeding of bolt sphere 29, 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 embodiments of the present invention are elaborated above in conjunction with attached drawing, but the utility model is not limited to
Embodiment is stated, within the knowledge of a person skilled in the art, the utility model aims can also not departed from
Under the premise of make a variety of changes.
