Position cover board is bonded with positioning runner on worm gear, while positioning cover plate is fixed with annular plate rail by screw；It empties and sets inside worm gear
Windmill is counted into, so that buckle sliding block is bonded the activity of its inner wall and non-interference, and buckle slider bottom and annular plate rail
On the inserted cooperation of radial groove, buckle sliding block can be made along the chute in annular plate rail internal diameter to movement, buckle sliding block one end band
There is small hook, catch on the groove on annular plate rail, the buckle sliding block other end and idler wheel are hinged.
It is emptied inside the worm gear and is designed to windmill, so that worm gear inner wall is bonded with buckle sliding block arc side when rotation,
Make worm gear when rotated while squeezing buckle sliding block, synchronizes it to the heart and non-interference to center movement realization simultaneously.
Three sliding slots radially, the constraint due to sliding slot to buckle sliding block, so that three are provided on the annular plate rail
Its movement in stress of buckle sliding block is radially carried out along annular plate rail always.
The worm gear side is provided with a circle positioning runner, so that positioning cover plate while positioning cover plate and fixed annular plate rail
On protrusion insertion worm gear positioning runner in, such worm gear will not be generated relative to annular plate rail in rotary course it is radial or
Person is axially moved.
The worm gear side is provided with groove, and the small hook after buckle sliding block can catch on the groove on worm gear, so that reversed rotation
When turning operation worm screw drive worm gear reset, buckle sliding block can also be pulled by worm gear to be resetted.
The utility model has the beneficial effects that (1) the utility model simplifies structure compared to conventional center frame, only with behaviour
Operating worm screw can be realized to heart clamping workpiece, alleviates the very complicated degree of operator's operation, improves centre frame
Service efficiency；(2) to the heart while the utility model can be realized centre frame for the special designing inside worm gear；(3) this reality
It is less than the angle of friction of worm and gear contact with the expansion helical angle that the cooperation of novel middle worm and gear meets worm screw, meets from bolt
Part, so that clamping completion to the heart in workpiece, operator also can guarantee that clamping workpiece does not loosen after loosing one's grip.
