Summary of the invention
The technical problem that the utility model will solve provides a kind of accurate positioning, protecgulum simple to operate, easy to use finds positive frock.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of protecgulum centering frock comprises positioning sleeve, tensioner cover, connects the spiral shell dish and is connected handle; The center of said positioning sleeve front end is provided with alignment pin, and the outside of said positioning sleeve is provided with boss, said positioning sleeve and the said spiral shell dish pin-connect that is connected; The said tensioner cover front end outside is provided with the retaining platform that is complementary with said boss; The center, rear end of said tensioner cover is provided with said and is connected the tensioner cover internal thread through hole that handle is connected; The outside of said tensioner cover internal thread through hole is provided with equally distributed three spring conductor rods on the same circumference; The center of said connection spiral shell dish is provided with said and is connected the connection spiral shell dish internal thread through hole that handle is connected; The outside of said connection spiral shell dish internal thread through hole is provided with a guide post through hole, and said tensioner puts and is provided with the guide post that is complementary with said guide post through hole, and said connection spiral shell dish, tensioner cover and connection hand arbor are to successively through being threaded.
As optimal technical scheme, the utility model has also adopted following technical characterictic:
The sidewall of said alignment pin is provided with the taper bolt that is used to bear the tensioner active force.
The tapering of said taper bolt is 5 °.
Said taper bolt is four.
The outside of said alignment pin also is provided with the equally distributed repeated hole that goes.
The said repeated hole that goes is four.
Also comprise the location spacer block, be provided with in the middle of the spacer block of said location with said and be connected the location spacer block internal thread hole that handle is connected that said location spacer block is connected through being connected handle with the rear end that said tensioner is overlapped.
Advantage and the good effect that the utlity model has are: one, through adopting alignment pin, can guarantee the axiality of protecgulum hole and master gear well, improve the work quality of centering frock; Have characteristics simple to operate, easy to use simultaneously, greatly improved operating efficiency; Two, remove repeated hole through arranged outside, greatly reduced the weight of the utility model at alignment pin.
