Further, two slotted cheese head screws are located at the left and right sides at the positioning disc center respectively, are in
It is symmetrical.
The operation principle of the utility model is as follows：
During clamping, directly circuit breaker base to be processed is sleeved on positioning plate, by positioning disc and short finger setting,
Determine U-shaped waist milling angle, simple in structure finally by the movable board clamping on flat-nose pliers moving jaw, dress
It tears open conveniently.During processing, circuit breaker base set after milling is complete is removed and turns over 87.6 ° of milling opposite sides by original position by first milling one side.
The beneficial effects of the utility model are：
1st, the utility model first passes through short pin, positioning disc is positioned, and determines the milling angle of U-shaped waist, then passes through peace
Movable board clamping on flat-nose pliers moving jaw by the Positioning Precision Control element precision of fixture in itself, ensures processing
Quality, and convenient mounting and clamping, production efficiency greatly improve, and thoroughly solve the U-shaped waist of high-voltage alternating sulfur hexafluoride breaker pedestal
Processing problem.
2nd, the utility model disperses manufacturing procedure, the wide 17.2mm's, 87.6 ° of angle on independent processing circuit breaker base
U-shaped waist, the content of processing is seldom, can rationally utilize existing equipment.
3rd, the utility model requires worker's technology relatively low, can take most rational cutting data, reduces the time kept in reserve, carries
High efficiency reduces production cost.
4th, the utility model has the advantages of simple structure, easily manufactured, and material therefor is 45 steel, and excellent cutting performance, manufacture is at low cost,
And it is easy to operate, securely and reliably.
