Description

A kind of combination boring grab
Technical field
The utility model relates to machined field, particularly relates to a kind of combination boring grab.
Background technology
Butterfly valve is again flap valve, it is a kind of control valve simple in structure, the valve butterfly valve simultaneously also can be used in the mode work of switch control of low pressure pipeline medium refers to that closure member (flap or butterfly plate) is disk, rotate to reach a kind of valve of open and close around valve shaft, valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.On pipeline, main rising cut off and throttling action.Butterfly valve opening and closing element is a discoidal butterfly plate, and the axis around himself in valve body rotates, thereby reaches the object that opens and closes or regulate.
Butterfly valve, to add man-hour drilling operating more, uses same main shaft equipment, and each operation need to be joined a kind of fixture, and the input of equipment is more, and human cost is larger, has increased widely the production cost of butterfly valve.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of combination boring grab, can reduce the quantity of fixture, has reduced time and the number of times of thread-changing operation, has improved operating efficiency.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of combination boring grab is provided, comprise: base plate, main positioning datum, clamping device and protector, on described base plate, have screwed hole, between base plate and equipment, be threaded connection, main positioning datum is fixed on plate upper surface middle part, clamping device is arranged at the top of main positioning datum, the two ends of clamping device are provided with two through holes, the middle part of clamping device is provided with anti-interference hole A, the position of described anti-interference hole A is corresponding with main positioning datum, described protector is arranged at the both sides of main positioning datum, the medial surface of protector is adjacent to main positioning datum, protector is secured by bolts in base plate, the side of described protector also has anti-interference hole B.
Preferably, described combination boring grab is also provided with guide rod locating hole, in described guide rod locating hole, is provided with guide rod, and described guide rod is through the through hole at clamping device two ends, and guide rod overcoat has spring, and described spring is arranged at the top of clamping device.
Preferably, described base plate also has locating hole.
Preferably, the two ends of described base plate are also provided with briquetting, and base plate is compressed.
Preferably, the material of described main positioning datum is 9CrSi.
The beneficial effects of the utility model are: the utility model, compared with existing tool, has reduced tool quantity, has reduced thread-changing activity duration and number of times, and still less, tool is simply light, has improved working (machining) efficiency for assembly.
Brief description of the drawings
