Description
Technical field
The present invention relates to a kind of piston cooling nozzle body auxiliary machining device, particularly a kind of energy automatic loading and unloading machining piston
The fixture of cooling nozzles body opening.
Background technology
Piston cooling nozzle is one of strength member in diesel engine cooling system, and its effect is that cooling machine oil is accurate
Really, the predetermined piston base of in good time penetrating, is sufficiently cooled to piston, prevents piston to be heated and expands excessive generation
Cylinder sticking, causes diesel engine major quality accident.
Adequately cooling machine oil is sprayed into into predetermined piston base, needed on piston cooling nozzle body while offering positioning
There is relative position degree requirement between pin-and-hole, oil pipe hole and nozzle body mesopore, and three holes.Piston cooling nozzle body in blanking,
Nozzle body mesopore has been come with, therefore need to only open up dowel hole and oil pipe hole.Due to dowel hole and oil pipe hole it is not cold in piston
But the same surface of nozzle body, such as dowel hole and the same locating and machining plane of injector body mesopore, and oil pipe hole then exists
The top surface of piston cooling nozzle body, therefore prior art need to be provided with two procedures in locating and machining pin-and-hole and oil pipe hole,
Respectively open up dowel hole operation and open up oil pipe hole operation, open after workpiece to be processed is carried out clamping by dowel hole operation
If dowel hole, and can only once fix a workpiece to be processed, then will offer again the workpiece to be processed of dowel hole from
Original-pack folder workpiece is transferred to and opens up oil pipe hole operation and re-start clamping, completes opening up for oil pipe hole, and now, one
It is secondary also to grip a workpiece to be processed.
The Chinese invention patent of Application No. 201110144359.2 disclosed in 19 days October in 2011, its innovation and creation
Entitled " a kind of positioning tooling fixture of piston ", it includes cylindrical base and in shaft-like pull bar, pull bar lower end position
