Description
Technical field
The present invention relates to a kind of piston cooling nozzle body auxiliary machining device, particularly a kind of energy automatic turning 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 is heated from expanding excessive generation
Cylinder sticking, causes diesel engine major quality accident.
Adequately cooling machine oil, which is sprayed into, needs on predetermined piston base, 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.Because dowel hole and oil pipe hole are cold not 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 process and open up oil pipe hole process, opened after workpiece to be processed is carried out clamping by dowel hole process
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, which is transferred to, to be opened up oil pipe hole process and re-starts 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
In in base, base is stretched out in pull bar upper end, and pull bar upper end is incoming with the plug connector with grafting on the inside of piston and for plug connector
Through hole, described plug connector is latch, and latch is vertical with pull bar to be connected, and the two ends of latch can be plugged on the pin of piston respectively
Hole, described base upper end edge has the guide part with matching on the inside of piston skirt, and described base top is provided with elasticity
Support, bottom and the base of elastic support are connected, and the top of elastic support is free, and elastic support is matched with the medial surface of piston two.
The Chinese invention patent of Application No. 201310021492.8 disclosed in 2 days July in 2014, the name of its innovation and creation
Referred to as " piston rod deep hole boring grab ", it includes bottom plate, the parallel two V types support being apart arranged on bottom plate and pressed
Plate；Each V types support frame is constituted by the first support block and the second support block, one end of the first support block with second
One end docking of bracer constitutes V-type supporting and space；The top of first support block and the second support block is provided with locking screw holes, institute
State pressing plate to be detachably mounted to through lock-screw in the first support block and the second support block of two V-type support frames, the pressing plate
Formation cross-section grips space for the piston rod of triangle between two V-type support frames.
Above-mentioned patent application, is designed for piston rod is circular surface, however, the piston cooling spray of the application
Nozzle surface is plane, therefore above-mentioned patent application, can not still solve to need two procedures, multiple clamping, add cost of transportation,
The reduction of human cost and qualification rate, meanwhile, once can only one workpiece to be processed of clamping, cause production efficiency low, system
Cause high.
