The utility model discloses a hydro -cylinder for triple -cropping that bent axle spot facing work was used, structural design is equitable, and convenient operation can reduce the resistance to cutting, improves the stability of processing to can sparingly process time of preparation, improvement production efficiency, and can improve the stability of processing and the life of extension processing cutter, process the bent axle hole high quality that obtains.

Description

A kind of three action oil cylinders of crankshaft hole processing
Technical field
The utility model relates to the process equipment of crankshaft hole in a kind of building-block machine, is specifically related to three action oil cylinders of a kind of crankshaft hole processing, belongs to Machining Technology field.
Background technology
Traditional crankshaft hole processing method is: workpiece pushes away loads onto material, location clamping; Boring head advances processing.This roughing mode can produce very large resistance to cutting, and boring bar is out of shape, and produces cutting vibration, has a strong impact on the crudy of crankshaft hole.Draw boring to process and can reduce resistance to cutting, increase substantially the crudy of crankshaft hole.But load onto the crankshaft hole of bearing shell, boring bar can not be stretched, can only after fill cutter, bring great inconvenience to the adjustment of cutter, the time also can increase greatly simultaneously, have a strong impact on the working (machining) efficiency of product.
Therefore, necessary design on the basis of prior art researches and develops a kind of reasonable in design, can reduce resistance to cutting, improve the stability of processing, and can improve three action oil cylinders of the crankshaft hole processing of the crudy of crankshaft hole.
Summary of the invention
Goal of the invention: the purpose of this utility model is to solve the deficiencies in the prior art, a kind of reasonable in design is provided, easy to operate, resistance to cutting can be reduced, improve the stability of processing, and can the leading time be saved, and enhance productivity, three action oil cylinders of the crankshaft hole processing that the crankshaft hole quality that processing obtains is high.
Technical scheme: in order to realize above object, the technical scheme that the utility model is taked is:
Three action oil cylinders of crankshaft hole processing, it comprises left cylinder body, is arranged on the left piston in left cylinder body, is arranged on the valve piston in left piston, the small piston rod be connected with valve piston; Described left piston docks with main piston rod activity, and the main piston rod other end docks with right piston activity, and right piston is arranged in right cylinder body;
Described small piston rod can pass left piston and be connected with main piston rod.
Preferably, three action oil cylinders of above-described crankshaft hole processing, the area of described left piston is greater than the area of right piston.
Preferably, three action oil cylinders of above-described crankshaft hole processing, the area of described right piston is greater than the area of valve piston.
Preferably, three action oil cylinders of above-described crankshaft hole processing, described main piston rod are processed with tooth bar, the meshing connection of rack and pinion.
Preferably, three action oil cylinders of above-described crankshaft hole processing, described gear is connected with vertical tooth rack, and vertical tooth rack is connected with bracket.
Three action oil cylinders of the crankshaft hole processing that the utility model provides, as follows in crankshaft hole processing specific works process:
First make right side oil cylinder and left side oil cylinder oil-feed simultaneously (left side oil cylinder is in limit on the right-right-hand limit position), the pressure due to hydraulic oil is equal and the piston area in left side large, therefore the large piston in left side can not move; But much little on the right side of the area ratio of the valve piston in left side, therefore much larger than valve piston of the pressure on right side, all main piston rods can push small piston rod and move a bit of stroke to the left and (main piston rod is processed with tooth bar, rack drives gear, gear drives vertical tooth rack again, rack drives bracket moves down), thus realize cutter relieving action.Now boring bar is arrived by crankshaft hole and draws boring position.
Make right side oil cylinder continue oil-feed, left side oil cylinder is fuel-displaced, and right hand piston promotes main piston rod to be continued to move to left, and drives engine cylinder-body to arrive Working position (realize action and step is the same).
Boring bar draws boring machining crankshafts hole to completing; Then left side oil cylinder oil inlet, the also oil-feed of right side oil cylinder, the area due to left piston is greater than the area of right piston, therefore left piston pushes main piston rod moves right, and comes allow cutter position.(area of valve piston is less than right hand piston, and when pressure is equal, valve piston can not move right).Main shaft orientation, guide pin bushing is located, and main shaft stops, and boring bar exits cylinder body to initial position.
Left side oil cylinder continues oil-feed, right side oil cylinder fuel-displaced (pressure is disregarded), the large piston in left side reaches extreme position, therefore valve piston promotes move right a bit of stroke and workpiece of main piston rod lifts (realize action and step is the same), manually releases.Complete the processing of crankshaft hole.
Beneficial effect: compared to the prior art three action oil cylinders of the crankshaft hole processing that the utility model provides have the following advantages:
Three action oil cylinders of crankshaft hole processing of the present utility model, reasonable in design, easy to operate, resistance to cutting can be reduced, improve the stability of processing, and can the leading time be saved, enhance productivity, and the stability of processing can be improved and extend the service life of process tool, the crankshaft hole quality that processing obtains is high.
Accompanying drawing explanation
The structural representation of three action oil cylinders that accompanying drawing 1 is processed for crankshaft hole.
Detailed description of the invention:
Below in conjunction with specific embodiment, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
