Description
Technical field
The present invention relates to auto parts and components detection technique field, the cubing of specifically a kind of position accuracy of crankshaft auxiliary hole and detection method.
Background technology
In Crankshaft Machining process, position accuracy of crankshaft auxiliary hole is one of project more rambunctious. Main manifestations is: 1, fabrication hole is as the angular positioning datum of fine grinding connecting rod neck, and fabrication hole position degree determines whether fine grinding connecting rod neck can Even Grinding. When fabrication hole position degree is excessive, connecting rod neck cylindrical side does not have allowance, causes that connecting rod neck outer circular shape cannot ensure, roughness does not reach technology requirement; 2, when fabrication hole position degree is excessive, fine grinding connecting rod neck operation occurs that cylindrical surplus is uneven, and the grinding process medium plain emery wheel depth of cut is excessive, causes the damage of emery wheel; Connecting rod neck side cannot be ground to, and machine tool measuring instrument is formed and damages by coarse journal surface. 3, when fabrication hole position degree is excessive, even if bent axle machines, decline also due to depth of hardening inequality will also result in crankshaft fatigue strength. In view of three above reason, position accuracy of crankshaft auxiliary hole control accuracy requires significantly high, generally requires controlling at �� about 0.1mm, far above the position degree requirement in the hole at other positions of bent axle.
Crankshaft auxiliary hole detection both at home and abroad at present all adopts latch matching standard guide, and whether detection latch can determine, by hole insertion process hole, the detection method whether fabrication hole position degree is overproof. But this detection method covers end below existing:
1, the actual numerical value of fabrication hole position degree cannot be detected.
Traditional handicraft hole position check tool cannot detect the actual numerical value of fabrication hole position degree, only by whether latch can judge that whether fabrication hole position degree is overproof in insertion process hole; Meanwhile, in acceptability limit, the quality of position degree judges only by latch tightness in fabrication hole, and which side fabrication hole position is partial to and cannot be detected by cubing, more cannot make guidance to producing adjustment.
2, cubing is easy to wear, causes accuracy of detection to lose
The precision of traditional handicraft hole position check tool ensures mainly by the fit clearance of latch Yu standard guide. But owing to latch belongs to dynamic cooperation with coordinating of standard guide, in actual use, latch and standard guide all can wear and tear, through accumulating over a long period, latch and standard guide after abrasion increase with the gap coordinated and lose accuracy of detection; Simultaneously as latch has certain toughness, in the super much the same situation of fabrication hole position degree, still can by latch insertion process hole by external force. So, testing result is ultimately resulted in inaccurate.
Summary of the invention
For overcoming the deficiencies in the prior art, the goal of the invention of the present invention is in that to provide a kind of cubing detecting position accuracy of crankshaft auxiliary hole and detection method, to detect position accuracy of crankshaft auxiliary hole easily and accurately, it is achieved the readability of position accuracy of crankshaft auxiliary hole detection and accuracy.
For achieving the above object, in the top centre bore withstanding on two ends, bent axle left and right respectively top with the right side in the left side of the present invention, it is characterised in that: standard guide is built with being used for being fixed on crankshaft auxiliary hole the latch of normal place; Gauge stand and cover plate are bolted, the groove that V-arrangement slide block can be made to slide up and down it is provided with in gauge stand, V-arrangement slide block is contained in groove, locked by cover plate, equipped with can by spring spacing up and down in cover plate for V-arrangement slide block between gauge stand and cover plate, one end of V-arrangement slide block and spring contact, the other end contacts with dial gauge, and clamping screw compresses expansion set makes dial gauge fixing on the cover board; Check and correction post is identical with the center height of standard guide, and check and correction post is contained on check and correction post base by screw, and check and correction post base through screws is connected with cubing platform.
The detection method of the detection position accuracy of crankshaft auxiliary hole of the present invention, it is characterized in that: left top top with the right side bent axle is fixed on horizontal level, latch coordinates with standard guide crankshaft auxiliary hole is fixed on normal place, dial gauge on gauge stand by with check and correction post to zero, check and correction post identical with the center height of standard guide; By the gauge stand proofreaded to be perpendicular to the direction of crankshaft center line near connecting rod neck, V-arrangement slide block and crank-shaft link neck is made to closely cooperate, in engagement process, V-arrangement slide block slides up and down the position degree driving dial gauge display connecting rod neck, and this indicating value is the upper-lower position degree of the relative connecting rod neck of crankshaft auxiliary hole.
The present invention is compared with prior art, it may be achieved the in good time display of position accuracy of crankshaft auxiliary hole detection data, simple in construction, use efficient and convenient, testing result accuracy is high, can effectively instruct the position degree adjustment of crankshaft auxiliary hole, is conducive to controlling the position degree precision of crankshaft auxiliary hole.
