Description
Technical field
The present invention relates to auto parts and components detection technique field, is a kind of cubing and detection method of bent axle fabrication hole position degree specifically.
Background technology
In the Crankshaft Machining process, bent axle fabrication hole position degree is one of project more rambunctious.Main manifestations is: 1, fabrication hole is as the angle positioning datum of correct grinding connecting rod neck, and the fabrication hole position degree determines whether the correct grinding connecting rod neck can Even Grinding.When the fabrication hole position degree was excessive, connecting rod neck cylindrical one side did not have process redundancy, caused connecting rod neck cylindrical shape can't guarantee that roughness does not reach technical requirement; When 2, the fabrication hole position degree was excessive, it is uneven that the cylindrical surplus appears in correct grinding connecting rod neck operation, and the grinding process medium plain emery wheel depth of cut is excessive, causes the damage of emery wheel; Connecting rod neck one side can't be ground to, and coarse journal surface forms the machine tool measuring instrument and damages.When 3, the fabrication hole position degree is excessive, even bent axle machines, also can descend owing to the depth of hardening inequality also can cause crankshaft fatigue strength.In view of above three reasons, it is very high that bent axle fabrication hole position degree control accuracy requires, and often need to be controlled at about Φ 0.1mm, far above the position degree requirement in the hole at other positions of bent axle.
At present both at home and abroad the bent axle fabrication hole detects and all adopts latch matching standard guide, detects latch and whether can determine whether overproof detection method of fabrication hole position degree by hole and insertion process hole.But below existing, this detection method covers end:
1, can't detect the actual numerical value of fabrication hole position degree.
The traditional handicraft hole position check tool can't detect the actual numerical value of fabrication hole position degree, can only whether can judge whether the fabrication hole position degree is overproof in the insertion process hole by latch; Simultaneously, in the acceptability limit, the quality of position degree can only judge by the tightness of latch in fabrication hole, and which side the fabrication hole position be partial to and can't detect by cubing, more can't make guidance to producing to adjust.
2, cubing is easy to wear, causes the accuracy of detection forfeiture
The precision of traditional handicraft hole position check tool mainly guarantees by the tolerance clearance of latch and standard guide.But because latch belonged to movingly with cooperating of standard guide, in actual use, latch and standard guide all can wear and tear, and through accumulating over a long period, the latch after the wearing and tearing and standard guide increase with the gap that cooperates loses accuracy of detection; Simultaneously, because latch has certain toughness, in the super much the same situation of fabrication hole position degree, still can be with latch insertion process hole by external force.Like this, finally cause testing result inaccurate.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present invention is to provide a kind of cubing and detection method that detects bent axle fabrication hole position degree, to detect easily and accurately bent axle fabrication hole position degree, realize readability and accuracy that bent axle fabrication hole position degree detects.
For achieving the above object, in the top and right top center pit that withstands on respectively two ends, the bent axle left and right sides in a left side of the present invention, it is characterized in that: the in-built latch that the bent axle fabrication hole is fixed on normal place that is useful on of standard guide; Gauge stand and cover plate are bolted, be provided with the groove that the V-arrangement slide block is slided up and down in the gauge stand, the V-arrangement slide block is contained in the groove, lock by cover plate, being equipped with between gauge stand and cover plate can be with spacing spring about the V-arrangement slide block is in cover plate, one end and the spring contact of V-arrangement slide block, the other end contacts with dial gauge, and clamping screw compresses expansion set makes dial gauge fixing on the cover board; The check and correction post is identical with the center height of standard guide, and the check and correction post is contained on the check and correction post base by screw, and check and correction post base through screws is connected with the cubing platform.
The detection method of detection bent axle fabrication hole position degree of the present invention, it is characterized in that: a left side is top to be fixed on horizontal level with the right side is top with bent axle, latch cooperates with the standard guide bent axle fabrication hole is fixed on normal place, dial gauge on the gauge stand by with the check and correction post to zero, the check and correction post is identical with the center height of standard guide; The gauge stand that check and correction is good with perpendicular to the direction of crankshaft center line near connecting rod neck, V-arrangement slide block and crank-shaft link neck are closely cooperated, in engagement process, the V-arrangement slide block slides up and down and drives the position degree that dial gauge shows connecting rod neck, and this indicating value is the upper-lower position degree of the relative connecting rod neck of bent axle fabrication hole.
The present invention compared with prior art can realize that bent axle fabrication hole position degree detects the in good time demonstration of data, and is simple in structure, use efficient and convenient, the testing result accuracy is high, can effectively instruct the position degree adjustment of bent axle fabrication hole, is conducive to control the position degree precision of bent axle fabrication hole.
