Description
Technical field
The utility model relates to Manufacturing Technology for Automotive Parts field, specifically a kind of crankshaft counter balance dip plane low spot turning radius cubing that detects.
Background technology
Bent axle is as the main parts size of High Rotation Speed in engine, consider engine cylinder-body inner structure, for ensureing that bent axle runs well in cylinder body, as shown in Figure 8, Figure 9, the counterbalance weight 9 of bent axle 10 has correspondingly increased by two dip plane, interferes avoiding with housing structure.1., crankshaft counter balance and cylinder body interference in Crankshaft Machining, if balance block structure can not meet the demands, there is very large potential safety hazard:, cause engine to run well; 2., affect crankshaft dynamic balance, cause engine bearing inordinate wear, vibration large.
In the actual process of bent axle, except ensureing the angle on counterbalance weight two inclined-planes, also need the low spot turning radius 1 that ensures two inclined-planes to meet technical requirement with the turning radius 27, traditional detection method is: on platform, support main bearing journal, according to the turning radius requirement of counterbalance weight dip plane, on bent axle, rule with height gauge, observe scribing position and actual process position whether one show judge whether qualified.This detection method weak point is:
1., after bent axle operation machines, bent axle need be transported to position of platform, bent axle is lifted on platform, after bent axle has detected, returns to this operation again, this process wastes time and energy, and production efficiency is low.
2., platform inspection needs to support bent axle two king journals with adjustable v-type piece, detects two ends king journal height with band table height gauge, adjusts V-block and guarantees bent axle level, measures king journal center line height; According to king journal diameter and the low spot requirement of counterbalance weight inclined-plane, adjust height gauge, mark theoretical inclined-plane low dot location and contrast with actual Working position, detect successively all counterbalance weights inclined-plane size.If this testing result is defective, after lathe adjustment processing, the more above-mentioned work of rechecking, detecting approximately 15 minutes bent axle used times, detection efficiency is low, wastes time and energy.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is to provide a kind of crankshaft counter balance dip plane low spot turning radius cubing that detects, to realize the object at this operation fast detecting crankshaft counter balance dip plane low spot turning radius.
For achieving the above object, the utility model comprises cubing one, cubing two, described cubing one comprises cubing top arc surface one, cubing top arc surface two, cubing end face one and cubing bottom arc surface one, between cubing top arc surface one and cubing top arc surface two, form groove one, cubing top arc surface one and the Upper-lower Limit value of cubing top arc surface two as the crankshaft counter balance inclined-plane low spot turning radius one, between form go-no go gauge;
Described cubing two comprises cubing top arc surface three, cubing top arc surface four, cubing end face two, cubing bottom arc surface two, between cubing top arc surface three and cubing top arc surface four, form groove two, cubing top arc surface three and the Upper-lower Limit value of cubing top arc surface four as the crankshaft counter balance inclined-plane low spot turning radius two, between form go-no go gauge.
Described cubing one is fitted with the laminating of axle king journal cylindrical, cubing end face one, cubing end face two and crankshaft counter balance end face with cubing bottom arc surface one, the cubing bottom arc surface two of cubing two.
The utility model makes full use of main bearing journal cylindrical and crankshaft counter balance end face location, the bottom of groove and top are as the upper and lower deviate of the counterbalance weight inclined-plane low spot turning radius, form go-no go gauge, when detection the turning radius one with the turning radius two if in cubing groove, be qualified.
The utility model, compared with traditional detection method, can be realized at this operation fast detecting crankshaft counter balance dip plane low spot turning radius.Structure and simple to operate, detects a bent axle and only needs 30 seconds, can effectively improve detection efficiency, alleviates labor intensity of operating staff.
