Abstract
The utility model provides a portable test crankshaft oil hole position degree examine utensil for short -term test crankshaft oil hole position. Go up the semicircle and examine piece one side lower part for arc structure no. 1, its arch section no. 1 and camshaft connecting rod neck surfaces to mate, going up the semicircle and examining an opposite side and examine the piece with semicircle down and is connected, lower semicircle is examined a lower part and is arc structure no. 2, its arch section no. 2 and main bearing journal surfaces to mate, the space for placing crankshaft counter balance between the piece is examined to upper and lower semicircle, upper and lower semicircle is examined a centre -to -centre spacing and is bent axle slewing radius. To go up the semicircle and examine piece and camshaft connecting rod neck cooperation, the plane in groove is at the projection line and the center coincidence of camshaft connecting rod neck oilhole of horizontal direction it on, and piece and main bearing journal cooperation are examined to lower semicircle, and its lower extreme horizontal plane and the coincidence of trunnion oil hole center line can confirm through the perusal whether qualified connecting rod neck oilhole and trunnion oilhole position be. The utility model discloses can realize quick, the accurate detection of crankshaft oil hole, simple structure, small and exquisite, but anytime and anywhere detects the crankshaft oil hole.
Description
Technical field
The utility model relates to Manufacturing Technology for Automotive Parts field, specifically a kind of portable dedicated cubing for detecting crankshaft oil hole position degree.
Background technology
Bent axle as the main parts size of engine, can High Rotation Speed mainly because can good lubrication be kept between bent axle and bearing shell.And the effect of crankshaft oil hole is communicated with the oil circuit between bent axle and bearing shell, keep the smooth and easy surface being arrived all bearing shells by oilhole of lubricating oil that high-pressure oil pump produces, form oil film.If the position degree of crankshaft oil hole cannot meet the demands, potential safety hazard is huge, and engine oil path can be caused obstructed, causes the even bent axle locking of engine Bearing score, tile kilning, cannot operate.So the position degree of crankshaft oil hole is one of important parameter that must ensure in the fabrication process.
In the batch production of bent axle, the position degree of crankshaft oil hole detects the mode often adopting marking on slab.Need bent axle level correction in testing process, then use height gauge beats the peak that table finds crankshaft crank repeatedly.Then, by the altitude conversion of complexity, obtain oilhole place height, then determine whether oil-hole location degree meets the requirements by height gauge line.There is very large drawback in this detection mode:
1, in inspection, look for crankshaft crank peak to need repeatedly to play table repeatedly, altitude conversion is intricate, checkability is low, often check the position degree of one group of oilhole to need five-minute period, a six-cylinder crankshaft has six groups of oilholes, and a tractor crankshaft completes and needs about half an hour.This just makes the sampling observation frequency of bent axle can not be too high, adds the underproof risk of product.
2, the nuance of different reviewer in detection gimmick can cause testing result inconsistent, and Repeatability and Reproducibility is all very poor, is very easy to the situation occurring erroneous judgement in actual testing process.
3, the cubing of marking on slab is bulky, and at least need the floor area of two square metres, place to use is fixed, and cannot meet the needs detected whenever and wherever possible.
4, the mode of marking on slab needs to provide the cubings such as macrotype platform, V-type support, height gauge, and a set of cubing configuration is costly.
Summary of the invention
For overcoming the deficiencies in the prior art, goal of the invention of the present utility model is the cubing providing a kind of portable inspectiont crankshaft oil hole position degree, to realize the object of carrying out fast crankshaft oil hole position degree, accurately detecting.
For achieving the above object, the bottom of upper semi-circle inspection block side of the present utility model is arcuate structure one, arch section one and the crank-shaft link neck surface engagement of its arcuate structure one; The opposite side of upper semi-circle inspection block is examined block by screw and lower half circle and is connected, and the bottom of lower half circle inspection block is arcuate structure two, arch section two and the main bearing journal surface engagement of its arcuate structure two; Upper semi-circle inspection block and lower half circle are examined between block as placing the space of crankshaft counter balance; The centre distance that the center of upper semi-circle inspection block and lower half circle examine block is the turning radius of bent axle; Upper semi-circle inspection block has groove, and the plane of groove projection line in the horizontal direction and crank-shaft link neck oilhole center superposition, lower half circle is examined block lower end surface level and is overlapped with the oilhole center line of king journal, and crankshaft oil hole position is qualified.
Described upper semi-circle inspection block and lower half circle examine block respectively with for regulate upper semi-circle to examine elongated hole that block and lower half circle examine block centre distance.
The top of described upper semi-circle inspection block is with handle.
After upper semi-circle of the present utility model inspection block coordinates with crank-shaft link neck, upper semi-circle examines plane that block is slotted projection line in the horizontal direction and crank-shaft link neck oilhole center superposition.After lower half circle inspection block coordinates with main bearing journal, lower half circle inspection block lower end surface level overlaps with king journal oilhole center line.By plane projection line in the horizontal direction and the registration at connecting rod neck oilhole center of visual inspection upper semi-circle inspection block groove, whether the position just detecting connecting rod neck oilhole is qualified; Observe the registration of lower half circle inspection block lower end surface level and king journal oilhole center line, whether qualifiedly just can detect the position of determining king journal oilhole.
The utility model compared with prior art, can realize the quick detection of crankshaft oil hole, and testing result is accurate, not by the impact of operating personnel's gimmick.Structure is simple, and low-profile, can detect crankshaft oil hole whenever and wherever possible.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the bottom of upper semi-circle inspection block 1 side is arcuate structure one, arch section one and crank-shaft link neck 5 surface engagement of its arcuate structure one; The opposite side of upper semi-circle inspection block 1 is examined block 3 by screw 2 and lower half circle and is connected, and the bottom of lower half circle inspection block 3 is arcuate structure two, arch section two and main bearing journal 4 surface engagement of its arcuate structure two; Upper semi-circle inspection block 1 and lower half circle are examined between block 3 as placing the space of crankshaft counter balance; The centre distance that center 1 and the lower half circle of upper semi-circle inspection block examine block 3 is the turning radius of bent axle; Described upper semi-circle inspection block 1 and lower half circle examines block 3 respectively with for regulate upper semi-circle to examine elongated hole that block 1 and lower half circle examine block 3 centre distance; The top of described upper semi-circle inspection block 1 is with handle 8.
During use, upper semi-circle is examined after block 1 is pressed in crank-shaft link neck 5 is mated, the plane 6 of slotting projection line 9 in the horizontal direction and crank-shaft link neck 5 oilhole center superposition on upper semi-circle inspection block 1, after lower half circle inspection block 3 is pressed in and main bearing journal 4 is mated, lower half circle inspection block 3 lower end surface level 7 overlaps with the oilhole center line of king journal 4, just can determine that whether the position of connecting rod neck oilhole and king journal oilhole is qualified by visual inspection, realize quick and precisely detecting.
