Description
Technical field
The utility model relates to a kind of pick-up unit, the portable detector of the adjacent shelves jitter values of especially a kind of shaft forgings.
Background technology
Along with country improves the upgrading of engine emission standard, bent axle, camshaft improve constantly the control overflow in the requirement of adjacent shelves jitter values and manufacture process as crucial, vitals, therefore, in process control and part parts testing process, strong actual demand is had.Bent axle, camshaft are because length-diameter ratio is large, weight is large, its adjacent shelves jitter values cannot be undertaken simulating (when measuring the axle journal on both sides by platform+V-block, due to workpiece deviation of gravity center carrying plane, workpiece can topple), current detection can only adopt the Adcole composite measurement machine of imported from America to carry out.But there is following shortcoming in this detection means:
1) cost of investment is large: the checkout equipment of generally acknowledging at present only has U.S. Adcole composite measurement machine, and its equipment investment is huge, reaches more than 200 ten thousand yuan, and this directly has influence on the universal of this equipment;
2) measure efficiency low: Adcole is measured by the mode of demixing scan, then by calculating data, therefore, measure efficiency comparison low, for six-cylinder crankshaft (long about 0.9m), Measuring Time was more than 20 minutes.
3) measurement is very inconvenient: must deliver to special measuring chamber, clean center pit, measured surface, and installs by manually accurately going up machine, clamp;
4) can not Site Detection be realized: in existing production run, large batch of tractor crankshaft, cannot realize instant, on-the-spot, detect fast.
Therefore, the portable detector of adjacent shelves jitter values, has strong actual demand in process control and part parts testing process.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides the portable detector of the adjacent shelves jitter values of a kind of shaft forgings, can the adjacent shelves jitter values of quick, high-precision measurement bent axle.
According to the technical scheme that the utility model provides, a portable detector for the adjacent shelves jitter values of shaft forgings, comprises test rod, it is characterized in that: the two ends of described test rod are respectively equipped with V-block, the bottom of V-block is provided with V-type groove, and the madial wall of V-type groove is respectively equipped with back-up block; The middle part of test rod is provided with through hole, is provided with spacer in through hole, installs clock gauge in spacer.
On described test rod, the radial direction of through hole is provided with lock-screw, and lock-screw holds out against spacer.
The portable detector of shaft forgings described in the utility model adjacent shelves jitter values utilizes and connects the benchmark simulation that all-in-one-piece " double V-shaped " achieves adjacent axle journal, clock gauge is utilized to achieve measurement and the digital independent of the adjacent shelves jitter values of tested axle journal, achieve the portable type measuring of adjacent shelves jitter values, can realize at the scene of production run, storehouse measuring; Measuring accuracy can meet design accuracy (usual adjacent shelves design accuracy is 0.03 ~ 0.04, with the measurement of comparison of Adcole, error≤0.005, meets measuring accuracy completely and requires); With regard to the measurement of adjacent shelves jitter values, its efficiency is more than 30 times of Adcole composite measurement machine; Compared with the investment of Adcole composite measurement machine more than 2,000,000, the cost of investment of this device is less than 10,000 yuan.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the side view of Fig. 1.
Embodiment
Below in conjunction with concrete accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2: the portable detector of the adjacent shelves jitter values of described shaft forgings comprises lock-screw 1, spacer 2, V-block 3, back-up block 4, measured workpiece 5, test rod 6 etc.
As shown in Figure 1, the utility model comprises test rod 6, and the two ends of test rod 6 are respectively equipped with V-block 3, and the bottom of V-block 3 is provided with V-type groove, the madial wall of V-type groove is respectively equipped with back-up block 4; The middle part of test rod 6 is provided with through hole, is provided with spacer 2 in through hole, installs clock gauge in spacer 2; On test rod 6, the radial direction of through hole is provided with lock-screw 1, and lock-screw 1 holds out against spacer 2.
Sounding rod 6 and V-block 3 are made up of steel, and mainly provide the installation matrix of measurement mechanism, keep stability and the consistance of structural rigidity, for a long time holding structure when measuring, physical dimension must ensure when measuring revolution and workpiece does not produce interference;
Back-up block 4 is made up of materials such as hard nylon, brass, problems such as avoiding the polished surface of measured workpiece 5 to damage in measuring process, scratch, collide with, its one side is fitted with the V-type groove madial wall of V-block 3, structurally possesses V-type feature, another side and measured workpiece 5 cylindrical are fitted, and simulate adjacent shelves measuring basis;
Lock-screw 1 and spacer 2 are made up of steel, provide horizontal pressure under threaded function during lock-screw 1 rotational lock spacer 2, reliably fix clock gauge, do not have influence on moving up and down of clock gauge measuring head again.
Principle of work of the present utility model and the course of work: as shown in Figure 2, on the V-block that measured workpiece 5 can be positioned over platform or reversing frame, (platform, reversing frame do not participate in detecting, only in order to measure conveniently), can spread out on the ground and put, workpiece does not have the requirement of level, vertical, rotating accuracy yet;
Clean detected workpiece 5 and benchmark axle journal, the V-type groove on V-block 3 and adjacent shelves cylindrical are fitted respectively, the measuring head of clock gauge contacts with measured workpiece 5 journal surface;
Rotate this measurement mechanism one week or measurement mechanism motionless, workpiece rotate one week;
Read clock gauge at the degree reading of rotation in one week, maximal value deducts minimum value and is jitter values.The measurement that the utility model also can utilize pneumatic, inductance, resistance to carry out beating and reading; V-type spacing is adjustable, meets different series tractor crankshaft.
