Abstract
The utility model relates to a fit clearance pneumatic measuring instrument and belongs to the technical field of measuring devices. The fit clearance pneumatic measuring instrument can directly carry out fit clearance measurement between an axle, a piston, a bent axle and the like and a hole. An inner diameter pneumatic measuring head (1) and an outer diameter pneumatic measuring head (2) are connected with a display electric case (3) after a gas connection air channel (5) is combined, and are supplied with air through an external steady pressure air source (4). By means of the fit clearance pneumatic measuring instrument, the technology that fit clearance is guaranteed indirectly by respectively measuring outer diameter size of the axle, the piston, the bent axle and the like and an inner diameter size of the hole is replaced by directly measuring an actual size of the fit clearance, and therefore an assembly effect is guaranteed. By means of the fit clearance pneumatic measuring instrument, new devices are not provided, only pneumatic measuring heads measuring the inner diameter and the outer diameter are recombined and connected. Therefore, the fit clearance pneumatic measuring instrument is simple and practicable in structure.
Description
Technical field:
The utility model relates to the tolerance clearance pneumatic gauging instrument in a kind of axle, piston, bent axle etc. and hole, can directly carry out clearance measurement, belongs to the surveying instrument technical field.
Background technology:
At present, the most advanced pneumatic measuring instrument by plug jet, up and down calibrating device, show that electronic box 3 three parts form a cover and use, the different measuring workpiece needs the different plug jet (like Fig. 1 internal diameter pneumatic measuring instrument, Fig. 2 external measuring instrument) of use.And in most manufacturing enterprises, the tolerance clearance in axle, piston, bent axle etc. and hole is unusual important techniques index.Owing to there is not directly to measure the surveying instrument of this index, can only separate provision and the external diameter and the hole internal diameter of measurement axis, piston, bent axle etc.And often owing to different measuring system or measurement environment, actual tolerance clearance can not satisfy the requirement of regulation, makes the effect of actual product reduce.
Summary of the invention:
In order to separate the directly problem of measurement axis, piston, bent axle etc. and hole tolerance clearance; The utility model provides a kind of pneumatic measuring instrument; This measuring instrument not only possesses the noncontact of traditional, pneumatic measuring instrument, high-precision advantage; More can directly measure the tolerance clearance size, improve the overall efficacy of efficiency of assembling and product.
The utility model solves the technical scheme that its technical matters adopted: internal diameter plug jet 1 is connected with demonstration electronic box 3 with after external diameter plug jet 2 is connected gas circuit 5 through merging gas again, and by outside pressure-stabilized air source 4 air feed.
Show that electronic box is exactly the gas-tight clearance pressure variation through plug jet and surface of the work; And then be converted into the unit that electric signal is measured demonstration; And this utility model just changes the connected mode of plug jet; Show that electronic box experiences axle, piston, bent axle etc. and external diameter plug jet simultaneously, the gas-tight clearance pressure of hole and internal diameter plug jet, thus directly measure the size of tolerance clearance.At first show the electronic box lower limit as the little value calibration of tolerance clearance during use with the little calibrating device of internal diameter, the big calibrating device of external diameter school; Re-use the big calibrating device of internal diameter, the little calibrating device of external diameter and show the upper limit of electronic box, just can normally measure as the big value calibration of tolerance clearance.
The beneficial effect of the utility model is, comes to guarantee indirectly tolerance clearances by outside dimension such as measurement axis, piston, bent axle respectively and hole internal diameter size, changes the actual size that directly carries out tolerance clearance into, guarantees the assembling effect.Do not increase new device, only reconfigure the plug jet of outside diameter measuring in connecting, simple for structure.
Description of drawings:
Fig. 1: the structural representation of internal diameter pneumatic measuring instrument;
Fig. 2: the structural representation of external diameter pneumatic measuring instrument;
Fig. 3: tolerance clearance pneumatic measuring instrument structural representation in the utility model;
Among the figure: 1, internal diameter plug jet, 2, the external diameter plug jet, 3, show electronic box, 4, outside pressure-stabilized air source, 5, merge gas and connect gas circuit.
Embodiment:
Be further described for the present invention below in conjunction with accompanying drawing and embodiment.
Internal diameter plug jet 1 and external diameter plug jet 2 are connected with demonstration electronic box 3 through after merging gas and being connected gas circuit 5 again among Fig. 1, and by outside pressure-stabilized air source 4 air feed.At first show the electronic box lower limit as the little value calibration of tolerance clearance during use with the little calibrating device of internal diameter, the big calibrating device of external diameter school; Re-use the big calibrating device of internal diameter, the little calibrating device of external diameter show electronic box as the big value calibration of tolerance clearance the upper limit; While puts the Parapsida workpiece at internal diameter plug jet 1 again, external diameter plug jet 2 is put shaft-like workpiece, shows that electronic box 3 measurement result at this moment is the tolerance clearance of these two workpiece.
Claims (1)
1. tolerance clearance pneumatic measuring instrument is characterized in that: internal diameter plug jet (1) and external diameter plug jet (2) are connected with demonstration electronic box (3) through after merging gas and being connected gas circuit (5) again, and by outside pressure-stabilized air source (4) air feed.
