The connecting ring (5) is fixed on the base (6). The measuring head is arranged on the connecting ring (5). An air passage (8) is arranged in the connecting ring (5). The air passage (8) is communicated with the measuring nozzle (3). The outlet of the nozzle (3) is arranged on the inner surface of the measuring head (4). The measuring head (4) is connected with an external electronic display. The thin-wall bearing part can be measured effectively, accurately and conveniently. The surface of the part under the measurement can not be scratched, and geometric shapes can not deform. The entire structure of the instrument is simple and the operation is convenient.
Description
Affiliated technical field
The utility model belongs to a kind of bearing outside diameter measurement mechanism, relates generally to a kind of middle-size and small-size thin-wall bearing ferrule external diameter air measuring device.
Background technology:
Present middle-size and small-size bearing ring wall thickness thinnest part has only 0.275mm, and thin-wall bearing ferrule size and form and position tolerance very easily produce distortion when adopting traditional mechanical gage to measure, and can't effectively measure; And (be generally 120～200g) influence, measured surface easily produces the survey trace, influences the measured workpiece surface quality, and this problem is an a great problem in bearing processing and even mechanical industry owing to ergometry.Particularly influence is particularly outstanding in the production run of military project bearing ring, and it has special technical requirement to the flexible bearing lasso: the internal diameter of control fabricated part and the mean value of external diameter.This still there is not at present effective measuring method.
Summary of the invention:
The purpose of this utility model provides a kind of thin-wall bearing ferrule external diameter air measuring device, and it can be effectively, accurately, easily the thin-wall bearing part is measured, and the surface of tested part does not scratch, and geometric configuration is indeformable.
The purpose of this utility model can adopt following technical scheme to realize: described measurement mechanism mainly comprises base, abutment ring, gaging nozzle and annular plug jet, plug jet is positioned on the abutment ring, gaging nozzle is set in the plug jet, be provided with annular air channel in the abutment ring, air flue is communicated with gaging nozzle, and plug jet is connected with the electronic console of outside.
Described gaging nozzle is eight, is distributed on a week of plug jet.
One joint that is connected with source of the gas is set on base, and joint is communicated with air flue in the abutment ring.One lasso guide post is set in the plug jet, is used for the axial location of tested lasso.
The utility model is that pneumatically is made medium according to hydrostatics and principle of hydrodynamics, and the variation of compressed air gap size compares measurement.The beneficial effects of the utility model: it has mainly solved middle-size and small-size thin-walled (particularly flexible bearing) bearing completed products lasso measuring outside diameter problem, has following characteristics:
(1) gauge head adopts 8 nozzles evenly to distribute, dynamometry little (＜20g), measured workpiece is indeformable, measured value is accurate.
(2) because gauge head does not directly contact with measured surface, avoided measured surface to produce and surveyed trace.
(3) owing to adopt non-cpntact measurement, gauge head does not does not wear and tear, the operating period limit for length.
(4) pneumatic gauging can be adopted higher enlargement factor, and personal error is little, the measuring accuracy height.
(5) gauge head can be connected with employing flexible pipe between the electronic console, can realize the telemeasurement operation.
(6) the instrument one-piece construction is simple, and is easy to operate.
Description of drawings:
Fig. 1 is the air measuring device synoptic diagram.
Among the figure: 1, tested lasso, 2, guide post, 3, gaging nozzle (8), 4, plug jet, 5, abutment ring, 6, base, 7, gas-tpe fitting, 8, air flue.
Embodiment
In conjunction with the accompanying drawings, specific embodiment of the utility model is described.
The utility model mainly comprises base 6, abutment ring 5, gaging nozzle 3 and annular gauge head 4, abutment ring 5 is fixed on the base, annular gauge head 4 is positioned on the abutment ring, gaging nozzle 3 has eight, circumferentially is distributed on the annular gauge head 4, and the outlet of gaging nozzle 3 is positioned at the inside surface of gauge head 4, be provided with annular air channel 8 in the abutment ring 6, eight gaging nozzles 3 are communicated with air flue respectively, and plug jet 4 becomes length value according to induction with stream pressure, by the electronic console demonstration measured value of outside.One lasso guide post 2 is set in abutment ring 5 and gauge head, and guide post 2 bottoms are positioned on the base 6.One gas-tpe fitting 7 is set on the base 6, and joint 7 outsides are connected with source of the gas by tracheae, and joint 7 inside are communicated with by air flue 8 in tracheae and the abutment ring 5.
During use, measure according to the following steps: before the measurement, standard component is transferred naturally along guide post 2, the standard component datum end face well contacts with the locating surface of guide post 2, make the tested place of tested lasso external diameter (avoiding chamfering) positive alignment gaging nozzle 3, adjust electronic console and make it show numerical value to zero-bit, preliminary work gets final product.
During measurement, tested lasso 1 is transferred naturally along guide post 2, tested lasso 1 datum end face well contacts with guide post 2 locating surfaces, and at this moment, the numerical value that shows on the electronic console is the external diameter physical size of tested lasso 1.
