The measuring process of this quasi-instrument is carried out in two steps, and the first step is for measuring zero: sensor is placed measure the anvil end face in the heart, the standard of packing into earlier ring adds measurement load, carries out static measurement, draws an instantaneous value; Second step was actual measurement: the measured bearing of packing into replaces the standard ring, adds measurement load, and the rotary air main shaft carries out kinetic measurement, records series of values, gets its mean value.The difference of the instantaneous value that this mean value and the first step record is measurement result.
Owing to adopted more component parts in the measuring process, as measure anvil, locating ring, plug, standard ring, the processing of these parts itself and the cooperation of adjacent component all can produce certain error, conclusion is got up, and mainly contains following error: the verticality of air spindle end face relative theory axis; The depth of parallelism of the upper and lower end face of locating ring own; The depth of parallelism to the upper and lower end face of zero standard lead ring own; Measure the depth of parallelism of the upper and lower end face of anvil own; Measure the error that cooperates generation of anvil and standard ring; The verticality of worktable relative measurement axis; The error of sum of errors electric part that also has the not parallel generation of the axial line of displacement transducer and theoretical axis in addition.
By the error analysis of front as can be known, owing to only surveyed an instantaneous value when measuring zero, measured value subsequently all is to be that benchmark draws with this instantaneous value, and this instantaneous value is at random, must bring error to measured value, this error can be embodied in the repeatedly measurement to same bearing.
Summary of the invention
The purpose of this utility model provides a kind of bearing measuring instrument for projection, and this measuring instrument has been eliminated the traditional measurement instrument can only record the measuring system error that an instantaneous value brings owing to measuring zero, has improved the measuring accuracy of measuring instrument.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of bearing measuring instrument for projection is made up of machinery part, pneumatic control part and electric part.Machinery partly comprises the axis that the lower end is connected with elevating mechanism, and air spindle is housed on the axis, and the mandrel that can match with standard ring or bearing to be measured is housed on the air spindle; Have center pit on the worktable, go up coaxial connection of ring with the air supporting thrust bearing the worktable lower surface, and the following ring of air supporting thrust bearing is affixed with the lower end that is enclosed within the abutment ring in the worktable center pit, and baffle ring is equipped with in the upper end of abutment ring; Air spindle and mandrel, air supporting thrust bearing, worktable center pit are coaxial; Displacement transducer passes the endoporus of abutment ring, and its lower end contacts with the interior ring end face of standard ring or bearing to be measured, and its upper end is connected with electrical appliance part or has refilled indicating gauge in the displacement transducer upper end; Pneumatic part is connected with air supporting thrust bearing, air spindle respectively.
Said elevating mechanism is made up of cylinder, piston, and the axis lower end is connected with piston, and pneumatic part is connected with cylinder.
The useful effect that the utlity model has is: by increase an air supporting thrust bearing in the worktable lower end, can record a series of values when measuring and get its average zero, eliminate the traditional measurement instrument owing to can only record the measuring system error that an instantaneous value brings during to zero measurement, improved the measuring accuracy of measuring instrument.
Description of drawings

In the accompanying drawing: 1. indicating gauge, 2. displacement transducer, 3. baffle ring, 4. worktable, 5. abutment ring, 6. air spindle, 7. mandrel, 8. standard ring, 9. air supporting thrust bearing, 10. sensor contact, 11. bearings to be measured, 12. axis, 13. cylinders, 14. pistons.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in drawings, the utility model is made up of machinery part, pneumatic control part and electric part.Machinery partly comprises the lower end and is contained in the axis 12 that cylinder 13 inner carriers 14 are connected that air spindle 6 is equipped with in axis 12 upper ends, and the mandrel 7 that can match with standard ring 8 or bearing to be measured 11 is equipped with in air spindle 6 upper ends; Have center pit on the worktable 4, go up coaxial connection of ring with air supporting thrust bearing 9 worktable 4 lower surfaces, and the following ring of air supporting thrust bearing 9 is affixed with the lower end that is enclosed within the abutment ring 5 in worktable 4 center pits, and baffle ring 3 is equipped with in the upper end of abutment ring 5; Air spindle 6 and mandrel 7, air supporting thrust bearing 9, worktable 4 center pits are coaxial; Displacement transducer 2 passes the endoporus of abutment ring 5, and its lower end contacts with the interior ring end face of standard ring 8 or bearing to be measured 11, and its upper end partly is connected with electrical equipment or has refilled indicating gauge in displacement transducer 2 upper ends; Pneumatic part is connected with air supporting thrust bearing 9, air spindle 6, cylinder 13 respectively.
The concrete course of work is as follows:
As shown in the drawing, when carrying out measuring, standard ring 8 is packed in the mandrel 7, rely on mandrel 7 ring 8 shaft core positions that settle the standard zero.On air spindle 6, apply measurement load, make it to rise, push standard ring 8 the thrust air-bearing 9 of top to, withstand air supporting thrust bearing 9 up to standard ring 8.Then, the contact 10 of displacement transducer 2 is placed standard ring 8 surfaces (near thrust air-bearing 9 inboards, top), sensor indicating gauge 1 is adjusted to zero-bit, rotary air main shaft 6 can record one group of data, gets its average; Unloading enters the actual measurement stage then.
After removal was applied to load on the air spindle, air spindle 6 and mandrel 7 and standard ring 8 placed on it slowly descended together, and standard ring 8 has been broken away from and the contacting of thrust air-bearing 9, and took out standard ring 8;
Bearing 11 to be measured is enclosed within on the mandrel 7, on air spindle 6, apply measurement load, make it to rise, bearing 11 to be measured is pushed to the thrust air-bearing 9 at top, withstand thrust air-bearing 9 up to bearing 11 to be measured, bearing 11 inner rings to be measured withstand sensor contact 10 and produce one section axial displacement.Then, rotary air main shaft 6 can record one group of data, gets its average.
