Compared with the prior art, the utility model has the beneficial effect that the special testing equipment has simple structure, convenient and reliable use, and simple manufacturing process. The precision of the special testing equipment can reach 0.001 mm, which completely can reach the measuring requirement of a precise part.
Description
Technical field
The utility model belongs to the tool field of testing, and particularly measures the axial relative size of multidiameter and tests the tool field.
Background technology
When measuring the axial relative size of multidiameter, mainly adopt measurers such as vernier caliper, height gauge to measure, shortcoming is that efficient is low, precision is not high in the past.In order to enhance productivity, guarantee machining precision, need a kind of special use to test tool and improve metering system.
To propose especially be grinding similar as accompanying drawing 1 part the M face and during the N face, want to guarantee that axial relative size precision must often measure.When utilizing this special use to test the tool measurement, needn't pull down anchor clamps (heart chuck) and can directly measure, reduce work step, improve efficient.
The utility model content
The utility model is simple in structure, and is easy to use, reliable, and manufacturing process is also very simple.Its precision can reach 0.001mm, can reach the measurement requirement of precision component fully.
The axial relative size special measurement of multidiameter is tested tool, by 1, test axle, and 2, measuring unit, 3, the measurement and positioning axle, 5, spring, 7, copper sheathing, 8, clock gauge forms; Wherein, copper sheathing 7 is enclosed within the top that together is fixed on measuring unit 2 on the gauge head bar of clock gauge 8, and an end of measurement and positioning axle 3 jacking springs 5 together is installed in the endoporus of measuring unit 2, tests the end face that axle 1 inserts measuring unit 2 and withstands measurement and positioning axle 3.
On the described measurement and positioning axle 3 ring groove is arranged, a screw is arranged on the measuring unit 2, stop screw 4 screws in these screws and withstands on the ring groove on the measurement and positioning axle 3, plays position-limiting action.
Described measuring unit 2 is provided with through hole, and flush end holding screw 6 penetrates this screw copper sheathing 7 and clock gauge 8 are fixed together.
For measuring unit 2, measurement and positioning axle 3 and test the axle 1 three part requirement be the high-carbon steel material, carry out Quenching Treatment, hardness HRC58-63 before the finishing.The cylindrical of the endoporus of measuring unit 2 and the verticality of large end face thereof, measurement and positioning axle and the verticality of large end face thereof, the little cylindrical of testing axle 1 and the verticality of both ends of the surface thereof all require in the 0.01mm scope, and the endoporus of measuring unit 2 will be slidingly matched with the cylindrical of measurement and positioning axle, the little cylindrical of testing axle 1 and the cylindrical of tested part, the axial relative size of testing the both ends of the surface of axle 1 little cylindrical is processed into the middle poor of the axial relative size of tested part, uses zero in order to clock gauge.
Description of drawings
Fig. 1 is the tested part synoptic diagram.
Fig. 2 is the utility model structural representation, wherein 1, test axle, and 2, measuring unit, 3, the measurement and positioning axle, 4, stop screw, 5, spring, 6, the flush end holding screw, 7, copper sheathing, 8, clock gauge.
Embodiment
With reference to the accompanying drawings the utility model is further qualified:
Be described further referring to 2 pairs of the utility model of accompanying drawing: after each component processing is intact, earlier be installed in spring 5 and measurement and positioning axle 3 in the endoporus of measuring unit 2 by stop screw 4, then measuring unit 2 is placed on and tests on the axle 1, by flush end holding screw 6 clock gauge 8 and copper sheathing 7 are fixed on the measuring unit 2 at last.It should be noted that when clock gauge 8 is installed, firmly the bottom surface of measuring unit 2 and the end face of testing axle 1 are adjacent to motionlessly earlier, milscale is depressed made pointer rotate 1 circle then, by flush end holding screw 6 clock gauge 8 and copper sheathing 7 are fixed on the measuring unit 2 at last.
Elder generation is adjacent to the clock gauge zero clearing of motionless back with the bottom surface of measuring unit 2 with the end face of testing axle 1 when using special use to test tool, and then carries out parts measurement.It should be noted that will whether be zero-bit through commonly used if testing a check and correction clock gauge.
Described spring 5 relies on the elasticity of self that the end face of measurement and positioning axle 3 with tested part tightly touched, and guarantees the measuring accuracy of part.
Described milscale is fastened on the measuring unit 2 by flush end holding screw 6.
Stop screw 4 has two effects: 1, restriction measurement and positioning axle 3 does not break away from measuring unit 2.2, limit feature is oversize damages clock gauge above the clock gauge stroke.
The gauge head bar of 7 pairs of clock gauges 8 of described copper sheathing shields.
The beneficial effects of the utility model embody in the use: because the material that the tool critical piece is tested in this special use is through Overheating Treatment, hardness is higher, and is durable in use; Use easy to operately, save work step, efficient improves; So owing to use the amesdial precision higher.
