Description

Clamp plate type outside micrometer
Technical field
The utility model relates to machine shaft measurement mechanism, is specially a kind of clamp plate type outside micrometer.
Background technology
Rotating shaft is the vital part in motor, and the quality of its quality will directly affect the overall performance of motor.The grinding of rotating shaft cylindrical, it is the critical process in whole rotating shaft processing, the crudy of shaft bearing position guarantees by grinding process, and the quality problems of bearing position are one of principal elements causing the different sound of motor bearings, and the normal operation of motor is had to important impact.
Existing rotating shaft grinding bearing position dimensional measurement, employing be common outside micrometer, common outside micrometer measuring process is: 1) the movable gauge head of outside micrometer is adjusted to and is slightly larger than shaft bearing position size; 2) manual rotation outside micrometer sleeve, makes the movable gauge head of outside micrometer contact with shaft bearing position cylindrical; 3) by the groove on fixing and quill, read shaft bearing position size.
Common outside micrometer is measured by manual rotation quill, because different people measures, manual measurement power has greatly, has little, artificial measuring error reaches 0.005mm left and right, shaft bearing position dimension overproof phenomenon is serious, and percent defective is high, and rotating shaft production efficiency is low, manufacturing cost improves, and has affected normally carrying out that rotating shaft is produced.
Summary of the invention
The utility model adopts outside micrometer to have the problem that disqualification rate is high, production efficiency is low and manufacturing cost is higher in order to solve the dimensional measurement of existing rotating shaft grinding bearing position, and a kind of clamp plate type outside micrometer is provided.
The utility model is to adopt following technical scheme to realize: clamp plate type outside micrometer, comprise the U-shaped clamp that vertical setting and notch are opened left, U-shaped clamp upper boom left side has vertical clamping slot to the right, in clamping slot, have vertical adjustment hole, in adjustment hole, be installed with sleeve pipe, sleeve pipe upper end is fixed with the clock gauge that is positioned at U-shaped clamp top, in sleeve pipe, be installed with and be threaded with clock gauge gauge rod and lower diameter is greater than the stepped movable measuring staff of upper diameter, on movable measuring staff and clock gauge gauge rod, cover has the preloading spring between its cascaded surface and U-shaped clamp upper boom lower surface, U-shaped clamp upper boom is installed with the lock-screw that is positioned at clamping slot place and fore-and-aft direction setting, on U-shaped clamp lower beam, be installed with the stepped fixedly measuring staff that upper diameter is greater than lower diameter, and on U-shaped clamp, be screwed with fore-and-aft direction setting and with the fixing housing screw of measuring staff sidewall contact, on U-shaped clamp montant, be installed with at movable measuring staff and fixedly middle part and horizontally disposed backstay between measuring staff, and on U-shaped clamp montant, be screwed with fore-and-aft direction setting and with the housing screw I of backstay sidewall contact.
While measuring operation, according to institute's measured motor shaft bearing position diameter dimension, by movable measuring staff and fixedly the air line distance between measuring staff adjust to the position that is slightly less than surveyed shaft bearing position diameter, and movable measuring staff and fixedly measuring staff tip position and backstay center are symmetrical, and the left end of backstay is adjusted to the position of surveyed bearing position radius; During measurement, clamp plate type outside micrometer is inserted along rotating shaft bearing of motor position outer round surface, make movable measuring staff, fixedly measuring staff contacts with the upper and lower plain line of shaft bearing position cylindrical respectively, when backstay contacts with cylindrical side, shaft bearing position element line, scale numerical value shown in clock gauge dish, be surveyed shaft bearing position diameter dimension, overcome the dimensional measurement of existing rotating shaft grinding bearing position and adopted outside micrometer to have the problem that disqualification rate is high, production efficiency is low and manufacturing cost is higher.
The utility model reasonable in design is reliable, clamp and two kinds of measurement forms of outside micrometer are combined together, while having avoided common outside micrometer to measure, the artificial measuring error easily producing, the once friendship inspection qualification rate that has improved rotating shaft grinding, has reduced the generation of rotating shaft rejection rate, has guaranteed rotating shaft grinding quality, reduced rotating shaft manufacturing cost simultaneously, had advantages of simple in structure, easy to operate and cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-U type clamp, 2-clock gauge, the movable measuring staff of 3-, 4-preloading spring, 5-lock-screw, 6-is measuring staff fixedly, 7-housing screw, 8-backstay, 9-housing screw I.
Embodiment
Clamp plate type outside micrometer, comprise the U-shaped clamp 1 that vertical setting and notch are opened left, U-shaped clamp 1 upper boom left side has vertical clamping slot to the right, in clamping slot, have vertical adjustment hole, in adjustment hole, be installed with sleeve pipe, sleeve pipe upper end is fixed with the clock gauge 2 that is positioned at U-shaped clamp 1 top, in sleeve pipe, be installed with and be threaded with clock gauge 2 gauge rods and lower diameter is greater than the stepped movable measuring staff 3 of upper diameter, on movable measuring staff 3 and clock gauge 2 gauge rods, cover has the preloading spring 4 between its cascaded surface and U-shaped clamp 1 upper boom lower surface, U-shaped clamp 1 upper boom is installed with the lock-screw 5 that is positioned at clamping slot place and fore-and-aft direction setting, on U-shaped clamp 1 lower beam, be installed with the stepped fixedly measuring staff 6 that upper diameter is greater than lower diameter, and on U-shaped clamp 1, be screwed with fore-and-aft direction setting and with the fixing housing screw 7 of measuring staff 6 sidewall contacts, on U-shaped clamp 1 montant, be installed with at movable measuring staff 3 and fixedly middle part and horizontally disposed backstay 8 between measuring staff 6, and on U-shaped clamp 1 montant, be screwed with fore-and-aft direction setting and with the housing screw I9 of backstay 8 sidewall contacts.
In specific implementation process, preloading spring 4 be for make movable measuring staff 3, fixedly measuring staff 6 contact with the upper and lower plain line of rotating shaft cylindrical firm, preloading spring power must be greater than the weight of clamp plate type outside micrometer simultaneously, otherwise, under the effect of whole outside micrometer gravity, clock gauge pin moves, the distortion of size numerical value of reading.
