Abstract
The invention discloses a clamping plate outside diameter dial indicator which solves the problems that an outside micrometer is adopted in existing rotating shaft grinding bearing position size measuring, so that the reject rate stays at a high level, production efficiency is low, and manufacturing cost is high. The clamping plate outside diameter dial indicator comprises a U-shaped clamping plate, the left end face of an upper rod of the U-shaped clamping plate is provided with a vertical clamping groove rightwards, a vertical adjusting hole is formed in the clamping groove, a casing pipe is arranged in the adjusting hole in a penetrating mode, the upper end of the casing pipe is fixedly provided with a dial indicator body, a movable measuring rod is arranged in the casing pipe, a pre-tightening spring is arranged on the movable measuring rod in a sleeved mode, a lock screw is arranged on the upper rod of the U-shaped clamping plate in a penetrating mode, a fixed measuring rod is arranged on a lower rod of the U-shaped clamping plate in a penetrating mode, and a compression screw is screwed on the U-shaped clamping plate. A positioning rod is arranged on a vertical rod of the U-shaped clamping plate in a penetrating mode, and a compressing screw I is screwed on the vertical rod of the U-shaped clamping plate. The clamping plate outside diameter dial indicator solves the problem that errors exist due to the manual measurement, and the one-time detection qualification rate of grinding of a rotating shaft is improved.
Description
Technical field
The present invention relates to machine shaft measurement mechanism, be 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 ensures 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) movable outside micrometer gauge head 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 present invention 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 present invention adopts 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 fixing measuring staff that upper diameter is greater than lower diameter, and on U-shaped clamp, be screwed with fore-and-aft direction setting and the housing screw with fixing measuring staff sidewall contact, on U-shaped clamp montant, be installed with middle part and horizontally disposed backstay between movable measuring staff and fixing measuring staff, and on U-shaped clamp montant, be screwed with fore-and-aft direction setting and the housing screw I with backstay sidewall contact.
While measuring operation, according to institute's measured motor shaft bearing position diameter dimension, air line distance between movable measuring staff and fixing measuring staff is adjusted to the position that is slightly less than surveyed shaft bearing position diameter, and movable measuring staff and fixing measuring staff tip position and backstay center symmetry, and the left end of backstay is adjusted to the position of surveyed bearing position radius; When measurement, clamp plate type outside micrometer is inserted along rotating shaft bearing of motor position outer round surface, movable measuring staff, fixing measuring staff are contacted with the upper and lower plain line of shaft bearing position cylindrical respectively, in the time that 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.
Reasonable in design of the present invention 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 ensured rotating shaft grinding quality, reduce rotating shaft manufacturing cost simultaneously, had advantages of simple in structure, easy to operate and cost is low.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1-U type clamp, 2-clock gauge, the movable measuring staff of 3-, 4-preloading spring, 5-tie down screw, 6-fixes measuring staff, 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 fixing 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 the housing screw 7 with fixing measuring staff 6 sidewall contacts, on U-shaped clamp 1 montant, be installed with middle part and horizontally disposed backstay 8 between movable measuring staff 3 and fixing measuring staff 6, and on U-shaped clamp 1 montant, be screwed with fore-and-aft direction setting and the housing screw I9 with backstay 8 sidewall contacts.
In specific implementation process, preloading spring 4 be in order to make movable measuring staff 3, that fixing measuring staff 6 contacts with the upper and lower plain line of rotating shaft cylindrical is 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.
