Description
Technical field
The present invention relates to the architecture advances of micrometer inside caliper, more particularly, relate to the external member of improving in micrometer inside caliper the measurement result real-time response.
Background technology
Boats and ships, during building, need to be measured with micrometer inside caliper diameter and the concentricity in stern tube, rudder gudgeon hole, or measure diameter and the concentricity of processing, built-up member with micrometer inside caliper; It is peculiar to vessel that (pedestal of (or other industry) equipment, before location, need to coordinate wire to check the flatness of pedestal with micrometer inside caliper.The method of diameter is that an end of milscale is leaned to the side at the workpiece inwall, and the bee-line that measures the opposite side of workpiece inwall with the measuring junction of milscale is the diameter of workpiece; The measuring method of concentricity is to draw the wire that a diameter is 0.3mm-0.7mm in the middle of the endoporus of workpiece, with interior, through miking endoporus different cross section, checks up and down the concentricity of different cross section apart from the distance of wire; The measuring method of pedestal flatness is first to weld two blocks of bonding jumpers in the pedestal both sides, draws the wire of a 0.3mm-0.7mm between two bonding jumpers, measures the pedestal relevant position with micrometer inside caliper and checks the flatness of pedestal apart from the height of wire.The shortcoming of these metering systems has:
1, when measuring diameter, when an end of milscale leans the side at the workpiece inwall, one end of measuring head need to just lean the opposite side at the workpiece inwall, the dynamics leaned needs gauger's measuring head that slidably reciprocates to feel with hand, owing to measuring people's difference, cause leaning dynamics also different, so, the data that record are also different, have very large artificial measuring error;
2, slidably reciprocate and interiorly through the miking head, feel to lean dynamics with gauger's hand, can make the wearing and tearing of measuring head increase the weight of, reduce the serviceable life of milscale;
3, when measuring concentricity and flatness, owing to will coordinating wire, measure, and wire used is usually between 0.3mm-0.7mm, therefore, survey crew with the naked eye is difficult to see clearly the measuring head of micrometer inside caliper and whether just encounters wire, particularly, when completing this work for a long time, there is very large artificial measuring error;
4, whether encounter wire for the measuring head that can clearly see milscale, a clever line laborer has invented a kind of method: be exactly before each the measurement, smear gently some chalk powders on the measuring head of milscale with chalk, work as chalk powder during measurement and come off, just mean whether measuring head just encounters wire.But this method is very strict to the thickness requirement of chalk powder, the gauger is difficult to the chalk powder consistency of thickness that assurance is smeared at every turn, and therefore, this method is only improved the labour intensity of human eye, can't change artificial measuring error;
5, Measuring Time is infinitely extended, and because operating personnel are holding the micrometer inside caliper of metal material for a long time, micrometer inside caliper can cause the generation of survey instrument error because of expanded by heating, and incurs loss through delay construction speed;
In sum, this measuring method can produce larger artificial measuring error, has had a strong impact on construction quality and operating efficiency.
Summary of the invention
For during improving shipbuilding or other industry in construction period, use micrometer inside caliper to diameter of work, concentricity with to the flatness measurement accuracy before and after the various device base stand location, shorten the engineering time, improve operating efficiency, the invention provides a kind of micrometer inside caliper that is provided with luminous external member.During the present invention mainly is applicable to shipbuilding or other industry in construction period, use micrometer inside caliper to diameter of work, concentricity with to the flatness measurement before and after the various device base stand location.
In order to achieve the above object, a kind of micrometer inside caliper based on luminous external member of the present invention, comprise the leading portion chi body and the back segment chi body that dock with threaded column, threaded hole mode, be respectively arranged with the irony electric conductor to inner threaded ends from the measurement end face of outer end in described leading portion chi body and back segment chi body.Connected a luminous external member with threaded column, threaded hole mode respectively between described leading portion chi body and back segment chi body, described luminous external member comprises the main body of outside tubular, described main body is that the insulation transparent material is made, and establishes two contact blocks, two springs, a Battery pack, a luminophor in cylinder.Wherein, two described contact blocks lay respectively at the front and back end of described main body and, respectively by described spring support top, stretch out the front/rear end of described main body; Two described springs are connected in series described battery and described luminophor by wire respectively.Under the use state, described luminous external member is screwed in the middle of described leading portion chi body and back segment chi body, and described irony electric conductor, described contact block, described spring, described battery, the series connection of described luminophor are a conducting channel.
Wherein, the medial extremity of described contact block is stuck in the hole of described body end with step cylinder form.
In addition, the present invention requires the main material of luminous external member hard, modification in use can not occur and for the transparent body, can with the naked eye see that whether luminophor is luminous.
The present invention by using luminous external member in micrometer inside caliper, effectively be reduced in and use micrometer inside caliper to measure the personal error in the relative dimensions data procedures, thousand minutes measurement data accuracys of internal diameter have been improved, convenient, flexible during use, time saving and energy saving, for the measurement precision that improves micrometer inside caliper provides reliable technical guarantee.Beneficial effect of the present invention is:
1, this luminous external member has versatility, installation and simple and easy to use.
2, when use is equipped with the micrometer inside caliper measuring workpieces diameter of luminous external member, no longer need the gauger to feel the dynamics that leans of milscale with hand, that is to say, according to luminophor, the data that any survey crew is surveyed are all the same;
3, when use is equipped with the micrometer inside caliper measuring workpieces diameter of luminous external member, no longer need the gauger to slidably reciprocate and interiorly through the miking head, feel to lean dynamics, extend the serviceable life of survey instrument, reach the purpose of cost efficiency.
4, when use is equipped with the micrometer inside caliper measuring workpieces concentricity of luminous external member and equipment base flatness, the gauger can clearly see whether the measuring head of milscale contacts with wire by luminophor, alleviate gauger's labour intensity, improved the accuracy of DATA REASONING;
5, no matter be diameter, the concentricity of measuring workpieces, or the flatness of measuring equipment pedestal, the use of this luminous external member can be shortened Measuring Time greatly, and this has just been avoided the measuring error that its expanded by heating is caused because holding for a long time milscale.
To sum up, use luminous external member in micrometer inside caliper, not only can shorten Measuring Time, alleviate gauger's labour intensity, key is to avoid the generation of artificial measuring error, greatly improves it and measures precision.
