The invention has the advantages that: the system has a simple structure, high measuring accuracy, measuring stability and effectiveness and low production cost, and is convenient to popularize and use.
Description
Technical field
The present invention relates to a kind of distance measuring equipment, be specifically related to a kind of leading screw of measuring equipment adjustable gib spacings such as crest welder, reflow machine and regulate range measurement system.
Background technology
At present, in the actual production process of crest welder and reflow machine, there are two kinds of metering systems in the distance measurement of its adjustable gib: a kind of technician of being directly measures with ruler; Another is to form test macro with scrambler, PLC, man-machine interface or computing machine to measure.First kind of metering system is more original, though its cost is very low, but there are very mistake in its measurement result and product actual pitch, second kind of metering system measurement result and product actual pitch error are little, but exist to measure cost problem high and that measurement data can not be preserved when outage, above-mentionedly form test macro by scrambler, PLC, man-machine interface or computing machine to cause a lot of equipment producer to be unwilling to use.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, provide a kind of leading screw to regulate range measurement system, it is simple in structure, easy to use, measuring accuracy is high, measurement stability and validity is strong, production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution used in the present invention is: a kind of leading screw is regulated range measurement system, comprise the left plate and the right plate that be arranged in parallel, it is characterized in that: be arranged with leading screw and feed rod between described left plate and the right plate in parallel, between leading screw and the feed rod sliding shoe is installed, described leading screw is connected with the gear main shaft, this gear is connected with and is used to detect and measure the multiturn potentiometer that leading screw rotates the number of turns, and this multiturn potentiometer is connected with comprehensive digital display instrument by data line.
Described gear adopts variable-speed gear system or worm and gear speed change system.
Described comprehensive digital display instrument is made up of built-in power, data reduction and a memory module and display module.
Described leading screw all is provided with left plate is vertical with right plate with feed rod.
Described sliding shoe inside is provided with screw thread and matches with leading screw.
Described gear main shaft is connected by shaft coupling with leading screw one end.
The present invention compared with prior art has the following advantages:
(1) simple in structure, easy to use.It is simple in structure that this leading screw is regulated range measurement system, and operating personnel get final product complete operation through simple study, and are very easy;
(2) volume is less, is convenient to transportation.It is little, in light weight that this leading screw is regulated the range measurement system volume, is convenient to very much transportation;
(3) measuring accuracy height.This leading screw is regulated range measurement system the straight line that the circumferential movement of leading screw is converted into sliding shoe is moved, because the pitch of leading screw is very little, and uses gear simultaneously, so can guarantee very high degree of accuracy when measuring.
Measurement data can continue to preserve when (4) cutting off the power supply.This leading screw is regulated range measurement system and is used the drawback of scrambler as signal conversion part usually at distance mearuring equipment in the past, has proposed to use multiturn potentiometer to replace the improvement of scrambler.Since the rotation each time of potentiometer all corresponding the variation of resistance, its each rotating cycle all corresponding an output voltage signal, convert by magnitude of voltage and can obtain the distance value that to measure, so just avoided the drawback of scrambler, thereby improved measuring accuracy, the measurement stability of system and measured validity because of the outage obliterated data;
(5) production cost low, be convenient to promote the use of.The element that this leading screw is regulated range measurement system is easy to produce, buy, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, technical scheme of the present invention is described in further detail.

Embodiment
A kind of leading screw is as shown in Figure 1 regulated range measurement system, comprise the left plate 1 and the right plate 2 that be arranged in parallel, be arranged with leading screw 3 and feed rod 4 between described left plate 1 and the right plate 2 in parallel, be slidingly fitted with sliding shoe 5 between leading screw 3 and the feed rod 4, described leading screw 3 is connected with gear 6 main shafts, this gear 6 is connected with and is used to detect and measure the multiturn potentiometer 7 that leading screw 3 rotates the number of turns, and this multiturn potentiometer 7 is connected with comprehensive digital display instrument 9 by data line 8.
As shown in Figure 1, gear 6 adopts variable-speed gear system or worm and gear speed change system.
As shown in Figure 1, comprehensive digital display instrument 9 is made up of built-in power, data reduction and a memory module and display module.
As shown in Figure 1, leading screw 3 and feed rod 4 all with left plate 1 and right plate 2 vertical settings.
As shown in Figure 1, sliding shoe 5 inside are provided with screw thread and match with leading screw 3.Screw thread can guarantee that sliding shoe 5 also moves thereupon when leading screw 3 rotates.
As shown in Figure 1, gear 6 main shafts are connected by shaft coupling with leading screw 3 one ends.
The course of work that leading screw of the present invention is regulated range measurement system is: left plate 1 and the right plate 2 of at first this leading screw being regulated range measurement system are fixed on corresponding support or the worktable.When leading screw 3 rotates, rotates by driving multiturn potentiometer 7 after gear 6 speed changes thereupon,, make suitable scale-up factor μ of existence between the rotation number of turns of multiturn potentiometer 7 and leading screw 3 by the gear ratio of appropriate design gear 6, be X=μ Y, X is the potentiometer rotating cycle in the formula; Y is the leading screw rotating cycle.
Rotation along with leading screw 3, the sliding shoe 5 that is slidingly mounted on leading screw 3 and the feed rod 4 also will move under the guide effect of the driving of leading screw 3 and feed rod 4, and the number of turns that the leading screw 3 by record turns over and known pitch value can calculate the distance that sliding shoe 5 moves easily.Because the number of turns of the rotating cycle of leading screw 3 and the rotation of multiturn potentiometer 7 is proportional, and the position of rotation of multiturn potentiometer 7 corresponding the magnitude of voltage of its output, draw the displacement of sliding shoe 5 so can convert from the magnitude of voltage of multiturn potentiometer 7 outputs, thus the measurement that realization is adjusted the distance.
After obtaining output voltage from multiturn potentiometer 7, just can be input to comprehensive digital display instrument 9 by data line 8 and carry out the processing of voltage signal, the final numerical value that shows sliding shoe 5 displacements on its screen is finished the measurement of adjusting the distance.
The above; it only is preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every according to the technology of the present invention essence to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solution of the present invention.
