Abstract

The utility model discloses a kind of direct-reading Special length measuring apparatus of ratio-frequency welded tube, it mainly includes base plate, main scale, vernier, digital display instrument and fixing measuring jaw, described main scale is vertical shape and is fixedly mounted on base plate, the bottom of vernier is provided with the spill chute corresponding with main scale width, vernier is slidably mounted on main scale by the spill chute of its bottom, described fixing measuring jaw tabular being fixed on base plate and with main scale lower end is perpendicular that be square contacts, described digital display instrument is arranged on vernier, on this vernier, be also provided with the movable measuring jaw paralleling with fixing measuring jaw, on described base plate, offer the locating slot paralleling with main scale, the utility model advantage is: structure is very simple, survey measurements is convenient directly perceived, not only can effectively avoid body distortion, but also can avoid body owing to just not placing, and affect measurement result, thereby greatly improve measuring accuracy.

Description

The direct-reading Special length measuring apparatus of ratio-frequency welded tube
Technical field
The utility model relates to the technical field of measurement mechanism, more particularly relates to the technical field of ratio-frequency welded tube measurement mechanism.
Background technology
Ratio-frequency welded tube is one of core component of heat exchanger system product, and heat exchanger can be widely used in aviation, electric power, industry and civil air conditioner, chemical industry, boats and ships, automobile, locomotive, traffic, machinery and the industry such as metallurgical.The quality of ratio-frequency welded tube quality directly has influence on the heat exchange performance of heat exchanger, at present, high performance ratio-frequency welded tube adopts the manufacture of coating aluminum alloy material to form mostly, it has good heat exchange performance, the advantages such as intensity is high and lightweight, adopted by vast heat exchanger producer, in the production run of coating aluminium alloy ratio-frequency welded tube, often need to detect its pipe range, to reach client's user demand, the measuring method of pipe range is that coating aluminium alloy ratio-frequency welded tube to be measured is rested on vernier caliper at present, read length numerical value by visual scale mark, the weak point that this metering system exists is, the one, carry out reading numerical values by visual scale mark, measuring speed is slower, the workman that can not identify vernier caliper can't do surveying work, the 2nd, because the own body of coating aluminium alloy ratio-frequency welded tube to be measured is thinner, in the time measuring, in the time that the two ends of vernier caliper push against the two ends of body, easily make body distortion, different workmans measure, the dynamics using is inconsistent, causes measured the possibility of result different, has affected and has estimated precision, the 3rd, in the time measuring, thinner body is placed between vernier caliper, there will be body just not placing, and occurs crooked situation, also can affect measuring accuracy.
Utility model content
It is a kind of simple in structure that the purpose of this utility model provides in order to solve above-mentioned deficiency exactly, and survey measurements is convenient directly perceived, can greatly improve the direct-reading Special length measuring apparatus of the ratio-frequency welded tube of measuring accuracy.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
The direct-reading Special length measuring apparatus of ratio-frequency welded tube, it mainly includes base plate, main scale, vernier, digital display instrument and fixing measuring jaw, described main scale is vertical shape and is fixedly mounted on base plate, the bottom of vernier is provided with the spill chute corresponding with main scale width, vernier is slidably mounted on main scale by the spill chute of its bottom, described fixing measuring jaw tabular being fixed on base plate and with main scale lower end is perpendicular that be square contacts, described digital display instrument is arranged on vernier, on this vernier, be also provided with the movable measuring jaw paralleling with fixing measuring jaw, on described base plate, offer the locating slot paralleling with main scale.
The length of described locating slot is corresponding with main scale.
Between described fixing measuring jaw and vernier, extension spring is installed.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: structure is very simple, adopt digital display to show reading value, survey measurements is convenient directly perceived, when measurement, first vernier is moved to upper top, again body to be measured is directly placed in locating slot, the vernier of loosing one's grip, allow vernier glide under the effect of himself gravity, while touching body upper end Deng its movable measuring jaw, stop voluntarily, so not only can effectively avoid body distortion, but also can avoid body owing to just not placing, and affect measurement result, thereby greatly improve measuring accuracy, can also be by extension spring be installed between fixing measuring jaw and vernier, reach the effect that improves measuring speed.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the direct-reading Special length measuring apparatus of ratio-frequency welded tube, it mainly includes base plate 1, main scale 2, vernier 3, digital display instrument 4 and fixing measuring jaw 5, described main scale 2 is vertical shape and is fixedly mounted on base plate 1, the bottom of vernier 3 is provided with the spill chute corresponding with main scale 2 width, vernier 3 is slidably mounted on main scale 2 by the spill chute of its bottom, described fixing measuring jaw 5 be square tabular be fixed on base plate 1 and with perpendicular contact the in main scale 2 lower ends, described digital display instrument 4 is arranged on vernier 3, this digital display instrument 4 all shows that with existing digital display the digital display instrument of vernier caliper is identical with main scale with main scale 2, on this vernier 3, be also provided with the movable measuring jaw 6 paralleling with fixing measuring jaw 5, on described base plate 1, offer the locating slot 7 paralleling with main scale 2, the length of this locating slot 7 is corresponding with main scale 2, between fixing measuring jaw 5 and vernier 3, extension spring is installed.
