Description

The air pressure transmitter

Technical field

The utility model is about a kind of launcher; Particularly about a kind of air pressure launcher.

Background technique

For various industries, the impact resistance of product is concerning whether product can generally use or transport in the process and damage, and influences the reliability of product.Whether durable or easy inefficacy of product is concerning the confidence of user to each company's product quality especially.Therefore, for each industrial circle, the test that product must pass through is often classified in the shock-resistant test of product as before a large amount of production.With recent development fast solar opto-electronic board be example; this solar opto-electronic board must be arranged at outdoor environment usually to absorb solar energy; yet for improving the efficient that it absorbs solar energy, solar opto-electronic board there is no any barrier usually outward and only is provided with the protection housing that is made of a tempered glass as a means of protection.Therefore, this protection housing must effectively be kept out the contingent any impact of outdoor environment, for example: foreign matter fall impacting or hail impact etc.In other words, the test of bump takes place in the protection housing of solar opto-electronic board in the time of must falling by simulation hail or other foreign matters, is subjected to hail or other foreign matter drop impact when avoiding can't impact-resistant solar opto-electronic board is actual out of doors using and damages.

From the above, mainly be divided into two kinds with at present known bump test means in order to the test solar opto-electronic board, a kind of is the bump test of utilizing weight to fall naturally; Another kind of then be to utilize launcher to penetrate the bump test of an emitter.The former, owing to only utilize the usefulness of centrifugal force as rammer accelerations, so the height dimension of testing apparatus then is proportionate with the stroke speed of desire simulation, in other words, if the speed of required bump is faster, the height of testing apparatus is height more just.Apparently, the test specification that can simulate of this kind testing apparatus is very limited.Comparatively speaking, the latter should be comparatively feasible means with the simulation test that launcher penetrates emitter.

Generally speaking, the at present common means of utilizing launcher to penetrate emitter mainly can be divided into following three classes:

1. the explosion thing that ignites, the blast that produces when burning by the explosion thing can be converted to the kinetic energy that promotes emitter, and emitter is penetrated;

2. utilize a pressure fluid to promote emitter, make emitter obtain to launch behind the kinetic energy; And

3. utilize actuator to promote emitter.

Above-mentioned first kind of means because of the explosion thing has certain danger, are therefore considered based on safety, and its application is restricted mostly.On the other hand, above-mentioned the third means, for the speed of controlling emitter and the demand that meets transmitted at high speed, actuator itself must have the ability of accurate control rate and load.For example, if when using linear motor as actuator, this linear motor needs high-power power supply supply and huge control apparatus to drive and to control linear motor usually.If use general revolution motor, also certainly will need to be equipped with rotation is converted to the driving mechanism that high-speed linear moves, to promote emitter as actuator.Therefore, the means of testing that uses actuator to promote emitter has equipment complexity and the too high problem of cost usually.

Compare aforementioned two kinds of means of testing, above-mentioned use pressure fluid is comparatively general with the test mode of quickening emitter.Yet, this kind testing apparatus must utilize mostly one independently the pressure accumulation groove connect between pressurized gas source and launcher, make not only in the use that the volume of overall emission equipment is excessive, occupy big quantity space, and also very inconvenience.

In view of this, for meeting the demand of impact test, how to overcome existing emission system have dangerous high, complexity is too high, volume is excessive or use problem such as inconvenience, is technical field problem demanding prompt solution for this reason.

Summary of the invention

A purpose of the present utility model is to provide a kind of air pressure transmitter, can penetrate an emitter at a high speed, and have can precisely control, safe, characteristic such as complexity is low, conformability is high and volume is little.

For achieving the above object, an air pressure transmitter of the present utility model and a pressurized gas source gas communication, and comprise a pressure accumulation groove, a cylinder body and a piston.Wherein, the pressure accumulation groove comprises a pressure accumulation chamber, and piston is to be snug fit in the cylinder body, in order to the gas communication between the control pressure accumulation chamber and the external world.Pressurized gas source stores a superheated steam in the pressure accumulation chamber via cylinder body, and makes the superheated steam compressing piston in the cylinder body, makes piston intercept gas communication between the pressure accumulation chamber and the external world substantially.When removing pressurized gas source, the gas that piston is opened between the pressure accumulation chamber and the external world leads to, and makes the superheated steam pressure accumulation chamber in can promote emitter and launches and go out from the air pressure transmitter.Wherein, the air pressure transmitter is suitable can be controlled pressurized gas source and whether be connected to the gas transmitter, emitter is penetrated at a high speed with one, and the air pressure of regulation and control superheated steam penetrates the firing rate of emitter with control.Thus, air pressure transmitter of the present utility model need not use the explosion thing, and has precisely control, high security, simple in structure, advantage such as conformability is high, and volume is little.

For this above-mentioned purpose, technical characteristics and advantage can be become apparent, hereinafter be to cooperate appended graphic being elaborated with preferred embodiment.
