Description
Technical Field
The utility model discloses an automatic copper column pressure measuring device, and belongs to the technical field of pressure detection.
Background
A pressure sensor is a device or apparatus that can sense a pressure signal and convert the pressure signal into an electrical signal that can be output according to a certain rule.
In the production process of some thermal weapons such as guns, artillery and the like, weapon bore pressure needs to be measured to test the performance of the weapons, and an electrical measurement method and a copper column pressure measurement method are generally adopted, wherein the copper column pressure measurement method is more accurate and practical; the copper column pressure measuring method is an important measuring means in a conventional weapon bore pressure measuring system, under the action of bore pressure, the copper column generates permanent plastic deformation, the gas pressure of gunpowder is measured according to the deformation, and the maximum bore pressure of propellant powder is converted according to the height of the copper column before and after pressing.
Before each test, the test recording personnel are required to manually measure the height of the copper cylinder before pressing, a test bomb is shot after the copper cylinder bore pressure correction value is calculated according to the copper cylinder pressure gauge, then the test recording personnel find the bore pressure value according to the copper cylinder pressure gauge after manually measuring the height of the copper cylinder after pressing, and finally the maximum bore pressure value of the test bomb is calculated according to the copper cylinder bore pressure correction value. In the process, all calculation and measurement processes need manual measurement and calculation by test recording personnel, so that the time is very long, and the subsequent data processing is difficult.
Disclosure of Invention
Aiming at the defects in the prior art, the utility model provides an automatic copper column pressure measuring device to solve the defects in the prior art.
In order to solve the problems of the prior art, the technical solution of the utility model is as follows:
the automatic copper column pressure measuring device is characterized in that a copper column 1 is fixed at the center of the upper surface of a coding disc 2 which rotates horizontally, the center of the lower surface of the coding disc 2 is fixedly connected with a coupler 3 of a stepping motor 4 and can be driven by the stepping motor 4 to rotate, the stepping motor 4 is connected with a driver 5, a laser length measuring instrument 6 is placed above the copper column 1 and used for measuring the length change of the copper column 1, and the laser length measuring instrument 6 is connected with an industrial control computer 7.
The device can realize multiple times of measurement through non-contact measurement, and the precision realized through multi-point measurement is higher. And a laser length measuring instrument (6) is placed at the oblique upper end of the copper column (1) to record the height change of the copper column (1), when the driver 5 drives the motor (4) to rotate to drive the coding disc (2) to rotate, the copper column (1) is also driven by the coding disc (2), and the laser length measuring instrument (6) records different points. The laser length measuring instrument (6) is connected with the industrial control computer (7), can display the height values of the copper column (1) before and after pressing in time, records the height values, and can check the corresponding pressure value according to the pressure altimeter of the copper column (1).
Compared with the prior art, the utility model has the beneficial effects that: the device is not the size of direct pressure measurement, but utilize laser length measuring appearance (6) to go to measure the height before and after copper post 1 bears the pressure, utilize the relation that difference in height and pressure correspond to obtain the pressure value this moment, the device's laser length measuring appearance 6 and object contactless, because only copper post 1 and object contact, even copper post 1 has the damage, but the difference in height of same pressure different time through the copper post is unchangeable, the difference in height that only can be copper post 1 that laser length measuring appearance 6 measured, so the device can used repeatedly, and the device can directly read out the difference in height value of copper post, can directly utilize the difference to find the pressure value that corresponds with it. Not only reduces labor force, but also reduces errors caused by artificial reading, and improves working efficiency and accuracy.

Detailed Description
The technical scheme of the utility model is further detailed in the following by combining the drawings and the embodiment:
as shown in figure 1, the automatic copper column pressure measuring device fixes a copper column 1 at the center of the upper surface of a coding disc 2 which rotates horizontally, the center of the lower surface of the coding disc 2 is fixedly connected with a coupler 3 of a stepping motor 4 and can be driven by the stepping motor 4 to rotate, the stepping motor 4 is connected with a driver 5, a laser length measuring instrument 6 is arranged above the copper column 1 and used for measuring the length change of the copper column 1, and the laser length measuring instrument 6 is connected with an industrial control computer 7.
During specific operation, firstly, the fixed revolution of the stepping motor 4 is given through the driver 5, at the moment, the data of the laser length measuring instrument 6 are recorded, 3-6 different revolutions are respectively given, the revolutions are recorded at the same time, and the height value of the copper column 1 before pressing is recorded; after the copper post 1 bears the overpressure, the same parameters of the driver 5 are given to enable the stepping motor 4 to rotate to drive the copper post 1 to rotate, the parameters of the laser length measuring instrument 6 are recorded at the moment, the difference value of 3-6 groups of copper posts 1 is finally obtained, the parameters are consulted to obtain the pressure value, multipoint data analysis is carried out, and the measurement accuracy is favorably improved.
