technical field

The new model belongs to a measuring device, in particular to a fast strip spring height measuring device.

Background technique

In the production of nuclear fuel elements, the height of the springs in the grid, which is an important component, must be strictly controlled to ensure the normal operation of the grid in the reactor. At present, we use the manual observation and reading method of a single spring height. Each spring on a strip needs to be measured step by step, which is not intuitive for inspectors to use, and it is very difficult to trace the product quality and the measurement efficiency is low.

Utility model content

Aiming at the defects of the prior art, the present invention provides a fast strip spring height measuring device.

The new model is realized as follows: a fast strip spring height measuring device, including a base plate, a movable front measuring plate and a fixed rear measuring plate are arranged on the base plate, and a spring-loaded measuring plate is arranged between the movable front measuring plate and the fixed rear measuring plate. At the position where the tested strip is placed, several inductive probes are set at the height of the tested spring, and the inductive probes are used to measure the height of the matching position spring and output.

In the device for measuring the height of a rapid strip spring as described above, a positioning adjustment block is provided on the bottom plate, and the positioning adjustment block is used to position and fasten the strip to be tested.

A fast strip spring height measuring device as described above, wherein, the position of the measuring plate before the activity can be moved, a bearing is arranged on the bottom plate, an eccentric wheel assembly is arranged on the bearing, and the end of the eccentric wheel assembly is arranged before the activity. Behind the measuring plate, the rotating eccentric wheel assembly can drive the movable front measuring plate to move back and forth.

In the device for measuring the height of a rapid strip spring as described above, a guide rail assembly is arranged on the bottom plate, and the movable front measuring plate moves back and forth along the guide rail assembly.

In the above-mentioned fast strip spring height measuring device, a signal wire pressing plate is arranged on the bottom plate for fixing the signal wire.

In the above-mentioned fast strip spring height measuring device, there are 34 electric measuring heads in total.

In the above-mentioned fast strip spring height measuring device, the signal detected by the electric measuring head is transmitted to an external computer, and the data is processed by the external computer.

The effect of the new type is: with the development of nuclear power, the demand for grids is increasing, and the variety of grids is also increasing, and the original measurement technology can no longer meet the needs. A fast strip spring height measurement The device can be used to quickly detect the height of the strip spring on the production line, and visually display the actual status of the spring height, which is convenient for workers to adjust and repair their products quickly and in a targeted manner. The computer automatically displays the measured value of the spring height and judges whether it is qualified or not. , which greatly improves the production efficiency of workers and the intuitiveness of product quality judgment.

This device is a new type of measuring instrument that can measure the height of up to 34 springs at one time. On this device, the height measurement of various types of strips can be realized by changing different positioning adjustment blocks.

Detailed ways

The present application is a rapid strip spring height measurement device. As shown in Figure 1, the positioning adjustment block can be customized according to the size of the strip, and has the function of positioning and limiting. The positioning block is fixed on the base by bolts, and the replacement is convenient. The strip is placed vertically on the positioning block, so that the lower surface of the strip can be positioned on the same horizontal line, so as to ensure that the highest point of the spring is on the same horizontal line. Making matching positioning blocks for different types of strips can realize the positioning of different types of strips.

First, the measuring plate 5 is moved back, and the calibration block is selected according to the type of the strip. The operator correctly places the calibration block on the positioning adjustment block to perform zero alignment of the device. Turn the eccentric assembly 3 so that the movable front measuring plate compresses the strip and rests against the fixed rear measuring plate. At this time, the flat probe is pressed against the calibration block, the inductive probe 9 starts to work, and the computer count is cleared. The computer will automatically collect and process the data of 34 displacement sensors according to the selection requirements. After the equipment calibration operation is completed, the measuring plate 5 returns to the starting position before the activity. The eccentric component is convenient for the operator to load and unload, and it has a uniform clamping effect on the workpiece. Press the flanged plungers 10 and 11 to ensure that the movable front measuring plate 5 and the fixed rear measuring plate 6 are pressed against the measured strip. The pressing force is provided by the pressing flanged plungers 10 and 11 .

The operator puts the tested strip in the direction, turns the eccentric wheel and locks the tested strip, 34 sensors are displaced along the spring height direction, and the computer will record all the displacement values. The computer automatically measures the height of the springs on up to 34 strips, and automatically judges whether the height of the springs on the tested strips is qualified. The state of the tested spring is displayed in different colors. After the data is collected, it is saved and the measured strip is taken out, and the measurement of the strip is completed. The measurement time of a single strip of the device is about 3 seconds, and the measurement efficiency is greatly improved. After testing, the contact force value of the measuring head is about 0.25N. Compared with the dial indicator measurement method, the contact force value is greatly reduced, the spring surface is not damaged, and the measurement state is closer to the real state of the workpiece.

The measurement software system can compile measurement programs for different types of strips, and realize the visualization, storage and statistical analysis of measurement results. The software interface can display in real time: the current measured value of the sensor, the upper and lower tolerances, and bar graphs with different colors (green means qualified, yellow means close to the limit, and red means unqualified) to show whether it is out of tolerance, which is convenient for the operator to adjust the spring assembly The spot welding position is shown in Figure 2. The measurement process flow chart is shown in Figure 3.

In conclusion, the present invention can effectively detect the height of the strip spring and automatically store the measurement results. The invention has the advantages of high graphic visualization, high efficiency and high degree of automation for the height detection of the strip spring.
