Description

Automatic measuring instrument for outer diameter roundness of enameled wire

Technical Field

The utility model relates to an automatic enameled wire roundness measuring instrument capable of automatically measuring the roundness of the cross section of an enameled wire at multiple angles and multiple points, belonging to the field of automatic enameled wire measuring instrument manufacturing.

Background

The traditional measuring method is that an inspector uses a micrometer to measure the outer diameter of the enameled wire from multiple angles (three angles generally), at different measuring points (three measuring points generally), the maximum and minimum diameters of the enameled wire are obtained after manual reading and recording and analysis, and the roundness of the enameled wire is obtained by calculating the difference value between the maximum outer diameter and the minimum outer diameter at the same point. The enameled wire is soft and easy to deform due to the fact that the outer diameter factor (diameter is smaller than 0.1 mm) of the enameled wire is difficult to measure in the whole measuring process, artificial factors are greatly affected during multi-angle measurement, and the measuring difference is large under the comprehensive interference of objective factors and main factors. It is difficult for enterprises to control the consistency and authenticity of the detection results.

The design scheme is as follows: in order to achieve the above design objective. On the basis of the background technology, 1, an existing outer diameter measuring instrument is adopted as a measuring and reading tool for measuring the outer diameter measuring point of the enameled wire. 2. The power output shafts of the two rotating motors are opposite and are clamped by the enamelled wire clamp to form a horizontal line, and the multi-angle measurement of the roundness diameter of the enamelled wire is completed under the drive of the rotating motors, namely, the roundness (360 degrees) of the enamelled wire is equally divided into N angles, for example, when 12 degrees are one measurement angle, the circumference of the enamelled wire is equally divided into 30 measurement points with different angles in 360 degrees. 3. The outer diameter measuring instrument is fixed on the translation screw rod, and the translation screw rod drives the outer diameter measuring instrument to translate, so that the measurement of the roundness value of the cross section of the enamelled wire with the maximum number of 4 can be automatically completed under the instruction of the PLC. 4. The man-machine interaction touch screen can facilitate operators to finish adjustment of measurement parameters of the enamelled wires to be measured according to quality requirements of the enamelled wires with different requirements.

The measuring steps are as follows: 1) The operator clamps and fixes the two ends of the enameled wire on the measuring instrument by using the clamp, and the rest detection processes are no longer interfered by personnel. 2) After an operator clicks a start button on the touch screen, the rotating motor rotates by 12 degrees according to measurement requirements (such as 30 angles measured by each measuring point), the controller controls the outer diameter measuring instrument to read the measured value and store the measured value into a controlled memory, and the effective reading value and number are recorded. 3) After the instrument measures 360 degrees, the outer diameter measuring instrument translates to one side by a distance through the translation screw rod, and the distance can be set through the touch screen. 4) After the translation has stopped, the instrument repeats step 2), and the value of the second measurement point is measured and recorded. 5) According to the setting of the touch screen, the instrument can automatically collect and record data of 4 measuring points. 6) After the 4 groups of measurement activities are finished, the average outer diameter, the maximum outer diameter, the minimum outer diameter and the roundness value of each group of samples are automatically displayed on the touch screen. 7) After the measurement is finished, the outer diameter measuring instrument automatically resets to the initial position through the translation screw rod, so that the next measurement is convenient. 8) An operator can directly observe and record the required data to obtain roundness quality information of the cross section of the enameled wire product. 9. The instrument is provided with the communication interface, so that the instrument can be conveniently connected to an upper computer to automatically input measurement data into an information system database, and an ERP management system of an enterprise can conveniently carry out mathematical statistics and analysis on product quality data.

The technical scheme is as follows: the utility model provides an enameled wire roundness measuring instrument, PLC controller and translation lead screw are located the base respectively, and human-computer interaction touch-sensitive screen is located the PLC controller, and translation lead screw one end and step motor drive shaft connection, step motor signal input termination PLC controller's signal output part, external diameter measuring instrument are fixed on the translation lead screw, and two rotating electrical machines are located the base and are equipped with enameled wire anchor clamps respectively on the power output shaft of two rotating electrical machines respectively through the motor support relatively, and two rotating electrical machines signal input termination PLC controller signal output part.

After the inspector sets the measurement parameters through the touch screen 1, the controller instructs the motor to start the button. The touch screen 1 sends a motion instruction to the controller to control the rotation angles of the two rotating motors 3. The two rotating motors 3 rotate by a certain angle according to the program setting (the angle is obtained by dividing the measurement number set by the touch screen by 360), and then pause for S seconds (S can be set by the touch screen 1). During the standstill, the outside diameter measuring instrument 5 measures the outside diameter of the enamel wire 4 and stores the read value into the memory of the controller. After each rotation of the two rotating motors 3 for a certain angle, the two rotating motors stop for S seconds, and the outer diameter measuring instrument 5 measures and records one data. After the two rotating motors 3 rotate 360 degrees, one measuring point is measured. The stepper motor 8 is then moved to drive the translation screw 6 to move M mm (M settable) to the next measurement point. After the measurement points are moved, the two rotating motors 3 and the outer diameter measuring instrument 5 repeat the previous measurement actions, and data are recorded in the control memory. The translation screw 6 is then moved by a further M mm to the next measuring point. The previous measurement actions are repeated.
