Abstract

The invention relates to a piston integrated measuring system, which is characterized in that a sensor is adopted to respectively fix on the both sides of a clamp apparatus, the sensor is connected with the analog quantity input ports of an intelligent data acquisition and a control device, the clamp apparatus is positioned on the motor rotator device, the control signal output ports of the intelligent data acquisition and the control device are connected with the motor rotator device, the output end of an impulse signal generator is connected with a button, and the button is connected with the signal input ports of the intelligent data acquisition and the control device; the intelligent data acquisition and the control device is connected with an industrial control computer; the invention realizes the integration of the piston detection automation and the statistical process control. The automatic detecting device can only be put in the assigned position by the on-site operator and the button is pressed; the piston is rotated, the sensor measures the data on time, on one hand, the data is provided for an operator though a high light brightness display, on the other hand, the database transferred to the computer realizes the statistical process control, and the invention is favorable of forming a quality management system of an enterprise.

Description

technical field [0001] The invention relates to a comprehensive measurement system for pistons, specifically a computer-aided detection system for piston sizes, which is suitable for detection of the outer diameter of pistons, can find the maximum and minimum values ​​of the diameter, and calculates the size according to the statistical rules of the size Change real-time alarm to realize the synthesis of piston size detection and statistical control. Background technique [0002] The precision required for piston measurement is high (up to 0.001mm). In the existing technology, the flow of the traditional piston outer circle measurement method is as follows: the operator puts the finished piston product at a designated position, and two centimeters are symmetrically fixed on both sides of the position. Sub-meter; rotate the piston, observe the reading changes of the dial indicator, and judge whether the piston meets the quality requirements based on experience. This kind of ...
