Problems solved by technology

[0003] At present, conventional measurement uses measuring instruments (vernier calipers, outer micrometers, go-no-go gauges, calipers, vertical optical meters, roundness meters or three-coordinate measuring machines, etc.) to measure directly with the surface to be measured. The measuring force is generated between the instrument and the surface to be tested, and it is easy to leave scratches on the tested piece during the testing process, causing damage to it and affecting the measurement accuracy; and most of them are manually tested, and different testing personnel use different forces when holding the measuring

Example Embodiment

[0041] Example 1

[0042] A visual inspection system for large precision shaft parts is characterized in that it comprises a control module and a measurement module.

[0043] according to figure 1 , The control module includes: an industrial computer for sending instructions and receiving and processing data information; a motion control card for receiving instructions from an industrial computer and controlling the operation of the servo motor; and printing out information such as detection data and results , For later filing or other purposes of the printer; used to control the vision sensor module for data acquisition sensor controller and the electrical control system for the circuit connection of the entire system and operating buttons and indicators.

[0044] according to figure 2 , The measurement module includes: a vision sensor module for data collection of the axis to be measured 10; a grating ruler 9 for transmitting the distance moved by the vision sensor module to the i...

Example Embodiment

[0064] Example 2

[0065] Such as Figure 4 As shown, the structural principle of this embodiment is similar to that of embodiment 1, and the difference from embodiment 1 is that the transmitter 4 and receiver 5 in the visual inspection module consist of two sets of small transmitters: transmitter one 41 , Transmitter two 42 and two sets of small receivers: receiver one 51, receiver two 52, which are located on both sides of the axis to be measured 10 and distributed up and down, wherein the distance L between the two sets of small CCD sensors The standard shaft is calibrated. The diameter D of the shaft 10 to be measured in this embodiment can be calculated by the formula D=d1+d2+L, where d1 and d2 are measured by the visual inspection module.

Abstract

The invention discloses a visual inspection system for a large precision shaft part. A control module sends a control command to a measurement module. The measurement module controls a vision sensor module to detect a shaft to be detected. The emitter in the vision sensor module emits uniform and stable line structured light, and the receiver in the vision sensor module converts the received lightinformation into the surface data information of the shaft to be detected and transmits the information to an industrial control computer, and finally the industrial control computer receives and processes the information and displays and prints the detected results. Data acquisition and processing are completed by the industrial control computer, data transmission is automatically performed andthe measurement result can be obtained in real time. Besides, there is no direct contact with the part in the detection process so that the scratch phenomenon of the detected part caused by the contact in the measurement process can be avoided, the error caused by subjective factors or environmental factors in the manual detection can be avoided and thus the detection results are more objective.

Description

technical field [0001] The invention relates to the field of detection of mechanical parts, in particular to a visual detection system for large precision shaft parts. Background technique [0002] The development of the machinery manufacturing industry is inseparable from the improvement of the shape error measurement technology, and the measurement of coaxiality and straightness is an important part of the shape error measurement of shaft parts. Today, the precision and scale of industrial manufacturing are constantly improving. , People have higher and higher requirements for the measurement of shape and position error of shaft parts. [0003] At present, conventional measurement uses measuring instruments (vernier calipers, outer micrometers, go-no-go gauges, calipers, vertical optical meters, roundness meters or three-coordinate measuring machines, etc.) to measure directly with the surface to be measured. The measuring force is generated between the instrument and the...
