Technical Field

[0001] The invention relates to the technical field of spot inspection equipment, and in particular to a DCS intelligent spot inspection instrument and a use method thereof. Background Art

[0002] The inspection instrument can collect a variety of equipment operation data. For example, for rotating machinery, its vibration data (including vibration acceleration, speed, displacement and other parameters) can be collected. For large motors in factories, the inspection instrument can accurately measure the vibration of the motor during operation through sensors installed on the motor housing. These data help to determine whether the motor bearings are worn, whether the rotor is balanced, and other issues. It can also collect temperature data and then determine whether the equipment is normal. The existing inspection instrument is small in size and easy to carry. It is suitable for mobile inspection between different equipment, that is, to detect various parameters of the equipment to ensure the normal operation of the equipment. However, the existing inspection instrument cannot realize the inspection of existing gears. For example: after the production of the gear, whether it meets the production specifications, or the gear of a certain equipment is replaced, and whether the replacement gear meets the use requirements of the original equipment, whether the gear diameter, number of teeth, pitch, whether the teeth are worn, whether the meshing transmission is normal, and whether the meshing transmission has high friction and high temperature, etc., is particularly important.

The first camera images the side walls of the teeth and the inner walls of the pitch grooves, the second camera detects the upper and lower walls of the teeth and the upper and lower walls of the gear as a whole, and the third camera images the meshing state of the gears; this is like observing a complex object from different perspectives. The image information from various angles complements each other, which helps to more accurately detect possible wear, defects and other problems on the gear surface.

[0014] 3. The temperature sensor detects the temperature of the gear after high-speed rotation. This parameter is very important for judging the working condition of the gear. For example, when the gear is excessively worn or does not fit well, the temperature will often rise due to increased friction. Temperature detection can provide additional basis for judging whether the gears are matched and whether there is wear, thereby improving the accuracy of the test results.

[0015] 4. The DCS system is used for integrated control, and the entire detection process can be automated; the DCS system can coordinate the work of the first drive component, the second drive component, various sensors and cameras in the detection structure, etc., without excessive human intervention, greatly improving the detection efficiency.

[0016] 5. The first drive assembly and the second drive assembly can fix the gears to be inspected with shaft holes of different diameters; this means that the inspection system can be applied to the inspection of gears of various specifications, and there is no need to equip different inspection equipment for gears with shaft holes of different diameters, thereby improving the versatility of the equipment and the flexibility of inspection.

[0017] 6. By adjusting the orientation of the second drive assembly relative to the first drive assembly, the relative engagement of the spur gear or the helical gear can be distinguished for detection of different gears. BRIEF DESCRIPTION OF THE DRAWINGS

At this time, the infrared detector 655 and the second camera 656 are both located above the gear to be tested, and the second camera 656 can be used to perform imaging detection on the upper wall surface of the gear as the slide arm 64 moves forward and backward, or the third motor 652 can be used to drive the second camera 656 to flip and descend to the bottom of the gear as the cross-shaped slide rail 61 is used to detect the lower wall surface of the gear; during the detection, the fourth motor 662 in the third base 661 of the second detection component 66 is driven to drive the swing arm 663 to flip a certain angle, so that the swing arm 663 moves from above the gear to be tested to the gear to be tested, so that the third camera 664 is located above the engagement portion of the two gears, and the engagement rotation is imaged and detected; The second flip frame 54 can also be flipped on the first flip frame 53 to adjust the second drive assembly 57 to be vertical relative to the first drive assembly 44, so as to realize the meshing transmission detection of the two helical gears.

[0031] After imaging and detecting each part, the gear rotation speed can be increased. After a certain rotation speed, the temperature of the gear under test is detected by the temperature sensor 657 to check whether the temperature is too high, so as to judge whether the gear is normally used, whether there are defects in the teeth and tooth surfaces, and whether the bite is in place, thus forming a multi-data inspection.
