Description

TECHNICAL FIELD

[0001] The utility model relates to equipment installation technical field especially relates to a coupling installation frock for high phase number encoder. BACKGROUND

[0002] Generally, the continuous casting slab surface defect automatic identification system adopts slab optical detection mode, belongs to non-contact detection, is less affected by high-temperature metal, has higher anti-interference ability, collects slab surface image through special light source and CCD camera, and adopts artificial intelligence to analyze and identify the image.

[0003] The high phase number encoder control CCD camera has many obvious advantages, can provide high-precision position and speed feedback signal, and can accurately control the triggering time of the camera according to the signal of the encoder when being used with the CCD camera.This means that the camera can expose when the object being photographed is in the best position, ensuring that the collected image is complete, clear and free from motion blur, providing high-quality materials for subsequent image analysis.In addition, due to its high-resolution characteristics, the high phase number encoder can realize sub-pixel level position detection.This enables the CCD camera to more accurately position the object when collecting images, accurately presents the subtle features of the object, and greatly improves the detail performance and detection accuracy of the image.

[0004] To collect the running accurate speed of the slab, a high phase number encoder needs to be installed on the buffer roller bed motor to collect the buffer roller bed motor speed, and according to the running speed of the slab returned by the encoder, the CCD camera is triggered to shoot the slab image.However, whether the high phase number encoder can be quickly and correctly installed and synchronized with the buffer roller bed motor rotor has always been a difficult problem for equipment installation.

[0005] Because the cage-shaped buffer roller bed motor is used on site, the installation space is limited when installing the high phase number encoder due to its structural characteristics, especially for some compactly designed cage-shaped buffer roller bed motors, which do not have ideal encoder installation positions, so it is necessary to additionally design an installation bracket or modify the buffer roller bed motor, increasing the complexity and cost of installation, and an inappropriate installation space layout may affect the installation accuracy of the encoder, and further affect the detection accuracy.In addition, when the high phase number encoder is connected with the shaft of the cage-shaped buffer roller bed motor, if the data needs to be accurately synchronized, the coaxiality of the two needs to be ensured.But the shaft of the cage-shaped buffer roller bed motor has certain vibration and movement during operation, if the rigidity of the connection between the encoder and the shaft of the buffer roller bed motor is insufficient or the coaxiality is not good, the detection error of the encoder will increase, and long-term operation may also cause wear of the encoder, affecting its performance and detection accuracy, and service life.

After the extension shaft and the shaft soft coupling are installed in the semicircle pipe column, the semicircle cover is used to close the opening of the semicircle pipe column, so as to prevent dust and other impurities from entering the semicircle pipe column and play a dustproof role.

[0015] Preferably, the recessed depth of the recessed step 41 on the surface of the first installation flange 4 is 3 mm, and the height of the annular convex 51 on the surface of the second installation flange 5 is 4 mm. The recessed step on the surface of the first installation flange and the annular convex on the surface of the second installation flange are matched with the shape of the installation surface of the high phase number encoder and the shape of the installation surface of the buffer roller way motor respectively, so as to realize the precise coupling between the high phase number encoder and the buffer roller way motor.

[0016] The rotating shaft of the buffer roller way motor is the center of the rotor of the buffer roller way motor, and is also the center of the rotating shaft of the high phase number encoder. The tool is welded with an extension shaft with a length of 60 mm and a diameter of 6 mm on the rotating shaft of the buffer roller way motor, and then a shaft soft coupling is used to couple the extension shaft with the rotating shaft of the high phase number encoder.

[0017] The tool simplifies the installation process of high-phase number encoders. The modular tool integrates the coupling structure of the buffer roller bed motor and the high-phase number encoder into a compact unit, occupying less space.

Compared with the traditional separate installation method, a large number of complex positioning and calibration steps are reduced. The installer does not need to repeatedly adjust the relative position between the buffer roller bed motor and the high-phase number encoder.
