The present disclosure provides an automatic chuck apparatus comprising a mechanical chuck, a mechanical chuck mounting bracket, a hydraulic motor, a lifting mechanism, a chuck key and a lifting cylinder. The mechanical chuck is mounted above the mechanical chuck mounting bracket. The hydraulic motor, the lifting mechanism and the lifting cylinder are mounted below the mechanical chuck mounting bracket. The hydraulic motor is configured to control the rotation of the chuck key, the lifting cylinder is configured to drive the chuck key to ascend or descend through the lifting mechanism, thereby the mechanical chuck is locked or loosened by the chuck key. The present disclosure further provides a grinding wheel cutting apparatus and a cutting method. In the present disclosure, the locking of the chuck is automatically controlled, thereby improving the working efficiency and ensuring sufficient locking force of the chuck.

The present disclosure provides a grinding wheel apparatus comprising a grinding wheel, a flange, a pull rod and a spindle. The grinding wheel is mounted on one side of the flange, and the other side of the flange is a tapered bucket, the tapered bucket has a buckle slot. The pull rod passes through the spindle, and a pull rod head of the pull rod is fixed to one end of the spindle, the tapered bucket is inserted into the spindle from the other end of the spindle, and the buckle slot is engaged with the T-shaped buckle of the pull rod in the spindle to fix the flange on which the grinding wheel is mounted to the other end of the spindle. The present disclosure further provides a grinding wheel cutting apparatus comprising the grinding wheel apparatus, and a cutting method using the grinding wheel cutting apparatus.

Grinding wheel apparatus, grinding wheel cutting apparatus and cutting method

A method for performing cardiology and endovascular interventional operations includes: Step 1, putting an artery sheath into a punctured artery; inserting a Pigtail catheter into a first end of the artery sheath, and advancing it to a left ventricle; injecting contrast into the Pigtail catheter to perform left ventricle angiography; and withdrawing the Pigtail catheter from the artery sheath. Step 2, inserting a guiding catheter into the first end of the artery sheath, and advancing it to the left ventricle. Step 3, advancing a myocardial biopsy forcep to a left ventricle endocardium through the guiding catheter to collect a piece of myocardium. Step 4, withdrawing the myocardial biopsy forcep from the guiding catheter, and preserving a myocardium specimen. Step 5, repeating steps 3 and 4 until collecting enough number of myocardium specimens. Step 6, withdrawing the guiding catheter from the artery sheath, and pulling the artery sheath out of the artery.

Methods and device for performing cardiology and endovascular interventional operations via radial artery or ulnar artery

The present disclosure provides a grinding wheel cutting apparatus comprising a first laser distance sensor, a master controller and a grinding wheel. The first laser distance sensor is communicatively coupled to the master controller. The laser distance sensor is configured to obtain an outer diameter of a rod workpiece. The master controller is configured to determine a segment length of a segment to be cut from the rod workpiece based on the outer diameter, a material density of the rod workpiece and a preset segment weight. The master controller is configured to perform a control to circularly cut the rod workpiece with the grinding wheel according to the segment length. The present disclosure further relates to a cutting method using the grinding wheel cutting apparatus.

Grinding wheel cutting apparatus and cutting method

A data processing method and apparatus, and a readable medium and an electronic device are provided. The method includes: collecting a facial image of a user by means of a terminal, and taking the collected facial image as a first facial image, displaying the first facial image in a user display area of a terminal screen; where the terminal screen displays a target object, collecting a sound signal of the user, and taking the collected sound signal as a target sound signal; and if the sound intensity of the target sound signal is within a first intensity range, switching a display state of the target object, and switching the first facial image in the user display area to a second facial image, wherein the second facial image is obtained on the basis of the first facial image.
