The utility model discloses a multi-size adaptive bearing fault diagnosis test bench, and belongs to the technical field of bearing diagnosis. The test bench comprises a workbench, the top of the workbench is fixedly connected with a supporting frame, one end of the supporting frame is provided with a control panel, and one side of the middle of the supporting frame is provided with a position sensor. A conveying belt is arranged at the top of the workbench, and a clamping mechanism is arranged at the bottom of the conveying belt. The clamping mechanism can clamp and fix the bearings with different sizes on the top of the conveying belt, is wide in adaptive range and is not limited by the sizes of the bearings. A rotating rod is inserted into a bearing inner ring, and a second electric push rod drives an extrusion block to push an insertion block, so that an extrusion plate extrudes and fixes the bearing inner ring, and rotation test and fault diagnosis are facilitated. And the output end of the motor is detachably connected with the rotating rod, so that the rotating rods with different sizes can be conveniently replaced to adapt to bearings with different inner ring diameters, and the adaptability and the disassembly convenience of the device are improved.

The invention provides a retractor for thyroid surgery, and relates to the field of retractors, the retractor comprises a frame body, a support frame plate is arranged in the frame body, and a skin negative pressure translation mechanism and a retractor mechanism are arranged on the support frame plate; the skin negative-pressure translation mechanism comprises a negative-pressure cylinder and a piston plate, the negative-pressure cylinder is connected to the supporting frame plate, the piston plate is movably connected into the negative-pressure cylinder in a sealed mode, the lower end of the piston plate is connected with an ejector rod, the lower end of the ejector rod is connected with a sealing body, the lower end of the sealing body is provided with a spring, the upper end of the spring is connected with the sealing body, and the lower end of the spring is connected with the negative-pressure cylinder; the drag hook mechanism comprises a drag hook and a rotating rod body, the drag hook is slidably connected to the supporting frame plate, one end of the rotating rod body is elastically and movably connected with the supporting frame plate, a pressing mechanism is arranged on the frame body, the pressing mechanism is rotationally pressed and attached to the other end of the rotating rod body, and the pneumatic telescopic rod firstly drives the skin negative pressure translation mechanism to adsorb the skin and then translates to open an incision. The drag hook mechanism extends into the incision under the assistance of the pressing mechanism, the integrated process is achieved, and double drag hook is conducted on the incision.

This application relates to the field of steel strip processing and discloses a continuous punching and waste collection device for steel strip, including a fixed frame and a rotating plate. A hydraulic rod is fixedly installed on the inner wall of the fixed frame, and a connecting frame is snapped into the inner wall of the fixed frame. Two electric push rods are rotatably connected to the bottom end of the rotating plate, and the bottom ends of the electric push rods are rotatably installed with the inner wall of the fixed frame. A storage box is movably connected to the surface of the fixed frame, and two handles are fixedly installed on the surface of the storage box. The center of the hydraulic rods is on the same straight line as the center of the fixed frame. This application, by installing the rotating plate on the inner wall of the fixed frame, rotatably connecting the bottom end of the rotating plate to the electric push rods, and installing the storage box on the surface of the fixed frame with two handles, facilitates the dumping of waste from the fixed frame into the storage box after the rotating plate is controlled to rotate by the electric push rods, thereby avoiding the problem of waste accumulation affecting the punching of the steel strip.
