Description

Technical Field

[0001] This utility model relates to the field of rotor testing technology, and in particular to an air compressor rotor testing device. Background Technology

[0002] In existing technologies, flaw detection and testing of screw air compressor rotors mainly employs magnetic particle testing or ultrasonic testing. Ultrasonic testing can detect extremely small defects inside the screw air compressor rotor, such as cracks, pores, and inclusions. Generally, it can detect defects at the millimeter level or even smaller, which is crucial for the early detection of potential safety hazards in the rotor. At the same time, the propagation time and reflection position of ultrasonic waves in the rotor can accurately determine the location, depth, and size of defects. This helps maintenance personnel accurately assess the condition of defects and provides a reliable basis for subsequent repair or replacement work.

[0003] Currently, air compressor rotor flaw detection typically uses a rotatable special fixture to clamp and fix the rotor shaft end, and a motor drives the fixture to rotate the rotor, which in turn scans surface defects with the detection probe. However, existing clamping devices are complex in structure and cumbersome in operation, requiring multiple manual adjustments to ensure that the rotor axis coincides with the center of rotation, resulting in long preparation time and low efficiency. Therefore, an air compressor rotor detection device is proposed to solve the above problems. Utility Model Content

The left shaft end of the rotor is supported by the second support seat 214. The first motor 202 is activated, and the output end of the first motor 202 drives the first synchronous wheel 203 to rotate. Through the synchronous belt 204, the second synchronous wheel 206 is driven to rotate, which in turn drives the first support wheel 205 and the second support wheel 207 to rotate synchronously, causing the rotor to rotate at a constant speed around its axis. The second motor 5 is started, and the output end of the second motor 5 drives the lead screw 6 to rotate. The lead screw 6 is threaded with the inner wall of the movable seat 7, so that the movable seat 7 slides left and right along the inner wall of the detection frame 4, which drives the detection probe 9 on the mounting frame 8 to continuously scan and detect the surface of the rotating rotor. When it is necessary to detect rotors of different lengths, the second hydraulic cylinder 305 is started. Its telescopic end pushes the adjusting seat 303 to slide along the guide rod 302 in the adjusting groove 301. The adjusting seat 303 drives the first support seat 201 to move horizontally, thereby adjusting the distance between the first support seat 201 and the second support seat 214 to achieve support and positioning of rotors of different lengths.
