Clamping system and clamping method for large similar cylindrical workpieces

Abstract

The invention provides a clamping system for large similar cylindrical workpieces. The clamping system comprises at least two workpiece clamping devices; the workpiece clamping devices comprise first fixture bodies with semicircular structures and second fixture bodies; the first fixture bodies and the second fixture bodies are relatively connected to form a complete ring structure; and along the outer edge of the ring structure, transmission teeth engaged with external gears are arranged on the edges of the same side surfaces of the first fixture bodies and the second fixture bodies. The clamping system further comprises a bearing platform, and support bases arranged on the bearing platform in parallel; and a rotary driving device is arranged on one support base, and comprises a rotary driving mechanism and a driving gear connected with an output shaft end of the rotary driving mechanism. The invention further provides a clamping method for the large similar cylindrical workpieces. The clamping system has the advantages of safety, reliability, convenience in operation and high adaptability.

[0002] With the rapid development of science and industry technology, industrial manufacturing technology has made revolutionary breakthroughs, and the performance of corresponding processing and manufacturing, testing, experiment and other equipment has become stronger and stronger, but the clamping process of supporting workpieces or parts has not Adaptive progress has been made. With the implementation of various large-scale projects, the demand for clamping, processing, testing, moving, and fixing of large parts and components has become increasingly prominent. The traditional workpiece clamping method is not efficient and inconvenient to operate. Difficult to meet requirements

For example, when the entire large cylindrical workpiece is clamped, fixed, moved, hoisted, and integrally rotated, there are many problems: inconvenient operation, poor flexibility, lack of safety, poor precision, high cost, and low efficiency; some clamping devices It is suitable for the clamping of cylindrical workpieces with regular shapes. It can be clamped by trapping the workpieces at both ends respectively; but in the actual operation process, due to the large volume and weight of the workpieces, the process of inserting them is not easy, especially the workpieces When there are special-shaped structures such as "wings" locally, it hinders the clamping operation of the workpiece; and during the clamping operation, it is easy to cause damage to the surface of the workpiece; in order to solve this problem, it is necessary to conduct in-depth research
