Description

Technical Field

[0001] The utility model relates to the technical field of spring chucks, in particular to a spring chuck corrector structure. Background Art

[0002] The spring chuck, also known as the spring collet, is a locking device for clamping tools or workpieces. It is usually used in drilling and milling machines and machining centers. The spring chuck mainly clamps the workpiece through a three-petal or four-petal clamping head to perform processing operations on the workpiece. During long-term use, the inner hole position in the middle of the spring chuck is prone to wear. When the spring chuck is worn too much, it is necessary to correct the inside of the spring chuck through a correction structure to ensure the stability of the spring chuck in subsequent use.

[0003] The spring chuck corrector structure disclosed in the Chinese utility model patent application disclosure CN205057417U can well correct the spring chuck through the corrector. The corrected spring chuck can still be used for precision machining, extending the service life of the spring joint, saving resources and expenses. However, the corrector only limits the position of spring chucks of a single size, and is not convenient for stably clamping spring chucks of different sizes, thereby affecting the subsequent stability of the spring chuck.
