Description

Technical Field

[0001] The utility model relates to the field of turning centers, in particular to a guide sleeve bracket structure of a turning center. Background Art

[0002] Turning center is the most widely used composite machining. It is based on lathe and further adds the functions of power milling, drilling, boring and sub-spindle, so that the processes that require secondary or tertiary machining of parts can be completed at one time on the turning center. Turning center is a composite turning machine that can greatly reduce the machining time and does not require re-clamping to achieve the requirements of improving machining accuracy. When cutting, the drill or tool rod of the turning center usually uses a guide sleeve to prevent deviation, so as to improve the size accuracy and position accuracy of the machined hole.

[0003] At present, the guide sleeve of the turning center needs to be supported by a bracket. The current bracket length is generally fixed. However, when the height is different, it is not convenient to support the guide sleeve and is not conducive to current use. Improvement is needed. For this reason, we propose a guide sleeve bracket structure for a turning center to solve the above problems. Utility Model Content
