Workbench mechanism and square tube machining device with same

The invention provides a workbench mechanism and a square tube machining device with same. The workbench mechanism comprises a workbench main body and a transmission assembly; the workbench main bodyis used for containing a to-be-machined square tube; the workbench main body is connected with the transmission assembly so that the workbench main body can be driven to move; the transmission assembly comprises a transmission gear and a transmission rack matched with the transmission gear, and the workbench main body is connected with the transmission rack so that the workbench main body can moveunder the action of the transmission gear and the transmission rack. The workbench mechanism solves the problem that the length of the workbench mechanism in the prior art is relatively short. 本发明提供了种工作台机构及具有其的方通加工设备，工作台机构包括：工作台主体，工作台主体用于放置待加工的方通；传动组件，工作台主体与传动组件连接，以带动工作台主体移动；其中，传动组件包括传动齿轮和与传动齿轮相配合的传动齿条，工作台主体与传动齿条连接，以使工作台主体在传动齿轮和传动齿条的作用下移动。本发明的工作台机构解决了现有技术中的工作台机构长度较短的问题。
