Double cam linkage work-table exchange set

Abstract

The present invention discloses a double-cam linkage worktable exchange device. The structure is that a cam shaft (14) connected with a power device is supported on a bracket (6); the cam shaft (14) is fixed with an elevating cam (4); one end of an elevating rod (1) matched with the elevating cam (4) is axially connected with the bracket (6) and the other end of an elevating lever (1) is arranged below a worktable round disc (10) which is fixedly connected with a rotating shaft (7); a rotating shaft sleeve (8) connected with the axial slide key of the rotating shaft (7) is sheathed outside the rotating shaft (7); the rotating shaft sleeve (8) is provided with a rotating idler wheel (9) which is matched with a rotating cam (5) arranged on the cam shaft (14). The present invention ensures that the lifting, the rotating and the falling of the worktable of the horizontal processing center are driven by a power mechanism and achieves the linkage in the whole process. Each motion is mutually and accurately matched with each other and the exchange process is rapid, safe, flexible and reliable, thus reducing the processing cost of the workpiece. The double-cam linkage worktable exchange device of the present invention is simple in structure and small in occupied space.

Description

Double-cam linkage table exchange device technical field The invention relates to a worktable exchanging device on mechanical processing equipment, in particular to a double-cam linkage workbench exchanging device for a horizontal machining center. Background technique The workbench on the horizontal machining center needs to have the exchange action of lifting and rotating, which is mainly completed by two driving mechanisms, one is a lifting mechanism and the other is a rotating mechanism. The lifting mechanism that controls the worktable is driven by a hydraulic cylinder connected to the hydraulic control device. The rotation of the worktable after it is lifted can be driven by a cam driven by a geared motor or driven by a hydraulic rotary cylinder. The whole action process can be divided into three independent steps: workbench lifting, workbench rotation, and workbench drop, which cannot be linked. From the working process, it can be seen that the position needs to be ...

Problems solved by technology

The whole action process can be divided into three independent steps: workbench lifting, workbench rotation, and workbench drop, which cannot be linked. From the working process, it can be seen that the position needs to be detected at each step in the whole process of workbench exchange. This makes the exchange time of the worktable longer, and at the same time, the movement process is unreliable, and it is easy to cause inaccurate mutual actions.
