Description

Technical Field

[0001] The utility model relates to a stone processing machine, in particular to a turning workbench for stone cutting. Background Art

[0002] At present, the bridge-type integrated machine frame flip workbench on the market generally adopts a double-cylinder structure. It is difficult for the double-cylinder mechanism to be completely synchronized when flipping the plate, which has a certain impact on the service life of the frame workbench, and the double-cylinder structure frame needs to reserve a large space to set the cylinder. For example, a Chinese patent document with publication number CN202491319U discloses a workbench of a bridge-type stone cutting machine, which is characterized in that it includes a support frame, a support shaft, a workbench panel, a positioning device and a driving device. The support frame includes a square upper frame and a lower frame, the upper and lower frames are connected by a hinge, and a hydraulic cylinder for driving the upper and lower frames to open and close is arranged between the upper frame and the lower frame. When in use, the two cylinders arranged between the upper and lower frames drive the upper and lower frames to flip through two hinges arranged on the upper and lower frames.

[0003] In the above solution, since it is difficult for the two cylinders and the two hinges to be completely synchronized during flipping, the workbench becomes unstable, which can easily affect the service life of the workbench during use. Utility Model Content
