Description

Technical Field

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

[0002] Most of the hinges used for the workbench flaps on the market are hinge type, usually distributed on both sides of the workbench and bolted to connect the workbench and the base. This type of hinge is easy to fail due to rust and has low strength. For example, a Chinese patent document with publication number CN202491319U discloses a workbench of a bridge-type stone cutting machine, which is characterized by: including 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, and the upper and lower frames are connected by hinges. A hydraulic cylinder for driving the upper and lower frames to open and close is provided between the upper frame and the lower frame. When in use, the upper and lower frames are driven by two cylinders arranged between the upper and lower frames to flip through two hinges arranged on the upper and lower frames.

[0003] In the above scheme, both hinges are hinge-type hinges. Therefore, in daily use, hinge-type hinges are prone to failure due to rust, and hinge-type hinges have low strength. They are prone to become unstable, deviate or directly fail due to uneven force or external force. Utility Model Content

[0004] The purpose of the utility model is to provide a more stable workbench for a stone cutter.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0016] As a further improvement of the utility model, a mounting hole for the hinge shaft to pass through is formed on the side plate, and a screw hole extending radially along the mounting hole is opened on the side plate, and a locking bolt is arranged in the screw hole.

[0017] By adopting the above technical solution, when the hinge shaft passes through the mounting hole, the screw hole provided in the radial direction of the mounting hole can be used to lock the bolt, so that the hinge shaft can be more stably installed in the mounting hole.

[0018] As a further improvement of the present invention, the hinged member is welded and fixed on the loading platform.

[0019] By adopting the above technical solution, the hinged component can be fixed on the loading platform more stably.

[0020] As a further improvement of the present invention, the hinged seat also includes a bottom plate, the two side plates are vertically fixed on the bottom plate, and the bottom plate is locked and fixed to the base by fasteners.

[0021] By adopting the above technical solution, the two side panels can be vertically fixed on the bottom plate, which can make assembly more convenient. The bottom plate is locked and fixed on the base by fasteners, which can further increase the stability of the hinged seat.

[0022] As a further improvement of the utility model, the base includes two horizontal beams arranged in parallel and spaced apart and a plurality of longitudinal beams connected between the two horizontal beams, and the two hinged seats are fixedly arranged at a horizontal interval on the top of a horizontal beam.

[0023] By adopting the above technical solution, two parallel and spaced beams and multiple longitudinal beams connected between the two beams can make the structure of the base more stable, and two hinged seats are fixedly arranged at a horizontal interval on the top of a beam, which is more conducive to the assembly of the base and the loading platform.
