Description

Technical Field

[0001] The utility model relates to the technical field of gantry milling machine processing equipment, in particular to a crane clamp for a gantry milling machine. Background Art

[0002] Gantry milling machine is a common large-scale CNC machine tool used to process flat surfaces, curved surfaces and complex contours of large workpieces. The main feature of the gantry milling machine is its gantry structure, in which the crossbeams and columns form a stable frame, the workpiece is placed on the workbench, and the tool controlled by the CNC system moves on three coordinate axes to complete the cutting process. Gantry milling machine is usually used to process large workpieces, such as molds, ship structures, wind power generation equipment, etc. For large or heavy workpieces, such as ship structures, wind power generation equipment, etc., the overhead crane fixture can provide sufficient support to prevent the workpiece from deformation or tilting due to its own weight, and ensure the processing accuracy. The use of overhead crane fixtures can reduce setup time. Once the fixture is correctly set up, the workpiece can be installed and unloaded quickly and accurately without the need for tedious fixture adjustments or repositioning of the workpiece, saving a lot of preparation time.

[0003] Traditional overhead crane clamps clamp the left and right sides of the workpiece with clamp arms and can also wrap the front and back sides of the workpiece with protective plates, thereby improving the stability and safety of the lifted workpiece, reducing risks in manual intervention and operation, and reducing the possibility of accidents.

[0004] However, the structure of traditional overhead crane clamps is usually relatively simple. When the angle needs to be adjusted during mold processing, it is usually necessary to frequently replace the clamps or readjust the position of the workpiece to adapt to the needs of different processing angles. The adjustable angle overhead crane clamp eliminates this need. Therefore, a overhead crane clamp for a gantry milling machine is proposed to solve the above problem. Utility Model Content
