Description

Technical Field

[0002] A gantry machine tool is a large machine tool with a portal frame structure. It is mainly used for high-precision milling, drilling and other processing tasks. It is particularly suitable for processing large, heavy or complex workpieces. Gantry machine tools usually have five-axis linkage processing capabilities, which can achieve precision processing of complex parts. Gantry machine tools mainly include five-axis linkage vertical machining centers, five-axis linkage fixed-beam gantry machining centers, gantry milling machines and gantry wire-cutting machines.

[0003] In the existing technology, when a gantry wire cutting machine is processing large and small raw materials, it is often necessary to measure and position the raw materials. The positioning method of the traditional gantry wire cutting machine generally uses a laser interferometer length gauge or a spacing gauge to position the workpiece. However, since the gantry wire cutting machine is accompanied by coolant during processing, when the raw materials that require special processes (such as inclination processing of special-shaped parts) are wire-cut, the staff needs to adjust the inclination angle of the workpiece itself after the processing is completed. At this time, since the surface of the workpiece is contaminated with coolant during the processing, the laser of the laser interferometer length gauge will cause errors due to the refraction of the liquid surface. Then the staff needs to continuously cooperate with the laser interferometer length gauge to adjust the workpiece multiple times during the processing, which will affect its processing effect.

In this way, the size and weight of the workpiece have no effect on the load-bearing capacity of the entire machine tool when processing the workpiece, because in normal wire cutting, the larger and heavier the workpiece, the greater the load-bearing capacity of the machine tool, and the greater the impact on precision, because conventional wire cutting processes the workpiece by moving the worktable 1 (the core movement is the planar movement of the worktable 1 (X, Y axis) and the reciprocating / unidirectional movement of the electrode wire.

[0032] Working principle: Please refer to Figures 1-13As shown, by using a spacing adjustment component, the spacing between the multiple receiving heads 19 can be made to be away from each other, so that they can adapt to raw materials of different sizes. Then the staff can place the raw materials on the top of the multiple receiving heads 19, and then the staff can slide the multiple limit seats 3 to make them close to the outside of the raw materials, and then the raw materials can be clamped by the clamping component. After the above steps are completed, the staff can perform wire cutting operations on the raw materials. During this process, the staff can evacuate the interior of the air storage ring 30 to a vacuum state through an external negative pressure air pipe, and then the vacuum state of the interior of the multiple branch air pipes 28 can be independently controlled by multiple solenoid valves 34. Then the branch air pipe 28 will evacuate the interior of the second mounting tube 32 connected thereto to a vacuum state. At this time, under the action of air pressure, the second sealing push head 37 will drive the second connecting seat 70 The second connecting column 71 is moved and retracted into the interior of the second mounting tube 32, and then the movement of the second connecting column 71 will drive the adjusting push rod 27 to move, and then the inclined surface on the side of the adjusting push rod 27 will squeeze the adjusting frame 20, and then the second roller 22 will slide inside the adjusting plate 23 through the first roller 21 and the second roller 22. At the same time, since the slide grooves on both sides of the adjusting plate 23 are inclined, the adjusting plate 23 can drive the mounting column 18 and the receiving head 19 to move upward or downward, and the use height of multiple receiving heads 19 can be adjusted independently. At the same time, the clamping assembly can be adjusted in angle accordingly, which is convenient for the inclination processing of special-shaped parts. In this way, the angle adjustment and positioning of the special-shaped parts can be automatically controlled during the inclination processing, reducing the manual measurement, adjustment and positioning by the staff.
