Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a crossbeam of a numerical control machine tool. Background Art
[0002] The crossbeam of a CNC machine tool is an important part of the CNC machine tool that carries the weight. Its function is to support and transmit the load of the entire machine tool. The crossbeam needs to bear and transmit various loads, maintain the overall stability of the machine tool, and ensure that the machine tool does not vibrate excessively and deform during the processing, thereby ensuring accuracy and efficiency. In addition, the crossbeam must also transmit dynamic parameters such as processing force and torque to enable it to perform processing operations, and absorb the impact and vibration generated during the processing to minimize them.
[0003] The applicant searched the existing snap-in devices for automobile interior parts and found that the crossbeams of some existing CNC machine tools are bulky, inconvenient to install and disassemble, lack a convenient installation structure, and fail to reduce their own weight while meeting the needs of workpiece processing through a reasonable structure, which results in a high consumption of steel. A CNC gantry machine tool crossbeam disclosed in Chinese patent number CN220740149U includes a main body mechanism, a rotating mechanism and a limiting mechanism. The rotating mechanism is located at the outer end of the main body mechanism, and the limiting mechanism is located at the outer end of the main body mechanism. The main body mechanism includes a base plate, a support rod, a crossbeam mainboard, a long hole, a support seat one, a support seat two and a reinforcing rib.

The overall structure is simple. By setting the long hole inside the crossbeam mainboard, the device can ensure the horizontal displacement of the processing tool while reducing the steel usage of the device, making the device more energy-saving and environmentally friendly.
