Description

Technical Field

[0001] This utility model relates to the field of machine tool mechanics, and in particular to a stable CNC machine tool crossbeam. Background Technology

[0002] In the machining process of CNC machine tools, the crossbeam is one of the key components, and its stability directly affects the machining accuracy and efficiency. At present, most machine tool crossbeams on the market are made of one-piece casting material. They are made by pouring molten metal into a pre-made mold during the manufacturing process. The material is generally cast iron or cast aluminum alloy. Therefore, a stable CNC machine tool crossbeam is particularly needed.

[0003] However, the existing CNC machine tool crossbeams are prone to deformation when subjected to external forces such as cutting forces due to their large span, resulting in a decrease in machining accuracy. With vibration during the machining process, the stability of the crossbeam is also affected, which in turn affects the machining quality. The lack of a transmission screw reduces the stability of the crossbeam, making it prone to tilting and resulting in poor stability, which in turn causes data deviations when machining products. Utility Model Content

These problems include the large span of the existing CNC machine tool crossbeam, which makes it prone to deformation under external forces such as cutting forces, leading to decreased machining accuracy. Furthermore, vibrations during machining also affect the stability of the crossbeam, thus impacting machining quality. The lack of a transmission screw further reduces the stability of the crossbeam, making it prone to tilting and resulting in poor stability, which in turn causes data deviations during product processing.

At this point, the operator places the product to be processed onto the operating base plate 3. The operator then adjusts the height of the crossbeam body 19 according to the shape and size of the product. Simultaneously, the operator starts two sets of motors 12, driving the transmission screw 13 to rotate, thereby moving the sliding seat 16 and causing the crossbeam body 19 on the sliding seat 16 to move. At the same time, the operator starts motor 20, driving the transmission screw... The second lever 21 rotates, thereby driving the sliding block 23 to move. When it moves to directly above the product to be processed, it stops, so that the cylinder 28 is on the product to be processed and the product is processed. After processing is completed, the operator starts the second motor 20 again, causing the sliding block 23 to move again, so that the cylinder 28 is away from the processed product. Finally, the operator starts the second motor 20 again to move the sliding block 23 away from the processed product. At this time, the operator can take out the product. The stability of the machine tool crossbeam body 19 is enhanced by the setting of the first transmission screw 13 and the second transmission screw 21 with the slide rail 15 and the guide rail 18.
