Description

Technical Field

[0001] The utility model relates to the technical field of vertical lathes, in particular to a vertical tool rest adjustment structure of a vertical lathe and a machine tool. Background Art

[0002] Machine tools such as vertical lathes, vertical milling machines, and vertical machining centers require that the vertical tool holder be perpendicular to the work surface. In order to ensure the vertical requirement, the vertical tool holder and the crossbeam slide are usually designed as a relatively rotatable structure. The vertical tool holder is connected to the crossbeam slide through a center positioning shaft. The vertical tool holder can rotate relative to the crossbeam slide through the center positioning shaft. A fixed block is designed on the upper end face of the crossbeam slide, and two flat head screws are installed on both sides of the fixed block. Two fixed blocks are designed on the vertical tool holder. The flat head screw heads on the fixed blocks of the crossbeam slide are pressed against the fixed blocks of the vertical tool holder. By adjusting the length of the screws at both ends of the crossbeam slide fixed block, the vertical tool holder is adjusted to be perpendicular to the center line of the work table. After the adjustment meets the requirements, the screws between the crossbeam slide and the vertical tool holder are locked.

[0003] This type of adjustment and fixing structure has two disadvantages: on the one hand, when the tool holder is in a state of long-term continuous cutting or chip breaking cutting, the tightening screws on the crossbeam slide will generate impact force. Over time, the screws will loosen, and the tool holder will be offset when subjected to force, causing deviations in the machining accuracy of the machine tool, seriously affecting the reliability and stability of the machine tool; on the other hand, the adjustment mechanism is installed behind the vertical tool holder, and workers need to climb behind the vertical tool holder to operate for adjustment and maintenance, which is inconvenient to adjust and requires the cooperation of multiple people to complete the operation.
