Technical Field

[0001] The utility model relates to the technical field of a tool rest, in particular to a tool rest for lathe processing of shaft metal parts. Background Art

[0002] When turning shaft metal parts on a lathe, if the shaft metal parts are clamped at both ends and lack support in the middle, they will produce natural deflection due to gravity, and this deflection will be amplified by centrifugal force during the turning process, which can easily cause deformation and vibration, making it difficult to guarantee the size and accuracy of the workpiece. Therefore, it is necessary to add corresponding auxiliary tooling, that is, the tool rest, to the slide on the lathe.

[0003] According to the patent website, a tool rest for machining a slender shaft lathe (authorization announcement CN 213164122U) describes "a tool rest for machining a slender shaft lathe, comprising an L-shaped tool rest seat, the short plate of the tool rest seat being fixed horizontally on the lathe by bolts, a movable plate being slidably arranged on the long plate of the tool rest seat, a fixing mechanism being arranged between the movable plate and the tool rest seat, a support plate being fixed horizontally at the bottom of one side of the movable plate, a mounting plate being hinged at the top of the support plate, and a locking mechanism being arranged on the mounting plate, a groove being arranged at the top of the mounting plate, a pin being threadedly connected to the groove away from the hinged side, and a support mechanism for supporting a workpiece to be machined can be detachably connected to the end of the pin after passing through the groove."

However, in actual use, the device needs to be fixed by locking bolts, and the supporting structure matching the workpiece is threadedly connected to the pin shaft, and the model of the suitable shaft metal part needs to be constantly replaced, which can easily lead to more troublesome operation, increase the tediousness of the staff's work, and is not conducive to rapid cutting processing.
