The invention discloses a tool spindle device with multi-process isochronous tool change function, which belongs to the tool spindle device of a machining center. It includes the main shaft housing, input main shaft, output main shaft, bevel gear A and bevel gear B; the input main shaft slides and rotates on the main shaft housing, the output main shaft rotates on the main shaft housing, and the input bevel gear and the output bevel gear have the same The taper; the input spindle is equipped with a tool change cam, which controls the start and stop of the output spindle through the interaction between the tool change cam and the cam baffle; the bevel gear A and bevel gear B slide synchronously to change the rotation of the tool holder Speed, and then compress or extend the duration of different processes, so that different processes have equal standard duration. The invention is a tool spindle device with reasonable structure, which can adjust the duration of different processing procedures to the same duration, can replace the cutter without turning off the driving motor, and has higher processing efficiency.
Description
technical field [0001] The invention mainly relates to the field of tool spindle devices of machining centers, in particular to a tool spindle device with a multi-process isochronous tool changing function. Background technique [0002] As an important part of the machining center, the spindle device can drive the tool chuck to rotate to implement the machining of the parts. Its structural characteristics and working principle play a decisive role in the machining efficiency and machining quality of the parts. In the prior art, since different machining processes usually require different durations, the tool replacement durations of different processes in the multi-process machining process of the same part are different; in addition, the spindle device usually needs to turn off the drive motor for safety when changing the tool. After the tool is replaced, the motor needs to be started again. This frequent starting and closing of the motor will not only reduce the processing...
