[0015] As a further solution of the utility model: a water tank is installed on the top of the tool changing magazine, and the water tank is connected to the spray rack through a water pipe, and a water pump is also installed on the water pipe.

[0016] By adopting the above technical solution, when in use, the water in the water pipe is transported to the spray rack through the water pump to achieve a convenient flushing effect.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the tool changing mechanism of the vertical machining center capable of protecting the tool head is

[0018] A traverse frame, a spray frame, a cleaning roller and a heater are provided.
