Multi-station trepan boring machine

Abstract

The invention discloses a multi-station trepan boring machine, which comprises a clamping device, a cutting head and a drive device and also comprises a labyrinth waterproof disc and a clamping ring; the clamping device is used for clamping a to-be-processed workpiece and leading the to-be-processed workpiece to rotate; the drive device drives the cutting head to move along a certain straight line; the rear end of the cutting head is connected with a cooling liquid pipe; the cooling liquid pipe is connected with a water pump; the labyrinth waterproof disc comprises a first circular ring; a second circular ring is arranged in parallel with the first circular ring; the first circular ring is fixedly connected with the second circular ring through a third circular ring; the clamping ring is fixedly connected at the lower end of the second circular ring; a step surface and a boss are arranged on the clamping device; and the clamping ring of the labyrinth waterproof disc is tightly clamped in the boss and leans against the step surface. The multi-station trepan boring machine provided by the invention can effectively prevent cooling liquid from entering the clamping device to damage parts such as a bearing and the like in the clamping device, so that the service lives of parts such as the bearing and the like in the clamping device are not influenced.

Description

technical field [0001] The invention relates to a multi-station drilling machine, in particular to a multi-station drilling machine for processing brittle materials such as NdFeB and crystals. Background technique [0002] The multi-station trepanning machine is mainly used for precision trepanning of brittle and hard materials such as magnetic materials, semiconductor materials, and glass. The applicant applied for a multi-station trepanning machine in the early stage. The structure mainly includes a clamping device for clamping and rotating the workpiece to be processed, several cutting heads, and driving the cutting heads along the cutting direction. The driving mechanism of the movement, in order to prevent the whole machine from heating up too fast during operation, a coolant water pipe is connected to the rear end of the cutting head, and the coolant water pipe is connected to the water pump. During operation, the coolant is delivered by the water pump to achieve the c...
