Detailed Description

In order to make the technical problem solved by the present invention, the technical solution adopted by the present invention and the technical effect achieved by the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present invention are shown in the drawings.

As shown in fig. 2, the embodiment of the utility model provides an automatic burring equipment of hole keyway, include: the deburring machine comprises a power main shaft, a positioning disc 1, a grinding shaft 2, a brush connecting piece 3 and a deburring brush 4.

In this embodiment, the power spindle may directly adopt a rotating shaft of the numerically controlled lathe, or may adopt a rotating shaft driven by a motor.

And the output end of the power main shaft is provided with a positioning disc 1. The structure of the positioning plate 1 is shown in figure 3. The axis of positioning disk 1 is fixed connection axle 2 of polishing, specifically, positioning disk 1 and axle 2 of polishing pass through four spot welding. As shown in fig. 4, the end of the grinding shaft 2 is provided with a brush attachment 3; the end part of the brush connecting piece 3 is provided with a deburring brush 4; the deburring hairbrush 4 is axially vertical to the hairbrush connecting piece 3. The positioning disc 1, the grinding shaft 2 and the brush connecting piece 3 are coaxially arranged.
