Problems solved by technology

[0002] At present, most domestic factories use manual or hand-held pneumatic or electric tools for grinding, grinding, and filing in the process of removing burrs and flashes from metal parts, which will easily lead to an increase in the defective rate of products, and the processing efficiency is very low. After processing, there will be problems such as rough and uneven surface of the product. There are also electric or pneumatic tools installed by robots for automatic grinding. However, due to the rigidity of the mechanical arm and the inaccurate positioning, it is easy to break the knife or casting during the removal of irregular burrs. damaged condition

Embodiment 1

[0020] Such as figure 1 and figure 2 As shown, the floating spindle provided by this embodiment includes a coaxial installation housing 1, a spindle body 2 and an air pressure chamber 3. Inside the housing 1, the lower part is located in the air pressure chamber 3, the top of the installation housing 1 is provided with an end cover 14, and the installation housing 1 is provided with an angular contact joint bearing 4, and the angular contact joint bearing 4 is sleeved on the upper part of the main shaft body 2. An inner lining ring 12 is provided between the inner wall of the angular contact spherical plain bearing 4 and the outer wall of the main shaft body 2, and an outer lining ring 13 is provided between the outer wall of the angular contact spherical plain bearing 4 and the inner wall of the installation shell 1. The top of the angular contact spherical plain bearing 4 and the The bottom is respectively provided with a spindle limit lock ring 5, and the two spindle limi...

Embodiment 2

[0023] This embodiment is basically the same as Embodiment 1, except that the air inlet 7 is changed, and an air pressure regulating device is connected to the outside of the air inlet 7 through an air pipe, and the air pressure regulating device includes an air storage tank and an air pressure regulating valve. , the air inlet 7 is connected to the air storage tank through an air delivery pipe, and the air delivery pipe is provided with an air pressure regulating valve.

[0024] Working principle of the present invention: add compressed air into the air pressure chamber 3 from the air inlet 7 (the air pressure in the air pressure chamber 3 can be adjusted between 0.1-0.8Mpa), when the air pressure chamber 3 is filled with pressure gas, according to the principle of gas pressure, the air pressure The floating moving ring 8 in the chamber 3 will automatically move to the center of the air pressure chamber 3, the main shaft body 2 is set on the floating moving ring 8, the main sh...
