The utility model discloses the technical problem that will solve takes following technical scheme to realize:

an axial floating deburring mechanism comprises a rear shell, a front shell, an axial floating steel ball support, an expansion sleeve, a locking plate, a rear cover, a front cover and a deburring head, wherein the front shell is fixed with the rear shell, the rear cover covers the rear shell, the front cover covers the front shell, the deburring head is inserted into the front shell and the rear shell, two ends of the deburring head respectively extend out of the centers of the front cover and the rear cover, the expansion sleeve is positioned in the front shell and fixedly connected with the deburring head, the axial floating steel ball support is sleeved on the deburring head, a plurality of steel balls in contact with the inner side face of the front shell are mounted on the axial floating steel ball support, the axial floating steel ball support is fixed with the expansion sleeve through the locking plate, an air chamber is arranged in the rear shell, and a floating piston in sliding seal with the inner wall of the air chamber is arranged in the air chamber, the front end of the floating piston is in contact with the axial floating steel ball support, and the rear shell is further provided with an air pipe joint communicated with the bottom of the air chamber.

Through adopting above-mentioned technical scheme, on installing knife rest or robot arm with back casing, be connected to gas station or compressed gas jar with the trachea joint, the steel ball support that floats radially carries on spacingly avoiding radial swing when the burring to the burring head in the footpath.

When the floating steel ball support is in a standby state, compressed gas is conducted into the air chamber in the rear shell through the air pipe joint, so that the floating piston floats, and the axial floating steel ball support moves axially.

In the working state, when the deburring head chamfers the burrs of the die-casting product, the deburring head receives rightward axial force, so that the deburring head and the axial floating steel ball support move rightwards under the action of the steel ball, the axial floating steel ball support is in contact with the floating piston and moves rightwards, in the process, gas between the air chamber bottom and the floating piston is compressed to provide leftward thrust, when the chamfers are completed, the deburring head is gradually reduced by the rightward axial force, the deburring head is reset under the action of the floating piston, in the actual processing process, the deburring head always moves in a reciprocating mode along the axial direction, and the gas between the air chamber bottom and the floating piston is switched between the compression state and the release state.

As a preferred example, a rubber sheath is further fixed between the front cover and the deburring head.

As a preferred example, a rubber sheath is further fixed between the rear cover and the deburring head.

As a preferred example, a seal ring is provided between the rear cover and the rear housing.

The utility model has the advantages that the problem of excessive cutting or missed cutting caused by the tolerance of the actual product in the deburring process of the robot can be reduced, and the problem of cutter breakage can be effectively avoided. The automatic production orderly and completely runs, the compensation effect of cutter abrasion can be achieved, and the robot programming time is greatly reduced. The air pressure can be adjusted to control the cutting force. The flexibility is completely realized.
