[0018] The following is further illustrated in combination with specific embodiments, referring to Figures 1-4 The utility model discloses a burr removing device for brake, including magnetic rotary table 1 and placing on the container 2 of magnetic rotary table 1, the container 2 is used to put workpiece 8, and the container 2 is equipped with solvent 4 and magnetic medium 5 in it;The middle part of container 2 is provided with stirring screw rod 3, and solvent 4 and magnetic medium 5 are rotated in container 2 by magnetic rotary table 1 and stirring screw rod 3. Figure 4 The brake disc workpiece 8 in the container 2 is immersed in the container 2 and the magnetic medium 5 and contacts the bottom of the container 2, the magnetic field generated by the energization of the magnetic rotary table 1 will exert magnetic force on the surrounding magnetic medium 5, the magnetic medium 5 will be magnetized by the magnetic field, and then be attracted and driven by the magnetic force. Since the magnetic field is rotating continuously, the magnetic medium 5 will start to rotate in the rotating direction of the magnetic field, and the magnetic medium 5 will rotate in the container 2, and through the rapid rotating movement on the surface of the brake disc and the grinding work, the high-efficiency deburring, surface polishing, cleaning and grinding effects are achieved. In addition, the rotating direction of the stirring screw rod 3 is the same as the rotating direction of the magnetic medium 5, and the stirring screw rod 3 can lift the solvent 4 and the magnetic medium 5 from the bottom, so that the magnetic medium 5 can fully contact and polish the surface of the spline hole, making the burr removal more clean and complete.

[0019] As Figure 1As shown, the bottom of the container 2 in the embodiment is provided with a limiting socket 21, and the magnetic rotary table 1 is provided with a limiting column 11 which is adapted to be clamped into the limiting socket 21; specifically, when the container 2 is placed on the magnetic rotary table 1, the bottom limiting socket 21 is clamped on the limiting column 11 to be fixed, and the container 2 can be detached from the magnetic rotary table 1, so as to facilitate pouring of the solvent 4 or recycling of the polished metal powder.

[0020] As shown in the drawings, Figure 1 and Figure 2 As shown, the lower end of the stirring screw 3 in the embodiment penetrates through the bottom of the container 2, and the lower end of the stirring screw 3 is provided with a connecting head 31; the magnetic rotary table 1 is provided with a motor 7, and one end of the motor 7 is connected with a docking seat 6 which is adapted to the connecting head 31; specifically, in order to facilitate the mounting and dismounting of the container 2 and the magnetic rotary table 1, when the container 2 is placed vertically, the connecting head 31 can be automatically aligned and connected into the docking seat 6, so that the motor 7 can drive the stirring screw 3 to rotate.

[0021] As shown in the drawings, Figure 1 and Figure 3 As shown, the bottom of the container 2 in some embodiments is provided with a plurality of cushion blocks 22 for lifting the workpiece 8; specifically, in order to avoid that the brake disc is too tightly attached to the bottom of the container 2, which is not conducive to the flow of the solvent 4 and the magnetic medium 5, and the surface of the brake disc workpiece 8 is fully exposed, the overall burr polishing effect is better.

[0022] Optionally, the cushion block 22 is a semicircular arc structure, and a plurality of cushion blocks 22 are supported on the outer edge of the workpiece 8.

[0023] In order to make the solvent 4 and the magnetic medium 5 have a longer stroke to cover the brake disc spline inner hole from the bottom, the length of the stirring screw 3 is designed to be higher than the height of the workpiece 8.

[0024] It is worth mentioning that the magnetic medium 5 adopts iron filings or stainless steel needles.

[0025] In order to avoid the influence of the magnetic field of the magnetic rotary table 1 on the container 2, the container 2 is made of plastic material.
