Its shape can be fan-shaped and is arranged at the bottom of the disk body 2. The magnetic force of the magnetic suction cup 41 can effectively fix the workpiece placed on the disk body 2 to prevent the workpiece from shifting or slipping during rotation and processing. The non-contact fixing method of magnetic fixing is adopted to avoid damage to the surface of the workpiece during the fixing process, further improve the processing quality of the workpiece surface, and at the same time increase the processing area and improve the processing efficiency.

[0024] refer to Figure 1-3A polishing and burring machine includes a frame 8, on which a rotating working disc and two polishing and burring mechanisms 9 are provided. The polishing and burring mechanisms 9 can perform polishing and burring treatment on a workpiece fixed on a disc body 2. The polishing and burring mechanisms 9 are prior art and will not be described in detail here. The two polishing and burring mechanisms 9 are symmetrically arranged, and a magnetic suction cup 41 is arranged directly below the polishing and burring mechanisms 9. The rotating seat 11 is connected to a driving mechanism 3, and the driving mechanism 3 is arranged close to the head of the magnetic suction cup 41. When the magnetic suction cup 41 fixes the workpiece, the driving mechanism 3 can provide sufficient rotational force to the disc body 2 to ensure the rotation of the disc body 2. The driving mechanism 3 includes a driving motor 31, active teeth and driven teeth 32, the driving motor 31 is fixed on the fixed platform 1, the active teeth are arranged on the output shaft of the driving motor 31, and the driven teeth 32 are sleeved on the rotating seat 11. The active teeth and the driven teeth 32 are meshed by at least one transmission tooth. The distance between the driving motor 31 and the driven teeth 32 can be extended by multiple transmission teeth, so that it is suitable for discs 2 with different diameters and the scope of use is improved; the disc 2 is coaxially arranged on the driven teeth 32, which can be fixed by welding or by bolts. When the driving motor 31 is started, the active teeth drive the driven teeth 32 to rotate through the meshing of multiple transmission teeth, thereby driving the disc 2 to rotate.

[0025] In some embodiments, a support mechanism 6 is further provided on the fixed platform 1, and the support mechanism 6 is provided between the fixed platform 1 and the disk body 2. The support mechanism 6 is symmetrically provided on both sides of the magnetic suction cup 41; the support mechanism 6 includes a support plate 61, and the support plate 61 can be a grooved plate. A support rod 62 is provided on the support plate 61. The support plate 61 and the support rod 62 form a stable support structure. The top circumferential surface of the support rod 62 is tangent to the bottom surface of the disk body 2, which can provide additional support force when the magnetic suction cup 41 fixes the workpiece, and ensure the stability of the disk body 2 when it rotates. The support mechanism 6 can also be arranged at a desired position according to actual application conditions. The support mechanism 6 also includes auxiliary support wheels 63. At least four auxiliary support wheels 63 are symmetrically provided on both sides of the driving mechanism 3 and the demagnetizing mechanism 5. The auxiliary support wheels 63 can provide additional support points and reduce the friction force when the disk body 2 rotates, thereby further improving the stability and safety of the polishing and burr removal machine.

[0026] In some embodiments, a demagnetization mechanism 5 is further provided on the fixed table 1, and the demagnetization mechanism 5 includes a demagnetization plate 51. The demagnetization plate 51 is arranged at the bottom of the disk body 2 and is arranged close to the tail of the magnetic suction cup 41. A demagnetization area can be formed above the demagnetization plate 51, and the workpiece passing through the area can be demagnetized, which is convenient for taking the workpiece after processing and avoids additional demagnetization treatment of the workpiece after processing, thereby further improving work efficiency; the demagnetization mechanism 5 can be a platform demagnetization machine, which is a prior art and will not be repeated here.

[0027] A protective device 7 is provided on the fixed table 1, and the protective device 7 includes an inner ring 71 and an outer ring 72. The inner ring 71 is coaxially arranged outside the rotating seat 11, and the outer ring 72 is coaxially arranged outside the inner ring 71. A supporting mechanism 6 is provided between the inner ring 71 and the outer ring 72. The inner ring 71, the outer ring 72 and the supporting mechanism 6 form a connected whole, which can improve the supporting strength and improve the stability of the disc body 2 during rotation; at the same time, it can prevent debris and other materials in the processing process from entering the bottom of the disc body 2 and affecting the normal operation of the polishing and burr removal machine.

[0028] In some embodiments, there may be two magnetic suction cups 41, which correspond to the positions of two polishing and deburring mechanisms 9 respectively. When the workpiece is rotated to the position of the polishing and deburring mechanism 9, it can be stably fixed by the magnetic suction cups 41, thereby achieving high-quality polishing and deburring processing; at the same time, a support rod 62 is also arranged between the two magnetic suction cups 41, and an auxiliary support wheel 63 is provided on the magnetic suction cup 41, which can magnetically fix the workpiece to be processed on the disc body 2, provide additional support points, and further enhance the stability of the polishing and deburring machine.

[0029] The specific working principle is as follows:

[0030] When the polishing and deburring machine is working, first, the workpiece to be processed is placed on the disc body 2 at the discharge station, the driving mechanism 3, the fixing part 4 and the demagnetizing mechanism 5 are started, and the driving motor 31 drives the disc body 2 to rotate on the rotating seat 11 through the active gear and the driven gear 32, and the workpiece rotates on the disc body 2 accordingly. When the workpiece rotates to above the magnetic suction cup 41, the workpiece is adsorbed and fixed on the disc body 2 under the action of the magnetic force, and the polishing and deburring mechanism 9 corresponding to the magnetic suction cup 41 starts to polish and deburr the workpiece; after the polishing and deburring mechanism 9 has processed a workpiece, the disc body 2 continues to rotate to the demagnetization area above the demagnetization mechanism, and the workpiece is demagnetized by the demagnetization plate 51. The workpiece rotates one circle with the disc body 2 and rotates back to the discharge station to complete the polishing, deburring and demagnetization of one side of the workpiece, and the workpiece is removed from the disc body 2 or turned over to perform polishing and deburring on the next side.

[0031] Embodiment 1:

[0032] refer to Figure 4-5At least three guide grooves 21 are provided on the disk body 2. The three guide grooves 21 are annularly distributed on the top surface of the disk body 2. The depth of the guide grooves 21 gradually increases along the rotation direction of the disk body 2 and away from the center direction of the disk body 2. During the processing of the workpiece, the debris on the surface of the workpiece is separated from the workpiece and falls on the disk body 2. Due to the action of the guide grooves 21, distribution lines of different magnetic strengths are formed on the disk body 2. Under the dual action of rotation and magnetic force, the debris is guided to gather in the guide grooves 21, thereby preventing the debris from accumulating on the surface of the rotating working disk and contacting and damaging the surface of the workpiece in subsequent processing, thereby improving the processing quality and facilitating the cleaning of debris and other materials in the later stage, thereby reducing the scratches on the surface of the rotating working disk by the debris during the cleaning process. The guide grooves 21 can be arc grooves, which can increase the accommodating space of the guide grooves 21. The arc direction of the guide grooves 21 can be the same as the rotation direction of the disk body 2, thereby facilitating the throwing out of the debris during the rotation of the disk body 2.
