It is characterized in that a limiting turntable assembly is installed inside the frame. The limiting turntable assembly includes a layer board, an annular seat and a turntable arranged in sequence from bottom to top. Both sides inside the turntable are fixedly installed with strong magnetic blocks. The lower part of the turntable is annularly distributed with limiting columns. The upper ends of the limiting columns are fixedly arranged with the turntable. A cavity opened at the lower end of each limiting column is embedded with a ball, and the bottom of the ball is arranged to roll on the upper part of the layer board. The upper part of the layer board is integrally provided with a limiting protrusion, and the middle part of the lower side of the layer board is fixedly installed with a motor.

[0015] The present utility model will be specifically described below with reference to the accompanying drawings. As shown in the Figure 1 accompanying drawings, a uniform-speed processing screw polishing machine includes a frame 1. An upper side inside the frame 1 is fixedly installed with a polishing barrel 2. An upper part of the polishing barrel 2 is detachably installed with a barrel cover 3. The polishing barrel 2 is a barrel with a motor stirring assembly. Inside the frame 1 is installed a limit turntable assembly 4.

[0016] In this embodiment, as shown in the Figure 2 accompanying drawings, the limit turntable assembly 4 includes a laminate 41, an annular seat 42, and a turntable 43 arranged in sequence from bottom to top. On both sides inside the turntable 43 are fixedly installed strong magnet blocks 44. At the lower part of the turntable 43 are annularly distributed limit posts 45. The upper ends of the limit posts 45 are fixedly arranged with the turntable 43. Inside a cavity opened at the lower end of each limit post 45 is embedded a ball 48. The bottom of the ball 48 is in rolling contact with the upper part of the laminate 41. Inside the annular seat 42 is opened a groove. An upper part of the laminate 41 is integrally provided with a limit projection 46. In the middle of the lower side of the laminate 41 is fixedly installed a motor 47. The laminate 41 and the turntable 43 separate the strong magnet blocks 44 and the motor 47, reducing the influence of the magnetic field of the strong magnet blocks 44 on the motor 47. When the turntable 43 rotates, the limit posts 45 and the balls 48 support the turntable 43, and the annular seat 42 and the limit projection 46 limit the limit posts 45 and the balls 48, making the rotation of the turntable 43 more stable.

[0017] In this embodiment, specifically, at a position corresponding to the annular seat 42 on the outside of each limit post 45 is detachably installed a projection, and the projection is slidably arranged in the groove.

[0018] In this embodiment, specifically, an output shaft of the motor 47 is fixedly installed with the turntable 43.

[0019] In this embodiment, specifically, the laminate 41 is fixedly installed inside the frame 1, and the turntable 43 is arranged at the lower part of the polishing barrel 2.

[0020] Working principle

[0021] In the present utility model, during polishing, the magnetic needles, the screws to be polished, and the polishing water are put into the polishing barrel 2. The motor 47 drives the turntable 43 and the strong magnetic block 44 to rotate, so that the magnetic needles in the polishing barrel 2 are forced to move and thus generate friction with the screws, realizing the function of polishing the screws.

[0022] Any technical solution using the technical solution of the present utility model, or any technical solution designed by those skilled in the art inspired by the technical solution of the present utility model and achieving the above technical effects shall fall within the protection scope of the present utility model.
