Embodiment 1

[0044] This embodiment provides an upper grinding disc for a disc ball mill. The lower surface of the upper grinding disc 1 is provided with a V-shaped groove 4 distributed along the circumferential direction near the outer edge. It is adapted to the upper surface of the lower grinding disc 2; the upper grinding disc 1 is used for connecting with a floating part and used as a floating grinding disc. The angle of the V-groove 4 is 90°. The V-shaped groove 4 is used to accommodate the microspheres. The size of the V-shaped groove 4 is set according to the diameter of the grinding microspheres. For example, the diameter of the microspheres that can be processed: 0.7mm~3mm, a symmetrical right-angle "V"-shaped groove is used, and three kinds of grooves are provided. The "V" grooves are: the microspheres with a diameter of 0.7mm correspond to a groove width of 1.12mm; the microspheres with a diameter of 2.0mm correspond to a groove width of 3.16mm, and the microspheres with a diame...

Embodiment 2

[0048] This embodiment provides an upper grinding part for a disc ball mill, including the upper grinding disc for a disc ball mill provided in Embodiment 1; and a floating part, which drives the upper grinding disc 1 to float up and down. The floating part includes an elastic piece and a pressure plate 6, one end of the elastic piece is connected with the pressure plate 6, the pressure plate is connected with the upper grinding disc 1 through the mounting piece, the elastic grinding pressure is applied through the elastic piece, and the elastic grinding pressure is applied by the pressure plate 6 and the mounting piece. Transfer to upper grinding disc 1. A load cell 7 is also provided between the pressing plate 6 and the mounting piece.

[0049] Regarding the specific structure of the elastic member, a structure with a spring as the main body can be adopted. like Figure 4 As shown, the mount includes an upper grinding disc mount 81 , ball splines 82 , an upper grinding dis...

Embodiment 3

[0052] This embodiment provides a planetary disc ball milling mechanism, including a lower grinding disc 2, and also includes an upper grinding disc provided in Embodiment 1 for a disc ball mill, or a disc ball mill provided in Embodiment 2. of the upper grinding part. The upper surface of the lower grinding disc 2 is adapted to fit the lower surface of the upper grinding disc 1 , and the upper surface of the lower grinding disc 2 is a smooth plane structure.

Abstract

The invention discloses an upper grinding disc for a disc ball mill. V-shaped grooves distributed in the circumferential direction are formed in the lower surface of the upper grinding disc, and the lower surface of the upper grinding disc is used for being matched with the upper surface of a lower grinding disc; and the upper grinding disc is used for being connected with a floating part and is used as a floating grinding disc. According to the upper grinding disc for the disc ball mill, the V-shaped grooves are formed in the upper grinding disc to limit and grind micro balls, and the upper grinding disc is adopted as the floating grinding disc, so that the limiting effect on the micro balls in the grinding process is weakened, it is guaranteed that the micro balls can effectively rotatereversely, the rolling randomness of ball bodies in the disc ball mill is favorably improved, uniform stress of the ball bodies at all angles is guaranteed, and the grinding quality is improved.

Description

technical field [0001] The invention relates to the technical field of polishing of spheres, in particular to a planetary disc type ball mill. Background technique [0002] Precision metal spheres play an irreplaceable role in many applications. For example, precision metal spheres are used in roundness meters, electrostatic gyroscopes, and bearings. For example, in laser fusion experiments, precision hollow metal spheres are often used as ignition sources. Target pill. Among the many grinding and polishing methods of precision metal spheres, disc ball mills have high grinding efficiency and fast loading speed compared with ultra-precision polishing methods such as four-axis polishing machines and plasma polishing, and can grind multiple spheres at the same time. advantages and are widely used. As a ball grinding and polishing equipment, disc polishing machine has experienced hundreds of years of development, and has extremely important applications in many fields such as ...
