The utility model relates to an ore grinding machine with specification-adjustable nano ceramic balls, which belongs to the technical field of ore grinding and comprises a grinding bin, a top cover detachably connected to the top of the grinding bin, a feed port fixedly communicated with the top of the top cover and a discharge pipe fixedly communicated with the bottom of the grinding bin. A self-adaptive grinding mechanism extending into the top cover is arranged on the upper surface of the top cover, and a cooling mechanism extending out of the grinding bin is arranged on the upper surface of the top cover. According to the ore grinding machine capable of adjusting the specifications of the nano ceramic balls, when a double-shaft motor is started, a main bevel gear and an auxiliary bevel gear are driven to be in transmission fit, and under the elastic force action of a reset spring, a sliding sleeve slides on a transmission shaft to drive a supporting rod and a movable plate to be expanded or contracted, so that the specifications of the nano ceramic balls are adjusted; and through centrifugal force and impact force generated by rotation, the ball bodies of the nano ceramic balls achieve the optimal grinding effect in the grinding bin, and the advantage of high grinding efficiency is achieved.

This utility model discloses a steel ball size sorting machine, including an outer cover, inside which a sorting rod assembly is fixed. The sorting rod assembly is provided with sorting grooves, the inner diameter of which varies from small to large, and the sorting rod assembly is inclined downwards. Below the sorting rod assembly is a ball receiving plate, which is provided with two partitions that divide the ball receiving plate into three ball receiving spaces. The two partitions can move along the ball receiving plate to change the size of the three ball receiving spaces. An inclined plate is also fixed to the outer cover, with two outer channels corresponding to the two outer ball receiving spaces respectively. The intermediate channel formed between the two outer channels corresponds to the middle ball receiving space. This utility model can change the size and position of the ball receiving spaces, so that the limited outlet channels can accommodate steel balls of different diameters, resulting in high utilization of the outlet channels and a small footprint.

The utility model relates to the technical field of bearing steel ball machining, in particular to a circulating grinding device for bearing steel ball machining. According to the technical scheme, the circulating grinding device for bearing steel ball machining comprises a machine shell, a motor, a grinding disc and the like, the machine shell is placed on the ground, the motor is fixedly connected to the bottom of the machine shell, an output shaft of the motor penetrates into the machine shell to be fixedly connected with the grinding disc, and the grinding disc is rotationally connected with the machine shell. The motor is started to drive the grinding disc to rotate at a high speed so as to grind steel balls, if the steel balls need to be ground according to different sizes, the hand wheel is rotated to enable the screw rod to rotate to drive the extrusion disc to move up and down, and the distance between the extrusion disc and the grinding disc can be adjusted by observing the graduated scale. The grinding requirements of steel balls with different sizes can be quickly and accurately met, the problem that the product quality is affected due to too large or too small pressure is solved, and therefore the quality and consistency of final products are improved.

This utility model relates to the technical field of bearing ball production equipment, and in particular to a multi-stage air-separated adaptive sorting device for bearing balls, comprising a main pipe, a collection hopper, a secondary pipe, and a size adjustment component; the collection hopper is connected above the beginning of the main pipe; the beginning of the secondary pipe is connected to the middle of the main pipe; the size adjustment component is located at the connection between the main pipe and the secondary pipe, and is used to adjust the ball size threshold flowing into the secondary pipe; the end of the main pipe is provided with a branch pipe of the same diameter as the main pipe body; the end of the secondary pipe is provided with a side through hole; both the branch pipe and the side through hole are equipped with fans. This utility model can improve the sorting efficiency and stability of the balls.

This utility model relates to the field of ball-serving machine technology, specifically a ball-serving machine. The ball-serving machine includes a ball-serving device and a support frame. The ball-serving device is located on top of the support frame and includes a ball-serving tube and a driver. A ball wheel housing is provided on the bottom side of the ball-serving tube. A ball wheel is provided at the output end of the driver. The ball wheel is rotatably mounted inside the ball wheel housing, and its top extends into the ball-serving tube. A conversion plate for adapting to ball size is provided inside the ball-serving tube above the ball wheel. A connector is provided between the ball-serving device and the support frame. The angle between the ball-serving device and the connector is adjustable, and the angle between the connector and the support frame is also adjustable. The support frame allows for horizontal angle adjustment of the ball-serving device. This utility model has a reasonable structure. Through its modular structure, multi-level angle adjustment, and adaptive ball design, it significantly outperforms traditional single-function ball-serving machines in terms of versatility, stability, and operability, and has high market promotion value.
