Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a fine grinding equipment for silicon carbide ceramic balls. Background Technology

[0002] Silicon carbide ceramic balls are widely used in ceramic ball bearings, valves, gyroscopes, and measuring instruments due to their low density, small coefficient of thermal expansion, high hardness, high elastic modulus, high temperature resistance, and corrosion resistance. During the manufacturing process of silicon carbide ceramic balls, processing marks such as pressing and green turning are left. These marks need to be removed through grinding to make the ceramic ball surface uniform and smoother. A smoother, flatter surface helps reduce friction and wear during rotational or sliding contact, improving the durability and service life of the components. After semi-fine grinding, fine grinding is performed using diamond micron powder or lubricating grinding media. After fine grinding, the ceramic balls are cleaned and dried to remove grinding debris and coolant generated during the grinding process.

[0003] Traditional grinding equipment is a single unit, making it inconvenient to replace damaged parts and lacking flexibility in adding lubricant.

[0004] Therefore, it is particularly important to design a fine grinding device for silicon carbide ceramic balls to overcome the above-mentioned technical defects and improve the overall practicality. Utility Model Content

A filter frame 203 is located at the top of the grinding base 1. A drain pipe 204 is located inside the grinding base 1. Grinding discs are placed between the limiting frame and the limiting ring, and the position of the grinding discs is limited by the limiting frame and the limiting ring. The height of the placement plate 104 is adjusted by the first cylinder 103 so that it is close to the tray 108 below. The silicon carbide ceramic balls to be ground are placed in the slot on the placement plate 104. Then, the rotary motor 101 is started, which drives the entire grinding system to rotate through the fixed plate 102. At the same time, the motor at the bottom of the tray 108 is started, which makes the tray 108 and the silicon carbide ceramic balls on it start to rotate, increasing the grinding effect. The second cylinder 110 drives the connecting block 105 and the grinding disc 107 on it to move up and down to perform grinding. During the grinding process, the spring tube 2 provides lubricant between the grinding disc and the silicon carbide ceramic balls. At the same time, the peristaltic pump in the liquid storage tank 201 continuously circulates the lubricant to the grinding area to maintain a suitable grinding environment. The spring tube 2 can be adjusted at will. The mixture of grinding debris and lubricant flows into the drain pipe 204 through the filter frame 203 and is discharged. When the grinding disc needs to be replaced, the embedded block 106 and the connecting block 105 can be disassembled through the threaded rod.

[0025] The top of the placement tray 104 is equipped with a threaded cylinder. The placement tray 104 is threadedly connected to the output end of the first cylinder 103. The placement tray 104 has several equally spaced slots to facilitate replacement with placement trays of different slot sizes. The bottom of the tray 108 is equipped with a motor, and the output shaft of the motor is keyed to the tray 108 to facilitate rotation of the tray 108. The connecting block 105 has an embedded groove inside, and the embedded block 106 is adapted to the embedded groove. The connecting block 105 and the embedded block 106 have threaded grooves, and their positions are fixed by a threaded rod.

The tray 108 is provided with a limiting ring along its circumference. The limiting ring is provided with a protrusion. The limiting frame 109 is adapted to the limiting ring. The limiting frame 109 is provided with a clearance groove inside. In actual use, a grinding disc can be placed between the limiting frame and the limiting ring. The limiting frame and the limiting ring are used to limit the position of the grinding disc. The liquid storage tank 201 is provided with a peristaltic pump inside. The filter frame 203 is provided with a filter screen inside. The position of the filter screen is adapted to the drain pipe 204 to facilitate the discharge of lubricating fluid and debris.

[0026] The working process of this utility model is as follows: When using this silicon carbide ceramic ball fine grinding equipment, firstly, a grinding disc is placed between the limiting frame and the limiting ring. The limiting frame and the limiting ring limit the position of the grinding disc. The height of the placing plate 104 is adjusted by the first cylinder 103 so that it is close to the tray 108 below. The silicon carbide ceramic balls to be ground are placed in the slot on the placing plate 104. Then, the rotary motor 101 is started, which drives the entire grinding system to rotate through the fixed plate 102. At the same time, the motor at the bottom of the tray 108 is started, causing the tray 108 and the silicon carbide ceramic balls on it to rotate. The first rotation increases the grinding effect. The second cylinder 110 drives the connecting block 105 and the grinding disc 107 on it to move up and down for grinding. During the grinding process, the spring tube 2 provides lubricant between the grinding disc and the silicon carbide ceramic ball. At the same time, the peristaltic pump in the liquid storage tank 201 continuously circulates the lubricant to the grinding area to maintain a suitable grinding environment. The spring tube 2 can be adjusted at will. The mixture of grinding debris and lubricant flows into the drain pipe 204 through the filter frame 203 and is discharged. When the grinding disc needs to be replaced, the embedded block 106 and the connecting block 105 can be disassembled through the threaded rod.
