Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing and processing technology, and in particular to a surface grinder with a cooling function. Background Technology
[0002] A surface grinder with cooling function is a machine tool used for precision surface machining of metal workpieces. It is specially designed with a cooling system to manage the heat generated during the grinding process. During grinding operations, the high-speed rotating grinding wheel comes into contact with the workpiece surface, generating a large amount of heat. This can not only cause burns to the workpiece surface, alter material properties, or cause dimensional changes, but may also shorten the service life of the grinding wheel.
[0003] In modern manufacturing, surface grinders are one of the most important pieces of equipment for precision machining. They use high-speed rotating grinding wheels to grind the surface of workpieces to achieve the required dimensional accuracy and surface finish. However, existing surface grinders face a significant problem during long-term continuous operation: the continuous friction between the grinding wheel and the workpiece causes the surface temperature of the workpiece to rise, leading to thermal deformation. This heat generated by friction not only affects the shape accuracy of the workpiece but may also cause changes in the internal stress of the material, further affecting the overall quality of the product. In addition, excessively high temperatures may also damage the surface grinder itself, shorten its service life, and increase maintenance costs.
[0004] To address the above issues, it is necessary to design a surface grinder with a cooling function. Utility Model Content

The front of the second support plate 51 A connecting plate 22 is connected to the upper side, and a spray pipe 221 passes through the connecting plate 22. A guide block 23 is connected to the front side of the placement frame 3. The guide block 23 provides guidance for the electric slider 24. The electric slider 24 is installed on the guide block 23. A cleaning block 25 is connected to the upper side of the electric slider 24. The cleaning block 25 can directly contact the surface of the magnetic bed 4 to remove debris and dirt generated during processing. An infrared sensor 26 is installed on the right side of the placement frame 3. The infrared sensor 26 is used to detect the position or status of the workpiece to assist in automated operation. A cooling assembly is provided on the upper side of the first support plate 5. The cooling assembly includes a water tank 12, a cooler 13, a first water pump 14, a second water pump 15, and a spray pipe 16. The water tank 12 is symmetrically connected to the left and right sides of the upper side of the first support plate 5.Each of the two water tanks 12 has a cooler 13 installed on its opposite side. The cooler 13 cools the water in the water tanks 12. A first water pump 14 is installed on the upper rear side of each water tank 12, and a second water pump 15 is installed on the lower front side of each water tank 12. The second water pump 15 pumps the cooled water to a spray pipe 16. A spray pipe 16 is connected to the front of each of the two second water pumps 15. Both spray pipes 16 pass through the support frame 9 and spray the cooled water onto the grinding wheel 11 and the surface of the workpiece.
[0031] When this device is needed, the operator places the workpiece to be processed on the magnetic bed 4 and connects the two external pipes to the corresponding first water pump 14. Then, the pump 211 is started, drawing lubricating oil from the lubrication bottle 21 and dripping it onto the second electric slide rail 8 through the spray pipe 221, ensuring smooth operation of the second electric slide rail 8. When the lubricating oil reaches the appropriate amount, the pump 211 is turned off. Then, the first motor 6 is started, and the output shaft of the first motor 6 drives the screw 61 to rotate. The screw 61 drives the sliding plate 7, the second electric slide rail 8, the support frame 9, the second motor 10, and the grinding wheel 11 to move downwards. When the grinding wheel 11 moves to contact the surface of the workpiece, the first motor 6 is turned off, locking the position of the grinding wheel 11. Subsequently, the second motor 10 is started, and the output shaft of the second motor 10 drives the grinding wheel 11 to rotate. The grinding wheel 11 begins to grind the surface of the workpiece. During the grinding process, the second electric slide rail 8 is activated, causing the support frame 9, the second motor 10, and the grinding wheel 11 to move backward to achieve uniform grinding. At the same time, two first water pumps 14 and two coolers 13 are activated. The two first water pumps 14 draw water from the corresponding external pipes into the corresponding water tanks 12, and the two coolers 13 cool the water in the two water tanks 12. When the water temperature drops to a suitable temperature, the two second water pumps 15 are activated. The two second water pumps 15 draw the cooled water from the corresponding water tanks 12 into the corresponding water spray pipes 16, and spray it onto the grinding surface through the two water spray pipes 16. To prevent damage to the grinding wheel 11 or the workpiece due to high temperature, some of the cooled water will fall onto the workpiece during the cooling process, preventing deformation due to excessive temperature. After the workpiece surface is polished, the second motor 10, the second electric slide rail 8, the two first water pumps 14, the two coolers 13, and the two second water pumps 15 are turned off to stop the polishing operation. If the grinding wheel 11 is damaged due to prolonged use and needs to be replaced, the operator pulls the fixed plate 17 outward along the rotating plate 18. During this process, the fixed plate 17 will apply pressure to the two locking rods 19, causing them to move outward and compressing the two elastic elements 20 until the two locking rods 19 move completely away from the fixed plate. After step 17, the fixed plate 17 and the damaged grinding wheel 11 can be removed. Then, the two locking rods 19 are no longer under pressure. Under the reset action of the two elastic elements 20, the two locking rods 19 move inward until they reach their initial positions. Next, the operator installs the new fixed plate 17 and grinding wheel 11 onto the rotating disk 18 and pushes the new fixed plate 17 and grinding wheel 11 inward along the rotating disk 18. During the movement of the new fixed plate 17, it applies pressure to the two locking rods 19, causing them to move outward. The two elastic elements 20 are compressed until the new fixed plate 17 and grinding wheel 11 move to the appropriate positions. Afterward, the two locking rods 19 are no longer under pressure, and under the reset action of the two elastic elements 20...The two levers 19 move inward and securely lock the fixing plate 17. When cleaning of the magnetic bed 4 surface is required, the electric slider 24 is activated. The electric slider 24 drives the cleaning block 25 to move to the left along the guide block 23 until the cleaning block 25 is in full contact with the magnetic bed 4 surface. As the electric slider 24 moves, the cleaning block 25 continues to move along the magnetic bed 4 surface, effectively cleaning the entire surface area and ensuring that all debris is removed. Once the magnetic bed 4 surface is thoroughly cleaned, the electric slider 24 is deactivated.
