Technical Field
[0001] This utility model relates to a CNB grinding wheel of the oil nozzle batch grinding head type, belonging to the field of grinding wheel technology. Background Technology
[0002] Grinding wheels, also known as bonded abrasives, are abrasives in which ordinary abrasive grains are bonded together with a bonding agent to form a specific shape (mostly circular with a central through-hole) and possess a certain strength. They generally consist of abrasive grains, a bonding agent, and pores; these three parts are often referred to as the three essential elements of bonded abrasives. According to different bonding agents, common types include ceramic (bonded) grinding wheels, resin (bonded) grinding wheels, and rubber (bonded) grinding wheels. Grinding wheels are the most widely used and extensive type of abrasive. They rotate at high speeds and can perform rough grinding, semi-finishing, and finish grinding, as well as grooving and cutting, on the outer and inner diameters, planes, and various profiles of metal or non-metal workpieces. There are many types of grinding wheels, including those made of CNB material.
[0003] Chinese Patent Publication No. (CN 206967321 U) discloses a grinding wheel, belonging to the field of grinding tools, to solve the problem of difficulty in correcting wear on the grinding surface of current grinding wheels. It includes a circular grinding wheel body, comprising a base and several grinding rings. An inner core is embedded in the center of the base, and a mounting hole is formed at the center of the inner core. The grinding rings are sequentially fitted onto the base. This technical solution has a simple and reasonable structure and facilitates the correction of the grinding surface.
[0004] After prolonged use, the grinding part of the grinding wheel may be damaged, which will affect the normal grinding work. Since the grinding wheel is usually formed in one piece, the grinding wheel can only be replaced as a whole. This results in material waste of the un-grinded parts, making the replacement of the grinding wheel costly and inconvenient for operators.
[0005] To address this, a CNB grinding wheel with a batch grinding head and oil nozzle type is proposed. Utility Model Content

A grinding part 3 is provided at the bottom of the grinding disc 1. A protrusion 4 is fixedly installed on the top of the grinding part 3. Insertion holes 5 are opened on the surface of the protrusion 4. An installation component 2 is provided in the inner cavity of the grinding disc 1. The installation component 2 includes a turntable 201. The turntable 201 is located in the inner cavity of the grinding disc 1. A pull rod 202 is fixedly installed on the top of the turntable 201. Connecting rods 203 are movably connected to the four sides of the top of the turntable 201. Moving blocks 204 are movably connected to the bottom of the other end of the three connecting rods 203. Insertion blocks 205 are fixedly installed on the inner side of the three moving blocks 204.
[0030] By setting the mounting component 2, the movement of the pull rod 202 allows the connecting rod 203 to move the moving block 204 and the insert block 205. By adjusting the position of the insert block 205, the grinding part 3 can be fixed or disassembled, making it convenient to replace the grinding part 3 separately when it is damaged after long-term use. Compared with traditional grinding wheels, the area of the grinding disc 1 can be preserved. Compared with integrated grinding wheels, the cost of replacing the grinding part 3 can be reduced, making it more convenient for operators to use.
[0031] Example 2
[0032] like Figure 1 , Figure 3 , Figure 5 and Figure 6As shown, in one embodiment, slots 206 are provided around the inner cavity of the grinding disc 1. Three inserts 205 pass through the inner cavities of the three slots 206 and are inserted into the inner cavities of the three insertion holes 5. The inner cavities of the three slots 206 and the inner cavities of the three insertion holes 5 are all in the same horizontal direction and are interconnected. Movable grooves 207 are provided around the bottom of the inner cavity of the grinding disc 1. The bottoms of the three movable blocks 204 are slidably connected to the inner cavities of the three movable grooves 207. An annular groove 208 is provided in the inner cavity of the grinding disc 1. The outer side of the turntable 201 is slidably connected to the inner cavity of the annular groove 208. A sliding groove 209 is provided on the top of the grinding disc 1. A pull rod 202 passes through the inner cavity of the sliding groove 209 and extends to the top of the grinding disc 1. The top of the pull rod 202 is threaded with a fixing bolt 210. The bottoms of the two fixing bolts 210 are threaded to the inner surface of the grinding disc 1.
[0033] By setting the slot 206, the movement of the insert block 205 can be limited to prevent it from shifting during movement, thus affecting the fixing of the grinding part 3. By setting the moving groove 207, the movement of the moving block 204 can be limited to prevent it from shifting during movement, thus affecting the disassembly and assembly of the grinding part 3. By setting the annular groove 208, the movement of the turntable 201 can be limited to ensure the stability of the turntable 201 during rotation. By setting the sliding groove 209, the movement of the pull rod 202 can be limited to ensure the stability of the fixing of the grinding part 3. By setting the fixing bolt 210, the position of the pull rod 202 can be fixed to prevent the pull rod 202 from shifting, thus affecting the installation of the grinding part 3.
[0034] In operation, when the grinding part 3 needs replacement after prolonged use, the limiting position on the pull rod 202 is released by loosening the fixing bolt 210. Then, by pulling the fixing bolt 210, the turntable 201 rotates. Through its interaction with the connecting rod 203, the turntable 201 causes the connecting rod 203 to pull the moving block 204 outwards. The moving block 204 then moves the insert block 205 out of the inner cavity of the insertion hole 5. Finally, the grinding part 3 is pulled upwards to complete the grinding process. Disassembly of the paired grinding parts 3: When it is necessary to install the grinding parts 3, the grinding parts 3 are snapped into the inner side of the grinding disc 1, and then the pull rod 202 is pulled in the opposite direction. At this time, the pull rod 202 drives the turntable 201 to rotate in the opposite direction. The turntable 201 and the connecting rod 203 cooperate with each other. The connecting rod 203 drives the moving block 204 and the insert block 205 to move inward. The insert block 205 is then inserted into the inner cavity of the insertion hole 5, thus completing the fixing of the grinding parts 3 and realizing the replacement of the grinding parts 3.
[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
