Description

Technical Field

[0001] The utility model relates to the technical field of numerical control equipment, in particular to a tool for a numerical control grinder. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, superfinishing machines, belt grinders, grinders and polishing machines. Grinding machines can process materials with higher hardness, such as hardened steel, cemented carbide, etc., and can also process brittle materials, such as glass and granite. Grinding machines can perform high-precision grinding with very small surface roughness, and can also perform high-efficiency grinding, such as high-power grinding.

[0003] In the existing patent application number 202010887501.1, a "tool for a CNC tool grinder" is disclosed, including a positioning box, a fixed block, and a cooling pipe. The bottom of the fixed block is welded to the top of the positioning box, and one end of the cooling pipe is embedded in the front side of the fixed block. However, in this application setting, the grinder tool and its base are fixedly installed. That is to say, if the subsequent grinder tool is scrapped or worn, this product can only be discarded together with its base. In addition, in this product, multiple mechanisms are installed on the base. Therefore, discarding it is too wasteful, which increases the production cost and has low practicality.

[0004] Therefore, it is necessary to design a tool for CNC grinding machine with strong practicality and stability. Utility Model Content

By setting the threaded column 7, the effect of quickly installing or removing the grinding machine tool 9 can be achieved. In this way, when the grinding machine tool 9 is scrapped or worn, it does not need to be discarded together with the base 1. It only needs to squeeze out the grinding machine tool 9 threadedly connected with the threaded column 7, which saves resources, effectively reduces the production cost, and is more practical. At the same time, when the threaded column 7 is not connected to the grinding machine tool 9, the operator The operator can store it in the base 1. The base 1 is clamped and fixed by the machine tool chuck on the machine tool, and the extended connecting shaft 8 is connected to an output end of the machine tool. The operator drives the connecting shaft 8 to rotate by controlling the machine tool. The connecting shaft 8 drives the support 2 fixed at one end, and the support 2 drives the crown gear part 3 fixed at one end to rotate together. The crown gear part 3 drives the two sets of bevel gear parts 4 meshed and connected on one side to rotate. One end of the central axis of the bevel gear part 4 is located on the inner side of the base 1, and the base 1 is used to support the bevel gear part 4. When the bevel gear part 4 rotates, it drives the turntable 5 fixed at one end.

After the grinder tool 9 is installed, when the grinder tool 9 is working, it is inevitable that the grinder tool 9 itself will vibrate or even shake due to the grinding tool. The operator only needs to extend the telescopic rod 11 and extend it into the straight groove opened on the base 1. When the spring member 16 is squeezed by the marble 17, it will be compressed and successfully bring the marble 17 into the straight groove. When the telescopic rod 11 is extended to the bottom of the straight groove, the marble 17 is meshed with the second card path 18 under the rebound reset of the spring member 16. In addition, the stabilizing assembly is provided with two groups, located on both sides of the grinder tool 9, which can effectively ensure the stability of the grinder tool 9 and prevent it from shaking.
