DETAILED DESCRIPTION

[0032] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] The present application embodiment discloses a CNC lathe end surface grinding tool, such as Figure 1 As shown, the base 1 includes one end of the base 1 extending into the groove of the belt pulley 5, and the end of the base 1 extending into the groove of the belt pulley 5 is provided with an oil stone 3, and the oil stone 3 is used to grind the end face 51. In actual operation, the operator moves the base 1, and the operator causes the base 1 to drive the oil stone 3 into the groove of the belt pulley 5, and then limits the belt pulley 5 through the CNC lathe, and causes the belt pulley 5 to rotate, and the oil stone 3 can grind the end face 51.

[0035] like Figure 2 , 3 As shown in FIG. 4 , a clamp 2 is provided on the base 1, and the oilstone 3 and the clamp 2 are detachably connected. The clamp 2 and the base 1 slide relative to each other. A sliding groove 11 is provided at one end of the base 1 facing the belt pulley 5, and the clamp 2 slides in the sliding groove 11. An elastic member is provided in the base 1, and the elastic member is a spring 12. One end of the spring 12 is fixedly connected to the bottom of the sliding groove 11, and the other end is fixedly connected to the clamp 2. Under natural circumstances, the spring 12 applies a thrust to the clamp 2, so that the clamp 2 moves away from the bottom of the sliding groove 11. The operator installs the oilstone 3 on the clamp 2, and then moves the base 1 so that one end of the base 1 extends into the groove of the belt pulley 5. The base 1 can drive the clamp 2 to extend into the groove of the belt pulley 5, so that the oilstone 3 is located in the groove of the belt pulley 5. The clamp 2 moves away from the bottom of the sliding groove 11 under the action of the spring 12, so that the oilstone 3 moves away from the bottom of the sliding groove 11, so that the oilstone 3 abuts against the end face 51, which is convenient for grinding the end face 51.

[0036] like Figure 2 , 3As shown in FIG. 5 , the oilstone 3 includes a connecting portion 31 and a grinding portion 32. An embedding hole 21 is provided in the fixture 2. One side of the connecting portion 31 is located in the embedding hole 21, and the other side extends out of the fixture 2. The grinding portion 32 is fixedly connected to the side of the connecting portion 31 extending out of the fixture 2. The side of the grinding portion 32 away from the connecting portion 31 grinds the end surface 51. The fixture 2 is provided with a threaded hole 22, the threaded hole 22 is for screwing in a bolt, and the threaded hole 22 is connected to the embedding hole 21; the base 1 is provided with an auxiliary hole 13, and the auxiliary hole 13 is connected to the threaded hole 22. After the operator passes the bolt through the auxiliary hole 13, it is screwed into the threaded hole 22. When the oilstone 3 and the fixture 2 need to be installed, the connecting part 31 is moved so that one side of the connecting part 31 is moved into the embedding hole 21, and then the bolt is screwed into the threaded hole 22, and the bolt is rotated until it abuts against the connecting part 31. The bolt can limit the connecting part 31 so that the connecting part 31 is fixed in the embedding hole 21, thereby achieving fixed installation of the oilstone 3 and the fixture 2, making it easier for the grinding part 32 to abut against the end face 51 and grind the end face 51.

[0037] like Figure 3 and 6 As shown, a baffle 4 is detachably connected to one end of the base 1 facing the belt pulley 5, the baffle 4 is coaxial with the base 1, the clamp 2 can slide to abut against the baffle 4, and a limiting hole 41 is provided on the baffle 4 for the connection part 31 to pass through. The baffle 4 can limit the sliding distance of the clamp 2, and the limiting hole 41 can limit the connection part 31, thereby further limiting the oilstone 3, improving the stability of the oilstone 3, and improving the stability of the oilstone 3 when grinding the end face 51, which is convenient for the grinding work of the end face 51.

[0038] like Figure 3 and 6 As shown, the baffle 4 is provided with a connecting bolt 42, which passes through the baffle 4 and is threadedly connected to the base 1. When the baffle 4 needs to be installed, the baffle 4 is moved to a suitable position on the base 1, and then the connecting bolt 42 is screwed in, so that the connecting bolt 42 passes through the baffle 4 and is threadedly connected to the base 1. The connecting bolt 42 can limit the baffle 4, so that the baffle 4 and the base 1 are fixed, thereby realizing the installation of the two.

[0039] The implementation principle of a CNC lathe end surface grinding tool in the embodiment of the present application is:

[0040] The operator places the clamp 2 into the sliding groove 11, and fixes one side of the spring 12 to the bottom of the sliding groove 11, and the other side to the clamp 2; then the baffle 4 is installed, moved to a suitable position, and fixedly installed to the base 1 by the connecting bolt 42; finally, the oilstone 3 is installed, the connecting part 31 is moved, one side of the connecting part 31 passes through the limiting hole 41, and is moved to the embedded hole 21, and after the bolt passes through the auxiliary hole 13, it is completely screwed into the threaded hole 22 until the bolt abuts against the connecting part 31. The bolt can limit the connecting part 31, thereby realizing the fixed installation of the oilstone 3.

[0041] During actual operation, the operator moves the base 1 toward the belt pulley 5 through the CNC lathe, so that one end of the base 1 is located in the groove of the belt pulley 5. At this time, the clamp 2 moves away from the base 1 under the action of the spring 12, so that the grinding part 32 abuts against the end face 51, and the belt pulley 5 is rotated by the CNC lathe, so that the oilstone 3 grinds the end face 51.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
