[0002] A surface grinder is a device that improves the flatness of a workpiece by grinding it. It is widely used in the process of mechanical processing. In mechanical processing, a ring is a basic and simple geometric form of the workpiece. The ring can be designed as a function or as a display. Different design ideas can make the workpiece form of the ring have different effects. Designers can use the ring as a carrier to present different effects by combining materials and functions.

[0003] After searching the prior art, it is found that when surface grinding is performed on an annular workpiece, the grinding process is often completed by translational movement of the workpiece or the grinding tool. However, during the translational grinding process, the contact area between the grinding tool and the annular workpiece changes all the time, and the grinding force of the grinding tool grinding the annular workpiece changes. Due to the different grinding forces, grinding errors occur in the parts after grinding. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1 — Figure 5 As shown, a surface grinder for grinding processing includes a bed 1, on which a fixing mechanism 2 and a moving mechanism 3 are installed, a grinding mechanism 4 is arranged at the bottom of the moving mechanism 3, the bed 1 includes a workbench 101, a mounting frame 102 is welded on the top of the workbench 101, a workpiece table 103 is welded at the middle position of the top of the workbench 101, and an annular workpiece 104 is arranged on the top of the workpiece table 103.

[0025] In this embodiment, the fixing mechanism 2 includes two symmetrically arranged fixing blocks 201, which are arranged on both sides of the workpiece table 103. A slide groove 202 is opened in the fixing block 201. A rocker 203 is rotatably connected in one fixing block 201. A bidirectional screw rod 204 is welded to one end of the rocker rod 203. The bidirectional screw rod 204 passes through the fixing block 201 and is rotatably connected to the fixing block 201. A moving block 205 is threadedly connected to the bidirectional screw rod 204. A symmetrically arranged clamping block 206 is connected to one side of the top of the moving block 205 by bolts. The annular workpiece 104 cooperates with the clamping block 206. The clamping block 206 is wedge-shaped. The two symmetrically arranged annular workpieces 104 with different curvatures and radii can be clamped, and have a wide range of applications.

[0026] In this embodiment, the motion mechanism 3 includes a hydraulic cylinder 301, the output end of the hydraulic cylinder 301 is connected to a connecting disk 302, the bottom of the connecting disk 302 is rotatably connected to a worm gear 303, the bottom of the worm gear 303 is fixedly connected to a rotating disk 304, the midpoint of the bidirectional lead screw 204 and the center of the rotating disk 304 are located on the same vertical line, the bottom edge of the connecting disk 302 is connected to a first motor 305 by bolts, the output shaft of the first motor 305 is connected to a worm 306 meshing with the worm gear 303, and a slot 307 is eccentrically provided at the bottom of the rotating disk 304. When the grinding mechanism 4 processes the workpiece, the first motor 305 drives the worm 306 to rotate, and the worm 306 can drive the worm gear 303 and the rotating disk 304 to rotate at the bottom of the connecting disk 302 through the meshing relationship with the worm gear 303, thereby ensuring that the grinding contact area of ​​the grinding mechanism 4 when grinding the annular workpiece 104 is fixed, avoiding processing errors caused by changes in the grinding area, and improving the grinding quality.

[0027] In this embodiment, the grinding mechanism 4 includes a second motor 401, which is bolted to the slot 307 at the bottom of the rotating disk 304. The output end of the second motor 401 is connected to a grinding disk 402. The bolt connection facilitates the removal of the second motor 401 and the grinding disk 402, and the grinding disk 402 can be replaced when the annular workpiece 104 of different materials is used.

[0028] Working principle: When the device is in use, the staff puts the annular workpiece 104 on the top of the workpiece table 103 and rotates the rocker 203. The rocker 203 drives the bidirectional screw 204 to rotate. The bidirectional screw 204 drives the two moving blocks 205 to approach each other in the slide groove 202 at the same time. The moving block 205 pushes the clamping block 206 to fix the annular workpiece 104 at the midpoint of the distance of the clamping block 206 for easy positioning. Then, according to the material of the annular workpiece 104, a suitable grinding disc 402 is selected. The diameter of the grinding disc 402 should be larger than the inner and outer radius difference of the annular workpiece 104. The installed second motor 401 is connected to the slot 307 by bolts. When surface grinding is performed, The hydraulic cylinder 301 drives the connecting disk 302 to descend, and starts the first motor 305 and the second motor 401 at the same time. The first motor 305 drives the worm 306 to rotate. The worm 306 can drive the worm wheel 303 and the rotating disk 304 to rotate slowly at the bottom of the connecting disk 302 through the meshing relationship with the worm wheel 303. When the rotating disk 304 drives the grinding disk 402 to descend to the upper surface of the annular workpiece 104, the surface grinding of the annular workpiece 104 begins. As the rotating disk 304 rotates, the eccentrically arranged second motor 401 also moves synchronously. In this process, the grinding contact area between the grinding disk 402 and the annular workpiece 104 is always fixed, thereby improving the grinding effect.
