[0026] As Figures 1-4 shown, the present utility model has the following specific embodiments.

[0027] Embodiment:

[0028] A precision workpiece grinding machine with a positioning structure includes a processing table 1. Two slide bars 13 are fixedly connected to the top of the processing table 1. One end of the two slide bars 13 is movably connected to a moving seat 3. A first column 32 is fixedly connected to the top of the moving seat 3. A lower clamping plate 321 is fixedly connected to one end of the first column 32. A support plate 4 is fixedly connected to the top of the moving seat 3. Two second limit ports 41 are opened at the rear side of the support plate 4. A moving plate 44 is movably connected inside the second limit port 41. A side plate 441 is fixedly connected to one end of the moving plate 44. A hydraulic cylinder 42 is connected through the top of the support plate 4. The telescopic end of the hydraulic cylinder 42 is fixedly connected to an upper clamping plate 421. A second column 43 is fixedly connected inside the support plate 4. A limit plate 431 is fixedly connected to one end of the second column 43. It further includes:

[0029] A power mechanism for driving the displacement of the side plate 441;

[0030] A grinding mechanism for grinding the workpiece.

[0031] By adopting the above technical solution, when using the device, first place the workpiece to be polished on the lower clamping plate 321. The limiting plate 431 connected to the second column 43 limits the workpiece. Then, the side plate 441 is driven to displace by the power mechanism, so that the side plate 441 positions the workpiece in the center. Next, the hydraulic cylinder 42 is opened to push the upper clamping plate 421 to move. The upper clamping plate 421 cooperates with the lower clamping plate 321 to clamp the workpiece. Then, the moving seat 3 is driven to move on the processing table 1, so that the moving seat 3 drives the workpiece to approach the grinding mechanism. Finally, the grinding mechanism is opened to grind the workpiece. The structure is reasonable, which is convenient for centering and positioning the grinding of the workpiece, avoiding the inclination of the grinding surface and improving the grinding quality.

[0032] Specifically, the power mechanism includes a transmission box 5. The transmission box 5 is fixedly connected to the rear side of the support plate 4. A bidirectional lead screw 53 penetrates through the outer surface of the transmission box 5. A worm gear 54 is fixedly connected to the bidirectional lead screw 53. A third servo motor 51 is fixedly connected to the top of the transmission box 5. The output shaft of the third servo motor 51 is fixedly connected to a worm 52, and the worm gear 54 is meshed with the worm 52.

[0033] Two moving plates 44 are respectively movably connected to both ends of the bidirectional lead screw 53, and the thread directions at both ends of the bidirectional lead screw 53 are opposite.

[0034] By adopting the above technical solution, the workpiece to be clamped can be centered and positioned. That is, by turning on the third servo motor 51, the worm 52 can be driven to rotate. The worm 52 can drive the meshed worm gear 54 to rotate. Since the two moving plates 44 are respectively threadedly connected to both ends of the bidirectional lead screw 53, and since the thread directions at both ends of the bidirectional lead screw 53 are opposite, the two moving plates 44 can be driven to move through the second limiting port 41 for limiting, and the moving plate 44 can drive the connected side plate 441 to move, and then the two side plates 441 position the workpiece in the center.

[0035] Specifically, the grinding mechanism includes a linear motor 11 and a second servo motor 2. The linear motor 11 is fixedly connected to the processing table 1. The second servo motor 2 is fixedly connected to the movable seat of the linear motor 11. The output shaft of the second servo motor 2 is fixedly connected to a grinding wheel 21.

[0036] By adopting the above technical solution, the workpiece can be ground. That is, the set second servo motor 2 can drive the grinding wheel 21 to rotate, and the grinding wheel 21 can grind the workpiece. At the same time, the linear motor 11 can drive the second servo motor 2 to displace, so that the grinding wheel 21 can perform linear displacement and grinding.

[0037] Specifically, the upper clamping plate 421 is located directly above the lower clamping plate 321, and the two side plates 441 are located on both sides of the lower clamping plate 321.

[0038] By adopting the above technical solution, the upper clamping plate 421 and the lower clamping plate 321 can clamp the workpiece to be processed, and the provided side plate 441 can center and position the workpiece to be clamped.

[0039] Specifically, a first limiting port 12 is formed at the bottom of the processing table 1, a lifting lug 31 is fixedly connected to the bottom of the moving seat 3, a first servo motor 14 is fixedly connected to the bottom of the processing table 1, an output shaft of the first servo motor 14 is fixedly connected to a screw rod 15, and the screw rod 15 is in threaded cooperation with the lifting lug 31.

[0040] By adopting the above technical solution, the moving seat 3 can be driven to move on the processing table 1, that is, the provided first servo motor 14 can drive the screw rod 15 to rotate. Since the screw rod 15 is in threaded cooperation with the lifting lug 31 and the lifting lug 31 is fixed to the bottom of the moving seat 3, the moving seat 3 can be driven to move on the sliding rod 13, and the moving seat 3 can drive the clamped workpiece to approach the grinding mechanism for grinding processing.
