[0025] By adopting the above technical solutions, the vacuum workpiece adsorber 310 fixes the workpiece by negative pressure, eliminating the need for mechanical clamping. The loading and unloading process only requires controlling the vacuum switch, which greatly improves the loading and unloading efficiency. The sliding fit between the guide rod 39 and the guide hole 37, as well as the transmission stability of the driving bevel gear 32 and the driven bevel gear 33, improve the alignment accuracy between the workpiece and the grinding disc 24. The drive cylinder 36 can precisely control the grinding pressure and reduce surface errors.

[0026] In this embodiment, the rotary motor 31 is fixedly installed inside the dual-station main unit base 11, and a mounting bracket 12 is provided on the rear side of the dual-station main unit base 11. The inner side of the mounting bracket 12 is rotatably connected to the column 34. The dual-station main unit base 11 is provided with rotary bearings 13 at both the upper and lower rear ends. The rotary bearing 13 at the lower rear end is rotatably connected to the lower end of the column 34, and the rotary bearing 13 at the upper rear end is rotatably connected to the upper end of the column 34. The mounting bracket 12 is located between the two rotary bearings 13. The dual-station main unit base 11 has symmetrically installed annular protective rings 14 on the upper front side. Each annular protective ring 14 has a base plate 15 at its bottom, and a drain pipe 16 is provided on one side of the annular protective ring 14.

[0027] By adopting the above technical solution, the annular protective ring 14 prevents the grinding fluid from splashing, and the drain pipe 16 and the drain port 17 form a closed-loop recycling system, which improves the waste liquid recovery rate and reduces media waste and environmental pollution. The column 34 is double-fixed by the upper and lower rotating bearings 13, which, together with the support of the mounting bracket 12, extends the service life of the equipment.

[0028] In this embodiment, the dual-station main unit 11 is symmetrically provided with drain ports 17 on the left and right sides, and the drain ports 17 are correspondingly provided with drain pipes 16. The upper surface of the dual-station main unit 11 is symmetrically provided with grinding fluid nozzles 18. The upper end of the dual-station main unit 11 is symmetrically fixedly installed with mounting frames 19. The ends of the mounting frames 19 are all connected to workpiece placement trays 110. The workpiece placement trays 110 are provided with multiple placement holes in a ring array. The symmetrically arranged workpiece placement trays 110 are all located inside the symmetrically arranged annular protective rings 14; the two upper surfaces of the mounting frame 19 are fixedly mounted with drive motors 21, and the lower end of the drive motors 21 passes through the mounting frame 19 and is connected to the transmission mechanism 22. The other end of the transmission mechanism 22 is connected to the lower shaft of the grinding disc 24. The grinding disc 24 is rotatably connected to the mounting bracket 23. The mounting bracket 23 is connected to the inner side of the dual-station main unit base 11. The grinding disc 24 passes through the slot in the middle of the chassis 15 and is located inside the annular protective ring 14. The grinding disc 24 is located at the lower end of the workpiece placement tray 110.

[0029] By adopting the above technical solution, the four vacuum workpiece adsorbers 310 arranged in a ring on the connecting seat 38 can adsorb multiple workpieces at the same time; the ring array of placement holes on the workpiece placement tray 110 provides pre-positioning for the workpieces, improving operating efficiency.

[0030] The working principle of this utility model is as follows: The equipment takes the dual-station grinding base 1 as the core support structure and achieves dual-station synchronous grinding through the symmetrically arranged grinding disc assembly 2. During operation, the workpiece to be ground is first placed in the placement hole of the workpiece placement disc 110, and the vacuum workpiece adsorber 310 firmly adsorbs the workpiece through negative pressure.

[0031] The rotary motor 31 in the grinding machine assembly 3 drives the column 34 and connecting arm 35 to rotate through the meshing of the active bevel gear 32 and the driven bevel gear 33, thereby moving the workpiece above the grinding disc 24; the drive cylinder 36 pushes the connecting seat 38 to move down, and the guide rod 39 slides along the guide hole 37 to ensure displacement accuracy, so that the workpiece contacts the grinding disc 24. Meanwhile, the drive motor 21 of the grinding disc assembly 2 drives the grinding disc 24 to rotate through the transmission mechanism 22, and the grinding operation is completed by the grinding liquid sprayed out by the grinding liquid nozzle 18. After the grinding is completed, the vacuum suction device releases the workpiece, and the dual-station alternating operation realizes continuous production. The vacuum workpiece adsorber 310 fixes the workpiece by negative pressure, eliminating the need for mechanical clamping. The loading and unloading process only requires controlling the vacuum switch, greatly improving loading and unloading efficiency. The sliding fit between the guide rod 39 and the guide hole 37, as well as the transmission stability of the driving bevel gear 32 and the driven bevel gear 33, improve the alignment accuracy between the workpiece and the grinding disc 24. The drive cylinder 36 can precisely control the grinding pressure, reducing surface errors. The annular protective ring 14 prevents the grinding fluid from splashing, and the drain pipe 16 and the drain port 17 form a closed-loop recovery system, which improves the waste liquid recovery rate and reduces media waste and environmental pollution. The column 34 is double-fixed by the upper and lower rotating bearings 13, which, together with the support of the mounting bracket 12, extends the service life of the equipment. The four vacuum workpiece adsorbers 310 arranged in a ring on the connecting seat 38 can adsorb multiple workpieces at the same time; the ring array of placement holes on the workpiece placement tray 110 provides pre-positioning for the workpieces, improving operating efficiency.
