During the adjustment, the same water level is provided at the two sides of the guide rail of the moving head-tailstock, so that the precision and stability of the head-tailstock are not high, and the grinding precision is reduced due to the lateral force when large workpieces are machined, which affects the overall use. In addition, the length of the workpiece is different, and the process of adjusting the head-tailstock is very laborious, which greatly increases the cost of labor. SUMMARY

[0004] The utility model discloses a high-precision and high-stability grinder head-tailstock structure to solve the above problems in the prior art.

[0006] In the high-low step static pressure guide rail grinder head-tailstock structure, the two guide rails are double linear guide rails, double V-shaped cross guide rails, double cross roller linear guide rails, linear guide rails and V-shaped cross guide rails, linear guide rails and cross roller linear guide rails, or V-shaped cross guide rails and cross roller linear guide rails.

[0007] In the high-low step static pressure guide rail grinder head-tailstock structure, the drive device one and the drive device two are servo motors, hydraulic cylinders or air cylinders.

[0008] In the high-low step static pressure guide rail grinder head-tailstock structure, the drive device one and the drive device two drive the headstock and the tailstock to move through a ball screw or a gear and rack assembly.

[0009] In the high-low order static pressure guide rail grinding machine head tail frame structure, the head frame comprises a motor part for controlling rotation of the top pin.

[0010] Compared with the prior art, the high-low order static pressure guide rail grinding machine head tail frame structure directly moves the tail seat in a system control manner, reduces manual moving time, increases work efficiency, improves workpiece machining precision, improves guide rail precision and stability, ensures machining quality, prevents workpiece lateral force, and improves workpiece clamping stability and machining stability.
