Description

Technical Field

[0001] The present invention relates to the technical field of grinding machine equipment, and particularly to a high-precision grinding machine tailstock and its control system. Background Art

[0002] The tailstock of an external cylindrical grinding machine, as a part of the grinding machine, is designed to centrally support the free end of a long workpiece during equipment operation. The tailstock is located opposite the headstock on the upper right side of the grinding machine. By sliding along the sliding system to engage the part being processed, the tailstock can accommodate components of different lengths.

[0003] However, during the use of an external cylindrical grinding machine, it is necessary to align the axis of the tailstock to prevent the axis of the tailstock and the workpiece from not being on the same horizontal line, which may cause stress bending when the workpiece is fixed on the tailstock, resulting in severe collisions between the cutting tool and the workpiece during the machining process, leading to tool breakage and workpiece breakage. In the prior art, the grinding machine cannot collect alignment data for the axis of the tailstock, nor can it achieve high-precision intelligent automatic adjustment of the tailstock. The prior art still uses manual adjustment, resulting in low adjustment accuracy and poor safety.

[0004] 1. Patent document CN110411719B discloses a device and evaluation method for measuring the dynamic stiffness of a grinding machine tailstock. The above patent realizes the inspection of whether the dynamic stiffness of the center point, sleeve and housing of the grinding machine tailstock meets the requirements and whether the overall dynamic stiffness of the tailstock meets the requirements. However, the above patent cannot realize the function of collecting the offset amount between the axis of the tailstock and the workpiece.

[0005] 2. Patent document CN116408726B discloses a high-precision headstock and tailstock center point structure for a roll grinding machine and a roll grinding machine. The above patent realizes the balance of radial and axial forces from the roll and obtains a high-precision roll grinding effect. However, the above patent cannot realize the function of adjusting the axis of the grinding machine tailstock.

[0006] 3. Patent document CN108214126B discloses a rubber manufacturing external cylindrical grinding machine. The above patent realizes that during the rubber external grinding process, the guard plate automatically opens and waste is centrally collected and processed to prevent waste from splashing and falling inside the device or injuring personnel. However, the above patent cannot realize the function of remotely intelligent adjustment control for the adjustment of the grinding machine tailstock.

[0007] 4. Patent document CN107571122B discloses a camshaft cross slide grinding machine. The above patent realizes the convenient and rapid adjustment of the position of the camshaft and the grinding wheel, and the grinding efficiency of the camshaft is higher. However, the above patent cannot realize the functions of fault detection and emergency shutdown safety protection control for the grinding machine tailstock.

[0008] In summary, the above-mentioned patent cannot implement the functions of collecting the offset between the tailstock and the workpiece axis, adjusting the axis of the grinding machine tailstock, remotely and intelligently controlling the adjustment of the grinding machine tailstock, and detecting faults and emergency shutdown safety protection control of the grinding machine tailstock, resulting in problems such as collision and fracture between the workpiece and the tool, stress fracture of the workpiece, low accuracy of manual adjustment, low production safety, poor production efficiency, and poor workpiece processing effect;
