Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a novel tailstock of a machine tool. Background Art

[0002] The tailstock of a machine tool is a part of a machine tool, which is used to clamp and support the workpiece. It is usually located at the tail of the machine tool bed and plays the role of supporting and fixing the workpiece. The main function of the tailstock is to provide support and clamping for the workpiece during the processing to ensure that the workpiece remains stable and meets the processing accuracy and quality requirements. The common machine tool tailstock is composed of a base, an adjustment mechanism and a push rod. This machine tool tailstock adjusts the position of the push rod through the adjustment mechanism so that the push rod can push the workpiece tightly to provide support. With the development of industry, pneumatic tailstocks and hydraulic tailstocks are used. This type of tailstock mainly drives the entire tailstock to move by pneumatic or hydraulic means, so that the push rod fixed on the tailstock can push and support the workpiece tightly. However, the ends of the push rods on the existing machine tool tailstocks are all conical. This design can be applied to most standard-shaped workpieces. Whether it is a cylindrical, conical or prismatic workpiece, the conical push rod can provide a good clamping effect. However, for some non-standard-shaped workpieces, the workpiece shape cannot be fully contacted with the conical push rod, resulting in unstable clamping or insufficient clamping force, which affects the processing of non-standard-shaped workpieces.
