Problems solved by technology
[0002] When the machine tool is processing parts, the shaft parts are clamped by the three-jaw self-centering chuck, and the long shaft workpiece needs to use the tip for tail support, but the tip can only be used to position the tail end face of the workpiece. For long shaft thin workpieces , because the outer end surface is supported by the tip, it is impossible to use the end turning tool for turning, but the support cannot be realized by removing the tip, especially for slender shaft workpieces. If there is no support, the workpiece will be squeezed by the tool during end turning, resulting in tool deformation

The invention discloses a tailstock support device of a numerical control lathe. The device comprises a tailstock mounted on a lathe guide rail; the tailstock is mounted on the guide rail through a tailstock slide block at the bottom; fixing sleeves I are arranged on the two sides of the tailstock; support shaft rods, whose two ends extend out, are mounted in the fixing sleeves I; the outer side ends of the support shaft rods are perpendicularly provided with fixing sleeves II; the upper end surfaces of the fixing sleeves II are open; springs are arranged in the open ends of the fixing sleevesII; floating rods are inserted in the open ends of the fixing sleeves II; the bottoms of the floating rods make contact with the upper end surfaces of the springs; brackets are mounted on the inner side surfaces of the two floating rods; a support cavity is defined by the brackets; a rolling mechanism is arranged on the bottom surface of the support cavity; and workpieces are in rolling contact with the upper end surface of the rolling mechanism. The device is simple in structure, can be used for supporting slender shaft parts, is used for auxiliary support in end surface machining, and addsthe support mode of the tailstock to achieve the use flexibility.
Description
technical field [0001] The invention relates to the field of industrial machine tool processing, in particular to a tailstock support device of a numerically controlled lathe. Background technique [0002] When the machine tool is processing parts, the shaft parts are clamped by the three-jaw self-centering chuck. The long shaft workpiece needs to use the tip for tail support, but the tip can only be used to position the tail end face of the workpiece. For long shaft thin workpieces , because the outer end surface is supported by the tip, it is impossible to use the end turning tool for turning, but the support cannot be achieved by removing the tip, especially for slender shaft workpieces. If there is no support, the workpiece will be squeezed by the tool during end turning, resulting in Tool deformation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tailstock support device that can be used to support slen...
