Description

Technical Field

[0001] The utility model relates to the technical field of machine tool auxiliary support, in particular to an auxiliary support device for a precision machine tool. Background Art

[0002] When machining slender or poorly rigid workpieces with machine tools, the large cutting force of the tool often causes the workpiece to deform or even break, which not only affects the machining quality but also poses a safety hazard. Therefore, in order to prevent the above problems, an auxiliary support is often installed at the far end of the workpiece to increase the force-bearing capacity of the workpiece.

[0003] According to patent CN 203956551 U, an auxiliary support device for a large heavy machine tool is composed of an oil cylinder, a support sleeve, a roller bracket, a bracket, a base, shaft I, a bearing, a roller and shaft II. A bracket is arranged on the base, and an oil cylinder is installed at the other end of the base. A support sleeve is installed on the oil cylinder, and a roller bracket is installed between the support sleeve and the bracket, and a roller is arranged on the roller bracket. One end of the roller bracket is installed on the bracket through shaft II. Under the action of the oil cylinder, shaft II serves as a rotating shaft for the roller bracket to rotate. The bearing is installed and fixed inside the roller through shaft I, and the assembly consisting of shaft I, bearing and roller is installed on the roller bracket through shaft I.

[0004] This patent uses this device to solve the problem of small processing range of machine tools, and expands the performance of machine tools while ensuring processing accuracy. However, this patent can only provide auxiliary support for workpieces of the same diameter and cannot be applied to workpieces of different diameters, so its scope of application is relatively small.
