The invention discloses a workpiece clamping device and a roller scraper. The workpiece clamping device comprises a base, a lead screw, a first nut, a second nut, a first clamping seat and a second clamping seat, wherein two ends of the lead screw are arranged on the base; a first lead screw thread and a second lead screw thread with opposite rotating directions are arranged between two ends of the lead screw; the first nut is arranged on the first lead screw thread; the second nut is arranged on the second lead screw thread; the first clamping seat can be movably arranged on the base along the length direction of the lead screw and is fixed with the first nut; and the second clamping seat is opposite to the first clamping seat, can be movably arranged on the base along the length direction of the lead screw and is fixed with the second nut. According to the workpiece clamping device, the lead screw is driven to rotate, so that the two clamping seats can be close to each other on the base, clamping support is provided for workpieces with different diameters, the workpiece clamping device is simple in the overall structure and convenient to operate, long workpieces are prevented from expanding and deforming during the machining process, the requirement of the machining accuracy is met, and the machining efficiency is also improved.
Description
technical field [0001] The invention relates to the technical field of machine tools, in particular to a workpiece clamping device and a scraper. Background technique [0002] With the rapid development of my country's industry, the requirements for the processing performance, stability and machining accuracy of the machine tool machine tool in the machine tool industry are getting higher and higher. The scraping and rolling machine tool is a high-efficiency deep hole processing equipment that uses combined tools to perform rough boring, scraping and rolling processing on the inner holes of long workpieces such as cylinders and cylinders. [0003] Since the wall thickness of the long workpiece is thin and the length is not equal, in the process of machining the inner hole, if the length of the workpiece is longer, the workpiece will be bent and deformed due to its own weight, which will affect the machining accuracy of the workpiece. [0004] Therefore, it is a technical pr...
