Problems solved by technology
Although the three-jaw chuck can be used to fix the cylindrical workpiece, since only three jaws of the three-jaw chuck are in contact with the cylindrical workpiece, the cylindrical workpiece is only subjected to force at three points, and the force is very uneven. , and even cause deformation of the cylindrical workpiece
Therefore, it is difficult to ensure the quality of the processed workpiece by using the three-jaw chuck to fix the cylindrical workpiece, which makes the quality of the processed workpiece poor

Embodiment Construction
[0012] Such as figure 1 with figure 2 As shown, the cylindrical workpiece processing fixture of the present invention includes a base 2 and a conical top column 3 . The base 2 is cylindrical, and its lower end is processed with a bottom. The conical top column 3 is conical with a large top and a small bottom. Four arc-shaped blocks 5 are evenly distributed around the base 2, and the four arc-shaped blocks 5 are spliced to form a circular ring with a rectangular cross section. One side of the inner circle of the arc-shaped block 5 is all processed with a radial expansion head 4, and the corresponding positions of the base 2 corresponding to the radial expansion head 4 are all processed with radial slide holes. 4 is sliding shape and stretches in the radial slide hole, and the 4 inner ends of the radial telescoping head are all conical surfaces with a large top and a small bottom. An extension spring 6 is arranged between the middle of the lower side of the arc-shaped blo...

The invention relates to a fixture for machining cylindrical workpieces. The fixture is characterized by comprising a cylindrical base and a big-end-up conical ejector post, a cylindrical bottom is arranged at the lower end of the base, arc-shaped blocks are uniformly distributed on the periphery of the base and are spliced into a circular ring with a rectangular cross section, a radial telescopic head is arranged on one side of an inner circle of each arc-shaped block, a radial sliding hole is formed in the position of the base corresponding to the corresponding radial telescopic head, the radial telescopic heads slidably extend into the radial sliding holes, the inner ends of the radial telescopic heads are provided with big-end-up conical surfaces, a tension spring is arranged between the middle of the lower side face of each arc-shaped block and the adjacent middle of the cylindrical bottom of the base, and the conical surfaces of the inner ends of the radial telescopic heads form a big-end-up conical hole matched with the conical ejector post when all tension springs are not stretched. By the aid of the fixture, the quality of the machined workpieces can be ensured, the machining quality of the workpieces is improved, and the fixture is applicable to fixing when the cylindrical workpieces are machined.
Description
technical field [0001] The invention relates to a clamp. Specifically, it is a fixture used to fix cylindrical workpieces when processing cylindrical workpieces. Background technique [0002] At present, in the field of mechanical processing, when processing cylindrical workpieces, a three-jaw chuck is mostly used to fix the cylindrical workpiece. Although the three-jaw chuck can be used to fix the cylindrical workpiece, since only three jaws of the three-jaw chuck are in contact with the cylindrical workpiece, the cylindrical workpiece is only subjected to force at three points, and the force is very uneven. , and even cause deformation of the cylindrical workpiece. Therefore, it is difficult to ensure the quality of the processed workpiece by using the three-jaw chuck to fix the cylindrical workpiece, so that the quality of the processed workpiece is poor. Contents of the invention [0003] The problem to be solved by the present invention is to provide a jig for proc...
