Cnc tool holder pull stud

The working principle of tool holder cnc pull stud: one end of the cnc pull stud is connected with the machine tool chuck, the other end is connected with the tool holder, the d part is clipped in according to the degree of the machine tool chuck, and the G part has threads and knife handle tightening. Through the axial force transmitted by the cnc pull rod, the pull rod joint and the cnc pull stud, the tool holder is tightened. When changing the tool, it is required to loosen the tool holder. When the cnc pull stud is installed on the spindle of the common machine tool or the numerical control machine tool, the arc joint of the rod body is connected with the front end of the pull rod structure. The screw joint of the cnc pull stud is connected with the inner screw hole of the tool holder extending into the spindle hole, thus realizing the use of the tool holder on the common machine tool and the numerical control machine tool. The tool holder can be used not only in machining centers, but also in common machine tools and CNC machine tools, which improves the universality of the tool holder and reduces the production cost.

The cnc pull stud of the tool holder is tightened. When changing the tool, the tool holder should be loosened. The automatic clamping mechanism of the tool inside the spindle is the special mechanism of the CNC machine tool processing center. The drawing shows the structure of the spindle of the machining center. The cutter can be loaded and unloaded automatically on the spindle and clamped automatically. The working principle is as follows: when the cutter 2 is loaded into the spindle hole, the pull pin 3 at the back of the handle is sent to the front of the spindle pull rod. Under the action of the disc spring, the cutter is tightened by the elastic claw.
