Small milling machine for workpiece positioning

Abstract

The invention discloses a small milling machine for workpiece positioning. The small milling machine comprises a milling machine mechanism, a crane base and a clamp support arranged at one end of the crane base, a fixed clamp and a movable clamp are installed on the clamp support, and the movable clamp is movably installed on the clamp support through a lead screw mechanism; the fixed clamp and the movable clamp are used for clamping a conductor coil, and the movable clamp can move front and back in the Y-axis direction under driving of the lead screw mechanism so as to be matched with the curvature of the conductor coil; the milling machine mechanism is installed on the crane base and used for tapping in the conductor coil winding process. and a plurality of suspension rings are also arranged at the end parts of the crane base and the clamp support. The small milling machine is suitable for machining special workpieces, and compared with existing milling machine equipment, the small milling machine is compact in structure, large in rigidity and high in precision, can meet the working environment requirement of coil winding field tapping, improves the machining precision and efficiency of helium holes, and provides equipment guarantee for superconducting coil helium hole drilling.

Description

Technical field [0001] The present invention relates to the field of milling technology, particularly to small milling A work positioning. Background technique [0002] Currently, in the prior art, the superconducting coil tokamak using conductor wound from CICC, CICC structure refers to a superconducting cable is inserted into the circular outer conductor and then through the armor reduced diameter is formed, and super wire turns during the winding process also requires the molding using supercritical helium forced flow cooling liquid helium is introduced to the interior of the coil, the need to excavate in the racetrack holes helium inside or outside of the coil conductors armor, such as figure 1 . The coil winding process, the opening must be in the winding process, such as figure 2 As shown in this case the conductor presents trends open, the spacing between conductors is usually 400mm, 750mm minimum inner diameter of the conductor, since the small working space field, millin...

Problems solved by technology

According to the coil winding process, the opening must be made during the winding process, such as figure 2 As shown, the conductors show a tendency to open at this time, the distance between the conductors is generally 400mm, and the minimum inner diameter of the conductors is 750mm. Due to the narrow working space on site, the general milling machine equipment on the market cannot solve this problem. less efficient
