Abstract
Claims
1. An auxiliary fixing tool for processing a nipple core, which is used in cooperation with a lathe, characterized in that, Auxiliary fixtures include: The base (2) is used to hold the chuck (5) of the lathe. At least three arc-shaped spring pieces (6) are provided on the side of the base (2) away from the chuck (5). The at least three arc-shaped spring pieces (6) form a hollow tube for embedding in the end cap (1). An embedded block (3) is provided, the outer diameter of which gradually increases along its axis, and the end of the embedded block (3) with a smaller outer diameter is embedded in the hollow tube. A pull rod assembly (4) has one end that slides through the base (2), the hollow tube and the embedded block (3), and the other end that slides through the chuck (5) and is connected to the pull drive component (7) on the lathe.
2. The auxiliary fixing tool for processing of a sock core according to claim 1, characterized in that, The embedded block (3) is conical, and the inner wall of the end of the hollow tube that mates with the embedded block (3) is also conical.
3. The auxiliary fixing tool for processing of a sock core according to claim 1 or 2, characterized in that, The base (2) includes a fixed base (11) and a positioning plate (12) detachably connected to the fixed base (11). The fixed base (11) is clamped in the chuck (5). The hollow tube is disposed on the side of the positioning plate (12) away from the fixed base (11). Both the fixed base (11) and the positioning plate (12) are provided with through holes (8) through which one end of the pull rod assembly (4) passes. The axes of the two through holes (8) are on the same straight line.
4. The auxiliary fixing tool for processing of a sock core according to claim 3, characterized in that, The pull rod assembly (4) includes a first pull rod (41) and a second pull rod (42). One end of the first pull rod (41) is connected to the embedded block (3), and the other end of the first pull rod (41) is threadedly connected to one end of the second pull rod (42). The other end of the second pull rod (42) passes through the chuck (5) and is connected to the pull-back drive member (7).
5. The auxiliary fixing tool for processing of a sock core according to claim 4, characterized in that, The diameter of the through hole (8) in the fixed base (11) is larger than the diameter of the through hole (8) in the positioning plate (12). The first pull rod (41) is fitted with the through hole (8) in the positioning plate (12) with clearance, and one end of the second pull rod (42) is fitted with the through hole (8) in the fixed base (11) with clearance.
6. The auxiliary fixing fixture for machining the blind core according to claim 4 or 5, characterized in that, The outer edge of one end of the second tie rod (42) is provided with a stepped surface (10) along its circumference, or the outer edge of one end of the second tie rod (42) is provided with a rounded corner.
7. The auxiliary fixing tool for processing of a sock core according to claim 6, characterized in that, The embedded block (3) has an internal hexagonal hole (9) on the end face away from the first pull rod (41).
