Description

Technical Field

[0001] The invention belongs to the technical field of pole needle closing, and in particular relates to an automatic closing device for an open pole needle. Background Art

[0002] The closing method of a cylindrical straight-opening pole pin is as follows: apply pressure from both sides of the pole pin opening toward the center at the same time. When the pressure exceeds the yield strength of the material, the pole pin opening changes from a rigid structure to an inward-retracted elastic structure. The closing requires that the plugging and unplugging force be controlled within a specified range. The closing process is mainly divided into two steps: aligning the opening direction and closing by applying pressure. The closing methods are divided into manual closing and automatic closing: manual closing is completed by manually aligning the opening direction and manually applying pressure, which has the defects of asymmetric closing and large difference in plugging and unplugging force; currently known automatic closings divide the opening direction correction and pressure closing into two steps, and the production efficiency is relatively low.

The photoelectric sensor 11 is cantilevered and installed on the side of the housing 14. The tongue 12 is cylindrical in shape; the outer circle of the tongue 12 and the groove on the outer circle cooperate with the housing 14, and can make axial rotational motion with the housing 14; one end of the tongue 12 is connected to the piston 10, and the other end contacts and cooperates with the opening of the pole needle 13 when working.

[0038] Preferably, the working principle of the pole needle opening correction mechanism is as follows: the telescopic cylinder 4 drives the cylinder connecting rod 5 to push the sliding guide rail 7 to move forward, so that the tongue 12 contacts the end face of the pole needle 13; then the M2 servo motor 6 drives the tongue 12 to rotate through the coupling 8; when the flat square structure of the tongue 12 rotates to the same level as the opening of the pole needle 13, the piston spring 15 pushes the piston 10 to drive the tongue 12 to insert into the opening of the pole needle 13, and at the same time the shell 14 and the tongue 12 move in the same direction; the M2 servo motor 6 drives the shell 14 to rotate together with the tongue 12, and when the photoelectric sensor 11 transmits a signal through the round hole on the piston 10, it indicates that the opening direction of the pole needle 13 has been successfully corrected.

[0039] In this embodiment, if Figure 1 and Figure 2 As shown, the pole needle pressure closing mechanism specifically includes: a closing push rod 1, a screw guide rail 2, an M1 servo motor 3, a jaw 17, a transverse slider 16, a slider spring 18, a longitudinal slider 19 and a guide shaft 20.
