Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The barrel-shaped nut mounting tool is characterized by comprising a beam-shaped shell and a push rod 3, wherein the outer diameter of the output end of the push rod 3 is smaller than the inner diameter of the beam-shaped shell, the push rod 3 is inserted into a cavity of the beam-shaped shell, a nut workpiece group is arranged in the beam-shaped shell, and the push rod 3 is in butt joint with the nut workpiece group arranged in the beam-shaped shell.
The beam-shaped shell is a beam-shaped supporting structure formed by two equal-diameter semicircular cylinders and consists of a first shell 1 and a second shell 2, and connecting lug plates 5 are arranged at the end parts of the first shell 1 and the second shell 2.
The connecting lug plate 5 is provided with a threaded through hole, and the first shell 1 and the second shell 2 are in threaded connection through installing a fastening bolt on the threaded through hole of the connecting lug plate 5.
A limiting boss 6 is axially arranged at the middle position of the cavity of the first shell 1.
The nut workpiece group consists of a barrel-shaped nut 4 and a retainer 8, wherein the barrel-shaped nut 4 is a connecting structure with internal threads formed in the radial direction of a cylinder body, and the retainer 8 is arranged at the upper end of a threaded hole of the barrel-shaped nut 4.
The retainer 8 is a supporting structure formed by upward bending at the two transverse ends and downward bending at the two longitudinal ends, an opening 9 is formed between the upward bending ends of the retainer 8, mounting plates 10 are formed at the downward bending ends of the retainer 8, and a through hole matched with the threaded hole of the barrel nut 4 is formed in the middle position of the opening 9.
The outer diameter of the opening 9 formed by bending the retainer 8 upwards is slightly larger than the inner diameter of the cavity of the first housing 1 in actual production, and in the process of combining the first housing 1 and the second housing 2 through the connecting lug plate 5, the first housing 1 extrudes the retainer 8 so that the retainer 8 deforms and is converged into the converging housing.
The limiting boss 6 arranged in the first shell 1 is embedded in the opening 9, and the inner wall of the mounting plate 10 is abutted with the end part of the barrel nut 4.
The ejector rod 3 is of a hollow cylinder structure, an axial positioning groove 7 is formed in the outer outline of the ejector rod 3, and a sinking groove 11 matched with the mounting plate 10 is formed in the end portion of the ejector rod 3.
