Description
Technical Field
The invention relates to the technical field of machinery, in particular to a barrel-shaped nut mounting tool and a using method thereof.
Background
Chinese utility model patent CN2849294 discloses a barrel-shaped auto-lock nut connecting piece, and its technical scheme is: the support is a semi-barrel body with the shape and the size generally consistent with those of the holes to be connected, two end planes of the barrel body radially extend to form a U-shaped through groove, a bolt through hole is formed in the groove, a nut supporting seat is assembled on the step surface of the U-shaped through groove and is matched with a self-locking nut with the diameter and the size generally consistent with those of the through groove, and an elastic opening shell body retainer with an arc-shaped bent edge and a generally rectangular hole formed at the bottom is clamped on the two end planes of the barrel body.
The barrel-shaped self-locking nut connecting piece needs to be installed in production. When the barrel-shaped self-locking nut connecting piece is installed, the barrel-shaped self-locking nut connecting piece needs to be integrally installed in a hole of a frame structure. The specific installation process is as follows:
the barrel-shaped nut retainer is sleeved on the barrel-shaped nut and the support, and the position state of the barrel-shaped nut relative to the structural bolt mounting hole is adjusted: the nut support is close to one side of the structure bolt hole, the axis direction of the nut hole is parallel to the axis direction of the structure bolt hole, and after the nut is confirmed to be correct in direction, the nut and the retainer are pushed into the structure mounting hole by pressing the retainer arch edge with hands.
In the actual installation process, the retainer of the barrel-shaped nut plays the role of a special-shaped spring piece, so that the nut component is supported in the installation hole and does not slide out. The actual arched edge of the upper half part of the retainer does not completely follow the cambered surface of the inner hole, and the arched edge protrudes upwards to provide a certain elastic supporting force. The arched edge of the retainer is manually pressed before installation, and then the assembly is integrally sent into the installation hole. However, the arched edge is very difficult to operate and press by hand in practice because of its thick thickness and short length. Even an operator forcibly beats the arched edge to cause the arched edge to be over-pressed and even deformed, so that the arched edges are mutually overlapped in an interference manner.
Therefore, the special mounting tool for the barrel-shaped nut is designed, and the operation is convenient and simple. The barrel-shaped nut can be quickly installed in place, and the difficulty of field manual installation is avoided.
