Auxiliary installation tool and method for U-bolt upper penetration installation

Abstract

The invention discloses an auxiliary installation tool and method for upper-passing installation of U-shaped bolts, belonging to the technical field of vehicle maintenance, comprising: a left clamp body and a right clamp body symmetrically arranged relative to a hinge point P; A left jaw, a second left jaw, and a left jaw handle, the right jaw body includes a first right jaw, a second right jaw, and a right jaw handle connected in sequence, and the hinge point P is located at the left jaw handle and the right jaw At the intersection of the top of the handle, the bottom of the left clamp handle and the right clamp handle are connected by a spring; the inner sides of the first left clamp claw and the first right clamp claw are oppositely provided with two first jaws, the second left clamp claw and the second The inner side of the right jaw is oppositely provided with two second jaws. The beneficial effects of the invention are as follows: the labor intensity can be reduced and the installation efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle maintenance, in particular to an auxiliary installation tool and method for U-shaped bolts to be installed through top. Background technique [0002] The vehicle chassis is provided with a balanced suspension, which generally includes components such as a balance shaft, a leaf spring, a spring cover (or base), U-shaped bolts, and nuts as U-shaped bolt accessories. When assembling the balanced suspension, it is necessary to connect the leaf spring and the spring cover plate through U-shaped bolts, so that the leaf spring and the spring cover plate are assembled on the balance shaft. [0003] At present, there are two ways to install the U-bolts of the balance suspension in the industry. One is that the U-bolts are passed down. The other is U-shaped bolts, which need to be aligned with the holes of the leaf spring cover. Since the spring cover is a movable part, it is not easy to align the U-shaped...

Problems solved by technology

Before installing obliquely upwards, it is necessary to adjust the U-shaped bolts to a second angle relative to the vertical direction (the first angle is smaller than the second angle, for example, the first angle = 80°, the second angle = 82°) to align with the installation hole, However, due to the limited gap between the U-shaped bolt and the leaf spring and the spring cover is a movable part, it is difficult for the operator to adjust the angle of the U-shaped bolt, which makes it difficult to align the holes, resulting in high labor intensity and low efficiency.

[0006] (2) After the U-bolt passes through the mounting hole of the spring cover plate, the nut needs to be installed. Due to the gravity of the U-bolt itself, it is necessary to continue to hold the U-bolt by hand until the U-bolt and the nut are screwed on. people cannot move
