Tool for measuring size of automobile suspension

Abstract

The invention discloses a tool for measuring the size of an automobile suspension. A suspension limiting seat is fixed on a pedestal, the upper top surface of the suspension limiting seat is providedwith a limiting groove matched with a suspension lower housing, and the suspension is embedded into the limiting groove through the suspension lower housing and is horizontally placed on the suspension limiting seat; the pressing mechanism is arranged on the rear side of the suspension limiting base and used for pressing the suspension on the suspension limiting base. The pre-pressing mechanism comprises pre-pressing assemblies symmetrically arranged on the two sides of the suspension limiting base and used for preliminarily pressing the suspension on the suspension limiting base, and after the pressing mechanism presses the suspension, the pre-pressing assemblies reset. The tool has the advantages that the horizontal pressing better simulates the loading posture of the suspension, effectively prevents the suspension from inclining, avoids the measurement error caused by the fact that the support arm does not sink in the direction of the loading posture, and is beneficial to improvingthe measurement precision; the pre-pressing mechanism is convenient for the pressing mechanism to press and suspend, so that the operation is convenient; after the pressing mechanism presses the suspension, the pre-pressing assembly resets, subsequent testing is not affected, and the testing precision can be improved.

Description

technical field [0001] The invention relates to the field of dimension measuring tooling for auto parts, in particular to a tooling for measuring the size of an automobile suspension. Background technique [0002] The suspension of the automobile powertrain plays an important role in the shock absorption and noise reduction of the whole vehicle. The contours of mounts are diverse in practical applications. In order to ensure the positioning accuracy during installation, the measurement of their dimensions is extremely important. During the measurement process, in order to facilitate the placement of various features, the requirements for the measurement tooling are very high. [0003] Existing measuring tooling generally includes a support column, an upper clamp arm and a lower clamp arm. The upper clamp arm and the lower clamp arm are symmetrically fixed on the outer wall of the support column, suspended and clamped between the upper clamp arm and the lower clamp arm. The ...

AI Technical Summary

Problems solved by technology

Although the measuring tool with this structure can clamp the suspension, the upper clamping arm and the lower clamping arm respectively clamp the outer wall of the suspension shell, and the clamping surface is limited, which may easily cause the suspension to tilt to one side, resulting in a gap between positioning. Hole distance measurement error

In addition, due to the gravity of the support arm itself, vertical placement is likely to cause the support arm to move down in the direction of the loading posture, resulting in an error in the distance between the support arm hole and the positioning hole of the suspension shell.
