Description

Technical Field

[0001] The utility model relates to the field of front axle inspection tools, in particular to an upper left inspection tool for a front axle of an automobile. Background Art

[0002] The front axle is a device for transmitting the directional forces between the frame and the front wheels and the bending moments and torques generated therefrom. The axle is connected to the frame through the suspension, with wheels mounted at both ends. The vertical load on the frame is transmitted to the wheels through the axle; the rolling resistance, driving force, braking force and lateral force on the wheels and their bending moments and torques are transmitted to the suspension and frame through the axle. Therefore, the function of the axle is to transmit the directional forces between the frame and the wheels and the bending moments and torques generated therefrom. The front axle is generally located at the front of the car, also known as the steering axle or driven axle. The front axle is an important assembly on the car, and many of the accessories that make up the front axle of the car require through-hole position detection during the production and processing process.

[0003] A Chinese patent with announcement number CN219890314U discloses an upper left inspection fixture for a front axle of an automobile, comprising a base and a hollow support platform, wherein the hollow support platform is fixed to the front side of the top end of the base, and the upper left accessory of the front axle of the automobile can be placed on the hollow support platform. The fixture also comprises a right-angle mounting plate, a lifting mechanism, a rotating disk, a rotating mechanism, multiple groups of detection modules and an adsorption mechanism, wherein the right-angle mounting plate is fixed to the rear side of the top end of the base, and the lifting mechanism is mounted on the right-angle mounting plate, wherein the lifting mechanism is used to drive the rotating disk and the rotating mechanism to move up and down, and the rotating mechanism is used to drive the rotating disk to rotate. However, the upper left inspection fixture for a front axle of an automobile in the above patent can only detect one upper left accessory of the front axle at a time, and the detection is relatively troublesome, thereby reducing the detection efficiency of the upper left accessory of the front axle. Therefore, a person skilled in the art provides an upper left inspection fixture for a front axle of an automobile to solve the problems raised in the above background technology.
