Problems solved by technology

However, in the prior art, the distance of the mounting holes is roughly measured, so that when standard parts such as screws are passed through the mounting holes for fixing, the mounting holes of the rear suspension beam and the frame do not correspond to each other, resulting in a loss of vehicle quality. reduce

Embodiment 1

[0016] Example 1, such as figure 1 As shown, the measuring tool for detecting the distance between the mounting holes of the rear suspension beam of the automobile includes a measuring tool body 1, the measuring tool body 1 is in a rectangular shape as a whole, and the length of the measuring tool body 1 is 2000 mm, which is compatible with the length of the rear suspension beam. The lower end of the measuring tool body 1 is fixed with two support frames 2 by bolts, so as to keep the measuring tool body 1 level with the ground and ensure the accuracy of the measuring tool test results. One end of the measuring tool body 1 is fixedly connected with a fixed rod 3. The top of the fixed rod 3 is conical. 5 is threadedly matched with the screw thread of the fixing rod 3, and the fixing rod 3 presses the rubber 4 through the nut 5 to make it interference fit with the mounting hole. The measuring tool body 1 is provided with a chute 6, and the chute 6 is slidably connected with the ...

Embodiment 2

[0017] The difference between Embodiment 2 and Embodiment 1 is that the length of the measuring tool body 1 is 2300 mm.

Embodiment 3

[0018] The difference between Embodiment 3 and Embodiment 1 is that the length of the measuring tool body 1 is 2500 mm.

[0019] First place the rear suspension beam on the horizontal frame, first pass the top of the fixed rod 3 through a hole, rotate the nut 5 downwards, and then deform the rubber 4 to both sides, and the rubber 4 has an interference fit with its mounting hole. Since the rubber 4 is circumferentially arranged around the fixed rod 3, it is located at the center of the circle. Thus, the position of the top of the fixed rod 3 accurately locates the center of the circle of the installation hole. Simultaneously, slide the slide bar 7 to make it interference fit with another installation hole, so as to determine its center of circle. In this way, the distance between the tops of the fixed bar 3 and the slide bar 7 on the reading scale reticle 8 is the distance between the centers of the two mounting holes.

Abstract

The invention relates to the field of automobile detection, and particularly relates to an automobile rear cantilever mounting hole distance detection measurement tool, which comprises a measurement tool body. The overall measurement tool body is rectangular; a fixing rod and a sliding rod in sliding connection are arranged on the measurement tool body; top parts of the fixing rod and the sliding rod are conical; the fixing rod and the sliding rod are circumferentially sleeved with an elastic layer with a uniform thickness; the fixing rod and the sliding rod press the elastic layer via nuts; the side surface of the measurement tool body is provided with a scale reticle plate; and the starting point of the scale reticle plate is located at the place wherein a top rod at one side is connected with the measurement tool body. Through precisely positioning circle centers of two holes, the distance between the two hole centers is detected, and the mounting hole of the automobile rear cantilever and the corresponding mounting hole of a frame can be ensured to be fully coincident.

Description

technical field [0001] The invention relates to the field of automobile detection, in particular to a measuring tool for detecting the distance between mounting holes of an automobile rear suspension beam. Background technique [0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the auto industry, which is in full swing, requires a strong component system to support it. Automobile self-owned brand and technological innovation need parts and components as the basis, and the independent innovation of parts and components will generate a strong impetus to the development of the whole vehicle industry. Without the support of a strong component system, it will be difficult for independent brands to grow stronger. [0003] Suspension system is an important assembly in a car, which elastically conne...
