The base member may be any member having a hole, for example, the base member may be a body of a mule car in an automobile manufacturing process, or may be a member required to be used as a mounting reference member in another car.
The first datum point refers to a reference position, and the specific form of the first datum point can refer to a hole or a point with the area approaching 0; the second datum point is a machining position which has a preset specific position relation with the first datum point, and a hole or a groove can be machined at the machining position subsequently, or other parts can be installed at the machining position. The first flexible body of the first scale 13 is a linear flexible body, which can be made of a material that is easy to bend but has elasticity meeting the requirement, so that the first flexible body 13 can be wound in the first accommodating cavity; when the second reference portion 12 moves away from the first reference portion 11, the first flexible body can be pulled out from the first accommodating cavity, and the scale marks on the first flexible body can accurately indicate the distance between the second reference portion 12 and the first reference portion 11.
The specific process for determining the second reference point by using the measuring and positioning tool for automobile machining provided by the embodiment may include: firstly, matching a first reference end 112 with a first hole, wherein at the moment, the corresponding position of the first reference end 112 is the position of a first reference point; then, the second reference part 12 is pulled to enable the first flexible body to extend out of the first reference part 11, as the second reference part 12 is gradually far away from the first reference part 11, the part of the first flexible body extending out of the first accommodating cavity is gradually increased, the scale on the first flexible body is closely concerned in the process, when the preset value is reached, the position of the second reference end of the second reference part 12 is the second reference point, and then, other parts can be further processed or installed at the second reference point according to needs.
of course, the measuring and positioning tool for automobile machining provided by the embodiment is not limited to the above-mentioned manner, and may be used simply as a measurement. For example, it can be used to measure the distance between a hole on the base member and the object to be measured, the specific process is similar to the process of determining the second reference point, except that the hole or other component is already provided at the second reference point, the second reference portion 12 only needs to be matched with the hole or aligned with the reference point of other component, and then the scale value on the first flexible member 10 is read under the condition that the first reference portion 11 and the second reference portion 12 are at the same horizontal position, so as to obtain the relative position parameter of the second reference point with respect to the hole.

When the first reference end 112 of the first reference portion 11 is placed in one hole in the base member, the first axial center line may be made to coincide with the center line of the hole, and at this time, a projection point of the first axial center line and the center line of the first hole on the base member may be used as the first reference point. Similarly, the second axial centerline may also be used to coincide with the central axis or point of the hole or part to be measured to further improve positioning accuracy.
On the basis of the above embodiments, the second reference end 122 can also be configured into different structures according to the measurement or positioning requirements of specific needs. For example, second reference end 122 is tapered with a tip portion 123, and tip portion 123 is located on a second axial centerline.
Specifically, the tip portion 123 is made of a hard material such as: the material of the tip portion 123 is diamond.
At this time, the second reference terminal 122 can achieve more accurate determination of the position of a point on the reference member whose area approaches 0. The specific operation process can be as follows;

The first scale 13 displays a scale as a distance L1 between the first reference part 11 and the second reference part 12, and the distance between the first hole and the point to be measured can be obtained according to the distance L1.
For another example, fig. 2 is a structural diagram of a first flexible component of a measurement and positioning tool for automobile machining according to another embodiment of the present invention; referring to fig. 2, an end surface of the second reference end 122 may be a plane, that is, the bottom end of the second reference end 122 is blunt. The second reference end 122 of the structure can more accurately realize the positioning of the other second hole on the reference component, namely accurately measure whether the position of the other second hole on the reference component relative to the existing first hole is in accordance with the requirement. Specifically, the method comprises the following steps:
Mating the first reference end 112 with a first hole, the first axial centerline coinciding with the centerline of the first hole, the first axial centerline defining a first reference point; pulling the second reference portion 12, the first flexible body of the first scale 13 extending out of the first reference portion 11; the second datum end 122 is mated with the second hole with a second axial centerline coincident with the centerline of the second hole, the second axial centerline defining a second datum point. The first scale 13 displays a scale indicating a distance L1 between the first reference part 11 and the second reference part 12, and the distance between the first hole and the second hole can be obtained from the distance L1.
Preferably, referring to fig. 3, fig. 3 is a structural diagram of a first flexible part 10 of a measuring and positioning tool for automobile machining according to another embodiment of the present invention; the structure of the second reference terminal 122 can be further optimized as follows: comprises a columnar upper end part 124 and a lower end part 125 arranged below the upper end part 124, wherein the lower end part 125 is a cone with a tip part 123, and the tip part 123 is positioned on a second axial central line.

The second flexible body of the second scale 23 may adopt the same structure as the first flexible body of the first scale 13. When the matching part 22 moves away from the third reference part 21, the second flexible body can be pulled out from the second accommodating cavity, and the scale marks on the second flexible body can accurately indicate the distance between the matching part 22 and the third reference part 21. After the matching portion 22 is matched with the second reference portion 12 of the first flexible member 10, since the scale marks on the second flexible body also indicate the distance between the second reference portion 12 and the third reference portion 21, the positions of the second reference portion 12 relative to the first reference point and the third reference point can be conveniently determined, that is, another position which is a preset distance relative to the first reference point and the third reference point can be accurately determined at one time.
