TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile size measurement, more particularly to an automobile space size measurement auxiliary tool. BACKGROUND
[0002] Automobile production is a highly precise process involving thousands of parts and complex assembly processes. In order to ensure that the design, performance and safety of each vehicle meet the standards, strict measurement and control of key dimensions must be carried out. Wheelbase, track and car width are the core parameters of vehicle geometry, which directly affect the controllability, stability, space layout and appearance design of the vehicle. Therefore, accurate measurement of these dimensions is an important part of quality control during production.
[0003] In the prior art, the method for measuring the key dimensions of an automobile is that an operator holds a silk thread connected with a plumb bob beside the automobile hub, adjusts the plumb bob to be perpendicular to the ground, visually judges whether the vertical line passes through the hub center, and if so, marks the center point at the contact point of the plumb bob and the ground. Then the same method is used to mark the center points of the other three hubs in turn, and finally a steel tape measure is used to measure the distance between two different mark points to obtain the wheelbase, track and car width.
[0004] However, there is no clear mark at the hub center point for reference, which needs to be determined by human judgment. It takes a lot of time to determine the hub center point manually, resulting in a long time for the entire measurement task. Moreover, there is a large error in determining the hub center point manually, resulting in inaccurate measurement of the wheelbase, track and car width. SUMMARY
[0005] In view of the problem that there is no clear mark at the hub center point in the prior art, which leads to slow judgment of the center point and large error, the utility model provides an automobile space size measurement auxiliary tool, which helps to improve the speed of manual judgment of the hub center point and reduce the judgment error.
[0006] To solve the above technical problems, the technical scheme provided by the utility model is:
[0007] An automobile space size measurement auxiliary tool, comprising a tool main body, at least two positioning inserts for inserting into the automobile hub mounting holes are arranged on one side of the tool main body, a scale disc is arranged on the other side of the tool main body, and the positioning inserts are distributed in a circular array around the axis of the scale disc. It can be understood that the scale disc is a disc surface structure provided with scale lines, and the scale lines are uniformly distributed on the scale disc in a circular array. Of course, the scale disc can also be provided with two scale lines that pass through the center of the scale disc and are perpendicular to each other, which can facilitate the silk thread to quickly align with the center of the scale disc.
[0008] The technical scheme has the advantages that the positioning insert is inserted into the mounting hole of the automobile wheel hub first, so that the tool body is quickly and stably installed on the wheel hub, then the operator holds the silk thread connected with the plumb bob, lets the silk thread naturally drop, moves the silk thread to coincide with the vertical scale line on the scale disc as the reference, and determines that the silk thread coincides with the center of the automobile wheel hub, then marks the center point at the contact point of the plumb bob and the ground, and then marks the center points of the other three wheel hubs in sequence by using the same method, and finally measures the distance between two different mark points by using the steel tape, so that the wheelbase, the track and the vehicle width are obtained.
[0009] Preferably, the tool body further comprises a housing connected with the scale disc and forming a liquid cavity therebetween. The liquid cavity is filled with colored liquid, and the volume of the colored liquid is half of the volume of the liquid cavity. If the tool is not installed horizontally, the liquid surface in the liquid cavity will be inclined, so that the reference of the scale disc and the silk thread is inaccurate, and finally the positioning of the center of the wheel hub and the measurement results of the wheelbase, the track and the vehicle width are affected. The operator can adjust the tool body based on the liquid surface in the liquid cavity, so that the liquid surface of the colored liquid coincides with the horizontal scale line on the scale disc, and then the position of the silk thread is adjusted, which is beneficial to improve the accuracy of the measurement results.
[0010] Preferably, the scale disc is rotationally connected with the tool body, and the rotation axis of the scale disc is the self-axis. In use, the operator can rotate the scale disc, so that the 0° scale line on the scale disc is rotated to the horizontal state. If the liquid surface in the liquid cavity coincides with the 0° scale line, it indicates that the tool body is in the horizontal state. At this time, the 90° scale line is in the vertical state, and the 90° scale line is the position reference of the silk thread. Since the 0° scale line and the 90° scale line are the more conspicuous scale lines on the scale disc, the scale disc is arranged in the rotatable form, so that the operator can quickly adjust the scale disc to zero, and quickly determine whether the liquid in the liquid cavity is horizontal and quickly find the position reference of the silk thread, which is beneficial to improve the efficiency of operation and the accuracy of the measurement results.
[0011] Preferably, the positioning insert is provided with a receiving cavity for the bolt in the mounting hole of the automobile wheel hub. In the case of vehicle movement or external vibration, the cooperation between the receiving cavity and the bolt can maintain the stability of the tool.
[0012] Preferably, the outer side of the positioning insert is provided with a soft rubber layer. The soft rubber layer can avoid the direct contact between the positioning insert and the surface of the wheel hub, and reduce the risk of scratching or damaging the wheel hub. Moreover, the larger friction force of the soft rubber layer on the automobile wheel hub can prevent the tool body from sliding or shifting after installation.
[0013] Preferably, three positioning inserts are provided. The three positioning inserts form a stable triangular support structure, which can ensure a stable connection between the tool body and the wheel hub, and avoid shaking or tilting. Moreover, compared with a larger number of positioning inserts, the three positioning inserts are easier to align, and the installation complexity is reduced.
[0014] Preferably, the tool body is disc-shaped, and the axis of the dial is coincident with the axis of the tool body. The disc-shaped structure makes the tool body bear force evenly after installation, and reduces shaking or tilting caused by uneven force.
[0015] Preferably, the positioning inserts and the tool body are both made of stainless steel. Stainless steel has high strength and hardness, can withstand a large external force without deformation, and ensures that the tool remains stable in shape when subjected to bumps during long-term use. Moreover, stainless steel is more durable, and still has a high service life under frequent use and harsh environments.
[0016] Preferably, the positioning inserts and the tool body are welded as a whole. The welded connection method can make the structure of the tool more compact, and reduce the setting of connecting parts.
[0017] In another preferred embodiment, the positioning inserts are magnetic parts. The magnetic parts can be firmly attracted to the automobile wheel hub mounting hole, ensuring that the tool does not shake or shift during measurement, and facilitating the improvement of measurement accuracy.
[0018] The utility model discloses the beneficial effects of the following:
[0019] 1. By setting the positioning inserts and the dial on the tool body, the positioning inserts can cooperate with the automobile wheel hub mounting hole to make the dial stable on the automobile wheel hub. The dial provides clear reference lines for the operator, facilitates the operator to quickly find the center of the automobile wheel hub, reduces the dependence on the operator's experience, avoids human judgment errors, and ensures more accurate measurement results. Moreover, the operator does not need to repeatedly adjust the silk thread and visually judge, the operation is simplified, the measurement time can be significantly shortened, and the work efficiency is improved.
[0020] 2. The dial is connected to the shell to form a liquid cavity, the liquid cavity is used to fill colored liquid, and the operator can adjust the tool body based on the liquid level in the liquid cavity, so that the liquid level of the colored liquid coincides with the horizontal scale line on the dial, and then the silk thread position is adjusted. This is beneficial to improve the accuracy of the measurement results.
[0021] 3. The dial is rotatable, which facilitates the operator to quickly zero the dial, so as to quickly judge whether the liquid in the liquid cavity is horizontal, and quickly find the position reference datum of the silk thread, which is beneficial to improve the efficiency of operation and the accuracy of measurement results.

[0028] The technical scheme of the present application will be further described in detail below through specific embodiments, and in conjunction with the drawings:
[0029] Embodiment 1
[0030] The present embodiment is a first embodiment of an automobile space size measurement auxiliary tool, which is combined with Figs. 1 to 3 As shown in the drawings, it comprises a tool body 1, three positioning inserts 2 for inserting the automobile hub mounting hole are arranged on one side of the tool body 1, and the positioning inserts 2 are in cylindrical shape; a dial 3 is arranged on the other side of the tool body 1, and the positioning inserts 2 are distributed in a circle with the axis of the dial 3 as the array axis. The three positioning inserts 2 form a stable triangular support structure, which can ensure the stable connection between the tool body 1 and the hub, and avoid shaking or tilting. Moreover, compared with a larger number of positioning inserts 2, the three inserts are easier to align, reducing the installation complexity.
[0031] Specifically, the three positioning inserts 2 are distributed in a non-uniform circumferential manner. The included angle between the positioning insert 2 located at the top of the tool body 1 and the two positioning inserts 2 located at the bottom of the tool body 1 is 144°, and the included angle between the two positioning inserts 2 located at the bottom of the tool body 1 is 72°.
[0032] The prior art automobile hub is generally provided with five hub mounting holes for mounting bolts, and the five hub mounting holes are uniformly distributed on the automobile hub with the center line of the automobile hub as the array center. Therefore, after the positioning insert 2 is inserted into the automobile hub mounting hole, the center of the dial 3 is also the center of the automobile hub. It can be understood that the dial 3 is a disc structure provided with scale lines, and the scale lines are uniformly distributed on the dial 3. In this embodiment, the 0° scale line and the 90° scale line on the dial 3 are relatively long, and both pass through the center of the dial 3, so that the silk thread can be quickly aligned with the center of the dial 3.
[0033] Further, the positioning insert 2 is provided with a receiving cavity 201 for the bolt in the automobile hub mounting hole to extend into. In the case of vehicle movement or external vibration, the cooperation between the receiving cavity 201 and the bolt can maintain the stability of the tool.
[0034] Further, the tool body 1 is disc-shaped, and the axis of the dial 3 coincides with the axis of the tool body 1. The disc-shaped structure makes the tool body 1 uniformly stressed after installation, reducing the shaking or tilting caused by uneven stress.
[0035] Further, the positioning insert 2 and the tool body 1 are both made of stainless steel. Stainless steel has high strength and hardness, can withstand a large external force without deformation, and can ensure that the tool remains stable in shape when subjected to bumps during long-term use. Moreover, stainless steel is more durable and still has a relatively high service life under frequent use and harsh environments.
[0036] Further, the positioning insert 2 and the tool body 1 are welded together. The welding connection method can make the structure of the tool more compact, reducing the setting of connecting parts.
[0037] The working principle or working process of the embodiment is as follows: in implementation, the positioning insert 2 is first inserted into the automobile hub mounting hole, thereby quickly and stably installing the tool body 1 on the hub. Then, the operator holds the silk thread connected with the plumb bob, lets the silk thread naturally drop, moves the silk thread to coincide with the vertical scale line on the dial 3 with the vertical scale line on the dial 3 as the reference, at which time it can be determined that the silk thread coincides with the center of the automobile hub; then, the contact point between the plumb bob and the ground is marked as the center point; then, the same method is used to sequentially mark the center points of the other three hubs, and finally the distance between the two different mark points is measured with a steel tape measure, thereby obtaining the wheelbase, track, and vehicle width.
[0038] The beneficial effects of the embodiment: by setting the positioning insert and the scale disc on the tool body, the positioning insert can cooperate with the automobile hub mounting hole to make the scale disc stable on the automobile hub, and the scale disc provides clear reference lines for the operator to quickly find the center of the automobile hub, which can reduce the dependence on the operator's experience, avoid human judgment errors, and ensure more accurate measurement results. Moreover, the operator does not need to repeatedly adjust the silk thread and visually judge, the operation is simplified, the measurement time can be significantly shortened, and the work efficiency is improved.
[0039] Embodiment 2
[0040] The second embodiment of the automobile space size measurement auxiliary tool, which is further improved on the basis of the scheme of embodiment 1.
[0041] In combination with Fig. 2 and Fig. 3 , the tool of the embodiment further includes a transparent shell 4 connected with the scale disc 3 and forming a liquid cavity therebetween. The liquid cavity is used to fill colored liquid, and the volume of the colored liquid is half of the volume of the liquid cavity. If the tool is not installed horizontally, the liquid surface in the liquid cavity will be inclined, resulting in inaccurate reference datum of the scale disc 3 and the silk thread, and ultimately affecting the positioning of the hub center point and the measurement results of the subsequent wheelbase, track, and vehicle width. The operator can adjust the tool body 1 based on the liquid surface in the liquid cavity, so that the liquid surface of the colored liquid coincides with the horizontal scale line on the scale disc 3, and then adjust the position of the silk thread, which is conducive to improving the accuracy of the measurement results.
[0042] Further, the scale disc 3 is rotationally connected with the tool body 1, and the rotation axis of the scale disc 3 is the self-axis. When in use, the operator can rotate the scale disc 3 to rotate the 0° scale line on the scale disc 3 to the horizontal state, and if the liquid surface in the liquid cavity coincides with the 0° scale line, it indicates that the tool body 1 is in the horizontal state. At this time, the 90° scale line is in the vertical state, and the 90° scale line is the position reference datum of the silk thread. Since the 0° scale line and the 90° scale line are the more conspicuous scale lines on the scale disc 3, the scale disc 3 is set to be rotatable, which can facilitate the operator to quickly zero the scale disc 3, so as to quickly judge whether the liquid in the liquid cavity is horizontal and quickly find the position reference datum of the silk thread, which is conducive to improving the efficiency of operation and the accuracy of the measurement results.
[0043] Further, the outer side of the positioning insert 2 is provided with a soft rubber layer (not shown in the figure). The soft rubber layer can avoid direct contact between the positioning insert 2 and the hub surface, reducing the risk of scratching or damaging the hub. Moreover, the larger friction of the soft rubber layer on the automobile hub can prevent the tool body 1 from sliding or shifting after installation.
[0044] Other features, principles and advantages of the embodiment are the same as those of embodiment 1.
[0045] Embodiment 3
[0046] The third embodiment of the application is a third embodiment of an auxiliary tool for measuring the size of a vehicle space, which is similar to the second embodiment, except that the positioning insert 2 is a magnetic member. The magnetic member can be firmly attracted to the mounting hole of the vehicle hub, ensuring that the tool does not shake or shift during the measurement process, thereby improving the measurement accuracy.
[0047] Other features, principles and advantages of the embodiment are the same as those of embodiment 2.
[0048] In the specific contents of the above specific embodiments, any technically consistent combination of technical features can be made, and in order to make the description concise, all possible combinations of the above technical features are not described, but as long as the combination of technical features does not exist, it should be considered as the scope of the present application.
[0049] Obviously, the above embodiments of the application are only examples for clearly illustrating the application, and are not intended to limit the embodiments of the application. For those skilled in the art, other different forms of changes or modifications can be made on the basis of the above description, and all these changes and modifications are not required to be enumerated here. Any modification, equivalent replacement and improvement within the spirit and principle of the application shall be included in the protection scope of the claims of the application.
