Description

Technical Field

[0001] This application relates to the technical field of vehicle bodies, and particularly relates to a hinge assembly detection tooling and a detection method. Background Art

[0002] Doors of most vehicles, such as side-opening doors, double-leaf doors, and gull-wing doors, etc., are rotationally connected to the vehicle body through two hinges arranged at intervals. Among them, according to the door installation requirements, the distance and coaxiality between the two hinges need to meet the design conditions. If the distance or coaxiality between the two hinges does not meet the design requirements, it will affect the assembly accuracy of the door, resulting in situations such as the door shifting during installation, being unable to close precisely with the vehicle body after assembly, abnormal noise during door opening and closing, and the hinge being prone to breakage.

[0003] In the prior art, a rod-shaped scale with graduations is usually used to penetrate through the two hinges. An operator holds the scale by hand and obtains the distance between the two hinges by reading the graduations on the scale, and simply evaluates the coaxiality between the two hinges through the penetration state of the scale in the two hinges. It is found during the detection process that during the process of an operator holding the scale by hand to read the value, the scale is prone to shift along the axial direction of the hinge, and the error of manually evaluating the coaxiality is relatively large, which cannot guarantee the detection accuracy of the distance and coaxiality between the two hinges. In addition, after manually reading the value, it is necessary to calculate the difference between the actual distance between the two hinges and the design dimension to determine whether the distance between the two hinges meets the design requirements, resulting in low detection efficiency.

[0045] In order to more clearly understand the above-mentioned objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0046] In the following description, many specific details are set forth in order to fully understand the present disclosure, but the present disclosure may be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all the embodiments.

[0047] It should be noted that in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the existence of additional identical elements in the process, method, article or device comprising the element.

[0048] Such as Figures 1 to 3As shown in the figure, the present application provides a hinge assembly detection tooling. The hinge assembly detection tooling includes a measuring rod 1, a limiting head 2, and a movable measuring member 3.

[0049] A scale is provided along the axial direction of the measuring rod 1 for detecting whether the distance between the first hinge 6 and the second hinge 7 is qualified.

[0050] The limiting head 2 is connected to the first end of the measuring rod 1. Along the radial direction of the measuring rod 1, the size of the limiting head 2 is larger than that of the measuring rod 1, so that a first limiting surface 4 facing the measuring rod 1 is formed at the connection between the limiting head 2 and the measuring rod 1. During the detection process, the first limiting surface 4 can abut against the first hinge 6 to position the relative positions of the measuring rod 1, the first hinge 6, and the second hinge 7, so as to prevent the measuring rod 1 from moving axially in the direction close to the second hinge 7 and affecting the detection accuracy.

[0051] The movable measuring member 3 is slidably sleeved on the measuring rod 1 along the axial direction of the measuring rod 1. Optionally, the measuring rod 1 is a cylindrical rod body, and the movable measuring member 3 is in the form of a cylindrical sleeve structure and is movably sleeved on the measuring rod 1. The inner surface of the movable measuring member 3 is in close contact with the outer surface of the measuring rod 1, so that the movable measuring member 3 can only move along the axial direction of the measuring rod 1, reducing the situation that the measuring rod 1 deflects radially during the detection process and affecting the measurement accuracy.

[0052] The movable measuring member 3 includes an adjacent positioning portion 31 and a measuring portion 32. A second limiting surface 5 is formed at the connection between the positioning portion 31 and the measuring portion 32. The second limiting surface 5 has the same orientation as the first limiting surface 4. During the detection process, the second limiting surface 5 can abut against the second hinge 7 to position the relative positions of the measuring rod 1, the first hinge 6, and the second hinge 7, so as to prevent the measuring rod 1 from moving axially in the direction close to the second hinge 7 and affecting the detection accuracy.

[0053] A positioning member 33 is provided between the positioning portion 31 and the measuring rod 1 to fix the relative positions between the movable measuring member 3 and the measuring rod 1.

[0054] A scale is provided along the axial direction of the measuring rod 1 on the measuring portion 32. The scale on the measuring portion 32 has the same unit as the scale on the measuring rod 1, so that during the measurement process, the numerical values obtained by reading the two scales have the same unit, which is convenient for the staff to count and calculate.

[0055] For the hinge assembly detection tooling provided by the present application, after the first limiting surface 4 is abutted and positioned against the first hinge 6, the movable measuring member 3 can be slid in the direction close to the second hinge 7. As Figure 4 and Figure 5 shown, if the measuring portion 32 of the movable measuring member 3 can be inserted into the axial hole of the second hinge 7, the coaxiality between the first hinge 6 and the second hinge 7 is qualified. AsFigure 6 and Figure 7 As shown, if the measuring part 32 of the movable measuring piece 3 cannot be inserted into the shaft hole of the second hinge 7, the coaxiality between the first hinge 6 and the second hinge 7 is unqualified, which can effectively improve the detection accuracy of the coaxiality between the first hinge 6 and the second hinge 7.

[0056] Optionally, a tapered guiding surface is formed at the end of the measuring part 32 away from the positioning part 31 to facilitate the smooth insertion of the measuring part 32 into the shaft hole of the second hinge 7.

[0057] For the hinge assembly detection tooling provided by the present application, according to the designed dimension of the distance between the first hinge 6 and the second hinge 7, the movable measuring piece 3 and the measuring rod 1 are fixed. By making the first limiting surface 4 abut against the first hinge 6, the distance between the second limiting surface 5 and the second hinge 7 can be quickly read, or by making the second limiting surface 5 abut against the second hinge 7, the distance between the first limiting surface 4 and the first hinge 6 can be quickly read, so as to accurately obtain the difference between the actual distance and the designed dimension between the first hinge 6 and the second hinge 7, thereby judging whether the distance between the first hinge 6 and the second hinge 7 is qualified, which can effectively improve the detection accuracy and detection efficiency of the distance between the first hinge 6 and the second hinge 7.

[0058] Specifically, as Figure 8 and Figure 9 shown, make the first limiting surface 4 abut against the end face of the first hinge 6 on the side facing the limiting head 2, and read the distance H2 between the second limiting surface 5 and the end face of the second hinge 7 on the side facing the limiting head 2 through the scale of the measuring part 32. If the distance H2 is less than or equal to the preset value, the distance between the first hinge 6 and the second hinge 7 is qualified; if the distance H2 is greater than the preset value, the distance between the first hinge 6 and the second hinge 7 is unqualified; and / or, as Figure 10 and Figure 11 shown, make the second limiting surface 5 abut against the end face of the second hinge 7 on the side facing the limiting head 2, and read the distance H1 between the first limiting surface 4 and the end face of the first hinge 6 on the side facing the limiting head 2 through the scale of the measuring rod 1. If the distance H1 is less than or equal to the preset value, the distance between the first hinge 6 and the second hinge 7 is qualified; if the distance H1 is greater than the preset value, the distance between the first hinge 6 and the second hinge 7 is unqualified.

[0059] Optionally, along the axial direction of the measuring rod 1, the size of the limiting head 2 can be adjusted. By increasing the size of the limiting head 2 along the axial direction of the measuring rod 1, the limiting head 2 can be used for the staff to hold, so as to facilitate the taking and placing of the hinge assembly detection tooling provided by the present application.

[0060] Optionally, anti-slip patterns can be provided on the limit head 2 or an anti-slip sleeve can be sleeved thereon to increase the frictional force between the limit head 2 and the hand of the staff when the staff holds it.

[0061] As Figure 1 and Figure 2 shown, for the hinge assembly detection tooling provided by the present application, wherein, the measuring rod 1 includes a first section 11 and a second section 12 fixedly connected to each other. The first section 11 is connected to the limit head 2, and the second section 12 is connected to one end of the first section 11 away from the limit head 2. The movable measuring member 3 is slidably sleeved on the second section 12.

[0062] The first section 11, the second section 12 and the limit head 2 can be integrally formed to ensure the connection strength between the first section 11 and the second section 12 and between the first section 11 and the limit head 2, thereby ensuring the overall structural strength of the measuring rod 1 and the limit head 2.

[0063] As Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 10 shown, for the hinge assembly detection tooling provided by the present application, wherein, the diameter of the first section 11 is greater than the diameter of the second section 12, and the diameter of the first section 11 is equal to the outer diameter of the measuring portion 32. Since the aperture of the shaft hole of the first hinge 6 is equal to the space of the shaft hole of the second hinge 7, and the first section 11 is used to penetrate the shaft hole of the first hinge 6 and the measuring portion 32 is used to penetrate the shaft hole of the second hinge 7 during the detection process, making the diameter of the first section 11 equal to the outer diameter of the measuring portion 32 can make the gap difference between the diameter of the first section 11 and the aperture of the shaft hole of the first hinge 6 and the gap difference between the diameter of the measuring portion 32 and the aperture of the shaft hole of the second hinge 7 the same. In this way, the detection accuracy of the coaxiality between the first hinge 6 and the second hinge 7 can be further improved.

[0064] The difference between the diameter of the first section 11 and the aperture of the shaft hole of the first hinge 6 and the difference between the outer diameter of the measuring portion 32 and the aperture of the shaft hole of the second hinge 7 need to be less than the designed distance between the axis of the shaft hole of the first hinge 6 and the axis of the shaft hole of the second hinge 7. At this time, it can be ensured that when the first limiting surface 4 abuts against the first hinge 6 and the measuring portion 32 can be inserted into the second hinge 7, the coaxiality between the first hinge 6 and the second hinge 7 is qualified.

[0065] As Figures 3 to 11As shown, the hinge assembly detection tooling provided by the present application. Among them, an observation port 311 is provided on the positioning part 31. The observation port 311 penetrates through the inner surface and the outer surface of the positioning part 31 along the radial direction of the measuring rod 1, and the observation port 311 penetrates through the second limiting surface 5 along the axial direction of the measuring rod 1. By providing the observation port 311, when fixing the relative position between the movable measuring part 3 and the measuring rod 1, it is convenient for the staff to observe the relative position between the movable measuring part 3 and the limiting rod, so as to ensure that after fixing the movable measuring part 3 and the measuring rod 1, the distance between the first limiting surface 4 and the second limiting surface 5 is equal to the designed dimension.

[0066] For the hinge assembly detection tooling provided by the present application, the connection between the measuring rod 1 and the limiting head 2 is the 0 scale line of the scale on the measuring rod 1; so that in the state where the second limiting surface 5 abuts against the second hinge 7, it is convenient for the staff to quickly and accurately read the distance between the first limiting surface 4 and the first hinge 6.

[0067] The connection between the measuring part 32 and the positioning part 31 is the 0 scale line of the scale on the measuring part 32, so that in the state where the first limiting surface 4 abuts against the first hinge 6, it is convenient for the staff to quickly and accurately read the distance between the second limiting surface 5 and the second hinge 7.

[0068] As Figure 12 shown, for the hinge assembly detection tooling provided by the present application, the positioning part 33 is a bolt. A threaded hole is axially penetrated through the positioning part 31 along the measuring rod 1. The bolt is screwed into the threaded hole. The end of the bolt screwed into the interior of the positioning part 31 can abut against the measuring rod 1 for positioning. By adjusting the depth of the bolt screwed into the bolt hole, the abutting force between the bolt and the measuring rod 1 can be adjusted, so as to realize the reliable positioning between the movable measuring part 3 and the measuring rod 1.

[0069] The hinge assembly detection tooling provided by the present application measures whether the axes of the two hinges are on the same straight line through a simple structural form, solves the deviation existing in the non-concentricity of the two hinge axes and the out-of-tolerance of the spacing in the related art, meets the design problems in the installation of the two hinges, ensures the relevance between the car door and the car body, and further improves the overall accuracy of the vehicle.
