Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and in particular to a tooling for detecting the installation position of a car door handle. Background Technology

[0002] Door handle mounting holes are typically located on the outer window edge reinforcement plate of the door. After the outer window edge reinforcement plate is welded into the door assembly, the handle mounting holes are enclosed between the inner and outer door panels. The handle mounting holes can no longer be measured using a coordinate measuring machine with a double cantilever. When monitoring the dimensions of the conventional door assembly, only the gap between the mating surfaces of the outer door panels can be measured, and the dimensional deviation of the handle mounting holes cannot be directly detected and identified.

[0003] In existing technologies, a gauge is typically used to first measure the handle mounting holes on the inner door panel assembly. Then, the inner panel assembly is edge-wrapped. After all processes are completed and the entire door assembly is welded together, the outer panel mating surface is measured. The functional dimensions between the handle mounting holes and the outer panel mating surface are calculated using these two measurements. However, the two measurements accumulate errors, leading to decreased accuracy. Furthermore, since the inner panel assembly is a process component, the measurement results of the handle mounting holes taken at this stage will differ from the results of measurements taken after all processes are completed. This difference cannot be precisely controlled or quantified, resulting in distorted measurement results. Utility Model Content

Multiple positioning blocks are fixedly disposed on the handle profile, and the positioning blocks abut against the inner side of the outer door panel to position the relative position of the handle profile and the outer door panel in a first direction, a second direction, and a third direction. The clamping mechanism is fixedly disposed on the outer side of the handle profile, and the clamping mechanism abuts against the outer side of the outer door panel to cooperate with the positioning blocks in clamping the outer door panel. The detection limiting component is fixedly disposed on the inner side of the handle profile.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0022] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0023] In this application, "multiple" means two or more including two; similarly, "multiple groups" means two or more including two groups, and "multiple pieces" means two or more including two pieces.

[0024] It should be noted that the car door is divided into an inner panel assembly and an outer door panel. The handle is generally installed and fixed through the handle mounting holes on the inner panel assembly, while the outer door panel has a handle matching groove to facilitate the use of the handle.

[0025] During the production process, after the outer and inner door panels are welded and fixed, the handle mounting hole is enclosed between the inner panel assembly and the outer door panel. This makes it difficult to measure the relative positional relationship between the handle mounting hole and the handle matching groove. Measuring the size of the handle mounting hole in advance introduces a large error and cannot guarantee the accuracy of the measurement results after the welding process.

[0026] Based on this, this application proposes a door handle installation position detection fixture, which sets up a handle profile to simulate a handle, embeds the handle profile into the handle matching groove of the outer door panel, and adjusts the position of the handle profile in the handle matching groove by multiple positioning blocks to simulate the installation and use of a real handle. At the same time, the detection tool mounting hole on the detection limit component corresponds to the handle mounting hole on the inner panel assembly, and the detection tool is inserted into the handle mounting hole and the inspection tool mounting hole to detect the size data of the handle mounting hole and the relative position between the handle mounting hole and the handle matching groove.

[0027] The following description, with reference to the accompanying drawings, describes the door handle installation position detection fixture proposed in an embodiment of this application.

[0028] like Figure 1 and Figure 2 As shown, the door handle installation position detection fixture according to this embodiment includes a handle profile 1, a handle positioning component 2, and a detection limiting component 3; The handle positioning assembly 2 includes a positioning block 21 and a clamping mechanism 22. Multiple positioning blocks 21 are fixedly disposed on the handle profile 1. The positioning blocks 21 are used to abut against the inner side of the door outer panel 4 to position the relative position of the handle profile 1 and the door outer panel 4 in the first direction X, the second direction Y and the third direction Z. The clamping mechanism 22 is fixedly disposed on the outer side of the handle profile 1. The clamping mechanism 22 is used to abut against the outer side of the door outer panel 4 to cooperate with the positioning blocks 21 to clamp the door outer panel 4. The detection limiting component 3 is fixedly installed on the inner side of the handle profile 1. The detection limiting component 3 is provided with a detection tool mounting hole 31 corresponding to the handle mounting hole 6, so as to detect the relative position of the handle matching groove 41 and the handle mounting hole 6. Among them, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0029] Specifically, in this embodiment, multiple positioning blocks 21 abut against the inner side of the outer door panel 4 and the inner sidewall of the handle matching groove 41, respectively, thereby adjusting and determining the relative position of the handle profile 1 and the handle matching groove 41 on the outer door panel 4. However, at this time, the position of the handle profile 1 is not fixed. During subsequent testing, the handle profile 1 is prone to positional deviation due to external vibrations and shaking, or even falls out of the handle matching groove 41, which will cause trouble for subsequent testing. In this embodiment, an additional clamping mechanism 22 is provided, which is fixedly set on the outside of the handle profile 1, so that the clamping structure can abut against the outer side of the outer door panel 4, thereby cooperating with the positioning block 21 abutting against the inner side of the outer door panel 4 to clamp the outer door panel 4, thereby fixing the relative position of the handle profile 1 and the outer door panel 4, avoiding the position of the handle profile structure from being edited, and thus ensuring the accuracy and stability of subsequent testing results.

[0030] In some embodiments of this application, the handle positioning component 2 includes a first positioning block 211, a second positioning block 212, and a third positioning block 213; The first positioning block 211 extends along the first direction X and abuts against the inner wall of the handle matching groove 41; The second positioning block 212 extends along the second direction Y and abuts against the inner wall of the outer panel 4 of the door. The third positioning block 213 extends along the third direction Z and abuts against the inner wall of the handle matching groove 41.

[0031] Furthermore, a first positioning block 211 is provided on one side of the handle profile 1 in the first direction X; The handle profile 1 is provided with multiple clamping mechanisms 22 at intervals along the first direction X, and multiple second positioning blocks 212 are fixedly disposed on the side of the handle profile 1 away from the clamping mechanisms 22. The handle-shaped part 1 has multiple mounting slots 11 on the side facing the second direction Y and on the side facing the third direction. A third positioning block 213 is fixedly installed in the mounting slot 11.

[0032] See Figure 1 and Figure 2Specifically, in this embodiment, the positioning block 21 is divided into three parts, which are used to position the handle contouring component in different directions. The first positioning block 211 is embedded in the side of the handle contouring component 1 facing the first direction X, and the first positioning block 211 also extends along the first direction X. The end of the first positioning block 211 away from the handle contouring component 1 abuts against the inner wall of the handle matching groove 41. The relative position of the handle contouring component 1 and the outer door panel 4 in the first direction X can be adjusted by adjusting the size and position of the first positioning block 211. The second positioning block 212 is... Multiple second positioning blocks 212 are fixedly installed on the side of the handle contour piece 1 facing the inner panel assembly. Each second positioning block 212 is an L-shaped structure, with its end abutting against the inner sidewall of the outer door panel 4, thereby realizing the positioning confirmation of the handle contour piece 1 in the second direction Y. The second positioning block 212 is also arranged facing the clamping mechanism 22, so as to cooperate with the clamping mechanism 22 to fix the position of the handle contour piece 1. Finally, the third positioning block 213 is set on the top of the handle contour piece 1 through the mounting groove 11 and abuts against the handle matching groove 41, thereby positioning the handle contour piece 1 in the third direction Z.

[0033] Furthermore, it should be noted that the first positioning block 211, the second positioning block 212, and the third positioning block 213 are all fixedly connected to the handle profile 1 by bolts or rivets. The size and position of the positioning block 21 can be adjusted by adding shims or by directly replacing it with a positioning block 21 of a different size. In one specific embodiment, one first positioning block 211 is provided, six second positioning blocks 212 are provided, and two third positioning blocks 213 are arranged side-by-side along the first direction.

[0034] In some embodiments of this application, the first positioning block 211, the second positioning block 212 and the third positioning block 213 are all provided with positioning protrusions 214 at the end facing the outer door panel 4, and the positioning protrusions 214 are used to abut against the outer door panel 4.

[0035] Specifically, the positioning protrusion 214 reduces the contact area between the positioning block 21 and the outer door panel 4, improving the stability of the contact state and the stability of the handle profile 1 position.

[0036] In some embodiments of this application, the clamping mechanism 22 includes a claw 221 and an adjusting bolt 222. The adjusting bolt 222 is threadedly connected to the handle profile 1 and connected to the claw 221. The adjusting bolt 222 is used to drive the claw 221 to move toward the outer panel 4 of the door to abut against the outer side of the outer panel 4.

[0037] Specifically, after the position of the handle profile 1 is determined by the positioning block 21, the adjusting bolt 222 is rotated to drive the claw 221 to move towards the outer door panel 4, thereby abutting against the outer side of the outer door panel 4. In conjunction with the positioning block 21 abutting against the inner side of the outer door panel 4, the outer door panel 4 is clamped, making the position of the handle profile 1 more stable and reliable.

[0038] Of course, in some other alternative embodiments, the spring-driven claw 221 can also be used to move toward the outer door panel 4 to clamp the outer door panel 4.

[0039] In some embodiments of this application, the claw 221 includes a mounting plate 2211, which is connected to an adjusting bolt 222. The mounting plate 2211 has abutment blocks 2212 at both ends along the third direction Z, and the abutment blocks 2212 are used to abut against the outer panel 4 of the door.

[0040] See Figure 1 Specifically, the end of the abutment block 2212 can be made larger to increase the surface area, or a material with a rougher surface and greater friction can be used to more stably clamp the outer door panel 4, thereby improving the stability and reliability of the position of the handle profile 1.

[0041] In some embodiments of this application, the abutment block 2212 and the second positioning block 212 are disposed opposite each other in the second direction Y.

[0042] Specifically, the abutment block 2212 and part of the second positioning block 212 are arranged opposite to each other in the second direction to avoid problems such as bending or denting of the outer door panel 4 due to uneven force during the clamping process, thus ensuring the integrity and aesthetics of the appearance of the outer door panel 4.

[0043] In some embodiments of this application, the detection limiting component 3 includes a first connecting arm 32 and a second connecting arm 33. The first connecting arm 32 extends along the third direction Z and is fixedly connected to the handle profile 1. One end of the first connecting arm 32 is provided with a detection tool mounting hole 31, and the other end of the first connecting arm 32 is fixedly connected to the second connecting arm 33. The second connecting arm 33 is L-shaped, and each end of the second connecting arm 33 is provided with a detection tool mounting hole 31.

[0044] Specifically, the dimensions and shapes of the first connecting arm 32 and the second connecting arm 33 are designed according to the position of the handle mounting hole 6 on the inner panel assembly. The first connecting arm 32 and the second connecting arm 33 are used to align the detection tool mounting hole 31 at their ends with the handle mounting hole 6 on the inner panel assembly. In a specific embodiment, the first connecting arm 32, the second connecting arm 33, and the handle profile 1 are all made of aluminum, thereby reducing the overall weight of the tooling.

[0045] In some embodiments of this application, a sleeve 34 for cooperating with the testing tool is provided in the testing tool mounting hole 31. The sleeve 34 can provide guidance for the testing tool 5 and prevent wear and damage to the testing tool mounting hole 31 caused by frequent use of the testing tool 5.
