Description

Technical Field

[0001] This invention relates to the field of automotive door installation process inspection, specifically to an inspection tool module and inspection method for installing automotive door assemblies. Background Technology

[0002] As people's demands for vehicle appearance and performance increase, concealed door handles, which are both aesthetically pleasing and reduce wind noise, are increasingly being adopted in new car models. Unlike traditional exposed handles, concealed door handles are directly mounted on the outer panel of the door assembly, protruding from it. This structure only requires controlling the stamping precision of the outer panel, making it simple and easy to control. Concealed door handle assemblies are typically installed on an inner mounting plate within the door assembly. The handle matches the perforated surface of the outer panel, forming a seamless integration, which is both aesthetically pleasing and reduces wind noise. However, the concealed door handle itself has a complex structure, and the different installation methods also complicate the overall door assembly structure. First, the inner door panel and internal door components are welded together to form the inner door panel welding assembly. Then, the concealed outward-opening door handle assembly mounting plate and the inner door panel welding assembly are welded together to form the inner door panel welding assembly. Finally, the inner door panel welding assembly is fastened to the outer door panel to form the door assembly. The concealed outward-opening handle installation structure is complex, involving numerous installation steps and a long precision control chain. Furthermore, the installation precision of the concealed outward-opening handle directly affects the appearance and functionality of the concealed outward-opening handle assembly, thus placing higher demands on the precision testing and control of the door assembly manufacturing process.

[0003] Existing technologies include inspection fixtures for door assemblies and individual inspection fixtures for concealed outward-opening handle assemblies. However, the door assembly inspection fixture can only inspect the accuracy of the matching hole surface between the handle hole of the outer door panel and the handle of the concealed outward-opening handle assembly; it cannot inspect or track the matching accuracy of the welding contact surface between the concealed outward-opening handle assembly mounting plate and the welded components of the inner door panel, nor the accuracy of the concealed outward-opening handle assembly mounting plate within the welded inner door panel assembly. The individual inspection fixture for the concealed outward-opening handle assembly mounting plate is generally placed at the original equipment manufacturer (OEM), which cannot provide or inspect data on the tolerance deviation direction of the contact surface between the concealed outward-opening handle assembly mounting plate and the welded components of the inner door panel in a timely manner. Furthermore, creating an additional individual inspection fixture for the concealed outward-opening handle assembly mounting plate would increase costs and require more storage space. In the OEM welding workshop, it's impossible to determine the matching precision of the incoming material of the concealed outward-opening handle assembly mounting plate and the door inner panel. Therefore, it's impossible to accurately provide rectification instructions regarding the tolerance orientation of the contact surfaces between the matching concealed outward-opening handle assembly mounting plate and the door inner panel welding components. Furthermore, it's impossible to inspect the precision of the concealed outward-opening handle assembly mounting plate within the welded door inner panel assembly, thus making it impossible to guarantee whether the overall precision of the door assembly meets the installation requirements of the concealed outward-opening handle. Summary of the Invention

[0004] One objective of this invention is to provide a fixture module for installing a car door assembly, thereby solving the problem that the existing fixtures have limited detection functions and cannot simultaneously detect the fit between the contact surface of the hidden outward-opening handle assembly mounting plate and the welding assembly of the inner door panel during the installation process, the surface accuracy and hole accuracy of the handle mounting position of the hidden outward-opening handle assembly mounting plate in the inner door panel welding assembly, and the surface matching accuracy of the handle hole in the car door assembly. Another objective of this invention is to provide a detection method.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A tooling module for installing a car door assembly includes a mounting base. The mounting base is provided with multiple door inner panel positioning pins and multiple door inner panel fixing mechanisms. The door inner panel fixing mechanisms are used to fix the door inner panel on the mounting base. The mounting base is provided with a first mounting base and a second mounting base. The first mounting base and the second mounting base can be interchangeably mounted with a clamping and positioning mechanism for detecting the fit between the contact surface of the mounting plate of the concealed outward-opening handle assembly and the welding assembly of the door inner panel, a first detection mechanism for detecting the surface accuracy and hole accuracy of the installation position of the concealed outward-opening handle assembly in the welding assembly of the door inner panel, or a second detection mechanism for detecting the matching accuracy of the handle hole surface in the door assembly.

[0007] According to the above technical means, a door inner panel fixing mechanism is set on the mounting base. By fixing the door inner panel, the door inner panel welding components, the door inner panel assembly, and the door assembly can be fixed. This ensures that the present invention can perform phased inspections during the installation of the door assembly. By setting a first mounting base and a second mounting base on the mounting base, the number of modules on the mounting base is reduced while ensuring the inspection during the installation of the door assembly, thus saving costs.

[0008] Furthermore, the door inner panel fixing mechanism includes a door inner panel positioning reference block, an inner panel clamping module paired with the door inner panel positioning reference block, and a clamping operating rod. The clamping operating rod is connected to the inner panel clamping module so that by moving the clamping operating rod, the door inner panel positioning reference block and the inner panel clamping module are respectively clamped on the opposite positioning reference surfaces of the door inner panel.

[0009] Based on the above technical means, the inner panel of the car door is fixed by the cooperation of the positioning reference block of the inner panel, the inner panel clamping module and the clamping operating rod, so as to avoid the movement of the inner panel of the car door causing the test results to be distorted.

[0010] Furthermore, the clamping and positioning mechanism, the first detection mechanism, and the second detection mechanism are all provided with mounting arms for connecting to the first mounting base and / or the second mounting base.

[0011] Based on the above technical means, the design of some parts of the clamping and positioning mechanism, the first detection mechanism, and the second detection mechanism has been simplified, which facilitates production and manufacturing.

[0012] Furthermore, the mounting arm is an L-shaped plate structure, with multiple positioning grooves and multiple mounting holes at one end. The mounting arm is positioned on the first mounting base and / or the second mounting base by cooperating with the positioning pin through the positioning grooves. The mounting arm is fastened to the first mounting base and / or the second mounting base by cooperating with the large-head locking bolt through the mounting holes.

[0013] According to the above technical means, the positioning pin and groove cooperate to facilitate the placement of the mounting arm on the first mounting base and / or the second mounting base, and the bolt connection facilitates the disassembly of the mounting arm.

[0014] Furthermore, the clamping and positioning mechanism also includes a positioning component, multiple positioning reference blocks, and multiple clamping components. The positioning component and the positioning reference blocks are connected to the end of the mounting arm away from the first mounting base, and the positioning reference blocks are provided with clamping components.

[0015] Based on the above technical means, the positioning component is used to position the hidden outward-opening handle assembly mounting plate, and the positioning reference block and clamping component are used to clamp the hidden outward-opening handle assembly mounting plate to simulate the positional relationship between the door inner panel welding component and the hidden outward-opening handle assembly mounting plate before welding, thereby realizing the detection of the contact surface between the door inner panel welding component and the hidden outward-opening handle assembly mounting plate.

[0016] Furthermore, the clamping assembly includes a clamping block, a locking screw, and a wing-shaped locking nut. The clamping block is an open square ring, one end of which abuts against the positioning reference block. The other end of the clamping block has a threaded hole on its side wall. The locking screw passes through the threaded hole and connects to the wing-shaped locking nut, so as to clamp the concealed outward-opening handle assembly mounting plate by adjusting the distance between the positioning reference block and the end of the locking screw by twisting the wing-shaped locking nut.

[0017] Based on the above technical means, the mounting plate of the concealed outward-opening handle assembly is clamped by the cooperation of the screw and nut. The operation is simple and effective. The fit of the contact surface is detected by the gap gauge. The operation is simple and can intuitively reflect the test results.

[0018] Furthermore, the positioning assembly includes a spring, a positioning pin, a positioning pin operating rod, and a sleeve. The sleeve has an L-shaped groove on its side wall, the positioning pin operating rod is mounted on the side wall of the positioning pin, the sleeve is fitted onto the positioning pin, and the sleeve and the positioning pin are abutted by the spring.

[0019] According to the above technical means, since the positioning component has a retractable structure, it is easy for the positioning pin to be smoothly inserted into or pulled out of the positioning hole of the hidden outward-opening handle assembly mounting plate.

[0020] Furthermore, the first detection mechanism includes a detection base and a connecting structure. The connecting structure is connected to the end of the mounting arm away from the first mounting base. The detection base is connected to the connecting structure. The detection base is provided with multiple detection structures. The detection structure includes a hole detection pin hole and multiple surface detection pin holes arranged in a circumferential array around the hole detection pin hole. The connecting structure enables the detection base to be in a predetermined position.

[0021] Based on the aforementioned technical means, the positional relationship of the detection base is altered by the connecting structure, enabling the detection base to detect the accuracy of the mounting holes and mounting surfaces of the concealed outward-opening handle assembly mounting plate. Detection is performed by checking the pin holes through both hole and surface inspections, making the operation simple and providing a direct visual representation of the detection results.

[0022] Furthermore, the second detection mechanism includes a handle detection block for detecting the handle installation accuracy and a connector, wherein the connector is connected to the end of the mounting arm away from the first mounting base, and the handle detection block is connected to the connector.

[0023] According to the above technical means, the position of the handle detection block is changed by the connector so that the handle detection block can be inserted into the handle hole surface. Since the shape, size and thickness of the handle detection block are consistent with the hidden outward-opening handle pre-installed on the door assembly, the matching accuracy of the handle hole surface can be detected by feeler gauge and height difference meter, which facilitates subsequent rectification.

[0024] A method for testing the installation of a vehicle door assembly includes the following staged tests:

[0025] First testing phase: Use a clamping and positioning mechanism to position the hidden outward-opening handle assembly mounting plate and the door inner panel welding assembly. If the hidden outward-opening handle assembly mounting plate and the door inner panel welding assembly are not welded together, test the contact surface fit of the hidden outward-opening handle assembly mounting plate and the door inner panel welding assembly.

[0026] Second testing stage: Replace the first testing mechanism. When the hidden outward-opening handle assembly mounting plate is welded to the door inner panel welding assembly to form the door inner panel welding assembly, use the first testing mechanism to test the surface accuracy and hole accuracy of the handle mounting position of the hidden outward-opening handle assembly mounting plate.

[0027] Third testing stage: Replace with a second testing mechanism. When the inner door panel welding assembly and the outer door panel are fastened together to form a door assembly, the second testing mechanism tests the matching accuracy of the handle hole surface on the door assembly.

[0028] Based on the aforementioned technical means, through phased testing, errors in the door installation process can be corrected in a timely manner, thereby ensuring the installation effect of the door assembly.

[0029] Furthermore, the first detection stage includes the following steps:

[0030] The door inner panel welding assembly is fixed on the door inner panel positioning reference block;

[0031] The clamping and positioning mechanisms are respectively installed on the first mounting base and the second mounting base;

[0032] The concealed outward-opening handle assembly mounting plate is placed on the inner panel of the door, and the concealed outward-opening handle assembly mounting plate is clamped by the clamping and positioning mechanism.

[0033] Use a gap gauge to check the fit between the welding assembly of the inner door panel and the mounting plate of the concealed outward-opening handle assembly.

[0034] Based on the above technical means, the fit between the welding components of the inner door panel and the mounting plate of the concealed outward-opening handle assembly can be detected in a timely manner, ensuring the efficiency of the inspection.

[0035] Furthermore, the second detection stage includes the following steps:

[0036] The inner door panel welding assembly is fixed on the inner door panel positioning reference block;

[0037] Install the first testing mechanism on the first mounting base;

[0038] A hole detection pin is inserted into the hole detection pin hole to determine the hole accuracy of the mounting position of the concealed outward-opening handle assembly; a surface detection pin is inserted into the surface detection pin hole, and the surface accuracy of the mounting position of the concealed outward-opening handle assembly is determined by measuring the gap value between the surface detection pin and the detection base.

[0039] Based on the above technical means, the hole accuracy and surface accuracy of the mounting position of the concealed outward-opening handle assembly can be detected in a timely and intuitive manner.

[0040] Furthermore, the third detection stage includes the following steps:

[0041] The door assembly is fixed on the positioning reference block of the inner door panel;

[0042] Install the second detection mechanism on the first mounting base;

[0043] Use a gap gauge to measure the gap between the handle detection block and the handle hole surface; use a height difference meter to measure the height difference between the handle detection block and the handle hole surface.

[0044] Based on the above technical means, the matching condition of the handle hole surface can be directly detected by the gap gauge, and the height difference meter can detect the unevenness between the handle hole surface and the handle detection block, which facilitates subsequent rectification.

[0045] The beneficial effects of this invention are:

[0046] (1) The present invention sets up a first mounting base and a second mounting base, which cooperate with the clamping and fixing structure, the first detection mechanism and the second detection mechanism to detect several stages in the process of installing the door assembly, thereby ensuring the overall accuracy of the door assembly and meeting the installation requirements of the hidden outward opening handle.

[0047] (2) This invention uses a gap gauge, a hole detection pin hole, a surface detection pin hole, a height difference meter, a clamping and fixing structure, a first detection mechanism, and a second detection mechanism to detect several stages in the installation process of the car door assembly. This allows for quick and timely detection results and determination of accuracy, which in turn facilitates subsequent rectification. Attached Figure Description

[0061] See Figure 1-3This invention provides a tooling module for installing a car door assembly, including a mounting base 100. The mounting base 100 is provided with a plurality of car door inner panel positioning pins 200 and a plurality of car door inner panel fixing mechanisms. The car door inner panel fixing mechanisms are used to fix the car door inner panels on the mounting base 100. The mounting base 100 is provided with a first mounting base 500 and a second mounting base 501. Both the first mounting base 500 and the second mounting base 501 can be interchangeably mounted with a clamping and positioning mechanism 600 for detecting the fit of the contact surface between the hidden outward-opening handle assembly mounting plate 221 and the car door inner panel welding assembly 222, a first detection mechanism 800 for detecting the surface accuracy and hole accuracy of the installation position of the hidden outward-opening handle assembly 1 in the car door inner panel welding assembly 22, or a second detection mechanism 900 for detecting the matching accuracy of the handle hole surface 211 in the car door assembly 2. It should be noted that the inner door panel and the parts inside the door are welded together to form the inner door panel welding assembly 222. The hidden outward-opening handle assembly mounting plate 221 and the inner door panel welding assembly 222 are welded together to form the inner door panel welding assembly 22. The inner door panel welding assembly 22 is then fastened to the outer door panel 21 to form the door assembly 2. It should be further noted that the inspection fixture module for installing the door assembly of the present invention has a vertical structure. The first mounting base 500 is closer to the hidden outward-opening handle assembly 1 than the second mounting base 501. During inspection, the inner door panel positioning pin 200 is inserted into the matching hole in the inner door panel to achieve the positioning of the inner door panel. The hidden outward-opening handle assembly mounting plate 221 can only be clamped and fixed when both the first mounting base 500 and the second mounting base 501 are equipped with clamping and positioning mechanisms 600. When inspecting the surface accuracy and hole accuracy of the mounting position of the concealed outward-opening handle assembly 1 in the inner door panel welding assembly 22, a first inspection mechanism 800 is installed on the first mounting base 500, but the first inspection mechanism 800 does not need to be installed on the second mounting base 501; when inspecting the matching accuracy of the handle hole surface 211 in the door assembly 2, a second inspection mechanism 900 is installed on the first mounting base 500, but the second inspection mechanism 900 does not need to be installed on the second mounting base 501.

[0062] Specifically, the door inner panel fixing mechanism includes a door inner panel positioning reference block 300, an inner panel clamping module 400 paired with the door inner panel positioning reference block 300, and a clamping operation rod 410. The clamping operation rod 410 is connected to the inner panel clamping module 400 so that by moving the clamping operation rod 410, the door inner panel positioning reference block 300 and the inner panel clamping module 400 are respectively clamped on the corresponding positioning reference surfaces of the door inner panel. It should be noted that the inner door panel has a plate-like structure. The surface formed by the contact between multiple inner door panel positioning reference blocks 300 and one side of the inner door panel is the reference surface of the inner door panel. The inner panel clamping module 400 contacts the other side of the inner door panel. The clamping operating lever 410 has one end connected to the mounting base 100 and the other end connected to the inner panel clamping module 400. By moving the clamping operating lever 410, the inner panel clamping module 400 abuts against the inner door panel to fix the inner door panel. For example, the inner panel clamping module 400 includes a pull rod connected to the clamping operating lever 410, and a rod-shaped clamping block is hinged to the end of the pull rod away from the clamping operating lever 410. 6041, by moving the clamping operation lever 410, the aforementioned pull rod moves along the direction of the pull rod body. The pull rod causes the aforementioned rod-shaped clamping block 6041 to rotate. Before the first stage of testing, the clamping operation lever 410 is pushed to open the inner panel clamping module 400 (i.e., the rod-shaped clamping block 6041 rotates away from the mounting base 100). Then, the inner panel of the car door is placed on the inner panel positioning reference block 300. The clamping operation lever 410 is then moved again to make the rod-shaped clamping block 6041 rotate towards the mounting base 100, pressing against the inner panel of the car door to achieve clamping. The clamping operation lever 410 is fixed after being moved by the fastener connected to the mounting base 100.

[0063] In addition, the clamping and positioning mechanism 600, the first detection mechanism 800, and the second detection mechanism 900 are all provided with mounting arms 601 for connecting to the first mounting base 500 and / or the second mounting base 501. By providing mounting arms 601, it is convenient to install the clamping and positioning mechanism 600, the first detection mechanism 800, and the second detection mechanism 900 on the first mounting base 500 and / or the second mounting base 501.

[0064] Specifically, see Figure 4 The mounting arm 601 has an L-shaped plate structure. One end of the mounting arm 601 has multiple positioning grooves and multiple mounting holes. The mounting arm 601 is positioned on the first mounting base 500 and / or the second mounting base 501 by engaging with the positioning pin 510 through the positioning grooves. The mounting arm 601 is fastened to the first mounting base 500 and / or the second mounting base 501 by engaging with the large-head locking bolt 520 through the mounting holes. The positioning grooves on the mounting arm 601 enable quick positioning, and the large-head locking bolt 520 makes the installation and disassembly of the mounting arm 601 easier.

[0065] In addition, the clamping and positioning mechanism 600 also includes a positioning component, multiple positioning reference blocks 603, and multiple clamping components 604. The positioning component and the positioning reference blocks 603 are connected to the end of the mounting arm 601 away from the first mounting base 500, and the clamping components 604 are provided on the positioning reference blocks 603. The positioning component can determine the fixed position of the concealed outward-opening handle assembly mounting plate 221, and the clamping components 604 realize the fixation of the concealed outward-opening handle assembly mounting plate 221.

[0066] Specifically, the clamping assembly 604 includes a clamping block 6041, a locking screw 610, and a wing-shaped locking nut 620. The clamping block 6041 is an open square ring. One end of the clamping block 6041 abuts against the positioning reference block 603. The other end of the clamping block 6041 has a threaded hole on its side wall. The locking screw 610 passes through the threaded hole and connects to the wing-shaped locking nut 620. The distance between the positioning reference block 603 and the end of the locking screw 610 is adjusted by twisting the wing-shaped locking nut 620 to clamp the concealed outward-opening handle assembly mounting plate 221. The concealed outward-opening handle assembly mounting plate 221 has a panel for clamping the positioning reference block 603. When the concealed outward-opening handle assembly mounting plate 221 is positioned, the positioning reference block 603 is in contact with one side of the aforementioned panel, and the clamping block 6041 is in contact with the other side of the aforementioned panel. The concealed outward-opening handle assembly mounting plate 221 is fixed by twisting the butterfly locking nut 620.

[0067] Specifically, the positioning assembly includes a spring, a positioning pin 602, a positioning pin operating rod 6021, and a sleeve. The sleeve has an L-shaped groove on its side wall. The positioning pin operating rod 6021 is mounted on the side wall of the positioning pin 602. The sleeve is fitted onto the positioning pin 602, and the sleeve and positioning pin 602 are abutted by the spring. It should be noted that the positioning pin operating rod 6021 moves along the L-shaped groove, thereby moving the positioning pin 602 and achieving the extension and retraction of the positioning pin 602. The spring ensures that the positioning pin 602 cannot move freely after being inserted into the concealed outward-opening handle assembly mounting plate 221. Furthermore, the concealed outward-opening handle assembly mounting plate 221 has holes corresponding to the positioning pin 602.

[0068] In addition, see Figure 5-6The first inspection mechanism 800 includes an inspection base 820 and a connecting structure 810. The connecting structure 810 is connected to the end of the mounting arm 601 away from the first mounting base 500. The inspection base 820 is connected to the connecting structure 810. The inspection base 820 is provided with multiple inspection structures, including a hole inspection pin hole 8201 and multiple surface inspection pin holes 8202 arranged in a circumferential array around the hole inspection pin hole 8201. The connecting structure 810 enables the inspection base 820 to be in a predetermined position. It should be noted that since the first inspection mechanism 800 inspects the surface accuracy and hole accuracy of the installation position of the concealed outward-opening handle assembly 1 in the inner door panel welding assembly 22, the connecting structure 810 is provided between the mounting arm 601 and the inspection base 820 to ensure that the inspection base 820 is in the installation position of the concealed outward-opening handle assembly 1, thereby performing the inspection. In addition, the mounting position of the concealed outward-opening handle assembly 1 has mounting holes and mounting surfaces that match the aforementioned detection structure, and the first detection mechanism 800 detects the aforementioned mounting holes and mounting surfaces.

[0069] Specifically, see Figure 7-8 The second testing mechanism 900 includes a handle testing block 902 and a connector 901 for testing the handle installation accuracy. The connector 901 is connected to the end of the mounting arm 601 away from the first mounting base 500, and the handle testing block 902 is connected to the connector 901. It should be noted that the shape and size of the handle testing block 902 are exactly the same as the concealed outward-opening handle assembly handle 11. The handle testing block 902 replaces the concealed outward-opening handle assembly handle 11 to test the matching with the handle hole surface 211. In addition, the mounting arm 601 makes the handle testing block 902 fit against the handle hole surface 211. During testing, the handle testing block 902 is inserted into the handle hole surface 211 for testing.

[0070] The present invention also provides a method for testing the installation of a door assembly, including the following staged tests:

[0071] First testing stage: Use clamping and positioning mechanism 600 to position the hidden outward opening handle assembly mounting plate 221 and the door inner panel welding assembly 222. When the hidden outward opening handle assembly mounting plate 221 and the door inner panel welding assembly 222 are not welded together, test the contact surface fit of the hidden outward opening handle assembly mounting plate 221 and the door inner panel welding assembly 222.

[0072] Second testing stage: Replace the first testing mechanism 800. With the hidden outward-opening handle assembly mounting plate 221 and the door inner panel welding assembly 222 welded together to form the door inner panel welding assembly 22, use the first testing mechanism 800 to test the surface accuracy and hole accuracy of the handle mounting position of the hidden outward-opening handle assembly mounting plate 221.

[0073] Third inspection stage: Replace the second inspection mechanism 900. With the inner door panel welding assembly 22 and the outer door panel 21 fastened together to form the door assembly 2, the second inspection mechanism 900 inspects the matching accuracy of the handle hole surface 211 on the door assembly 2.

[0074] It should be noted that by conducting phased inspections, we can understand the installation status at different stages of the car door installation process. This allows us to promptly rectify any significant errors that may accumulate and prevent the concealed outward-opening handle from not perfectly fitting the handle hole surface 211.

[0075] Specifically, the first testing phase includes the following steps:

[0076] Fix the inner door panel welding assembly 222 onto the inner door panel positioning reference block 300;

[0077] The clamping and positioning mechanism 600 is installed on the first mounting base 500 and the second mounting base 501 respectively;

[0078] The concealed outward-opening handle assembly mounting plate 221 is placed on the inner panel of the door, and the concealed outward-opening handle assembly mounting plate 221 is clamped by the clamping and positioning mechanism 600.

[0079] Use a gap gauge to check the fit between the contact surfaces of the door inner panel welding assembly 222 and the concealed outward-opening handle assembly mounting plate 221.

[0080] It should be noted that the inner panel clamping module 400 should be fully opened first, and then the inner panel welding assembly 222 should be placed on the inner panel positioning reference block 300. The inner panel welding assembly 222 is positioned by the inner panel positioning pin 200 and fixed by the clamping positioning mechanism 600. The gap gauge can quickly detect the gap between the inner panel welding assembly 222 and the hidden outward opening handle assembly mounting plate 221, so as to intuitively understand the fit. If the fit is not good, it can be rectified in time to avoid affecting the subsequent installation due to poor fit.

[0081] Specifically, the second testing phase includes the following steps:

[0082] Fix the inner door panel welding assembly 22 onto the inner door panel positioning reference block 300;

[0083] The first testing unit 800 is installed on the first mounting base 500;

[0084] Hole detection pin 8203 is inserted into hole detection pin hole 8201 to determine the hole accuracy of the mounting position of concealed outward-opening handle assembly 1; face detection pin 8204 is inserted into face detection pin hole 8202, and the face accuracy of the mounting position of concealed outward-opening handle assembly 1 is determined by measuring the gap value between face detection pin 8204 and detection base 820.

[0085] It should be noted that when the hole detection pin 8203 is inserted into the hole detection pin hole 8201, if the insertion process is smooth, the hole accuracy at the mounting position of the concealed outward-opening handle assembly 1 is judged to be qualified; when the face detection pin 8204 is inserted into the face detection pin hole 8202, the pin part of the face detection pin 8204 enters the face detection pin hole 8202, and the part of the face detection pin 8204 outside the face detection pin hole 8202 used for face accuracy detection forms a gap with the detection base 820. The face accuracy at the mounting position of the concealed outward-opening handle assembly 1 is determined by measuring the gap between the face detection pin 8204 and the detection base 820 with a gap gauge.

[0086] Specifically, the third testing phase includes the following steps:

[0087] Fix the door assembly 2 onto the door inner panel positioning reference block 300;

[0088] The second testing unit 900 is installed on the first mounting base 500;

[0089] Use a gap gauge to measure the gap between the handle detection block 902 and the handle hole surface 211; use a height difference meter to measure the height difference between the handle detection block 902 and the handle hole surface 211.

[0090] It should be noted that the handle detection block 902 is inserted into the handle hole surface 211. The gap between the handle detection block 902 and the handle hole surface 211 can be directly detected by a gap gauge. The height difference meter can detect the unevenness of the handle detection block 902 in the handle hole surface 211, which facilitates subsequent rectification.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
