[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] The following is for reference. Figures 1-8 A production system according to an embodiment of the present utility model is described.

[0035] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the production system according to an embodiment of the present invention includes: a control unit, an assembly robot, and a testing fixture 100.

[0036] Specifically, the assembly robot is electrically connected to the control unit. The assembly robot is used to assemble car doors on the car body. The car door is suitable for installing car door components. The car body has a body mating part, and the car door components have a component mating part. The component mating part is used to mate with the body mating part. The inspection fixture 100 includes: a fixture bracket 10, a contouring part 20, and an inspection piece 30. The contouring part 20 is disposed on the fixture bracket 10 and has a contouring part 21. The contour of the contouring part 21 is adapted to the contour of the component mating part. The inspection piece 30 is disposed on the contouring part 21 and is electrically connected to the control unit. The inspection fixture 100 is suitable for being placed on the car door so that the contouring part 21 mates with the body mating part to simulate the state of the component mating part mates with the body mating part. The inspection piece 30 is suitable for detecting the distance between the contouring part 21 and the body mating part.

[0037] The door can be a side door or a rear door. Understandably, after the door is assembled onto the vehicle body, the relative posture of the door and the body will affect the relative posture of the door components on the door and the body.

[0038] During the vehicle production process, after the vehicle body moves to the working area of ​​the assembly robot, the assembly robot assembles the door onto the vehicle body. Then, the operator places the inspection fixture 100 at the designated position on the door and makes the contouring part 21 cooperate with the body mating part. The position of the contouring part 21 on the door is consistent with the position of the component mating part on the door. The contouring part 21 simulates the actual mating state of the door component after it is assembled onto the door and cooperates with the body mating part.

[0039] Then, the operator observes the relative posture of the contouring part 21 and the body mating part, and quickly judges whether the relative posture of the door component and the body mating part meets the requirements. At the same time, the detection part 30 detects the distance between the contouring part 21 and the body mating part and transmits the detection data to the control unit. On the one hand, it can accurately judge whether the relative posture of the door component and the body mating part meets the requirements. On the other hand, the control unit can adjust the assembly parameters of the assembly robot according to the detection data, so that the assembly robot can adjust the assembly position of the door on the body. Thus, it can quickly detect whether the positional accuracy of the door on the body meets the assembly requirements, and can automatically adjust the assembly parameters of the assembly robot.

[0040] According to the production system of this utility model embodiment, after the car door is assembled onto the car body, the inspection fixture 100 is placed on the car door. By inspecting the matching between the contour part 21 and the body body mating part, the assembly accuracy of the car door on the body body can be inspected to see if it meets the requirements. The operation is relatively convenient, thereby improving the inspection efficiency. Furthermore, the assembly parameters of the car door can be automatically adjusted based on the measurement results of the inspection piece 30. Thus, the production efficiency of the vehicle can be improved, and the assembly accuracy of the car door on the body can be improved.

[0041] In some embodiments of this utility model, such as Figure 2 , Figure 3 and Figure 6As shown, the door component includes a spoiler, the component mating part includes a first mating part on the spoiler, the body mating part includes a second mating part, the first mating part is used to mate with the second mating part, the contouring part 20 includes a first contouring part 22, the contouring part 21 includes a first contouring part 221 on the first contouring part 22, the contour of the first contouring part 221 is adapted to the contour of the first mating part, the first contouring part 221 is provided with a first detection element 31, the detection fixture 100 is adapted to be placed on the door so that the first contouring part 221 mates with the second mating part to simulate the state of the first mating part mates with the second mating part, and the first detection element 31 is adapted to detect the distance between the first contouring part 221 and the second mating part.

[0042] During vehicle production, after the operator places the inspection fixture 100 at the designated position on the car door, the position of the first contouring part 22 on the car door coincides with the position of the spoiler on the car door. The first contouring part 22 simulates the actual assembly state of the spoiler on the car door and the second mating part on the car body. By observing the relative posture of the first contouring part 221 and the second mating part, the operator can quickly determine whether the relative posture of the spoiler and the second mating part meets the requirements, thereby quickly determining whether the positional accuracy of the car door on the car body meets the requirements. At the same time, the first inspection piece 31 detects the distance between the first contouring part 221 and the second mating part and transmits the detection data to the control unit. Thus, on the one hand, it can accurately determine whether the relative posture of the spoiler and the second mating part meets the requirements; on the other hand, the control unit can adjust the assembly parameters of the assembly robot based on the detection data, enabling the assembly robot to adjust the assembly position of the car door on the car body.

[0043] In this process, the first contouring part 22 simulates the shape of the spoiler. The spoiler is used as a reference to detect whether the relative posture of the door and the body meets the requirements. Since the size of the spoiler is relatively large, the size of the first contouring part 221 can also be relatively large. In this way, the size of the first contouring part 221 and the second mating part is also relatively large. The mating condition of the first contouring part 221 and the second mating part can better reflect the mating condition of the door and the body. Furthermore, since the spoiler is installed on the outermost side of the door, the difficulty of positioning the tooling 100 on the door is relatively low, and the difficulty of detecting the mating state of the tooling 100 simulating the spoiler and the second mating part is also relatively low.

[0044] In some embodiments of this utility model, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the door component also includes a door trim panel, a component mating part including a third mating part on the door trim panel, a body mating part including a fourth mating part, the third mating part being used to mate with the fourth mating part, the contouring part 20 including a second contouring part 23, the contouring part 21 including a second contouring part 231 on the second contouring part 23, the contour of the second contouring part 231 being adapted to the contour of the third mating part, the second contouring part 231 being provided with a second detection element 32, the detection fixture 100 being adapted to be placed on the door so that the second contouring part 231 mates with the fourth mating part to simulate the state of the third mating part mates with the fourth mating part, the second detection element 32 being adapted to detect the distance between the second contouring part 231 and the fourth mating part.

[0045] During vehicle production, after the operator places the inspection fixture 100 at the designated position on the car door, the position of the second contouring part 23 on the car door matches the position of the door trim panel on the car door. The second contouring part 23 simulates the actual assembly state of the door trim panel on the car door and the fourth mating part on the vehicle body. By observing the relative posture of the second contouring part 231 and the fourth mating part, the operator can quickly determine whether the relative posture of the door trim panel and the fourth mating part meets the requirements, thereby quickly determining whether the positional accuracy of the car door on the vehicle body meets the requirements. At the same time, the second inspection part 32 detects the distance between the second contouring part 231 and the fourth mating part and transmits the detection data to the control unit. Thus, on the one hand, it can accurately determine whether the relative posture of the door trim panel and the fourth mating part meets the requirements; on the other hand, the control unit can adjust the assembly parameters of the assembly robot based on the detection data, enabling the assembly robot to adjust the assembly position of the car door on the vehicle body.

[0046] In this process, the shape of the door trim panel is simulated by the second contouring part 23. The door trim panel is used as a reference to check whether the relative posture of the door and the body meets the requirements. Since the door trim panel is relatively large, the size of the second contouring part 231 can also be relatively large. In this way, the size of the second contouring part 231 and the fourth mating part is also relatively large. The mating condition of the second contouring part 231 and the fourth mating part can better reflect the mating condition of the door and the body. Furthermore, since the door trim panel is installed on the outermost side of the door, the difficulty of positioning the inspection fixture 100 on the door is relatively low, and the difficulty of simulating the mating state of the door trim panel and the fourth mating part by the inspection fixture 100 is also relatively low.

[0047] Preferably, there are multiple second contouring parts 23. For example, there may be two, three or four second contouring parts 23, and multiple contouring parts 20 are arranged at intervals on the tooling bracket 10.

[0048] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 6As shown, the first contouring part 221 is adapted to mate with the second mating part in the first direction, and the second contouring part 231 is adapted to mate with the fourth mating part in the second direction, wherein the first direction and the second direction intersect.

[0049] For example, the first contouring part 221 and the second mating part are mated in the X direction of the vehicle body, and the second contouring part 231 and the fourth mating part are mated in the Y direction of the vehicle body.

[0050] Therefore, the fit between the door and the body can be detected in two different directions, thereby improving the accuracy of door posture detection.

[0051] In some embodiments of this utility model, such as Figures 2-5 As shown, the component mating part includes a component mating edge, which is used to mate with the vehicle body mating part. The contouring part 21 includes a contouring edge 211, the contour of which is adapted to the contour of the component mating edge. The contouring edge 211 is adapted to mate with the vehicle body mating part to simulate the mating state between the component mating edge and the vehicle body mating part.

[0052] In other words, the contouring part 21 simulates the fit between the edge of the component fit part and the body fit part by fitting its edge with the body fit part. In this way, the fit between the contouring part 21 and the body fit part is larger, and the fit between the contouring part 21 and the door fit part can better reflect the fit between the door and the body, thereby further improving the assembly accuracy of the door on the body.

[0053] In some embodiments of this utility model, such as Figures 3-6 As shown, the contouring part 21 is also provided with an indicator 40. When the inspection fixture 100 is placed on the door, the direction of the contouring part 21 toward the body fitting part is the indicator direction. The indicator 40 is configured to extend from the contouring part 21 in the indicator direction with an adjustable length.

[0054] In this embodiment, both the first contouring part 221 and the second contouring part 231 are provided with an indicator 40.

[0055] During vehicle production, after the operator places the inspection fixture 100 at the designated position on the door, the indicator 40 is located between the contour part 21 and the body mating part. By observing the relative positional relationship between the indicator 40 and the body mating part, the operator can more quickly and accurately determine the relative posture between the contour part 21 and the body mating part. This can further improve production efficiency and the assembly accuracy of the door on the vehicle body.

[0056] The length of the indicator 40 extending out of the contour part 21 is adjustable. On vehicles with different tolerance requirements, the length of the indicator 40 extending out of the contour part 21 can be adjusted so that the inspection fixture 100 can be adapted to the assembly accuracy requirements of more vehicle models.

[0057] Preferably, the indicator 40 has a minimum length when it extends out of the contour portion 21. Based on the minimum length, the indicator 40 can continue to extend by a length less than or equal to 3 mm. For example, the length that the indicator 40 can continue to extend from the minimum length can be 0.5 mm, 1 mm, 1.2 mm, 1.5 mm, 2 mm, 2.3 mm or 3 mm.

[0058] In some embodiments of this utility model, such as Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, a threaded hole with an opening in the indicating direction is formed on the contour part 21, and the indicator 40 is a bolt that is threaded into the threaded hole.

[0059] Therefore, by turning the indicator 40 within the stroke range, the length of the indicator 40 extending out of the contour part 21 can be adjusted, and the position of the indicator 40 within the stroke range can be fixed. The operation is relatively simple, and it is relatively easy to arrange the indicator 40 on the contour part 21.

[0060] Preferably, the indicator 40 is provided with an internal hexagon, which the operator can use to adjust the indicator 40.

[0061] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the car door is provided with multiple positioning holes. The testing fixture 100 also includes multiple positioning pins 50, which are spaced apart on the fixture bracket 10. Each positioning pin 50 corresponds to a positioning hole and is adapted to fit into the positioning hole. For example, there can be two, three, or four positioning holes, and there can be two, three, or four positioning pins 50.

[0062] When the operator places the inspection fixture 100 on the car door, the positioning pin 50 and the positioning hole cooperate to position and limit the inspection fixture 100. On the one hand, this allows the inspection fixture 100 to be quickly placed on the car door and improves the positional accuracy of the inspection fixture 100 on the car door. On the other hand, the positioning pin 50 and the positioning hole cooperate to prevent the inspection fixture 100 from moving relative to the car door, so that the operator can perform visual inspection of the contour part 21 and the body mating part, as well as the inspection of the distance between the contour part 21 and the body mating part by the inspection piece 30, normally.

[0063] During the product design process, the number and arrangement of positioning pins 50 and positioning holes can be adjusted according to design needs, thereby meeting more product design requirements.

[0064] In some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the car door is also provided with multiple mating surfaces, and the inspection fixture 100 is also provided with multiple positioning surfaces 60. The multiple positioning surfaces 60 are arranged at intervals on the fixture bracket 10, and the positioning surfaces 60 correspond one-to-one with the mating surfaces. The positioning surfaces 60 are suitable for mating with the mating surfaces. For example, there can be two, three or four mating surfaces, and there can be two, three or four positioning surfaces 60.

[0065] When the operator places the inspection fixture 100 on the door, the positioning pin 50 extends into the positioning hole, and at the same time, the positioning surface 60 fits against the mating surface. In this way, the positioning pin 50 and the positioning surface 60 can position the inspection fixture 100 on the door in the X, Y and Z directions of the vehicle. The operation during the positioning process is relatively convenient and can further improve production efficiency.

[0066] Preferably, the tooling bracket 10 is provided with a plurality of positioning blocks, and the positioning surface 60 and the positioning pin 50 are both provided on the positioning blocks.

[0067] In some embodiments of this utility model, such as Figures 3-6 As shown, the detection component 30 is a telescopic ranging probe.

[0068] When the operator places the testing fixture 100 on the car door, the contour part 21 and the body mating part together compress the probe of the testing part 30. After the testing fixture 100 is in place, the telescopic distance measuring probe can measure the distance between the contour part 21 and the body mating part according to the compression of the probe.

[0069] It is understandable that the distance between the contouring part 21 and the body fitting part is small, and the area that can be measured is small. By measuring the distance between the contouring part 21 and the body fitting part using a telescopic ranging probe, the assembly position of the door can be preliminarily judged by whether the body fitting part contacts the probe. Furthermore, the operator can intuitively see whether the telescopic ranging probe is detecting the distance between the contouring part 21 and the body fitting part, thereby further improving the assembly accuracy of the door on the body.

[0070] In some embodiments of this utility model, the testing fixture 100 further includes a holding handle 70, which is disposed on the fixture bracket 10. By providing the holding handle 70, it is convenient for the operator to hold the testing fixture 100 during the testing process.
