[0001] This invention belongs to the field of dimensional inspection, specifically a tooling and method for inspecting the position of a bent arm. Background Technology

[0002] The middle door arm assembly of a bus is one of the key components of the bus door system. It is mainly used to connect the door and the vehicle body, support the opening and closing movement of the door, and ensure the stability and safety of the door during operation. Figure 1 A passenger bus middle door curved arm assembly is disclosed, including a lower curved arm 101, an upper curved arm 102, a first connecting rod 103, and a second connecting rod 104. The lower curved arm 101 and the upper curved arm 102, both near the vehicle body, are connected via the first connecting rod 103. The bottom end of the first connecting rod 103 is connected to a lower vehicle body support 105, and the top end is connected to a upper vehicle body support 106. A lower door support 107 is fixed to the end of the lower curved arm 101 near the door, and an upper door support 108 is fixed to the end of the upper curved arm 102 near the door. The design and manufacturing of this curved arm assembly must ensure the accuracy of its placement and movement trajectory to ensure smooth door opening and closing and good sealing. Therefore, the curved arm assembly needs to be inspected for positional accuracy after manufacturing, and it can only be installed and used after passing inspection.

[0003] The current method for detecting the position accuracy of the middle door arm of a bus is as follows:

[0004] First, determine the reference point or reference surface for the bending arm. This process usually involves selecting a fixed hole or machined surface on the bending arm as the reference, and using tools such as a scribing platform, height gauge, or dial indicator for reference positioning. Then, use pins or plug gauges to check whether each hole on the bending arm meets the design requirements. Use go / no-go gauges to check whether the thickness or width of the bending arm meets the requirements.

[0005] This detection method is used in detection Figure 1 When disclosing the position of the middle door boom assembly of the bus, the following problems exist:

[0006] Firstly, Figure 1 The publicly disclosed bus middle door arm assembly is a large component, making it inconvenient to perform benchmark positioning using conventional tools such as scribing platforms and height gauges. The process involves many steps, and human error has a significant impact, making it difficult to accurately perform benchmark positioning, thus affecting the inspection accuracy.

[0046] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0047] like Figure 1 The curved arm assembly 1 shown includes a lower curved arm 101, an upper curved arm 102, a first connecting rod 103, and a second connecting rod 104. The lower curved arm 101 and the upper curved arm 102 near the vehicle body are connected by the first connecting rod 103; the bottom end of the first connecting rod 103 is connected to a lower vehicle body support 105, and the top end is connected to a upper vehicle body support 106; the lower curved arm 101 near the door is fixed to a lower door support 107; and the upper curved arm 102 near the door is fixed to an upper door support 108.

[0048] When installed in the middle door of a bus, the lower support 105 is fixed to the bottom of the bus body at the middle door location using bolts and other connecting components, while the upper support 106 is fixed to the upper part of the bus body at the middle door location using bolts and other connecting components. The bottom end of the connecting rod 103 is rotatably connected to the lower support 105, and the top end is rotatably connected to the upper support 106. After the lower support 105 and the upper support 106 are fixed to the bus body, the connecting rod 103 can rotate around its own axis. Therefore, it is necessary to check the position of the connecting rod 103 to ensure that after the curved arm assembly 1 is installed in the middle door of the bus, there is sufficient clearance between the connecting rod 103 and the bus body to meet its own rotation requirements.

[0049] The lower door support 107 is a shaft-like structure. The upper part of the shaft is an Ω-shaped connecting seat. The shaft and the connecting seat rotate and engage. The end of the upper curved arm 102 is welded to the side wall of the shaft. The connecting seat is fixed to the top of the door via bolts or other connecting components on both sides. After the connecting seat of the lower door support 107 is fixed to the door, its shaft can rotate around its own axis. Therefore, it is necessary to check the positional accuracy of the shaft of the lower door support 107 to ensure sufficient clearance between the shaft and the door after installation in the bus's middle door to meet its rotation requirements. Simultaneously, it is also necessary to check the mounting holes on the connecting seat of the lower door support 107 to ensure alignment with the corresponding mounting holes on the door, meeting installation requirements.

[0050] The upper door support 108 consists of two parts: an L-shaped mounting base and a round shaft head, the top of which is rotatably connected to the top plate of the mounting base. During installation, the side plate of the mounting base is fixed to the mounting platform in the middle of the door using connecting bolts and other connectors. To ensure successful installation, the mounting holes on the upper door support 108 need to be checked to ensure alignment with the corresponding mounting holes on the door; the clearance of the upper door support 108 needs to be checked to ensure alignment with the mounting platform on the door; and the position of the round shaft head of the upper door support 108 needs to be checked so that after the upper door support 108 is installed on the door, rotating the door ensures that the door's rotation center is on the axis between the round shaft head of the upper door support 108 and the lower door support 107, thus stabilizing the door's posture.

[0051] This invention provides a tooling for detecting the position of a bent arm, such as... Figure 2 As shown, it includes a base 2; on the base 2, according to the theoretical dimensions of the curved arm assembly 1, there are a support platform 1 6 adapted to the lower support 105 of the vehicle body, a support platform 2 7 adapted to the upper support 106 of the vehicle body, a support platform 3 8 adapted to the lower support 107 of the door, and a support platform 4 9 adapted to the upper support 108 of the door.

[0052] Support platform 16, which is adapted to the underbody support 105, is used to simulate the installation location of the underbody support 105 at the middle door of the bus. Support platform 27, which is adapted to the body support 106, is also used to simulate the installation location of the underbody support 105 at the middle door of the bus. Support platforms 38 and 49 are similarly designed. Therefore, support platforms 16, 27, 38, and 49 are designed based on the theoretical fit relationship between the middle door of the bus and the curved arm assembly 1.

[0053] The support table one 6 is provided with a main reference hole 13 matched with the mounting hole on the lower body support 105, and is provided with a main positioning pin 14 matched with the main reference hole 13. The support table one 6 is used for supporting the lower body support 105. After the lower body support 105 is placed on the support table one 6, the main positioning pin 14 is inserted into the mounting hole of the lower body support 105 and the main reference hole 13 on the support table one 6 to position.

[0054] Similarly, the support table two 7 is provided with a secondary reference hole 15 matched with the mounting hole on the upper body support 106, and is provided with a secondary positioning pin 16 matched with the secondary reference hole 15.

[0055] The support table three 8 is provided with a detection hole one 17 matched with the mounting hole on the lower door support 107, and is provided with a position pin one 18 matched with the detection hole one 17.

[0056] The support table four 9 is provided with a detection hole two 19 matched with the mounting hole on the upper door support 108, and is provided with a position pin two 20 matched with the detection hole two 19.

[0057] The base 2 is provided with a detection seat one 10 for detecting the connecting rod one 103, a detection seat two 11 for detecting the lower door support 107, and a detection seat three 12 for detecting the upper door support 108.

[0058] The top end of the detection seat one 10, the detection seat two 11 and the detection seat three 12 are provided with a vertical detection surface 121 and a horizontal detection surface 122, which form an L-shaped detection area.

[0059] The main positioning pin 14 and the main reference hole 13 are used for positioning the lower body support 105, and the secondary positioning pin 16 and the secondary reference hole 15 are used for positioning the upper body support 106, so as to determine the detection reference point of the arm bending assembly 1, that is, the main reference hole 13 and the secondary reference hole 15 on the tooling are used as the detection reference point. The traditional installation hole of the arm bending assembly 1 is used as the detection reference, which is converted into the main reference hole 13 and the secondary reference hole 15 of the tooling as the reference point, so that all the arm bending assemblies detected by the detection tooling have the same detection reference point, which ensures the consistency of the detection, thereby ensuring the accuracy of the detection.

[0060] Since each connecting rod 103 has a certain length, the more detection points, the higher the detection accuracy; however, the more detection points, the longer the detection time. In order to balance the detection accuracy and save the detection time, preferably, the detection seat 10 is provided with two, respectively, the left detection seat 10B and the right detection seat 10A arranged along the theoretical extension direction of the connecting rod 103. The theoretical extension direction of the connecting rod 103 refers to the extension direction of the connecting rod 103 of the elbow assembly 1 in the theoretical design state. The left detection seat 10B detects the left side section of the connecting rod 103, and the right detection seat 10A detects the right side section of the connecting rod 103. The two detection points have higher detection accuracy than one detection point, and the time consumed is not too long.

[0061] In order to stably install the elbow assembly 1 to be detected in place and avoid position change during the detection process, in the embodiment, the quick clamps 3, 4 and 5 are arranged on the base 2; the quick clamp 3 is located beside the support table 6, the lower body support 105 is positioned behind the support table 6, and the pressure head of the quick clamp 3 is opposite to the upper and lower body support 105 to clamp the upper and lower body support 105; the quick clamp 4 is located beside the support table 7, the upper body support 106 is positioned behind the support table 7, and the pressure head of the quick clamp 4 is opposite to the upper and lower support table 7 to clamp the upper body support 106;

[0062] Since the gap between the L-shaped mounting seat of the door upper support 108 and the support table 4 needs to be detected, the L-shaped mounting seat of the door upper support 108 cannot be directly placed on the support table 4. In the embodiment, the quick clamp 5 is located beside the support table 4, and the pressure head of the quick clamp 5 downwardly abuts against the side surface of the door upper support 108 after the door upper support 108 is positioned on the support table 4. After the elbow assembly 1 is horizontally placed on the detection tool, the quick clamp 5 only limits the mounting seat of the door upper support 108 at the top, so as to avoid the position change of the elbow assembly 1 after the plug is inserted into the gap between the L-shaped mounting seat of the door upper support 108 and the support table 4, thereby affecting the detection accuracy.

[0063] The hydraulic cylinder can be vertically arranged as a clamp, and the corresponding components of the elbow assembly 1 are pressed downwardly by the piston rod end of the hydraulic cylinder. In the embodiment, the quick clamps 3, 4 and 5 each include a support leg 501, a rotating arm 502 and a pressing shaft 503. The rotating arm 502 is cantilevered mounted on the top of the support leg 501 and is rotationally connected with the support leg 501, and the pressing shaft 503 is vertically arranged on the cantilevered end of the rotating arm 502, and the bottom end of the pressing shaft 503 is a pressure head. The clamp with the above structure can make the pressure head of the pressing shaft 503 press the corresponding components of the elbow assembly 1 by forward rotation of the rotating arm 502, and the pressure head of the pressing shaft 503 is withdrawn by reverse rotation of the rotating arm 502.

[0064] For a reasonable layout, support plates 504 are fixedly distributed on the side of the base 2 near support platform 6 and the side near support platform 7. The bottom ends of the legs 501 of quick clamp 3 and quick clamp 4 are supported on the corresponding support plates 504; the bottom ends of the legs 501 of quick clamp 3 are supported on the top surface of the base 2.

[0065] To ensure the supporting strength of the base 2 while reducing the overall neutrality of the device, preferably, the base 2 includes a square frame 201 formed by square steel tubes and a platform plate 202 laid on the top surface of the square frame 201.

[0066] The method for detecting the position of a boom using a boom position detection fixture includes the following steps:

[0067] Step 1, such as Figure 3 As shown, gently place the arm assembly 1 to be inspected on the arm position detection fixture, adjust the corresponding hole positions, so that the lower support 105 of the vehicle body is completely in contact with the support platform 1 6; the upper support 106 of the vehicle body is completely in contact with the support platform 2 7; and the lower support 107 of the door is completely in contact with the support platform 3 8.

[0068] Step 2: Insert the main positioning pin 14 into the main reference hole 13, insert the secondary reference hole 15 into the secondary reference hole 15, and insert the position pin 20 into the detection hole 2 19.

[0069] Step 3: Install quick clamp one (3), quick clamp two (4), and quick clamp three (5);

[0070] Step 4: Check the position of the lower door support 107, the upper door support 108, and the connecting rod 103.

[0071] Step four involves checking the position of the lower door support 107, including the following steps:

[0072] Insert the position pin 18 into the mounting hole and the test hole 17 on the lower door support 107. If the mounting hole on the lower door support 107 satisfies the position pin 18, it means that the mounting hole on the lower door support 107 is qualified.

[0073] like Figure 5 As shown, a go / no-go gauge is used to check the gap 21 between the vertical testing surface 121 of the testing seat 11 and the lower door support 107; a go / no-go gauge is inserted into the gap 22 between the horizontal testing surface 122 of the testing seat 11 and the lower door support 107. The testing seat 11 is used to check the positional accuracy of the connecting seat of the lower door support 107. If both gap 21 and gap 22 meet the requirements of the go / no-go gauge, it indicates that the positional accuracy of the connecting seat of the lower door support 107 is qualified.

[0074] The positional accuracy of the door support 108 is checked, including the following steps:

[0075] As shown in Figure 7 , the gap three 23 between the top surface of the support table four 9 and the upper door support 108 is detected by using a go-no-go gauge, and the gap four 24 between the side surface of the support table four 9 and the upper door support 108 is detected by using a go-no-go gauge. The go-no-go gauge is mainly used to detect the position degree of the L-shaped mounting seat of the upper door support 108.

[0076] If the gap three 23 and the gap four 24 meet the go-no-go gauge requirements, it means that the position degree of the L-shaped mounting seat of the upper door support 108 meets the requirements.

[0077] As shown in Figure 6 , the gap five 25 between the vertical detection surface 121 of the detection seat three 12 and the upper door support 108 is detected by using a go-no-go gauge, and the gap six 26 between the horizontal detection surface 122 of the detection seat three 12 and the upper door support 108 is detected by using a go-no-go gauge. The detection seat three 12 is mainly used to detect the position degree of the round shaft head of the upper door support 108. If the gap five 25 and the gap six 26 meet the go-no-go gauge requirements, it means that the position degree of the round shaft head of the upper door support 108 meets the requirements.

[0078] The position degree of the connecting rod one 103 is detected, including the following steps:

[0079] As shown in Figure 4 , the gap seven 27 between the vertical detection surface 121 of the detection seat one 10 and the connecting rod one 103 is detected by using a go-no-go gauge, and the gap eight 28 between the horizontal detection surface 122 of the detection seat one 10 and the connecting rod one 103 is detected by using a go-no-go gauge. If the gap seven 27 and the gap eight 28 meet the go-no-go gauge requirements, it means that the position degree of the connecting rod one 103 is qualified.
