[0003] During the manufacturing process of automotive trailing arm brackets, high dimensional accuracy is required. To ensure product dimensional compliance, product inspection is essential. Traditionally, this method uses a three-dimensional coordinate measuring machine (CMM) for spatial position detection. The part being measured is placed within its permitted measurement space and the numerical values of each point on the surface of the part at different spatial coordinate positions are accurately measured. Computer processing then creates a fitting representation of measurement elements, such as circles, spheres, cylinders, cones, and curved surfaces. Mathematical calculations are then used to obtain geometric measurement data, including shape and position tolerances.

[0004] This detection method requires programming first, then positioning the product, and then measuring the product according to the program. After the product is tested, a report is issued, and then the report is analyzed to determine whether it is qualified.

[0030] The present invention is further described below with reference to the accompanying drawings and specific embodiments to facilitate understanding of the present invention. The methods used in the present invention are conventional methods unless otherwise specified; the raw materials and devices used are conventional commercially available products unless otherwise specified.

[0031] Example:

[0032] like Figures 1 to 6As shown, the utility model provides a trailing arm bracket spatial position detection device, including a detection platform 1, on which a trailing arm mounting hole detection seat 2 and a bracket mounting hole detection seat 3 are provided, and both the trailing arm mounting hole detection seat 2 and the bracket mounting hole detection seat 3 are provided with a detection pin 5 for detecting the corresponding hole position on the trailing arm bracket 4, the trailing arm mounting hole detection seat 2 is slidably mounted on a guide rail 6, and the guide rail 6 is fixedly mounted on the detection platform 1, and the trailing arm mounting hole detection seat 2 is provided with an insertion mechanism 7 for facilitating the insertion of the detection pin 5.

[0033] The bottom of the trailing arm bracket 4 is provided with two trailing arm mounting holes 8 , and the top is provided with four bracket mounting holes 211 . Each of the trailing arm mounting holes 8 is provided with two bracket mounting holes 211 .

[0034] Furthermore, the insertion mechanism 7 includes a mounting plate 71, a connecting plate 72, a rotating plate 73, a convex plate 74 and a fixing rod 75. The mounting plate 71 is fixedly mounted on the towing arm mounting hole detection seat 2. The rotating plate 73 is rotatably mounted on the outer side of the mounting plate 71. The other end of the rotating plate 73 is rotatably connected to the two ends of the connecting plate 72. The convex plate 74 is fixedly mounted on both ends of the connecting plate 72. One end of the fixing rod 75 passes through the towing arm mounting hole detection seat 2 and is fixedly connected to the detection pin 5, and the other end is rotatably connected to the convex plate 74.

[0035] When it is necessary to insert the detection pin 5 into the trailing arm mounting hole 8 for position detection, the connecting plate 72 is rotated upward. The rotation of the connecting plate 72 drives the protruding plate 74 to move inward, and then drives the fixing rod 75 to move inward, and finally drives the detection pin 5 to be inserted into the trailing arm mounting hole 8 for detection.

[0036] Furthermore, there are two trailing arm mounting hole detection seats 2, and the trailing arm mounting hole detection seats 2 include a mounting seat 21 and a limit seat 22. The mounting seat 21 is fixedly mounted on the detection platform 1, and the limit seat 22 is slidably connected to the guide rail 6. A placement groove 9 for placing the trailing arm mounting hole 8 on the trailing arm bracket 4 is formed between the limit seat 22 and the mounting seat 21. An adjustment mechanism 10 is connected to the two limit seats 22, and the adjustment mechanism 10 is used to synchronously adjust the width of the placement groove 9.

[0037] Furthermore, the adjustment mechanism 10 includes a connecting block 101, a sliding rod 102, a sliding groove 103 and a slide plate 104. The connecting block 101 is fixedly mounted on the corresponding limiting seat 22. The sliding rod 102 is fixedly mounted on the connecting block 101. Two sliding grooves 103 are provided on the slide plate 104. The distance between the two sliding grooves 103 gradually tightens toward the limiting seat 22, and the sliding rod 102 slides along the corresponding sliding groove 103.

[0038] When in use, pull the two limit seats 22 to move synchronously toward the middle along the guide rail 6. The movement of the limit seats 22 drives the movement of the connecting block 101, and then drives the sliding rod 102 on the connecting block 101 to move along the sliding groove 103, realizing the synchronous centering movement of the two limit seats 22, making it convenient to place the towing arm mounting hole 8 on the towing arm bracket 4 into the corresponding placement groove 9.

[0039] Furthermore, the end of the skateboard 104 away from the connecting block 101 is connected to a connecting rod 11, and a limiting groove 12 is provided on the skateboard 104. One end of the connecting rod 11 is inserted into the limiting groove 12, and the other end is fixedly connected to a fixing seat 13 fixed on the detection platform 1. The end of the connecting rod 11 inserted into the limiting groove 12 is fixedly installed with a limiting block 14, and the width of the limiting block 14 is greater than the width of the notch of the limiting groove 12. Limiting frames 221 are set on both sides of the skateboard 104, and the limiting frames 221 are fixed on the detection platform 1.

[0040] Furthermore, a spring 15 is provided in the limiting groove 12 , one end of the spring 15 is fixedly connected to the groove wall of the limiting groove 12 , and the other end of the spring 15 is fixedly connected to the limiting block 14 .

[0041] When the two limit seats 22 move synchronously toward the middle, the slide plate 104 is driven to move toward the direction of the connecting rod 11, and the spring 15 in the limit groove 12 is compressed. The compression of the spring 15 will exert pressure on the limit block 14. Since the width of the limit block 14 is greater than the width of the notch of the limit groove 12, the limit block 14 can be prevented from detaching from the limit groove 12.

[0042] When the trailing arm mounting hole 8 is placed in the placement groove 9 , the compressed spring 15 can quickly drive the slide plate 104 to move forward, thereby achieving a rapid reset of the limit seat 22 .

[0043] Furthermore, a flip mechanism 16 is provided on the bracket mounting hole detection seat 3 , and the flip mechanism 16 is used to adjust the position of the bracket mounting hole detection seat 3 .

[0044] Furthermore, the flipping mechanism 16 includes a flipping bracket 161, an extension plate 162, a roller shaft 163 and a fixing bolt 164. The flipping bracket 161 is fixedly mounted on the detection platform 1, and the extension plate 162 is rotatably connected to the roller shaft 163 fixedly mounted on the flipping bracket 161. The top of the extension plate 162 is fixedly mounted with the bracket mounting hole detection seat 3, and the fixing bolt 164 fixes the extension plate 162 to the flipping bracket 161.

[0045] Specifically, in this embodiment, two bracket mounting hole detection seats 3 are fixedly mounted on each of the extension plates 162 to facilitate detection of the positions of the two bracket mounting holes 211 on both sides of the trailing arm bracket 4 .

[0046] Furthermore, a positioning bracket 17 is installed below the bracket mounting hole detection seat 3, and the positioning bracket 17 is fixedly installed on the detection platform 1. A positioning seat 18 is installed on the top of the positioning bracket 17, and a height adjustment device 19 is provided on the positioning seat 18. The height adjustment device 19 is used to adjust the distance between the positioning seat 18 and the bracket mounting hole detection seat 3.

[0047] Furthermore, the height adjustment device 19 includes a protrusion 191, a groove 192, a turning handle 193 and a limiting plate 194. The protrusion 191 is fixedly installed on the bottom of the positioning seat 18, and the groove 192 is opened on the top of the positioning bracket 17. The width of the groove 192 is greater than the width of the protrusion 191 and less than the length of the protrusion 191. A positioning rod 20 is fixedly installed at the center of the groove 192. The positioning seat 18 is sleeved on the positioning rod 20 and is slidably connected to it. The turning handle 193 is fixedly installed on the side of the positioning seat 18, and the limiting plate 194 is installed on the positioning bracket 17. The limiting plate 194 is used to limit the turning handle 193.

[0048] Place the bracket mounting hole 211 of the trailing arm bracket 4 on the corresponding positioning seat 18, pull the handle 193 upward to make the positioning seat 18 move upward along the positioning rod 20, thereby moving the protrusion 191 out of the groove 192, and then rotate the handle 193 to the position of the limit plate 194. At this time, the position of the bracket mounting hole 211 is limited between the positioning seat 18 and the bracket mounting hole detection seat 3, so that the detection pin 5 on the bracket mounting hole detection seat 3 is inserted into the bracket mounting hole 211 for position detection.

[0049] The working principle of this embodiment is as follows:

[0050] First, according to the specific size of the trailing arm bracket 4, the flip mechanism 16 is used to adjust the position of the corresponding detection pin 5 and set it at a specified position.

[0051] During testing, the limit seat 22 is pulled to move synchronously to the center, and the trailing arm mounting hole 8 is placed in the corresponding placement slot 9. Then, under the action of the spring 15, the limit seat 22 can be quickly reset, and then the insertion mechanism 7 is used to insert the corresponding detection pin 5 into the trailing arm mounting hole 8 for position detection. Then, the position of the positioning seat 18 is adjusted upward to confine the four bracket mounting holes 211 between the positioning seat 18 and the bracket mounting hole detection seat 3, and then the detection pin 5 on the bracket mounting hole detection seat 3 is inserted into the bracket mounting hole 211 for position detection. If the corresponding size standards are met, the detection pin 5 on the trailing arm mounting hole detection seat 2 will fit with the trailing arm mounting hole 8, and the detection pin 5 on the bracket mounting hole detection seat 3 will fit with the bracket mounting hole 211.

[0052] In the description of the present invention, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inside", "outside", "back", "middle", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0053] However, the above description is merely a specific embodiment of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the patent of the present invention should still fall within the scope covered by the claims of the present invention.
