[0035] The following will specifically describe the preferred embodiments of the present invention with reference to the accompanying drawings. The accompanying drawings form a part of this application and are used together with the embodiments of the present invention to explain the principle of the present invention, rather than to limit the scope of the present invention.

[0036] A fixture for an automotive seat mounting foot in this embodiment relates to the technical field of fixtures. It is provided with a first profiling positioning seat 120 adapted to the first mounting foot 500 to fix the first mounting foot 500. The positioning pin 220, the pin detection unit 310, and the profile detection unit 410 cooperate with each other to check the hole positions and the outer shape of the first mounting foot 500.

[0037] Please refer to Figures 1 to 7 , a fixture for an automotive seat mounting foot in this embodiment includes: a base 100, a reference positioning component 200, a hole position positioning component 300, and a profile detection component 400. The base 100 includes a seat body 110 and a first profiling positioning seat 120 for adapting to the first mounting foot 500. The first profiling positioning seat 120 is fixedly connected to the seat body 110. The base 100 provides a stable support platform, and the first profiling positioning seat 120 is used for precise cooperation with the first mounting foot 500. The first profiling positioning seat 120 can match the outer shape structure of the mounting foot, thereby ensuring the correct positioning of the mounting foot in the fixture.

[0038] The reference positioning component 200 includes a pressing and positioning unit 210 and a positioning pin 220. One end of the positioning pin 220 is a tapered portion 221. At least two tapered portions 221 respectively pass through the first mounting foot 500 and are inserted into the positioning holes 121a of the first profiling positioning seat 120. The structure of the tapered portion 221 can make the mounting holes of the mounting foot completely aligned with the positioning holes 121a of the first profiling positioning seat 120, preventing the occurrence of hole position deviation and enabling accurate measurement results to be obtained when detecting the mounting holes.

[0039] The pressing and positioning unit 210 includes a clamp 211. The clamp 211 can act on the other end of the positioning pin 220. By applying pressure to the positioning pin 220 through the clamp 211, the tapered portion 221 of the positioning pin 220 is precisely matched with the positioning holes 121a of the mounting foot, so that the hole positions of the mounting foot are concentric with the hole positions of the profiling positioning seat.

[0040] The hole position positioning component 300 includes a pin detection unit 310. The pin detection unit 310 can pass through the first mounting foot 500 and be inserted into the positioning hole 121a of the first profiling positioning seat 120. By accurately detecting the position and size of the mounting hole, it can identify the hole position deviation caused by processing errors, ensuring that the mounting hole meets the design specifications.

[0041] The profile detection component 400 includes at least one profile detection unit 410. The profile detection unit 410 is arranged relative to the first profiling positioning seat 120. The profile detection unit 410 can accurately detect the outer profile of the mounting foot, identify the profile deformation problems occurring during the processing, so as to ensure that the outer profile of the mounting foot meets the design requirements.

[0042] In some embodiments, please refer to Figure 3 , a positioning portion 222 is provided at one end of the tapered portion 221 of the positioning pin 220 relatively far from the crimping pliers 211. The tapered portion 221 and the positioning are integrally arranged. The positioning portion 222 is inserted into the positioning hole 121a of the first profiling positioning seat 120, and the tapered portion 221 is inserted into the first mounting foot 500.

[0043] The function of the tapered portion 221 is to enable it to be inserted into the hole of the mounting foot more accurately through its gradually tapering structure, so that the positioning pin 220 can automatically adjust and be precisely matched with the hole position, ensuring that the positioning hole 121a of the mounting foot and the positioning hole 121a of the profiling positioning seat are completely concentric. The positioning portion 222 being inserted into the positioning hole 121a of the first profiling positioning seat 120 ensures that the positioning pin 220 has a fixed position in the first profiling positioning seat 120, so that the positioning pin 220 will not shift during the detection process, thus ensuring the consistency and accuracy of the detection.

[0044] When the tapered portion 221 is inserted into the hole position of the first mounting foot 500, it can automatically adjust to compensate for possible slight deviations, thereby reducing the detection error caused by the hole position deviation. The stability of the positioning portion 222 further enhances the rigidity of the overall system, avoiding the error caused by the instability of the detection tool itself.

[0045] In some embodiments, please refer to Figure 4 , a pressing member 211a for pressing the positioning pin 220 is provided on the movable arm of the crimping pliers 211. The pressing member 211a fixes the positioning pin 220 by applying pressure, keeping it in an accurate position, preventing the deviation caused by external force or vibration during the detection process, ensuring the stability of the positioning pin 220 in the positioning hole 121a of the mounting foot, and thus improving the accuracy of the hole position and profile detection.

[0046] By pressing the positioning pin 220, the hole positions of the mounting feet are ensured to be concentric with the positioning holes 121a of the profiling positioning seat, reducing the detection error caused by the displacement of the positioning pin 220, thereby improving the reliability and accuracy of the detection results.

[0047] The pressure applied by the pressing member 211a is relatively constant, which can prevent the positioning pin 220 from loosening or shifting during the detection process, especially when repeatedly detecting different workpieces. The stability of the positioning pin 220 directly affects the consistency of the detection, making the conditions of each detection the same, thereby ensuring the consistency of the results.

[0048] In some embodiments, referring to Figure 5 , the first profiling positioning seat 120 further includes a positioning block 121. The positioning block 121 is embedded in the first profiling positioning seat 120, and the positioning holes 121a are formed in the positioning block 121. Both the positioning pin 220 and the detection pin 311 can be inserted into the positioning holes 121a on the positioning block 121.

[0049] The positioning block 121 is embedded in the first profiling positioning seat 120, and the positioning block 121 can be replaced regularly. When the positioning holes 121a are worn or damaged, only the positioning block 121 needs to be replaced, instead of replacing the entire profiling positioning seat. The modular design of the positioning block 121 reduces the maintenance cost and time of the inspection tool.

[0050] In the specific implementation process, the positioning block 121 can usually be made of materials with higher strength and wear resistance (such as cemented carbide, steel or other wear-resistant materials) to ensure the accuracy and durability of the positioning holes 121a. Compared with directly machining the hole positions on the profiling positioning seat, the machining accuracy of the positioning holes 121a is higher and the service life is longer.

[0051] In some embodiments, referring to Figure 6 , the pin detection unit 310 includes a detection pin 311. The detection pin 311 integrates a position degree detection head 311a and a hole diameter go-no-go gauge 311b, and can simultaneously complete the detection of the position degree and size of the mounting hole in one operation, simplifying the detection steps, avoiding the time and labor costs required for multiple measurements, significantly improving the detection efficiency, and reducing the complexity of the measurement operation.

[0052] One end of the detection pin 311 is provided with a position degree detection head 311a. The position degree detection head 311a can detect the position degree of the mounting hole on the mounting foot. The position degree detection head 311a is specifically a cylinder and can be directly inserted into the first profiling positioning seat 120 for position degree detection. The other end of the detection pin 311 is provided with a hole diameter go-no-go gauge 311b. The hole diameter go-no-go gauge 311b includes two cylinders of different sizes, and there is a step between the two cylinders. The two cylinders of different sizes are respectively the maximum and minimum sizes of the hole diameter, so as to check the size.

[0053] In some embodiments, referring to Figure 1 and Figure 7 , the profile detection unit 410 includes a clearance plug gauge 411. The clearance plug gauge 411 is disposed on one side of the first profiling positioning seat 120. By measuring the distance between the bottom of the first mounting foot 500 and the edge of the profiling positioning seat, it can effectively determine whether the mounting foot is within the profile at the specified position. By accurately measuring the clearance between the mounting foot and the profiling positioning seat, it ensures that the profile of the mounting foot conforms to the design specifications, guaranteeing the matching accuracy of the mounting foot during subsequent assembly processes.

[0054] In some embodiments, continue to refer to Figure 1 and Figure 7 , the profile detection unit 410 further includes a flush gauge 412. The flush gauge 412 is fixedly connected to the seat body 110. The flush gauge 412 provides a reference surface such that the outer profile of the mounting foot can be aligned with it. The flush gauge 412 can detect whether the outer shape of the mounting foot is consistent with the design specifications, especially in detecting the flatness and geometric shape of the profile.

[0055] The flush gauge 412 can help control the accuracy of the outer profile, ensuring that the outer shape of each mounting foot conforms to the design standards, which helps improve the overall product quality.

[0056] In some embodiments, referring to Figure 2 and Figure 5 , a recess 122 adapted to the first mounting foot 500 is provided in the middle of the first profiling positioning seat 120. A protrusion is provided on the first mounting foot 500 opposite to the recess 122. The protrusion of the first mounting foot 500 cooperates with the recess 122 of the first profiling positioning seat 120 to achieve the relative fitting of the first profiling positioning seat 120 and the first mounting foot 500, completing the positioning and fixing of the first mounting foot 500.

[0057] The recess 122 structure ensures that the first mounting foot 500 can be accurately embedded in the positioning seat, keeping it in a stable position during the detection process, effectively avoiding measurement errors caused by inaccurate positioning, and guaranteeing the accuracy and consistency of the positioning.

[0058] In some embodiments, referring to Figure 7, the base 100 further includes a second profiling positioning seat 130 for adapting to the second mounting foot 600. The structure of the second mounting foot 600 is similar to that of the first mounting foot 500, and both have three mounting holes and protrusions connected to the outside. And the second mounting foot 600 and the first mounting foot 500 are used in cooperation and are jointly mounted on the same vehicle seat and the vehicle to fix the vehicle seat. At the same time, another set of reference positioning components 200, hole position positioning components 300, and contour detection components 400 are arranged on the seat body 110, which cooperate with each other to check the mounting holes and contours of the second mounting foot 600.

[0059] Integrating the second profiling positioning seat 130 and the corresponding detection components in the base 100 enables the operator to complete the detection of different mounting feet on the same platform, simplifies the detection process, reduces the time for equipment switching and operation complexity, and improves the detection efficiency and convenience.

[0060] Workflow:

[0061] First, place the first mounting foot 500 on the first profiling positioning seat 120, and place the second mounting foot 600 on the second profiling positioning seat 130, so that the reference plane of the mounting foot fits the profiling positioning seat.

[0062] Then, insert the positioning pins 220 into the corresponding positioning holes 121a in sequence, and naturally drive the pressing pliers 211 to drive the pressing member 211a to press down the positioning pins 220, so that the hole positions of the mounting foot and the profiling positioning seat are concentric.

[0063] Next, insert the detection pin 311. If the aperture gauge passes or the go-no-go gauge stops, it is judged as OK; otherwise, it is judged as NG.

[0064] Finally, use the clearance go-no-go gauge 411 and the flush gauge 412 to check the outer contour of the mounting foot. The clearance go-no-go gauge 411 measures the distance between the bottom of the mounting foot and the edge of the profiling positioning seat; if the go gauge (2.5 mm) can pass and the no-go gauge (3.5 mm) can stop, it is judged as OK; otherwise, it is judged as NG. Use the flush gauge 412 to cooperate with the 0 line to detect whether the flanging contour of the product is qualified.

[0065] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the present invention.
