[0028] 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.

[0029] A fixture for an automotive seat side plate connection bracket in this embodiment relates to the technical field of fixtures. Through multiple sets of pin detection units 220, two sets of pressing and positioning units 210, and a profile detection unit 310, the specific side plate connection bracket 400 is fully positioned and fixed, and the profile accuracy and hole position accuracy of the side plate connection bracket 400 are verified.

[0030] Please refer to Figures 1 to 5 , A fixture for an automotive seat side plate connection bracket in this embodiment includes: a base 100, a hole position positioning component 200, and a profile detection component 300. The base 100 includes a seat body 110 and a profiling positioning seat 120. The seat body 110 serves as the support and fixing foundation of the fixture and can assist in the installation and connection of the positioning and detection units. The profiling positioning seat 120 is fixedly connected to the base 100, and the profiling positioning seat 120 can be fully fitted with the side plate connection bracket 400 to complete the positioning and limiting of the side plate connection bracket 400.

[0031] The hole position positioning component 200 includes two pressing and positioning units 210 and multiple pin detection units 220. The pressing and positioning unit 210 includes a clamp 211 and a positioning pin 212. A pressing block 211a for pressing the side plate connection bracket 400 is provided on the movable arm of the clamp 211. The pressing block 211a presses and fixes the side plate connection bracket 400, so that the side plate connection bracket 400 is closely fitted with the profiling positioning seat 120. A reference plane is formed between the pressing block 211a and the side plate connection bracket 400. The reference plane provides a stable reference plane for ensuring accurate detection of the hole position and profile of the side plate connection bracket 400. The positioning pin 212 passes through the side plate connection bracket 400 and is inserted into the profiling positioning seat 120, which can position the side plate connection bracket 400, thereby ensuring the relative position stability of the side plate connection bracket 400 during the detection process and reducing the hole position deviation.

[0032] At least one pin detection unit 220 is inserted into the profiling positioning seat 120 in the horizontal direction, and at least one pin detection unit 220 is inserted into the profiling positioning seat 120 in the vertical direction. The pin detection units 220 arranged in the horizontal and vertical directions are inserted into the profiling positioning seat 120, and can accurately measure the diameters and positions of the holes in different orientations in the side plate connection bracket 400 to ensure the accuracy of the hole position.

[0033] The profile detection component 300 includes at least one profile detection unit 310. The profile detection unit 310 is arranged relative to the profiling positioning seat 120 and can calibrate the outer profile of the side plate connection bracket 400. Through the profile detection unit 310, it can be detected whether the profile of the side plate connection bracket 400 is deformed to ensure that it meets the requirements of the designed profile.

[0034] In some embodiments, please refer to Figures 1 to 3 , the profiling positioning seat 120 includes a horizontal portion 121 and a vertical portion 122. The horizontal portion 121 is arranged parallel to the seat body 110, and the vertical portion 122 is arranged perpendicular to the seat body 110. The vertical portion 122 is fixedly connected to the horizontal portion to form an "L-shaped structure" for cooperating with the side plate connection bracket 400. The "L-shaped structure" provides a stable and accurate positioning reference. By cooperating with the side plate connection bracket 400, it can ensure that the side plate connection bracket 400 is stably fixed at a predetermined position during the detection process, thereby reducing the positioning error.

[0035] The through holes 123 on the vertical portion 122 and the horizontal portion 121 respectively cooperate with the hole positions of the side plate connection bracket 400. The pin detection unit 220 can be inserted into the holes of the side plate connection bracket 400 through the through holes 123, so as to measure the positions and sizes of the holes on the side plate connection bracket 400. The setting of the through holes 123 enables the pin detection unit 220 to accurately dock with the holes of the side plate connection bracket 400 to ensure the accuracy of the detection.

[0036] As a supplement, due to the arrangement of the vertical part 122 and the horizontal part 121, the inspection tool can detect the side plate connection bracket 400 from both horizontal and vertical directions. The multi-directional detection method improves the comprehensiveness of the detection and ensures the hole positions and dimensional accuracy of the side plate connection bracket 400 in all key directions.

[0037] As a further implementation, please refer to Figure 3 , the profiling positioning seat 120 further includes a positioning block 124. The positioning block 124 is embedded in the horizontal part 121 and the vertical part 122, which can provide a more accurate alignment reference, making the positioning of the side plate connection bracket 400 more stable during detection and reducing the measurement error caused by inaccurate positioning. At the same time, the embedding of the positioning block 124 enhances the structural strength and stability of the profiling positioning seat 120. By combining the positioning block 124 with the horizontal part 121 and the vertical part 122, the overall structure becomes more robust and can better withstand the mechanical forces generated during processing and measurement, ensuring reliability during long-term use.

[0038] A through hole 123 is opened on the positioning block 124. The positioning block 124 provides a fixed and accurate hole position reference, enabling the pin detection unit 220 to accurately insert into the through hole 123 to detect the hole position, thereby improving the accuracy of hole position detection.

[0039] In some embodiments, please refer to Figure 5 , the pin detection unit 220 includes a detection pin 221. The two ends of the pin detection unit 220 can respectively detect the position degree and size of the holes of the side plate connection bracket 400 to complete the calibration of the side plate connection bracket 400.

[0040] In the specific implementation process, a position degree detection head 221a is provided at one end of the detection pin 221. The position degree detection head 221a is inserted into the through hole 123 through the side plate connection bracket 400, thereby accurately determining the horizontal and vertical deviations of the hole position, and then evaluating whether the hole position meets the design requirements, improving the detection accuracy of the hole position and helping to discover the problem of hole position deviation.

[0041] An aperture go-no-go gauge 221b is assembled at the other end of the detection pin 221, which can be used to measure the actual size of the holes on the side plate connection bracket 400. The aperture go-no-go gauge 221b can detect whether the diameter of the hole is within the design tolerance range, ensuring that the size of the hole meets the specification requirements, improving the accuracy of the aperture, and helping to detect whether the size of the hole meets the manufacturing standards.

[0042] By integrating the position detector 221a and the hole diameter go / no-go gauge 221b on the same detection pin 221, the detection process of the hole position and the hole diameter is simplified. The inspector only needs to use one tool to complete the detection of the hole position and the hole diameter, improving the detection efficiency and reducing the operation complexity.

[0043] In some embodiments, a detection pin 221 is a special-shaped detection pin 221 adapted to the side plate connection bracket 400. A rectangular hole is provided on the side plate connection bracket 400. The cross-sections of both ends of the special-shaped detection pin 221 are rectangular, and both the hole diameter go / no-go gauge 221b and the position detector 221a are rectangular, which can calibrate the position and size of the rectangular hole.

[0044] In some embodiments, please refer to Figure 4 , the pressing block 211a is arranged relative to the horizontal portion 121. The pressing block 211a can cooperate with the horizontal portion 121 to form a space for pressing the side plate connection bracket 400 between the pressing block 211a and the horizontal portion 121. The reference plane is arranged parallel to the horizontal portion 121, providing a stable and consistent reference plane. The reference plane serves as the reference for detection, which helps to ensure that the contact and alignment between the pressing block 211a and the side plate connection bracket 400 are consistent each time detection is performed, thereby improving the detection accuracy.

[0045] A clamping groove 211b is provided on the pressing block 211a. The clamping groove 211b on the pressing block 211a provides a precise positioning point, enabling the positioning pin 212 to be firmly inserted into the clamping groove 211b. The positioning pin 212 will not displace during the measurement process, ensuring that the side plate connection bracket 400 can be accurately fixed at the predetermined position during detection.

[0046] It should be noted that the positioning pin 212 can be first inserted into the side plate connection bracket 400 to limit the side plate connection bracket 400. Then, the pressing pliers 211 are used to press the pressing block 211a against the side plate connection bracket 400. The clamping groove 211b of the pressing block 211a can pass through the positioning pin 212 to press the side plate connection bracket 400, avoiding interference between the pressing block 211a and the positioning pin 212.

[0047] In some embodiments, please refer to Figures 1 and Figure 2 , the profile detection unit 310 includes a first go / no-go gauge 311 and a second go / no-go gauge 312. The first go / no-go gauge 311 is arranged at one end of the vertical portion 122, and the second go / no-go gauge 312 is arranged at the other end of the vertical portion 122. The first go / no-go gauge 311 and the second go / no-go gauge 312 are respectively arranged at both ends of the vertical portion 122, and can measure the distances between both ends of the side plate connection bracket 400 and the vertical portion 122. The end-to-end measurement method enables the accurate detection of the profile of the side plate connection bracket 400, thereby identifying any possible profile deformation or deviation.

[0048] By setting two go-no-go gauges, profile detection can be performed at different positions of the side plate connection bracket 400, ensuring that the profile measurement from one end point to the other end point of the side plate connection bracket 400 is completely covered, and improving the comprehensiveness and consistency of profile detection.

[0049] As a further implementation, the profile detection assembly 300 further includes a flush gauge 320. The flush gauge 320 is arranged between the first go-no-go gauge 311 and the second go-no-go gauge 312, providing an accurate comparison benchmark for the outer profile of the side plate connection bracket 400. The flush gauge 320 can be in direct contact with the profile of the side plate connection bracket 400 to help the inspector accurately check whether the outer profile of the side plate connection bracket 400 meets the design requirements.

[0050] The setting of the flush gauge 320 enables an accurate contact surface to be formed between the outer profile of the side plate connection bracket 400 and the flush gauge 320, which can timely detect subtle deviations or deformations of the profile and improve the accuracy of detection.

[0051] Workflow:

[0052] 1. Place the prepared side plate connection bracket 400 in the profiling positioning seat 120, and make the holes of the side plate connection bracket 400 match the positioning holes of the profiling positioning seat 120.

[0053] 2. Insert the two positioning pins 212 into the holes of the side plate connection bracket 400 in sequence, and then control the pressing pliers 211 to press down the pressing block 211a. Next, insert multiple detection pins 221 into the through holes 123 that match the side plate connection bracket 400 respectively. If the go gauge passes or the no-go gauge stops, it is judged as OK; otherwise, it is judged as NG.

[0054] 3. Use the profile detection assembly 300 to detect the outer shape of the side plate connection bracket 400:

[0055] 1) The first go-no-go gauge 311 (2.5 - 3.5 mm) measures the distance between one end of the side plate connection bracket 400 and the vertical part 122; 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.

[0056] 2) The second go-no-go gauge 312 (2.7 - 3.3 mm) measures the distance between the other end of the side plate connection bracket 400 and the vertical part 122; if the go gauge (2.7 mm) can pass and the no-go gauge (3.3 mm) can stop, it is judged as OK. Otherwise, it is judged as NG.

[0057] 3) Use the ±0.5 flush gauge 320 to cooperate with the 0 line to detect whether the middle profile of the product is qualified.

[0058] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model 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 utility model should be covered by the present utility model.
