The present utility model does not limit the specifications and specific types of the connecting plate of the car backrest recliner, but the structure of the working plate 1, the product placement groove 12, the vertical clamp 2 and the inspection module 3 is particularly suitable for a one-time rapid inspection of whether the outer contour dimensions of the connecting plate of the car backrest recliner and the aperture positions of the waist holes and positioning holes on the bottom and side walls of the connecting plate of the car backrest recliner and the positions of the anisotropic grooves are within the tolerances specified in the qualified design process.

[0034] In general, the detection fixture of the car backrest recliner connecting plate proposed by the present invention mainly includes: a working plate 1, a product placement slot 12, a vertical clamp 2 and a detection module 3, among which, you can refer to Figure 1 , which shows the arrangement relationship of the working plate 1, the product placement slot 12, the vertical clamp 2 and the detection module 3.

[0035] When the inspection fixture of the automobile backrest recliner connecting plate proposed by the present invention is used, the product to be inspected is placed in the product placement groove 12, and the vertical clamp 2 is driven to control the inspection fixture holding block 37 connected thereto to drive the bottom inspection fixture to enter the hole or groove to be inspected of the product to limit the product position or directly drive the vertical clamp 2 to press the product into the product placement groove 12 to limit the product position, and detect whether the inspection hole to be inspected inserted by the inspection fixture connected to the vertical clamp 2 is out of tolerance, and the needle gauge 32 and feeler gauge 33 of corresponding specifications are used to match the outer contour of the product and the product placement groove 12 to detect whether the outer contour size is out of tolerance, wherein the feeler gauge 33 detects the flat surface, and the needle gauge 32 detects the curved surface, and the adjuster hole detection block 34 is controlled to enter the side of the product where the recliner is installed, and detect whether the hole position of the product on the side of the recliner is correct, and the holding ball 311 is pushed to control the side hole push rod 313 to drive the positioning hole plug block to enter the interior of the product, and observe whether the hole position of the product side wall is accurate, and the inspection fixture holding block 37 controls the bottom The stop block 38 and the special-shaped groove plug block 39 enter the positioning hole at the bottom of the product, and the waist hole and the special-shaped groove judge whether the position tolerance and size tolerance meet the process requirements. It should be noted that the stop side of the stop block 38 enters the product positioning hole, indicating that the product aperture tolerance is unqualified. It enters the product positioning hole but cannot enter the reference positioning circular hole 15, indicating that the position tolerance is unqualified. The positioning pin 310 can enter the positioning socket 17, but the stop block 38 and the special-shaped groove plug block 39 cannot enter the product special-shaped groove and waist hole, indicating that the position tolerance of the special-shaped groove or waist hole is unqualified. The positioning pin 310 can enter the positioning socket 17, but the stop side of the stop block 38 also enters the waist hole, indicating that the size tolerance of the waist hole is unqualified. The automobile backrest adjuster connecting plate proposed by the utility model can be clamped once, and the product outer contour detection, side wall hole position detection, bottom positioning hole, waist hole, and special-shaped hole position and size inspection are completed. The detection efficiency is high and it is suitable for the detection of mass-produced automobile backrest adjuster connecting plates.

[0036] The top of the working plate 1 is provided with an integral positioning block 11, and a product placement groove 12 is provided in the middle of the top of the positioning block 11.

The bottom of the reference positioning waist hole 13 and the reference positioning special-shaped groove 14 are provided with a positioning socket 17, which is convenient for measuring the hole position. If the positioning detection of the inspection tool for inspecting the waist hole and special-shaped groove on the product depends solely on the corresponding waist hole and special-shaped groove shape groove, it is impossible to intuitively judge whether the bottom of the inspection tool is inserted into the groove, and the technician needs to withdraw the plug back and forth many times. The efficiency is poor, and a positioning socket 17 is added. If there is a problem with the positioning of the product, the part of the inspection tool used for inspection will not be able to be inserted. The top of the product placement slot 12 is located in the front and back of the product placement slot 12, and a chip removal groove 16 is provided that penetrates the side wall of the positioning placement block 11. During the inspection, the product will still have residual metal debris because the surface was simply cleaned with an air gun in the previous processing process. When the product is placed in the product placement slot 12 for inspection, some metal debris on the product will fall into the product placement slot 12. Accumulated debris will affect the inspection accuracy and scratch the surface of the product. The chip removal groove 16 can facilitate the cleaning of the debris in the product placement slot 12.
