[0020] This utility model provides a detection and positioning fixture for automotive trim strip inspection, including a mounting plate 101, a guide ring plate 102, and two clamping mechanisms. Each clamping mechanism includes a housing 103, a holding rod 104, a ring 105, a spring 106, an arc plate 107, a U-shaped plate 108, two rotating shafts 109, a connecting rod 110, a locking block 111, a soft pad 112, a guide rail 113, and a slider 114. The mounting plate 101 has a contour groove 115, and the connecting rod 110 has a locking groove 116.

[0021] In this specific embodiment, the automotive trim strip is placed into the contour groove 115. The contour groove 115 is designed according to the current automotive trim strip shape and can accommodate curved or uniquely shaped trim strips. The guide ring plate 102 guides the automotive trim strip, facilitating its entry into the contour groove 115 and enabling more accurate positioning, thus improving installation efficiency. Before installation, the abutment rod 104 is pulled. After installation, the abutment rod 104 is released, and under the action of the spring 106, the abutment rod 104 returns to its original position, causing the arc plate 107 to abut against the trim strip. The arc plates 107 in the two clamping mechanisms are connected to the corresponding abutment rods 104 through their outer and inner walls, respectively, allowing the arc plates 107 to abut against the trim strip through different surfaces. Thus, this device can quickly and accurately position and fix the trim strip without deviation or dimensional error, facilitating subsequent inspection on the fixture and improving the product qualification rate.

[0022] The mounting plate 101 has a contoured groove 115. Two clamping mechanisms are symmetrically arranged on the mounting plate 101. The housing 103 is fixedly connected to the upper end of the mounting plate 101. One end of the abutment rod 104 passes through the housing 103 and is fixedly connected to the arc plate 107. The ring 105 is fixedly sleeved on the outside of the abutment rod 104 and located inside the housing 103. The two ends of the spring 106 are fixedly connected to the inner wall of the housing 103 and the ring 105, respectively. The guide ring plate 102 is arranged on the mounting plate 101. The car trim strip is placed into the contour groove 115, which is designed according to the current car trim strip shape and can accommodate curved or uniquely shaped trim strips. The guide ring plate 102 guides the car trim strip, making it easier for it to enter the contour groove 115 and positioning it more accurately, thus improving installation efficiency. Before installation, the abutment rod 104 is pulled. After installation, the abutment rod 104 is released, and under the action of the spring 106, the abutment rod 104 returns to its original position, causing the arc plate 107 to abut against the trim strip. The arc plates 107 in the two clamping mechanisms are connected to the corresponding abutment rods 104 through their outer and inner walls, respectively, so that the arc plates 107 can abut against the trim strip through different surfaces. Thus, the device can quickly and accurately position and fix the trim strip without deviation or dimensional error, facilitating subsequent inspection on the fixture and improving the product qualification rate.

[0023] Secondly, the connecting rod 110 has a slot 116, the two rotating shafts 109 are respectively fixedly connected to the abutment rod 104, the U-shaped plate 108 is rotatably connected to the two rotating shafts 109, the connecting rod 110 is fixedly connected to the U-shaped plate 108, and the locking block 111 is fixedly connected to the upper end of the mounting plate 101. To facilitate operation, when the abutment rod 104 is pulled, the connecting rod 110 can be pulled, thereby moving the U-shaped plate 108, the two rotating shafts 109, and the abutment rod 104. Then, by rotating the U-shaped plate 108 and the two rotating shafts 109, the connecting rod 110 is rotated, causing the slot 116 to engage with the locking block 111, thus limiting the connection rod 110 and the abutment rod 104. This facilitates the placement of the decorative strip into the contour groove 115. After the decorative strip is fully inserted, the connecting rod 110 and the U-shaped plate 108 are rotated again, and then the engagement between the slot 116 and the locking block 111 is released. This causes the abutment rod 104 to return to its original position under the action of the spring 106, causing the arc plate 107 to abut against the decorative strip. The arc plate 107 in the two clamping mechanisms clamps the decorative strip.

[0024] Meanwhile, the soft pad 112 is fixedly connected to the arc plate 107 and is located at the end of the arc plate 107 away from the abutment rod 104. The soft pad 112 prevents the arc plate 107 from directly contacting the decorative strip during clamping, thus avoiding scratching or abrading the decorative strip.

[0025] Furthermore, the guide rail 113 is fixedly connected to the inner wall of the housing 103, one end of the slider 114 is slidably adapted to the guide rail 113, and the other end of the slider 114 is fixedly connected to the abutment rod 104. The guide rail 113 is located on the inner top wall of the housing 103, the locking block 111 is fitted into the locking groove 116, and the guide ring plate 102 is located above the contour groove 115. When the abutment rod 104 moves, it drives the slider 114 to move within the guide rail, thereby improving the stability of the abutment rod 104 during movement.

[0026] When using the inspection and positioning fixture for automotive trim strips of this utility model, the automotive trim strip is placed into the contour groove 115. The contour groove 115 is designed according to the current automotive trim strip shape and can adapt to curved or uniquely shaped trim strips. The guide ring plate 102 guides the automotive trim strip, facilitating its entry into the contour groove 115 for more accurate positioning and improved installation efficiency. Before installation, the holding rod 104 is pulled; after installation, the holding rod 104 is released. Under the action of the spring 106, the... The abutment rod 104 returns to its original position, causing the arc plate 107 to abut against the decorative strip. The arc plates 107 in the two clamping mechanisms are connected to the corresponding abutment rods 104 via their outer and inner walls, respectively. This allows the arc plates 107 to abut against the decorative strip through different surfaces. Consequently, the device can quickly and accurately position and fix the decorative strip without deviation or dimensional error, facilitating subsequent inspection on the fixture and improving the product's pass rate. For ease of operation, when pulling the abutment rod 104, it can be pulled... The connecting rod 110 is moved, thereby moving the U-shaped plate 108, the two rotating shafts 109, and the abutment rod 104. Then, by rotating the U-shaped plate 108 and the two rotating shafts 109, the connecting rod 110 is rotated, causing the slot 116 to mate with the block 111, thereby limiting the connection rod 110 and the abutment rod 104, thus facilitating the insertion of the decorative strip into the contour groove 115. After the decorative strip is fully inserted, the connecting rod 110 and the U-shaped plate 108 are rotated again, and then the slot 116 is removed. The cooperation of the 6th clamping block 111 causes the abutment rod 104 to return to its original position under the action of the spring 106, so that the arc plate 107 abuts against the decorative strip. Through the arc plate 107 in the two clamping mechanisms, the decorative strip can be clamped. The soft pad 112 prevents the arc plate 107 from directly contacting the decorative strip when clamping it, thus avoiding scratching the decorative strip. When the abutment rod 104 moves, it drives the slider 114 to move within the slide rail, thereby improving the stability of the abutment rod 104 when it moves.
