[0005] The positioning support block includes a positioning block body, the upper end of which is provided with a workpiece positioning slot for engaging with the claws on the decorative strip workpiece.

A clamping handle is also rotatably mounted on the clamping hinge, and the middle part of the clamping handle is hinged to the clamping swing arm via a connecting rod. The clamping handle drives the clamping swing arm to reciprocate around the clamping hinge at the upper end of the clamping connecting seat, thereby pressing the decorative strip workpiece positioned on the conformal support plate of the decorative strip workpiece by the workpiece clamping block at the front end of the clamping swing arm, preventing vertical movement of the workpiece.

[0007] The left-side simulated loading and flipping mechanism includes a flipping hinge portion mounted on the upper end of the flipping mechanism mounting base.

[0009] The front-side simulated loading and flipping mechanism includes a flipping hinge portion mounted on the upper end of the flipping mechanism mounting base. A flipping swing connecting arm is rotatably mounted on the flipping hinge portion. A long strip-shaped front-side simulated flipping block is provided at the front end of the flipping swing connecting arm.

The flipping block operating handle facilitates the operation of the long strip-shaped front-side simulated flipping block. After the front-side simulated flipping block of the front-side simulated loading and flipping mechanism is swung downwards and closed, the flipping block locking nut is tightened, thereby putting the flipping mechanism into a simulated loading state, which is convenient for accurate measurement of the decorative strip workpiece. At the same time, the clamping mechanism clearance notch in the middle of the front-side simulated flipping block avoids the quick-clamping mechanism arranged in the middle.

[0010] The rear-side simulated loading and flipping mechanism includes a flipping hinge, which is fixedly mounted on the upper end of the flipping mechanism mounting base.

In addition, the clamping mechanism clearance notch in the middle of the rear-side simulated flipping block can avoid the quick clamping mechanism arranged in the middle.

[0018] according to Figures 1-5 The specific structure of this utility model is described in detail. The rear door exterior decorative strip inspection fixture includes a bottom inspection fixture base plate 1. A decorative strip workpiece conformal support plate 2, whose upper shape matches the shape of the decorative strip workpiece, is provided in the middle of the upper side of the inspection fixture base plate 1. The lower part of the conformal support plate 2 is connected to the inspection fixture base plate 1 via several connecting blocks. Several sets of vertically arranged positioning support blocks 3 are provided on the conformal support plate 2. Each positioning support block 3 is composed of a positioning block body 10, and the upper end of the positioning block body 10 is provided with a workpiece positioning groove 11 for engaging with the claws on the decorative strip workpiece. Furthermore, the upper surface of the positioning support block 3 is not higher than the upper surface of the conformal support plate 2. Thus, by engaging the multiple claws on the decorative strip workpiece with the corresponding workpiece positioning grooves 11 on the upper end of the positioning support block 3, the position of the decorative strip workpiece on the conformal support plate 2 is accurately positioned, effectively preventing horizontal movement of the workpiece.

[0019] Furthermore, several sets of quick clamping mechanisms 4 are respectively provided around the periphery of the decorative strip workpiece conformal support plate 2. The quick clamping mechanism 4 includes a vertically arranged clamping connecting seat 12. The lower end of the clamping connecting seat 12 is fixedly connected to the inspection fixture base plate 1. The upper end of the clamping connecting seat 12 is provided with a clamping hinge part 13. A clamping swing arm 14 is rotatably provided on the clamping hinge part 13. A workpiece clamping block 15 is provided on the lower side of the front end of the clamping swing arm 14, and the workpiece clamping block 15 is located above the decorative strip workpiece conformal support plate 2. Meanwhile, a clamping handle 16 is rotatably provided on the clamping hinge part 13. The middle part of the clamping handle 16 is hinged to the clamping swing arm 14 through a connecting rod. Thus, the clamping handle 16 is used to drive the clamping swing arm 14 to swing back and forth around the clamping hinge part 13 at the upper end of the clamping connecting seat 12. The workpiece clamping block 15 at the front end of the clamping swing arm 14 is used to press the decorative strip workpiece positioned on the decorative strip workpiece conformal support plate 2, preventing the workpiece from moving vertically.

[0020] On the left and right sides of the conformal support plate 2 for the decorative strip workpiece, a left simulated loading and turning mechanism 6 and a right simulated loading and turning mechanism 7 are respectively provided. The left simulated loading and turning mechanism 6 and the right simulated loading and turning mechanism 7 have similar structures. The left simulated loading and turning mechanism 6 includes a turning hinge part 17 disposed on the upper end of the turning mechanism mounting base 5. A turning swing connecting arm 18 is rotatably disposed on the turning hinge part 17. A left simulated turning block 19 is disposed at the front end of the turning swing connecting arm 18. A turning block locking nut 20 is also disposed between the turning swing connecting arm 18 and the turning hinge part 17. Similarly, the right simulated loading and turning mechanism 7 also includes a turning hinge part 17. A turning swing connecting arm 18 is rotatably disposed on the turning hinge part 17. A right simulated turning block 21 is disposed at the front end of the turning swing connecting arm 18. A turning block locking nut 20 is disposed between the turning swing connecting arm 18 and the turning hinge part 17. Then, after swinging down to close the simulated loading and turning blocks of the left and right simulated loading and turning mechanisms, tighten the turning block locking nut 20 to put the turning mechanism in the simulated loading state, which is convenient for accurate measurement of the decorative strip workpiece.

[0021] In addition, the front and rear sides of the decorative strip workpiece conformal support plate 2 are respectively provided with a front simulated loading and turning mechanism 8 and a rear simulated loading and turning mechanism 9. The front simulated loading and turning mechanism 8 and the rear simulated loading and turning mechanism 9 have similar structures. The front simulated loading and turning mechanism 8 includes a turning hinge part 17 provided on the upper end of the turning mechanism mounting base 5. A turning swing connecting arm 18 is rotatably provided on the turning hinge part 17. A long strip-shaped front simulated turning block 22 is provided at the front end of the turning swing connecting arm 18. A clamping mechanism avoidance notch 24 for avoiding the quick clamping mechanism 4 is provided in the middle of the front simulated turning block 22. A turning block operation handle 23 is also provided on the long strip-shaped front simulated turning block 22. A turning block locking nut 20 is provided between the turning swing connecting arm 18 and the turning hinge part 17. Furthermore, the rear simulated loading and flipping mechanism 9 also includes a flipping hinge part 17, on which a flipping swing connecting arm 18 is rotatably mounted. A long strip-shaped rear simulated flipping block 25 is mounted at the front end of the flipping swing connecting arm 18. A clamping mechanism clearance notch 24 is located in the middle of the rear simulated flipping block 25. A flipping block operating handle 23 is also mounted on the long strip-shaped rear simulated flipping block 25. A flipping block locking nut 20 for locking is located between the flipping swing connecting arm 18 and the flipping hinge part 17. Thus, the flipping block operating handle 23 facilitates the operation of the long strip-shaped simulated flipping block. After swinging downwards to close the simulated flipping blocks of the front and rear simulated loading and flipping mechanisms, tightening the flipping block locking nut 20 puts the flipping mechanism in a simulated loading state, facilitating accurate measurement of the decorative strip workpiece. Simultaneously, the clamping mechanism clearance notch 24 in the middle of the long strip-shaped simulated flipping block avoids the quick clamping mechanism 4 located in the middle.

[0022] When using this rear door exterior trim strip inspection fixture, firstly, the trim strip workpiece is placed on the trim strip workpiece conformal support plate 2 in the middle of the fixture base plate 1. Multiple claws on the lower side of the trim strip workpiece engage with the workpiece positioning slots 11 on the upper end of the corresponding positioning support blocks 3 to accurately position the workpiece and prevent horizontal movement. Then, the clamping handle 16 drives the clamping swing arms 14 of each quick-clamping mechanism 4 to swing downwards. The workpiece clamping blocks 15 at the front end of the clamping swing arms 14 press the trim strip workpiece positioned on the trim strip workpiece conformal support plate 2, thus preventing vertical movement. Next, the simulated loading and turning blocks of the left, right, front, and rear simulated loading and turning mechanisms are swung downwards to close, and the locking nuts 20 of each simulated loading and turning mechanism are tightened, putting the turning mechanism into a simulated loading state for accurate measurement of the trim strip workpiece.
