[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a finished product testing machine for automotive seat belt guide rings, which includes a support frame 1, a frame 2 fixedly connected above the support frame 1, a control console 3 fixedly connected above the frame 2, a workbench 6 fixedly connected above the control console 3, and a pair of gantry frames 7 fixedly connected to both sides of the workbench 6.

[0027] A control panel 4 is fixedly connected to one side of the control panel 3, and a switch 5 is fixedly connected to the other side of the control panel 3.

[0028] Specifically: The operator starts the equipment via switch 5, and control panel 4 immediately enters working mode, displaying test data in real time. The car seat belt guide ring to be tested is placed on the worktable, and the system automatically enters the testing mode.

[0029] The inner wall of the gantry frame 7 is grooved to provide a limiting groove 8, and the limiting groove 8 is movably connected to a movable crossbeam 9.

[0030] Specifically: The limiting groove 8 on the inner wall of the gantry 7 guides the moving crossbeam 9 to slide up and down, so that it is accurately positioned above the guide ring to be tested.

[0031] The upper clamp 29 is fixedly connected to the lower part of the movable crossbeam 9.

[0032] Specifically: the upper clamp 29 is fixedly connected to the movable crossbeam 9 via the base 10. When the movable crossbeam 9 moves, the upper clamp 29 follows and forms an upward pulling force to perform a tensile test.

[0033] The upper clamp 29 includes: a base 10, a fixing groove 11, a locking strip 12, a handle 13, a fixing block 14, a locking handle 15, a mounting plate 16, a sensor 17, a connecting column 18, a clamp housing 19, a first bolt 20, a sleeve 21, a pull rod 22, a screw rod 23, an adjusting plate 24, a second bolt 25, jaws 26, and an anti-slip pad 27.

[0034] Specifically: the position of the clip 12 in the fixed groove 11 is adjusted by the handle 13 to accommodate guide rings of different specifications. The locking handle 15 is used to fix the fixing block 14 to ensure that the fixture remains stable during the inspection process. The sensor 17 monitors the clamping force in real time and feeds the data back to the control panel 4 through the connecting column 18. The system automatically judges whether the product is qualified. The screw 23 drives the pull rod 22 to perform preliminary coarse adjustment so that the jaws 26 approach the guide ring.

[0035] The top of the clip 12 is movably connected to the fixed groove 11, the handle 13 is fixedly connected to the outer wall of the clip 12, the fixed block 14 is fixedly connected to the top of the fixed block 14, the locking handle 15 is fixedly connected to one end of the fixed block 14, the mounting plate 16 is fixedly connected to one end of the fixed block 14, the sensor 17 is fixedly connected to one end of the mounting plate 16, the connecting post 18 is fixedly connected to one end of the sensor 17, and the clamp housing 19 is fixedly connected to one end of the connecting post 18.

[0036] Specifically: Hold the two handles 13 on the outer wall of the clamping strip 12 and smoothly slide the top of the clamping strip 12 along the track of the fixing groove 11 to the predetermined position. At this time, the fixing block 14 moves synchronously with the clamping strip, and the entire fixture assembly is initially fixed in the detection position by rotating the locking handle 15. The sensor 17 on the mounting plate 16 is then powered on and enters the detection state.

[0037] A sleeve 21 is fixedly connected to the fixture housing 19. The sleeve 21 is fixedly connected to one side of the fixture housing 19 with the first bolt 20. A pull rod 22 is fixedly connected to the sleeve 21.

[0038] Specifically: by rotating the first bolt 20, the pull rod 22 inside the sleeve 21 is driven to move axially, and the pull rod drives the screw 23 to achieve rapid initial positioning of the jaws 26.

[0039] The pull rod 22 is connected to the screw rod 23 for transmission, and the clamp housing 19 is fixedly connected to the adjusting plate 24. The adjusting plate 24 is threadedly connected to the second bolt 25, and the second bolt 25 is threadedly connected to the jaws 26. The inner wall of the jaws 26 is provided with anti-slip pads 27.

[0040] Specifically: the second bolt 25 cooperates with the adjusting plate 24 to make fine adjustments and lock, ensuring that the guide ring is firmly clamped, while the anti-slip pad 27 prevents damage to the workpiece surface.

[0041] Working Principle: After installation, the equipment is started. The gantry frame 7 and the limiting groove 8 structure ensure overall rigidity and reduce the impact of vibration on the detection. The moving beam 9 slides along the limiting groove 8, allowing the upper clamp 28 to be accurately positioned, avoiding measurement errors caused by mechanical deviations. In addition, the control panel 4 and switch 5 are located on opposite sides for convenient operation and improved human-machine interaction efficiency. The clamp adopts a multi-stage adjustment mechanism, including a screw 23 for coarse adjustment and a second bolt 25 for fine adjustment, ensuring that the guide ring is firmly clamped and the force is evenly distributed. The sensor 17 monitors the clamping force in real time and feeds back the data through the connecting column 18. The jaws 26 have embedded anti-slip pads to prevent scratches on the workpiece surface and enhance friction to prevent slippage during detection. The clamp adopts a sliding structure of the locking strip 12 and the fixing groove 11. With replaceable jaws, it can quickly adapt to guide rings of different specifications. The moving beam 9 provides adjustable stroke, reducing equipment modification costs and improving production line compatibility.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
