[0026] During the test, the automobile sunroof mechanical component 1 to be tested is fixed on the mechanical component positioning device 5 of the measuring table, and the push-pull rod 2 is manually connected to the slider of the automobile sunroof mechanical component 1 and the force sensor 3. The push-pull drive device 4 then drives the force sensor 3 at a speed of 10 mm / s from the starting position of the part to the highest point of the slide and then to the end of the slide. The sliding force is measured and whether it is qualified is automatically determined. The push-pull drive device 4 is best selected from a servo motor, but can also be a cylinder.

[0027] The measuring platform is also fixedly mounted with a linear guide rail 6 extending linearly along the direction of motion of the moving end of the push-pull drive 4.

The analysis module can intercept and analyze the thrust force data when the slider reaches the highest point of the chute and when it reaches the end of the chute. The control system also includes a controller, which controls the push-pull drive device 4 to stop working according to the slider reaching the end of the chute signal detected by the slider in-position sensor 15. The position of the slider in the chute is detected by the high position sensor 17 and the slider in-position sensor 15, which facilitates the control system to obtain the force value when the slider reaches different points in the chute, realizes accurate grasp of the push-pull force value of the key point, avoids misjudgment, and can timely control the push-pull drive device 4 to stop when the slider reaches the end of the chute to prevent the slider from sliding out of the chute.

[0032] One end of the measuring platform is also provided with a limit block 18 that can be raised and lowered. When the limit block 18 rises, it can prevent the slider from sliding to the end of the chute and continuing to slide forward. A limit block lifting drive device 19 is also fixed to one end of the measuring platform. The limit block lifting drive device drives the limit block 18 to move up and down. The slider position sensor 15 is installed on the limit block 18. When the automobile sunroof mechanical assembly 1 is installed on the mechanical assembly positioning device 5, the limit block 18 rises to block the end of the chute, preventing the slider from sliding.

[0033] The mechanical component positioning device 5 includes a fixed seat 51, an upper pressure block 52, an upper clamping drive device, a lateral pressure block 54 and a lateral pressure drive device 55. The fixed seat is fixed with a limit retaining wall 511 extending in the vertical direction. The mechanical component can be placed flat on the fixed seat. The vertical side surfaces around the mechanical component are respectively stopped on each limit retaining wall 511. The lateral pressure block 54 can be installed on one side of the fixed seat 51 and can move in the horizontal direction. The lateral pressure drive device 55 can drive the lateral pressure block 54 to press the plane of the slide groove of the mechanical component. The upper clamping drive device can drive the upper pressure block 52 to move downward to press the upper side of the mechanical component so that the mechanical component is fixedly positioned on the fixed seat 51. The automobile sunroof mechanical component 1 is supported by the fixing seat on the fixing seat 51, and is initially limited by the limiting retaining wall 511, and then its lateral position is pressed and positioned by the lateral clamping block 54, thereby ensuring that the sliding path of the slider in the slide groove and the push-pull path of the push-pull rod 2 are on the same vertical plane, ensuring the accuracy of the detection data, and clamping the upper side of the automobile sunroof mechanical component 1 by the upper pressure block 52 to achieve high-precision fixed positioning of the automobile sunroof mechanical component 1. The mechanical component positioning device 5 is also preferably provided with a height adjustment structure and a horizontal position adjustment mechanism to adjust the positioning height of the automobile sunroof mechanical component 1, and ensure that its slide groove and push-pull force are in the same direction to ensure accurate detection.

[0034] The upper clamping drive device includes a lifting cylinder 53 and a lever mechanism 531. The lifting cylinder 53 and the lever mechanism 531 are installed on one end of the measuring platform. The upper pressure block 52 is fixedly installed on one end of the lever of the lever mechanism 531. The piston rod of the lifting cylinder 53 is hinged to the other end of the lever of the lever mechanism 531. The piston rod of the lifting cylinder 53 extends upward to drive the lever to rotate around its fulcrum, thereby forcing the upper and lower pressure blocks to descend and clamp the upper side of the mechanical component.

[0035] A lever swing angle limiting support 532 is also provided on one end of the measuring platform. This support 532 abuts against the underside of one end of the lever. As the lever swings downward until the upper pressure block 52 presses against the mechanical assembly, the underside of the lever abuts against the support 532. The support 532 limits the swing angle of the lever, and thus the downward pressure height of the upper pressure block 52, preventing damage to the sunroof mechanical assembly 1.
