The first connecting rod 654, the second connecting rod 655 and the third connecting rod 656 respectively drive the first sliding block 657, the second sliding block 658 and the third sliding block 659 in the first slide groove 6511, the second slide groove 6512 and the second slide groove 6512. Move in the three chute 6513. When respectively along the outer contour edge positions of the first chute 6511, the second chute 6512 and the third chute 6513, the first slider 657, the second slider 658 and the third slider 659 are respectively connected with the U-shaped parts The inner wall abuts and continues to slide outwards to squeeze the inner side of the U-shaped part, thereby realizing the clamping and limiting of the U-shaped part. In order to achieve a better clamping and limiting effect, the first slider 657 and The abutment position of the third sliding block 659 against the inner wall of the U-shaped product is set near the position where the first clamping member 3 clamps the U-shaped product. The abutting position of the second slider 658 against the inner wall of the U-shaped part is set near the position where the upper detection assembly 5 abuts against the U-shaped part. The inner and outer sides are clamped together, and the first clamping part 3, the second clamping part 4 and the third clamping part 6 exert a fixed clamping force on the U-shaped part to strengthen the clamping of the U-shaped part. hold effect.

A limiting plate 6592 is set on the vertical plate 651, and the limiting plate 6592 is used to prevent the connecting rod from coming out of the chute, and the limiting plate 6592 is set at the first chute 6511, the second chute 6512 and the third chute 6513 , The side wall of the limiting plate 6592 in contact with the vertical plate is provided with a guide column, and the guide column extends into the chute.

Specifically, when the U-shaped workpiece is subjected to profile detection and machine trimming, the first clamping part 3 and the second clamping part 4 are clamped to the U-shaped workpiece, and the first clamping part 3 and the The second clamping members 4 each include an elastic member, which can be a spring 6591 or an elastic rubber member, and different elastic members can be selected according to the specific structure. Thus, the clamping force output by the first clamping member 3 and the second clamping member 4 on the U-shaped workpiece is fixed. Now turn the handle 61, the handle 61 drives the second connecting piece 62, the second connecting piece 62 drives the turntable 652 to rotate, and the turntable 652 drives the connecting rod to move, and then drives the slider to move in the chute. After the slider abuts against the inner sidewall of the U-shaped part, the handle 61 is continued to be rotated at this time, so that the slider has a movement tendency to further press the inner sidewall of the U-shaped part. Since the slider is provided with a spring 6591, within the range not exceeding the effective stroke of the spring 6591, the output clamping force of the slider on the U-shaped workpiece is the elastic force of the spring 6591. According to Hooke's law, the elastic force output by the spring 6591 at this time is related to the elastic coefficient of the spring 6591 itself and the stroke of the spring 6591 . The elastic coefficient of the spring 6591 is determined according to the characteristics of the spring 6591 and is fixed. The stroke of the spring 6591 can be calculated through the crank slider structure composed of the turntable 652, the connecting rod and the slider.

It should be pointed out that Hooke's law is the prior art in this field, and the calculation method of the specific elastic force will not be described here. According to the rotation angle of the turntable 652, combined with the crank-slider structure composed of the turntable 652, the connecting rod and the slider, calculating the movement length of the slider is a prior art in the art, so it will not be described here. In this embodiment, the moving length of the slider is equal to the stroke of the spring 6591 . Therefore, the elastic force output by the spring 6591 can be obtained through the rotation angle of the turntable 652 , and the elastic force output by the spring 6591 corresponding to different rotation angles of the turntable 652 can be reflected through the dial 64 .

In addition, the setting of the spring 6591 can also prevent the slider from directly acting on the U-shaped workpiece to cause deformation of the U-shaped workpiece.

Furthermore, U-shaped workpieces are thin-walled and large-sized workpieces. If the U-shaped workpieces are not properly clamped and limited when the surface accuracy of the U-shaped workpieces is tested, inaccurate measurements will easily occur. The clamping force is too small to effectively clamp and limit the U-shaped parts. The clamping force is too large, and the U-shaped workpiece will be deformed under the action of the clamping force. In this embodiment, both the first clamping part 3 and the second clamping part 4 output a fixed clamping force, and the clamping force output by the third clamping part 6 can be 5N, 10N, 15N, 20N, 25N, 30N, 35N, 40N, 45N, 50N, 55N and 60N, preferably 45N. The first clamping part 3 and the second clamping part 4 are set to output a fixed clamping force, and the clamping force output by the third clamping part 6 is adjustable. While reducing the complexity of clamping force adjustment, the clamping force for U-shaped workpieces can be kept within a reasonable range. Improve the accuracy of surface precision detection of U-shaped parts.
