The sleeve is provided with a lock nut 302, and the lock nut 302 is used for fixedly connecting the sleeve and the movable rod.
The telescopic rod 301 can be telescopic to adapt to the leaf springs 200 with different lengths, after the length of the movable rod extending out of the sleeve is adjusted according to the leaf springs 200, the lock nut 302 is screwed down, so that the movable rod is not moved any more, the value of the second scale line can detect whether the extending lengths of the two movable rods are identical, and therefore the fact that in an initial state, when the motor 107 is not started, the leaf springs 200 are arranged in the middle is guaranteed.
In this embodiment, each detection mechanism further comprises a counter for recording the angle between the reference line and the reading line and the value of the first scale line.
The working process comprises the following steps: the leaf spring 200 is placed centrally between the clamp plate 101 and the movable plate 108 on the rear side, and the clamp rotation bolt 102 is rotated to drive the movable plate 108 to move in the direction approaching the leaf spring 200, thereby clamping the leaf spring 200.

A detection mechanism is first mounted on the bracket 100. The motor connection block 330 is fixedly connected to the upper side of the motor case 106 at the same side by screws. The output shaft of the motor 107 is inserted into the motor connecting hole 3311, the clamping block is arranged in the clamping groove, and the trunnion line positioning assembly is arranged in the reel on the same side, at this time, the ball joint block 320 is positioned in the reel, and the adapting extension rod 321 abuts against the inner peripheral wall of the reel. Then, another detecting mechanism is also installed on the bracket 100, the lengths of the movable bars at the left and right sides are adjusted, and then the two telescopic bars 301 are connected through the transparent plate 312.
After the installation is completed, the ball joint block 320 is adjusted to the lowest side of the reel, the counter is started at the moment, then the motor 107 is started, the motor 107 drives the screw 331 to synchronously rotate, the screw 331 drives the ball head 322 to rotate when rotating, the ball head 322 gradually moves upwards, and the ball joint block 320 and the vertical rod 340 are further driven to gradually move upwards.
After two trunnion line locating components are arranged in two winding ears, because the telescopic rod 301 is perpendicular to the vertical rod 340, when the telescopic rod 301 is inclined relative to the horizontal plane due to the driving of the vertical rod 340, an included angle is formed between the datum line and the reading line, the angle is recorded by the angle sensor, and the angle reflects the levelness of the winding ears. Because the vertical swinging rod 303 is always vertical to the ground, when the vertical swinging rod 303 and the vertical rod 340 are not parallel, the connecting pipe 305 and the indicating rod 304 relatively move, the value of the first scale line changes, and the value of the first scale line reflects the verticality of the winding lug.
During detection, the counter records the angle between the datum line and the reading line and the value of the first scale line at the moment, and the fitting line is formed on the coordinate system by taking the angle as the X axis and the value of the first scale line as the Y value.
In an ideal state, when the central axis of the coiled lug is vertical to a horizontal plane and the central axis is parallel to a plane vertical to the ground, a fitting curve formed by the angle and the numerical value of the first scale line on the coordinate graph is a straight line inclined at a zero crossing point, and the straight line is set as a standard fitting line.
Because the inner peripheral wall of the rolling lug is uneven, the lengths of the plurality of adapting extending rods 321 extending out of the second mounting channel are different, so that the vertical rods 340 incline, a wavy curve is formed by a plurality of angles and the numerical value of the first scale line on a coordinate system during measurement, a fitting range interval is set, including the maximum value and the minimum value of the fitting range interval, and when the fitting range interval is exceeded, the rolling lug is unqualified.
The number of contact surfaces between the winding lug and a connecting shaft which is fixedly connected with the winding lug can be judged according to the maximum value and the minimum value of the curve, when the concave and convex parts of the inner peripheral wall of the winding lug are smaller, the convex parts which are in contact with the connecting shaft are more, and when the convex parts of the inner peripheral wall of the winding lug are larger, the convex parts which are in contact with the connecting shaft are fewer, so that whether the supporting strength of the winding lug is enough is judged. When the measured curve is in the fitting range interval, but the contact surface of the winding lug and the connecting shaft is too small, the supporting strength of the winding lug is unqualified, and the winding lug is unqualified.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
