The middle end of the rubber plate 2 and the middle end of the limit installation component 7 are on the same vertical line, which facilitates the control of the movement of the detection needle mechanism 5 by the robotic arm 4 to adapt to different automobile steering gear clearance detection;

[0029] As a further implementation of this solution, the number of multi-arm assemblies 6 corresponds to the number of limit mounting assemblies 7, and the number of multi-arm assemblies 6 is three. The rear end of the large arm 61 is fixedly connected to the front end of the vertical plate frame 3, thereby forming a triangular fixing mechanism for the vehicle steering gear, preventing the vehicle steering gear from moving, while not hindering the normal operation of the vehicle steering gear.

The ball block 71 and the second protrusion 72 fixed on one side of the small arm 66 rotate inside the ball groove 65 opened on the inner side of the front end of the big arm 61. When the angle adjustment of the small arm 66 is completed, start the electric telescopic rod 63, and the electric telescopic rod 63 drives the column slider 64 fixed on one side to move, and the column slider 64 drives the first protrusion 68 to move. When the first protrusion 68 is engaged with the second protrusion 72 at the rear end of the small arm 66, the angle of the small arm 66 is fixed. Adjust the angle of the limit mounting assembly 7 in the same way.

Start the hydraulic rod 77. The hydraulic rod 77 drives the fixed one side When the second connecting seat 79 moves, the second connecting seat 79 squeezes the limiting telescopic rod 78, and the limiting telescopic rod 78 contracts. The limiting telescopic rod 78 can improve the stability of the movement of the second connecting seat 79 and at the same time start the supporting function of the second connecting seat 79. When the second connecting seat 79 moves, it drives the arc clamping plate 75 on the second connecting seat 79 to move. When the steel balls 76 inside the same group contact the pull rod, the pull rod is now between the two arc clamping plates 75. At this time, the limit of the pull rod is completed. Based on the same principle, the multi-arm assembly 6 and the limiting mounting assembly 7 at the upper end are adjusted, and the limiting mounting assembly 7 at the upper end is used to limit the shaft of the steering gear of the automobile. After the installation is completed, a triangle is formed at the fixed part of the automobile steering gear. At this time, the automobile steering gear cannot move. When detecting the gap of the automobile steering gear, the steering shaft of the automobile steering gear can be rotated to control the movement of the pull rod of the automobile steering gear. The detection needle mechanism 5 is driven by the mechanical arm 4 to adjust the position, and the clearance of the automobile steering gear is detected by the detection needle mechanism 5, thereby achieving the detection effect.
