Embodiment 1

[0033] refer to Figure 1-6 , a detection device for steering wheel flatness and coaxiality, including a load-bearing box 1, the load-bearing box 1 is set to a cylindrical shape, and the top of the load-bearing box 1 is provided with a sliding groove 6, and the sliding groove 6 is arranged to be connected with the load-bearing box 1 The same circular center, the bottom inner wall of the sliding groove 6 is provided with an electric slide rail 5, and the inner wall of the electric slide rail 5 is slidably connected with a mounting block 10, and the top of the mounting block 10 has a circular groove, and the circular groove The inner wall of the bottom of the bottom is connected with the adjusting tube 23 by bolts, and the outer wall of the adjusting tube 23 has symmetrically distributed Pie-shaped grooves 24, the bottom inner wall of the adjusting tube 23 is welded with a spring 26, and the top of the spring 26 is welded with a spring plate 25, and The outer wall of the spring ...

Embodiment 2

[0037] refer to Figure 7 , a detection device for steering wheel flatness and coaxiality. Compared with Embodiment 1, this embodiment has a through hole at the center of the shade cover 4, and the inner wall of the through hole is connected with a fan 27 by bolts, and the through hole A shading screen is arranged at one end of the shading screen, and a plurality of ventilation holes are opened on the shading screen.

[0038] Working principle: When in use, turn the steering wheel 3 upside down and put it on the concentric shaft 8. Since the concentric shaft 8 is located on the center of the load-bearing box 1, when the steering wheel 3 is installed, it shares the same center of circle with the load-bearing box 1. On the steering wheel 3 After installation, the ring frame is in contact with the top of the load-bearing box 1. If the flatness of the steering wheel 3 is qualified, then the ring frame will fit the top of the load-bearing box 1, and the laser cannot pass through. W...

Abstract

The invention discloses a device for detecting flatness and coaxiality of a steering wheel. The device comprises a bearing box, wherein the bearing box is set to be cylindrical; a sliding groove is formed in the top part of the bearing box; the sliding groove is set to be a circle with the same circle center as the bearing box; an electric sliding rail is arranged on the inner wall of the bottom part of the sliding groove; a mounting block is slidably connected to the inner wall of the electric sliding rail; a circular groove is formed in the top part of the mounting block; an adjusting pipe is fixedly connected to the inner wall of the bottom part of the circular groove; left-falling-shaped grooves are symmetrically formed in the outer wall of the adjusting pipe; and a spring is fixedly connected to the inner wall of the bottom part of the adjusting pipe. The device detects the flatness of the steering wheel by using laser, is rapid and accurate, and can avoid errors caused by unevenmass distribution during steering wheel manufacturing; all components of the detection mechanism measure the coaxiality of the steering wheel, and a U-shaped sleeve can be hidden in a storage groove according to needs by means of rapid coaxiality detection of the concentric circles and cooperation between the left-falling-shaped grooves and limiting blocks.

Description

technical field [0001] The invention relates to the technical field of steering wheel detection, in particular to a detection device for steering wheel flatness and coaxiality. Background technique [0002] A wheel-shaped device for controlling the direction of travel of automobiles, ships, and airplanes. Its function is to convert the force exerted by the driver on the edge of the steering wheel into torque and transmit it to the steering shaft. [0003] As an important device in the form of manipulation, there are two important parameters that can directly affect the overall performance of the steering wheel. One is the flatness of the steering wheel itself. If the edge of the steering wheel does not have a good flatness, the control and steering accuracy of the entire car will be greater. influences. Another important parameter is the coaxiality between the steering wheel and the steering shaft. Since the steering wheel and the steering shaft are connected by splines, i...
