[0002] The steering yoke, also known as the "ram's horn", is one of the important parts located on the front axle of the car. Its main function is to transmit and bear the load on the front of the car, while supporting and driving the front wheels to rotate around the kingpin to realize the steering function of the car.

[0003] The steering yoke spline phase angle refers to the angle set in a double-cross universal joint transmission system to achieve constant speed transmission or minimize speed and torque fluctuations. Generally, after the steering yoke is manufactured, it needs to be tested using a testing fixture. There are many types of such testing fixtures. For example, Chinese patent CN216845969U discloses a steering yoke spline phase angle testing fixture, which includes a base plate and other structures. This fixture can limit the operation of steering knuckles of different sizes. However, the existing testing fixtures on the market still have the defect of not being able to automatically detect. Because traditional testing fixtures are required to be manually operated, it not only consumes labor costs but also has low detection efficiency. Therefore, a steering yoke spline phase angle testing fixture is proposed to solve this problem. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-2In order to achieve the above-mentioned automatic detection purpose, the utility model provides the following technical solution: a steering yoke spline phase angle gauge, comprising a base 1, a gauge frame 2 is fixedly connected to the upper surface of the base 1, a socket 3 is fixedly connected to the bottom wall inside the gauge frame 2, a yoke body 4 is plugged into the top of the socket 3, a plug-in slot is provided at the top of the socket 3, a plug-in column is integrally formed at the bottom of the yoke body 4, the plug-in column is adapted to the plug-in slot, a side frame 5 is fixedly connected to the right side of the socket 3, and the bottom of the side frame 5 is fixedly connected to the base 1.

[0024] In order to achieve the purpose of automated inspection, the right inner wall of the side frame 5 is fixedly connected to an automatic inspection component with one end passing through the inspection frame 2 and the yoke body 4 in sequence and extending to the left inner wall of the inspection frame 2.

[0025] In the above embodiment, by providing an automatic inspection component, it is possible to automatically detect whether the yoke meets the production specifications, thereby saving labor costs.

[0026] Among them, the automatic inspection component includes an electric push rod 6, which is fixedly connected to the right wall surface inside the side frame 5, and the output end of the electric push rod 5 is fixedly connected to a connecting piece 7. The automatic inspection component also includes a pushing rod 8, the right side of the pushing rod 8 is fixedly connected to the connecting piece 7, the left side of the pushing rod 8 passes through the inspection frame 2 and the yoke body 4 and extends to the left side of the yoke body 4, the left side of the pushing rod 8 is fixedly connected to a pressure sensor 9, and the left side of the pressure sensor 9 is fixedly connected to a short through rod 10 with one end extending to the left wall surface inside the inspection frame 2. The right side wall inside the inspection frame 2 is provided with a receiving groove, which is adapted to the short through rod 10.

[0027] In this embodiment, the electric push rod 5 and the pressure sensor 9 are both existing equipment and can be directly purchased and used.

[0028] Among them, the top of the side frame 5 is fixedly connected with an inductive alarm 11, and the pressure sensor 9 is signal-connected to the inductive alarm 11. By setting the inductive alarm, an alarm can be immediately issued after the pressure cannot be flexibly generated.

When the short rod 10 can flexibly pass through the yoke body 4, it means that the spline angle is qualified. When the short rod 10 cannot flexibly pass through the yoke body 4, the pressure sensor 9 will sense the pressure and transmit the signal to the sensing alarm 11 to sound an alarm. The staff can immediately identify the yoke with an unqualified spline angle.
