An automatic testing table for the strength of a steering column Technical Field

[0001] This utility model relates to the field of steering column strength testing technology, and in particular to an automatic steering column strength testing platform. Background Technology

[0002] The automatic steering column strength testing bench is a professional device used in the automotive manufacturing and related parts testing fields to accurately evaluate the strength performance of the steering column. It tests whether the steering column meets the design strength standards by simulating various mechanical conditions that the steering column is subjected to during actual vehicle operation, such as static pressure, dynamic loading, and fatigue stress.

[0003] Existing steering column strength testing methods have some shortcomings. Traditional methods cannot fix steering columns of different models and specifications before strength testing, often requiring changes to testing fixtures and adjustments to the testing process. This is cumbersome and costly, reducing the applicability of the testing station. To address these issues, an automatic steering column strength testing station has been proposed for improvement and upgrading. Summary of the Invention

The upper ends of the threaded rods are connected to servo motors inside the positioning frames, and a testing cylinder is provided on the front side of the positioning frames.

[0006] Two positioning structures are fixedly installed on the other side of the upper end of the testing machine platform.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As shown in Figures 1 to 4, this embodiment provides an automatic testing platform for the strength of a steering column, including a testing platform 1. Two positioning frames 2 are fixedly installed on one side of the upper end face of the testing platform 1, and threaded rods 22 are rotatably installed inside each positioning frame 2. The upper end of each threaded rod 22 is connected to a servo motor inside the positioning frame 2. A testing cylinder 21 is provided on the front side of the positioning frame 2.

[0023] Two positioning structures 4 are fixedly installed on the other side of the upper end of the testing machine 1. The two positioning structures 4 include mounting bases 41 fixedly installed on the upper end of the testing machine 1. A drive motor 42 is fixedly installed inside each of the two mounting bases 41, and a bidirectional lead screw 43 is fixedly connected to the output end of each drive motor 42. Two connecting cylinders 45 are symmetrically threaded to the outer wall of the bidirectional lead screw 43, and a placement frame 44 is fixedly connected to the upper end of the connecting cylinder 45. Electric push rods 47 are symmetrically arranged on the outer side of the placement frame 44, and an anti-slip clamp 48 is fixedly connected to one end of the electric push rod 47. A steering column body 3 is installed inside the placement frame 44.

[0024] As shown in Figure 3, the mounting base 41 has an installation groove inside, and the bidirectional lead screw 43 is rotatably installed inside the installation groove. The bottoms of the two placement brackets 44 are slidably connected to the upper end of the mounting base 41. The two placement brackets 44 are the same size. The two sides of the outer wall of the placement bracket 44 are fixedly connected to the hinge seat 46. The hinge seat 46 is fixedly installed with an electric push rod 47 inside. One end of the electric push rod 47 passes through the inside of the placement bracket 44 and the extended end is fixedly connected to the anti-slip plate 48. The two sets of anti-slip plates 48 are the same size and are adapted to the steering column body 3.

[0025] The drive motor 42 drives the bidirectional lead screw 43 to rotate within the mounting base 41, causing the two connecting cylinders 45 to move relative to each other and place steering columns of different lengths. When the two placement racks 44 move to the appropriate distance, they stop. Then, the external power supply is connected, and the electric push rods 47 on both sides of the two sets of placement racks 44 are driven to work, causing the electric push rods 47 to move relative to each other and clamp and position the steering column. This can limit the movement of steering columns of different diameters.

[0026] As shown in Figure 4, the outer wall of the threaded rod 22 is threadedly connected to the mounting plate 23, the detection cylinder 21 is fixedly mounted on the mounting plate 23, the two ends of the rear side of the mounting plate 23 are slidably connected to the positioning frame 2, one end of the detection cylinder 21 is connected to the steering column body 3, and a control knob is provided on the front side of the detection machine 1.

[0027] The servo motor on the drive positioning frame 2 drives the threaded rod 22 to rotate, which in turn drives the detection cylinder 21 on the mounting plate 23 to adjust its height. This facilitates the strength testing of steering columns at different heights and meets the strength testing requirements of steering columns of different specifications.

[0028] The working principle and process of this utility model are as follows: When strength testing of the steering column is required, the operator first passes the two steering columns through the two sets of placement brackets 44. According to the length of the steering column, the drive motor 42 drives the double-acting screw 43 to rotate within the mounting base 41, causing the placement brackets 44 on the two connecting cylinders 45 to move relative to each other to place steering columns of different lengths. When the two placement brackets 44 move to the appropriate distance, they stop. Then, the external power supply is connected, and the electric push rods 47 on both sides of the two sets of placement brackets 44 are driven to work, causing the electric push rods 47 to move... The anti-slip clamp 48 moves relative to the steering column to clamp and position it, which can limit the steering column of different diameters and improve the applicability of the test bench to the steering column. After the steering column is fixed, one end of the test cylinder 21 is connected to the steering column. After the connection is made, the pressure strength test of the steering column begins. The test data is displayed on the screen. At the same time, the servo motor on the positioning frame 2 drives the threaded rod 22 to rotate, which causes the threaded rod 22 to drive the test cylinder 21 on the mounting plate 23 to adjust the height, so as to adapt to the strength test of steering columns of different heights.
