Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steering column testing technology, specifically relating to a steering column testing device. Background Technology
[0002] The steering column is a key component of the car's steering system. It is a mechanical transmission element that connects the steering wheel and the steering gear, responsible for translating the driver's operation of the steering wheel into the action of the steering gear, thereby controlling the vehicle's direction of travel. It is usually located between the driver's seat and the steering wheel, with one end connected to the steering wheel and the other end connected to the steering gear (such as a rack and pinion mechanism) via a drive shaft. The steering column needs to undergo quality inspection during the production of automobiles to ensure the safety of the vehicle.
[0003] The prior art utility model patent with authorization announcement number CN 217654927U proposes a quality inspection device for automobile steering column production. This device places the steering column in a fixed sleeve, secures it with fixing bolts, and then clamps and holds the steering column in place using a connecting plate, threaded post, and clamping plate. Starting a motor drives a torque sensor to rotate the connecting shaft, causing the fixed sleeve to apply torque to the steering column. The torque sensor, in conjunction with an overload device, detects the torque of the steering column. This achieves the goal of easily detecting the torque of the automobile steering column using a torque detection device, avoiding the situation where traditional quality inspections for automobile steering column production mostly focus on testing the strength of the steering column.
[0004] However, in actual use, this device can only detect the torque of the steering column, making it inconvenient to test the hardness of the device itself. This reduces the device's applicability and flexibility. In addition, the device lacks a protective structure during use, which can easily cause steering columns with insufficient torque to fly out of the device, posing a threat to the health of the workers. Therefore, we need to upgrade and modify the existing technology. Utility Model Content

[0024] 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.
[0025] like Figure 1As shown in Figure 5, this embodiment provides a steering column testing device, including a device body 1. The device body 1 includes a workbench 2 and a mounting base 17. A motor 5, a mounting frame 8, and a support frame 12 are provided above the workbench 2. One end of the motor 5 is connected to a torque sensor 6, and the other end of the torque sensor 6 is connected to a fixing sleeve 7. A connecting seat 9 is installed on the inner wall of the mounting frame 8. A pressure gauge 13 is connected below the support frame 12, and a pressure head 14 is connected below the pressure gauge 13. A placement plate 15 is provided below the pressure head 14, and a cylinder 16 is connected below the placement plate 15. A protective cover 18 is installed on the mounting base 17, and a cover plate 20 is provided inside the protective cover 18. Both ends of the cover plate 20 are connected to a rotating shaft 21. One end of the rotating shaft 21 is connected to a connecting shaft 22, and one end of the connecting shaft 22 is connected to a worm gear 23. A worm 24 meshes below the worm gear 23, and one end of the worm 24 is connected to a motor 25.
[0026] Preferably, the workbench 2 is equipped with cabinet doors 3, and multiple sets of cabinet doors 3 are provided. Each set of cabinet doors 3 is fixedly equipped with a handle 4. By providing cabinet doors 3, items placed in the workbench 2 can be stored and protected. By providing handles 4, users can easily open and close the cabinet doors 3, which increases the practicality and convenience of the device. Bolts 11 are screwed into the connecting seat 9. Two sets of bolts 11 are symmetrically provided. One end of each set of bolts 11 is fixedly connected to a clamping plate 10. By providing clamping plates 10, the device can be clamped. By providing bolts 11, users can easily adjust the pre-tightening of clamping plates 10.
[0027] Preferably, the protective cover 18 has a movable hole 19, and a rotating shaft 21 is rotatably installed in the movable hole 19. By setting the movable hole 19 and the rotating shaft 21, the closeness and connection between the devices are increased, making it convenient for the user to rotate and adjust the devices. A fixing bracket 26 is installed on the worm gear 24. The fixing bracket 26 is located on one side of the protective cover 18 and is fixedly connected to the protective cover 18. By setting the fixing bracket 26, the safety of the worm gear 24 during use is ensured. A support plate 27 is fixedly connected to one side of the fixing bracket 26. A second motor 25 is fixedly installed on the top of the support plate 27. By setting the support plate 27, the stability of the second motor 25 is increased, ensuring the safety of the second motor 25 during operation.
[0028] The working principle and process of this utility model are as follows: During use, motor 25 is controlled to run, driving worm gear 24 to rotate. This rotation drives worm wheel 23, which in turn drives connecting shaft 22. The rotating shaft 22 then drives rotating shaft 21, which in turn drives cover plate 20. This continues until cover plate 20 reaches the appropriate position. The steering column to be tested is then placed in the fixing sleeve 7 and fixed. Bolt 11 is then rotated, pushing clamping plate 10 to hold and fix the steering column. After fixing, cover plate 20 is reset, and motor 5 is started, causing its output end to rotate. This drives torque sensor 6, which in turn drives fixing sleeve 7 to rotate, thus affecting the steering column. Torque is applied, and the torque sensor 6 detects the torque on the steering column. When the steering column needs to be tested for hardness, the user places the steering column on the placement plate 15, adjusts the pressure gauge 13 to the specified measurement value, and controls the cylinder 16 to push the placement plate 15 and the steering column upward until they are below the pressure head 14. The pressure head 14 tests the hardness of the steering column until the test is completed. This hardness test of the steering column ensures that the steering column meets the mechanical performance requirements of the design, improves product quality, reduces rework rate and scrap loss, avoids the risk of breakage or deformation due to material defects, and also protects the staff, reducing the risk of accidental contact or injury from flying debris. This improves the safety of the device and facilitates the handling of the parts being tested.
