Technical Field

[0001] This utility model belongs to the field of tooling, specifically relating to a universal fixing tooling for steering systems. Background Technology

[0002] Throughout the entire lifecycle of automobile research and development, production, and after-sales service, testing and verifying the steering system is a core aspect of ensuring vehicle safety and performance reliability. Its fundamental purpose is to identify potential risks in advance, ensure the steering system always meets design requirements, and prevent safety accidents or performance degradation caused by steering system failure.

[0003] Given the differences in steering systems from different brands and manufacturers, and the wide variety of steering systems on the market, different fixed positions and actual vehicle angles require different fixtures. This increases the variety of fixtures used in the testing and verification of steering systems, making it extremely time-consuming and material-intensive. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by providing a universal fixing fixture for steering systems. This universal fixing fixture can be matched and connected to different types of steering systems through the universal adjustment of the fixing clamp, connecting fixing clamp and Z-axis fixing clamp, and can be used with various test benches.

[0005] To achieve the above objectives, this utility model provides a universal fixing fixture for a steering system, including a chassis, a main support column on the chassis, a Z-axis fixing clamp on the main support column that can rotate and move in the Z-axis direction relative to the main support column, a first auxiliary rod on the Z-axis fixing clamp, a fixing clamp assembly on the first auxiliary rod that can move and rotate along its axial direction, the fixing clamp assembly including a fixing clamp that can move and rotate along the first auxiliary rod, a second auxiliary rod perpendicularly connected to the first auxiliary rod on the fixing clamp, a connecting fixing clamp on the second auxiliary rod that can move and rotate along its axial direction, and a plurality of connecting holes on the connecting fixing clamp.

[0006] As a further optimization, the Z-axis fixing clamp includes a Z-axis fixing clamp body. One end of the Z-axis fixing clamp body has an inwardly inclined first slope on both sides. The ends of the two first slopes away from the Z-axis fixing clamp body have two outwardly extending first clamping arms. The middle part of the Z-axis fixing clamp body has a first clamping groove that communicates with the gap between the two first clamping arms. The first clamping arms have first threaded holes.

[0007] As a further optimization, the fixing clamp includes a fixing clamp body, one end of which has two outwardly extending second clamping arms on opposite sides, the middle of the fixing clamp body has a second clamping groove communicating with the gap between the two second clamping arms, and the second clamping arms have second threaded holes.

[0008] As a further optimization, the connecting clamp includes a connecting clamp body, one end of which has an inwardly inclined second slope on both sides, and the ends of the two second slopes away from the connecting clamp body have two outwardly extending third clamping arms. The middle part of the connecting clamp body has a third clamping groove that communicates with the gap between the two third clamping arms. The third clamping arms have third threaded holes, and the connecting clamp body has multiple connecting holes.

[0009] Advantages and beneficial effects of this utility model

[0010] 1. This utility model allows the Z-axis fixing clamp to rotate axially and move Z-axis around the main support through the cooperation of the Z-axis fixing clamp and the main support. The fixing clamp can rotate axially and move around the first auxiliary rod through the cooperation of the first auxiliary rod and the fixing clamp. Since the fixing clamp is set perpendicular to the second auxiliary rod, the connecting fixing clamp can rotate axially and move around the second auxiliary rod through the cooperation of the second auxiliary rod and the connecting fixing clamp. In this way, universal adjustment can be performed according to different types of steering systems, so that the fixed position and actual vehicle angle of the steering system can be guaranteed, and the connection and fixing requirements during the test and verification of different types of steering systems can be met.

[0011] 2. This utility model extends the connecting and fixing clamp and provides multiple connecting holes on it. These connecting holes can be used to install flanges, brackets, and other tools to connect different types of steering systems, ensuring the flexible use of the universal fixing fixture.

[0012] 3. While ensuring compatibility with different types of steering systems, this utility model also greatly guarantees the rigidity requirements of the universal fixing fixture. On the one hand, the universal fixing fixture is made of high-hardness materials such as No. 45 steel. On the other hand, the three fixing clamps are all clamped and fixed by bolts, thus ensuring the fixing strength and rigidity requirements of the fixing clamps. This significantly reduces the impact of noise and vibration generated by the steering system during operation on the universal fixing fixture during testing and verification, and reduces the degree of vibration and shaking of the fixing fixture during testing and verification.

[0013] 4. This utility model has a simple structure, low maintenance requirements, and high environmental adaptability. Moreover, the surface has been treated with black oxidation, which can be used with various test benches to conduct tests and verifications in various temperature environments.

[0018] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein.

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the early stages of research and development, this application attempted to install three slide rails for movement in the XYZ directions to test and verify connections with different types of steering systems. However, since the steering system generates vibration and noise during operation, this vibration is transmitted to the slide rails. The addition of slide rails alters the transmission path of the fixed fixture, creating a "stiffness bottleneck" at the connection point between the slide rail and the fixed fixture, and between the slider and the slide rail. This amplifies the vibration transmission, causing the fixed fixture to vibrate or sway more. The vibration or sway of the fixed fixture is directly superimposed on the test data, thus reducing the accuracy and effectiveness of the steering system test data. After continuous experimentation, this application selected a method using three fixed clamps in conjunction with the main support or auxiliary rod for multi-directional movement and rotation. This ensures compatibility with different steering systems while greatly guaranteeing the stiffness requirements of the universal fixed fixture, significantly reducing the impact of noise and vibration generated by the steering system during testing on the universal fixed fixture. The structure of the universal fixed fixture is described in detail below.

[0021] like Figure 1 As shown, a universal fixing fixture for a steering system includes a chassis 1, on which a main support column 2 is fixedly connected and perpendicularly arranged. The chassis 1 and the main support column 2 provide overall support for the universal fixing fixture. The main support column 2 is provided with a Z-axis fixing clamp 3 that can rotate and move Z-axis relative to the main support column 2. A first auxiliary rod 4 is integrally connected to one side of the Z-axis fixing clamp 3. The first auxiliary rod 4 is provided with a fixing clamp group 5 that can move and rotate along its axial direction. The fixing clamp group 5 includes a fixing clamp 6. The fixing clamp 6 can move and rotate along the first auxiliary rod 4. A second auxiliary rod 7 is integrally connected to one side of the fixing clamp 6. The second auxiliary rod 7 is provided with a connecting fixing clamp 8 that can move and rotate along its axial direction. The connecting fixing clamp 8 is provided with multiple connecting holes 9 for connecting flanges, brackets, and other tools. The steering system is connected to the universal fixing fixture through flanges, brackets, and other tools.

[0022] Since the Z-axis fixing clamp 3 can rotate axially around the main support 2, it will drive the first auxiliary rod 4 and the fixing clamp group 5 to rotate axially, thereby changing the angle and direction of the fixing clamp group 5. When the fixing clamp 6 is adjusted to the X-axis, it can move in the X-axis relative to the first auxiliary rod 4. Since the second auxiliary rod 7 is perpendicularly connected to the side surface of the fixing clamp 6, the connecting fixing clamp 8 can move in the Y-axis along the second auxiliary rod 7. Conversely, the fixing clamp 6 moves in the Y-axis relative to the first auxiliary rod 4, and the connecting fixing clamp 8 moves in the X-axis relative to the second auxiliary rod 7. Therefore, the direction of movement of the fixing clamp 6 and the connecting fixing clamp 8 will change with the rotation of the fixing clamp 3.

[0023] like Figure 2As shown, the Z-axis fixing clamp 3 includes a Z-axis fixing clamp body 31. The Z-axis fixing clamp body 31 has chamfered edges around its perimeter. One end of the Z-axis fixing clamp body 31 has inwardly inclined first slopes 32 on opposite sides. The ends of the first slopes 32 away from the Z-axis fixing clamp body 31 have two outwardly extending first clamping arms 33. A first auxiliary rod 4 is integrally connected to the side wall of the Z-axis fixing clamp 3 away from the first clamping arms 33. The middle part of the Z-axis fixing clamp body 31 has a connection with the two first clamping arms 33. The first clamping groove 34 is connected to the gap between the three. The Z-direction fixing clamp 3 is connected to the main support 2 through the first clamping groove 34. The first clamping arm 33 has a first threaded hole 35. The first inclined surface 32 on both sides will cause the first clamping arms 33 on both sides of the fixing clamp to have a certain deformation. When the bolt in the first threaded hole 35 is tightened, the preload generated will cause the first clamping arms 33 on both sides to deform. Therefore, it can generate a greater clamping force on the main support 2, making the Z-direction fixing clamp 3 more firmly fixed.

[0024] like Figure 2 As shown, the fixing clamp 6 includes a fixing clamp body 61 with chamfered edges around its perimeter. One end of the fixing clamp body 61 has two outwardly extending second clamping arms 62 on opposite sides. A second auxiliary rod 7 is integrally connected to the side wall of the fixing clamp body 61 away from the second clamping arms 62. The middle part of the fixing clamp body 61 has a second clamping groove 63 that communicates with the gap between the two second clamping arms 62. The fixing clamp 6 is connected to the first auxiliary rod 4 through the second clamping groove 63. The second clamping arms 62 have second threaded holes 64, and bolts are internally threaded into the second threaded holes 64. By tightening the bolts, the position and angle of the fixing clamp 6 can be fixed relative to the first auxiliary rod 4.

[0025] like Figure 2The connecting clamp 8 includes an elongated connecting clamp body 81. The connecting clamp body 81 has chamfered edges around its perimeter. One end of the connecting clamp body 81 has inwardly inclined second slopes 82 on both sides. The ends of the second slopes 82 away from the connecting clamp body 81 have two outwardly extending third clamping arms 83. The middle part of the connecting clamp body 81 has a third clamping groove 84 that communicates with the gap between the two third clamping arms 83. The connecting clamp 8 is connected to the second auxiliary rod 7 through the third clamping groove 84. The third clamping arms 83 have third threaded holes 85. The second slopes 82 on both sides will cause the third clamping arms 83 on both sides of the clamp to have a certain deformation. When the bolts set in the third threaded holes 85 are tightened, the preload generated will cause the third clamping arms 83 on both sides to deform, thus generating a greater clamping force on the second auxiliary rod 7, making the connecting clamp 8 more secure. The connecting and fixing clamp body 81 is extended and has multiple connecting holes 9. The connecting holes 9 can be used to install tools such as flanges and brackets to connect to different types of steering systems. Therefore, different tools can be replaced according to different types of steering systems, ensuring the flexible use of the universal fixing fixture.

[0026] To reduce the impact of the steering system on the universal fixture during testing and verification, this application employs bolt clamping on the three clamps. Due to the rigid connection of the bolts and the engagement of the bolts with the threads during tightening, the axial preload of the bolts is directly transmitted to the contact surface between the clamps and the mating main support or auxiliary rod. Therefore, the contact surface generates uniform and stable contact pressure, which maximizes the restriction of the relative position between the clamps and the main support or auxiliary rod, thereby improving the overall rigidity. At the same time, this application is made of high-hardness materials such as 45# steel, which can improve the overall rigidity of the universal fixture, significantly reducing the impact of the steering system on the universal fixture during testing and verification, and improving the accuracy and effectiveness of the steering system test data.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, and are not intended to limit them. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the present utility model.
