Description

Technical Field

[0001] This utility model relates to the field of steering system testing technology, specifically a general-purpose phase angle testing fixture for steering gears. Background Technology

[0002] In recent years, the development of steering gears has been driven by the need for higher efficiency, which has also led to demands for reducing errors and costs during the development, assembly, transportation, and trial production processes.

[0003] Phase angle is a key parameter for the coordination between the steering gear and the vehicle. It plays a crucial role when the steering gear is transported to the vehicle manufacturer for assembly. Therefore, controlling the steering gear phase angle is of paramount importance during the steering gear development process.

[0004] Currently, during the development phase of steering gears, a separate tooling for phase angle detection is designed for each individual project. However, with an increasing variety of vehicle models in the market, the number of phase angle detection tooling has also increased, leading to not only a waste of resources but also reduced development efficiency.

[0005] Therefore, it is necessary to design a universal phase angle detection fixture for steering gears to meet the phase angle detection needs of different steering gear models, thereby reducing development resources and improving development efficiency. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a universal phase angle detection fixture for steering gears to meet the phase angle detection needs of different steering gear models, thereby reducing development resources and improving development efficiency.

[0007] To achieve the above objectives, this utility model provides a universal phase angle detection fixture for steering gears, comprising an adjusting nut connecting mechanism, a connecting block, a moving rod, an extending rod, a connecting rod, and an interface detection mechanism. The bottom of the moving rod is fixed to the connecting block, and the adjusting nut connecting mechanism is rotatably connected to the connecting block. The axis of the adjusting nut connecting mechanism is perpendicular to the axis of the moving rod. One end of the extending rod is sleeved on the upper part of the moving rod, and one end of the connecting rod is sleeved outside the other end of the extending rod. The other end of the connecting rod is fixed to the interface detection mechanism, whose axis is perpendicular to the axis of the connecting rod. The interface detection mechanism includes a housing, a locking nut, and interface-shaped washers. At least one interface-shaped washer is disposed inside the housing and is fixed by the locking nut. The notch shape of one interface-shaped washer or the combined notch shape of two or more interface-shaped washers matches the shape of the input shaft interface of the steering gear.

[0008] The adjusting nut connecting mechanism is connected to the adjusting nut interface of the steering gear pressure block position, and the input shaft interface of the steering gear passes through the interface detection mechanism.

[0009] The input shaft interface includes a spline single-plane structure, a cylindrical double-plane structure, and a cylindrical V-shaped plane structure.

[0010] The interface shape gaskets include spline gaskets, single-plane gaskets, double-plane gaskets, and V-shaped gaskets.

[0011] The cylindrical end face of the adjusting nut connecting mechanism and the surface of the moving rod are provided with scales.

[0012] The connecting surface between the connecting block and the moving rod, and the connecting surface between the connecting rod and the interface detection mechanism, are both provided with square blocks with protrusions.

[0013] Compared with the prior art, this utility model adjusts the angle, length and size of the detection hole to adapt to the input shaft interface of different steering gear models, thereby achieving the purpose of phase angle detection, effectively reducing steering gear development resources and improving development efficiency.

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] See Figure 1 This utility model is a general-purpose phase angle detection fixture for steering gears, including an adjusting nut connecting mechanism, a connecting block, a moving rod, an extending rod, a connecting rod, and an interface detection mechanism. The bottom of the moving rod 3 is fixed with a connecting block 2, and the end of the connecting block 2 is equipped with an adjusting nut connecting mechanism 1. The adjusting nut connecting mechanism 1 is rotatably connected to the connecting block 2. The axis of the adjusting nut connecting mechanism 1 is perpendicular to the axis of the moving rod 3. One end of the extending rod 4 is sleeved on the upper part of the moving rod 3, and one end of the connecting rod 5 is sleeved on the other end of the extending rod 4. The other end of the connecting rod 5 is fixed with an interface detection mechanism 6, and the axis of the interface detection mechanism 6 is perpendicular to the axis of the connecting rod 5.

[0029] See Figure 2 The interface detection mechanism 6 includes a housing 61, a locking nut 62, and an interface shape gasket 63. At least one interface shape gasket 63 is disposed inside the housing 61 and is fixed by the locking nut 62. The notch shape of one interface shape gasket 63 or the combined notch shape of two or more interface shape gaskets 63 matches the shape of the input shaft interface 7 of the steering gear.

[0030] See Figures 11-13 The input shaft interface 7 of the existing steering gear includes a spline single-plane structure 71, a cylindrical double-plane structure 72, and a cylindrical V-shaped plane structure 73.

[0031] See Figures 3-6 To match the input shaft interface 7 of different steering gears, the interface shape shims 63 include spline shims 631, single-plane shims 632, double-plane shims 633, and V-shaped shims 634. By selecting different interface shape shims 63, the phase angle detection fixture can be matched to the phase angle detection requirements of various steering gears.

[0032] The notch edge of spline washer 631 has a spline structure, matching the spline portion of spline single-plane structure 71. The notch of single-plane washer 632 is a combination of a circle and a single plane, matching the single-plane portion of spline single-plane structure 71. After spline washer 631 and single-plane washer 632 are combined, the shape of their notch combination matches the shape of spline single-plane structure 71. Figure 8 As shown.

[0033] The notch of the double-plane gasket 633 is a combination of a circle and a double plane, which matches the shape of the cylindrical double-plane structure 72, such as... Figure 9 As shown.

[0034] The notch of the V-shaped gasket 634 is a combination of a circle and a V-shaped surface, which matches the shape of the cylindrical V-shaped plane structure 73, such as... Figure 10 As shown.

[0035] The cylindrical end face of the adjusting nut connecting mechanism 1 and the surface of the moving rod 3 are marked with scales. The scales of the adjusting nut connecting mechanism 1 facilitate reading the rotation angle of the moving rod 3 and confirming whether the measured angle of the steering gear housing meets the design requirements. The scales of the moving rod 3 facilitate reading the movement distance of the extending rod 4 and confirming whether the distance from the input shaft plane of the measured steering gear to the gear and rack meshing point meets the design requirements.

[0036] The connecting surface of the connecting block 2 and the moving rod 3 is provided with a square block with protrusions to ensure a stable connection between the connecting block 2 and the moving rod 3. When the connecting block 2 rotates, the moving rod 3 can rotate with the connecting block 2.

[0037] The connecting surface of the connecting rod 5 and the interface detection mechanism 6 is provided with a square block with protrusions to ensure a stable connection between the connecting rod 5 and the interface detection mechanism 6. When the connecting rod 5 rotates, the interface detection mechanism 6 can rotate with the connecting rod 5.

[0038] See Figure 7 In operation, this invention first selects a suitable interface shape shim 63 or a combination of interface shape shims 63 according to the input shaft interface 7, and assembles the interface detection mechanism 6. Next, the adjusting nut connecting mechanism 1 connects to the adjusting nut interface 8 of the steering gear pressure block position. The connecting block 2 can rotate on the adjusting nut connecting fixture 1 to adjust the relative angle of the moving rod 3 with respect to the plane of the steering gear pressure block, thereby matching the steering gear housing angle ϴ. Simultaneously, the moving rod 3 rotates with the connecting block 2. After the angle adjustment is completed and fixed, the extending rod 4 moves upward on the moving rod 3 to match the distance from the steering gear input shaft plane to the gear rack meshing point. After the height of the extending rod 4 is adjusted and fixed, the connecting rod 5 moves back and forth on the extending rod 4 to match the gear rack meshing center distance of the steering gear. This completes the adjustment of the phase angle detection fixture structure dimensions, achieving the adaptation of the fixture dimensions and steering gear parameters.

[0039] If the phase angle of the steering gear is accurate, the input shaft interface 7 of the steering gear passes through the interface detection mechanism 6. If the steering gear input shaft direction is incorrectly assembled or the input shaft interface size is incorrect, the input shaft interface 7 of the steering gear cannot interface with the detection mechanism 6, thus achieving the purpose of detection and error prevention.

[0040] This invention adjusts the angle, length, and detection hole size of the structure to adapt to the input shaft interface of different steering gear models, achieving phase angle detection and effectively reducing steering gear development resources and improving development efficiency. In the early stages of steering gear development, this invention can also control other key parameters such as housing angle and input shaft size.
