Description

Technical Field

[0001] The invention belongs to the technical field of automotive parts testing, and particularly relates to a height valve angle testing tooling. Background Art

[0002] The height valve is used in a vehicle suspension system with an air spring (airbag). By dynamically sensing the change in vehicle height, it can timely complete the actions of intake or exhaust to adjust the height of the air spring (airbag), improve the comfort of passengers, and prevent the road surface from being damaged by the impact of the wheels. When the height valve is working, the handle swings reciprocally by a certain angle to drive the valve core to control the intake and exhaust of the valve body. Among them, the left and right yaw angles of the height valve are an important detection index before leaving the factory. At present, there is no fast and simple testing tooling on the market to complete the above detection. Summary of the Invention

[0003] The purpose of the invention is to provide a height valve angle testing tooling to solve the above problems.

[0004] To achieve the above purpose, the invention discloses a height valve angle testing tooling, which includes a bottom plate and a longitudinal sliding assembly, a transverse sliding assembly, a transverse displacement reader and a valve body mounting bottom plate for mounting the height valve, which are installed on the bottom plate. The longitudinal sliding assembly includes a longitudinal slide rail and a longitudinal slider that vertically slides on the longitudinal slide rail relative to the height valve. A rotating shaft that can pivotally connect to the handle hole of the height valve is arranged on the longitudinal slider. The transverse sliding assembly includes a transverse slide rail and a transverse slider that horizontally slides on the transverse slide rail relative to the height valve. The longitudinal slide rail is installed on the transverse slider, and the transverse slider is connected to the transverse displacement reader.

[0005] Further, it further includes a vertical sliding assembly. The vertical sliding assembly includes a vertical screw rod, a vertical adjusting handwheel, a vertical slide rail and a vertical slider that slide relative to each other.

[0022] The embodiments of the present invention are described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered by the claims.

[0023] like Figures 1-3 As shown, the present invention discloses a height valve angle test fixture, including a base plate 1 and a longitudinal sliding assembly mounted on the base plate 1, a transverse sliding assembly, a transverse displacement reader and a valve body mounting base plate 3 for mounting a height valve 2, the longitudinal sliding assembly including a longitudinal slide rail 4 and a longitudinal slider 5 vertically slidably connected to the longitudinal slide rail 4 relative to the height valve 2, the longitudinal slider 5 is provided with a rotating shaft 7 that can be pivotally connected to a handle hole 6 of the height valve 2, the transverse sliding assembly including a transverse slide rail 8 and a transverse slider 9 transversely slidably connected to the transverse slide rail 8 relative to the height valve 2, the transverse sliding assembly including a connected transverse screw 21 and a transverse adjustment hand wheel 22, the two ends of the transverse screw 21 are pivotally connected to the transverse slide rail 8, the transverse screw 21 is transmission-connected to the transverse slider 9, so that the transverse displacement of the transverse slider 9 can be accurately adjusted. The transverse slide rail 8 and the longitudinal slide rail 4 are vertically arranged, the longitudinal slide rail 4 is mounted on the transverse slider 9, and the transverse slider 9 is connected to the transverse displacement reader. Thus, when the handle 17 of the height valve 2 connected to the air source moves to one side from the center position following the transverse slider 9, it will also slide on the longitudinal slide rail 4 following the longitudinal slider 5. When the height valve 2 starts to take in or exhaust air, since the transverse displacement reader is connected to the transverse slider 9, the transverse displacement amount will be displayed synchronously. Since the distance from the rotation center of the height valve 2 to the transverse displacement reader is fixed, the intake and exhaust angles of the height valve 2 can be obtained by using the inverse tangent function relationship.

[0024] In this embodiment, in order to make the handle 17 perpendicular to the sliding direction of the horizontal slider 9 when at the central position, a vertical sliding component is further included. The vertical sliding component includes a vertical screw rod 25, a vertical adjusting handwheel 10, a vertical sliding rail 11 and a vertical slider 12 that are slidably connected to each other. The valve body mounting base plate 3 is mounted on the vertical slider 12. The rotating shaft 7 is of a tapered shaft structure. The vertical screw rod 25 is pivotally connected to the vertical sliding rail 11 and is in threaded transmission connection with the vertical slider 12. The vertical adjusting handwheel 10 is connected to the vertical screw rod 25. Thus, after the height valve 2 is installed on the valve body mounting base plate 3, the vertical adjusting handwheel 10 is adjusted to drive the vertical slider 12 to move downward. Due to the self-centering effect of the tapered shaft, the handle hole 6 can be completely engaged, so as to ensure that the connection line between the handle hole 6 and the rotation axis center of the handle 17 is perpendicular to the horizontal sliding rail 8.

[0025] In this embodiment, a valve body positioning support plate 13 is mounted on the valve body mounting base plate 3. A clamping groove 14 matching the shape of the height valve 2 is provided on the valve body positioning support plate 13. An arc structure matching the rounded corners of the height valve 2 is provided at the edge of the clamping groove 14. Compared with screw fixation, the clamping groove 14 can be quickly assembled and disassembled.

[0026] In this embodiment, meanwhile, in order to prevent the height valve 2 from loosening up and down, a pressing mechanism for pressing the height valve 2 into the clamping groove 14 is mounted on the base plate 1. The pressing mechanism is a quick clamp 15, and a pressing head 16 for pressing the height valve 2 is mounted on the quick clamp 15. When specifically arranged, the pressing head 16 is of a C-shaped structure, and an avoidance groove 18 for avoiding the connection part between the handle 17 on the height valve 2 and the height valve 2 is provided on the pressing head 16, so that the pressing head 16 will not interfere with the height valve 2 or the tooling when being pressed in or opened.

[0027] In this embodiment, the lateral displacement reader includes a main scale 19 and a vernier 20. The main scale 19 is supported and installed by the straight ruler support frames 23 at both ends. Displacement scale lines are provided on the main scale 19. The vernier 20 can be aligned with the displacement scale lines for convenient reading. It is installed parallel to the horizontal sliding rail 8. The vernier 20 is slidably connected to the main scale 19 and is fixedly connected to the longitudinal slider 5, so that the displacement amount of the handle 17 can be observed in real time.

[0028] In this embodiment, the vernier 20 is a digital display vernier with a zero-clearing function. The main body structure of the lateral displacement reader is improved from a digital display vernier caliper. The main scale 19 is supported by an equal-height sleeve 24 and fixed by screws.

[0029] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
