Description

Technical Field

[0001] This application relates to the field of steering wheel testing technology, specifically a steering wheel testing fixture. Background Technology

[0002] In the field of automotive parts manufacturing and testing, the steering wheel, as a core component for driving operation, directly affects the driver's handling experience and driving safety. Therefore, accurate and comprehensive testing of the steering wheel is a crucial step in ensuring vehicle safety performance.

[0003] However, traditional steering wheel inspection processes have many shortcomings. On the one hand, traditional steering wheel inspection fixtures are often single-function, only capable of inspecting one or a few specific items of the steering wheel at a time. This means that after completing the inspection of one item, the operator needs to remove the steering wheel from the fixture and then reinstall it into another fixture or adjust the current fixture to accommodate the next inspection item. This is not only time-consuming and labor-intensive, but also reduces inspection efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a steering wheel inspection fixture, which has advantages such as easy clamping and easy inspection, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a steering wheel detection fixture, including a base plate, a main body fixedly connected to the upper surface of the base plate, the top of the front of the main body being a downwardly inclined surface, and auxiliary wings fixedly connected to the left and right sides of the main body, the top of the two auxiliary wings that are far apart from each other being both set as downwardly inclined surfaces.

[0006] The upper surface of the main body and the upper surfaces of the two ailerons are provided with a set of insertion holes, and the inner bottom wall of each insertion hole is provided with a connecting hole, and each connecting hole is provided with an internal thread.

[0007] Each of the aforementioned sockets is equipped with a detection post inside, and a threaded post is fixedly connected to the bottom end of each of the aforementioned detection posts;

[0008] Each of the ailerons has a slot on both the front and back sides, and each slot has a mounting hole on its inner wall. Each mounting hole is internally threaded.

[0009] Each of the insertion slots is provided with a clamping assembly inside, and each clamping assembly includes an insertion block. Each insertion block is slidably inserted into the insertion slot adjacent to it. Each insertion block has a clamping block slidably connected to its outer surface. Each clamping block has a fixed post threadedly connected to its top end. Each insertion block has a rotating post rotatably connected inside it. Each rotating post has a threaded end near the aileron.

[0010] By integrating the detection column and clamping assembly into one unit, the steering wheel can be comprehensively inspected for its hole positions, dimensions, and edge shapes without frequent disassembly during the inspection process. This design significantly improves inspection efficiency and reduces the additional time and costs associated with disassembling and reassembling the steering wheel. The rounded corner design and polishing of the detection column, along with the anti-slip features of the clamping assembly and the fastening function of the fixing column, together ensure the accuracy and stability of the inspection process, helping to reduce inspection errors and improve the reliability of the inspection results.

[0011] Furthermore, each of the threaded posts is threadedly connected to its adjacent connecting hole.

[0012] The above scheme and settings make it easy for users to disassemble and replace the detection column.

[0013] Furthermore, the top of each detection column is rounded.

[0014] The above scheme and settings facilitate the insertion of the detection column into the hole of the external steering wheel.

[0015] Furthermore, the outer surface of each of the detection columns is polished.

[0016] The above scheme and settings can reduce the surface friction coefficient of the detection column, thereby improving insertion smoothness.

[0017] Furthermore, the upper surface of each of the inserts is provided with an anti-slip feature.

[0018] The above scheme and settings can improve the friction coefficient when the fixed post and the insert block are in contact, thereby improving the fixing stability.

[0019] Furthermore, the threaded end of each of the rotating columns is threadedly connected to its adjacent mounting hole.

[0020] The above scheme and settings facilitate the connection between the clamping assembly and the aileron.

[0021] Furthermore, a first handle is fixedly connected to the top of each of the fixed posts.

[0022] The above solution, with the first handle, makes it easy for users to rotate the fixed column.

[0023] Furthermore, a second handle is fixedly connected to the end of each of the rotating columns away from the aileron.

[0024] The above solution, with the addition of a second handle, makes it easier for users to rotate the rotating column.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0026] This steering wheel inspection fixture integrates the inspection column and clamping assembly into one unit, eliminating the need for frequent disassembly of the steering wheel during inspection. It enables comprehensive inspection of the steering wheel's hole positions, dimensions, and edge shapes. This design significantly improves inspection efficiency and reduces the additional time and costs associated with disassembling and reassembling the steering wheel. The rounded corner design and polishing of the inspection column, along with the anti-slip features of the clamping assembly and the secure fastening function of the fixing column, collectively ensure the accuracy and stability of the inspection process, helping to reduce inspection errors and improve the reliability of the inspection results.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figure 1 , Figure 2 and Figure 3A steering wheel detection fixture in this embodiment includes a base plate 1. A main body 2 is fixedly connected to the upper surface of the base plate 1. The top front of the main body 2 is a downward-sloping surface. Auxiliary wings 3 are fixedly connected to both sides of the main body 2. The top of the two auxiliary wings 3 that are far apart from each other are both set as downward-sloping surfaces. Through the above settings, the purpose of fitting with the steering wheel can be achieved. A set of insertion holes 4 are opened on the upper surface of the main body 2 and the upper surface of the two auxiliary wings 3. A connecting hole 5 is opened on the inner bottom wall of each insertion hole 4. Each connecting hole 5 is internally threaded.

[0036] Please see Figure 1 , Figure 2 and Figure 5 Each of the aforementioned insertion holes 4 is equipped with a detection post 6 inside, and a threaded post 7 is fixedly connected to the bottom end of each detection post 6. The detection post 6 enables the detection of the position and size of the hole in the steering wheel. Each threaded post 7 is threadedly connected to its adjacent connection hole 5. This configuration facilitates the user's disassembly and replacement of the detection post 6. The top end of each detection post 6 is rounded, which facilitates the insertion of the detection post 6 into the hole of the external steering wheel. The outer surface of each detection post 6 is polished, which reduces the surface friction coefficient of the detection post 6 and improves the smoothness of insertion.

[0037] Please see Figure 1 , Figure 2 and Figure 3 Each aileron 3 has a slot 8 on both its front and back sides. Each slot 8 has an inner wall with a mounting hole 9, and each mounting hole 9 has an internal thread. Each slot 8 has a clamping assembly 10 inside, and each clamping assembly 10 includes a plug 1001. Each plug 1001 is slidably plugged into its adjacent slot 8. Each plug 1001 has a clamping block 1002 slidably connected to its outer surface. Each clamping block 1002 has a fixed post 1003 threadedly connected to its top. The sliding connection between the clamping block 1002 and the plug 1001 limits the movement of the steering wheel edge. Rotating the fixed post 1003 to make it tightly contact the plug 1001 achieves the purpose of fixing the clamping block 1002. Each plug 1001 has a rotating post 1004 rotatably connected inside, and each rotating post 1004 has a threaded end near the aileron 3.

[0038] Please see Figure 1 , Figure 2 and Figure 4Each of the insert blocks 1001 has an anti-slip surface. This design increases the coefficient of friction when the fixing post 1003 contacts the insert block 1001, thereby improving the fixing stability. The threaded end of each rotating post 1004 is threaded to the mounting hole 9 adjacent to it. This design facilitates the connection between the clamping assembly 10 and the aileron 3. Each fixing post 1003 has a first handle 11 fixedly connected to its top. The first handle 11 facilitates the user's rotation of the fixing post 1003. Each rotating post 1004 has a second handle 12 fixedly connected to its end away from the aileron 3. The second handle 12 facilitates the user's rotation of the rotating post 1004.

[0039] This embodiment of a steering wheel inspection fixture integrates the inspection post 6 and the clamping assembly 10 into one unit. It eliminates the need for frequent disassembly of the steering wheel during the inspection process, enabling comprehensive inspection of the steering wheel hole positions, dimensions, and edge shapes. This design significantly improves inspection efficiency and reduces the additional time and costs incurred due to disassembly and reassembly of the steering wheel. The rounded corner design and polishing of the inspection post 6, along with the anti-slip features of the clamping assembly 10 and the fastening function of the fixing post 1003, jointly ensure the accuracy and stability of the inspection process, helping to reduce inspection errors and improve the reliability of the inspection results.

[0040] It should be noted that when operating the steering wheel testing fixture of this embodiment, the operator should ensure that the steering wheel is correctly placed in the fixture to avoid forcibly installing it and causing damage to the fixture or the steering wheel. At the same time, when rotating the fixing column 1003 and the rotating column 1004, moderate force should be applied to avoid excessive tightening that could damage the threads or loosen the clamping assembly 10.

[0041] The working principle of the above embodiment is as follows: First, the operator places the steering wheel between the main body 2 and the auxiliary wing 3 of the fixture. Utilizing the beveled design at the top of the main body 2 and the auxiliary wing 3, the steering wheel naturally fits into the fixture. During placement, the holes on the steering wheel can engage with the detection post 6. If the steering wheel cannot be installed, it indicates a defect in the hole machining. The rounded corner design and polishing of the detection post 6 allow it to be easily inserted into the holes of the steering wheel, reducing frictional resistance and improving insertion smoothness, thus enabling the inspection of the holes. The sliding connection design between the holding block 1002 and the insert block 1001 allows the holding block 1002 to slide on the surface of the insert block 1001, so that one side of the holding block 1002 contacts the outer edge of the steering wheel. Then, by rotating the fixing post 1003, it is brought into close contact with the insert block 1001, thereby fixing the holding block 1002. The anti-slip design of the clamping assembly 10 and the fastening function of the fixing post 1003 together ensure the stability and reliability of the clamping process, achieving the purpose of firmly clamping the steering wheel and facilitating subsequent inspection items of the steering wheel.
