Description

Technical Field

[0001] The present application relates to the field of detection fixtures, and in particular to a yoke rapid detection fixture. Background Art

[0002] The yoke is a key component in automotive steering systems, primarily used for securing connections and adjusting steering. The center shaft is connected to the steering gear via the yoke. The yoke is equipped with a spline slot for connection to the steering gear. A keyhole is located on one side of the spline slot, and the spline is secured with bolts. As the automotive industry continues to increase its requirements for component dimensions, clearances, and installation compatibility, ensuring the high precision of these components has become a crucial step in the manufacturing process.

[0003] Among existing methods for inspecting yokes, common approaches include spot checks using coordinate measuring machines (CMMs) and random inspections during the assembly process. CMMs can provide highly accurate measurements, but in practice, they suffer from high equipment costs, complex operation, and lengthy inspection times. While random inspections during the assembly process can provide a certain degree of control over product quality, their low coverage makes it impossible to guarantee that every product meets quality standards, potentially leading to substandard products entering the market. Furthermore, both methods require significant human and material resources, increasing operating costs for businesses.

[0004] Therefore, an efficient, simple and economical detection tool is urgently needed to solve this problem. Utility Model Content

[0005] In order to facilitate the detection of the relative position accuracy of the spline groove and the lock hole on the yoke, improve efficiency and reduce costs, the present application provides a yoke quick inspection fixture.

[0006] The yoke quick inspection tool provided in this application adopts the following technical solutions:

[0007] A yoke quick inspection tool, comprising a spline plug gauge and a detection pin; the spline plug gauge is used to be plugged into and matched with the spline groove of the yoke, and the detection pin is used to be plugged into and matched with the locking hole of the yoke;

[0008] The spline plug gauge is provided with a detection groove, which is configured as a stepped groove and includes a first groove and a second groove, wherein the first groove is deeper than the second groove;

[0009] The first groove is used to cooperate with the detection pin, and the step surface between the first groove and the second groove is used to abut against the detection pin.

[0010] By adopting the above technical solution, when performing inspection work, the spline plug gauge is inserted into the spline groove of the yoke, so that the first groove is aligned with the locking hole, and then the inspection pin is inserted into the locking hole and the inspection pin is located in the first groove. Then, the spline plug gauge is pulled to check whether the step surface can abut against the inspection pin. If so, it meets the requirements; if not, it does not meet the requirements. Therefore, the yoke quick inspection fixture can effectively reduce the difficulty of inspection, improve inspection efficiency, and help reduce production costs. In addition, the height of the step can be adjusted to achieve adjustment of the inspection accuracy.

[0011] Preferably, the step surface is configured as an inclined surface.

[0012] By adopting the above technical solution, the end face of the step surface is abutted against the detection pin, and the edge of the step surface is prevented from abutting against the detection pin, thereby reducing the probability of the yoke quick detection fixture being damaged due to collision.

[0013] Preferably, the detection pin comprises a plurality of segments with gradually increasing diameters.

[0014] By adopting the above technical solution, multiple segments are gradually inserted into the locking hole, which helps to reduce the difficulty of aligning the detection pin with the locking hole and facilitates operation.

[0015] Preferably, the spline plug gauge includes a handle portion and a spline portion, and the spline portion is rotatably connected to the handle portion.

[0016] By adopting the above technical solution, the staff can rotate the spline part so that the spline part accurately matches the spline groove, thereby improving the convenience of operation.

[0017] Preferably, a locking sleeve is sleeved on the handle portion, the locking sleeve and the handle portion are slidably arranged, and a key groove cooperating with the spline portion is formed on the inner wall of the locking sleeve.

[0018] By adopting the above technical solution, the locking sleeve can keep the spline portion and the handle portion relatively fixed, so as to facilitate the detection operation.

[0019] Preferably, an abutment platform is further provided on the inner wall of the locking sleeve, and the abutment platform is used to abut against the end face of the spline portion.

[0020] By adopting the above technical solution, the abutment platform can limit the relative position of the locking sleeve and the spline portion, so that the locking sleeve only cooperates with the end of the spline portion, ensuring that the spline portion has sufficient working length.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The yoke quick inspection fixture uses a spline gauge and an inspection pin to effectively detect the relative position accuracy of the spline groove and lock hole on the yoke, improving inspection efficiency and reducing inspection time and labor costs.

[0023] 2. The detection groove is designed as a stepped groove. The step surface between the first groove and the second groove can precisely abut the detection pin, ensuring detection accuracy and avoiding missed detection and false detection.

[0024] 3. The step surface is set as an inclined surface, which reduces the probability of wear when the detection pin contacts the step surface and improves the durability and reliability of the inspection tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following is combined with Figure 1-2 This application is described in further detail.

[0029] Example 1

[0030] The embodiment of the present application provides a yoke quick detection tool, referring to Figure 1 The spline plug gauge 1 includes a spline plug gauge 1 and a detection pin 2. The spline plug gauge 1 is used to plug and mate with the spline groove 31 of the yoke 3, and the detection pin 2 is used to plug and mate with the locking hole 32 of the yoke 3. The spline plug gauge 1 is provided with a detection groove 13. The detection groove 13 is configured as a stepped groove and includes a first groove 131 and a second groove 132. The first groove 131 is deeper than the second groove 132. The first groove 131 is used to mate with the detection pin 2, and the step surface 133 between the first groove 131 and the second groove 132 is used to abut against the detection pin 2, thereby improving detection efficiency and accuracy and reducing detection costs.

[0031] The detection pin 2 can be composed of multiple segments, each with a gradually increasing diameter. This design helps to reduce the difficulty of aligning the detection pin 2 with the locking hole 32, making operation more convenient. The material of the detection pin 2 can be selected from high-strength steel or carbon fiber to ensure its durability after repeated use. The transition portion between each segment can be designed to be circular arc-shaped to reduce wear on the locking hole 32.

[0032] During use, the operator first inserts the spline feeler gauge 1 into the spline groove 31 of the yoke 3, aligning the first groove 131 with the locking hole 32. The operator then inserts the test pin 2 into the locking hole 32, positioning the test pin 2 within the first groove 131. The operator then pulls the spline feeler gauge 1 to check whether the stepped surface 133 abuts the test pin 2. If so, the relative positional accuracy of the spline groove 31 and the locking hole of the yoke 3 meets the requirements; otherwise, further adjustment or repair is required.

[0033] By designing a spline plug gauge 1 with a stepped groove and a multi-segmented inspection pin 2, this embodiment provides an efficient, simple, and economical tool for inspecting yokes 3. Compared to traditional coordinate measuring machines and random inspections during assembly, this embodiment significantly reduces inspection difficulty and cost, improves inspection efficiency and accuracy, and helps companies reduce operating costs while ensuring product quality.

[0034] Example 2

[0035] The embodiment of the present application provides a yoke quick detection tool, which is different from the embodiment 1 in that, referring to Figure 2 The spline plug gauge 1 in the embodiment of the present application includes a handle portion 11 and a spline portion 12. The handle portion 11 and the spline portion 12 are rotatably connected. The spline portion 12 can rotate freely on the handle portion 11. In this way, during use, the operator can adjust the angle of the spline portion 12 by rotating the handle portion 11, making it easier to align it with the spline groove 31.

[0036] Furthermore, a locking sleeve 14 is sleeved on the handle 11 of the spline plug gauge 1. The locking sleeve 14 slides with the handle 11, and a keyway is formed on the inner wall of the locking sleeve 14 to cooperate with the spline portion 12. This design ensures that the spline portion 12 and the handle 11 remain relatively fixed during the inspection process, thereby improving the stability of the inspection.

[0037] An abutment platform 141 is further provided on the inner wall of the locking sleeve 14, and the abutment platform 141 is used to abut against the end face of the spline portion 12. This design can limit the relative position of the locking sleeve 14 and the spline portion 12, ensuring that the spline portion 12 has sufficient working length.

[0038] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
