Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy automotive parts technology, and in particular to a quick-access inspection tool for steering knuckles. Background Technology

[0002] As a core component of the vehicle steering system, the quality of the steering knuckle directly impacts driving safety. Steering knuckles have a complex structure, typically featuring a slender upper control arm. The manufacturing process is cumbersome, with numerous quality control items. Furthermore, the slender upper control arm is prone to deformation during casting, machining, and heat treatment due to its own weight, mechanical stress, or temperature changes, leading to decreased product precision, assembly difficulties, and safety hazards. Currently, detecting and identifying deformation in the upper control arm of the steering knuckle often requires coordinate measuring machines (CMMs), which are inefficient and labor-intensive. Moreover, CMMs are expensive, frequently used, and have limited product coverage, making batch testing of steering knuckles impossible; only random sampling is possible, increasing the risk of missed detections and misjudgments, resulting in high quality risks.

[0003] Therefore, developing a quick-access steering knuckle inspection tool for practical steering knuckle inspection is an urgent problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide a quick inspection tool for steering knuckles to address the above-mentioned problems, thereby solving the issues of low work efficiency, easy omissions and misjudgments, and high quality risks in the existing steering knuckle deformation inspection process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A steering knuckle quick-access inspection tool includes a base plate with a positioning assembly. The positioning assembly includes a first support pillar corresponding to the lower control arm portion of the steering knuckle, and a second and third support pillars corresponding to the riser portion of the steering knuckle. Positioning holes are respectively formed on the steering knuckle corresponding to the first, second, and third support pillars, and the first, second, and third support pillars are inserted into the positioning holes. The tool also includes a detection assembly with a detection post corresponding to the upper control arm portion of the steering knuckle. The upper end face of the detection post is spaced apart from the upper control arm to form a detection slot for detecting deformation of the upper control arm portion. The deformation of the upper control arm portion of the steering knuckle is measured by measuring the width of the detection slot.

[0007] Preferably, the detection assembly further includes a measuring pin for measuring the width of the detection slot, wherein the measuring pin is provided with a go gauge that can pass smoothly through the detection slot and a stop gauge that cannot pass through the detection slot, corresponding to the width tolerance of the detection slot.

[0008] Preferably, multiple sets of measuring pins are configured, and each set of measuring pins is equipped with go gauges and no-go gauges with different tolerance sizes, so as to obtain specific data on the deformation of the control arm on the steering knuckle.

[0009] Preferably, the positioning assembly further includes a clamping structure for clamping the steering knuckle. The clamping structure includes a column fixedly connected to the base plate, a cantilever for clamping the steering knuckle is provided on the column, and a flexible pressure head is provided at the front end of the cantilever corresponding to the upper surface of the steering knuckle.

[0010] Preferably, the detection component further includes abutment posts for detecting the parting line height of the steering knuckle. The abutment posts are fixedly connected to the base plate, and three abutment posts are provided corresponding to the parting line of the outer edge of the steering knuckle riser. The three abutment posts together form an abutment space at the outer edge of the steering knuckle riser.

[0011] Preferably, two sets of the positioning component and the detection component are provided, corresponding to the left and right steering knuckles respectively, so that a pair of steering knuckles can be quickly detected at the same time.

[0012] The beneficial effects of this utility model are as follows: This utility model improves upon the traditional testing method where steering knuckle deformation detection relies entirely on coordinate measuring machines, thus increasing testing efficiency. It enables 100% inspection of steering knuckle products, avoiding missed inspections and misjudgments, and ensuring quality and safety. The control arm setting on the inspection column spacing avoids the problem of steering knuckle deformation interfering with the installation of the inspection fixture, improving the applicability of the fixture. This utility model can measure the specific value of steering knuckle deformation, providing data support for subsequent production process adjustments. The abutment column setting can serve as a height detection structure for the steering knuckle parting line, enriching the inspection function of the fixture, and also plays an auxiliary positioning role, ensuring the horizontal positioning angle of the steering knuckle and improving the positioning accuracy of the steering knuckle.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-3 As shown, a quick-access steering knuckle inspection tool includes a base plate 10. A positioning assembly is mounted on the base plate 10 for supporting and positioning the steering knuckle to be inspected. The positioning assembly includes a first support column 21 corresponding to the lower control arm 11 of the steering knuckle, and a second support column 22 and a third support column 23 corresponding to the riser portion 12 of the steering knuckle. Positioning holes are respectively formed on the steering knuckle corresponding to the first support column 21, the second support column 22, and the third support column 23. The first support column 21, the second support column 22, and the third support column 23 are inserted into the positioning holes, providing three-point support to stably support the steering knuckle on the positioning assembly. The quick-access inspection tool also includes a detection assembly for detecting deformation of the upper control arm 11. The detection assembly includes a detection post 31 corresponding to the upper control arm 13 of the steering knuckle. The upper end face of the detection post 31 is spaced apart from the upper control arm 13 to form a detection slot 34 for detecting deformation of the upper control arm 13. The deformation of the upper control arm 13 of the steering knuckle can be measured by measuring the width of the detection slot 34, thus completing the steering knuckle deformation detection.

[0020] This implementation method improves upon the current situation where steering knuckle deformation detection relies entirely on coordinate measuring machines, increasing detection efficiency and enabling 100% inspection of steering knuckle products. This avoids missed detections and misjudgments, ensuring quality and safety. The control arm 13, installed at intervals on the detection column 31, prevents interference from steering knuckle deformation from hindering the installation of the inspection fixture, thus improving the fixture's applicability.

[0021] As a preferred embodiment, the detection component further includes a measuring pin 32 for measuring the width of the detection slot 34. On the measuring pin 32, a go - gauge 321 that can smoothly pass through the detection slot 34 and a no - go - gauge 322 that cannot pass through the detection slot 34 are provided corresponding to the width dimensional tolerance of the detection slot 34. During detection, first, the steering knuckle to be detected is supported and positioned on the positioning component. The tester holds the measuring pin 32 and tries to pass the go - gauge 321 and the no - go - gauge 322 through the detection slot 34 between the upper control arm 13 and the detection column 31 on the steering knuckle respectively. If the go - gauge 321 smoothly passes through the detection slot 34 and at the same time the no - go - gauge 322 cannot pass through, it can be determined that the deformation detection of the upper control arm 13 of the steering knuckle is qualified; if the go - gauge 321 cannot smoothly pass through or the no - go - gauge 322 smoothly passes through, it can be determined that the deformation detection of the upper control arm 13 of the steering knuckle is unqualified.

[0022] Preferably, multiple sets of the measuring pins 32 are configured. For each set of measuring pins 32, the go - gauge 321 and the no - go - gauge 322 with different tolerance dimensions are provided. During detection, by using different measuring pins 32 to measure the detection slot 34, the specific data of the deformation amount of the upper control arm 13 of the steering knuckle can be measured, which is convenient for guiding subsequent process adjustment.

[0023] Preferably, the positioning component further includes a pressing structure for pressing the steering knuckle. The pressing structure includes a column 24 fixedly connected to the bottom plate 10. On the column 24, a cantilever 25 for pressing the steering knuckle is provided. At the front end of the cantilever 25, a flexible pressing head 26 is provided corresponding to the upper surface of the steering knuckle. After the steering knuckle to be detected is supported and positioned by the first column 24, the second pillar 22 and the third pillar 23, the flexible pressing head 26 of the pressing structure is pressed on the steering knuckle, firmly fixing the steering knuckle on the positioning component, ensuring the positioning accuracy of the steering knuckle. The flexible pressing head 26 can effectively avoid scratching the steering knuckle product.

[0024] Preferably, the detection component further includes a abutting column 33 for detecting the height of the parting line 14 of the steering knuckle. The abutting column 33 is fixedly connected to the bottom plate 10, and three abutting columns 33 are provided corresponding to the parting line 14 on the outer edge of the riser part 12 of the steering knuckle. The three abutting columns 33 enclose an abutting space for the outer edge of the steering knuckle riser. During detection, if the height of the parting line 14 meets the requirements, the steering knuckle is not interfered by the three abutting columns 33 and can smoothly fall into the abutting space; if the parting line 14 on the outer edge of the riser part 12 of the detailed installation exceeds the standard requirements, the parting line 14 will interfere with the abutting column 33, resulting in the steering knuckle not being able to smoothly fall into the abutting space, that is, it is determined that the height of the parting line 14 of the steering knuckle exceeds the standard. As a detection structure for the height of the parting line 14 of the steering knuckle, the abutting column 33 enriches the detection function of the inspection tool. At the same time, the setting of the detection column 31 can also play an auxiliary positioning role, ensuring the positioning angle of the steering knuckle in the horizontal direction and further improving the positioning accuracy of the steering knuckle.

[0025] Preferably, two sets of the positioning component and two sets of the detection component are provided, corresponding to the left and right steering knuckles respectively, so that the present invention can complete the quick detection of a pair of steering knuckles at the same time, thereby improving the detection efficiency.

[0026] The above-disclosed embodiments are merely specific examples of this utility model, but this utility model is not limited thereto. For those skilled in the art, any modifications made without departing from the principle of this utility model should be considered as protected by this utility model.
