Abstract
Description
Technical Field
[0001] This utility model belongs to the field of auto parts and relates to a fixture, and particularly to an automotive steering knuckle fixture. Background Technology
[0002] Traditional steering knuckle fixtures typically employ a single-station design, clamping only one workpiece at a time for processing. This results in low production efficiency, making it difficult to meet the high cycle time and capacity requirements of modern production lines. Furthermore, due to the diverse range of car models, steering knuckle dimensions and angles vary, while traditional fixtures often use fixed positioning elements lacking effective adjustment mechanisms. When switching between different steering knuckle models, the entire fixture often needs to be replaced or extensive, tedious manual adjustments required. This not only extends production line downtime and reduces equipment utilization but also significantly impacts production flexibility and automation.
[0003] Meanwhile, during the clamping process, whether the workpiece is installed in place usually depends on the operator's visual observation and experience judgment, which carries the risk of misjudgment. This may cause the workpiece to shift or vibrate during processing, leading to out-of-tolerance machining accuracy or even scrapping, thus affecting the stability and consistency of machining quality. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an automotive steering knuckle fixture to solve these issues.
[0005] The purpose of this utility model can be achieved through the following technical solution: an automotive steering knuckle fixture, comprising a rocker arm mechanism and a fixed plate disposed on the rocker arm mechanism, characterized in that the fixed plate is provided with two fixture plates in a relatively opposite structure to form a dual-station machining; Each of the tooling plates is provided with a mandrel at its center for quick positioning and support of the steering knuckle center. Each of the tooling plates is provided with multiple clamping devices for clamping and fixing the steering knuckle, and multiple positioning devices for auxiliary positioning of the steering knuckle horn position. The tooling plate is also equipped with a positioning sensor for detecting whether the steering knuckle is installed in the correct position; The positioning device includes a first positioning shaft and a second positioning shaft, which are used to position the steering knuckle of the vehicle. The first positioning shaft and the second positioning shaft are mounted on the fixed plate through a quick-change plate to adapt to the positioning of steering knuckle angles of different sizes and specifications. The clamping device includes a clamping block and a clamping cylinder, wherein the clamping cylinder is used to drive the clamping block to perform clamping or releasing actions on the steering knuckle.
[0006] In the aforementioned automotive steering knuckle fixture, the quick-change plate is connected to the fixed plate via adjustable bolts, making the mounting positions of the first positioning shaft and the second positioning shaft adjustable on the fixed plate.
[0007] In the aforementioned automotive steering knuckle fixture, the positioning sensor is a magnetic induction proximity sensor.
[0008] In the aforementioned automotive steering knuckle fixture, the mandrel is configured in a frustum shape to facilitate radial positioning after clamping and fixing.

Detailed Implementation
[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2As shown, this automotive steering knuckle fixture includes a rocker arm mechanism 1 and a fixed plate 2 mounted on the rocker arm mechanism 1. The fixed plate 2 has two opposing fixture plates 3, forming a dual-station machining process. Each fixture plate 3 has a mandrel 4 at its center for quick positioning and support of the steering knuckle center. Each fixture plate 3 has multiple clamping devices for clamping and fixing the steering knuckle, and multiple positioning devices for auxiliary positioning of the steering knuckle's knuckle corner position. The fixture plate 3 also has a positioning sensor 5 for detecting whether the steering knuckle installation position is in place. The positioning device includes a first positioning shaft 6 and a second positioning shaft 7, which are used to position the steering knuckle corner of the automotive steering knuckle, respectively. The first positioning shaft 6 and the second positioning shaft 7 are mounted on the fixed plate 2 via a quick-change plate 8 to accommodate steering knuckle corner angle positioning of different sizes and specifications. The clamping device includes a clamping block 9 and a clamping cylinder 10. The clamping cylinder 10 is used to drive the clamping block 9 to perform clamping or releasing actions on the steering knuckle.
[0015] The quick-change plate 8 is connected to the fixed plate 2 via adjustable bolts, allowing the mounting positions of the first positioning shaft 6 and the second positioning shaft 7 on the fixed plate 2 to be adjusted. The positioning sensor 5 is a magnetic induction proximity sensor. The spindle 4 has a frustum-shaped structure, facilitating radial limiting after clamping and fixing.
[0016] Two opposing tooling plates 3 mounted on the fixed plate 2 allow for the simultaneous clamping of two steering knuckles, thereby improving processing efficiency. The mandrel 4 at the center of each tooling plate 3 has a frustum-shaped structure, enabling rapid centering and support of the steering knuckle, ensuring its stability during processing. The clamping device, driven by the clamping cylinder 10, performs clamping or releasing actions on the pressure block 9, achieving reliable fixation of the steering knuckle. The positioning device includes a first positioning shaft 6 and a second positioning shaft 7, mounted on the fixed plate 2 via a quick-change plate 8. Its position can be adjusted to accommodate steering knuckle angle positioning of different sizes and specifications, ensuring processing accuracy. Furthermore, the positioning sensor 5 detects whether the steering knuckle is properly positioned, providing real-time feedback to prevent misoperation.
[0017] The dual-station structure significantly improves production efficiency, allowing simultaneous processing of two steering knuckles and reducing clamping and material changeover time. The frustum-shaped design of its mandrel 4 not only facilitates rapid positioning but also provides effective radial limiting, enhancing the stability of the steering knuckle during processing. The accompanying clamping device is cylinder-driven, achieving automated clamping with simple operation and rapid response. The positioning device is flexibly adjustable via quick-change plate 8 and adjustable bolts, enabling the tooling to adapt to various steering knuckle specifications and improving the fixture's versatility and adaptability.
