Description

Technical Field

[0001] This application relates to the field of tooling and fixture technology, specifically a tooling for machining steering knuckles on vehicle axles. Background Technology

[0002] With the rapid development of the automotive industry, higher demands are being placed on the machining accuracy and production efficiency of axle components such as steering knuckles. Traditional machining methods typically rely on tooling fixtures of a single size, which is inflexible and inefficient when dealing with steering knuckles of various models and sizes. Furthermore, due to the complex structure of steering knuckles, problems such as inaccurate positioning and unstable support are prone to occur during machining. Commonly used fixtures are often designed for specific dimensions, requiring the replacement of the entire fixture for steering knuckles of different sizes or shapes. This not only increases costs but also reduces production efficiency. During machining, the through holes in the steering knuckle are not perpendicular to each other, and even after the shaft end of the steering knuckle is fixed, the workpiece cannot be completely fixed. If the steering knuckle cannot be accurately positioned, it may lead to machining errors, affecting the final product quality. The lack of effective lateral support and guiding functions can easily cause workpiece vibration or displacement during machining, further affecting machining accuracy. Summary of the Invention

[0003] The technical problem to be solved by this application is to overcome the existing defects and provide a tooling for machining steering knuckles on vehicle axles, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a tooling for machining steering knuckles on vehicle axles, comprising a pad plate, a support guide plate vertically arranged on the upper surface of the pad plate, a bushing mounting hole for placing a fixed sleeve on the support guide plate, lateral strip holes for placing an auxiliary top bearing seat around the bushing mounting hole, a top bearing mounting hole between the lateral strip holes, a side positioning shaft being mounted on the top bearing mounting hole via a locking shaft, and a pressure seat being provided behind the support guide plate.

[0005] As a preferred technical solution of this utility model, the lateral strip hole is inclined, and the angle between it and the vertical direction is 30 degrees to 50 degrees.

[0006] As a preferred technical solution of this utility model, the auxiliary top shaft seat includes a guide shaft locking sleeve and a top shaft. The number of guide shaft locking sleeves is two. The two guide shaft locking sleeves are respectively arranged on the front and rear sides of the support guide plate and are sleeved and locked with the top shaft.

[0007] As a preferred technical solution of this utility model, the bushing mounting hole is a stepped hole, and a flange hole corresponding to the fixing sleeve is provided on the step.

[0008] As a preferred technical solution of this utility model, the number of fixing sleeves is three, and the inner diameters of the three fixing sleeves are different.

[0009] As a preferred technical solution of this utility model, the side positioning shaft includes a side positioning shaft and a positioning placement seat. The side positioning shaft is sleeved in the positioning shaft hole on the positioning placement seat, and the positioning placement seat is installed in the top seat mounting hole on the support guide plate.

[0010] Compared with the prior art, the lateral strip hole and top seat mounting hole in this application allow the auxiliary top shaft seat and side positioning shaft to be finely adjusted according to actual needs, further ensuring the accurate position of the workpiece during processing and reducing quality problems caused by inaccurate positioning. At the same time, this tooling can adapt to the processing needs of steering knuckles of various sizes without replacing the entire tooling or making complex adjustments, which greatly improves the versatility and flexibility of the equipment. By locking the top shaft with the guide shaft locking sleeve and applying appropriate pressure to the steering knuckle with the pressure seat, vibration and offset phenomena during processing are effectively reduced, and processing stability is improved.

[0016] 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 a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0017] Please see Figure 1-4This application provides a technical solution: a tooling for machining steering knuckles on a vehicle axle, including a pad plate 9, a support guide plate 1 vertically arranged on the upper surface of the pad plate 9, and a bushing mounting hole 6 for placing a fixing sleeve on the support guide plate 1.

[0018] The pad plate 9 provides a stable platform, which provides a fundamental guarantee for stability and accuracy during the machining process.

[0019] More specifically, it has strip-shaped holes around its perimeter, which facilitates connection to an external worktable. Because of the strip-shaped holes, its position can be finely adjusted to ensure machining accuracy.

[0020] The support guide plate 1 is the main vertical support component, which supports components such as the bushing mounting hole 6, and provides necessary lateral support and guidance for the steering knuckle parts, ensuring that the parts are positioned accurately during the machining process.

[0021] The bushing mounting hole 6 is located on the support guide plate 1 and is used to place the fixing sleeve. Select the appropriate fixing sleeve according to the specific specifications of the steering knuckle to be processed and accurately position it in the predetermined position.

[0022] The bushing mounting hole 6 is surrounded by lateral strip holes 3 for mounting auxiliary top shaft seats. A top seat mounting hole 10 is provided between the lateral strip holes 3. A side positioning shaft is mounted on the top seat mounting hole 10 by a locking shaft. A pressure seat 2 is also provided behind the support guide plate 1.

[0023] The lateral strip-shaped hole 3 is provided around the bushing mounting hole 6 for mounting the auxiliary top shaft seat. The strip-shaped hole in the lateral strip-shaped hole 3 allows the auxiliary top shaft seat to be finely adjusted to meet the machining requirements of steering knuckle parts of different sizes and types.

[0024] Specifically, the auxiliary top shaft seat includes a guide shaft locking sleeve 4 and a top shaft 5. There are two guide shaft locking sleeves 4, which are respectively arranged on the front and rear sides of the support guide plate 1 and are sleeved and locked with the top shaft 5.

[0025] Furthermore, the guide shaft locking sleeve 4 provides stable support and precise positioning, ensuring that the outer end of the top shaft 5 is fitted with a positioning device for locking the workpiece from the outside, maintaining stability and preventing displacement or loosening.

[0026] The top shaft 5, through its cooperation with the guide shaft locking sleeve 4, can be adjusted within the lateral slot 3 and ultimately locked in the desired position. During machining, the top shaft 5 applies necessary support force to the workpiece, ensuring the steering knuckle is accurately positioned during machining and does not shift due to external forces.

[0027] The top mounting hole 10 is used to install the side positioning shaft through the locking shaft, so that the side positioning shaft can be flexibly adjusted according to the actual processing needs, ensuring that the workpiece maintains accurate positioning during the processing.

[0028] Specifically, the side positioning shaft includes a side positioning shaft 7 and a positioning placement seat 8. The side positioning shaft 7 is sleeved in the positioning shaft hole on the positioning placement seat 8, and the positioning placement seat 8 is installed in the top seat mounting hole 10 on the support guide plate 1.

[0029] The lateral positioning shaft 7 is fitted into the positioning shaft hole on the positioning placement seat 8.

[0030] Specifically, the top mounting hole 10 is provided with at least three through holes, in which the positioning seat 8 can be freely installed according to the shape and size of the workpiece. At the same time, the positioning seat 8 is also provided with multiple lateral positioning shafts 7, which can be freely installed on the positioning seat 8 to achieve precise positioning of the workpiece, ensure the precise positioning of the machining steering knuckle during the machining process, and avoid quality problems caused by inaccurate positioning.

[0031] The pressure seat 2 is applied to workpieces with flat ends, which facilitates the application of stable pressure to the steering knuckle, ensuring its stability throughout the machining process. The pressure seat 2 prevents the workpiece from rotating during machining, which helps to improve machining accuracy and product quality.

[0032] Furthermore, the lateral strip hole 3 is inclined, and its angle with the vertical direction is 30 degrees to 50 degrees.

[0033] The lateral strip hole 3 is tilted so that the auxiliary top spindle can support the workpiece at a specific angle. Compared with simple support in the vertical direction, it can increase the support range, effectively reduce the vibration or movement of the workpiece, and adapt to various workpiece shapes, ensuring that each workpiece can be properly supported and fixed.

[0034] Furthermore, the bushing mounting hole 6 is a stepped hole, and a flange hole corresponding to the fixing sleeve is provided on the step.

[0035] The bushing mounting hole 6 is a stepped hole to enhance the installation stability and positioning accuracy of the fixing sleeve on the tooling.

[0036] The flange holes on the steps are typically used to increase connection strength or provide additional support. The flange holes allow the flange portion of the fixed sleeve to be accurately embedded in the bushing mounting hole 6, further enhancing the connection stability between the fixed sleeve and the bushing mounting hole 6, helping to improve the rigidity of the overall structure, and also ensuring the precise positioning of the steering knuckle during the machining process.

[0037] Furthermore, the number of fixing sleeves is three, and the inner diameters of the three fixing sleeves are not the same.

[0038] In use: Select a suitable fixing sleeve according to the specific specifications of the steering knuckle to be processed. Connect the pad plate 9 to the external worktable through the strip holes around its perimeter, and fine-tune its position to ensure processing accuracy. Carefully insert the selected fixing sleeve into the bushing mounting hole 6, ensuring that its flange part is accurately embedded in the flange hole of the stepped hole and fixed. This enhances the installation stability and positioning accuracy of the fixing sleeve on the tooling, and also improves the rigidity of the overall structure. Adjust the position of the auxiliary top shaft seat according to the specific shape and size of the steering knuckle to be processed, allowing the top shaft 5 to be adjusted, thereby providing optimal support force. Lock the top shaft 5 in the required position through the guide shaft locking sleeve 4, ensuring that the top shaft 5 is in contact with one plane of the workpiece and remains stable and does not shift during processing. Freely install the positioning placement seat 8 according to the shape and size of the workpiece. The positioning placement seat 8 also has multiple positions for installing the lateral positioning shaft 7, which can be flexibly adjusted as needed to ensure accurate positioning of the steering knuckle during processing.

[0039] When the workpiece has a flat structure on its shaft end, the pressure seat 2 applies appropriate pressure to the flat structure on the steering knuckle shaft end. This prevents the steering knuckle from rotating during machining, improving machining accuracy and product quality.

[0040] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
