Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling and fixture for welding steering knuckles. Background Technology

[0002] The steering knuckle is a crucial component of the steering axle, connecting the wheels to the suspension system to ensure smooth and responsive steering when the driver operates the steering wheel. The steering knuckle also bears the force transmission between the wheels and the vehicle body, and under driving conditions, it withstands varying impact loads, requiring high strength.

[0003] The steering knuckle has an irregular shape and is divided into left and right steering knuckles according to its assembly position. Existing technical solutions have the following shortcomings:

[0004] 1. After the existing fixture is clamped, vibration is likely to occur during the welding process, which can easily cause uneven welds on some steering knuckles and fail to meet the welding process requirements.

[0005] Second, the existing fixtures can only guarantee welding of the same workpiece in one direction at a time, resulting in fewer weld seams that can be reached and low work efficiency.

[0006] Third, the existing clamps are only suitable for clamping steering knuckles of the same model and specifications, and their applicability is not strong. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a tooling fixture for welding steering knuckles that has a simple structure, does not obstruct the weld seam, and has strong applicability.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A tooling fixture for welding steering knuckles includes a base and a rotary mounting table for supporting the steering knuckles. The rotary mounting table is rotatably mounted on the base via a rotating shaft to drive the steering knuckles to rotate for multi-directional welding. The rotary mounting table is provided with a limiting component to limit and fix steering knuckles of different sizes on the rotary mounting table.

[0010] As a further improvement to the above technical solution:

[0011] The limiting assembly includes a locking screw, a pressure plate, and multiple positioning protrusions of different specifications. Each positioning protrusion can be detachably installed on a rotating mounting table by a screw to allow insertion into steering knuckles of different specifications. Each positioning protrusion has a vertical threaded hole at its top to allow the locking screw to drive the pressure plate to press and limit the steering knuckle on the rotating mounting table.

[0012] The pressure plate has an elastic layer on the side that contacts the steering knuckle, and the elastic layer is made of rubber or silicone.

[0013] The rotating mounting platform includes a fixedly connected platform and a hollow support column. The rotating shaft passes through the support column and is fixed to the base at its bottom. Bearings are provided at both the upper and lower ends of the rotating shaft for connecting with the support column so that the support column drives the platform to rotate together.

[0014] The rotating shaft has multiple limiting through holes along its circumference, and the support column has a positioning hole. The positioning hole has a limiting pin, which is inserted into the limiting through hole after the platform is rotated to the correct position so that the platform stops rotating.

[0015] A gap is provided between the bottom of the support column and the base.

[0016] The bottom of the rotating shaft is detachably mounted on the base via a connector, which includes a fixing screw that passes vertically through the base.

[0017] It is also equipped with a limit stop, which is movable and adjustable and is installed on the top surface of the rotary mounting platform. It is used to tighten the steering knuckle of different sizes by adjustment.

[0018] The top surface of the rotating mounting platform is covered with a slide rail, and the limiting block is slidably installed on the slide rail and fixed to the top surface of the rotating mounting platform by screws after sliding adjustment.

[0019] Compared with the prior art, the advantages of this utility model are:

[0020] I. This utility model discloses a tooling fixture for welding steering knuckles. By setting a rotating mounting table to support the steering knuckle and drive the steering knuckle to rotate on the base, it is applicable to both left and right steering knuckle welding directions. This makes the tooling fixture suitable for various steering knuckles with different welding directions, greatly improving the applicability of the tooling fixture. Furthermore, the rotating mounting table drives the steering knuckle to rotate on the base, which exposes the position to be welded well, making it convenient for welding equipment to weld it, greatly improving welding efficiency and quality.

[0021] II. This utility model discloses a tooling fixture for welding steering knuckles. By setting a limiting component, it limits and fixes steering knuckles of different sizes. On the one hand, it improves the connection strength between the steering knuckle and the rotary mounting table, ensuring that the steering knuckle will not shift during rotation and avoiding positional deviations caused by steering knuckle movement during welding. On the other hand, it makes the tooling fixture applicable to steering knuckles of multiple sizes, further improving the applicability of the tooling fixture.

[0022] III.

Bearings are installed at both the upper and lower ends of the rotating shaft and the support column, allowing the support column to drive the platform to rotate together. Compared to the rotating shaft driving the platform, the support column drives both the platform and the steering knuckle to rotate, while the rotating shaft remains fixed to the base. This rotational motion is more stable and reliable, avoiding excessive vibration during rotation that could affect welding quality.

[0025] VI. The present invention discloses a tooling fixture for welding steering knuckles, which has a positioning hole on the support column.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, the tooling fixture for welding steering knuckles in this embodiment includes a base 1 and a rotating mounting table 2 for supporting the steering knuckle 4. The rotating mounting table 2 is rotatably mounted on the base 1 via a rotating shaft 21 to drive the steering knuckle 4 to rotate for multi-directional welding. The rotating mounting table 2 is provided with a limiting component 3 to limit and fix steering knuckles 4 of different sizes on the rotating mounting table 2.

[0036] The specific implementation principle of the tooling fixture used for welding steering knuckles is as follows:

[0037] The tooling fixture for welding steering knuckles is used by first mounting the steering knuckle 4 on the rotary mounting table 2, and then fixing the steering knuckle 4 to the rotary mounting table 2 by the limiting component 3 to prevent displacement of the steering knuckle 4 during rotation and thus avoid welding positioning deviation. Then, the drive shaft 21 is rotated, which drives the rotary mounting table 2 and the steering knuckle 4 to rotate together, exposing the welding points in different directions, facilitating multi-directional welding of the steering knuckle 4.

[0038] Through the aforementioned special scientific design, this tooling fixture for welding steering knuckles has the following advantages:

[0039] 1. By setting a rotating mounting table 2 to support the steering knuckle 4 and drive the steering knuckle 4 to rotate on the base 1, it is applicable to both left and right welding directions of the steering knuckle 4. This makes the tooling fixture applicable to various steering knuckle 4 with different welding directions, which greatly improves the applicability of the tooling fixture. In addition, the rotating mounting table 2 drives the steering knuckle 4 to rotate on the base 1, which exposes the position to be welded well, making it convenient for welding equipment to weld it, and greatly improving welding efficiency and quality.

[0040] Second, by setting the limiting component 3 to limit and fix steering knuckles 4 of different sizes, on the one hand, the connection strength between the steering knuckle 4 and the rotary mounting table 2 is improved, ensuring that the steering knuckle 4 will not shift during rotation and avoiding positional deviation caused by the movement of the steering knuckle 4 during welding. On the other hand, this tooling fixture is applicable to steering knuckles 4 of multiple sizes, further improving the applicability of the tooling fixture.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the limiting component 3 includes a locking screw 32, a pressure plate 33, and multiple positioning protrusions 31 of different specifications. Each positioning protrusion 31 can be detachably installed on the rotary mounting table 2 by screws to allow insertion into steering knuckles 4 of different specifications. Each positioning protrusion 31 has a vertical threaded hole 311 at its top, which allows the locking screw 32 to drive the pressure plate 33 to press and limit the steering knuckle 4 onto the rotary mounting table 2. First, the steering knuckle 4 is inserted into the positioning protrusion 31. Then, the pressure plate 33 is further inserted into the positioning protrusion 31. Finally, the locking screw 32 is screwed into the vertical threaded hole 311 at the top of the positioning protrusion 31 to press and limit the steering knuckle 4 onto the rotary mounting table 2, achieving a detachable connection with high strength between the steering knuckle 4 and the rotary mounting table 2. By setting multiple positioning protrusions 31 of different specifications to accommodate steering knuckles 4 of different sizes, the applicability of the tooling fixture is greatly improved. By setting locking screws 32 and pressure plates 33 to lock the steering knuckle 4 onto the positioning protrusions 31, the connection strength between the steering knuckle 4 and the rotary mounting table 2 is greatly improved, and the welding quality is further improved.

[0042] like Figure 1 and Figure 2 As shown in this embodiment, the pressure plate 33 has an elastic layer on the side that contacts the steering knuckle 4. The elastic layer is made of rubber or silicone. By providing an elastic layer on the pressure plate 33, vibrations generated during welding are buffered, preventing uneven welds on the steering knuckle 4 and greatly improving the welding qualification rate.

[0043] like Figure 1 and Figure 2 As shown, in this embodiment, the rotating mounting platform 2 includes a fixedly connected platform plate 22 and a hollow support column 23. A rotating shaft 21 passes through the support column 23 and is fixed to the base 1 at its bottom. Bearings 5 ​​are provided at both the upper and lower ends of the rotating shaft 21 for connection with the support column 23, allowing the support column 23 to drive the platform plate 22 to rotate together. By setting the platform plate 22 to carry the steering knuckle 4, and the rotating shaft 21 passing through the hollow support column 23, with bearings 5 ​​between the upper and lower ends of the rotating shaft 21 and the support column 23, the support column 23 drives the platform plate 22 to rotate together. Compared to the rotating shaft 21 driving the platform plate 22 to rotate, the support column 23 drives the platform plate 22 and the steering knuckle 4 to rotate, while the rotating shaft 21 remains fixed to the base 1, resulting in a more stable and reliable rotational motion, avoiding excessive vibration during rotation that could affect welding quality.

[0044] like Figure 1 and Figure 2 As shown, in this embodiment, the rotating shaft 21 has multiple limiting through holes along its circumference, and the support column 23 has a positioning hole 25. A limiting pin 6 is provided in the positioning hole 25, which is used to insert into the limiting through hole after the platform 22 has rotated to the correct position, so that the platform 22 stops rotating. By providing a positioning hole 25 on the support column 23, the limiting pin 6 is inserted into the limiting through hole after the platform 22 has rotated to the correct position to limit the platform 22, thereby further improving the stability of the platform 22 during the welding of the steering knuckle 4.

[0045] like Figure 1 and Figure 2 As shown, in this embodiment, a gap is provided between the bottom of the support column 23 and the base 1. By providing a gap between the bottom of the support column 23 and the base 1 to avoid friction between the support column 23 and the base 1 hindering the rotation of the support column 23, the reliability and stability of the tooling fixture are greatly improved.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the bottom of the rotating shaft 21 is detachably mounted on the base 1 via a connector 7. The connector 7 includes a fixing screw that passes vertically through the base 1. By setting the connector 7 to allow the rotating shaft 21 to be detachably connected to the base 1 from the bottom, it is convenient to disassemble and repair the rotating shaft 21, convenient to add lubricating oil to the bearing 5 for maintenance, avoid rotational jamming, and greatly improve the reliability of the device.

[0047] like Figure 1 and Figure 2 As shown, in this embodiment, a limiting block 24 is also provided. The limiting block 24 is movably and adjustablely mounted on the top surface of the rotary mounting platform 2 and is used to adjust and abut against steering knuckles 4 of different sizes.

[0048] like Figure 1 and Figure 2 As shown in the figure, in this embodiment, a slide rail (not shown) is laid on the top surface of the rotary mounting platform 2. The limiting block 24 is slidably mounted on the slide rail and fixed to the top surface of the rotary mounting platform 2 by screws after sliding adjustment. By setting the limiting block 24, which can slide on the top surface of the rotary mounting platform 2, to abut against steering knuckles 4 of different sizes, the connection strength between the steering knuckle 4 and the rotary mounting platform 2 is further improved.

[0049] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
