Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts testing technology, and more specifically, it relates to an automatic steering knuckle deformation detection tooling and marking equipment. Background Technology
[0002] As a key component of the automotive steering axle, the quality of the steering knuckle directly affects the vehicle's driving safety and handling performance. During the manufacturing process of the steering knuckle, the marking process is an essential step, used to mark important information such as the product model and batch number.
[0003] When using a simple clamping structure to fix the steering knuckle, the complex shape of the steering knuckle and the unreasonable distribution of clamping points and difficulty in precisely controlling the clamping force of traditional tooling easily lead to clamping instability during the marking process. Once clamping is unstable, the steering knuckle will shift, and even a slight displacement deviation will cause the marking position to deviate from the design position. Inaccurate marking position will result in non-standard product appearance and seriously interfere with subsequent product traceability and quality control processes. Existing tooling lacks real-time detection methods for steering knuckle deformation, making it impossible for workers to detect deformation in time, resulting in potential quality problems in the produced steering knuckles. If steering knuckles with deformation exceeding the allowable range are produced, it will not only affect the strength and reliability of the steering knuckle, but also pose a serious threat to the safety and stability of the entire vehicle. Utility Model Content
[0004] The purpose of this invention is to provide a punching fixture that automatically detects the deformation of steering knuckles. This fixture aims to solve the problem of poor stability when clamping steering knuckles with traditional fixtures, which leads to steering knuckle displacement and deformation. It also aims to prevent steering knuckles with deformation exceeding the allowable range from leaking out, which not only affects the strength and reliability of the steering knuckle but also poses a serious threat to the safety and stability of the entire vehicle.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an automatic stamping fixture for detecting the deformation of a steering knuckle, including a working platform, wherein a bottom limiting component, a top clamping component and a displacement measuring component are provided on the working platform;
[0006] The bottom limiting component includes a longitudinal limiting member and a lateral limiting member sequentially disposed on the upper surface of the working platform. The longitudinal limiting member is used to clamp on both sides of the lower end boss of the steering knuckle to limit the longitudinal displacement of the steering knuckle. The lateral limiting member is used to clamp on both sides of the lower end boss of the steering knuckle to limit the lateral displacement of the steering knuckle.
[0007] The top clamping assembly includes a support frame disposed on the upper surface of the work platform. A top clamping member is disposed at the top of the support frame. The top clamping member is located between the longitudinal limiting member and the transverse limiting member. The top clamping member is used to clamp the upper boss of the steering knuckle on both sides.
[0008] The displacement measuring component is located on the side of the lateral limiting member away from the longitudinal limiting member. The displacement measuring component includes a mounting bracket disposed on the upper surface of the working platform. A displacement sensor for detecting the displacement of the steering knuckle is disposed on the upper surface of the mounting bracket.
[0009] In one possible implementation, the longitudinal limiting member includes a first base disposed on the upper surface of the work platform, with first blocks respectively disposed on both sides of the upper end of the first base, and a first groove formed between the two first blocks for clamping the lower end boss of the steering knuckle, and a first longitudinal limiting block for supporting the bottom of the steering knuckle is detachably disposed at the bottom of the first groove.
[0010] In one possible implementation, a positioning hole is provided laterally within any of the first blocks, and a positioning pin is inserted into the positioning hole to position the steering knuckle.
[0011] In one possible implementation, a first transverse through groove is provided at the bottom of the first groove, a first mounting block is detachably installed in the first transverse through groove, and a first longitudinal limiting block is fixedly disposed on the upper end surface of the first mounting block.
[0012] In one possible implementation, the lateral limiting member includes a second base disposed on the upper surface of the work platform, with second blocks respectively disposed on both sides of the upper end of the second base, and a second groove formed between the two second blocks, and a detachable lateral limiting block for supporting the side wall of the steering knuckle is provided.
[0013] In one possible implementation, a longitudinal through groove is formed on the inner wall of either side of the second groove, and a second mounting block is detachably installed in the longitudinal through groove. The transverse limiting block is fixedly disposed on the upper end face of the second mounting block.
[0014] In one possible implementation, the top clamping member includes a mounting beam fixed to the top of the support frame, one end of the mounting beam having a fixed end head, and the other end of the mounting beam having a movable latch that presses or releases the upper boss of the steering knuckle.
[0015] In one possible implementation, the bottom limiting component further includes a pre-limiting member located between the longitudinal limiting member and the transverse limiting member;
[0016] The pre-limiting component includes a third base disposed on the upper surface of the work platform. The upper ends of the third base are respectively slidably disposed on both sides of the third base. A third groove is formed between the two third blocks for pre-clamping the lower end boss of the steering knuckle. A second longitudinal limiting block is detachably disposed at the bottom of the third groove.
[0017] In one possible implementation, a second transverse through groove is provided at the bottom of the third groove, a third mounting block is detachably installed in the second transverse through groove, and the second longitudinal limiting block is fixedly disposed on the upper end face of the third mounting block.
[0018] The beneficial effects of the engraving fixture for automatically detecting steering knuckle deformation provided by this utility model are as follows: The longitudinal and transverse limiting components in the bottom limiting assembly clamp the lower end boss of the steering knuckle from the longitudinal and transverse directions, forming a stable planar limiting structure. This accurately limits the longitudinal and transverse displacement of the steering knuckle, significantly reducing the slippage of the steering knuckle on the work platform compared to the single-direction limiting of traditional fixtures. The top clamping component of the top clamping assembly presses the upper end boss of the steering knuckle vertically, forming a three-dimensional clamping system with the bottom limiting component. This further prevents the steering knuckle from shifting up and down or tilting during engraving, ensuring its stable fixation in three-dimensional space. The displacement sensor installed on the work platform can detect the displacement of the steering knuckle in real time. Before and during the engraving process, the sensor continuously monitors the surface displacement data of the steering knuckle. Once the deformation exceeds the preset threshold, the tooling integrated control system can automatically adjust the pressure of the top clamping part or adjust the engraving equipment parameters, such as reducing the engraving speed and reducing the impact force, to achieve closed-loop management of "detection-feedback-control". This prevents the steering knuckle with deformation exceeding the allowable range from flowing out, avoids affecting the strength and reliability of the steering knuckle, and ensures the safety and stability of the entire vehicle.
[0019] This utility model also provides a marking device, including the marking fixture for automatically detecting the deformation of the steering knuckle.
[0020] The beneficial effect of the marking equipment provided by this utility model is that: the marking equipment uses the above-mentioned automatic steering knuckle deformation detection marking fixture, and therefore has the same beneficial effect as the above-mentioned automatic steering knuckle deformation detection marking fixture.

[0039] Please see Figures 1 to 7 This invention provides an automatic steering knuckle deformation detection tooling. The tooling includes a work platform 100, on which a bottom limiting component, a top clamping component, and a displacement measuring component 600 are mounted. The bottom limiting component includes a longitudinal limiting member 200 and a transverse limiting member 300 sequentially disposed on the upper surface of the work platform 100. The longitudinal limiting member 200 clamps the lower end boss of the steering knuckle on both sides to limit its longitudinal displacement, and the transverse limiting member 300 clamps the lower end boss of the steering knuckle on both sides to limit its transverse displacement. The top clamping component includes a bottom limiting component 200 and a top clamping component 300 disposed on the upper surface of the work platform 100. The upper surface of the work platform 100 has a support frame 130, and the top of the support frame 130 is provided with a top clamping member 400. The top clamping member 400 is located between the longitudinal limiting member 200 and the lateral limiting member 300, and is used to clamp the upper boss of the steering knuckle on both sides. The displacement measuring component 600 is located on the side of the lateral limiting member 300 away from the longitudinal limiting member 200. The displacement measuring component 600 includes a mounting frame 610 provided on the upper surface of the work platform 100, and a displacement sensor 620 for detecting the displacement of the steering knuckle is provided on the upper surface of the mounting frame 610.
[0040] This utility model provides an automatic steering knuckle deformation detection tooling. Compared with the prior art, the longitudinal limiting member 200 and the transverse limiting member 300 in the bottom limiting assembly clamp the lower end boss of the steering knuckle from the longitudinal and transverse directions, forming a stable planar limiting structure. This can accurately limit the longitudinal and transverse displacement of the steering knuckle, greatly reducing the slippage of the steering knuckle on the working platform 100 compared with the single-direction limiting of traditional tooling. The top clamping member 400 of the top clamping assembly presses the upper end boss of the steering knuckle vertically, forming a three-dimensional clamping system with the bottom limiting member, further preventing the steering knuckle from moving up and down or tilting during engraving, ensuring its stable fixation in three-dimensional space. The displacement sensor 620 installed on the work platform 100 can detect the displacement of the steering knuckle in real time. Before and during the engraving process, the sensor continuously monitors the surface displacement data of the steering knuckle. Once the deformation exceeds the preset threshold, the tooling integrated control system can automatically adjust the pressure of the top clamping part 400 or adjust the engraving equipment parameters, such as reducing the engraving speed and reducing the impact force, to achieve closed-loop management of "detection-feedback-control". This prevents the steering knuckle with deformation exceeding the allowable range from flowing out, avoids affecting the strength and reliability of the steering knuckle, and ensures the safety and stability of the entire vehicle.
[0041] Please see Figure 1 and Figure 2 The first base 210 is installed on the working platform 100. The first groove 230 formed by the first blocks 220 on both sides can accurately fit the shape of the lower boss of the steering knuckle, and clamp the steering knuckle longitudinally from both sides, effectively restricting its forward and backward movement, ensuring that the steering knuckle maintains a stable longitudinal position during the marking process, and avoiding marking misalignment caused by longitudinal displacement.
[0042] The detachable first longitudinal limiting block 270 at the bottom of the first groove 230 further enhances the practicality and flexibility of the tooling. On the one hand, by replacing the first longitudinal limiting block 270 with different thicknesses and shapes, it can adapt to the bottom structure of various specifications of steering knuckles, meeting the limiting requirements of different vehicle models and steering knuckles of different sizes, reducing the cost for companies to change tooling due to differences in steering knuckle models. On the other hand, the detachable design facilitates individual maintenance and replacement of the limiting block. When the limiting block wears out due to long-term use, it can be quickly replaced without disassembling the entire longitudinal limiting component 200, effectively shortening equipment downtime for maintenance and improving production efficiency. In addition, the supporting effect of the first longitudinal limiting block 270 on the bottom of the steering knuckle, together with the clamping force on both sides of the first groove 230, forms a stable force system, enhancing the fixing strength of the steering knuckle in the longitudinal direction and providing a more reliable stability guarantee for the engraving operation.
[0043] Among them, after the positioning pin is inserted into the positioning hole 240 of the first block 220, it can be accurately engaged in the corresponding position of the steering knuckle, realizing the absolute positioning of the steering knuckle in the longitudinal direction, avoiding the slight displacement caused by force during the engraving process, ensuring the positional accuracy of the steering knuckle in three-dimensional space, thereby effectively improving the accuracy and consistency of the engraving marks.
[0044] The elastic layer 221 (made of materials such as rubber or silicone) on the inner wall of the first block 220, which does not have positioning holes 240, provides flexible clamping protection for the steering knuckle. On the one hand, the elastic layer 221 can closely fit the surface of the steering knuckle, filling the gaps caused by dimensional tolerances or surface unevenness of the steering knuckle, enhancing the tightness and stability of the clamping. On the other hand, when clamping force is applied, the elastic layer 221 can buffer the pressure through its own deformation, avoiding damage such as indentations and scratches to the surface of the steering knuckle caused by rigid clamping, effectively protecting the appearance and performance of the steering knuckle. The combination of these two aspects ensures the accuracy of steering knuckle positioning while also protecting the parts, significantly improving the reliability and practicality of the engraving fixture, and meeting the high-precision and high-quality production requirements of automotive parts.
[0045] The combined design of the first transverse through groove 250 at the bottom of the first groove 230 and the first mounting block 260 brings greater flexibility and adaptability to the limiting support of the steering knuckle. The presence of the first transverse through groove 250 allows the first mounting block 260 to be adjusted laterally within the groove, and the first longitudinal limiting block 270 fixed on the mounting block can also be flexibly adjusted accordingly. This feature allows the tooling to accurately adapt to the bottom shape and installation requirements of steering knuckles of different sizes and structures. When producing different models of steering knuckles, companies do not need to replace the entire longitudinal limiting component 200; they can achieve stable support and positioning for different steering knuckles simply by adjusting the position of the first mounting block 260 within the through groove, greatly reducing equipment modification costs and debugging time.
[0046] Meanwhile, the detachable nature of the first mounting block 260 facilitates routine maintenance and component replacement. When the first longitudinal limiting block 270 wears out, or when it needs to be replaced with a limiting block adapted to other steering knuckle specifications, the first mounting block 260 can be directly disassembled for operation, avoiding the cumbersome process of disassembling the entire longitudinal limiting component 200 and improving equipment maintenance efficiency. In addition, this modular design also makes the tooling more scalable in subsequent upgrades and modifications, allowing for convenient replacement or addition of new limiting components according to the optimization needs of the production process, further enhancing the versatility and service life of the engraving tooling.
[0047] Please see Figure 1 and Figure 3The lateral limiting component 300 includes a second base 310 disposed on the upper surface of the working platform 100. Second blocks 320 are respectively disposed on both sides of the upper end of the second base 310, forming a second groove 330 between the two second blocks 320. A detachable lateral limiting block 360 for supporting the sidewall of the steering knuckle is also provided. It can precisely conform to the lateral contour of the lower boss of the steering knuckle, applying a stable clamping force to the steering knuckle from both sides, effectively limiting its lateral displacement. Working in conjunction with the longitudinal limiting component 200, it further strengthens the planar fixation effect of the steering knuckle on the working platform 100, ensuring that the steering knuckle does not shift laterally during the marking process, laying the foundation for high-precision marking.
[0048] The detachable lateral stop block 360 design greatly enhances the versatility and flexibility of the tooling. By replacing the lateral stop block 360 with different specifications and shapes, it can adapt to the side wall structure of various steering knuckle models, meeting the diverse production needs of automotive parts and reducing the cost of frequent tooling changes due to product model variations. Furthermore, when the lateral stop block 360 wears out due to long-term use, it can be quickly disassembled and replaced without the need for complex disassembly of the entire lateral stop component 300, shortening equipment downtime for maintenance and improving production efficiency. In addition, this modular design facilitates personalized modifications or upgrades to the lateral stop block 360 according to actual production needs, enhancing the tooling's adaptability to different working conditions and providing reliable assurance for stable stamping of the steering knuckle.
[0049] A longitudinal through groove 340 is formed on the inner wall of either side of the second groove 330. A second mounting block 350 is detachably installed within the longitudinal through groove 340, and a lateral limiting block 360 is fixedly mounted on the upper surface of the second mounting block 350. This provides more precise adjustment and greater usability for the lateral limiting function. The presence of the longitudinal through groove 340 allows the second mounting block 350 to move flexibly in the vertical direction, thereby driving the lateral limiting block 360 fixed thereon to adjust its longitudinal position. This feature allows the fixture to precisely adapt to steering knuckles of different heights and sidewall structures. Whether it is a low, flat steering knuckle or a high-convex, complex model, the position of the second mounting block 350 within the through groove can be adjusted to ensure a tight fit between the lateral limiting block 360 and the steering knuckle sidewall, enhancing the stability and accuracy of lateral clamping. This effectively avoids steering knuckle wobbling caused by improper limiting height, providing more reliable positioning assurance for engraving operations.
[0050] The detachable second mounting block 350 greatly facilitates the maintenance and upgrading of the tooling. When the lateral limit block 360 wears out or needs to be replaced with a different size limit block, the operator does not need to disassemble the entire lateral limit component 300. They only need to remove the second mounting block 350 from the longitudinal through slot 340 to quickly replace the component, significantly shortening equipment maintenance time and reducing maintenance costs. At the same time, this modular design also allows for the expansion of tooling functions. Enterprises can add sensors, buffer devices, and other accessories to the second mounting block 350 according to production process improvement needs, further optimizing the limiting effect, improving the intelligence and professionalism of the engraving tooling, and adapting to the ever-evolving production requirements of the automotive parts manufacturing industry.
[0051] Please see Figure 1 and Figure 4 The top clamping component 400 includes a mounting beam 410 fixed to the top of the support frame 130. One end of the mounting beam 410 is provided with a fixed end head 420, and the other end of the mounting beam 410 is rotatably provided with a movable locking buckle 430 for pressing or releasing the upper boss of the steering knuckle. The fixed end head 420 at one end of the mounting beam 410 and the movable locking buckle 430 at the other end form a cooperating mode. During operation, the operator only needs to rotate the movable locking buckle 430 to quickly press or release the upper boss of the steering knuckle. Compared with traditional bolt fastening methods, this significantly shortens the clamping time of the steering knuckle and significantly improves production efficiency. At the same time, the rotating structure design of the movable locking buckle 430 makes the clamping process more labor-saving and reduces the labor intensity of workers.
[0052] Furthermore, after the movable latch 430 presses against the upper boss of the steering knuckle, it works in conjunction with the bottom limiting component and the lateral limiting component to construct a comprehensive three-dimensional clamping system, firmly fixing the steering knuckle to the working platform 100. This effectively prevents the steering knuckle from shifting up and down or tilting due to external forces during the engraving process, ensuring precise positioning of the steering knuckle in three-dimensional space. This stable clamping effect effectively avoids problems such as marking offset and blurring caused by steering knuckle shaking, thereby ensuring the consistency and reliability of engraving quality and meeting the stringent requirements of high-precision machining of automotive parts. In addition, the combination structure of the fixed end 420 and the movable latch 430 is simple and reliable, easy to maintain and repair, reduces equipment maintenance costs, and extends the service life of the tooling.
[0053] Please see Figure 1 and Figure 5The bottom limiting assembly also includes a pre-limiting component 500, located between the longitudinal limiting component 200 and the lateral limiting component 300. The pre-limiting component 500 includes a third base 510 disposed on the upper surface of the working platform 100. Two third blocks 520 are slidably disposed on opposite sides of the upper end of the third base 510, forming a third groove 530 between the two third blocks 520 for pre-clamping the lower end boss of the steering knuckle. A second longitudinal limiting block 560 is detachably disposed at the bottom of the third groove 530. The addition of the pre-limiting component 500 further optimizes the steering knuckle positioning process, demonstrating unique advantages in improving assembly efficiency and positioning accuracy. The pre-limiting component 500, located between the longitudinal limiting component 200 and the lateral limiting component 300, forms the third groove 530 through the relatively slidable third blocks 520 on the third base 510, enabling rapid initial clamping and fixation of the lower end boss of the steering knuckle. This pre-clamping function greatly simplifies the steering knuckle clamping process. Operators only need to place the steering knuckle in the third groove 530 and use the sliding adjustment function of the third block 520 to achieve quick positioning without repeatedly adjusting the steering knuckle position. This significantly shortens the clamping time of a single workpiece and improves the overall efficiency of the production line.
[0054] Meanwhile, the detachable second longitudinal limiting block 560 at the bottom of the third groove 530 complements the first longitudinal limiting block 270 in the longitudinal limiting component 200. The second longitudinal limiting block 560 can be quickly replaced with a suitable specification according to the bottom structure characteristics of different steering knuckles, not only enhancing the stability of the pre-limiting but also providing a reliable foundation for the precise positioning of the subsequent longitudinal and lateral limiting components 300. The pre-limiting component 500 provides initial constraint on the steering knuckle, reducing the difficulty of adjusting the longitudinal and lateral limiting components 300 during final positioning, reducing the number of repeated adjustments caused by initial position deviations of the steering knuckle, and further improving positioning accuracy. Furthermore, the modular design of the pre-limiting component 500 facilitates daily maintenance and upgrades. When the third block 520 or the second longitudinal limiting block 560 wears out, it can be quickly disassembled and replaced, ensuring that the tooling always maintains a highly efficient and stable working state, providing strong support for the continuity and reliability of steering knuckle engraving operations.
[0055] The bottom of the third groove 530 has a second transverse through groove 540, within which a third mounting block 550 is detachably installed. A second longitudinal limiting block 560 is fixedly mounted on the upper surface of the third mounting block 550. The combined design of the second transverse through groove 540 and the third mounting block 550 at the bottom of the third groove 530 further enhances the flexibility and adaptability of the pre-limiting component 500, providing a solid guarantee for the efficient and precise positioning of the steering knuckle. The second transverse through groove 540 allows the third mounting block 550 to be freely adjusted in the transverse direction, enabling the second longitudinal limiting block 560 fixed thereon to flexibly adapt to the bottom structure of steering knuckles of different sizes. Whether it is a steering knuckle model with a large width difference or a special workpiece with an irregular bottom shape, the position of the third mounting block 550 within the through groove can be adjusted to ensure that the second longitudinal limiting block 560 precisely fits the bottom of the steering knuckle, enhancing the stability and accuracy of the pre-limiting and laying a good foundation for the subsequent precise clamping of the longitudinal and transverse limiting components 300.
[0056] The detachable third mounting block 550 design offers significant advantages in tooling maintenance and upgrades. When the second longitudinal limiting block 560 wears down due to long-term use, or when it needs to be replaced with a limiting block adapted to different steering knuckle sizes, operators do not need to disassemble the entire pre-limiting component 500. They can simply remove the third mounting block 550 from the second transverse through slot 540 to quickly replace the component, significantly shortening equipment maintenance time and reducing maintenance costs. Furthermore, this modular design creates conditions for expanding the pre-limiting function. Enterprises can add auxiliary positioning devices, sensors, and other accessories to the third mounting block 550 according to actual production needs, further optimizing the pre-limiting effect, improving the intelligence and specialization of the tooling, and better adapting it to the increasingly diverse production needs of the automotive parts manufacturing industry.
[0057] In addition, the third block 520 has an L-shaped structure with a strip hole 570 on it that connects to the third base 510, so as to facilitate the adjustment of the position between the two third blocks 520, i.e. the width of the third groove 530, to accommodate different models of steering knuckles.
[0058] Please see Figure 1The work platform 100 has multiple mounting holes 110 arranged in an array. On adjacent sides of the work platform 100, the mounting holes 110 in the same column and row are marked with numerical identifiers 120. The arrayed mounting holes 110 on the work platform 100, in conjunction with the numerical identifiers 120 on adjacent sides, provide a significant advantage for the engraving fixture that automatically detects steering knuckle deformation. The array design of the mounting holes 110 gives the fixture high flexibility; components such as the bottom limiting component and the top clamping component 400 can be quickly installed in any hole position using bolts without customized processing. This is particularly suitable for multi-variety, small-batch production scenarios, quickly adapting to the size differences of steering knuckles in different vehicle models, accurately locating component installation positions, eliminating manual measurement and repeated adjustments, and significantly improving production line changeover efficiency.
[0059] Furthermore, the mounting holes 110 are set at fixed standard intervals, combined with the quantitative guidance of the digital markings 120, avoiding reading errors caused by traditional ruler markings. This ensures stable positioning of the steering knuckle during the engraving process and effectively reduces quality issues such as marking offset and blurring. In addition, the hole combinations of tooling components corresponding to different products can be recorded as standardized process documents, facilitating direct reference in subsequent production. This enables traceability of process parameters and avoids inconsistencies in positioning due to differences in operator experience, providing a reliable guarantee for high-precision engraving and stable quality of the steering knuckle.
[0060] Based on the same inventive concept, this utility model also provides a marking device. This marking device uses the aforementioned automatic steering knuckle deformation detection marking fixture. The marking device also includes a data processing unit, a display unit, and a marking system. The data processing unit receives and analyzes the signal sent by the displacement sensor 620 to determine whether the steering knuckle has deformed. The result is displayed on the display unit, indicating whether the corresponding steering knuckle is a qualified or defective product. Qualified products are marked with a traceability code, while defective products trigger an alarm. This marking device, by integrating the automatic steering knuckle deformation detection marking fixture with an intelligent control system, constructs a highly efficient and precise quality control system, offering significant advantages in improving production efficiency, ensuring product quality, and reducing labor costs.
[0061] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
