Description

Technical Field

[0001] This utility model relates to the field of steering knuckle processing technology, and in particular to a steering knuckle processing anti-deformation fixture. Background Technology

[0002] The steering knuckle, also known as the "steering knuckle," is one of the important components of the automotive steering axle. It enables the car to drive stably and transmits driving direction sensitively. The function of the steering knuckle is to transmit and bear the load of the front of the car, support and drive the front wheels to rotate around the kingpin so that the car can be steered.

[0003] During the production process, the steering knuckle 1 corresponding to this application is as follows: Figure 1 As shown, the steering knuckle 1 includes a flange 11 and a support journal 12. The support journal 12 is located at the upper end of the flange 11. The flange 11 has a set of mounting holes 110, which are spaced apart on the flange 11. The shaft hole 10 is located at the end of the support journal 12 away from the flange 11. Due to its structural characteristics, the steering knuckle 1 is prone to elastic or plastic deformation during the machining of the shaft hole 10, especially due to the cutting force generated during drilling and the improper pressure applied during clamping (such as the flange 11 flatness exceeding the tolerance, i.e., warping, or the support journal 12 bending). This results in substandard product quality, requiring rework or scrapping, and increasing production costs. Therefore, a steering knuckle machining anti-deformation fixture is urgently needed to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides a steering knuckle machining anti-deformation fixture, which solves the technical problem that the steering knuckle is prone to deformation and has a low machining pass rate when machining shaft holes in existing steering knuckles.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A steering knuckle machining anti-deformation fixture is used to machine a shaft hole on the steering knuckle. The steering knuckle includes: a flange and a support journal. The support journal is located at the upper end of the flange. The flange has a set of mounting holes spaced apart. The shaft hole is located at the end of the support journal away from the flange. A workbench, wherein the workbench is provided with: A movable plate, wherein the movable plate is vertically movable and adjustable; A loading assembly is mounted on a movable plate. The loading assembly includes a loading seat and a set of limiting posts. The loading seat is floating and is used to support the flange. The set of limiting posts is configured to correspond one-to-one with a set of mounting holes. A drilling assembly, the drilling assembly comprising: a drill bit, the size of which is adapted to the shaft hole; An adjustment mechanism is provided for adjusting the position of the drill bit in the horizontal and vertical directions.

[0006] Based on the above structure, the principle of the steering knuckle machining anti-deformation fixture is as follows: When needed, firstly, the flange is placed on the carrier, which floats and supports the flange to ensure uniform contact. A set of limiting pins are inserted into the corresponding set of mounting holes to complete the horizontal positioning of the steering knuckle, preventing the drilling position from shifting due to steering knuckle displacement during machining. Then, according to the length of the support journal and the position of the shaft hole to be machined, the position of the moving plate is adjusted so that the end of the support journal to be machined is within a height range convenient for the drill bit to machine. Subsequently, the position of the drill bit is adjusted by the adjusting mechanism so that the drill bit is directly opposite the preset position of the shaft hole on the support journal, ensuring that the axis of the drill bit is aligned with the theoretical axis of the shaft hole. The drill bit is then moved down close to the support journal. The surface to be machined is used as the starting position for the shaft hole. Next, the drilling assembly is started, causing the drill bit to rotate and move vertically downward at a preset feed rate to cut the support journal and machine a shaft hole that matches the design size. After the shaft hole is machined, the drilling assembly is closed, the drill bit is reset to its initial position, and the steering knuckle is removed from the carrier to complete the machining. The floating carrier evenly supports the flange, avoiding steering knuckle deformation (such as flange warping and support journal bending) caused by contact stress concentration in traditional rigid supports, thus improving the machining qualification rate of the steering knuckle. The vertical adjustment of the moving plate and the multi-directional adjustment of the adjustment mechanism can adapt to the machining of steering knuckles of different sizes, improve the versatility of the fixture, and reduce production costs.

[0007] Furthermore, in this application, a steering knuckle machining anti-deformation fixture is provided between the worktable and the movable plate: an adjustment component is provided, the adjustment component includes: a sliding plate and a driving device, the sliding plate is slidably mounted on the worktable, the sliding plate is movable and adjustable in the X direction, the driving device is mounted on the worktable, the movable end of the driving device is connected to the sliding plate, a pair of pressure blocks are provided on the sliding plate, the pair of pressure blocks slide against the sliding plate at intervals in the Y direction, the contact points of the sliding plate and the pressure blocks are provided with inclined surfaces, when the sliding plate moves in the X direction, the pair of pressure blocks move in the vertical direction, and the movable plate is mounted on the pair of sliding plates. As a preferred embodiment of this application, a steering knuckle machining anti-deformation fixture is provided. When the moving plate needs to be adjusted in the vertical position, the sliding plate moves along the X direction under the action of the drive device. Since the contact points between the sliding plate and a pair of pressure blocks are both inclined surfaces, the X-direction movement of the sliding plate can be converted into the vertical movement of the pressure blocks using the inclined plane transmission principle. The moving plate is mounted on a pair of pressure blocks, thereby realizing the vertical height adjustment of the moving plate to adapt to the machining height requirements of different support journals. The pair of pressure blocks are spaced apart in the Y direction to jointly support the moving plate, which can form a stable support for the moving plate and effectively suppress the shaking or tilting that may occur during the machining process, ensuring the stability of the moving plate, the load-bearing components above it, and the steering knuckle.

[0008] Furthermore, in a steering knuckle machining anti-deformation fixture of this application, the adjusting component further includes: two sets of guide posts, the two sets of guide posts being spaced apart in the Y direction, the sliding plate being located between the two sets of guide posts, and a pair of pressure blocks respectively sleeved on the two sets of guide posts. As a preferred embodiment of this application, in a steering knuckle machining anti-deformation fixture, the guide posts are used to constrain the movement trajectory of the pressure blocks, ensuring that the pressure blocks can only move vertically, preventing them from shifting in the Y direction due to the force of the inclined surface during the process of transitioning from X-direction movement with the sliding plate to vertical movement, thus ensuring the stability of the pressure block's vertical movement.

[0009] Furthermore, in this application, a steering knuckle machining anti-deformation fixture is provided at the upper end of the moving plate: a cover plate is provided, each of the pressure blocks is provided with a pair of top posts, the pair of top posts are installed on the pressure blocks at intervals in the X direction, the cover plate is installed on the top posts, the cover plate is sleeved on the load seat and the limiting post, the load seat includes: a receiving cavity, the receiving cavity is provided with an elastic element, the end of the elastic element away from the load seat abuts against the moving plate, the outer side wall of the load seat is provided with a limiting part, the limiting part is provided along the radial direction of the load seat, and the limiting part is located between the moving plate and the cover plate. As a preferred embodiment of this application, a steering knuckle machining anti-deformation fixture includes a top column support cover plate that rises and falls synchronously with the pressure block to ensure balanced force transmission. An elastic element provides elastic support for the load seat, enabling it to float more flexibly and better adapt to the flange shape. During machining, it absorbs and buffers vibrations generated by drill bit cutting, reducing the impact of vibration on the steering knuckle machining accuracy and minimizing damage to the fixture itself. When the load seat floats upward, the limiting part abuts against the lower end of the cover plate, limiting the maximum upward float of the load seat. When the load seat moves downward, it abuts against the upper end of the moving plate, limiting its maximum downward movement, thus ensuring the load seat's float is within a reasonable range. Simultaneously, during the load seat's float, it helps maintain the load seat's posture, reducing the possibility of tilting. The cover plate also prevents the intrusion of debris and oil, keeping key parts of the load assembly and adjustment assembly clean, reducing component wear and failure rates, and lowering maintenance costs.

[0010] Furthermore, in a steering knuckle machining anti-deformation fixture of this application, the movable plate is provided with a limiting recess, which is used to accommodate the end of the elastic element away from the load seat. As a preferred embodiment of this application, the limiting recess of the steering knuckle machining anti-deformation fixture provides a accommodating space for the end of the elastic element away from the load seat, which can limit the displacement of the elastic element in the horizontal direction, prevent it from shifting, tilting or falling off during compression or rebound, ensure that its elastic support force on the load seat is uniform and stable, so that the load seat can more reliably fit the flange, further reduce local stress concentration caused by unstable support, and reduce the risk of steering knuckle deformation.

[0011] Furthermore, in a steering knuckle machining anti-deformation fixture of this application, the drilling assembly further includes: a mounting part and a rotation drive device. The mounting part is mounted on an adjustment mechanism, the rotation drive device is mounted on the mounting part, and the drill bit is mounted on the rotating end of the rotation drive device. As a preferred embodiment of this application, in a steering knuckle machining anti-deformation fixture, the mounting part stably mounts the rotation drive device and the drill bit on the adjustment mechanism, reducing vibration and displacement caused by loose components during drilling, making the rotation and feed of the drill bit smoother, which is beneficial to ensuring the machining accuracy of the shaft hole and reducing dimensional errors caused by vibration.

[0012] Furthermore, in this application, a steering knuckle machining anti-deformation fixture includes an adjustment mechanism comprising: a mounting frame, an X-axis moving component, and a vertical moving component. The mounting frame is mounted on a workbench. The X-axis moving component includes: a first sliding plate and a first linear drive device. The first sliding plate is slidably mounted on the mounting frame via a first slide rail. The first linear drive device is mounted on the mounting frame, and its movable end is connected to the first sliding plate. The vertical moving component includes: a mounting column and a second linear drive device. The mounting column is slidably mounted on the first sliding plate via a second slide rail. The second linear drive device is mounted on the first sliding plate and is used to drive the mounting column to move vertically. The mounting part is mounted on the end of the mounting column near the workbench. As a preferred embodiment of this application, a steering knuckle machining anti-deformation fixture is provided. In the X-axis moving assembly, a first linear drive device drives a first slide plate to slide along a first slide rail on a mounting bracket, thereby driving the vertical moving assembly and the drilling assembly to move synchronously along the X-axis, realizing the adjustment of the drill bit's position in the X-axis. In the vertical moving assembly, a second linear drive device drives a mounting column to slide vertically along a second slide rail on a first slide plate, directly driving the mounting part of the drilling assembly and the drill bit to move up and down, thereby realizing the adjustment of the drill bit's vertical position (such as drilling depth, initial cutting position) to meet the machining requirements of different shaft hole depths.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: The purpose of this invention is to provide a steering knuckle machining anti-deformation fixture. By setting a floating support seat to evenly support the steering knuckle flange, the contact stress concentration caused by traditional rigid support is avoided, thereby preventing the steering knuckle from deforming during machining. At the same time, the vertical adjustment structure of the moving plate and the adjustment mechanism allow for multi-directional position adjustment of the drill bit, adapting to the machining requirements of steering knuckles of different sizes and improving the versatility of the fixture. In addition, the inclined plane transmission of the sliding plate and the pressure block in the adjustment assembly, the constraint of the guide column, and the cooperation of the cover plate and the limiting part enhance the stability of the fixture during machining, reduce the impact of vibration on machining accuracy, thereby improving the machining pass rate of steering knuckles and reducing production costs.

Detailed Implementation

[0016] like Figure 2As shown, a steering knuckle machining anti-deformation fixture is used to machine a shaft hole 10 on a steering knuckle 1. The steering knuckle 1 includes: a flange 11 and a support journal 12. The support journal 12 is located at the upper end of the flange 11. The flange 11 has a set of mounting holes 110, which are spaced apart on the flange 11. The shaft hole 10 is located at the end of the support journal 12 away from the flange 11. Workbench 2, wherein the workbench 2 is provided with: The movable plate 3 is vertically movable and adjustable. The loading assembly 4 is mounted on the moving plate 3. The loading assembly 4 includes a loading seat 41 and a set of limiting posts 42. The loading seat 41 is floating and is used to support the flange 11. The set of limiting posts 42 is configured to correspond one-to-one with a set of mounting holes 110. Drilling assembly 5, the drilling assembly 5 including: drill bit 51, the size of the drill bit 51 being adapted to the shaft hole 10; Adjustment mechanism 6 is used to adjust the position of drill bit 51 in the horizontal and vertical directions.

[0017] Based on the above structure, the principle of the steering knuckle machining anti-deformation fixture is as follows: When needed, firstly, the flange 11 is placed on the carrier 41, and the carrier 41 floats to support the flange 11, ensuring uniform contact. A set of limiting pins 42 are inserted into the corresponding set of mounting holes 110 to complete the horizontal positioning of the steering knuckle 1, avoiding displacement of the drilling position due to the displacement of the steering knuckle 1 during machining. Then, according to the length of the support journal 12 and the position of the shaft hole 10 to be machined, the position of the moving plate 3 is adjusted so that the end of the support journal 12 to be machined is within the height range that is convenient for the drill bit 51 to machine. Subsequently, the position of the drill bit 51 is adjusted by the adjusting mechanism 6 so that the drill bit 51 is directly opposite the preset position of the shaft hole 10 on the support journal 12, ensuring that the axis of the drill bit 51 is aligned with the theoretical axis of the shaft hole 10. The drill bit 51 is then moved down to a position close to the target position. The surface to be machined on the support journal 12 serves as the starting position for the shaft hole 10. Next, the drilling assembly 5 is activated, causing the drill bit 51 to rotate and move vertically downwards at a preset feed rate to cut the support journal 12, producing a shaft hole 10 that matches the design dimensions. After the shaft hole 10 is machined, the drilling assembly 5 is closed, allowing the drill bit 51 to return to its initial position. The steering knuckle 1 is then removed from the carrier 41, completing the machining process. The floating carrier 41, by evenly supporting the flange 11, avoids the deformation of the steering knuckle 1 caused by stress concentration in traditional rigid supports (such as warping of the flange 11 or bending of the support journal 12), thus improving the machining pass rate of the steering knuckle 1. The vertical adjustment of the moving plate 3 and the multi-directional adjustment of the adjustment mechanism 6 can adapt to the machining of steering knuckles 1 of different sizes, improving the versatility of the fixture and reducing production costs. There are two mounting holes 110, and correspondingly, there are also two limiting posts 42.

[0018] In this embodiment, an adjustment component 7 is provided between the workbench 2 and the movable plate 3. The adjustment component 7 includes a sliding plate 71 and a driving device 72. The sliding plate 71 is slidably mounted on the workbench 2 and is movable and adjustable in the X direction. The driving device 72 is mounted on the workbench 2, and the movable end of the driving device 72 is connected to the sliding plate 71. A pair of pressure blocks 73 are provided on the sliding plate 71. The pair of pressure blocks 73 slide and abut against the sliding plate 71 at intervals in the Y direction. The contact points of the sliding plate 71 and the pressure blocks 73 are provided with inclined surfaces. When the sliding plate 71 moves in the X direction, the pair of pressure blocks 73 move in the vertical direction. The movable plate 3 is mounted on the pair of sliding plates 71. When the vertical position of the movable plate 3 needs to be adjusted, as the slide plate 71 moves along the X-direction under the action of the drive device 72, since the contact points between the slide plate 71 and the pair of pressure blocks 73 are both inclined surfaces, the X-direction movement of the slide plate 71 can be converted into the vertical movement of the pressure blocks 73 using the principle of inclined plane transmission. The movable plate 3 is mounted on the pair of pressure blocks 73, thereby realizing the vertical height adjustment of the movable plate 3 to adapt to the processing height requirements of different support journals 12. The pair of pressure blocks 73 are spaced apart in the Y-direction to jointly support the movable plate 3, which can form a stable support for the movable plate 3, effectively suppressing the shaking or tilting of the movable plate 3 that may occur during processing, and ensuring the stability of the movable plate 3 and the upper load assembly 4 and steering knuckle 1. The drive device 72 uses a cylinder.

[0019] In this embodiment, as Figure 3 , 4 As shown, the adjustment assembly 7 further includes: two sets of guide posts 74, which are spaced apart in the Y direction. The slide plate 71 is located between the two sets of guide posts 74, and a pair of pressure blocks 73 are respectively fitted onto the two sets of guide posts 74. The guide posts 74 are used to constrain the movement trajectory of the pressure blocks 73, ensuring that the pressure blocks 73 can only move vertically. This prevents the pressure blocks 73 from shifting in the Y direction due to the force of the inclined surface during the transition from X-direction movement to vertical movement with the slide plate 71, thus ensuring the stability of the vertical movement of the pressure blocks 73. There are two guide posts 74 in each set.

[0020] In this embodiment, the upper end of the moving plate 3 is provided with a cover plate 8. Each pressure block 73 is provided with a pair of top posts 731. The pair of top posts 731 are installed on the pressure block 73 at intervals in the X direction. The cover plate 8 is installed on the top posts 731. The cover plate 8 is sleeved on the carrier 41 and the limiting post 42. The carrier 41 includes a receiving cavity 410. The receiving cavity 410 is provided with an elastic element 411. The end of the elastic element 411 away from the carrier 41 abuts against the moving plate 3. The outer side wall of the carrier 41 is provided with a limiting part 412. The limiting part 412 extends radially along the carrier 41 and is located between the moving plate 3 and the cover plate 8. The top column 731 supports the cover plate 8 and rises and falls synchronously with the pressure block 73 to ensure balanced force transmission. The elastic element 411 provides elastic support for the carrier 41, enabling the carrier 41 to float more flexibly and better adapt to the shape of the flange 11. During processing, it can absorb and buffer the vibration generated by the drill bit 51 cutting, reducing the impact of vibration on the machining accuracy of the steering knuckle 1, and also reducing the damage of vibration to the fixture itself. When the carrier 41 floats upward, the limiting part 412 will abut against the lower end of the cover plate 8. The maximum upward floating amount of the carrier 41 is limited; when the carrier 41 moves downward, it will abut against the upper end of the moving plate 3, limiting its maximum downward movement, thus ensuring that the floating of the carrier 41 is within a reasonable range. Simultaneously, during the floating process of the carrier 41, it can help maintain the posture of the carrier 41, reducing the possibility of it tilting. The cover plate 8 also prevents the intrusion of debris and oil, keeping the key parts of the carrier assembly 4 and the adjusting assembly 7 clean, reducing component wear and failure rate, and lowering maintenance costs. The elastic element 411 uses a spring.

[0021] In this embodiment, the moving plate 3 is provided with a limiting recess 30, which is used to accommodate the end of the elastic member 411 away from the load seat 41. The limiting recess 30 provides a accommodating space for the end of the elastic member 411 away from the load seat 41, which can limit the displacement of the elastic member 411 in the horizontal direction, prevent it from shifting, tilting or falling off during compression or rebound, ensure that its elastic support force on the load seat 41 is uniform and stable, so that the load seat 41 can more reliably fit the flange 11, further reduce local stress concentration caused by unstable support, and reduce the risk of deformation of the steering knuckle 1.

[0022] In this embodiment, the drilling assembly 5 further includes a mounting part 52 and a rotation drive device 53. The mounting part 52 is mounted on the adjustment mechanism 6, the rotation drive device 53 is mounted on the mounting part 52, and the drill bit 51 is mounted on the rotating end of the rotation drive device 53. The mounting part 52 stably mounts the rotation drive device 53 and the drill bit 51 on the adjustment mechanism 6, reducing vibration and displacement caused by loose components during drilling, making the rotation and feed of the drill bit 51 smoother, which helps to ensure the machining accuracy of the shaft hole 10 and reduce dimensional errors caused by vibration. The rotation drive device 53 is a motor.

[0023] In this embodiment, as Figure 5 As shown, the adjustment mechanism 6 includes: a mounting frame 61, an X-axis moving component 62, and a vertical moving component 63. The mounting frame 61 is mounted on the worktable 2. The X-axis moving component 62 includes: a first sliding plate 621 and a first linear drive device 622. The first sliding plate 621 is slidably mounted on the mounting frame 61 via a first slide rail 623. The first linear drive device 622 is mounted on the mounting frame 61, and its movable end is connected to the first sliding plate 621. The vertical moving component 63 includes: a mounting column 631 and a second linear drive device 632. The mounting column 631 is slidably mounted on the first sliding plate 621 via a second slide rail 633. The second linear drive device 632 is mounted on the first sliding plate 621 and is used to drive the mounting column 631 to move vertically. The mounting part 52 is mounted on the end of the mounting column 631 near the worktable 2. In the X-axis moving assembly 62, the first linear drive device 622 drives the first slide plate 621 to slide along the first slide rail 623 on the mounting bracket 61, thereby driving the vertical moving assembly 63 and the drilling assembly 5 to move synchronously along the X-axis, realizing the position adjustment of the drill bit 51 in the X-axis; in the vertical moving assembly 63, the second linear drive device 632 drives the mounting column 631 to slide vertically along the second slide rail 633 on the first slide plate 621, directly driving the mounting part 52 of the drilling assembly 5 and the drill bit 51 to move up and down, realizing the adjustment of the drill bit 51 in the vertical position (such as drilling depth, initial cutting position) to meet the processing requirements of different shaft hole 10 depths. Both the first linear drive device 622 and the second linear drive device 632 are cylinders.

These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of this utility model without creative effort, and these embodiments will all fall within the scope of protection of this utility model.
