Description

Technical Field

[0001] This invention relates to the field of steering knuckle processing technology, and in particular to an automotive steering knuckle forming apparatus. Background Technology

[0002] The steering knuckle is the hinge that controls wheel steering. After the steering knuckle is forged, a hole needs to be drilled at one end to connect the pin, thus completing the final forming of the steering knuckle.

[0003] Chinese invention patent CN115090922A discloses a hole-opening device, particularly a hole-opening device for steering knuckle forgings. This device provides a steering knuckle forging hole-opening device that avoids deformation of the forging and is more convenient for users. The device includes a base, support blocks, a square plate, guide rails, sliding frames, and an electric drill bit. Support blocks are symmetrically connected to the rear of the base, and a square plate is connected between the tops of the two support blocks. Guide rails are symmetrically connected to the rear of the base, located behind the support blocks. Sliding frames are slidably connected within each guide rail, and an electric drill bit is connected between the two sliding frames. The steering knuckle is placed on the placement plate, which moves the steering knuckle to below the electric drill bit. The output shaft of the drive motor rotates, causing the sliding frames to move the electric drill bit downwards to drill a hole in the steering knuckle, thus preventing deformation of the steering knuckle.

[0004] The aforementioned device transports the steering knuckle to a designated position via a placement mechanism, and then performs drilling operations using a drill bit. However, the placement mechanism lacks a structure for securing the steering knuckle during use, resulting in insufficient stability of the steering knuckle during drilling. Furthermore, since there are multiple drilling positions on the steering knuckle, the placement mechanism in the aforementioned structure cannot make corresponding adjustments according to the different drilling positions of the steering knuckle. Therefore, the aforementioned device still has certain shortcomings.

[0005] Therefore, it is necessary to provide an automotive steering knuckle forming device to solve the above-mentioned technical problems. Summary of the Invention

The end face of the movable ring near the rod extends outward to form a boss, and a clamping bolt is threaded onto the boss. A pull rope is fixedly connected to one end face of the stop block near the rotating block. The other end of the pull rope extends into the rotating block and downward along the axis of the rod sleeve. A first spring is provided at the bottom inside the fixed cylinder. The first spring is disposed between the rod and the fixed cylinder. An adjusting screw is threadedly connected to the bottom inside the rod sleeve. One end of the pull rope placed inside the rod sleeve is connected to the adjusting screw.

[0010] As a further aspect of the present invention: the driving assembly includes a sleeve disposed on one side of the rod sleeve, a driving gear being sleeved on the outer side of the sleeve via a one-way bearing, a driven gear meshing with the driving gear being fixedly sleeved on the outer side of the rod sleeve, a driving shaft being disposed inside the sleeve, a collar being slidably sleeved on the outer side of the driving shaft, a slider being slidably disposed at the bottom end of the collar, a locking block being elastically connected to the outer side of the slider, a plurality of locking strips cooperating with the locking block being evenly arranged on the inner wall of the sleeve, a threaded sleeve being fixedly connected to the bottom of the platform, the top end of the collar extending into the threaded sleeve and being threadedly connected thereto, a driving gear being fixedly sleeved on the outer bottom end of the driving shaft, an incomplete gear meshing on the outer side of the driving gear, and a connecting ring being disposed at the outer bottom end of the driving shaft, and a coil spring being disposed between the driving shaft and the connecting ring.

[0011] As a further aspect of the present invention: a limiting groove is formed on the outer circumferential surface of the drive shaft, and a limiting block that cooperates with the limiting groove is fixedly connected to the inner wall of the collar.

[0012] As a further aspect of the present invention: a bracket is fixedly connected to the bottom of the platform, the rod sleeve and the sleeve both pass through the bracket and are rotatably connected to it, and the connecting ring is fixedly connected to the inner bottom end of the bracket.

Since the meshing time of the driving gear and the driven gear are different, the position of the end at the slot is also different, thus the position of the drill hole in the front-back direction can be adjusted. This device, through the cooperation of the adjustment component and the drive component, can uniformly adjust the position of the opening on the end, which is beneficial to the final forming of the steering knuckle. Since the above device does not require individual fixing and adjustment of the drilling position for each steering knuckle during use, the operation steps are optimized, the drilling forming efficiency is improved, and the operation is convenient.

[0030] like Figure 1 As shown, an automotive steering knuckle forming device includes a platform 1 and a rotating block 7 rotatably disposed on the top of the platform 1. A plurality of fixed cylinders 2 connected to the steering knuckle 6 are fixedly arranged on the outer side of the rotating block 7. Specifically, the steering knuckle 6 is generally composed of a rod portion 5 and an end portion 4 connected to the rod portion 5. The aforementioned fixed cylinders 2 are connected to the rod portion 5 of the steering knuckle 6. In order to facilitate drilling and forming of the end portion 4 of the steering knuckle 6, the plurality of fixed cylinders 2 are arranged in a ring array on the outer side of the rotating block 7 to ensure that the distance between two adjacent fixed cylinders 2 is equal.

[0031] In actual use, a drill bit 3 is arranged above the platform 1. The drill bit 3 is connected to an external power system. For example, the drill bit 3 is driven to move downwards to open a hole at the end 4 of the steering knuckle 6 by a hydraulic rod. Of course, a slot is opened below the drill bit 3 on the platform 1, and a support rod is fixedly installed at the top of the slot to support the end 4 of the steering knuckle 6, so as to avoid interference between the drill bit 3 and the platform 1 when it descends.

[0032] like Figure 2-7As shown in Figures 9-10, in order to facilitate drilling operations on end 4, a rod sleeve 11 is provided at the bottom of the platform 1. The top end of the rod sleeve 11 passes through the platform 1 and is fixedly connected to the rotating block 7, thereby driving the rotating block 7 and the fixed cylinder 2 on its outer side to rotate. The rod sleeve 11 can be rotatably connected to the platform 1 through a bearing. An adjustment component is provided inside the rod sleeve 11 to adjust the position of the rod 5 inside the fixed cylinder 2, thereby enabling the drilling position to be adjusted along a direction parallel to the rod 5. A drive component is provided on the outer side of the rod sleeve 11, which can drive the rod sleeve 11 to rotate.

[0033] Specifically, the aforementioned adjustment assembly includes a stop block 25 slidably disposed inside the fixed cylinder 2, and a movable ring 9 sleeved on the outside of the fixed cylinder 2. The movable ring 9 and the stop block 25 are fixed together by a connecting block 24. A groove is provided on the cylinder wall of the fixed cylinder 2 to slide and engage with the connecting block 24. The end face of the movable ring 9 near the rod 5 extends outward to form a boss 23, and a clamping bolt 22 is threaded onto the boss 23. A pull rope 19 is fixedly connected to one end face of the stop block 25 near the rotating block 7. The other end of the pull rope 19 extends into the rotating block 7 and downward along the axis of the rod sleeve 11. The pull rope 19 is slidably connected to the rotating block 7. A first spring 20 is provided at the bottom of the interior of the fixed cylinder 2, and the first spring 20 is disposed between the rod 5 and the fixed cylinder 2.

[0034] Furthermore, an adjusting screw 12 is threadedly connected to the bottom of the inner side of the sleeve 11. A cylindrical connector is fixedly connected to one end of the pull rope 19 inside the sleeve 11. The connector is rotatably engaged with the adjusting screw 12. Since there are multiple pull ropes 19, they are combined into one strand inside the sleeve 11 and connected to the connector, which makes it easy to adjust multiple pull ropes 19 simultaneously by adjusting the adjusting screw 12.

[0035] The aforementioned drive assembly includes a sleeve 16 disposed on one side of the sleeve 11. A drive gear 29 is sleeved on the outer side of the sleeve 16 via a one-way bearing, while a driven gear 10 meshing with the drive gear 29 is fixedly sleeved on the outer side of the sleeve 11. A drive shaft 14 is disposed inside the sleeve 16. In order for the drive shaft 14 to drive the sleeve 16 to rotate, a collar 17 is slidably sleeved on the outer side of the drive shaft 14. Specifically, a limiting groove 35 is formed on the outer circumferential surface of the drive shaft 14, and a limiting block 30 that cooperates with the limiting groove 35 is fixedly connected to the inner wall of the collar 17. A slider 28 is slidably disposed at the bottom end of the collar 17, and a locking block 31 is elastically connected to the outer side of the slider 28. A plurality of locking strips 32 are evenly arranged on the inner wall of the sleeve 16, and a locking groove that cooperates with the locking block 31 is formed between two adjacent locking strips 32. When the locking block 31 is placed between two adjacent locking strips 32, the rotating collar 17 can drive the sleeve 16 to rotate.

[0036] Furthermore, a threaded sleeve 18 is fixedly connected to the bottom of the platform 1, and the top end of the collar 17 extends into the threaded sleeve 18 and is threadedly connected to it.

[0037] Furthermore, a drive gear 27 is fixedly sleeved on the outer bottom end of the drive shaft 14, and an incomplete gear 15 meshes with the outer side of the drive gear 27. A connecting ring 13 is arranged on the outer bottom end of the drive shaft 14, and a coil spring 21 is sleeved on the outer side of the drive shaft 14. The two free ends of the coil spring 21 are respectively connected to the outer wall of the drive shaft 14 and the inner wall of the connecting ring 13.

[0038] In practical use, the incomplete gear 15 is equipped with a rotating shaft, which is connected to an external motor drive. This structure can drive the incomplete gear 15 to rotate. When the incomplete gear 15 meshes with the drive gear 27, it can drive the drive shaft 14 to rotate. Then, through the cooperation of the limiting block 30 and the limiting groove 35, the drive shaft 14 can drive the collar 17 to rotate. The collar 17 can drive the locking block 31 at its bottom to rotate. With the cooperation of the locking block 31 and the locking strip 32, the collar 17 can drive the sleeve 16 to rotate. Then, through the meshing of the driving gear 29 and the driven gear 10, the rod sleeve 11 is driven to rotate. The rod sleeve 11 can drive the rotating block 7 and the sleeve 16 on its outer side to rotate, thereby driving the steering knuckle 6 to rotate.

[0039] Because the collar 17 is threadedly connected to the sleeve 18, during the rotation of the collar 17, the collar 17 can move upward relative to the sleeve 16, thereby causing the locking block 31 to move upward relative to the locking strip 32. When the locking block 31 and the locking strip 32 are misaligned, the locking block 31 cannot drive the sleeve 16 to rotate. At this time, the collar 17 and the locking block 31 at its bottom are in a free-spinning state. Then, when the incomplete gear 15 and the drive gear 27 are not meshed, under the force of the coil spring 21, the drive shaft 14 can be driven to rotate in the opposite direction and move downward relative to the sleeve 16. Because the locking block 31 is elastically connected to the slider 28, when the locking block 31 contacts the locking strip 32, the locking block 31... 1 can be stored inside the slider 28. Then, as the locking block 31 rotates, it can re-engage between the two adjacent locking strips 32. Since the sleeve 16 is engaged with the drive gear 27 through a one-way bearing, the sleeve 16 is in a state of rotation during the process of the locking block 31 moving downward and re-engaging with the two adjacent locking strips 32. It cannot drive the drive gear 29 to rotate. During the above process, the end 4 of one of the steering knuckles 6 just rotates to the slot. Then, the end 4 can be drilled and shaped by the drill bit 3. This process is repeated. When the incomplete gear 15 meshes with the drive gear 27 again, it can drive the end 4 of the next steering knuckle 6 to move to the slot.

[0040] When the position of the drill hole needs to be adjusted, the adjusting screw 12 can be rotated to move it in the vertical direction. When the adjusting screw 12 moves downward, the stop block 25 and the rod 5 connected to it can be moved towards the rotating block 7 by the pull rope 19, so that the position of the drill hole can be adjusted along the direction of the rod 5. The specific adjustment process is as follows: loosen the clamping bolt 22, rotate the adjusting screw 12 to pull the pull rope 19 to move, and then adjust the position of the rod 5. Then fix the rod 5 inside the fixed cylinder 2 by the clamping bolt 22, or directly install multiple balls on the inner wall of the fixed cylinder 2 and fix the rod 5 by the clamping bolt 22. In the subsequent adjustment process, it is only necessary to use the pull rope 19 to drive the rod 5 to move inside the fixed cylinder 2 against the pressure of the first spring 20.

[0041] Since the slider 28 is slidably connected to the collar 17, in actual use, the engagement time between the locking block 31 and the locking strip 32 can be controlled by adjusting the distance the slider 28 extends outward, thereby controlling the meshing time between the driving gear 29 and the driven gear 10. Since the meshing time of the driving gear 29 and the driven gear 10 is different, the position of the end 4 at the slot is also different, thus the position of the drill hole can be adjusted in the front and back directions.

[0042] In summary, this device, through the coordination of the adjustment component and the drive component, can uniformly adjust the position of the opening on the end 4, which is beneficial to the final forming of the steering knuckle 6. Since the above device does not require individual fixing and drilling position adjustment for each steering knuckle 6 during use, it optimizes the operation steps, improves the drilling and forming efficiency, and is easy to operate.

[0043] like Figure 7-8 As shown, a groove is provided on the outer surface of the slider 28, and a guide rod 33 is fixedly connected to the inner end face of the groove. The aforementioned locking block 31 is slidably disposed inside this groove. The guide rod 33 extends into the inside of the locking block 31 and is slidably connected to it. Specifically, a blind hole is provided on the end face of the locking block 31, and one end of the guide rod 33 extends into the blind hole. A second spring 34 is also provided inside the blind hole, so that the two ends of the second spring 34 are fixedly connected to the guide rod 33 and the end face of the blind hole, respectively, thereby realizing the elastic connection between the slider 28 and the locking block 31.

[0044] like Figure 5As shown, a strip groove is provided at the bottom end of the collar 17, and the slider 28 is slidably disposed inside this strip groove. A locking bolt 26 is threadedly connected to the outer side of the collar 17. By rotating the locking bolt 26, the slider 28 can be fixed. This device is conducive to adjusting the position of the slider 28, thereby controlling the engagement time between the locking block 31 and the locking strip 32. Of course, a scale can be provided on the outer side of the slider 28 for easy adjustment by the operator.

[0045] like Figure 2 As shown, a bracket 36 is fixedly connected to the bottom of the platform 1. The rod sleeve 11 and the sleeve 16 both pass through the bracket 36 and are rotatably connected to it. The connecting ring 13 is fixedly connected to the bottom of the inside of the bracket 36. The motor is also fixedly connected to the bracket 36.

[0046] like Figure 1 As shown, a base 8 is fixedly connected to the top of the platform 1, so that the rotating block 7 is rotatably disposed inside the base 8, and a rubber pad is provided on the inner wall of the base 8, so that there is a large friction between the rotating block 7 and the base 8, which helps to maintain the stability of the rotating block 7 when it rotates.

[0047] like Figure 7-8 As shown, chamfers are provided at both the top and bottom of the card block 31, so that when the card block 31 moves downward and comes into contact with the card strip 32, the card strip 32 can squeeze the card block 31 into the slider 28, thus avoiding interference between the card block 31 and the card strip 32.
