Description

Technical Field

[0001] This invention relates to the field of steering tie rod processing and assembly technology, and specifically to an automatic steering tie rod feeding device and method. Background Technology

[0002] With the continuous development of the commercial vehicle industry, the demand for steering tie rods is constantly increasing. However, due to the characteristics of steering tie rods, such as their long length and heavy weight, manual loading has drawbacks, including high labor intensity, low work efficiency, high labor costs, and significant fluctuations in loading cycle time due to the influence of human physical strength. Furthermore, during the machining of steering tie rods, the evaporation of coolant produces water mist and an unpleasant odor, easily creating a humid machining environment, and long-term work in this environment poses certain safety hazards to workers. Therefore, some factories have begun to use lifting devices for loading steering tie rods.

[0003] Currently, existing lifting devices typically have sprockets installed at the upper and lower ends of the frame, with a conveyor chain connected between the two sprockets. One or more support platforms are connected to the conveyor chain, thereby lifting the material on the loading rack by rotating the conveyor chain.

[0004] However, in practical applications, since multiple steering tie rods are usually placed on the loading rack, when the conveyor chain drives the support platform and the corresponding steering tie rod to move upward, the remaining steering tie rods will exert horizontal pressure on the conveyor chain, thereby increasing the resistance of the conveyor chain and increasing the output power and energy consumption of the engine connected to the conveyor chain. Summary of the Invention

[0005] The technical problem solved by the present invention is to provide an automatic feeding device and method for steering tie rods that can reduce the upward resistance of the conveyor chain during the feeding process, so as to reduce the output power of the engine connected to the conveyor chain and reduce energy consumption.

[0006] To address the aforementioned technical problems, this invention provides an automatic steering tie rod feeding device, comprising a gear chain lifting assembly and a feeding frame. The feeding frame includes a supporting base plate and a tie rod holder. The supporting base plate is located on the feeding side of the gear chain lifting assembly. A second base and a first base are sequentially fixedly mounted on the upper end of the supporting base plate in a direction away from the gear chain lifting assembly. Rollers are rotatably mounted on the upper ends of both the second and first bases, with the height of the rollers on the second base being less than the height of the rollers on the first base. The tie rod holder is placed on the upper ends of the second and first bases. A tie rod blocking part is provided on the side of the tie rod holder closest to the gear chain lifting assembly, and a sliding blocking part is provided on the side of the tie rod holder away from the gear chain lifting assembly. At this time, if the present invention is used to load the steering tie rod, since the tie rod rack in the present invention can be slidably installed on the base one and base two provided on the upper end of the support base plate, and the height of the roller provided on base two is less than the height of the roller provided on base one, the present invention can, on the one hand, ensure that the tie rod rack and the steering tie rod placed inside it can gradually approach the gear chain lifting assembly under the action of gravity, so as to realize the contact between the gear chain lifting assembly and the steering tie rod and facilitate the lifting of the steering tie rod; on the other hand, when the gear chain lifting assembly lifts the corresponding steering tie rod, through the interaction force between the gear chain lifting assembly and numerous steering tie rods, it can push the tie rod rack and the steering tie rod placed inside the tie rod rack in the opposite direction to move away from the gear chain lifting assembly, so as to reduce the horizontal compression of the gear chain lifting assembly by other steering tie rods, thereby facilitating the lifting of the steering tie rod by the gear chain lifting assembly, reducing the stress loss of the gear chain lifting assembly, and greatly saving resources and reducing energy consumption.

[0007] Furthermore, the gear chain lifting assembly includes a mounting frame, with an upper gear mechanism and a lower gear mechanism respectively provided at the upper and lower ends of the mounting frame. The upper gear mechanism is connected to a drive mechanism, and two gear chains are connected between the lower gear mechanism and the upper gear mechanism. Each gear chain is equipped with at least one lifting hook through fasteners and a connecting plate, and the lifting hook can move upward with the rotation of the gear chain, thereby realizing the automatic feeding action of the corresponding steering tie rod.

[0008] Furthermore, the upper gear mechanism includes a connecting shaft, which is connected to the drive mechanism. Bearing seats are rotatably mounted on both ends of the connecting shaft via bearings, and these bearing seats are fixedly mounted on the upper end of the mounting frame. Gears are also fixedly mounted on both ends of the connecting shaft via keys, and these gears mesh with corresponding gear chains. Thus, when the drive mechanism drives the connecting shaft to rotate, the connecting shaft can drive the gears to rotate in the corresponding direction, thereby driving the gear chain to rotate and causing the lifting hooks on the gear chain to move in the corresponding direction.

[0009] Furthermore, a top sleeve is provided between the bearing housing and the first gear, and a plug is provided on the side of the bearing housing away from the first gear. The top sleeve prevents the first gear from moving axially, and the plug prevents dust from entering the corresponding bearing housing.

[0010] Furthermore, the drive mechanism includes a drive motor, which is mounted on the mounting frame via a motor mount. The output end of the drive motor is connected to the connecting shaft via a transmission mechanism. Moreover, the transmission mechanism can be a gear transmission mechanism or a chain transmission mechanism, etc.

[0011] Furthermore, the upper gear mechanism is covered with a protective cover, which isolates the upper gear mechanism and the upper part of the gear chain from the external environment to prevent accidents such as hand pinching. In addition, since there is a certain angle between the protective cover and the lifting hook, when the steering lever is lifted, the steering lever is located between the lifting hook and the protective cover and will not easily fall off.

[0012] Furthermore, the lower gear mechanism includes a second connecting shaft, with sliders rotatably mounted at both ends of the second connecting shaft via bearings, and the sliders being connected to the mounting frame via fastening bolts; the two ends of the second connecting shaft are also fixedly mounted with a second gear via keys, and the second gear meshes with a corresponding gear chain.

[0013] Furthermore, the lower gear mechanism also includes a support plate and a mounting plate. The support plate is fixedly mounted on the mounting frame, and a top pin is installed at the upper end of the support plate through a threaded through hole. The lower end of the top pin passes through the threaded through hole and abuts against the upper end of the slider. The mounting plate is located between the mounting frame and the slider. The mounting frame is provided with a threaded connection hole, the mounting plate is provided with an elongated hole one, and the slider is provided with an elongated hole two. The length direction of both elongated holes one and two is vertical. The fastening bolt passes through elongated hole two, elongated hole one, and the threaded connection hole and is connected to a fastening nut. In this case, since the slider in this invention can slide vertically relative to the mounting frame, the position of the slider can be adjusted by turning the top pin, thereby adjusting the tension of the gear chain.

[0014] Furthermore, a top sleeve is provided between the slider and the second gear, and a plug is provided on the side of the slider away from the second gear. The top sleeve prevents the second gear from moving axially, and the plug prevents dust from entering the corresponding slider.

[0015] In addition, the present invention also provides a feeding method using the above-mentioned automatic feeding device for steering tie rods, which includes the following steps:

[0016] Step 1: Use a forklift to place the rack containing the steering tie rods above the rollers on base 1 and base 2.

[0017] Step 2: The tie rod rack tilts and slides down under its own weight and the weight of the steering tie rod it stores, until the sliding stop of the tie rod rack comes into contact with the base.

[0018] Step 3: Start the drive mechanism. The drive mechanism drives the gear chain to rotate, and the gear chain drives the lifting hook to move until the lifting hook moves to below the steering tie rod.

[0019] Step four: The lifting hook drives the corresponding steering tie rod to rise, and pushes the tie rod material rack to move away from the gear chain;

[0020] Step 5: The lifting hook moves the corresponding steering tie rod to the upper end of the gear chain. At the same time, the tie rod rack tilts and slides down under its own weight and the weight of the steering tie rod it stores, until the sliding stop of the tie rod rack abuts against the base again.

[0021] Step six: Repeat steps three, four and five until all steering tie rods on the tie rod rack have been loaded, then turn off the drive mechanism.

[0022] As can be seen from the above technical solutions, the present invention has the following advantages: When using the present invention to process steering tie rods, on the one hand, the present invention can ensure, under the action of gravity, that the tie rod holder and the steering tie rods placed inside it can gradually approach the gear chain lifting assembly, so as to achieve contact between the gear chain lifting assembly and the steering tie rods and facilitate the lifting of the steering tie rods; on the other hand, when the gear chain lifting assembly lifts the corresponding steering tie rods, the force between the gear chain lifting assembly and numerous steering tie rods can push the tie rod holder and the steering tie rods placed inside it in the opposite direction to move away from the gear chain lifting assembly, so as to reduce the horizontal compression of the gear chain lifting assembly by other steering tie rods, thereby facilitating the lifting of the steering tie rods by the gear chain lifting assembly, reducing the stress loss of the gear chain lifting assembly, and greatly saving resources and reducing energy consumption.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1

[0033] like Figure 1 , Figure 2 As shown in the figure, this embodiment 1 provides an automatic feeding device for steering tie rods, which includes a gear chain lifting assembly 1 and a feeding rack placed in sequence. The gear chain lifting assembly 1 is used to lift the steering tie rods, and the feeding rack is used to temporarily store the steering tie rods.

[0034] Specifically, such as Figure 2 , Figure 3As shown, the gear chain lifting assembly 1 includes a mounting frame 17. An upper gear mechanism 13 and a lower gear mechanism 18 are respectively provided at the upper and lower ends of the mounting frame 17. The upper gear mechanism 13 is connected to a drive mechanism 8, which includes a drive motor 11. The drive motor 11 is mounted on the mounting frame 17 via a motor mount 12, and its output end is connected to the upper gear mechanism 13 via a transmission mechanism 10. Two gear chains 14 are connected between the lower gear mechanism 18 and the upper gear mechanism 13. Each gear chain 14 is equipped with at least one lifting hook 16 via fasteners and a connecting plate 15. The lifting hook 16 can move upwards with the rotation of the gear chain 14 and automatically feed the corresponding steering lever.

[0035] like Figure 4 As shown, the upper gear mechanism 13 includes a connecting shaft 19, with gears 20 fixedly mounted at both ends of the connecting shaft 19 via keys. The gears 20 mesh with the corresponding gear chain 14. Bearing seats 22 are also rotatably mounted at both ends of the connecting shaft 19 via bearings. The bearing seats 22 are fixedly mounted on the upper end of the mounting frame 17, and a top sleeve 21 is provided between the bearing seat 22 and the gears 20 to prevent the gears 20 from moving axially. A cover 24 is provided on the side of the bearing seat 22 away from the gears 20 to prevent dust from entering the bearing seat 22. After one end of the connecting shaft 19 passes through the bearing seat 22, it is connected to the output end of the drive motor 11 via a transmission mechanism 10. The transmission mechanism 10 can be either a gear transmission mechanism or a chain transmission mechanism. When the drive motor 11 drives the connecting shaft 19 to rotate, the connecting shaft 19 can drive the gear 20 to rotate in the corresponding direction, thereby driving the gear chain 14 to rotate, and driving the lifting hook 16 on the gear chain 14 to move in the corresponding direction.

[0036] In addition, as a preferred option, such as Figure 1 , Figure 2 As shown, in this embodiment 1, a protective cover 9 is also provided on the outer side of the upper gear mechanism 13, and a certain angle is maintained between the protective cover 9 and the lifting hook 16. In this way, this embodiment 1 isolates the upper part of the upper gear mechanism 13 and the gear chain 14 from the external environment through the protective cover 9, preventing accidents such as hand pinching. At the same time, when the steering tie rod is lifted, it will not fall easily because it is located between the lifting hook 16 and the protective cover 9.

[0037] like Figure 5As shown, the lower gear mechanism 18 includes a second connecting shaft 28, and two ends of the second connecting shaft 28 are fixedly mounted with gears 29 by keys. The gears 29 mesh with the corresponding gear chain 14. The two ends of the second connecting shaft 28 are also rotatably mounted with sliders 26 by bearings. The sliders 26 are mounted on the mounting frame 17 by fastening bolts. A top sleeve 21 is also provided between the sliders 26 and the gears 29 to prevent the gears 29 from moving axially. A cover 24 is also provided on the side of the sliders 26 away from the gears 29 to prevent dust from entering the corresponding sliders 26.

[0038] In addition, preferably, the lower gear mechanism 18 also includes a support plate 25 and a mounting plate 27. The support plate 25 is fixedly mounted on the mounting frame 17, and a top pin 23 is installed on the upper end of the support plate 25 through a threaded through hole. The lower end of the top pin 23 passes through the threaded through hole and abuts against the upper end of the slider 26. The mounting plate 27 is located between the mounting frame 17 and the slider 26. A threaded connection hole is provided on the mounting frame 17 at a position opposite to the slider 26. An elongated hole one is provided on the mounting plate 27 at a position opposite to the slider 26, and an elongated hole two is provided on the slider 26. The length directions of both elongated holes one and two are vertical. A fastening bolt passes through elongated hole two, elongated hole one, and the threaded connection hole in sequence and connects to a fastening nut, thereby vertically and slidably connecting the slider 26, the mounting plate 27, and the mounting frame 17 together. Since the slider 26 in this embodiment 1 can slide vertically relative to the mounting frame 17, the position of the slider 26 can be adjusted by turning the top pin 23, thereby achieving the purpose of adjusting the tightness of the gear chain 14.

[0039] like Figure 1 , Figure 2 , Figure 6As shown, the feeding rack includes a support base plate 6 and a pull rod rack 3. The support base plate 6 is located on the feeding side of the gear chain lifting assembly 1, and a second base 4 and a first base 5 are sequentially fixedly installed on the upper end of the support base plate 6 in a direction away from the gear chain lifting assembly 1. Rollers 31 are rotatably installed on the upper ends of both the second base 4 and the first base 5 through pins 30 and bearings, and the height of the rollers 31 on the second base 4 is less than the height of the rollers 31 on the first base 5. The pull rod holder 3 is placed on the upper end of the second base 4 and the first base 5. The pull rod holder 3 is inclinedly provided with a pull rod blocking part 2 on the side near the gear chain lifting assembly 1, and a sliding blocking part 7 is provided on the side away from the gear chain lifting assembly 1. In this way, when the pull rod holder 3 is placed on the first base 5 and the second base 4 and slides down a certain distance, it can block the pull rod holder 3 through the abutment between the sliding blocking part 7 and the first base 5. The pull rod blocking part 2 blocks the steering pull rod stored on the pull rod holder 3 to prevent it from falling.

[0040] Furthermore, when using this embodiment 1 to load steering tie rods, since the tie rod holder 3 in this embodiment 1 can be slidably mounted on the base 5 and base 4 provided on the upper end of the support base plate 6, and the height of the roller 31 provided on the base 4 is less than the height of the roller 31 provided on the base 5, this embodiment 1 can, on the one hand, ensure that the tie rod holder 3 and the steering tie rods placed inside it can gradually approach the gear chain lifting assembly 1 under the action of gravity, so as to achieve contact between the gear chain lifting assembly 1 and the steering tie rods and facilitate the lifting of the steering tie rods; on the other hand, when the gear chain lifting assembly 1 lifts the corresponding steering tie rods, the force between the gear chain lifting assembly 1 and the numerous steering tie rods can push the tie rod holder 3 and the steering tie rods placed inside the tie rod holder 3 in the opposite direction to move away from the gear chain lifting assembly 1, so as to reduce the horizontal compression of the gear chain lifting assembly 1 by other steering tie rods, thereby facilitating the lifting of the steering tie rods by the gear chain lifting assembly 1, reducing the stress loss of the gear chain lifting assembly 1, and greatly saving resources and reducing energy consumption.

[0044] Step 2: The tie rod rack tilts and slides down under its own weight and the weight of the steering tie rod it stores, until the sliding stop of the tie rod rack comes into contact with the base.

[0045] Step 3: Start the drive mechanism. The drive mechanism drives the gear chain to rotate, and the gear chain drives the lifting hook to move until the lifting hook moves to below the steering tie rod.

[0046] Step four: The lifting hook drives the corresponding steering tie rod to rise, and pushes the tie rod material rack to move away from the gear chain;

[0047] Step 5: The lifting hook moves the corresponding steering tie rod to the upper end of the gear chain. At the same time, the tie rod rack tilts and slides down under its own weight and the weight of the steering tie rod it stores, until the sliding stop of the tie rod rack abuts against the base again.
