Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery testing technology, specifically a chassis testing device. Background Technology

[0002] As a commonly used small-scale tillage machine in agricultural production, the stability and safety of the chassis structure of mini tillers directly affect tillage efficiency and operational safety. Chassis inspection is a crucial step in ensuring equipment performance during the manufacturing, repair, and maintenance of mini tillers.

[0003] The chassis inspection of mini tillers is mostly done manually. Therefore, it is necessary to raise the chassis of the mini tiller or for the maintenance personnel to crawl under the chassis to inspect it. This is very inconvenient in actual operation. At the same time, regardless of which method is used, the inspection personnel need to look up for a long time to observe, which leads to great fatigue for the maintenance personnel. In addition, being under the mini tiller for a long time poses a significant safety hazard.

[0004] In view of this, we propose a chassis detection device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a chassis detection device.

[0006] The technical solution of this utility model is: A chassis detection device includes a base. Two height driving mechanisms are symmetrically slidably mounted on the top of the base. Each height driving mechanism has a tire limiting component rotatably mounted on it. The tire limiting component includes an upper and a lower symmetrically arranged tire plate, with the ends of the two tire plates fixed together by a long screw. A turntable is fixedly connected to the side of the lower tire plate near the height driving mechanism. A rotating shaft is coaxially fixed on the turntable. A driving block connected to the height driving mechanism is rotatably connected to the rotating shaft. An adjustment component for driving the two height driving mechanisms to move towards or away from each other is installed on the base.

[0007] During use, the tire limiting assembly uses upper and lower tire plates fixed by long screws to firmly hold the tire in place, preventing it from slipping during testing and ensuring accuracy. The adjustment assembly can drive two height drive mechanisms to move in opposite directions, facilitating the testing of mini-tiller chassis with different wheelbases. This greatly improves the versatility and practicality of the testing device. The height drive mechanism can lift the mini-tiller, giving it ample space to turn over.

[0008] As a preferred technical solution, an extension plate is integrally formed at both ends of the top of the lower tile and both ends of the bottom of the upper tile, and two adjacent extension plates are connected by a long screw. This structural design, using extension plates in conjunction with long screws, enhances the stability of the connection between the upper and lower tiles, ensuring that the tire can be stably clamped between the two tiles.

[0009] As a preferred technical solution, a first movable slot is provided on the top of the base, and the adjustment component is installed in the first movable slot. The first movable slot on the top of the base is used to install the adjustment component, and the first movable slot provides installation space for the adjustment component.

[0010] As a preferred technical solution, the height driving mechanism includes a vertical support frame as the main body. The vertical support frame has an opening on the side near the tire limiting component, and a second movable groove is formed inside it. The driving block is slidably installed inside the second movable groove. This structural design makes the movement guidance of the driving block in the second movable groove better, and can accurately drive the tire limiting component to move in the vertical direction, thereby more precisely adjusting the height of the tire limiting component.

[0011] As a preferred technical solution, a single-threaded screw is rotatably installed inside the second movable slot. The drive block has a second threaded hole that is threadedly connected to the single-threaded screw. A first adjusting motor with an output shaft coaxially fixed to the top of the single-threaded screw is installed on the top of the vertical support frame. The single-threaded screw is driven to rotate by the first adjusting motor, thereby realizing the up-and-down movement of the drive block within the second movable slot.

[0012] As a preferred technical solution, each of the vertical support frames has an integrally formed lower extension block at its bottom that slides in connection with the first movable slot. The lower extension block not only enhances the stability of the connection between the vertical support frame and the base, but also makes the movement of the vertical support frame within the first movable slot more stable and smooth under the drive of the adjustment component.

[0013] As a preferred technical solution, the adjustment assembly includes a double-threaded screw rotatably mounted inside the first movable slot. Both ends of the double-threaded screw are threadedly connected to two lower extension blocks, respectively. Each lower extension block has a first threaded hole for threaded connection with the double-threaded screw. A second adjustment motor, with its output shaft coaxially fixed to one end of the double-threaded screw, is mounted on the outer wall of one side of the base. By rotatably connecting the double-threaded screw, which is mounted inside the first movable slot, to the two lower extension blocks (i.e., two height drive mechanisms), the forward and reverse rotation of the double-threaded screw can be used to move the two lower extension blocks (i.e., two height drive mechanisms) towards or away from each other.

[0014] As a preferred technical solution, an inclined platform is integrally formed at both ends of the base. The end of the inclined platform away from the base is an inclined surface, and the lower side of the inclined surface is flush with the bottom of the base. The inclined platform facilitates the movement of the tiller into and out of the detection device, and acts as a transition when the tiller is driven into or out of the detection device.

[0015] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the tire limiting component uses upper and lower tire plates fixed by a long screw to firmly hold the tire in place, preventing it from slipping during testing and ensuring accuracy. The adjustment component can drive two height drive mechanisms to move in opposite directions, facilitating the testing of mini-tiller chassis with different wheelbases. This greatly improves the versatility and practicality of the testing device. The height drive mechanism can lift the mini-tiller, providing it with ample space to turn over.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 This utility model provides a technical solution: A chassis detection device includes a base 1. Two height driving mechanisms 2 are symmetrically slidably mounted on the top of the base 1. Each height driving mechanism 2 has a tire limiting component 3 rotatably mounted on it. The two tire limiting components 3 are symmetrically arranged. Each tire limiting component 3 includes an upper tile 31 and a lower tile 30 symmetrically arranged. The ends of the two tiles are fixed together by a long screw 37. A turntable 33 is fixedly connected to the side of the lower tile 30 near the height driving mechanism 2. A rotating shaft 34 is coaxially fixed on the turntable 33. A driving block 35 connected to the height driving mechanism 2 is rotatably connected to the rotating shaft 34. An adjustment component for driving the two height driving mechanisms 2 to move towards or away from each other is installed on the base 1.

[0019] In use, the tire limiting component 3 uses an upper plate 31 and a lower plate 30 fixed by a long screw 37 to firmly hold the tire in place, preventing it from slipping during testing and ensuring accuracy. The adjustment component can drive two height drive mechanisms 2 to move in opposite directions, facilitating the testing of mini-tiller chassis with different wheelbases. This greatly improves the versatility and practicality of the testing device. The height drive mechanism 2 can lift the mini-tiller, giving it ample space to turn over.

[0020] In a preferred embodiment, both ends of the top of the lower tile 30 and both ends of the bottom of the upper tile 31 are integrally formed with an extension plate 32, and two adjacent extension plates 32 are connected by a long screw 37. This structural design, with the extension plates 32 connected by the long screw 37, enhances the stability of the connection between the upper tile 31 and the lower tile 30, ensuring that the tire can be stably clamped between the two tiles.

[0021] In a preferred embodiment, the top of the base 1 is provided with a first movable slot 11, and the adjustment component is installed in the first movable slot 11. The first movable slot 11 on the top of the base 1 is used to install the adjustment component, and the first movable slot 11 provides installation space for the adjustment component.

[0022] In a preferred embodiment, the height driving mechanism 2 includes a vertical support frame 20 as its main body. The vertical support frame 20 has an opening on the side near the tire limiting component 3, and a second movable groove 23 is formed inside it. The driving block 35 is slidably installed inside the second movable groove 23. This structural design makes the movement guidance of the driving block 35 in the second movable groove 23 better, and can accurately drive the tire limiting component 3 to move in the vertical direction, thereby more accurately adjusting the height of the tire limiting component 3.

[0023] In a preferred embodiment, a single-threaded screw 21 is rotatably mounted inside the second movable slot 23. The drive block 35 has a second threaded hole 36 that is threadedly connected to the single-threaded screw 21. A first adjusting motor 22, with its output shaft coaxially fixed to the top of the single-threaded screw 21, is mounted on the top of the vertical support frame 20. The first adjusting motor 22 drives the single-threaded screw 21 to rotate, thereby enabling the drive block 35 to move up and down within the second movable slot 23.

[0024] As a preferred embodiment, each vertical support frame 20 has an integrally formed lower extension block 24 at its bottom, which is slidably connected to the first movable groove 11. The lower extension block 24 not only enhances the stability of the connection between the vertical support frame 20 and the base 1, but also makes the movement of the vertical support frame 20 within the first movable groove 11 more stable and smooth under the drive of the adjustment component.

[0025] In a preferred embodiment, the adjustment assembly includes a double-threaded screw 12 rotatably mounted inside the first movable groove 11. Both ends of the double-threaded screw 12 are threadedly connected to two lower extension blocks 24. Each lower extension block 24 has a first threaded hole 25 threadedly connected to the double-threaded screw 12. A second adjustment motor 13, with its output shaft coaxially fixed to one end of the double-threaded screw 12, is mounted on one outer wall of the base 1. By rotatably connecting the double-threaded screw 12, mounted inside the first movable groove 11, to the two lower extension blocks 24, the forward and reverse rotation of the double-threaded screw 12 allows the two lower extension blocks 24 (i.e., the two height drive mechanisms 2) to move towards or away from each other.

[0026] In a preferred embodiment, a tilting platform 10 is integrally formed at both ends of the base 1. The end of the tilting platform 10 away from the base 1 is an inclined surface, and the lower side of the inclined surface is flush with the bottom of the base 1. The tilting platform 10 facilitates the movement of the tiller into and out of the detection device, and the tilting platform 10 serves as a transition when the tiller is driven into or out of the detection device.

[0027] When using the chassis detection device of this utility model, firstly, the mini-tiller is driven onto the top of the base 1, and then the distance between the two height drive mechanisms 2 is adjusted by the adjustment component. Driven by the second adjustment motor 13, the double-threaded lead screw 12 of the adjustment component rotates within the first movable slot 11. The two lower extension blocks 24, threadedly connected to the double-threaded lead screw 12, move the vertical support frame 20 towards or away from each other under the forward and reverse rotation of the lead screw until the tire limiting component 3 is fully matched with the wheel track of the mini-tiller. Then, the mini-tiller's tire is placed between the upper tile 31 and the lower tile 30, and the upper tile 31 and the lower tile 30 are fixed together by the long screw 37. Next, the first adjustment motor 22 of the height drive mechanism 2 is activated. The output shaft of the adjusting motor 22 drives the single threaded screw 21 in the second movable groove 23 to rotate. The drive block 35, which is threadedly connected to the single threaded screw 21, rises vertically along the second movable groove 23. Through the rotating shaft 34 and the turntable 33, the tire limiting assembly 3 and the clamped tire rise synchronously, raising the entire micro-tiller to the required height. Then, the micro-tiller is manually rotated 180 degrees around its tires, so that the micro-tiller's handlebars contact the top of the base 1, thus flipping the micro-tiller's chassis to the top for easy inspection of the micro-tiller's chassis.
