Description

Technical Field

[0001] This utility model relates to the field of vehicle axle transfer technology, and more specifically, to a vehicle axle transfer clamping mechanical claw. Background Technology

[0002] The axle connects to the vehicle frame and mounts the wheels via the suspension, primarily responsible for load transfer and maintaining driving function. Structurally, it can be divided into two categories: integral axle using a combination of integral and non-independent suspension, and disconnect axle using a combination of independent and discrete suspension. Based on the drive method, it is classified into four types: steering axle, drive axle, steering-drive axle, and support axle: in front-engine, rear-wheel-drive vehicles, the front axle is a steering axle and the rear axle is a drive axle; in front-engine, front-wheel-drive vehicles, the front axle is a steering-drive axle and the rear axle is a support axle.

[0003] The axle is dumbbell-shaped and quite large, requiring specialized robotic grippers for handling and transport. Due to its size and weight at both ends, the robotic grippers may fail to grasp the axle's center of gravity, leading to instability and slippage under gravity, further destabilizing the axle. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a mechanical claw for transferring and holding a vehicle axle. It uses a first telescopic rod to extend and fix the distance between the two ends of the vehicle axle and the mechanical claw body, making it less likely for the vehicle axle to slip. At the same time, a counterweight is used to adjust the overall center of gravity of the mechanical claw body and the vehicle axle.

[0005] This utility model is achieved through the following technical solution: a mechanical claw for transferring and holding a vehicle axle, including a housing, with mechanical claw bodies provided on both sides of the bottom length direction of the housing, each mechanical claw body including two claw petals, and a first driving member for driving the claw petals to close on the housing; A stop is rotatably connected to one side of the housing in the width direction. A second driving member is provided on the housing to drive the stop to rotate. The stop includes a first frame. Both sides of the first frame away from the housing are provided with first telescopic rods. A counterweight is fixedly connected to the side of the housing away from the stop. The counterweight includes a second frame. Both sides of the second frame away from the housing are provided with second telescopic rods. A counterweight block is fixedly connected to the output shaft of the second telescopic rod.

[0006] Furthermore, an arc groove is provided at the end of the claw flap that is away from the shell.

[0007] Furthermore, the inner side of the claw flap is covered with a rubber anti-slip layer.

[0008] Furthermore, a rubber pad is provided at the end of the first telescopic rod away from the first frame.

[0009] Furthermore, a pressure trigger switch is provided on the side of the rubber pad away from the first frame, and the pressure trigger switch is electrically connected to the second telescopic rod.

[0010] Furthermore, an arc-shaped buckle is rotatably connected to one side of the claw flap, and a third driving component is provided on the claw flap to drive the arc-shaped buckle to rotate. The arc-shaped buckle is used to support the bottom of the axle after rotation.

[0011] Furthermore, a projection lamp is fixedly connected to the middle section of the bottom of the housing.

[0012] The technical solution of this utility model has at least the following beneficial effects: When gripping the axle, the mechanical claws of the housing grip the axle, allowing the clamping force to be applied more evenly to the axle rather than concentrated at a single point. The two claw flaps close together under the driving force of the first drive component, thereby providing the clamping force for transporting the axle.

[0013] After gripping the axle, the stop mechanism rotates under the drive of the second drive mechanism, causing the first frame to extend between the tire mounting portions on both sides of the axle. The first telescopic rods on both sides of the first frame extend until they abut against the tire mounting portions. When the axle gripped by the mechanical claw is unstable, the axle will be locked onto the mechanical claw because the first telescopic rods abut against the tire mounting portions on both sides, making it less likely to slip.

[0014] Although the axle is less prone to slipping, the overall center of gravity is still unstable, so a counterweight is installed. The counterweight and stop are located on both sides of the housing width, allowing adjustment of the center of gravity along the housing width. The second frame of the counterweight is equipped with a second telescopic rod, which adjusts the distance between the counterweight and the second frame. By controlling the extension and retraction of the second telescopic rods on both sides by different lengths, the center of gravity along the length can be adjusted, making the overall center of gravity of the mechanical claw and axle more centered and less prone to tilting due to instability.

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

[0018] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The following detailed description illustrates the specific implementation method: Example 1 As attached Figures 1-5 As shown, a mechanical gripper for transporting a vehicle axle includes a housing 1. Mechanical gripper bodies 2 are provided on both sides of the bottom length direction of the housing 1. The mechanical gripper body 2 includes two gripper segments 201. An arc groove 203 is provided at the end of the gripper segment 201 away from the housing 1. The inner side of the gripper segment 201 is covered with a rubber anti-slip layer 204. A first driving member 202 for driving the gripper segments 201 to close is bolted on the housing 1. The first driving member 202 is a hydraulic cylinder.

[0021] A stop 3 is rotatably connected to one side of the housing 1 in the width direction. A second drive 303, which is a motor, is provided on the housing 1 to drive the stop 3 to rotate. The stop 3 includes a first frame 301. A first telescopic rod 302 is provided on both sides of the end of the first frame 301 away from the housing 1. A rubber pad 304 is provided on the end of the first telescopic rod 302 away from the first frame 301. A counterweight 4 is bolted to the side of the housing 1 away from the stop 3. The counterweight 4 has a weight similar to that of the stop 3. The counterweight 4 includes a second frame 401. A second telescopic rod 402 is provided on both sides of the end of the second frame 401 away from the housing 1. Both the first telescopic rod 302 and the second telescopic rod 402 are cylinders. A counterweight block 403 is bolted to the output shaft of the second telescopic rod 402.

[0022] After machining, the axle takes on a dumbbell shape, heavier at both ends and lighter in the middle. When gripping the axle, the mechanical claws 2 of the housing 1 grip it. The two mechanical claws 2 are located on both sides of the axle's centerline, clamping the axle so that the clamping force is applied more evenly to the axle rather than concentrated at a single point, making it easier for the axle to maintain balance. The two claw flaps 201 are brought together by the driving force of the first driving member 202, thereby providing the clamping force for transporting the axle.

[0023] The end of the claw 201 away from the housing 1 is provided with an arc groove 203. The arc groove 203 enables the mechanical claw 2 to make the clamping contact more closely fit the shape of the axle, thereby increasing the stability during clamping. The rubber anti-slip layer 204 on the inner side of the claw 201 can improve the friction during clamping, further reducing the probability of slippage.

[0024] After gripping the axle, the stop 3 rotates under the drive of the second drive 303, causing the first frame 301 to extend between the tire mounting portions on both sides of the axle. The first telescopic rods 302 on both sides of the first frame 301 extend until they abut against the tire mounting portions. When the axle gripped by the mechanical claw 2 is unstable, the axle will be locked onto the mechanical claw 2 because the first telescopic rods 302 abut against the tire mounting portions on both sides, making it less likely for the axle to slide against the mechanical claw 2.

[0025] Although the axle is less prone to slipping, the overall center of gravity is still unstable, so a counterweight 4 is installed. The counterweight 4 and the stop 3 are located on both sides of the housing 1 in the width direction, and can adjust the center of gravity in the width of the housing 1. The second frame 401 of the counterweight 4 is equipped with a second telescopic rod 402. The second telescopic rod 402 can adjust the distance between the counterweight 403 and the second frame 401. In this way, by controlling the extension and retraction of the second telescopic rods 402 on both sides by different lengths, the center of gravity in the overall length direction can be adjusted, so that the center of gravity of the whole consisting of the mechanical claw 2 and the axle is more centered and less prone to tilting due to instability.

[0026] In the width direction, the weight of the counterweight 4 and the stop 3 are similar, which can effectively reduce the shift of the center of gravity. At the same time, in the width direction, the axle is directly constrained by the claw flap 201 and is not prone to slippage.

[0027] Example 2 The difference from the above embodiment is that a pressure trigger switch 305 is provided on the side of the rubber pad 304 away from the first frame 301. The pressure trigger switch 305 is model QPM11-NC and is electrically connected to the second telescopic rod 402.

[0028] The pressure trigger switch 305 can detect the contact pressure between the second telescopic rod 402 and the axle. When the pressure reaches a certain value, it indicates that the second telescopic rod 402 has made full contact with the axle. At this time, the pressure trigger switch 305 will close the second telescopic rod 402 to control the extension of the second telescopic rod 402 and avoid excessive contact pressure that could scratch the axle.

[0029] Example 3 The difference from the above embodiment is that an arc-shaped buckle 205 is rotatably connected to one side of the claw flap 201, and a third driving member 206 is provided on the claw flap 201 to drive the arc-shaped buckle 205 to rotate. The third driving member 206 is a motor, and the arc-shaped buckle 205 is used to support the bottom of the axle after rotation.

[0030] After the mechanical claw 2 grabs the axle, the arc-shaped buckle 205 will rotate under the drive of the third drive component 206, so that the arc-shaped buckle 205 is fastened to the bottom of the axle, supporting the bottom of the axle, increasing the load-bearing capacity in the direction of gravity, and making the axle less likely to slide downward.

[0031] Example 4 The difference from the above embodiment is that a projection lamp 5 is bolted to the middle section of the bottom of the housing 1.

[0032] When gripping and seizing a vehicle axle, if the mechanical claw 2 is not symmetrical with respect to the center of the axle, the center of gravity of the axle and the mechanical claw 2 may become misaligned after gripping. Therefore, a projection light is provided at the bottom center of the housing 1. During gripping, the user can observe the projection position of the projection light to determine the relative position of the mechanical claw 2 and the axle, reducing the probability of the center of gravity becoming misaligned during gripping.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
