[0002] During the process of machining automotive molds in a factory, it is often necessary to transport some heavy molds from a storage lathe to a stamping lathe. The main function of this device is to realize the automatic transportation and automatic loading between the sheet metal buffer area and two stamping lines, and to automatically lock the pallet and the vehicle body during this period. For example, in the "Scissor Claw of an Industrial Robot" with the publication number "CN215395300U", although this scissor claw of the industrial robot has a certain buffering and protective effect when clamping fragile items, its structural complexity makes assembly and maintenance difficult, increasing production costs and maintenance difficulties; in terms of durability, sliding parts and return springs are prone to wear and fatigue, affecting the accuracy and stability of the claw and shortening the service life; it is difficult to control the clamping force, and high skills are required for operators; there are limitations in adaptability, and it is difficult to meet the clamping requirements of items with different shapes, sizes, and materials; moreover, its complex structure and buffering mechanism may limit the movement speed and efficiency of the claw, affecting the overall working efficiency of the industrial robot. At the same time, in an automated production line, AGVs are often used for material transportation and positioning docking. Traditional AGV docking devices usually adopt manual or semi-automatic locking methods, which have problems such as low positioning accuracy, complex operation, and low efficiency. Therefore, there is an urgent need for a new solution in the prior art to solve the existing problems. Summary of the Invention

[0003] In order to solve the problems existing in the prior art, the present invention provides a heavy-duty AGV device with an automatic locking function.

[0025] The present invention is further described in detail below with reference to the accompanying drawings.

[0026] The present invention provides a heavy-duty AGV device with an automatic locking function for connecting the docking vertical shaft of a pre-assembly table, as Figures 1 - 3 shown, including:

[0027] A servo motor 12;

[0028] A speed reducer 7, connected to the servo motor 12, for reducing the rotational speed and increasing the output torque;

[0029] An electric cylinder 8, connected to the servo motor 12 and the speed reducer 7, for converting the rotational motion of the servo motor 12 into a linear motion;

[0030] A fixing plate 10, fixedly connected to the housing of the electric cylinder 8;

[0031] A sliding pin groove 11, provided on the fixing plate 10;

[0032] A connecting block 14, connected to the push rod 13 of the electric cylinder 8;

[0033] A sliding pin 1, provided on the connecting block 14 and movably arranged in the sliding pin groove 11,

[0034] A left clamping jaw 5 and a right clamping jaw 3, arranged oppositely, for clamping or releasing the docking vertical shaft. The left clamping jaw 5 and the right clamping jaw 3 are simultaneously hinged to a rotating shaft 13, and the rotating shaft 13 is provided on the fixing plate 10; the clamping surfaces of the left clamping jaw 5 and the right clamping jaw 3 should be machined into an arc shape matching the docking vertical shaft to increase the contact area during clamping.

[0035] A left clamping plate 4, one end of which is hinged to the left clamping jaw 5 and the other end is hinged to the connecting block 14; the length of the left clamping plate 4 matches the movement range of the left clamping jaw 5 to ensure that the left clamping jaw 4 can completely clamp or release the docking vertical shaft.

[0036] A right clamping plate 6, one end of which is hinged to the right clamping jaw 3; the other end is hinged to the connecting block 14; the length and installation method of the right clamping plate 6 are symmetrical to those of the left clamping plate 4.

[0037] The push rod 13 drives the connecting block 14 to reciprocate, and the connecting block 14 drives the left clamping jaw 5 and the right clamping jaw 3 to clamp or release the docking vertical shaft through the left clamping plate 4 and the right clamping plate 6.

[0038] When the AGV arrives at the pre-assembly station, the servo motor 12 starts. The speed is reduced and the output torque is increased through the reduction gear 7, driving the electric cylinder 8 to convert the rotary motion into a linear motion. The push rod 13 pushes the connecting block 14 inward, and the connecting block 14 moves linearly in the sliding pin groove 11 through the sliding pin 1. The movement of the connecting block 14 is transmitted to the left clamping jaw 5 and the right clamping jaw 3 through the left clamping plate 4 and the right clamping plate 6, causing the left clamping jaw 5 and the right clamping jaw 3 to rotate around the rotating shaft 13 to clamp the docking vertical shaft. When it is necessary to release the docking vertical shaft, the servo motor 12 runs in reverse, and the push rod 13 pushes the connecting block 14 outward. The connecting block 14 drives the left clamping jaw 5 and the right clamping jaw 3 to rotate reversely around the rotating shaft 13 through the left clamping plate 4 and the right clamping plate 6 to release the docking vertical shaft.

[0039] It also includes a floating joint 2. The connecting block 14 is connected to the push rod 13 through the floating joint 2. The design of the floating joint 2 can absorb the small deviation between the push rod 13 and the connecting block 14, ensuring that the linear motion of the push rod 13 will not be disturbed.

[0040] The floating joint 2 includes a hollow floating body 21 and a floating locking part 22. The floating body 21 is connected to the connecting block 14, and one end of the floating locking part 22 is movably arranged in the floating body 21, and the other end is connected to the push rod 13.

[0041] It also includes a fixing frame 9 for fixing. The fixing frame 9 is made of high-strength steel to ensure that it can bear the weight of the heavy-duty AGV and the impact force during the docking process. The fixing frame 9 is fixedly connected to the AGV body through bolts.

[0042] There are two fixing plates 10, symmetrically arranged on both sides of the connecting block 14.

[0043] The coordinated work of the servo motor 12, the electric cylinder 8 and the reduction gear 7 mainly provides precise power control through the servo motor 12, reduces the speed and increases the output torque through the reduction gear 7, and the electric cylinder 8 converts the rotary motion into a linear motion, jointly realizing efficient, precise and stable movement control of the push rod 13 to meet the precise requirements of speed, position and torque of this fixture during work.

[0044] The push rod 13 makes a linear motion in the cylinder diameter to push the floating joint 2 and the sliding pin 1. The floating joint 2 is mainly used to absorb the eccentricity and angular error between the servo motor 12 and the driven body, ensuring stable connection between the two without high-precision coaxiality, effectively preventing damage to the cylinder seal ring, reducing interference phenomena, and improving production efficiency and operation safety.

[0045] The movement of the push rod 13 drives the sliding pin 1 to move linearly within the sliding pin groove 11. When driving the connecting block 14 to move backward, it drives the left clamping plate 4 and the right clamping plate 6 backward, causing the left clamping jaw 5 and the right clamping jaw 3 to close and clamp the vertical shaft at the docking place of the pre-installation table. When driving the connecting block 14 forward, it drives the left clamping plate 4 and the right clamping plate 6, causing the left clamping jaw 5 and the right clamping jaw 3 to open and release the vertical shaft at the docking place of the loose installation table.

[0046] The floating joint 2 consists of two parts: a floating main body 21 and a floating locking component 22. The floating main body 21 is a hollow cylindrical structure with sliding or rolling elements designed inside to allow a certain degree of movement and rotation, used to compensate for displacements caused by factors such as temperature changes and mechanical vibrations between connecting components, reducing stress and wear. The floating locking component 22 includes locking screws or bolts for fixing the floating main body 21 to prevent excessive movement. During system operation, the floating joint achieves displacement compensation, stress release, and vibration absorption through the coordinated action of these two parts, thereby improving the stability and reliability of the system and extending the service life of the equipment.

[0047] Finally, it should be noted for the present invention that the above embodiments have elaborated in detail on the technical solutions of the present invention and are not limited only to the foregoing embodiments. Those of ordinary skill in the art should understand that modifying or replacing the features and parameters in the foregoing embodiments does not depart from the spirit and scope of the technical solutions of the foregoing embodiments.
