[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1-5 One embodiment provided by the present utility model:

[0025] A chassis of an industrial robot, comprising:

[0026] A main body, including an installation platform 1, an installation screw 11 fixedly connected to the surface of the installation platform 1, a first nut 12 threadedly connected to the surface of the installation screw 11, a mounting plate 13 arranged on the surface of the installation platform 1, a base 14 arranged on the surface of the mounting plate 13, and a robot arm 15 fixedly connected to the surface of the base 14. The installation platform 1 and the installation screw 11 form a chassis of an industrial robot, which can realize the connection with the installation platform 1 and the installation and support of the industrial robot;

[0027] The connecting mechanism includes a movable groove 2 which is opened inside the mounting plate 13. The surface of the mounting plate 13 is provided with a sliding groove 21 and a moving groove 22. The surface of the movable groove 2 is slidably connected with a movable block 23. The surface of the movable block 23 is fixedly connected with a sliding plate 24 and a sliding block 25. The surface of the movable block 23 is provided with a first engaging groove 26, and the surface of the sliding plate 24 is provided with a second engaging groove 27. Both sides of the movable groove 2 and the sliding groove 21 are arc-shaped, so that after the mounting screw 11 penetrates through the mounting plate 13, its surface can better engage with the sliding groove 21.

[0028] Furthermore, there are four groups of the movable groove 2 and the sliding groove 21. The four groups of movable grooves 2 are opened at the four ends of the mounting plate 13. The size of the movable groove 2 is larger than that of the sliding groove 21. The number of each group of sliding grooves 21 is two, and each group of sliding grooves 21 is opened on both sides of the movable groove 2. By changing the mounting hole into the movable groove 2 and the sliding groove 21, the installation of the mounting screw 11 becomes more convenient, and there is no need to precisely connect with a round-hole type mounting hole.

[0029] Furthermore, there are two groups of sliding plates 24. The two groups of sliding plates 24 are fixedly connected to both sides of the movable block 23. The sliding plates 24 are slidably connected to the surface of the sliding groove 21, and the sliding blocks 25 are slidably connected to the surface of the moving groove 22. Under the action of the sliding plates 24, when the first nut 12 is installed, its surface can be in contact with both the mounting plate 13 and the sliding plates 24, increasing the contact area with the first nut 12, so as to prevent the position of the mounting plate 13 from shifting on the sliding groove 21 due to the vibration of the industrial robot during the installation and fixation of the mounting plate 13. Through the connection between the sliding blocks 25 and the moving grooves 22, the movement of the sliding blocks 25 can drive the movement of the movable blocks 23 and the sliding plates 24.

[0030] Furthermore, the sizes of the first engaging groove 26 and the second engaging groove 27 are the same. The first engaging groove 26 and the second engaging groove 27 are engaged and connected to the surface of the mounting screw 11. The movable block 23 and the sliding plate 24 are respectively engaged with the mounting screw 11 through the first engaging groove 26 and the second engaging groove 27, so as to achieve a more tightly and firmly connected effect with the mounting screw 11.

[0031] Furthermore, a rotating mechanism is provided on the surface of the mounting platform 1. The rotating mechanism includes a fixing plate 3 which is fixedly connected to the surface of the base 14. A rotating groove 31 is opened inside the fixing plate 3, and an arc-shaped groove 32 is opened on the surface of the fixing plate 3. A rotating plate 33 is fixedly connected to the surface of the mounting platform 1. A short screw 34 is fixedly connected to the surface of the rotating plate 33, and a second nut 35 is installed on the surface of the short screw 34. Through the connection between the fixing plate 3 and the base 14, the mounting platform 1 and the base 14 can be disassembled, and the effect of rotating the base 14 can be achieved.

[0032] Furthermore, the fixing plate 3 is rotatably connected to the surface of the installation platform 1. There are two sets of arc-shaped grooves 32, which are opened on both sides of the fixing plate 3. The cross-sections of the rotating grooves 31 and the rotating plates 33 are in a "T" shape. The rotating plates 33 are rotatably connected to the surfaces of the rotating grooves 31. Under the connection action of the rotating plates 33 and the rotating grooves 31, the base 14 and the robotic arm 15 rotate around the rotating plates 33 as the center.

[0033] Furthermore, the short screw 34 is slidably connected to the surface of the arc-shaped groove 32. The size of the second nut 35 is larger than that of the arc-shaped groove 32. The second nut 35 is threadedly connected to the surface of the short screw 34. The second nut 35 is abutted and connected to the surface of the fixing plate 3. Under the connection action of the short screw 34 and the second nut 35, the position of the rotated fixing plate 3 can be fixed.

[0034] Working principle: When installing the chassis, first push the sliding block 25 to make the movable block 23 and the sliding plate 24 respectively abut against the movable groove 2 and the sliding groove 21 on the sides away from the first abutting groove 26 and the second abutting groove 27, and penetrate the installation screw 11 into the movable groove 2 and the sliding groove 21. At this time, rotate the entire installation plate 13 to make the installation screw 11 abut against the sliding groove 21 away from the sliding plate 24. Then, move the sliding block 25 again to make it slide on the moving groove 22, so that the movable block 23 and the sliding plate 24 slide on the movable groove 2 and the sliding groove 21 respectively, making the first abutting groove 26 and the second abutting groove 27 abut against the surface of the installation screw 11. Finally, threadedly connect the first nut 12 to the installation screw 11 and make it abut against the sliding plate 24 and the installation plate 13.

[0035] When the industrial robot needs to operate in different directions, first rotate the base 14 on the chassis to drive the fixing plate 3 to rotate on the surface of the installation platform 1, and then drive the rotating plate 33 to rotate on the surface of the rotating groove 31, so that the short screw 34 slides on the surface of the arc-shaped groove 32. After rotation, threadedly install the second nut 35 on the surface of the short screw 34 and make it abut against the surface of the fixing plate 3 to complete the rotation of the chassis angle.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
