[0030] Example:

[0031] The present application embodiment discloses a palletizing robot that is easy to maintain. Figure 1 , Figure 2 and Figure 3 , including a palletizing robot body 1, a fixing frame 3 is installed on the palletizing robot body 1, a gripping assembly 2 is detachably connected to the inner side of the fixing frame 3, the gripping assembly 2 includes a driving assembly 21 and a clamping assembly 22, the driving assembly 21 includes a mounting plate 216, a sliding hole 214 is provided on the mounting plate 216, a sliding rod 213 is fixedly connected to the upper side of the sliding hole 214, a bidirectional screw rod 212 is rotatably connected to the lower side of the sliding hole 214, two sliding blocks 215 are symmetrically slidably connected to the inside of the sliding hole 214, a mounting groove 6 is provided on the surface of the sliding block 215, and the sliding rod 213 and the bidirectional screw rod 212 are respectively located above and below the mounting groove 6;

[0032] The second motor 224 is fixedly connected to the inside of the installation slot 6, and the two sliding blocks 215 are symmetrically slidably connected to the outside of the sliding rod 213, and the two sliding blocks 215 are symmetrically threadedly sleeved on the outside of the bidirectional screw rod 212. The outside of the mounting plate 216 is fixedly connected with the first motor 211 for driving the bidirectional screw rod 212 to rotate. The first motor 211 is controlled to drive the bidirectional screw rod 212 to rotate. The rotation of the bidirectional screw rod 212 makes the two sliding blocks 215 slidably sleeved on the outside of the sliding rod 213 move relatively inside the sliding hole 214, thereby driving the two clamping plates 221 to move relatively to clamp and fix the object;

[0033] A groove is provided on the surface of the fixing frame 3, and the motor 1 211 is arranged inside the groove. The clamping assembly 22 includes a motor 224 fixedly connected to the surface of the sliding block 215, and the output end of the motor 224 is fixedly connected to a rotating shaft 225, and the front end of the rotating shaft 225 is fixedly connected to a fixing plate 223, and the surface of the fixing plate 223 is fixedly connected to a clamping plate 221, and the opposite side surfaces of the two clamping plates 221 are provided with clamping grooves 222, and the clamping grooves 222 are arranged in a "V" shape.

[0034] When it is necessary to clamp and fix a square object, the control motor 224 is operated to drive the rotating shaft 225 to rotate, thereby driving the fixing plate 223 and the clamping plate 221 to rotate, so that the opposite side of the two clamping plates 221 is a plane. When it is necessary to clamp a round object, the control motor 224 is operated to make the opposite side of the two clamping plates 221 a clamping groove 222 with a "V"-shaped structure, so that the two inner walls of the clamping groove 222 are in contact with the surface of the round object to achieve four-point clamping of the round object, thereby ensuring the clamping and fixing effect of the object. The inner wall of the clamping groove 222 and the surface of the clamping plate 221 are fixedly connected with an anti-slip rubber pad (not shown in the figure). The design of the anti-slip rubber pad improves the firmness of clamping the object.

[0035] See also Figure 1 and Figure 2 The outer side of the mounting plate 216 is symmetrically fixedly connected to the limiting block 32, the inner wall of the fixing frame 3 is symmetrically provided with a limiting groove 31 adapted to the limiting block 32, the limiting block 32 is provided with a limiting hole 321, and the top of the fixing frame 3 is symmetrically provided with a threaded hole connected to the limiting groove 31, the internal thread of the threaded hole is inserted with a limiting bolt 7, the lower end of the limiting bolt 7 extends to the inside of the limiting hole 321, and the limiting bolt 7 is screwed so that the limiting bolt 7 is moved out from the inside of the limiting hole 321, thereby releasing the limit on the limiting block 32, and the limiting block 32 can be moved out from the inside of the limiting groove 31, so that the clamping assembly 2 can be disassembled from the fixing frame 3 to facilitate the maintenance of the clamping assembly 2.

[0036] See also Figure 2 and Figure 3 An annular groove 4 is provided on the surface of the sliding block 215, and an annular slide plate 5 is rotatably connected inside the annular groove 4. The front end of the annular slide plate 5 is fixedly connected to the inner surface of the fixed plate 223. When the rotating shaft 225 drives the fixed plate 223 to rotate, the fixed plate 223 drives the annular slide plate 5 to rotate inside the annular groove 4, thereby improving the stability of the fixed plate 223 during rotation.

[0037] The implementation principle of the embodiment of the present application is as follows: when it is necessary to clamp and fix a square object, the second motor 224 is controlled to drive the rotating shaft 225 to rotate, thereby driving the fixing plate 223 and the clamping plate 221 to rotate, so that the opposite side of the two clamping plates 221 is a plane; when it is necessary to clamp a round object, the second motor 224 is controlled to work, so that the opposite side of the two clamping plates 221 is a clamping groove 222 with a "V"-shaped structure, so that the two inner walls of the clamping groove 222 are in contact with the surface of the round object, so as to achieve four-point clamping of the round object, thereby ensuring the clamping and fixing effect of the object, so as to select a suitable clamping surface according to the shape of the object to be clamped;

[0038] Then, the motor 1 211 is controlled to work and drive the bidirectional screw rod 212 to rotate. The rotation of the bidirectional screw rod 212 causes the two sliding blocks 215 slidably sleeved on the outside of the sliding rod 213 to move relatively inside the sliding hole 214, thereby driving the two clamping plates 221 to move relatively to clamp and fix the object.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
