[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0027] Refer to Figure 1-5 , A horizontal handling robot arm suitable for high loads, including a base 1, a moment arm 2, and an operating arm 3. The base 1 includes a bottom plate 11, a casing 12, a motor A13, a central axis 14, a chassis 15 and a pillow block 16. The operating arm 3 includes a housing 31, a motor B32 and a connecting plate B33; wherein the housing 12 is mounted on the bottom plate 11, the motor A13 is mounted at one end of the housing 12, and the output shaft of the motor A13 is mounted with a gear A131, the middle shaft 14 is installed at the other end of the casing 12, and gear B141 and gear plate A142 are installed on the bottom shaft 14. Because the tooth surface of gear B141 meshes with the tooth surface of gear A131, the rotation of gear A131 can drive gear B141 to rotate, thereby driving The middle shaft 14 rotates, the chassis 15 is installed at the opening of the upper end of the casing 12, and the middle of the chassis 15 is provided with a shaft hole 151, the pillow block 16 is embedded in the shaft hole 151, and the bottom of the pillow block 16 is installed with a chainring B161, a chainring B161 It extends into the casing 12, and the tooth surface of the gear plate B161 meshes with the tooth surface of the gear plate A142, so the gear plate B161 can rotate with the rotation of the gear plate A142.

[0028] The motor A13 drives the gear A131 to rotate, thereby driving the gear B141 to rotate, while the gear B141 rotates to drive the center shaft 14 to rotate, which in turn drives the gear plate A142 to rotate; and the gear plate A142 rotates to drive the gear plate B161 that meshes with it to rotate. In turn, the pillow block 16 is driven to rotate.

[0029] The moment arm 2 is located at the upper end of the base 1, and one end of the moment arm 2 is provided with a circular groove 21, which corresponds to the pillow block 16, so one end of the pillow block 16 can be inserted into the circular groove 21; the other end of the moment arm 2 A main shaft 22 is provided, and a connecting plate A23 is installed on the main shaft 22; a cross pin hole 24 is also provided at one end of the moment arm 2, and the cross pin hole 24 communicates with the circular groove 21, and the cross pin hole 24 is inserted with a cross pin rod 4, In addition, one end of the cross pin 4 protrudes out of the circular groove 21 and is inserted into the cross slot 162 provided at one end of the pillow block 16 to be fixed.

[0030] One end of the pillow block 16 is connected to the moment arm 2 through the cross pin 4, so that when the pillow block 16 rotates, the power arm 2 will swing to achieve horizontal movement; and the cross pin 4 is used for the connection The fixing method can not only realize the connection between the pillow block 16 and the moment arm 2, but also is convenient and quick to disassemble and assemble. Compared with the fixing method by screws, it reduces the number of openings for the moment arm 2 and reduces the moment arm 2 Damage.

[0031] One end of the housing 31 is provided with a shaft groove 311. The shaft groove 311 corresponds to the main shaft 22. Therefore, one end of the main shaft 22 can be inserted into the shaft groove 311, and the connecting plate A23 is inserted into the shaft groove 311. The motor B32 is installed at one end of the housing 31. The output shaft of the motor B32 penetrates the inner wall of the housing 31 and extends into the shaft groove 311. The connecting disk B33 is installed on the output shaft of the motor B32, and the connecting disk B33 and the connecting disk A23 are connected by the screw 5.

[0032] The motor B32 drives the connecting plate B33 to rotate, thereby driving the connecting plate A23 to rotate, and the rotation of the connecting plate A23 will drive the main shaft 22 to rotate; and the motor B32 accompanying the rotation of the main shaft 22 will drive the housing 31 to swing, thereby expanding The horizontal movement range of the horizontal plane.

[0033] The four ends of the connecting plate A23 are provided with screw holes A231, and the four ends of the connecting plate B33 are provided with screw holes B331, and the screw holes A231 correspond to the screw holes B331 one by one, so the screw 5 is rotatably installed in the screw hole A231 and extends to the screw hole In B331; through this connection and fixing method, the connection between the connection plate A23 and the connection plate B33 is tightened, and it is easy to operate and convenient to assemble.

[0034] In order to better demonstrate the lateral handling process suitable for high-load lateral handling robot arms, this embodiment now proposes a lateral handling method for high-load lateral handling robot arms, including the following steps:

[0035] S1: Turn on the power of the motor A13, the motor A13 starts to drive the gear A131 to rotate, and the gear A131 rotates to drive the gear B141 to rotate, which in turn drives the middle shaft 14 to rotate; and the gear plate A142 that accompanies the rotation of the middle shaft 14 will drive it to mesh with it The chainring B161 rotates, which in turn drives the pillow block 16 to rotate.

[0036] S2: Because one end of the pillow block 16 is embedded in the circular groove 21 on the moment arm 2 and is fixed by the cross pin 4; therefore, when the pillow block 16 rotates, the power arm 2 rotates and swings, so the horizontal movement of the moment arm 2 is realized.

[0037] S3: After turning on the power of the motor B32, the motor B32 starts to drive the connecting disk B33 to rotate. Because the connecting disk B33 and the connecting disk A23 are connected by the screw 5, the connecting disk A23 rotates with the rotation of the connecting disk B33, and then drives the main shaft 22 Spin.

[0038] S4: With the rotation of the main shaft 22, the motor B32 is driven to rotate, which in turn drives the housing 31 to rotate and swing, thereby expanding the horizontal movement range of the lever arm 2 and thereby realize the lateral transport of goods through the operating arm 3.

[0039] The present invention proposes a horizontal transporting machine arm and method suitable for high loads. The motor A13 drives the gear A131 to rotate, and the rotation of the gear A131 will drive the gear B141 to rotate, which in turn drives the central shaft 14 to rotate; and the central shaft 14 rotates. The gear plate A142 will drive the gear plate B161 meshed with it to rotate, thereby driving the pivot table 16 to rotate; and when the pivot table 16 rotates, it will drive the power arm 2 to swing and swing to achieve horizontal horizontal movement.

[0040] The present invention proposes a horizontal handling robot arm and method suitable for high loads. The motor B32 drives the connecting disk B33 to rotate. The rotation of the connecting disk B33 will drive the connecting disk A23 to rotate, which in turn drives the spindle 22 to rotate; and with the spindle 22 The rotation of the motor B32 drives the rotation of the motor B32, which in turn drives the housing 31 to rotate and swing, so as to expand the horizontal movement range of the horizontal plane, and then realize the lateral transport of the goods through the operating arm 3.

[0041] To sum up: the present invention proposes a lateral handling robot arm and method suitable for high loads to realize the lateral movable handling function of the robot arm, and the lever arm 2 and the operating arm 3 are made of high-strength alloy steel plates. Thereby, it has the pressure-bearing capacity under high load, so it meets the diversified needs of enterprise production, thus effectively solving the existing technical problems.
