Technical Field

[0001] The utility model relates to the technical field of industrial robot clamps, in particular to an industrial robot composite clamp. Background Art

[0002] At present, in the industrial production process, production lines mainly use a large number of industrial robots to complete the processing and production of various workpieces. Industrial robots can automatically complete work according to preset programs, which not only replaces manpower but also greatly improves labor productivity.

[0003] The industrial robot composite clamp in the prior art mainly relies on mechanical transmission, and a push rod is used to push multiple clamp arms to rotate. The clamp arms contact the workpiece during the rotation process, thereby clamping the workpiece. However, due to the different sizes of workpieces, point contact often occurs during the clamping process, especially when clamping round workpieces, resulting in unstable clamping and easy falling off.

[0024] An industrial robot composite fixture, comprising

[0025] A mounting plate 20, which is used to connect with an external robot;

[0026] A push rod 10 is fixed to the upper surface of the mounting plate 20, and a telescopic rod of the push rod 10 is slidably extended to the bottom of the mounting plate 20 to provide kinetic energy to the composite clamp;

[0027] A clamping arm 30, which is annularly arranged outside the mounting plate 20 and is rotatably connected to the mounting plate 20;

[0028] The push plate 40 is arranged at the bottom side of the telescopic rod of the push rod 10 and is fixedly connected thereto. When the push rod 10 is working, the push plate 40 can be driven to move up and down;

[0029] The second connecting rod 50 is annularly arranged outside the push plate 40 and is rotatably connected to the push plate 40, and the other end of the second connecting rod 50 is rotatably connected to the clamp arm 30;

[0030] The composite clamping unit is arranged inside the clamping arm 30 and is used for composite clamping of the workpiece, increasing the stress points of the workpiece and preventing the workpiece from loosening.

[0031] Specifically, Figure 2 As shown in the figure: a chamber is provided inside the clamp arm 30, the side of the chamber is open, and the composite clamping unit is arranged inside the chamber. In this way, the composite clamping unit can be stored inside the chamber when not in use, so that the clamp arm 30 is more convenient for clamping the workpiece.

[0032] Specifically, Figure 2-4 As shown in: the composite clamping unit includes a driving motor 33, the driving motor 33 is fixedly connected to the clamping arm 30, and the output shaft of the driving motor 33 is fixedly connected to the active bevel gear 37, the outer surface of the active bevel gear 37 is meshed with the driven bevel gear 36, and the interior of the driven bevel gear 36 is fixedly connected to the screw rod 32, both ends of the screw rod 32 are rotatably connected to the clamping arm 30, and the outer surface of the screw rod 32 is spirally connected with an internal threaded sleeve 35, the outer surface of the internal threaded sleeve 35 is rotatably connected with a connecting rod 38, and the other end of the connecting rod 38 is rotatably connected to the auxiliary arm 34, and one end of the auxiliary arm 34 is rotatably connected to the clamping arm 30. In this way, when the clamping arm 30 clamps the workpiece, the driving motor 33 drives the active bevel gear 37 to rotate, thereby driving the driven bevel gear 36 to rotate, further driving the screw rod 32 to rotate, driving the internal thread block 35 to move, and pushing out the auxiliary arm 34, thereby clamping the workpiece, increasing the contact points between the workpiece and the device, and maintaining the stability and preventing the workpiece from falling off.
