Description

Technical Field

[0001] This utility model relates to the field of drive device technology, and in particular to an industrial robot joint drive device. Background Technology

[0002] With the advancement of industrial automation, more and more industrial robots are being applied to production lines. Industrial robots are generally formed by the cooperation of robot joints, limbs and corresponding gripping, holding and adsorption components. As the core of the robot, the joints and limbs are subject to high loads in actual operation, which places high demands on the drive of the joints.

[0003] While multi-degree-of-freedom industrial robots can perform more complex tasks, their prices have increased exponentially. Simple tasks often only require one or two degrees of freedom, but current robots have very complex structures, high construction and maintenance costs, and low cost-effectiveness when performing simple tasks. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an industrial robot joint drive device, which overcomes the shortcomings of the prior art and effectively solves the problems that the robot structure is very complex, the construction and maintenance costs are high, and the cost performance is low when performing simple movements.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

A connecting mechanism connects the support rod and the adjusting rod, and a steering mechanism is connected to one end of the adjusting rod. The connecting mechanism includes a push rod motor, a first connecting block and a second connecting block respectively connected to both ends of the push rod motor. The steering mechanism includes a mounting block, a second servo motor mounted on one side of the adjusting rod, a worm gear connected to the output shaft of the second servo motor, and a worm wheel meshing on one side of the worm gear.

[0007] The output shaft of the first servo motor drives the structure above the base to rotate through meshing gears. The extension and retraction of the push rod motor, in conjunction with the push rod motor, pushes and pulls the adjusting rod through the connector, the first connecting block, and the second connecting block, causing the adjusting rod to rotate up and down at the top of the support rod. The second servo motor drives the worm gear to rotate, and the rotating worm gear drives the connecting rod to rotate through the meshing worm wheel, causing the mounting block to rotate up and down at one end of the adjusting rod. This achieves the expected simple movement while also making the exposed parts easy to maintain, thus reducing costs.

[0008] Preferably, a first servo motor is installed on the top of the base, and the output shaft of the first servo motor and the rod wall of the rotating rod are both fitted with meshing gears.

[0009] The output shaft of the first servo motor drives the structure above the base to rotate through meshing gears.

[0010] Preferably, the first connecting block is fixed to one end of the outer wall of the fixed plate, and the second connecting block is fixed to the bottom of the adjusting rod.

[0011] The connecting mechanism is fixed between the support rod and the adjusting rod by the first connecting block and the second connecting block.

[0012] Preferably, both the first connecting block and the second connecting block are rotatably connected to a connector, and the two connectors are respectively fixed to both ends of the push rod motor.

[0013] Both the first connecting block and the second connecting block are rotated together with the push rod motor via connectors.

[0014] Preferably, one end of the mounting block is fixed with a connecting rod, and the connecting rod and the adjusting rod are in rotational engagement.

[0015] The mounting block is rotatably connected to one end of the adjusting rod via a connecting rod.

[0016] Preferably, the worm gear is sleeved and fixed to one end of the connecting rod wall, and the worm's rod wall is rotatably connected to a fixing block fixed to one side of the outer wall of the adjusting rod.

[0017] The worm gear is rotatably connected to one side of the adjusting rod by a fixed block, and the rotating worm gear drives the connecting rod to rotate through the meshing worm wheel.

[0018] The beneficial effects of this utility model are as follows:

[0019] The first servo motor drives the structure above the base to rotate. The extension and retraction of the push rod motor pushes and pulls the adjusting rod, causing the adjusting rod to rotate up and down at the top of the support rod. The second servo motor, through the meshing worm gear, causes the mounting block to rotate up and down at one end of the adjusting rod. This completes the expected simple movement while also making the exposed parts easier to maintain, reducing costs. It effectively solves the problems of existing robots having very complex structures, high construction and maintenance costs, and low cost-effectiveness when performing simple movements.
