Embodiment Construction

[0051] A preferred embodiment of a horizontally articulated mechanical arm of the present invention is Figures 2 to 6 shown, including:

[0052] A pedestal 20 is provided for fixed arrangement on the ground or a fixed plane, and the pedestal 20 is fixedly provided with a first shaft motor 21, and the first shaft motor 21 drives a first drive shaft 211 to rotate, and the first drive shaft 211 extends along a vertical direction Y, and the vertical direction Y is defined as the horizontal direction X. The first driving shaft 211 is combined with a first reduction mechanism 22, so that the first shaft motor 21 passes through the first The reduction mechanism 22 outputs power.

[0053] A first arm 30, one end is combined with the first reduction mechanism 22 on the first shaft motor 21, so that the first arm 30 is combined with the first shaft motor 21, then the first arm 30 can be controlled by the first shaft motor 21. The first axis motor 21 drives the rotation, and makes the...

Abstract

The invention discloses a horizontal joint mechanical arm. Mainly, a first arm body is driven through a first shaft motor on a base to rotate in the horizontal direction; a second shaft motor is further arranged on a second arm body, the second arm body is combined with the first arm body, and the second arm body is driven through the second shaft motor to rotate in the horizontal direction; a third rod-shaped shaft linear motor is further fixedly arranged on the second arm body to serve as a driving source for linear displacement in the vertical direction; a linear motor rotor of the third rod-shaped shaft linear motor is further in linkage with a fourth shaft motor, and the fourth shaft motor can be used for driving to achieve displacement in the vertical direction and driving a rotary rod at the same time, and thus three rotating momentums and one vertical displacement momentum are provided; in addition, driving sources of all movement momentums are all direct transmission type independent driving sources, in this way, the driving precision and the driving instantaneity can be remarkably improved, and components needing to be configured through an indirect transmission way can be further simplified; furthermore, maintenance cost and warranty cost can be reduced at the same time, and added value is increased.

Description

technical field [0001] The invention relates to a horizontal joint mechanical arm, which is related to the structure of the mechanical arm. Background technique [0002] SCARA (SelectiveComplianceAssemblyRobotArm) selects a robot arm with compliance in the direction, which is a widely used planar articulated robot arm. Since the robot arm has three horizontal rotation joints and one vertical displacement joint, it can be used for simultaneous horizontal positioning. And the operation of vertical displacement or rotation drive. [0003] And the general planar articulated mechanical arm 10 such as figure 1 As shown, it mainly includes setting a first motor 111 on a base 11 to drive the large arm 12 to rotate horizontally with the first rotating shaft 112; In the big arm 12, the second rotating shaft 132 can drive the small arm 13 to rotate horizontally; a third motor 133 and a screw 134 are arranged in the small arm 13, and the third motor 133 drives a third rotating shaft 1...
