Problems solved by technology

[0003] The purpose of the present invention is to provide a robot end effector to solve the problem that the mechanical transmission chain of the industrial robot in the prior art has backlash, which causes the motor to move backlash when the mechanical arm changes the direction of motion, resulting in drilling processing. Technical Issues with Reduced Accuracy

specific Embodiment approach

[0030] Furthermore, please also refer to figure 1 and figure 2 , as a specific embodiment of the robot end effector provided by the present invention, the connection assembly 3 further includes a sliding plate 31 fixedly connected to the mounting part 32 and the slider 23 respectively, and the sliding plate 31 is slidably arranged on the casing 4 . The connection assembly 3 is used to connect the main shaft module 1 and the feed module 2, the installation part 32 in the connection assembly 3 is fixedly connected with the main shaft housing 13, the sliding plate 31 and the slider 23 in the connection assembly 3 are fixedly connected, wherein the installation part 32 and The sliding plate 31 is also fixedly connected, so the sliding block 23, the sliding plate 31 and the mounting part 32 move synchronously. The casing 4 is arranged on the outside of the lead screw 22. The sliding connection between the sliding plate 31 and the casing 4 can not only protect the lead screw 22, b...

Abstract

The invention provides a robot end executor. The robot end executor comprises a spindle module, a feeding module and a connecting assembly; the spindle module comprises a spindle and a spindle shell wrapping the periphery of the spindle, the feeding module comprises a screw, a feeding motor driving the screw to rotate and a sliding block fixed to the screw, a machine shell is arranged on the outer side of the screw, the connecting assembly comprises a mounting part fixed to the spindle shell, and the mounting part is fixedly connected with the sliding block. According to the robot end executor, rotation motion of the feeding motor is converted into the linear motion of the spindle through the screw, the influence caused by the reverse gap in a robot transmission chain can be avoided, and the machining precision is improved.

Description

technical field [0001] The invention belongs to the field of processing equipment, and more specifically relates to a robot end effector. Background technique [0002] In the processing of large parts, industrial robots can replace large machine tools to drill large parts. The industrial robot changes the movement direction of its own mechanical arm through the mechanical transmission chain. During the multiple drilling process of the robot, due to the backlash in the mechanical transmission chain, when the mechanical arm changes the movement direction, it will cause the motor to run idle. The arm does not move with the rotation of the motor, and the mechanical transmission chain produces a backlash, which causes the drilled hole to not be a complete circle, reducing the accuracy of the robot's drilling process. Contents of the invention [0003] The purpose of the present invention is to provide a robot end effector to solve the problem that the mechanical transmission c...
