Problems solved by technology

However, during the working process, due to the rotation of the working shaft, the lubricating oil smeared on the working shaft may be thrown out, causing the lubricating oil to contaminate other parts of the manipulator, resulting in unstable operation of the contaminated parts or other effects

Embodiment Construction

[0021] Such as Figure 1 to Figure 3 As shown, the manipulator includes a base 10 , a boom 11 rotatably connected to the base 10 , and a small arm 1 rotatably connected to the boom 11 . The forearm 1 is provided with a working shaft 2, and the forearm 1 is also provided with a motor 3 and a reducer 4. The rotor 3a of the motor 3 is connected to the input end of the reducer 4, and the output end of the reducer 4 is connected to the working shaft 2.

[0022] The forearm 1 is also provided with a screw mandrel 12, and a connecting piece 13 is arranged between the screw mandrel 12 and the working shaft 2. When the screw mandrel 12 rotates, the screw mandrel 12 drives the working shaft 2 to move up and down through the connecting piece 13.

[0023] The working shaft 2 is relatively fixed with a support 5 in the circumferential direction. Specifically, the working shaft 2 is covered with a spline bushing 8 , and the arm 1 is fixed with a connecting frame 16 . The connecting frame 1...

Abstract

The invention discloses a manipulator, and belongs to the technical field of manipulators, which solves the problem of instable running of the existing manipulator. The manipulator comprises a small arm, wherein a vertical screw rod and a working shaft are arranged on the small arm; the working shaft is parallel with the screw rod; a cover is fixedly arranged on the small arm, and the screw rod and the working shaft are positioned at the inner side of the cover; a connecting part is arranged between the working shaft and the screw rod, the working shaft is fixedly arranged on the connecting part along the axial direction, and the connecting part is connected with the screw rod, and is driven by the screw rod to drive the working shaft to move along the working shaft in the axial direction. The manipulator is characterized by comprising a magnet I and a hall sensor I, wherein the magnet I is fixedly arranged corresponding to the connecting part; the hall sensor I corresponds to the magnet I and is fixedly arranged corresponding to the small arm. Compared with the prior art, the manipulator has the advantage that by correspondingly arranging the magnet and the hall sensor with relative displacement, the displacement of the working shaft can be detected, and the displacement detection result is used for the displacement calibration and limiting of the working shaft, so that the working of the manipulator is more stable and safer.

Description

technical field [0001] The invention belongs to the technical field of manipulators, and relates to a manipulator. Background technique [0002] During the operation of the horizontal joint manipulator, the working shaft at the end rotates and moves up and down. In general, in order to ensure the smooth movement of the working shaft, the working shaft is coated with lubricating oil. But in the working process, because the working shaft rotates, the lubricating oil smeared on the working shaft may be thrown out, causing the lubricating oil to pollute other parts of the manipulator, causing the contaminated parts to run unstable or have other effects. Contents of the invention [0003] Aiming at the above problems, the present invention proposes a working shaft with better oil-proof effect, and its purpose can be realized by the following scheme: [0004] The manipulator includes a small arm and a working shaft arranged on the small arm. It is characterized in that the sma...
