Description

Technical Field

[0001] The utility model relates to the technical field of manipulators, in particular to a manipulator clamp for a manipulator which is easy to install. Background Art

[0002] As an intelligent device that can work semi-autonomously, robots are widely used in many fields, especially in industrial production. In the manufacturing industry, the robot's manipulator can realize automatic loading, unloading, handling and grasping quickly and accurately, significantly improving production efficiency compared to traditional manual labor.

[0003] In order to make the robot manipulator adapt to various production needs, it is often necessary to select a specific manipulator for the robot. The manipulator and the mechanical arm of a traditional robot are mostly fixed by a flange. A large number of bolts need to be turned during the replacement process, resulting in low efficiency in the installation and disassembly of the manipulator, which is not conducive to the needs of efficient production. Therefore, a robot manipulator fixture that is easy to install is needed to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a robot manipulator clamp which is easy to install, so as to solve the problem that the manipulator of the robot arm is inconvenient to replace in the prior art.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a robot manipulator clamp that is easy to install, comprising a shell and a clamping jaw, a first rotating shaft is provided at the front end of the shell, a first axial hole is provided on the clamping jaw, the shell and the clamping jaw are slidably connected through the first rotating shaft and the first axial hole, a telescopic cylinder is provided in the shell, a sliding groove is provided at the front end of the telescopic cylinder, a sliding rod is provided on the side end face of the clamping jaw, the clamping jaw and the telescopic rod are slidably connected through the sliding rod and the sliding groove, a fixed claw is provided at the end of the shell away from the clamping jaw, a second axial hole is provided on the side end face of the fixed claw, a second rotating shaft is provided at the end of the shell away from the first rotating shaft, the fixed claw and the shell are rotatably connected in cooperation with the second rotating shaft through the second axial hole, and a locking sleeve is provided on the outer end face of the shell.

[0006] Preferably, the number of the fixing claws is 3-6, and the fixing claws are arranged in an equidistant circular array along the axis of the shell, and the fixing plate is grasped by multiple groups of fixing claws to ensure the stability of the connection.

[0007] Preferably, the inner end surface of the fixing claw away from the locking sleeve is provided with a barb, and the flange is hooked by the barb, so as to facilitate the cooperation between the manipulator and the mechanical arm.

[0008] Preferably, the inner end surface of the fixing claw away from the barb is a sloped structure, and the outer end surface of the locking sleeve close to the fixing claw is a conical structure, so that when the locking sleeve approaches the fixing claw, the inner end surface of the fixing claw is squeezed, so that the barb is clamped on the outer end surface of the robot arm flange.

[0009] Preferably, the inner end surface of the locking sleeve is provided with an internal thread, the locking sleeve is connected to the housing via threads, and the position of the locking sleeve is adjusted by rotating the locking sleeve.

[0010] Preferably, a torsion spring is provided on the second rotating shaft, and the fixing claw is elastically connected to the housing via the torsion spring, so that after the locking sleeve slides upward, the fixing claw close to the barb end automatically expands outward, thereby facilitating the removal of the manipulator.

[0011] Preferably, the inner wall width of the slide groove is equal to the diameter of the slide rod, thereby ensuring the stability of the clamp and preventing the clamp from shaking when grasping.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model cooperates with the fixing claw and the locking sleeve so that the fixing claw clamps the flange of the robot arm, thereby facilitating the fixation of the robot arm and the manipulator. The threaded locking sleeve structure facilitates quick manual tightening to limit and fix the fixing claw, thereby preventing the manipulator from falling off and improving the convenience of replacing the manipulator.

[0014] 2. The utility model uses a torsion spring to enable the fixing claw to open automatically after the locking sleeve is removed, thereby facilitating the quick disassembly of the manipulator and the arm, further improving the convenience of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
