Mechanical arm for mounting of spring in machine and working method of mechanical arm

Abstract

A mechanical arm for mounting of spring in a machine comprises a base, a first mechanical arm body, a second mechanical arm body, a mechanical hand, a drive device and a control device. The mechanical hand comprises a left spring clamping jaw, a right spring clamping jaw, a pair of left auxiliary clamping jaw and right auxiliary clamping jaw and a detection claw, wherein the left spring clamping jaw and the right spring clamping jaw are arranged oppositely, and the left auxiliary clamping jaw and the right auxiliary clamping jaw are arranged oppositely. The left spring clamping jaw, the right spring clamping jaw, the left auxiliary clamping jaw and the right auxiliary clamping jaw each comprise an upper clamping jaw body, a lower clamping jaw body and a clamping jaw joint connected with the upper clamping jaw body and the lower clamping jaw body. An electromagnetic chuck is arranged between the left spring clamping jaw and the right spring clamping jaw. A pressure sensor is arranged at the end of the detection claw. The first mechanical arm body, the second mechanical arm body and the mechanical hand are all connected with the drive device. The electromagnetic chuck, the pressure sensor and the drive device are all connected with the control device. By means of the design, manpower is replaced for mounting the spring, production efficiency is greatly improved, and the problem that the spring in the machine is hard to mount is solved.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a mechanical arm for installing internal springs of machines. Background technique [0002] Due to the complex installation environment of the spring, the installation method is often changed. At present, the installation of the spring is mostly manual installation. Viewfinders also greatly affect production efficiency, and the installation quality is not easy to guarantee; in addition, when the spring force required to install the spring is large, manual operation is more difficult, which requires an automated spring installation system to replace manual installation. operation, and can cope with the complex installation environment of the spring. [0003] In addition, the spring installation may be unqualified, or the spring force may not meet the standard after installation, which requires effective testing after the installation is completed, but ordinary position te...

Problems solved by technology

[0004] The purpose of the invention: the present invention discloses a mechanical arm for installing the internal spring of the machine, which can replace the manual spring installation, greatly improve the production efficiency, solve the problem that the internal spring of the machine is not easy to install, and can deal with complex actual situations; after the installation is completed , directly detect the spring force, once the installation is detected to be unqualified, it will be reinstalled automatically

This design replaces the manual installation of springs, which greatly improves production efficiency and solves the problem of difficult installation of springs inside the machine; the combination of electromagnetic suction cups and spring jaws makes it more convenient to grab springs and the installation process is more reliable; the design of auxiliary jaws It can cope with complex actual situations and help installation; after the installation is completed, the pressure sensor will detect the spring force, and once the installation is detected to be unqualified, the control device will issue an instruction to automatically reinstall
