Abstract

The invention discloses a robot fixture with spring self-locking devices, relates to the technical field of robot fixtures, and solves the problems of high cost, easy wear and deformation of a lock piece of a locking mechanism, reduction of the equipment use rate and increment of the maintenance cost in a traditional robot fixture. A connecting arm is vertically arranged; a movable arm and a fixedarm are vertically arranged on one side of the connecting arm in sequence from top to bottom; a cylinder is vertically arranged between the movable arm and the fixed arm; a piston rod of the cylinderis connected with the movable arm; two sets of spring self-locking devices are vertically arranged on two sides of the cylinder; the upper parts of the spring self-locking devices are connected withthe lower end surface of the movable arm; and an in-place detecting mechanism is mounted on the connecting arm. The robot fixture is used for workpiece clamping in a burr removing machine and cleanerequipment.

Description

technical field [0001] The invention relates to the technical field of robot clamps, in particular to a robot clamp with a spring self-locking device. Background technique [0002] The existing robot clamp cylinders use special cylinders with end locks, and the clamps are locked after the clamp clamps the workpiece and the locking cylinder is cut off. The initial design cost of this clamp is large. Due to the wear and deformation of the sheet, the frequency that the robot fixture cannot be opened smoothly increases, and non-professionals cannot repair the cylinder model, and the maintenance cost of the equipment increases accordingly. [0003] To sum up, the existing robotic fixtures have the problems of high cost, and the locking plate of the locking mechanism is prone to wear and deformation, resulting in reduced equipment utilization and increased maintenance costs. Contents of the invention [0004] The purpose of the present invention is to solve the problems that th...
