They have a certain degree of automation and can rely on their own power and control capabilities to achieve various industrial processing and manufacturing functions. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals. Industrial manipulators are automatic devices that imitate human hand movements and can automatically grasp, carry and operate according to given programs.

[0003] The existing industrial robot working manipulator structure consists of a mechanical arm and a clamping mechanism. The manipulator is assembled at the working position, and the objects are grasped and transported through the clamping claws on the clamping mechanism. However, there are the following defects:

[0004] (1) In the process of grabbing and transporting objects through the gripper of the existing industrial robot working manipulator structure, the clamping component is prone to generate excessive clamping force and clamp on the object, causing damage to the object;

[0005] (2) During assembly of the existing industrial robot working manipulator structure, a bolt assembly is used to fix the base of the manipulator structure. However, during operation, the manipulator generates vibrations, which easily cause the bolt assembly on the base to spin, causing the assembly of the industrial robot working manipulator structure to loosen. For this reason, we propose an industrial robot working manipulator structure. Utility Model Content

[0006] The purpose of the utility model is to provide an industrial robot working manipulator structure to solve the problem that the industrial robot working manipulator structure proposed in the above background technology is prone to excessive squeezing force and cannot stop clamping in time, causing damage to the object, and at the same time, when bolts are used for assembly and installation, it is easily affected by the vibration force generated by the manipulator and is prone to self-spin loosening.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The utility model assembles a pressure sensor equipped with a movable pressure block on the clamping jaw. When clamping and transporting an object, the clamping jaw clamps the object and exerts a squeezing effect on the movable pressure block, transmitting the squeezing force to the pressure sensor. The pressure sensor monitors the pressure value and transmits it to the analysis module for analysis. When the analyzed pressure value is greater than the set maximum value, the control module issues an instruction to the clamping servo control module of the robot arm to stop applying the clamping force in time, effectively avoiding the clamping force of the utility model from being too large due to the inability to monitor the clamping force in time, resulting in excessive squeezing and damage to the object. The designed key module is used to encrypt the instructions, thereby improving the security of the instructions issued by the utility model.

[0017] (2) Through the designed installation shaft and clamping plate, the utility model uses a bolt assembly to penetrate into the base installation hole for fixing, and then the clamping groove at the end of the clamping plate is clamped in the side of the screw head of the bolt assembly. Since the clamping groove is a polygonal structure, it is adapted to fit the screw head of the bolt assembly, thereby locking and fixing the installation structure of the utility model to prevent the utility model from loosening due to self-spin. Through the designed assembly seat and push frame, the structure of the end of the clamping plate is reinforced. Through the designed spring, the spring exerts an elastic force on the push frame, and one end of the clamping plate is clamped more tightly on the end of the bolt assembly for installation under the action of elastic squeezing, thereby further improving the locking effect of the utility model. Through the designed limit block and limit groove, the push frame is limited to prevent it from detaching from the assembly seat. Through the designed ball bearing, a lubrication effect is played to reduce the wear between the installation shaft and the clamping plate. BRIEF DESCRIPTION OF THE DRAWINGS
