Problems solved by technology
[0005] The problem solved by the present invention is that the mechanical arm of carbon fiber material or carbon fiber composite material and the supporting part are screwed together with screws, and the screw loosening phenomenon is easy to occur during use, so that the operation accuracy of the mechanical arm is reduced, the work efficiency is low, and even the equipment may be damaged. Problems with failure or downtime

Embodiment Construction
[0026] Please refer to figure 1 The inventor found and analyzed that the cause of the problems such as reduced operation accuracy of the robot arm 12 and low work efficiency of the robot arm 12 is that the robot arm 12 and the supporting member 11 are screwed together with screws 13. Screw the screw 13 through the through hole 14 into the screw hole 15. The surface of the through hole 14 has no threads. The screw hole 15 is a blind hole (one end of the blind hole does not pass), and the threads in the screw hole 15 are mainly used for Clamp the screw 13 under tension. The rotating force or torque exerted on the thread of the screw hole 15 will stretch the screw 13 and generate tension, thereby generating a clamping load to fix the screw 13 at the screw hole 15. However, as the mechanical arm 12 is continuously carrying out load-bearing operations, the mechanical arm will bend and vibrate, and a small gap 16 appears between the screw 13 and the screw hole 15, so that the clampin...

Abstract
The invention relates to an assembling method of mechanical parts. The assembling method includes providing a first mechanical part made of carbon fiber materials or carbon fiber composites and provided with screw holes and providing a second mechanical part provided with through holes; coating glue at the bottom of screws; passing the screws after being glued through the screw holes and screwing the screws into the screw holes until the screw holes stop moving; standing still after the screw holes stop moving until glue solidifies into membrane to form a gel layer. With the assembling method of the mechanical parts, assembling strength of the screws and the screw holes is increased, screw loosening condition during load-bearing operation of mechanical arms is avoided, operating accuracy and working efficiency of the mechanical arms are improved, equipment failure or shutdown is avoided and operation is simple and convenient.
Description
Technical field [0001] The invention relates to the field of mechanical processing, in particular to a method for assembling mechanical parts. Background technique [0002] Robot is a precision machine device that automatically performs work. It is a product of advanced integration of cybernetics, mechatronics, computers, materials, and bionics. It has important uses in industries, medicine, agriculture, construction, and even military. Industrial robots can be proficient in cutting, grinding, welding and warehouse handling and other related tasks. The working part is mainly a mechanical arm. At present, this kind of robot is made of carbon fiber or carbon fiber composite material, which overcomes the disadvantages of heavy weight, poor mechanical properties such as stiffness and strength, low flexibility, high cost, and large investment. [0003] For example, in the Chinese patent document with the publication number CN102407524A (publication date: April 11, 2012), more relevant...
