Precision Assembly Robot

Abstract

The invention discloses a robot for precise assembling. The robot for precise assembling comprises a base, a rotary table, a large arm, a small arm, a wrist joint, a front end rotational joint and a pneumatic clamping device. The rotary table is rotationally installed on the base. One end of the large arm is hinged to the rotary table, and the other end of the large arm is hinged to one end of the small arm. The other end of the small arm is hinged to one end of the wrist joint, and the front end rotational joint is rotationally installed at the other end of the wrist joint. The pneumatic clamping device is installed at the outer end of the front end rotational joint. A rotary table ball screw driving mechanism used for driving the rotary table to rotate is installed on the base, a large arm ball screw driving mechanism used for driving the large arm to rotate is installed on the rotary table, a small arm ball screw driving mechanism used for driving the small arm to rotate is installed on the large arm, a wrist joint driving mechanism used for driving the wrist joint to rotate is installed on the small arm, and a front end joint driving mechanism used for driving the front end rotational joint to rotate is installed on the wrist joint. The robot for precise assembling is stable in transmission, high in positioning precision and production efficiency, long in service life and wide in application range.

Description

technical field [0001] The invention relates to a robot used in a fully automatic assembly line, in particular to a precision assembly robot driven by a high-precision ball screw. Background technique [0002] Over the past few years, with the continuous development of industrial technology, a large number of welding, casting, painting, handling, assembly and other occasions in the industrial field have begun to use robots to replace manual operations. In addition, robots have also begun to be used in the military, ocean exploration, aerospace, medical agriculture, forestry, and even service and entertainment industries. Robots have become one of the important and indispensable automation equipment that replaces manpower. At present, robots are mainly used in the automotive industry, electromechanical telecommunications industry, general machinery industry, metal processing, casting and other sectors in the industrial field. The industrial applications of robots are divided ...

Problems solved by technology

In view of the shortcomings of imported industrial robots, such as complex structure, inconvenient maintenance, and high price, imported brand industrial robots have a rather complicated structure. Due to the compact layout, it is difficult to disassemble during maintenance. An embarrassing situation where you dare not move, dismantle, or repair

In addition, imported industrial robots are expensive, costing hundreds of thousands or millions of dollars and expensive maintenance costs in the later period, which are unbearable pains for some small and medium-sized enterprises; they have a strong desire to be equipped with robots, but they have no desire to introduce expensive imported robots. strength
