Chip absorbing and cooling connecting piece used for boring end effector

Abstract

The invention discloses a chip absorbing and cooling connecting piece used for a boring end effector, which is installed on the front plate of the supporting unit of the boring end effector. The chip absorbing and cooling connecting piece comprises a pressure head pipe casing, an A nozzle, a B nozzle and a pressure foot, wherein, the structure of the A nozzle is identical with that of the B nozzle; the A nozzle and the B nozzle are respectively installed in an A threaded hole and a B threaded hole at the upper part at the front end of the pressure head pipe casing, and the rear end of the pressure head pipe casing is installed in the counter sink of the pressure foot. The chip absorbing and cooling connecting piece is provided with two nozzles, can realize the switch between the cooling modes and cooling mediums in one drilling process, such as the gas cooling mode can be switched to the liquid cooling mode, or a cutting fluid can be switched to another cutting fluid, and switching is useful particularly when laminating materials consisting of different materials are processed.

Description

technical field [0001] The present invention relates to a chip suction and cooling connection for a drilling end effector. Background technique [0002] Hole machining plays an important role in aerospace manufacturing, and it is reported in the literature that about 40 million holes are drilled each year on an assembly line of a wing. Traditional manual drilling has heavy workload, boring process, low drilling efficiency, difficulty in ensuring consistency of hole accuracy and quality, and high labor and material costs for mass production. With the improvement of the robot's position accuracy, load capacity and the development of position and stiffness compensation technology, the robot can be used as an efficient mobile platform, and combined with the drilling end effector, a flexible drilling system can be formed, which improves productivity, and It reflects the concept of lean system. The end effector is a key part of the drilling robot system that directly contacts th...

Problems solved by technology

[0003] Chips and cutting heat will be generated during drilling. In a non-closed cutting environment, chips will pollute the operating environment and affect the quality of the machined surface. Excessive rotation will also cause chips to splash and hurt people, and dusty chips will also endanger The health of the operator; cutting heat is not good for the tool, accelerates the wear of the tool, and affects the quality and cost of drilling

At present, chips still need to be manually removed to varying degrees, which is in contradiction with the development direction of automation and numerical control of machining equipment

Although the cooling device has basically become a standard configuration in automation equipment, its working state is mostly exposed to the environment. The cooling medium is affected by the cutting heat and may produce harmful gases or small droplets, which will pollute the environment and at the same time health of the operator
