Polishing tool

Abstract

The invention provides a polishing tool. The polishing tool comprises a tool main head and a polishing female head. The tool main head is used for being connected with an industrial robot and comprises a sealing cover and a driving mechanism, and an opening is formed in the lower end of the sealing cover. The polishing female head is provided with abrasive materials used for polishing. The polishing female head is mounted on the sealing cover, and the surface of a workpiece is polished through the opening in the lower end of the sealing cover. The driving mechanism is connected with and drives the polishing female head. Air suction connectors are arranged on the lower portion of one side face of the front-back side of the sealing cover and located on the polishing powder generation side and face the space above the outer side of the sealing cover. The left side and the right side of the sealing cover are each connected with a displacement sensor. A dust escape preventing component is connected to the periphery of the opening in the lower end of the sealing cover. By adoption of the polishing tool, the problems that the polishing efficiency of the surfaces of large curved-surface parts is low, the polishing quality is poor, and the dedusting effect is poor are effectively solved, and the polishing tool is intelligent equipment which can achieve automatic polishing and automatic replacement of the abrasive materials, allows the robot to participate in cooperation, and can achieve centralized dedusting.

Description

technical field [0001] The invention relates to a special tool, in particular to a grinding tool for a robot to automatically grind large parts. Background technique [0002] With the continuous improvement of people's living standards and environmental improvement requirements, the operation of enterprises in the grinding process has gradually changed from manual operation to mechanical automation and even to intelligent development. For the surface of large parts, such as the surface of wind power blades, the surface of ships, the surface of aviation aircraft, the surface of automobile body, etc., it is characterized by large surface area and huge grinding workload, which is a labor-intensive industry. The research and development cost of equipment is high and difficult, so this type of special grinding equipment is still in a blank state in China.

Problems solved by technology

For the surface of large parts, such as the surface of wind power blades, the surface of ships, the surface of aviation aircraft, the surface of automobile body, etc., it is characterized by large surface area and huge grinding workload, which is a labor-intensive industry. The research and development cost of equipment is high and difficult, so this type of special grinding equipment is still blank in China

[0003] The use of this kind of grinding equipment in China is still in a semi-automatic state. At present, there are two kinds of pneumatic eccentric grinding tools and hand-held electric grinding tools. The characteristics of the two grinding tools are: small grinding area, frequent replacement of sandpaper , low efficiency, poor dust removal effect
