Robot handheld force control belt sander

Abstract

The invention belongs to the field of grinding equipment, and discloses a robot handheld force control belt sander which comprises a belt sander body; the belt sander body comprises a sanding belt, a grinding wheel, a tensioning wheel, a sanding belt driving wheel and a mounting base; the sanding belt is wound on the outer sides of the grinding wheel, the tensioning wheel and the sanding belt driving wheel, the mounting base comprises a front base plate, a rear base plate and a connecting plate, and the connecting plate is connected with the front base plate and the rear base plate; the grinding wheel is rotatably connected with a connecting plate at one end of the mounting base, two shaft ends of the sanding belt driving wheel are rotatably connected with one end of the front base plate and one end of the rear base plate respectively, the rear base plate is connected with a servo motor, the shaft end of the servo motor is connected with a driving synchronizing wheel, the shaft end of the sanding belt driving wheel is connected with a driven synchronizing wheel, and the driving synchronizing wheel is connected with the driven synchronizing wheel through a synchronous belt; and the tensioning wheel is rotatably connected to the other end of the mounting base, and a rotating shaft of the tensioning wheel is connected with a tensioning deviation adjusting mechanism. The sander is suitable for polishing large and heavy workpieces and is flexible in operation and compact in structure; the sanding belt linear speed control is accurate, and the driving torque output is constant; and the grinding precision is highly controllable.

Description

technical field [0001] The invention relates to the related field of grinding equipment, in particular to a robot hand-held force-controlled abrasive belt machine. Background technique [0002] Most of the existing belt machines are fixed belt machines, which use robots to grab workpieces and put them on the fixed belt machine for grinding operations. Due to the limitation of robot load and operating range, fixed belt machines are mostly suitable for small pieces of grinding operations. When encountering large and heavy workpieces for grinding operations, it is impossible to use robots to grab workpieces and put them on traditional fixed belt machines for grinding operations. At this time, a belt machine is provided that can change the working position and working state in real time to complete large The grinding operation of heavy workpieces has become particularly important, and the handheld abrasive belt machine of the robot is favored by the industry.

[0002] Most of the existing belt machines are fixed belt machines, which use robots to grab workpieces and put them on the fixed belt machine for grinding operations. Due to the limitation of robot load and operating range, fixed belt machines are mostly suitable for small pieces of grinding operations. When encountering large and heavy workpieces for grinding operations, it is impossible to use robots to grab workpieces and put them on traditional fixed belt machines for grinding operations. At this time, a belt machine is provided that can change the working position and working state in real time to complete large The grinding operation of heavy workpieces has become particularly important, and the handheld abrasive belt machine of the robot is favored by the industry. However, the existing belt abrasive machine has a large and heavy structure and cannot adapt to the flexible operation of the robot. After the type abrasive belt machine is combined with the robot, it is difficult to control the precision of grinding and polishing, and it is impossible to achieve high-precision grinding operations
