specific Embodiment approach 1

[0019] Specific implementation mode one: as Figure 1~3 As shown, the abrasive belt grinding tool installed at the end of the robot in this embodiment includes a drive wheel 1, a synchronous belt 2, a servo motor 4, a low-friction cylinder 5, a tensioner bracket 6, a tensioner 7, a frame 8, and a motor support Plate 9, transition wheel 10, servo electric cylinder 11, abrasive belt 12, contact wheel bracket 13, high-precision sensor 14 and contact wheel 15; tensioner 7 is installed on the upper end surface of frame 8 through tensioner bracket 6, low The friction cylinder 5 is fixed on the frame 8 and is located under the tensioner bracket 6, the driving wheel 1 is installed on the bottom of the frame 8, the servo electric cylinder 11 is installed horizontally on the bottom of the frame 8, and the motor support plate 9 is fixed on the frame 8 On the front end face, the servo motor 4 is fixedly mounted on the motor support plate 9, the output shaft of the servo motor 4 is connect...

specific Embodiment approach 2

[0025] Specific implementation mode two: as figure 1 As shown, the two sides of the transition wheel 10 in this embodiment are provided with annular ribs. With such a design, the ribs on both sides of the transition wheel 10 can correct the deviation of the abrasive belt 12 to ensure that the abrasive belt 12 is covered on the contact wheel 15 . Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0026] Specific implementation mode three: as figure 1 and figure 2 As shown, the contact wheel 15 in this embodiment is a cylindrical helical rubber wheel. With this design, the toothed rubber wheel can buffer the contact force between the contact wheel and the workpiece to be processed. Compared with the straight tooth structure, the helical tooth structure is easier to form a uniform contact force. At the same time, the design of this rubber wheel increases the friction between the contact wheel and the abrasive belt. force to prevent the abrasive belt from slipping on the contact wheel. Other compositions and connections are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a belt sanding tool installed at the tail end of a robot, and relates to a polishing tool. With the belt sanding tool installed at the tail end of the robot, the problem that an existing polishing tool for a robot is high in force control difficulty, requirement on control system performance, and cost is solved. A belt tensioner is installed on the upper end face of a framethrough a belt tensioner support. A low-friction air cylinder is fixedly installed on the frame and located below the belt tensioner support. A servo electric cylinder is horizontally installed at the bottom of the frame. A motor supporting plate is fixedly installed on the front end face of the frame. An output shaft of a servo motor is in transmission connection with a driving wheel through a synchronous belt. A contact wheel is connected to the servo electric cylinder through a contact wheel support. A high-precision sensor is installed on the contact wheel. The high-precision sensor is electrically connected with the servo electric cylinder. A transition wheel is installed in the middle of the frame. An abrasive belt is installed on the driving wheel, the belt tensioner and the contact wheel in sequence. The transition wheel is arranged on the part, between the belt tensioner and the contact wheel, of the abrasive belt in a pressing manner. The belt sanding tool installed at the tail end of the robot is used for aerospace product manufacturing and automobile making grinding.

Description

technical field [0001] The invention relates to an abrasive belt grinding tool, in particular to an abrasive belt grinding tool installed at the end of a robot. Background technique [0002] As a commonly used technology, grinding is widely used in various fields of manufacturing industries such as aerospace product manufacturing and automobile manufacturing with its irreplaceable technical characteristics. However, the grinding work is intensive, the working environment is harsh, and it needs experienced workers to complete it. Most of the domestic industries rely on manual grinding. For the application of grinding automation, the most commonly used is the grinding application based on the robot, which is mainly divided into two ways. One way is to use the end effector of the robot as the grinding tool. The processing of the blade is the most typical application. The grinding wheel and other grinding tools are fixed at the end of the robot. The workpiece to be processed is...
