Description

Technical Field

[0001] The utility model relates to the technical field of grinding mechanical arms, in particular to a grinding mechanical arm which is flexible in use. Background Art

[0002] The grinding robot arm can make intelligent adjustments based on real-time data to ensure the stability of processing quality. It can avoid errors and fatigue problems in manual operation, improve production efficiency and the stability of product quality. In addition, the grinding robot arm can also move at high speed, achieve fast processing speed, and save labor costs. Future prospects. With the continuous development of industrial automation, the application of grinding robot arms in the field of fine processing will become more and more extensive. In the future, the grinding robot arm is expected to achieve higher polishing accuracy and faster processing speed, and may be linked with other intelligent devices to achieve more efficient production processes and finer processing effects. In addition, the application of grinding robot arms in fields such as medical care and home services will also become more in-depth and popular.

[0003] The grinding robot arm is controlled in real time by the central control equipment, so that the grinding speed can be reduced, but new problems will also arise, mainly from the grinding disc. Because when the robot arm uses the grinding disc, in order to shorten the grinding time, there is almost no idle time period during the grinding. Therefore, the grinding disc itself will be in a high-speed grinding state for a long time, thereby increasing the temperature of the grinding disc itself. Long-term high temperature will greatly reduce the service life of the grinding disc, and then the grinding robot arm will speed up the scrapping of the grinding disc compared with manual grinding. In order to solve this technical problem, the utility model proposes a convenient-to-use grinding robot arm. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The bearing plate 1 can provide a load-bearing function for the entire device and the parts to be polished.

The three grinders 5 are clamped at 45° Angle array, motor 1 4 can drive three grinders 5 to rotate with the output end as the center of the circle. Motor 1 4 is an existing servo motor, which can accurately drive any one of the three grinders 5 to keep parallel with the supporting plate 1. When a single grinder 5 continues to grind for more than a specified time, motor 1 4 can drive the grinder 5 to rotate, so that another grinder 5 replaces the grinder 5 that is just grinding, so that the grinding disc on the grinder 5 can have sufficient time to cool down, thereby solving the problem of shortening the service life of the grinding disc due to long-term high temperature.

[0023] The outer surface of the supporting plate 1 is fixedly connected to a slide rail 6, the outer surface of the slide rail 6 is slidably connected to a load-bearing wheel 7, the outer surface of the load-bearing wheel 7 is rotatably connected to a wheel frame 8, the outer surface of the wheel frame 8 is fixedly connected to a supporting frame 19, the outer surface of the supporting frame 19 is fixedly connected to a work frame 9 and a limit frame 10, the work frame 9 and the limit frame 10 can move in a fixed direction given by the slide rail 6 through the wheel frame 8 and the load-bearing wheel 7, thereby further increasing the grinding area of ​​the equipment, and can also adjust different moving distances for grinding parts of different lengths, making the equipment more flexible and practical when used.

[0024] The outer surface and inner wall of the limit frame 10 are slidably connected to the lifting frame 11, and a positioning wheel 12 is installed inside the lifting frame 11. The outer surface of the positioning wheel 12 is slidably connected to the outer surface of the work frame 9. A load-bearing platform 13 is installed on the outer surface of the lifting frame 11, and the outer surface of the robot arm 2 is rotatably connected to the outer surface of the load-bearing platform 13.

A bearing is installed on the outside of the supporting frame 17, and the outer ring of the bearing is fixedly connected to the outer surface of the guard frame 18, thereby making the supporting frame 17 more stable when rotating or stationary.

[0028] The grinders 5 are all installed on the outer surface of the supporting frame 17. The angles of the three grinders 5 are all maintained at forty-five degrees. There are three grinders 5. The supporting frame 17 can only rotate 45° each time. The three grinders 5 can be switched so that only one grinder 5 can be used normally. When it is necessary to grind a grinding workpiece with an angle of 45°, the time for adjusting the grinder 5 can be reduced, thereby making the equipment more stable during use.
