[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] As Figures 1-4 shown, a self-pressure-holding rotary grinding device provided by the present invention includes: a working stroke cylinder 1, a high-speed rotating motor 2, a grinding bracket 3, a cylinder mounting seat 4, a sheet metal frame fixing plate 5, a pressure-holding stroke cylinder 6, a right-angle pneumatic joint 7, a grinding disc 8, a grinding connection block 9, a high-speed rotating motor bracket 10, a grinding frame base 11, a grinding frame plug 12, a slide block 13, and a cylinder mounting plate 14.

[0025] The working stroke cylinder 1 is installed on the cylinder mounting plate 14. The cylinder mounting plate 14 and the working stroke cylinder 1 form a cylinder assembly mechanism. The grinding frame plug 12 is fixedly connected to the bottom of the cylinder mounting plate 14. The cylinder assembly mechanism is connected to the robot through the grinding frame plug 12. The cylinder assembly mechanism can be quickly and conveniently replaced through the grinding frame plug 12, enabling the robot to meet various working requirements, realizing the convenience of device disassembly, and allowing the grinding device to be disassembled faster and other devices to be installed for different work.

[0026] The slide block 13 is installed on the working stroke cylinder 1. One side of the sheet metal frame fixing plate 5 is fixedly connected to the slide block 13, and the grinding bracket 3 is fixedly connected to the other side of the sheet metal frame fixing plate 5. The grinding bracket 3 and the slide block 13 are fixedly connected through the sheet metal frame fixing plate 5, which can stably fix and support. The horizontal movement of the slide block 13 is controlled by the working stroke cylinder 1, and the stroke is 0 - 2000 mm.

[0027] The cylinder mounting seats 4 are respectively fixedly connected to the upper and lower ends inside the grinding bracket 3. The pressure-holding stroke cylinder 6 is installed between the two cylinder mounting seats 4. The pressure-holding stroke cylinder 6 is installed in the grinding bracket 3 through the cylinder mounting seats 4. The pressure-holding stroke cylinder 6 is jointly fixed by the grinding bracket 3 and the cylinder mounting seats 4. The upper and lower two cylinder mounting seats 4 prevent the pressure-holding stroke cylinder 6 from generating vibration and offset when starting to work, affecting the working position and the load imbalance of the entire mechanism, and at the same time preventing the risk of the pressure-holding stroke cylinder 6 and the connected mechanism from falling.

[0028] One end of the grinding connection block 9 is fixed to the pressure-holding stroke cylinder 6, and a high-speed rotation motor bracket 10 is installed at the other end. The pressure-holding stroke cylinder 6 and the high-speed rotation motor bracket 10 are fixedly connected through the grinding connection block 9, and the motor and the grinding disc mechanism are carried by the grinding connection block 9. The grinding connection block 9 is installed on the pressure-holding stroke cylinder 6 to form an integral body, and the pressure-holding stroke cylinder 6 drives the grinding connection block 9 to move up and down.

[0029] The high-speed rotation motor 2 is installed on the high-speed rotation motor bracket 10. The grinding frame base 11 is fixedly connected below the high-speed rotation motor bracket 10. The grinding frame base 11 is connected to the grinding disc connecting rod through an extension shaft. The grinding disc 8 is installed on the grinding disc connecting rod. The extension shaft is connected to the high-speed rotation motor 2, and the extension shaft is controlled by the high-speed rotation motor 2. The grinding frame base 11 not only bears the weight but also prevents the splashing during the operation of the grinding disc 8 from interfering with and damaging the high-speed rotation motor 2. The size of the grinding disc 8 is Ф10 - 200mm.

[0030] After connecting the grinding device to the robot body through the grinding frame plug 12, professional operators supply air to the grinding device. Before the grinding device starts grinding, the pressure-holding stroke cylinder 6 starts to work and moves to the highest position to prevent the grinding disc 8 from colliding with the ground and being damaged when it starts to work, or to prevent the interference of the grinding disc with the pipe wall; when the pressure-holding stroke cylinder 6 is lifted to the highest point, the high-speed rotation motor 2 is powered on and starts to work, and the grinding disc 8 starts to rotate. The pressure-holding stroke cylinder 6 controls the grinding disc 8 to descend to the working position for grinding work. When the grinding disc 8 is working, the pressure-holding stroke cylinder 6 continuously generates pressure on the grinding disc 8 to ensure the grinding force; when the grinding disc 8 is worn, the stroke of the pressure-holding stroke cylinder 6 increases to ensure the grinding force between the grinding disc 8 and the contact surface; the slider 13 can be controlled by the operation stroke cylinder 1 to move so that the grinding disc 8 can move horizontally for grinding work. By controlling the slider 13 with the operation stroke cylinder 1, it can move on the same axis to control the grinding disc 8 to reach above the specified working position, greatly expanding the working range and freedom.

[0031] The present invention has been described in detail above in conjunction with the drawings and embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present invention. The content not described in detail in the present invention can all adopt the prior art.
