Description

Technical Field

[0001] This invention relates to the field of highway slope reinforcement technology, specifically a large-scale free-form surface robotic grinding system. Background Technology

[0002] Currently, the grinding and polishing of large free-form surfaces is mostly done manually by hand using tools and relying on experience. This makes it difficult to maintain uniform grinding pressure and grinding path, which seriously affects the grinding quality of the product. At the same time, for large workpieces, the manual grinding speed is limited, resulting in low processing efficiency. Moreover, the grinding and polishing environment is harsh, which seriously threatens the health of workers.

[0003] Currently available equipment cannot effectively handle the debris generated during grinding. Firstly, when grinding and polishing large workpieces, a large amount of debris remains on the workpiece surface. Then, during subsequent grinding, the debris gets stuck between the grinding head and the workpiece, which may cause scratches on the workpiece surface, affecting grinding accuracy and effect. Secondly, the debris generated during grinding can cause splashing, posing a safety hazard to operators. Thirdly, after grinding, the debris fills the operating space, making cleaning tedious and increasing the labor intensity of cleaning personnel. Summary of the Invention

[0014] In summary, the present invention has the following main beneficial effects:

[0015] 1. This invention utilizes a motor output shaft, a conical chamber, conical blades, a fixed block, a grinding head, and suction holes, all working in concert. The motor output shaft drives the conical chamber and its internal conical blades, fixed block, and grinding head to rotate. During polishing of the workpiece surface, the debris generated by the grinding head is drawn into a collection box through multiple suction holes by the negative pressure generated by the rotating conical blades. Lighter air particles are filtered out through a filter screen, while heavier debris particles are discharged from the lower chip outlet pipe into an external collection device. This allows for timely and concentrated collection of grinding debris, preventing debris residue from scratching the workpiece surface, improving grinding precision and smoothness, and enhancing processing quality.

[0016] 2. This invention utilizes the coordinated operation of a motor output shaft, a conical tube chamber, conical blades, a fixed block, a grinding head, suction holes, and a chip discharge pipe. The negative pressure generated by the rotation of the conical blades draws the debris into a collection box through multiple suction holes, while heavier debris particles are discharged from the chip discharge pipe into an external collection device. This can, to some extent, prevent a large amount of debris from splashing and affecting the safety of operators, while also enhancing the cleanliness of the operating environment and reducing the labor intensity of cleaning personnel.

[0017] 3. This invention uses the cooperation of the third bolt, slot, insert, and reinforcing sleeve to loosen and pull out the third bolt, then loosen and remove the reinforcing sleeve, and then pull the insert along with the grinding head out of the slot to complete the disassembly. Installation is the reverse, which improves replacement efficiency and reduces costs by only using the grinding head. Attached Figure Description

[0043] Please refer to this carefully. Figure 1 , 23, 9, The right end face of the grinding head 310 is fixedly connected with multiple sets of grinding teeth 311.

[0045] Please refer to this carefully. Figure 1 , 2 The output end of the grinding motor 120 is rotatably connected to the shaft of the collection box 220 and fixedly connected to the shaft of the conical tube 230.

[0046] The output end of the grinding motor 120 is rotatably connected to the shaft of the collection box 220 and fixedly connected to the shaft of the conical tube 230, which can drive the connecting component 200 and the replacement component 300 to rotate, making it more efficient and saving energy.

[0047] Please refer to this carefully. Figure 1 , 2 One end of the grinding motor 120 is fixedly connected to the main body 110 of the grinding robot.

[0048] One end of the grinding motor 120 is fixedly connected to the main body 110 of the grinding robot, which can drive the grinding head 310 to grind and polish the workpiece from various angles and directions.

[0049] In use, the motor output shaft first drives the conical tube chamber 230 and the internal conical blades 260, fixed block 240, and grinding head 310 to rotate. When the grinding head 310 polishes the surface of the workpiece, the debris generated is sucked into the collection box 220 by the negative pressure generated by the rotation of the conical blades 260 through multiple suction holes 312. The lighter air rises and is filtered and discharged through the filter screen, while the heavier debris particles are discharged from the chip outlet pipe 222 below to the external collection device. This can collect the debris generated by grinding in a timely manner, which can prevent debris from remaining on the surface of the workpiece, avoid scratching the workpiece, improve the grinding accuracy and smoothness of the workpiece, and improve the quality of workpiece processing.

[0050] Secondly, the device uses the negative pressure suction generated by the rotation of the conical blades 260 to draw the debris into the collection box 220 through multiple suction holes 312, and discharges the heavier debris particles from the debris discharge pipe 222 into the external collection device. This can, to a certain extent, prevent a large number of debris particles from splashing and affecting the safety of the operators, and can also enhance the cleanliness of the operating environment and reduce the labor intensity of the cleaning personnel.

[0051] When replacing the grinding head 310, simply loosen and pull out the third bolt 314, then loosen and remove the reinforcing sleeve 320, and then pull the insert block 313 along with the grinding head 310 out of the slot 241 to complete the disassembly. The installation is the reverse. Replacing only the grinding head 310 can reduce the cost of use. All parts not mentioned in this device are the same as or can be implemented using existing technology.
