[0016] See also Figure 1-4The utility model provides a technical solution: a grinding machine tool with a protective structure, including a base 1, a grinding table 2 is arranged on the top of the base 1, a frame 3 is arranged outside the grinding table 2, both sides of the bottom end of the frame 3 are welded and fixed to both sides of the top of the grinding table 2, a cylinder 6 is fixedly installed on the top of the frame 3 by bolts, a grinding mechanism 5 is arranged at the bottom of the frame 3, the grinding mechanism 5 is composed of a mounting plate, a motor and a grinding head, the output end of the cylinder 6 passes through the bottom of the top plate of the frame 3 and is fixedly connected to the mounting plate at the top of the grinding mechanism 5, and a guard 4 is arranged between the frames 3, the bottom end of the guard 4 is an open structure, the top of the guard 4 is provided with a through hole 8 matched with the grinding mechanism 5, and both sides of the front end of the frame 3 are provided with a U-shaped seat 9, and the upper and lower ends of the U-shaped seat 9 are It is fixedly connected to the front end of the frame 3 by bolts, a vertically distributed vertical axis 13 is provided inside the U-shaped seat 9, and a connecting sleeve 12 slidingly set on the outside of the vertical axis 13 is fixed on both sides of the shield 4, and a storage box 10 is provided on the top of the U-shaped seat 9, and the inner side of the storage box 10 is fixed to the outer side of the top of the U-shaped seat 9 by bolts. An elastic rope 11 is stored inside the storage box 10, and the outer end of the elastic rope 11 is connected to the hanging ring on the outside of the connecting sleeve 12 through a hook. When the cylinder 6 of this structure drives the grinding mechanism 5 to move downward inside the frame 3 to grind the workpiece on the grinding table 2, the grinding mechanism 5 will be synchronously linked to the shield 4 through the through-hole 8 when it is pushed forward, and the shield 4 will slide synchronously downward on the outside of the vertical axis 13 through the connecting sleeve 12 when the linkage is received. When the sleeve 12 slides, the elastic rope 11 is stretched with the cooperation of the storage box 10 until the shield 4 blocks the outside of the grinding table 2 at a suitable position to protect the metal scraps generated during the processing. When the cylinder 6 drives the grinding mechanism 5 to rise for recycling, the shield 4 will move upward synchronously under the elastic force of the elastic rope 11, so that the shield 4 can move in real time, so that the staff can disassemble and assemble the workpiece on the grinding table 2, etc., avoiding the trouble of the existing grinding machine tools usually fixing the shield 4 on the outside of the grinding table 2, which causes the staff to remove the shield 4 to disassemble and assemble the workpiece, etc., thereby improving the convenience of the staff during operation. The outer edge of the mounting plate at the top of the grinding mechanism 5 is welded and fixed with a pressure ring 7 , and the inner wall edge of the through-opening 8 is provided with a recessed portion matched with the pressure ring 7. When the grinding mechanism 5 of this structure is pushed downward, the pressure ring 7 can be driven to embed into the recessed portion of the inner wall edge of the through-opening 8, so as to realize the linkage effect on the shield 4, and the through-opening 8 can be sealed to prevent metal waste from flying out of the through-opening 8. The inner walls of both sides of the shield 4 are symmetrically welded and fixed with vertically distributed limit blocks 14, and the inner sides of the limit blocks 14 are bonded and fixed with extrusion pads, and magnet blocks 15 are embedded and installed between each group of limit blocks 14. The magnet blocks 15 of this structure can be embedded and installed between each group of limit blocks 14 and placed inside the shield 4. This allows the shield 4 to absorb a part of the metal waste through the magnet blocks 15 when protecting the outside of the grinding table 2 to achieve the collection effect.The bottom end of the limit block 14 is rotatably connected to a support block 16 through a turn pin, and the support block 16 is horizontally distributed at the bottom of the limit block 14. The support block 16 of this structure can be supported on both sides of the bottom of the magnet block 15 by rotating at the bottom of the limit block 14 to ensure the stability of the magnet block 15 installed between the limit blocks 14. A take-up drum 17 is provided inside the storage box 10, and the elastic rope 11 is wound around the outside of the take-up drum 17, and a wire harness block 18 is provided on one side of the inner wall of the bottom end of the storage box 10. A locking screw is inserted at the connection of the wire harness block 18. The elastic rope 11 of this structure can be retracted to a suitable length on the take-up drum 17 and locked by the wire harness block 18, thereby ensuring that the elastic rope 11 can achieve different degrees of stretching of the shield 4. The shield 4 is a rectangular structure as a whole, and the width of the shield 4 is greater than the width of the grinding table 2. The shield 4 of this structure can be smoothly enclosed outside the grinding table 2 to achieve the effect of protecting metal scraps.

[0017] Working principle: When using the grinding machine with a protective structure, first, the elastic rope 11 is retracted to a suitable length through the take-up drum 17 and locked with the harness block 18, and then the hook at the outer end of the elastic rope 11 is connected to the hanging ring on the outside of the sleeve 12. When the cylinder 6 is driven, it will drive the grinding mechanism 5 to move downward inside the frame 3. During the downward movement of the grinding mechanism 5, it will enter the inside of the protective cover 4 through the through-hole 8 until the mounting plate at the top of the grinding mechanism 5 drives the pressure ring 7 to embed into the recessed portion of the inner wall edge of the through-hole 8. At this time, the protective cover 4 will be linked by the grinding mechanism 5. When the protective cover 4 is linked, it will synchronously drive the sleeve 12 to slide downward on the outside of the vertical shaft 13, and the sleeve When 12 slides, it will also drive the elastic rope 11 to stretch until the shield 4 blocks the outside of the grinding table 2 at a suitable position to protect the metal waste generated during the processing. When the cylinder 6 drives the grinding mechanism 5 to rise for recovery, the shield 4 will move upward synchronously under the elastic force of the elastic rope 11, so that the staff can conveniently disassemble and assemble workpieces on the grinding table 2, and the staff can also install the magnet block 15 between each group of limit blocks 14, and then rotate the support block 16 to support the two sides of the bottom of the magnet block 15. In this way, when the shield 4 protects the outside of the grinding table 2, a part of the metal waste can be absorbed by the magnet block 15 for collection, thereby completing a series of work.
