[0019] (1) When the low-dust grinder for building construction is used for grinding, the workpiece is placed on the work plate, and the motor is started. The motor drives the threaded rod to rotate.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1: The extrusion rod 12 is provided to quickly clamp the workpiece, and the nozzle 24 is used to achieve dust reduction during the grinding process. Figure 1-Figure 4 As shown:

[0033] It includes a working plate 1, a bracket is fixedly connected to the lower surface of the working plate 1, a vertical plate 4 is bolted to the upper surface of the working plate 1, a lower connecting plate 2 is fixedly connected to the lower surface of the working plate 1, a grinding disc 5 is connected to the surface of the vertical plate 4 through an electric slide rail, a motor 3 is bolted to the surface of the lower connecting plate 2, and a threaded rod 7 is fixedly connected to the output end of the motor 3;

[0034] A limiting groove 6 is provided on the surface of the working plate 1 , and an upper connecting block 9 is slidably arranged inside the limiting groove 6 , and a long rod 11 is fixedly connected to the surface of the upper connecting block 9 , and an extrusion rod 12 is fixedly connected to the surface of the long rod 11 .

[0035] The upper surface of the working plate 1 is fixedly connected to the vertical plate 13, and the surface of the vertical plate 13 is rotatably provided with a nozzle 24, and the upper surface of the working plate 1 is fixedly connected to the water tank 10, the surface of the threaded rod 7 is threadedly connected to the movable plate 8, and the movable plate 8 is symmetrically distributed about the center of the threaded rod 7, and the threads on the left and right sides of the threaded rod 7 have opposite rotation directions.

[0036] When performing the grinding work, the workpiece is placed on the working plate 1, and the motor 3 on the surface of the lower connecting plate 2 is started. The motor 3 drives the threaded rod 7 to rotate. At this time, the threaded rod 7 drives the long rod 11 and the extrusion rod 12 to move through the movable plate 8, the limit groove 6 and the upper connecting block 9. Finally, the extrusion rods 12 on the left and right sides clamp and fix the workpiece. The operation process is quick and convenient. When grinding, the grinding operation of the workpiece is realized by the grinding disc 5. At the same time, when the grinding work is in progress, the nozzle 24 works. At this time, the nozzle 24 sprays water mist, which plays a role in dust reduction and temperature reduction, which is convenient for the normal progress of the grinding work.

[0037] Embodiment 2: Different from Embodiment 1, the push rod 21 is provided so that the nozzle 24 can be in a swinging state when working, thereby expanding the working range of the nozzle 24. Figure 5-Figure 6 As shown:

[0038] The upper surface of the movable plate 8 is fixedly connected to the upper connecting block 9, the extrusion rods 12 are evenly distributed on the surface of the long rod 11, the surface of the long rod 11 is fixedly connected to the rack 14, the surface of the vertical plate 13 is fixedly connected to the outer plate 15, and the inner part of the outer plate 15 is rotatably provided with a connecting shaft 16, and the end of the connecting shaft 16 is fixedly connected to a gear 17.

[0039] The gears 17 are symmetrically distributed about the center of the connecting shaft 16, and the gears 17 correspond one to one with the racks 14. The surface of the vertical plate 13 is fixedly connected to the limit rod 19, the surface of the connecting shaft 16 is fixedly connected to the cam 18, and the surface of the cam 18 is fitted with a force plate 20, and the force plate 20 is slidably connected to the limit rod 19, and the upper surface of the force plate 20 is fixedly connected to the push rod 21.

[0040] The limit rod 19 is an inverted "U" shape when viewed from the front, and a guide rod 22 is fixedly connected to the surface of the vertical plate 13, and a pipe sleeve 23 is fixedly connected to the surface of the guide rod 22, and the guide rod 22 is an inverted "U" shape when viewed from the top, and a nozzle 24 is fixedly connected to the surface of the pipe sleeve 23, and the nozzles 24 are evenly spaced on the surface of the pipe sleeve 23, and the nozzles 24 are connected to the water tank 10 through an external hose, and a positioning rod 25 is fixedly connected to the surface of the vertical plate 13.

[0041] During the movement of the long rod 11, the rack 14 will be driven to move synchronously. When the rack 14 moves, the connecting shaft 16 will be driven to rotate inside the outer plate 15 through the gear 17. When the connecting shaft 16 rotates, the cam 18 will be driven to rotate synchronously, and then the cam 18 will intermittently push the force-bearing plate 20. When the force-bearing plate 20 is pushed, the force-bearing plate 20 rises, and when the force-bearing plate 20 is not pushed, the force-bearing plate 20 falls under the action of its own gravity. The above process is repeated, and the force-bearing plate 20 is moved by the thrust and its own gravity. Under the action of the limit rod 19, it makes reciprocating linear motion in the vertical direction, and then the force plate 20 intermittently pushes the pipe sleeve 23 through the push rod 21. At this time, the pipe sleeve 23 and the nozzle 24 swing around the guide rod 22 under the action of thrust and their own gravity. At this time, the working range of the nozzle 24 is increased, and the dust reduction and cooling effects are better. The positioning rod 25 plays a role in limiting the rotation angle of the pipe sleeve 23, so that the pipe sleeve 23 will not rotate excessively, thereby ensuring the stability of the working of the pipe sleeve 23 and the nozzle 24.

[0042] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
