[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 A low-noise steel structure grinding and polishing machine includes: an angle grinder body 1, a power interface 2, a control switch 3 and a grinding blade 6, and the control switch 3 and the power interface 2 are assembled on the outside of the angle grinder body 1, and the grinding blade 6 is connected to the output end of the angle grinder body 1, the outside of the angle grinder body 1 is connected to a handle 4, the inner bottom of the handle 4 is connected to an airbag 41, and the bottom of the angle grinder body 1 is equipped with a noise reduction mechanism 5.
[0024] The angle grinder body 1, power interface 2, control switch 3 and grinding blade 6 are combined to form a common angle grinder equipment in the prior art. The power interface 2 can supply power to the angle grinder body 1, the control switch 3 can control the start of the angle grinder body 1, and the grinding blade 6 can polish and grind steel structures.
[0025] The handle 4 facilitates the worker to drive the angle grinder body 1 , and the airbag 41 can confine the worker's palm inside the handle 4 by squeezing, thereby improving the contact between the worker's palm and the handle 4 .
[0026] Please refer to Figure 3 and Figure 4 The noise reduction mechanism 5 includes a hollow cylinder 51. The outside of the hollow cylinder 51 is connected to a hose 57, and the hose 57 is connected to the airbag 41. The inside of the hollow cylinder 51 is slidably connected to a piston 54. The bottom of the piston 54 is connected to a ring plate 55. The bottom of the ring plate 55 is connected to a rubber plate 56. The inner side of the hollow cylinder 51 is equipped with a sound-absorbing panel 53. The sound-absorbing panel 53 is a common sound-absorbing material in the prior art.
[0027] The hollow cylinder 51 allows the piston 54 to move inside it to generate airflow. The ring plate 55 facilitates the rubber plate 56 to drive the piston 54 to move. The rubber plate 56 is elastic. When the grinding blade 6 is tilted for grinding, the entire rubber plate 56 fits the steel structure.
[0028] An observation window 52 is embedded in the top of the hollow cylinder 51, and the observation window 52 is a ring-shaped transparent plate. The observation window 52 makes it convenient for staff to observe the grinding and polishing effect inside the hollow cylinder 51. The top of the piston 54 is equipped with a spring 58, and the spring 58 is connected to the inner top of the hollow cylinder 51. The spring 58 can drive the ring plate 55 to return after movement. The ring plate 55 includes an annular plate, and the inner side of the annular plate is equipped with a honeycomb plate through Velcro. The Velcro and the honeycomb plate can absorb and reduce the noise generated by the grinding blade 6.
[0029] The hollow cylinder 51 is sleeved on the outside of the angle grinder body 1, and bolts are assembled between the hollow cylinder 51 and the angle grinder body 1. The bolts can facilitate the disassembly and maintenance of the hollow cylinder 51. The outside of the handle 4 is wrapped with an anti-slip cover, and the handle 4 is connected to the angle grinder body 1 through bolts. The anti-slip cover prevents the handle 4 from slipping out of the hands of the staff during use.
[0030] In this solution, the power interface 2 is first connected to the external power cord, and the angle grinder body 1 and the handle 4 are held with both hands to press the grinding blade 6 against the outside of the steel structure to be ground. At this time, the ring plate 55 and the rubber plate 56 are driven by the spring 58 to fit tightly against the outside of the steel structure. At the same time, the piston 54 moves inside the hollow cylinder 51, and the air flow is discharged into the inside of the airbag 41 through the hose 57, so that the airbag 41 expands, thereby protecting the worker's palm inside the handle 4 and improving the worker's overall control over the angle grinder body 1. When the control switch 3 is pressed to control the noise reduction mechanism 5 to rotate, the outside of the steel structure is ground. At this time, the noise generated by the grinding is absorbed and reduced by the ring plate 55 and the sound absorbing plate 53. The worker can observe the grinding condition of the grinding blade 6 through the observation window 52, thereby completing the grinding operation of the steel structure.
[0031] When the steel structure is being ground, the noise generated by the grinding is absorbed and reduced by the added noise reduction mechanism 5, and the waste chips generated by the grinding are blocked at the same time. When the noise reduction mechanism 5 is driven, the airbag 41 is driven to move, and then the worker's arm is protected to the inside of the handle 4, thereby improving the worker's control over the entire angle grinder body 1, and preventing the angle grinder body 1 from slipping out of the hand during use and causing damage to the angle grinder body 1 and the worker.
