Description

Technical Field

[0001] The invention relates to the field of metal surface processing, in particular to a metal surface grinding machine. Background Art

[0002] Metal materials refer to metal elements or materials with metal properties that are mainly composed of metal elements, including pure metals, alloys, metal material intermetallic compounds and special metal materials. Most mechanical materials are metal materials. During the processing of metal materials, the surface of the metal materials needs to be polished, which has the function of removing rust and facilitating subsequent processing. Existing grinders, such as the utility model patent with publication number CN219255062U, disclose a metal surface grinder, including a fixed base plate and an extrusion positioning mechanism, a fixed seat, a lifting rod, a connecting plate, a fixed plate and a grinding mechanism arranged on one side of the fixed base plate, wherein one side of the top of the fixed base plate is fixedly connected to the fixed seat, and the lifting rod is slidably connected inside the fixed seat. In order to ensure the stability of metal parts during grinding, the metal parts are placed in a placement frame with the side to be grinded facing upward, and then the rotating rods on the left and right sides of the placement frame are rotated. The rotating rod drives the third threaded rod fixed thereto to move toward the inside of the placement frame, and the other side of the third threaded rod squeezes the positioning plate abutting therewith. The positioning plate is subjected to force and drives the fixed rod fixed thereto to slide in the placement frame. The positioning plate simultaneously stretches the spring fixed thereto, which is convenient for resetting the positioning plate after grinding. As the positioning rods approach each other, the parts to be grinded are squeezed and fixed, thereby ensuring the stability of the parts to be grinded during grinding. During the grinding process, the grinding debris will fall onto the platform and the metal surface, which makes subsequent cleaning more troublesome. In addition, only straight-line single-sided grinding is possible. After completing single-sided grinding, it is necessary to remove and reinstall it before grinding the other side again, and the grinding efficiency is low. Summary of the invention

The grinding mechanism includes a mounting plate 11 arranged in the processing chamber 2, and the upper end of the mounting plate 11 is fixedly connected to a plurality of electric telescopic rods 12, and the telescopic ends of the plurality of electric telescopic rods 12 are commonly fixedly connected to a belt sander 13. The belt sander 13 is a prior art. When it is used, the sanding belt is in a rotating state for grinding. A first slide groove 8 is opened on the inner wall of the rear side of the processing chamber 2, and a rotating threaded rod 9 is rotatably connected between the inner walls on the left and right sides of the first slide groove 8. A first slider 10 is threadedly connected to the rotating threaded rod 9. The first slider 10 is slidably connected to the inner wall of the first slide groove 8, and the front side of the first slider 10 passes through the notch of the first slide groove 8 and is fixedly connected to the lower end of the mounting plate 11; As an embodiment of the present invention, it also includes a noise reduction mechanism, which is used to reduce the noise generated during grinding. The noise reduction mechanism includes a piston cylinder 25 fixedly connected to the left side of the shell 1, a piston plate 16 that can slide up and down is arranged in the piston cylinder 25, the left end of the rotating threaded rod 9 extends to the outside and is fixedly connected to the rotating disk 14, the left eccentric part of the rotating disk 14 is rotatably connected to the connecting rod 15, the other end of the connecting rod 15 is rotatably connected to the lower end of the rotating disk 14, a hollow ring 22 is fixedly connected to the inner wall of the processing chamber 2, a plurality of atomizing nozzles 26 are installed on the inner side of the hollow ring 22, the inner top space of the piston cylinder 25 is connected to the inner bottom space of the water storage tank 3 through the first one-way tube 23, the inner top space of the piston cylinder 25 is connected to the inside of the hollow ring 22 through the second one-way tube 24, and one-way valves are installed inside the first one-way tube 23 and the second one-way tube 24; As an embodiment of the present invention, in order to further facilitate the separation of water and debris, a collecting box 6 is fixedly connected to the right side of the shell 1, the right side space of the water storage tank 3 is connected to the internal space of the collecting box 6 through a liquid drop port 5, an inclined separation net 4 is fixedly connected to the inner wall of the water storage tank 3, a first sealing door 30 is installed on the front side of the shell 1, and a second sealing door 31 is installed on the front side of the collecting box 6.

[0022] In the present invention, when in use, the first sealing door 30 is opened, and then the rectangular metal piece is placed between the two limit plates 28, and the second motor 17 is started to move. After the second motor 17 rotates, it will drive the bidirectional threaded rod 20 to rotate, and the rotation of the bidirectional threaded rod 20 will drive the two second sliders 21 to move relative to each other, so that the two vertical plates 27 move relative to each other, and the limit plates 28 move relative to each other to clamp and limit the workpiece; Subsequently, the first sealing door 30 is closed, and the first motor 7 is started.

It should be noted that the grinding process is carried out in a sealed environment, which effectively reduces the propagation of noise. In addition, the rotation of the first motor 7 will also rotate the rotating disk 14. The connecting rod 15 can be used to allow the piston plate 16 to reciprocate up and down. The up and down movement of the piston plate 16, in conjunction with the first one-way tube 23 and the second one-way tube 24, can achieve the purpose of pumping the water inside the water storage tank 3 into the piston cylinder 25, and finally press it into the hollow ring 22 from the second one-way tube 24, and spray it from multiple atomizing nozzles 26, so that there are more atomized water droplets in the processing chamber 2. The small water droplets in the water mist can scatter and absorb sound waves, which will weaken the propagation energy of the sound waves to a certain extent. Especially in high-frequency sound waves, because the sound waves are short, the air must move back and forth quickly to propagate high-frequency sounds, and the small water droplets in the mist will reflect and refract these sound waves many times, thereby losing part of the energy, while suppressing the propagation of sound and suppressing noise.
