Moreover, during the operation of traditional polishing devices, the rotational friction of each component is large, resulting in poor stability and smoothness of the device operation, and even aggravating the damage to the polishing equipment.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The surface polishing device of this electromechanical equipment features a dust removal mechanism designed to effectively absorb dust during the polishing process through the cooperation of a fan and a dust collection hood. The rubber ring enhances the seal between the dust collection hood and the equipment surface, reducing dust spillage. The spring allows the dust collection hood to adapt to different surface shapes, ensuring dust removal efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Based on existing technology, traditional handheld polishing machines generate dust during the polishing process. This dust flies everywhere, severely polluting the working environment and easily being inhaled by operators, posing a health hazard. Furthermore, dust accumulation can lead to equipment malfunctions, increasing maintenance costs and cleaning difficulty. Therefore, this device is equipped with a dust removal mechanism. Please refer to [link / reference]. Figures 1-3 This utility model provides a technical solution: a surface polishing device for electromechanical equipment, including a polishing machine body 1, an anti-slip rubber sleeve 2 fixedly installed on the polishing machine body 1, a power cord 3 at the tail of the polishing machine body 1 connected to the main board inside the polishing machine body 1, a polishing head 4 fixedly installed at the front end of the polishing machine body 1, a handle 5 threadedly installed on the side of the polishing head 4, a dust collection hood 6 movably installed below the polishing head 4, and a duct 7 on the side of the dust collection hood 6 for connecting to a fan; the surface polishing device for electromechanical equipment includes a dust removal mechanism and a buffer mechanism, the dust removal mechanism includes the polishing head 4, a buffer groove 201 at the lower end of the polishing head 4, a dust collection hood 6 movably installed in the buffer groove 201, and a limiting edge 202 at the upper edge of the dust collection hood 6, the thickness of the limiting edge 202 being less than the width of the buffer groove 201.

[0024] Four sets of springs 203 are fixedly installed between the polishing head 4 and the dust collection hood 6. Multiple sets of slots 204 are provided at the lower edge of the dust collection hood 6. An arc-shaped mounting shaft 205 is fixedly installed in the slot 204, and a rubber ring 206 is movably installed on the mounting shaft 205.

[0025] After the motor 303 starts, it drives the bevel gear 306 to rotate through the drive shaft 304. The bevel gear 306 meshes with the bevel gear 308, transmitting power to the transmission shaft 309. The transmission shaft 309 drives the driven shaft 313 to rotate through the limiting groove 311 and the limiting block 312, ultimately causing the polishing wheel 8 to rotate at high speed for polishing. The fan is connected to the dust collection hood 6 through the air duct 7, forming a negative pressure adsorption system. When the polishing wheel 8 polishes the surface of the equipment, the generated dust is sucked into the dust collection hood 6 and discharged to the external dust collection equipment through the air duct 7. The dust collection hood 6 is connected to the buffer groove 201 of the polishing head 4 through the spring 203, and can float up and down. When it comes into contact with the uneven surface of the equipment, the spring 203 is compressed or extended, so that the dust collection hood 6 fits tightly against the surface of the equipment.

[0026] Example 2:

[0027] Based on Example 1, during polishing, if the equipment surface is uneven, the polishing wheel may generate significant impact force with the equipment. This not only accelerates the wear of the polishing wheel and shortens its service life, but also easily scratches and dents the equipment surface, affecting workpiece quality and increasing the scrap rate. Furthermore, traditional polishing devices experience significant rotational friction between components during operation, leading to poor stability and smoothness of operation, and even exacerbating damage to the polishing equipment. Therefore, this device is equipped with a buffer mechanism. Please refer to [link / reference]. Figures 4-5 This utility model provides a technical solution: a surface polishing device for electromechanical equipment, the buffer mechanism includes a polishing machine body 1 and a polishing head 4, the polishing machine body 1 is provided with a motor mounting groove 301, a motor 303 is fixedly installed in the motor mounting groove 301, and multiple sets of ventilation grooves 302 are provided on the external polishing machine body 1.

[0028] The polishing head 4 has a cavity 305. The output shaft of the motor 303 is fixedly mounted on the drive shaft 304. The drive shaft 304 passes through the polishing head 4 and its end is fixedly mounted with a bevel gear 306 by a pin 307.

[0029] A second bevel gear 308 is movably installed inside the cavity 305. A first bevel gear 306 meshes with the second bevel gear 308. A drive shaft 309 is fixedly installed at the middle position of the second bevel gear 308. The drive shaft 309 is hollow inside. A fixing rod 310 is fixedly installed inside the polishing head 4. The fixing rod 310 is movably installed inside the drive shaft 309. A limiting groove 311 is provided inside the drive shaft 309. A driven shaft 313 is movably installed inside the drive shaft 309. A limiting block 312 is fixedly installed on the driven shaft 313. The limiting block 312 is movably installed in the limiting groove 311.

[0030] The drive shaft 309 has a ball groove 314 at the contact position with the polishing head 4, which contains multiple sets of balls 315. The bevel gear 308 has a ball groove 316 at the contact position with the polishing head 4, which contains multiple sets of balls 317. The lower end of the polishing head 4 has a rotating groove 318. An auxiliary rotating disk 319 is movably installed in the rotating groove 318. A limiting edge 320 is fixedly installed on the side of the auxiliary rotating disk 319. The upper and lower sides of the limiting edge 320 at the contact positions with the polishing head 4 have ball grooves 321, which contain multiple sets of balls 322. The driven shaft 313 floats up and down in the auxiliary rotating disk 319.

[0031] An auxiliary clamping plate 12 is fixedly installed on the driven shaft 313. The part of the driven shaft 313 that passes through the auxiliary clamping plate 12 is provided with a mounting stud 9. A clamping nut 11 is movably installed on the mounting stud 9 by means of threads. A polishing wheel 8 is placed between the auxiliary clamping plate 12 and the clamping nut 11. A trapezoidal mounting groove 10 is provided in the middle position of the polishing wheel 8. A spring 323 is fixedly installed between the auxiliary rotating disk 319 and the auxiliary clamping plate 12.

[0032] When the polishing wheel 8 encounters a protrusion or depression on the workpiece surface, it will be subjected to an upward or downward impact force. At this time, the driven shaft 313 floats up and down within the auxiliary rotating disk 319, compressing or stretching the second spring 323, converting the impact force into the elastic potential energy of the spring, thereby reducing damage to the polishing wheel 8 and the equipment. At the same time, the ball bearings inside the polishing machine reduce friction between components, improving operational stability and smoothness while extending the service life of the equipment.
