Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing production, in particular to a precision grinding machine for mechanical processing. Background Art

[0002] A grinder is a special machine tool that uses various types of abrasive tools to perform grinding on the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and perform operations such as grinding, finishing, and polishing on the workpiece to achieve specific size, shape, and surface quality requirements. Of course, in addition to grinding wheels, some abrasive tools such as oilstones and abrasive belts can also be used for grinding. Different types of grinders include honing machines, superfinishing machines, belt grinders, grinders, and polishing machines. These grinders play an important role in various industrial fields. Their main purpose is to provide high precision for workpiece processing. The parts processed by the grinder will be more precise;

[0003] A mechanical precision grinding machine with a publication number of CN 220993996 U is retrieved, which can facilitate blowing of parts and grinding heads through a blowing mechanism, thereby reducing the difficulty of blowing of the outer surfaces of the parts and the grinding heads, thereby preventing dust and dirt from the outside from accumulating on the surfaces of the parts and the grinding heads, thereby ensuring the cleanliness of the outer surfaces of the parts and the grinding heads, and preventing the problem of dirt interfering with the grinding of parts;

[0004] The shortcomings of the precision grinder for mechanical processing in the above comparative example: the blowing structure of the device is only arranged at the top position of the driving motor. When the grinder is actually used for grinding work, the dust generated tends to spread widely around. It is obviously difficult to effectively maintain the parts box and the outer surface of the grinding head to keep them clean by relying solely on the blowing structure located at the top. In such a case, it is easy to cause dust to accumulate on the outer surface of the parts box and the grinding head, which will have a certain degree of adverse effect on the subsequent processing accuracy and processing quality, and may also make the working environment of the entire grinder become worse, and there is a certain potential threat to the health of the operator.

DETAILED DESCRIPTION

[0020] 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.

[0021] like Figures 1 to 6 As shown, the utility model provides a precision grinding machine for mechanical processing, comprising a machine tool frame 1, a dust collecting structure 2 mounted above and behind the machine tool frame 1, and a height adjustment structure 3 mounted on the back of the machine tool frame 1;

[0022] The dust collection structure 2 includes a dust collection hood 21 and a movable block 22 fixedly connected to the back of the dust collection hood 21, and extension plates 23 respectively installed on both sides of the movable block 22. The inner walls of the two extension plates 23 are provided with dust collection heads 24 and a dust collection box 25 is provided below the two extension plates 23. A fan 29 is installed inside the dust collection box 25. A guide head 26 is installed on the inner wall of the dust collection hood 21. The top of the guide head 26 is through-connected with an A transmission pipe 27. The back of the dust collection head 24 is through-connected with a B transmission pipe 28. The other ends of the A transmission pipe 27 and the B transmission pipe 28 extend to the interior of the dust collection box 25 and are through-connected with the output end of the fan 29.

[0023] The above scheme is adopted: through the design of the dust suction structure 2, during the implementation of the grinding operation, the cylinder 32 can apply a driving force to push the movable block 22, thereby driving the dust hood 21 and the servo motor 41 and the grinding head installed therein to achieve a synchronous downward movement. At the same time, the movable block 22 also drives the extension plates 23 located on both sides thereof to move downward. When the servo motor 41 is started to cause the grinding head to start rotating and then start the grinding operation, the fan 29 is started. In this way, the dust suction head 24 arranged on the top wall of the dust hood 21 can effectively absorb the dust and impurities around the grinding head. Not only that, the guide head 26 can also effectively gather and collect the dust in a diffuse state around the grinding head. Finally, the collected dust will be transmitted to the inside of the dust box 25, thereby realizing centralized collection and storage, thereby ensuring that the outer surface of the parts box and the grinding head can be maintained in a clean state.

[0024] like Figures 1 to 6 As shown, it also includes a grinding structure 4 assembled inside the dust hood 21 , and the grinding structure 4 includes a servo motor 41 fixed to the inner wall of the dust hood 21 and a grinding disc 42 fixedly connected to the output end of the servo motor 41 .

[0025] The above solution is adopted: the servo motor 41 provides power for the rotation of the grinding disc 42 .

[0026] like Figures 1 to 6 As shown, the height adjustment structure 3 includes a support plate 31 and a cylinder 32 mounted on the top of the support plate 31, the output end of the cylinder 32 extends to the inside of the support plate 31 and is fixedly connected to the top of the movable block 22, a slide groove is provided on one side of the support plate 31 close to the dust hood 21, and movable grooves are provided on both side surfaces of the support plate 31, the movable block 22 is slidably connected to the inner wall of the slide groove, and the extension plate 23 is slidably connected to the inner wall of the movable groove.

[0027] By adopting the above scheme: the cylinder 32 can drive the movable block 22 to move downward, and when the movable block 22 moves downward, it can drive the dust cover 21 and the servo motor 41 and the grinding disc 42 inside it to move downward, and the movable block 22 can drive the extension plate 23 to move synchronously, and the movable groove runs through both sides of the slide groove.

[0028] like Figures 1 to 6 As shown, the inner wall of the dust collection box 25 is provided with a collecting groove, and the outer wall of the collecting groove is hinged with a sealing door 251.

[0029] With the above solution, the sealing door 251 is in a normally closed state. When the machine stops grinding, the sealing door 251 needs to be opened to clean the dust and impurities inside the dust box 25.

[0030] The working principle and use process of this utility model:

[0031] First, the part to be polished needs to be accurately placed on the frame bed and ensure that it is in a specific position directly below the polishing head. Then, the cylinder 32 is started. At this time, the cylinder 32 generates a driving force to push the movable block 22 to move downward in the vertical direction. During the downward movement of the movable block 22, it can not only drive the extension plates 23 on both sides to move accordingly, but also drive the dust cover 21, the servo motor 41 and the polishing head to move downward together. Subsequently, the servo motor 41 and the fan 29 are started. When the servo motor 41 is started, Its rotational motion will drive the grinding head to start rotating, and the parts will be ground through the high-speed rotation of the grinding head. In this process, the dust head 24 on the top wall of the dust hood 21 can use its own functional characteristics to absorb the dust and impurities around the grinding head. Not only that, the guide head 26 can also play a key role, and can effectively gather and collect the dust diffused around the grinding head. Finally, the collected dust will be transmitted to the inside of the dust box 25 through the A transmission pipe 27 and the B transmission pipe 28.
