[0002] A grinding wheel machine is a common piece of equipment used to sharpen various cutting tools and other tools. It is also used for grinding, deburring, and cleaning small parts. It mainly consists of a base, a grinding wheel, an electric motor or other power source, a bracket, a protective cover, and a water supply device.

[0003] Existing ordinary grinding machines do not have a dust collection function, and generate a lot of dust during operation, making the working environment very harsh and affecting the physical and mental health of workers. In addition, a lot of dust can also affect the worker's vision, which not only affects operation but also has an impact on health. At the same time, grinding machines are generally used by hand to grind the workpiece. When the workpiece is held by hand, it is easy for it to slip, thereby reducing the grinding accuracy.

In use, the workpiece to be ground is placed on the limiting block 13, so that the grinding end of the workpiece is outside the limiting block 13. The clamping block 14 is installed on the limiting block 13 so that the clamping block 14 clamps and fixes the workpiece. After the workpiece is clamped, the limiting block 13 is slid to make the limiting block 13 drive the workpiece and the clamping block 14 to move synchronously, so that the workpiece is close to the grinding wheel of the grinding machine 2, thereby realizing the grinding of the workpiece.

In use, by tightening the bolt 19, the bolt 19 drives the clamping block 14 to move downward, thereby fixing the workpiece between the limiting block 13 and the clamping block 14. At the same time, by loosening the bolt 19, the limiting block 13 and the clamping block 14 are separated, and the workpiece can be taken out, which facilitates the replacement of the workpiece and improves the grinding accuracy of the workpiece.

The limiting groove 20 of this utility model can facilitate the limiting of workpieces in the same batch.

[0072] Example 9.

[0073] like Figure 1-9 As shown, the present invention provides a grinding wheel machine 2 with a dust removal device, including a workbench 1, a grinding wheel machine 2 disposed on the workbench 1, protective covers 3 disposed at both ends of the grinding wheel machine 2, a dust collection mechanism disposed at the bottom of the workbench 1 and connected to the two protective covers 3, and a dust collection mechanism disposed inside the workbench 1 and connected to the dust collection mechanism for collecting grinding debris; the workbench 1 is provided with a clamping mechanism for clamping workpieces.

During disassembly, simply rotate the bolt 19 in the opposite direction to separate the clamping block 14 and the limiting block 13, and the workpiece can be taken out, thus facilitating the clamping of the workpiece.

[0078] Example 10.

[0079] like Figure 1-9 As shown, the present invention provides a grinding wheel machine 2 with a dust removal device, including a workbench 1, a grinding wheel machine 2 disposed on the workbench 1, protective covers 3 disposed at both ends of the grinding wheel machine 2, a dust collection mechanism disposed at the bottom of the workbench 1 and connected to the two protective covers 3, and a dust collection mechanism disposed inside the workbench 1 and connected to the dust collection mechanism for collecting grinding debris; the workbench 1 is provided with a clamping mechanism for clamping workpieces.

The protective plate 25 can prevent grinding debris from splashing onto the operator's face during the grinding process.

[0082] Working principle

[0083] In use, the workpiece is placed between the limiting block 13 and the clamping block 14, with the grinding end of the workpiece located outside the limiting block 13. The workpiece is fixed between the limiting block 13 and the clamping block 14 by manually tightening the bolt 19. The grinding wheel 2 and the blower 7 are started, and the limiting block 13 is manually pushed to move. The limiting block 13 drives the clamping block 14 and the workpiece to move synchronously, so that the workpiece comes into contact with the grinding wheel of the grinding wheel 2, thereby grinding the workpiece. At the same time, the debris generated during the workpiece grinding process falls into the dust collection hood 5 under the obstruction of the protective cover 3. Since the dust collection pipe 6 is in a negative pressure state under the action of the blower 7, the debris in the dust collection hood 5 enters the dust collection bag 9 through the dust collection pipe 6 under the action of negative pressure. The dust collection bag 9 filters and intercepts the debris, thereby preventing the grinding debris from being scattered in the air. After grinding is completed, the workpiece can be removed from between the limiting block 13 and the clamping block 14 by manually loosening the bolt 19, thus facilitating the grinding of the workpiece.

[0084] The grinding wheel 2, fan 7, and dust collection bag 9 used in this utility model are all existing technologies and can be purchased and used directly on the market. Therefore, the structure, principle, and circuit of the grinding wheel 2, fan 7, and dust collection bag 9 will not be described in detail here.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
