Description

Technical Field

[0001] The utility model belongs to the technical field of grinding machines, and in particular relates to a grinding machine for grinding metal castings. Background Art

[0002] The current grinding machines on the market will generate a large amount of dust and fine particles during the continuous friction between the material and the grinding wheel. As the grinding machine rotates at high speed, the dust and fine particles gradually diffuse into the nearby air, thereby polluting the surrounding environment. The workers are exposed to this environment for a long time, which is very likely to have an impact on their bodies. At the same time, in order to ensure the normal progress of grinding, after grinding for a period of time, it is necessary to remove the outer shells on both sides and clean the attachments on the surface of the grinding wheel, which undoubtedly reduces the efficiency of grinding. Therefore, a grinding machine for grinding metal castings is designed to solve the problem that the current grinding machine will cause a large number of fine particles to be generated in the surrounding air during operation, and cannot be ground for a long time and needs regular cleaning. Utility Model Content

[0021] See also Figure 1-Figure 3 As shown, as shown Figure 1 The left side of the middle shell 6 is the front end face, and the right side is the rear end face. The utility model provides the following technical solutions: a grinding wheel machine for grinding metal castings includes a shell 6 and a connecting pipe 4, a grinding wheel is rotatably arranged inside the shell 6, and a connecting hole 2 is opened in the middle of the rear end face of the shell 6, a connecting pipe 4 is fixed on the outer wall of the shell 6 and located outside the connecting hole 2, the end of the connecting pipe 4 is connected to the air pump, and the connecting pipe 4 is used to change the flow direction of the gas inside the shell 6, an engaging groove 13 is opened in the middle of the surface of the connecting pipe 4, an engaging plate 8 is engaged with the engaging groove 13, the engaging plate 8 is an arc-shaped plate, and an annular plate 11 is installed on one side of the inner wall of the engaging plate 8, the bottom of the annular plate 11 is in contact with the inner wall of the connecting pipe 4, and a filter screen 12 is arranged on the inner wall of the annular plate 11, auxiliary plates 7 are symmetrically installed on both sides of the outer wall of the engaging plate 8, and sub-buttons 9 are symmetrically installed on the end faces of both sides of the engaging plate 8, and female buckles 10 are symmetrically installed on both sides of the inner wall of the engaging groove 13, and the female buckle 10 is engaged with the sub-button 9.

[0022] Through the above technical solution: when in use, the air inside the shell 6 is pumped out to the rear of the shell 6 through the connecting pipe 4 by the air pump, so as to change the diffusion direction of fine particles, and use the filter screen 12 on the mosaic plate 8 to block fine particles, thereby reducing the problem of dust and fine particles affecting the normal operation of the air pump. After running for a long time, the two sides of the mosaic plate 8 can be clamped by the auxiliary plate and pulled upward to force the sub-buckle 9 to disengage from the mother buckle 10, so that the filter plate can be taken out and cleaned to ensure that the gas can circulate normally in the connecting pipe 4. Then, it is only necessary to put the mosaic plate 8 back into the mosaic groove 13 to force the sub-buckle 9 and the mother buckle 10 to be re-engaged and connected. The mosaic connection of the sub-buckle 9 and the mother buckle 10 is used to complete the fixed installation of the mosaic plate 8, so as to solve the problem that a large number of fine particles are generated in the surrounding air during the operation of the current grinding wheel machine.

[0023] See also Figure 1 and Figure 3 As shown, a cylinder 14 is installed on one side of the outer wall of the annular plate 11 and away from the air pump, and a guide ring 3 is installed inside the cylinder 14 and away from the filter screen 12. The inner wall of the guide ring 3 is inclined, and both ends of the cylinder 14 are located inside the engaging plate 8. The inner diameter of the guide ring 3 is smaller than the diameter of the filter screen 12. Velcro 5 is symmetrically installed on the upper and lower sides of the inner wall of the outer shell 6, and a brush strip 1 is attached to the Velcro 5, and the end of the brush strip 1 is in contact with the outer wall of the grinding wheel.

[0024] Through the above technical scheme: during the rotation of the grinding wheel, the continuous friction between the brush strip 1 and the surface of the grinding wheel is utilized to achieve the effect of automatically cleaning the attachments, and the fallen attachments can be synchronously moved with the airflow to the connecting pipe 4 for collection, and when the fine particles and attachments enter the connecting pipe 4, they are guided by the guide ring 3 to slide into the cylinder 14, and the fine particles and attachments are finally contacted with the filter screen 12 inside the annular plate 11, and the fine particles and attachments are blocked on the filter screen, and when the air pump is turned off, the dust and attachments fall downward under the action of gravity and are finally accumulated in the cylinder 14, and are blocked by the guide ring 3, so that most of them are located between the guide ring 3 and the filter plate, thereby facilitating the subsequent disassembly of the mosaic plate 8 and cleaning of the cylinder 14, and in addition, because the brush strip 1 and the outer shell 6 are adhered by the Velcro 5, when the outer shell 6 is opened to replace the grinding wheel, the brush strip 1 can be simultaneously torn off and replaced, so that the end of the brush strip 1 continues to maintain direct contact with the grinding wheel to increase the cleaning effect.
