Description

A safe grinder

technical field

The utility model relates to a grinder, in particular to a safety grinder.

Background technique

In the machinery industry, especially in machining centers, especially manual grinders, it is often necessary to use grinders to process workpieces with large allowances when processing parts. Because grinders use the high-speed rotation of the grinding wheel, friction occurs with the workpiece. The working principle is used to process workpieces, so when processing some workpieces with a large amount of processing, the grinding wheel will produce a large amount of sand, and when the workpiece is processed with a large amount of processing, a large amount of iron dust sparks will be generated. In the process, the grinding wheel rotates at a high speed, which causes the sand particles and iron dust sparks to rotate together with the grinding wheel and are thrown out from the tangential direction of the upper end of the grinding wheel. Personal injury, even sand particles splashing into the eyes may cause blindness and so on.

China patent authorization announcement number: CN202174473, the date of authorization announcement is March 28, 2012, which discloses a grinder, including a base, a pillar, a grinder switch, a desktop grinder, a rubber cushion, the pillar is installed on the base, and the grinder The switch is located on the base, the column is connected with the desktop grinder, and there is a rubber cushion layer at the connection between the desktop grinder and the column. The grinder with this structure greatly improves the firm performance of the base, makes the base of the grinder difficult to break during the vibration process, and greatly improves the anti-vibration performance of the grinder. Its disadvantage is that when this kind of grinder is used, especially when processing workpieces with large allowances, sand grains and iron dust sparks will splash out from the tangential direction of the upper end of the grinding wheel, which is easy to cause personal injury to the operator , is not safe to use.

Utility model content

In order to overcome the shortage that sand grains and iron dust sparks are easy to splash out and cause personal injury to the operator when the grinder in the prior art is used, the utility model provides a machine that can effectively prevent sand grains and iron dust sparks from splashing out, and is more convenient to use. Safety, safety type grinder that protects the user from injury.

In order to achieve the above object, the utility model adopts the following technical solutions:

A safety type grinder, comprising a grinder body, a grinding wheel is arranged in the grinder body, a grinding wheel cover is arranged on the grinding wheel, the grinding wheel cover is fixedly connected with the grinder body, and the grinding wheel cover on the upper end of the grinding wheel A safety baffle is provided on the top, a U-shaped opening is provided at the lower end of the safety baffle, and a connecting block is provided at the upper end of the safety baffle, and the connecting block is connected with the grinding wheel cover. When the workpiece is processed, the workpiece is ground close to the grinding wheel, and the sand grains and iron dust sparks rotate along the grinding wheel, and finally splash out from the gap between the upper end of the grinding wheel and the grinding wheel cover. A safety baffle is installed at the exit. The three sides of the U-shaped opening at the lower end of the safety baffle are respectively stuck on the two sides of the grinding wheel and a circular edge. The sparks of sand and iron dust are blocked by the safety baffle and will not splash out. Therefore, the user is protected from injury, and the use of the grinder is safer and more reliable.

Preferably, the section of the connecting block is L-shaped, the vertical side of the connecting block is attached to the safety baffle, and the bottom surface of the connecting block is bolted to the grinding wheel cover. The connecting block connects the safety baffle and the grinding wheel cover for easy disassembly and replacement.

Preferably, the upper end of the safety baffle is provided with a vertical slotted hole, and an adjusting bolt is arranged in the slotted hole, and the safety baffle is connected with the connecting block through the adjusting bolt. The safety baffle can be moved up and down along the long slot hole to adjust the gap between the bottom of the U-shaped opening and the arc surface of the grinding wheel. It is also suitable for grinding wheels with different radii, and has strong versatility.

Therefore, the utility model has the beneficial effects of effectively preventing sand grains and iron dust sparks from splashing out, making it safer to use and protecting users from harm.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

A safety type grinder as shown in Figure 1 and Figure 2, includes a grinder body, a grinding wheel 1 is arranged in the grinder body, a grinding wheel cover 2 is arranged on the grinding wheel 1, and the grinding wheel cover 2 is fixedly connected to the grinder body , the grinding wheel cover 2 at the upper end of the grinding wheel 1 is provided with a safety baffle 3, and the lower end of the safety baffle 3 is provided with a U-shaped opening 4, the two sides of the U-shaped opening are correspondingly stuck on the two sides of the grinding wheel, and the bottom of the U-shaped opening Close to the arc edge of the grinding wheel, the upper end of the safety baffle 3 is provided with a connection block 5, the cross section of the connection block 5 is L-shaped, the vertical side of the connection block 5 is fitted and connected with the safety baffle 3, and the bottom surface of the connection block 5 is connected to the safety baffle 3. The grinding wheel cover is connected by 2 bolts, and the removal, installation and replacement of the protective baffle are very convenient. When the operator grinds the workpiece on the grinding wheel, the sand grains generated by the grinding wheel and the iron dust sparks generated by the workpiece will rotate along the grinding wheel, and finally pass through the grinding wheel. The gap with the opening of the grinding wheel cover is blocked by the safety baffle, so as to prevent sand particles and iron dust sparks from splashing out and causing injury to the operator; the upper end of the safety baffle 3 is provided with a vertical slot 6 , the long slot hole 6 is provided with an adjusting bolt 7, the safety baffle 3 is connected with the connecting block 5 through the adjusting bolt 7, the safety baffle can slide up and down along the long slot hole, thereby adjusting the gap between the bottom of the U-shaped opening and the circumferential surface of the grinding wheel gap, so that the same safety baffle can be used on different types of grinding machines, which is very versatile. Therefore, the utility model has the beneficial effects of effectively preventing sand grains and iron dust sparks from splashing out, making it safer to use and protecting users from harm.
