Detailed Description

In order to enable those skilled in the art to better understand the technical solution of the present utility model, the technical solution of the present utility model is further described below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 6, the safety cover 10 is mounted on a vertical grinder, the safety cover 10 is circumferentially wrapped around the outer periphery of a grinding wheel 20 of the vertical grinder, and a grinding opening 101 is formed in the peripheral surface of the safety cover 10 to allow the grinding wheel 20 to pass through. In general, when the vertical grinder is used, an operator holds an object to be ground (such as a cutting tool, shown as 40) in a state that the grinding wheel rotates at a high speed, and protrudes from the grinding opening 101 into contact with the surface of the grinding wheel 20 to perform a grinding operation.

In order to improve the operation safety of the conventional vertical grinder, an auxiliary shield 1 for controlling the opening size of the grinding opening 101 is provided to the safety shield 10. In operation, according to the specification size of the object to be ground, the auxiliary protection cover 1 is driven to open the grinding opening 101 slightly larger than the opening of the object to be ground, the object to be ground can be stretched into contact with the grinding wheel 20, in this state, during grinding, waste residues splashed by grinding can be effectively blocked through the auxiliary protection cover 1, meanwhile, the broken grinding wheel 20 can be fully and effectively blocked after the grinding wheel 20 is broken, and an operator can be effectively protected. Preferably, the auxiliary shield 1 can be a hard transparent plate, so that the grinding state can be observed in real time during grinding.

In particular, as shown in fig. 3 to 4, the auxiliary shield 1 is composed of a rotating plate 11 which is parallel to the safety shield 10 and hinged on the inner wall thereof, and an arc-shaped baffle 12 which is vertically disposed at the outer end of the rotating plate 11 and is located inside the safety shield 10. By driving the rotation plate 11 to rotate, the arc-shaped baffle 12 at the outer end gradually controls the opening size of the grinding opening 101 to adapt to the penetration of the objects to be ground of different specifications into contact with the grinding wheel 20.

Because the circumferential length of the arc baffle 12 is greater than that of the grinding opening 101, the opening size of the grinding opening 101 can be sufficiently controlled by the arc baffle 12, and the arc baffle can be suitable for grinding protection of objects with wider specifications, such as grinding of thin plate workpieces, and the opening size of the grinding opening 101 can be controlled by the arc baffle 12, so that the arc baffle can be sufficiently protected. When the grinder is not in use, the grinding opening 101 can be completely closed by the arc baffle 12 so as to improve the safety of the grinder body.

In order to facilitate the object to be ground being protected by the auxiliary shield 1, and also in a grinding position which is proper and convenient for the operator, as shown in fig. 5, the auxiliary shield 1 divides the rotary plate 11 and the arc-shaped baffle 12 into a single shield body 1a which rotates relatively along the center thereof. By opening the single cover bodies 1a on two sides relatively, the object to be ground can enter into contact with the grinding wheel 20 from the center position of the grinding opening 101 for grinding, the problem that the grinding opening 101 is opened by the auxiliary protective cover 1 with an integral structure from one side, and the object to be ground is positioned at the awkward position of the end part of the grinding opening 101 is avoided, and therefore the convenience of grinding operation is improved.

In order to achieve that after the grinding openings 101 have been opened by rotation of the symmetrical single cover bodies 1a to an opening size adapted to the object to be ground and that the opening size has been kept unchanged, as shown in fig. 5-6, on the outer wall of the safety shield 10 adjacent to the grinding openings 101, there are provided limit bolts 2 rotatably attached to the outer peripheral surface of each of the single cover bodies 1a. The limit bolts 2 are in close contact with the outer peripheral surface of the single cover body 1a, so that the stability of opening the grinding opening 101 is maintained, and the problem that the grinding operation is smoothly carried out due to free rotation of the single cover body 1a caused by vibration of the grinding wheel 20 rotating at a high speed is avoided.

Preferably, in order to facilitate the collection of the grinding residues, as shown in fig. 5, a grinding collecting pipe 3 (which is disposed along the tangential direction of the grinding wheel 20) penetrating the inside of the safety shield 10 is disposed at the bottom of the safety shield 10 and at the outer side of the rotation direction of the grinding wheel 20, and the grinding residues that splash along with the high-speed rotation of the grinding wheel 20 are guided and discharged through the grinding collecting pipe 3, and a collecting bag (not shown in the figure) may be disposed at the outer port of the collecting pipe 3 for collection.

The principle of the utility model is as follows: during grinding operation, according to the specification of an object to be ground, the single cover bodies 1a on two sides of the auxiliary protective cover 1 are driven to simultaneously rotate in a far away mode, the grinding opening 101 of the safety protective cover 10 is opened to be suitable for the opening size of the object to be ground, the limiting bolts 2 are used for limiting the outer peripheral surface of the single cover body 1a in a close fit mode, the stability of the opening of the grinding opening 101 is kept, and then the object to be ground can be stretched into the opening to be contacted with the grinding wheel 20 rotating at a high speed for grinding operation. During the grinding operation, the single cover bodies 1a on both sides effectively block grinding slag generated by grinding, and simultaneously prevent the grinding wheel 20 from flying out at high speed when broken, so that the safety of the grinding operation is improved.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model. The present utility model is subject to various changes and modifications without departing from the spirit and scope thereof, and such changes and modifications fall within the scope of the utility model as hereinafter claimed.
