Problems solved by technology

This operation is very troublesome, and after the dust collection cover is often disassembled and assembled, when the grinder is working, the dust collection cover is prone to abnormal noise, and the noise has a huge impact on the comfort of the working environment and the health of the staff. ;Furthermore, the dust collection hood is often disassembled and assembled, and it is inevitable that errors will occur during the operation process, which will affect the shape of the dust collection hood, and it may also make the dust collection hood and the grinder no longer match.

Embodiment 1

[0023] Such as figure 1 , figure 2 The grinder dust collection hood shown includes a base body 1 and a cover body assembly 2, wherein the cover body assembly 2 includes a fixed cover plate 21 and a connecting portion, and the movable cover plate 22 is connected to the base body 1 and / or the cover body. The fixed cover panels 21 of the body assembly 2 are connected through a locking structure that can separate the movable cover panel 22 from the fixed cover panel 21 .

[0024] The base body 1 is covered at the bottom of the grinding wheel. The inner cavity of the base body 1 is bucket-shaped, and its large opening is located above the small opening. The base body 1 is provided with a relief groove 2 provided for the rotating shaft of the power supply. The cover body assembly 2 covers the top and rear side of the grinding wheel and is located at the top rear side of the base 1 . The fixed cover plate 21 is fixedly connected with the base body 1, and the fixed cover plate 21 i...

Embodiment 2

[0028] The structural principle of this embodiment is basically the same as that of Embodiment 1, the difference is that the locking structure includes a backing plate, the backing plate is located inside the movable cover plate and is fixedly connected to the fixed cover plate, and the backing plate can be connected with the movable cover plate The edges are abutted, and can be connected by bolts and nuts after abutting.

[0029] In this embodiment, the movable cover plate is simply connected to the fixed cover plate, and there is no connection between the movable cover plate and the base body through relevant connecting pieces, so that when the grinding wheel needs to be replaced, the bolts and nuts are unloaded, and the movable cover plate can be taken away. Next, disengage the entire dust hood. The advantage of this is that the movable cover plate will affect the disassembly and assembly of the grinding wheel.

Embodiment 3

[0031] The structural principle of this embodiment is basically the same as that of Embodiment 1, except that the locking structure includes a hinge and a bead, and the movable cover plate is hinged to the base through the hinge; one end of the bead is hinged to the base through a bolt and nut, The other end can rely on the outer surface of the movable cover plate.

[0032]After the movable cover plate is combined with the fixed cover plate, swing the bead to make the other end of the bead lean against the outer surface of the movable cover plate, and then tighten the bolts and nuts to make the bead and the substrate fixedly connected. When the movable cover plate needs to be separated from the fixed cover plate, the bolts and nuts are first unscrewed, then the bead is swung to separate the other end of the bead from the movable cover plate, and finally the movable cover plate is swung to make the movable cover plate rotate around the hinge. The locking structure is simple in ...

Abstract

The invention provides a dust collecting cover of a grinding machine, which belongs to the technical field of machinery and is used for solving the technical problems of difficulty in disassembling and assembling and the like existing in the conventional dust collecting cover of a grinding machine. The dust collecting cover of the grinding machine is characterized by comprising a substrate covered at the bottom of a grinding wheel and a cover body assembly covered on the top and the back side part of the grinding wheel; the cover body assembly comprises a fixed cover plate and a movable cover plate positioned on one side of the fixed cover plate; the fixed cover plate is fixedly connected with the substrate; and the movable cover plate is connected with the substrate and / or the fixed cover plate of the cover body assembly through a locking structure which can be used for separating the movable cover plate from the fixed cover plate. According to the dust collecting cover of the grinding machine, the grinding wheel can be replaced only by separating the movable cover plate from the fixed cover plate by operating the locking structure without detaching the entire dust collecting cover, so that the dust collecting cover has the advantages of convenience in replacing the grinding wheel, reduction in the operating difficulty, and increase in the replacing efficiency; and repeated integral disassembly and assembly of the dust collecting cover are avoided, the damaging possibility of the dust collecting cover is lowered, and the service life of the dust collecting cover is prolonged.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a dust collecting cover of a grinder. Background technique [0002] Grinding machines, cutting machines, polishing machines and other equipment that work in the form of grinding and cutting usually produce a lot of chips and sparks during the processing of workpieces. Sanitation also affects the health and safety of staff, and sparks can easily cause fires. Therefore, when people manufacture equipment such as grinder, cutting machine, polishing machine, dust collecting cover is installed on equipment. The dust collecting hood can effectively gather the chips generated during the processing of the workpiece, so that the chips will not bounce around and the sparks will not splash randomly, so that the sanitation of the work site is improved to a certain extent, and the health and safety of the staff are improved. Assure. [0003] Existing dust collection covers are all one-piece,...
