Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a grinding machine. Background Technology

[0002] The grinder includes a handle, a grinding motor mounted on the upper left side of the handle, and a grinding disc mounted on the lower left side of the handle. The grinding motor has an output shaft, the grinding disc has a grinding disc shaft, the output shaft is connected to the grinding disc shaft, and the grinding disc has a lower grinding surface. In the prior art, only one grinding disc is installed on the grinder. During the operation of the grinding disc, there is a swinging force, which causes it to run unbalanced, making it prone to accidents and inconvenient to use. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned shortcomings by providing a grinding machine that operates more smoothly and is safer to use—a four-disc grinding machine.

[0004] The technical solution of this utility model is implemented as follows: a four-disc grinding machine includes a handle, a grinding motor installed on the upper left side of the handle, and a grinding disc installed on the lower left side of the handle. The grinding motor has an output shaft, the grinding disc has a grinding disc shaft, the output shaft is connected to the grinding disc shaft, and the grinding disc has a lower grinding surface. Its characteristic is that there are four grinding discs arranged in a circumferential array below the handle. Two sets of diagonally opposite grinding discs are formed, namely the first set and the second set. In terms of connection, the connection between the output shaft and the first set of diagonally opposite grinding discs differs from the connection between the output shaft and the second set by one intermediate transmission wheel, causing adjacent grinding discs to rotate in opposite directions.

[0005] The beneficial effects of this invention are that such a grinder has the advantages of more stable operation and safer use. Attached Figure Description

[0011] The present invention will be further described below with reference to the accompanying drawings.

[0012] like Figure 1 , 2 As shown in Figure 3, a four-disc grinding machine includes a handle 1, a grinding motor 2 mounted on the upper left side of the handle, and a grinding disc 3 mounted on the lower left side of the handle. The grinding motor has an output shaft 21, and the grinding disc has a grinding disc shaft 4. The output shaft is connected to the grinding disc shaft, and the grinding disc has a lower grinding surface 31. Its characteristic is that there are four grinding discs: a first grinding disc 3a, a second grinding disc 3b, a third grinding disc 3c, and a fourth grinding disc 3d. These four grinding discs are arranged in a circumferential array below the handle. There are two sets of diagonally opposite grinding discs: the first set and the second set. Specifically, the first grinding disc 3a and the third grinding disc 3c form one set of diagonal grinding discs, and the second grinding disc 3b and the fourth grinding disc 3d form another set. In terms of connection, the connection between the output shaft and the first set of diagonal grinding discs differs from the connection between the output shaft and the second set of diagonal grinding discs by an intermediate transmission wheel 5, causing adjacent grinding discs to rotate in opposite directions.

[0013] In one technical solution, the output shaft is connected to a combined gear 22, which includes an upper gear 221 and a lower gear 222. The upper gear and the lower gear are an integral structure. The grinding disc shafts of the grinding discs are connected to gears respectively. The gears on the four grinding disc shafts are gears 32a, 32b, 32c, and 32d. Gear 32a directly meshes with the upper gear 221, and gear 32c directly meshes with the upper gear 221. The intermediate transmission wheel includes two intermediate transmission shafts 52 and intermediate transmission wheel gears 51 mounted on the two intermediate transmission shafts. These two intermediate transmission gears are 51b and 51d respectively. The lower gear 222 meshes with gear 32b via intermediate transmission wheel gear 51b, and the lower gear also meshes with gear 32d via intermediate transmission wheel gear 51d.

[0014] exist Figure 4 In the diagram, the direction of arrow F is the direction in which the grinding disc rotates.

[0015] The above-mentioned features of this utility model have the advantage of more stable operation and can achieve the purpose of this utility model.

[0016] In one technical solution, the combined gear and the gear connected to the grinding disc shaft have a housing 6 outside.

[0017] In one technical solution, the combined gears ensure that the four grinding discs rotate at the same circumferential speed.

[0018] In one technical solution, the four grinding discs are of the same size and model.

[0019] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

Claims

1. A four-disc grinding machine, comprising a handle, a grinding motor mounted on the upper left side of the handle, and a grinding disc mounted on the lower left side of the handle; the grinding motor has an output shaft, the grinding disc has a grinding disc shaft, the output shaft is connected to the grinding disc shaft, and the grinding disc has a lower grinding surface; characterized in that: There are four grinding discs, which are arranged in a circular array below the handle. The four grinding discs are arranged diagonally in two groups, namely the first group and the second group. In terms of connection, the connection between the output shaft and the first group of diagonal grinding discs is different from the connection between the output shaft and the second group of diagonal grinding discs by one intermediate transmission wheel, so that the adjacent grinding discs rotate in opposite directions.
