In the application, the first grinding machine 3, the second grinding machine 4 and the mechanical arm 2 form a work station, the first grinding machine 3 and the second grinding machine 4 are independent grinding equipment, therefore, the first grinding machine 3 and the second grinding machine 4 can be arranged to be spaced according to the requirement of the rotation space of the mechanical arm 2, and the space between the first grinding machine 3 and the second grinding machine 4 can meet the rotation of the mechanical arm 2, so that the debugging time can be shortened, and the programming difficulty can be reduced. In addition, the first grinding machine 3 and the second grinding machine 4 are provided with a plurality of grinding stations, and different grinding stations can be selected according to actual requirements in a combined mode. For example, for most types of handles and three-way workpieces, all surface grinding can be performed on two grinding wheels nearby, and the mechanical arm 2 has small motion amplitude and short time.

According to the multi-station grinding machine provided by the embodiment of the invention, the first grinding machine and the second grinding machine are arranged at intervals, the first grinding machine is provided with a plurality of first grinding wheels, the second grinding machines are provided with a plurality of second grinding wheels, the space between the first grinding machine and the second grinding machine can allow the mechanical arm to turn over, so that the debugging time is reduced, the programming difficulty is reduced, the grinding requirements of complex workpieces can be met by the plurality of grinding stations, the mechanical arm does not need to rotate greatly, the grinding time is short, and the grinding efficiency is high.

It will be appreciated that the second motor may be assembled in the same manner and will not be described in detail herein.

Further, as shown in fig. 1 and 2, the plurality of first grinding wheels 31 constitute a plurality of first grinding wheel groups, each of the first grinding wheel groups includes two adjacent first grinding wheels 31, one of the two adjacent first grinding wheels 31 is rotatably connected to the housing of the first grinding machine 3 through a first transmission shaft (not shown), the first motor 32 drives the first transmission shaft to rotate through a transmission belt, the plurality of second grinding wheels 41 constitute a plurality of second grinding wheel groups, each of the second grinding wheel groups includes two adjacent second grinding wheels 41, one of the two adjacent second grinding wheels 41 is rotatably connected to the housing of the second grinding machine 4 through a second transmission shaft, and the second motor drives the second transmission shaft to rotate through the transmission belt.

Specifically, as shown in fig. 1, the first grinding machine 3 includes four first grinding wheels 31, wherein two first grinding wheels 31 located above constitute one first grinding wheel group, two first grinding wheels 31 located below constitute one first grinding wheel group, and two first grinding wheels 31 located opposite to each other in the middle are rotatably connected to the housing of the first grinding machine 3 through a first transmission shaft, so that the first motor 32 can simultaneously drive the two first transmission shafts to rotate through a transmission belt, so that the first motor 32 can simultaneously drive the four first grinding wheels 31. Similarly, the second motor can also drive the four second grinding wheels to rotate at the same time, and the description is omitted here.

In other words, one motor can drive a plurality of grinding wheels, so that the number of motors can be reduced, and the cost is saved.

Further, as shown in fig. 1, the two first grinding wheels 31 of each first grinding wheel set are of different diametric size and/or the two second grinding wheels 41 of each second grinding wheel set are of different diametric size. Therefore, the motor can control the grinding wheels with different sizes to run, and when a workpiece with a simple structure is ground, the number of the grinding machines to be started can be reduced, for example, when a large-size grinding wheel and a small-size grinding wheel can meet the grinding requirement of the workpiece, only one grinding machine needs to be started, so that the cost is saved, and the use mode of the workstation is optimized.
