Examples

The embodiment provides a dynamic balance grinder, which passes a workpiece below a grinding mechanism 2, a driving mechanism 3 drives the grinding mechanism 2 to work, and the grinding mechanism 2 can polish and grind the workpiece. In the grinding process, because the grinding mechanism 2 is in contact with a workpiece, the grinding unit 20 in the grinding mechanism 2 is likely to be stressed unevenly so as to cause the grinding unit 20 to deviate and fall off, and the deviation correcting unit 21 is arranged to dynamically correct the deviation of the grinding unit 20 in time, so that the grinding unit 20 is always positioned in a proper station. After long-time grinding, the parts in the grinding unit 20 are worn and need to be replaced in time, the grinding unit 20 is loosened by controlling the tensioning adjusting unit 22, the parts can be directly replaced by the workers conveniently, the grinding mechanism 2 does not need to be detached to be replaced, and the working efficiency of the equipment is greatly improved.

Specifically, the grinding unit 20 includes a grinding belt 200, a driving wheel 201 and a driven wheel 202, the grinding belt 200 is sleeved on the periphery of the driving wheel 201 and the driven wheel 202, the driving wheel 201 is in transmission connection with a transmission mechanism, the driving wheel 201 is driven by the transmission mechanism, the driven wheel 202 is driven by the grinding belt 200 to rotate, when the grinding belt 200 is ground for a long time, the grinding belt 200 is worn, and therefore needs to be replaced frequently, when the grinding belt is replaced, the tensioning adjusting unit 22 pulls the driven wheel 202 towards the driving wheel 201, the distance between the driving wheel 201 and the driven wheel 202 is reduced, so that the grinding belt 200 is loosened and falls off, the grinding belt 200 can be replaced, the tensioning adjusting unit 22 resets after the replacement is completed, the driving wheel 201 and the driven wheel 202 tension the grinding belt 200 again, and the replacement of the grinding belt 200 is completed.

Wherein, the driven wheel 202 is always positioned in the chute 10 of the main frame 1 in the moving process, the movement of the driven wheel 202 is more stable under the guiding action of the chute 10, and the situation that the driven wheel 202 is separated is avoided.

Specifically, the tensioning and adjusting unit 22 includes a push rod 220, a first driving assembly 221 and a guiding assembly 222, when the abrasive belt 200 is adjusted, the first driving assembly 221 pushes the push rod 220 to move towards the driving wheel 201, the guiding assemblies 222 at two ends of the push rod 220 are connected with two ends of the driven wheel 202, the driven wheel 202 is driven to move towards the driving wheel 201 in the pushing process, after the abrasive belt 200 is replaced, the first driving assembly 221 drives the push rod 220 to reset, and the guiding assembly 222 also pushes back the driven wheel 202 to re-tension the abrasive belt 200.

Specifically, in the process of grinding a workpiece, the grinding belt 200 may be uneven in hand and may shift, the second driving assemblies 210 at the two ends of the main frame 1 may individually control each second driving assembly 210 according to the different shifting directions and shifting degrees of the grinding belt 200, each second driving assembly 210 individually acts on one end of the push rod 220, a single second driving assembly 210 is started to push one end of the push rod 220, the push rod 220 further shifts, and at this time, the guide assembly 222 at the same side is also pushed, so that one end corresponding to the driven wheel 202 tilts, the grinding belt 200 moves along the tilting direction, when the grinding belt 200 returns to the working position, the second driving assembly 210 resets, and further, the driven wheel 202 resets.

Wherein, set up elastic component 211 between tensioning adjustment unit 22 and driven round 202, can play the cushioning effect, make the process of rectifying a deviation more steady.

The connection between the driving end of the first driving assembly 221 and the push rod 220 is configured as a slot, when the second driving assembly 210 acts on the push rod 220, the push rod 220 will incline, and the slot is configured such that the driving end of the first driving assembly 221 can slide in the slot, thereby avoiding interference between devices.

Specifically, the third driving assembly 30 drives the driving gear 32 to rotate, and drives the transmission gear 31 to rotate through transmission connection, and the transmission gear 31 is sleeved on the driving wheel 201, so as to drive the grinding mechanism 2 to rotate, thereby realizing grinding of the workpiece.
