[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] A grinding machine bar pin rotor structure includes a drive shaft 1. The drive shaft 1 is provided with a transmission key pin 13. A plurality of bracket assemblies 2 are sleeved outside the drive shaft 1. The bracket assembly 2 includes a bracket disc 21 and bar pins 3. The bracket disc 21 is provided with a plurality of hole slots 22, and the bar pins 3 are arranged in the hole slots 22.

[0027] The grinding machine bar pin rotor structure is composed of a drive shaft 1 and a plurality of stacked bracket assemblies 2. The bracket assembly 2 is formed by plastic injection molding, and the plastic material includes one of polyurethanes.

[0028] The bar pin 3 is adapted to the shape of the hole slot 22. A screw hole 31 is provided in the middle of the bar pin 3. The bar pin 3 and the screw hole 31 are fixedly connected to the bracket disc 21 by setting screws. An inner through hole 23 is provided inside the bracket disc 21. The inner through hole 23 is adapted to the outer diameter size of the drive shaft. A key pin slot 24 is provided at the edge of the inner through hole 23. The key pin slot 24 is in limit connection with the transmission key pin 13. The spacer sleeve 12 is provided with a groove corresponding to the transmission key pin 13, and is in limit connection with the transmission key pin 13 through the groove. The shape of the bracket disc 21 can be set as one of a square, a circle, and a polygon. The shape of the spacer sleeve 12 can be set as one of a square, a circle, and a polygon. The drive shaft 1 is connected to the output shaft of the power source, and the drive shaft 1 is rotated by the output shaft of the power source. A spacer sleeve 12 is provided between the bracket assemblies 2, which can be increased according to the usage requirements of customers.

[0029] Working principle: First, a spacer sleeve 12 is sleeved on the outer bottom of the drive shaft 1. A transmission key pin 13 is provided on the outer surface of the drive shaft 1, and the spacer sleeve 12 is provided with a groove. After they are correspondingly sleeved, they can be limited and fixed. Then, the bracket disc 21 is installed. The bracket disc 21 is provided with a key pin slot 24, and the key pin slot 24 also matches the shape of the transmission key pin 13. In this way, the sleeved bracket disc 21 can be limited and fixed. Then, the above steps are sequentially installed. A plurality of bar pins 3 are provided around the outer circumference of the bracket disc 21. After all the above kits are installed, they are put into the machine. The drive shaft 1 is connected to the output shaft of the power source of the machine. When the machine power source rotates, the drive shaft 1 is driven to rotate, thereby driving the entire grinding assembly to rotate.

[0030] It should be noted that a shaft step is provided at the bottom of the drive shaft 1, so that when the spacer sleeve 12 is inserted, it can be limited, that is, the outer diameter of the shaft step is larger than the inner diameter of the spacer sleeve 12, which plays a supporting role. The spacer sleeve can be separated or integrated with the bracket assembly. In addition, the drive shaft 1 is connected to the power source output shaft of the machine, and these are all existing connection methods, so these existing connection and fixation methods will not be elaborated.

[0031] In addition, the drive shaft 1 of this patent can be set as a square structure, so that the transmission key pin 13 can be cancelled, which is convenient for installation and use. These are all existing technical solutions and can be selected according to the needs of customers.
