The fixing assembly includes two fastening nuts, two fixing plates, four first fixing bolts, four fixing nuts, twelve threaded holes, and the grinding wheel body. The beneficial effects of this utility model are: the drive motor drives the rotating shaft to rotate for grinding and cutting; the two fastening nuts, in conjunction with the rotating shaft, first fix the fixing plates and the grinding wheel body; the two fixing plates are fitted and fixed to the grinding wheel body; the first fixing bolts and fixing nuts are used to fix the two fixing plates; the fixing assembly allows the grinding wheel body to be installed and fixed; and after installation, the grinding wheel body can be tightened.

[0004] However, when changing the grinding wheel, the grinding machine needs to be stopped, the old grinding wheel needs to be removed, and the new grinding wheel needs to be installed. This process takes a long time and affects the normal use of the grinding machine. Therefore, a grinding wheel that is easy to disassemble and install is proposed to solve the problems mentioned above. Utility Model Content

[0013] Furthermore, a mating bolt is provided on one side of the pad, and a mating nut is threaded onto the surface of the mating bolt.

[0014] Furthermore, a reinforcing rib is fixedly installed on one side of the mounting plate, and the bottom of the reinforcing rib is fixedly connected to the rotating base.

[0015] Furthermore, a shift motor is fixedly installed at the bottom of the installation platform, and the output shaft of the shift motor is fixedly connected to the rotating base. Support legs are fixedly installed at the four corners of the bottom of the installation platform.

[0016] Compared with the prior art, this utility model provides a grinding wheel that is easy to disassemble and install, and has the following beneficial effects:

[0017] This easily disassembled and installed grinding wheel utilizes a rotating base mounted on top of a mounting platform. Two mounting plates are positioned on top of the rotating base, and a rotating shaft is mounted on each mounting plate. During use, a new grinding wheel is installed onto the rotating shaft, which is not connected to the drive sleeve. When a grinding wheel needs to be replaced, the rotating base rotates, swapping the two mounting plates and aligning the new grinding wheel with the drive sleeve. The drive sleeve is then connected to the rotating shaft. While continuing operation, the old grinding wheel can be replaced at the unconnected station, reducing downtime and improving grinding wheel replacement efficiency. This solves the problem of common grinding wheel replacement methods that require stopping the machine, removing the old grinding wheel, and installing the new one, a time-consuming process that disrupts the normal use of the grinding wheel.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4This embodiment of an easy-to-disassemble and install grinding wheel includes a mounting platform 1, a rotating base 2 rotatably mounted on the top of the mounting platform 1, two mounting plates 3 fixedly mounted on the top of the rotating base 2, a rotating shaft 4 rotatably mounted on one side of the mounting plate 3 via a bearing, and a separate drive assembly fixedly mounted on the top of the mounting platform 1.

[0025] The separate drive assembly includes a fixed upright plate 5 fixedly installed on the top of the mounting platform 1. A docking cylinder 6 is fixedly installed on one side of the fixed upright plate 5. A docking mounting plate 7 is fixedly installed on the movable end of the docking cylinder 6. A drive sleeve 8 is fixedly installed on one side of the docking mounting plate 7. The drive sleeve 8 is aligned with one of the rotating shafts 4. A limit strip 9 is fixedly installed on the surface of the rotating shaft 4. A limit groove 10 adapted to the limit strip 9 is opened on the inner side wall of the drive sleeve 8. The limit strip 9 is engaged in the limit groove 10, so that when the drive sleeve 8 rotates, it drives the rotating shaft 4 to rotate.

[0026] Secondly, a drive motor 11 is fixedly installed on one side of the fixed plate 5, and the output shaft of the drive motor 11 is fixedly connected to one side of the drive sleeve 8.

[0027] Specifically, the drive motor 11 drives the drive sleeve 8 to rotate, which in turn drives one of the rotating shafts 4 to rotate. During replacement, the docking cylinder 6 drives the docking mounting plate 7 to move, which in turn drives the drive sleeve 8 to move, causing the drive sleeve 8 to separate from the rotating shaft 4. The rotating base 2 rotates, causing the two rotating shafts 4 to switch positions. The docking cylinder 6 drives the docking mounting plate 7 to return to its original position, causing the drive sleeve 8 to dock with the rotating shaft 4.

[0028] Please see Figure 1 In this embodiment, a mounting screw 12 is fixedly installed at the end of the rotating shaft 4 away from the drive sleeve 8, and two mounting nuts 13 are threadedly connected to the surface of the mounting screw 12.

[0029] Two pads 14 are slidably mounted on the surface of the rotating shaft 4, and the pads 14 are located between two mounting nuts 13.

[0030] Meanwhile, a grinding wheel 15 is slidably mounted on the surface of the rotating shaft 4. The grinding wheel 15 is located between two pads 14, and through holes aligned with each other are opened on one side of the grinding wheel 15 and the pads 14.

[0031] One side of the pad 14 is provided with a mating bolt 16, and the surface of the mating bolt 16 is threaded with a mating nut 17. The grinding wheel 15 is mounted to the surface of the mounting screw 12 by means of two mounting nuts 13, the mating bolt 16, and the mating nut 17.

[0032] When changing the grinding wheel 15, the two grinding wheels 15 are swapped to quickly replace the new grinding wheel 15 for use. When using the new grinding wheel 15, the old grinding wheel 15 is replaced in another position to reduce downtime.

[0033] Please see Figure 1 and Figure 2 In this embodiment, a reinforcing rib plate 18 is fixedly installed on one side of the mounting plate 3, and the bottom of the reinforcing rib plate 18 is fixedly connected to the rotating base 2.

[0034] The mounting platform 1 has a fixedly mounted transposition motor 19 at its bottom. The output shaft of the transposition motor 19 is fixedly connected to the rotating base 2. Support legs 20 are fixedly mounted at each of the four corners of the bottom of the mounting platform 1. The transposition motor 19 is a servo motor, which drives the rotating base 2 to rotate 180 degrees with each start.

[0035] The working principle of the above embodiment is as follows: the drive motor 11 drives the drive sleeve 8 to rotate, which in turn drives one of the rotating shafts 4 to rotate. When the grinding wheel 15 is replaced, the docking cylinder 6 drives the docking mounting plate 7 to move, which in turn drives the drive sleeve 8 to move, so that the drive sleeve 8 is separated from the rotating shaft 4. The rotating base 2 rotates, which drives the two rotating shafts 4 to switch positions. The docking cylinder 6 drives the docking mounting plate 7 to return to its original position, which drives the drive sleeve 8 to dock with the rotating shaft 4.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
