[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Example 1, by Figure 1 The present invention relates to a composite ceramic grinding wheel, comprising a base 1, a mounting hole 4 in the middle of the base 1, multiple wheel pieces 3 at equal angles at the bottom of the base 1, a fixing mechanism 2 at the top of the base 1, and a certain distance between adjacent wheel pieces 3 to facilitate chip removal.

[0025] Specifically, by Figures 2-4 The fixing mechanism 2 includes a top cylinder 201 fixed at the center of the top of the base 1. The inner diameter of the top cylinder 201 is larger than the inner diameter of the mounting hole 4. An annular groove 208 is provided on the outer side of the top cylinder 201. Multiple inner shafts 207 are rotatably connected at equal angles in the annular groove 208. The bottom end of each inner shaft 207 is rotatably connected to the top of the base 1. A retaining plate 209 is fixedly sleeved on the outer side of each inner shaft 207. Multiple mounting grooves 6 are provided at equal angles on the base 1. A mounting plate 203 is fixedly connected to the top of each wheel 3. Each mounting plate 203 passes through each mounting groove 6. Each mounting plate 203 is provided with a retaining groove 2010. Each retaining plate 209 is inserted into each retaining groove 2010. Reinforcing columns 5 are provided on both sides of the wheel 3. The reinforcing columns 5 are fixed to the bottom of the base 1. By setting the reinforcing columns 5, the wheel 3 is limited, thereby ensuring the stability of the wheel 3 after installation.

[0026] In use, first place the wheel 3 at the bottom of the base 1 so that the mounting plate 203 passes through the mounting groove 6. Then rotate the clamping plate 209 so that the clamping plate 209 is inserted into the clamping groove 2010 to support the mounting plate 203, thereby installing the wheel 3 at the bottom of the base 1. When the clamping plate 209 rotates and disengages from the clamping groove 2010, the supporting effect on the mounting plate 203 is released, and the wheel 3 can be removed from the bottom of the base 1. Thus, the damaged wheel 3 can be replaced individually without replacing the whole wheel 3.

[0027] Specifically, by Figures 3-5 As shown, a lifting ring 2014 is movably sleeved on the outer side of the top cylinder 201. Multiple connecting posts 2017 are fixedly connected at equal angles to the outer side of the lifting ring 2014. An insert plate 2016 is fixedly sleeved on the outer side of each connecting post 2017. Each locking plate 209 has a slot 2011 on its top, and each insert plate 2016 is inserted into its respective slot 2011. A top ring 204 is fixedly connected to the top of the base 1. Multiple through slots 206 are provided at equal angles on the top ring 204, and each mounting plate 203 passes through each through slot 206. The top ring 204... Multiple guide posts 2013 are fixedly connected at equal angles between the top of 04 and the outer side of the top cylinder 201. Guide rings 2015 are movably sleeved between each guide post 2013. The end of each connecting post 2017 away from the lifting ring 2014 is fixed to the top of the guide ring 2015. The top of the lifting ring 2014 is provided with a threaded cylinder 202. A turntable 2012 is fixedly installed on the outer side of the threaded cylinder 202. The outer side of the top cylinder 201 is provided with an external thread 205. The threaded cylinder 202 is threadedly sleeved on the outer side of the top cylinder 201 through the external thread 205.

[0028] In use, when the card plate 209 is inserted into the card slot 2010, the top cylinder 201 is moved downwards. The guide ring 2015 is driven to slide downwards along the guide post 2013 via the connecting post 2017. At the same time, the insert plate 2016 descends until it is inserted into the slot 2011, limiting the card plate 209 to prevent it from rotating. Then, the turntable 2012 is rotated clockwise, causing the threaded cylinder 202 to rotate clockwise on the outside of the top cylinder 201. Since the threaded cylinder 202 is threaded onto the outside of the top cylinder 201 through the external thread 205, the threaded cylinder 202 moves downwards while rotating until it abuts against the lifting ring 2014 to prevent the lifting ring 2014 from moving. Finally, the wheel 3 is firmly installed at the bottom of the base 1.
