[0022] The driving motor 103 and the grinding motor 204 are electrically connected to an external power supply and a control device. The specific structure and working principle thereof are existing mature technologies and will not be described in detail here.

[0023] In addition, according to an embodiment of the present invention, Figure 3 and Figure 4As shown, a synchronous rod 2041 is provided at one end of the rotating shaft of the grinding motor 204, and a transmission protrusion 2042 is provided on the outside of the rod body of the synchronous rod 2041, a synchronous groove 3031 is provided inside the transmission gear 303, and the transmission protrusion 2042 is inserted into the inside of the synchronous groove 3031. In use, when the grinding motor 204 rotates, it can drive the synchronous rod 2041 to rotate.

A grinding gear 3021 is provided at one end of the grinding roller 302, and the grinding gear 3021 is connected to the transmission gear 303 in transmission. The transmission gear 303 can drive the grinding roller 302 to rotate through the grinding gear 3021, thereby realizing the grinding operation. Moreover, this transmission method makes it possible for the grinding motor 204 to stably drive the two grinding mechanisms 3 to perform normal grinding work even if the position of the positioning seat 301 changes, and the use is stable.

[0024] In addition, according to an embodiment of the present invention, Figure 4 As shown, the grinding mechanism 3 also includes a pressure rod 304, which is fixedly mounted on the side of the positioning seat 301, and the rod body of the pressure rod 304 passes through the side of the frame of the positioning bracket 203.

[0026] In addition, according to an embodiment of the present invention, Figure 4As shown, the outside of the rod body of the pressure rod 304 is sleeved with a grinding top spring 3043, and the two ends of the grinding top spring 3043 are respectively fixedly connected to the side of the control baffle 306 and the side of the positioning bracket 203. In use, when the device is grinding the circular tubular accessories, the circular tubular accessories are fixed inside the accessory fixture 104, and then the grinding rollers 302 of the two grinding mechanisms 3 are respectively applied to the inner surface and outer surface of the circular tubular accessories. At this time, the grinding rollers 302 will be against the surface of the circular tubular accessories under the action of the grinding top spring 3043, which is convenient for later learning to adjust the grinding pressure and grinding depth.

During use, the grinding pressure of the device can be adjusted by rotating the pressure regulating rod 305. When the pressure regulating rod 305 rotates, the pressure regulating rod 305 drives the control baffle 306 to move back and forth through the rod body thread to change the use position, thereby changing the initial compression length of the grinding top spring 3043, that is, changing the grinding pressure between the grinding roller 302 and the surface of the accessory, and the adjustment is flexible and convenient.

[0028] In addition, according to an embodiment of the present invention, Figure 4 As shown, the displacement rod 202 has a thread on the outside of the rod body, and the displacement rod 202 is screwed to the inside of the positioning bracket 203 through the rod body thread. During use, when the displacement rod 202 is rotated, the positioning bracket 203 can move laterally to change the use position of the grinding mechanism 3, thereby being able to adapt to the grinding operations on accessories of different specifications.

[0029] In addition, according to an embodiment of the present invention, Figure 2 As shown, two symmetrical groups of grinding mechanisms 3 are provided inside the positioning bracket 203. During use, the two groups of grinding mechanisms 3 can be synchronously driven by the grinding motor 204 for grinding, so that the two groups of grinding mechanisms 3 can act on the inner and outer surfaces of the circular tubular accessories respectively for simultaneous grinding, which greatly improves the grinding efficiency and is convenient and flexible to use.

[0030] Specific usage and function of this embodiment: In the present invention, when grinding a circular tubular accessory, the circular tubular accessory is fixed inside the accessory fixture 104, and then the grinding rollers 302 of the two grinding mechanisms 3 act on the inner surface and outer surface of the circular tubular accessory respectively. At this time, the grinding rollers 302 will press against the surface of the circular tubular accessory under the action of the grinding top spring 3043. According to the actual processing requirements, the grinding pressure and the maximum grinding depth of the inner surface of the accessory are adjusted. The two sets of grinding mechanisms 3 are independent of each other and do not interfere with each other, so as to adapt to different grinding requirements of the inner and outer surfaces of the accessories. The grinding pressure of the device can be adjusted by rotating the pressure regulating rod 305. When the pressure regulating rod 305 is rotated, the pressure regulating rod 305 drives the control baffle 306 to move forward and backward through the rod body thread to change the use position, thereby changing the initial compression length of the grinding top spring 3043, that is, changing the grinding pressure between the grinding roller 302 and the surface of the accessory. The adjustment is flexible and convenient. At the same time, the maximum grinding depth of the grinding mechanism 3 can be changed by rotating the limit block 3041. When the limit block 3041 is rotated, the limit block 3041 can be adjusted by the pressure rod 304 The external thread moves outside the pressure rod 304, thereby changing the maximum grinding depth of the positioning seat 301. After the adjustment is completed, the power of the driving motor 103 and the grinding motor 204 is turned on. The driving motor 103 drives the cylindrical fitting to rotate. The grinding motor 204 can drive the two grinding mechanisms 3 at the same time, thereby realizing the use requirements of the synchronous grinding processing of the two sets of grinding mechanisms 3. When the grinding motor 204 rotates, it can drive the synchronous rod 2041 to rotate. When the synchronous rod 2041 rotates, the transmission protrusion 2042 can drive the transmission gear 3031 through the synchronous groove 3031. 3 rotates, and the transmission gear 303 can drive the grinding roller 302 to rotate through the grinding gear 3021, so as to realize the grinding operation. Moreover, this transmission mode makes it possible for the grinding motor 204 to stably drive the two grinding mechanisms 3 to perform normal grinding work even if the position of the positioning seat 301 changes. Under the cooperation with the driving motor 103, the inner and outer surfaces of the circular tubular accessories can be ground simultaneously. After the grinding process is completed, the power of the driving motor 103 and the grinding motor 204 is turned off, and the accessories can be removed from the accessory fixture 104.

[0031] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
