[0019] Technical effects and advantages of the present invention:

[0020] 1. The present invention controls the extended end of the cylinder to extend from half the length to the longest, and the grinding rod extends into the mounting hole of the diamond roller. The inner wall of the mounting hole of the diamond roller is deburred through the back side of one end of the grinding rod, and the push rod cooperates with the supporting roller to provide a flipping thrust to the supporting rod, so that the baffle plate rises to half of the mounting hole of the diamond roller. When the water pump is turned on, the level of clean water in the mounting hole of the diamond roller rises and overflows from the top of the baffle plate. During the overflowing process, the clean water can conveniently wash away the grinding chips attached to the back side of the grinding rod to avoid affecting the efficiency of the grinding rod in accurately grinding the mounting hole of the diamond roller. In this process, the flip frame is driven to rotate by the second lever, and the push-pull rod is pulled horizontally by the first lever to move horizontally, so that the first piston moves to the side of the water inlet pipe away from the control tooling, so that the clean water in the water tank enters the mounting hole of the diamond roller to cool the grinding rod and the diamond roller.

[0021] 2. The present invention controls the extended end of the cylinder to contract to the shortest state, closes the control valve, and allows clean water to enter the bladder. When the extended end of the cylinder is in the shortest state, the second piston slides to the side of the water inlet pipe away from the flip frame, and one end of the grinding rod reaches the cleaning station. At this time, the adjustment roller slides from the trapezoidal block to the movable table, and the groove is close to the grinding rod. Clean water will be sprayed onto the grinding rod through the hose to clean the grinding chips stuck on the rough surface of the grinding rod. At the same time, the control valve is opened to allow the clean water in the bladder to flush the grinding chips in the mounting hole of the diamond roller along the water injection pipe. This process can simultaneously clean the mounting hole of the diamond roller and the surface of the grinding rod, and ensure the water pressure when flushing the surface of the grinding rod.

[0033] When the extended end of the control cylinder 207 is contracted to the shortest, the control valve is closed, so that the clean water that enters the working cylinder 214 but is not discharged through the water injection pipe 211 pushes open the one-way valve and enters the bladder 213.

[0039] The flip frame 205 is driven to rotate by the second lever 206, and the push-pull rod 203 is pulled horizontally by the first lever 204, so that the first piston 215 moves to the side of the water inlet pipe 201 away from the control tooling 5, so that the clean water in the water tank 7 enters the installation hole of the diamond roller to cool the grinding rod 210 and the diamond roller.

[0040] See also Figure 3-Figure 4 As shown, the cleaning unit 209 includes a first square rod 293 movably inserted on the inner wall of the protective cover 6, one end of the first square rod 293 is fixedly connected to a moving block 291, a thrust spring is elastically arranged between the moving block 291 and the inner wall of the protective cover 6, and a groove is opened on the side of the moving block 291 facing the grinding rod 210, and there is a gap between the groove and the grinding rod 210, and a hose 292 is fixedly inserted on the side of the moving block 291 away from the groove, and the input end of the hose 292 is connected to the working cylinder 214;

[0041] The adjusting roller 294 slides from the trapezoidal block 295 to the movable platform 208, and the groove is close to the grinding rod 210. Clean water will be sprayed onto the grinding rod 210 through the hose 292 to clean the grinding chips stuck on the rough surface of the grinding rod 210.

[0042] See also Figure 3-Figure 4 As shown, a trapezoidal block 295 is fixedly installed on the back of the moving platform 208, and an adjusting roller 294 is provided on the moving block 291 which is rotated toward the side of the moving platform 208, and the position of the adjusting roller 294 corresponds to the position of the trapezoidal block 295;

[0043] In this embodiment, the extended end of the cylinder 207 is controlled to extend from half the length to the longest, and the grinding rod 210 is extended into the mounting hole of the diamond roller. The inner wall of the mounting hole of the diamond roller is deburred by the back side of one end of the grinding rod 210, and the top rod 901 cooperates with the supporting roller to provide a turning thrust to the supporting rod 905, so that the shielding plate 902 rises to cover half of the mounting hole of the diamond roller. When the water pump 1 is turned on, the clean water level in the mounting hole of the diamond roller rises and overflows from the top of the shielding plate 902.

[0044] When the clean water overflows, it is convenient to wash away the grinding chips attached to the back of the grinding rod 210, so as to avoid affecting the efficiency of the grinding rod 210 in accurately grinding the diamond roller mounting hole. In this process, the second lever 206 drives the flip frame 205 to rotate, and cooperates with the first lever 204 to pull the push-pull rod 203 to move horizontally, so that the first piston 215 moves to the side of the water inlet pipe 201 away from the control tooling 5, so that the clean water in the water tank 7 enters the mounting hole of the diamond roller, thereby cooling the grinding rod 210 and the diamond roller.

[0045] Example 2: Please refer to Figure 2 , Figure 5 and Figure 6 As shown, the problem that the grinding chips are easily stuck in the rough parts of the grinding rod due to the rough surface, making it inconvenient to clean efficiently can be solved by the following solution;

[0046] In this embodiment, the shielding mechanism 9 includes a guide seat 8 fixedly arranged on the top of the base 4, and the side of the guide seat 8 is fixedly connected to a guide sleeve 903 through two connecting frames 909. The internal sliding sleeve of the guide sleeve 903 is provided with a second square rod 904, and the bottom of the second square rod 904 is fixedly connected to a fixing pin 906.

[0047] See also Figure 5-Figure 6 As shown, a shielding plate 902 is fixedly installed on the top of the second square rod 904, the position of the shielding plate 902 corresponds to the position of the diamond roller mounting hole, and there is a gap between the shielding plate 902 and the diamond roller mounting hole.

[0048] See also Figure 5-Figure 6 As shown, the middle parts of the two connecting frames 909 are fixedly connected with a rotating seat 907, a support rod 905 is rotatably arranged between the two rotating seats 907 through a rotating shaft, one end of the support rod 905 is slidably connected with a fixing pin 906, and a blocking block 908 for positioning the support rod 905 is fixedly installed on one rotating seat 907, and the blocking block 908 is located above the support rod 905;

[0049] In the process of controlling the extended end of the cylinder 207 to be retracted to the shortest, the control valve is closed to allow clean water to enter the leather bag 213. When the extended end of the cylinder 207 is in the shortest state, the second piston 202 slides to the side of the water inlet pipe 201 away from the flip frame 205, and one end of the grinding rod 210 reaches the cleaning station. At this time, the adjusting roller 294 slides from the trapezoidal block 295 to the moving table 208, and the groove is close to the grinding rod 210. Clean water will be sprayed onto the grinding rod 210 through the hose 292 to clean the grinding chips stuck on the rough surface of the grinding rod 210;

[0050] At the same time, the control valve is opened to allow the clean water in the bladder 213 to flush the grinding chips in the mounting hole of the diamond roller along the water injection pipe 211. This process can simultaneously clean the mounting hole of the diamond roller and the surface of the grinding rod 210, and ensure the water pressure when flushing the surface of the grinding rod 210.

[0051] See also Figure 6 As shown, the top of the guide seat 8 is slidably connected to the bottom of the movable platform 208, a top rod 901 is connected to the bottom of the side of the movable platform 208, and the other end of the top rod 901 is rotatably connected to a support roller, and the position of the support roller corresponds to the position of the support rod 905.

[0053] See also Figure 1-Figure 2 As shown, a control tool 5 for driving the clamping tool 10 to rotate is fixedly embedded in the side wall of the protective cover 6, and the control tool 5 is a prior art.

[0054] Working principle: When the present invention is used, the diamond roller is fixed by the clamping tool 10, and then the control tool 5 is turned on to make the diamond roller rotate;

[0055] The extended end of the control cylinder 207 is extended from half the length to the longest, and the moving platform 208 drives the grinding rod 210 to move horizontally, so that the grinding rod 210 extends into the mounting hole of the diamond roller, and the inner wall of the mounting hole of the diamond roller is deburred by the back side of one end of the grinding rod 210, and the top rod 901 cooperates with the supporting roller to provide a turning thrust to the supporting rod 905, so that the second square rod 904 and the shielding plate 902 rise;

[0056] When the shielding plate 902 rises to half-block the mounting hole of the diamond roller, the water pump 1 is turned on, and the level of clean water in the mounting hole of the diamond roller rises and overflows from the top of the shielding plate 902, so that the clean water can easily wash away the grinding debris attached to the back of the grinding rod 210 during the overflow process, thereby avoiding affecting the efficiency of the grinding rod 210 in accurately grinding and trimming the mounting hole of the diamond roller;

[0057] During this process, the second lever 206 drives the flip frame 205 to rotate, and the first lever 204 pulls the push-pull rod 203 to move horizontally, so that the first piston 215 moves to the side of the water inlet pipe 201 away from the control tooling 5, so that the clean water in the water storage tank 7 is sprayed out from the output end of the water injection pipe 211 along the water inlet pipe 201 and the working cylinder 214, and enters the installation hole of the diamond roller to cool the grinding rod 210 and the diamond roller;

[0058] When the extended end of the control cylinder 207 is retracted to the shortest, the control valve is closed, so that the clean water that enters the working cylinder 214 but is not discharged through the water injection pipe 211 pushes the one-way valve open and enters the leather bag 213. When the extended end of the cylinder 207 is in the shortest state, the second piston 202 slides to the side of the water inlet pipe 201 away from the flip frame 205, and one end of the grinding rod 210 reaches the cleaning position;

[0059] At this time, the adjusting roller 294 slides from the trapezoidal block 295 to the movable platform 208, so that the groove of the movable block 291 is close to the grinding rod 210, and the clean water injected into the working cylinder 214 from the water inlet pipe 201 will be sprayed onto the grinding rod 210 through the hose 292, so that the grinding chips stuck on the rough surface of the grinding rod 210 are efficiently cleaned. At the same time, the control valve is opened to allow the clean water in the bladder 213 to flush the grinding chips in the mounting hole of the diamond roller along the water injection pipe 211. This process can simultaneously clean the mounting hole of the diamond roller and the surface of the grinding rod 210, and ensure the water pressure when flushing the surface of the grinding rod 210.
