Description

Technical Field

[0002] In the field of metal processing, the precision and quality of the cutting edge of the ring insert directly affect the cutting efficiency and machining quality. Therefore, the cutting edge of the ring insert is ground during processing to improve the cutting quality in later use.

[0003] The machining of ring-shaped cutting blades often involves manual grinding or simple mechanical grinding.

High temperatures can easily cause changes in the properties of the cutting edge material, such as edge burns, increased surface roughness, or thermal cracks, which will reduce the machining quality of the cutting edge. In addition, flying debris can easily cut the operator's skin or eyes, causing workplace accidents and reducing machining safety.

[0026] Example 1

[0027] like Figure 1-5 As shown, this is the first embodiment of the present invention, which provides a ring-shaped blade edge processing device, including...

[0028] The processing unit 100 includes a worktable 110 and a grinding assembly 130, a bearing assembly 140 disposed at the front end of the inner cavity of the worktable 110 and used to limit and support the cutting blade, an adjustment mechanism 120 disposed at the rear end of the inner cavity of the worktable 110 and used to adjust the position of the grinding assembly 130, and a through groove 150 opened at the front end of the bottom of the inner cavity of the worktable 110 and used to transport water and debris.

[0029] The cooling unit 200 includes a cold water tank 210, a cooling component 220 disposed on one side of the cold water tank 210, a water pump 230 fixedly connected to one side of the inner cavity of the cold water tank 210, a hose 240 connected to the outlet of the water pump 230, a bamboo tube 250 disposed on one side of the regulating mechanism 120 and connected to the hose 240, and a filter frame 260 fixedly connected to the front end of the inner cavity of the cold water tank 210 and used to intercept waste debris in the water.

[0030] The cooling component 220 includes a connecting cover 221, a semiconductor cooling chip 222 disposed in the inner cavity of the connecting cover 221 and extending to the inner cavity of the cold water tank 210 on one side, and a cooling fan 223 disposed on one side of the connecting cover 221 for accelerating the heat dissipation and cooling of the semiconductor cooling chip 222.

[0031] like Figure 1-5As shown, the processing unit 100 integrates a worktable 110, a grinding assembly 130, a support assembly 140, and an adjustment mechanism 120, forming a complete processing system. The worktable 110 provides a stable working platform, while the support assembly 140 limits and supports the cutting blade, ensuring stability during subsequent processing.

During grinding, cooling water is stored in a cold water tank 210, and a water pump 230 delivers cooling water to the grinding area via a hose 240 and a bamboo-joint tube 250 to cool the cutting blade, preventing overheating and wear. Simultaneously, the sprayed water... Cold water can adsorb the generated debris, causing it to mix with the water without splashing. The debris then enters the cold water tank 210 through the channel 150. The filter frame 260 effectively intercepts the debris in the water, facilitating subsequent unified processing. During the cooling process, a combination of a semiconductor cooling chip 222 and a cooling fan 223 is used. The semiconductor cooling chip 222 is a TEC1-12706 model.

This meets the high precision and high efficiency requirements of ring blade cutting edge processing, improving production efficiency and product quality.

[0032] Example 2

[0033] Reference Figure 1-3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] In this embodiment, the adjustment mechanism 120 includes a movable frame 121, a first screw 122 threaded to the rear of the worktable 110 and movably connected to the movable frame 121 at one end via a bearing, a second screw 123 movably connected to the top of the movable frame 121 via a bearing, a connecting sleeve 124 threaded to the surface of the second screw 123, and a connecting frame 125 fixedly connected to the back of the connecting sleeve 124 and used to drive the grinding assembly 130 to move.

[0035] The bottom of the inner cavity of the workbench 110 is fixedly connected to the limiting seat 128. The bottom of the movable frame 121 extends into the inner cavity of the limiting seat 128 and is slidably connected to the inner cavity of the limiting seat 128. The back of the connecting frame 125 is fixedly connected to the limiting block 126. The back of the inner cavity of the movable frame 121 is provided with a limiting groove 127. One end of the limiting block 126 extends into the inner cavity of the limiting groove 127 and is slidably connected to the inner cavity of the limiting groove 127.

[0036] The grinding assembly 130 includes a geared motor 131 fixedly connected to the bottom of the inner cavity of the connecting frame 125, a grinding wheel 132 drivenly connected to the output shaft of the geared motor 131, and an intercepting cover 133 sleeved on the surface of the grinding wheel 132 and fixedly connected to the bottom of the connecting frame 125 at its top.

[0037] like Figure 1-3 As shown, when the horizontal position of the grinding assembly 130 needs to be adjusted, the first screw 122 is rotated. Since the first screw 122 is threadedly connected to the worktable 110, rotating the first screw 122 will drive the movable frame 121 and the second screw 123, connecting sleeve 124, connecting frame 125, and grinding assembly 130 connected to it to move horizontally. When the vertical position of the grinding assembly 130 needs to be adjusted, the second screw 123 is rotated. Since the second screw 123 is threadedly connected to the connecting sleeve 124, rotating the second screw 123 will drive the connecting sleeve 124 and grinding assembly 130 to move vertically, thereby achieving... During adjustment, the movable frame 121 is slidably connected to the inner cavity of the limiting seat 128 through its bottom, ensuring stable movement of the movable frame 121 in the horizontal direction. At the same time, the limiting block 126 on the back of the connecting frame 125 is slidably connected to the limiting groove 127 in the inner cavity of the movable frame 121, ensuring the stability of the connecting frame 125 in the vertical direction. The reduction motor 131 provides stable power output to the grinding wheel 132, causing the grinding wheel 132 to rotate to grind the blade edge. During the grinding process, the intercepting cover 133 is fitted on the surface of the grinding wheel 132, which can initially prevent the flying of debris generated during the grinding process and improve the processing safety.

[0038] Example 3

[0039] Reference Figure 1 and 4 5 is the third embodiment of this utility model, which is based on the first two embodiments.

[0040] In this embodiment, the support assembly 140 includes a placement seat 141 fixedly connected to the bottom of the inner cavity of the workbench 110 and used to support the blade, a third screw 142 fixedly connected to the top of the placement seat 141, a nut 143 threadedly connected to the surface of the third screw 142, and a washer 144 fixedly connected to the bottom of the nut 143. The bottom of the nut 143 is in contact with the blade.

[0041] The through groove 150 is connected to the inner cavity of the cold water tank 210. The top and bottom of the connecting cover 221 are provided with ventilation grooves 224. The front of the cold water tank 210 is connected to a closed door 211 by a hinge. A sealing strip is fixedly connected to the back of the closed door 211 and the sealing strip is in contact with the cold water tank 210. The lower end of the front of the cold water tank 210 is connected to a drain pipe 212.

[0042] like Figure 1 and 4 As shown in Figure 5, by fitting the annular blade onto the surface of the third screw 142 and placing it on top of the mounting base 141, and considering that the annular blade has a connecting through hole on its top for easy installation with the cutting equipment, the blade can be initially positioned by fitting it onto the surface of the third screw 142 through the through hole. Since the size of the third screw 142 is smaller than the through hole, it easily accommodates the through hole on the blade, thus achieving initial positioning of the annular blade after fitting. Then, personnel can rotate the nut 143. Because the nut 143 is threadedly connected to the third screw 142, rotation will gradually drive the blade... The gasket 144 contacts the blade downwards, thereby supporting and positioning the blade for easy subsequent processing. It is connected to the inner cavity of the worktable 110 through the through groove 150 for the transmission of water and debris, facilitating the subsequent handling of water and debris. The ventilation slot 224 facilitates air circulation inside the connecting cover 221, providing a good heat dissipation environment and ensuring the continuity and stability of the cooling effect. The sealing door 211 and sealing strip ensure the airtightness of the cold water tank 210, and the opening of the sealing door 211 facilitates the removal and handling of debris intercepted on the filter frame 260. The drain pipe 212 facilitates the discharge of cooling water.

[0043] In use, firstly, an appropriate amount of cooling water is added to the cold water tank 210 through the through groove 150. Next, the annular blade is fitted onto the surface of the third screw 142 and positioned at the top of the placement seat 141, achieving initial positioning of the annular blade. Then, by rotating the nut 143, the nut 143 gradually drives the washer 144 downwards to contact the blade, thus supporting and positioning the blade for later processing. Afterwards, the operator can rotate the first screw 122 and the second screw 123 in the adjusting mechanism 120 to move the movable frame 121 and the connecting frame 125, thereby adjusting the position of the grinding assembly 130 to align it with the blade cutting edge. After adjustment, the reduction motor 131 is started to drive the grinding wheel 132 to rotate, beginning the grinding of the blade. Simultaneously, the interceptor cover 133 initially intercepts flying debris, and the water pump 230 is started, supplying water... Pump 230 draws cooling water from cold water tank 210 and delivers it to the grinding area through hose 240 and bamboo tube 250 to cool the grinding wheel 132 and the cutting tool, preventing overheating and wear. The sprayed cold water can also absorb the generated debris, causing it to mix with the water without splashing. The debris then enters the cold water tank 210 through the channel 150. The filter frame 260 effectively intercepts debris in the water, facilitating subsequent unified processing. During the processing, the cooling component 220 works continuously. The semiconductor cooling chip 222 absorbs heat from the water in the cold water tank 210 using the Peltier effect and dissipates the heat through the cooling fan 223, achieving continuous cooling of the cooling water in the cold water tank 210. This ensures the continuity and stability of the cooling effect, thereby meeting the high precision and high efficiency requirements of ring cutting tool edge processing and improving production efficiency and product quality.
