Technical Field
[0001] The utility model relates to a grinding machine tool, in particular to a heat dissipation structure of the grinding machine tool. Background Art
[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, while a few use other grinding tools such as oilstones and abrasive belts and free abrasives for processing. The grinder tool is an important component of the grinder.
[0003] In the prior art, when the existing grinding machine tool is in use, the grinding machine tool is in contact with the workpiece for a long time when processing the workpiece, resulting in poor heat dissipation of the tool, which reduces the service life of the tool. When dissipating the heat of the tool, a fan is generally used to blow air to dissipate the heat of the tool, or the tool is sprayed to dissipate the heat and only one side of the tool can be sprayed, but the other side cannot be sprayed, resulting in low heat dissipation efficiency and short service life. Moreover, when spraying the heat, impurities on the workpiece are easy to enter the coolant, which makes it inconvenient to recycle the coolant. Now there is an urgent need for a heat dissipation structure for the grinding machine tool to solve the above problems. Utility Model Content

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.
[0026] like Figure 1 As shown, the utility model provides a technical solution: a heat dissipation structure of a grinding tool, comprising:
[0027] A base 1 is provided with a vertical plate 2 on the top of the base 1, a hydraulic cylinder 3 is provided on the side wall of the vertical plate 2, a mounting seat 6 is provided on the telescopic shaft of the hydraulic cylinder 3, a motor 22 is provided inside the mounting seat 6, a blade 14 is provided on the output shaft of the motor 22, a lifting table 15 is provided on the top of the base 1, and an avoidance groove 151 for avoiding the blade 14 is provided on the top of the workbench 15;
[0028] A support plate 7 is provided on the top of the mounting seat 6, and a heat sink 12 is provided on the side wall of the support plate 7, which is placed just above the blade 14 and is used to spray water on both sides of the blade 14. A U-shaped tube 11 is provided on the top of the heat sink 12, and a connecting pipe 10 is provided at the top center of the U-shaped tube 11. A water pump 9 is provided on the top of the connecting pipe 10, and a water delivery pipe 4 is provided on the water pump 9. The design places the workpiece at a suitable position on the workbench 15, and then drives the mounting seat 6 to move horizontally, so that the blade 14 moves to a suitable position, so that the electric The machine 22 drives the blade 14 to rotate, and then the workbench 15 is raised and lowered so that the workpiece is close to the blade 14, and the blade 14 is retracted into the avoidance groove 151, thereby completing the processing of the workpiece. While the blade 14 is processing the workpiece, the water pump 9 is operated to extract the coolant through the water pipe 4, and the coolant flows through the connecting pipe 10 and the U-shaped pipe 11 into the heat sink 12. The coolant finally flows out from the heat sink 12 to spray cooling on both sides of the blade 14 at the same time, thereby accelerating the heat dissipation speed of the blade 14 and improving the heat dissipation efficiency.
[0029] Reference Figure 1 A connecting plate 8 connected to a water pump 9 is provided on the top of the support plate 7. The water pipe 4 passes through the side wall of the connecting plate 8. The water pipe 4 is a metal hose. This design facilitates the support and connection of the water pump 9 by using the connecting plate 8, so that the water pipe 4 is a metal hose, thereby preventing the water pipe 4 from bending and affecting the flow of liquid.
[0030] Reference Figure 1 , Figure 3 and Figure 4 A pair of liquid separation chambers 121 are symmetrically provided inside the heat sink 12, and the pair of liquid separation chambers 121 are respectively connected to the two outlet ends of the U-shaped tube 11. A plurality of nozzles 13 are provided at positions corresponding to the pair of liquid separation chambers 121 at the bottom of the heat sink 12. This design uses a pair of liquid separation chambers 121 to be respectively connected to the two outlet ends of the U-shaped tube 11, so that the coolant enters the pair of liquid separation chambers 121 and is sprayed out from the nozzles 13 at the bottom thereof, thereby spraying water to cool both sides of the blade 14. The nozzles 13 on the pair of liquid separation chambers 121 are placed on both sides of the blade 14, thereby improving the accuracy of spraying and cooling both sides of the blade 14 at the same time.
[0031] Reference Figure 1 and Figure 2A liquid storage tank 101 for storing coolant is provided inside the base 1, and the water pipe 4 is connected to the liquid storage tank 101. A pair of water baffles 24 connected to the vertical plate 2 and used to shield the liquid sprayed from the heat sink 12 to both sides of the blade 14 are symmetrically arranged on the top of the base 1. A plurality of lower liquid holes 17 connected to the liquid storage tank 101 are provided on the top of the base 1, and a filter screen 16 for shielding the lower liquid holes 17 is provided on the top of the base 1. This design shields the liquid sprayed to both sides of the blade 14 by using the water baffle 24, so that the liquid flows back to the inside of the liquid storage tank 101 along the plurality of lower liquid holes 17, and filters the impurities under the action of the filter screen 16 to prevent the impurities from flowing back into the coolant in the liquid storage tank 101. Finally, the coolant is recycled through the water pump 9 and the water pipe 4, which facilitates the recycling of the coolant.
[0032] Reference Figure 1 and Figure 5 A pair of guide columns 5 arranged on both sides of the hydraulic cylinder 3 are symmetrically arranged on one side of the mounting seat 6 close to the vertical plate 2, and the guide columns 5 penetrate the vertical plate 2. This design uses the guide columns 5 to penetrate the vertical plate 2, so that the guide columns 5 move along the vertical plate 2. A through hole can be opened on the vertical plate 2 to match the guide columns 5, so that the guide columns 5 are used to limit and guide the mounting seat 6, thereby improving the stability of the lateral movement of the mounting seat 6. A liquid outlet pipe 18 connected to the liquid storage tank 101 is provided on the side wall of the base 1, and a valve 181 is provided on the side wall of the liquid outlet pipe 18. This design facilitates the discharge of coolant by using the liquid outlet pipe 18 and the valve 181. Coolant can be added to the liquid storage tank 101 by connecting the liquid outlet pipe 18 to the external pump body, thereby facilitating the replacement operation of the coolant.
[0033] Reference Figure 1 and Figure 6 A buzzer 21 and a PLC controller 19 are provided on the side wall of the base 1. A liquid level sensor 20 inserted into the liquid storage tank 101 is provided on the side wall of the base 1. The buzzer 21 and the liquid level sensor 20 are respectively connected to the PLC controller 19. The design detects the height of the coolant by using the liquid level sensor 20. When it exceeds the set value, a signal is sent to the PLC controller 19 to make the buzzer 21 work and issue an alarm, thereby avoiding overflow of the liquid storage tank 101. A temperature sensor can be provided here. When it is detected that the coolant inside the liquid storage tank 101 is higher than the set temperature value, a signal is sent to the PLC controller 19 to make the buzzer 21 work and issue an alarm to remind to replace the coolant.
[0034] Reference Figure 2 An electric push rod 23 for pushing the workbench 15 up and down is arranged inside the base 1. This design facilitates pushing the workbench 15 up and down by using the electric push rod 23. The electric push rod 23 can be replaced with a hydraulic cylinder 3. A sealing ring is arranged at the connection between the telescopic shaft of the electric push rod 23 and the base 1.
[0035] Reference Figure 1-Figure 6 As an embodiment of the utility model: when the blade 14 needs to be cooled during use, the workpiece is placed at a suitable position on the workbench 15, and then the hydraulic cylinder 3 is operated to drive the mounting seat 6 to move horizontally, so that the blade 14 is moved to a suitable position, the motor 22 is operated to drive the blade 14 to rotate, and then the electric push rod 23 is operated to push the workbench 15 to be lifted and lowered so that the workpiece is close to the blade 14, and the blade 14 is retracted into the avoidance groove 151, thereby completing the processing of the workpiece. While the blade 14 is processing the workpiece, the water pump 9 is operated to extract the coolant through the water pipe 4, and the coolant flows through the connecting pipe 10 and the U-shaped pipe 11 into a pair of liquid separation chambers 121 inside the heat dissipation plate 12, and is sprayed from the nozzles 13 corresponding to the bottom of the pair of liquid separation chambers 121 to spray liquid on both sides of the blade 14 for cooling, thereby accelerating the heat dissipation speed of the blade 14 and improving the heat dissipation efficiency.
[0036] Under the action of the water baffle 24, the liquid sprayed on both sides of the blade 14 is blocked, so that the liquid flows back to the inside of the liquid storage tank 101 along the multiple lower liquid holes 17, and the impurities are filtered under the action of the filter screen 16 to prevent the impurities from flowing back into the coolant in the liquid storage tank 101. Finally, the coolant is recycled through the water pump 9 and the water pipe 4, which facilitates the recycling of the coolant and improves the practicality of the utility model.
