DETAILED DESCRIPTION
[0025] Please refer to Figs. 1-3 The utility model provides a technical scheme: a gear machining cooling device, including heat dissipation plate 1 and copper pipe 2, copper pipe 2 is provided with multiple and different diameters, makes copper pipe 2 present the concentric circle's distribution mode and is embedded in heat dissipation plate 1, makes copper pipe 2 at the outermost circle both sides be connected with water inlet pipe 22 and water outlet pipe 23 respectively, still installs electromagnetic valve 221 with the intercommunication of water inlet pipe 22 on it, electromagnetic valve 221 can control the opening degree and on-off state of water inlet pipe 22, makes the cooling water of cool water or water cooling system pass through water inlet pipe 22 and enter copper pipe 2 at the outermost circle, then flows to the direction of water outlet pipe 23 of the other side and discharges.
[0026] In order to realize the purpose that copper pipe 2 at the inner circle also flows through cool water or cooling water, makes copper pipe 2 between the alignment position of water inlet pipe 22 and water outlet pipe 23 intercommunicate through connecting pipe 21, and then cool water and cooling water can also flow to the direction of water outlet pipe 23 through all copper pipes 2, annular first heat-conducting silica gel 11 is fixed on the upper surface of heat dissipation plate 1, when using, can make the upper surface of heat dissipation plate 1 through the first heat-conducting silica gel 11 of outer ring and stick in the lower surface of gear cutter of cutting gear, since the gear cutter is cut by the cutting edge of outer ring, therefore the heat of gear cutter mainly distributes in the outer ring, can be better heat-conducted through the first heat-conducting silica gel 11 of ring shape and make the heat be absorbed and taken away by cool water or cooling water in copper pipe 2, realize the purpose of good heat dissipation of gear cutter, the gear cutter no longer relies on the heat dissipation from cutting oil, the cutting oil only needs to satisfy the lubrication purpose when cutting at this time, therefore can make the cutting fluid be sprayed to the gear workpiece at relatively low speed and reduce waste and recovery processing cost.
[0027] In order to realize the quick fixing and taking down of the heat dissipation plate 1, and facilitate the purpose of locking the heat dissipation plate 1 again after the gear cutter is replaced, a plurality of magnets 3 are embedded and fixed in the inner circle of the first heat-conducting silica gel 11, and the heat dissipation plate 1 is attached to the lower surface of the gear cutter by the magnetic attraction of the magnets 3, which facilitates the taking down of the heat dissipation plate 1 and the re-attachment of the heat dissipation plate 1 to the bottom surface of the new gear cutter. The bottom surface of the heat dissipation plate 1 is fixed with a handle 12, which is located at the middle position of the bottom of the heat dissipation plate 1. The outer circle of the handle 12 is sleeved and fixed with a rubber sleeve 121, and the inner circle of the rubber sleeve 121 is tightly attached to the outer surface of the handle 12. The rubber sleeve 121 can be used to hold the handle 12 comfortably and prevent slipping, and the heat dissipation plate 1 can be held and pulled to be taken down and re-attached.
[0028] A patch type temperature sensor 4 is fixed at the middle position of the surface of the heat dissipation plate 1, and the patch type temperature sensor 4 is located at the middle position of the magnet 3. The surface of the patch type temperature sensor 4 is provided with a second heat-conducting silica gel 41. When the heat dissipation plate 1 is attached to the bottom of the gear cutter, the patch type temperature sensor 4 is in contact with the surface of the gear cutter through the second heat-conducting silica gel 41. The patch type temperature sensor 4 monitors the temperature at the middle position of the gear cutter. Since the heating part of the gear cutter is at the outer circle, the temperature at the middle position of the gear cutter will be lower than that at the outer circle. Therefore, the monitoring set temperature threshold needs to be lower. By monitoring whether the temperature at the middle position of the gear cutter exceeds the set threshold, it can be determined whether the temperature of the outer circle of the gear cutter is too high.
[0029] In use, the water inlet pipe 22 is connected to the cool water supply pipe, and the water outlet pipe 23 is directly connected to the drain pipe, or the water inlet pipe 22 and the water outlet pipe 23 are respectively connected to the cooling water supply pipe and the return pipe of the water cooling system. The device is held by hand through the handle 12, and then the upper surface of the heat dissipation plate 1 is attached to the lower surface of the gear cutter. Due to the magnetic attraction of the magnet 3 to the bottom surface of the gear cutter, the upper surface of the heat dissipation plate 1 is tightly attached to the lower surface of the gear cutter through the first heat-conducting silica gel 11, and the patch type temperature sensor 4 is also attached to the lower surface of the gear cutter through the second heat-conducting silica gel 41. The electromagnetic valve 221 and the patch type temperature sensor 4 are connected to the industrial computer. When the gear cutter is driven to move up and down for gear cutting, the electromagnetic valve 221 is opened at the same time, so that cool water or cooling water flows into the copper pipe 2 from the water inlet pipe 22, flows from both sides of the connecting pipe 21 to the other end, and finally flows out from the water outlet pipe 23. In this process, the gear cutter can be cooled by the heat dissipation plate 1, and the gear cutter no longer relies on the heat dissipation from the cutting oil. The cutting oil only needs to meet the lubrication purpose during cutting at this time, so the cutting fluid can be sprayed on the gear workpiece at a relatively low speed to reduce waste and recycling cost.
