Description

Technical Field

[0001] The utility model relates to the technical field of machine tool cutters, in particular to a machine tool cutter which is convenient for heat dissipation. Background Art

[0002] Machine tool tools are tools used in mechanical manufacturing for cutting, grinding and other operations on workpieces. Since the tools used in mechanical manufacturing basically act on metal materials, the term tool is generally understood to be a metal tool. When currently used, the existing machine tool tools mostly complete the processing work by high-speed rotation of the tool itself or the workpiece. Therefore, during use, the tool will generate a lot of heat, and overheating will affect the work of the tool.

[0003] For example, a machine tool tool with a heat dissipation structure disclosed in publication number CN220112877U, the device arranges coolant inside the tool head to absorb heat from the tool head when the tool head rotates at high speed, and cooperates with the function of the refrigeration plate to cool the coolant that vaporizes after absorbing heat, thereby maintaining the continuous and effective heat absorption operation of the coolant and achieving a continuous cooling and heat dissipation effect on the tool.

[0004] However, the heat dissipation structure can only add too little coolant when in use, and the flow rate of the coolant cannot be adjusted to a certain extent. The heat dissipation structure can only set a part of the coolant inside the cutter head for cooling. This results in the need to frequently add coolant during long-term tool processing work, thereby reducing the use effect of the device. In view of this, we propose a machine tool tool that is easy to dissipate heat. Utility Model Content

[0023] Specifically, the heat dissipation structure 3 of the technical solution of the utility model includes: a hollow shaft 31, a heat dissipation cylinder 32, a one-way valve 33, a liquid pipe 34, a water supply valve 35, a valve stem 36, a liquid outlet 37, a motor 38, a driving wheel 39, and a driven wheel 310.

[0024] In one embodiment of the utility model, a heat dissipation structure 3 is provided to facilitate long-term cooling of the surface of the cutter head 1, a top cover 2 is provided to place multiple groups of devices, a water inlet pipe 5 is provided to add coolant to the inside of the heat dissipation tube 32, a liquid passage pipe 34 is provided to transport liquid, and a water supply valve 35 is provided on the surface of the liquid passage pipe 34 to change the speed of liquid transportation, and the size of the water flow is changed by rotating the valve stem 36. When in use, the user can first rotate the valve stem 36 to close the water supply valve 35, and then add cooling water to the water inlet pipe 5 on the side wall of the heat dissipation tube 32, and then rotate the valve stem 36 until the water flow can drip more slowly.

[0025] Then the device can be started to carry out processing work. During the processing work, the coolant inside the heat dissipation tube 32 is passed into the hollow shaft 31, and then the coolant will move along the hollow shaft 31 and enter the inside of the cutter head 1 through the liquid port, and the liquid will move outward through several groups of liquid outlets 37.

[0026] By setting up the adjustment structure 4, it is convenient to control the liquid inlet speed of the liquid pipe 34 according to the different temperatures of the heat transmitted by the cutter head 1. When the cutter head 1 rotates, the cutter head 1 will generate a lot of heat due to the friction with the workpiece. The heat will be transferred to the inside of the cutter head 1 along the cutter head 1. At this time, the hot air will move upward along the liquid port and be discharged through the vent 49. At this time, the hot air will move through the vent pipe 48 and contact the expansion block 42. The expansion block 42 is made of silicone rubber, which is easy to expand due to heat. Other materials with higher expansion coefficients can also be used to make the expansion The block 42 expands upward, and after the expansion block 42 expands, it will drive the slide plate 43 at its upper end to move. The movement of the slide plate 43 causes the tooth plate 44 at its upper end to move upward, driving the adjusting gear 45 to rotate in the direction of increasing the opening and closing degree of the water supply valve 35, thereby accelerating the liquid flow speed inside the liquid pipe 34, thereby improving the use effect of the device, and after the temperature drops, the expansion block 42 no longer expands and moves downward, thereby causing the driving adjusting gear 45 to rotate in the direction of reducing the opening and closing degree of the water supply valve 35, thereby saving cooling water and further improving the use effect of the device.

[0028] During operation, first rotate the valve stem 36 to close the water supply valve 35, then add cooling water to the water inlet pipe 5 on the side wall of the heat dissipation tube 32, then rotate the valve stem 36 until the water flow can drip more slowly, and then start the device to perform processing work. At this time, the coolant inside the heat dissipation tube 32 is passed into the hollow shaft 31, and then these coolants will move along the hollow shaft 31 and enter the inside of the cutter head 1 through the liquid through hole, and these liquids will move outward through several groups of liquid outlets 37. The liquid outlet 37 is in a connected state with the liquid through hole, so that the coolant can directly act on the surface and inside of the cutter head 1. When the cutter head 1 rotates, the cutter head 1 will generate a lot of heat due to the friction with the workpiece, and the heat will be transferred along the cutter head 1 to the inside of the cutter head 1. At this time, the hot air It will move upward along the liquid passage and be discharged through the vent 49. At this time, the hot air will move through the vent pipe 48 and contact the expansion block 42, so that the expansion block 42 will expand upward. After the expansion block 42 expands, it will drive the slide plate 43 at its upper end to move.
