Description

Technical Field

[0001] This utility model relates to a special alloy cutting tool, specifically an alloy cutting tool with a cooling mechanism, belonging to the field of cutting tool technology. Background Technology

[0002] Special alloy cutting tools are tools designed for special machining needs, such as diamond tools, carbide end mills, and coated tools. They can be used in a variety of machining fields and are suitable for cutting various materials, such as high-hardness materials and cemented carbide.

[0003] In the prior art, such as the end mill with cooling function disclosed in CN215468358U, after adjusting the position of the air-cooling blades, the milling machine is started. The milling machine drives the cutter body to rotate at high speed. At the same time, the cutter body drives the air-cooling blades to rotate at high speed, thereby forming an airflow to cool the surface of the workpiece and the cutter body. Such end mills can cool themselves and the workpiece while processing, thus effectively avoiding high temperature ablation of the end mill or the workpiece.

[0004] However, in implementing the relevant technology, the following problems were found in the design of the above-mentioned end mill with cooling function: In the prior art, heat dissipation is achieved by improving gas flow through the cooperation of components such as cooling blades, but in actual use, it is mainly used for heat dissipation of the workpiece and the outside of the tool, which is insufficient for heat dissipation of the inside of the tool, resulting in poor heat dissipation effect. In view of this, an alloy tool with a cooling mechanism is provided to overcome the above defects. Utility Model Content

[0005] This invention provides an alloy cutting tool with a cooling mechanism to solve the technical problem that the cooling mechanism is mainly used for heat dissipation on the outside of the workpiece and the tool, but is insufficient for heat dissipation inside the tool, resulting in poor heat dissipation effect.

[0006] The present invention achieves the above objectives through the following technical solution: an alloy cutting tool with a cooling mechanism, comprising a cutting tool body, a connecting block fixed above the cutting tool body, a limiting block fixed at the top of the connecting block, a flow hole provided on the inner wall of the limiting block, and a cooling mechanism provided on the outside of the limiting block.

[0007] The cooling mechanism includes a fixed shell, which is fitted over the limiting block. A cooling plate is embedded in the outer wall of the fixed shell. A ventilation slot is provided on one side of the cooling plate on the outer wall of the fixed shell. A filter screen is embedded inside the ventilation slot. A connecting rod is fixed to the top of the fixed shell. A rechargeable battery is embedded in the outer wall of the connecting rod. A baffle is inserted into the ventilation slot. A rubber block is embedded in the outer wall of the baffle.

[0008] Preferably, the cooling mechanism further includes a rubber plug, which is inserted above the cooling fins on the outer wall of the fixed housing, and a collar is fitted below the cooling fins on the outer wall of the fixed housing.

[0009] Preferably, the rechargeable battery is electrically connected to the cooling element, and the cooling element is evenly distributed at equal intervals with respect to the outer wall of the fixed shell.

[0010] Preferably, the collar is threadedly connected to the fixed shell, and the fixed shell fits tightly against the baffle.

[0011] Preferably, a fixing block is fixed at the bottom of the fixing shell, and a limiting hole is opened on the inner wall of the fixing block corresponding to the position of the limiting block.

[0012] Preferably, an installation mechanism is provided below the collar. The installation mechanism includes an abutment block, which is sleeved on the outside of the fixing block. A locking block is fixed inside the abutment block, and a locking groove is provided on the outer wall of the fixing block at the position corresponding to the locking block.

[0013] Preferably, the installation mechanism further includes a slide groove, which is formed at the top of the contact block, and a sliding rod is rotatably connected inside the slide groove. A connecting ring is fixed at the top of the sliding rod, and a contact ring is fixed on the outer wall of the connecting block at the position corresponding to the contact block.

[0014] Preferably, the abutting block and the abutting ring are tightly fitted together, and the abutting block forms a sliding structure with the sliding rod through the sliding groove.

[0015] The beneficial effects of this utility model are:

[0016] 1) The limiting block of the connecting block above the tool body is inserted into the fixed shell and communicates with the fixed shell through the flow hole. When cutting, the rechargeable battery first provides power to the cooling chip to reduce the internal temperature of the fixed shell. Then, the machine tool power end drives the connecting rod to provide power. After the external air is filtered by the filter screen of the ventilation slot, it enters the fixed shell and is neutralized with the cold air. It is pushed by the external gas during rotation and enters the tool body through the flow hole. Finally, it is discharged through the bottom through hole to form a circulation, which can cool and dissipate heat inside the tool body and improve the heat dissipation effect. After the baffle drives the rubber block to block the ventilation slot, the position is limited by the collar to prevent it from falling off. The fixed shell is closed and the rubber plug is pulled out to inject coolant. Alternatively, the coolant can be injected through the power equipment that can supply coolant through the top of the connecting rod to dissipate heat. It can be used according to needs to improve the flexibility and comprehensiveness of use.

[0017] 2) When the limiting block is inserted into the fixed shell, the abutting block is sleeved on the outside of the connecting block and abuts against the outer wall of the abutting ring. At the same time, the locking block of the abutting block is inserted into the locking groove to lock in place, preventing loosening during cutting after connection. Meanwhile, the connecting ring is threaded to the fixed shell and is locked in place by the sliding rod and the sliding groove and the abutting ring through rotation. This allows the tool body and the fixed shell to be quickly assembled, while preventing loosening due to rotational force. The locking of the limiting block and the limiting hole of the fixed block further improves stability. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, as Figures 1 to 6As shown, this embodiment provides an alloy cutting tool with a cooling mechanism, including a cutting tool body 1, a connecting block 2 fixed above the cutting tool body 1, a limiting block 3 fixed at the top of the connecting block 2, a flow hole 4 formed in the inner wall of the limiting block 3, and a cooling mechanism 5 provided on the outside of the limiting block 3; the cooling mechanism 5 includes a fixing shell 501, which is sleeved on the outside of the limiting block 3, a cooling plate 504 embedded in the outer wall of the fixing shell 501, and a ventilation groove 502 formed on one side of the cooling plate 504 on the outer wall of the fixing shell 501, with a cooling plate 504 embedded inside the ventilation groove 502. A filter screen 503 is attached to the top of the fixed housing 501. A connecting rod 508 is fixed to the top of the fixed housing 501. A rechargeable battery 505 is embedded in the outer wall of the connecting rod 508. A baffle 506 is inserted into the interior of the ventilation slot 502. A rubber block 507 is embedded in the outer wall of the baffle 506. The cooling mechanism 5 also includes a rubber plug 509, which is inserted above the cooling chip 504 on the outer wall of the fixed housing 501. A collar 510 is fitted below the cooling chip 504 on the outer wall of the fixed housing 501. The rechargeable battery 505 is electrically connected to the cooling chip 504. The cooling chip 504 is positioned relative to the outer wall of the fixed housing 501. The walls are evenly distributed at equal intervals. The collar 510 is threadedly connected to the fixed shell 501, and the fixed shell 501 is tightly fitted to the baffle 506. The limiting block 3 of the connecting block 2 above the tool body 1 is inserted into the fixed shell 501 and communicates with the fixed shell 501 through the flow hole 4. When cutting, the rechargeable battery 505 first provides power to the cooling chip 504 to reduce the internal temperature of the fixed shell 501. Then, the power is provided by the connecting rod 508 driven by the machine tool power end. The external air is filtered by the filter screen 503 of the ventilation slot 502 and enters the fixed shell 501 to neutralize the cold air. Pushed by external gas during rotation, the gas enters the tool body 1 through the flow hole 4 and finally exits through the bottom through hole to form a circulation, which can cool and dissipate heat inside the tool body 1 and improve the heat dissipation effect. After the baffle 506 drives the rubber block 507 to block the ventilation groove 502, the position is adjusted by the collar 510 to limit it and prevent it from falling off. The fixed shell 501 is closed and the rubber plug 509 is pulled out to inject coolant. Alternatively, the coolant can be injected through the top of the connecting rod 508 via a power device that can supply coolant, and the coolant can dissipate heat. It can be used according to needs to improve the flexibility and comprehensiveness of use.

[0027] Example 2, in addition to all the technical features of Example 1, includes: a fixing block 6 fixed to the bottom of the fixing shell 501; a limiting hole 7 opened on the inner wall of the fixing block 6 corresponding to the position of the limiting block 3; an installation mechanism 8 provided below the collar 510; the installation mechanism 8 includes an abutment block 801, which is sleeved on the outside of the fixing block 6; a locking block 802 fixed inside the abutment block 801; a locking groove 803 opened on the outer wall of the fixing block 6 corresponding to the position of the locking block 802; the installation mechanism 8 also includes a sliding groove 804, which is opened at the top of the abutment block 801; a sliding rod 805 rotatably connected inside the sliding groove 804; a connecting ring 806 fixed to the top of the sliding rod 805; and the outer wall of the connecting block 2 fixed at the position corresponding to the position of the abutment block 801. There is an abutment ring 807, and the abutment block 801 fits tightly with the abutment ring 807. The abutment block 801 forms a sliding structure with the sliding rod 805 through the sliding groove 804. When the limiting block 3 is inserted into the fixed shell 501, the abutment block 801 is sleeved on the outside of the connecting block 2 and abuts against the outer wall of the abutment ring 807. At the same time, the locking block 802 opened on the abutment block 801 is inserted into the locking groove 803 for locking, so as to prevent loosening during cutting after connection. Meanwhile, the connecting ring 806 is threadedly connected to the fixed shell 501 and is locked by the sliding rod 805, the sliding groove 804 and the abutment ring 807 through rotation. This allows the tool body 1 and the fixed shell 501 to be quickly assembled, while preventing loosening due to rotational force. The locking of the limiting block 3 with the limiting hole 7 of the fixed block 6 further improves stability.

[0028] First, after the limiting block 3, which is fixed by the connecting block 2 on the top of the tool body 1, is inserted into the fixed shell 501, the abutment block 801 is fitted and the locking block 802 is aligned with the slot 803 opened in the fixed block 6, and the abutment ring 807 is engaged. The connecting ring 806 is engaged by sliding along the slide groove 804 through the sliding rod 805, thereby threadedly connecting with the fixed shell 501. This allows for quick assembly and disassembly of the tool body 1 and the fixed shell 501. The locking block 802 and the slot 803 improve stability and prevent rotation. At the same time, the limiting block 3 and the limiting hole 7 further improve the stability after connection, increasing the rotational force during torque and preventing slippage. The connecting rod 508 at the top of the fixed shell 501 is used to connect with the machine tool clamping end. When the tool body 1 is driven to perform cutting work, the fixed shell 501 rotates, allowing airflow to enter through the ventilation slot 502 and be filtered by the filter screen 503. Impurities enter the fixed housing 501 and are cooled by the cooling plate 504, thus neutralizing and cooling the gas. Driven by the airflow, the gas flows through the flow hole 4 into the tool body 1 and finally flows out from the bottom, forming a gas circulation to dissipate heat inside the tool body 1. At the same time, coolant can be introduced by injecting through a syringe by removing the rubber plug 509, or injected through the top of the connecting rod 508 via an adapter power device, providing different cooling methods to improve flexibility. The rechargeable battery 505 provides power to the cooling plate 504. When cooling is performed by coolant, the baffle 506 passes through the ventilation groove 502 and is sealed by the rubber block 507. The baffle 506 is limited by the collar 510 threaded to the fixed housing 501 to prevent it from detaching and to keep the fixed housing 501 sealed to prevent coolant leakage.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
