Description

Technical Field

[0001] The utility model relates to the technical field of cutting tools, in particular to a cutting tool for groove processing. Background Art

[0002] Groove processing is one of the common processing methods and is widely used in the production and manufacturing process of various products. The performance of cutting tools, as the core tools for groove processing, directly affects the processing efficiency and quality.

[0003] Traditional slotting cutting tools often need to be fixed with multiple sets of fasteners such as bolts or nuts. The disassembly and assembly process is cumbersome and time-consuming, which not only increases the labor intensity of workers, but also reduces production efficiency. In addition, during long-term continuous processing, due to the high-speed friction between the cutting tool and the workpiece, a large amount of heat will be generated, resulting in an increase in the blade temperature. High temperature will not only reduce the hardness and wear resistance of the tool, shorten the service life of the tool, but also affect the processing accuracy and surface quality. For this reason, we propose a cutting tool for slot processing. Utility Model Content

[0004] The purpose of the utility model is to provide a cutting tool for groove processing to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cutting tool for groove processing, comprising a transmission column, a card slot is provided on one side of the transmission column, a mounting plate is provided at the bottom of the transmission column, a card plate is installed on one side of the mounting plate, the card plate passes through the card slot, a limit assembly that can move up and down is installed on the surface of the transmission column, and a tool is installed on the bottom surface of the card plate;

[0006] The tool includes a tool rod, a tool head and two blades. The tool rod is welded to the bottom of the mounting plate, the tool head is welded to the lower end of the tool rod, the blade is welded to one side of the tool head, a plurality of heat sinks are welded on the surface of the blade, and two air guide holes are provided on the surface of the tool head.

[0007] Preferably, the size of the card plate matches the size of the card slot, and the card plate and the mounting plate are integrally formed.

[0008] Preferably, the limit assembly includes a limit plate and a threaded rod, the limit plate is slidably installed inside the mounting plate, one side of the limit plate is in contact with the outer side of the transmission column, the thread of the threaded rod passes through the limit plate, and one end of the threaded rod is rotatably installed on one side of the mounting plate.

[0009] Preferably, high frequency welding is adopted between the blade and the blade head.

[0010] Preferably, the heat sink is made of copper.

[0011] Preferably, the opening position of the air guide hole corresponds to the heat sink.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. When the cutting tool for groove processing is used, the transmission column drives the mounting plate, the tool rod and the tool head to rotate, thereby driving the blade to rotate for groove cutting. The high temperature generated by the friction of the blade can be transmitted to the heat sink, and during the rotation of the cutter head, the air flows through the air guide holes, and the air in the air guide holes takes away the high temperature on the surface of the heat sink, thereby cooling the blade and helping to ensure the service life of the tool.

[0014] 2. When disassembling the cutting tool used for groove processing, the threaded rod is rotated to drive the limit plate to move downward so that the top of the limit plate does not protrude from the mounting plate. At this time, the mounting plate is moved to one side as a whole so that the clamping plate is disengaged from the clamping slot, thereby completing the disassembly of the mounting plate and allowing the tool to be removed. When installing, the clamping plate is inserted into the clamping slot and the threaded rod is rotated in the opposite direction so that the limit plate moves upward and sticks to the outside of the transmission column, thereby fixing the position of the mounting plate, completing the installation of the tool and improving the efficiency of tool disassembly and assembly.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] Please refer to Figure 1-3As shown, the utility model provides a cutting tool for groove processing, including a transmission column 1, a card slot 2 is opened on one side of the transmission column 1, a mounting plate 3 is arranged at the bottom of the transmission column 1, a card plate 4 is installed on one side of the mounting plate 3, the card plate 4 passes through the card slot 2, a limit assembly that can move up and down is installed on the surface of the transmission column 1, and a tool is installed on the bottom surface of the card plate 4;

[0022] The tool includes a tool rod 7, a tool head 8 and two blades 10. The tool rod 7 is welded to the bottom of the mounting plate 3, the tool head 8 is welded to the lower end of the tool rod 7, the blade 10 is welded to one side of the tool head 8, a plurality of heat sinks 11 are welded on the surface of the blade 10, and two air guide holes 9 are provided on the surface of the tool head 8.

[0023] Specifically, when the cutter rotates, air passes through the air guide holes 9 and blows toward the heat sink 11 . The heat sink 11 can conduct the heat generated by the blade 10 , thereby effectively dissipating the heat from the blade 10 .

[0024] The size of the card plate 4 matches the size of the card slot 2 , and the card plate 4 and the mounting plate 3 are integrally formed. After the card plate 4 is inserted into the card slot 2 , the mounting plate 3 and the card plate 4 cannot move up and down, forward and backward.

[0025] Among them: the limit assembly includes a limit plate 5 and a threaded rod 6, the limit plate 5 is slidably installed inside the mounting plate 3, one side of the limit plate 5 is in contact with the outer side of the transmission column 1, the threaded rod 6 threads penetrate the limit plate 5, one end of the threaded rod 6 is rotatably installed on one side of the mounting plate 3, and rotating the threaded rod 6 can drive the limit plate 5 to move up and down.

[0026] Wherein: high frequency welding is adopted between the blade 10 and the cutter head 8 to ensure the connection strength between the cutter head 8 and the blade 10 .

[0027] Wherein: the heat sink 11 is made of copper, and the heat sink 11 made of copper has a better heat dissipation effect.

[0028] The opening position of the air guide hole 9 corresponds to the heat sink 11 . When the cutter head 8 rotates, the air passing through the air guide hole 9 can blow toward the heat sink 11 , thereby improving the heat dissipation efficiency of the heat sink 11 .

[0029] Working principle: The utility model is a cutting tool for slot processing. When in use, the transmission column 1 drives the mounting plate 3, the tool rod 7, and the tool head 8 to rotate, thereby driving the blade 10 to rotate for slot cutting. The high temperature generated by the friction of the blade 10 can be transmitted to the heat sink 11, and during the rotation of the tool head 8, the air flows through the air guide hole 9, and the air in the air guide hole 9 takes away the high temperature on the surface of the heat sink 11, thereby playing a role in cooling the blade 10. Multiple heat sinks 11 block one side of the air guide hole 9, which can prevent larger cutting waste from entering the air guide hole 9 and clogging the air guide hole 9;

[0030] During disassembly, the threaded rod 6 is rotated to drive the limit plate 5 to move downward so that the top of the limit plate 5 does not protrude from the mounting plate 3. At this time, the mounting plate 3 is moved to one side as a whole so that the clamping plate 4 is disengaged from the clamping slot 2, thereby completing the disassembly of the mounting plate 3 and allowing the tool to be removed. During installation, the clamping plate 4 is inserted into the clamping slot 2 and the threaded rod 6 is rotated in the opposite direction so that the limit plate 5 moves upward and sticks to the outside of the transmission column 1, thereby fixing the position of the mounting plate 3 and completing the installation of the tool.
