Description

Technical Field

[0001] The present application relates to the technical field of side milling cutters, and in particular to a side milling combination cutter. Background Art

[0002] In machining, a milling cutter is a rotating tool used to process workpieces. It is mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces, etc. Side milling cutter is a type of milling cutter.

[0003] During the tool processing, tool cooling is crucial, and during cooling, coolant needs to be sprayed through the water outlet for cooling. The existing water outlet holes are directly processed on the cutter head body, which requires drilling on the cutter head body. The diameter of the side milling cutter is relatively large, so the processing depth of the water outlet hole is very deep. At the same time, in order to enhance the impact force of the coolant, the diameter of the water outlet hole is relatively small, and the aperture of the water outlet hole is 3-4MM. This places high requirements on the drill bit and makes processing very difficult. Utility Model Content

[0004] In order to improve the machining convenience of the tool and also improve the cooling effect of the tool, the present application provides a side milling combination tool.

[0005] The present application provides a side milling combined cutter, which adopts the following technical solution:

[0006] A side milling combination cutter comprises a tool handle and a cutter disc body arranged on the tool handle, wherein a channel for cooling liquid to pass through is formed in the tool handle, a water hole connected to the channel is formed on the outer wall of the tool handle, a water spray member is sleeved on the tool handle and abuts against the tool handle and the cutter disc body, a water storage chamber connected to the water hole is formed between the water spray member and the tool handle, and a plurality of water spray holes connected to the water storage chamber and having a smaller aperture than the aperture of the water hole are formed on the water spray member and are used for spraying cooling liquid toward the cutter disc body.

[0007] By adopting the above technical solution, the water spray piece is put on the tool handle and abuts against the tool handle, and then the cutter head body is installed on the tool handle for fixing, and the cutter head body abuts against the water spray piece for positioning, so that the coolant can pass through the channel, the water hole, and the water storage cavity in sequence, and finally the coolant is sprayed to the cutter head body through multiple water spray holes for cooling, thereby realizing cooling of the cutter head body and the tool handle, and reducing the probability of the tool handle temperature being too high;

[0008] During processing, the channel and the water hole are processed when the tool handle is processed, and the coolant sprayed from the multiple water holes flows out through the water holes. Therefore, the aperture of the water hole is much larger than the aperture of the water hole. In the present application, the sum of the length of the water hole, the thickness of the water storage chamber and the length of the water hole is the same as the length of the water hole in the prior art, thereby shortening the length of the drill bit when processing the water hole. At the same time, the aperture of the hole is increased by the water hole, thereby greatly reducing the processing difficulty, and making the water hole processing able to better realize the cooling of the cutter disc body, thereby improving the cooling effect of the cutter disc body.

[0009] Optionally, the water spray hole passes through one end of the water spray member close to the cutter disc body.

[0010] By adopting the above technical scheme, the water spray hole can be closer to the cutter head body, so that the coolant can directly impact the cutter head body and the product processing part, that is, it can impact the debris, making it easier to discharge the debris, thereby further improving the cooling effect of the cutter head body and the processing quality of the product. Moreover, the water spray hole is connected with the water spray part, so not only a drill bit but also a milling cutter can be used to process the water spray hole, so that the original hole length as the processing depth is transformed into the hole radius as the processing depth, which greatly reduces the processing depth, thereby further reducing the difficulty of processing and improving the convenience of tool processing.

[0011] Optionally, two cutter disc bodies are arranged at intervals, both ends of the water spray member are positioned against the two cutter disc bodies, two groups of water spray holes are arranged in one-to-one correspondence with the two cutter disc bodies, and the two groups of water spray holes are staggered.

[0012] By adopting the above technical solution, the two cutter disc bodies cooperate to process the product, thereby improving the processing quality and efficiency, and the two groups of water spray holes cool the two cutter disc bodies accordingly, thereby improving the cooling effect of the cutter disc bodies.

[0013] Optionally, the tool handle is provided with a key block which is plugged into the tool disc body for positioning.

[0014] By adopting the above technical solution, the key block is plugged into the cutter body, so that the rotation of the handle drives the cutter body to rotate at the same time, reducing the probability of relative rotation between the cutter body and the handle, and the key block is used to position the cutter body so that the cutter body can be aligned with the water spray hole, thereby further improving the cooling effect on the cutter body.

[0015] Optionally, a positioning member is provided on the knife handle for positioning the water spray member and aligning the water spray hole with the knife tip of the cutter disc.

[0016] By adopting the above technical solution, the positioning part is used to position the water spray part so that the water spray hole can be aligned with the cutter disc body. At the same time, the positioning part enables the water spray part and the tool handle to rotate together, so that after the tool rotates, the water spray hole can continue to be aligned with the tip of the cutter disc body, thereby further improving the cooling effect on the cutter disc body.

[0017] Optionally, a positioning groove is provided on the water spraying member, and the positioning member is a positioning block which is arranged on the knife handle and is plugged into and matched with the positioning groove.

[0018] By adopting the above technical solution, the positioning block is plugged into and matched with the positioning groove, thereby realizing the positioning of the water spraying part.

[0019] Optionally, the cutter body is sleeved on the cutter handle and is plugged and matched with the positioning block for positioning. The cutter handle is provided with a positioning component for positioning the cutter body, and the positioning component includes:

[0020] A positioning plate, the positioning plate is plug-fitted with the positioning block;

[0021] A positioning screw passes through the positioning disc and is threadably connected to the tool handle so that the positioning disc is pressed against the tool disc body for positioning.

[0022] By adopting the above technical solution, the cutter body is sleeved on the cutter handle so that the positioning block is plugged into the cutter body, and then the positioning disk is pressed against the cutter body. The positioning screw passes through the positioning disk and is threadedly connected to the cutter handle so that the positioning disk is pressed against the cutter body for positioning. The positioning block can position the cutter body, the water spray part and the positioning disk, so that the cutter body and the water spray part rotate together, thereby improving the cooling effect on the cutter body and reducing the probability of the positioning disk rotating, thereby improving the positioning effect on the cutter body.

[0023] Optionally, the tool handle is provided with a mounting hole which is threadedly connected to the positioning screw and communicated with the channel.

[0024] By adopting the above technical solution, the mounting hole is connected with the channel, making the processing of the mounting hole channel more convenient. The channel is blocked by the positioning screw, so that the coolant flows out through the water hole, and the coolant can also cool the positioning screw, thereby improving the positioning effect of the cutter disc body.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] The channels and water holes are processed when processing the tool handle, and the coolant sprayed from the multiple water holes flows out through the water holes. Therefore, the aperture of the water hole is much larger than the aperture of the water hole, and the sum of the length of the water hole, the thickness of the water storage cavity and the length of the water hole in the present application is the same as the length of the water hole in the prior art, thereby shortening the length of the drill bit when processing the water hole, and at the same time increasing the aperture of the hole through the water hole, thereby greatly reducing the processing difficulty, and making the water hole processing able to better realize the cooling of the cutter head body, thereby improving the cooling effect of the cutter head body.
