Description

Technical Field

[0001] This utility model belongs to the field of cutting tool technology, and in particular relates to a split-type cutting tool with replaceable cutting edges. Background Technology

[0002] In the field of machining, replaceable cutting edge split-type cutting tools are a common type of cutting tool. The core design concept is to use a split structure for the tool body (including the cutting edge) and the tool holder, which are combined into one unit through a detachable connection. The advantage of this design is that when the cutting edge fails due to wear, chipping, or other reasons, it is not necessary to replace the entire tool; only the tool body needs to be replaced. This reduces the cost of tool use and minimizes resource waste. It also facilitates the quick replacement of the appropriate tool body according to different machining needs and is widely used in various machining scenarios such as turning, milling, and drilling.

[0003] Currently, the existing replaceable cutting edge split tool structure is relatively simple, typically consisting of three parts: a tool holder, a stud, and a tool body. The tool holder serves as the support and connection component for the tool, with one end fixed to the machine tool's fixture and the other end directly connected to the tool body via a stud (or bolt). The tool body is then fastened to the end of the tool holder with bolts, forming a complete cutting tool. This structure was used to some extent in early machining scenarios due to its convenient assembly and low cost.

[0004] However, existing replaceable blade split-type knives have the following drawbacks in practical use: Firstly, in existing technology, the tool body and tool holder are directly fixed by bolts, and their relative angle remains constant. However, in actual machining, different types of workpieces (such as irregularly shaped parts, multi-angle inclined surfaces, etc.) often require the tool to cut at a specific angle. In this case, limited by the fixed angle design, the operator can only meet the machining requirements by changing the entire set of tools. Secondly, in existing technologies, the machine tool's coolant delivery mechanism typically relies on spraying coolant onto the tool body to achieve cooling. However, due to the high surface temperature of the tool body and the presence of impurities such as oil film and iron filings during the cutting process, the coolant sprayed onto the tool body surface easily forms a dense film structure. This film structure will block the direct contact between the subsequently sprayed coolant and the tool body surface, resulting in a significant decrease in cooling effect and difficulty in effectively controlling the tool body temperature, thereby affecting machining quality and tool stability.

[0005] Therefore, it is essential to invent a split-type knife with interchangeable blades. Utility Model Content

[0006] To address the above problems, this utility model proposes a split-type knife with replaceable cutting edges. The technical solution used is as follows: A detachable cutting tool with replaceable blades includes a handle, an angle adjustment bracket, a fixing post, a first stud, a blade body, and a cooling mechanism. One end of the handle is fixed to the fixing post via the angle adjustment bracket, and the other end of the fixing post is fixed to the blade body via the first stud. The upper side of the fixing post is fixed to the cooling mechanism via bolts.

[0007] Furthermore, the angle adjustment bracket includes a limiting plate, a locking plate, a second stud, a protrusion, and a slot. The limiting plate is fixed to one end of the tool holder by welding, and the upper side of the limiting plate is fixed to the locking plate by the second stud. The outer side of the locking plate is fixed to a fixing post by welding. The upper side of the limiting plate is integrally provided with several protrusions, and the lower side of the locking plate is provided with several slots that are adapted to the protrusions. This arrangement can fix the fixing post to the tool holder, and secondly, it can make the angle of the tool body adapt to the processing requirements of different workpieces.

[0008] Furthermore, the cooling mechanism includes a housing, a power supply, a control switch, exhaust vents, a semiconductor cooling plate, and a fan. The housing is bolted to the upper side of a fixed column, and the power supply and control switch are bolted to the upper side of the housing. Several exhaust vents are provided on the side of the housing near the tool body, and several fans are bolted to the side of the housing away from the tool body. Dustproof mesh made of woven metal wire is fixed inside each exhaust vent. Several semiconductor cooling plates are bolted to the inner wall of the housing, with the cold end of the semiconductor cooling plate located inside the housing and the hot end located on the outer side of the housing. The semiconductor cooling plate and the fan are electrically connected to the control switch via data cables, and the other end of the control switch is electrically connected to the power supply via a data cable. This configuration allows for cooling of the tool body. Furthermore, when the machine tool's coolant delivery mechanism sprays coolant onto the tool body, the gas can blow away the coolant adhering to the tool body.

[0009] Furthermore, a number of heat dissipation fins are fixed to the outer side of the hot end of the semiconductor cooling plate by bolts. These heat dissipation fins are all arranged on the outer side of the outer shell. This arrangement will improve the heat dissipation efficiency of the hot end of the semiconductor cooling plate.

[0010] Furthermore, several temperature-conducting pillars are fixed between the cold ends of the corresponding semiconductor refrigeration plates. These temperature-conducting pillars are all located inside the outer casing. This arrangement can improve the cooling efficiency of the semiconductor refrigeration plates for the gas inside the outer casing.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The angle adjustment bracket of this utility model can fix the fixing post to the tool holder. Secondly, by loosening the second stud and then adjusting the angle of the locking plate on the limit plate, the angle between the fixing post and the tool holder can be adjusted so that the angle of the tool body can adapt to the processing requirements of different workpieces. The cooling mechanism of this invention allows the fan to draw external gas into the housing. This gas is cooled by the cold end of the semiconductor cooling plate. Then, the gas is sprayed onto the tool body through the exhaust port, thereby cooling the tool body. At the same time, when the machine tool's coolant delivery mechanism sprays coolant onto the tool body, the gas can blow away the coolant adhering to the tool body, thus preventing the coolant from forming a film-like structure on the tool body (when the coolant forms a film-like structure, the film-like structure will prevent the subsequently sprayed coolant from contacting the tool body).

[0021] Specifically, the angle adjustment bracket 2 includes a limiting plate 21, a locking plate 22, a second stud 23, a protrusion 24, and a slot 25. The limiting plate 21 is fixed to one end of the tool holder 1 by welding, and the upper side of the limiting plate 21 is fixed with the locking plate 22 by the second stud 23. The outer side of the locking plate 22 is fixed with a fixing post 3 by welding. The upper side of the limiting plate 21 is integrally provided with several protrusions 24, and the lower side of the locking plate 22 is provided with several slots 25 that are adapted to the protrusions 24. This arrangement can fix the fixing post 3 to the tool holder 1. Furthermore, by loosening the second stud 23 and adjusting the angle of the locking plate 22 on the limiting plate 21, the angle between the fixing post 3 and the tool holder 1 can be adjusted, so that the angle of the tool body 5 can adapt to the processing requirements of different workpieces.

[0022] Specifically, the cooling mechanism 6 includes a housing 61, a power supply 62, a control switch 63, exhaust vents 64, a semiconductor cooling plate 65, and a fan 66.

With this arrangement, the temperature-conducting columns 68 can conduct the temperature of the cold ends of the semiconductor refrigeration plate 65, thereby improving the cooling efficiency of the semiconductor refrigeration plate 65 for the gas inside the outer casing 61.
