Description

Cutting tool with spray cutting fluid function and nozzle structure thereof

The present invention relates to a cutting tool, and more particularly to an innovative structural type of a cutting tool having a function of spraying a cutting fluid and a nozzle thereof.

According to the cutting tool, most of the processing machine tools are used for milling, drilling, turning, grinding, etc., because of high-speed friction and high heat. Therefore, the cutting tool must be used to cool the tool; the traditional processing machine cools the tool. Usually, a cutting fluid nozzle is used to directly spray the cutting fluid on the processing part. However, it often sags due to the length of the nozzle, and the precision of the cutting fluid is lost, which also reduces the cooling efficiency.

In view of this, manufacturers of cutting tools have begun to develop cutting tools equipped with a cutting fluid spray structure. Although such cutting tools can improve the precision of the cutting fluid spray, there are still many defects to be improved in actual use. For example, if the parts are too complicated and not easy to assemble, the production cost is relatively increased, and after the cost is passed on to the consumers, the competitiveness of the market is reduced. In addition, the spray angle is not easy to adjust. The conventional cutting machine does not have a tool magazine. It is often necessary to change the cutting edge when changing the machining mode. In this case, if it takes too much time to adjust the spray angle of the cutting fluid, the production capacity will be greatly reduced. Affect the progress of work. In addition, often only a set of spray structures is installed. Based on the above two missing, the cutting tool manufacturers often only install a set of spray structures on the cutting tools, which reduces the production cost and shortens the user's adjustment of the spray angle. The time spent, however, the amount of cutting fluid spray provided by a single set of spray structures may not necessarily meet the cooling efficiency required for processing.

The main purpose of this creation is to provide a cutting tool. The technical problem to be solved is to make an innovative breakthrough in how to develop a new type of cutting tool structure that is more ideal and practical.

The technical feature of the present invention is mainly that the cutting tool with the function of spraying the cutting fluid comprises a shank; a blade mounted on the end of the shank; one is disposed on the shank and is for importing a connecting groove of the cutting fluid; at least one flow passage formed in the shank, the first end of the at least one main passage is in communication with the connecting cymbal, and the second end thereof extends to the surface of the shank; at least one And a nozzle structure mounted on the second end of the at least one of the at least one nozzle, the at least one nozzle structure comprising a nozzle and a fixing member for positioning the nozzle on the shank. The nozzle is mounted on the shank and has a perforation and a liquid flow passage, wherein the perforation is respectively communicated with the at least the first passage and the outlet passage; the fixing member penetrates the through hole and is fixed The nozzle is fixed to the shank by the shank; the fixing member is configured with a first-class trajectory, and the flow passage of the fixing member communicates with the at least the first channel and the liquid outlet channel respectively; The outer diameter is smaller than the inner diameter of the perforation, so that the cutting fluid can be sprayed through the perforation and the space of the fixing member and the outlet flow path toward the actual working end of the cutting edge.

With this innovative and unique design, this creation can be compared with the prior art, and the special structural design can achieve practical progress and better industrial utilization benefits such as quick and convenient assembly, easy change of spray direction.

The nozzle 31 is mounted on the shank 10 and has a through hole 311 and a liquid flow path 312, wherein the through hole 311 is in communication with the at least the first flow path 12 and the liquid flow path 312, respectively; The member 32 extends through the through hole 311 and is fixed to the shank 10, thereby fixing the spray head 31 to the shank 10. The fixing member 32 is provided with at least a first-class 321, and at least the first-class 321 of the fixing member 32 Connecting at least the first runner 12 of the shank 10 and the outlet passage 312 of the nozzle 31 respectively; the outer diameter of the fixing member 32 is smaller than the inner diameter of the through hole 311, so that the cutting fluid can pass through the through hole 311 The space between the fixtures 32 and the outlet flow path 312 are sprayed in the direction of the actual working end of the blade 20.

In the preferred embodiment of the present invention, at least one channel 321 provided by the fixing member 32 is at least one groove formed on an outer wall thereof, and the at least one groove is respectively matched with at least one of the shank 10 12 and the perforations 311 are connected to each other to increase the flow rate of the cutting fluid per unit time. The inner wall of the liquid outlet channel 312 is provided with an internal thread portion, and the at least one nozzle structure 30 further includes a nozzle 33 mounted on the internal thread portion, as shown in FIG. The spraying direction of the cutting fluid; the connecting port 11 is further provided with a liquid inlet pipe 40 for supplying the cutting fluid into at least the first runner 12 of the shank 10. The inner wall of the through hole 311 is formed with an annular groove 313 which communicates with the liquid discharge passage 312 to ensure the smooth flow of the cutting fluid in the at least one nozzle structure 30.

The through hole 311 is different from one end of the shank 10 and has a tapered outer expansion portion 314. The fixing member 32 has a head portion 322, and the cross section of the head portion 322 and the outer expansion portion 314 The contours complement each other. The inner wall of the second end of at least the main passage 12 of the shank 10 is provided with an internal thread, and the fixing member 32 is a bolt. When the fixing member 32 is locked to the internal thread of the inner wall of the second end of the main shaft 12 of the shank 10, the contour of the head portion 322 and the outer expansion portion 314 can be During the process of locking the nozzle 31, the nozzle 31 is gradually guided to the positioning, so that the locked nozzle 31 and the fixing member 32 are concentrically corresponding to the second end of the at least one of the shanks 10 respectively.

Further, as shown in the second, third and sixth embodiments, in the present embodiment, the nozzle 31 is further provided with a leak stop ring 315 toward one surface of the shank 10, thereby preventing the leakage of the cutting fluid.

In summary, this creation does have at least the following advantages: 1.

Easily change the spray direction: When the blade is changed due to the operation demand, the spray angle of the cutting fluid must be adjusted due to the different cutting angle. If the adjustment angle is not large, the extension angle of the nozzle can be directly turned. If the adjustment angle is large, the fixing member can be loosened to release the nozzle. When the nozzle is rotated to the angle to be sprayed, the adjustment of the spray angle is completed by directly tightening the fixing member again. 3. This creation can be installed with multiple nozzle structures in the most efficient way to reduce the temperature of the cutting tools and workpieces in the work, and use the cutting fluid to remove the waste, prolong the service life of the cutting tools and improve the machining accuracy.
