TECHNICAL FIELD

[0001] The utility model relates to a tool anti chip removal structure for milling field. BACKGROUND

[0002] When milling is carried out by using the existing tool, the aluminum chips flow along the flowing direction of the external cutting fluid, the aluminum chips cut down flow into the product cavity, resulting in unqualified product cleanliness, which cannot meet the production demand. Therefore, after the processing is completed, the aluminum chips falling in the product cavity are cleaned by manually blowing with an air gun. However, the cleaning process is still inefficient and the effect is poor. SUMMARY

[0003] The utility model aims at overcoming the defects of the prior art, and provides a tool anti chip removal structure, which can automatically remove the chips and scraps.

[0004] One technical solution to achieve the above-mentioned purpose is that a cutting fluid channel is formed in the center of the tool body in the axial direction, the cutting fluid channel leads to the bottom of the tool body, a water containing groove is arranged at the bottom of the tool body, the outlet of the cutting fluid channel is opposite to the center of the water containing groove, a group of water outlets are arranged on each milling surface of the tool body corresponding to the side surface of the water containing groove, and the water outlets lead to the water containing groove.

[0005] Further, the water containing groove is provided with a backflushing surface in the direction leading to the water outlet.

[0006] Further, each group of water outlets is composed of upper water outlets and lower water outlets arranged in sequence from top to bottom.

[0007] Further, the bottom surface of the hole of each water outlet is a slope surface upward, the direction of the slope surface is opposite to the tool feeding direction, and the included angle between the bottom slope surface of the hole of the upper water outlet and the vertical direction is smaller than the included angle between the bottom slope surface of the hole of the lower water outlet and the vertical direction.

[0008] Further, the included angle between the bottom slope surface of the hole of the upper water outlet and the vertical direction is 30°, and the included angle between the bottom slope surface of the hole of the lower water outlet and the vertical direction is 60°.

[0009] The advantage effect of the utility model is that the tool anti chip removal structure of the utility model adopts the structure form that the cutting fluid impacts the water containing groove at the bottom of the tool body and then backflushes through the water outlet, so that in the processing process, the aluminum chips flow along the flowing direction of the cutting fluid, and the aluminum chips have a movement trend of flowing to the outside of the cavity, which can greatly reduce the number of aluminum chips remaining in the cavity. In this way, the workload of blowing operation after processing can be reduced, the production efficiency is improved, and the product cleanliness is improved. BRIEF DESCRIPTION OF DRAWINGS

[0013] In order to better understand the technical scheme of the utility model, the following will be explained in detail through specific examples:

[0014] Please refer to Figure 1 The utility model discloses a cutter counter chip removal structure, a cutting fluid channel 1 is set up in the central part of the cutter body along the axial direction, the cutting fluid channel 1 is connected with the cutting fluid circulation system, and the cutting fluid circulation system and the cutter are controlled by the numerical control machine tool together. The cutting fluid circulation system pumps the cutting fluid into the cutting fluid channel 1 at high speed.

[0015] The cutting fluid channel 1 leads to the bottom of the cutter body, and a water containing groove 2 is arranged on the bottom surface of the cutter body, and the outlet of the cutting fluid channel 1 is opposite to the center of the water containing groove 2. The water containing groove 2 is provided with a backflushing surface 3 in the direction leading to the water outlet hole, and the backflushing surface 3 is located on the opposite side of the water outlet hole. The backflushing surface 3 can make the effect of the cutting fluid backflushing towards the water outlet hole better.

[0016] After the cutting fluid in the cutting fluid channel 1 is sprayed out, the backflushing surface 3 of the water containing groove 2 forms a backflushing force. A group of water outlet holes are arranged on each milling surface of the cutter body corresponding to the side surface of the water containing groove, and the water outlet holes lead to the water containing groove 2. After the cutting fluid backflushes, the cutting fluid is sprayed out through the water outlet holes to flush the cutter body, and at the same time, the cutting fluid can take out the cutting scraps in the cavity when the cutter body is used for cutting operation.

[0017] In the embodiment, each group of water outlet holes is composed of the upper water outlet hole 4 and the lower water outlet hole 5 arranged in sequence from top to bottom. The bottom surface of the hole mouth of each water outlet hole is a slope surface upward, the direction of the slope surface is opposite to the feeding direction of the cutter, and the included angle between the bottom slope surface of the hole mouth of the upper water outlet hole and the vertical direction is smaller than the included angle between the bottom slope surface of the hole mouth of the lower water outlet hole and the vertical direction. In the embodiment, the included angle a between the bottom slope surface of the hole mouth of the upper water outlet hole and the vertical direction is 30 DEG, and the included angle b between the bottom slope surface of the hole mouth of the lower water outlet hole and the vertical direction is 60 DEG. The different spraying angles of the cutting fluid of the upper and lower water outlet holes can improve the spraying dispersion effect of the cutting fluid. The specific number of the water outlet holes is not limited, and the function of the water outlet holes is to make the backflushed cutting fluid sprayed to the outside of the machined cavity through the water outlet holes instead of flowing along the cutter body to the feeding direction, so that as many cutting scraps as possible can be taken out.

[0018] Please refer to Figure 2The specific implementation steps of the utility model are as follows:

[0019] 1. Since the cutter body diameter of the utility model is larger than that of the traditional cutter, the hole diameter of the to-be-processed cavity needs to be confirmed to meet the cutter requirement of the utility model before the utility model is adopted.

[0020] 2. It is confirmed whether the to-be-processed blank has a pre-cast hole, and if yes, the cutter of the utility model can be directly used for processing. If there is no pre-cast hole, a drill bit with a size smaller than the processing hole diameter can be used for pre-drilling, and then the cutter of the utility model is used for processing.

[0021] 3. During processing, the program internal cooling instruction of the numerical control machine tool is first opened, the cutting fluid circulation is started, and then the processing is performed. Figure 2 As shown in the figure, the arrow direction is the feed direction, the cutting fluid is backflushed to the outside of the cavity in the processing process, which is opposite to the feed direction, so that most of the cutting debris will follow the flow direction of the cutting fluid, thereby being discharged to the outside of the cavity.

[0022] Those skilled in the art in the technical field should realize that the above embodiments are only used to illustrate the utility model, and are not used as the limitation of the utility model, as long as the changes and modifications of the above described embodiments are within the scope of the utility model, which will fall within the scope of the claims of the utility model.
