Description

Technical Field

[0001] This invention relates to composite trimming tools. Background Technology

[0002] During the machining process of parts, it is necessary to trim the edges of the parts. Since the edge angles of the parts are not the same, the angle of the cutting tool usually needs to be adjusted repeatedly during trimming. In the process of batch trimming, repeated adjustments will slow down the overall production efficiency. Summary of the Invention

[0003] The main objective of this invention is to provide a composite trimming tool structure that can trim two or more edges of a part without adjusting the angle.

[0004] To achieve the above objectives, the present invention provides a part trimming tool, including a cutting head rotatable about a first axis, wherein the cutting head has the following components arranged sequentially along the first axis:

[0005] The first rotating part has a first blade mounting groove, and the first blade is fixed in the first blade mounting groove to form a first cutting angle.

[0006] The second rotating part has a second blade mounting groove, and the second blade is fixed in the second blade mounting groove to form a second cutting angle.

[0007] In some embodiments of the present invention, the first rotating part is a first cylinder whose central axis is coaxial with the first axis, and the second rotating part is a second cylinder whose central axis is inclined to the first axis.

[0008] In some embodiments of the present invention, the first blade mounting groove extends from one side of the first rotating part to the other side of the first rotating part, and forms a first cutting edge on one side of the surface of the first rotating part. The cutting edge of the first blade is exposed in the first cutting edge and forms a first cutting angle.

[0009] In some embodiments of the present invention, the first rotating part is provided with a first stud hole on one side of the first blade mounting groove, and a first stud is installed in the first stud hole, and the first stud is pressed against the surface of the first blade.

[0010] In some embodiments of the present invention, the cutting edge of the first blade and the edge of the first cutting opening have a first gap, and a first discharge groove is provided on one side of the first rotating part, the bottom of the first discharge groove communicating with the first gap.

[0011] In some embodiments of the present invention, the second blade mounting groove extends from one side of the second rotating part to the other side of the second rotating part, and forms a second cutting edge on one side of the surface of the second rotating part. The cutting edge of the second blade is exposed in the second cutting edge and forms a second cutting angle.

[0012] In some embodiments of the present invention, the second rotating part is located on one side of the second blade mounting groove and has a second stud hole, in which a second stud is installed and pressed against the surface of the first blade.

[0013] In some embodiments of the present invention, the edge of the second blade and the edge of the second cutting opening have a second gap, and a second discharge groove is provided on one side of the second rotating part, with the bottom of the second discharge groove communicating with the second gap.

[0014] In some embodiments of the present invention, the first rotating part and the second rotating part are connected head to head.

[0015] The aforementioned composite trimming tool has at least two rotating parts with different cutting angles. When trimming different edges of a part, only the rotating parts with the corresponding cutting angles need to be used for trimming, without the need to adjust the entire tool, thus improving the overall trimming efficiency.

Detailed Implementation

[0021] In view of the fact that existing part trimming tools require constant adjustment to adapt to the trimming of different edges of the part, the present invention provides a part trimming tool that aims to trim at least two or more different edges of the part without tool adjustment. The improvement involves a cutting head in the part trimming tool that is rotatable about a first axis, the cutting head having the following features arranged sequentially along the first axis:

[0022] The first rotating part has a first blade mounting groove, and the first blade is fixed in the first blade mounting groove to form a first cutting angle.

[0023] The second rotating part has a second blade mounting groove, and the second blade is fixed in the second blade mounting groove to form a second cutting angle.

[0024] Therefore, the cutting head of the aforementioned trimming tool can form two different cutting angles corresponding to the edge angles of the part. When it is necessary to cut these corresponding edges, it is only necessary to align the edge of the part with the first rotating part and the second rotating part for trimming, eliminating the need to adjust the entire trimming tool and improving processing efficiency.

[0025] One possible structure for the first rotating part is a first cylinder whose central axis is coaxial with the first axis. Another possible structure for the second rotating part is a second cylinder whose central axis is inclined to the first axis. The manufacturing methods for both are known, such as machining and injection molding. During manufacturing, the cutting angles required for machining the part should be determined in advance. After the cutting head is manufactured, since the insert mounting grooves for the inserts are already determined, all its cutting angles are essentially fixed. For example... Figure 2 The diagram illustrates a first rotating part 110 and a second rotating part 120 sequentially arranged along a first axis α of a workpiece trimming tool. The central axis of the first rotating part, which is cylindrical in shape, coincides with the first axis α, while the central axis β of the second rotating part, also cylindrical in shape, is inclined at a certain angle to the first axis α. The angle of inclination can be arbitrarily chosen, but preferably, it should be ensured that it can be directly connected to the first rotating part in the circumferential direction of the first axis to increase its overall strength. When a direct connection is not possible, a connecting part can be added between the two for connection.

[0026] The method for mounting the first blade on the first rotating part to form the first cutting angle can be referred to... Figure 3The first blade mounting groove 112 extends from one side of the first rotating part 110 to the other side, and forms a first cutting edge 116 on one side of the surface of the first rotating part 110. A first stud hole 114 is provided on one side of the first blade mounting groove 112, and a first stud 115 is installed in the first stud hole 114. In this structure, the first blade 113 can be directly inserted into the first blade mounting groove 112 and secured by the first stud 115. The cutting edge 117 of the first blade slightly protrudes from the first cutting edge 116 to achieve its function of cutting along a first cutting angle. A first gap 118 exists between the cutting edge 117 of the first blade and the edge of the first cutting edge 116. A first discharge groove 111 is provided on one side of the first rotating part, and the bottom of the first discharge groove 111 communicates with the first gap 118. When the cutting edge 118 of the first blade cuts, the remaining material can enter the first discharge groove 111 through the first gap 118 and then be discharged through the opening of the first discharge groove 111.

[0027] The structure of the second rotating part mounting the second cutting insert is similar to the structure of the first rotating part mounting the first cutting insert. However, because the central axis β of the second rotating part has an angle with the first axis α of the compound trimming tool, a second cutting angle can be formed after the second cutting insert is mounted, thus achieving different cutting angles between the first and second rotating parts. Figure 4 As shown, the second blade mounting groove 122 extends from one side of the second rotating part 120 to the other side, and forms a second cutting edge 126 on one side of the surface of the second rotating part 120. A second stud hole 124 is provided on one side of the second blade mounting groove 122, and a second stud 125 is installed in the second stud hole 124. In this structure, the second blade 123 can be directly inserted into the second blade mounting groove 122 and clamped and fixed by the second stud 125. The cutting edge 127 of the second blade slightly protrudes from the second cutting edge 126 to achieve its function of cutting along a second cutting angle. A second gap 128 is formed between the cutting edge 127 of the second blade and the edge of the second cutting edge 126. A second discharge groove 121 is provided on one side of the second rotating part, and the bottom of the second discharge groove 121 communicates with the second gap 128. When the cutting edge 127 of the second blade is cutting, the remaining material can enter the second discharge groove 121 through the second gap 128, and then be discharged through the opening of the second discharge groove 121.

[0028] In addition, the cutter head also has a connection part that connects to the conventional cutter body. The cutter head is connected to the conventional cutter body through this connection part and is driven by the motor of the cutter body to rotate and cut.

[0029] Therefore, when trimming the edges of parts at different angles, it is only necessary to move them to the first and second rotating parts of the cutter head for rotation and cutting, without adjusting the entire compound trimming tool, thus improving processing efficiency.

[0030] The embodiments described in this invention are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the scope of protection of this invention.
