Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to an integrated boring and chamfering tool. Background Technology

[0002] In the field of machining and manufacturing mechanical housing components, the external cylindrical feature is a common and critical geometric structure. For some mechanical housing components with high precision requirements, lathes are difficult to meet the machining requirements of external cylindrical features due to their machining principles and precision limitations. However, boring has become a key process for achieving this high-precision external cylindrical feature due to its unique advantages.

[0003] Traditional machining processes require either a boring bar with both positive and negative chamfering tools, or a positive chamfering tool with a negative chamfering tool. However, these two methods necessitate frequent tool changes on the machining equipment. When performing batch processing, this tool change operation not only increases auxiliary processing time and reduces production efficiency, but also negatively impacts the stability and consistency of the machining process, thus becoming a significant factor restricting the improvement of production efficiency.

[0004] In the existing technology patent, a special tool for internal chamfering is disclosed, with the publication number CN1970205A. It can switch the cutting tool between working and non-working states through the rotation design of the eccentric hole and the second tool holder, which is convenient for completing chamfering operations on the outside of housing parts and reducing tool change time. However, this tool is dedicated to internal chamfering and cannot be integrated with boring. The boring and chamfering processes still need to be completed in steps. Its cutting tool switching can only achieve single-sided chamfering. If positive and negative chamfering is required, the tool position still needs to be adjusted or the cutting tool needs to be replaced. It cannot meet the composite chamfering requirements of high-precision housing parts. Utility Model Content

[0005] To address the aforementioned technical problems or one of the technical problems existing in the prior art, this utility model discloses an integrated boring and chamfering tool, comprising a connecting member and a tool body. The tool body is located at the bottom of the connecting member and includes a connecting plate, tool holders, tool arms, boring inserts, and chamfering inserts. Two tool holders are located on the bottom surface of the connecting plate, and the tool arms are fixed to the bottom of the tool holders. The boring inserts and chamfering inserts are located at the bottom of the tool arms. The two tool arms are symmetrically arranged along the axial direction. The boring inserts face the inner side of the two tool arms, and the chamfering inserts face the outer side of the two tool arms. The tips of the two boring inserts are staggered at different heights, and the two chamfering inserts are symmetrically arranged with the same height.

[0006] Furthermore, the connector is cylindrical, with a positioning key at the top for connection to the machine tool, and a frustum fixed at the bottom, which is fixed to the center of the top surface of the connecting plate.

[0007] Furthermore, the bottom surface of the connecting plate is provided with a slide rail, and the two sides of the slide rail are provided with mounting screw holes. The top surface of the tool holder is provided with a slide groove that mates with the slide rail, and the two sides of the slide groove are provided with countersunk screw holes. The tool holder is connected to the connecting plate by screwing the countersunk screw holes and the mounting screw holes in sequence.

[0008] Furthermore, the blade arm is cylindrical.

[0009] Furthermore, the height difference between the tips of the boring inserts is less than 0.2mm, and the machining radius of the boring insert with the higher tip is 0.2mm greater than that of the boring insert with the lower tip.

[0010] Furthermore, the boring insert and the chamfering insert are connected to the tool arm by screws.

[0011] Compared with the prior art, the present invention has two chamfering plates of the same height installed on the outer side of the two boring heads, and can realize the upper and lower chamfering, thus completing the boring and chamfering processes. This saves equipment and tool replacement time and improves processing efficiency. Attached Figure Description

The tool body is located at the bottom of the connecting member 1. The tool body includes a connecting plate 2, a tool holder 3, a tool arm 4, a boring insert 5, and a chamfering insert 6. Two tool holders 3 are located on the bottom surface of the connecting plate 2. The tool arm 4 is fixed to the bottom of the tool holder 3. The boring insert 5 and the chamfering insert 6 are located at the bottom of the tool arm 4. The two tool arms 4 are symmetrically arranged along the axial direction. The boring insert 5 faces the inner side of the two tool arms 4, and the chamfering insert 6 faces the outer side of the two tool arms 4. The tips of the two boring inserts 5 are staggered at different heights. The two chamfering inserts 6 are symmetrically arranged and have the same height.
