Description

Technical Field

[0001] This utility model relates to the field of machine tool processing technology, and in particular to an integrated tool for chamfering and boring engine cylinder bores. Background Technology

[0002] In engine block machining, cylinder bore chamfering and boring are two key processes, respectively ensuring the precision of the cylinder bore and the reliability of assembly. The two are closely related and jointly affect the engine's performance and lifespan. Boring is the core process for precision machining of engine cylinder bores. Its purpose is to correct the size, shape, and positional accuracy of the cylinder bores through cutting, providing a foundation for the efficient operation of pistons and piston rings. Chamfering, on the other hand, is an auxiliary process for assembly and reliability, indirectly affecting the engine's sealing and lifespan. Although the two have different functions, they need to be controlled in a coordinated manner to ensure the engine's power, economy, and durability.

[0003] When it is necessary to chamfer and bore engine cylinders, corresponding cutting tools are required. Most existing cutting tools for chamfering and boring engine cylinders adopt a segmented design, with the cutting tool, tool holder, and connecting boring head connected separately. When the same cutting head needs to be switched from engine cylinder chamfering to boring, the boring head must be disassembled first, and then the corresponding cutting tool must be replaced. After replacement, tool setting is required, which reduces processing efficiency and service life. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an integrated tool for chamfering and boring engine cylinders, aiming to improve the existing technology where the tool for chamfering and boring engine cylinders requires first disassembling the boring head and then replacing the corresponding inserts, and after replacement, tool setting is required, resulting in reduced processing efficiency and reduced service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated tool for chamfering and boring engine cylinder bores, comprising a tool body, a tool groove on the left side of the outer wall of the tool body, a blade on the inner wall of the tool groove, an angled opening on the outer wall of the blade, and mounting holes in the middle of the inner walls of both the tool groove and the blade.

[0006] As a further description of the above technical solution:

[0007] A diameter groove is provided at the right end of the blade.

[0008] As a further description of the above technical solution:

[0009] A mounting plate is fixedly connected to the middle of the outer wall of the blade.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the mounting plate is provided with a mounting groove.

[0012] As a further description of the above technical solution:

[0013] A positioning groove is provided in the middle of the inner wall of the diameter groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the cutting tool is rotated at high speed by starting the machine tool. The cutting tool moves to the edge of the engine cylinder port, and the bevel angle of the cutting tool begins to chamfer the edge of the cylinder port. The special angle formed by the bevel angle allows the rotation of the cutting tool to perform chamfering and bore machining along the axial direction and the chamfering direction, respectively. At the same time, only the cutting tool needs to be installed, and the cutting head does not need to be installed, which achieves the purpose of integrated machining, extends the service life, and improves work efficiency.

[0016] 2. In this utility model, the cutting tool is connected and fixed to other parts of the machine tool through the mounting plate and mounting groove, thereby ensuring that the cutting tool is firmly installed, the rotation center coincides with the center of the engine cylinder, and the diameter groove can provide a channel for cutting fluid while assisting in installation and positioning.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see the appendix Figure 2 - Appendix Figure 4 An embodiment of this utility model provides: an integrated tool for chamfering and boring engine cylinder bores, including a tool body 1, a tool groove 7 is provided on the left side of the outer wall of the tool body 1, a blade 2 is provided on the inner wall of the tool groove 7, an angled angle 8 is provided on the outer wall of the blade 2, and mounting holes 3 are provided in the middle of the inner walls of the tool groove 7 and the blade 2.

[0025] Specifically, the shape and size of the groove 7 match the blade 2 to ensure that the blade 2 can be embedded therein. The depth and width of the groove 7 must ensure that the blade 2 is installed firmly and provide sufficient support for the blade 2 during the cutting process. The presence of the bevel angle 8 allows the blade 2 to cut into the material at a more suitable angle during the cutting process.

[0026] Please see the appendix Figure 1 - Appendix Figure 3 A diameter groove 5 is provided at the right end of the blade 1, and a positioning groove 9 is provided in the middle of the inner wall of the diameter groove 5.

[0027] Specifically, the diameter groove 5 and the positioning groove 9 can cooperate with each other to connect the tool body 1 to the machine tool.

[0028] Please see the appendix Figure 2 - Appendix Figure 4 A mounting plate 6 is fixedly connected to the middle of the outer wall of the blade 1; specifically, the mounting plate 6 can cooperate with other structures to connect the cutting tool and the machine tool.

[0029] Please see the appendix Figure 2 - Appendix Figure 3 The outer wall of the mounting plate 6 is provided with a mounting groove 4;

[0030] Specifically, the mounting slot 4 is used in conjunction with the mounting plate 6 to quickly connect the tool to the machine tool spindle.

[0031] Working principle: The positioning groove 9 plays a guiding and positioning role. After the tool is installed on the machine tool spindle and the machine tool is started, the tool rotates at high speed and moves to the edge of the engine cylinder. The chamfer 8 of the insert 2 begins to chamfer the edge of the cylinder, removing excess material and forming the required chamfer. After the chamfer is completed, the tool continues to penetrate into the cylinder and makes a linear feed motion along the axis. The insert 2 performs boring on the inner wall of the cylinder, so that the inner diameter of the cylinder reaches the specified size and accuracy requirements, in which the chamfer 8 can pass.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
