Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of machining, in particular to a shock-absorbing quick-change boring tool. Background Art
[0002] The crankshaft is one of the very important parts in an engine, and it plays an important role in converting the piston movement into rotational movement. The design and manufacturing quality of the crankshaft directly affect the performance and reliability of the engine. Facing the increasingly fierce market competition, the types of crankshaft products are constantly updated to meet the needs of new models. In formulating the process regulations, the compatibility of the cutting tools should be considered to process the parts that meet the drawing and technical requirements reliably at the lowest cost and at the planned speed. Content of the Utility Model
[0003] Purpose of the utility model: To provide a shock-absorbing quick-change boring tool to solve the above problems existing in the prior art.
[0004] Technical solution: A shock-absorbing quick-change boring tool, including a main body and a cutting tool. The cutting tool is arranged in the middle of the main body. A shock-absorbing ring is arranged inside the main body. The shock-absorbing ring is fixedly connected with the inside of the main body through shock-absorbing ring fixing screws. A chamfering tool holder and a boring tool holder are respectively arranged inside the main body. The chamfering tool holder is close to the front section of the main body, and the boring tool holder is close to the tail section of the main body.
[0005] In a further embodiment, the chamfering tool holder includes an upper chamfering tool holder and a lower chamfering tool holder, and the upper chamfering tool holder and the lower chamfering tool holder are respectively fixedly connected with the inner wall of the main body.
[0006] In a further embodiment, an axial adjustment screw and a radial adjustment screw are respectively arranged on one side of the cutting tool.
[0007] In a further embodiment, the shock-absorbing ring is sleeved outside the cutting tool.
[0008] Advantageous Effects
[0009] 1. One cutting tool can be used to complete the rough machining of the small ends of two products, which can greatly save the cutting tool cost.
[0010] 2. The shock-absorbing ring at the front end of the cutting tool can stably ensure the appearance quality and accuracy of the product.
[0011] 3. This product has a novel design structure and strong stability. It can be widely applied to the crankshaft machining process, greatly improving the machining efficiency while perfectly ensuring the product accuracy and reducing the crankshaft machining cost. Description of the Drawings

[0019] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model.
[0020] However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details.
[0021] In other examples, in order to avoid confusion with the present utility model, some well-known technical features in the art are not described.
[0022] As Figures 1-6 shown, the shock-absorbing quick-change boring tool is composed of a main body 1, an upper chamfering tool holder 2, a boring tool holder 3, a shock absorption ring fixing screw 4, a shock absorption ring 5, and a lower chamfering tool holder 6.
[0023] 1. The rough machining of the small ends of two types of crankshafts ( Figure 3 ) can be achieved by replacing the chamfering tool holder; during the assembly process, when installing the chamfering tool holder ( Figure 4 ), the processed product ( Figure 4 right-side view), and when disassembling the chamfering tool holder ( Figure 3 ), the processed product ( Figure 4 left-side view); Figure 3
[0024] 2. As designed for the boring tool holder 3 in Figure 1 , the adjustment of the finishing allowance of the outer diameter can be achieved. As in Figure 2 , the radial adjustment screw can adjust the machining diameter D of the tool, with a variable range of 0 to 0.4 mm, and the axial adjustment screw can adjust the end face runout accuracy of the blade;
[0025] Due to the limitation of the machining length of the small end, when the shock absorption ring 5 is designed, the tool body itself during tool machining, as in Figure 6The positions of the upper tool body and the lower tool body are prone to deformation and vibration due to the cutting reaction force. The design of the damping ring 5 with the clearance between the inner diameter of the damping ring and the outer diameter D1 of the tool body less than 0.005 mm and locked and fixed can play a good damping role and improve the surface quality of the processed product.
[0026] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solution of the present invention, and these equivalent transformations all fall within the protection scope of the present invention.
