Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a high-precision machining tool for rotor shaft body holes. Background Technology

[0002] In the field of rotor shaft machining, the machining accuracy of the shaft bore directly affects the assembly accuracy and operational stability of the rotor shaft, and its machining quality is crucial to the overall operating efficiency and service life of the machine. Currently, rotor shafts are mostly arc-shaped structures, and existing machining processes often employ the method of directly drilling holes into the arc surface.

[0003] This traditional machining method has significant technical drawbacks: First, the arc surface lacks an effective guiding and positioning structure, causing the drill bit to easily slip along the arc surface after contacting the shaft, leading to hole position misalignment and failing to meet high-precision assembly requirements. Second, during drilling, the contact between the arc surface and the drill bit is point or line contact, resulting in uneven force distribution that easily causes machining vibration, further exacerbating hole position deviation and affecting hole wall smoothness. Third, vibration and slippage cause the drill bit to be subjected to irregular impact forces, which not only accelerates drill bit wear and reduces tool life but also easily causes drill bit breakage, increasing machining costs and the risk of project delays. These problems severely restrict the machining accuracy and production efficiency of rotor shaft body holes, making it difficult to meet the high-precision requirements of high-end equipment for component machining.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a high-precision machining tool for rotor shaft body holes, making it more valuable for industrial use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a high-precision machining fixture for rotor shaft body holes.

[0006] This utility model discloses a high-precision rotor shaft body hole machining fixture, including a shaft body, a drilling guide seat is sleeved on the shaft body, the surface of the drilling guide seat is provided with a guide hole for guiding the drilling, the inner side of the drilling guide seat is annular, and the drilling guide seat is tightly fitted to the shaft body.

[0007] A high-precision rotor shaft bore machining fixture includes a shaft body and a drilling guide seat sleeved on the shaft body. The inner side of the drilling guide seat is designed as an annular shape so that it can fit tightly with the shaft body. The guide holes set on its surface can provide precise guidance for the drilling operation, effectively avoiding the problem of deviation during drilling, helping to improve the positional accuracy and operational stability of the shaft bore machining, while simplifying the machining operation process and making the shaft bore machining more efficient and convenient.

[0008] Furthermore, the surface of the punch guide is provided with multiple sets of planar guide surfaces, and the guide holes are located on the guide surfaces.

[0009] The surface of the drilling guide seat is provided with multiple sets of planar guide surfaces, with guide holes arranged on each guide surface. The planar structure can provide stable support for the drill bit. With the precise positioning of the guide holes, it reduces shaking and offset during drilling, further improving the perpendicularity and hole position consistency of the shaft hole machining, making the drilling operation more stable and reliable.

[0010] Furthermore, multiple heat dissipation windows are provided on the side wall of the perforated guide seat.

[0011] The side wall of the drilling guide is equipped with multiple heat dissipation windows, which can quickly dissipate the heat generated during the drilling operation, avoid the high temperature from affecting the drilling guide, drill bit and spindle, maintain the temperature stability of the processing, protect the performance of related components, extend service life, and ensure continuous and smooth drilling operation.

[0012] Furthermore, a guide sleeve is installed in each guide hole by means of an interference fit.

[0013] Each guide hole is equipped with a guide sleeve, which is securely connected to the guide hole through an interference fit. This provides precise guidance and reliable support for the drill bit, reduces drill bit wear, improves the stability of the drilling process, ensures the accuracy and consistency of the shaft hole machining, and makes the drilling operation smoother and more efficient.

[0014] Furthermore, the surface of the shaft body is provided with an upwardly protruding positioning key at the position where it contacts the drilling guide seat, and the inner side of the drilling guide seat has a positioning groove that cooperates with the positioning key.

[0015] The surface of the shaft body is provided with an upward-protruding positioning key at the contact point with the drilling guide seat. The inner side of the drilling guide seat is provided with a positioning groove that cooperates with the positioning key. The precise engagement of the two can quickly achieve circumferential positioning of the shaft body and the drilling guide seat, avoid hole position deviation caused by relative rotation during the processing, improve installation alignment efficiency, ensure the position matching degree between the guide hole and the preset hole position of the shaft body, and enhance the overall structural stability of the tooling.

[0016] Furthermore, the surface of the shaft has an upwardly protruding limiting ring, and the inner side of the drilled guide seat has a limiting ring that cooperates with the limiting ring.

[0017] The shaft surface is provided with an upwardly protruding limiting ring, and the inner side of the drilling guide is equipped with a matching limiting ring. The precise fit between the two can realize the axial limitation of the shaft and the drilling guide, avoid relative axial displacement during processing, ensure the accuracy of the drilling position, and improve the structural stability of the tooling after assembly, making the drilling operation more stable and reliable.

[0018] By means of the above-described solution, the present invention has at least the following advantages: 1. Precise guidance and positioning to ensure machining accuracy: The drilling guide seat fits tightly with the shaft body, and the guide hole and guide surface provide stable support and precise guidance for the drill bit. The positioning key and positioning groove, and the limit stop ring and limit ring respectively realize circumferential and axial positioning. Multiple protections completely avoid drill bit slippage, hole position deviation and machining vibration, greatly improve the positional accuracy, perpendicularity and hole position consistency of the shaft body hole, and meet the high-precision assembly requirements of high-end equipment.

[0019] 2. Protect components and improve efficiency, reduce processing costs: The guide sleeve provides reliable support for the drill bit, reducing wear and breakage caused by irregular impacts; the heat dissipation window quickly dissipates processing heat, preventing high temperatures from affecting the performance of various components and extending the service life of tooling and drill bits; at the same time, it simplifies the installation and alignment process, improves assembly and processing efficiency, reduces the risk of project delays, and lowers overall processing costs.

[0020] 3. Stable structure and convenient operation, enhancing practicality: All components fit together tightly, the overall structure is stable, there is no relative displacement during processing, ensuring stable operation; the tooling design is simple, the operation process is easy to understand, adaptable to different processing scenarios, taking into account practicality and ease of use, and has broad industrial application value.

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] See Figure 1 and Figure 2 When this high-precision rotor shaft bore machining fixture is in operation, the drilling guide seat 2 is sleeved on the shaft body 1. The annular structure on the inner side of the drilling guide seat 2 makes it fit tightly against the shaft body 1. The drilling operation is carried out through the guide hole 3 on the surface of the drilling guide seat 2. The guide hole 3 provides precise guidance for the drill bit and effectively avoids drilling deviation. At the same time, the tight fit between the drilling guide seat 2 and the shaft body 1 ensures the stability of the machining process, greatly improves the machining accuracy of the shaft body bore, and makes the operation more convenient and efficient.

[0026] See Figure 2 The multiple planar guide surfaces 4 on the surface of the drilling guide seat 2 provide stable support for drilling. The guide holes 3 are correspondingly set on the guide surfaces 4. The drill bit performs drilling operations along the guide holes 3. The planar structure of the guide surfaces 4 can reduce drill bit shaking. The guide holes 3 accurately control the drilling direction. The two work together to further improve the perpendicularity and hole position consistency of the shaft hole processing, making the drilling process more stable and reliable, and effectively ensuring the processing quality.

[0027] When this high-precision rotor shaft bore machining fixture is in operation, the drilling guide 2 generates heat during the drilling process. Multiple heat dissipation windows 5 on its side wall can quickly dissipate this heat, preventing high temperature from adversely affecting the drilling guide 2, drill bit and shaft 1, maintaining stable temperature during the machining process, protecting the performance of each component and extending its service life, ensuring continuous and smooth drilling operations, reducing machining failures caused by high temperature, and improving overall machining efficiency.

[0028] The guide sleeve 6, installed with an interference fit, is firmly connected to the guide hole 3, providing precise guidance and reliable support for the drill bit, reducing wear and wobble of the drill bit during operation, ensuring the accuracy and consistency of the shaft hole machining, making the drilling operation smoother and more efficient, while extending the service life of the drill bit and the guide hole 3 and reducing machining losses.

[0029] See Figures 3-5The drilling guide seat 2 is fitted onto the shaft body 1. The positioning key 7 on the surface of the shaft body 1 and the positioning groove 8 on the inner side of the drilling guide seat 2 are precisely engaged, which quickly achieves circumferential positioning of the two, avoids relative rotation during processing, ensures that the guide hole 3 and the preset hole position of the shaft body 1 are accurately matched, effectively prevents hole position deviation, improves installation alignment efficiency, enhances the overall structural stability of the tooling, and makes the drilling operation more accurate and efficient.

[0030] The limiting ring 9 on the surface of the shaft 1 and the limiting ring 10 on the inner side of the drilling guide 2 are precisely fitted together to achieve axial limiting of the shaft 1 and the drilling guide 2, avoiding relative axial displacement between the two during the processing, ensuring that the guide hole 3 is always aligned with the preset drilling position of the shaft 1, effectively ensuring the accuracy of the hole position, while enhancing the structural stability after tooling assembly, making the drilling operation more stable and reliable, and improving the overall processing quality and efficiency.
