First, one of the application fields (aero-engine) of the embodiment of the present application will be briefly described below.
An Aircraft engine (Aircraft engine) refers to an engine device that is used primarily to generate a pulling or pushing force to advance an Aircraft. Besides generating forward force, the device can also provide electric power for electric equipment on the airplane and provide air source for air-using equipment such as air conditioning equipment. Generally, the design is relatively light due to flight requirements, but the design requires a relatively high use efficiency and a very low failure rate, so the process requirements for designing and producing the aircraft are relatively high. The main performance indexes of the aircraft engine include fuel consumption rate, thrust-weight ratio and the like. Air-dependent engines include piston engines, aero gas turbines, ramjet engines, detonation engines, and the like, wherein aero gas turbines include turbojet engines, turbofan engines, turboprop engines, paddle fan engines, turboshaft engines, and the like.

With the continuous improvement of the performance requirements of the aero-engine, the processing difficulty of parts of the aero-engine is also continuously improved. The existing machining method for the first-stage bladed disk with the shaft diameter has the technical problems of multiple working procedures, long manufacturing period, machining deformation and the like.
Method embodiment
A method, a system, an electronic device and a storage medium for machining a rotary workpiece are provided to reduce machining processes, achieve rapid prototyping among multiple processes, and achieve high machining yield, high efficiency and easy machining.
Fig. 1 is a schematic flow chart of a method for processing a rotary workpiece according to an embodiment of the present disclosure.
The method is used for processing a blank into a rotary workpiece by using turning and milling composite equipment, wherein the rotary workpiece is a first-stage blade disc with a shaft diameter, and the method comprises the steps of S1-S4.
S1: roughly turning the air inlet side of the blank to remove large allowance of the air inlet side, reserving a process table at the hub of the air inlet side of the blank, milling the hub of the air inlet side of the blank to form an angular groove, and taking the angular groove as an angular reference.
The blank is a raw material which is not processed yet, can also refer to a part before the finished product is finished, and can be a casting part, a forging part or a material obtained by sawing, gas cutting and the like, such as blank ceramics and the like. In the embodiment of the present application, the blank refers to a blank of a rotary body (for example, an alloy material may be used) for machining a rotary workpiece, a product obtained after performing all machining processes on the blank is referred to as a rotary workpiece (for example, a blade disc), and the names of the "blank" and the "rotary workpiece" are used only for distinguishing the states of the workpiece before and after machining, and the blank gradually approaches the final shape of the rotary workpiece during machining. Of course, the initial blank may be referred to as a "blank", and the intermediate product in the machining process and the final product obtained by the final machining may be referred to as a "rotary workpiece", which is not limited in the embodiments of the present application.
Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a blank provided in an embodiment of the present application, and fig. 3 is a schematic structural diagram of a blank after rough turning of an air intake side provided in an embodiment of the present application, where the blank in the embodiment of the present application may be a blank of a rotary body.
In the present application, the chain line in fig. 2, 3, 4, 6, 7, 8, 11 indicates the axis of rotation of the blank, and the thick solid line in fig. 3, 4, 6, 7, 8, 11 indicates the workpiece processing line.
The embodiment of the application does not limit the processing equipment adopted in the processing process, and the processing equipment can be a five-axis processing center or a turning and milling composite machine tool.
Five-axis machining centers combine high speed and high rigidity, with multi-faceted machining capabilities that allow complex workpieces to be machined in a single setup. The five axes of a five-axis machining center generally refer to the ability of a numerically controlled machine tool to move a workpiece or tool on five different CN C axes simultaneously. Wherein standard 3-axis milling is performed on the X, Y and Z axes. These three linear axes are directions in which the spindle or the workpiece can move, and the five-axis machining center also uses two rotation axes out of the following three axes: axis a, axis B and axis C. An A axis: rotation about X-axis, B-axis: rotation around the Y-axis, C-axis: rotating around the Z-axis.
A turning and milling combined machine tool (also called a turning and milling combined machining center) is a machine tool capable of turning and milling, and can complete all or most of machining of a workpiece on the turning and milling combined machine tool, so that the turning and milling combined machine tool is also called a small-sized production line. The machine tool not only can improve the precision of products and the efficiency of processing the products, but also greatly saves the occupied area of the machine tool for enterprises, and only one machine tool is needed to complete the processing of one workpiece in the past. Such machines can also be classified into vertical milling and turning combined and horizontal milling and turning combined machines.
Generally speaking, a five-axis machining center can only perform milling but not turning, so that there are many limitations in machining. That is to say, the turning and milling combined machine tool can cover the processing function of the five-axis machining center, but the five-axis machining center cannot perform the turning and milling combined processing.
Compared with the conventional numerical control machining process, the turning and milling composite machining has the following outstanding advantages:
(1) The manufacturing process chain of the product is shortened, and the production efficiency is improved. The special tool can be installed, the tool changing time is reduced, the machining efficiency is improved, and the turning and milling combined machining can realize one-time clamping to complete all or most machining processes, so that the product manufacturing process chain is greatly shortened. Therefore, on one hand, the production auxiliary time caused by clamping change is reduced, and meanwhile, the manufacturing period and waiting time of the tool fixture are also reduced, and the production efficiency can be obviously improved.
(2) The clamping frequency is reduced, and the processing precision is improved. The reduction of clamping times avoids the accumulation of errors caused by the conversion of the positioning reference. Meanwhile, most turning and milling composite machine tools have an online detection function, so that online detection and precision control of key data in the manufacturing process can be realized, and the processing precision of products is improved; in addition, the high-strength integrated lathe bed design is adopted, and the processing capacity of difficult-to-cut materials is improved.
In some embodiments, the machining device used in the examples of the present application is a turn-milling compound machine tool having a main spindle, a sub-main spindle, and a B-axis.
The B axis of the turning and milling composite machine tool is a servo axis rotating around the Y axis and is a tool rotating shaft with indexing positioning and linkage functions.
The B shaft is matched with other shafts to realize the multi-shaft linkage function of the machine tool, not only can drill inclined holes or mill inclined planes, but also can be used as an interpolation shaft to finish the processing of complex space curved surfaces, and has absolute advantages for processing high-precision complex workpieces. When a workpiece needs to be turned and bored or drilled, tapped, grooved or milled at a certain angle, the indexing positioning function of the B axis is needed, and locking can be required after indexing, otherwise, the cutting force can cause vibration or displacement, thereby affecting the machining precision. The B-axis fixation is generally divided into fixed angle fixation and arbitrary angle fixation. Therefore, the B shaft is provided with two sets of locking mechanisms, one set is locked at a fixed angle (generally 2.5 degrees or integral multiple of 5 degrees), and the other set is locked at any angle. The fixed angle locking is used for meeting the requirements of strong turning, milling and the like on a specified angle plane; the locking at any angle is used for realizing the processing requirement at any angle.
In step S1, rough turning is performed on the air intake side of the blank to remove the large allowance on the air intake side and reserve a process table at the hub of the air intake side of the blank, which may include:
and the auxiliary main shaft of the turning and milling composite machine tool is abutted against the end face of the air outlet side of the blank, and the excircle of the blank is held tightly by three claws to realize the first clamping of the blank.
After the first clamping is completed, roughly turning the air inlet side of the blank to remove the large allowance of the air inlet side and reserving a process table at the hub of the air inlet side of the blank.
Referring to fig. 3, in a specific application, after rough turning of the air inlet side, 2mm of margin may be left at the blade of the blank, 4mm of margin may be left at the process table, and 1.5mm of margin may be left at the rest.
Referring to fig. 4, fig. 4 is a schematic structural diagram of a blank after angular groove milling according to an embodiment of the present application.
In the step S1, milling the air inlet side hub of the blank to form an angular groove, and using the angular groove as an angular reference may include:
