Description

Technical Field

[0001] This invention belongs to the field of aero-engine compressor rotor blade processing technology, and relates to vibration marking processing of tenons of aero-engine compressor rotor blades, and particularly relates to a vibration marking processing system and method for rotor blades. Background Technology

[0002] As attached Figure 1 As shown, a certain type of aero-engine compressor rotor blade mainly includes a blade body 100, a rim plate 200, and tenons 300. The rim plate 200 and tenons 300 constitute the tenon of the blade. Currently, in the on-site processing of rotor blades, positioning blocks are typically used to fix the blade, and the position of the positioning blocks is manually adjusted to achieve vibration marking of the blade tenon. Since the vibration marking of the blade tenon involves marking two positions—the end face and the top face of the tenon—the positioning blocks need to be adjusted twice during the processing. Specifically, after the operator marks one position, the position of the positioning blocks is adjusted to batch-mark another position, ultimately achieving vibration marking of the blade tenon at the designed position. During the vibration marking process, the operator needs to repeatedly adjust the position of the positioning blocks to adjust the position of the blade tenon, resulting in high labor intensity and poor consistency in marking results, easily leading to incorrect or missed markings.

[0003] With the increasing quality requirements and production volume of aero-engine compressor rotor blades, the existing vibration marking processing method is difficult to guarantee the processing quality and efficiency of the blades. There is an urgent need to find a vibration marking processing technology to replace the manual placement of positioning blocks for blade tenons, so as to realize the transformation of blade tenon vibration marking processing to an automated, standardized and unmanned method.

[0051] The first moving device, the second moving device, and the third moving device all employ multi-axis robotic arms.

[0052] Both the first and second material warehouses utilize automated pallet storage systems; as shown in the attached diagram. Figure 4 As shown, the three-dimensional pallet storage includes a cuboid frame 11, several layers of pallet plates 12, and an outer protective cover 13. The several layers of pallet plates 12 are arranged vertically within the cuboid frame 11. Each pallet plate 12 is provided with several pallet storage positions 14, which are used to store positioning block fixtures that clamp part positioning blocks. The outer protective cover 13 covers the outside of the cuboid frame.

[0053] It should be noted that the three-dimensional pallet storage is fixed to the ground and used for the classified storage of blanks, parts, and tooling. Preferably, the three-dimensional pallet storage is designed with 5 layers of pallets, and the cuboid frame is assembled from vertical and horizontal beams and crossbeams located between the horizontal beams.

The vibration marking machine is equipped with an Ethernet port, USB, RS232 / 485, and I / O interface. Specifically, it can communicate with a multi-axis robot through the I / O interface.

It can also communicate with the main control unit through the Ethernet port to receive the marking part information sent by the main control unit and provide feedback on the marking status and the working status of the marking machine.

[0055] The main control unit is connected to the first moving device, the second moving device, the third moving device, the vibration marking machine, and the part detection sensor. The main control unit is used to read part marking information of the rotor blades from the data storage chip, generate and send vibration marking action commands to the vibration marking machine. The vibration marking action commands trigger the vibration marking machine to perform multi-directional vibration marking of the tenons on the rotor blades to be marked. The main control unit is also used to send part transfer action commands to the first moving device, the second moving device, and the third moving device based on the feedback information from the part detection sensor and the vibration marking machine. The part transfer action commands trigger the first moving device, the second moving device, or the third moving device to perform the action of transferring a positioning block clamp containing a part positioning block.

[0056] Working principle and processing method:

[0057] The vibration marking processing system for rotor blades described in this invention, in use, firstly assembles the part positioning block with the rotor blade to be marked into the positioning block fixture; then, using a first moving device, the positioning block fixture with the part positioning block is transferred to a first material library to await marking processing; using a second moving device, the positioning block fixture with the part positioning block is transferred from the first material library to the preset marking station of the vibration marking machine; the vibration marking machine performs multi-directional vibration marking of the tenon on the rotor blade to be marked according to the part marking information of the rotor blade; after the tenon vibration marking operation is completed, using a third moving device, the positioning block fixture with the part positioning block is transferred to a second material library for storage.

[0058] Specifically, taking the vibration marking process of a compressor rotor blade of an aero-engine using the above-mentioned vibration marking processing system for rotor blades as an example; wherein, the rotor blade to be marked is a precision forging part, and the material is GH4169; the blade body size of the rotor blade to be marked has been completed by precision forging forming process, and the tenon, air inlet edge and exhaust edge of the rotor blade to be marked are each reserved with a 2mm machining allowance.

[0059] The vibration marking process specifically includes the following steps:

[0060] Step 1: Using the alloy casting method, fix the rotor blade to be marked in the part positioning block. Specifically, according to the preset feature points of the rotor blade to be marked, position and assemble the rotor blade to be marked in the positioning block casting fixture; after the rotor blade to be marked is positioned in the positioning block casting fixture, pour in molten alloy, and after cooling, obtain the part positioning block with the rotor blade to be marked fixed.

[0061] It should be noted that during the positioning and assembly process of the rotor blade to be marked, three feature points on the blade head are used for positioning, one feature point on the blade back is used for clamping, two feature points on the inlet side are used for positioning, one feature point on the exhaust side is used for clamping, and one feature point on the flange surface is used for positioning. This achieves six degrees of freedom positioning and fixing of the rotor blade to be marked, ensuring the uniqueness of the positioning position of the rotor blade in the positioning block casting fixture, thereby transferring the positioning reference of the rotor blade to be marked to the part positioning block; the alloy melt is a molten alloy material with a melting point lower than that of the rotor blade to be marked.

[0062] In this invention, the part positioning block is cast from an alloy melt with a melting point lower than that of the rotor blade to be marked. The overall structure is cuboid. When performing multi-directional vibration marking of the rotor blade to be marked, the part positioning block is positioned and clamped in the X, Y and Z axes. The part positioning block is used to convert the positioning reference of the rotor blade to be marked, which is precision forged, to effectively prevent deformation caused by directly clamping the small rotor blade, thus ensuring the accuracy of vibration marking and the product quality of the rotor blade.

[0063] Step 2: Clamp the part positioning block with the rotor blade to be marked in the positioning block fixture to obtain the positioning block fixture with the part positioning block; wherein, the repeated clamping error of the same part positioning block in the same positioning fixture is less than 0.005mm, and the consistent clamping error of the same part positioning block in different fixtures is less than 0.01mm; the positioning block fixture is easy to operate, the clamping structure is safe and reliable, avoiding damage to the part positioning block and the rotor blade it covers, and has good positioning accuracy, meeting the blade processing accuracy requirements; it should be noted that each positioning block fixture should be clearly marked with the tooling number and blade part number, have automatic identification and visual identification capabilities, have error prevention function, the fixture surface is rust-proofed, and the edges are free of sharp edges and burrs.

[0064] Step 2: Using the first moving device, transfer the positioning block fixture containing the part positioning block to the first material warehouse to await marking and processing.

[0065] Step 3: Using the second moving device, the positioning block fixture containing the part positioning block in the first material warehouse is transferred to the preset marking station of the vibration marking machine; specifically, the multi-axis movement of the second moving device is used to transfer the positioning block fixture containing the part positioning block in the first material warehouse to the preset marking station of the vibration marking machine, so that the tenon 2 of the rotor blade to be marked is set close to one end of the marking needle of the vibration marking machine.

[0066] Step 4: Using a vibration marking machine, the rotor blades to be marked are marked with multi-directional vibration based on the part marking information of the rotor blades stored in the data storage chip.

[0067] Step 5: After the tenon vibration marking operation is completed, the positioning block fixture with the part positioning block is transferred to the second material warehouse for storage using the third moving device.

[0068] Step 6: Take out the positioning block fixture containing the part positioning block from the second material warehouse, and remove the part positioning block with the rotor blade fixed from the positioning block fixture; then, remove the rotor blade from the part positioning block to obtain the rotor blade after vibration marking processing.

[0069] It should be noted that the main control unit automatically controls the vibration marking machine, the first moving device, the second moving device, and the third moving device by reading the part marking information of the rotor blades from the data storage chip and collecting the feedback data from the part detection sensor, which can achieve 24-hour unattended operation.

[0070] In this invention, considering the structural characteristics of the blade, a vibration marking machine, a moving device, and a positioning block fixture are used to replace manual marking operations, achieving automated and unmanned marking processing of the blade tenons. The positioning block fixture incorporates a fixture tray with an embedded data storage chip to record the marking information of the clamped parts, ensuring the accuracy and uniqueness of the part marking data. The fixture tray is designed using a high-precision quick-change fixture tray. When the part reaches the marking position, the main control unit receives a signal and collects data, directly sending the part marking information to the complete set of the vibration marking machine. At the device site, information collection and transmission are efficient and fast, ensuring the accuracy and efficiency of the marking content; operation is simple and easy to learn, and the marking content can be easily changed, only requiring changes to the part information in the control system; when used in conjunction with a movable device, the contact pressure can be adjusted in a timely manner according to the wear of the marking and engraving needle, thereby ensuring the clarity of the font; by using a multi-axis robotic arm for transfer and precise placement of the tenon marking station, the application of multi-directional vibration marking processing of part tenons can be completed in one go, replacing the multiple placement operations of the part station by the operator during the vibration marking process, reducing the labor intensity of the operator.

[0071] The vibration marking processing system and method described in this invention enables the multi-directional marking processing of tenons after a part has been clamped and positioned once. This simplifies the complicated manual operation process, reduces the labor intensity of personnel, and improves the accuracy and consistency of vibration marking of blade tenons, achieving automated and intelligent vibration marking of blade tenons.

[0072] The above embodiments are merely one of the implementation methods for achieving the technical solution of the present invention. The scope of protection claimed by the present invention is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention.
