Description

Technical Field

[0001] The invention belongs to the technical field of manufacturing parts of aviation engines, and in particular relates to a zero-point quick-change tooling for thin-walled annular parts with the functions of collecting and discharging cutting waste liquid. Background Art

[0002] Components such as the rectifier outer ring, guide window inner and outer rings in aircraft engines are all typical thin-walled annular parts. Such thin-walled annular parts generally have the problems of poor rigidity and great manufacturing difficulty.

[0003] At present, such thin-walled ring parts usually need to go through rough turning, heat treatment or surface treatment, fine turning and milling processes. Not only are the process routes similar, but also the parts between different models are similar, so they are suitable for mass production. Therefore, such parts are often selected for pilot construction of lean units and automated production lines. In this process, in order to improve the efficiency of changeover, designing zero-point quick-change tooling suitable for thin-walled ring parts becomes the key.

[0004] At present, the traditional zero-point positioning tooling suitable for thin-walled ring parts has achieved certain results in achieving rapid positioning and reducing clamping time. However, in actual mass production, it was found that during the transportation of thin-walled ring parts, cutting waste fluid will inevitably remain on the surface of the zero-point quick-change tooling and thin-walled ring parts. These residual cutting waste fluids are very easy to drip onto the robotic arms or other transfer equipment of the automated production line, which will not only have an adverse effect on the cleaning and maintenance of these equipment, but may also cause certain safety hazards. In addition, equipment cleaning and maintenance require production time, which will also reduce production efficiency to a certain extent. Summary of the invention

[0031] In this embodiment, the number of workpiece pads 16 is twelve, the number of workpiece pressure plates 15 is six, the six workpiece pressure plates 15 are used in conjunction with six of the workpiece pads 16, and the six workpiece pads 16 without the workpiece pressure plates 15 and the six workpiece pads 16 with the workpiece pressure plates 15 are alternately arranged in the circumferential direction; the height origin reference block 17 located on the outside of the workpiece pad 16 is arranged adjacent to one of the workpiece pads 16 without the workpiece pressure plate 15; the number of workpiece height lifting adjustment mechanisms 18 is four sets, the angle between any two adjacent sets of the four sets of workpiece height lifting adjustment mechanisms 18 is 90°, and the control rod of each set of workpiece height lifting adjustment mechanisms 18 passes through between two adjacent workpiece pads 16.

[0032] The following describes a one-time use process of the present invention in conjunction with the accompanying drawings: When the thin-walled annular parts are positioned and clamped above the zero-point quick-change tooling sub-disk 2 by the thin-walled annular parts fixture, quick replacement can be achieved. During quick replacement, the thin-walled annular parts can be transported over long distances through the transfer lugs 14, and can be transported over short distances by using the sub-disk transfer guide slider 12 and the sub-disk transfer guide rail 11 in combination.

[0033] When the zero-point quick-change tooling sub-disc 2 with thin-walled annular parts positioned and clamped is transferred to the top of the zero-point quick-change tooling mother disk 1, the guide positioning pin mechanism 4 can realize the rapid and accurate positioning of the zero-point quick-change tooling sub-disc 2 and the zero-point quick-change tooling mother disk 1, and then the pneumatic rivet locking positioning mechanism 3 is adjusted to the locking state in an air-controlled manner to realize the fastening assembly of the zero-point quick-change tooling sub-disc 2 and the zero-point quick-change tooling mother disk 1.

[0034] After the zero-point quick-change tooling sub-disk 2 and the zero-point quick-change tooling mother disk 1 are fastened and assembled, as the zero-point quick-change tooling sub-disk 2 is pulled down and locked by the pneumatic rivet locking and positioning mechanism 3, a relative displacement will occur between the drainage trigger push rod 10 and the zero-point quick-change tooling sub-disk 2, but the spring self-closing sealing plug 9 will be blocked by the drainage trigger push rod 10, resulting in no relative displacement between the spring self-closing sealing plug 9 and the drainage trigger push rod 10. At this time, the spring self-closing sealing plug 9 releases the blockage of the drainage port, thereby realizing the conduction of the drainage port.

[0035] During the processing of thin-walled annular parts, the generated cutting waste fluid will first flow into the liquid collecting groove 5, and then will flow to the liquid inlet along the liquid collecting groove 5, and then flow into the liquid storage chamber 7 through the liquid inlet. Due to the presence of the filter screen 6, the cutting impurities entrained in the cutting waste fluid will be blocked above the filter screen 6, ensuring that the cutting waste fluid flowing into the liquid storage chamber 7 can flow efficiently and avoid blockage caused by the presence of cutting impurities. After the cutting waste fluid flows into the liquid storage chamber 7, it will further flow out of the zero-point quick-change tooling sub-disk 2 through the drain port, and finally flow into the cutting waste fluid discharge system of the machine tool.

[0036] When the thin-walled annular part needs to be quickly replaced after the processing of this process is completed, first release the pneumatic rivet locking and positioning mechanism 3 to release the pull-down lock on the zero-point quick-change tooling sub-disc 2, thereby releasing the fastened connection state between the zero-point quick-change tooling sub-disc 2 and the zero-point quick-change tooling mother disk 1, and then the zero-point quick-change tooling sub-disc 2 can be separated from the zero-point quick-change tooling mother disk 1. During the separation process, the spring self-closing sealing plug 9 is out of contact with the drainage trigger push rod 10. As the resistance of the drainage trigger push rod 10 to the spring self-closing sealing plug 9 disappears, the spring self-closing sealing plug 9 is reset under the action of its own spring force. , and finally restore the spring self-closing sealing plug 9 to the drainage port. At this time, the cutting waste liquid remaining in the liquid storage chamber 7 can no longer flow out through the drainage port and can only be temporarily sealed in the liquid storage chamber 7. At this time, during the transportation of thin-walled annular parts, no cutting waste liquid can flow out, thereby effectively avoiding the cutting waste liquid from dripping on the robot arm or other transportation equipment of the automated production line, thereby reducing the frequency and difficulty of cleaning and maintenance of the equipment, and further reducing the occupancy rate of equipment cleaning and maintenance on production time, so that production efficiency is further improved, and at the same time, it also effectively avoids the safety hazards caused by cutting waste liquid dripping on the equipment.

[0037] When the zero-point quick-change tooling sub-disc 2 and the zero-point quick-change tooling mother disk 1 of the next process are fastened and assembled, the spring self-closing sealing plug 9 will be automatically lifted up by the drainage trigger push rod 10 at the process, and the cutting waste fluid temporarily sealed in the liquid storage chamber 7 will be automatically discharged through the conductive drainage hole. At the same time, the drainage hole in the conductive state will continue to be used to discharge the cutting waste fluid generated in this process.

[0038] The solutions in the embodiments are not intended to limit the protection scope of the present invention. All equivalent implementations or changes that do not deviate from the present invention are included in the protection scope of the present invention.
