Description

Technical Field

[0001] The present application relates to the technical field of workpiece processing and transfer, and in particular to a workbench transfer device for processing titanium alloy aviation thin-walled parts. Background Art

[0002] In the field of aviation manufacturing, titanium alloy thin-walled parts are widely used in the processing of aerospace structural parts due to their light weight and high strength. However, due to the high hardness of the titanium alloy material itself, a large amount of heat and debris are easily generated during the processing process, especially when processing thin-walled parts, the workpiece is easy to deform, and the accumulation of debris will affect the processing accuracy and efficiency. At the same time, in the actual processing process, it is necessary to manually clamp the workbench on the transfer device and then move it to the machine tool for processing. During the processing, the transfer device cannot be separated from the workbench. After the processing is completed, the new workbench has to spend time on the transfer device for clamping, and at this time the vertical machine tool is idle, and the processing efficiency is low. Summary of the invention

[0003] In order to improve the utilization rate of equipment and enhance processing efficiency and precision, the present application provides a workbench transfer device for processing titanium alloy aviation thin-walled parts.

[0004] The present application provides a worktable transfer device for machining titanium alloy aviation thin-walled parts, which adopts the following technical solution: A workbench transfer device for machining titanium alloy aviation thin-walled parts, comprising a moving seat, on which two working arms are rotatably arranged, on which a clamping assembly is arranged, and the two clamping assemblies are used to clamp the workbench together, on which a rotating assembly is arranged, and the rotating assembly is used to control the rotation of the working arms, and on which a propulsion assembly is also arranged; It also includes a preparation station seat and a processing station seat, the preparation station seat is placed horizontally, the processing station seat is placed vertically, the processing machine tool is directly opposite to the processing station seat, and the processing station seat and the preparation station seat are both provided with a positioning and fixing component, and the positioning and fixing component is used to ensure that the workbench is fixed on the processing station seat / the preparation station seat at the same position each time; The propulsion assembly is used to push the workbench in a vertical state toward the processing station seat.

[0005] By adopting the above technical solution, by vertically fixing the workbench on the processing station seat, the vertical processing method enables the cutting fluid to more fully flush the workpiece surface, which is conducive to the timely discharge of debris, reduces the accumulation of debris, and thus reduces the impact on processing accuracy. It is particularly suitable for the processing of titanium alloy thin-walled parts with complex cavities.

[0006] Due to the setting of the preparation station seat and the processing station seat, workers can complete the clamping preparation work of the next workbench and workpiece on the preparation station seat during the processing. After the processing is completed, the next workbench is immediately transferred to the processing station. The design of two stations can avoid the idle state of the processing machine tool, improve the utilization rate of the equipment, and thus improve production efficiency.

[0007] The preparation station seat and the processing station seat are both equipped with the same positioning and fixing components, which can ensure that the positioning positions of the workbench on the preparation station seat and the processing station seat are completely consistent. After the workbench is moved to the processing station, no manual secondary calibration is required. In this way, it is only necessary to ensure that the workpiece is debugged on the workbench and that the position deviation of the workpiece is within the processing allowance range. Workers only need to perform installation work at the preparation station seat, which reduces the difficulty of operation. This saves workers' operating time and can also reserve time for workers to transfer processed workpieces, further improving production efficiency.

[0008] Optionally, it also includes a slide rail, the movable seat is slidably set on the slide rail, and the movable seat is provided with a driving component for driving it along the slide rail. The processing station seat and the preparation station seat are arranged along one side of the slide rail, and the processing machine tool is located on the other side of the slide rail.

[0009] By adopting the above technical solution, the preparation station and the processing station are arranged along one side of the slide rail, and the processing machine tool is set on the other side of the slide rail. This layout makes full use of the space and reduces the distance that the workbench needs to transfer between different stations, thereby optimizing the overall space utilization of the equipment and reducing the equipment footprint.

[0010] Optionally, the positioning and fixing assembly includes a plurality of zero-point locators, and the workbench is provided with pins corresponding to the zero-point locators one by one, and the zero-point locators on the processing station seat and the zero-point locators on the preparation station seat are arranged in the same manner.

[0011] By adopting the above technical solution, the zero point locator corresponds to the pin on the workbench one by one, ensuring that the workbench can be accurately aligned on the preparation station seat and the processing station seat, and the reliability of repeated positioning is high. There is no need to worry about the workbench requiring additional adjustments due to different clamping methods on the preparation station seat and the processing station seat, and accurate docking and fixation can be completed in a short time, further improving processing preparation and production efficiency.

[0012] Optionally, it also includes a finished product station seat, which is placed horizontally, and the finished product station seat, the preparation station seat and the processing station seat are arranged along the moving direction of the moving seat.

[0013] By adopting the above technical solution, the finished product station seat and other stations are arranged along the moving direction of the moving seat. After the workpiece is processed, it can be directly transferred from the processing station seat to the finished product station seat without additional handling operations. This sequential arrangement design reduces the repeated handling of workpieces between different processes.

[0014] Optionally, the propulsion assembly corresponds one-to-one with the working arm, and the propulsion assembly includes a propulsion cylinder and a moving block, the moving block is slidably connected to the moving seat, the working arm is hinged to the moving block, the propulsion cylinder is installed on the moving seat, the propulsion cylinder is connected to the moving block, and the rotating assembly is arranged on the moving block.

[0015] By adopting the above technical solution, the propulsion cylinder drives the moving block to move, and the moving block can simultaneously drive the rotating component and the working arm to move, thereby realizing the movement of the workbench, and the structure is simple.

[0016] Optionally, the rotating assembly includes a rotating cylinder, which is hinged on the moving block. The piston rod of the rotating cylinder is hinged to the working arm. The hinge axis between the rotating cylinder and the moving block and the hinge axis between the working arm and the moving block are staggered. The moving block is provided with a limiting protrusion, and the working arm is in a vertical state and is in contact with the limiting protrusion.

[0017] By adopting the above technical solution, the piston rod of the rotating cylinder is extended and retracted to drive the working arm to flip. The structure is simple, and the limiting protrusion can stop the working arm from flipping after flipping to a vertical state, thereby avoiding excessive extension of the rotating cylinder, which leads to the inability to drive the working arm to flip and reset.

[0018] Optionally, at least two support columns are further included, wherein the support columns are arranged on a side of the preparatory station seat facing the movable seat, and when the movable seat is aligned with the preparatory station seat, the bottom of the movable seat just contacts with the tops of all the support columns.

[0019] By adopting the above technical solution, when clamping the workbench, the thrust cylinder needs to push the moving block to move close to the preparation station seat, and then the rotating cylinder drives the working arm to flip and clamp. When flipping the working arm to a vertical state, the support column always abuts against the moving seat to prevent the moving seat from tipping over.

[0020] Optionally, the clamping assembly includes a clamping cylinder, which is arranged on the working arm. The piston rod of the clamping cylinder is connected to a connecting plate, and the connecting plate is connected to a plug-in column. The plug-in column and the workbench are provided with fixing holes on both sides, and the plug-in column can be inserted into the corresponding fixing hole on the same side.

[0021] By adopting the above technical solution, the clamping cylinder drives the connecting plate to move, that is, the plug-in column can be inserted into the fixing hole, thereby realizing the clamping of the workstation.

A guide groove is provided on the working arm, and a guide plate is provided on the plug-in column, and the guide plate corresponds one-to-one to and fits with the guide groove.

[0023] By adopting the above technical solution, the guide plate and the guide groove provide a guiding function for the plug-in column, so that the plug-in column moves more smoothly. The design of the tapered hole is conducive to the plug-in column being tightly inserted into the workbench, thereby improving the clamping stability.

[0024] Optionally, a plurality of telescopic tubes are provided on the moving block, the plurality of telescopic tubes are commonly connected to a lifting block, the lifting block is connected to a linkage plate, the moving block is connected to a lifting cylinder, the piston rod of the lifting cylinder is connected to the linkage plate, the cylinder body of the lifting cylinder is connected to the moving block, and the rotating assembly and the working arm are both provided on the lifting block.

[0025] By adopting the above technical solution, when the working arm is in a horizontal state and clamps the workbench, the lifting cylinder is started first, and the lifting cylinder drives the lifting block to rise, so that all the pins are disengaged from the zero point locator, and then flipped, to avoid the situation where the pins are tilted and stuck in the zero point locator during the flipping process.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By fixing the workbench vertically on the processing station seat, the vertical processing method enables the cutting fluid to more fully flush the workpiece surface, which is conducive to the timely discharge of debris, reduces the accumulation of debris, and thus reduces the impact on processing accuracy. It is particularly suitable for the processing of titanium alloy thin-walled parts with complex cavities; 2. Due to the setting of the preparation station seat and the processing station seat, workers can complete the clamping preparation work of the next workbench and workpiece on the preparation station seat during the processing.

In this way, it is only necessary to ensure that the workpiece is debugged on the workbench and that the position deviation of the workpiece is within the processing allowance range.

[0035] The following is combined with Figure 1-7 This application is described in further detail.

[0036] Example 1 The embodiment of the present application discloses a workbench transfer device for machining titanium alloy aviation thin-walled parts.

[0037] like Figure 1 The workbench transfer device for processing titanium alloy aviation thin-walled parts includes a preparation station seat 11, a finished product station seat 12, a processing station seat 13 and a slide rail 14. The preparation station seat 11, the finished product station seat 12 and the processing station seat 13 are located on one side of the slide rail 14, and the three are arranged along the length direction of the slide rail 14. A vertical processing machine 2 is arranged on the other side of the slide rail 14, and the vertical processing machine 2 is directly opposite to the processing station seat 13. The processing station seat 13 is placed vertically, and the preparation station seat 11 and the finished product station seat 12 are placed horizontally. A positioning and fixing component 3 is provided on both the processing station seat 13 and the preparation station seat 11, and the positioning and fixing component 3 is used to ensure that the workbench is fixed on the processing station seat 13 / preparation station seat 11 in the same position each time. The bottom surface area of ​​the workbench is the same as the top surface area of ​​the preparation station seat 11.

[0038] like Figure 1 , Figure 2 and Figure 3 A moving seat 4 is slidably arranged on the slide rail 14, and a driving assembly 6 for driving the moving seat 4 along the slide rail 14 is arranged on the moving seat 4. The driving assembly 6 is installed at the center of the moving seat 4. A propulsion assembly 7 is arranged at both ends of the moving seat 4. A working arm 5 and a rotating assembly 8 are hinged on the propulsion assembly 7. The rotating assembly 8 is used to control the rotation of the working arm 5. A clamping assembly 9 is also arranged on the working arm 5. The inner distance between the two working arms 5 is greater than the width of the workbench.

[0039] During processing, the worker first hoists the workbench and cooperates with the positioning and fixing component 3 to fix the workbench on the preparatory station seat 11, then installs the workpiece on the workbench, the driving component 6 drives the moving seat 4 to move and align with the preparatory station seat 11, and the propulsion component 7 drives the working arm 5 to move in the direction close to the preparatory station seat 11. Then the rotating component 8 controls the working arm 5 to swing to a horizontal state, so that the workbench is located between the two working arms 5, and then the clamping component 9 clamps the workbench, and the rotating component 8 controls the working arm 5 to rotate, so that the working arm 5 and the workbench swing to a vertical state. The propulsion component 7 then drives the working arm 5 to move to the end center of the moving seat 4, and the moving seat 4 moves to the processing station seat 13. The propulsion component 7 pushes the working arm 5 to move, and the workbench approaches the processing station seat 13. The positioning and fixing component 3 automatically fixes the workbench, and then processing can begin. During the processing process, it usually takes several hours. At this time, the worker can transfer the new workbench to the preparatory station seat 11 and fix the next workpiece. After the workpiece on the processing station seat 13 is processed, the workbench with the processed workpiece is first transferred to the finished product station seat 12, and then moved to the preparation station seat 11 to clamp the next workbench.

[0040] By fixing the workbench vertically on the processing station seat 13, the vertical processing method enables the cutting fluid to more fully flush the workpiece surface, facilitates the timely discharge of debris, reduces debris accumulation, and thus reduces the impact on processing accuracy. It is particularly suitable for the processing of titanium alloy thin-walled parts with complex cavities.

[0041] Due to the arrangement of the preparation station seat 11 and the processing station seat 13, the worker can complete the clamping preparation work of the next workbench and the workpiece on the preparation station seat 11 during the processing. After the processing is completed, the next workbench is immediately transferred to the processing station. The design of two station seats can avoid the idle state of the processing machine tool, improve the utilization rate of the equipment, and thus improve the production efficiency.

[0042] The preparation station seat 11 and the processing station seat 13 are both provided with the same positioning and fixing components 3, which can ensure that the positioning positions of the workbench on the preparation station seat 11 and the processing station seat 13 are completely consistent. After the workbench is moved to the processing station seat 13, no manual secondary calibration is required. In this way, it is only necessary to ensure that the workpiece is debugged on the workbench and that the position deviation of the workpiece is within the processing allowance range. The workers only need to perform installation work at the preparation station seat 11, which reduces the difficulty of operation, saves the workers' operating time, and reserves time for the workers to transfer the processed workpieces, further improving production efficiency.

[0043] like Figure 1 and Figure 4The positioning and fixing assembly 3 includes a plurality of zero point positioners 31, and a latch 32 corresponding to the zero point positioners 31 is arranged on the workbench. The zero point positioners 31 on the processing station seat 13 and the zero point positioners 31 on the preparation station seat 11 are arranged in the same manner.

[0044] like Figure 2 and Figure 3 The propulsion assembly 7 includes a propulsion cylinder 71 and a moving block 72. The moving block 72 is slidably connected to the moving seat 4. The working arm 5 is hinged to the moving block 72. The propulsion cylinder 71 is installed on the moving seat 4. The piston rod of the propulsion cylinder 71 is set toward the preparation station seat 11 and can be moved in a direction close to the preparation station seat 11. The moving block 72 is located above the propulsion cylinder 71 and is fixed to the piston rod of the propulsion cylinder 71.

[0045] The rotating assembly 8 is arranged on the moving block 72, and the rotating assembly 8 includes a rotating cylinder 81, which is hinged on the moving block 72, and the piston rod of the rotating cylinder 81 is hinged to the working arm 5. The hinge axis of the rotating cylinder 81 and the moving block 72 and the hinge axis of the working arm 5 and the moving block 72 are staggered, and the hinge axis of the rotating cylinder 81 and the moving block 72 is located below the hinge axis of the working arm 5 and the moving block 72. The hinge axis of the rotating cylinder 81 and the moving block 72 is closer to the preparatory workstation seat 11 than the hinge axis of the working arm 5 and the moving block 72. When the working arm 5 is in a horizontal state, the piston rod of the rotating cylinder 81 is completely retracted into the cylinder body, that is, the piston rod of the rotating cylinder 81 is in the shortest extension state at this time, and the hinge axis of the rotating cylinder 81 and the working arm 5 and the hinge displacement of the working arm 5 and the moving block 72 are on the horizontal line at the same time.

[0046] A limiting protrusion 82 is provided at one end of the moving block 72 away from the preparatory station seat 11, and the working arm 5 is in a vertical state and just abuts against the limiting protrusion 82. Two support columns 83 are installed between the preparatory station seat 11 and the slide rail 14, and the two support columns 83 are each flush with one side of the preparatory station seat 11. When the moving seat 4 is aligned with the preparatory station seat 11, the bottom of the moving seat 4 just contacts the top of the support column 83.

[0047] The thrust cylinder 71 drives the moving block 72 to move, and the moving block 72 can drive the rotating cylinder 81 and the working arm 5 to move at the same time. The piston rod of the rotating cylinder 81 is extended and retracted to drive the working arm 5 to flip. The structure is simple, and the limiting protrusion 82 can stop the flipping of the working arm 5 after it is flipped to a vertical state, thereby avoiding the rotating cylinder 81 from extending too much and failing to drive the working arm 5 to flip and reset.

[0048] Furthermore, when clamping the workbench, the thrust cylinder 71 needs to push the moving block 72 to move closer to the preparation station seat 11, and then the rotating cylinder 81 drives the working arm 5 to flip over and clamp. In this case, when the working arm 5 is flipped to a vertical state, the support column 83 always abuts against the moving seat 4 to prevent the moving seat 4 from tipping over.

[0049] like Figure 2 and Figure 4 The clamping assembly 9 includes a clamping cylinder 91, which is inserted and fixed in the working arm 5. The piston rod of the clamping cylinder 91 can extend from the side of the working arm 5 away from the workbench. The piston rod of the clamping cylinder 91 is connected to a connecting plate 92, and the center of the connecting plate 92 is connected to the piston rod of the clamping cylinder 91. The two ends of the connecting plate 92 are connected to plug-in columns 93, which pass through the working arm 5. Two guide plates 94 are arranged on the circumference of the working arm 5, and the working arm 5 is provided with a guide groove 51 adapted to the guide plate 94. Fixing holes 15 are provided on both sides of the workbench. When the working arm 5 is in a horizontal state and the workbench is completely located between the two working arms 5, the plug-in columns 93 correspond to the fixing holes 15 one by one, and the fixing holes 15 are tapered holes.

[0050] The clamping cylinder 91 drives the connecting plate 92 to move, so that the plug-in column 93 can be inserted into the fixing hole 15, thereby realizing the clamping of the workbench. The guide plate 94 and the guide groove 51 provide a guiding function for the plug-in column 93, so that the plug-in column 93 moves more smoothly. The design of the tapered hole is conducive to the plug-in column 93 being tightly inserted into the workbench, thereby improving the clamping stability.

[0051] like Figure 1 , Figure 5 and Figure 6 The driving assembly 6 includes a driving motor 61, which is installed at the center of the moving seat 4. The slide rail 14 is provided with a rack 62 along its length. The bottom of the moving seat 4 is rotatably connected with a gear 63. The driving motor 61 is coaxially connected with the gear 63, and the gear 63 is meshed with the rack 62. The driving motor 61 drives the gear 63 to rotate, so that the moving seat 4 can move along the slide rail 14.

[0052] The implementation principle of the embodiment of the present application is as follows: during processing, the worker first hoists the workbench and cooperates with the positioning and fixing component 3 to fix the workbench on the preparatory station seat 11, and then installs the workpiece on the workbench, the driving component 6 drives the moving seat 4 to move and align with the preparatory station seat 11, and the pushing component 7 drives the working arm 5 to move in the direction close to the preparatory station seat 11. Then the rotating component 8 controls the working arm 5 to swing to a horizontal state, so that the workbench is located between the two working arms 5, and then the clamping component 9 clamps the workbench, and the rotating component 8 controls the working arm 5 to rotate, so that the working arm 5 and the workbench swing to a vertical state. The pushing component 7 then drives the working arm 5 to move to the end center of the moving seat 4, and the moving seat 4 moves to the processing station seat 13, and the pushing component 7 pushes the working arm 5 to move, and the workbench is close to the processing station seat 13, and the positioning and fixing component 3 automatically fixes the workbench, and then processing can begin. During the processing process, it usually takes several hours, at which time the worker can transfer the new workbench to the preparatory station seat 11 and fix the next workpiece. After the workpiece on the processing station seat 13 is processed, the workbench on which the workpiece has been processed is first transferred to the finished product station seat 12, and then moved to the preparation station seat 11 to clamp the next workbench.

[0053] Example 2 Reference Figure 7 The difference between this embodiment and embodiment 1 is that a plurality of telescopic tubes 73 are provided on the moving block 72, the plurality of telescopic tubes 73 are commonly connected to a lifting block 74, the lifting block 74 is connected to a linkage plate 75, the moving block 72 is connected to a lifting cylinder 76, the piston rod of the lifting cylinder 76 is connected to the linkage plate 75, the cylinder body of the lifting cylinder 76 is connected to the moving block 72, and the rotating cylinder 81 and the working arm 5 are both hinged on the lifting block 74.

[0054] When the working arm 5 is in a horizontal state and clamps the workbench, the lifting cylinder 76 is started first, and the lifting cylinder 76 drives the lifting block 74 to rise, so that all the pins 32 are disengaged from the zero point locator 31, and then flipped to avoid the situation where the pins 32 are tilted and stuck in the zero point locator 31 during the flipping process.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
