Description

Technical Field

[0001] This invention relates to the field of aero-engine manufacturing technology, specifically to a hydraulic lateral pressure plate for processing aero-engine parts. Background Technology

[0002] As a core component of high-end power equipment, aero-engine components have complex geometries and demanding material properties. They are mostly made of high-strength materials such as high-temperature alloys and titanium alloys, and require extremely high machining precision. Positioning errors must be controlled within the micrometer level, directly determining the overall efficiency, reliability, and service life of the aero-engine. In the machining process of aero-engine components, the lateral clamping plate is a key tooling component for achieving precise positioning and stable clamping of the components. Its positioning accuracy and clamping reliability directly affect the dimensional accuracy and surface quality of the components, as well as the stability and efficiency of the machining process.

[0003] Currently, most lateral clamping plates used in the machining of aero-engine components adopt traditional rigid clamping structures or integrated feed and clamping designs with a single hydraulic drive. These designs have many technical shortcomings and are difficult to adapt to the high-precision machining requirements of aero-engine components. Traditional rigid lateral clamping plates rely on bolt locking or simple spring tightening to achieve clamping. Their feed position adjustment depends on manual operation, resulting in low positioning accuracy and an inability to achieve precise and controllable position adjustment. Furthermore, the clamping force is difficult to control evenly, which can easily lead to insecure clamping. This can cause slight displacement of components during machining, resulting in dimensional deviations and even defects such as vibration marks and surface damage, significantly increasing the scrap rate.

[0004] In summary, current lateral clamping plates used for machining aero-engine components generally suffer from problems such as low positioning accuracy, unstable clamping, mutual interference between feeding and clamping, poor ease of reset, high operational difficulty, and insufficient adaptability, making it difficult to meet the actual needs of high-precision and high-efficiency machining of aero-engine components.

[0015] Preferably, the base is provided with a control interface for detecting the electromagnet current and the oil pressure, and the control interface is electrically connected to an external hydraulic control system.

[0016] (III) Beneficial Effects Compared with the prior art, the present invention provides a hydraulic lateral pressure plate for processing aero-engine parts, which has the following advantages: 1. This hydraulic side pressure plate for machining aero-engine components utilizes a hydraulic feed mechanism and a clamping mechanism mounted on a base. The hydraulic feed mechanism, through the cooperation of a sliding cavity, piston, telescopic spring, and a first oil circuit, injects hydraulic oil into the first oil circuit and controls the amount of oil injected to achieve precise adjustment of the piston position, thereby driving the side pressure plate to the designated position. Simultaneously, hydraulic oil is injected into the sealing cavity through a second oil circuit, pushing the clamping plug towards the clamping plate, firmly fixing the side pressure plate between the clamping plug and the clamping plate. When unlocking, the hydraulic oil in the sealing cavity is first discharged to reduce the clamping force, and then the hydraulic oil in the sliding cavity is discharged. The telescopic spring drives the side pressure plate to reset. This achieves precise and controllable feed position of the side pressure plate and stable and reliable clamping state, solving the problems of low positioning accuracy and unstable clamping of traditional side pressure plates. It is suitable for the high-precision machining requirements of aero-engine components, avoids dimensional deviations caused by component displacement during machining, and provides convenient reset, improving machining efficiency, reducing operational difficulty, and ensuring the stability of machining quality.

[0017] 2. This hydraulic side clamping plate for processing aero-engine components utilizes a first oil circuit connecting the sliding chamber hydraulic oil chamber to the first injection port, and a second oil circuit connecting the sealing chamber hydraulic oil chamber to the second injection port. Oil nozzles are connected to the first and second injection ports, and these nozzles are connected to a common electro-hydraulic pump. The hydraulic pump fills the first oil circuit with fluid and controls the filling amount, achieving precise adjustment of the piston extension length, thereby changing the position of the side clamping plate. Then, the hydraulic pump fills the second oil circuit, adjusting the fluid volume in the sealing chamber to change the position of the clamping plug, achieving a firm clamping of the side clamping plate. The achieved results are a simplified hydraulic oil injection and control process, mechanization and precision of side clamping plate position adjustment and clamping actions, eliminating the need for manual adjustment, reducing manual labor intensity, and allowing flexible adjustment of the side clamping plate position according to different sizes and shapes of aero-engine components. This improves the versatility and adaptability of the device, shortens component changeover adjustment time, further improves processing efficiency, and ensures stable hydraulic control, guaranteeing uniform clamping force and preventing deformation of components due to uneven force.

[0018] 3. The hydraulic side clamping plate used for machining aero-engine components, through a controllable connecting adjustment mechanism consisting of an electromagnet, adjusting block, tension spring, and oil passage between the first and second oil circuits, achieves automatic clamping after the side clamping plate is fed into position, and adaptive matching between the extension length and clamping force. When the electromagnet is energized, the adjusting block can be opened to open the oil pressure by setting the current magnitude. Only after the piston is fed into position and the oil pressure in the sliding chamber rises to the preset value will the adjusting block be pushed to open the oil passage, allowing hydraulic oil to enter the second oil circuit to drive the clamping action, thus avoiding clamping before the side clamping plate is in position. This design eliminates problems such as interference and damage to workpieces. The longer the side pressure plate extends, the higher the required feed oil pressure, the greater the corresponding clamping opening pressure, and the higher the oil pressure entering the sealing cavity. Consequently, the clamping force of the clamping plug on the side pressure plate increases, thus automatically achieving adaptive locking with a greater clamping force as the extension length increases. This design can complete the sequential actions of feeding, holding pressure, and clamping without additional solenoid valves, sensors, or complex control programs, improving system response speed and operational stability, reducing control costs and failure points, and achieving the technical effects of reliable action logic, high clamping accuracy, strong safety, and outstanding adaptive capability.

[0019] 4. The hydraulic lateral pressure plate used for machining aero-engine parts, by setting an oil drain hole on the adjusting block and cooperating with the main drain port of the base, uses a tension spring to reset the adjusting block when the electromagnet is de-energized, realizing rapid pressure relief of the second oil circuit and the sealing cavity. At the same time, combined with the piston hinged connector and the side pressure plate swing angle adjustment structure, the limit pin and the waist hole guide limit structure, it realizes the angle adaptive adjustment and rapid clamping and resetting during the side pressure plate clamping process. The side pressure plate can swing around the connecting shaft, which can adapt to the complex curved surface of aero-engine parts and different lateral clamping angles, improving the tooling for clamping irregular parts. Adaptability; the waist hole and limit pin provide guidance and limit during feeding and angle adjustment, preventing the side pressure plate from swaying or moving, and ensuring accurate clamping position; during depressurization, the oil drain hole is directly connected to the main drain port, realizing rapid force release of the clamping mechanism, and with the return of the feed chamber telescopic spring, the clamping time is greatly shortened, and the loading, unloading and changing efficiency is improved; the overall structure has the advantages of adjustable angle, accurate guidance, reliable clamping, rapid depressurization and smooth return, effectively improving the processing and clamping efficiency and ease of use of aero-engine parts, achieving the effect of high clamping flexibility, simple operation, convenient maintenance and strong practicality.

[0020] 5. This hydraulic lateral pressure plate for machining aero-engine parts uses a fixed connector at the end of the piston furthest from the piston head. A connecting shaft is installed inside the connector, and the middle of the lateral pressure plate is hinged to the connecting shaft, allowing the lateral pressure plate to swing and adjust its angle around the connecting shaft. Simultaneously, waist holes are opened on the side plates at both ends of the lateral pressure plate. A clamping plate has through mounting holes and a limit pin is installed. A clamping plug has corresponding fixing holes. The limit pin passes through the waist holes and movably engages with the fixing holes, guiding and limiting the feeding and swinging process of the lateral pressure plate. In the clamped state, the clamping plug and clamping plate lock the lateral pressure plate in place; thus achieving lateral... The flexible adjustment of the pressure plate angle adapts to the processing requirements of different angles of aero-engine parts, solving the problem that the traditional side pressure plate angle is fixed and cannot adapt to the processing of complex curved surfaces or irregular parts. At the same time, the cooperation between the limit pin and the waist hole can effectively limit the swing amplitude and feed trajectory of the side pressure plate, avoid the side pressure plate offset during the adjustment process, ensure positioning accuracy, and the locking structure in the clamping state further improves the clamping stability, prevents the side pressure plate from loosening or offsetting during processing, ensures the dimensional accuracy and surface quality of the parts, and broadens the application range of the device.

[0032] Example 1: This embodiment provides a hydraulic lateral pressure plate for processing aero-engine parts, which has the following technical features.

[0033] Please see Figure 1-5 A hydraulic lateral pressure plate for machining aero-engine parts includes a base 100. A hydraulic feed mechanism 110 and a clamping mechanism 120 are mounted on the base 100. The hydraulic feed mechanism 110 includes a sliding cavity 111 located on one side of the base 100. A piston 112 is slidably and sealed within the sliding cavity 111. A telescopic spring 113 is provided between the piston 112 and the sliding cavity 111. A fixing block 114 is provided at the opening of the sliding cavity 111. The piston 112 passes through the fixing block 114 and is slidably and sealingly engaged with it. The base 100... The base 100 has a first oil passage 101, which is connected to the sliding cavity 111. The clamping mechanism 120 includes a sealing cavity 121 opened in the base 100. A clamping plug 122 is slidably sealed in the sealing cavity 121. A second oil passage 102 is opened in the base 100 and is connected to the sealing cavity 121. A clamping plate 123 is fixed on the base 100. The middle part of the piston 112 is connected to the side pressure plate 130. Both ends of the side pressure plate 130 extend into the space between the clamping plug 122 and the clamping plate 123 to be clamped and positioned.

[0034] It should be noted that by injecting hydraulic oil into the first oil passage 101, and controlling the amount of hydraulic oil injected into the first oil passage 101, the amount of hydraulic oil in the sliding chamber 111 can be changed, thereby controlling the position of the piston 112, and thus changing the side pressure plate 130 to reach the designated position to fix the engine components. At this time, the telescopic spring 113 is in a compressed state. At the same time, by injecting hydraulic oil into the second oil passage 102, because the second oil passage 102 is connected to the sealing chamber 121, when different volumes of hydraulic oil are injected into the second oil passage 102... Hydraulic oil is pumped to push the clamping plug 122 toward the opening of the sealing cavity 121, thereby firmly fixing the side pressure plate 130 between the clamping plug 122 and the clamping plate 123. This facilitates the fixation of engine components by the side pressure plate 130. When it is necessary to remove the fixation, the hydraulic oil inside the sealing cavity 121 is first drained to reduce the clamping force between the clamping plate 123 and the clamping plug 122. Then, the hydraulic oil inside the sliding cavity 111 is drained. When the extension spring 113 returns to its original state, it can drive the side pressure plate 130 back to its original position.

[0035] Preferably, the two ends of the first oil circuit 101 are respectively connected to the hydraulic oil chamber of the sliding cavity 111 and the first injection port, and the two ends of the second oil circuit 102 are respectively connected to the hydraulic oil chamber of the sealing cavity 121 and the second injection port.

[0036] It should be noted that oil nozzles are connected to the first and second injection ports respectively. These nozzles are then connected to a common electro-hydraulic oil pump, allowing hydraulic oil to be injected into either the first oil circuit 101 or the second oil circuit 102 via the pump. First, the first oil circuit 101 is filled with hydraulic oil using the pump. By controlling the amount of hydraulic oil injected, the amount of hydraulic oil inside the sliding chamber 111 can be controlled, thereby changing the extension length of the piston 112 and consequently altering the position reached by the side pressure plate 130. This allows the side pressure plate 130 to adapt to engine parts of different sizes and shapes. Then, by filling the second oil circuit 102 with hydraulic oil pump, the amount of liquid inside the sealing cavity 121 is changed, thereby changing the position of the clamping plug 122 inside the sealing cavity 121. This causes the clamping plug 122 to move towards the clamping plate 123, clamping the side pressure plate 130 between the clamping plug 122 and the clamping plate 123, thus fixing the clamping plate 123 and facilitating the lateral pressing of the engine parts by the side pressure plate 130.

[0037] Further, the electro-hydraulic oil pump is electrically connected to an externally located control center.

[0038] Preferably, a connector 1121 is fixed at the end of the piston 112 away from the piston head, and a connecting shaft 1122 is provided inside the connector 1121. The middle part of the side pressure plate 130 is hinged to the connecting shaft 1122, so that the side pressure plate 130 can swing around the connecting shaft 1122 to adjust the angle.

[0039] It should be noted that by detachably connecting the connecting shaft 1122 to the inside of the connector 1121, and by providing a rotating groove on the connector 1121 for the side pressure plate 130 to rotate around the connecting shaft 1122, the side pressure plate 130 can change its angle according to different engine components when the piston 112 drives the side pressure plate 130 to change its position.

[0040] Preferably, the side plates at both ends of the side pressure plate 130 are provided with waist holes 131, the clamping plate 123 is provided with a through mounting hole, a limit pin 132 is detachably provided in the mounting hole, and the clamping plug 122 is provided with a fixing hole 1221 corresponding to the mounting hole. The limit pin 132 passes through the waist hole 131 and is movably engaged with the fixing hole 1221. The waist hole 131 is used for guiding and limiting the side pressure plate 130 during the feeding and swinging process. In the clamping state, the clamping plug 122 and the clamping plate 123 lock the side pressure plate 130.

[0041] It should be noted that before the clamping plug 122 and the clamping plate 123 are clamped together, when the piston 112 drives the side pressure plate 130 to change position, when the engine parts are set at different angles, the limiting pin 132 can limit the position of the left and right side plates of the side pressure plate 130 when the side pressure plate 130 rotates around the connecting shaft 1122.

[0042] Preferably, a clamping return spring is provided between the clamping plug 122 and the sealing cavity 121. The clamping return spring is used to drive the clamping plug 122 to reset and release the side pressure plate 130 when the second oil circuit 102 is depressurized.

[0043] Preferably, the clamping plug 122 and the clamping plate 123 are provided with anti-slip toothed surfaces or flexible pressing pads on the side facing the side pressure plate 130, and the two ends of the side pressure plate 130 are provided with corresponding pressing mating surfaces.

[0044] Working principle: When the device is working, hydraulic oil is first injected into the first oil circuit 101 through the oil nozzles connected to the first and second injection ports and the electro-hydraulic oil pump. The amount of hydraulic oil injected is controlled to adjust the amount of hydraulic oil in the sliding cavity 111, which pushes the piston 112 to slide in the sliding cavity 111 and compress the telescopic spring 113. The piston 112 drives the end connector 1121 and the connecting shaft 1122 to move synchronously, thereby driving the side pressure plate 130 hinged to the connecting shaft 1122 to feed to the designated position. During the feeding process, the side pressure plate 130 can swing around the connecting shaft 1122 to adjust the angle to adapt to the different angle requirements of the aero-engine parts. At the same time, the limiting pin 132 on the clamping plate 123 passes through the waist hole 131 at both ends of the side pressure plate 130 and cooperates with the fixing hole 1221 of the clamping plug 122 to guide and limit the feeding trajectory and swing amplitude of the side pressure plate 130 to avoid deviation. After the side pressure plate 130 reaches the target position, hydraulic oil is injected into the second oil circuit 102 through the hydraulic oil pump, pushing the clamping plug 122 in the sealing cavity 121 to move towards the clamping plate 123, and firmly locking the side pressure plate 130 between the clamping plug 122 and the clamping plate 123, so as to achieve stable positioning of the side pressure plate 130 for processing of the parts; after processing, the hydraulic oil in the second oil circuit 102 and the sealing cavity 121 is discharged first, the clamping return spring drives the clamping plug 122 to return to its original position, the side pressure plate 130 is released, and then the hydraulic oil in the first oil circuit 101 and the sliding cavity 111 is discharged, the extension spring 113 returns to its original position and drives the piston 112 and the side pressure plate 130 to return to their original position, completing the entire working cycle.

[0045] Example 2: This embodiment provides a hydraulic lateral pressure plate for processing aero-engine parts, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0046] Please see Figure 1-3 and Figure 6A hydraulic lateral pressure plate for machining aero-engine parts includes a base 100. A hydraulic feed mechanism 110 and a clamping mechanism 120 are mounted on the base 100. The hydraulic feed mechanism 110 includes a sliding cavity 111 located on one side of the base 100. A piston 112 is slidably and sealed within the sliding cavity 111. A telescopic spring 113 is provided between the piston 112 and the sliding cavity 111. A fixing block 114 is provided at the opening of the sliding cavity 111. The piston 112 passes through the fixing block 114 and is slidably and sealingly engaged with it. The base 100... The base 100 has a first oil passage 101, which is connected to the sliding cavity 111. The clamping mechanism 120 includes a sealing cavity 121 opened in the base 100. A clamping plug 122 is slidably sealed in the sealing cavity 121. A second oil passage 102 is opened in the base 100 and is connected to the sealing cavity 121. A clamping plate 123 is fixed on the base 100. The middle part of the piston 112 is connected to the side pressure plate 130. Both ends of the side pressure plate 130 extend into the space between the clamping plug 122 and the clamping plate 123 to be clamped and positioned.

[0047] It should be noted that by injecting hydraulic oil into the first oil passage 101, and controlling the amount of hydraulic oil injected into the first oil passage 101, the amount of hydraulic oil in the sliding chamber 111 can be changed, thereby controlling the position of the piston 112, and thus changing the side pressure plate 130 to reach the designated position to fix the engine components. At this time, the telescopic spring 113 is in a compressed state. At the same time, by injecting hydraulic oil into the second oil passage 102, because the second oil passage 102 is connected to the sealing chamber 121, when different volumes of hydraulic oil are injected into the second oil passage 102... Hydraulic oil is pressurized, which pushes the clamping plug 122 toward the opening of the sealing cavity 121, thereby firmly fixing the side pressure plate 130 between the clamping plug 122 and the clamping plate 123. This facilitates the fixation of engine components by the side pressure plate 130. When it is necessary to remove the fixation, the hydraulic oil inside the sealing cavity 121 is first drained, which reduces the clamping force between the clamping plate 123 and the clamping plug 122. Then, the hydraulic oil inside the sliding cavity 111 is drained. When the extension spring 113 returns to its original state, it can drive the side pressure plate 130 back to its original position.

[0048] Preferably, a controllable adjustment mechanism 140 is provided between the first oil passage 101 and the second oil passage 102; The regulating mechanism 140 includes an oil passage 141 that connects the first oil passage 101 and the second oil passage 102, and a pressure relief groove 142 coaxial with the oil passage 141 is provided in the base 100. An electromagnet 143 is fixed at one end of the pressure relief groove 142 away from the oil passage 141. An adjusting block 144 is slidably provided in the pressure relief groove 142. A tension spring 145 is provided between the adjusting block 144 and the electromagnet 143. The adjusting block 144 is used to close the oil passage 141 when the electromagnet 143 is de-energized, and when the electromagnet 143 is energized, it can move against the force of the tension spring 145 after the oil pressure in the first oil passage 101 reaches the preset value, thereby opening the oil passage 141 and making the first oil passage 101 and the second oil passage 102 controllably connected.

[0049] It should be noted that the first oil passages 101 and 102 are connected by an oil passage 141. When hydraulic oil is injected into the first oil passage 101, the hydraulic oil flows into the sliding chamber 111 through the first oil passage 101, compressing the piston 112 and changing its position. Simultaneously, the current on the electromagnet 143 is controlled, thereby controlling the repulsive force of the electromagnet 143 on the adjusting block 144. The current on the electromagnet 143 is adjusted according to the required extension length of the piston 112, thus controlling the adjustment block 144. When the hydraulic pressure inside the sliding cavity 111 is sufficiently high, the hydraulic pressure inside the sliding cavity 111, the first oil passage 101, and the oil passage 141 is equal, thereby causing the adjusting block 144 to move towards the electromagnet 143. This allows the first oil passage 101 and the second oil passage 102 to connect. At this time, when some of the hydraulic oil inside the first oil passage 101 and the sliding cavity 111 flows to the second oil passage 102 and the sealing cavity 121, the hydraulic pressure inside the first oil passage 101 and the sliding cavity 111 decreases. At this point, the tension... The tension of the spring 145 on the adjusting block 144 is less than the repulsive force of the electromagnet 143 on the adjusting block 144, thus the adjusting block 144 re-isolates the connection between the first oil circuit 101 and the second oil circuit 102. At this time, the injection port of the first oil circuit 101 is replenished with fluid. When the above-mentioned hydraulic pressure is replenished, the oil passage 141 reopens, and the hydraulic pressure in the first oil circuit 101 and the sliding cavity 111 is transferred to the second oil circuit 102 and the sealing cavity 121. This process is repeated multiple times until the first oil circuit 101, 102 and the sliding cavity 111 are connected. When the hydraulic pressure inside the sealing cavity 121 is the same as that inside the 111, the side pressure plate 130 has reached the designated position. At the same time, the pressure inside the sealing cavity 121 increases, pushing out the clamping plug 122 and clamping the side pressure plate 130 between the clamping plug 122 and the clamping plate 123. The longer the side pressure plate 130 extends, the easier it is to shake. At this time, the hydraulic pressure inside the sliding cavity 111 and the sealing cavity 121 is greater, the clamping force between the clamping plug 122 and the clamping plate 123 is greater, and the side pressure plate 130 is clamped more firmly. In simple terms, after the electromagnet 143 is energized, the opening pressure of the adjusting block 144 can be set by the magnitude of the current; only when the oil pressure in the sliding chamber 111 pushes the piston 112 into place, and the oil pressure continues to rise to the set value, will the oil passage 141 open, and the hydraulic oil enters the second oil passage 102 to achieve automatic clamping; the longer the side pressure plate 130 extends, the higher the required pushing oil pressure, and the greater the corresponding clamping oil pressure, thereby achieving adaptive locking with a greater clamping force as the extension length increases.

[0050] Preferably, the adjusting block 144 is provided with a sealing ring 1441 on its outer periphery, the diameter of the adjusting block 144 is larger than the diameter of the oil passage 141, the adjusting block 144 is provided with a through oil drain hole 1442, and the base 100 is provided with a main drain port that cooperates with the oil drain hole 1442. When the electromagnet 143 is de-energized, the adjusting block 144 is reset under the action of the tension spring 145, and the oil drain hole 1442 is connected to the main drain port, so that the second oil passage 102 and the sealing cavity 121 are quickly depressurized.

[0051] It should be noted that when it is necessary to connect the first oil circuit 101 and the second oil circuit 102, the adjusting block 144 moves towards the electromagnet 143. At this time, the oil drain hole and the oil drain hole 1442 are not connected. Therefore, during continuous filling, the hydraulic oil inside the first oil circuit 101 will flow into the second oil circuit 102 through the oil passage 141, realizing the function of clamping the side pressure plate 130 after it has been extended and retracted to the designated position. After the side pressure plate 130 has finished working, when it is necessary to drain the hydraulic oil inside the second oil circuit 102 and the first oil circuit 101, the energization on the electromagnet 143 is released, and the tension spring is tightened. Under the rebound action of 145, the adjusting block 144 moves to the end away from the electromagnet 143 and returns to its original position. At this time, the drain hole 1442 is connected to the drain hole, so that all the hydraulic oil inside the second oil circuit 102 can be drained in, thereby releasing the clamping of the sealing cavity 121 and the clamping plate 123 on the side pressure plate 130. At the same time, as the hydraulic oil inside the first oil circuit 101 is slowly emptied by the hydraulic pump, the pressure difference between the first oil circuit 101 and the second oil circuit 102 gradually decreases until the hydraulic oil between the first oil circuit 101 and the second oil circuit 102 is completely emptied.

[0052] Preferably, a connector 1121 is fixed at the end of the piston 112 away from the piston head, and a connecting shaft 1122 is provided inside the connector 1121. The middle part of the side pressure plate 130 is hinged to the connecting shaft 1122, so that the side pressure plate 130 can swing around the connecting shaft 1122 to adjust the angle.

[0053] It should be noted that by detachably connecting the connecting shaft 1122 to the inside of the connector 1121, and by providing a rotating groove on the connector 1121 for the side pressure plate 130 to rotate around the connecting shaft 1122, the side pressure plate 130 can change its angle according to different engine components when the piston 112 drives the side pressure plate 130 to change its position.

[0054] Preferably, the side plates at both ends of the side pressure plate 130 are provided with waist holes 131, the clamping plate 123 is provided with a through mounting hole, a limit pin 132 is detachably provided in the mounting hole, and the clamping plug 122 is provided with a fixing hole 1221 corresponding to the mounting hole. The limit pin 132 passes through the waist hole 131 and is movably engaged with the fixing hole 1221. The waist hole 131 is used for guiding and limiting the side pressure plate 130 during the feeding and swinging process. In the clamping state, the clamping plug 122 and the clamping plate 123 lock the side pressure plate 130.

[0055] It should be noted that before the clamping plug 122 and the clamping plate 123 are clamped together, when the piston 112 drives the side pressure plate 130 to change position, when the engine parts are set at different angles, the limiting pin 132 can limit the position of the left and right side plates of the side pressure plate 130 when the side pressure plate 130 rotates around the connecting shaft 1122.

[0056] Preferably, a clamping return spring is provided between the clamping plug 122 and the sealing cavity 121. The clamping return spring is used to drive the clamping plug 122 to reset and release the side pressure plate 130 when the second oil circuit 102 is depressurized.

[0057] Preferably, the electromagnet 143 is a current-adjustable electromagnet 143. The preset oil pressure of the oil passage 141 opened by the adjusting block 144 can be adjusted according to the current of the electromagnet 143, so that the longer the side pressure plate 130 extends, the greater the clamping force of the clamping plug 122.

[0058] Preferably, the clamping plug 122 and the clamping plate 123 are provided with anti-slip toothed surfaces or flexible pressing pads on the side facing the side pressure plate 130, and the two ends of the side pressure plate 130 are provided with corresponding pressing mating surfaces.

[0059] Preferably, the base 100 is provided with a control interface for detecting the current of the electromagnet 143 and the oil pressure, and the control interface is electrically connected to an external hydraulic control system.

[0060] Working principle: When the device is working, the external hydraulic control system is connected through the control interface on the base 100 and injects hydraulic oil into the first oil circuit 101. After the hydraulic oil enters the sliding chamber 111, it pushes the piston 112 to overcome the elastic force of the telescopic spring 113 and feeds it outward, which drives the side pressure plate 130 connected to it to move synchronously. The side pressure plate 130 can be adjusted by swinging around the connector 1121 through the connecting shaft 1122 to adapt to different angles of aero-engine parts. During the feeding and angle adjustment process, the limit pin 132 cooperates with the waist hole 131 at both ends of the side pressure plate 130 to achieve guide limit and prevent the side pressure plate 130 from swinging or moving. Simultaneously, the adjustment mechanism 140 between the first oil circuit 101 and the second oil circuit 102 works synchronously. After the current adjustable electromagnet 143 is energized, the opening preset oil pressure of the adjustment block 144 can be set by the magnitude of the current. Only when the piston 112 drives the side pressure plate 130 to the position and the oil pressure in the sliding cavity 111 rises to the preset value, the oil pressure overcomes the force of the tension spring 145 and pushes the adjustment block 144 to move, opening the oil passage 141 connecting the two oil circuits. The hydraulic oil enters the second oil circuit 102 and flows into the sealing cavity 121, pushing the clamping plug 122 to move towards the clamping plate 123. Combined with the anti-slip structure on the clamping plug 122 and the clamping plate 123, the side pressure plate 130 is firmly clamped between the two. The longer the side pressure plate 130 extends, the higher the required feed oil pressure and the greater the corresponding clamping force, thus achieving adaptive locking. After processing, the electromagnet 143 is de-energized, and the adjusting block 144 is reset under the action of the tension spring 145. Its oil drain hole 1442 is connected to the main drain port, so that the second oil passage 102 and the sealing cavity 121 are quickly depressurized. The clamping plug 122 is reset and releases the side pressure plate 130 under the action of the clamping reset spring. Then the first oil passage 101 discharges hydraulic oil, and the extension spring 113 drives the piston 112 and the side pressure plate 130 to reset, completing a complete work cycle of clamping, processing and loosening.

[0061] In summary, the hydraulic side pressure plate for processing aero-engine components utilizes a hydraulic feed mechanism 110 and a clamping mechanism 120 respectively installed on the base 100. The hydraulic feed mechanism 110, through the cooperation of the sliding cavity 111, piston 112, telescopic spring 113, and first oil passage 101, injects hydraulic oil into the first oil passage 101 and controls the oil injection amount, achieving precise adjustment of the piston 112's position, thereby driving the side pressure plate 130 to the designated position. Simultaneously, hydraulic oil is injected into the sealing cavity 121 through the second oil passage 102, pushing the clamping plug 122 towards the clamping plate 123, thus moving the side pressure plate 130 to the designated position. The side pressure plate 130 is firmly fixed between the clamping plug 122 and the clamping plate 123. When unlocking, the hydraulic oil in the sealing chamber 121 is first discharged to reduce the clamping force, and then the hydraulic oil in the sliding chamber 111 is discharged. The side pressure plate 130 is reset by using the telescopic spring 113. This achieves precise control of the feed position of the side pressure plate 130 and a stable and reliable clamping state. It solves the problems of low positioning accuracy and weak clamping of traditional side pressure plates. It is suitable for the high-precision machining requirements of aero-engine parts, avoids dimensional deviations caused by part displacement during machining, and is easy to reset, improving machining efficiency, reducing operation difficulty, and ensuring the stability of machining quality.

[0062] The hydraulic side pressure plate used for processing aero-engine components connects the two ends of the first oil circuit 101 to the hydraulic oil chamber of the sliding cavity 111 and the first injection port, respectively, and the two ends of the second oil circuit 102 to the hydraulic oil chamber of the sealing cavity 121 and the second injection port, respectively. Oil nozzles are connected to the first injection port and the second injection port, and the oil nozzles are connected to a common electro-hydraulic oil pump. The hydraulic oil pump fills the first oil circuit 101 with liquid and controls the filling amount to achieve precise adjustment of the extension length of the piston 112, thereby changing the position of the side pressure plate 130. Then, the hydraulic oil pump fills the second oil circuit 102 with liquid and adjusts the liquid volume of the sealing cavity 121 to change the position of the clamping plug 122, thereby achieving a firm clamping of the side pressure plate 130. The achieved results are a simplified hydraulic oil injection and control process, enabling mechanization and precision of the side pressure plate 130 position adjustment and clamping action, eliminating the need for manual adjustment, reducing the intensity of manual operation, and allowing flexible adjustment of the side pressure plate 130 position according to different sizes and shapes of aero-engine parts, improving the versatility and adaptability of the device, shortening the part changeover and adjustment time, further improving processing efficiency, and ensuring stable hydraulic control to ensure uniform clamping force and avoid deformation of parts due to uneven force.

[0063] The hydraulic lateral clamping plate used for machining aero-engine components achieves automatic clamping after the lateral clamping plate 130 is fed into position, and adaptive matching of the extension length and clamping force, through a controllable connecting adjustment mechanism 140 consisting of an electromagnet 143, an adjusting block 144, a tension spring 145, and an oil passage 141, set between the first oil passage 101 and the second oil passage 102. When the electromagnet 143 is energized, the adjusting block 144 can be opened to open the oil pressure by setting the current magnitude. Only after the piston 112 is fed into position and the oil pressure in the sliding chamber 111 rises to the preset value will the adjusting block 144 be pushed to open the oil passage 141, allowing hydraulic oil to enter the second oil passage 102 to drive the clamping action. This design avoids interference and workpiece damage caused by clamping before the side pressure plate 130 is fully in place. The longer the side pressure plate 130 extends, the higher the required feed oil pressure, the greater the corresponding clamping opening pressure, and the higher the oil pressure entering the sealing cavity 121. Consequently, the clamping force of the clamping plug 122 on the side pressure plate 130 increases, thus automatically achieving adaptive locking with a greater clamping force as the extension length increases. This design can complete the sequential actions of feeding, holding pressure, and clamping without additional solenoid valves, sensors, or complex control programs, improving system response speed and operational stability, reducing control costs and potential failure points, and achieving the technical effects of reliable action logic, high clamping accuracy, strong safety, and outstanding adaptive capability.

[0064] This hydraulic lateral pressure plate for machining aero-engine components, by setting an oil drain hole 1442 on the adjusting block 144 and cooperating with the main drain port of the base 100, allows the adjusting block 144 to reset using a tension spring 145 when the electromagnet 143 is de-energized, thus achieving rapid pressure relief between the second oil passage 102 and the sealing cavity 121. Simultaneously, combined with the hinged connector 1121 of the piston 112 and the swing angle adjustment structure of the side pressure plate 130, and the guide and limiting structure of the limiting pin 132 and the waist hole 131, it achieves adaptive angle adjustment and rapid clamping and resetting during the clamping process of the side pressure plate 130. The side pressure plate 130 can swing around the connecting shaft 1122, adapting to the complex curved surfaces and different lateral pressures of aero-engine components. The tight angle enhances the tooling's ability to clamp irregularly shaped parts; the waist hole 131 and the limiting pin 132 provide guidance and limitation during feeding and angle adjustment, preventing the side pressure plate 130 from swaying or moving, and ensuring accurate clamping position; when depressurizing, the oil drain hole 1442 is directly connected to the main drain port, enabling the clamping mechanism 120 to quickly unload force, and in conjunction with the feed chamber extension spring 113 to reset, significantly shortening the clamping time and improving loading, unloading and changing efficiency; the overall structure has the advantages of adjustable angle, accurate guidance, reliable clamping, rapid depressurization, and smooth reset, effectively improving the processing and clamping efficiency and ease of use of aero-engine parts, achieving the effects of high clamping flexibility, simple operation, convenient maintenance and strong practicality.

[0065] This hydraulic lateral pressure plate for machining aero-engine components uses a connecting head 1121 fixed to one end of piston 112 away from the piston head. A connecting shaft 1122 is installed inside the connecting head 1121, and the middle of the side pressure plate 130 is hinged to the connecting shaft 1122, allowing the side pressure plate 130 to swing and adjust its angle around the connecting shaft 1122. Simultaneously, waist holes 131 are opened on the side plates at both ends of the side pressure plate 130. A clamping plate 123 has a through mounting hole and a limiting pin 132 is installed. The clamping plug 122 has a corresponding fixing hole 1221. The limiting pin 132 passes through the waist hole 131 and engages with the fixing hole 1221, guiding and limiting the feeding and swinging process of the side pressure plate 130. In the clamped state, the clamping... The plug 122 and clamping plate 123 lock the side pressure plate 130, enabling flexible adjustment of the angle of the side pressure plate 130 to meet the processing requirements of different angles of aero-engine parts. This solves the problem that the traditional side pressure plate 130 has a fixed angle and cannot be adapted to the processing of complex curved surfaces or irregular parts. At the same time, the cooperation between the limiting pin 132 and the waist hole 131 can effectively limit the swing amplitude and feed trajectory of the side pressure plate 130, prevent the side pressure plate 130 from shifting during the adjustment process, and ensure positioning accuracy. The locking structure in the clamping state further improves the clamping stability, prevents the side pressure plate 130 from loosening or shifting in angle during the processing, ensures the dimensional accuracy and surface quality of the parts, and broadens the application range of the device.
