Description

Technical Field

[0001] This application relates to the field of aircraft component manufacturing and installation equipment, and more specifically, to a one-way valve assembly device. Background Technology

[0002] One-way valves are key components in the modern aerospace manufacturing industry, such as... Figure 1 and 2 As shown, the one-way valve mainly includes an adjusting screw and a valve body housing. The assembly of the one-way valve requires extremely high precision in the screwing depth of the adjusting screw into the valve body housing, that is, the distance L between the top surface of the adjusting screw and the top surface of the valve body housing after the adjusting screw is screwed into the valve body housing. Typically, L needs to be precisely controlled within the range of 1±0.1mm. This precision requirement is the basis for ensuring the stable and reliable operation of the one-way valve and even the entire aviation system.

[0003] Currently, the assembly of one-way valves is still done manually. During the assembly process, the operator first uses a vise to fix the valve body shell, and then, holding a flathead screwdriver, manually and slowly screws the adjusting plug into the valve body shell based on experience. Due to the high precision required for screwing, the operator has to frequently use calipers to measure the distance between the top face of the adjusting plug and the top face of the valve body shell to adjust the screwing depth. The traditional manual assembly method is inefficient. Due to individual differences in the operator's skill level and practical experience, it is difficult to accurately control the depth of the adjusting plug screwed into the valve body shell, making it difficult to guarantee the final pass rate of the one-way valve products.

[0004] There is an urgent need to improve the existing assembly method of one-way valves in order to increase the assembly efficiency and product qualification rate of one-way valves. Summary of the Invention

[0005] To at least partially solve the aforementioned technical problems, this application proposes a one-way valve assembly device. The device includes:

[0006] The feeding assembly includes a tightening head module that moves up and down axially along the adjusting screw of the one-way valve to screw the adjusting screw into the valve body housing of the one-way valve.

[0007] A fixing component, the fixing component being used to fix the valve body housing; and

[0008] The measurement and control unit calculates the screwing depth of the adjusting screw into the valve body shell in real time, and controls the movement of the tightening head module according to the screwing depth.

[0009] Preferably, the feed assembly further includes a fixed base and a servo module, and the tightening head module is mounted on the servo module.

[0010] Preferably, the tightening head module includes a tightening shaft, and a spring plunger is provided at the end of the tightening shaft. The spring plunger is engaged in the slot of the adjusting screw to drive the adjusting screw to rotate.

[0011] Preferably, the tightening head module further includes a reverse movement part, which includes a telescopic spring, a guide shaft, and a linear bearing, for enabling the tightening shaft to move relative to the tightening head module in the direction of tightening the adjusting screw, so as to avoid damaging the one-way valve.

[0012] Preferably, the tightening head module includes a displacement sensor, which is used to measure in real time the moving distance of the tightening head module in the tightening direction of the adjusting screw and the moving distance of the tightening shaft relative to the tightening head module in the tightening direction of the adjusting screw.

[0013] Preferably, the tightening head module further includes a second fixed base, a tightening motor, a first coupling, and a second coupling, wherein the tightening motor is used to drive the tightening shaft to rotate.

[0014] Preferably, the fixing assembly includes a centering V-shaped clamping block, a clamping cylinder, and a placement platform. The clamping cylinder is fixed on the placement platform, and the valve body shell is placed on the placement platform. The fixing assembly clamps the valve body shell in a centered manner through the centering V-shaped clamping block and the clamping cylinder.

[0015] Preferably, the formula for the screw-in depth L is as follows:

[0016] L = H - L0 + (L2 - L1),

[0017] Wherein, L0 represents the distance between the mounting surface of the spring plunger at the end of the tightening shaft and the placement platform in the initial state, H represents the height of the valve body shell, L2 represents the moving distance of the tightening head module in the tightening direction of the adjusting screw, and L1 represents the moving distance of the tightening shaft relative to the tightening head module in the tightening direction of the adjusting screw.

[0018] According to the one-way valve assembly device of this application, the device includes a feeding component, a fixing component, and a measurement and control unit. During the assembly process, the device calculates the screwing depth of the adjusting screw plug into the valve body housing in real time through the measurement and control unit, and controls the movement of the tightening head module of the feeding component based on the screwing depth. The tightening head module screws the adjusting screw plug into the valve body housing fixed by the fixing component. This device can precisely control the screwing depth of the adjusting screw plug into the valve body housing. Compared with the existing one-way valve assembly that relies on manual operation, the technical solution of this application effectively overcomes the uncontrollable assembly accuracy caused by individual differences in experience and skills during manual operation, ensuring the consistency and stability of assembly, and improving the assembly efficiency and product qualification rate of one-way valves.

[0033] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Figure 3 A schematic top view of the one-way valve assembly device according to this application is shown. Figure 3 As shown, the one-way valve assembly device includes a feeding assembly, a fixing assembly, and a measurement and control unit.

[0035] The feed assembly includes a tightening head module that moves axially along the adjusting screw of the one-way valve to screw the adjusting screw into the valve body housing of the one-way valve.

[0036] In some embodiments of this application, such as Figure 3 As shown, the feed assembly also includes a mounting base and a servo module, with the tightening head module mounted on the servo module.

[0037] In some embodiments of this application, such as Figure 5 and 7 As shown, Figure 7 yes Figure 6 The enlarged view of the circled part shows that the tightening head module includes a tightening shaft, with a spring plunger at the end of the tightening shaft. The spring plunger is engaged in the slot of the adjusting screw to drive the adjusting screw to rotate.

[0038] In some embodiments, two or more spring plungers 1030901 are provided at the end of the tightening shaft 10309.

[0039] In some embodiments of this application, such as Figure 4 As shown, the tightening head module also includes a reverse movement section, which includes a telescopic spring, a guide shaft, and a linear bearing. This reverse movement section allows the tightening shaft to move relative to the tightening head module in the direction of tightening the adjusting screw, thus preventing damage to the one-way valve. In some embodiments, when the tightening shaft presses against the adjusting screw, the telescopic spring is compressed, providing a reverse buffer displacement for the tightening shaft. The elastic deformation of the spring absorbs the instantaneous impact force, effectively preventing direct squeezing or hard impact on the one-way valve when the tightening shaft suddenly contacts and presses against the adjusting screw, thereby improving the integrity and operational reliability of the one-way valve.

[0040] In some embodiments of this application, such as Figure 4 As shown, the tightening head module includes a displacement sensor, which is used to measure in real time the moving distance of the tightening head module in the tightening direction of the adjusting screw and the moving distance of the tightening shaft relative to the tightening head module in the tightening direction of the adjusting screw.

[0041] In some embodiments, the displacement sensor 10301 is a high-precision laser displacement sensor.

[0042] In some embodiments, the displacement sensor 10301 has a measurement resolution down to the micrometer level.

[0043] In some embodiments of this application, such as Figure 4 As shown, the tightening head module also includes a fixed base two, a tightening motor, a coupling one, and a coupling two. The reverse moving part is fixed on the fixed base two of the tightening head module. The tightening motor is fixedly connected to the reverse moving part and is used to drive the tightening shaft to rotate. Coupling one is fixedly connected to the motor shaft of the tightening motor, and coupling two is fixedly connected to the tightening shaft. The function of the coupling is to efficiently transmit the torque output by the tightening motor to the tightening shaft and to ensure the stability of power transmission. Coupling one and coupling two have flexible adjustment capability when transmitting torque, which can effectively compensate for possible coaxiality deviations between the tightening shaft and the motor shaft, avoid equipment vibration problems caused by installation errors or slight displacement during operation, and ensure the smooth operation of the transmission system.

[0044] In some embodiments, the tightening head module further includes a connector.

[0045] The fixing component is used to fix the valve body housing.

[0046] In some embodiments of this application, such as Figure 3 As shown, the fixing assembly includes a centering V-shaped clamping block, a clamping cylinder, and a placement platform. The clamping cylinder is fixed on the placement platform, and the valve body shell is placed on the placement platform. The fixing assembly clamps the valve body shell by centering the V-shaped clamping block and the clamping cylinder.

[0047] The measurement and control unit calculates the screwing depth of the adjusting plug into the valve body shell in real time, and controls the movement of the tightening head module according to the screwing depth.

[0048] In some embodiments of this application, the formula for the screw-in depth L is as follows:

[0049] L = H - L0 + (L2 - L1),

[0050] Where L0 represents the distance between the mounting surface of the spring plunger at the end of the tightening shaft and the placement platform in the initial state, H represents the height of the valve body shell itself, L2 represents the distance the tightening head module moves in the direction of screwing into the adjusting screw, and L1 represents the distance the tightening shaft moves relative to the tightening head module in the direction of screwing out of the adjusting screw.

[0051] In some embodiments, the assembly accuracy of the one-way valve assembly device of this application can reach ±0.02mm, which is a huge improvement in accuracy compared to the existing manual operation which can only control the accuracy standard to ±0.1mm.

[0052] like Figures 3 to 7As shown, the one-way valve assembly device of this application not only has excellent functionality, but also features a lightweight structure and convenient operation. Operators can master it without undergoing long and complex training. Furthermore, by selecting reasonable materials and processes, the manufacturing cost of the device can be effectively reduced, which is conducive to large-scale promotion and application and creates higher economic benefits for enterprises.

[0053] The following will combine Figure 8 The assembly process of a certain one-way valve is used as an example for further explanation. Among them, Figure 8 The black outline in the figure represents the initial state of the one-way valve assembly before the adjusting screw is screwed into the valve body housing. Figure 8 The red outline in the image indicates the state of the one-way valve assembly after the adjusting plug is screwed into the valve body housing.

[0054] In this example, the assembly process steps for the one-way valve include:

[0055] The first step is for the operator to install the adjusting screw and valve body housing of the one-way valve into the one-way valve assembly device of this application, and click the "clamp" button to fix the valve body housing.

[0056] The second step is for the operator to select the one-way valve model on the screen of the one-way valve assembly device in this application and click the "Automatic Adjustment" button;

[0057] Third, after the one-way valve is assembled, click the "Release" button and remove the assembled one-way valve.

[0058] The specific explanation for the second step above is as follows:

[0059] Before clicking the "Auto Adjust" button, the distance between the mounting surface of the spring plunger at the end of the tightening shaft and the placement platform needs to be set in the measurement and control unit of the one-way valve assembly device of this application. The distance between the top surface of the valve body shell of this model and the placement platform is the height of the valve body shell itself.

[0060] After clicking the "Auto Adjust" button, the tightening head module moves downward until the tightening shaft of the tightening head module abuts the adjusting screw of the one-way valve. At the same time, the displacement sensor measures in real time the distance the tightening head module moves in the direction of tightening into the adjusting screw, as well as the distance the tightening shaft moves relative to the tightening head module in the direction of tightening out of the adjusting screw.

[0061] After the tightening shaft presses against the adjusting screw plug, the tightening motor drives the tightening shaft to rotate. The spring plunger at the end of the tightening shaft engages in the slot of the adjusting screw plug. The tightening head module continues to move downwards, causing the adjusting screw plug to be screwed into the valve body housing. During this screwing process, the measurement and control unit calculates the distance L between the top surface of the adjusting screw plug and the top surface of the valve body housing in real time. The calculation formula is as follows.

[0062] L = H - L0 + (L2 - L1),

[0063] Where L0 represents the distance between the mounting surface of the spring plunger at the end of the tightening shaft and the placement platform, H represents the height of the valve body housing, L2 represents the moving distance of the tightening head module, and L1 represents the moving distance in the tightening direction of the axial adjusting screw plug.

[0064] The tightening head module stops moving when the distance L between the top surface of the adjusting screw and the top surface of the valve body reaches the set value.

[0065] Figure 8 In this context, L actually refers to the actual descent distance of the tightening shaft.
