Description

Technical Field

[0001] This utility model relates to the field of aircraft range extender test bench technology, specifically to a motor positioning fixture for an aircraft range extender test bench. Background Technology

[0002] With the continuous development of aviation technology, range extenders, as key components for improving aircraft range, have become particularly important for performance testing and verification. Range extender bench testing is an important means of evaluating range extender performance. It can comprehensively test various performance indicators of the range extender in an environment that simulates actual working conditions. In range extender bench testing, accurate positioning of the motor is one of the key factors to ensure the accuracy and reliability of test data. The selection of motor positioning fixtures for aviation range extender bench tests is crucial to the results of range extender bench tests.

[0003] However, existing motor positioning fixtures for aircraft range extender test benches have certain shortcomings in use. These fixtures can only position the motor in a fixed location and cannot adjust its horizontal position according to the requirements of the testing or maintenance equipment. This necessitates frequent movement of the entire test bench or equipment during multi-angle testing or maintenance, increasing operational complexity and time costs. Furthermore, existing fixtures lack a flipping function, or the flipping operation is not flexible or precise enough to meet the needs of testing at different angles. Finally, these fixtures can only provide simple fixation and cannot be precisely adjusted according to the different sizes and shapes of the motors. This may lead to motor displacement or vibration during testing or maintenance, affecting the accuracy of test results and the safety of maintenance work. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a motor positioning fixture for an aircraft range extender test bench.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a motor positioning fixture for an aircraft range extender test bench, including a support base, a flipping assembly, and a clamping assembly. Slide plates are movably fitted on both sides of the top of the support base. The flipping assembly is fixed to the top of the two slide plates. The clamping assembly of the positioning fixture is mounted on the flipping assembly, which is fixed to the top of the two slide plates. First slide rails are horizontally welded to both sides of the top of the support base. First sliders are welded to the bottom of both slide plates, and the first sliders slide in cooperation with the first slide rails. By sliding the slide plates on the first slide rails, the horizontal position of the motor can be adjusted. The flipping assembly is equipped with a flipper that can be flipped. The rotating plate has a clamping assembly fixed to the top of it. The positioning fixture is mounted on the rotating assembly. The clamping assembly includes a fixed base, two sliding plates, and two clamping plates. The fixed base is fixed to the rotating plate. The rotating plate is rotatably fitted on the top of two support frames. A drive motor for rotating the rotating plate is horizontally mounted on one side of the top of one of the support frames. By driving the rotating plate to rotate, the motor can be rotated, allowing the motor to be tested and repaired at multiple angles as needed. In addition, during the repair process, the replacement or repair of certain parts may require operation from a specific angle. The rotating assembly can provide the convenience of such angle adjustment.

[0006] The clamping assembly includes a fixed base, two sliding plates, and two clamping plates. The fixed base is fixed to the flip plate. The two sliding plates are respectively movably engaged at the top ends of the fixed base, and the two clamping plates are respectively movably engaged at the top of the two sliding plates. Two chucks are installed on the side of each of the two clamping plates that are close to each other. The clamping assembly of this positioning fixture uses the chucks on the two clamping plates to clamp and fix the motor. The two clamping plates are respectively set on the two sliding plates, and both clamping plates can be moved and adjusted on the two sliding plates. The distance between the two sliding plates can be adjusted. This design allows the clamping assembly to adapt to motors of different sizes and shapes. By adjusting the positions of the two clamping plates and the sliding plates, stable clamping of the motor can be achieved. The design of the chucks can provide sufficient clamping force.

[0007] Preferably, mounting seats are fixed at all four corners of the bottom of the support base. The support base has an overall "U"-shaped structure. First slide rails are horizontally welded to both sides of the top of the support base. First sliders are welded to the bottom of the two slide plates. The first sliders slide in cooperation with the first slide rails. The two slide plates move and cooperate on the top sides of the support base through the first sliders. Since the support base is fixed to the support surface by the mounting seats, only the mounting seats need to be operated during installation and disassembly. There is no need to make complex adjustments to other parts of the clamp. At the same time, the sliding cooperation between the slide plates and the support base also makes it easy to install or disassemble the slide plates and their components separately when needed, which is convenient for maintenance and repair of the clamp. The sliding cooperation between the first sliders and the first slide rails allows the slide plates to move horizontally on the support base, thereby driving the flipping component, clamping component and motor fixed on it to move together.

[0008] Preferably, the flipping assembly includes two support frames and a connecting plate. The two support frames are respectively fixed to the top of two slide plates, and the connecting plate is fixed between the two support frames. A first hydraulic cylinder is horizontally fixed at the top of the support frame away from the flipping assembly. A first hydraulic rod is provided at one end of the first hydraulic cylinder, and the end of the first hydraulic rod away from the first hydraulic cylinder is fixed to the connecting plate. The flipping plate is rotatably engaged with the top of the two support frames. A drive motor for driving the flipping plate to rotate is horizontally installed on one side of the top of one of the support frames. Driven by the first hydraulic cylinder, the first hydraulic rod moves, and the first hydraulic rod pulls the connecting plate. By pulling the connecting plate, the entire flipping assembly moves, and the drive motor drives the flipping plate to rotate. No manual operation is required, which greatly reduces the labor intensity of the operator. At the same time, the drive motor can also achieve precise positioning and control, ensuring that the flipping plate flips to the predetermined angle each time.

[0009] Preferably, the fixed base frame has an overall "U"-shaped structure. The top two sides of the fixed base frame are welded with second slide rails. The bottom of the two moving plates is welded with second sliders that slide in cooperation with the two second slide rails. A second hydraulic cylinder is horizontally fixed at the bottom of one of the moving plates. A second hydraulic rod is provided at one end of the second hydraulic cylinder. The end of the second hydraulic rod away from the second hydraulic cylinder is fixed to the bottom end of the other moving plate. The second hydraulic cylinder drives the second hydraulic rod to move, so that the second hydraulic cylinder and the second hydraulic rod can extend and retract, thereby driving the two moving plates to move synchronously in the same or opposite directions. The movement of the two moving plates drives the movement of the two clamping plates, thereby adjusting the distance between the two clamping plates.

[0010] Preferably, a third slide rail is welded to both sides of the top of the sliding plate, and a third slider that slides with the two third slide rails is welded to both sides of the bottom of the clamping plate. A mounting plate is vertically fixed to one end of the sliding plate, and a third hydraulic cylinder is horizontally fixed to the mounting plate. A third hydraulic rod is provided at one end of the third hydraulic cylinder, and the end of the third hydraulic rod away from the third hydraulic cylinder is fixed to the side of the clamping plate away from the chuck. The third hydraulic rod moves by the third hydraulic cylinder, and the third hydraulic rod pushes the clamping plate to move. By moving the two clamping plates, the clamping action is achieved. The two clamping plates are driven by different third hydraulic cylinders, and the movement of the two clamping plates during the clamping action is independent. This design allows the clamping assembly to adapt to motors of different sizes and shapes. By adjusting the position of the two clamping plates, stable clamping of the motor can be achieved. The two clamping plates can move independently to achieve the clamping action. At the same time, the two sliding plates can also drive the two clamping plates to move. Adjusting the distance between the two clamping plates allows both clamping plates to move in two stages. This design not only improves the flexibility of the clamping action, but also increases the adaptability and accuracy of the clamping.

[0011] Preferably, each of the two sliding plates has a bracket positioned between the two clamping plates at its top. Each bracket has two slots for holding the motor. An "L"-shaped fixing plate is welded to both sides of each bracket. The bottom of the fixing plate is rotatably fitted with a screw with a rotating plate. A pressing plate is fixed to the top of the screw, pressing against the bottom of the sliding plate. The bracket design provides additional support and protection for the motor. The slots secure the bottom of the motor, preventing it from sliding or tilting during positioning. The structure of the fixing plate and screw allows for fixing and adjustment of the bracket, and facilitates bracket replacement according to the motor model. Select a suitable bracket for installation and use to ensure its applicability and stability under different motor models and sizes. The bracket supports the motor, making the clamp more secure in fixing the motor. Based on the clamping of two plates, a bracket is set to support the motor, and the bracket supporting the motor has a matching slot. This design provides additional support and protection for the motor. The slot can fix the bottom of the motor and prevent it from sliding or tilting during positioning. Two slots are provided, and two clamps are set on each plate, so that the clamp can position two motors at the same time.

The flipping plate is rotated and fitted on the top of two support frames. A drive motor for driving the flipping plate to rotate is horizontally installed on one side of the top of one of the support frames. By driving the flipping plate to rotate through the drive motor, the motor can be flipped, so that the motor can be tested and repaired from multiple angles as needed. When testing the performance of the motor, it is necessary to observe its operating status and parameter changes from different angles. Through the flipping function of the flipping component, the motor can be easily adjusted to a suitable angle, which is convenient for testers to observe and record. In addition, during the repair process, the replacement or repair of some parts may need to be operated from a specific angle. The flipping component can provide the convenience of such angle adjustment, making the repair work more efficient and accurate. This multi-angle adjustment capability greatly improves the flexibility and convenience of motor testing and repair, and helps to improve work efficiency and quality.

The flipping component is fixed on the top of two slide plates. The top two sides of the support frame are horizontally welded with first slide rails. The bottom of the two slide plates is welded with first sliders. The first sliders slide in cooperation with the first slide rails. By sliding the slide plates on the first slide rails, the horizontal position of the motor can be adjusted. During motor testing or maintenance, the horizontal position of the motor needs to be adjusted according to the position of the testing equipment or maintenance tools in order to operate better. When testing the performance of the motor, the testing equipment may need to maintain a certain distance from the motor. By moving the slide plates, the motor can be adjusted to a suitable position to ensure normal connection and signal transmission between the testing equipment and the motor. In addition, during maintenance, maintenance personnel may need to adjust the position of the motor according to the range of use of the maintenance tools in order to operate more conveniently. By using the slide rail structure on the support frame, the horizontal position of the motor can be adjusted quickly and accurately, which improves the flexibility and convenience of motor testing and maintenance. It also provides convenience for the installation and disassembly of the motor.

In addition, during maintenance, maintenance personnel may need to adjust the position of the motor according to the range of use of the maintenance tools for easier operation. The slide rail structure on the support base 1 enables quick and accurate adjustment of the motor's horizontal position, improving the efficiency of motor operation. The flexibility and convenience of testing and maintenance, as well as the ease of installation and disassembly of the motor, are provided. The flipping assembly 2 includes a flipping plate 203 capable of flipping, and a clamping assembly 3 is fixed to the top of the flipping plate 203. This positioning fixture is mounted on the flipping assembly 2. The clamping assembly 3 includes a fixed base frame 6, two sliding plates 7, and two clamping plates 8. The fixed base frame 6 is fixed to the flipping plate 203, and the flipping plate 203 is rotatably fitted onto the tops of two support frames 201. A drive motor 204 for rotating the flipping plate 203 is horizontally mounted on one side of the top of one of the support frames 201. By driving the flipping plate 203 to rotate via the drive motor 204, the following can be achieved: The motor's flipping capability allows for multi-angle testing and maintenance as needed. When performing performance tests on a motor, it is necessary to observe its operating status and parameter changes from different angles.

The two clamping plates 8 are respectively set on the two sliding plates 7, and both clamping plates 8 can be moved and adjusted on the two sliding plates 7. The distance between the two sliding plates 7 can be adjusted. This design allows the clamping assembly 3 to adapt to motors of different sizes and shapes. By adjusting the positions of the two clamping plates 8 and the sliding plates 7... This system enables stable clamping of the motor. When testing or repairing different models of motors, whose sizes and shapes may vary, adjusting the clamping plate 8 and the shifting plate 7 ensures that the clamping assembly 3 can firmly hold the motor, preventing displacement or rotation during testing or repair.

First slide rails 102 are horizontally welded to both sides of the top of the support base 1. First sliders 401 are welded to the bottom of both slide plates 4. The first sliders 401 slide in engagement with the first slide rails 102. The two slide plates 4 move and engage on both sides of the top of the support base 1 via the first sliders 401. Since the support base 1 is fixed to the support surface by the mounting bases 101, only the mounting bases 101 need to be operated during installation and disassembly, without the need for complex adjustments to other parts of the clamp.

By pulling the connecting plate 202, the entire tilting assembly 2 moves, and the tilting plate 203 rotates via the drive motor 204. This eliminates the need for manual operation, greatly reducing the labor intensity of operators. At the same time, the drive motor 204 can also achieve precise positioning and control, ensuring that the tilting plate 203 tilts to the predetermined angle each time, improving the accuracy and repeatability of the operation. In addition, the motor drive system can also be connected to the control system to achieve automated operation, further improving work efficiency and quality.

[0028] In one optional embodiment of this invention, the fixed base 6 has an overall "U"-shaped structure. Second slide rails 601 are welded to both sides of the top of the fixed base 6. Second sliders 701 that slide in cooperation with the two second slide rails 601 are welded to the bottom of each of the two moving plates 7. A second hydraulic cylinder 702 is horizontally fixed to the bottom of one of the moving plates 7. A second hydraulic rod 703 is provided at one end of the second hydraulic cylinder 702.

The two moving plates 7 move synchronously in the same or opposite directions, driving the two clamping plates 8 to move, thereby adjusting the distance between the two clamping plates 8. This design allows the clamping assembly 3 to adapt to motors of different sizes and shapes. By adjusting the position of the two moving plates 7, stable clamping of the motor can be achieved. When testing or repairing different models of motors, the size and shape of the motors may be different. By adjusting the moving plates 7, it can be ensured that the clamping plates 8 can tightly clamp the motor, preventing it from shifting or rotating during testing or repair.

This is useful for testing different models of motors or... During maintenance, the size and shape of the motor may vary. By adjusting the clamping plate 8, it can be ensured that the clamping plate 8 can firmly clamp the motor, preventing displacement or rotation during testing or maintenance. In addition, the hydraulically driven clamping action can achieve automated operation, reducing the labor intensity of operators and improving work efficiency. The two clamping plates 8 can move independently to achieve clamping action. At the same time, the two moving plates 7 can also drive the two clamping plates 8 to move. Adjusting the distance between the two clamping plates 8 allows both clamping plates 8 to move in two stages. This design not only improves the flexibility of clamping action but also increases the adaptability and precision of clamping. When clamping the motor, the clamping plate 8 can first be adjusted to the approximate position by moving the moving plate 7. Then, through the precise control of the third hydraulic cylinder 706 and the third hydraulic rod 707, the clamping plate 8 can be finely adjusted to ensure uniform and stable clamping force.
