Description

Technical Field

[0001] This invention relates to the field of product testing technology, and in particular to an attitude adjustment device for a four-channel control device. Background Technology

[0002] See Figure 1 The control device 8 for the aircraft's servo motors has a diameter of approximately 200mm and a length of approximately 150mm. It includes four transmission mechanism output channels 81, distributed at 90-degree angles around the circumference. During the product testing of the control device 8, see [link to relevant documentation]. Figure 2 First, the product needs to be installed inside the chamber 7 of the test platform 100. Then, the test instrument 15 is installed on the output channel 81 of the transmission mechanism under test, and the test equipment is connected. Next, the performance of the product's output channel 81 is tested according to the corresponding test requirements and procedures. Since the control device 8 is a four-channel control device, containing four transmission mechanism output channels 81, each of the four output channels 81 needs to be tested separately during product testing. Because severe vibrations may occur during testing, to ensure consistency of test conditions and avoid equipment damage, the control device 8 needs to be fixedly installed inside the chamber 7 of the test platform 100 during testing, and the chamber 7 also needs to be fixedly installed on the test platform 100.

[0003] Existing testing methods generally fall into two categories. The first method involves removing all 24 fastening screws of the control device 8 after testing a specific channel, detaching the control device 8 from the housing, adjusting its installation angle, and then reinstalling it to ensure the output channel 81 under test is horizontal. The testing instrument 15 and other equipment are then connected to this channel for performance testing. Using this existing method, the performance testing of the four channels of the control device requires repeated disassembly and reassembly, with most of the process being repetitive. The disassembly and reassembly process takes approximately 70 minutes, which is time-consuming and inefficient.

[0004] The second testing method involves disconnecting the testing equipment from the control device after completing the test of one of its channels. Then, the position and orientation of the testing instruments and equipment are adjusted to align with the next channel to be tested and installed. Because the four channels of the control device are distributed in a 90° circle, the position of the instruments and equipment needs to be adjusted and fixed for each test, which is time-consuming and labor-intensive. The test position and status of the equipment cannot be consistent, resulting in poor consistency of test data and low testing efficiency. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide an attitude adjustment device and method for a four-channel control device, in order to solve the problem that the control device needs to be repeatedly disassembled and reassembled to switch attitudes during the testing process in the prior art.

[0006] On one hand, this paper proposes an attitude adjustment device for a four-channel control device, including a fixed platform, a bracket, a drive assembly, a locking component, a rotating base, and a cabin. The bracket is fixedly mounted on the fixed platform, the drive assembly is mounted on the top of the bracket, the output end of the drive assembly is fixedly connected to the rotating base, and the drive assembly can drive the rotating base to rotate. The locking component is mounted on the upper part of the bracket and located on the side of the rotating base, and the locking component can abut against the side of the rotating base to restrict the rotation of the rotating base. The cabin is fixedly mounted on the rotating base and coaxial with the rotating base, and the cabin is used to install the four-channel control device.

[0007] Furthermore, the drive assembly includes a motor mounting bracket, a motor, a support base, and a rotating shaft; the motor mounting bracket and the support base are both fixedly mounted on the bracket, the motor is fixedly mounted on the motor mounting bracket, the rotating shaft is rotatably mounted inside the support base, the output shaft of the motor is connected to the first end of the rotating shaft, and the second end of the rotating shaft is connected to the cabin rotating base.

[0008] Furthermore, the locking component includes a pressure block, and four clamping planes are evenly distributed circumferentially on the outer surface of the cabin rotating base. The pressure block can press against any one of the clamping planes to fix the cabin rotating base at the required angle position and restrict the rotation of the cabin rotating base.

[0009] Furthermore, the locking component also includes a locking seat and an intermediate adjusting screw. The intermediate adjusting screw is disposed in a screw hole in the locking seat, and the pressure block is fixedly disposed at the end of the intermediate adjusting screw and can be driven to reciprocate by the intermediate adjusting screw.

[0010] Furthermore, the rotating base of the cabin includes a base plate and a mounting sleeve that are fixedly connected together.

[0011] Furthermore, the base plate is used for fixed connection with the drive assembly, and the mounting sleeve is used for fixed connection with the cabin body.

[0012] Furthermore, the substrate is a circular plate, and four clamping planes are evenly distributed circumferentially on the outer peripheral surface of the substrate.

[0013] Furthermore, test holes corresponding to the four output channels of the four-channel control device are provided on the cylindrical surface of the cabin.

[0014] Furthermore, when any one of the four clamping planes is abutted by the locking component, one of the test holes is in the test position.

[0015] Furthermore, the inner surface of the mounting sleeve is provided with an annular mounting platform, which extends radially inward along the inner surface of the mounting sleeve. The end face of the annular mounting platform is provided with a plurality of axially extending threaded holes for fixing the mounting sleeve to the substrate together by bolts.

[0016] Furthermore, the locking component also includes a limiting rod and a first spring. The limiting rod is slidably disposed in the through hole of the locking seat. The axis of the limiting rod is parallel to the axis of the intermediate adjusting screw. A limiting nut is provided at the end of the limiting rod away from the pressure block. The other end of the limiting rod is fixedly connected to the pressure block. The first spring is sleeved on the limiting rod, and one end of the first spring abuts against the locking seat, while the other end abuts against the pressure block.

[0017] Furthermore, it also includes an automatic correction device, which is fixedly mounted on the bracket and used to automatically correct the rotation angle of the cabin rotating base.

[0018] Furthermore, the automatic calibration device includes a mounting block, a calibration cylinder, and a first guide post; the calibration cylinder is fixedly mounted on the bracket via the mounting block, and the first guide post is fixedly mounted on the output end of the calibration cylinder.

[0019] Furthermore, four calibration holes are evenly distributed on the outer circumferential surface of the cabin rotating base. When the cabin rotating base is rotated into position, the first guide post can be inserted into the corresponding calibration hole along the axial direction.

[0020] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0021] (1) The attitude of the control device can be directly adjusted.

[0022] The rotation of the shaft drives the cabin to rotate, thereby enabling rapid adjustment of the control device's attitude. This eliminates the need for repetitive disassembly and assembly of the control device, reducing the time spent on repetitive disassembly and assembly during three channel switching operations and improving the efficiency of control device performance testing.

[0023] (2) The testing process is highly stable.

[0024] The use of locking components enables rapid and reliable locking of the cabin, preventing the control device from moving due to vibration during testing and ensuring the consistency of test conditions for the test equipment.

[0025] (3) Adjustments can be completed automatically.

[0026] The cabin's attitude is automatically adjusted by motors, greatly reducing the intensity of manual operation.

[0027] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages may become apparent from the description or be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained from what is particularly pointed out in the description and drawings. Attached Figure Description

Detailed Implementation

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0047] Example 1

[0048] This invention proposes an attitude adjustment device for a four-channel control system, see [link to relevant documentation]. Figures 3-4 The adjustment device includes: a fixed platform 1, a bracket 2, a drive assembly, a locking component 3, a cabin rotation base 4, and a cabin 7. This adjustment device is used to adjust the attitude of the control device 8, facilitating testing using the testing instrument 15.

[0049] The drive components include a rotating shaft 5, a support base 6, a servo motor 9, and a motor mounting bracket 10.

[0050] See Figure 5 The fixed platform 1 includes a flat plate and four support legs. The flat plate has multiple mounting holes. The fixed platform 1 is used for the installation and placement of the bracket 2, the cabin rotation base 4, the cabin 7, the testing instruments 15, etc.

[0051] See Figure 6 The bracket 2 includes a horizontally arranged base plate and a vertically arranged support plate. The support plate is fixedly connected to the middle of the upper surface of the base plate, and four support ribs are respectively provided at both ends of the support plate. The base plate is provided with multiple threaded through holes, which are adapted to the mounting holes provided on the fixed platform 1, and the bracket 2 can be fixedly installed on the fixed platform 1 by bolts.

[0052] See Figure 3 and Figure 6 A motor mounting bracket 10 and a support base 6 are fixedly installed on the top of the support plate. The motor mounting bracket 10 has an L-shaped structure, with the free end of its horizontal plate fixed to the first side wall of the support plate. The servo motor 9 is installed on the vertical plate of the motor mounting bracket 10 on the side away from the support plate. The output shaft of the servo motor 9 passes through the vertical plate of the motor mounting bracket 10 and extends toward the support plate.

[0053] See Figure 9 The support base 6 includes a square main body and mounting lugs on both sides. A through hole is located in the center of the square main body, and the rotating shaft 5 is disposed within this through hole. See also... Figure 3 The support base 6 is bolted to the first side wall of the top of the support plate by mounting lugs on both sides, located above the horizontal plate of the motor mounting bracket 10.

[0054] See Figure 8 The rotating shaft 5 is a stepped shaft, with the diameter of its first end smaller than the diameter of its second end. Multiple circumferentially distributed threaded holes are provided on the end face of the second end. (See also...) Figure 3 The rotating shaft 5 is supported in the through hole of the support base 6 by two bearings. The first end of the rotating shaft 5 is connected to the output shaft of the servo motor 9, and the second end extends out of the support base 6 and is fixedly connected to the rotating base 4 of the cabin.

[0055] See Figures 6-7 The cabin rotating base 4 includes a base plate 41, which is approximately circular. Four clamping planes 44 are evenly distributed along the circumferential direction on its side. Multiple threaded holes are provided in the center of the base plate 41. These threaded holes correspond to the threaded holes on the end face of the second end of the rotating shaft 5, and are used to fix the rotating shaft 5 to the cabin rotating base 4 together with bolts.

[0056] The hull rotating base 4 also includes a mounting sleeve 42. An annular mounting platform 45 is provided on the inner surface of the mounting sleeve 42. The annular mounting platform 45 extends radially inward along the inner surface of the mounting sleeve 42. Multiple axially extending threaded holes are provided on the end face of the annular mounting platform 45, allowing the mounting sleeve 42 to be fixedly connected to the base plate 41 using bolts. A circular opening 43 is provided at the center of the annular mounting platform 45 to facilitate the installation and removal of the rotating shaft 5.

[0057] The mounting sleeve 42 has multiple cabin mounting holes 46 evenly distributed on its circumferential surface, suitable for mounting the cabin 7. The control device 8 is fixedly installed inside the cabin 7, and test holes corresponding one-to-one with the four output channels of the control device 8 are provided on the cabin 7. When any one of the four clamping planes 44 is abutted by the pressure block 31 of the locking component 3, one of the test holes is in the test position.

[0058] See Figure 4 and Figure 6 The locking component 3 includes a locking seat 30, a pressure block 31, an intermediate adjusting screw 32, a limit rod 33, and a first spring 34.

[0059] The locking seat 30 includes a locking mounting plate and a locking support plate fixedly connected. The locking mounting plate is fixedly mounted on the bracket 2 and located on one side of the hull rotating base 4. The locking support plate has a threaded hole in the center and through holes on both sides of the threaded hole. The intermediate adjusting screw 32 is disposed in the threaded hole and its end is fixedly connected to the pressure block 31. The pressure block 31 is used to abut against the clamping plane 44 of the hull rotating base 4. Turning the intermediate adjusting screw 32 can drive the pressure block 31 to move closer to or further away from the hull rotating base 4. The clamping force applied by the pressure block 31 to the hull rotating base 4 can be adjusted by adjusting the position of the intermediate adjusting screw 32.

[0060] A limiting rod 33 is provided in each through hole of the locking support plate. The axis of the limiting rod 33 is parallel to the axis of the intermediate adjusting screw 32. A limiting nut is provided at the end of the limiting rod 33 away from the pressure block 31, and the other end of the limiting rod 33 is fixedly connected to the pressure block 31. A first spring 34 is sleeved on the limiting rod 33, with one end of the first spring 34 abutting against one side surface of the locking support plate of the locking seat 30, and the other end abutting against the pressure block 31. By setting the limiting rod 33 and the first spring 34, the movement of the pressure block 31 can be guided, preventing the pressure block 31 from tilting or rotating, and the clamping force applied to the pressure block 31 can also be increased.

[0061] The locking component 3 presses the clamping plane 44 of the cabin rotating base 4 tightly against the front end of the pressure block 31, thereby locking the cabin rotating base 4. Loosening the middle adjusting screw 32 of the locking component 3 allows the pressure block 31 at the front end of the locking component 3 to be in a free state, thereby unlocking the cabin rotating base 4 and the cabin 7. The limiting rods 33 and the matching first springs 34 installed on both sides of the locking component 3 can control the position of the pressure block 31 and prevent the pressure block 31 from rotating during the locking and unlocking process, thus affecting the locking effect. At the same time, when the cabin rotating base 4 drives the cabin 7 to rotate, it does not affect the normal rotation of the cabin rotating base 4.

[0062] By setting the locking component 3, the impact of vibration during the test can be effectively reduced, thereby improving the accuracy of the test.

[0063] Preferably, two locking components 3 are symmetrically arranged on both sides of the rotating base 4 of the cabin, so that the force on the rotating base 4 of the cabin is more balanced and more stable during the test.

[0064] The testing instrument 15 is fixedly mounted on the fixed platform 1, and the output channel 81 of the control device 8 is connected to and fixed to the testing instrument 15 in sequence during the test.

[0065] The attitude adjustment device for a four-channel control device of the present invention enables rapid adjustment and locking of the attitude of the control device 8 by adjusting and locking the attitude of the cabin.

[0066] The working principle of this device is as follows: When the control device 8 needs to be tested, the cabin 7 is installed on the cabin rotating base 4, and the control device 8 is installed inside the cabin 7. The rotation angle of the cabin rotating base 4 is controlled by the servo motor 9, thereby realizing the rapid adjustment of the cabin 7's attitude. After the cabin rotating base 4 drives the control device 8 installed inside the cabin 7 to adjust the output channel 81 to be tested to the test position, the middle adjusting screws 32 of the locking components 3 on both sides of the cabin rotating base 4 are alternately tightened, so that the pressure blocks 31 at both ends press the cabin rotating base 4, realizing the rapid and reliable locking of the cabin 7, making the product ready for performance testing. Then, the testing instrument 15 is connected for testing.

[0067] When the control device 8 completes the test of one output channel 81 and needs to switch to another output channel 81, first disconnect the test instrument 15 from the control device 8, then loosen the middle adjusting screw 32 of the locking component 3, so that the pressure block 31 is in a free state, and the chamber rotating base 4 is in an unlocked state and can rotate. The servo motor 9 controls the rotating shaft 5, driving the chamber 7 and the control device 8 to rotate, adjusting the next output channel 81 to be tested of the control device 8 to the test position, thereby realizing the rapid adjustment of the position of the channel to be tested of the control device 8.

[0068] The present invention provides a rapid attitude adjustment device for a four-channel control device, which realizes rapid and automatic adjustment and locking of the attitude of the control device, greatly reduces disassembly and assembly time, ensures the consistency of test conditions of test equipment, and improves the performance testing efficiency of the control device.

[0069] Example 2

[0070] This embodiment 2 relates to an attitude adjustment device for a four-channel control device, see [link]. Figures 10-15 In addition to the parts that are the same as in Embodiment 1, it also includes a square support 11, an automatic tightening device 12, an automatic correction device 13, and an automatic lifting device 14.

[0071] See Figure 10 There are two square supports 11, which are fixedly installed on the fixed platform 1 and located on both sides of the bracket 2. Each square support 11 is equipped with an automatic tightening device 12.

[0072] Two automatic tightening devices 12 are located on both sides of the cabin rotating base 4. The automatic tightening devices 12 can automatically tighten or unload the middle adjusting screw 32 of the locking component 3. Through program setting, the locking component 3 can automatically switch between the locked and unlocked states, thereby realizing the locking or unlocking of the cabin rotating base 4.

[0073] See Figures 12-13 The automatic tightening device 12 includes a forward cylinder 123, a sliding platform 126, an automatic screwdriver 121, and a primary guide rail 124. The forward cylinder 123 and the primary guide rail 124 are both fixedly mounted on the top of the square support 11. The sliding platform 126 is mounted on the primary guide rail 124, and the output end of the forward cylinder 123 is fixedly connected to the bottom of the sliding platform 126, enabling it to drive the sliding platform 126 to reciprocate.

[0074] An automatic screwdriver 121 is mounted on the sliding platform 126. The output end of the automatic screwdriver 121 can engage with the intermediate adjusting screw 32 of the locking component 3, and can drive the intermediate adjusting screw 32 to rotate.

[0075] The forward cylinder 123 controls the forward and backward movement of the automatic screw gun 121, and the electric screw gun 121 tightens or loosens the adjusting screw 32 of the locking component 3. The electric screw gun 121 controls the extension length of the adjusting screw 32 according to the torque and number of turns, thereby controlling the clamping force on the cabin rotating base 4, so that the clamping force on both sides of the cabin rotating base 4 is consistent.

[0076] When the intermediate adjusting screw 32 of the locking component 3 is tightened by the automatic tightening device 12, the pressure block 31 at the front end of the locking component 3 presses against the cabin rotating base 4, thereby locking the cabin rotating base 4 and the cabin 7; when the intermediate adjusting screw 32 of the locking component 3 is loosened and unloaded by the automatic tightening device 12, the pressure block 31 at the front end of the locking component 3 is in a free state, thereby unlocking the cabin rotating base 4 and the cabin 7.

[0077] In some preferred embodiments, see Figures 12-13 The automatic tightening device 12 also includes a clamping cylinder 122, a secondary guide rail, a slider, a push rod 127, a screw 128, and a second spring 125.

[0078] The secondary guide rails include a left guide rail 1211 and a right guide rail 1212 arranged parallel to each other. A left slider 1210 is mounted on the left guide rail 1211, and a right slider 129 is mounted on the right guide rail 1212. A clamping cylinder 122 is fixedly mounted on the sliding platform 126, and its output end is fixedly connected to a push rod 127. One end of the push rod 127 is fixedly connected to the left slider 1210, and the other end has a through hole through which a screw 128 passes and is fixedly connected to the right slider 129. A nut is provided at the free end of the screw 128, and a second spring 125 is sleeved on the screw 128, with one end of the second spring 125 abutting against the nut and the other end abutting against the push rod 127. An electric screwdriver 121 is fixedly mounted on the right slider 129.

[0079] During operation, the output end of the clamping cylinder 122 extends forward, driving the left slider 1210 forward via the push rod 127. The other end of the push rod 127 compresses the second spring 125, which in turn drives the right slider 129 forward via the nut and screw 128. This ensures that there is always a preload between the electric screw gun 121 and the intermediate adjusting screw 32, and that they are in reliable contact.

[0080] It also ensures that the intermediate adjusting screw 32 can be loosened normally. When the intermediate adjusting screw 32 needs to be turned in the opposite direction, the intermediate adjusting screw 32 will be displaced in the direction of the electric screw gun 121, which will drive the electric screw gun 121 to move backward, thereby causing the right slider 129 to move backward and further compress the second spring 125. This ensures that there is always a preload and reliable contact between the electric screw gun 121 and the intermediate adjusting screw 32 during the reverse drive process.

[0081] See Figure 10 , Figure 11 as well as Figure 14The automatic calibration device 13 is fixedly mounted on the bracket 2. The automatic calibration device 13 includes a mounting block, a calibration cylinder 131, and a first guide post 132. The calibration cylinder 131 is vertically mounted on the bracket 2 via the mounting block, located below the cabin rotating base 4. The first guide post 132 is located at the output end of the calibration cylinder 131 and can be driven up and down by the calibration cylinder 131.

[0082] Correspondingly, four calibration holes are evenly distributed on the outer circumferential surface of the cabin rotation base 4, and the first guide post 132 can be inserted into any one of the calibration holes along the axial direction. When the first guide post 132 is inserted into the calibration hole, the rotation angle of the cabin rotation base 4 can be further adjusted so that the output channel 81 of the control device 8 inside the cabin 7 is exactly connected with the test instrument 15.

[0083] By setting up the automatic calibration device 13, the rotation angle of the cabin rotating base 4 can be precisely controlled, thereby ensuring that the output channel 81 of the control device 8 and the test instrument 15 can be accurately connected.

[0084] In some preferred embodiments, an outer conical surface is provided at the end of the first guide post 132, and correspondingly, a matching inner conical surface is provided in the calibration hole of the cabin rotating base 4. When the first guide post 132 is inserted into the calibration hole, the outer conical surface and the inner conical surface fit tightly together, which can further ensure positioning accuracy.

[0085] See Figure 10 , Figure 11 , Figure 15 In this embodiment 2, the automatic lifting device 14 is mounted on the fixed platform 1 and is used to install and drive the testing instrument 15. The automatic lifting device 14 includes a lifting cylinder 141, second guide columns 142, and a lifting platform 143. The lifting cylinder 141 and multiple second guide columns 142 are fixedly mounted on the fixed platform 1. The lifting platform 143 is fixedly connected to the output end of the lifting cylinder 141 and can be driven by the lifting cylinder 141 to move up and down along the second guide columns 142. The testing instrument 15 is fixedly mounted on the lifting platform 143 and can be driven by the lifting cylinder 141 to enter or leave the testing position.

[0086] By setting up an automatic lifting device 14, the testing instrument 15 can be automatically transported to the desired position when testing is required. At the same time, when it is necessary to switch to another output channel 81, the testing instrument 15 can be automatically transported away from the cabin 7 to avoid interference.

[0087] The working process of this device is as follows: When the control device 8 needs to be tested, the cabin 7 is first installed on the cabin rotating base 4, and then the control device 8 is installed inside the cabin 7. The rotation angle of the cabin rotating base 4 is controlled by the servo motor 9. After rotating into place, the first guide post 132 of the automatic correction device 13 is aligned and automatically inserted into the correction hole on the side of the cabin rotating base 4 to achieve automatic alignment and initial locking of the cabin 7. Then, the automatic tightening device 12 automatically tightens the middle adjusting screw 32 of the locking parts 3 on both sides of the cabin rotating base 4, so that the pressure blocks at both ends press the cabin rotating base 4, achieving rapid and reliable locking of the cabin 7, so that the product is ready for performance testing.

[0088] The installation height of the testing instrument 15 is automatically adjusted and locked by the automatic lifting device 14. Then, the control device 8 and the testing instrument 15 are connected to perform the test. The locking component 3 ensures that the control device 8 is not affected by vibration during the test and remains in its original position.

[0089] When the control device 8 completes the test of one output channel 81 and needs to switch to another output channel 81, the calibration cylinder 131 of the automatic calibration device 13 retracts, and the first guide post 132 disengages from the rotating base 4 of the chamber. Then, the test instrument 15 and the control device 8 are disconnected. The automatic tightening device 12 releases the force on the middle adjusting screw 32 of the locking component 3 and loosens it, allowing the pressure block 31 to be in a free state. The rotating base 4 of the chamber is now unlocked and can rotate. The servo motor 9 controls the rotating shaft 5 again, driving the chamber 7 and the control device 8 to rotate, adjusting the output channel 81 of the control device 8 to the test position. The automatic calibration device 13 then corrects the position of the rotating base 4 of the chamber and initially locks it.
