Description

Technical Field

[0001] This application relates to the field of precision testing technology, and more specifically, to a launcher follow-up precision testing device and testing method. Background Technology

[0002] A launcher is a specialized device for suspending and launching missiles. In actual use, the accuracy of the launcher needs to be adjusted and tested frequently to ensure its accuracy during later use, thereby ensuring the accuracy of the final weapon launch.

[0003] However, the applicant believes that traditional accuracy testing devices have the following drawbacks: due to the long launch distance, a small error can lead to a large error. Therefore, during accuracy testing, special attention needs to be paid to the servo accuracy of the launcher. However, traditional testing accuracy is low, which leads to a large error in the test results of the launcher's servo accuracy. Summary of the Invention

[0004] To improve the detection accuracy of launcher servo accuracy testing, this application provides a launcher servo accuracy testing device and testing method.

[0005] Firstly, the launcher servo accuracy detection device provided in this application adopts the following technical solution:

[0006] A transmitter servo accuracy detection device includes a first mounting frame, on which a mounting shaft is rotatably mounted, and at the top end of the mounting shaft is a mounting part, which is detachably connected to the mounting shaft. A signal transmitting device is mounted on the mounting part. The device also includes a response component, which includes a second mounting frame, on which a signal receiving device is mounted. The signal receiving device is adapted to the signal transmitting device.

[0007] Optionally, the signal transmitting device is configured as a micrometer, which is fixedly mounted on the mounting part. A limiting member is provided on the mounting part to limit the position of the mounting part on the mounting shaft.

[0008] By adopting the above technical solution, when it is necessary to disassemble the mounting part, the limitation of the mounting part on the mounting shaft by the limiting component is first released, and the mounting part can be disassembled. This makes it convenient for the staff to carry the equipment in parts, and has a good protective effect on precision instruments such as micrometers. It can effectively ensure that the follow-up accuracy of the launcher can be accurately detected in the next accuracy test.

[0009] Optionally, a slot is provided on the mounting shaft along the vertical direction, the top of the slot is open, and an insert block is slidably disposed in the slot along the length of the slot. The insert block is fixedly connected to the mounting part, and the limiting member is used to limit the position of the insert block in the slot.

[0010] By adopting the above technical solution, in actual use, the limiting component first removes the restriction on the position of the insert block in the slot, and then the insert block can be driven to move in the slot, thereby achieving the purpose of driving the installation part to move. During this process, the side wall of the insert block is always in contact with the inner wall of the slot, which can effectively guide the movement of the installation part on the installation shaft and improve the overall reliability of the device during use.

[0011] Optionally, the limiting member is configured as a limiting pin, the side wall of the mounting part is provided with a mounting hole through which the insert block passes, the slot is provided with a limiting hole for the insertion of the limiting pin, and the mounting part is provided with a first elastic member for driving the limiting pin to move toward the slot.

[0012] By adopting the above technical solution, when it is necessary to release the restriction of the insertion block's position in the slot, the limiting pin is first driven to move away from the mounting hole. When the end of the limiting pin disengages from the limiting hole, the restriction of the insertion block's position by the limiting pin is released. The operation is convenient and quick. In subsequent use, the limiting pin always tends to move towards the slot under the action of the first elastic element, avoiding the limiting pin from disengaging due to accidental human contact or machine vibration during normal operation of the equipment, thus improving the reliability of the device in actual use.

[0013] Optionally, the insert block is provided with balls that roll in contact with the inner wall of the slot.

[0014] By adopting the above technical solution, when the insert block moves in the slot, the sliding friction between the insert block and the inner wall of the slot is changed into rolling friction by the ball bearings, which effectively reduces the friction coefficient between the insert block and the inner wall of the slot, thereby effectively reducing the friction force between the insert block and the inner wall of the slot, facilitating the movement of the insert block in the slot, and also effectively reducing the wear between the insert block and the inner wall of the slot, thus improving the service life of the device.

[0015] Optionally, an installation groove is formed on the inner wall of the slot along the length direction of the slot, and an abutment block is slidably disposed in the installation groove along the length direction perpendicular to the slot. The end of the abutment block away from the installation groove abuts against the side wall of the insert. A second elastic element is provided in the installation groove, which is used to drive the abutment block to move away from the installation groove. An anti-detachment component is provided in the installation groove, which is used to prevent the abutment block from detaching from the installation groove.

[0016] By adopting the above technical solution, in actual use, after the insert block is inserted into the slot, the side wall of the insert block abuts against the side wall of the abutting block. Under the action of the second elastic element, the abutting block tends to move away from the mounting slot, thereby limiting the position of the insert block in the slot, improving the installation stability and installation accuracy of the mounting part on the mounting shaft, and improving the overall service life of the device.

[0017] Optionally, the abutment block has a slot on the side near the top opening of the slot, and the end of the slot away from the mounting slot is set as an inclined surface. The side wall of the insert block has a locking block for locking into the slot.

[0018] By adopting the above technical solution, in actual use, after the insert block is inserted into the slot, the side wall of the insert block abuts against the abutting block, and the insert block drives the locking block into the slot. This can further limit the position of the insert block in the slot, and further improve the reliability and practicality of the device in use.

[0019] Optionally, the anti-detachment component is configured as an anti-detachment block, and an anti-detachment groove is provided on the side wall of the mounting groove along the sliding direction of the abutment block. The anti-detachment block is slidably disposed in the anti-detachment groove, and the end of the anti-detachment block away from the anti-detachment groove is fixedly connected to the abutment block.

[0020] By adopting the above technical solution, in actual use, the anti-detachment block can effectively prevent the abutment block from detaching from the installation groove, avoiding the need for secondary installation of the abutment block after the installation part is disassembled, reducing the workload of the staff, and having good practicality and reliability.

[0021] Optionally, a buffer pad is fixedly provided on the side wall of the anti-detachment block, and the buffer pad is used to abut against the side wall of the anti-detachment groove.

[0022] Secondly, the launcher servo accuracy detection method provided in this application adopts the following technical solution:

[0023] A method for detecting the servo accuracy of a launcher, using the detection device described above, includes the following steps:

[0024] Based on the required detection accuracy, select a micrometer with suitable accuracy and fix the micrometer on the mounting part. Move the mounting part to the mounting shaft and use the signal receiving device to initially detect the initial position of the micrometer as S1, and record the initial rotation position of the mounting shaft as K1.

[0025] The mounting shaft rotates, which in turn drives the mounting part and ultimately the micrometer to rotate. After the rotation ends, the movement position of the micrometer is detected by the signal receiving device and recorded as S2, and the rotation termination position of the mounting shaft is recorded as K2.

[0026] Calculate the difference between S1 and S2 and record it as S3. Calculate the difference between K1 and K2 and record it as K3. Compare the difference between S3 and K3 to obtain the rotation error of the mounting shaft.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The rotation angle of the mounting shaft is magnified and calculated using a micrometer, and the error of the mounting shaft rotation is obtained through more accurate angle measurement. The calculation is more accurate and reliable, and saves a lot of manpower and material resources, making it highly practical. Attached Figure Description

[0043] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0044] Example

[0045] In a first aspect, embodiments of this application disclose a launcher follow-up accuracy detection device.

[0046] Reference Figure 1 A transmitter servo accuracy detection device includes a first mounting frame 1, on which a mounting shaft 11 is rotatably mounted, and a mounting part 12 is provided at the top end of the mounting shaft 11. The mounting part 12 is detachably connected to the mounting shaft 11, and a signal transmitting device 13 is provided on the mounting part 12. The device also includes a response component 2, which includes a second mounting frame 21. A signal receiving device 22 is provided on the second mounting frame 21, and the signal receiving device 22 is adapted to the signal transmitting device 13.

[0047] As one embodiment of this application, refer to Figure 1 The signal transmitting device 13 is a micrometer, which is fixedly mounted on the mounting part 12. The mounting part 12 is provided with a limiting member 3, which is used to limit the position of the mounting part 12 on the mounting shaft 11.

[0048] When it is necessary to disassemble the mounting part 12, first release the limiting part 3 from restricting the position of the mounting part 12 on the mounting shaft 11, and then the mounting part 12 can be disassembled. This makes it convenient for staff to carry the equipment in parts, and provides good protection for precision instruments such as micrometers. It can effectively ensure that the follow-up accuracy of the launcher can be accurately detected in the next accuracy test.

[0049] Among them, reference Figure 2 , 3 A slot 31 is provided on the mounting shaft 11 along the vertical direction. The top of the slot 31 is open. A plug 32 is slidably disposed inside the slot 31 along the length of the slot 31. The plug 32 is fixedly connected to the mounting part 12. The limiting member 3 is used to limit the position of the plug 32 inside the slot 31.

[0050] In actual use, the limiting member 3 first releases the restriction on the position of the insert 32 in the slot 31, and then the insert 32 can be driven to move in the slot 31, thereby achieving the purpose of driving the mounting part 12 to move. During this process, the side wall of the insert 32 always abuts against the inner wall of the slot 31, which can effectively guide the movement of the mounting part 12 on the mounting shaft 11, improving the overall reliability of the device during use.

[0051] As one embodiment of this application, refer to Figure 2 , 3 The limiting member 3 is set as a limiting pin. The mounting part 12 has a mounting hole 33 on its side wall. The mounting hole 33 passes through the insert block 32. The slot 31 has a limiting hole 34 for the insertion of the limiting pin. The mounting part 12 is provided with a first elastic member 35 for driving the limiting pin to move toward the slot 31.

[0052] In one embodiment of this application, the first elastic element 35 is configured as a tension spring, which is sleeved on the limiting pin. One end of the tension spring is fixedly connected to the limiting pin, and the other end is fixedly connected to the mounting part 12.

[0053] When it is necessary to release the position restriction of the insert 32 in the slot 31, the limiting pin is first driven to move away from the mounting hole 33. When the end of the limiting pin is disengaged from the limiting hole 34, the limitation of the position of the insert 32 by the limiting pin is released. The operation is convenient and quick. In subsequent use, the limiting pin always tends to move towards the slot 31 under the action of the first elastic element 35, which avoids the limiting pin from disengaging due to human error or machine vibration during normal operation of the equipment, thus improving the reliability of the device in actual use.

[0054] Among them, reference Figure 3 The insert 32 is provided with a ball 36 that makes rolling contact with the inner wall of the slot 31.

[0055] As the insert moves within the slot, the rolling balls transform the sliding friction between the insert and the inner wall of the slot into rolling friction, effectively reducing the coefficient of friction between the insert and the inner wall of the slot. This, in turn, reduces the frictional force between the insert and the inner wall of the slot, facilitating the movement of the insert within the slot. It also effectively reduces wear between the insert and the inner wall of the slot, thus improving the service life of the device.

[0056] Reference Figure 3 , 4An installation groove 4 is provided on the inner wall of the slot 31 along the length direction of the slot 31. An abutment block 41 is slidably disposed in the installation groove 4 along the length direction perpendicular to the slot 31. The end of the abutment block 41 away from the installation groove 4 abuts against the side wall of the insert block 32. A second elastic member 42 is provided in the installation groove 4. The second elastic member 42 is used to drive the abutment block 41 to move away from the installation groove 4. An anti-detachment component 5 is provided in the installation groove 4. The anti-detachment component 5 is used to prevent the abutment block 41 from detaching from the installation groove 4.

[0057] As one embodiment of this application, refer to Figure 4 , 5 The second elastic element 42 is configured as a compression spring, which is located in the mounting groove 4. One end of the compression spring is fixedly connected to the inner wall of the mounting groove 4, and the other end is fixedly connected to the abutment block 41.

[0058] In actual use, after the insert 32 is inserted into the slot 31, the side wall of the insert 32 abuts against the side wall of the abutment block 41. Under the action of the second elastic member 42, the abutment block 41 tends to move away from the mounting slot 4, thereby limiting the position of the insert 32 in the slot 31, improving the installation stability and installation accuracy of the mounting part 12 on the mounting shaft 11, and improving the overall service life of the device.

[0059] Reference Figure 4 , 5 A slot 43 is provided on the side of the abutment block 41 near the top opening of the slot 31. The end of the slot 43 away from the mounting slot 4 is set as an inclined surface. A block 44 is provided on the side wall of the insert block 32. The block 44 is used to be inserted into the slot 43.

[0060] In actual use, after the insert 32 is inserted into the slot 31, the side wall of the insert 32 abuts against the abutment block 41, and the insert 32 drives the locking block 44 to lock into the slot 43. This can further limit the position of the insert 32 in the slot 31, and further improve the reliability and practicality of the device during use.

[0061] Reference Figure 5 As one embodiment of this application, the anti-detachment component 5 is configured as an anti-detachment block 51. An anti-detachment groove 52 is provided on the side wall of the mounting groove 4 along the sliding direction of the abutment block 41. The anti-detachment block 51 is slidably disposed in the anti-detachment groove 52, and the end of the anti-detachment block 51 away from the anti-detachment groove 52 is fixedly connected to the abutment block 41.

[0062] In actual use, the anti-detachment block 51 can effectively prevent the abutment block 41 from detaching from the mounting groove 4, avoiding the need to reinstall the abutment block 41 after the mounting part 12 is disassembled, reducing the workload of the staff, and has good practicality and reliability.

[0063] Among them, reference Figure 5 A buffer pad 53 is fixedly installed on the side wall of the anti-detachment block 51, and the buffer pad 53 is used to abut against the side wall of the anti-detachment groove 52.

[0064] Secondly, this application discloses a method for detecting the servo accuracy of a launcher.

[0065] A method for detecting the servo accuracy of a launcher, using the detection device described above, includes the following steps:

[0066] According to the required detection accuracy, select a micrometer with suitable accuracy and fix the micrometer on the mounting part 12, drive the mounting part 12 to be mounted on the mounting shaft 11, and record the initial position of the micrometer by the signal receiving device 22 as S1, and record the initial rotation position of the mounting shaft 11 as K1.

[0067] The mounting shaft 11 is driven to rotate, which in turn drives the mounting part 12 and ultimately the micrometer to rotate. After the rotation ends, the movement position of the micrometer is detected by the signal receiving device 22 and recorded as S2, and the rotation termination position of the mounting shaft 11 is recorded as K2.

[0068] The difference between S1 and S2 is calculated and recorded as S3, the difference between K1 and K2 is calculated and recorded as K3, and the difference between S3 and K3 is compared to obtain the rotation error of the mounting shaft 11.

[0069] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
