Description

Technical Field

[0001] This invention relates to the field of directed energy equipment technology, and more specifically to the field of four-way valve and turntable matching and docking methods. Background Technology

[0002] The beam control and directional emission system is an important component of laser directional energy equipment. Its function is to quickly acquire and stably track the target, and to accurately and stably focus high-energy lasers onto the target to achieve damage.

[0003] The launch tube and turntable are important components of a beam control and directional emission system. The launch tube enables the directional emission and focusing of a high-energy laser beam from a laser source onto a designated target location. The launch tube interacts with the control system to achieve high-precision tracking and aiming control of moving targets. The four-way connector is the main load-bearing frame of the launch tube, on which various precision equipment is mounted, requiring very high precision. The four-way connector is connected to the turntable via a pitch axis system, with a clearance between the four-way connector and the turntable at the micrometer level. The four-way connector and the turntable weigh several tons, and their surfaces are coated with special materials, requiring adequate protection during assembly and achieving very high control precision. This places higher demands on the fit and docking method between the four-way connector and the turntable. This invention proposes a fit and docking method for the four-way connector and the turntable that can meet the high-precision requirements of the docking. Summary of the Invention

[0004] The purpose of this invention is to provide a method for cooperating and connecting a four-way valve with a turntable in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] This invention provides a method for mating and connecting a four-way valve with a turntable, comprising the following steps:

[0007] Preparation of S1, four-way valve, turntable, auxiliary tooling, and testing tools: Auxiliary tooling includes support tooling, jacks, guide rods, and overhead crane; testing tools include photoelectric autocollimator, electronic level, and theodolite;

[0008] S2. Secure the support fixture to the seismic isolation foundation using fasteners and adjust it to be level;

[0009] S3. The turntable is hoisted onto the support fixture by the overhead crane and fixed with fasteners. Then, a level is placed above the turntable. By adjusting the support fixture, the turntable is leveled. The turntable itself can rotate 360 ​​degrees in the azimuth direction through the azimuth axis system.

[0010] S4, guide rod and jack help to connect the four-way valve to the turntable with fasteners, the four-way valve can be rotated 360 degrees through the pitch axis system;

[0011] S5. Measure the azimuth axis wobbling of the turntable, the pitch axis wobbling of the four-way connector, and the angular deviation of the reference mirrors on both sides of the four-way connector to complete the mating and docking of the four-way connector with the turntable.

[0012] In one embodiment, in step S4, the turntable includes a turntable body, a U-shaped frame, a left column, a right column, a left docking flange, and a right docking flange. The left column and the right column are respectively connected to the two side wall ends of the U-shaped frame with fasteners. The left docking flange and the right docking flange are respectively connected to the left column and the right column with fasteners. Then, a level is placed above the U-shaped frame, and the turntable is adjusted to be level by adjusting the support fixture.

[0013] In one embodiment, the hole tolerance between the left column and the left mating flange is H5, and the corresponding hole tolerance of the left mating flange is g5.

[0014] In one embodiment, the tolerance of the mating hole between the right column and the right mating flange is H5, and the corresponding tolerance of the right mating flange hole is g5.

[0015] Specifically, the left and right mating flanges are fitted with the left and right columns respectively with small clearance fits. The diameter of the holes and shafts is several hundred millimeters, and the weight is several tons. The advantage of this assembly is that it can be assembled at room temperature and can be assembled and disassembled multiple times. The small clearance fit can achieve a very high rotational error when the four-way valve rotates, so as to meet the high precision requirements of the equipment.

[0016] In one implementation, in step 4: the left column is then disassembled, moved to the left, and secured with fasteners. The tee is then lifted by the overhead crane and connected to the right connecting flange. The two connection holes of the right connecting flange and the right column are used and secured with fasteners. Two guide rods are then passed through the right column and connected to the tee to act as guides. A force is applied to the left side of the tee to the right to ensure that the tee and the right connecting flange are properly connected. At this point, the tee falls onto the four sets of jacks on the U-shaped frame, which are used to fine-tune the tee so that the guide rods are connected to the tee. Then, the fasteners of the right connecting flange and the right column are installed. At this point, the two guide rods are removed, and the fasteners of the connection hole are installed.

[0017] In one embodiment, the left column is then lifted by an overhead crane, bringing the crane into a pre-tightening state. The fasteners that originally fixed the left column are removed, and a force is applied on the other side of the left column to connect with the four-way connector, thereby connecting the left column and the four-way connector together. Then, the left column and the four-way connector are connected together by fasteners.

[0018] In one embodiment, in step 5, the azimuth axis sway is measured: an electronic level is placed on the upper end of the U-shaped frame, the azimuth axis is rotated one revolution at a certain angle, and the electronic level readings at each corresponding angular position of the azimuth axis are recorded. The electronic level is then placed at another position on the upper end of the U-shaped frame, and the measurement is performed in the same way.

[0019] In one embodiment, in step 6, the oscillation of the turntable's orientation axis is measured: an electronic level is placed on the upper end of the U-shaped frame, the orientation axis of the turntable rotates one revolution every set angle, and the electronic level readings at each corresponding angular position of the orientation axis are recorded. The electronic level is then placed at another position on the upper end of the U-shaped frame, and the measurement is performed in the same way.

[0020] In one embodiment, in step 6, the wobbling of the four-way pitch axis system is measured: a plane mirror is installed at one end of the four-way system and placed close to the rotation axis. The photoelectric autocollimator is placed and adjusted to the same height as the plane mirror to ensure that the autocollimator support is stable and does not wobble. The perpendicularity of the mirror relative to the pitch axis is adjusted, and the pitch axis is slowly rotated until the difference in readings of the photoelectric autocollimator is the smallest within one rotation of the pitch axis. The pitch axis rotates one revolution every set angle, and the corresponding value of the photoelectric autocollimator is recorded.

[0021] In one embodiment, in step 6, the angular deviation of the reference mirrors on both sides of the four-way is measured: the theodolite is placed and adjusted to the same height as the center of the reference mirror, ensuring that the autocollimator support is stable and does not shake; the perpendicularity of the reflector relative to the pitch axis is adjusted, and the pitch axis is slowly rotated until the theodolite has the smallest reading difference within one rotation of the pitch axis. The pitch axis rotates once every set angle, and the theodolite value is recorded.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention is reasonably designed. By using auxiliary tooling to assist in the installation of the turntable and the four-way connector, it measures the azimuth axis wobble of the turntable, the pitch axis wobble of the four-way connector, and the angular deviation of the reference mirrors on both sides of the four-way connector, thus meeting the high-precision requirements for docking the four-way connector and the turntable.

[0024] 2. The left and right mating flanges are fitted with the left and right columns respectively with small clearance fits. The diameter of the holes and shafts is several hundred millimeters, and the weight is several tons. The advantage of this assembly is that it can be assembled at room temperature and can be assembled and disassembled multiple times. The small clearance fit can achieve a very high rotational error when the four-way valve rotates, so as to meet the high precision requirements of the equipment. Attached Figure Description

[0039] Preparation of S1, four-way connector 6, turntable, auxiliary tooling, and testing tools: Auxiliary tooling includes support tooling 1, jack 9, guide rod 4, and overhead crane; testing tools include photoelectric autocollimator 10, electronic level, and theodolite;

[0040] S2. Secure the support fixture 1 to the seismic isolation foundation using fasteners and adjust it to be horizontal;

[0041] S3. The turntable is hoisted onto the support fixture 1 by the overhead crane and fixed with fasteners. Then, a level is placed above the turntable. By adjusting the support fixture 1, the turntable is leveled. The turntable itself can rotate 360 ​​degrees in the azimuth direction through the azimuth axis system.

[0042] S4, guide rod 4 and jack 9 assist in connecting the four-way connector 6 to the turntable with fasteners. The four-way connector 6 can rotate 360 ​​degrees through the pitch axis system.

[0043] S5. Measure the azimuth axis wobbling of the turntable, the pitch axis wobbling of the four-way connector 6, and the angular deviation of the reference mirrors 11 on both sides of the four-way connector 6 to complete the mating and docking of the four-way connector 6 with the turntable.

[0046] In step S4, the turntable includes a turntable body, a U-shaped frame 2, a left column 8, a right column 3, a left mating flange 7, and a right mating flange 5. The left column 8 and right column 3 are fastened to the two ends of the side walls of the U-shaped frame 2, respectively. The left mating flange 7 and right mating flange 5 are fastened to the left column 8 and right column 3, respectively. Then, a level is placed above the U-shaped frame 2, and the turntable is leveled by adjusting the support fixture 1. Figure 2 As shown.

[0047] Example 3

[0048] This implementation is a further optimization based on Example 2, specifically:

[0049] The tolerance of the hole for the left column 8 and the left mating flange 7 is H5, and the corresponding tolerance of the hole for the left mating flange is g5.

[0050] The tolerance of the mating hole between the right column 3 and the right mating flange 5 is H5, and the corresponding tolerance of the right mating flange hole is g5.

[0051] Specifically, the left and right mating flanges 5 are fitted with the left column 8 and right column 3 respectively with small clearance fits. The diameter of the holes and shafts is several hundred millimeters, and the weight is several tons. The advantage of this assembly is that it can be assembled at room temperature and can be assembled and disassembled multiple times. The small clearance fit can achieve a very high rotational error when the four-way 6 rotates, so as to meet the high precision requirements of the equipment.

[0052] Example 4

[0053] This implementation is a further optimization based on Example 3, specifically:

[0054] In step 4; then disassemble the left column 8, move it to the left and fix it with fasteners. Use the overhead crane to lift the four-way connector 6 and connect it with the right connecting flange 5. Use the two connection holes of the right connecting flange 5 and the right column 3 and tighten them with fasteners. Then, use two guide rods 4 to pass through the right column 3 and connect to the four-way connector 6 to guide it. Apply a rightward force to the left side of the four-way connector 6 to make the four-way connector 6 and the right connecting flange 5 connect in place. At this time, the four-way connector 6 falls onto the four sets of jacks 9 on the U-shaped frame 2 to fine-tune the four-way connector 6 so that the guide rods 4 are connected to the four-way connector 6. Then install the fasteners of the right connecting flange 5 and the right column 3. At this time, disassemble the two guide rods 4 and then install the fasteners of the connection hole. Figure 3 .

[0055] Then, the left column 8 is lifted by the gantry crane, bringing it to a pre-tensioning state. The fasteners that originally secured the left column 8 are removed. A force is applied on the other side of the left column 8 where it connects to the four-way connector 6, causing the left column 8 and the four-way connector 6 to align. The left column 8 and the four-way connector 6 are then connected together using fasteners. Figure 4 As shown.

[0056] Example 5

[0057] This implementation is a further optimization based on Example 3, specifically:

[0058] In step 5, measure the azimuth axis sway: Place an electronic level on the upper end of U-shaped frame 2, rotate the azimuth axis one revolution at certain angles, and record the electronic level readings at the corresponding angular positions. Place the electronic level at another position on the upper end of U-shaped frame 2 and measure using the same method. Figure 5 As shown.

[0059] Example 5

[0060] This implementation is a further optimization based on Example 3, specifically:

[0061] In step 6, measure the oscillation of the turntable's orientation axis: place an electronic level on the upper end of the U-shaped frame 2, rotate the orientation axis of the turntable one revolution every set angle, record the electronic level readings at the corresponding angular positions of the orientation axis, place the electronic level at another position on the upper end of the U-shaped frame 2, and measure in the same way.

[0062] In step 6, the pitch axis wobbling of the four-way connector 6 is measured: a plane mirror is installed at one end of the four-way connector 6, close to the rotation axis. The photoelectric autocollimator 10 is placed and adjusted to the same height as the plane mirror, ensuring the autocollimator support is stable and without wobbling. The perpendicularity of the mirror relative to the pitch axis is adjusted, and the pitch axis is slowly rotated until the reading difference of the photoelectric autocollimator 10 is minimized within one revolution of the pitch axis. The pitch axis rotates one revolution at every set angle, and the corresponding value of the photoelectric autocollimator 10 is recorded. Figure 6 As shown.

[0063] In step 6, measure the angular deviation of the reference mirrors 11 on both sides of the four-way connector 6: Place the theodolite and adjust it to the same height as the center of the reference mirror 11, ensuring the autocollimator support is stable and without shaking; adjust the perpendicularity of the reflecting mirror relative to the pitch axis, and slowly rotate the pitch axis until the theodolite's reading difference is minimal within one revolution of the pitch axis. Record the theodolite's values ​​every set angle revolution of the pitch axis. Figure 7 As shown.
