Description

Technical Field

[0001] This invention relates to the field of welding facilities, and more particularly to a welding fixture for missile launcher assembly. Background Technology

[0002] Missile launchers are core equipment of modern weapon systems, responsible for carrying, aiming, and launching various types of missiles. The performance of missile launchers directly affects combat effectiveness. During the manufacturing process, missile launchers primarily rely on welding equipment to provide crucial process support, ensuring structural strength and stability.

[0003] The missile launcher needs to be connected with a hydraulic cylinder to achieve the angle adjustment function of the launcher. In order to facilitate the subsequent assembly of the hydraulic cylinder and the launcher, lugs are usually welded simultaneously during the assembly welding process of the missile launcher. However, the current lug welding relies on manual measurement and positioning by the staff. This operation method is prone to positioning errors, which leads to the positional displacement of the lugs after welding, and ultimately has an adverse effect on the subsequent assembly of the hydraulic cylinder. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a missile launcher assembly welding fixture.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a missile launcher welding fixture, comprising a fixture frame, a positioning component mounted on the upper end of the fixture frame, a concave carrier frame disposed on the side of the positioning component, a connecting rod disposed on the upper part of both ends of the concave carrier frame, the distance between the two ends of the concave carrier frame being adapted to the distance between two sets of lugs on the launcher frame, a connecting claw seat rotatably mounted on the middle of the outer surface of the connecting rod, and two positioning claws symmetrically disposed at the front and rear ends of the concave carrier frame, the positioning claws being inclined, the lower positioning claw being fixed to the concave carrier frame, and the upper positioning claw being fixed to the concave carrier frame. The positioning claw is fixed to the connecting claw seat. Fixed magnets are embedded through the front and rear end faces of the concave frame. The fixed magnets correspond to the space between the two positioning claws. A threaded column is rotatably installed at the middle of the lower end of the concave frame. A movable frame is screwed onto the outer surface of the threaded column. Slot joints are slidably installed inside both ends of the concave frame. The slot joints are connected to the movable frame. A release claw frame is rotatably installed on the inner side of the slot joint. The release claw frame extends from the inner side of the slot joint. A double-headed frame is rotatably installed at the end of the release claw frame. The end of the double-headed frame is fixed to the lower side of the connecting claw seat.

[0006] Preferably, both ends of the connecting rod are fixedly installed with rod frames, the ends of the rod frames are fixed to the concave carrier, the lower end of the slot joint is fixedly installed with a guide post, the guide post extends through the lower end of the concave carrier, the guide post slides with the concave carrier, and the lower end of the guide post is fixed to the movable frame.

[0007] Preferably, the positioning component includes a rear upright fixedly installed at the center of the upper rear edge of the tooling frame, a front upright fixedly installed at the center of the upper front edge of the tooling frame, a T-shaped guide plate fixedly installed at the upper end of the front upright, the rear end of the T-shaped guide plate being fixed to the rear upright, and transverse positioning slots provided on the outer surface of the T-shaped guide plate and the upper end of the rear upright. The rear upright has one transverse positioning slot and is fixedly connected to the rear upright, while the T-shaped guide plate has three transverse positioning slots and is slidably connected to the T-shaped guide plate. The spacing between the four transverse positioning slots is adapted to the spacing between the four crossbeams of the launcher.

[0008] Preferably, a seat bracket is provided on the side of the rear support frame, the lower end of the seat bracket is fixed to the tooling frame, and three positioning supports are linearly arrayed and fixedly installed on the upper end of the seat bracket. The distribution of the positioning slots on the three positioning supports is adapted to the distribution of multiple reinforcing frames on the launcher. Two connecting frames extend symmetrically from the side of the seat bracket, and the ends of the connecting frames are fixed to the concave carrier frame.

[0009] Preferably, two longitudinal positioning slots are provided above the tooling frame, and the distance between the two longitudinal positioning slots is adapted to the distance between the two vertical frames of the launcher. The concave carrier, positioning bracket, and transverse positioning slot are located between the two longitudinal positioning slots. The two ends of the concave carrier are symmetrical about the center line of the longitudinal positioning slot. The lower end of one of the longitudinal positioning slots is fixed to the tooling frame, and the other longitudinal positioning slot is slidably connected to the concave carrier. A top solid is provided on the front upright.

[0010] Preferably, the lower end of another longitudinal positioning bracket extends symmetrically with two T-shaped sliders, the outer surface of which is slidably fitted with a T-shaped groove, and the end of the T-shaped groove is fixed to the concave carrier.

[0011] Preferably, the top support includes a threaded rod that is rotatably mounted on the upper side of the front upright. A threaded sleeve is screwed onto the outer surface of the threaded rod. A top support extends from the upper end of the threaded sleeve. The end of the top support is fixed to the lower end of another longitudinal positioning slot. A reinforcing frame is rotatably mounted on the end of the threaded rod. The end of the reinforcing frame is fixed to the front upright.

[0012] Preferably, the front end of the top-supporting frame extends into a protruding frame, and the end of the protruding frame is rotatably mounted with a top-supporting connecting rod. The lower side of the transverse positioning slot located at the front edge of the T-shaped guide plate extends into a connecting lug, and the end of the top-supporting connecting rod is rotatably connected to the end of the connecting lug.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Place two lugs at the front and back of one end of the concave carrier. At this time, two positioning claws will engage with the upper and lower ends of the lugs respectively. Simultaneously, fix the lugs with magnets to attract and fix them, aligning the mounting holes on the two lugs. Similarly, place the other set of two lugs at the front and back of the other end of the concave carrier and fix them. This completes the positioning of the two sets of lugs. This process replaces manual measurement and positioning by the staff, effectively avoiding positioning errors and preventing the lugs from shifting after welding. This ensures the smooth assembly of the launcher and hydraulic cylinder. After welding, rotating the threaded column can drive the slotted joint on the moving frame to move down, thereby driving the loosening claw frame to move and pull the double-headed frame. This allows the connecting claw seat to rotate around the connecting rod, thereby lifting the upper positioning claw to disengage from the lugs. This allows the welded launcher to be lifted and removed smoothly, facilitating the unloading after welding.

[0015] 2. Position the two vertical frames of the launcher in the two longitudinal positioning slots, and position the four horizontal frames in the four transverse positioning slots. Position the multiple reinforcing frames in the positioning slots on the three positioning supports. This allows all parts of the launcher to be positioned at once, enabling continuous welding and avoiding the need to position and weld the next part after welding one part, thus improving welding convenience.

[0016] 3. By rotating the threaded rod, the threaded sleeve can be moved, which in turn moves the top support frame, pushing the longitudinal positioning slot towards another longitudinal positioning slot. This causes the vertical frame of the launcher to push against the horizontal frame, making them fit tightly together. It also ensures that the vertical frame and the lug of the launcher fit tightly together. At the same time, the moving top support frame will also drive the top support connecting rod to move, pushing the foremost horizontal positioning slot. This, in turn, causes the foremost horizontal frame to move backward, pushing against the horizontal frame and the reinforcing frame, making the horizontal frame and the reinforcing frame of the launcher fit tightly together. This ensures that all parts of the launcher fit tightly together after positioning, thus guaranteeing welding quality. Attached Figure Description

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] like Figures 1-12The missile launcher assembly welding fixture shown includes a fixture frame 1. A positioning component is mounted on the upper end of the fixture frame 1, and a concave carrier 19 is provided on the side of the positioning component. The concave carrier 19 serves as a load-bearing component. Connecting rods 20 are provided on the upper part of both ends of the concave carrier 19. The distance between the two ends of the concave carrier 19 is adapted to the distance between the two sets of lugs 32 on the launcher 31, ensuring that the distance between the two sets of lugs 32 positioned by the two ends of the concave carrier 19 meets the processing requirements of the launcher 31. A connecting claw seat 24 is rotatably mounted on the middle of the outer surface of the connecting rod 20, and the connecting rod 20 serves to allow the connecting claw seat 24 to rotate. Two positioning tops are symmetrically provided at the front and rear of the ends of the concave carrier 19. The positioning claw 18 is inclined to accommodate the upper and lower inclined surfaces of the lug 32 for positioning. The lower positioning claw 18 is fixed to the concave carrier 19 and can engage with the upper and lower ends of the lug 32 for positioning, aligning the mounting holes of the two lugs 32. The upper positioning claw 18 is fixed to the connecting claw seat 24. Fixed magnets 17 are embedded through the front and rear ends of the concave carrier 19, corresponding to the two positioning claws 18. The fixed magnets 17 attract and fix the positioned lug 32. When the two lugs 32 are placed at the front and rear of one end of the concave carrier 19, the two positioning claws 18 engage with the upper and lower ends of the lug 32 respectively. At the same time, the magnet 17 is fixed to attract and fix the lug 32, aligning the mounting holes on the two lugs 32. Similarly, the two lugs 32 of the other set are placed and fixed at the front and rear of the other end of the concave frame 19, thus completing the positioning of the two sets of lugs 32. This process replaces manual measurement and positioning by the staff, effectively avoiding positioning errors and preventing the lugs 32 from shifting after welding. This ensures the smooth assembly of the launcher 31 and the hydraulic cylinder 34. A threaded post 26 is rotatably installed in the middle of the lower end of the concave frame 19. A movable frame 27 is screwed onto the outer surface of the threaded post 26. Slot joints 29 are slidably installed inside both ends of the concave frame 19, and the slot joints 29 serve as connections. The slotted joint 29 is connected to the movable frame 27. The inner side of the slotted joint 29 is inclined and rotatably mounted with a release claw bracket 22. The release claw bracket 22 extends from the inner side of the slotted joint 29. The end of the release claw bracket 22 is rotatably mounted with a double-headed bracket 23. The end of the double-headed bracket 23 is fixed to the lower side of the connecting claw seat 24. After welding, rotating the threaded column 26 can drive the slotted joint 29 on the movable frame 27 to move down, thereby driving the release claw bracket 22 to move and pull the double-headed bracket 23, so that the connecting claw seat 24 can rotate around the connecting rod 20, thereby lifting the upper positioning claw 18 to disengage from the lug 32, so that the welded launcher 31 can be lifted and removed smoothly, thus facilitating the unloading after welding.

[0032] Both ends of the connecting rod 20 are fixedly installed with rod brackets 21. The ends of the rod brackets 21 are fixed to the concave carrier 19. The rod brackets 21 serve to fix the connecting rod 20. The lower end of the slot joint 29 is fixedly installed with a guide post 28. The guide post 28 extends through the lower end of the concave carrier 19 and slides with the concave carrier 19. The lower end of the guide post 28 is fixed to the movable frame 27. The guide post 28 can guide the movable frame 27 on the one hand, and connect the slot joint 29 and the movable frame 27 together on the other hand.

[0033] The positioning components include a rear upright 2 fixedly installed at the center of the upper rear edge of the tooling frame 1, a front upright 3 fixedly installed at the center of the upper front edge of the tooling frame 1, a T-shaped guide plate 4 fixedly installed at the upper end of the front upright 3, and the rear end of the T-shaped guide plate 4 fixed to the rear upright 2. The T-shaped guide plate 4 serves to allow the lateral positioning slots 6 to slide. The outer surface of the T-shaped guide plate 4 and the upper end of the rear upright 2 are both provided with lateral positioning slots 6. The lateral positioning slots 6 serve to position the four cross frames of the launcher 31. There is one lateral positioning slot 6 on the rear upright 2 and it is fixedly connected to the rear upright 2. There are three lateral positioning slots 6 on the T-shaped guide plate 4 and they are slidably connected to the T-shaped guide plate 4. This facilitates subsequent compaction operations. The spacing between the four lateral positioning slots 6 is adapted to the spacing between the four cross frames of the launcher 31, ensuring that the spacing between the four cross frames after positioning meets the processing requirements of the launcher 31.

[0034] A support bracket 8 is provided on the side of the rear support frame 2. The lower end of the support bracket 8 is fixed to the tooling frame 1. Three positioning brackets 7 are linearly arrayed and fixed on the upper end of the support bracket 8. The support bracket 8 serves to support the positioning brackets 7. The distribution of the positioning grooves on the three positioning brackets 7 is adapted to the distribution of multiple reinforcing frames 33 on the launcher 31. This ensures that after the positioning brackets 7 position the reinforcing frames 33, the distribution of the reinforcing frames 33 meets the processing requirements of the launcher 31. Two connecting frames 25 extend symmetrically from the side of the support bracket 8. The ends of the connecting frames 25 are fixed to the concave carrier frame 19. The connecting frames 25 serve to fix the concave carrier frame 19.

[0035] Two longitudinal positioning slots 10 are provided on the upper part of the tooling frame 1. The distance between the two longitudinal positioning slots 10 is adapted to the distance between the two vertical frames of the launcher 31. After the vertical frames are positioned by the longitudinal positioning slots 10, the distance between the two vertical frames meets the processing requirements of the launcher 31. The concave carrier 19, the positioning support 7, and the transverse positioning slot 6 are located between the two longitudinal positioning slots 10. The two ends of the concave carrier 19 are symmetrical with the center line of the longitudinal positioning slots 10 as the center. This ensures that after the lugs 32 are positioned at the two ends of the concave carrier 19, the position of the lugs 32 on the vertical frame of the launcher 31 meets the processing requirements of the launcher 31, thus facilitating subsequent assembly with the hydraulic cylinder 34. The lower end of one longitudinal positioning slot 10 is fixed to the tooling frame 1, and the other longitudinal positioning slot 10 is slidably connected to the concave carrier 19, which facilitates subsequent jacking operation. A jacking component is provided on the front upright 3.

[0036] Two T-shaped sliders 16 extend symmetrically from the lower end of another longitudinal positioning bracket 10. T-shaped grooves 15 are slidably mounted on the outer surface of the T-shaped sliders 16. The ends of the T-shaped grooves 15 are fixed to the concave frame 19. The cooperation between the T-shaped sliders 16 and the T-shaped grooves 15 can guide the other longitudinal positioning bracket 10.

[0037] The top support includes a threaded rod 5 that is rotatably mounted on the upper side of the front upright 3. A threaded sleeve 11 is screwed onto the outer surface of the threaded rod 5. The threaded rod 5 drives the threaded sleeve 11 to move. A top support frame 9 extends from the upper end of the threaded sleeve 11. The end of the top support frame 9 is fixed to the lower end of another longitudinal positioning slot 10. The top support frame 9 drives the longitudinal positioning slot 10 to move. A reinforcing frame 30 is rotatably mounted on the end of the threaded rod 5. The end of the reinforcing frame 30 is fixed to the front upright 3. The reinforcing frame 30 strengthens the connection of the threaded rod 5. Rotating the threaded rod 5 can drive the threaded sleeve 11 to move, which in turn drives the top support frame 9 to move, thereby pushing the longitudinal positioning slot 10 toward another longitudinal positioning slot 10. This causes the vertical frame of the launcher 31 to push against the horizontal frame, making the two fit tightly together, and also making the vertical frame of the launcher 31 and the lug 32 fit tightly together.

[0038] The front end of the top support frame 9 extends to a protruding frame 12, and the end of the protruding frame 12 is rotatably mounted with a top support connecting rod 13. The protruding frame 12 serves to connect the top support connecting rod 13. The lower side of the transverse positioning slot 6 located at the front edge of the T-shaped guide plate 4 extends to a connecting ear 14. The end of the top support connecting rod 13 is rotatably connected to the end of the connecting ear 14. The connecting ear 14 serves to facilitate the connection between the top support connecting rod 13 and the transverse positioning slot 6 at the front edge. The moving top support frame 9 will also drive the top support connecting rod 13 to move, thereby pushing the foremost transverse positioning slot 6, and then driving the foremost cross frame to move backward, so as to push the cross frame and the reinforcing frame 33, so that the cross frame and the reinforcing frame 33 of the launcher 31 fit tightly together, thereby ensuring that the various parts of the launcher 31 fit tightly together after positioning, so as to ensure the welding quality.

[0039] During welding, the two vertical frames of the launcher 31 are positioned in the two longitudinal positioning slots 10, the four horizontal frames of the launcher 31 are positioned in the four transverse positioning slots 6, and the multiple reinforcing frames 33 of the launcher 31 are positioned in the positioning slots on the three positioning supports 7. Two lugs 32 are placed at the front and rear of one end of the concave carrier 19. At this time, two positioning claws 18 engage with the upper and lower ends of the lugs 32, and the fixing magnets 17 attract and fix the lugs 32, aligning the mounting holes on the two lugs 32. Similarly, the other set of two lugs 32 are placed at the front and rear of the other end of the concave carrier 19 for fixing, thus completing the positioning of the two sets of lugs 32. Then, the threaded rod 5 is rotated to move the threaded sleeve 11, which in turn moves the top support 9, pushing the longitudinal positioning slot 10 towards another longitudinal positioning slot 10. This causes the vertical frames of the launcher 31 to push against the horizontal frames, making... The two fit together tightly, allowing the vertical frame and lug 32 of the launcher 31 to fit together tightly. At the same time, the moving top support frame 9 will also drive the top support connecting rod 13 to move, pushing the frontmost horizontal positioning slot 6, which in turn drives the frontmost horizontal frame to move backward, pushing the horizontal frame and reinforcing frame 33 together, so that the horizontal frame and reinforcing frame 33 of the launcher 31 fit together tightly. This ensures that the various parts of the launcher 31 fit together tightly after positioning. Then, the various parts of the launcher 31 can be welded together to assemble the launcher 31. After welding, the threaded column 26 is rotated to drive the slot joint 29 on the moving frame 27 to move down, which in turn drives the release claw frame 22 to move, pulling the double-headed frame 23, so that the connecting claw seat 24 can rotate around the connecting rod 20, thereby lifting the upper positioning claw 18 to disengage it from the lug 32, so that the welded launcher 31 can be lifted and removed smoothly, which facilitates the unloading after welding.
