Description

Technical Field

[0001] This invention belongs to the field of welding technology, specifically a nozzle housing connection and positioning fixture. Background Technology

[0002] The nozzle casing is a key structural component in systems such as rocket engines, jet engines, and fire extinguishing devices. Its main functions are to house the high-temperature, high-pressure gas flow channels, withstand aerodynamic loads, and connect other components. During the manufacturing process of the nozzle casing, a large number of studs are often spot-welded onto the inner thin plate, passing through positioning holes on the outer layer to precisely position the tiny cooling channel gap between the two plates, preventing the outer plate from collapsing inward under high temperatures. To facilitate welding, the studs need to be pre-fixed to the plate before welding.

[0003] In existing technologies, when welding studs to sheet metal, workers typically manually place the stud head against the sheet surface and then weld along the joint using a welding torch. When there are many studs, this method is labor-intensive and prone to misalignment due to operational errors, affecting welding accuracy. Even with the introduction of robotic arms to replace manual placement, if the studs are randomly stacked and haphazardly positioned during the feeding process, the vision system struggles to reliably distinguish the stud heads and tails and graspable features in unstructured material piles. This can easily lead to misgrabbing or reverse installation due to obstruction and confusion, directly causing welding failure.

[0004] Furthermore, when welding studs of various specifications is required, the visual template needs to be manually adjusted each time the model is changed. This inflexible "one-size-fits-one" approach is difficult to adapt to different welding requirements of the nozzle shell, resulting in a significant loss of the advantages of automation efficiency. Summary of the Invention

[0008] The material handling assembly includes multiple rotatable clamping blocks that can move along the x, y, and z axes.

[0010] The plate positioning assembly includes two cylinders symmetrically arranged on the welding table, and a positioning block is fixedly connected to the piston end of each cylinder.

[0011] Preferably, the vibration generating structure includes a flip plate, on which multiple spring dampers are fixedly mounted, and the piston ends of the multiple spring dampers are fixedly connected to the discharge frame. An electromagnetic vibrator is mounted on the discharge frame.

[0012] Preferably, a support column is fixedly provided on the welding table, and a motor is fixedly provided on the support column. The output end of the motor is fixedly connected to the rotating end of the flip plate.

[0013] Preferably, a connecting frame is provided on the upper side of the discharge frame, and multiple telescopic plates are fixedly connected to the connecting frame.

[0015] Preferably, a second cylinder is fixedly mounted on the transverse plate, and the equidistant variable pitch slide is fixedly mounted on the piston end of the second cylinder.

[0016] Preferably, the crossbeam is equipped with a downward-pull-down anti-disengagement component;

[0017] The downward-pull-out anti-disengagement component includes a support plate fixedly connected to both ends of the crossbeam. A sprocket is rotatably mounted on the support plate, and a chain is meshed on the sprocket. Multiple downward-pull strips made of elastic material are mounted on the chain.

[0018] Preferably, a worm gear is fixedly sleeved on the rotating end of the sprocket, a worm is rotatably mounted on the support plate, the worm has multiple helical teeth, and each helical tooth meshes with a worm gear, and a second motor is fixedly mounted on the support plate, the output end of the second motor being fixedly connected to one end of the worm.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The nozzle housing connection and positioning fixture of the present invention, with the coordinated cooperation of the multi-channel interception material handling component and the material handling component, utilizes the structural feature that the diameter of the stud head is larger than that of the main body, and combines the adjustable width strip channel with vibration material handling, so that the scattered and disordered studs can automatically complete the attitude correction and form an orderly arrangement in the channel, completely eliminating the visual recognition difficulties and the hidden dangers of mis-grabbing and reverse installation caused by the unstructured material pile, and ensuring the welding accuracy from the source.

[0021] Furthermore, through the cooperation of the equidistant variable-pitch slide and clamping blocks, multiple neatly arranged studs can be accurately picked up and flipped at once. The stud spacing can also be flexibly adjusted according to the welding position, achieving multi-point synchronous positioning, significantly reducing worker labor intensity and greatly improving work efficiency. Moreover, the width of the strip channel can be quickly adjusted simply by controlling the telescopic plate, easily adapting to the body and head dimensions of studs of different specifications. This eliminates the need for traditional visual template adjustment steps, giving the system a flexible production capability for rapid changeover, perfectly meeting the different welding requirements of the nozzle shell.

[0022] 2. The nozzle housing connection and positioning fixture of the present invention utilizes a downward-pull-type anti-detachment component. During the vibration of the discharge frame, multiple downward-pulling bars also move. When the downward-pulling bars descend, they contact the studs in the strip channel. Since the downward-pulling bars are made of elastic material, they provide a continuous and flexible downward pushing force to the studs that have passed through the strip channel. This pushing force can actively and continuously drag the studs located in the strip channel downward, thereby effectively counteracting the interference force caused by the vibration of the discharge frame and the impact of the studs above, preventing the studs that have been positioned from detaching from the strip channel, ensuring a stable and orderly material handling process, and providing a reliable guarantee for subsequent material handling.

[0037] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please refer to Figures 1-12The present invention provides a technical solution: a nozzle housing connection and positioning fixture, including a machine cover 31, a welding table 1 inside the machine cover 31, and a multi-channel interception material handling component and a material picking component for placing studs on the plate.

[0039] The multi-channel interception feeding assembly includes a discharge frame 5 and a vibration generating structure that causes the discharge frame 5 to vibrate. Multiple crossbeams 16 are arranged and fixedly connected at equal intervals along the bottom of the discharge frame 5. Telescopic plates 19 are slidably inserted into the grooves of the crossbeams 16. The multiple telescopic plates 19 and the multiple crossbeams 16 cooperate with each other to form a strip channel with a width greater than the diameter of the stud body and smaller than the diameter of the stud head.

[0040] The material handling assembly includes multiple rotatable clamping blocks 29 that can move along the x, y, and z axes. The clamping blocks 29 clamp the studs arranged in the strip channel and remove the studs from the strip channel. Finally, the studs are placed on the surface of the plate and welded by the welding equipment.

[0041] In this embodiment, as Figures 2-6 , Figures 9-12 As shown, the welding table 1 is equipped with a plate positioning assembly;

[0042] The plate positioning assembly includes two cylinders 2 symmetrically arranged on the welding table 1, and a positioning block 3 is fixedly connected to the piston end of the cylinder 2.

[0043] The vibration generating structure includes a tilting plate 10, on which multiple spring dampers 8 are fixedly mounted. The piston ends of the multiple spring dampers 8 are fixedly connected to the discharge frame 5, and the discharge frame 5 is equipped with an electromagnetic vibrator 7.

[0044] A support column 30 is fixedly installed on the welding table 1, and a motor 9 is fixedly installed on the support column 30. The output end of the motor 9 is fixedly connected to the rotating end of the flip plate 10.

[0045] A connecting frame 17 is provided on the upper edge of the discharge frame 5, and multiple telescopic plates 19 are fixedly connected to the connecting frame 17. A cylinder 3 18 is fixedly provided on the discharge frame 5, and the piston end of the cylinder 3 18 is fixedly connected to one end of the connecting frame 17.

[0046] The welding table 1 is equipped with a lead screw slide rail module 1 4, which is equipped with a movable transverse frame 6. The transverse frame 6 is equipped with a lead screw slide rail module 2 12, which is equipped with a transverse plate 13 that can move laterally. Two guide rods 15 slide vertically through the transverse plate 13. The bottom of the two guide rods 15 are fixedly connected to an equidistant variable pitch slide 26. The equidistant variable pitch slide 26 is equipped with multiple sliders 27 whose spacing can be changed. Positioning arms 28 slide on the sliders 27. Each clamping block 29 is rotatably mounted on a positioning arm 28. The sliders 27 are equipped with a displacement drive device for driving the two positioning arms 28 to move towards or away from each other. The positioning arms 28 are equipped with a rotation drive device for driving the clamping blocks 29 to rotate.

[0047] A second cylinder 14 is fixedly mounted on the transverse plate 13, and an equidistant variable pitch slide 26 is fixedly mounted on the piston end of the second cylinder 14.

[0048] Specifically, in existing technologies, when welding studs to sheet metal, workers typically manually place the stud head against the sheet surface and then weld along the joint using a welding torch. When there are many studs, this method is labor-intensive and prone to misalignment due to operational errors, affecting welding accuracy. Even if a robotic arm is introduced to replace manual placement, if the studs are randomly stacked and in random positions during the feeding process, the vision system will have difficulty reliably distinguishing the head and tail of the studs and their graspable features in unstructured material piles. This can easily lead to misgrabbing or reverse installation due to obstruction and confusion, directly causing welding failure.

[0049] Furthermore, when welding studs of various specifications is required, the visual template needs to be manually adjusted each time the model is changed. This inflexible "one-size-fits-one" approach is difficult to adapt to different welding requirements of the nozzle shell, resulting in a significant loss of the advantages of automation efficiency.

[0050] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0051] This embodiment is applied to fix studs of the same specification to a sheet metal in a single application. First, the sheet metal is placed between two positioning blocks 3. The positioning blocks 3 are moved by cylinder 2, and the two positioning blocks 3 cooperate to clamp the sheet metal.

[0052] Since the head diameter of the stud is larger than the body diameter, this structural feature can be used to drive the connecting frame 17 to move laterally on the discharge frame 5 via cylinder 3 18. Then, multiple telescopic plates 19 can slide in the grooves of multiple crossbeams 16 respectively. By controlling the extension area of ​​the telescopic plates 19, the width of the strip channel can be adjusted so that the width is greater than the body diameter of the stud and less than the head diameter of the stud.

[0053] After the above adjustment work is completed, place the multiple studs to be welded in the discharge frame 5, and then turn on the electromagnetic vibrator 7. The electromagnetic vibrator 7 and the spring damper 8 work together to make the discharge frame 5 vibrate. The multiple studs in the discharge frame 5 will continuously adjust their posture under the action of vibration until the main body of the stud passes through the strip channel. Since the diameter of the stud head is larger than the width of the strip channel, the stud head will get stuck in the strip channel.

[0054] After all the studs have passed through the strip channel under the continuous vibration of the discharge frame 5, the motor 9 drives the tilting plate 10 to rotate, causing the discharge frame 5 to tilt at a certain angle. The studs will then slide along the strip channel under gravity, allowing multiple studs to fit together in the strip channel. At this point, the distance between the axial centers of two adjacent studs in the strip channel is the same as the diameter of the stud head.

[0055] Subsequently, the equidistant variable pitch slide 26 is moved by the lead screw slide module 14, the lead screw slide module 22, and the cylinder 24, thereby adjusting its position in the x, y, and z axis directions, so that multiple clamping blocks 29 extend into the discharge frame 5. Then, according to the distance between the centers of two adjacent studs, the equidistant variable pitch slide 26 drives multiple sliders 27 to slide simultaneously, so that the distance between adjacent sliders 27 changes and matches the distance between the centers of adjacent studs. The equidistant variable pitch slide 26 is existing technology and will not be described in detail here.

[0056] Multiple clamping blocks 29 can simultaneously align with multiple studs in the strip channel. Then, a displacement drive device drives the two positioning arms 28 on the slider 27 to move closer together, clamping the stud heads with the clamping blocks 29. The studs are then moved from the discharge frame 5 and positioned above the plate. Next, a rotation drive device on the positioning arm 28 drives the clamping blocks 29 to rotate the studs 180 degrees, so the stud heads face downwards. The spacing between adjacent studs is then adjusted according to actual welding requirements, and the studs are placed on the plate. The clamping blocks 29 then release the studs, move upwards, and finally press the studs together by contacting the top of the studs, thus achieving stud positioning. At this point, the studs can be welded to the plate manually with a handheld welding torch or using automatic welding equipment.

[0057] Repeat the above operation until all the studs in the discharge frame 5 are removed and welded onto the plate. With the coordinated operation of the multi-channel interception material handling component and the material handling component, and by utilizing the structural feature that the stud head diameter is larger than the body, the studs are automatically corrected in posture and arranged in an orderly manner through the adjustable width strip channel combined with vibration material handling. This completely eliminates the visual recognition difficulties and the hidden dangers of mis-grabbing and reverse installation caused by the unstructured material pile, and ensures welding accuracy from the source.

[0058] Furthermore, through the cooperation of the equidistant variable-pitch slide 26 and the clamping block 29, multiple neatly arranged studs can be accurately picked up and flipped at once. The stud spacing can also be flexibly adjusted according to the welding position, achieving multi-point synchronous positioning, significantly reducing worker labor intensity and greatly improving work efficiency. Moreover, the width of the strip channel can be quickly adjusted simply by controlling the telescopic plate 19, easily adapting to the body and head dimensions of studs of different specifications. This eliminates the need for traditional visual template adjustment steps, giving the system a flexible production capability for rapid changeover, perfectly meeting the different welding requirements of the nozzle shell.

[0059] In this embodiment, as Figures 6-8 As shown, the crossbeam 16 is equipped with a downward-pull-down anti-detachment component;

[0060] The downward-pull-out anti-disengagement component includes a support plate 11 fixedly connected to both ends of the crossbeam 16. A sprocket 25 is rotatably mounted on the support plate 11. A chain 24 is meshed on the sprocket 25. Multiple downward-pull strips 23 made of elastic material are mounted on the chain 24.

[0061] A worm gear 22 is fixedly sleeved on the rotating end of the sprocket 25. A worm 21 is rotatably mounted on the support plate 11. The worm 21 has multiple helical teeth, and each helical tooth meshes with a worm gear 22. A second motor 20 is fixedly mounted on the support plate 11. The output end of the second motor 20 is fixedly connected to one end of the worm 21.

[0062] Specifically, in the above embodiments, although the posture of the studs can be continuously adjusted by vibration until all studs pass through the strip channel, the studs will still be vibrated after passing through the strip channel, causing the studs that have passed through the strip channel to fall out again. Furthermore, the studs that have not passed through the strip channel will also collide with the studs that have fallen into the strip channel due to vibration. The studs that are collided are also prone to being moved out of the strip through hole. Under this continuous cycle, the material handling will fail, which will affect the normal progress of subsequent welding work.

[0063] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0064] During the vibration of the discharge frame 5, the motor 20 drives the worm gear 21 to rotate, which in turn causes multiple sprockets 25 to rotate simultaneously under the transmission cooperation of the worm gear 21 and the worm wheel 22. The sprockets 25 drive the chain 24 to rotate, and multiple lower guide bars 23 also move along with it. When the lower guide bars 23 descend, they will contact the studs in the strip channel. Since the lower guide bars 23 are made of elastic material, they will provide a continuous and flexible downward push for the studs that have passed through the strip channel. Through this push, the studs located in the strip channel can be actively and continuously dragged downward, thereby effectively counteracting the interference force caused by the vibration of the discharge frame 5 and the impact of the studs above, preventing the studs that have been placed from falling out of the strip channel, ensuring the stable and orderly material handling process, and providing a reliable guarantee for subsequent material handling.

[0065] Working principle: First, the board is placed between two positioning blocks 3. The positioning blocks 3 are moved by cylinder 2, and the two positioning blocks 3 cooperate to clamp the board.

[0066] Since the head diameter of the stud is larger than the body diameter, this structural feature can be used to drive the connecting frame 17 to move laterally on the discharge frame 5 via cylinder 3 18. Then, multiple telescopic plates 19 can slide in the grooves of multiple crossbeams 16 respectively. By controlling the extension area of ​​the telescopic plates 19, the width of the strip channel can be adjusted so that the width is greater than the body diameter of the stud and less than the head diameter of the stud.

[0067] After the above adjustment work is completed, place the multiple studs to be welded in the discharge frame 5, and then turn on the electromagnetic vibrator 7. The electromagnetic vibrator 7 and the spring damper 8 work together to make the discharge frame 5 vibrate. The multiple studs in the discharge frame 5 will continuously adjust their posture under the action of vibration until the main body of the stud passes through the strip channel. Since the diameter of the stud head is larger than the width of the strip channel, the stud head will be stuck at the strip through hole.

[0068] After all the studs have passed through the strip channel under the continuous vibration of the discharge frame 5, the motor 9 drives the tilting plate 10 to rotate, causing the discharge frame 5 to tilt at a certain angle. The studs will then slide along the strip channel under gravity, allowing multiple studs to fit together in the strip channel. At this point, the distance between the axial centers of two adjacent studs in the strip channel is the same as the diameter of the stud head.

[0069] Subsequently, the equidistant variable pitch slide 26 is moved by the lead screw slide module 14, the lead screw slide module 22, and the cylinder 24, thereby adjusting its position in the x, y, and z axis directions, so that multiple clamping blocks 29 extend into the discharge frame 5. Then, according to the distance between the centers of two adjacent studs, the equidistant variable pitch slide 26 drives multiple sliders 27 to slide simultaneously, so that the distance between adjacent sliders 27 changes and matches the distance between the centers of adjacent studs. The equidistant variable pitch slide 26 is existing technology and will not be described in detail here.

[0070] Multiple clamping blocks 29 can simultaneously align with multiple studs in the strip channel. Then, a displacement drive device drives the two positioning arms 28 on the slider 27 to move closer together, clamping the stud heads with the clamping blocks 29. The studs are then moved from the discharge frame 5 and positioned above the plate. Next, a rotation drive device on the positioning arm 28 drives the clamping blocks 29 to rotate the studs 180 degrees, so the stud heads face downwards. The spacing between adjacent studs is then adjusted according to actual welding requirements, and the studs are placed on the plate. The clamping blocks 29 then release the studs, move upwards, and finally press the studs together by contacting the top of the studs, thus achieving stud positioning. At this point, the studs can be welded to the plate manually with a handheld welding torch or using automatic welding equipment.

[0071] Repeat the above operation until all the studs in the discharge frame 5 are removed and welded onto the plate. With the coordinated operation of the multi-channel interception material handling component and the material handling component, and by utilizing the structural feature that the stud head diameter is larger than the body, the studs are automatically corrected in posture and arranged in an orderly manner through the adjustable width strip channel combined with vibration material handling. This completely eliminates the visual recognition difficulties and the hidden dangers of mis-grabbing and reverse installation caused by the unstructured material pile, and ensures welding accuracy from the source.

[0072] Furthermore, through the cooperation of the equidistant variable-pitch slide 26 and the clamping block 29, multiple neatly arranged studs can be accurately picked up and flipped at once. The stud spacing can also be flexibly adjusted according to the welding position, achieving multi-point synchronous positioning, significantly reducing worker labor intensity and greatly improving work efficiency. Moreover, the width of the strip channel can be quickly adjusted simply by controlling the telescopic plate 19, easily adapting to the body and head dimensions of studs of different specifications. This eliminates the need for traditional visual template adjustment steps, giving the system a flexible production capability for rapid changeover, perfectly meeting the different welding requirements of the nozzle shell.
