Description

Technical Field

[0001] This utility model belongs to the field of shot peening technology, specifically relating to a shot peening device for the rounded corners of a ribbed wall panel. Background Technology

[0002] Currently, in aerospace and other fields, in order to improve the overall strength and reliability of stiffened panels, integral processing or welding processes are generally used to complete the manufacturing of parts. Therefore, the local welding positions of the parts, especially the rounded corner areas where stiffeners connect to the panels, need to be treated with shot peening. This is mainly to remove stress from processing and welding, and ultimately improve the strength and reliability of the stiffened panels.

[0003] Existing shot blasting is carried out in a shot blasting room. After shot blasting in the room, the wall panels need to be transferred, and the un-shot-blasted areas on the wall panels need to be protected. The entire shot blasting process is time-consuming and labor-intensive, and the effect after shot blasting cannot be observed in real time. Moreover, the overall shape of the wall panels varies, and the size is also different, ranging from 1 meter to 19 meters in length and from 0.5 meters to 3 meters in width. If the overall size of the reinforced wall panels is too large, a temporary shot blasting room needs to be built. Furthermore, if steel shot needs to be replaced, it will consume a lot of manpower and material resources. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shot peening device for the rounded corners of a ribbed wall panel, which can perform shot peening in an open space, is easy to operate, and will not damage the areas that do not need shot peening.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a shot peening device for the rounded corners of a ribbed wall panel, comprising a shell, a shot peening gun, and wheels. Rib through holes adapted to the ribs of the ribbed wall panel are provided at the front and rear ends of the shell. The wheels are arranged on both sides of the shell along the direction of the ribs. A shot peening gun is fixedly installed on one or both sides of the shell. A sealed shot peening chamber is formed between the interior of the shell and the wall panel of the ribbed wall panel.

[0006] Preferably, the outer shell can be separately configured along the through holes of the reinforcing ribs.

[0007] Preferably, a limiting wheel that rolls along the side of the stiffener is provided inside the outer shell.

[0008] Preferably, the housing includes a side plate and an end cap, with the two end caps fixedly and sealed at both ends of the side plate, a side plate seal between the side plate and the wall plate, and an end cap seal between the end cap and the wall plate.

[0009] Preferably, a cover plate is fixedly provided between the end cap and the side plate, and a cover plate sealing gasket is fixedly provided between the cover plate and the side plate.

[0010] Preferably, an end sealing gasket is also fixedly provided at the lower end of the end cap. The end sealing gasket is made of rubber. The end cap sealing element is fixedly provided on one side of the end sealing gasket, and rib through holes are provided on both the end cap sealing element and the end sealing gasket.

[0011] Preferably, both the side plate seal and the end cap seal are sealing strips.

[0012] Preferably, an adjusting bolt and a spring are provided on the upper side of the side plate seal. The adjusting bolt is threaded onto the side plate, and the spring is located below the adjusting bolt. The lower end of the spring presses against the side plate seal.

[0013] Preferably, a shot recovery device is provided on one side of the shot peening gun.

[0014] Preferably, when a shot peening gun is fixedly installed only on one side of the housing, a rib seal is fixedly provided on the inner side of the top of the housing along the travel direction, and the rib seal is pressed against the upper side of the rib.

[0015] Preferably, a rubber protective layer is fixedly provided inside the outer shell corresponding to the shot peening gun to extend the service life of the outer shell.

[0016] Compared with existing technologies, the above technical solution has the following beneficial effects:

[0017] 1. This utility model has a shot peening gun fixedly installed on one or both sides of the outer shell, forming a sealed shot peening chamber inside the outer shell. One end of the device is stuck on the outside of the rib plate of the ribbed wall panel, and the device is pushed to move along the rib plate. The shot peening gun peens shot at the rounded corner where the rib plate and the wall panel connect. This device can be used for shot peening in an open space. It is simple to operate, does not require moving the wall panel, and does not need to be carried out in a shot peening room, which greatly saves manpower and material resources.

[0018] 2. This device adopts two sealing structures at the end cap: a sealing strip is sandwiched between the end sealing gasket and the cover plate sealing gasket to ensure the sealing of the device. The end cap sealing component uses a sealing strip. The brush structure has low frictional resistance when moving, making it easy to operate.

[0019] 3. A limiting wheel is installed inside the outer shell. The limiting wheel moves along the rib plate to ensure that the position of the shot peening gun and the shot peening remains unchanged, thus ensuring the quality of shot peening.

[0020] 4. A top sealing strip is installed on the outer shell to divide the shot blasting space into two independent spaces that do not affect each other. This reduces the area of ​​the shot blasting space and makes it easier to recover steel shot, reducing the risk of shot spillage.

[0021] 5. The outer shell consists of two separate parts, which can be opened to place the shot peening material at any position, avoiding the need to enter only from the end, thus greatly improving efficiency.

[0022] 6. Adjusting bolts and springs are installed on the upper side of the side plate seal. The tightness of the bolts is adjusted according to the shape of the contact surface to adapt to different cross sections. If the contact surface has a slope or is uneven, the tightness of the bolts is adjusted to adjust the force of the brush strip contacting the plane, which can achieve the sealing effect while adjusting the magnitude of friction and the pushing force to achieve the effect of saving effort and sealing.

[0029] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0030] like Figure 1As shown, a shot peening device for the rounded corner of a ribbed wall panel according to this utility model includes a housing, a shot peening gun 1, and traveling wheels 5. The traveling wheels 5 are arranged on both sides of the housing. The shot peening gun 1 is fixedly installed on one or both sides of the housing. The nozzle 3 of the shot peening gun 1 is fixedly installed on the housing. Rib through holes 11 are provided at the front and rear ends of the housing corresponding to the ribs 28. In this embodiment, a ribbed wall panel with "T"-shaped ribs 28 is taken as an example. The rounded corner 29 where the ribs 28 and the wall panel 27 are connected needs to be shot peened. The rib through holes 11 are set to "T" shape to form a sealed shot peening chamber 26 inside the housing. The shot peening gun 1 passes through the rib through holes 11 at the front and rear ends of the housing from one end of the rib 28 and peens shot peening the rounded corner 29.

[0031] like Figure 2 As shown, the outer casing includes side plates and end caps 12. Two end caps 12 are fixedly and sealed at both ends of the side plates. A cover plate 13 is fixedly disposed between the end caps 12 and the side plates, and a cover plate sealing gasket 14 is fixedly disposed between the cover plate 13 and the side plates to ensure a sealed connection between the end caps 12 and the side plates. A side plate seal is disposed between the side plates and the wall plate 27, and an end cap seal is disposed between the end caps 12 and the wall plate 27 to ensure a seal between the side plates, end caps 12, and wall plate 27, providing a sealed shot peening chamber 26. The outer casing adopts an arched structure, spanning across the stiffening rib 28. The two sides of the outer casing are machined according to the shot peening angle, inclined at 40°~55° relative to the plane to ensure the optimal shot peening angle.

[0032] like Figure 3 As shown, in this embodiment, the end cap seal is an end sealing strip 9. An end sealing gasket 10 is also fixedly installed at the lower end of the end cap 12. The end sealing gasket 10 is made of rubber. The end sealing strip 9 is fixedly installed on one side of the end sealing gasket 10. Rib through holes 11 are provided on both the end sealing strip 9 and the end sealing gasket 10 for the rib plate 28 to pass through. The end sealing strip 9 adopts a nylon bristle brush structure with a thickness of 8~10mm. It can not only play a sealing role, but also has low frictional resistance when moving, which facilitates the movement of this device. The end sealing strip 9 is sandwiched between the end sealing gasket 10 and the cover plate sealing gasket 14 on the end cap 12, which provides double sealing, which can not only meet the sealing requirements, but also reduce the friction when the device moves.

[0033] In this embodiment, the outer shell is divided into a left outer shell and a right outer shell, with the side plates and end caps 12 being separately configured. The end caps 12 are also divided into a left end cap and a right end cap, and the side plates are divided into a left side plate 6 and a right side plate 7. The end caps 12 are fixedly connected to their respective side plates, and the left side plate 6 and the right side plate 7 are separated at the through hole 11 in the stiffener plate. Connecting holes 15 are provided on the left side plate 6 and the right side plate 7, and the left side plate 6 and the right side plate 7 are fixedly connected by connecting bolts 16. If the side plates are integrated, the device can only enter from the end of the stiffener plate 28 to start shot peening. By dividing the outer shell into two parts, for the longer wall plate 27, the right side plate 7 can be opened and shot peening can be performed at any position, which greatly improves the efficiency.

[0034] like Figures 4-5 As shown, side plate seals are fixedly installed on the lower sides of both the left side plate 6 and the right side plate 7. In this embodiment, the side plate seal is also a side sealing strip 8, which also adopts a nylon bristle brush structure with a thickness of 8-10mm. An adjusting bolt 18 and a spring 17 are provided on the upper side of the side sealing strip 8. An adjusting threaded hole 19 is machined on the side plate, and a fixing hole 20 for accommodating the spring 17 is opened on the lower side of the adjusting threaded hole 19. The adjusting bolt 18 is threadedly connected to the outer shell, and the upper end of the spring 17 is located below the adjusting bolt 18. Alternatively, a pressure pad can be provided above the spring 17, and the adjusting bolt 18 presses down on the pressure pad. A spring 17 is tightened, with its lower end pressing against the side sealing strip 8. A mounting groove 21 is provided on the lower side of the side plate, and the upper end of the side sealing strip 8 is installed within the mounting groove 21. A fixing plate 22 is fixedly installed on the upper end of the side sealing strip 8, and the spring 17 is pressed against the fixing plate 22. The tightness of the adjusting bolt 18 is adjusted according to the shape of the contact surface of the wall panel 27 to adapt to different cross-sections. If the contact surface has a slope or is uneven, adjusting the tightness of the adjusting bolt 18 adjusts the force on the contact surface of the side sealing strip 8, achieving both a sealing effect and adjusting the magnitude of friction and the pushing force, thus achieving a labor-saving and sealing effect. Similarly, the end sealing strip 9 at the lower end of the end cap 12 can also be made adjustable.

[0035] In this embodiment, the shot peening gun 1 is fixedly installed on only one side of the outer shell, and a rib seal is fixedly installed on the top inside the outer shell. The rib seal is a top sealing strip 25. The top sealing strip 25 is pressed against the upper side of the rib 28. The top sealing strip 25 divides the shot peening space into two independent spaces that do not affect each other, thus reducing the area of ​​the shot peening space. A rubber protective layer 30 is fixedly installed inside the outer shell corresponding to the shot peening gun 1 to extend the service life of the outer shell.

[0036] A shot blasting gun 1 is equipped with a shot recovery device on one side. The shot recovery device is fixedly connected to the outer casing via a vacuum recovery tube 2. A top sealing strip 25 divides the shot blasting space into two independent spaces, which is more conducive to the recovery of shot and reduces the risk of shot spillage. The shot blasting gun 1 is tilted at 15°~20° towards the shot recovery device, so that the shot is quickly recovered after rebound, reducing the probability of repeated impact. The shot blasting gun 1 adopts a Venturi structure, which precisely controls the shot blasting area by controlling the diameter of the nozzle and the distance between the nozzle and the spray point. The outer casing has shot blasting installation holes and shot recovery installation holes. Each hole is equipped with a positioning screw, which can fix the shot blasting gun 1 and adjust the positional relationship between the shot blasting gun 1 and the outer casing to achieve the ideal state of shot blasting and recovery.

[0037] A limiting wheel 24 is installed inside the outer casing. The limiting wheel 24 is rotatably mounted inside the outer casing via a connecting shaft 23 and rolls along the side of the rib plate 28. The limiting wheel 24 moves along the rib plate 28 without deviating, ensuring that the position of the shot peening gun 1 and the shot peening remains unchanged, thus ensuring the shot peening quality. The limiting wheel 24 adopts a plastic-coated structure to avoid damaging the rib plate 28. In this embodiment, two limiting wheels 24 are arranged at intervals along the length direction inside the outer casing. Two traveling wheels 5 are provided on each side of the outer casing, which can control the vertical height and ensure that the position of the shot peening gun 1 will not change even if the downward pressure device is applied too forcefully. The traveling wheels 5 adopt a plastic-coated traveling wheel to avoid damaging the wall plate 27. A handle 4 is fixedly installed on the upper side of the outer casing. A start button can be installed on the handle 4 to control the shot peening gun 1, which can be operated by one person or connected to automated shot peening equipment without having to travel a long distance to start the equipment.

[0038] When using this utility model, the device is moved onto the wall panel 27. If shot peening needs to start from the end of the rib plate 28, the rib plate 28 is inserted into the rib plate through hole 11 on the end cap 12 at the front end of the device. The shot peening gun 1 is started, and the shot peening gun 1 peens shot at the rounded corner 29. At the same time, the steel shot recovery device recovers the steel shot synchronously. The device is pushed along the rib plate 28 by the handle 4 until the shot peening of the lower rounded corner 29 of the rib plate 28 is completed. This device can perform shot peening operations in open spaces. The operation is simple and does not require moving the wall panel 27, which greatly saves manpower and material resources.

[0039] In other embodiments, the shot peening device at the rounded corner of the ribbed wall panel can also move automatically along the ribbed wall panel under the drive of automated equipment, or the shot peening device can be fixedly installed and move automatically past the shot peening device under the drive of automated equipment to complete the shot peening process of the rounded corner area.
