Description

Technical Field

[0001] This application relates to the field of defect repair technology for aluminum alloy sealing parts, and in particular to a localized patching device for silicon-aluminum alloy castings. Background Technology

[0002] A patent document with publication number CN217343567U discloses a localized patching device for aluminum alloy sealing components, including a plug, an air pipe connector, a sealing ring, and an air supply device. The plug has a stepped outer end, comprising a small stepped portion at the lower end and a large stepped portion at the upper end. The small stepped portion is a screw structure that engages with the threaded mounting hole of the aluminum alloy casting to be patched. An axially extending stepped through hole is machined in the middle of the plug, comprising a large stepped hole at the upper end and a small stepped hole connected to the lower end of the large stepped hole. The air pipe connector is installed in the large stepped hole at the upper end of the plug, and the air pipe connector is connected to the air supply device via an air pipe. After the sealing ring is fitted over the small stepped portion of the plug, the upper end face of the sealing ring abuts against the lower end face of the large stepped portion of the plug, and the lower end face of the sealing ring abuts against the upper end face of the aluminum alloy casting. This device is simple to manufacture, easy to operate, low in cost, and has high patching efficiency.

[0003] The diameters of the mounting holes processed from different castings for installation with other components are all different. In actual use, the above solutions are limited because the size of the plugs used to seal the threaded mounting holes of the castings is fixed, and they can only be used with threaded mounting holes of specific sizes. This cannot meet the needs of patching various sizes of casting mounting holes, and the applicability is limited. Therefore, this application provides a local patching device for silicon-aluminum alloy castings. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a localized patching device for silicon-aluminum alloy castings. This device overcomes the deficiencies of existing technologies and aims to solve the problem that the diameters of the mounting holes processed from different castings for installation with other components are not the same. In practical use, the above solutions are limited in scope of application because the size of the plug used to seal the threaded mounting holes of the castings is fixed, and it can only be used with threaded mounting holes of specific sizes. This makes it impossible to meet the patching needs of mounting holes of various sizes of castings.

[0005] To achieve the above objectives, this application provides the following technical solution: a localized seepage repair device for silicon-aluminum alloy castings, comprising a casting body and a top cover. The casting body is provided with several sets of mounting holes. The top cover is placed at the top of the casting body. A fixing pipe is fixedly installed in the middle of the top cover. An air supply pipe is fixedly installed inside the fixing pipe. Both ends of the air supply pipe pass through the fixing pipe. A connecting sleeve is fixedly installed on the outer surface of the fixing pipe below the top cover. An air bladder is fixedly installed on the outer ring of the connecting sleeve. An air pipe is connected to the top of the air bladder. An electric air pump is installed through the top cover at the top of the air pipe.

[0006] By adopting the above technical solution, firstly, a seepage-repairing liquid is added into the mounting hole. Then, the top cover is placed at the mounting hole and snapped onto the casting body. Next, the inflation function of the electric air pump is activated, and the electric air pump inflates the airbag through the air pipe. The airbag expands and tightly fits the inner wall of the mounting hole, forming a seal. Then, the air inlet end of the air supply pipe is connected to an external compressed air source, and high-pressure gas is injected into the mounting hole through the air supply pipe, thereby quickly and effectively repairing the leakage point. By inflating the airbag, mounting holes of different sizes can be sealed, which is beneficial to meeting the seepage-repairing needs of mounting holes of various sizes of casting bodies and improving the applicability.

[0007] As a preferred technical solution of this application, two sets of connecting rods are fixedly installed at the bottom end of the connecting sleeve, and ultraviolet lamps are fixedly installed at the bottom ends of the two sets of connecting rods.

[0008] By adopting the above technical solution, after high-pressure gas is injected into the mounting hole, the ultraviolet lamp is turned on to solidify the seepage liquid in the mounting hole. This eliminates the need to immerse the casting in hot water, which helps to improve the solidification efficiency and shorten the seepage time.

[0009] As a preferred technical solution of this application, the bottom end of the fixed tube is connected to a uniform head, and the bottom of the uniform head is provided with several sets of uniform holes.

[0010] By adopting the above technical solution, high-pressure gas is delivered to the uniform head through the gas supply pipe, and the repair fluid is evenly penetrated into the defects of the casting body through several sets of uniform holes, thereby improving the penetration and repair effect on the defects of the casting body.

[0011] As a preferred technical solution of this application, a bracket is fixedly installed on the top of the top cover, the top of the electric air pump is fixedly installed on the bracket, and a controller is fixedly installed on one side of the top of the top cover located on the bracket, and the controller is electrically connected to the electric air pump.

[0012] By adopting the above technical solution, the bracket enhances the support effect of the electric air pump, and the controller facilitates the operation of the electric air pump, thus improving its practicality during use.

[0013] As a preferred technical solution of this application, a pressure detector is installed inside the airbag, and the pressure detector is connected to the controller signal.

[0014] By adopting the above technical solution, the pressure change inside the airbag is monitored in real time by the pressure detector. When the controller receives the pressure monitoring value of the pressure detector and it reaches the preset value, the electric air pump is controlled to stop working, which helps to ensure the airbag's sealing performance.

[0015] As a preferred technical solution of this application, a pressure detector two is fixedly installed at the bottom of the air supply pipe. The pressure detector two is located between the connecting sleeve and the uniform head, and the pressure detector two is connected to the controller signal.

[0016] By adopting the above technical solution, the pressure change in the mounting hole is monitored in real time by pressure detector 2. When the controller receives the pressure monitoring value of pressure detector 2 and it reaches the preset value, the high-pressure gas filling into the mounting hole is stopped, which improves the safety during use.

[0017] As a preferred technical solution of this application, four sets of weighted blocks are fixedly installed on the top of the top cover.

[0018] By adopting the above technical solution, the weight of the top cover is increased by four sets of weighted blocks, thus ensuring the stability of the top cover.

[0019] As a preferred technical solution of this application, a quick-connect fitting is fixedly installed at the air inlet end of the air supply pipe, and a shut-off valve and a pressure reducing valve are installed inside the air supply pipe, with the shut-off valve located between the quick-connect fitting and the pressure reducing valve.

[0020] By adopting the above technical solution, after connecting the air inlet of the air supply pipe to an external compressed air source, the gas pressure entering the air supply pipe is set through the pressure reducing valve. Then, the shut-off valve is opened to fill the installation hole to be repaired with high-pressure gas. After maintaining the pressure for a period of time and curing the repair liquid with an ultraviolet lamp, the shut-off valve is closed, the exhaust function of the electric air pump is started to deflate the airbag, and the top cover is lifted out, thus completing the repair.

[0021] The beneficial effects of this application are:

[0022] 1. First, add the seepage repair fluid into the mounting hole, then place the top cover at the mounting hole and snap it onto the casting body. Then, start the inflation function of the electric air pump. The electric air pump inflates the air bladder through the air pipe. The air bladder expands and fits tightly against the inner wall of the mounting hole to form a seal. Then, connect the air inlet end of the air supply pipe to an external compressed air source. High-pressure gas is injected into the mounting hole through the air supply pipe, thereby quickly and effectively repairing the leakage point. The air bladder can be inflated to seal mounting holes of different sizes, which is beneficial to meet the seepage repair needs of mounting holes of various sizes of casting bodies and improves the applicability.

[0023] 2. After high-pressure gas is injected into the mounting hole, the ultraviolet lamp is turned on to cure the seepage liquid in the mounting hole. There is no need to immerse the casting in hot water, which helps to improve curing efficiency and shorten the seepage time. Attached Figure Description

[0030] Reference Figure 1-4A localized seepage repair device for silicon-aluminum alloy castings includes a casting body 1 and a top cover 2. The casting body 1 has several sets of mounting holes 101. The top cover 2 is placed on the top of the casting body 1. A fixing pipe 3 is fixedly installed in the middle of the top cover 2. An air supply pipe 4 is fixedly installed inside the fixing pipe 3. Both ends of the air supply pipe 4 are provided with the fixing pipe 3. A connecting sleeve 5 is fixedly installed on the outer surface of the fixing pipe 3 below the top cover 2. An air bladder 6 is fixedly installed on the outer ring of the connecting sleeve 5. An air pipe 7 is connected to the top of the air bladder 6. An electric air pump 8 is installed through the top cover 2 at the top of the air pipe 7. A uniform head 11 is connected to the bottom of the uniform head 11. Several sets of uniform holes 12 are opened at the bottom of the uniform head 11.

[0031] First, a repair fluid is added to the mounting hole 101. Then, the top cover 2 is placed at the mounting hole 101 and snapped onto the casting body 1. Next, the inflation function of the electric air pump 8 is activated. The electric air pump 8 inflates the air bag 6 through the air pipe 7. The air bag 6 expands and tightly fits the inner wall of the mounting hole 101, forming a seal. Then, the air inlet end of the air supply pipe 4 is connected to an external compressed air source. High-pressure gas is injected into the mounting hole 101 through the air supply pipe 4, thereby quickly and effectively repairing the leakage point. The inflation of the air bag 6 can seal mounting holes 101 of different sizes, which is beneficial to meet the repair needs of mounting holes 101 of various sizes of casting bodies 1, thus improving the applicability. The high-pressure gas is delivered to the uniform head 11 through the air supply pipe 4 and evenly penetrates the repair fluid into the defects of the casting body 1 through several sets of uniform holes 12, improving the repair effect on the defects of the casting body 1.

[0032] Reference Figure 1-3 Two sets of connecting rods 9 are fixedly installed at the bottom of the connecting sleeve 5, and ultraviolet lamps 10 are fixedly installed at the bottom of the two sets of connecting rods 9; a bracket 13 is fixedly installed at the top of the top cover 2, the top of the electric air pump 8 is fixedly installed with the bracket 13, and a controller 14 is fixedly installed on one side of the bracket 13 at the top of the top cover 2, and the controller 14 is electrically connected to the electric air pump 8.

[0033] After high-pressure gas is injected into the mounting hole 101, the ultraviolet lamp 10 is turned on to cure the seepage liquid in the mounting hole 101. There is no need to immerse the casting in hot water, which helps to improve curing efficiency and shorten the seepage time. The bracket 13 strengthens the support of the electric air pump 8, and the controller 14 facilitates the operation of the electric air pump 8, which improves the practicality during use.

[0034] Reference Figure 1-3The airbag 6 is equipped with a pressure detector 15, which is connected to the controller 14. Four sets of weight blocks 17 are fixedly installed on the top of the cover 2. The pressure detector 15 monitors the pressure changes inside the airbag 6 in real time. When the controller 14 receives the pressure monitoring value from the pressure detector 15 and it reaches the preset value, it controls the electric air pump 8 to stop working, which helps to ensure the airbag 6 is sealed. The four sets of weight blocks 17 increase the gravity of the cover 2 and ensure the stability of the cover 2.

[0035] Reference Figure 1-3 A pressure detector 16 is fixedly installed at the bottom of the air supply pipe 4. The pressure detector 16 is located between the connecting sleeve 5 and the equalizing head 11, and is connected to the controller 14 via signal. A quick-connect fitting 18 is fixedly installed at the air inlet end of the air supply pipe 4. A shut-off valve 19 and a pressure reducing valve 20 are installed inside the air supply pipe 4. The shut-off valve 19 is located between the quick-connect fitting 18 and the pressure reducing valve 20. The pressure change in the mounting hole 101 is monitored in real time by the pressure detector 16. When the controller 14 receives the pressure monitoring data from the pressure detector 16, the controller will detect the pressure change. When the measured value reaches the preset value, the filling of high-pressure gas into the mounting hole 101 is stopped, which improves the safety during use. After connecting the air inlet of the air supply pipe 4 to an external compressed air source, the gas pressure entering the air supply pipe 4 is set through the pressure reducing valve 20. Then, the shut-off valve 19 is opened to fill the mounting hole 101 to be repaired with high-pressure gas. After maintaining the pressure for a period of time and curing the repair liquid through the ultraviolet lamp 10, the shut-off valve 19 is closed, the exhaust function of the electric air pump 8 is started, the air bag 6 is deflated, and the top cover 2 is lifted out, thus completing the repair.

[0036] Working principle: First, a seepage repair liquid is added into the mounting hole 101. Then, the top cover 2 is placed in the mounting hole 101 and snapped onto the casting body 1. Then, the inflation function of the electric air pump 8 is activated. The electric air pump 8 inflates the air bag 6 through the air pipe 7. The air bag 6 expands and tightly fits the inner wall of the mounting hole 101 to form a seal. Then, the air inlet end of the air supply pipe 4 is connected to an external compressed air source. High-pressure gas is injected into the mounting hole 101 through the air supply pipe 4, thereby quickly and effectively repairing the leakage point. The inflation of the air bag 6 can seal mounting holes 101 of different sizes, which is beneficial to meet the seepage repair needs of mounting holes 101 of various sizes of casting bodies 1, thus improving the applicability. After the high-pressure gas is injected into the mounting hole 101, the ultraviolet lamp 10 is turned on to cure the seepage repair liquid in the mounting hole 101. There is no need to immerse the casting in hot water, which helps to improve the curing efficiency and shorten the seepage repair time.

[0037] High-pressure gas is delivered to the uniform head 11 through the gas supply pipe 4, and the repair liquid is evenly penetrated into the defect of the casting body 1 through several sets of uniform holes 12, which improves the penetration and repair effect of the defect of the casting body 1. The support 13 strengthens the support effect of the electric air pump 8, and the controller 14 facilitates the operation of the electric air pump 8, which improves the practicality during use.

[0038] Meanwhile, the pressure changes inside the airbag 6 are monitored in real time by pressure detector 15. When the controller 14 receives the pressure monitoring value from pressure detector 15 and it reaches the preset value, it controls the electric air pump 8 to stop operating, which helps to ensure the airbag 6 is sealed. The pressure changes inside the mounting hole 101 are monitored in real time by pressure detector 26. When the controller 14 receives the pressure monitoring value from pressure detector 216 and it reaches the preset value, it stops filling the mounting hole 101 with high-pressure gas, which improves the safety during use.

[0039] In addition, the weight of the top cover 2 is increased by four sets of weighted blocks 17 to ensure the stability of the top cover 2; after connecting the air inlet of the air supply pipe 4 to an external compressed air source, the gas pressure entering the air supply pipe 4 is set by the pressure reducing valve 20, then the shut-off valve 19 is opened to fill the mounting hole 101 to be patched with high-pressure gas, the pressure is maintained for a period of time and the patching liquid is cured by the ultraviolet lamp 10, then the shut-off valve 19 is closed, the exhaust function of the electric air pump 8 is started to deflate the air bag 6, and the top cover 2 is lifted out, thus completing the patching.
