Description

Technical Field

[0001] This utility model relates to the field of paint protection technology, specifically a protective device for paint treatment of combustion chamber shell. Background Technology

[0002] A combustion chamber is a device in which fuel or propellant burns to generate high-temperature combustion gases. It is a combustion device made of high-temperature resistant alloy materials. Fuel burns in this chamber. It is an important component of gas turbine engines, ramjet engines, and rocket engines. For piston engines, the combustion chamber refers to the space between the top of the piston and the cylinder head after the piston reaches top dead center; the combustion chamber shell is an important part of the combustion chamber assembly.

[0003] The existing combustion chamber shell has two 3mm gaps that need to be painted. However, in the painting process, stickers are used for protection beforehand. This operation is not only cumbersome, but it is also impossible to ensure that the paint gap is consistently 3mm. Moreover, after painting one gap, manual control is required to proceed to the next gap, which reduces work efficiency. Therefore, we propose a protective device for the painting treatment of combustion chamber shells. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a protective device for spray painting of combustion chamber shell. It can automatically spray paint to protect the combustion chamber shell, solve the problem of cumbersome operation in sticker protection, ensure that the paint gap can be kept stable at 3mm, and the sealing gasket can prevent the paint from spreading to the paint tank, effectively package the stability of the paint spraying, and effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective device for spray painting of a combustion chamber shell, comprising a base plate, a combustion chamber shell, and a protective unit;

[0006] A turntable is provided above the base plate. A circular groove is opened in the middle of the turntable, and a combustion chamber shell is provided in the circular groove. A support plate is fixedly installed at one end of the turntable. Support frames are symmetrically installed on the outer side of the support plate. The lower ends of the support frames are fixedly connected to the turntable. A protective unit is provided on the inner side of the support plate. A connecting plate one and a connecting plate two are installed at the lower end of the base plate. Support seats are fixedly installed at both ends of the lower side of the connecting plate one and the connecting plate two. A connecting plate is provided between the connecting plate one and the connecting plate two.

[0007] The protective unit includes a movable frame, guide rails, and hydraulic cylinders. Guide rails are symmetrically arranged on the inner side of the support plate, and the lower ends of the guide rails are fixedly connected to the upper end of the turntable. The lower end of the movable frame is symmetrically provided with sliding grooves, and the movable frame is slidably connected to the guide rails through the sliding grooves. Hydraulic cylinders and guide rods are respectively installed at both ends of the inner side of the support plate. The output shaft of the hydraulic cylinder and the other end of the guide rod are fixedly connected to the outer end of the movable frame. Protective plates are symmetrically installed at both ends of the inner side of the movable frame. The input end of the hydraulic pump of the hydraulic cylinder is electrically connected to the output end of the external controller.

[0008] When it is necessary to spray paint on the gaps in the combustion chamber shell, the hydraulic cylinder moves the moving frame inward along the guide rail, and then brings the protective plate into close contact with the outer wall of the combustion chamber shell. With the setting of the protective unit, the combustion chamber shell can be automatically sprayed with paint for protection, which solves the problem of cumbersome operation in sticker protection and has high practicality.

[0009] Furthermore, the gap between the two protective plates forms a paint spraying groove, and a sealing gasket is fixedly connected to each of the protective plates.

[0010] The gaps between the protective plates form a stable 3mm distance for the paint spraying groove, ensuring that the paint spraying gap remains stable at 3mm. The sealing gasket prevents the paint from spreading into the paint spraying groove, effectively ensuring the stability of the paint spraying.

[0011] Furthermore, the fixing unit includes a connecting column, a hydraulic push rod, and a fixing plate. An annular groove is provided in the middle of the base plate, and a combustion chamber shell is connected in the annular groove. A connecting column is installed at the upper middle part of the base plate, and hydraulic push rods are evenly installed at the four ends of the connecting column. The output shafts of the hydraulic push rods are all fixedly connected to the fixing plate, and the input end of the hydraulic pump of the hydraulic push rod is electrically connected to the output end of the external controller.

[0012] When painting is required, the combustion chamber housing is placed in the annular groove. Then, the hydraulic push rod moves the fixing plate outward to fix the combustion chamber housing and prevent it from shaking during the painting process, which would affect the painting effect.

[0013] Furthermore, the drive unit includes a cylinder, a moving bar, and a second support plate. The cylinder is mounted on the lower end of the connecting plate one via a mounting base. The output shaft of the cylinder is fixedly connected to the moving bar. Both ends of the moving bar are slidably connected to the inner side of the second support plate. The upper end of the second support plate is fixedly connected to the lower end of the connecting plate one. The input end of the cylinder pump is electrically connected to the output end of an external controller.

[0014] The cylinder moves back and forth between the second support plate with the moving bar, providing the conditions for the rotation of the protective unit.

[0015] Furthermore, the rotating unit includes a fixed frame, a sliding block, and a rotating plate. The other end of the moving bar is fixedly connected to the outer end of the fixed frame. The sliding block is slidably connected to the inner side of the fixed frame. The upper end of the sliding block is fixedly connected to one lower end of the rotating plate, and the other lower end of the rotating plate is fixedly connected to the connecting plate.

[0016] The moving bar moves back and forth between the second support plates, causing the sliding block to move back and forth within the fixed frame, which in turn causes the rotating plate to rotate, which in turn causes the connecting plate to rotate, making it easier to rotate the turntable and thus adjust the position of the protective unit.

[0017] Furthermore, the upper end of the connecting plate is fixedly connected to the connecting shell, and an annular through groove is provided on the bottom plate, through which the connecting shell passes and is fixedly connected to the lower end of the turntable.

[0018] The rotation of the turntable adjusts the position of the protective unit, making it easier to paint another gap. This eliminates the need for manual control to paint the next gap, thus improving work efficiency.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This protective device for spray painting of combustion chamber shell has the following advantages:

[0020] 1. By setting up a protective unit, the combustion chamber shell can be automatically painted for protection, which solves the problem of cumbersome operation in sticker protection and has high practicality.

[0021] 2. The gap between the protective plates forms a stable distance of 3mm for the paint spraying groove, ensuring that the paint spraying gap can be kept stable at 3mm. The sealing gasket can prevent the paint from spreading into the paint spraying groove, effectively ensuring the stability of the paint spraying.

[0022] 3. The rotation of the turntable adjusts the position of the protective unit, making it easier to paint another gap. This eliminates the need for manual control to paint the next gap, thus improving work efficiency. Attached Figure Description

[0028] Please see Figure 1-3 This embodiment provides a technical solution: a protective device for spray painting treatment of combustion chamber shell, including a base plate 1, a combustion chamber shell 3 and a protective unit 8;

[0029] A turntable 2 is provided above the base plate 1. A circular groove is provided in the middle of the turntable 2. A combustion chamber shell 3 is provided in the circular groove. A support plate 6 is fixedly installed at one end of the turntable 2. Support frames 7 are symmetrically installed on the outer side of the support plate 6.

[0030] The protective unit 8 includes a movable frame 801, a guide rail 802, and a hydraulic cylinder 803. The inner side of the support plate 6 is symmetrically provided with guide rails 802, and the lower ends of the guide rails 802 are fixedly connected to the upper end of the turntable 2. The lower end of the movable frame 801 is symmetrically provided with sliding grooves, and the movable frame 801 is slidably connected to the guide rails 802 through the sliding grooves. The inner two ends of the support plate 6 are respectively equipped with a hydraulic cylinder 803 and a guide rod 804.

The inner two ends of the movable frame 801 are symmetrically equipped with protective plates 805. The input end of the hydraulic pump of the hydraulic cylinder 803 is electrically connected to the output end of an external controller.

[0031] When it is necessary to spray paint on the gaps in the combustion chamber housing 3, the hydraulic cylinder 803 moves the moving frame 801 inward along the direction of the guide rail 802, and then brings the protective plate 805 into close contact with the outer wall of the combustion chamber housing 3. With the setting of the protective unit 8, the combustion chamber housing 3 can be automatically sprayed with paint for protection, which solves the problem of cumbersome operation in sticker protection and has high practicality.

[0032] The gap between the two protective plates 805 forms a paint spraying groove 10, and a sealing gasket 9 is fixedly connected to each of the protective plates 805.

[0033] The gap between the protective plates 805 forms a stable distance of 3mm for the paint spraying groove 10, ensuring that the paint spraying gap can be kept stable at 3mm. The sealing gasket 9 can prevent the paint from spreading into the paint spraying groove 10, effectively ensuring the stability of the paint spraying.

[0034] The fixed unit 5 includes a connecting column 501, a hydraulic push rod 502, and a fixed plate 503. An annular groove 4 is provided in the middle of the base plate 1, and a combustion chamber shell 3 is connected in the annular groove 4.

The output shafts of the hydraulic push rods 502 are all fixedly connected to the fixed plate 503. The input end of the hydraulic pump of the hydraulic push rod 502 is electrically connected to the output end of the external controller.

[0035] When painting is required, the combustion chamber housing 3 is placed in the annular groove 4. Then, the hydraulic push rod 502 moves the fixing plate 503 outward to fix the combustion chamber housing 3, preventing the combustion chamber housing 3 from shaking during the painting process and affecting the painting effect.

[0036] The drive unit 14 includes a cylinder 141, a moving bar 142, and a second support plate 143. The cylinder 141 is mounted on the lower end of the connecting plate 11 via a mounting base.

The upper end of the second support plate 143 is fixedly connected to the lower end of the connecting plate 11. The input end of the cylinder 141 air pump is electrically connected to the output end of an external controller.

[0037] The cylinder 141 moves back and forth between the moving bar 142 and the second support plate 143, providing conditions for the rotation of the protection unit 8.

[0038] The rotating unit 15 includes a fixed frame 151, a sliding block 152 and a rotating plate 153. The other end of the moving bar 142 is fixedly connected to the outer end of the fixed frame 151.

The other lower end of the rotating plate 153 is fixedly connected to the connecting plate 16.

[0039] The moving bar 142 moves back and forth between the second support plate 143, causing the sliding block 152 to move back and forth within the fixed frame 151, which in turn causes the rotating plate 153 to rotate, which in turn causes the connecting plate 16 to rotate, making it easier to rotate the turntable 2 and thus adjust the position of the protective unit 8.

[0040] The upper end of the connecting plate 16 is fixedly connected to the connecting shell 17. An annular through groove is provided on the bottom plate 1, and the connecting shell 17 passes through the annular through groove and is fixedly connected to the lower end of the turntable 2.

[0041] The rotation of turntable 2 adjusts the position of protective unit 8, making it easier to spray paint on another gap. This eliminates the need for manual control to spray paint the next gap, thus improving work efficiency.

[0042] The working principle of the protective device for spray painting of combustion chamber shell provided by this utility model is as follows: When spray painting is required, the combustion chamber shell 3 is placed in the annular groove 4. Then, the hydraulic push rod 502 moves the fixing plate 503 outward to fix the combustion chamber shell 3, preventing it from shaking during the spray painting process and affecting the spray painting effect. When it is necessary to spray paint on the gaps on the combustion chamber shell 3, the hydraulic cylinder 803 moves the moving frame 801 inward along the direction of the guide rail 802, thereby bringing the protective plate 805 into close contact with the outer wall of the combustion chamber shell 3. Through the setting of the protective unit 8, the combustion chamber shell 3 can be automatically sprayed with paint for protection, solving the problem of cumbersome operation in sticker protection, and has high practicality. The gaps between the protective plates 805 form the spray painting groove 1. The stable distance of 0 is 3mm, ensuring that the paint gap can be kept stable at 3mm. The sealing gasket 9 can prevent the paint from spreading to the paint tank 10, effectively packaging the stability of the paint spraying. The cylinder 141 moves back and forth between the moving bar 142 and the second support plate 143, providing conditions for the rotation of the protective unit 8. The moving bar 142 moves back and forth between the second support plate 143, causing the sliding block 152 to move back and forth within the fixed frame 151, which in turn causes the rotating plate 153 to rotate, which in turn causes the connecting plate 16 to rotate, making it easier to rotate the turntable 2, thereby adjusting the position of the protective unit 8. The rotation of the turntable 2 adjusts the position of the protective unit 8, making it easier to spray paint on another gap, solving the problem of needing manual control to spray paint the next gap, and improving work efficiency.
