Description
Technical Field
[0001] This utility model relates to the technical field of muffler processing equipment, and in particular to a cylinder grinding device for muffler processing. Background Technology
[0002] A muffler is a device used to reduce airflow noise, primarily used in applications such as internal combustion engines, compressors, and ventilation systems that generate aerodynamic noise. Its working principle involves acoustic impedance matching, sound-absorbing material attenuation, and airflow path optimization to convert broadband noise generated by high-speed airflow (such as exhaust knocking and vortex noise) into heat energy or reflect it to cancel it out, thereby achieving noise reduction.
[0003] In the manufacturing process of mufflers, surface grinding of the cylinder is crucial, primarily used to remove weld oxide layers, burrs, and surface unevenness to ensure the accuracy of subsequent painting or assembly. However, existing grinding devices have two major problems: First, they cannot precisely adjust the grinding thickness, leading to over-grinding or under-grinding, affecting the uniformity of the cylinder wall thickness; second, their reliance on clamping at both ends makes it difficult to fully grind both ends of the cylinder, requiring repeated disassembly and adjustment, thus reducing efficiency.

[0029] Example 1:
[0030] Reference Figures 1-6This is the first embodiment of the present invention, which provides a cylinder grinding device for muffler processing. It includes a base plate 1, a fixing frame 2 fixed to the top of the base plate 1, an adjusting component 3 on one side of the fixing frame 2, a driving component 4 on one side of the adjusting component 3, a connecting component 5 at the bottom of the driving component 4, a grinding component 6 for grinding the surface of the muffler cylinder at the bottom of the connecting component 5, a moving component 7 at the top of the base plate 1, an expansion component 8 for expanding and fixing the cylinder at the top of the moving component 7, and a first set of... The second set of expansion components 8 used in expansion component 8; by setting the fixing frame 2, the adjustment component 3 can be easily installed. By setting the adjustment component 3, the drive component 4 can be easily driven to adjust the height. The drive component 4 is designed to facilitate the movement of the connecting component 5 and the grinding component 6. The connecting component 5 is designed to facilitate the connection between the drive component 4 and the grinding component 6, and also to prevent damage to the grinding disc. The grinding component 6 consists of a third motor and a grinding disc, which facilitates the grinding of the muffler cylinder. The rotation of the third motor drives the grinding disc to rotate, and after the grinding disc rotates, the surface of the cylinder can be ground.
[0031] The adjustment component 3 includes a first connecting block 31 that slides on the inner wall of the fixed frame 2, and the first connecting block 31 is located on one side of the drive component 4. The inner wall of the first connecting block 31 is threaded with a first threaded rod 32, and the upper end of the first threaded rod 32 is fixed with a turntable 33.
[0032] By setting the fixed frame 2, the first connecting block 31 can slide easily. The cooperation between the turntable 33 and the first threaded rod 32 can easily drive the first connecting block 31 to move within the fixed frame 2, thereby easily driving the first motor 41 to lift and lower.
[0033] The expansion assembly 8 includes multiple sets of mounting brackets 81 disposed on the top of the movable part 7. Each set of mounting brackets 81 has a cylinder 82 fixed to its inner wall. The piston rod of the cylinder 82 is fixed to a connecting sleeve 85. A connecting plate 83 is fixed to one side of the mounting bracket 81. Multiple sets of expansion plates 84 for supporting the inner wall of the cylinder slide on the inner wall of the connecting plate 83. Multiple sets of adjusting plates 86 rotate on the inner wall of each set of expansion plates 84, and the inner wall of the adjusting plate 86 is rotatably connected to the outer side of the connecting sleeve 85.
[0034] By setting the mounting bracket 81, the cylinder 82 can be easily fixed. The cylinder 82 is designed to facilitate the movement of the connecting sleeve 85 by driving the piston rod. By setting the connecting sleeve 85, it can be easily connected to multiple sets of adjusting plates 86, thereby facilitating the movement of multiple sets of expansion plates 84 along the inner wall of the connecting plate 83. The multiple sets of expansion plates 84 are designed to facilitate the support and fixation of the inner wall of the muffler cylinder, and facilitate the grinding disc to perform comprehensive grinding on the surface of the cylinder.
[0035] Example 2:
[0036] This is the second embodiment of the present invention, which is based on the previous embodiment.
[0037] Specifically, the driving component 4 includes a first motor 41 fixed to one side of the first connecting block 31. The output end of the first motor 41 is fixed with a second threaded rod 42 installed laterally. The outer side of the second threaded rod 42 is threadedly connected with a threaded sleeve 43, and the outer side of the threaded sleeve 43 is slidably connected to the inner wall of the fixing frame 2.
[0038] By setting the first motor 41, the second threaded rod 42 can be easily driven to rotate. After the second threaded rod 42 rotates, it can drive the threaded sleeve 43 to move. The threaded sleeve 43 is designed to facilitate the movement of the connecting piece 5. Because the threaded sleeve 43 is long, when the first connecting block 31 drives the first motor 41 and the second threaded rod 42 to move down, the threaded sleeve 43 will not detach from the fixed frame 2, preventing the second threaded rod 42 from driving the threaded sleeve 43 to rotate. Therefore, the threaded sleeve 43 will only move laterally.
[0039] Specifically, the connector 5 includes a connecting post 51 fixed to the bottom of the threaded sleeve 43, a connecting tube 52 slidably connected to the outside of the connecting post 51, a first spring 53 fixed to the inner wall of the connecting tube 52, and the upper end of the first spring 53 fixedly connected to the lower end of the connecting post 51, and the bottom of the connecting tube 52 is located at the top of the grinding part 6.
[0040] By using the connecting post 51, connecting pipe 52 and first spring 53 together, the connection between threaded sleeve 43 and grinding part 6 can be facilitated. It should be noted that the first spring 53 has a high hardness. When the grinding disc encounters small welding slag on the surface of the cylinder, the first spring 53 will not retract. When the grinding disc encounters larger welding slag, the first spring 53 will retract, thus avoiding damage to the grinding disc.
[0041] Specifically, a second connecting block 9 slides on the inner wall of the fixing frame 2, and one side of the second connecting block 9 is rotatably connected to the other end of the second threaded rod 42. A slide rod 10 slides on the inner wall of the second connecting block 9, and the lower end of the slide rod 10 is fixedly connected to the outer side of the fixing frame 2.
[0042] By setting the second connecting block 9, the stability of the second threaded rod 42 can be easily improved. By setting the slide bar 10, the second connecting block 9 can be easily moved up and down.
[0043] Specifically, the top of the grinding part 6 is provided with multiple sets of support frames 11, the inner walls of the multiple sets of support frames 11 are all rotatably limited by a limit tube 12, the inner wall of the limit tube 12 is slidably limited by a limit post 13, and the outer sides of the limit tube 12 and the limit post 13 are all fitted with a second spring 14.
[0044] By setting the support frame 11, multiple sets of limiting tubes 12 can be rotated easily. By setting the limiting tubes 12, the limiting post 13 can be slid easily. The limiting post 13 is rotatably connected to the bottom of the threaded sleeve 43. The design of the second spring 14 facilitates the buffering and rebound of the limiting post 13, improving the stability when the threaded sleeve 43 is connected to the grinding part 6.
[0045] Example 3:
[0046] This is the third embodiment of the present invention, which is based on the first two embodiments.
[0047] Specifically, the movable component 7 includes a second motor 71 fixed to one side of the base plate 1. The output end of the second motor 71 is fixed with a third threaded rod 72 through the inner wall of the base plate 1. The outer side of the third threaded rod 72 is threadedly connected to a movable plate 73. The bottom of the movable plate 73 is slidably connected to the inner wall of the base plate 1, and the top of the movable plate 73 is fixedly connected to the outer side of the mounting bracket 81.
[0048] By setting the second motor 71, the third threaded rod 72 can be easily driven to rotate. By setting the third threaded rod 72, the movable plate 73 can be easily moved on the base plate 1, and thus the multiple sets of mounting brackets 81 can be easily moved. The other end of the third threaded rod 72 is rotatably connected to one side of the baffle 16.
[0049] Specifically, two connecting rods 15 are fixed on one side of the base plate 1, and the outer side of the connecting rods 15 is slidably connected to the inner wall of the movable plate 73. A baffle 16 is slidably connected to the outer side of the other end of the connecting rods 15, and the bottom of the baffle 16 is fixedly connected to the top of the base plate 1.
[0050] By using the connecting rod 15 and the baffle 16 together, the stability of the moving plate 73 can be easily improved.
[0051] In use, first, the second motor 71 is turned on. After the second motor 71 starts, it drives the third threaded rod 72 to rotate. The rotation of the third threaded rod 72 drives the moving plate 73 to move. After the moving plate 73 moves, it drives the expansion assembly 8 to move, which makes it easy for the muffler cylinder to be placed outside the two sets of expansion assemblies 8. Then, the two sets of cylinders 82 are turned on. After the two sets of cylinders 82 start, they drive the connecting sleeve 85 to move. The movement of the connecting sleeve 85 drives the adjusting plate 86 to move. The movement of the adjusting plate 86 drives multiple sets of expansion plates 84 to move outward along the connecting plate 83. After the connecting plate 83 moves outward, it can support the inner wall of the muffler cylinder, and then fix it. After fixing, After completion, the turntable 33 is rotated, which drives the first threaded rod 32 to rotate. The rotation of the first threaded rod 32 drives the first connecting block 31 to move downward. After the first connecting block 31 moves downward to the appropriate position, the position of the grinding part 6 can be adjusted. At this time, the grinding part 6 and the first motor 41 are turned on at the same time. The rotation of the grinding part 6 drives the grinding disc to rotate, and the rotation of the first motor 41 drives the second threaded rod 42 to rotate. The rotation of the second threaded rod 42 drives the threaded sleeve 43 to move. The movement of the threaded sleeve 43 drives the connecting column 51, the connecting pipe 52, the first spring 53 and the grinding part 6 to move, thereby grinding the surface of the cylinder and improving the practicality of the device.
[0052] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
