The existing welding is generally done manually after the inner cylinder and the outer cylinder are manually assembled. One person is required to fix the inner cylinder and the outer cylinder by hand to achieve positioning, and then welding is performed. It requires two people to operate, which is inefficient and has poor effects, and is very unfavorable for mass production. Utility model content:

[0017] For example, see Figures 1 to 3 As shown, a silencer processing device for a fan includes a fixed base plate 10, and side support frames 20 are fixed to the left and right parts of the top surface of the fixed base plate 10. The side support frames 20 include a main vertical plate 21, and the front and rear parts of the outer side walls of the main vertical plate 21 are fixed with outer support plates. The bottom surfaces of the outer support plates and the bottom surfaces of the main vertical plates 21 are welded and fixed to the top surface of the fixed base plate 10.

[0019] The lower part of the silencer inner cylinder 100 to be processed is located between the two lower clamping plates 51 of the two lower lateral adjustment mechanisms 50, and the outer sleeve of the silencer inner cylinder 100 is sleeved with the silencer outer cylinder 200. The bottom surface of the bottom end plate of the silencer outer cylinder 200 is pressed against the top surfaces of the two lower clamping plates 51, and the silencer outer cylinder 200 is located between the upper clamping plates 31 of the two upper lateral adjustment mechanisms 30.

[0020] A circular block 60 is placed in the middle of the top surface of the fixed base plate 10 between the two lower clamping plates 51 , and an adjustment support sleeve 61 is screwed onto the outer wall of the circular block 60 . The bottom end surface of the silencer inner tube 100 is pressed against the top surface of the adjustment support sleeve 61 .

[0021] The upper lateral adjustment mechanism 30 includes an upper lateral screw rod 32, which is screwed into the middle screw hole of the corresponding main vertical plate 21, and the inner end of the upper lateral screw rod 32 extends out of the inner wall surface of the main vertical plate 21 and is movably connected to the upper clamping plate 31 through a bearing. The opposite wall surfaces of the two upper clamping plates 31 are upper arc-shaped wall surfaces, on which a wear-resistant and anti-slip layer 311 is fixed, and the outer end of the upper lateral screw rod 32 extends out of the outer end of the corresponding main vertical plate 21 and is formed. There is a rotating part, and a locking nut is screwed on the upper horizontal screw rod 32, and the locking nut is pressed against the side wall of the corresponding main vertical plate 21; a horizontal guide rod 33 is fixed on the lower outer wall of the upper clamping plate 31, and the horizontal guide rod 33 is inserted into the horizontal guide through hole of the corresponding main vertical plate 21; a guide sleeve 211 is fixed on the inner wall of the horizontal guide through hole of the main vertical plate 21, and the horizontal guide rod 33 is inserted into the corresponding guide sleeve 211.

[0022] Furthermore, the lower transverse adjustment mechanism 50 includes a lower transverse adjustment screw 52, ​​which is screwed into a transverse screw-connected through hole formed in the middle of the corresponding vertical plate 40, the inner end of the lower transverse adjustment screw 52 extends out of the inner wall of the vertical plate 40 and is movably connected to the lower clamping plate 51 through a bearing, and the outer end of the lower transverse adjustment screw 52 extends out of the outer wall of the vertical plate 40 and is formed with an outer rotating part. A second locking nut is screwed onto the lower transverse adjustment screw 52, ​​and the second locking nut is pressed against a side wall of the corresponding vertical plate 40.

[0023] Furthermore, the relative wall surfaces of the two lower clamping plates 51 are arc-shaped wall surfaces, the top surface of the lower clamping plate 51 is fixed with an upper horizontal plate 53, the bottom surface of the lower clamping plate 51 is fixed with a bottom wear-resistant plate 54, the bottom surface of the bottom wear-resistant plate 54 is tightly attached to the top surface of the fixed bottom plate 10, and the top surface of the upper horizontal plate 53 is pressed against the bottom surface of the bottom end plate of the outer tube 200 of the silencer.

[0024] When the present embodiment is in use, when processing the first silencer outer tube 200 and the silencer inner tube 100, it is necessary to loosen all the locking nuts and the second locking nuts, and at the same time, place the corresponding circular block 60 on the top surface of the fixed bottom plate 10 below between the two lower clamping plates 51, press the bottom end surface of the silencer inner tube 100 against the top surface of the adjustment support sleeve 61 screwed on the circular block 60, and then rotate the two lower lateral adjustment screws 52 so that the bottom of the silencer inner tube 100 is between the two lower clamping plates 51, and the lower outer side wall of the silencer inner tube 100 is tightly against the inner side wall of the corresponding lower clamping plate 51, so that it is defined (due to the lower outer side wall of the two lower clamping plates 51 and the lower outer side wall of the silencer inner tube 100). There are vertical lines in close contact between them, and the clamping area is very small, so it can achieve a rough limit on the position, but the silencer inner tube 100 can still rotate horizontally), then, the silencer outer tube 200 is inserted into the silencer inner tube 100, and the top surface of the upper horizontal plate 53 is pressed against the bottom surface of the bottom end plate of the silencer outer tube 200 to achieve the limitation of the silencer outer tube 200, and then, the two upper horizontal adjustment screws 32 are rotated so that the silencer outer tube 200 is clamped between the two wear-resistant and anti-slip layers 311 (it has the same clamping effect as the two lower clamping plates 51 and the silencer inner tube 100, and the silencer outer tube 200 can still rotate horizontally), and then, all the locking nuts and the second locking nut are tightened.

[0025] Then, welding and fixing can be carried out. First, the contact parts of the silencer outer tube 200 and the silencer inner tube 100 are spot welded by spot welding. At this time, the positions of the two are fixed. Then, the silencer outer tube 200 and the silencer inner tube 100 are manually and gradually rotated horizontally and welded. After the welding is completed, the locking nut and the second locking nut on one side are loosened, and the lower horizontal adjustment screw 52 and the upper horizontal adjustment screw 32 on the corresponding side are rotated, so that the lower clamping plate 51 and the upper clamping plate 31 on one side can be moved outward to a certain position, and the welded product can be taken out, and the silencer outer tube 200 and the silencer inner tube 100 to be welded are placed on them, and the lower horizontal adjustment screw 52 and the upper horizontal adjustment screw 32 on one side are rotated again to make the lower clamping plate 51 and the upper clamping plate 31 on this side move inward, and finally the silencer outer tube 200 and the silencer inner tube 100 are positioned, and welding can be continued. It only requires one person to operate, and the welding effect is good.

[0026] When positioning, the height of the top surface of the support sleeve 61 can be changed by rotating the adjustment support sleeve 61, thereby changing the distance between the bottom end surface of the silencer inner tube 100 and the bottom end surface of the silencer outer tube 200 to meet the processing size requirements.
