Description

Technical Field

[0001] This utility model relates to the field of muffler processing technology, and in particular to a support tool for grinding the weld seam of a muffler. Background Technology

[0002] like Figure 4 The diagram shows a three-dimensional structure of a gas venting silencer. The silencer consists of a pipe 1 with vent holes on its outer circumference. The pipe 1 is formed by bending and welding. An upper end cap 10 is welded to the upper end of the pipe 1, and a lower end cap 11 is welded to the lower end. An air inlet pipe 12 is connected to the lower end of the lower end cap 11, and a flange 13 is welded to the lower end of the air inlet pipe 12. The upper surface of the upper end cap 10 has a convex arc-shaped structure. The various components of the silencer are fixed together by welding. To ensure welding quality, the weld seams need to be ground using an angle grinder after welding. Currently, the flange 13 is placed on the ground before grinding. However, the flange 13 has a small area, resulting in poor stability and a risk of the silencer tipping over during grinding. Utility Model Content

[0003] This utility model provides a support tool for grinding the weld seam of a muffler, which overcomes the shortcomings of the prior art and solves the safety risks that exist when grinding the weld seam, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technology is proposed to be adopted: A support for grinding the weld seam of a muffler includes a rectangular base plate with four mounting plates attached to it by screws. A lead screw is welded to each mounting plate, and a threaded sleeve is threaded onto the lead screw. An end plate is located at the upper end of the threaded sleeve, and an eyelet is formed on the end plate. An inner rod passes through the eyelet, and a limit nut is threaded onto the lower end of the inner rod. The limit nut is located inside the threaded sleeve and below the end plate. An upper plate is welded to the upper end of the inner rod, and an upper extension arm is welded to the upper end. A hinge seat is rotatably mounted on the upper end of the upper extension arm via a pivot, and an upper plate is welded to the upper end of the hinge seat. A limit shell is formed on the upper plate.

[0005] Furthermore, the limiting shell has a convex arc-shaped structure.

[0006] Furthermore, two pairs of limiting screws are connected to the rectangular base plate by threads. Each pair of limiting screws is movably provided with a limiting plate, and a pair of constraint holes are opened on the limiting plate. The limiting screws pass through the constraint holes.

[0007] Furthermore, an arc-shaped groove is provided on the lower wall of the limiting plate.

[0008] Furthermore, a pair of connecting screws are threaded onto the rectangular base plate, and an inner top plate is eccentrically mounted on the connecting screws. The outer periphery of the inner top plate abuts against the outer end face of the limiting plate.

[0009] The advantages of the above technical solution are: This invention uses a rectangular base plate and top plate to limit the position of the muffler, ensuring its stability and safety when placed vertically. Vertical placement facilitates grinding of welds at various locations. While horizontal placement addresses safety concerns, it hinders grinding and requires rotation during the grinding process. This new device not only ensures vertical placement for easy grinding but also guarantees safety during the grinding process.

[0010] In addition, this utility model further ensures the stability and safety of the muffler after placement by setting a pair of limiting plates to limit the flange. Attached Figure Description

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will provide a further detailed description of this utility model in conjunction with the accompanying drawings.

[0013] Figure 2 A three-dimensional structure of one embodiment is shown. Figure 2 .

[0014] Figure 3 A three-dimensional structural diagram of the limiting plate is shown.

[0015] Figure 4 A three-dimensional structural diagram of the muffler is shown. Detailed Implementation

[0016] like Figures 1-4As shown, a support tool for grinding the weld seam of a muffler includes a rectangular base plate 3. Four mounting plates 2 are installed on the rectangular base plate 3 by screws. A lead screw 20 is welded to the mounting plate 2. A threaded sleeve 21 is threadedly connected to the lead screw 20. An end plate is provided at the upper end of the threaded sleeve 21. An eye is opened on the end plate. An inner rod is inserted through the eye. A limit nut is threadedly connected to the lower end of the inner rod. The limit nut is located inside the threaded sleeve 21 and below the end plate. An upper plate 22 is welded to the upper end of the inner rod. An upper extension arm 23 is welded to the upper plate 22. A hinge seat 25 is rotatably provided at the upper end of the upper extension arm 23 via a rotating shaft 24. An upper plate 26 is welded to the upper end of the hinge seat 25. A limit shell 27 is formed on the upper plate 26. The limit shell 27 has a convex arc-shaped structure.

[0017] Two pairs of limiting screws 34 are threadedly connected to the rectangular base plate 3. Each pair of limiting screws 34 is movably provided with a limiting plate 33. A pair of constraint holes 35 are opened on the limiting plate 33. The limiting screws 34 pass through the constraint holes 35. An arc groove 36 is opened on the lower wall of the limiting plate 33. A pair of connecting screws 31 are threadedly connected to the rectangular base plate 3. An inner top plate 30 is eccentrically rotatably provided on the connecting screws 31. A holding rod 32 is eccentrically welded on the inner top plate 30. The outer periphery of the inner top plate 30 abuts against the outer end face of the limiting plate 33.

[0018] In this embodiment, during operation, the operator places the welded muffler flange 13 downwards on the rectangular base plate 3, and then rotates the inner top plate 30 by holding the rod 32. When the inner top plate 30 rotates, its outer periphery abuts against the outer wall of the limiting plate 33, thereby causing the limiting plate 33 to move inwards, so that the flange 13 is located in the arc groove 36, and the arc surface of the arc groove 36 abuts against the outer periphery of the flange 13. In this way, the stability of the connection between the lower end of the muffler and the rectangular base plate 3 is improved.

[0019] The operator then places the upper plate 26 on the upper cover 10 of the muffler, ensuring the upper surface of the upper cover 10 abuts against the inner wall of the limiting shell 27. Each threaded sleeve 21 is then rotated around the pivot 24 to ensure coaxiality between each sleeve and the lead screw 20. The sleeves 21 are rotated one by one until the upper plate 26 is horizontal. Afterward, the weld seams are ground. To achieve a horizontal position, the sleeves 21 can be rotated simultaneously or one by one until a horizontal state is reached.

[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
