Description

Technical Field

[0001] This utility model belongs to the field of textile machinery technology, specifically relating to a sleeve bearing removal tool. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, interweaving or sewing together one or more layers of fabric. Sewing machines can sew fabrics such as cotton, linen, silk, wool, and synthetic fibers, as well as leather. When the internal belt of the sewing machine needs to be replaced, after removing the handwheel 1, there is a limit sleeve 3 with a bearing. Figures 1 to 2 As shown, due to the limitations of the sewing machine frame 2, disassembling the bearing limiting sleeve 3 is time-consuming and difficult. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a sleeve bearing removal tool.

[0004] The specific plan is as follows:

[0005] A sleeve bearing removal tool includes a cylindrical component and a connecting piece. One end of the cylindrical component is provided with an L-shaped groove, which is engaged with the connecting piece. The other end of the cylindrical component is provided with a ring sleeve, which is fixedly sleeved on the other end of the cylindrical component.

[0006] The connecting component is a bolt or stud.

[0007] The inner diameter of the ring is the same as the inner diameter of the cylindrical component, and the outer diameter of the ring is larger than the outer diameter of the cylindrical component.

[0008] The L-shaped groove is provided on the outer wall of the cylindrical component and penetrates the outer wall of the cylindrical component.

[0009] The cylindrical component has two L-shaped grooves, which are arranged symmetrically at the center.

[0010] The ring is an iron sleeve, and the cylindrical component is a sleeve.

[0011] The ring is welded to the other end of the cylindrical component.

[0012] This utility model discloses a sleeve bearing removal tool. When removing the sleeve bearing, the set screw on the sleeve bearing is removed, and the connecting piece is installed at the set screw hole. At the same time, the cylindrical component is sleeved on the sleeve bearing, and the L-shaped groove is engaged with the connecting piece. After the engagement is completed, the ring is struck with a cylindrical bar, causing the sleeve bearing to slip off the shaft. This tool has the beneficial effects of easy disassembly and saving disassembly time. Attached Figure Description

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of this utility model, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] like Figure 1 and Figure 2 As shown, after the handwheel 1 of the sewing machine is removed, there is a limiting sleeve 3 with a bearing on the rotating shaft. The limiting sleeve 3 with bearing includes a sleeve 4 and a bearing 5. The sleeve 4 and the bearing 5 are fixedly connected. The inner ring of the bearing 5 is fitted onto the rotating shaft. The sleeve 4 is fitted onto the rotating shaft. The outer wall of the sleeve 4 is symmetrically provided with set screw holes 6. A set screw is provided in the set screw hole 6. The set screw is in contact with the rotating shaft through the set screw hole 6. The sleeve 4 is fixedly connected to the rotating shaft through the set screw.

[0020] like Figure 3 and Figure 4 As shown, a sleeve bearing removal tool includes a cylindrical component 7 and a connecting component 10. One end of the cylindrical component 7 is provided with an L-shaped groove 9, which is engaged with the connecting component 10. The other end of the cylindrical component 7 is provided with a ring sleeve 8, which is fixedly sleeved on the other end of the cylindrical component 7. The cylindrical component has two L-shaped grooves 9, which are arranged symmetrically at the center.

[0021] The connector 10 is a bolt or stud. The inner diameter of the ring sleeve 8 is the same as the inner diameter of the cylindrical component 7. The outer diameter of the ring sleeve 8 is larger than the outer diameter of the cylindrical component 7. The inner diameter of the cylindrical component 7 is 32mm and the outer diameter is 45mm. The inner diameter of the ring sleeve is 32mm and the outer diameter is 55mm.

[0022] The L-shaped groove 9 is disposed on the outer wall of the cylindrical component 7 and penetrates the outer wall of the cylindrical component 7. In this embodiment, the groove width of the L-shaped groove 9 is 6mm.

[0023] The ring 8 is an iron sleeve, and the cylindrical component 7 is a sleeve.

[0024] The ring 8 is welded to the other end of the cylindrical component 7.

[0025] The method of using the sleeve bearing removal tool is as follows:

[0026] like Figure 2 As shown, remove the set screw from the set screw hole 6 using an Allen wrench. Simultaneously, install the connector 10 into the set screw hole 6, as shown. Figure 5 As shown, the cylindrical component 7 is then fitted onto the sleeve 4, with the connector 10 positioned within the L-shaped groove 9. When the connector 10 is within the L-shaped groove 9, the cylindrical component 7 is rotated to engage the connector 10 with the L-shaped groove. Finally, one end of an iron rod or bar is pressed against the ring 8 and struck, causing the iron rod or bar to drive the cylindrical component 7 towards... Figure 5 The leftward movement, due to the action of the connecting piece 10, causes the cylindrical component 7 to move, driving the bearing-bearing limiting sleeve 3 to... Figure 5 The left side moves, and under continuous tapping, the bearing-bearing limiting sleeve 3 is completely disengaged from the rotating shaft, thereby removing the bearing-bearing limiting sleeve 3.

[0027] After the bearing-bearing limiting sleeve 3 is removed from the rotating shaft, the connector 10 is pulled out, and the cylindrical component 7 is pulled out from the sleeve 4 for use during the next disassembly.

[0028] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
