Description

Technical Field

[0001] The utility model belongs to the technical field of inner sleeve disassembly tools, and in particular relates to an adjustable inner sleeve disassembly tool. Background Art

[0002] Various equipment parts need to be inspected and maintained during daily use. The inner sleeve and the outer ring of the bearing need to be removed to clean the sealing parts, add lubricating oil or even replace them. However, it is extremely inconvenient to remove or install the inner sleeve and the outer ring of the bearing. In a relatively narrow space, the mechanical parts need to be removed by the action of external mechanical force, which can easily cause damage to the existing mechanical parts. For example, using a hammer to install the inner sleeve and the outer ring of the bearing can easily knock the parts rough, increase the difficulty of installation and disassembly or cause damage to the parts. In addition, due to the limitations of manual operation, this operation process is time-consuming and labor-intensive, with low operating efficiency, making it difficult to ensure the safety of maintenance personnel and increasing safety hazards for installers.

DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0016] like Figure 1-Figure 5As shown, an adjustable inner sleeve removal tool comprises a pulling screw 2, one end of which is connected to an adjusting disk 3, a plurality of arc holes 32 are opened on the adjusting disk 3, and the arc holes 32 are uniformly distributed in a ring shape in the same direction in sequence, an inner ring baffle 5 is connected to the bottom of the adjusting disk 3, the inner ring baffle 5 is composed of a plurality of arc plates 51 to form a ring, and the same gap 52 is arranged between every two adjacent arc plates 51, a connecting disk 9 is arranged at the center of the inner ring baffle 5, and slide rails 4 are uniformly arranged on the outer periphery of the connecting disk 9, a sliding rod 53 is arranged in the middle of the arc plate 51, the sliding rod 53 is slidably sleeved in the slide rail 4, and a first positioning column 10 is arranged at one end of the sliding rod 53 sleeved on the slide rail 4, and the first positioning column 10 extends into the arc hole 32; an upper baffle 1 is sleeved on the pulling screw 2, and positioning rods 6 are penetrated on both sides of the upper baffle 1, and the positioning rods 6 are connected to the adjusting disk 3; an adjusting nut 7 is threadedly sleeved on the pulling screw 2, and the adjusting nut 7 is located above the upper baffle 1.

[0017] A positioning hole 31 is provided at the center of the adjusting disk 3, and a second positioning column 11 is provided at the center of the connecting disk 9. The second positioning column 11 is sleeved in the positioning hole 31 and connected to the end of the pulling screw 2; a hand-held sleeve 8 is sleeved on the upper part of the end of the pulling screw 2 opposite to the adjusting disk 3.

[0018] Put this device into the lower edge position of the inner sleeve 12 in the bearing 13. At this time, the upper baffle 1 is against the outer ring of the bearing 13 to play a supporting role. The upper baffle 1 can be rotated before placement, and the upper baffle 1 drives the adjusting disk 3 to rotate. The cooperation of the second positioning column 11 and the positioning hole 31 can limit the adjusting disk 3 and keep it stable. In this process, the positioning rod 6 can play a positioning, supporting and fixing role, thereby improving the connection and operation effect; in this process, the pulling screw 2 and the slide rail 4 are fixed and do not rotate. The rotation of the adjusting disk 3 makes the first positioning column 10 slide in the arc hole 32, and the arc hole 32 plays a limiting and guiding role, thereby making the slide bar 53 slide in the slide rail 4, thereby driving the arc plate 51 to rotate. Since there are equidistant gaps 52 evenly distributed between adjacent arc plates 51, the inner ring baffle 5 composed of the arc plates 51 is finally contracted, which can facilitate the inner ring baffle 5 to extend into the inner sleeve 12.

[0019] After extending, the upper baffle plate 1 is rotated in the opposite direction to extend the inner ring baffle plate 5 until the inner ring baffle plate 5 contacts the inner sleeve 12 and stops. If the inner sleeve 12 is loosely fitted to the inner wall of the bearing 13, the hand-held sleeve 8 on the upper part of the pulling screw 2 can be held to directly pull the inner sleeve 12 out of the bearing 13; if the inner sleeve 12 is relatively tightly fitted to the inner wall of the bearing 13, the hand-held sleeve 8 can be held in one hand, and the pulling screw 2 can be relatively displaced by rotating the adjusting nut 7 with the other hand, thereby driving the inner sleeve 12 to be pulled out. The hand-held sleeve 8 makes it easy for personnel to hold and operate.

[0020] The utility model can drive the adjusting plate 3 by rotating the upper baffle plate 1 to make the inner ring baffle plate 5 shrink or stretch, so as to adapt to the disassembly work of the inner sleeve 12 with different diameters.
