Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
For solving present impeller dismantlement difficulty, and dismantle the problem that the in-process easily harms the part, the utility model particularly provides a turning handle formula compressor impeller lock sleeve extracting tool can easily dismantle the impeller with the help of this instrument, dismantles process labour saving and time saving, and is efficient, and can not harm the part. For further explanation of the structure of the present invention, the following detailed description is made with reference to the accompanying drawings:
referring to fig. 1 and 2, a tool for detaching a locking sleeve of an impeller of a rolling handle compressor comprises a rotating sleeve 1, wherein the rotating sleeve 1 is provided with an annular sleeve part 1-1 and a disc-shaped locking rotating part 1-2, and the disc-shaped locking rotating part 1-2 is fixed at the end part of the annular sleeve part 1-1. The annular sleeve part 1-1 is a steel cylindrical sleeve body, and the disc-shaped locking rotating part 1-2 is a steel disc with the same outer diameter as the annular sleeve part 1-1. In this embodiment, the annular sleeve portion 1-1 and the disk-shaped locking turn portion 1-2 are of an integral construction. In another mode, a plurality of threaded holes are processed at the end part of the annular sleeve part 1-1, the disc-shaped locking rotating part 1-2 is processed with one-to-one corresponding handle holes, and the annular sleeve part 1-1 and the disc-shaped locking rotating part 1-2 are fixed through bolts. The disk-shaped locking swivel part 1-2 has a threaded hole which is adapted to the locking screw 3 of the impeller 2.
The other end of the annular sleeve part 1-1 is provided with a top pressing sleeve 4 in a manner of rotating around itself. Specifically, one end of the annular sleeve part 1-1, which is far away from the disc-shaped locking rotating part 1-2, is provided with an annular cover 5 through threads, an annular groove is formed between the annular cover 5 and the annular sleeve part 1-1, an annular flange matched with the annular groove is arranged at the end part of the jacking sleeve 5, and the annular flange is assembled in the annular groove.
The top pressing sleeve 5, the annular sleeve part 1-1 and the threaded hole are concentric, and the rotating sleeve 1 fixes the rotating handle 6. The rotating handle 6 is welded at the side part of the annular sleeve part 1-1.
The inner sides of the top pressing sleeve 4 and the annular sleeve part 1-1 form a sleeve hole, and the diameter of the sleeve hole is larger than the outer diameter of the locking sleeve 7. The end part of the trepanning, which is far away from the threaded hole, is a trepanning opening, and the side part of the annular sleeve part 1-1 is provided with a side opening 1-3 which is communicated with the inner side and the outer side of the trepanning.
The use method of the tool comprises the following steps: the locking sleeve 7 is sleeved in a sleeve hole of the tool, a threaded hole of the tool is aligned and combined with the locking screw rod 3, the rotating sleeve 1 is rotated through the rotating handle 6, the tool integrally moves towards the end part of the impeller 2, after the jacking sleeve 4 contacts the end part of the impeller 2, the rotating sleeve 1 is continuously rotated, under the supporting action of the jacking sleeve 4 and the thread meshing action of the rotating sleeve 1, the locking screw rod 3 generates elongation deformation in the self material stress range, and the stress between the locking sleeve 7 and the end face of the impeller 2 is relieved. An inserting rod (which can be a screwdriver) passing through the side opening 1-3 of the annular sleeve part 1-1 is inserted into an inserting hole at the side part of the locking sleeve 7, and the locking sleeve 7 is rotated by a certain angle according to the disassembling direction. The rotating sleeve 1 is rotated reversely, the tool withdraws from the locking screw rod 3, when the tension stress of the locking screw rod 3 disappears, the locking sleeve 7 is rotated and withdrawn for a certain distance, so the rotating sleeve 1 can directly detach the locking sleeve 7 by the aid of the inserted rod in the withdrawing process, and the inserted rod plays a role of transferring the circumferential torsion between the rotating sleeve 1 and the locking sleeve 7.
In this embodiment, a bearing groove is formed between the end of the pressing sleeve 4 and the end of the annular sleeve portion 1-1, and a thrust ball bearing 8 is fitted in the bearing groove. The thrust ball bearing 8 can ensure that the rotating sleeve 1 can still easily rotate after the jacking sleeve 4 is contacted with the impeller 2. The end part of the top pressing sleeve 4 far away from the annular sleeve part 1-1 is provided with a rubber gasket. The rubber gasket is pasted at the end part of the top pressing sleeve 4, and the end part is contacted with the end part of the impeller 2, so that the impeller is prevented from being scratched.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
