The utility model discloses a realize like this, an impeller lock sleeve dismantles structure, including locking screw, locking screw passes through screw thread installation lock sleeve, the lock sleeve roof pressure the front end of impeller, the peripheral part of lock sleeve has jack, its characterized in that: including supporting the cover, support the cover suit the lock sleeve, the trepanning diameter of supporting the cover is greater than the diameter of lock sleeve, support the cover and have the slotted hole that the circumferencial direction extends, the slotted hole with the jack of lock sleeve corresponds, locking screw passes through the tight end cover of screw thread installation top, the tight end cover of top evenly installs the puller bolt through the screw thread circumference, the interior tip of puller bolt with support the cover roof pressure.
In the above technical solution, preferably, the width of the slot hole is larger than the diameter of the insertion hole.
In the above technical solution, preferably, the support sleeve is composed of two half-tile-shaped sleeve bodies.
In the above technical solution, preferably, the support sleeve is composed of a jack sleeve and at least one gasket sleeve, and the slot is disposed on the jack sleeve.
The utility model has the advantages and effects that:
the utility model provides a new scheme, this scheme includes as the support cover that supports the basis, join in marriage the tight end cover in top of dress through the screw thread at locking screw's front end, stretch into the length of the tight end cover in top through adjustment top tightening bolt, enlarge the distance between tight end cover in top and the impeller front end, locking screw is because of there is self material stress, after being elongated by the tight end cover in top, locking stress between lock sleeve and the impeller front end is released, at this moment with the help of stretch into from the slotted hole and assist the rotatory lock sleeve of utensil with the jack complex straight-bar on lock sleeve top, can easily implement the dismantlement to the lock sleeve, this dismantlement structure can realize dismantling the impeller fast, and is simple quick, can not harm the part.

In the figure, 1, locking screw; 2. a locking sleeve; 2-1, a jack; 3. an impeller; 4. a support sleeve; 4-1, a slotted hole; 5. tightly propping the end cover; 6. and tightly pushing the bolt.
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 harmed the part, the utility model particularly provides an impeller lock sleeve dismantles structure can be dismantled the impeller light with the help of this structure, 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, an impeller lock sleeve dismounting structure includes a locking screw 1, and the locking screw 1 is fixed at the front end of a gear shaft. The locking screw 1 is provided with the locking sleeve 2 through threads, the locking sleeve 2 is combined with the locking screw 1 through threads, the locking sleeve 2 is locked at the front end of the impeller 3 through threads, the locking sleeve 2 is pressed against the front end of the impeller 3, and the periphery of the locking sleeve 2 is provided with the insertion holes 2-1. The structure is a conventional installation and connection structure of the impeller 3 and the locking sleeve 2. When the locking sleeve 2 and the impeller 3 are disassembled, the support sleeve 4 is sleeved outside the locking sleeve 2.
The diameter of the sleeve hole of the support sleeve 4 is larger than that of the locking sleeve 2, the support sleeve 4 is provided with a groove hole 4-1 extending in the circumferential direction, and the width of the groove hole 4-1 is larger than that of the jack 2-1. The slot 4-1 corresponds to the insertion hole 2-1 of the locking sleeve 2, and the correspondence is aligned, that is, when the supporting sleeve 4 is sleeved on the locking sleeve 2, a straight rod-shaped tool (such as a screwdriver) can be inserted from the slot 4-1 and combined with the insertion hole 2-1.
The locking screw rod 1 is provided with a jacking end cover 5 through threads, the jacking end cover 5 is of a disc structure and is provided with a threaded central hole, and a plurality of threaded holes are uniformly distributed around the threaded central hole. The tightening end cover 5 is assembled on the locking screw rod 1 through a threaded central hole. The tightening end cover 5 is uniformly provided with tightening bolts 6 through the circumference of the thread, and the inner end parts of the tightening bolts 6 are pressed against the support sleeve 4. Rotatory puller bolt 6, along with the length increase of puller bolt 6 screw in puller end cover 5, the distance grow between puller end cover 5 and the 3 front ends of impeller, locking screw 1 is elongated, and the stress between impeller 3 and the lock sleeve 2 is relieved, and the screwdriver can easily rotate lock sleeve 2, behind the certain angle of lock sleeve 2 rotation. Rotatory puller bolt 6, along with the length of puller bolt 6 screw in puller end cover 5 diminishes, the distance between puller end cover 5 and the 3 front ends of impeller diminishes, and locking screw 1 resumes, does not have great stress between lock sleeve 2 after rotatory certain angle this moment and the impeller 3, demolishs puller end cover 5 and support cover 4, can easily rotate and lift lock sleeve 2 off.
In order to make the structure suitable for disassembling the locking sleeves with different sizes, the supporting sleeve consists of two half tile-shaped sleeve bodies, and the installation is not limited by the diameter of the locking sleeve. In another mode, the supporting sleeve consists of a jack sleeve and at least one gasket sleeve, the slotted hole is formed in the jack sleeve, the length of the supporting sleeve can be properly formed according to the number of the gasket sleeves, and the axial position of the slotted hole can be adjusted according to needs.
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.
