Abstract
The utility model relates to a special tool for pulling a shaft sleeve and provides a blind hole shaft sleeve pulling device which comprises a screw rod, a tool body and support feet, wherein the section of the lower part of the screw rod is in an inverted trapezoid shape, the tool body is connected with the screw rod in a sleeved way, a support body is arranged at the bottom of each support foot, and the support feet are movably connected with the tool body. With the use of the utility model, processing operation of pulling out a blind hole shaft sleeve under various complex field spaces and work conditions can be finished by pure manual operation, and the size and the surface of the inner wall of an original matrix can be also protected from destroying.
Description
Technical field
The utility model relates to a kind of specific purpose tool that pulls out axle sleeve, a kind of specifically blind hole axle sleeve driver-extractor.
Background technology
At present, in the process and assemble of plant equipment manufacturing assembling bottom bracket axle, to reprocess, change all be quite common.Because axle sleeve adopts interference or interference fits usually, is subjected to the restriction of various complicated site space and operating mode angle sometimes, take out relatively difficulty, particularly the taking-up of blind hole axle sleeve replacing is just more difficult, adopts the mechanical damage measure that it is taken out usually.If but be subjected to the restriction of the confined space and the operating mode angle of appointed condition, adopt mechanical system also can't take out axle sleeve.
Summary of the invention
The purpose of this utility model is exactly in order to overcome above-mentioned deficiency of the prior art; a kind of blind hole axle sleeve driver-extractor is provided; it is not only simple in structure, easy to use; and has a very strong versatility; can take out the axle sleeve that is pressed in the matrix effectively, protect protocorm inwall size and surface not to be destroyed simultaneously.
The purpose of this utility model realizes by following technical measures: blind hole axle sleeve driver-extractor, comprise screw rod, body of tool and spike, and its described screw rod lower section is trapezoidal; Described body of tool and screw rod socket; Described spike bottom is provided with supporter, and spike and body of tool flexibly connect.
In technique scheme, described body of tool is the hollow female thread structure, is connected with screw flight.
In technique scheme, be furnished with T type guide chute on the described body of tool, spike is provided with the T type convex body that is used for cooperating with guide chute on the body of tool slip.
The utility model beneficial effect compared with prior art is: use the utility model, not only can utilize pure manual operations to finish the process operation that pulls out the blind hole axle sleeve that rises under various complicated site space and the operating mode; Can also protect protocorm inwall size and surface not to be destroyed.

Wherein: 1. retainer nut, 2. hoisting nut, 3. plane bearing, 4. splicing sleeve, 5. screw rod, 6. locking nut, 7. body of tool, 8. axle sleeve, 9. spike, 10. supporter, 11. matrixes.
The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, present embodiment blind hole axle sleeve driver-extractor, according to the relative dimensions of axle sleeve 8 internal diameters, body of tool 7, spike 9 and the screw rod 5 of processing corresponding size, described screw rod 5 lower section are trapezoidal, are used to promote spike 9 and stretch to axle sleeve 8 bottoms.Described body of tool 7 is threaded with screw rod 5, and spike 9 flexibly connects with body of tool 7.Other supporting use parts also comprise the retainer nut 1 that is fixed on the screw rod 5, be located at body of tool 7 tops be socketed in splicing sleeve 4 on matrix 11 of locking nut 6 on the screw rod 5, frame, with the hoisting nut 2 that splicing sleeve 4 is connected by plane bearing 3, this hoisting nut 2 also is socketed on the screw rod 5.
As shown in Figure 2, body of tool 7 is the hollow female thread structure, which is provided with T type guide chute.
As shown in Figure 3, described spike 9 bottoms are provided with supporter 10, and it can reach axle sleeve 8 bottoms easily, and the support when being used for pulling out axle sleeve 8 is stressed, and spike 9 is provided with the T type convex body that is used for cooperating with guide chute on the body of tool 7 slip.
When using this blind hole axle sleeve driver-extractor, at first body of tool 7 that processes by axle sleeve 8 internal diameter sizes and spike 9 are assembled by shown in Figure 4, after finishing by assembling shown in Figure 1 with other part again, stretch into from the endoporus of axle sleeve 8, by retainer nut 1 down turn of screw rod 5, screw rod 5 bottoms are contacted with spike, spike 9 is pushed open, because spike has individual supporter, make it easily to reach the bottom of axle sleeve 8, screw nut 6 this moment again,, prevent to become flexible body of tool 7 lockings, screw hoisting nut 2 with spanner at last, along with the continuous rotation of hoisting nut 2, screw rod 5 just rises gradually, and axle sleeve 8 slowly is pulled out thereupon.
