Abstract
The utility model discloses a kind of self centering, floating indenter devices for axis and axle sleeve assembly, it include: pedestal, spring axis, guide spring, axle sleeve, spring-loaded plunger and main shaft, fixed spring axis on the pedestal is socketed with guide spring on the spring axis；It is further fixed on axle sleeve on the pedestal, two groups of spring-loaded plungers up and down are provided on the axle sleeve, have cylindric notch in the axle sleeve, the main shaft top is slidably connected with spring axis.The main shaft fits under the guidance of guide spring with axle sleeve when assembly, and until guide spring is withstood by spring-loaded plunger, main shaft is completely into axle sleeve.In assembly using the space of the annular of guide spring and shaft room ensure that main shaft and axle sleeve strictly to the heart, prevent rigid pressure from damaging structure member；By the cooperation of guide spring and spring-loaded plunger, main shaft is completely inserted into axle sleeve.The device assembly efficiency is high, and accuracy of alignment is guaranteed, and structure is simple, easy to operate, convenient for promoting the use of.
Description
Technical field
The utility model relates to mechanical assembly technique field, specifically a kind of self centering, floating for axis and axle sleeve assembly
Indenter device.
Background technique
In the actual production process, the assembly of axis and axle sleeve is conventional on Automatic manual transmission line it is difficult to ensure that coaxial precision
Structure is complicated for floating installation, and to required precision height, steel ball and its clamp system processing are complicated, and processing cost is high, and service life is but
It does not grow, it is difficult to meet the requirement of modern industrial production.
To solve the above problems, the Chinese patent of application number 2011203141770 provides a kind of adaptive centering floating
Axis is pressed into axis by the tight fit of float top board and gland by indenter device, including installation pedestal, gland and float top board
In set, the apparatus structure is simple, and convenient for handling, weight can be according to pressure size flexible design, and reliable in action is errorless.But it should
Structure is complicated for the centering body of device, and steel ball, the machining accuracy of pedestal are high, and manufacturing procedure is complicated, and not can guarantee bottom surface with
Axial accurate verticality.
Utility model content
The purpose of the utility model is to provide a kind of self centering, floating indenter devices for axis and axle sleeve assembly, to solve
The above-mentioned problems in the prior art.
To achieve the above object, the utility model provides a kind of technical solution: a kind of to make by oneself for axis with what axle sleeve assembled
Heart floating pressure head device, comprising: pedestal, spring axis, guide spring, axle sleeve, spring-loaded plunger and main shaft, the pedestal underface
Fixed spring axis and axle sleeve are fixed with two groups of spring-loaded plungers on the axle sleeve, there is notch at one, the bullet inside the axle sleeve
It is socketed with guide spring on spring axis, notch forms annular space in guide spring and axle sleeve, and the guide spring is certainly
It is not in contact with spring-loaded plunger under right state；The bottom end of the spring axis is slidably connected with main shaft top.In guide spring
Under guidance, the spring axis, main shaft and axle sleeve three cooperation can remain concentric.
Preferably, the guide spring at the end of position on axle sleeve guarantees assembly of the spring-loaded plunger can guide main shaft
It can be completely into axle sleeve.
Preferably, the width of the notch in the axle sleeve is the floating size of main shaft, and the width of notch is greater than spring
The stroke of plunger.
The utility model has the beneficial effects that the present apparatus is floating guiding, assembly precision is reduced, and in assembling process
If main shaft is such as with axle sleeve decentraction, main shaft can meet obstructions, and guide spring is compressed, and it is empty that the stage of main shaft fits into release
Between, it is withstood by spring-loaded plunger, thus reach radially adjustable, self centering effect, while rigidity also being avoided to assemble defective work piece；
And structure member is conventional machining, reduces difficulty of processing and processing cost.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model；
Fig. 2 is the shaft side figure of the utility model；
As shown, 1. pedestals, 2. spring axis, 3. guide springs, 4. axle sleeves, 5. spring-loaded plungers, 6. main shafts.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, it is clear that described embodiment is only the preferred embodiment of the utility model, rather than whole realities
Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art institute without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1: Fig. 1 and Fig. 2, a kind of self centering, floating indenter device for axis and axle sleeve assembly are please referred to, comprising:
Pedestal 1, spring axis 2, guide spring 3, axle sleeve 4, spring-loaded plunger 5 and main shaft 6, the 1 underface fixed spring axis 2 of pedestal
With axle sleeve 4, guide spring 3 is socketed on the spring axis 2, bottom end and the main shaft 6 of the spring axis 2 are slidably connected, institute
Two groups of spring-loaded plungers 5 above and below being fixed on axle sleeve 4 are stated, the guide spring 3 does not contact in its natural state with spring-loaded plunger 5,
The space of annular release is formed between guide spring 2 and axle sleeve 4；There are notch at one, the width of the notch in the axle sleeve 4
For the floating size of main shaft 6, guarantee that guide spring 3 can guide main shaft 6 completely into axle sleeve 4.Lacking in the axle sleeve (4)
Mouthful width be main shaft 6 floating size, the width of the notch is greater than the stroke of spring-loaded plunger 5, guarantee the main shaft 6 according to
Matching requirements are completely into axle sleeve 4.
The axial direction of main shaft 6 is ejected by guide spring 3 under normal conditions, radial to cooperate with 4 stage of axle sleeve, the annular release in axle sleeve
Space；In actual operation, if main shaft 6 encounters guide spring 3 and compressed in feeding, main shaft 6 is downwardly into axis leading
In the notch of set 4, if main shaft 6 and 4 decentraction of axle sleeve, main shaft 6 can meet obstructions, guide spring 3 is compressed, the rank of main shaft 6
Section fits into the space of the annular release, is withstood by spring-loaded plunger 5.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
