Abstract
This utility model provides a kind of elastic cylindrical pin limit mounting frock, be arranged on support set by spacer pin through support set including last item, spring, spacer pin, support set, last item, by spacer pin it is spacing ensure that press-fit after the completion of elastic cylindrical pin stretch out size；With support set whole process protection elastic cylindrical pin end face, apply the power of vertical direction to elastic cylindrical pin with last item, it is ensured that elastic cylindrical pin end face is without deformation；Designed using the lantern ring type of last item and support set, support set slides on last item, by spring so that supporting the face of cylinder of straight pin progressively to reduce with the carrying out for pounding dress, so just positioned and pounded and being attached to position and being simplified to together, a step completes installation.
Description
Technical field
This utility model belongs to mechanical field, is related to a kind of elastic cylindrical pin limit mounting frock.
Background technology
The conventional mounting arrangements of elastic cylindrical pin are：Elastic cylindrical pin alignment installing hole is carried out just positioning using hammer to pound
Dress, pounds after elastic cylindrical pin is initially entered into installing hole again and is attached to position.
The structure of power takeoff is more special, needs an Elastic Circular is installed on the back-up ring above the hollow shaft assembly of power takeoff
Pin；This elastic cylindrical pin needs to stretch out back-up ring plane 1.5-1.7 millimeter, and bullet after having strict installation requirement, i.e. installation
The upper plane of property pin can not occur pounding the phenomenons such as flat, flange.
For These characteristics, the installation process of this elastic cylindrical pin needs workman Jing to pound twice to install into, it is firmly slightly larger will
Resilient key is pounded dress excessively causes outreach not enough to cause part rejection, even special skilled worker, part rejection rate
Also in 10-20%.
The reason for elastic cylindrical pin extension elongation is not easily controlled is that hole depth pin is short herein.Although can lead in theory
Cross the depth of control hole to realize the control to elastic cylindrical pin extension elongation, but the depth in actually hole is to be difficult precise control
, and the lower end in hole is the conical surface, is not appropriate for for spacing elastic cylindrical pin.
Old installation method is that frock ensures to position at the beginning of resilient key, and hammer is pounded and is attached to position.Hammer face and resilient key upper surface
During contact, if certain angle is then easy to cause to pound the phenomenons such as flat or flange.
Old installation method needs two steps, just positions and pounds and is attached to position.If not carrying out just positioning, resilient key cannot be consolidated
It is fixed, it is easy to directly to pound winged.Want to position at the beginning of and pound to be attached to position and be reduced to a step, if it has to consider the extension elongation of pin
Only 1.5-1.7 millimeters, how this positions.
Utility model content
The purpose of this utility model is to overcome prior art defect, there is provided a kind of elastic cylindrical pin limit mounting frock,
Ensure that elastic cylindrical pin after the completion of press-fiting stretches out size, it is ensured that elastic cylindrical pin end face simplifies installation steps without deformation, and one
Step completes to install.
To reach above-mentioned purpose, this utility model is adopted the following technical scheme that：
A kind of elastic cylindrical pin limit mounting frock, including last item, spring, spacer pin, support set；Last item passes through support set
It is arranged on support set by spacer pin, last item can slide in support set, and spring is arranged between last item and support set,
Support set front end offers the through hole that can accommodate elastic cylindrical pin, and the top of last item front end extrudes elastic cylindrical pin through through hole.
Further, bar-shaped trough is begun with the support set, spacer pin slides in bar-shaped trough.
Further, last item front end top diameter is much smaller than last item diameter.
Further, the last item rear end is taper.
Further, boss is set in the middle part of the last item, and spring housing is spacing by boss in last item.
Elastic cylindrical pin limit mounting frock of the present utility model, including last item, spring, spacer pin, support set, last item are worn
Cross support set to be arranged on support set by spacer pin, by spacer pin it is spacing ensure that press-fit after the completion of elastic cylindrical pin stretch
Go out size；With support set whole process protection elastic cylindrical pin end face, apply the power of vertical direction to elastic cylindrical pin with last item, it is ensured that
Elastic cylindrical pin end face is without deformation；Designed using lantern ring type of the last item with support set, support set slides on last item, by spring
So that support the face of cylinder of straight pin progressively to reduce with the carrying out for pounding dress, so just positioned and pounded and be attached to position and be simplified to one
Rise, a step completes to install.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail：
As shown in Figure 1 a, 1 b, a kind of elastic cylindrical pin limit mounting frock, it is characterised in that：Including last item 1, spring
2nd, spacer pin 3, support set 4；
Last item 1 is arranged on support set 4 through support set 4 by spacer pin 3, and last item 1 can slide in support set 4,
Spring 2 is arranged between last item 1 and support set 4, and 4 front end of support set offers the through hole that can accommodate elastic cylindrical pin 5, last item
The top of 1 front end extrudes elastic cylindrical pin 5 through through hole.
Further, bar-shaped trough is begun with the support set 4, spacer pin 3 slides in bar-shaped trough；1 front end of the last item
Top diameter is much smaller than 1 diameter of last item；1 rear end of the last item is taper；Boss is set in the middle part of the last item 1, and spring 2 is enclosed within pressure
Axle 1 is spacing by boss.
The last item of new frock adopts cylinder finger setting, convenient disassembly only need to change corresponding part after abrasion with support set.
As shown in Fig. 2 a, Fig. 2 b and Fig. 3, when elastic cylindrical pin installation is carried out using new frock, first by elastic cylindrical pin 5
Load the hole on support set 4, then the elastic cylindrical pin 5 of support set will be stretched out to the installing hole on its part 6.Keep Vertical Square
To pounding the upper end to last item 1 using hammer, frock removed after pounding and being attached to position.
Above content is further detailed description of the utility model, it is impossible to assert concrete reality of the present utility model
The mode of applying is only limitted to this, for this utility model person of an ordinary skill in the technical field, new without departing from this practicality
On the premise of type is conceived, some simple deduction or replace can also be made, this utility model should be all considered as belonging to by being carried
Claims of friendship determine utility model protection scope.
