Abstract
The invention provides a kind of elastic cylindrical pin limit mounting frock, it is arranged on support set by spacer pin through support set including last item, spring, spacer pin, support set, last item, ensure that press-fited rear elastic cylindrical pin stretches out size by spacer pin is spacing；With support set whole process protection elastic cylindrical pin end face, with last item, elastic cylindrical pin is applied the power of vertical direction, it is ensured that elastic cylindrical pin end face is without deformation；Using the lantern ring type design of last item and support set, support set slides on last item, is made the face of cylinder supporting straight pin with pounding carrying out and progressively reducing of dress by spring, so installing to together with position is simplified to by just positioning with pounding, a step completes installation.
Description
Technical field
The invention belongs to mechanical field, relate to a kind of elastic cylindrical pin limit mounting frock.
Background technology
The conventional mounting arrangements of elastic cylindrical pin is: uses hammer that elastic cylindrical pin is directed at installing hole and carries out just positioning pounding
Dress, pounds after elastic cylindrical pin is initially entered into installing hole again and installs to position.
The structure comparison of power takeoff is special, needs to install on the back-up ring above power takeoff hollow axle assembly an Elastic Circular
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 to pound through twice to install into, the most slightly larger will
Resilient key is pounded dress excessively causes outreach to cause part rejection not, even if skilled worker, part rejection rate especially
Also at 10-20%.
The reason that elastic cylindrical pin extension elongation is not easily controlled is, hole depth pin is short herein.Although can lead in theory
The degree of depth crossing control hole realizes the control to elastic cylindrical pin extension elongation, but actually the degree of depth in hole is to be difficult to accurately 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 installed to position.Hammer face and resilient key upper surface
During contact, if there being certain angle, as easy as rolling off a log causing pounds the phenomenons such as flat or flange.
Old installation method needs two steps, just positions and pounds and installs to position.If not carrying out just positioning, then resilient key cannot be consolidated
Fixed, it is easy to directly to pound and fly.Want at the beginning of position and pound and install to position and be reduced to a step, if it has to consider the extension elongation of pin
Being only 1.5-1.7 millimeter, how this positions.
Summary of the invention
It is an object of the invention to overcome prior art defect, it is provided that a kind of elastic cylindrical pin limit mounting frock, it is ensured that
Press-fited rear elastic cylindrical pin stretches out size, it is ensured that elastic cylindrical pin end face, without deformation, simplifies installation steps, and a step is complete
Become to install.
For reaching above-mentioned purpose, the present invention adopts 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 support set
Being 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, described support set beginning with bar-shaped trough, spacer pin slides in bar-shaped trough.
Further, top, described last item front end diameter is much smaller than last item diameter.
Further, described last item rear end is taper.
Further, arranging boss in the middle part of described last item, spring housing is spacing by boss at last item.
The elastic cylindrical pin limit mounting frock of the present invention, including last item, spring, spacer pin, support set, last item is through propping up
Support set is arranged on support set by spacer pin, ensure that press-fited rear elastic cylindrical pin stretches out chi by spacer pin is spacing
Very little；With support set whole process protection elastic cylindrical pin end face, with last item, elastic cylindrical pin is applied the power of vertical direction, it is ensured that elastic
Straight pin end face is without deformation；Using the lantern ring type design of last item and support set, support set is slided on last item, is made by spring
Support the face of cylinder of straight pin with pounding carrying out and progressively reducing of dress, so installing to together with position is simplified to by just positioning with pounding, one
Walk installation.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention 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: include last item 1, spring
2, 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 support set 4 front end 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, described support set 4 beginning with bar-shaped trough, spacer pin 3 slides in bar-shaped trough；Described last item 1 front end
Top diameter is much smaller than last item 1 diameter；Described last item 1 rear end is taper；Arranging boss in the middle part of described last item 1, spring 2 is enclosed within pressure
Axle 1 is spacing by boss.
The last item of new frock and support set use straight pin location, convenient disassembly, only need to change corresponding part after abrasion.
As shown in Fig. 2 a, Fig. 2 b and Fig. 3, when using new frock to carry out elastic cylindrical pin installation, 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, use hammer to pound the upper end to last item 1, after pounding and installing to position, take off frock.
Above content is further description made for the present invention, it is impossible to only assert the detailed description of the invention of the present invention
It is limited to this, for general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, also
Some simple deduction or replace can be made, all should be considered as belonging to the present invention and be determined invention by the claims submitted to
Protection domain.
