Description
Technical field
The present invention relates to auto parts machinery manufacture technical field, especially a kind of method examined for drag-line fatigue strength.
Background technology
Drag-line is a kind of manipulation being used between part linking for being widely used in the machines such as lathe, automobile, motorcycle, changed
Become the device of running speed or tractive force etc.；In the production process of drag-line, because internal stress, meeting be present in the steel for manufacturing drag-line
Drag-line is produced relaxation, fatigue, therefore, drag-line fatigue strength inspection carried out to the drag-line manufactured, can be born with appraising and deciding it
Fatigue load value；The inspection of existing drag-line fatigue strength need to purchase special equipment or drag-line is delivered to special inspection
Mechanism；Because the profit of drag-line production is originally very thin, and production cost is too high, thus reduces its manufacturer commercially
Survival ability.
The content of the invention
The present invention provides a kind of method of inspection of drag-line fatigue strength, and this method can solve existing drag-line fatigue strength
The problem of inspection causes its production cost too high.
In order to solve the above problems, the technical solution adopted in the present invention is：The method of inspection of this drag-line fatigue strength,
Using for examining the device of drag-line fatigue strength to test, the device includes support base and located at the support base one
The inclined support column of side；The support base is provided with sliding bar；One end of the sliding bar is by joining beam and one by dynamic
Power source drives the cam of rotation to be connected；The other end of the sliding bar is provided with the hook for linking drag-line；The top of the support column
End is provided with the pulley for mounting drag-line；The termination of the sliding bar, which is provided with, senses the contact that the sliding bar moves back and forth number, institute
Contact is stated with counter to be connected；
Its checking procedure is as follows：
A, the weight of predetermined weight corresponding with drag-line to be checked is selected；
B, first one end of drag-line to be checked is linked in hook, then will be mounted in the middle part of drag-line to be checked on pulley, then will drawn
The low end of rope hangs on step a weight；
C, power source is started；
D, the gravimetric value of secondary numerical value and weight that counter is shown is read, is produced.
In above-mentioned technical proposal, more specifically technical scheme can also be：The support base is provided with positioning sleeve, in institute
State and the sliding bar is installed in positioning sleeve.
Further：Angle between the support column and level is 45 degree of angles.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, due to having support base and the inclined support column located at support base side；Support base is provided with sliding bar；It is sliding
One end of lever drives the cam of rotation to be connected with one by connecting rod by power source；The other end of sliding bar is provided with to link and treated
Examine the hook of drag-line；The top of support column is provided with the pulley for mounting drag-line to be checked；Weight is provided with the low end of drag-line to be checked；It is sliding
The termination of lever is provided with the contact that sensing sliding bar moves back and forth number, and contact is connected with counter；So, according to tested drawing
Rope under the conditions of certain pulling force, do corresponding number reciprocating motion and not broken experiment condition, select corresponding to drag-line to be checked
Predetermined weight weight, the power suffered by zip to be checked is approximately equal to the weight of weight；When the wheel shaft rotation of power source, drive convex
Power is transmitted to connecting rod by wheel rotation, cam, drives sliding bar, and so as to which rotary motion is converted into moving back and forth, sliding bar drives quilt
Inspection drag-line moves reciprocatingly together, meanwhile, the sliding bar sensed in real time reciprocating motion number is passed to counter by contact, is counted
Device is recorded this reciprocating number；The gravimetric value of weight and the secondary numerical value of counter records are read, that is, obtains drag-line
The inspection of fatigue strength；To sum up, simplified structure can obtain the inspection of drag-line fatigue strength, so as to reduce production cost,
Improve the productive profit of enterprise；
2nd, because support base is provided with positioning sleeve, the sliding bar is installed in positioning sleeve；It ensure that the reliability of sliding bar；
3rd, because the angle between support column and level is 45 degree of angles；So, rational in infrastructure, the weight lifted on drag-line will not be by
To the collision of peripheral devices.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
The invention will be further described for embodiment below in conjunction with the accompanying drawings：
The method of inspection of this drag-line fatigue strength, using shown in Fig. 1 be used for examine the device of drag-line fatigue strength to test,
The device includes support base 1 and the support column 2 located at the side of support base 1；The top of support column 2 makes away from support base 1
Support column 2 is outward-dipping；Angle between support column 2 and level is 45 degree of angles；Support base 1 is provided with positioning sleeve 7, positioning sleeve
Sliding bar 8 is coated with 7；One end of sliding bar 8 is connected by the first connecting pin 91 with one end of connecting rod 10, connecting rod 10
The other end is connected by the second connecting pin 92 with cam 11；The wheel shaft of cam 11 is connected with the wheel shaft of power source 12；It is sliding
