Description
Technical field
The present invention relates to auto parts machinery manufacture technical field, especially a kind of device for being used to examine 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 device for being used to examine drag-line fatigue strength, and it is strong that the device can solve existing drag-line fatigue
The problem of inspection of degree causes its production cost too high.
In order to solve the above problems, the technical solution adopted in the present invention is：It is this to be used to examine drag-line fatigue strength
Device, including support base and the inclined support column located at the support base side；The support base, which is provided with, to be slided
Bar；One end of the sliding bar drives the cam of rotation to be connected with one by connecting rod by power source；The sliding bar it is another
One end is provided with the hook for linking drag-line to be checked；The top of the support column is provided with the pulley for mounting the drag-line to be checked；It is described to be checked
The low end of drag-line is provided with weight；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.
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 device for being used to examine drag-line fatigue strength shown in Fig. 1, including support base 1 and the branch located at the side of support base 1
Dagger 2；The top of support column 2 makes support column 2 outward-dipping away from support base 1；Angle between support column 2 and level is 45
Spend angle；Support base 1 is provided with positioning sleeve 7, and sliding bar 8 is coated with positioning sleeve 7；One end of sliding bar 8 passes through the first connection
Pin 91 is connected with one end of connecting rod 10, and the other end of connecting rod 10 is connected by the second connecting pin 92 with cam 11；It is convex
The wheel shaft of wheel 11 is connected with the wheel shaft of power source 12；The other end of sliding bar 8 is provided with the hook 6 for linking drag-line 5 to be checked；Support
The top of post 2 is provided with the pulley 4 for mounting drag-line 5 to be checked；Sensing sliding bar 8, which is provided with, in the termination of sliding bar 8 moves back and forth number
Contact, contact is connected with counter；
According to tested drag-line under the conditions of certain pulling force, do corresponding number reciprocating motion and not broken drag-line fatigue strength
Experiment condition, test；
Its checking procedure is as follows：
A, the weight 3 with 5 corresponding predetermined weight of drag-line to be checked is selected；
B, first one end of drag-line 5 to be checked is linked in hook 6, then the middle part of drag-line 5 to be checked is mounted on pulley 4, then
The low end of drag-line 5 to be checked is hung on to step a weight 3；
C, power source 12 is started；
D, the gravimetric value of simultaneously secondary numerical value and weight 3 that recording counter is shown is read, and the measurement unit of the gravimetric value is changed
For the measurement unit of power, produce.
So, simplified structure can obtain the inspection of drag-line fatigue strength, so as to reduce production cost, improve enterprise
The productive profit of industry.
