Description
Technical field
The present invention relates to detection technique fields, specifically disclose a kind of mechanism of detectable auto parts machinery.
Background technology
Auto parts and components can randomly select part after producing and be detected, and one of which detection project is
The wear-resisting property of auto parts machinery detects.So-called wearability refers to falling for the wear rate or wear intensity under regulation friction condition
Number, the rub proofness of auto parts machinery is indicated with this.Auto parts machinery is very high to the requirement of its wearability, therefore, wear-resisting property
It is an important parameter of auto parts machinery.Currently, the wearability detection device of auto parts machinery is relatively valuable and complicated for operation,
Manufacturing enterprise needs to spend higher amount of money purchase of equipment, maintained equipment and operator training.In addition, wearability detection at present
There is also more more problems for equipment, such as generated clast cannot be cleared up in time in friction process so that auto parts machinery
Friction coefficient between friction mechanism becomes larger, and leads to not obtain correct testing result, and friction mechanism is matched with automobile
Pressure between part can not be adjusted in time, can also influence the accuracy of testing result.
Application No. is the Chinese patents of 201710672025.X to disclose a kind of wear-resisting detection device of auto parts machinery, the device
Including pars contractilis, clamping device and dedusting mechanism, clast caused by friction cannot be cleared up in time by solving existing detection device
And the problem of pressure cannot be adjusted in time.But the clamping device fixed clamp in the detection device disclosed in the patent
When auto parts machinery, in detection process, clamped auto parts machinery can not achieve rotation, therefore be unable to complete detection auto parts machinery
Wearability, can only detect auto parts machinery certain a part wearability.Also, the outer surface of clamping device and auto parts machinery is deposited
It is contacting, the wearability of the contact portion can not be detected.Therefore, the detection device in the patent there is also testing results can
By the problem of property deficiency.
Invention content
The invention is intended to provide a kind of mechanism of detectable auto parts machinery, when being detected with solving existing wearability detection device
The problem of complete detection cannot being carried out to auto parts machinery.
In order to achieve the above object, base case of the invention is：The mechanism of detectable auto parts machinery, including rack, institute
It states rack and is installed with the first stepper motor, the first stepper motor is fixedly connected with output shaft, and output shaft, which is fixedly connected with, to be turned
Plate, side of the flap far from the first stepper motor are fixedly connected with telescopic cylinder, and side of the telescopic cylinder far from flap is solid
Surely it is connected with vertical pivot；It is in hollow structure inside the vertical pivot, vertical pivot inner wall slidably connects sliding block, and the sliding block is far from flexible gas
One end of cylinder is tapered, and vertical pivot side walls are connected with several slide bars perpendicular to vertical pivot central axes, and the one of each slide bar
End is fixedly connected with is fixedly connected with clamping piece with matched first wedge block of sliding block, the other end of slide bar, and adjacent first
The first spring is fixedly connected between wedge block；First piston is slidably connected in the telescopic cylinder, first piston, which is fixed, to be connected
It is connected to the First piston bar for pushing sliding block；The housing slide is connected with the second stepper motor, the second stepper motor it is defeated
Outlet is fixedly connected with pars contractilis, and the pars contractilis includes the second wedge block, the second wedge block far from the second stepper motor one

Frictional force between 28 inner wall of workpiece, improves the stability of clamping, it is thus also avoided that clamping piece 9 scratches 28 inner wall of workpiece.
Close telescopic cylinder 3 at this time, slide the second stepper motor 21 manually to the right positions of workpiece 28, using spanner or
Other tools of person reverse bolt 26 clockwise, and bolt 26 applies downward pressure to the second wedge block 24 so that the second wedge block
24 slide to the left, so that the friction plate 27 being threaded on the second wedge block 24 is close to 28 surface of workpiece, and to workpiece
28 apply pressure to the left.Start the second stepper motor 21, friction plate 27 is driven to rotate, starts to carry out 28 surface of workpiece wear-resisting
Property detection.In detection process, spanner or other tools can be used to reverse bolt 26 clockwise, increase friction plate 27 to workpiece
28 pressure applied；Spanner or other tools can also be used to reverse bolt 26 counterclockwise, in the bullet of second spring 25 to the right
Property reply force effect under, the second wedge block 24 slides to the right, and friction plate 27 moves right, reduce friction plate 27 to workpiece 28 apply
Pressure, with this realize at various pressures detect workpiece 28 wearability.
In the above process, while starting the first stepper motor 1, flap 2 is driven to rotate clockwise, so that in clamping
Workpiece 28 rotates clockwise, and friction plate 27 starts to rub with the different location of workpiece 28, different to detect workpiece 28 with this
The wearability of position improves the confidence level of testing result.Meanwhile it being fixedly connected on the first gear 18 on output shaft and starting up time
Needle rotates, due to being intermeshed between first gear 18 and second gear 19, second gear 19 starts to rotate counterclockwise, with
The coaxially connected cam 20 of second gear 19 starts to rotate counterclockwise.Cam 20 pushes second piston bar 17 to move right so that
Second piston 12 is slided to the right, and 13 volume of left chamber increases, and internal pressure reduces, and therefore, left chamber 13 forms negative pressure, by friction plate 27
It is sucked in left chamber 13 with generated dust in 28 friction process of workpiece；When cam 20 does not push second piston bar 17 to move right
When dynamic, under the elastic recovery force effect of third spring 16 to the left, second piston 12 is slided to the left, and second piston bar 17 is to moving to left
Dynamic, the air in left chamber 13 is discharged by escape pipe.Due to being equipped with the sieve for filtering dust, powder in escape pipe
Dirt stays in left chamber 13.Therefore, under the action of cam 20 and third spring 16, negative pressure is constantly formed in left chamber 13, it will
In the dust sucking left chamber 13 generated in friction process, dust is avoided to influence the detection of wearability, while dust being avoided to diffuse
The health of staff is influenced in air.
After detection, the first stepper motor 1 and the second stepper motor 21 are closed, starts telescopic cylinder 3, First piston bar
4 move down, 6 slide downward of sliding block, under the elastic recovery force effect of the first spring 10, the first wedge block 8, slide bar 7 and folder
9 inside retracted for clearance of piece is held, workpiece 28 is removed.
Mechanism after a period of use, opens the opening on 13 side wall of left chamber, is carried out to the dust in left chamber 13
Cleaning avoids dust accumulation from blocking escape pipe.
Above-described is only the embodiment of the present invention, and the common sense such as well known concrete structure and characteristic are not made herein in scheme
Excessive description.It, without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, these all do not interfere with what the present invention was implemented
