Description
Technical field
The present invention relates to a kind of life of product test device, especially one kind to renovate upset endurance testing device.
Background technology
Flip type bottle cap is referred to as renovated, extensively using with the daily product such as various bath oils, shampoo, liquid detergent.Turn over
Lid includes the top cover and bottom of integrated injection molding, in order to ensure top cover during use and bottom will not be separated from each other, is turning over
In the production process of lid, it usually needs the upset life-span between the top cover and bottom of flip cover.
Due to needing continuous flip top cover in the upset life test renovated, its switching process is a reciprocally swinging mistake
Journey, therefore the existing switching mechanism for renovating upset endurance testing device is typically driven using rotary cylinder, due to rotation
The characteristic of cylinder, switching mechanism can rapidly overturn and stop suddenly, motion mutation it is larger easily produce vibration so that renovate by
Stress outside tilting force and easily produce fracture, and then make it that the resultant error of test is larger；Simultaneously because rotary cylinder
Rotational travel is not easy to adjust so that the same testable flip-type of test device is relatively fewer.
Furthermore it is existing to renovate Turnover testing device to be used for the fixed fastener structure renovated relative complex, renovate
Fasten and dismantle cumbersome, many inconvenience are brought to production.
In addition, existing Turnover testing device of renovating can only typically detect that what is be broken in Lifetest procedure is overturn turns over
Lid, although part is renovated after the upset for having carried out specific times without being broken completely, but the connection between top cover and bottom
Structure has been destroyed, and existing Turnover testing device of renovating is difficult to detect by coming.
In view of this, the present inventor conducts in-depth research to renovating Turnover testing device, there is this case generation then.
The content of the invention
It is an object of the invention to provide a kind of test result accurately to renovate upset endurance testing device.
To achieve these goals, the present invention adopts the following technical scheme that：

State in frame, crank-rocker structure is formed between the bull stick, the link assembly and the rocking bar；
The motor, the needle protector and the detecting system communicate with the control system connect respectively.
Using above-mentioned technical proposal, the rotary motion of motor is transformed into the past physical pendulum of rocking bar by crank-rocker structure
It is dynamic, and then realize the tested upset repeatedly renovated, compared with the technical scheme that conventionally employed rotary cylinder is driven, motor
Rotation is more steady, and vibration is relatively fewer, renovates the influence for other stress being not easily susceptible to outside tilting force, test result is more
Accurately.
As a modification of the present invention, the clamping assembly includes regulating block and two one end are respectively fixedly connected with institute
The clamping bar at regulating block both ends is stated, the other end of the clamping bar is hanging, and two clamping bars are parallel to each other, and the regulating block passes through
Screw is fastened on the rocking bar.By above-mentioned improvement, between the top cover renovated is placed in into two clamping bars during test, push rod and dress
Connected between clip assembly for contact, it be that caused shake is delivered to and renovated that test device, which will not work, further improve
The accuracy of test result.
As a modification of the present invention, the link assembly includes screw rod and is respectively screw to screw at the screw rod both ends
Connector.By above-mentioned improvement, the adjustment of link assembly length can be realized by adjusting position of the connector on screw rod, is entered
And change the oscillating stroke of rocking bar so that testable flip-type is relatively more.
As a modification of the present invention, the retention mechanism includes being fixed on support in the frame, installed in institute
The guide rod on support and two sliding blocks being arranged on the guide rod are stated, screw thread rifling is provided with the guide rod, it is described
The screwed hole coordinated with the screw thread rifling is offered on sliding block, the opposite side of two sliding blocks has clamping respectively
Face.Pass through above-mentioned improvement so that retention mechanism easily can be clamped or dismantled and renovate, and be easy to use；Also cause fastening simultaneously
Mechanism goes for that various diameters are different to be renovated.

The present invention is described further with specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, what the present embodiment provided renovates upset endurance testing device, including frame 10 and control are
System (not shown), control system are conventional system, are no longer described in detail herein.
It is provided with frame 10 for the fixed retention mechanism 30 for renovating 20, the switching mechanism for renovating for driving 20 upsets
40th, the detecting system renovated the needle protector 50 of 20 bonding strengths for auxiliary judgment and whether be broken for flip cover 20
60。
It can be conventional flip structure to renovate 20, and this class formation all includes the top cover 21 and bottom of integral type connection
22, the upset for renovating 20 is top cover 21 relative to the rotation of bottom 22, the test for renovating Turnover testing device of the present embodiment
Purpose renovates whether 20 attachment structures after the upset by specific times between its top cover 21 and bottom 22 can protect for judgement
Hold normal linkage function not to be destroyed, specific upset number is renovated in test to be needed to be entered according to the requirement of specific cover-turning over products
Row determines.
Support 31, the guide rod 32 two on support 31 that retention mechanism 30 includes being fixed in frame 10 are arranged on
Sliding block 34 on guide rod 32.The opposite screw thread rifling 33 of two sections of hands of spiral is provided with guide rod 31, is offered on sliding block 34
The screwed hole coordinated with screw thread rifling 33, and two sliding blocks 34 are located at the position of both ends screw thread rifling 33 of guide rod 31 respectively
Place, by rotating guide-bar 32, can promote two move toward one anothers of sliding block 34.
The opposite side of two sliding blocks 34 has clamping face 35 respectively, it is contemplated that renovates generally pylindrical, clamping face 35
Preferably arc surface or curved surface.In use, two sliding blocks 34 are slided opposite to each other along guide rod 32, tested is then renovated 20
Bottom 22 be placed between two sliding blocks 34, then unclamp sliding block 34 cause sliding block 34 clamped in the presence of compression spring 33
Bottom 22, bottom 22 should contact with each other with the clamping face 35 of sliding block 34 after clamping.As a result of compression spring 33, can effectively delay
10 issuable vibrations of frame when rushing test device work, improve test accuracy, while convenient disassembly, suitable for it is various not
With renovating for dimensions.
Preferably, support 31 is connected with the adjustable height of the fixed form of frame 10 in the present embodiment, is specifically connected
The mode of connecing is that support 31 is fixedly mounted and takes notice of in supporting plate 11, and in opening position of the frame 10 for fixing retention mechanism 30
The fixed screw rod 12 placed vertically, fixed form of the support 31 in supporting plate 11, and fixation of the screw rod 12 in frame 10
Mode can such as be welded by the way of conventional；Then supporting plate 11 is interspersed on screw rod 12, and uses two and screw rod
