Detailed description of the invention
Embodiments of the invention are described below in detail, and the example of described embodiment is shown in the drawings, the most from start to finish
Same or similar label represents same or similar element or has the element of same or like function.Below with reference to attached
The embodiment that figure describes is exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
In describing the invention, it is to be understood that term " on ", D score, " end ", " top ", "front", "rear",
Orientation or the position relationship of the instruction such as " interior ", " outward ", " horizontal ", " erecting " are based on orientation shown in the drawings or position relationship, are only
Specific side must be had for the ease of describing the present invention and simplification description rather than instruction or the device of hint indication or element
Position, with specific azimuth configuration and operation, be therefore not considered as limiting the invention.
The embodiment of the present invention provides a kind of novel auto-tensiometer, is the whole of tonometer of the present invention as shown in Figure 2
Body axonometric chart, the plan view of Fig. 3 correspondence tonometer, can be seen that the tonometer of the present invention itself is passed by laser displacement with reference to Fig. 3
Sensor 1 and self adaptation balancing weight 2 and cylinder mechanism three parts composition, wherein displacement transducer 1 is arranged on the end by installing rack 5
On seat 4, cylinder 3 is to be directly installed on base 4, and the present embodiment preferably carries out the fixing work of Each part with screw,
Obviously for the reasonable setting of structure, cylinder 3 is positioned at the lower section of installing rack 5.The external activity end of cylinder mechanism of the present invention includes
The fixing supporting slider mechanism being arranged on cylinder piston 31, supporting slider mechanism includes bracing frame 7 and slide bar 23, in this reality
Executing in example rotation set on bracing frame 7 and have two smooth slide bars 23, bracing frame 7 is permanently joined together with cylinder piston end 31.
It addition, as embodiments of the invention, may select and supporting slider mechanism be fabricated to integrative-structure, it is possible to select multi-part herein
Combination forms supporting slider mechanism, and structure is not limited to both the above mode, but body function and can guarantee that slide bar 23 completely runs through
Internal in balancing weight 2, and with the slide opening 21 on self adaptation balancing weight 2 surface as track, slide bar 23 can carry out upper and lower movement.Normally
Under state, slide bar 23 is in the top of slide opening 21, self adaptation balancing weight 2 plays one and supports restriction effect, and steel to be measured
During sheet surface tension, cylinder 3 runs, and its piston end 31 stretches and drives bracing frame 7 to move, and slide bar 23 drives self adaptation to join accordingly
Pouring weight 2 the most and then moves down, and when self adaptation balancing weight 2 bottom contact 22 touches steel disc surface to be measured, slide bar 23 continues
Move down the holding power making self adaptation balancing weight 2 no longer be provided by slide bar 23.When self adaptation balancing weight 2 is only by the weight of self
During power, self adaptation balancing weight 2 falls can make steel disc to produce a sag of chain on steel disc, and this sag of chain is via self adaptation balancing weight
The displacement transducer 1 of surface is recorded, and is connected to computer by sensor external union joint 8, computer directly changes
Calculate the numerical value demonstrating tension force.
Showing with reference to Fig. 4 process, when self adaptation balancing weight G has just contacted tested steel disc D surface, sensor C can record
Its height h with steel disc surface distance, when balancing weight G is only by self gravitation, falls can make steel disc D to produce one on steel disc D
Sag of chain △ h, now records the height h1 of itself and steel disc surface distance, therefore has △ h=h-h1 during sensor C postscript, this meter
Calculation process directly can be calculated by the computer being connected with sensor, and technical staff can be programmed displacement to computer in advance
Variable quantity and the capillary relative program of steel disc, make tonometer from computer while test steel disc surface displacement variable quantity
Demonstrate corresponding tension variation value.So that whole measurement process can obtain the feedback of fast accurate.
But as embodiments of the invention, the tonometer periphery of the application has protective roof structure, and protective cover is with base
Being rectangular-shaped for its one side, but be not provided with bottom surface, this is designed to ensure that tonometer internal structure can be played guarantor by protective cover
While protecting effect, do not affect contacting of balancing weight and testee.
In order to preferably embody the purposes of the present invention, can be fixed on by auto-tensiometer involved in the present invention can be one
In the X-Y-Z axle travel mechanism moved freely in fixed three dimensions, X-Y-Z axle travel mechanism can by the present invention automatically
Power meter determines in certain level height, and belt tension meter moves in this level height, it is achieved measure process.In view of
X-Y-Z axle travel mechanism is relatively easy to understand for those skilled in the art, and the application will not do and too much describe restriction, the present invention
Main protect this device can play " measurement tension force " this function under routine operation flow process, and this device measurement tension force this
During can produce obvious beneficial effect.
Additionally as another embodiment of the present invention, the shape of self adaptation balancing weight can be cylinder or can realize equally
Any regular cube of balancing weight function.
According to defect present in the prior art described in this patent background technology.The invention provides above-mentioned automatic survey to open
The tonometer of power, this device can realize the capillary fully-automated synthesis of steel disc by reasonably design, save processing greatly
Manpower and time cost, and can with more efficient accurately complete detect the capillary task of steel disc.
Additionally, due to the architectural feature advantage of tonometer of the present invention, the surface that not only can measure SMT template steel disc is opened
Power, equally measures the web tension of other surfacings.
Although the detailed description of the invention of the present invention is described in detail by the illustrative examples with reference to the present invention, but
Be it must be understood that those skilled in the art can be designed that multiple other improvement and embodiment, these improve and embodiment will
Fall within spirit and scope.Specifically, aforementioned disclosure, accompanying drawing and claim scope it
In, rational modification and improvement can be made in terms of the layout of parts and/or sub-combination layout, without departing from this
The spirit of invention.Except the modification in terms of parts and/or layout and improvement, its scope is by claims and equivalent thereof
