Abstract
The invention discloses a portable dimension measurer for pantographs, which belongs to measuring tools and aims to solve problems that measuring tools are heavy, poor in effect, easy to deform, low in universality and low in accuracy when in tests for pantographs in the prior art. The portable dimension measurer for the pantographs comprises a counterweight reel and a scale strip with one end wound on the counterweight reel, and a free end of the scale strip is provided with a head positioning device used for fixing the scale strip onto a workpiece to be measured. The dimension measurer is suitable for pantograph tests in all types, is simple in structure, small and portable, high in accuracy and adaptability, capable of bringing convenience for workers to measure, saving testing time and improving production efficiency.
Description
Technical field
The present invention relates to a kind of novel multi-usage measurer, be particularly useful for all types of pantographs and detect the dimensional measurement when testing.
Background technology
Whether pantograph possesses good geometric parameter is to influence the key factor that electric locomotive is flowed.Therefore each pantograph manufacturing enterprise has all designed the complete size detection scheme of a cover and has possessed good geometric parameter to have given play to stable and outstanding usefulness to guarantee its product.
Be applied to several kinds of measurers in the pantograph manufacturing enterprise now, or be easy to generate distortion, or measured value is influenced by operating personnel's mode of operation very easily, the height of measurement bow that mostly can only be rough, the accuracy of being far from being basically.
Portable pantograph size detector of the present invention has been optimized structure, and accuracy of measurement is obviously promoted, and simple in structure, small and exquisite portable.Make things convenient for workman's detecting operation, practice thrift test period, enhance productivity.In addition, owing to set up chi head locating device, other production operation places that this detecting device can also well be applied to ordinary measring tool can't locate the time, applied widely, market outlook are wide.
Summary of the invention
The heavy deficiency that poor efficiency is yielding, universality is poor, accuracy is low of measurer when detecting test in order to overcome existing pantograph; The present invention aims to provide portable pantograph size detector, and this detecting device is applicable to all types of pantograph tests, and simple in structure, small and exquisite portable, accuracy is high; Applicability is strong; Can well make things convenient for workman's detecting operation, practice thrift test period, enhance productivity.
To achieve these goals, the technical scheme that the present invention adopted is:
A kind of portable pantograph size detector comprises that a counterweight reel and an end are wrapped in the scale strip on the counterweight reel, and its design feature is, the free end of said scale strip is provided with one scale strip is fixed on the chi head locating device on the workpiece for measurement.
Further, said chi head locating device is processed by a two-sided nylon sticking belt, and these nylon cingulum tow sides are equipped with adhesive hair and thread gluing, and the front is printed on scale.
To the scale strip location, be set with at least one locating button on the said scale strip for ease.Further, be provided with at least two projections in the said locating button, said scale strip has a plurality of holes that can cooperate the location with projection.
Said chi head locating device is fixedly connected with scale strip, and between this chi head locating device and scale strip, is provided with hard sheet.
Said counterweight reel one side is provided with a column handle specially, is convenient to after measuring end, roll scale strip.
By said structure, the present invention partly is made up of chi head locating device, scale strip, counterweight reel and locating button etc.
Chi head locating device is processed by a special two-sided nylon sticking belt; Nylon cingulum tow sides all are provided with adhesive hair and thread gluing; And the front is printed on scale, is that a right cylinder can rely on this scale to find the center line of cylinder when locating inconvenience and then realizes accurately measuring when measuring starting point, and locating device tail end and chi head sew up; A built-in fritter hard plastic sheet is with the positioning function of the common wind spring chi of performance under non-specific applications.When special measurement, nylon sticking belt is fixed on the miscellaneous part that bow maybe will measure the zero point of utilizing the adjustable characteristic of bonding position of thread gluing to adjust tape measure.
The wide 10-12mm of said scale strip, effective length is made as 3050mm, highly measures needs with the bow that rises higher most that satisfies all model pantographs; Material adopts the lightweight leather; Light weight is difficult under the rolled state producing the memory distortion, and the hole all can be pricked with the installing and locating button by the arbitrary dimension place on the scale strip in addition.
Two diameter 1mm, high 1.2mm are set in the locating button, and spacing is that the projection about 12mm is used on scale strip, positioning, and sticks bright-coloured label (like red, orange, Huang) during use on the end face.Every detecting device is joined 3 locating buttons that color is different, to satisfy the needs of conventional pantograph test item.
Compared with prior art, the invention has the beneficial effects as follows: accuracy of measurement of the present invention is obviously promoted, and simple in structure, with low cost, and it is little to take up room, easy to carry.Adopt pantograph size detector of the present invention when pantograph test, can reduce measuring error greatly, make things convenient for workman's detecting operation, practice thrift test period, enhance productivity.Portable pantograph size detector of the present invention, the special measurement instrument when not only can be used as pantograph test, other production operation places in the time of can also well being applied to ordinary measring tool and can't locating, applied widely, market outlook are wide.
Below in conjunction with accompanying drawing and embodiment the present invention is done further elaboration.

Embodiment
A kind of portable pantograph size detector, as shown in Figure 1, mainly form by chi head locating device 1, scale strip 2, counterweight reel 4 and locating button 3 four parts.
As shown in Figure 2; Chi head locating device 1 is processed by a special two-sided nylon sticking belt, and nylon cingulum tow sides all are provided with adhesive hair and thread gluing, and positive (A face among the figure) is printed on scale; When measuring starting point is that a right cylinder can rely on this scale to find the center line of cylinder when locating inconvenience and then realizes accurately measuring; Locating device tail end and chi head sew up, and a built-in fritter hard plastic sheet is with the positioning function of the common wind spring chi of performance under non-specific applications.When special measurement, the zero point of utilizing the adjustable characteristic of bonding position of thread gluing to adjust tape measure.
