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 Multipurpose measuring implement, be particularly useful for all types of pantographs and detect the dimensional measurement while testing.
Background technology
Whether pantograph possesses good geometric parameter is to affect the key factor that electric locomotive is flowed.Therefore each pantograph manufacturing enterprise has designed a set of complete size detection scheme and has possessed good geometric parameter to have given play to stable and outstanding usefulness to guarantee its product.
Be applied to now several measurers in pantograph manufacturing enterprise, or easily produce distortion, or measured value is affected by operating personnel's mode of operation very easily, the height of measurement bow that mostly can only be rough, the accuracy of substantially being far from being.
Portable dimension measurer for pantographs of the present invention has been optimized structure, and accuracy of measurement is obviously promoted, and simple in structure, small and exquisite portable.Facilitate workman's detection operation, save test period, enhance productivity.In addition, owing to having 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 deficiency that while in order to overcome existing pantograph, detecting test, the heavy poor efficiency of measurer is yielding, universality is poor, accuracy is low, the present invention aims to provide Portable dimension measurer for pantographs, 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 facilitate workman's detection operation, save test period, enhance productivity.
To achieve these goals, the technical solution adopted in the present invention is:
A kind of Portable dimension measurer for pantographs, comprise that counterweight reel and an end are wrapped in the scale strip on the counterweight reel, and its design feature is that the free end of described scale strip is provided with one scale strip is fixed on to the chi head locating device on workpiece for measurement.
Further, described chi head locating device is made by a two-sided nylon sticking belt, and these nylon cingulum tow sides are equipped with adhesive hair and thread gluing, and front is printed on scale.
To the scale strip location, be set with at least one locating button for convenient on described scale strip.Further, be provided with at least two projections in described locating button, described scale strip has a plurality of holes that can coordinate with projection location.
Described chi head locating device is fixedly connected with scale strip, and is provided with hard sheet between this chi head locating device and scale strip.
Described counterweight reel one side is provided with a column handle specially, is convenient to roll scale strip after measuring end.
By said structure, the present invention partly is comprised of chi head locating device, scale strip, counterweight reel and locating button etc.
Chi head locating device is made by a special two-sided nylon sticking belt, nylon cingulum tow sides all are provided with adhesive hair and thread gluing, and front is printed on scale, when measuring starting point, be that a right cylinder can rely on this scale find the center line of cylinder and then realize Measurement accuracy while locating inconvenience, locating device tail end and chi head sew up, a built-in fritter hard plastic sheet, 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 to the zero point of utilizing the adjustable characteristic of bonding position of thread gluing to adjust tape measure.
The wide 10-12mm of described scale strip, effective length is made as 3050mm, with the maximum rising bow height that meets all model pantographs, measures needs, material adopts the lightweight leather, quality is light, is difficult for producing the memory distortion under rolled state, and on scale strip, hole all can be pricked so that locating button to be installed by the arbitrary dimension place in addition.
Two diameter 1mm, high 1.2mm are set in locating button, and the projection that spacing is the 12mm left and right, for positioning on scale strip, sticks bright-coloured label (as red, orange, Huang) on end face during use.Every detecting device is joined 3 locating buttons that color is different, to meet 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, takes up room little, easy to carry.Adopt dimension measurer for pantographs of the present invention can greatly reduce measuring error when pantograph test, facilitate workman's detection operation, save test period, enhance productivity.Portable dimension measurer for pantographs of the present invention, the special measurement instrument while 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 drawings and Examples, the present invention is further elaborated.

Embodiment
A kind of Portable dimension measurer for pantographs, as shown in Figure 1, mainly be comprised of 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 made by a special two-sided nylon sticking belt, nylon cingulum tow sides all are provided with adhesive hair and thread gluing, and positive (A face in figure) is printed on scale, when measuring starting point, be that a right cylinder can rely on this scale find the center line of cylinder and then realize Measurement accuracy while locating inconvenience, locating device tail end and chi head sew up, and a built-in fritter hard plastic sheet, 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.
As shown in Figure 3, counterweight reel 4 adopts hollow-core construction, and a side arranges the column handle specially, so that roll scale strip after measuring end, the mode that is connected of scale strip end and reel is for glueing joint.
