Abstract
The invention discloses a tension detecting device, comprising an upper pressing plate, a lower pressing block, paired bolts and a connecting screw rod, wherein the upper side face of the lower pressing block is provided with a square slot for communicating the left side face and the right side face of the lower pressing block, and the upper pressing plate and the lower pressing block are fixed through the bolts; the lower side face of the square slot and the lower side face of the upper pressing plate positioned on the lower side face of the square slot form a seal face of the upper side face and the lower side face of a detected fixed part; the paired bolts are respectively positioned on opposite positions at front and back sides of the square slot; and the left end of the connecting screw rod is fixed with the lower pressing block through a threading structure, the right end of the connecting screw rod is fixed with a measuring head of a tensometer through a threading structure, and the central axis of the connecting screw rod is consistent with the central axis of the measuring head of the tensometer. The tension detecting device disclosed by the invention has a simple structure and is convenient to use; and by adopting the tension detecting device, the detected fixed part can be ensured to be effectively fixed without generating additional force on a detected movable part, the accuracy of the force application direction can be improved when the detected part is detected, the measurement process is convenient, and the measurement precision is improved.
Description
Technical field
The present invention relates to stretching force detecting apparatus, relate in particular to the stretching force detecting apparatus that a kind of adaptive tautness meter uses.
Background technology
Tautness meter is small-sized easy thrust, pull test instrument; It has high precision, advantage easy to operate and easy to carry, and a peak value blocked operation knob is arranged, and can do indication of loading peak value and the indication of continuous loading value.In the factory, usually use tautness meter that goods or parts are carried out simple pulling force characteristic detection; During use, the measuring head of fixture and tautness meter is fixed, the central axial direction pulling movable part along the tautness meter measuring head obtains measurement result.The measuring head of tautness meter is a helical structure; The parts that are used for fixing measuring head and fixture of its outfit are generally hook; The parts such as line body that when practical operation is used, often need increase other are fixedly connected, and troublesome poeration and the last application of force direction of very difficult assurance are consistent with the measuring head central axial direction.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art; The present invention provides a kind of stretching force detecting apparatus simple in structure, easy to use, cooperates tautness meter to use, and can fix seized fixture fast; Make things convenient for the measurement of pulling force, improve the accuracy of application of force direction.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of stretching force detecting apparatus; Comprise top board, lower lock block, paired bolt and connecting screw rod; On the upper side of lower lock block, be provided with the square groove that is communicated with its left and right sides face; Through bolt, the downside of the downside of square groove and position top board on it constitutes the seized fixture seal face of side up and down between top board and the lower lock block, and paired bolt lays respectively on the relative position of both sides, square groove front and back; Connecting screw rod left end and lower lock block are fixed through helicitic texture, and right-hand member and tautness meter measuring head are fixed through helicitic texture, and its central axis is consistent with tautness meter measuring head central axis.
In this device, the left and right directions of square groove and connecting screw rod central axial direction, tautness meter measuring head central axial direction are consistent, guarantee can not occur in the use system deviation of direction; During use, seized fixture is placed in the square groove, is covered with top board again,, guarantee that seized fixture can secure fixation, seized movable part is not produced additional force simultaneously, make and detect accurately through bolted; And because the structure of top board and lower lock block, when it was carried out the application of force, directivity was much more accurate than adopting hook structure.
Preferably, the quantity of said bolt is a pair of; This is that this case structure of design equally can be not excessive in view of the above, there is no need to design too much bolt quantity because this body structure of tautness meter is less, and detected pieces also can be not excessive; Paired structure Design, be for make seized fixture when clamping stressed evenly, do not produce angular difference; Bolt is preferably selected the structure that is easy to manually tighten for use, such as selecting for use bolt head to have two big structures of stress surface relatively.
As a kind of preferred structure, the width of said square groove fore-and-aft direction is greater than more than the seized fixture width 1mm; Can not receive ambient pressure to guarantee seized fixture in the left and right sides; But can not be excessive, accurate with the directivity that guarantees the application of force.
As a kind of preferred structure, said top board and lower lock block all are the square body structure; This is because the square body structure is easy to processing.
Beneficial effect: stretching force detecting apparatus provided by the invention; Simple in structure, easy to use; Can guarantee that seized fixture can not produce additional force to seized movable part in effectively fixing; Application of force direction accuracy in the time of can improving simultaneously the detected pieces detection is convenient for measuring process, improves measuring accuracy.
Description of drawings
Fig. 1 is a front elevational schematic of the present invention;
Fig. 2 looks synoptic diagram for a left side of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is done explanation further.
As Fig. 1, shown in Figure 2 be a kind of stretching force detecting apparatus, comprise top board 1, lower lock block 2, pair of bolts 3 and connecting screw rod 4, said top board 1 all is the square body structure with lower lock block 2.
On the upper side of lower lock block 2, be provided with the square groove that is communicated with its left and right sides face; Fixing between top board 1 and the lower lock block 2 through bolt 3; The downside of the downside of square groove and position top board 1 on it constitutes the seized fixture seal face of side up and down, and paired bolt 3 lays respectively on the relative position of both sides, square groove front and back; The width of square groove fore-and-aft direction is greater than seized fixture width 1 ~ 5mm.
Connecting screw rod 4 left ends and lower lock block 2 are fixed through helicitic texture, and right-hand member and tautness meter measuring head are fixed through helicitic texture, and its central axis is consistent with tautness meter measuring head central axis.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
