The implication of Reference numeral among the figure: 1, body, 2, the test end cap, 3, fixing end cap, 4, primary structure member, 5, adapter, 6, screw, 7, mounting hole, 8, connecting hole, 9, caging bolt, 1-1, first step, 1-2, second step, 2-1, installation portion, 2-2, forced section.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Referring to Fig. 1 and Fig. 2, antioverloading load sensor of the present utility model, comprise: the body 1 that two ends connect, respectively be arranged at the test end cap 2 at body 1 two ends and fixing end cap 3, be arranged at body 1 inside primary structure member 4, be arranged at body 1 sidewall and be connected the adapter of exporting with signal 5 with primary structure member 4, adapter 5 direct connection PLC etc. can export signal, draw the strength size of applied pressure or pulling force by the deflection of primary structure member 4, thus the stress performance of test products.
In order to realize test function, test end cap 2 is connected with an end of primary structure member 4 and can produces displacement with respect to body 1; Fixedly end cap 3 is connected with the other end of primary structure member 4 and fixedlys connected with body 1, and connected mode can be interference fit or be threaded, as long as guarantee to connect reliable.
Simultaneously, for antioverloading load sensor of the present utility model and testing apparatus body are installed, be provided with away from an end of primary structure member 4 at fixing end cap 3 and be used to the mounting hole 7 that is fixed and connects, in mounting hole 7, be formed with the installation screw thread, thus it is reliably fixing easily.
Specifically, that test end cap 2 is connected with primary structure member 4 is installation portion 2-1, towards body 1 outside is forced section 2-2, in the test process, the stressed primary structure member 4 that is passed to again of forced section 2-2, make primary structure member 4 that the certain deformation amount take place, thereby feedback result obtain the size of applied pressure or pulling force.
Further, stressed excessive and cause the antioverloading load sensor impaired in order to prevent, body 1 is formed with first step 1-1, test end cap 2 be equipped with cooperates with first step 1-1 be used to limit the locating part of testing end cap 2 displacements.So, after forced section 2-2 is stressed, test end cap 2 drives the direction motion of locating part to first step 1-1, when locating part props up first step 1-1, the displacement of test end cap 2 has reached maximum, the stressed of primary structure member 4 reaches capacity, and effectively prevents to cause primary structure member 4 that irreversible distortion takes place because of overload and damage.
As a kind of preferred, locating part is for being installed on a plurality of caging bolts 9 of test end cap marginal position symmetrically, caging bolt 9 adopts with test end cap 2 and is threaded, before the test beginning, at first adjust the gap length between caging bolt 9 and the first step 1-1, guarantee that primary structure member 4 can not transship, and guarantees the serviceable life of product when caging bolt 9 props up first step 1-1.In the practical operation, caging bolt 9 is moved in order to prevent to test, and after the gap length between caging bolt 9 and the first step 1-1 is determined, at the position employing anaerobic adhesive that caging bolt 9 is connected with test end cap 2 both is fixed more reliably.
In addition, a connecting hole 8 can also be set, form connecting thread in the connecting hole 8, be used to connect other gauge heads etc. in the bottom of test end cap 2.
As a kind of preferred, fixedly end cap 3 is fixedlyed connected by some screws 6 with body 1.In the present embodiment, screw 6 is 4, is uniformly distributed in a week of body 1 sidewall.
As a kind of concrete structure, body 1 is a cylindrical shape.
Further, referring to Fig. 3, as a kind of improvement, body 1 also is formed with second step 1-2, and fixedly end cap 3 is installed on second step 1-2 and is close to inwall; The effect of second step 1-2 is to guarantee that fixing end cap 3 vertically is installed on the top of body 1, guarantees that primary structure member 4 vertically is provided with, and then guarantees the degree of accuracy of detection.
More than show and described ultimate principle of the present utility model, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the utility model in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in the protection domain of the present utility model.
