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 present invention is done concrete introduction.
Referring to Fig. 1 and Fig. 2, antioverloading load sensor of the present invention, comprise: the body 1 that two ends connect, the test end cap 2 and the fixing end cap 3 that are arranged at body 1 two ends respectively, be arranged at body 1 inside primary structure member 4, be arranged at body 1 sidewall and be connected the adapter 5 of exporting with signal with primary structure member 4, adapter 5 direct connection PLC etc. can export signal, deflection by primary structure member 4 draws the strength size of applied pressure or pulling force, 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 is fixedly 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 invention and testing apparatus body are installed, be provided with the mounting hole 7 that connects be used to being fixed at fixing end cap 3 away from an end of primary structure member 4, 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 certain deflection occur, 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, and test end cap 2 is equipped with the locating part that end cap 2 displacements are tested in restriction that is used for that cooperates with first step 1-1.So, after forced section 2-2 is stressed, test end cap 2 drives locating part to the direction motion of 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 from causing primary structure member 4 that irreversible distortion occurs because of overload and damaging.
As a kind of preferred, locating part is for being installed on symmetrically a plurality of caging bolts 9 of test end cap marginal position, 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 from testing, 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, in the bottom of test end cap 2 connecting hole 8 can also be set, connecting hole 8 interior formation connecting threads are used for connecting other gauge heads etc.
As a kind of preferred, fixedly end cap 3 is fixedly connected with 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 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 arranges, and then guarantees the degree of accuracy of detection.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
