Description

Technical Field

[0001] The utility model relates to a tooling for quickly detecting the force value of a semi-finished stay bar. Background Art

[0002] The customer of the stay bar assembly has requirements for the standard force value range. Before assembling the stay bar assembly, it is necessary to verify the force value range of the semi-finished stay bar (motor + lead screw + damper).

[0003] In the prior art, a tensile testing machine is used to measure the force value range. However, in the prior art, the semi-finished stay bar is fixed to the tensile testing machine by simple wire ties, which is relatively unreliable.

[0004] Therefore, how to connect the semi-finished stay bar to the tensile testing machine is a technical problem to be solved.

[0005] Based on the above problems, we have designed a tooling for quickly detecting the force value of a semi-finished stay bar, which can effectively clamp the semi-finished stay bar and facilitate tensile testing. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a tooling for quickly detecting the force value of a semi-finished stay bar, which can effectively clamp the semi-finished stay bar and facilitate tensile testing.

[0007] To solve the above problems, the utility model adopts the following technical solutions:

[0008] A tooling for quickly detecting the force value of a semi-finished stay bar includes a pressing assembly and a connecting assembly. The stay bar to be tested is loaded between the pressing assembly and the connecting assembly. The pressing assembly is fixedly connected to the upper crossbeam of the tensile testing machine by a pin, and the connecting assembly is fixedly connected to the sensor end of the tensile testing machine by a pin.

[0009] Preferably, the pressing assembly includes a pressing cover and a fixing plate. The stay bar to be tested is clamped between the pressing cover and the fixing plate. The lead screw nut assembly and the thick aluminum conduit assembly of the stay bar extend outside the fixing plate, and the thick aluminum conduit assembly is connected to the connecting assembly. A sleeve for positioning the lead screw nut assembly is provided at the end of the fixing plate away from the pressing cover.

[0010] Preferably, the pressing cover and the fixing plate are fixed by screws.

[0011] Preferably, a threaded hole is provided at the center of the end of the pressing cover away from the fixing plate. A first fixing rod is assembled through the threaded hole. After the first fixing rod is screwed into the threaded hole, it abuts against the stay bar to be detected. A first connection end is provided at the end of the first fixing rod away from the pressing cover, and a first pin hole for matching the pin of the upper crossbeam of the tensile testing machine is penetrated through the outer wall of the first connection end.

[0012] Preferably, a locknut is fitted on the first fixing rod. When the first fixing rod is screwed into the threaded hole and abuts against the strut to be detected, the locknut is screwed to be tightly attached to the press-fitting cover.

[0013] Preferably, the connecting assembly includes a connecting nut and a second fixing rod fitted at one end of the connecting nut. The second fixing rod has a second connecting end, and a second pin hole for fitting the end pin of the tensile testing machine sensor penetrates through the outer wall of the second connecting end. A connecting rod is screwed into the end of the connecting nut away from the second fixing rod. The connecting rod is inserted into the thick aluminum conduit assembly, and a safety pin is fitted between the connecting rod and the thick aluminum conduit assembly.

[0014] The beneficial effects of the present utility model are as follows:
