Testing device for measuring end force of external rotating rod piece

Abstract

The invention relates to a testing device for measuring the end force of an external rotating rod piece. The testing device comprises a lifting unit (1), a supporting table (2) connected with the lifting unit (1), and a pressure test bench (3) supported on the supporting table (2), wherein the lifting unit (1) is used for driving the supporting table (2) to reciprocate in the vertical direction; and the pressure test bench (3) is slidably connected with the supporting table (2) and can freely slide in the horizontal direction. The lifting unit of the testing device is simple in structure and high in reliability, can be used in cooperation with other testing devices, is used for clamping and testing branch rod-shaped structures on a mechanical structure, and is convenient to use, stable in clamping and high in testing precision.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a test device for force measurement at the end of an external rotating rod. Background technique [0002] In the field of mechanical manufacturing, the workpieces produced usually need to be effectively tested for the working load of the workpiece before they are put into production. Only when the obtained test results meet the relevant requirements can they be used in large-scale production. The test items for different mechanical parts are also different, and for irregular structural parts due to the difficulty of clamping, the main body clamping test is mainly used in the test process, while for the side branch structure on the non-main body (eg, legs hinged to the main body, etc.) are difficult to test simultaneously. In view of this situation, due to the complex internal forces of the mechanical components, the test results are not comprehensive. In addition, due to the various sett...

Problems solved by technology

The test items for different mechanical parts are also different, and for irregular structural parts due to the difficulty of clamping, the main body clamping test is mainly used in the test process, while for the side branch structure on the non-main body (e.g. legs hinged to the main body, etc.) are difficult to test simultaneously

In this case, due to the complex internal force of the mechanical parts, the test results are not comprehensive

In addition, due to the various setting positions and structures of the side branch structures on the non-main body in the mechanical structure, it is also difficult to clamp them
