Embodiment 1

[0013] Such as figure 1 As shown, a schematic structural diagram of an automatic test equipment for scissors shear force provided in this embodiment, including a hydraulic press 8, a fixture 1 for fixing the test scissors 2, a servo motor 6 for transmitting materials for testing, and a control system 5; An oil cylinder 4 connected to the hydraulic press 8 is arranged above the fixture 1, and the output end of the oil cylinder 4 is arranged above the test scissors 2. The fixture 1 and the servo motor 6 are installed on the hydraulic press 8 . The control system 5 is provided with a liquid crystal touch screen.

[0014] When in use, lock the scissors to be tested with the clamp 1, drive the automatic feeding mechanism through the servo motor 6, automatically deliver the test nylon rod 7, and the hydraulic machine 8 drives the output end of the oil cylinder 4 to apply the force on the test scissors 2, and then through the control system The PLC program of 5 feeds back the force...

Embodiment 2

[0017] The difference from Embodiment 1 is that the output end of the oil cylinder 4 is provided with a pressure sensor 3 . When the force output by the output end of the oil cylinder 4 is applied on the test scissors 2, the magnitude of the implemented force can be detected.

Abstract

The invention discloses automatic test equipment for shearing force of a pair of scissors, which is characterized by comprising a hydraulic machine, a fixture used for fixing tested scissors, a servo motor used for conveying materials for test and a control system, wherein an oil cylinder connected with the hydraulic machine is arranged above the fixture, and the output end of the oil cylinder is arranged above the tested scissors. The invention provides the equipment which is intelligent and automatic and can accurately record the sharpness of blades, real-time shearing force, maximal shearing force and average shearing force can be displayed by a PLC program on a liquid crystal touch screen, and a curve chart can be finally formed to precisely record the actual shearing and cutting force of the blades. The automatic test equipment can carry out precision evaluation on the shearing performance of the scissors, so as to provide powerful data support for performance improvement of the blades.

Description

technical field [0001] The invention relates to an automatic test device for shearing force of scissors, in particular to an automatic intelligent test device for professional scissors shearing force for family and urban scenic spot greening, and belongs to the technical field of garden machinery and tools. Background technique [0002] In the early development process of gardening scissors, the cutting sharpness and the fatigue resistance of the blade are tested by rough simulation by manpower. It is difficult to accurately calculate and compare the cutting force of the blade, which brings certain difficulties to the design and development of the product. Contents of the invention [0003] The problem to be solved by the present invention is to provide a device that can automatically detect the shearing force of the scissors. [0004] In order to solve the above problems, the present invention provides a kind of automatic testing equipment of shearing force of scissors, i...
