Slope rill erosion measurer

The invention discloses a slope rill erosion measurer which is characterized in that a transverse beam which can slide up and down is connected with a metal framework; one end of a measuring needle is provided with a screw cap, and the other end of the measuring needle passes through the transverse beam and then extends out of the framework; the upper end of the framework is provided with a level instrument and a transverse scale, and the lower end of the framework is connected with two fixed borers which can be inserted into a slope; one side of the framework is provided with a vertical scale and an angle gauge, and the other side of the framework is connected with two positioning bolts; and the slope rill erosion measurer can be connected with another measurer in parallel for use. When the measurer is vertically inserted into the slope, the measuring needle is used for measuring the amount of rill erosion of soil of the slope, and the angle gauge is used for measuring the gradient of the slope. The slope rill erosion measurer is suitable for measuring the amount of slope rill erosion in field soil, has the advantages of simple operation and convenient carrying, and can be assembled and disassembled on the spot; a digital photographic technology can be used for quickly recording the measured data, thereby improving the measuring accuracy; and the data processing at the later stage is relatively simple.

Six-axis industrial robot track accurate tracking-and-controlling oriented intelligent teaching system

InactiveCN106647529ARealize flexible interactionRealize the Internet of ThingsProgramme controlComputer controlControl orientedIndustrial Ethernet
A six-axis industrial robot track accurate tracking-and-controlling oriented intelligent teaching system belongs to the technical field of robots. When a six-axis robot teaching box is operated for teaching, a robot end can be directly drawn so that a robot arrives at a preset position along with a drawing force. In a drawing process, direction of the drawing force which is applied to the robot end can be automatically calculated and predicated, and a six-axis robot end automatically performs pose adjustment. Not only are smoother dragging track and higher control precision realized, but also shorter time in a teaching process is obtained. A six-axis force sensor senses an instruction which is input into the sensor by an operator so that a six-axis industrial robot controller automatically records the current position, and furthermore along with instruction change, the six-axis industrial robot controller is automatically switched to a grabbing function, thereby realizing simple operation. In communication, data exchange is performed based on industrial Ethernet. An embedded system is introduced for processing data. Therefore the six-axis industrial robot track accurate tracking-and-controlling oriented intelligent teaching system has advantages of short response time, high practicability, high transplantability, high application value, etc.

Static balance test method applied to gyroscope position marker spindle

The invention discloses a static balance test method applied to a gyroscope position marker spindle. A horizontal axis angular position rotary table is used for mounting and clamping a gyroscope position marker to be tested, any one axis to be tested of the gyroscope position marker is parallel to the horizontal axis of the rotary table by adjusting direction of a mounting fixture, a measurement and control system drives the tested axis to complete sine small angle vibration at each locking angular position of the rotary table, value of a static unbalance can be solved by virtue of integration on measured quantities in a driving current period of the tested axis, and position of the static unbalance can be obtained by observing the driving current and an angular position signal and combining a corner of the horizontal rotary table. The concrete test process comprises the following steps of: step one, measuring torque constant of the tested axis; step two, carrying out static balance test on the gyroscope position marker spindle; and step three, selecting the rest test axes of the gyroscope position marker and carrying out test, after the tested axis is determined, repeating the step one and the step two, and finally completing test on three tested axes, namely an outer annular axis, a middle annular axis and an inner annular axis, thus the test method disclosed by the invention is finished.
