The test lab set-up includes a test flow bench for mounting one or more test devices, an adjustable nozzle for simulating urine flow, and a sensor for collecting data associated with the simulated urine flowing through the test device(s). A computing device for measuring and/or calculating various parameters associated with the simulated urine flow may also be included. The test device may have a shape corresponding to a handheld uroflowmeter subject to testing. The angle of the adjustable nozzle may be adjusted to test for various angles of urine flow. Similarly, the angle, pitch, and roll of the test device may be adjusted to test for various angles at which a uroflowmeter is held. As fluid flows through the test device, the sensor collects information such as, for example, flow rate, duration, volume, and the like. The sensor transmits the data collected to a computing device for additional processing.

The present invention discloses an machining device based on a portable 5-DOF parallel module. The machining device based on a portable 5-DOF parallel module comprises: a table for moving a parallel module to increase the stroke of the machine tool such that the machine tool can machine large components and can also simultaneously conduct the mounting and the machining of workpieces at different stations; a CNC rotary table; and a portable 5-DOF parallel module. The portable parallel module has a large swing angle range, can conduct the conversion between vertical and horizontal machining modes and can achieve five-face machining in one setup in cooperation with the CNC rotary table. The parallel module can move flexibly, and can machine large and complex components after mounted on the sliding table. After the machining of the workpiece is completed, the parallel module can move to the position of a mounted component through the table to conduct the machining of the next component. Thus, the mounting and the machining of the workpiece are simultaneously conducted at different stations, and the utilization rate and the production efficiency of the portable parallel module are improved.

A machine tool includes a Z-slider with a main spindle rotating about a spindle axis, a main body on which the Z-slide is arranged, a machining table with a machining plane, a clamping device for clamping a workpiece, and a first drive to rotate the clamping device about an rotational axis. A support member is arranged on a pivot-axis housing on which the machining table is arranged. A second drive pivots the support member and the machining table about a pivot axis. The support member has first and second legs. The machining table is arranged on the first leg such that the support member and the housing form a U-shaped unit and provide an interspace between the second leg and the housing, into which interspace a toric workpiece clamped on the clamping device can project and is rotatable about the axis of rotation by the first drive.

A 6-axis positioning system includes a base, a movable unit and six variable-length actuators. One end of each actuator is connected to the base, and the other end of each actuator is connected to the movable unit. The six actuators are divided into two groups each having three actuators.
