Sort
Temperature control turntable according to the number of axes is divided into: single-axis temperature control turntable, two-axis temperature control turntable, three-axis temperature control turntable
Turntable maintenance
Single axis turntable, double axis turntable, three axis turntable are applicable.
Maintenance of the three-axis turntable machine body
When using the turntable, the shafting should be avoided by the impact force. Before installing the load, scrub the installation surface and the contact surface between the load and the installation surface.
If not used for a long time, the installation surface should be scrubbed clean and then evenly coated with a layer of anti-rust oil. In the period of high ambient air humidity, it is necessary to often open dehumidification equipment, such as dehumidifier, air conditioner, etc.
The non-painted surface of the table body that is in contact with sweat when using the table body should be wiped frequently. When using organic solvents in countertop operation, be careful not to damage the paint surface of the countertop body.
Maintenance of three-axis turntable chassis
The power cables and signal cables of the measuring chassis must be routed safely and reliably to avoid short circuit, open circuit, or poor contact caused by external forces.
When moving the measuring chassis, handle it gently to avoid impact and bump.
If the circuit of the measuring chassis is faulty, check the contact status of the signal cable, power cable, and ground cable first, and then check the digital display table according to the wiring table.
The single-axis position rate turntable is composed of two parts: mechanical table body and measurement and control system (temperature control box can be installed). The table body adopts precision mechanical shafting, which has the functions of position, speed and low-frequency sinusoidal swaying motion. It mainly provides the positioning and speed reference for the load to be measured, and is used for static testing and calibration of inertial element components and inertial navigation systems.
Single-axis temperature control position rate turntable adds temperature control environment box to provide high and low temperature test environment for the measured load. Other technical indicators can refer to the single-axis position rate turntable.
Inertial navigation test turntable according to the needs, there are electric and manual two driving modes, according to the structure can be divided into single axis, two axis and three axis turntable, with position, speed, swing, tracking and other functions, used for a variety of inertial devices, inertia combination, tracking devices and other ground testing.
The inertial navigation test turntable is composed of a mechanical platform and a measurement and control system. The mechanical platform structure is usually frame type and table type according to the need, supported by precision angular contact ball bearings, driven by torque motor, equipped with optical code disc, circular induction synchronizer and other Angle measuring elements, but also equipped with speed measuring machine, photoelectric sensors and other devices. The measurement and control system is composed of Angle measuring unit, servo control unit and upper control computer. The Angle measuring accuracy can reach 3 arc seconds, and the speed accuracy can reach more than 4×10E-5.
The two-axis rotary table test is composed of two parts: mechanical table body and measurement and control system. The table body adopts U-T structure form and precision mechanical shafting. It has position, speed and low frequency sinusoidal swaying motion functions, which can provide accurate uniaxial and biaxial positioning and speed reference for the measured load, and is used for static testing and calibration of inertial element components and inertial navigation system. The machine body has two degrees of freedom of motion, azimuth (X) axis and pitch (Y) axis. It is a countertop type two-dimensional precision testing equipment.
The simulation of the three-axis turntable is composed of two parts: the mechanical body and the measurement and control system. The body adopts the U-O-O structure (the inner frame is the circular barrel structure), the precision mechanical shafting and the high stiffness platform structure. It mainly has the functions of simulation, position, speed, swing, etc., which can simulate the three-dimensional movement of the carrier, and is used in the ground hemiphysical simulation system to provide close to the real movement environment for the warhead and the guidance load. It can also provide single axis, two axis or three axis positioning and speed reference for the load under test, for the inertial element components, inertial navigation system testing and testing.
Repair, maintenance and precautions are as follows
1) After turning on the turntable power supply, wait 5 seconds before continuing the following operations;
2) Strictly operate in the order of startup and shutdown;
3) The turntable is powered at least once a month;
4) Test after starting and preheating for half an hour;
5) After the "power" switch is turned on, if the digital tube display is abnormal (there are more than two digits jump), the "power" switch should be turned off and restarted. If it is still abnormal, report for repair;
6) After the system is put into operation, if the turntable oscillates, the "enable" switch and "power" switch of the control system must be removed as soon as possible to check the cause.
7) The turntable corresponds to the control chassis one by one and cannot be mixed.
8) The turntable should be wiped clean before and after use to avoid hard objects hitting, scratching, contact with chemical solvents;
9) The installation load should be handled lightly to avoid damaging the installation surface;
10) When loading is installed, the locking device of shafting can be locked to eliminate the inconvenience caused by shafting rotation;
11) When the turntable is working, the locking device of the shafting must be in a loose state (described in the operation);
12) When using the turntable, the load mounting surface should be avoided from being scratched or bruised by harder objects. Before load installation, scrub the contact surface between load and installation surface with absorbent cotton soaked in gasoline;
13) The installation surface must be clean and must not bump or scratch with hard objects. If not used for a long time, the installation surface should be scrubbed clean, and then evenly coated with a layer of anti-rust oil. In the period of high ambient air humidity, it is necessary to often open dehumidifier equipment, such as dehumidifier and air conditioner.
14) When using the platform body, the unpainted surface of the platform in contact with sweat stains should be wiped frequently. When using organic solvents in countertop operation, be careful not to damage the surface finish of the counter top body.
