The linear sliding table consists of a driving motor, a reduction gear, a screw, a nut, a guide sleeve, a push rod, a sliding seat, a spring, a shell, a turbine, a micro control switch and the like. Linear slide table is a new type of electric actuator, which is mainly composed of motor, push rod and control device, and can realize remote control and centralized control. The linear sliding table moves back and forth within a certain range of travel. Generally, the standard travel of the linear sliding table is 100, 150, 200, 250, 300, 350 and 400mm, and the special travel can also be designed and customized according to the requirements of different application conditions.
The linear slide table can be designed with different thrust according to different application loads, generally, the thrust can reach 6000N, and the no-load running speed is 4 mm ~ 35 mm/s. The linear slide table takes a 24V/12V DC permanent magnet motor as the power source, which converts the rotation motion of the motor into linear reciprocating motion. Push a group of linkage mechanisms to complete the switching of air doors, valves, gates and baffles.
Using the linear sliding table as the actuator can not only reduce the air supply device and auxiliary equipment required for using the pneumatic actuator, but also reduce the weight of the actuator. Pneumatic actuators need to have a certain air pressure in the whole control operation process. Although amplifiers with low consumption can be used, the air consumption is still very large over time. When the linear sliding table actuator is used, power supply is needed when the control opening is changed, and it can be stopped when the required opening is reached. Therefore, Kgg linear sliding table actuator has the advantage of energy saving compared with pneumatic actuator.
It is suitable for long-distance use and is used for opening and closing, material loading and unloading, flow control and other mechanisms of dampers, valves and gates in electric power, chemical industry, metallurgy, mining, light industry, transportation, ships and other departments. Now it has been used by more and more departments to replace the automatic device of mechanical hand, hydraulic valve and deceleration transmission mechanism.
After the motor is decelerated by the gear, it drives a pair of screw nuts. Turn the rotary motion of the motor into linear motion, and use the forward and reverse rotation of the motor to complete the push rod action. For example, through various mechanisms such as levers, rockers or connecting rods, complex actions such as rotation and shaking can be completed.
By changing the length of the lever arm, the stroke can be increased or decreased. Travel control device. Worm gear and worm transmission form: the worm on the motor gear drives the worm wheel to rotate, so that the small screw in the worm wheel moves axially, and the connecting plate drives the limit rod to move axially accordingly. When the required stroke is reached, the motor stops running by adjusting the limit block to press the stroke switch (the positive and negative control are the same). Gear transmission form: the motor drives the small screw installed in the inner tube after passing through the reduction gear, and drives the nut connected with it to run axially. When the set stroke is reached, the nut antenna presses the limit switch to cut off the power supply, and the motor stops moving (the reverse direction is the same).
A potentiometer can be selected to display the stroke state of the push rod, and an encoder can be added to realize the complete stroke in several steps (that is, stop and go). The Kgg linear transmission device, linear sliding table, DDA spline and other series products of Shanghai Dizi are novel and exquisite in design, small in size, high in precision, synchronous, good in self-locking performance and sanitary, and directly driven by motor, and do not need gas source and oil circuit of pipelines. Now they have been widely used in production lines, automobiles, ventilation window opening, stage, textile, sewage treatment and other industries and equipment.
