Product features of electric rotary table
1. The rotating shaft system is precisely processed by multi-channel technology, with high matching accuracy, large bearing capacity and long service life.
2. The design of precise worm gear transmission and shaft system has the advantages of high adjustment accuracy, small air return and adjustable air return clearance caused by the use of the structure of eliminating air return.
3. The end jump and eccentricity of the rotary table are low, and the rotary movement is stable.
4. The center through-hole and the center of rotation of the rotary table are strictly coaxial, and the center hole diameter is strictly matched with the tolerance limit, which is convenient for precise positioning.
5. The inlet motor and worm are connected by imported high-quality elastic coupling, the transmission is synchronous, the deviation elimination performance is good, and the empty return and the form and position error are eliminated.
6. Provide electrical accessories of stepping and servo, provide relevant technical support, accept product reform and customization.
What are the characteristics of electric control rotary table
1. Standard step motor and RS232 interface, through the company's motion controller to achieve automatic control.
2. The rotating shaft system is precisely processed by multi-channel technology, with high matching accuracy, large bearing capacity and long service life.
3. It adopts the worm gear and worm structure with precise research, which is comfortable in movement, can rotate in any direction and reverse direction, and has small space return.
4. It can adjust the gap of air return caused by long-term use.
5. The special structure design ensures the low end jump and eccentricity of the rotary table and makes the rotary movement more stable.
6. The scale ring on the periphery of the table is a laser scribed scale, which can rotate relative to the table for the convenience of initial positioning and reading.
7. Step motor and worm are connected by imported high-quality elastic coupling, the transmission is synchronous, the performance of depolarization is good, and the eccentric disturbance is greatly reduced and the noise is small.
8. The electric rotary table can be used either horizontally or vertically, and can be combined with other types of tables to form a multi-dimensional electric adjustment table
9. Limit function can be added, initial zero position can be added, servo motor can be replaced, rotary encoder can be added, and product reform and customization can be accepted.
Common features of rotary table products
1. The rotating motion of the motor can be quantitatively transformed into linear motion by the electric rotating table, and its energy conversion efficiency can reach 70% (ball screw).
2. The precision electric indexing table has high movement precision. Positioning accuracy and repeated positioning accuracy can reach micron level. For example, if the drive motor is a stepping motor, the pitch angle of the motor is 1.8 °. The pitch of the drive screw is 4 mm. The motor will rotate 200 turns. The linear displacement reflected on the translation table is the screw pitch of the lead screw. It's 4mm. Then the motor moves step by step. The linear displacement of the electric translation table is 4 / 200 = 0.02mm. In addition, the stepping motor driver also has pulse subdivision function. Every action of the motor can be subdivided. If 8 subdivisions are used, each action of the motor. The linear displacement of the electric rotary table can reach submicron level theoretically.
3. Different types of motion conversion can be used to achieve high-speed motion. In many applications, it is necessary to improve the speed of the electric rotary table. In this case, there is usually such a form of mobile rotary table. The driver is a high-speed servo motor. The transmission is a large pitch screw or rack and pinion drive, toothed belt, etc. This does not affect accuracy and fluency. Under this premise, the speed of motion is increased.4. When the mobile rotating platform is used in combination, the tools installed on it can reach any point in 3D space. The complex trajectory can be achieved by linear interpolation control.
