It adopts the high-precision force measuring sensor from the United States, and the accuracy is controlled at <0.5% when leaving the factory. The Japanese Panasonic servo drive system and the Taiwan, CHINA TBI precision ball screw auxiliary drive ensure the displacement accuracy, reliability and stability of the equipment's up and down movement. The test speed and return speed can be preset and the position of the upper platen can be adjusted freely to complete the test automatically, making the test more convenient and effective. The sensor is located on the top and connected to the upper platen. The user or the measurement and calibration department (third party) can easily calibrate the display error of the testing machine by placing the standard sensor between the upper and lower platens for calibration.
1. Spoke sensor
2. Motor configuration
A full set of Japanese Panasonic high-performance servo drive system (including: motor + drive + reducer + coding device)
Accuracy: Realize the closed-loop control of position, speed and torque; overcome the problem of stepping motor out of step.
Speed: high-speed performance is good, generally the rated speed can reach 2000~3000 rpm.
Adaptability: strong anti-overload ability, can withstand loads three times the rated torque, especially suitable for occasions with instantaneous load fluctuations and requirements for quick start.
Stable: low-speed operation is stable, and there will be no stepping operation phenomenon similar to that of stepping motors during low-speed operation. It is suitable for occasions requiring high-speed response.
Timeliness: The dynamic response time of motor acceleration and deceleration is short, generally within tens of milliseconds. Comfort: heat and noise are significantly reduced.
3. Precision screw: Taiwan, CHINA TBI ball screw 1 pair, including transmission guide rod and beam
The transmission efficiency of the ball screw pair is as high as 90% to 98%, which is 2 to 4 times that of the sliding screw pair, and can effectively convert the torque into thrust. The transmission is sensitive and stable, the friction resistance is small, the sensitivity is good, there is no vibration when starting, no crawling at low speed, and micro-feeding can be controlled at μ level.
High positioning accuracy The temperature rise during the transmission process of the ball screw pair is small, the axial play and primary elastic deformation can be eliminated by preloading, and the screw can be pre-stretched to compensate for thermal elongation, so high positioning accuracy and Repeatability.
Good precision retention, accurate raceway shape, minimal rolling friction and wear, good precision retention, reliability and service life.
High transmission rigidity The inner and outer raceways of the ball screw pair are both eccentric corner double arc surfaces, which can be flexibly driven even when the clearance between the raceways is extremely small.
The ball screw with good synchronization performance has the characteristics of high lead accuracy and good sensitivity.
