JE series automatic shaft straightener can be divided into C type and portal type according to the main machine structure. The main machine of C-type straightener adopts open frame structure, with simple structure, small floor space (electric control cabinet installed in the main machine), good adaptability to ultra-long (≥900mm) workpieces, and great advantages in large tonnage products. The main engine of the door straightener adopts a closed frame structure, which has the characteristics of symmetrical appearance, compact structure, good rigidity of the main engine, fast moving speed of the oil cylinder, high straightening efficiency, small moving inertia of the oil cylinder, small positioning error and easy installation on the auto production line. This structure is generally used for straightening short workpieces and levelers with small tonnage, and automatic straightening can be realized by selecting automatic loading and unloading mechanism.
The positioning and clamping parts on the worktable of C-type straightener and gantry straightener are all designed as building blocks, so as to adapt to the installation and adjustment of various movable supports, measuring units, friction drive devices and top-type rotary centers, and at the same time facilitate the maintenance and replacement of vulnerable parts, which is more conducive to users to switch and expand the straightening process of new product parts.
2. Hydraulic control system
Pump station, hydraulic valve group, actuating cylinder and hydraulic control loop constitute the hydraulic system of the leveler. The key components of the hydraulic system are products of world-renowned companies such as Japanese Oil Research Institute, Italian ATOS and Taiwan Province Northman, which ensure the accuracy, stability and reliability of the hydraulic system. When the straightener is on standby, the unique energy-saving unloading design is more suitable for the vast regional climate differences in China, which ensures that the automatic straightener can run continuously at a suitable working temperature in any region.
3. Pneumatic control unit
The pneumatic control loop consisting of pneumatic triplet, pressure relay, container valve group and actuating cylinder constitutes the pneumatic unit of the straightener. The pneumatic unit mainly controls and executes actions such as clamping, positioning, sorting and conveying of workpieces, and each executing cylinder is equipped with a position detection switch to feed back the execution of actions to the system, which is convenient for the control of action flow and the diagnosis and investigation of faults. The pneumatic components are mainly made of world-renowned companies such as Japanese SMC, German FESTO, and Taiwan Province SHAKO, with sensitive and reliable actions and long service life.
4. Workpiece radial runout detection unit
A mechanical lever measuring amplification mechanism, a high-precision displacement and angle sensor, a precision speed regulating motor and a measuring probe constitute a workpiece radial runout detection unit. The probe can be used to accurately measure the pure circular cross section, D-shaped cross section and radial runout of indexing circle of gears or splines of shaft workpieces, and there are various measuring methods, such as ultra-hard round rod measuring tappets, fully open or semi-open containing measuring sheets, high-precision standard gears and so on. The complicated and meticulous design ensures the accuracy and practicability of the measurement.
5. Programmable control center
Programmable control center is the key component of straightener. The complicated and orderly actions of the straightener are all carried out under the control of its program. PLC and computer processing system communicate with each other, and coordinate and control each executive component to perform actions such as clamping, measuring, straightening and selecting parts, pressurizing and implementing correction in an orderly manner.
6. Computer processing system
Ultra-high-precision data acquisition system, safe and reliable input and output system, industrial comprehensive workstation with large-screen color LCD display, high-professional software package, Chinese man-machine interaction interface, color graphic display and printable data statistical output constitute the computer processing system of the straightener.
