Description

TECHNICAL FIELD

[0001] The present application belongs to the field of straightening machine device, and particularly relates to a feeding and discharging device of a straightening machine. BACKGROUND

[0002] Shaft parts are typical parts often encountered in hardware fittings, which are mainly used to support transmission parts, transmit torque and bear load. They are used to support transmission parts such as gears and pulleys in machines to transmit torque or motion. Shaft parts are rotating body parts, and poor straightness will lead to bending deformation during installation and use, affecting mechanical transmission accuracy, producing vibration and noise, especially in the automotive industry. Therefore, workpiece straightening has become one of the processes of shaft parts, and the straightening machine is particularly important.

[0003] The straightening machine is a device for straightening various shaft parts in the automotive and other mechanical industries that have been deformed during heat treatment. The top center of the driving and driven rotary centers clamps the workpiece, and the top center is driven to rotate by the speed regulating motor. The measurement device connected to the movable support detects the total runout of the workpiece surface. The computer judges the maximum bending position and direction of the workpiece according to these data, and sends instructions to stop the workpiece rotation when the maximum bending point is upward. Combined with the set parameters, the computer calculates the correction amount to achieve accurate correction of the workpiece. In recent years, most straightening machines use manual feeding and discharging. Due to the fast running speed of the straightening machine and the diversification of shaft part diameters and lengths, it is difficult to ensure the straightening position of the shaft parts, so manual operation is still needed to ensure the position of the shaft workpiece.

[0004] The specific operation method of manual feeding and discharging of the prior art straightening machine is to manually take the shaft workpiece from the tray and put it into the straightening tool. After manual positioning, the straightening machine bed is manually started for straightening. After the straightening is completed, the workpiece is taken out after the bed is completely reset. This feeding method has the disadvantages of high labor intensity, low production efficiency, and the diversification of shaft part diameters and lengths, which makes it difficult to ensure the straightening position of the shaft parts. In addition, the fast running of the straightening machine poses a great safety hazard. SUMMARY
