The rotating plate is installed on the pneumatic rotary table, and the discharging support plate is fixed at both ends of the rotating plate. The bar is placed in the support groove of the discharging support plate. When reversing is needed, the pneumatic rotary table receives the control signal and drives the rotating plate to rotate 180° or other set angles, thereby realizing the reversing of the bar.

[0024] Mechanical hand type reversing device: uses the clamping and rotating functions of the mechanical hand to realize the reversing of the bar. Generally composed of mechanical arm, clamping jaw and rotating drive mechanism. The mechanical arm can move in three-dimensional space to grab the bar from one position and move it to the designated reversing position. The clamping jaw is used to clamp the bar, and the rotating drive mechanism drives the clamping jaw and the bar to rotate to achieve the reversing purpose.

[0025] Chain transmission type reversing device: mainly composed of chain, sprocket, motor and clamp, etc. The motor drives the sprocket to rotate, and the sprocket drives the chain to move. The chain is installed with a clamp for fixing the bar. By controlling the forward and reverse rotation of the motor, the chain drives the bar to move to different positions, while cooperating with specific guide mechanisms and overturning mechanisms to realize the reversing of the bar in different stations.

[0029] Execution part: Directly acts on the bar stock, realizing clamping, loosening and reversing operations, such as clamping jaws, rotating discs, and turnover mechanisms, etc.

[0030] Control part: Usually composed of controllers, sensors, etc., used to control the start-stop, speed, direction, etc. of the power-driven part, as well as monitor the running state of the device, ensuring accurate reversing of the bar stock.

[0031] Application scenarios

[0032] Lathe processing: When turning the ends of short bar stock, using an automatic reversing device can automatically reverse the bar stock after processing one end, so as to process the other end, improving processing efficiency and accuracy, and reducing manual operation.

[0033] Milling machine processing: For cases where milling operations need to be performed on different sides of the bar stock, the automatic reversing device can accurately rotate the bar stock to the required angle, realizing multi-surface processing and ensuring processing quality and consistency.

[0034] Drilling machine processing: When drilling holes at both ends or different positions of the bar stock, the automatic reversing device can quickly and accurately position the bar stock to the appropriate position, facilitating drilling operations and improving drilling accuracy and efficiency.

[0035] Advantages

[0036] Improved production efficiency: No need for manual bar stock reversing, reducing the time for loading and unloading and reversing, enabling continuous automated production and improving processing efficiency.

[0037] Reduced labor intensity: Avoids repetitive labor such as bar stock handling and reversing, reducing labor intensity and improving working environment.
