Description

Technical Field

[0001] The utility model belongs to the technical field of processing equipment and relates to a flipping and sequence transfer mechanism. Background Art

[0002] At present, there are two main forms of CNC lathe automation: one is to use joint manipulators for operation, with a square layout similar to a chessboard, and the other is to use truss manipulators for operation, with a straight line layout. In the automation form using truss manipulators, in most cases, it is necessary to flip and transport the workpiece between the previous and next processing steps.

[0003] For this purpose, a turning and transfer mechanism is arranged between lathes to realize the turning and transportation of the processed workpiece. For example, a turning and transfer mechanism disclosed in Chinese patent literature [Announcement No. CN210702594U] includes a bracket, a conveying seat and a guide rod cylinder capable of driving the conveying seat to translate in a horizontal direction are arranged on the bracket, a clamp seat, a pneumatic gripper and a rotary drive member are also arranged on the conveying seat, the gripping opening of the pneumatic gripper is arranged upward and the pneumatic gripper is fixed on the upper side of the clamp seat, and the rotary drive member can drive the clamp seat to rotate horizontally.

[0004] During operation, the above-mentioned flipping and sequence transfer mechanism can be used in conjunction with a manipulator. The workpiece of the previous process is clamped by the manipulator and transported to the pneumatic gripper, which contracts and clamps the workpiece. The guide rod cylinder drives the entire conveying seat to drive the fixture seat and the pneumatic gripper to be transported to the next process. The rotary drive member can drive the fixture seat to rotate horizontally during the conveying process or after it is transported to the right place, that is, to rotate 180 degrees in the horizontal direction to achieve the flipping of the workpiece. The manipulator of the next process can clamp the flipped workpiece and transport it to the next process for processing. However, the above-mentioned flipping and sequence transfer mechanism can only flip the workpiece left and right, but not up and down. It is still necessary to design a flipping and sequence transfer mechanism for up and down flipping. Summary of the invention

[0005] The utility model aims to solve the above problems in the prior art and proposes a turning and reversing mechanism, which solves the technical problem of how to realize the upside-down turning of the workpiece by the turning and reversing mechanism.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A flipping and sequence transfer mechanism comprises a workbench and a conveying seat, a linear slide capable of driving the conveying seat to move horizontally is fixed on the workbench, and is characterized in that a lifting cylinder located outside one end of the linear slide is also fixed on the workbench, the piston rod of the lifting cylinder faces upward and is fixed with a swing cylinder, the rotating shaft of the swing cylinder is horizontally arranged and faces the linear slide, a pneumatic gripper located above the linear slide is fixed on the rotating shaft of the swing cylinder, the fingers of the pneumatic gripper are horizontally arranged, and the conveying seat can move to directly below the fingers of the pneumatic gripper.

[0008] When the flipping and order-transferring mechanism is working, the conveying seat moves to the right below the pneumatic gripper's fingers, the pneumatic gripper's fingers open, the manipulator places the workpiece on the conveying seat and between the pneumatic gripper's fingers, the pneumatic gripper's fingers close to clamp the workpiece, then the piston rod of the lifting cylinder extends to make the workpiece leave the conveying seat, then the swing cylinder drives the pneumatic gripper to rotate 180°, the workpiece flips up and down, then the piston rod of the lifting cylinder retracts, the workpiece is placed back on the conveying seat, the pneumatic gripper's fingers open to release the workpiece, then the lifting cylinder's piston rod extends again to make the pneumatic gripper's fingers above the workpiece, then the workpiece is transported to the other end of the linear slide, waiting for the manipulator to take the workpiece away for the next process, the pneumatic gripper, lifting cylinder and swing cylinder reset to wait for the next workpiece. Therefore, the flipping and order-transferring mechanism can realize the up and down flipping of the workpiece.

[0009] In the above-mentioned flipping and switching mechanism, a fixed plate is connected between the workbench and the lifting cylinder, and the fixed plate is in an inverted L shape. The horizontal part of the fixed plate is abutted against and fixed on the upper surface of the workbench, and the cylinder body of the lifting cylinder is abutted against and fixed on the side of the vertical part of the fixed plate facing away from the workbench.

[0010] When installing the lifting cylinder, fix the cylinder body of the lifting cylinder on the vertical part of the fixing plate, and then fix the horizontal part of the fixing plate to the workbench. The setting of the fixing plate makes the lifting cylinder easy to install and stable, which is conducive to ensuring the smooth up and down flipping of the workpiece.

[0011] In the above-mentioned flipping and switching mechanism, a horizontally arranged mounting plate is fixed to the end of the piston rod of the lifting cylinder, and a connecting plate is connected between the mounting plate and the swing cylinder. The connecting plate is L-shaped, and the horizontal part of the connecting plate is abutted against and fixed on the upper surface of the mounting plate, and the cylinder body of the swing cylinder is abutted against and fixed on the side of the vertical part of the connecting plate facing away from the workbench, and the rotating shaft of the swing cylinder passes through the vertical part of the connecting plate and is fixed to the pneumatic gripper.

[0012] When installing the swing cylinder, fix the horizontal part of the connecting plate on the mounting plate, then fix the cylinder body of the swing cylinder on the vertical part of the connecting plate, and the rotating shaft of the swing cylinder passes through the vertical part of the connecting plate, fix the cylinder body of the lifting cylinder on the vertical part of the fixed plate, then fix the horizontal part of the fixed plate to the workbench, and then install the pneumatic gripper on the rotating shaft of the swing cylinder. The setting of the connecting plate makes the swing cylinder easy to install and stable, which is conducive to ensuring the smooth up and down flipping of the workpiece.

[0013] In the above-mentioned overturning and switching mechanism, the conveying seat includes a water receiving box and a material placing plate fixed in the water receiving box, and there is a gap between the surrounding of the material placing plate and the side wall of the water receiving box.

[0014] When the workpiece is processed on a lathe, coolant is often used for cooling. The workpiece is placed on a discharge plate, which separates the workpiece from the water collection box. The residual liquid on the workpiece can flow into the water collection box for temporary storage, which reduces the retention of coolant on the workpiece and prevents the coolant from dripping onto the linear slide and affecting the working stability of the linear slide.

[0015] In the above-mentioned turning and transferring mechanism, the material unloading plate is made of plastic, which can reduce the bumps and scratches on the workpieces and ensure the processing quality of the workpieces.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] Through the coordinated setting of the lifting cylinder, the swing cylinder, the pneumatic gripper and the linear slide, the workpiece can be turned upside down and transported, which is conducive to the realization of automatic turning sequence and improves the processing efficiency of the workpiece. The connection plate and the fixing plate are set to make the swing cylinder and the lifting cylinder easy to install and stable, so that the workpiece can be turned upside down smoothly.
