Description

Technical Field

[0001] The utility model relates to the field of screw loading and unloading equipment, in particular to a new type of screw loading and unloading machine. Background Art

[0002] In the current intelligent assembly industry, in the transformer coil pressing section, the coil tooling assembly adopts screw connection, the air claw of the loading and unloading machine clamps the screw and sends it into the tooling, and then the tightening gun locks the nut. In the process of tightening the gun, the screw moves up to drive the air claw to be subjected to force. In the transformer coil disassembly and assembly section, when the screw is fed, the nut will loosen, causing the center position of the screw to run away or tilt. When the air claw is pushed out to clamp the screw, it cannot clamp the screw in the center. The existing loading and unloading machines mainly solve the problems of loading and unloading accuracy and stable equipment operation.

[0003] The above loading and unloading cannot meet the production requirements. Therefore, a new type of screw loading and unloading machine is urgently needed to solve the problems of equipment damage, inaccurate loading and unloading, and affecting the normal operation of the equipment.

[0007] Through the above technical solution, the guide rod moves on the main frame to provide a limiting force for the vertical movement of the lifting plate, thereby preventing the lifting plate from shaking left and right during the lifting process.

[0008] Furthermore, a transplanting plate is fixed to one end of the transplanting cylinder, a second linear guide is fixedly mounted on the transplanting plate, an air claw is movably mounted on the second linear guide, and a clamping block is movably mounted on the air claw.

[0010] Furthermore, a limit plate is fixedly installed on the air claw, the limit plate cooperates with the clamping block, and a fixing plate is installed at the bottom of the lifting plate, and the fixing plate is fixedly installed on the main frame.

[0011] Through the above technical solution, the limiting plate is fixed on the top of the clamping block, and the object clamped in the clamping block is limited and supported through one end of the limiting plate.

[0012] Furthermore, a positioning plate is fixedly mounted on the fixing plate, a proximity switch is fixedly mounted on the positioning plate, and a dead baffle is fixedly mounted on the transplanting plate.

A top screw hole is punched on the air claw clamping block, and the top screw is used to limit the rotation of the screw. A limit plate is added to limit the screw to the center position of the air claw, which makes it convenient for the air claw to clamp the screw in the center, thereby ensuring accurate loading and unloading.

[0027] The implementation principle of a new type of screw loading and unloading machine in the embodiment of the present application is:

[0028] The lifting cylinder 2 is extended and the transplanting mechanism is lifted up. The transplanting mechanism includes the transplanting cylinder 7 and the transplanting plate 8. The robot puts the screw on the positioning plate 12. The proximity switch 16 detects that it is in place. The clamping block 10 on the air gripper 9 clamps the screw. The clamping block 10 lifts up to limit the rotation of the screw. The positioning plate 12 on the air gripper 9 limits the inclination of the screw. The transplanting cylinder 7 is extended and the screw is pushed into the tooling. The tightening gun rotates and the locking nut is tightened. The screw moves up due to the upward pulling force. The air gripper 9 slides along the slider on the second linear guide 13. The air gripper 9 is not subjected to force and the locking is completed. The air gripper 9 opens and the transplanting cylinder 7 retracts. Under the action of the buffer 14, the dead baffle 15 is pushed down, thereby restoring the clamping components such as the air gripper 9 to their original positions. Then the lifting cylinder 2 is retracted and the loading and unloading machine returns to its initial position.
