Driven by a motor, it can precisely control the tightening torque and rotation speed of the screw, and is widely used in industrial manufacturing, assembly line production, and other fields to improve work efficiency and ensure the consistency and quality of screw tightening.

[0003] When using existing motor screw-driving devices to drive screws onto workpieces, the workpiece usually needs to be placed on a specific mold. However, during the screw-driving process, the workpiece often vibrates, affecting the accuracy of the operation and the quality of the product. To solve this problem, a limiting device is usually used to fix the workpiece. However, existing limiting devices are often bound to a specific mold. When processing workpieces of different sizes, frequent disassembly and assembly of the limiting device is not only time-consuming and labor-intensive, but may also reduce production efficiency and increase operational complexity.

[0004] To address the existing problems, there is a need to provide an adjustable motor screw-heading device that allows for adjustment of the limit device. Utility Model Content

The device also includes a mounting frame, a lead screw, guide rods, guide rings, mounting plates, sliding frames, a fixed frame, springs, a first roller, mounting rods, a lifting plate, a second roller, and an inclined plate. The mounting frame is rotatably connected to the top of the cabinet, and a lead screw is rotatably connected inside the mounting frame. Guide rods are symmetrically connected to the left and right sides of the mounting frame. Guide rings are threaded onto the lead screws, and the guide rings are slidably connected to the two guide rods. Mounting plates are evenly spaced on the electric turntable, and sliding frames are slidably connected to each mounting plate. A fixed frame is connected to the inner end of each sliding frame, and a spring connects the sliding frame to the mounting plate. A first roller is rotatably connected to each sliding frame. Multiple mounting rods are connected to the electric turntable, and a lifting plate is slidably connected to every four mounting rods.

Detailed Implementation

[0019] References to embodiments herein mean that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] Example: An adjustable motor screw heading device, such as... Figures 1-5 As shown, the system includes a cabinet 1, a screw heading machine 101, an electric turntable 2, a mounting bracket 3, a lead screw 4, a guide rod 401, a guide ring 5, a mounting plate 6, a sliding frame 7, a fixed frame 701, a spring 8, a first roller 9, a mounting rod 10, a lifting plate 11, a second roller 12, an inclined plate 13, a connecting ring 14, a cylinder 15, a push plate 16, a discharge rack 17, a baffle 18, and a sponge pad 19. The screw heading machine 101 is installed on the top of the cabinet 1, and the electric turntable 2 is also installed on the top of the cabinet 1. The groove on the 2 has a curved surface around its perimeter to facilitate workpiece ejection. A mounting bracket 3 is installed on the top of the cabinet 1. A lead screw 4 is rotatably connected inside the mounting bracket 3, allowing for height adjustment of the guide ring 5. Guide rods 401 are symmetrically connected to the left and right sides of the mounting bracket 3. Guide rings 5 ​​are threaded onto the lead screw 4 and slidably connected to the two guide rods 401. Mounting plates 6 are evenly spaced on the electric turntable 2. Sliding frames 7 are slidably connected to each mounting plate 6. A fixed frame 701 is connected to the inner end of each sliding frame 7. A spring 8 connects the sliding frame 7 to the mounting plate 6. A first roller 9 is rotatably connected to the sliding frame 7. The first roller 9 can drive the fixed frame 701 to fix the workpiece. Multiple mounting rods 10 are connected to the electric turntable 2. A lifting plate 11 is slidably connected to every four mounting rods 10. A second roller 12 is rotatably connected to each lifting plate 11. The second roller 12 can be pressed by the guide ring 5 to raise and lower. Inclined plates 13 are symmetrically connected to the bottom of each lifting plate 11. The inclined plates 13 can press the first roller 9. To move it inward, a connecting ring 14 is connected to the cabinet 1, and a cylinder 15 is installed on the connecting ring 14. A push plate 16 is connected to the telescopic end of the cylinder 15. The push plate 16 is used to push the workpiece. A discharge rack 17 is connected to the right side of the cabinet 1. The discharge rack 17 is used to discharge the workpiece. Baffles 18 are symmetrically connected to the front and rear of the discharge rack 17. A horizontal plate is connected to the outside of the baffles 18 to facilitate connection with the equipment in subsequent steps. Sponge pads 19 are connected inside the fixed frame 701 to protect the workpiece.

[0021] When this device is needed, and when clamping is required to screw a workpiece, the operator first rotates the lead screw 4. The rotation of the lead screw 4 drives the guide ring 5 to rise and fall. The operator can rotate the guide ring 5 to a suitable position according to the size of the workpiece. When the guide ring 5 moves to the suitable position, the operator stops rotating the lead screw 4. Then, the operator places the workpiece in the groove on the front side of the electric turntable 2, and then starts the electric turntable 2. The electric turntable 2 automatically rotates 90 degrees clockwise at regular intervals to ensure that each workpiece can reach the screw heading machine 101 in sequence. When the second roller 12 on the lifting plate 11 contacts the left inclined surface of the guide ring 5, it will be squeezed downwards, causing the lifting plate 11 and the inclined plate 13 to fall together. The movement of the inclined plate 13 will apply pressure to the first roller 9, causing the sliding frame 7 and the fixed frame 701 to move inwards, compressing the spring 8, thereby... The workpiece is firmly fixed. When the workpiece in the groove of the electric turntable 2 rotates to the bottom of the screw heading machine 101, the screw heading machine 101 can screw the workpiece. When the second roller 12 continues to rotate with the electric turntable 2 to the right inclined surface of the guide ring 5, the spring 8 is no longer compressed and returns to its original state, pushing the sliding frame 7, the fixed frame 701 and the second roller 12 to reset. The first roller 9 then pushes the inclined plate 13 upward, causing the lifting plate 11 to rise, completing the reset of the fixed frame 701 and releasing the clamping of the workpiece. When the workpiece in the groove of the electric turntable 2 rotates to the right side of the push plate 16, the cylinder 15 starts. The telescopic end of the cylinder 15 drives the push plate 16 to move. The push plate 16 pushes the workpiece out of the groove and onto the discharge rack 17. Then the workpiece is discharged from the discharge rack 17. The cylinder 15 automatically retracts to prepare for the next round of operation. Repeating the above operation completes the screw heading process for the workpiece.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
