[0002] With the continuous development of science and technology, in order to reduce the cost of labor, more and more production equipment are pursuing automation. Therefore, automatic screw locking machines that can greatly improve work efficiency and save costs have gradually replaced traditional manual screw tightening. However, in the process of tightening screws, traditional screw machines are prone to large vibrations and impacts due to the lack of effective shock absorption and buffering mechanisms, resulting in unstable operation and even damage to the workpiece or the machine itself. For example, a Chinese patent discloses "a fully automatic replaceable cutter head screw locking machine", and its application number is: "201720953386.7". It has an automatic cutter head changing device that can realize automatic replacement of cutter heads. There is no need to manually replace the electric screwdriver head during the production process. It has the advantages of high stability and high production efficiency. At the same time, since the cutter head can be automatically replaced, only one electric screwdriver and a variety of cutter heads are needed to be used for tightening various types of screws. There is no need to equip a corresponding electric screwdriver for each screw. It is rich in functions and greatly reduces the equipment cost. However, the device still has no shock absorption and buffering mechanism, which may cause unstable operation and inaccurate screw positioning. Utility Model Content

[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1-4The embodiment of the utility model is a fully automatic screw locking machine with replaceable blades, which includes: a workbench 2, which is used as the basic support platform of the entire machine. The upper top wall of the workbench 2 is fixedly connected with a damper 14, which is used to absorb and reduce the vibration and impact generated by the machine during the screw tightening process. The upper top wall of the workbench 2 is fixedly connected with a buffer spring 15, which is used to cooperate with the damper 14 to further enhance the shock absorption effect. The damper 14 is located at the center of the buffer spring 15, and the workbench 2 covers the damper 14 and the buffer spring 15. The lower ends of the damper 14 and the buffer spring 15 are fixedly connected with a bottom shell 1, which is used to provide support for the damper 14 and the buffer spring 15, and to close the bottom of the machine to maintain the integrity of the machine structure. The upper surface of the workbench 2 is fixedly connected with a bracket 3, which is used to support the guide plate 4 to ensure the stability and verticality of the guide plate 4.

[0024] The upper surface of the bracket 3 is fixedly connected with a guide rail plate 4 for providing a sliding track for the mobile plate 7. The front and rear surfaces of the guide rail plate 4 are provided with a limiting groove 16 for limiting the sliding path of the mobile plate 7. The left surface of the guide rail plate 4 is fixedly connected with a motor 5 for providing power for the screw rod 6 to drive the screw rod 6 to rotate. The output end of the motor 5 is fixedly connected with the screw rod 6 for driving the mobile plate 7 to move along the guide rail plate 4. The screw rod 6 passes through the left surface of the guide rail plate 4 and extends to the right inner wall of the guide rail plate 4. The right inner wall of the guide rail plate 4 is provided with a positioning groove for preventing the screw rod 6 from deflecting. The end of the screw rod 6 away from the motor 5 is located inside the positioning groove. The side surface of the screw rod 6 is movably connected with the mobile plate 7 for connecting and installing a protective shell 8. The protrusion 10 provided on the mobile plate 7 is located inside the limiting groove 16 for ensuring the stability of the mobile plate 7. The front end of the mobile plate 7 is fixedly connected with a protective shell 8 for providing protection for the electric telescopic rod 13 to prevent external interference and damage.

[0025] The upper top wall of the protective shell 8 is fixedly connected to an electric telescopic rod 13. The protective shell 8 is located directly in front of the guide plate 4 and is used to adjust the height of the electric screwdriver 9 so that the cutter head 12 can be accurately aligned with the screw hole. The electric telescopic rod 13 passes through the lower surface of the protective shell 8. The lower end of the electric telescopic rod 13 is fixedly connected to the electric screwdriver 9 for rotating and pressing down the cutter head 12. The electric screwdriver 9 is located directly below the protective shell 8. The lower surface of the electric screwdriver 9 is rotatably connected to a rotating box 11 for replacing different cutter heads 12. The lower surface of the rotating box 11 is rotatably connected to multiple cutter heads 12, which are the components that actually come into contact with the screws.

[0026] Working principle: The motor 5 acts as a power source to drive the screw rod 6 to rotate. The screw rod 6 is connected to the movable plate 7 by a threaded connection. Therefore, when the screw rod 6 rotates, it will drive the movable plate 7 to move horizontally along the limit groove 16 on the guide plate 4, so that the movable plate 7 can be accurately moved to the specified position to prepare for the subsequent locking operation. After the movable plate 7 reaches the specified position, the electric telescopic rod 13 starts working to adjust the height of the electric screwdriver 9. By extending or shortening the telescopic rod, it ensures that the cutter head 12 of the electric screwdriver 9 can be accurately aligned with the screw hole, providing precise positioning for the locking operation. In this process, the screw is transported to the vicinity of the electric screwdriver 9 through a certain feeding system (usually including a vibrating plate, a silo, etc.). When the cutter head 12 is aligned with the screw hole, the electric screwdriver 9 starts, and the motor inside it drives the cutter head 12 to rotate and press down to screw the screw into the screw hole. The electric screwdriver 9 usually has a torque control function, which can ensure that the screw stops automatically after reaching the predetermined locking torque. The cutter head 12 is rotatably connected to the lower surface of the electric screwdriver 9 through the rotating box 11 for real-time replacement.

[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
