Description
Technical Field
[0001] The utility model relates to the technical field of automatic screw locking machines, in particular to a clamping head structure of an automatic screw locking machine. Background Technique
[0002] In manufacturing industries such as electronics and machinery, the fastening of screws is a common and important task. With the development of automation technology, automatic screw locking machines are widely used in production lines to improve production efficiency and the quality of screw locking. Among them, the clamping head structure is one of the key components of the automatic screw locking machine, and its performance directly affects the clamping and locking effects of screws.
[0003] When the clamping head structure of a conventional automatic screw locking machine in the prior art is in use, when it is necessary to process screws of different specifications or types, if the screwdriver cannot be quickly disassembled and replaced, the operator needs to spend a lot of time manually disassembling and installing the screwdriver, or the entire clamping head structure or even the automatic screw locking machine needs to be replaced. The inability to quickly replace the screwdriver means that there is a long conversion time between different screw installation tasks and continuous production cannot be achieved; therefore, we propose a clamping head structure of an automatic screw locking machine to solve this problem.

The disassembly component 9 includes: a cylinder 904, a circular frame 905 and a cross plate 901. The cylinder 904 is slidably mounted in the circular frame 905. Two groups of limiting rods two 907 are fixedly mounted inside the cylinder 904. One moving block one 908 is slidably mounted on the outer sides of the two groups of limiting rods two 907. One inserting rod 909 is fixedly mounted on one side of each of the two groups of moving blocks one 908. One spring one 910 is sleeved on the outer sides of the two groups of limiting rods two 907. One inclined rod 902 is fixedly mounted on the top of each of the two groups of moving blocks one 908. The outer sides of the two groups of inclined rods 902 are slidably mounted inside the same cross plate 901. Two groups of limiting rods one 903 are fixedly mounted on the top of the cylinder 904. The two groups of limiting rods one 903 and the output shaft of the motor one 8 are slidably mounted inside the same cross plate 901. A screwdriver 906 is fixedly mounted on the bottom of the circular frame 905. Two groups of moving blocks two 16 are slidably mounted inside the sliding frame 10. One fixture 17 is fixedly mounted on one side of each of the two groups of moving blocks two 16.
[0022] In this embodiment, an electric push rod 4 is fixedly mounted on one side of the mounting plate 3. A fixed block 5 is fixedly mounted at the output end of the electric push rod 4. One connecting block one 6 is fixedly mounted at one end of the fixed block 5. One connecting block two 12 is fixedly mounted on one side of the sliding frame 10.

A damper 13 and a spring two 14 are fixedly mounted between the connecting block one 6 and the connecting block two 12. The spring two 14 is sleeved on the outer side of the damper 13. The settings of the spring two 14 and the damper 13 can effectively absorb and buffer these impact forces, reduce the damage to the clamping head structure, the screwdriver 906 and other components caused by the impact forces, and extend the service life of the equipment.
[0023] In this embodiment, two groups of chutes are opened inside the cylinder 904. The two ends of the two groups of limiting rods two 907 are fixedly mounted on the inner walls of the two sides of the corresponding chutes. The two groups of moving blocks one 908 are slidably mounted in the corresponding chutes. The two sides of the two groups of springs one 910 are respectively fixedly mounted on the moving block one 908 and the inner wall of one side of the chute. The chute provides an accurate movement track for the moving components of the clamping head, ensuring that the clamping head can move along a predetermined straight or curved track during the movement, thereby improving the position accuracy of clamping the screw.
[0024] In this embodiment, two groups of slots are opened inside both the cylinder 904 and the circular frame 905.

The support legs 2 provide stable support for the clamping head structure and can effectively bear various forces generated during the clamping screw process.
[0028] In the present embodiment, when in use, by toggling the horizontal plate 901 to move upward under the restriction of the limit rod 1 903, the two groups of inclined rods 902 and the moving block 1 908 are driven to approach each other, thereby driving the two groups of plug rods 909 to approach each other, and the spring 1 910 contracts to realize the cylinder 904 to unlock the circular frame 905, so that the screwdriver 906 of different models can be quickly replaced, and the two groups of moving blocks 1 908 can be driven to move away from each other under the action of the spring 1 910, thereby driving the plug rod 909 to move away from each other, and realizing the locking of the circular frame 905 and the cylinder 904, and the bidirectional screw rod 15 is driven to rotate by starting the motor 2 11, thereby driving the two groups of moving blocks 2 16 and the clamp 17 to move away from and approach each other, and starting The electric push rod 4 drives the fixed block 5 and the connecting block 6 to move downward. By setting the damper 13, the spring 14 and the connecting block 12, the electric push rod 4 can drive the sliding block 7 and the sliding frame 10 to move up and down at the same time. When the sliding frame 10 reaches the set position, the spring 14 and the damper 13 shrink, and the sliding frame 10 continues to move downward to screw the screw clamped by the clamp 17. In different production tasks, screwdrivers 906 of different specifications and types may need to be used to adapt to different screws. The quick disassembly and replacement function enables the automatic screw locking machine to flexibly select the appropriate screwdriver 906 according to the needs of the actual work scene to ensure the smooth progress of the work. The starting motor 8 drives the screwdriver 906 to rotate, thereby tightening the screw.
