[0030] Example:

[0031] like Figure 1-5 As shown, this utility model discloses an adjustable output force spring compression and release electric reciprocating device, comprising a device body, characterized in that:

[0032] It includes a launch trigger gear 1 connected to the output shaft of the geared motor 100, a limit slider trigger dial 2 mounted on the launch trigger gear 1, a connecting module 3, a limit slider 4, and a pull rod 5.

[0033] The connecting module 3 connects the geared motor 100 and the pull rod 5 to form an integral structure. The bottom of the connecting module 3 is provided with a hollow adjusting bolt 6. The pull rod 5 is fitted inside the connecting module 3 and the hollow adjusting bolt 6. The top of the connecting module 3 abuts against the limit ring 9 to ensure stable connection and coordinated operation between the components.

[0034] The pull rod 5 is provided with a lifting tooth 7, a limiting groove 8 and a limiting retaining ring 9. The lifting tooth 7 meshes with the ejection trigger gear 1 to realize the lifting of the pull rod 5 and the compression of the large spring 12. The limiting retaining ring 9 is located near the upper end of the pull rod 5 and is used to limit the stroke of the pull rod 5.

[0035] The outer periphery of the connecting module 3 is provided with a receiving groove 10 for placing the limiting slider 4. The limiting slider 4 is connected to a small spring 41. Under the action of the small spring 41, it slides into the limiting groove 8 on the pull rod 5 and cooperates with the limiting groove 8 to lock the pull rod 5. When the limiting slider triggers the dial 2 to rotate, it can move the limiting slider 4 to release the pull rod 5.

[0036] A precision locking nut 11 is fitted on the outer wall of the hollow adjusting bolt 6. A large spring 12 is fitted on the outside of the combination of the pull rod 5 and the hollow adjusting bolt 6. The upper end of the large spring 12 contacts the precision locking nut 11, and the lower end is provided with a fixed base 13 fitted on the pull rod 5 to limit the compression stroke and position of the large spring 12.

[0037] The bottom end of the pull rod 5, located at the center of the fixed base 13, is threaded with a spring head 14, which is used to provide impact kinetic energy when the large spring 12 is released.

[0038] The precision locking nut 11 has a fixing hole 15 at each diagonal point for locking the nut, which facilitates position locking and ensures stable position after adjustment.

[0039] Working principle

[0040] Start the reduction motor, and the ejector trigger gear meshes with the lifting gear on the lever to lift the lever and compress the large spring;

[0041] When the large spring is compressed to the set position, the limit slider slides into the limit groove on the pull rod under the action of the small spring, locking the pull rod and keeping the large spring in a compressed state.

[0042] When the large spring needs to be released, the geared motor will activate again, driving the limit slider to trigger the dial to rotate. The dial will move the limit slider to overcome the friction between the pull rod limit groove and the limit slider after the large spring is compressed, and slide it out of the limit groove to release the pull rod.

[0043] At the moment of release, the large spring converts its stored energy into kinetic energy, which is then used to provide impact through the striking head, thus realizing the reciprocating motion of the large spring compression, locking, and striking.

[0044] Adjust the output force value

[0045] By adjusting the position of the precision locking nut on the outer wall of the hollow adjusting bolt, the preload of the large spring can be changed, thereby adjusting the output force of the device. After adjustment, the nut is locked through the fixing hole to ensure stable position and guarantee the accuracy and consistency of the output force.

[0046] Application Scope

[0047] This utility model's adjustable output force spring compression and release electric reciprocating device can be widely used in various scenarios such as spring impactors, mortar penetration instruments, orthopedic nail removal, and automotive sheet metal work, providing an efficient and convenient solution for industrial production and medical practice.

[0048] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
