Description

Technical Field

[0001] This utility model relates to a typing device, and more particularly to a quick conversion head for a typing device. Background Technology

[0002] In traditional typing devices, the engraving mold is fixed directly by the three-jaw chuck of a mechanical chuck. While this method achieves the purpose of normal processing, it requires frequent changes to the engraving mold each time. This necessitates frequent operation of the three-jaw chuck's jaws through the machine tool's operating holes to open and close them, making the operation cumbersome and reducing overall efficiency. Furthermore, directly clamping the engraving mold with the jaws can easily damage the mold or product, affecting its service life. Uneven clamping force due to mold damage can also lead to unstable clamping, thereby reducing processing accuracy and product qualification rate. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a quick conversion head for a typing device that can improve engraving efficiency and product qualification rate by providing fast clamping and stable rotation.

[0004] To solve the above-mentioned technical problems, the quick conversion head of the typing device of this utility model includes a main body with a positioning surface and a connecting part for fixing the claw at the rear end of the main body; the main body has a number of elastic pieces extending forward along the inner edge of the positioning surface, and each elastic piece surrounds to form a cylindrical structure for supporting the engraving mold. The engraving mold is fitted outside the cylindrical structure, and the elastic tension of each elastic piece is used to fix and lock the engraving mold.

[0005] Each elastic sheet gradually contracts inward from the root towards the head.

[0006] Each elastic sheet has at least one reinforcing block on its inner surface.

[0007] The main body is provided with a groove that matches the typing mold and is located between the elastic pieces.

[0008] Each elastic sheet has a boss located at its root on its outer surface.

[0009] The outer diameter of the connecting part is smaller than the outer diameter of the outer shell.

[0010] Advantages of this utility model:

[0011] The quick-change head, consisting of a main body with a positioning surface and a connecting part at the rear of the main body for locking with claws, allows for rapid replacement and securing of lettering dies clamped outside the elastic plates, significantly reducing clamping time. Simultaneously, after the elastic plate is inserted into the lettering die, the protrusion at the base of the elastic plate provides limiting, and the combined action of elastic tension and the outer surface protrusion achieves stable locking of the lettering die, avoiding the loosening and detachment phenomenon found in traditional devices, thus improving processing stability and reliability. Furthermore, each elastic plate gradually tapers inward from the base to the head, and the tilt of the elastic plate facilitates the fitting of the lettering die onto the outside. When changing lettering dies, automatic adaptation is achieved without manual adjustment of the elastic plate position, thereby improving assembly convenience. Attached Figure Description

[0015] The quick conversion head of the typing device of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] The quick-change head of this typing device includes a main body 1 with a positioning surface 3 and a connecting part 2 connected to the rear end of the main body 1 for chuck and jaw fixation. The outer diameter of the connecting part 2 is smaller than the outer diameter of the outer shell 3. The main body 1 has several elastic plates 4 extending forward along the inner edge of the positioning surface 3. Each elastic plate 4 forms a cylindrical structure for supporting the engraving mold. The engraving mold is fitted outside the cylindrical structure, and the elastic tension of each elastic plate 4 achieves fixation and locking of the engraving mold. The main body 1 has grooves that match the typing mold and are located between the elastic plates 4. The root of the outer surface of each elastic plate 4 has a boss 5 for limiting the engraving mold. Each elastic plate 4 gradually contracts inward from the root to the head for easy assembly. The quick fixation and stable locking of the engraving mold are achieved through the combined action of elastic tension and the outer surface protrusion 5. The inner surface of each elastic plate 4 has at least one reinforcing block 6 to improve the overall strength of the elastic plate and provide better guidance and support during clamping.

[0017] The following results were obtained after implementation and comparison with traditional typing devices:

[0018] (1) Clamping and engraving time: The original clamping and engraving time is 4 seconds / PCS, and the current clamping and engraving time is 1.5 seconds / PCS, saving 2.5 seconds / PCS of engraving time.

[0019] (2) The engraving processing fee for the original clamp is RMB 0.031 / PCS, while the engraving processing fee for the new clamp is RMB 0.012 / PCS, resulting in a saving of RMB 0.019 / PCS.

[0020] Comparison shows that the original clamping method involves slow mold replacement, easy disengagement during rotation after locking, and potential damage to products during locking, resulting in a lower pass rate. The current process allows for quick clamping and stable rotation, improving efficiency, increasing the pass rate, and bringing significant economic benefits.
