Description

Technical Field

[0001] The present invention relates to a floating pusher and a crimping device including the floating pusher. Background Technology

[0002] In existing technology, crimping equipment is typically used to crimp terminals onto the ends of wires. This crimping equipment usually includes a wire clamp, a positioning base, a crimping tool, and a crimping machine. The wire is clamped and secured to the wire clamp, and the terminal is positioned on the positioning base. The crimping tool is located above the positioning base and connected to the crimping machine. The crimping machine drives the crimping tool to move vertically. Driven by the crimping machine, the crimping tool pushes the crimping portion of the terminal to crimp the end of the wire. In existing technology, the wire clamp remains stationary during crimping and does not move synchronously with the crimping tool, which can cause the wire to bend or deform during the crimping process. If the wire is a flexible wire, some bending and deformation is not a problem. However, if the wire is a hard and brittle material, it can cause irreversible plastic deformation or breakage. Therefore, existing crimping equipment is not suitable for crimping terminals onto rigid wires. Summary of the Invention

[0003] The purpose of this invention is to solve at least one aspect of the aforementioned problems and defects existing in the prior art.

[0004] According to one aspect of the present invention, a floating pusher is provided.

The spring constant of the lower spring is less than that of the upper spring. The connecting assembly is used to connect to a crimping machine of a crimping apparatus to move synchronously with the crimping tool of the crimping apparatus. The lower flange is used to push against a floating retainer of the crimping apparatus for holding a rigid wire to push the floating retainer to a predetermined position and hold it therein.

[0011] According to another exemplary embodiment of the present invention, the upper end of the vertical rod is threaded or welded to the positioning part of the connecting column.

[0012] According to another exemplary embodiment of the present invention, the vertical rod and the connecting column are integral parts.

[0013] According to another exemplary embodiment of the present invention, a horizontal connecting hole is formed on the connecting block to allow a connecting bolt to pass through, such that the connecting block can be fastened to the crimping machine of the crimping device by a connecting bolt passing through the horizontal connecting hole.

[0014] According to another aspect of the present invention, a crimping apparatus is provided.

[0015] According to an exemplary embodiment of the present invention, the crimping tool is adapted, driven by the crimping machine, to move downward from an initial position not in contact with the terminal to an initial crimping position in contact with the terminal and from the initial crimping position to a final crimping position for crimping the terminal onto the rigid wire.

[0016] According to another exemplary embodiment of the present invention, when the crimping tool is moved from the initial position to the initial crimping position, the floating retainer moves downward from the starting position to a predetermined position under the pressure of the floating pusher; when the floating retainer is moved from the starting position to the predetermined position, the rigid wire is moved from a position not in contact with the floating retainer to a position in contact with the elastic support, such that the end of the rigid wire is supported on the elastic support.

[0017] According to another exemplary embodiment of the present invention, when the crimping tool is in the initial position, the lower flange of the floating pusher is not in contact with the floating retainer and the upper and lower springs of the floating pusher are in an initial state without external compression; when the crimping tool is in the initial crimping position, the lower flange of the floating pusher presses against the floating retainer and the upper and lower springs of the floating pusher are in an initial compressed state to apply a first pressing force to the floating retainer; when the crimping tool is in the final crimping position, the lower flange of the floating pusher presses against the floating retainer and the upper and lower springs of the floating pusher are in a final compressed state to apply a second pressing force greater than the first pressing force to the floating retainer.

During the movement of the connecting assembly 2 of the crimping tool 300 and the floating pusher 100 from the final crimping position to the initial position, the upper spring 51 and lower spring 52 of the floating pusher 100 gradually return from the final compressed state to the initial state where they are not compressed by external force.

The crimping device according to claim 11, characterized in that: The crimping tool (300) is adapted to move downward from an initial position not in contact with the terminal (8) to an initial crimping position in contact with the terminal (8) and from the initial crimping position to a final crimping position where the terminal (8) is crimped onto the rigid wire (7) under the drive of the crimping machine (200).

13. The crimping device according to claim 12, characterized in that: When the crimping tool (300) is moved from the initial position to the initial crimping position, the floating retainer (400) moves downward from the starting position to the predetermined position under the pressure of the floating pusher (100); When the floating retainer (400) is moved from the starting position to the predetermined position, the rigid wire (7) is moved from a position not in contact with the floating retainer (400) to a position in contact with the elastic support (500), such that the end of the rigid wire (7) is supported on the elastic support (500).

14. The crimping device according to claim 13, characterized in that: When the crimping tool (300) is in the initial position, the lower flange (4) of the floating pusher (100) is not in contact with the floating retainer (400) and the upper spring (51) and lower spring (52) of the floating pusher (100) are in an initial state without external compression. When the crimping tool (300) is in the initial crimping position, the lower flange (4) of the floating pusher (100) presses against the floating retainer (400) and the upper spring (51) and lower spring (52) of the floating pusher (100) are in the initial compression state to apply a first pressing force to the floating retainer (400); When the crimping tool (300) is in the final crimping position, the lower flange (4) of the floating pusher (100) presses against the floating retainer (400) and the upper spring (51) and lower spring (52) of the floating pusher (100) are in the final compressed state to apply a second pressing force greater than the first pressing force to the floating retainer (400).

15. The crimping device according to claim 14, characterized in that: After the terminal (8) is crimped onto the rigid wire (7), the crimping machine (200) drives the connection assembly (2) of the crimping tool (300) and the floating pusher (100) to move upward from the final crimping position to the initial position; During the process of the connection assembly (2) of the crimping tool (300) and the floating pusher (100) moving from the final crimping position to the initial position, the upper spring (51) and lower spring (52) of the floating pusher (100) gradually return from the final compressed state to the initial state where they are not compressed by external force.

16. The crimping device according to claim 15, characterized in that: The floating retainer (400) includes: Fixture (401); Floating frame (402); and The first spring (403) is compressed between the floating frame (402) and the fixed frame (401). The rigid wire (7) is held to the floating frame (402) so that it can float with the floating frame (402) relative to the fixed frame (401) between the starting position and the predetermined position.

17. The crimping device according to claim 16, characterized in that: A limiting part (404) is formed on the fixed frame (401). When the floating frame (402) is moved to the predetermined position, the limiting part (404) abuts against the floating frame (402) to restrict the floating frame (402) to the predetermined position.

18. The crimping device according to claim 15, characterized in that: The elastic support base (500) includes: Fixture (501); Floating seat (502); and The second spring (503) is compressed between the fixed seat (501) and the floating seat (502). The end of the rigid wire (7) is supported on the top of the floating seat (502).
