Description

Technical Field

[0001] This utility model relates to the field of cable processing technology, and in particular to a tube threading mechanism for wire gauge tubes. Background Technology

[0002] On the market, wire marking tubes are generally fitted onto cables, and most of them are flexible tubes that are processed into a flattened state.

[0003] Currently, the wire gauge tubes are often threaded manually, which involves manually inserting the cables into the tubes. This method is inefficient and time-consuming. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a cable insertion mechanism for cable marking tubes, which can replace manual labor in inserting cables into the marking tubes.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model provides a tube-threading mechanism for wire gauge tubes, including a turntable assembly and at least one tube-threading assembly disposed in the turntable assembly; the tube-threading assembly includes a guide sleeve and a movable rod movably disposed in the guide sleeve; the turntable assembly includes a turntable and an eccentric disk; the guide sleeve is fixedly connected to the turntable; the turntable rotates relative to the eccentric disk, and the eccentric disk drives the movable rod to extend or retract on the guide sleeve, thereby fitting the wire gauge tube onto the guide sleeve.

[0007] Furthermore, the tube-passing assembly also includes a rotating component and an elastic limiting unit connected to one end of the movable rod near the eccentric disk. The rotating component is rotatably mounted on the elastic limiting unit. The elastic limiting unit is used to restrict the rotating component so that the outer peripheral surface of the rotating component elastically slides against the outer peripheral surface of the eccentric disk.

[0008] Furthermore, the elastic limiting unit includes a support member and an elastic member. The support member has two support arms spaced apart. The rotating member is rotatably assembled between the two support arms via a pin. The outer peripheral wall of the eccentric disk is inserted between the two support arms with a clearance fit. The elastic member is disposed between the support member and the guide sleeve so that the outer peripheral surface of the rotating member can elastically slide against the outer peripheral surface of the eccentric disk.

[0009] Furthermore, the elastic element is a spring; and / or, the rotating element is a bearing.

[0010] Furthermore, multiple tube-passing assemblies are arranged in a ring around the turntable assembly at intervals, with each pair of tube-passing assemblies arranged opposite to each other.

[0011] Furthermore, the end of the movable rod away from the eccentric disc has a guide head, and when the guide head extends out of the guide sleeve, it is used to guide the wire tube to be sleeved on the guide sleeve.

[0012] Furthermore, the guide head is thicker at one end and thinner at the other end.

[0013] Furthermore, the guide head is tapered.

[0014] Furthermore, it also includes a lateral driver, which drives the turntable assembly to move synchronously with the tube-passing assembly.

[0015] Furthermore, the lateral actuator is a telescopic cylinder, and the telescopic end of the telescopic cylinder is connected to the turntable assembly.

[0016] The technical solution provided by this utility model has the following beneficial effects:

[0017] When one of the tube-threading components on the turntable assembly rotates to the infeed position, the eccentric disc drives the movable rod to extend out of the guide sleeve to fit the wire tube conveyed in the previous process onto the guide sleeve. Then, the tube-threading component with the wire tube fitted continues to rotate to the discharge position, and the eccentric disc drives the movable rod to retract on the guide sleeve to cooperate with the external clamping mechanism to fit the wire tube onto the cable. This can replace manual operation to thread the cable into the wire tube, saving time and effort, and significantly improving work efficiency. Attached Figure Description

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1 to 3 As shown, this embodiment provides a tube threading mechanism (hereinafter referred to as the threading mechanism) for wire number tubes, which serves as one of the mechanisms in the wire number tube threading device and enables the wire number tube with its opening already stretched to be threaded onto the cable.

[0024] like Figure 1 As shown, the tube-threading mechanism in this embodiment includes a turntable assembly 1 and six tube-threading assemblies 2 disposed on the turntable assembly 1. The six tube-threading assemblies 2 are arranged in a ring around the turntable assembly 1 at intervals. Of course, in other embodiments, the number of tube-threading assemblies 2 may be one, two, three, four, five, or more than seven.

[0025] Each tube assembly 2 includes a guide sleeve 21 and a movable rod 22 movably disposed within the guide sleeve 21.

[0026] Turntable assembly 1 includes, for example: Figure 1 The turntable 11 shown and as Figure 3 The eccentric disk 12 shown is equipped with a motor drive unit 13. The turntable 11 and the eccentric disk 12 are arranged in an upper and lower position. The turntable 11 is rotatable, and the eccentric disk 12 is fixed to the motor base of the motor drive unit 13.

[0027] like Figure 1 and Figure 2 As shown, the six guide sleeves 21 are fixed to the outer peripheral wall of the turntable 11 by the clamping connectors 5, and every two tube-passing assemblies 2 are arranged opposite each other to coordinate with the periodic rotation of the turntable 11. Therefore, the inlet position 14 and outlet position 15 of the tube-passing mechanism are located on the left and right opposite sides of the turntable 11, respectively.

[0028] The turntable 11 rotates relative to the eccentric disk 12, and the eccentric disk 12 drives the movable rod 22 to extend or retract on the guide sleeve 21, thereby fitting the wire tube onto the guide sleeve 21.

[0029] In this embodiment, as Figure 2 As shown, the tube assembly 2 also includes a rotating member 23 and an elastic limiting unit connected to one end of the movable rod 22 near the eccentric disk 12. The rotating member 23 is rotatably mounted on the elastic limiting unit, which is used to limit the rotating member 23 so that the outer peripheral surface of the rotating member 23 slides against the outer peripheral surface of the eccentric disk 12, thus forming an elastic connection.

[0030] More specifically, the elastic limiting unit includes an elastic element 25 and a U-shaped support element 24. In this case, the elastic element 25 is a spring 25', the rotating element 23 is a bearing 23', and the support element 24 has two support arms 241 spaced apart. Of course, in other embodiments, the elastic element 25 can also be an elastic element with a metal spring sheet structure.

[0031] The bearing 23' is rotatably mounted between the two support arms 241 via a pin 26. The outer peripheral wall of the eccentric disk 12 is inserted between the two support arms 241 with a clearance fit. The spring 25' is movably sleeved on the movable rod 22, and as... Figure 3 As shown, one end of the spring 25' is connected to the support member 24, and the other end of the spring 25' is connected to the guide sleeve 21.

[0032] like Figure 2 As shown, when the movable rod 22 retracts into the guide sleeve 21, the elastic element 25 applies a spring force in the direction of the eccentric disk 12 to ensure that the outer ring of the bearing 23' is elastically slidably in contact with the outer circumferential surface of the eccentric disk 12. At this time, the outer ring of the bearing 23' is the outer circumferential surface of the rotating element 23.

[0033] When one of the tube-threading components 2 on the turntable assembly 1 rotates to the infeed position 14 of the tube-threading mechanism, the eccentric disc 12 drives the movable rod 22 to extend on the guide sleeve 21 to fit the wire tube conveyed in the previous process onto the guide sleeve 21. Then, the tube-threading component 2 with the wire tube fitted on it is driven by the turntable 11 and continues to rotate to the discharge position 15 of the tube-threading mechanism. The eccentric disc 12 drives the movable rod 22 to retract on the guide sleeve 21 to cooperate with the external clamping mechanism to fit the wire tube onto the cable. This can replace the manual operation method to thread the cable into the wire tube, saving time and effort, and can also significantly improve the work efficiency.

[0034] In another preferred embodiment, such as Figure 1 and Figure 2 As shown, the end of the movable rod 22 away from the eccentric disk 12 has a guide head 221, which is specifically tapered. Of course, in other embodiments, the guide head 221 may also be pointed, trapezoidal, or other shapes that are thicker at one end and thinner at the other.

[0035] When the guide head 221 extends out of the guide sleeve 21, the wire tube used to guide the previous process is sleeved on the guide sleeve 21 along the guide head 221.

[0036] In another preferred embodiment, such as Figure 1 As shown, the tube-threading mechanism in this embodiment also includes a lateral driver 3, specifically a telescopic cylinder. The telescopic end of the telescopic cylinder is connected to the drive motor unit of the turntable assembly 1 to ensure that the turntable assembly 1 and the tube-threading assembly 2 move synchronously to the left and right.

[0037] In this specific embodiment, the horizontal driver 3 is mounted on the frame, and the motor mount of the motor drive unit 13 is also mounted on the frame through the horizontal guide rail structure to ensure that the turntable assembly 1 and the tube insertion assembly 2 can move horizontally left and right as a whole to complete the tube insertion operation.

[0038] like Figure 1 As shown, the frame is also equipped with a travel limiter 4 for limiting the movement of the tube-through assembly 2 toward the discharge port 15.

[0039] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
