Description

Technical Field

[0001] The invention relates to the field of signal wiring, in particular to an automatic wire end termination machine for an O-type connecting piece and the connecting piece. Background Art

[0002] Railway signal and industrial control signal wiring operations involve many cables and complex joints. Currently, cold terminals are mostly used for construction. There are many types of cold terminals, and each terminal has different usage scenarios and construction processes. Among them, O-type connector crimping technology is often used in places with more vibrations. The O-type connector crimping construction can be roughly divided into four steps: wire stripping, loop folding, length adjustment and crimping, which is very cumbersome. Even skilled workers can only complete the production of seventy or eighty wire ends a day, which has become one of the important reasons restricting the speed of on-site construction; at the same time, the signal line connection plates along the railway are basically outdoors, which are easily affected by the scorching sun and high temperature during construction. Speeding up the production of wire ends can also protect the health of workers to the greatest extent.

[0003] Therefore, it is imperative to develop a set of equipment that can be used in the line terminal board and can realize automatic termination of O-type crimping. If automatic termination is to be achieved, the continuous supply of connecting pieces must be guaranteed, because the wire cup of the traditional connecting piece bulges upward when it is not in use, such as Fig. 9 As shown, it is not convenient for continuous supply, so in order to cooperate with the design of automatic terminal equipment, a new type of connecting piece is developed.

The automatic termination of the wire ends of the O-type connecting piece is realized, which improves efficiency, reduces labor intensity, and can also protect the health of workers to the greatest extent.

[0035] In the figure, the ring cutting mechanism and the transfer mechanism are located at both ends of the mounting plate 1. This is to clearly show the specific structure. However, in actual application, when the ring cutting mechanism is located in the middle position, the transfer mechanism is located at the rightmost end, and when the ring cutting mechanism is located at the leftmost end, the transfer mechanism is located in the middle position.

[0036] like Figure 1 , Figure 4 and Figure 5As shown, the ring cutting mechanism includes a first mobile frame 2 arranged at the front end of the mounting plate 1 and moving at the front end of the mounting plate, a cutting knife 3 symmetrically arranged in the first mobile frame 2, and a cutting knife 4 symmetrically arranged in the first mobile frame 2 and lifted and lowered in the first mobile frame 2, the lower end of the cutting knife 4 is an arc groove, and the upper and lower ends of the first mobile frame 2 are provided with a slider moving in the first mobile frame 2, and a compression spring driving the slider to move upward is provided in the first mobile frame 2. The compression spring pushes the slider upward to ensure that the cutting knife 4 will not block the cable from moving forward when the cable is conveyed. This is not shown in the figure. This is the prior art and will not be described in detail here. When the first mobile frame 2 moves to the middle position, the conveying mechanism conveys the cable backward, and the cutting knife 3 cuts the rubber layer of the cable longitudinally. After reaching the required length, the cutting knife 4 moves inward in the same direction to cut the cut rubber layer, thereby obtaining a copper core of the required length.

[0038] like Figure 2 , Figure 6 and Figure 7 As shown, the transfer mechanism includes a second mobile frame 14 that is arranged at the front end of the mounting plate 1 and moves at the front end of the mounting plate, a support seat 15 that is arranged in the second mobile frame 14 and is used to support the O-type connecting piece, and a first pressure head 16 that is arranged at the upper end of the second mobile frame 14 and is raised and lowered at the upper end of the second mobile frame 14; the O-type connecting piece in the storage mechanism moves forward to the support seat 15, and then the second mobile frame 14 moves to the middle position of the mounting plate 1, the copper core enters the wire cup of the O-type connecting piece, and the first pressure head 16 descends to extrude the wire cup into shape and wrap the copper core, thereby realizing automatic termination of the wire end.

[0039] like Figure 1 and Figure 3As shown, the storage mechanism includes a storage slot 19 provided on the upper mounting plate 1 and a push plate 20 provided on the upper mounting plate 1 and moving on the upper mounting plate 1. The upper mounting plate 1 is provided with an electric cylinder for driving the push plate 20 to move, which is not shown in the figure. This is a prior art and will not be described in detail here. The bottom of the storage slot 19 is provided with openings at both ends. When the push plate 20 moves forward, the O-type connecting piece is output from the storage slot 19 through the opening position. When the second moving frame 14 moves to the rightmost end, the push plate 20 moves forward, pushes the O-type connecting piece at the bottom of the storage slot 19 forward, and pushes it onto the support seat 15, realizing the automatic loading of the O-type connecting piece.

[0041] like Figure 3 As shown, a limit head 13 for limiting the end of the copper core is provided on the mounting plate 1 at the lower end.

[0042] like Figure 7 As shown, a baffle 17 is provided at the right end of the support seat 15, and the position of the O-shaped connecting piece is positioned by the baffle 17. A pressing plate 18 is provided at the left end of the first pressing head 16. When the first pressing head 16 descends, the wire cup is formed.

[0043] like Figure 1 As shown, a fixing frame 21 is provided at the front end of the mounting plate 1 .

[0044] like Figure 1 As shown, brackets 22 are provided at both upper and lower ends of the fixed frame 21, and a second pressing head 23 is provided on the bracket 21, which is raised and lowered on the bracket 21.

When the first movable frame 2 moves to the bracket position, the two second pressing heads 23 move inward synchronously, and the extrusion and cutting knife 4 moves inward to cut the rubber layer. When the second movable frame 14 moves to the bracket position, the two second pressing heads 23 move inward synchronously, press the second pressing heads downward, and extrude the wire cup into shape.

[0045] like Figure 2As shown, the fixing frame 21 at the lower end is provided with a fixing plate 24 and a rotating plate 25 rotatably connected between the front end and the lower fixing frame 21, and the lower fixing frame 21 is provided with a motor for driving the rotating plate 25 to rotate. After the copper core is bent, the rotating plate 25 rotates backward to cooperate with the fixing plate 24 to preliminarily fix the copper core. After the second moving frame moves to the middle position, the copper core can completely enter the wire cup, and the reliability is good.

[0046] like Figure 1 As shown, the conveying mechanism includes conveying wheels 26 respectively arranged at the front end of the fixed frame 21, and a bracket for supporting the conveying wheel 26 is provided at the front end of the fixed frame 21. The conveying wheel 26 rotates in the bracket. Two conveying wheels 26 are provided in each bracket.

The bracket is provided with a motor for driving the conveying wheel 26 to rotate, which is not shown in the figure. The motor drives the conveying wheel 26 to rotate, thereby conveying the cable backward.

[0047] like Figure 1 As shown, the front end of the mounting plate 1 is provided with a slide groove, the rear ends of the first mobile frame 2 and the second mobile frame 14 are provided with sliders that cooperate with the slide groove, and the two fixed frames 21 are provided with screws that cooperate with the mobile frames of the circular cutting mechanism and the transfer mechanism. The mobile frame is driven to move by the screw, and a motor for driving the screw to rotate is provided on the side of the fixed frame, which is not shown in the figure. This is a prior art and will not be described in detail here.

[0048] like Figure 8 As shown, an O-type connecting piece, applied to the terminal, comprises a connecting piece 27, a wire cup 28 and an insulating buckle 29 arranged on the connecting piece 27, wherein the opening of the wire cup 28 faces left. Fig. 9 As mentioned above, in the prior art, the openings of the wire cup 28 and the insulating buckle 29 face upward, which is not convenient for continuous supply. The wire cup and insulating buckle of the traditional crimping piece are changed to a single-sided connection and horizontal arrangement. The horizontal arrangement allows the crimping pieces to be stacked in order without affecting the crimping pieces above, and is less likely to cause errors; the single-sided connection allows the crimping piece to enter the working position from the side, which is convenient for the movement of the automatic crimping equipment and ensures the continuous supply of the connecting piece.
