Description

Technical Field

[0001] This utility model relates to the field of terminal breakers, and more specifically, to a multi-core wire terminal breaker with a positioning structure. Background Technology

[0002] With the continuous improvement of industrial automation, multi-core cables, as the core carrier of power transmission and signal control, are widely used in new energy vehicles, intelligent equipment, communication equipment and other fields. The processing quality of multi-core cables directly affects the reliability of equipment operation. As a key piece of equipment for stripping and crimping wire ends, the performance of the terminal crimping machine has a significant impact on the wire processing efficiency and yield. Traditional terminal crimping machines mostly rely on mechanical clamping in one direction or simple grooves to limit the wire. This design is difficult to achieve a stable and reliable fixing effect when dealing with multi-core cables of different specifications, and conventional cutting tools are difficult to adapt to the processing of wires of different sizes.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. Figure 1 This is a schematic diagram of a multi-core wire termination machine with a positioning structure provided in an embodiment of this utility model. Figure 2 This is an exploded view of a multi-core wire termination machine with a positioning structure provided in an embodiment of this utility model. Figure 3 This is a schematic diagram of the structure of the first blade holder in a positioning structure provided by an embodiment of the present invention. Figure 4 This is a schematic diagram of a mounting frame with a positioning structure provided in an embodiment of the present utility model. The following is a detailed description of a multi-core wire termination machine with a positioning structure.

[0023] A multi-core wire termination machine with a positioning structure includes an operating table 100 and a fixed frame 101. The fixed frame 101 is provided on the top of the operating table 100. A wire 102 is provided at one end of the fixed frame 101. Two sets of positioning wheels 103 are provided in the middle of the fixed frame 101. A hand crank 104 is provided on one side of the fixed frame 101. By rotating the hand crank 104, one set of positioning wheels 103 can be rotated. After the wire 102 is inserted into the groove between the two sets of positioning wheels 103, the wire 102 can be pushed forward into the stripping area. The positioning wheels 103 can be pushed forward into the stripping area. The top of the operating table 100 is provided with a first blade holder 105 and a mounting frame 106. The top of the first blade holder 105 is provided with a first blade 107. The top of the first blade 107 is provided with a second blade 108 and a second blade holder 109. The top of the mounting frame 106 is provided with a first hydraulic cylinder 110.

[0024] The mounting bracket 106 is provided with a guide rail 111, a first sliding table 112 and a second sliding table 113 at one end. The top of the first sliding table 112 is provided with a pneumatic gripper 122 and an electric telescopic rod 121, and the top of the second sliding table 113 is provided with a second hydraulic cylinder 114.

[0025] The fixed frame 101 has connection holes on both sides, and two sets of rotating shafts are inserted through the multiple sets of connection holes. One set of rotating shafts has a protrusion integrally formed on it. A hand crank 104 is detachably connected to one side of one set of rotating shafts. When the hand crank 104 is rotated, the corresponding positioning wheel 103 can be rotated due to the protrusion. A sleeve is fitted on the hand crank 104 to reduce friction when rotating the hand crank 104, making the rotation of the hand crank 104 smooth and improving the practicality of the end-cutting machine. Positioning wheels 103 are fitted on both sets of rotating shafts.

[0026] The top of the operating table 100 is detachably connected to a mounting bracket 106 and a first blade holder 105. A first blade 107 is bolted to the top of the first blade holder 105, and a second blade 108 is bolted to the bottom of the second blade holder 109. Bolting the first blade 107 and the second blade 108 improves the fixation of the blades, preventing them from shaking during peeling and cutting, thus affecting the peeling effect. One side of the first blade 107 contacts the second blade 108, and the cutting edges of the first blade 107 and the second blade 108 are in close contact to ensure a good peeling effect. Positioning frames 116 are fixedly connected to both sides of the frame 106. The positioning frames 116 can limit the direction in which the wire 102 is pushed by the positioning wheel 103, so as to prevent the wire 102 from deviating and being damaged, thus improving the reliability of the end-cutting machine. The wire 102 passes through the two sets of positioning frames 116. The wire 102 is held between the first blade 107 and the second blade 108. Both the first blade 107 and the second blade 108 are "V" shaped. The "V" shaped blade can meet the stripping processing of more specifications of wire 102, thus improving the applicability of the end-cutting machine.

[0027] Both sides of the inner wall of the mounting bracket 106 are fixedly connected to the first protrusion 117, and both sides of the second blade holder 109 are integrally formed with the second protrusion 118. Two sets of springs 119 are respectively connected between the two sets of first protrusions 117 and the two sets of second protrusions 118. When the first hydraulic cylinder 110 pushes the second blade holder 109 to complete one peeling cut, the main shaft of the first hydraulic cylinder 110 retracts. At this time, the springs 119 assist the second blade holder 109 to reset so as to ensure that the second blade holder 109 is in close contact with the main shaft of the first hydraulic cylinder 110 when the first hydraulic cylinder 110 pushes forward next time, thereby improving the automation level of the end-cutting machine.

[0028] The top of the control panel 100 is fixedly connected to the mounting platform 120, and the top of the mounting platform 120 is detachably connected to the guide rail 111. The top of the guide rail 111 is fitted with a first sliding table 112 and a second sliding table 113. The first sliding table 112 and the second sliding table 113 can be electric sliding tables.

[0029] The top of the first sliding table 112 is integrally formed with a mounting base, and an electric telescopic rod 121 is detachably connected inside the mounting base. One end of the electric telescopic rod 121 is connected to a pneumatic gripper 122. The top of the second sliding table 113 is detachably connected to a connecting frame 115, and the bottom of the connecting frame 115 is connected to a second hydraulic cylinder 114. After the wire 102 has been stripped, the pneumatic gripper 122 clamps the cut-off rubber, the main shaft of the electric telescopic rod 121 retracts, and drives the pneumatic gripper 122 to pull out the cut-off rubber. At this time, the first sliding table 112 and the second sliding table 113 slide along the guide rail 111 until the second hydraulic cylinder 114 is aligned with the wire 102. At this time, the second hydraulic cylinder 114 knocks the terminal to the end of the wire 102, completing the terminal knocking operation.

[0030] Both sets of positioning wheels 103 have grooves on their sides, and wires 102 are secured between the two sets of grooves.

[0031] The top of the mounting bracket 106 is detachably connected to a first hydraulic cylinder 110, and the bottom of the first hydraulic cylinder 110 contacts the second blade holder 109.
