TECHNICAL FIELD

[0001] The utility model belongs to the technical field of crimping machine, concretely relates to a wire harness and terminal crimping machine. BACKGROUND

[0002] The wire harness is a kind of assembly that multiple wires or cables are connected according to specific rules and order, mainly used for realizing the electrical signal transmission and control function between devices. When the wire harness is connected with the device, it needs to use the terminal, and if directly connected, it will cause the wire harness to be unstable, and the terminal is also called terminal, which is the connection hub between the wire cable and electrical equipment, electronic components.

[0003] In the actual application process of the wire harness and the terminal, the terminal needs to be fixed on both ends of the wire harness to facilitate the connection of the wire harness, and this operation needs to use the crimping machine. The crimping machine mainly relies on mechanical or hydraulic principle to generate strong pressure, and transmits the pressure to the wire and terminal to be connected through the crimping die. Under the action of pressure, the terminal deforms plastically, tightly wraps the wire, and forms a firm physical connection between the two, and also can damage the oxide layer on the surface of the wire and the terminal, to ensure good electrical conduction.

[0004] However, after the terminal deforms plastically, it will tightly fit the notch of the workbench. When the terminal is taken out, artificial can only take out the terminal by pulling the wire harness, but this way is easy to cause damage to the wire harness, and then affects the crimping quality.

Then, start hydraulic cylinder 3, its telescopic end starts to move downward and drive crimping block 4 to descend synchronously. With crimping block 4 gradually close and finally act on terminal body 6, under the strong pressure of continuous application, terminal body 6 occurs plastic deformation, tightly adheres to wire harness body 7, firmly combines, to complete this key crimping process.

[0027] Preferably: the surface of support plate 2 is provided with opening 16 for the movement of lifting plate 9, lifting plate 9 is connected with support plate 2 by electric cylinder 8, bidirectional threaded rod 12 is rotatably connected with rectangular block 10 by bearing, bidirectional threaded rod 12 is connected with the output shaft of servo motor 14, the size of threaded sleeve 13 and recess 11 is adapted, clamping block 15 is in the shape of "L".

[0028] In particular, when the terminal body 6 and the wire harness body 7 are connected, first, the power of the electric cylinder 8 is turned on, so that it is started and drives the lifting plate 9 to move downward. With the descent of the lifting plate 9, the rectangular block 10 connected thereto also descends synchronously until the clamping block 15 descends to a position below the recess of the machining table 5. Then, the servo motor 14 is started, and the motor output power drives the bidirectional threaded rod 12 to rotate smoothly inside the rectangular block 10 through the bearing. Since the threaded sleeve 13 is accurately matched in size with the groove 11, the threaded sleeve 13 does not rotate with the bidirectional threaded rod 12 during the rotation of the bidirectional threaded rod 12, but moves linearly along the threaded track on the surface of the bidirectional threaded rod 12. With the movement of the threaded sleeve 13, the clamping block 15 connected thereto also gradually approaches and tightly fits on both sides of the machining table 5. After the terminal body 6 and the wire harness body 7 are completed, the electric cylinder 8 and the lifting plate 9 work again to drive the rectangular block 10 to move upward. During the upward movement of the rectangular block 10, the clamping block 15 is synchronously driven to move upward, and then the clamping block 15 lifts the terminal body 6 that has been crimped out of the recess of the machining table 5. In this way, the traditional manual pulling of the wire harness body 7 to take out the terminal body 6 is effectively avoided, the possibility of damage to the wire harness body 7 due to external pulling is greatly reduced, the stability and reliability of the crimping quality are effectively guaranteed, and the overall production efficiency and product quality are improved.

[0030] In particular, when the terminal body 6 and the wire harness body 7 are connected, first, the power of the electric cylinder 8 is turned on, so that it is started and drives the lifting plate 9 to move downward. With the descent of the lifting plate 9, the rectangular block 10 connected thereto also descends synchronously until the clamping block 15 descends to a position below the recess of the machining table 5. Then, the servo motor 14 is started, and the motor output power drives the bidirectional threaded rod 12 to rotate smoothly inside the rectangular block 10 through the bearing. Since the threaded sleeve 13 is accurately matched in size with the groove 11, the threaded sleeve 13 does not rotate with the bidirectional threaded rod 12 during the rotation of the bidirectional threaded rod 12, but moves linearly along the threaded track on the surface of the bidirectional threaded rod 12. With the movement of the threaded sleeve 13, the clamping block 15 connected thereto also gradually approaches and tightly fits on both sides of the machining table 5. After the terminal body 6 and the wire harness body 7 are completed, the electric cylinder 8 and the lifting plate 9 work again to drive the rectangular block 10 to move upward. During the upward movement of the rectangular block 10, the clamping block 15 is synchronously driven to move upward, and then the clamping block 15 lifts the terminal body 6 that has been crimped out of the recess of the machining table 5. In this way, the traditional manual pulling of the wire harness body 7 to take out the terminal body 6 is effectively avoided, the possibility of damage to the wire harness body 7 due to external pulling is greatly reduced, the stability and reliability of the crimping quality are effectively guaranteed, and the overall production efficiency and product quality are improved.

Then start the servo motor 14, drive the bidirectional threaded rod 12 to rotate smoothly in the rectangular block 10. Because the threaded sleeve 13 is matched with the size of the groove 11, it moves linearly along the threaded track of the bidirectional threaded rod 12, and drives the clamping block 15 to gradually adhere to the two sides of the processing table 5. After the terminal body 6 and the wire harness body 7 are pressed and combined by the hydraulic cylinder 3 and the pressing block 4, the electric cylinder 8 and the lifting plate 9 cooperate again, drive the rectangular block 10 to rise, synchronously drive the clamping block 15 to lift, and smoothly take out the terminal body 6 that has been pressed from the recess of the processing table 5. This design replaces the traditional manual pulling operation of the wire harness body 7, greatly reduces the damage risk of the wire harness body 7, guarantees the stable and reliable pressing quality, improves the production efficiency and product quality.

[0032] After processing, connect the power supply of the electric lever 18, drive the concave block 19 to smoothly extend, and accurately move to the top of the recess of the processing table 5.
