[0002] A wire harness is a composition composed of multiple wires or cables; it is used to transmit power, signals or data between electronic devices and electrical appliances; it enables the flow of current by establishing connections between two or more isolated electronic circuits, supporting the functions of various electronic components; as a kind of production tool for automotive wire harnesses, the tooling plate plays a crucial role; the tooling plate positions, clamps and tests the wire harness through a wire harness binding glue tooling fixture; thereby preventing them from moving or deforming during the production process, making the production process more precise.

[0003] However, in the assembly process of existing new energy vehicle wire harnesses, different types of wire harnesses and connectors need to adopt different fixing methods to ensure the assembly quality and efficiency. The types of wire harnesses are mainly divided into wire harnesses with or without connectors; for wire harnesses that require the use of connectors, the connectors usually need to be fixed into the plastic housing before assembly; that is, the connector is placed into the plastic housing and fixed in the plastic housing through mechanisms such as buckles and latches; while for wire harnesses without connectors, they need to be directly inserted onto the corresponding fixing forks during assembly; this results in frequent replacement of the fixing forks and plastic housings on the station plate when assembling different wire harnesses, which will consume additional time, cause the production line to stop, and affect the overall production efficiency.

[0004] In view of this, in order to overcome the above technical problems, the utility model proposes a wire harness general assembly tooling fixture, which solves the above technical problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, the utility model proposes a wire harness general assembly tooling fixture. By setting a U-shaped frame, the plastic housing is rotatably connected to the frame body through the U-shaped frame, so that the user can rotate the U-shaped frame to switch the use of the fixing fork and the plastic housing, thus eliminating the need for the user to repeatedly disassemble and replace the plastic housing and the fixing fork to fix the wire harnesses with or without connectors. Furthermore, when assembling different wire harnesses, the user only needs to rotate the U-shaped frame to replace the fixing fork and the plastic housing on the station plate, which will reduce the consumption of additional time, shorten the downtime of the production line, and thus improve the overall production efficiency; making the practical application effect of the utility model further improved.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A wire harness assembly tool of the utility model includes a frame body and a working station plate; a connecting frame is rotatably connected to the upper end of the frame body; an electric roller is rotatably installed at the upper end of the connecting frame; sliding grooves are opened on both sides of the frame body; a bracket is slidably connected in the sliding grooves; a groove is opened on the side wall of the working station plate; a plug rod is slidably and hermetically connected in the groove; a connecting spring is arranged between the plug rod and the bottom of the groove; one end of the connecting spring is fixedly connected to the bottom of the groove, and the other end is fixedly connected to the plug rod; clamping grooves matched with the plug rod are opened on the surfaces of the two brackets close to each other; an electromagnetic sheet is embedded at the bottom of the groove.

[0007] Preferably, a threaded groove communicated with the sliding groove is opened on the side wall of the frame body; a screw rod is threadedly connected in the threaded groove.

[0008] Preferably, a handle is fixedly connected to the end of the screw rod away from the threaded groove; an elastic block is rotatably connected to the end of the screw rod away from the handle; the elastic block is made of fluororubber material.

[0009] Preferably, a V-shaped groove is opened at the end of the elastic block away from the screw rod.

[0010] Preferably, a strip-shaped groove is opened on the side wall of the bracket; a slider is slidably connected in the strip-shaped groove; the clamping groove is opened on the surface of the slider close to the working station plate; a lead screw is rotatably connected in the strip-shaped groove; the slider is in screw transmission connection with the lead screw.

[0011] The beneficial effects of the utility model are as follows:

[0012] By setting a U-shaped frame, the utility model enables the rubber shell to be rotatably connected to the frame body through the U-shaped frame, so that the user can rotate the U-shaped frame to switch the use of the fixing fork and the rubber shell, thus eliminating the need for the user to repeatedly disassemble and replace the rubber shell and the fixing fork to fix the wire harness with or without plug-in components. Furthermore, when assembling different wire harnesses, the user only needs to rotate the U-shaped frame to replace the fixing fork and the rubber shell on the working station plate, which can reduce the consumption of extra time, shorten the downtime of the production line, and improve the overall production efficiency; the practical application effect of the utility model is further improved.

[0013] By setting a rotating ring, the utility model facilitates the user to rotate the rotating ring, enabling the rotating ring to drive the fork body in screw transmission connection with it to rotate relative to the rotating ring. Since the fork body is slidably connected to the installation groove through a slider, rotating the rotating ring can make the rotating ring drive the fork body to vertically extend out of the installation groove, changing the length of the fork body to meet the user's needs, helping to fix heavy or complex wire harnesses or improving the flexibility of assembly, and being applicable to lightweight components; the practical application effect of the utility model is further improved.

[0023] As an implementation manner of the present utility model, the fixing fork 2 includes a fork body 22 and an inserting rod 23; circular grooves 24 are formed at both ends of the fork body 22; the inserting rod 23 is slidably connected in the circular groove 24; a magnet 25 is embedded at one end of the inserting rod 23 close to the bottom of the circular groove 24; an electromagnetic sheet 26 is embedded at the bottom of the circular groove 24.

[0024] As an implementation manner of the present utility model, a connecting groove 111 is formed at the lower end of the plastic shell 11; the connecting groove 111 is arranged in a T shape; a connecting rod 121 is fixedly connected to the upper end of the U-shaped frame 12; the connecting rod 121 is slidably connected in the connecting groove 111.

[0025] As an implementation manner of the present utility model, an airbag 15 is arranged in the connecting groove 111; one end of the airbag 15 is fixedly connected to the side wall of the connecting groove 111; a return spring 151 is arranged inside the airbag 15.

[0026] As an implementation manner of the present utility model, a pushing piece 152 is fixedly connected to one end of the airbag 15 away from the side wall of the connecting groove 111; the pushing piece 152 is in sliding and sealing contact with the groove wall of the connecting groove 111; the pushing piece 152 is made of PTFE material.

[0027] As an implementation manner of the present utility model, a strip-shaped groove 16 communicating with the connecting groove 111 is formed in the side wall of the plastic shell 11; a blocking rod 161 is slidably and sealingly connected in the strip-shaped groove 16; magnetic blocks 17 are fixedly connected to both sides of the frame body 1.

[0028] During operation, in the assembly process of existing new energy vehicle wiring harnesses, different types of wiring harnesses and connectors need to adopt different fixing methods to ensure the assembly quality and efficiency. The types of wiring harnesses are mainly divided into wiring harnesses with and without connectors; for wiring harnesses that require the use of connectors, the connectors usually need to be fixed in the plastic shell 11 before assembly; that is, the connectors are placed into the plastic shell 11 and fixed in the plastic shell 11 through mechanisms such as buckles and latches; for wiring harnesses without connectors, they need to be directly inserted onto the corresponding fixing fork 2 during assembly; this results in frequent replacement of the fixing fork 2 and the plastic shell 11 on the workbench when assembling different wiring harnesses, which will consume additional time, cause the production line to stop, and affect the overall production efficiency.

[0029] In this regard, the utility model is provided with a U-shaped frame 12, so that the rubber shell 11 is rotatably connected to the frame body 1 through the U-shaped frame 12. Thus, the user can rotate the U-shaped frame 12 to switch the use of the fixing fork 2 and the rubber shell 11, without the need for the user to repeatedly disassemble and replace the rubber shell 11 and the fixing fork 2 to fix the wire harness with or without plug-in components. Furthermore, when assembling different wire harnesses, the user only needs to rotate the U-shaped frame 12 to replace the fixing fork 2 and the rubber shell 11 on the workbench, which can reduce the consumption of extra time, shorten the downtime of the production line, and thus improve the overall production efficiency, further enhancing the practical application effect of the utility model.

[0030] In the initial state, the stop lever 161 is located in the strip-shaped groove 16 on the side wall of the rubber shell 11. The airbag 15 in the connecting groove 111 is in a slightly compressed state under the block of the stop lever 161, and the return spring 151 in the airbag 15 is in a compressed state. Before installing the rubber shell 11 on the U-shaped frame 12, the user needs to pull out the stop lever 161 in the strip-shaped groove 16. At this time, the stop lever 161 no longer blocks the airbag 15 in the connecting groove 111, enabling the return spring 151 inside the airbag 15 to stretch under the action of the elastic restoring force. The stretched return spring 151 can push the airbag 15 to stretch, causing the airbag 15 to push the push piece 152 to extend towards the notch of the connecting groove 111, and the push piece 152 can push the dust in the connecting groove 111 out of the notch of the connecting groove 111, thus ensuring the cleanliness of the connecting groove 111. Moreover, the push piece 152 is made of PTFE material, making the surface of the push piece 152 smooth and preventing dust from adhering to the surface of the push piece 152. Subsequently, the notch of the connecting groove 111 is aligned with the connecting rod 121 of the U-shaped frame 12, enabling the connecting rod 121 to be inserted into the connecting groove 111. The connecting rod 121 can push the airbag 15 to contract through the push piece 152, causing the airbag 15 to squeeze the internal return spring 151 to contract. Since the airbag 15 is provided with air holes communicating with the outside, the gas in the compressed airbag 15 can be discharged through the air holes to ensure that the airbag 15 is compressed. When the connecting rod 121 passes over the connecting groove 111, the airbag 15 is in a fully compressed state. At this time, the user inserts the stop lever 161 into the strip-shaped groove 16, enabling the stop lever 161 to block the connecting rod 121 inserted into the connecting groove 111, fixing the connecting rod 121 in the connecting groove 111, and thus enabling the U-shaped frame 12 to be fixedly connected to the rubber shell 11 through the connecting rod 121.

[0031] After the plastic shell 11 is installed, the frame 1 with the plastic shell 11 is fixed at the defined position on the workbench. Since the U-shaped frame 12 is rotatably connected to the frame 1 and the U-shaped frame 12 is made of iron material, when the U-shaped frame 12 and the frame 1 are in the vertical state after rotation, at this time, the U-shaped frame 12 contacts the magnetic blocks 17 on both sides of the frame 1, and the U-shaped frame 12 is closely attached to the magnetic blocks 17 under the action of the magnetic adsorption force of the magnetic blocks 17. At this time, the U-shaped frame 12 and the frame 1 are in a fixed connection state. At this time, the user can place the wire harness with the plug-in on the workbench and insert the plug-in of the wire harness into the plastic shell 11, so as to realize the fixation of the wire harness with the plug-in. When installing the wire harness without a plug-in, the user only needs to push the U-shaped frame 12 upward to rotate, so that the U-shaped frame 12 rotates upward against the magnetic force of the magnetic block 17 under the push of the user and separates from the magnetic block 17 until the U-shaped frame 12 flips to contact the upper end surface of the frame 1. At this time, the U-shaped frame 12 no longer blocks the fixing fork 2, so that the fixing fork 2 is exposed. Then the user controls the electromagnetic sheet 26 to be energized, so that the electromagnetic sheet 26 generates the same magnetic pole as the magnet 25, so that the magnet 25 drives the plug rod 23 fixedly connected to it to extend away from the circular groove 24 under the push of the magnetic repulsive force, so that the distance between the two plug rods 23 increases. Then the user places the wire harness between the two plug rods 23 and controls the electromagnetic sheet 26 to be powered off. At this time, the magnet 25 and the bottom of the circular groove 24 generate a magnetic adsorption force, so that the magnet 25 drives the plug rod 23 to slide into the circular groove 24, so that the two plug rods 23 clamp the wire harness, and further enables the two plug rods 23 to clamp and fix wire harnesses with different diameters, thereby improving the actual application effect of the present invention.

[0032] The lengths of the existing fixing forks 2 are not the same. This is because fixing forks 2 with different lengths can help workers assemble more conveniently. That is, the long fixing fork 2 can provide better support to help fix heavy or complex wire harnesses, while the short fixing fork 2 can improve the flexibility of assembly and is suitable for lightweight components. The setting of the rotating ring 14 is to facilitate the user to rotate the rotating ring 14, so that the rotating ring 14 can drive the fork body 22 in screw transmission connection with it to rotate relative to the rotating ring 14. Since the fork body 22 is slidably connected to the installation groove 13 through the slider 21, rotating the rotating ring 14 can drive the fork body 22 to vertically extend out of the installation groove 13, so that the length of the fork body 22 can be changed, thereby meeting the needs of the user to help fix heavy or complex wire harnesses or improve the flexibility of assembly and being suitable for lightweight components. Furthermore, the actual application effect of the present invention is further improved.
