[0021] Example: As attached Figure 1 To the attached Figure 8 As shown: The present invention provides an automobile wiring harness welding device with a fixed structure, comprising: a device frame 1; a counter frame 101 is fixedly installed at the top middle rear position of the device frame 1, a motor A102 is fixedly installed at the left middle position of the counter frame 101, the rotating shaft of the motor A102 is fixedly connected to the left position of a bidirectional screw 103, the bidirectional screw 103 is located in the interior position of the counter frame 101, the left and right sides of the interior of the counter frame 101 are respectively slidably connected to the rear position of an extension plate 104, and the rear side positions of the extension plate 104 are both provided with Threaded hole, the left and right ends of the bidirectional screw 103 are respectively located in the threaded holes of an extension plate 104, and a half gear rack 105 is fixedly installed at the front end position of each extension plate 104. The two half gear racks 105 are symmetrically designed, and the outer positions of the half gear racks 105 are slidably connected to a matching rack 106. Each matching rack 106 is provided with a gear motor group 107. The gear position of the gear motor group 107 engages with the circumferential position of the half gear rack 105, and a chuck part 108 is fixedly installed at the inner position of the front end of the matching rack 106.

[0022] Among them, a positioning frame 2 is fixedly installed at the top middle position of the device frame 1, and the top middle position of the positioning frame 2 is fixedly connected to the bottom middle position of the lifting frame 201. A motor B202 is fixedly installed at the top middle position of the lifting frame 201, and the rotating shaft of the motor B202 is provided with a thread, and the rotating shaft of the motor B202 is located in the internal position of the lifting frame 201. The internal position of the lifting frame 201 is slidingly connected to the extended position of the rear end middle position of the lifting member 203. The extended position of the lifting member 203 is provided with a threaded hole, and the rotating shaft of the motor B202 is located in the threaded hole of the lifting member 203. The front end position of the lifting member 203 is fixedly connected to the upper position of the rear end of the semicircular groove auxiliary frame 204. The upper internal position of the semicircular groove auxiliary frame 204 is fixedly installed with a motor C205, and the rotating shaft of the motor C205 is fixedly connected with a bevel gear 206.

[0023] Among them, a semi-conical gear ring 207 is rotatably connected to the lower inner position of the semicircular groove auxiliary frame 204, and plugs are provided at both ends of the semi-conical gear ring 207. The semi-conical gear ring 207 is meshed with the bevel gear 206 for transmission.

[0024] Among them, the directional frame 3 is fixedly installed at the middle position of the front end of the semi-conical gear ring 207, and the motor D301 is fixedly installed at the middle position of the top of the directional frame 3. The rotating shaft of the motor D301 is provided with a thread, and the rotating shaft of the motor D301 is located in the internal position of the directional frame 3. The internal position of the directional frame 3 is slidingly connected with the middle and rear position of the delivery frame 302. A threaded hole is provided at the middle and rear position of the delivery frame 302. The rotating shaft of the motor D301 is located in the threaded hole of the delivery frame 302. A welding machine 303 is provided at the front end position of the delivery frame 302, and the welding machine 303 is located in the middle and upper position of the two chuck parts 108.

[0025] When using: First, the device frame 1 is placed at a suitable position, and then the two sections of the wire harness to be welded are respectively placed inside a chuck 108 for clamping and fixing.

[0026] The starting motor A102 drives the bidirectional screw 103 to rotate. Since the left and right ends of the bidirectional screw 103 have opposite rotation directions and respectively cooperate with the threaded holes on the two extension plates 104, when the bidirectional screw 103 rotates, the two extension plates 104 will move closer to each other on the opposing frame 101, thereby preliminarily adjusting the distance between the two chuck parts 108, so as to facilitate the docking of the two sections of the wiring harness fixedly clamped in the two chuck parts 108. The two sections of the wiring harness will be in contact and located directly below the welding machine 303, and there is no need for manual control to limit the position of the wiring harness, thereby improving safety.

[0027] Start the gear motor group 107 and its gears mesh with the circumferential surface of the half gear frame 105, driving the matching frame 106 to slide on the outside of the half gear frame 105. The chuck member 108 at the front end of the matching frame 106 moves with the matching frame 106 and adjusts its position according to the center position of the half gear frame 105. The position angle of the chuck member 108 is adjusted to achieve the adjustment of the oblique welding of the wire harness.

[0028] After the welding position of the wire harness is determined, start the motor B202, and the lifting member 203 is driven to slide up and down inside the lifting frame 201 by cooperating with the rotating shaft of the motor B202 and the threaded hole at the extended position of the lifting member 203, thereby realizing the vertical position adjustment of the semicircular groove auxiliary frame 204 and the directional frame 3 as a whole, until the bottom center position of the semicircular groove auxiliary frame 204 is located in the middle position of the wire harness welding position clamped by the two chuck members 108, and then start the welding machine 303 to perform welding operations on the fixed wire harness. Since the wire harness is firmly fixed and the welding position is accurate, the welding quality can be guaranteed to be stable and reliable.

[0029] Because motor C205 is installed above the interior of semicircular groove auxiliary frame 204, its rotating shaft is fixedly connected to bevel gear 206. Bevel gear 206 is meshed with semi-conical gear ring 207 for transmission. Semi-conical gear ring 207 has plugs at both ends and can rotate below the interior of semicircular groove auxiliary frame 204.

[0030] When the bevel gear 206 of the motor C205 rotates, it drives the bevel gear 206 to rotate inside the semicircular groove auxiliary frame 204, and then drives the semi-bevel gear ring 207 to rotate, thereby driving the front-end directional frame 3 delivery frame 302 and the welding machine 303 to rotate, so as to adjust the angle of the welding machine 303. The welding machine 303 is used to adjust the circumferential rotation of the wiring harness welding position fixed by the two chuck parts 108 to avoid the situation where the welding position is single and the welding is prone to loose welding and desoldering.

[0031] When the motor D301 rotates, the delivery rack 302 is driven to slide back and forth inside the directional rack 3 through the threaded transmission, thereby adjusting the distance between the welding position of the welding machine 303 and the center position of the semicircular groove auxiliary rack 204. During the process of wire harness welding, the spacing of the welding positions can be appropriately adjusted to avoid the welding machine 303 contacting the welding position or the welding position being too far away.

[0032] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. The protection scope of the present disclosure should be based on the protection scope of the claims.
