Description

Technical Field

[0001] This utility model relates to the field of wire harness welding technology, and specifically to a wire harness clamping welding fixture. Background Technology

[0002] A wire harness is a wiring component in a circuit that connects various electrical devices. It consists of an insulating sheath, terminals, wires, and insulating wrapping material. Wire harnesses are widely used in various precision electronic devices, such as automotive circuits, computer motherboard circuits, and household appliance circuits.

[0003] The ends of wire harnesses are usually welded with terminals to meet normal usage requirements. Currently, the ends of the wire harness and the terminals are often placed manually in the preset positions on the welding station of the ultrasonic welding machine. However, due to the flexibility of the wire harness material, the ends of the wire harness will shake during the manual grasping and placement process, making it difficult to place the wire harness in the preset position on the welding station. This results in inaccurate positioning of the ends of the wire harness. Furthermore, the lack of a fixing mechanism for the wire harness during welding leads to instability, which can easily result in unreliable welding and thus affect the welding quality.

A conveying assembly capable of fixing the wire harness to be welded is installed on one side of the two sets of clamping assemblies.

[0007] This application uses two sets of clamping components symmetrically installed on both sides of the workbench to clamp the wire harness to be welded.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] Reference Figure 1 and Figure 2 A wire harness clamping and welding fixture includes a worktable 1, side plate 2, side plate 3, clamping component 4, clamping component 5, conveying assembly 6, driving component 2 7, dust removal component 8, and driving component 9. The side plates 2 and 3 are located on the top sides of the worktable 1 (here, the direction is...). Figure 1 (Based on the standard); both clamping member 4 and clamping member 5 are provided in two sets, both located between side plate 2 and side plate 3; driving member 7 is installed on side plate 3 and is used to drive clamping member 5 to move, driving member 9 is installed on side plate 2 and is used to drive clamping member 4 to move; and conveying assembly 6 is provided in two sets, respectively located outside clamping member 4 and clamping member 5.

[0043] Reference Figure 3 Side plate 1 2 and side plate 2 3 are distributed perpendicularly to the worktable 1. Two sets of motor sliding grooves 21 are symmetrically opened on side plate 1 2, and drive component 1 9 is installed on side plate 1 2.

[0044] Furthermore, refer to Figure 3 and Figure 4 The driving component 9 includes a motor 91, a guide rail 93, a rack 94, a slider 95, and a gear 96. The motor 91 is installed at the middle position of the outer side of the side plate 2, between the two motor sliding grooves 21. The gear 96 is installed at the middle position of the inner side of the side plate 2 (i.e., the side facing the middle of the worktable). The output end of the motor 91 is connected to the gear 96. Two racks 94 are meshed on the upper and lower sides of the gear 96. The two racks 94 slide on the inner side of the side plate 2. One end of the two racks 94 is connected to the mounting plate 42 in the two clamping components 4 through connecting rods. A guide rail 93 is also provided on the inner side of the side plate 2 and outside the two racks 94. The racks 94 are slidably connected to the guide rail 93 through the slider.

[0045] Therefore, when motor 391 is working, it can drive gear 196 to rotate, which in turn drives two racks 194 to move. The two racks 194 drive two clamping parts 14 to move in opposite directions through the connecting rod. When the two clamping parts 14 drive the wire harness 10 to be welded to move in opposite directions to the middle position of the worktable 1, it is the welding position.

[0046] Reference Figure 4 and Figure 5 The upper and lower parts of the second side plate 3 are provided with slider grooves 31. The second driving component 7 is installed on the side of the second side plate 3 facing away from the middle position of the worktable 1. The second driving component 7 includes a second motor 71, a second rack 72, a second slider 73, a second guide rail 74 and a second gear 75. The second gear 75 is installed at the middle position of the outer side of the second side plate 3. The output end of the second motor 71 is connected to the second gear 75 for transmission. The second motor 71 is installed on the second side plate 3 through a motor fixing bracket. The upper and lower sides of the second gear 75 are meshed with two second racks 72. The two second racks 72 are slidably connected to the second side plate 3. One end of the two second racks 72 is slidably connected to the two slider grooves 31 through the second sliders 73. The two second sliders 73 pass through the corresponding slider grooves 31 and are connected to the second clamping component 5. The second guide rail 74 is also provided on the outer side of the second side plate 3 and on the outer side of the two second racks 72. The second racks 72 are slidably connected to the second guide rail 74 through the sliders.

[0047] Therefore, when motor 2 71 is working, it can drive gear 2 75 to rotate, which in turn drives two racks 2 72 to move. The two racks 2 72 drive two clamping parts 2 5 to move in opposite directions through connecting rods. When the two clamping parts 2 5 drive the wire harness 10 to be welded to move in opposite directions to the middle position of the worktable 1, it is the welding position.

[0048] It should be noted that clamping component 4 and clamping component 5 on the same side are on the same horizontal line. Both sets of clamping components 4 and clamping components 5 move at the same time. The clamping components 4 and clamping components 5 on the same side jointly clamp the wire harness 10 to be welded and move it to the welding position for welding.

[0049] Reference Figure 3 Two sets of clamping components 4 are symmetrically arranged. The two sets of clamping components 4 are respectively installed at both ends of the side plate 2. The two sets of clamping components 4 can be driven to move in opposite directions or towards each other simultaneously by the driving component 9. Specifically, the clamping component 4 includes a motor 41, a mounting plate 42, a guide post 43, a connecting screw 44, a slide table 45, a plug screw 46, a spring 47, and a clamping plate 48. The mounting plate 42 is connected to the corresponding rack 94 through a connecting rod. When the rack 94 moves, it can drive the mounting plate 42 to move. The motor 41 is installed on the side of the mounting plate 42 facing the side plate 2, and the connecting screw 44 is installed on the side of the mounting plate 42 facing away from the side plate 2. The output end of the motor 41 can be connected to the connecting screw 44, and the other end of the connecting screw 44 is connected to the slide table 45. Therefore, the motor 41 can drive the connecting screw 44 to rotate, thereby driving the slide table 45 to move along the connecting screw 44.

[0050] Furthermore, the mounting plate 42 is provided with two guide posts 43 on the side facing away from the side plate 2 and located outside the connecting screw 44. The guide posts 43 can pass through the slide table 45, so that the slide table 45 can move along the guide posts 43 when it moves. The guide posts 43 are arranged in parallel with the connecting screw 44.

[0051] Furthermore, a number of locking screws 46 are installed on the slide table 45. The end of the locking screw 46 facing the side plate 3 is connected to a clamping plate 48. A spring 47 is also sleeved on the outside of the locking screw 46 between the clamping plate 48 and the slide table 45.

[0052] The principle here is as follows: The rotation of motor 41 drives the connecting screw 44 to rotate, which in turn causes the slide 45 to move up and down along the direction of the guide post 43 and the connecting screw 44 (here, the up and down positions are...). Figure 3 (For reference), then drive the clamping plate 48 and cooperate with the clamping plate 52 (described in detail below) in the clamping member 25 to squeeze and fix the wire harness 10. When the motor 3 91 works, it can drive the gear 96 to rotate, which in turn drives the two racks 94 to move. The two racks 94 drive the two mounting plates 42 to move towards or away from each other through the connecting rod. When the two mounting plates 42 drive the wire harness 10 to be welded to move towards each other to the middle position of the worktable 1, it is the welding position. The clamping member 25 fixes the position of the wire harness, and the welding work can be carried out afterwards.

[0053] Reference Figure 5The clamping component 2 5 includes a wire clamping plate fixing frame 51 and a wire clamping plate 2 52. The side of the wire clamping plate fixing frame 51 facing the side plate 2 3 is connected to the corresponding rack 2 72 via a connecting rod. Several wire clamping plates 2 52 are installed on the other side of the wire clamping plate fixing frame 51. The number of wire clamping plates 2 52 is the same as the number of wire clamping plates 1 48, and they correspond one-to-one. The wire clamping plates 1 48 can clamp a cable exactly between themselves and the wire clamping plates 2 52. The position of the wire clamping plates 1 48 can be adjusted by the motor 1 41, thereby adjusting the distance between the wire clamping plates 1 48 and the wire clamping plates 2 52. The adjustment can be made according to the needs of the cable.

[0054] It should be noted that both the inner sides of the cable clamping plate 48 and the cable clamping plate 52 are provided with grooves for clamping cables.

[0055] Reference Figure 3 The conveying assembly 6 includes a fixed plate 61, a sliding plate 62, and a second screw 63. The fixed plate 61 has an "L" shape and is installed on the workbench 1 and behind the wire clamping plates 48 and 52. The sliding plate 62 is slidably connected to the fixed plate 61 at the wire clamping position of the wire clamping plates 48 and 52. The second screw 63 is installed on the sliding plate 62, and the wire harness can be fixed by squeezing the wire harness through the second screw 63.

[0056] Reference Figure 2 A dust removal component 8 is installed at the top center of side plate 2 3 and directly above the welding position. The dust removal component 8 can be a dust removal pump for dust removal during welding.

[0057] The specific operating principle of this application is as follows:

[0058] During operation, firstly, the motor 41 rotates the connecting screw 44. Under the push of the screw, the clamping plate 48 is pushed to the appropriate position. Then, the wire harness is passed through the conveying mechanism 6 and the conveying mechanism 6 clamps the wire harness. Then, the wire harness is fixed in the middle groove of the clamping plate 48 and the clamping plate 52 on both sides. Pull the end screw 46 to insert the wire harness. Loosen the screw 46. The clamping plate 48 will interact with the clamping plate 52 on the other side under the action of the spring force, clamping and fixing the wire harness.

[0059] Then, by using motors 71 and 91 on both sides to rotate the corresponding gears, the corresponding racks are driven, so that the wire harnesses between clamping plates 48 and 52 on both sides come closer to each other and stop at the appropriate position, and then the personnel perform welding.

[0060] After welding is completed, rotate motor 41 to separate the clamping plates and remove the welded wire harness.

[0061] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
