Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts manufacturing, and in particular to a simple welding fixture for wire harness brackets. Background Technology
[0002] In the production of automotive wiring harness brackets, small-batch welding modifications are often required to meet specific needs. The welding quality of the wiring harness brackets directly affects their subsequent assembly accuracy and operational stability; therefore, strict requirements are placed on the dimensional accuracy and appearance quality of the welded components.
[0003] In the existing technology, there is a lack of special tooling for this type of small-batch welding modification, and operators usually use manual hand-held part positioning for welding.
[0004] This method has the following drawbacks: First, the lack of a fixed reference structure makes it impossible to provide stable support, resulting in large positioning deviations of parts and difficulty in achieving the required dimensional accuracy after welding. Secondly, without a reliable clamping mechanism, the parts are prone to displacement due to high temperature or external force during the welding process, which not only produces appearance defects such as weld beads and deformation, but also requires repeated adjustments and rework. Third, the operation is inefficient. Manual positioning and clamping are time-consuming and require multiple people to assist, which cannot meet the cycle requirements of small-batch modification projects. At the same time, the labor cost and the scrap rate of parts are relatively high. Utility Model Content
[0005] The purpose of this utility model is to provide a simple welding fixture for wire harness brackets to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a simple welding fixture for wire harness brackets, including a base, a fixing unit installed on the top of the base, and a clamping block provided on the side of the fixing unit. The clamping block is connected to a clamp, and the clamp is used to drive the clamping block to move. The fixing unit includes a positioning plate and a fixing plate and a shaping plate fixedly installed above the positioning plate. The shaping plate is installed at an angle at the end of the fixing plate, and the clamping block is set in an L shape. When the clamping block moves toward the fixing plate and the shaping plate, it can tightly clamp the wire harness bracket between the clamping block and the fixing plate and the shaping plate.
[0007] Preferably, a support block is fixedly installed between the bottom of the positioning plate and the base, and a flange is provided on the side of the positioning plate near the clamp.
[0008] Preferably, the connection between the positioning plate and the flange is chamfered.
[0009] Preferably, the clamping block consists of a transverse portion and a longitudinal portion fixedly installed at the end of the transverse portion.
[0010] Preferably, the lower surface of the clamping block contacts the upper surface of the positioning plate without squeezing.
[0011] Preferably, the clamp includes a fixed base and a rotating base and a guide sleeve installed on both sides above the fixed base. A first rotating profile is rotatably connected to the outer side of the rotating base. A movable rod is movably inserted into the inside of the guide sleeve. One end of the movable rod is fixedly connected to the clamping block, and the other end of the movable rod is rotatably connected to a second movable profile. The other end of the second movable profile is rotatably connected to the outer side of the first rotating profile.
[0012] Preferably, a handle is fixedly connected to the end of the first rotating profile away from the rotating seat.
[0013] The technical effects and advantages of this utility model are as follows: The positioning plate provides a horizontal reference surface for the part. The fixing plate and the shaping plate limit the part from the side and the inclined direction, respectively. The contouring structure of the shaping plate can perfectly adapt to the shape of the part to be welded, avoiding the part from being misplaced. At the same time, the horizontal and vertical parts of the L-shaped clamping block can clamp the part from two vertical directions. With the stable clamping force of the clamp drive, it can effectively prevent the part from shifting during the welding process, ensure that the welding dimensional accuracy meets the requirements, and reduce appearance defects such as weld beads and deformation.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This utility model provides, for example Figures 1-3 The simple welding fixture for the wire harness bracket shown includes a base 1, a fixing unit 2 installed on the top of the base 1, and a clamping block 3 provided on the side of the fixing unit 2. The clamping block 3 is connected to a clamp 4, and the clamping block 3 is moved by the clamp 4. The fixing unit 2 includes a positioning plate 21 and a fixing plate 22 and a shaping plate 23 fixedly installed above the positioning plate 21. The shaping plate 23 is installed at an angle at the end of the fixing plate 22, and the clamping block 3 is set in an L shape. When the clamping block 3 moves toward the fixing plate 22 and the shaping plate 23, it can tightly clamp the wire harness bracket between the clamping block 3 and the fixing plate 22 and the shaping plate 23.
[0018] Furthermore, a support block is fixedly installed between the bottom of the positioning plate 21 and the base 1, and a flange 211 is provided on the side of the positioning plate 21 near the clamp 4.
[0019] Furthermore, the connection between the positioning plate 21 and the flange 211 is chamfered.
[0020] Furthermore, the clamping block 3 consists of a transverse portion 31 and a longitudinal portion 32 fixedly installed at the end of the transverse portion 31.
[0021] The positioning plate 21 provides a horizontal reference surface for the part. The fixing plate 22 and the shaping plate 23 limit the part from the side and the inclined direction, respectively. The contouring structure of the shaping plate 23 can be fully adapted to the shape of the part to be welded, avoiding the part from being misplaced. At the same time, the horizontal part 31 and the vertical part 32 of the L-shaped clamping block 3 can clamp the part from two vertical directions. With the stable clamping force driven by the clamp 4, it can effectively prevent the part from shifting during the welding process, ensure that the welding dimensional accuracy meets the requirements, and reduce appearance defects such as weld beads and deformation.
[0022] Furthermore, the lower surface of the clamping block 3 contacts the upper surface of the positioning plate 21 without squeezing.
[0023] Furthermore, the clamp 4 includes a fixed base 41 and a rotating base 42 and a guide sleeve 43 installed on both sides above the fixed base 41. The outer side of the rotating base 42 is rotatably connected to a first rotating profile 44. The guide sleeve 43 is movably inserted into a movable rod 45. One end of the movable rod 45 is fixedly connected to the clamping block 3, and the other end of the movable rod 45 is rotatably connected to a second movable profile 46. The other end of the second movable profile 46 is rotatably connected to the outer side of the first rotating profile 44.
[0024] Furthermore, a handle 47 is fixedly connected to the end of the first rotating profile 44 away from the rotating seat 42.
[0025] Operate the handle 47 of the clamp 4, rotate the first rotating profile 44 upward, and drive the movable rod 45 to extend out of the guide sleeve 43 through the second movable profile 46, so that the clamping block 3 is away from the fixed unit 2, and the tooling is in the clamping state.
[0026] The two wire harness bracket parts to be welded are placed on the positioning plate 21 of the fixing unit 2 respectively: one side of one part is attached to the vertical surface of the fixing plate 22, and the other side is close to the contour surface of the molding plate 23. The inclined structure of the molding plate 23 is used to achieve precise positioning of the part; the other part is placed on the side of the positioning plate 21 near the clamping block 3, initially aligned with the welding position, and the placement position can be quickly calibrated with the help of the flange 211 of the positioning plate 21.
[0027] When the part is clamped and fixed, the operator rotates the handle 47 of the clamp 4 downwards. The handle 47 drives the first rotating profile 44 to rotate clockwise around the rotating seat 42. The first rotating profile 44 pulls the second movable profile 46, causing the second movable profile 46 to drive the movable rod 45 to move axially towards the fixing unit 2 within the guide sleeve 43. The movable rod 45 pushes the clamping block 3 to move synchronously until the horizontal part 31 of the clamping block 3 presses against the horizontal end of the part and the vertical part 32 fits against the vertical end of the part, clamping the two parts together between the clamping block 3 and the fixing plate 22 and the molding plate 23, thus completing the part fixing.
[0028] While keeping the parts clamped, welding is performed on the butt joint of the two parts. After welding, the handle 47 is turned upwards, the first rotating profile 44 rotates in the opposite direction, and the second movable profile 46 drives the movable rod 45 to move in the opposite direction, the clamping block 3 moves away from the fixed unit 2 and the parts are released. Finally, the operator removes the welded wire harness bracket from the positioning plate 21, completing a single welding operation, and the fixture can enter the welding cycle of the next part.
[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
