Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a heat shrinking device for wire harness protective sleeves. Background Technology

[0002] A wire harness is a wiring component that connects various electrical devices in a circuit. It consists of an insulating sheath, terminals, wires, and insulating wrapping materials. During the processing of a wire harness, heat shrink tubing needs to be applied to the outside and then heated to shrink it. This heat shrinking process requires heat shrinking equipment.

[0003] For example, Chinese utility model patent CN222628621U discloses a U-shaped heat shrink tubing drying machine, including a main body, a heating mechanism, and a clamping assembly. The heating mechanism includes a heating block and a hot air blower. The heating block has an installation groove for placing a wire harness, and the heating block and the hot air blower are connected. The clamping assembly includes a clamping plate disposed on the heating block, and the clamping plate has clamping blocks. The clamping blocks have clamping grooves adapted to the wire harness. When heating the heat shrink tubing on the wire harness, the wire harness is clamped in the clamping groove, and the heat shrink tubing on the wire harness is located in the installation groove. During heating, one end of the wire harness is placed in the clamping block for fixation, so that during heating, the weight of the part of the wire harness without heat shrink tubing is not too heavy, which may cause the heated position of the wire harness to shift and affect the heating efficiency of the heat shrink tubing, thereby improving the heating efficiency of the heat shrink tubing.

[0004] However, existing heat shrinking equipment for wire harness protective sleeves clamps the wire harness in the clamping groove, which does not provide high stability for the wire harness, and the wire harness is prone to displacement or jumping.

[0005] Therefore, we propose a heat-shrinkable device for wire harness protective sleeves to solve the above problems. Utility Model Content

[0008] Preferably, a second rubber pad is fixedly provided on the inner wall of the placement groove, and a first rubber pad is fixedly provided on the bottom surface of the pressure plate.

It also allows each batch of wire harnesses to extend from the center of the heating block, improving heating uniformity. Furthermore, by incorporating positioning protrusion one, positioning protrusion two, positioning protrusion three, a snap-fit ​​bracket, and a limiting baffle, the positions of the snap-fit ​​bracket and limiting baffle can be adjusted according to the length of the protective sleeve fitted onto each batch of wire harnesses.

A lead screw 12 is fixedly connected to the bottom of the rotating rod 11. The bottom of the lead screw 12 is rotatably connected to the moving block 10. A sliding groove 102 is opened on one side of the moving block 10. A lifting block 14 is slidably connected in the sliding groove 102. A threaded sleeve 141 is embedded in the lifting block 14. The threaded sleeve 141 is threadedly connected to the lead screw 12. A pressure plate 15 is fixedly connected to one side of the lifting block 14. The top surface of the fixed block 6 is fixed with multiple positioning protrusions 19, 22, and 33. There are two of each of the positioning protrusions 19, 22, and 33. A snap-fit ​​bracket 20 contacts the two positioning protrusions 19. The snap-fit ​​bracket 20 snaps into the fixed block 6. The top surface of the snap-fit ​​bracket 20 is fixed with a limiting baffle 21.

[0018] Example 2: Please see Figure 1-5This is the second embodiment of the present invention. Based on the previous embodiment, a second rubber pad 18 is fixedly provided on the inner wall of the groove 171, and a first rubber pad 16 is fixedly provided on the bottom surface of the pressure plate 15, which can improve the fixation of the wire harness.

[0019] Mounting plates 7 are fixed to both sides of the bottom of the fixing block 6, and mounting holes 71 are provided on the mounting plates 7. In use, the fixing position of the fixing block 6 can be determined by measuring the distance set by the heat shrink tubing heating machine body 1 with a ruler, and the fixing block 6 can be moved to the corresponding position and fixed by the mounting plates 7 and mounting holes 71.

[0020] The lead screw 12 is rotatably connected to the slide groove 102. The lifting block 14 is fixedly connected to the limiting block 142 on one side. The limiting groove 1021 is opened on one side of the slide groove 102. The limiting block 142 is slidably connected to the limiting groove 1021, which can limit the movement range of the lifting block 14 and improve the stability of the lifting block 14.

[0023] Please see Figure 1-5In use, this invention involves engaging the corresponding positioning protrusions on the clamping bracket 20 onto the fixing block 6 according to the length of the protective sleeve attached to the wire harness. Then, the protective sleeve attached to the end of the wire harness is placed against the limiting baffle 21 on the rubber pad 18 on the placement plate 17. This improves positioning accuracy, significantly reduces the skill requirements for operators, simplifies the operation process, and increases production efficiency. It effectively avoids common human errors such as improper sleeve installation, ensuring that the axial starting position height of the protective sleeves for all wire harnesses in the same batch is consistent. This fundamentally solves the core problems of inconsistent heat shrinkage areas, varying heat shrinkage lengths, and inconsistent product quality caused by random sleeve placement. The result is a final product with excellent consistency and stability in heat shrinkage. After placement… Rotating the rotating block 13 drives the rotating rod 11 and the lead screw 12 to rotate, causing the lifting block 14, pressure plate 15, and rubber pad 16 to move downwards. This allows the rubber pad 16 to tightly contact the surface of the wire harness, pressing and fixing the multiple wire harnesses in place, improving the fixation of the wire harnesses and making them less prone to displacement or jumping during processing. At the same time, it allows each batch of wire harnesses to extend from the middle position of the heating block 3, improving the uniformity of heating. The clamping frame 20 and the limiting baffle 21 are then removed. Next, the cylinder 8 is connected to an external power source. By starting the cylinder 8, the moving block 10 and the multiple wire harnesses being clamped are moved, allowing the protective sleeves at the ends of the multiple wire harnesses to enter the heating block 3. Hot air is blown onto the sleeves through multiple small air holes set on the inner side of the heating block 3 to heat them, which can shrink and tighten the sleeves.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
