Description

Technical Field

[0001] This utility model relates to the field of wire harness crimping machines, and in particular to a crimping mechanism for a wire harness crimping machine. Background Technology

[0002] A wire harness crimping machine is a high-efficiency device used for the precise connection of wires to terminals or connectors. It is widely used in the automotive, electronics, communications and new energy fields. Its core principle is to use mechanical external force to tightly bond the terminals and wires, forming reliable electrical conduction and mechanical strength, replacing the traditional welding process, and has the advantages of high efficiency and strong stability.

[0003] Chinese patent CN221574501U discloses a highly stable wire harness terminal crimping machine. By using a slider to drive a sliding rod, a scraper scrapes the surface of the placement block, thereby preventing copper wires from sticking to the surface of the placement block. This avoids the sticky copper wires affecting the normal use of the device and eliminates the need for workers to clean the sticky copper wires, saving cleaning operations and increasing the work speed of the workers.

[0004] In the aforementioned patent, manual operation is required to stabilize the wire harness for crimping the terminals. However, manual operation can lead to errors such as incorrect placement of the terminals inside the crimping machine, resulting in crimping failure. Additionally, the lack of mechanical fixation of the wire harness leads to poor stability during crimping and inconsistent product quality. Therefore, a wire harness crimping machine mechanism is needed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a wire harness crimping machine crimping mechanism to solve the problems mentioned in the background art, such as the lack of mechanical fixation of wire harnesses, poor stability during wire harness crimping, and inconsistent product quality.

[0009] Preferably, the top plate has an arc-shaped groove inside, and a sliding groove is provided below the arc-shaped groove, which is connected to the bottom of the top plate.

[0010] Preferably, the clamping assembly includes a crossbar, a limiting rod, a stabilizing wheel, a slider, a drive shaft, and a gear. The limiting rod and the drive shaft are located at the two ends of the crossbar, and the stabilizing wheel is mounted on the limiting rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses two clamping components above the top plate. The wire harness body, with one end containing the terminal, passes through these components and moves between the upper and lower molds. When the connecting piece at the terminal end contacts the positioning block on the lower mold, the electric telescopic rod is activated, moving the rack. The rack then rotates two gears simultaneously, causing the two stabilizing wheels to move towards the center and clamp the wire harness body. Next, the hydraulic cylinder is activated to crimp the wire harness. Finally, the electric telescopic rod moves the rack in the opposite direction, displacing the two stabilizing wheels. At this point, the crimped wire harness body can be removed. The two stabilizing wheels position the wire harness body, preventing misalignment during crimping and improving the stability of the crimping operation. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] 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.

[0024] Please see Figure 1-5 In this utility model, a wire harness pressing machine pressing mechanism includes a worktable 1 and a top plate 2. The top plate 2 is located above the worktable 1 and is connected to the worktable 1 by a column 203. An electric telescopic rod 6, a rack 7 and a fixing plate 8 are provided between the top plate 2 and the worktable 1. A clamping assembly 3 is provided above the top plate 2. A wire harness body 4 is placed between the two clamping assemblies 3. A bracket 5 is provided on one side of the top plate 2. An upper mold 502 and a lower mold 503 are arranged between the bracket 5 and the worktable 1 from top to bottom.

[0025] The wire harness product includes a wire harness body 4 and a terminal 401. One end of the wire harness body 4 is exposed. The exposed end of the wire harness body 4 is located inside the terminal 401. The terminal 401 is placed between the upper mold 502 and the lower mold 503 before processing.

[0026] Example 1: Please refer to Figure 1-5 In this embodiment of the utility model, a wire harness crimping machine crimping mechanism has a collar 402 and a connecting piece 403 located at both ends of the exposed end of the terminal 401. Both the collar 402 and the connecting piece 403 are connected to the terminal 401. Before crimping, the terminal 401 and the wire harness body 4 need to be connected in advance through the collar 402. After the wire harness body 4 is crimped, it is connected to the equipment through the connecting piece 403.

[0027] A hydraulic cylinder 501 is installed on the top of the bracket 5. A piston rod is installed inside the hydraulic cylinder 501. One end of the piston rod passes through the bracket 5 and connects to the upper mold 502. The upper mold 502 has an inverted U-shaped structure. A positioning block 5031 is installed on the top of the lower mold 503. After the end of the wire harness body 4 containing the terminal 401 passes through the two clamping components 3, it moves between the upper mold 502 and the lower mold 503. When the connecting piece 403 at one end of the terminal 401 contacts the positioning block 5031 on the lower mold 503, the wire harness body 4 can no longer move. The terminal 401 is now completely located between the upper mold 502 and the lower mold 503, realizing the initial positioning of the wire harness body 4. At the same time, since the terminal 401 has a flat bottom structure, the bottom of the terminal 401 is always in contact with the top of the lower mold 503, thereby preventing the terminal 401 from rotating during crimping.

[0028] Example 2: Please refer to Figure 1-5The difference from Embodiment 1 is that the top plate 2 has an arc-shaped groove 201 inside, and a sliding groove 202 is provided below the arc-shaped groove 201, which is connected to the bottom of the top plate 2.

[0029] The clamping assembly 3 includes a crossbar 301, a limiting rod 302, a stabilizing wheel 303, a slider 304, a drive shaft 305, and a gear 306. The limiting rod 302 and the drive shaft 305 are located at opposite ends of the crossbar 301. The stabilizing wheel 303 is mounted on the limiting rod 302. The upper end of the limiting rod 302 is axially connected to the crossbar 301, and the lower end of the limiting rod 302 passes through the arc-shaped groove 201 and is connected to the slider 304. The slider 304 is located inside the groove 202. The upper end of the drive shaft 305 is connected to the crossbar 301. 1. The lower end of the drive shaft 305 is connected to the gear 306, which meshes with the rack 7. The electric telescopic rod 6 is located below the rack 7 and is fixed on the worktable 1. One end of the rack 7 is provided with a baffle 702, and a limit plate 701 is provided on the top of the rack 7. The extended end of the electric telescopic rod 6 is connected to the baffle 702. The upper end of the fixing plate 8 is connected to the lower part of the top plate 2. The fixing plate 8 is provided with a slot 801, and the limit plate 701 is located inside the slot 801.

[0030] When terminal 401 is completely positioned between upper mold 502 and lower mold 503, electric telescopic rod 6 extends, driving rack 7 to move. Rack 7 then drives two gears 306 to rotate simultaneously, causing two stabilizing wheels 303 to move towards the center and clamp the wire harness body 4. This achieves secondary positioning of the wire harness body 4, thereby avoiding misalignment during crimping, improving the stability of the crimping operation, and ensuring the uniformity of product quality.

[0031] The working principle of this utility model is as follows:

[0032] After the end of the wire harness body 4 containing the terminal 401 is passed through the two clamping components 3, it moves between the upper mold 502 and the lower mold 503. When the connecting piece 403 at one end of the terminal 401 contacts the positioning block 5031 on the lower mold 503, the wire harness body 4 can no longer move, thus achieving the initial positioning of the wire harness body 4. Then, the electric telescopic rod 6 is activated, causing the two stabilizing wheels 303 to move towards the center simultaneously and clamp the wire harness body 4, thus achieving the secondary positioning of the wire harness body 4. After that, the hydraulic cylinder 501 drives the upper mold 502 to descend and perform the crimping operation on the wire harness body 4. After completion, the hydraulic cylinder 501 and the electric telescopic rod 6 are reset in sequence. At this time, the crimped wire harness body 4 can be taken out and put back into the wire harness product to be crimped. Repeating the above operation can achieve a highly stable continuous crimping operation, thereby improving product production efficiency while ensuring product quality.
