[0027] Embodiment: as shown in Figure 1 , Figure 2 , a wire harness terminal crimping device with pressure monitoring function, comprising a supporting table 3, the top end of the supporting table 3 is provided with a feeding device 2, the top end of the supporting table 3 is fixedly connected with four fixed rods 4, the top end of the four fixed rods 4 is fixedly connected with a top plate 5, the top end of the top plate 5 is slidably penetrated by four sliding rods 6, the top end of the top plate 5 is fixedly connected with a hydraulic rod 7, the output end of the hydraulic rod 7 is fixedly connected with a second pressing plate 8, and the bottom end of the second pressing plate 8 is provided with a pressing device 1 matched with the feeding device 2.
[0028] As shown in Figure 1 , Figure 2 and Figure 3 , the pressing device 1 comprises four first sliding rods 104 fixedly connected with the bottom end of the second pressing plate 8, the bottom end of the four first sliding rods 104 is slidably penetrated by a fixed plate 103, the top end of the fixed plate 103 is fixedly connected with a first spring 101 sleeved with the side wall of the first sliding rod 104, the hydraulic rod 7 drives the second pressing plate 8 to move downward to start the crimping work of the wire harness terminal, and with the downward movement of the second pressing plate 8, the fixed plate 103 is driven to move downward by the first sliding rod 104 and the first spring 101.
[0029] As shown in Figure 1 , Figure 2 and Figure 3As shown, a pressure detection module 102 is fixedly connected to the middle of the bottom end of the fixed plate 103. By utilizing the cooperation between the second positioning module 204 and the first positioning module 107, the first pressing mold 106 and the second positioning mold 205 can be quickly aligned, improving the molding effect. Four second sliding rods 105 are fixedly connected to the bottom end of the pressure detection module 102. A pressing module is provided at the bottom end of the four second sliding rods 105. During the process of the first pressing mold 106 on the first pressure plate 108 pressing the terminal, the first pressure plate 108 will slide on the side wall of the second sliding rod 105.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a first pressure plate 108 slides through the sidewalls of four second slide rods 105. A second spring 109, which is sleeved on the sidewall of the second slide rod 105, is fixedly connected to the top of the sidewall of the first pressure plate 108. The second spring 109 cooperates with the pressure detection module 102. A first pressing mold 106 is fixedly connected to the middle of the bottom end of the first pressure plate 108. The first pressing mold 106 cooperates with the second positioning mold 205. By pressing down with the first pressing mold 106, the wire harness terminal can be crimped. A first positioning module 107 is fixedly connected to one side of the bottom end of the first pressure plate 108. The pressure generated by the first pressure plate 108 on the second spring 109 is fed back to the pressure detection module 102 for monitoring, thereby controlling the pressure generated by the hydraulic rod 7, improving the molding quality of the product, and avoiding damage during the crimping process.
[0031] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the feeding device 2 includes four positioning rods 203 that are fixedly connected to both sides of the top of the support platform 3. A slide table 202 slides through the side wall of the four positioning rods 203. A third spring 207 sleeved on the side wall of the four positioning rods 203 is fixedly connected to the bottom of the two slide tables 202. A placement plate 201 is fixedly connected between the two third springs 207. The terminals and wire harnesses to be crimped are placed into the second positioning mold 205. At this time, the cylinder 208 is opened to push the second slider 211 to slide on the third slider 216. As the second slider 211 slides to one side of the third slider 216, the first slider 210 can drive the ratchet 212 to rotate clockwise.
[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, a ratchet 212 is rotatably connected to the top of the placement plate 201, and a fixing block 213 is fixedly connected to the front side of the top of the placement plate 201. A third slider 216, which cooperates with the side wall of the ratchet 212, slides through the middle of the placement plate 201. A connecting block 217 is fixedly connected to the front end of the third slider 216. A limiting rod 215, which slides through the connecting block 217, is fixedly connected to the front end of the fixing block 213. A fourth spring 214, which is fixedly connected to the front end of the connecting block 217, is sleeved on the side wall of the limiting rod 215. When the cylinder 208 drives the second slider 211 to reset, the first slider 210 contacts the side wall of the ratchet 212 and contracts. The third slider 216 limits the position of the ratchet 212 to prevent the ratchet 212 from rotating counterclockwise.
[0033] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a third slider 216 is fixedly connected to the top of the placement plate 201. A second slider 211 is slidably fitted to the top of the third slider 216. A first slider 210, which cooperates with a ratchet 212, slides through the middle of the second slider 211. A fifth spring 218 is fixedly connected to the other end of the first slider 210. A first limiting plate 209, which is fixedly connected to the other end of the fifth spring 218, is fixedly connected to one side of the top of the second slider 211. A cylinder 208 is fixedly connected to the top of the placement plate 201. The output end of the cylinder 208 is fixedly connected to the front end of the second slider 211, so that the ratchet 212 can drive the turntable 206 to rotate synchronously clockwise, thereby moving the turntable 206 to below the first clamping mold 106 and positioning it using the second positioning module 204 to realize the cyclic feeding of the terminals.
[0034] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a turntable 206 is fixedly sleeved on the middle fixed shaft of the ratchet 212. Several second positioning molds 205 are arranged in a circumferential array at the top of the turntable 206, and the second positioning molds 205 cooperate with the first pressing mold 106. Several second positioning modules 204 that cooperate with the first positioning module 107 are provided at the top of the turntable 206, which effectively improves the working efficiency of the device and avoids workers from directly contacting the pressing area and getting injured, thus improving safety.
[0035] It should be noted that this wire harness terminal crimping device with pressure monitoring function, in use, uses a pressing device 1 to move the second pressure plate 8 downwards via a hydraulic rod 7 to begin crimping the wire harness terminals. As the second pressure plate 8 moves downwards, it drives the fixing plate 103 downwards via the first sliding rod 104 and the first spring 101. During the crimping process of the first pressing die 106 on the first pressure plate 108, the first pressure plate 108 slides against the side wall of the second sliding rod 105, and the pressure generated by the first pressure plate 108 against the second spring 109 is fed back to the pressure detection module 102 for monitoring. This allows for control of the pressure generated by the hydraulic rod 7, improving the molding quality of the product and preventing damage during the crimping process.
[0036] By setting up the feeding device 2, the terminals and wire harnesses to be crimped are placed into the second positioning mold 205. At this time, the cylinder 208 is opened to push the second slider 211 to slide on the third slider 216. As the second slider 211 slides to one side of the third slider 216, the first slider 210 drives the ratchet 212 to rotate clockwise. When the cylinder 208 drives the second slider 211 to reset, the first slider 210 contacts the side wall of the ratchet 212 and contracts. The third slider 216 limits the position of the ratchet 212 to prevent the ratchet 212 from rotating counterclockwise. This allows the ratchet 212 to drive the turntable 206 to rotate clockwise synchronously, thereby moving the turntable 206 to below the first pressing mold 106 and positioning it using the second positioning module 204. This achieves cyclic feeding of terminals, effectively improving the working efficiency of the device and avoiding injury to workers who directly contact the pressing area, thus improving safety.
[0037] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
