Description

Technical Field

[0001] The invention relates to the field of mold clamping mechanisms, in particular to a mold clamping mechanism for a U-shaped terminal riveting machine for wire harness production. Background Art

[0002] The U-shaped terminal riveting machine in the production of wire harnesses is a key equipment commonly used in the manufacture and assembly of wire harnesses. It is mainly used to firmly rivet the U-shaped terminal to the wire harness to achieve electrical connection. The U-shaped terminal riveting machine uses riveting technology to connect the U-shaped terminal with the wires or cables in the wire harness. During the riveting process, the power system of the riveting machine (such as a cylinder) pushes the riveting head to apply pressure to the U-shaped terminal, causing it to deform and tightly wrap the wire, thereby achieving the purpose of connection.

[0003] One of the core components of the U-shaped terminal riveting machine in the production of wire harnesses is the clamping mechanism, which is responsible for accurately and firmly connecting the U-shaped terminal to the wire harness or other components, placing the U-shaped terminal in the corresponding position of the lower die, and adjusting the position of the wire harness or other components to ensure that they are accurately docked with the U-shaped terminal. The drive device is started, driving the upper die to descend rapidly along the guide mechanism until it is in close contact with the lower die. In this process, the upper die and the lower die together form a closed riveting space, pressing the U-shaped terminal to the wire harness or other components tightly together. In the clamping state, the riveting machine firmly connects the U-shaped terminal to the wire harness or other components through specific riveting methods (such as rotary riveting, pressure riveting, etc.).

[0004] In the prior art, when the upper mold of the U-shaped terminal riveting machine in the production of wire harnesses is offset when pressing down the U-shaped terminal and the wire harness, the offset of the upper mold will cause the contact area between the U-shaped terminal and the wire harness to decrease, and the connection strength after riveting will decrease, resulting in loosening or falling off, affecting the reliability and durability of the product.

[0027] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] For example, see Figure 1 - Fig. 9 The present invention provides a technical solution of a clamping mechanism for a U-shaped terminal riveting machine for wire harness production: the outer wall of the top of the operating table is fixedly connected with a placing plate 2, the outer wall of the top of the placing plate 2 is fixedly connected with a fixing shell 4, the outer wall of the bottom of the push rod 12 is fixedly connected with a plug-in shell 3, the outer wall of the top of the operating table is fixedly connected with a fixing column 9 on the side close to the placing plate 2, the position of the fixing column 9 is aligned with the position of the lower mold shell 5, the lower part of the inside of the fixing column 9 is fixedly connected with a reset spring 91, the outer wall of the top of the reset spring 91 is fixedly connected with a slide plate 95, the outer walls on both sides of the fixing column 9 are provided with strip grooves, the inside of the strip grooves and the outer wall of the slide plate 95 are aligned with each other. Sliding connection, the outer walls of both ends of the slide plate 95 are fixedly connected with support plates 93, the outer walls of the tops of the two support plates 93 are fixedly connected with rubber pads, the outer walls of the bottoms of the two support plates 93 are fixedly connected with gravity blocks 94, the outer walls of the tops of the support plates 93 are in movable contact with the outer walls of the bottoms of the U-shaped terminal body 6, the outer wall of the top of the slide plate 95 is fixedly connected with the support block 92, the outer wall of the fixed column 9 is provided with a through hole above the strip groove, and the insides of the two through holes are movably plugged with pressure plates 96, and the opposite sides of the two pressure plates 96 are fixedly connected with return springs three 97, and the outer walls of the opposite sides of the two pressure plates 96 are in movably contact with the outer wall of the support block 92.

[0029] By extending the pressing plate 96 to both sides through the through hole on the fixing column 9 and thereby fixing it to the top of the other side of the U-shaped terminal body 6, the U-shaped terminal body 6 can be fixed inside the lower mold shell 5, thereby avoiding the movement of the U-shaped terminal body 6 when the wiring harness is placed inside the U-shaped terminal body 6 for tight pressing, resulting in unstable contact between the wiring harness and the U-shaped terminal body 6. This correspondingly increases the stability of the U-shaped terminal body 6 and the wiring harness during the pressing process, prevents poor riveting due to offset, and reduces waste of production costs.

[0030] Embodiment 2, on the basis of embodiment 1, the U-shaped terminal riveting machine body 1 comprises: a device shell 11 and a push rod 12, the lower part of the interior of the device shell 11 is slidably connected to the outer wall of the push rod 12, an operating table is arranged at the lower part of the interior of the U-shaped terminal riveting machine body 1, the interiors of the two fixed shells 4 are rotatably connected with a rotating rod 41, the outer wall of the plug-in shell 3 is movably plugged with a connecting sleeve 71, the outer wall of the bottom of the connecting sleeve 71 is fixedly connected with the upper mold shell 7, the outer wall of the connecting sleeve 71 is provided with a square hole, and the inside of the square hole is movably plugged with the outer wall of the limiting rod 35.

[0031] By limiting the movement direction of the rotating rod 41 and the limit plate 31, the stability of the upper mold shell 7 driven by the limit plate 31 can be increased, thereby avoiding the movement trajectory of the upper mold shell 7 to be offset when the upper mold shell 7 presses the U-shaped terminal body 6 and the wiring harness downward. Accordingly, by limiting the movement trajectory of the upper mold shell 7, it is ensured that the U-shaped terminal body 6 and the wiring harness are riveted at a predetermined position, thereby preventing offset or misalignment during the riveting process and ensuring the accuracy of the crimping position. The U-shaped terminal body 6 is tightly connected to the wiring harness through the riveting process to form a stable electrical connection point. This connection method can ensure the effective transmission of current and signals in the wiring harness and prevent circuit breaks or poor contact caused by unreliable connections.

[0032] Embodiment 3, on the basis of embodiment 2, the outer wall of the top of the placing plate 2 is fixedly connected to the lower mold shell 5, the outer wall of the top of the placing plate 2 is provided with slots 81 on both sides close to the lower mold shell 5, the lower parts of the two slots 81 are fixedly connected with buffer elastic blocks 82, the outer wall of the top of the buffer elastic block 82 is fixedly connected with the buffer plate 8, the outer wall of the buffer plate 8 is slidably connected to the inside of the slot 81, and the lower mold shell 5 is movably contacted with the U-shaped terminal body 6.

[0033] The U-shaped terminal body 6 is riveted by the upper mold shell 7, so that the U-shaped terminal body 6 and the wiring harness are tightly combined. The introduction of the buffer elastic block 82 effectively alleviates the direct impact of the upper mold shell 7 on the U-shaped terminal body 6 and the wiring harness. During the riveting process, the buffering effect can protect the U-shaped terminal body 6 and the wiring harness from damage, and also helps to increase the service life of the mold.

[0034] Embodiment 4, on the basis of embodiment 3, a strip groove is provided in the middle of the top of the lower mold shell 5, a conductive rubber 51 is fixedly connected inside the strip groove, a groove is provided at the bottom of the conductive rubber 51, a metal sheet 52 is fixedly connected inside the groove, a grounding wire 53 is fixedly connected to the outer wall of the bottom of the metal sheet 52, and the outer wall of the grounding wire 53 passes through the bottom of the U-shaped terminal riveting machine body 1 and contacts the ground.

[0035] Through the elasticity of the conductive rubber 51 itself, the conductive rubber 51 can always maintain contact with the U-shaped terminal body 6, avoiding static electricity generated by friction and contact between the materials during the pressing of the U-shaped terminal body 6 and the wiring harness. Accordingly, the static electricity generated during the pressing of the U-shaped terminal body 6 and the wiring harness is discharged, preventing electric shock, sparks, etc. caused by static electricity accumulation, thereby improving personnel safety.

[0036] Embodiment 5, on the basis of embodiment 4, a spring block 32 is fixedly connected to the upper part of the interior of the plug-in shell 3, a push block 34 is fixedly connected to the outer wall at the bottom of the spring block 32, the bottom of the push block 34 is an inclined surface, a plurality of slide grooves 33 are provided on the outer wall of the plug-in shell 3, the outer wall of the plug-in shell 3 is slidably connected to the limit plate 31, the outer wall of the limit plate 31 is in active contact with the outer wall of the rotating rod 41, the outer wall of the push block 34 is fixedly connected to a connecting block 36, the outer walls of one end of the plurality of connecting blocks 36 are fixedly connected to the inner wall of the limit plate 31, the outer wall of the connecting block 36 is slidably connected to the inner wall of the slide groove 33, a reset elastic block 37 is fixedly connected to the interior of the plug-in shell 3, the outer walls of the plurality of reset elastic blocks 37 are fixedly connected to the limit rod 35, the outer wall of the limit rod 35 is slidably connected to the outer wall of the plug-in shell 3.

[0037] By pressing the spring block 32 upwards and away from one side of the limit rod 35 through the push block 34, the limit rod 35 can be pushed into the interior of the plug-in shell 3 under the action of the reset elastic block 37, thereby releasing the fixation of the limit rod 35 and the connecting sleeve 71. At this time, the connecting sleeve 71 and the upper mold shell 7 can be removed from the plug-in shell 3 to complete the replacement of the upper mold shell 7. This operation is simple and quick, which is convenient for the operator to quickly replace the upper mold shell 7, thereby reducing the length of equipment downtime.

[0038] Embodiment 6, on the basis of embodiment 5, two sides of the outer wall of the limit plate 31 are provided with a second slide groove 311, the inside of the second slide groove 311 is slidably connected with a U-shaped rod 313, one side of the inside of the second slide groove 311 is fixedly connected with a return spring 1 312, the outer wall of one end of the return spring 1 312 is fixedly connected to the outer wall of one side of the U-shaped rod 313, and the inner wall of the U-shaped rod 313 is in active contact with the outer wall of the limit rod 35.

[0039] By making the U-shaped rod 313 contact with the limit rod 35, the stability of the limit plate 31 on the plug-in shell 3 can be increased, and the limit plate 31 is prevented from sliding on the rotating rod 41, causing the limit plate 31 to move on the plug-in shell 3, resulting in an unstable connection between the plug-in shell 3 and the connecting sleeve 71. Correspondingly, the connection stability between the connecting sleeve 71 and the plug-in shell 3 is increased, thereby improving the working efficiency of the upper mold shell 7.

[0040] In actual use, first, after placing the U-shaped terminal body 6 on the lower mold shell 5, the other end of the U-shaped terminal body 6 is placed on the support plate 93. When the U-shaped terminal body 6 is placed above the support plate 93, the weight of the gravity block 94 can be increased. At this time, the slide plate 95 drives the support block 92 to move downward. By making the upper part of the support block 92 wider than the lower part, the support block 92 can push the pressure plate 96 to extend to both sides in the through hole on the fixing column 9 while the support block 92 moves downward, so that it is fixed to the upper part of the other side of the U-shaped terminal body 6, so that the U-shaped terminal body 6 can be fixed inside the lower mold shell 5, avoiding the movement of the U-shaped terminal body 6 when the wiring harness is placed inside the U-shaped terminal body 6 for tight pressing, making the contact between the wiring harness and the U-shaped terminal body 6 not stable enough, correspondingly increasing the stability of the U-shaped terminal body 6 and the wiring harness during the pressing process, preventing offset from causing poor riveting, and reducing the waste of production costs.

[0041] When the U-shaped terminal body 6 is fixed, the wiring harness can be placed in the U-shaped groove on the U-shaped terminal body 6. At this time, the device inside the push rod 12 of the device shell 11 is started, so that the push rod 12 can push the upper mold shell 7 to move downward. When the upper mold shell 7 moves downward, the limit plate 31 moves accordingly, and then through the movement of the limit plate 31, the outer walls on both sides of the limit plate 31 can contact the rotating rod 41 on the fixed shell 4 when the upper mold shell 7 moves downward. By limiting the movement direction of the rotating rod 41 and the limit plate 31, the stability of the upper mold shell 7 driven by the limit plate 31 can be increased. Qualitative, avoids the movement trajectory of the upper mold shell 7 being offset when the upper mold shell 7 presses the U-shaped terminal body 6 and the wiring harness downward, and accordingly limits the movement trajectory of the upper mold shell 7 to ensure that the U-shaped terminal body 6 and the wiring harness are riveted at a predetermined position, avoids offset or misalignment during the riveting process, and ensures the accuracy of the crimping position. The U-shaped terminal body 6 is tightly connected to the wiring harness through the riveting process to form a stable electrical connection point. This connection method can ensure the effective transmission of current and signals in the wiring harness, and prevents circuit breaks or poor contact caused by unreliable connections.

[0042] It should be noted that when the limiting plate 31 passes through the rotating rod 41 , the rotating rod 41 is driven to rotate, thereby reducing the friction between the limiting plate 31 and the rotating rod 41 .

[0043] When the interior of the upper mold shell 7 completely covers the lower mold shell 5 and continues to move downward, the upper mold shell 7 can generate a thrust on the buffer plate 8 while contacting the buffer plate 8, so that the buffer plate 8 squeezes the buffer elastic block 82 into the slot 81. At the same time, the upper mold shell 7 rivets the U-shaped terminal body 6, so that the U-shaped terminal body 6 and the wiring harness are tightly combined. The introduction of the buffer elastic block 82 effectively alleviates the direct impact of the upper mold shell 7 on the U-shaped terminal body 6 and the wiring harness. During the riveting process, the buffering effect can protect the U-shaped terminal body 6 and the wiring harness from damage, and it also helps to increase the service life of the mold.

[0044] Through the cooperation of the conductive rubber 51 arranged on the lower mold shell 5 with the metal sheet 52 and the grounding wire 53, the static electricity generated during the pressing of the U-shaped terminal body 6 and the wiring harness can be transferred to the metal sheet 52 through the conductive rubber 51, and finally discharged through the grounding wire 53. Due to the elasticity of the conductive rubber 51 itself, the conductive rubber 51 can always keep in contact with the U-shaped terminal body 6, avoiding the static electricity generated by the friction and contact between the materials during the pressing of the U-shaped terminal body 6 and the wiring harness. Accordingly, the static electricity generated during the pressing of the U-shaped terminal body 6 and the wiring harness can be discharged, preventing electric shock, sparks, etc. caused by static electricity accumulation, thereby improving personnel safety.

[0045] When the U-shaped terminal body 6 is pressed together with the wiring harness, the operator pulls the U-shaped terminal body 6 out from the inside of the pressure plate 96 and the support plate 93. The gravity of the support plate 93 is reduced, and the slide plate 95 can be pushed upward under the action of the reset spring 2 91. Then, through the movement of the slide plate 95, the support block 92 is pushed upward. At this time, the support of the support block 92 on the pressure plate 96 can be released. Under the action of the reset spring 3 97, the pressure plate 96 can be pulled into the interior of the fixed column 9. Since the support block 92 does not completely leave the pressure plate 96, the pressure plate 96 can be inside the through hole, avoiding the pressure plate 96 from being completely separated from the through hole, which correspondingly increases the working efficiency of the pressure plate 96 moving again.

[0046] When the upper mold shell 7 needs to be replaced after long-term use, first, the operator pushes the U-shaped rod 313 to the left, and then the U-shaped rod 313 slides inside the second slide groove 311, so that the U-shaped rod 313 can be released from the release of the limit rod 35. At this time, the fixation of the limit plate 31 by the second slide groove 311 can be released, and the U-shaped rod 313 is in contact with the limit rod 35, so that the stability of the limit plate 31 on the plug-in shell 3 can be increased, and the limit plate 31 is prevented from moving on the plug-in shell 3 when the limit plate 31 slides on the rotating rod 41, resulting in an unstable connection between the plug-in shell 3 and the connecting sleeve 71, and correspondingly increases the connection stability between the connecting sleeve 71 and the plug-in shell 3, thereby improving the working efficiency of the upper mold shell 7.

[0047] After releasing the fixation between the U-shaped rod 313 and the limit rod 35, the limit plate 31 can be pushed upward, and then through the movement of the limit plate 31, the connecting block 36 can drive the push block 34 to move upward. When the push block 34 squeezes the spring block 32 upward to leave one side of the limit rod 35, the limit rod 35 can be pushed into the interior of the plug-in shell 3 under the action of the reset elastic block 37, thereby releasing the fixation of the limit rod 35 and the connecting sleeve 71. At this time, the connecting sleeve 71 and the upper mold shell 7 can be removed from the plug-in shell 3 to complete the replacement of the upper mold shell 7. This operation is simple and quick, which is convenient for the operator to quickly replace the upper mold shell 7, thereby reducing the length of equipment downtime.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
