[0028] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0029] Please refer to Figures 1-7 In the embodiments of the utility model, a high-precision end face positioning mechanism for wire harness processing includes support frame 1, the support frame 1 top fixed installation has first sliding rail 11, and the first sliding rail 11 is installed with operating table 2 in coordination on it;Operating table 2 one side is fixedly connected with cylinder 3, and the output shaft one side of cylinder 3 is equipped with positioning mechanism 4, and positioning mechanism 4 one side is equipped with two first mechanical clamp jaws 5, and first mechanical clamp jaw 5 is fixedly connected with operating table 2, and the first mechanical clamp jaw 5 one side is equipped with two second mechanical clamp jaws 6, and is fixedly connected with operating table 2;Second mechanical clamp jaw 6 one side is equipped with wire harness support frame 7, and wire harness support frame 7 one side vertical board is fixedly connected with opposite light emitting photoelectric 71.
[0030] The power source provided by the cylinder 3 drives the positioning mechanism 4 to accurately adjust the position, thereby accurately positioning the end face of the wire harness, and the first mechanical clamp jaw 5 and the second mechanical clamp jaw 6 jointly act on the wire harness to improve the stability and reliability of clamping, prevent the wire harness from moving or deforming during processing, and ensure the processing accuracy; the wire harness support 7 provides support for the wire harness to keep the wire harness in a stable position during processing, and the light emitting diode 71 can detect the position and state of the wire harness, and timely send a signal when the position of the wire harness changes or an abnormal situation occurs, so that the operator can adjust or take corresponding measures.
[0031] In the embodiment, the positioning mechanism 4 is provided with a second sliding rail 22 at the bottom, and the second sliding rail 22 is fixedly connected with the operation table 2; the second sliding rail 22 is provided with a second sliding block 43 in cooperation, and the second sliding block 43 is fixedly connected with the bottom plate of the positioning mechanism 4.
[0032] Through the cooperation of the second sliding rail 22 and the second sliding block 43, the positioning mechanism 4 can move back and forth on the operation table 2, and the positioning mechanism 4 can be ensured to accurately contact the end face of the wire harness, thereby achieving high-precision positioning.
[0033] In the embodiment, two copper blocks 42 are provided above the bottom plate of the positioning mechanism 4, and the copper blocks 42 are fixedly connected with their fixed seats. The fixed seat of one of the copper blocks 42 is provided with a linear bearing in cooperation, and a guide rod is arranged inside the linear bearing and is in sliding connection with the linear bearing. The guide rod is fixedly connected with the fixed seat of the copper block 42 and the wire harness contact plate 44 at both ends. The wire harness contact plate 44 is fixedly connected with a spring 41 at the middle position of the guide rod, and the other end of the spring 41 is fixedly connected with a vertical plate of the linear bearing provided on the positioning mechanism 4.
[0034] During the processing of the wire harness, the wire harness contacts the wire harness contact plate 44, which drives the wire harness contact plate 44 to move backward, and simultaneously drives the two copper blocks 42 to contact and close. The copper blocks 42 generate a control signal when they close, and the control signal controls the electromagnetic valve on the cylinder of the first mechanical clamp jaw 5 and the second mechanical clamp jaw 6. When the electromagnetic valve is opened, the cylinder of the first mechanical clamp jaw 5 and the second mechanical clamp jaw 6 is closed, thereby driving the first mechanical clamp jaw 5 and the second mechanical clamp jaw 6 to clamp and fix the wire harness. The guide rod and the linear bearing have high cooperation precision to ensure that the guide rod does not jam or shake during sliding. The spring 41 provides a certain elastic force for the wire harness contact plate 44, which has a buffering effect and reduces the impact force on the wire harness.
[0035] In the embodiment, the bottom plate of the positioning mechanism 4 is provided with a groove at one end of the air cylinder 3, and a floating joint 31 is arranged in the groove.

The air cylinder 3 and the positioning mechanism 4 are connected, and the power of the air cylinder 3 is transmitted to the positioning mechanism 4. Since the floating joint 3 can slide within a certain range of the groove, the installation error and angle deviation between the output shaft of the air cylinder 3 and the positioning mechanism 4 can be compensated. The pushing force of the air cylinder 3 can be more smoothly transmitted to the positioning mechanism 4, and the uneven stress and jam caused by inaccurate installation can be avoided. In the working process, the action of the air cylinder 3 can generate vibration and impact. The existence of the floating joint 3 can absorb part of the vibration and impact energy, and reduce the influence on the positioning mechanism 4. The stop bolt 32 and the buffer 21 can prevent the positioning mechanism 4 from moving excessively under the pushing of the air cylinder 3, avoid collision with other components or exceed the designed working range, and provide a certain buffer force when the positioning mechanism 4 moves to the limit position, thereby reducing the impact force between the positioning mechanism 4 and the operation table or other components.

The cam follower 231 penetrates through the operation table 2 and is rotationally connected with the operation table 2.
[0038] By adopting the above technical scheme, the rodless cylinder 12 can greatly save the installation space and has high moving precision. The rodless cylinder 12 has strong load capacity and can provide stable support for the operation table 2 and other structures, thereby ensuring the reliability of the equipment in the working process. The first sliding block 23 is matched and installed with the guide rail 121, thereby ensuring that the first sliding block 23 can move stably along the predetermined track under the driving of the rodless cylinder 12. The cam follower 231 can make the first sliding block 23 run more stably, reduce vibration, and greatly reduce friction and wear, which is helpful to prolong the service life of the equipment.
