Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile parts manufacturing, in particular to a longitudinal beam production conveying line. BACKGROUND
[0002] The longitudinal beam is the main load-bearing component of the vehicle frame, which is usually made of high-strength steel to ensure sufficient strength and rigidity, thereby increasing the stability and torsional resistance of the vehicle frame.
[0003] Both the double-layer finished longitudinal beams are produced by using the plug welding process. The metal surface of the longitudinal beam needs to be treated by shot blasting. After shot blasting, a large number of steel shots are easily left in the joint gap. During the hoisting and assembly processes, the steel shots left in the joint gap of the longitudinal beam will fall to the ground due to the vibration of the longitudinal beam. Since the steel shots exist on the ground, the ground is slippery. Moreover, the fallen steel shots are not easy to collect, which poses a serious safety hazard. In addition, the steel shots that have not been removed will be electroplated with the assembled vehicle frame, which will pollute the tank liquid and cannot guarantee the appearance quality of the paint surface.
[0004] Currently, there are two common methods for processing the residual steel shots. One method is to use high-pressure air to blow out the steel shots in the joint gap of the longitudinal beam during the conveying process. This method has high energy consumption and is prone to dust and noise. The other method is to manually take a rubber hammer to hit the longitudinal beam during the conveying process. This method has low automation, high labor intensity, high labor cost, and the hitting force and frequency will decrease with the increase of working time in large-scale production, thereby reducing the working efficiency. TECHNICAL SOLUTION
[0005] To solve the technical problems of the existing longitudinal beam residual steel shot processing method, low automation, high cost, and poor processing effect in the background technology, the utility model provides a longitudinal beam production conveying line.
[0006] The technical scheme of the utility model is as follows:
[0007] The utility model provides a longitudinal beam production conveying line, which comprises a rack, two groups of conveying roller groups are arranged on the rack along the conveying direction at intervals, a vibration mechanism is arranged between the two groups of conveying roller groups, the top of the vibration mechanism is flush with the top of the conveying roller group, the vibration mechanism comprises a vibration bottom plate, a vibrator is arranged at the bottom of the vibration bottom plate, a photoelectric sensor and a control system are arranged on one side of the rack, the vibrator and the photoelectric sensor are connected with the control system, the longitudinal beam can be vibrated during the conveying process by using the vibration mechanism, which helps to shake off the steel shots and other impurities left in the joint gap of the longitudinal beam, thereby improving the cleanliness of the longitudinal beam, ensuring the quality of subsequent processing, and realizing the automatic control of the vibration process by the cooperation of the vibration mechanism, the photoelectric sensor, and the control system, improving the production efficiency and the accuracy of control, avoiding the long-term invalid work of the vibration mechanism, and effectively reducing the energy consumption.
[0008] Preferably, the two ends of the vibration bottom plate are fixedly connected with the rack through springs, which can play a buffering role, on the one hand, reducing the impact of the vibrator on the rack during operation, protecting the rack structure and prolonging its service life; on the other hand, the elastic effect of the spring can make the vibration more stable and uniform, which helps to better shake off the impurities on the stringers and also reduces the surface damage of the stringers caused by uneven vibration.
[0009] Preferably, the two ends of the vibration bottom plate are respectively connected with at least one spring, and multiple springs can more evenly distribute the stress, so that the vibration bottom plate can maintain better balance and stability during vibration, thereby improving the reliability and working performance of the vibration mechanism, more effectively removing the residual impurities on the stringers, and ensuring the production quality.
[0010] Preferably, the vibration bottom plate is in an inverted U-shaped structure, which can increase the structural strength of the vibration bottom plate and make it less likely to deform under greater vibration stress, at the same time, the U-shaped structure can better adapt to the shape of the stringer and provide more stable support for the stringer, so that the vibration energy can be more comprehensively transmitted during the vibration process, ensuring that all parts of the stringer can be effectively vibrated, and improving the impurity cleaning effect.
[0011] Preferably, the upper surface of the vibration bottom plate is flush with the top of the conveying roller group, which ensures the smoothness of the stringer when it transitions from the conveying roller group to the vibration mechanism, and prevents jamming or collision due to height difference, making the conveying process of the stringer more smooth and reducing damage such as scratches on the surface of the stringer, which is conducive to ensuring the appearance quality of the stringer and improving the continuity and stability of production.
[0012] Preferably, the photoelectric sensor is higher than the upper surface of the vibration bottom plate, which can accurately detect the position and running state of the stringer on the conveying line and avoid affecting the detection accuracy due to interference with the vibration bottom plate. Through accurate detection, the control system can start and stop the vibrator in a timely and accurate manner, realize precise control of the vibration process, improve the effect of vibrating and cleaning impurities, and also avoid unnecessary energy consumption and equipment wear and tear.
[0013] Preferably, the control system includes a controller, the photoelectric sensor is connected with the controller, and the controller is connected with the vibrator through a frequency converter.

[0014] Preferably, the vibrator is fixedly installed at the bottom center of the vibration base plate, which can make the vibration more evenly distributed on the vibration base plate and then transmitted to the longitudinal beam, so as to ensure that each part of the longitudinal beam is subjected to relatively balanced force during vibration, avoid that part of impurities cannot be effectively shaken off due to uneven vibration, improve the comprehensiveness and thoroughness of impurity cleaning, and also help to prolong the service life of the vibration mechanism and reduce local wear and damage caused by uneven vibration.
[0015] Preferably, a material receiving bin with an upper opening is arranged directly below the vibration mechanism and the conveying roller set, which can conveniently collect the steel shots and other impurities shaken off from the longitudinal beam, avoid the impurities from scattering on the ground, facilitate cleaning and recycling, prevent the impurities from falling around the equipment, reduce the pollution to the production environment, reduce the safety hazards such as slipping caused by impurity scattering, ensure the cleanliness and safety of the production site, and improve the convenience and standardization of production management.
[0016] Preferably, the conveying roller set comprises a plurality of conveying rollers arranged at intervals, and the conveying rollers are motor-driven structures, which can flexibly adapt to longitudinal beams of different sizes, improve the versatility of the conveying line, provide stable and reliable power through the motor-driven structure, ensure that the longitudinal beam moves smoothly and uniformly on the conveying line, and facilitate the coordinated work with other components such as the vibration mechanism, thereby improving the working efficiency and automation degree of the entire production conveying line and ensuring the continuity and stability of the longitudinal beam production process.
[0017] Through the above technical solutions, the advantages of the present application are as follows:
[0018] 1. The vibration mechanism is arranged between the two conveying roller sets, which can be used for vibration operation on the longitudinal beam during conveying, helps to shake off the steel shots and other impurities remaining in the longitudinal beam gap, thereby improving the cleanliness of the longitudinal beam and ensuring the subsequent processing quality.
[0019] 2. The upper surface of the vibration base plate is flush with the top of the conveying roller set, which ensures the stability of the longitudinal beam when it is transferred from the conveying roller set to the vibration mechanism, avoids jamming or collision due to height difference, makes the conveying process of the longitudinal beam more smooth, reduces damage such as scratching on the surface of the longitudinal beam, is conducive to ensuring the appearance quality of the longitudinal beam, and also improves the continuity and stability of production.
[0020] 3. The photoelectric sensor is higher than the upper surface of the vibrating base plate, which can accurately detect the position and running status of the longitudinal beam on the conveyor line. This avoids interference with the vibrating base plate, which would affect the detection accuracy.
