Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to an improved conveying line. Background Art

[0002] A stepper conveyor is a conveying machine that can intermittently convey workpieces and can keep several identical workpieces being conveyed at equal intervals. The existing crankshaft processing line intermittently circulates crankshafts through a stepper conveyor 7 in conjunction with a lifting mechanism. The stepper conveyor 7 is provided with a plurality of crankshaft feeding fixtures for conveying crankshafts. The stepper conveyor 7 drives the crankshaft feeding fixtures to intermittently advance and retreat, and the lifting mechanism drives the stepper conveyor 7 to intermittently lift and lower. The lifting mechanism generally uses a cylinder 70 as a power source. Since the stepper conveyor 7 is too long and too heavy, multiple cylinders are required to achieve horizontal lifting, and it is difficult for multiple cylinders to achieve synchronous lifting. Different cylinders have different lifting speeds, and the stepper conveyor 7 cannot achieve horizontal lifting. Therefore, the stepper conveyor 7 needs to be configured with the same The stepping mechanism, the stepping conveyor 7 is provided with a lifting rack 72 along the height direction on the side wall of multiple guide shafts 71. The lifting rack 72 is meshed with the lifting gear 73. The multiple lifting gears are synchronously driven by the transmission shaft 74. When the cylinder drives the stepping conveyor 7 to rise and fall, the multiple guide shafts 71 and their lifting racks 72 rise and fall along with the stepping conveyor 7. The lifting rack 72 rises and falls, driving the lifting gear 73 to rotate. Even if the air pressure of one of the cylinders is low and the speed is slow, the synchronous structure can ensure that all positions of the stepping conveyor 7 rise and fall synchronously, thereby realizing the synchronous driving of the stepping conveyor 7 by multiple cylinders. However, the existing synchronous mechanism has the following problems: (1) After long-term use, the lifting rack 72 and the lifting gear 73 are seriously worn, and the lifting rack 72 and the lifting gear 73 are easily dislocated. The lifting rack 72 and the lifting gear 73 cannot be synchronized, or the synchronization effect is deteriorated, and the use is unstable. (2) If the stepping conveyor 7 or the crankshaft processing line tilts to one side, the lifting rack and the lifting gear will easily become dislocated, and the lifting rack and the lifting gear will lose synchronization or have poor synchronization. Therefore, the existing conveyor structure needs to be further improved. Utility Model Content
