The working mechanism is as follows:
the slide block 4 is finally driven to slide along the slide rail 3 through the driving of the air cylinder 5 and the transmission of the connecting rod 6, the through hole 8 on the slide block 4 repeatedly moves in and out of the charging bucket 2 from the bottom, when the charging bucket moves in, a workpiece steel ball in the charging bucket falls into the through hole 8, after the charging bucket moves out, the slide block 4 continues to move, the through hole 8 with the workpiece steel ball is coupled with the through hole 8 on the slide rail 3, and the workpiece steel ball falls down to finish the feeding.
In the process, when a plurality of workpiece steel balls are arranged in the charging bucket 2, one workpiece steel ball can be completely embedded into the through hole 8, but the bottom surface of each workpiece steel ball is embedded into the through hole 8, when the through hole 8 is moved out of the wall of the charging bucket 2 along the front-back direction, the workpiece steel balls completely embedded into the through hole 8 can smoothly pass through the lower part of the through hole, but the steel balls with the lower parts submerged into the through hole 8 can be shielded, and the cut angles 12 can enable the workpiece steel balls to be more smoothly moved out of the through hole.
When the sliding block 4 continues to move along the sliding block 3, the cut single-lattice workpiece steel balls fall into the sliding groove 13, and when the single-lattice workpiece steel balls are started to the through hole 8 on the sliding rail 3, the cut angle 12 on the sliding rail 3 can ensure that the single-lattice workpiece steel balls can fall more smoothly.
The blanking step can be regarded as the free falling body of the workpiece steel ball, but if the moving speed of the slide block 4 is too high, the two through holes 8 are decoupled when the workpiece steel ball is not wound with enough speed, the steel ball can not fall, and the condition of empty material is caused,
however, if the moving speed of the slide block 4 is too slow, the feeding speed is too slow, and the production efficiency is affected.
In order to compromise production efficiency and blanking accuracy, this design adopts partial buffering design, guarantees efficiency promptly at blank in-process, then progressively slows down at the blanking step, guarantees the material loading of success, and its concrete principle is:
during the cutting process, no matter the cylinder shaft of the air cylinder 5 extends or resets, namely, no matter the through hole 8 moves into the material barrel 2 or moves out of the material barrel 2, the pressing block 14 is not contacted with the shaft cap of the sliding shaft 15, namely, the spring 16 does not work, the speed of the pressing block is based on the cylinder shaft speed of the air cylinder 5, the efficiency is ensured,
when the through hole 8 of the sliding block 4 is close to the through hole 8 of the sliding rail 3, the pressing block 14 is contacted with the shaft cap, the sliding shaft 15 is pressed into the sliding rail 3, meanwhile, the spring 16 can be gradually compressed, the reset elastic force of the spring hinders the cylinder 5 from driving the sliding block 4, the speed reduction is realized, the resistance is maximum when the two through holes 8 are coupled, the coupling time is increased, the longer falling time of the workpiece steel ball is given, the successful falling is ensured,
in the next feeding cycle, the spring 16 will firstly realize the reset, and the elastic force direction of the last process is the same as the driving direction of the cylinder shaft of the air cylinder 5, thereby providing the efficiency of the material cutting in the next feeding cycle.
Meanwhile, a baffle can be arranged at the head end of the sliding rail 3 to limit the coupling.
Compared with the blanking step, the blanking step does not need to worry about the problem that the steel balls of the workpiece fall into the through holes 8, firstly, more steel balls are arranged in the charging bucket 2, secondly, the through holes 8 continuously move in the charging bucket 2, and the steel balls falling into the through holes in the moving process have moving space and possibility, so that the efficiency can be improved.
The selection of the inner diameter of the through hole 8 on the sliding block 4 depends on the diameter of the workpiece steel ball and the efficiency and the precision degree determined by the inner diameter, when the inner diameter is closer to one time of the diameter of the workpiece steel ball, the fault tolerance rate of blanking and blanking is reduced, the efficiency is influenced, but after the workpiece steel ball enters the through hole 8, the possibility that other steel balls enter the through hole 8 is lower, and the through hole 8 on the sliding block 4 can move out of the charging basket 2 more smoothly,
on the contrary, when the inner diameter of the through hole is closer to twice the diameter of the steel ball, the fault tolerance rate is higher, the workpiece is easier to fall into the through hole 8, the feeding efficiency can be improved, but more space is provided for the redundant steel ball to be embedded into the through hole 8, the embedded part is deeper, during discharging, larger stress is generated with the inner wall of the charging basket 2, discharging is not smooth, and even the damage to the steel ball or the inner wall of the charging basket 2 is caused, so the specific inner diameter of the through hole 8 is determined according to the feeding requirement, the strength of the charging basket 2 and the material of the steel ball, and is preferably 1.1-1.6 times the diameter of the steel ball.
For the selection of the inner diameter of the through hole on the slide rail 3, when the inner diameter is closer to one time of the diameter of the workpiece steel ball, the advantages and disadvantages are the same as those of the through hole 8 on the slide block 4, and when the inner diameter is closer to two times of the diameter of the workpiece steel ball, the blanking precision, namely the deviation of the falling position of the workpiece steel ball, can be influenced, so that the selection of the inner diameter is preferably 1.3-1 times of the diameter of the workpiece steel ball depending on the requirement of the blanking precision.
The diameters of the through hole on the sliding rail 3 and the through hole on the sliding block 4 can be different.
Furthermore, can also be based on the above-mentioned mechanism of operation of the utility model, the attached functional subassembly of installation, if the installation sensor is in order to detect 2 interior work piece steel balls of storage bucket quantity, perhaps through clamp installation circuit breaker on cylinder 5 to install automatically controlled air throttle on 5 air cocks of cylinder, realize the automatically controlled etc. to the air supply.
Above-mentioned technical scheme has only embodied the utility model discloses technical scheme's preferred technical scheme, some changes that this technical field's technical personnel probably made to some parts wherein have all embodied the utility model discloses a principle belongs to within the protection scope of the utility model.
