Description

Technical Field

[0001] The invention relates to the technical field of shaft processing, in particular to a metal shaft loading machine. Background Art

[0002] Gas springs are parts that can achieve functions such as support, buffering, braking, height and angle adjustment. In engineering machinery, they are mainly used in covers, doors and other parts. Gas springs are mainly composed of piston rods, pistons, sealing guide sleeves, fillers, pressure cylinders and joints. The pressure cylinder is a closed cavity filled with inert gas or oil-gas mixture. The pressure in the cavity is several times or dozens of times the atmospheric pressure. When the gas spring is in action, the pressure difference on both sides of the piston is used to realize the movement of the piston rod.

[0003] The piston rod is usually automatically processed by a piston rod CNC machining center. The metal shafts used in piston rod processing are usually automatically loaded by a robot and a push plate feeder. Usually, one robot assists two piston rod CNC machining centers to load the materials. However, friction and noise occur when the push plate of the push plate feeder reciprocates up and down, which will cause certain harm to the workers' hearing. At the same time, the loading process requires the processed piston rod to be removed first, and then a new metal shaft is clamped to the processing position. The processing interval between the two piston rods is long, and the overall processing efficiency is low. For this reason, we propose a metal shaft loader. Summary of the invention

[0035] The present invention provides a metal shaft loading machine, and its working principle is as follows:

[0036] Place the metal shaft feeding machine at a suitable position beside the piston rod processing center, and electrically connect each electrical appliance to the controller of the piston rod processing center. During operation, pour the raw material of the piston rod into the interior of the feeding bin 23, and the output shaft of the motor 25 rotates to drive the rotating shaft 1 and the synchronous pulley 21 on the front side to rotate. The synchronous belt 1 rotates, and the feed plate 24 transports the raw material of the piston rod to the front side of the feeding bin 23. The bottom wall of the feeding bin 23 tilts backwards, and the block 22 prevents the raw material of the piston rod from accumulating at the rear end of the bottom wall of the feeding bin 23. Similarly, the motor 26 drives the feed plate 2 27 rotates to convey the raw materials upward, and then the raw materials fall from the arc plate of the front side wall of the feeding bin 23 into the right end of the conveying frame 32. The conveying plate 27 is an arc-shaped conveying plate. The length of the conveying plate 27 is smaller than the diameter of the raw material of the piston rod, so that the conveying plate 27 can only convey one raw material at a time to avoid the accumulation of raw materials at the right end of the conveying frame 32. The output shaft of the motor 31 drives the conveying wheel 35 at the right end to rotate, and drives the conveyor belt to rotate. The raw materials are conveyed to the left at the upper end of the conveyor belt. The support plate 34 provides support for the middle part of the conveyor belt. The telescopic end of the cylinder 2 53 moves downward, and the fixed frame 52 The pneumatic clamp 54 descends, and the clamping part of the pneumatic clamp 54 falls to the inside of the vertically adjacent avoidance opening 33. Then the pneumatic clamp 54 clamps the raw material, and the telescopic end of the cylinder 2 53 is retracted. The slide of the linear guide 55 drives the cylinder 2 53 to move forward until the raw material moves to the processing position of the piston rod processing center. The clamping mechanism of the piston rod processing center is started to clamp the raw material for processing. After the processing is completed, the telescopic end of the cylinder 1 410 is pushed out, driving the fixed block 409 to move forward, the support shaft 408 slides out of the cylinder 401, and the slot plate 405 moves forward to the processing position. At the lower end of the position, the clamping mechanism of the piston rod processing center is released, and the processed piston rod falls into the interior of the slot plate 405, and then the telescopic end of the cylinder 410 is retracted, the slot plate 405 moves backward, the flip plate 404 touches the flip rod 406, the torsion spring 407 is twisted, the slot plate 405 flips backward, and the piston rod inside the slot plate 405 slides into the collection bin 402. When the telescopic end of the cylinder 410 is pushed out, the elastic potential energy of the torsion spring 407 drives the slot plate 405 to reset, and the limit rod 403 contacts the front side of the slot plate 405 to keep the slot plate 405 in a vertical state.
