[0020] Embodiment 1

[0021] In Figures 1 to 5 In the schematic diagram of the present utility model shown, an automatic tubular part feeding device includes a cantilever, a cantilever connection block, a switching cylinder, a conveying mechanism, a feeding mechanism, a base, a cantilever, a cantilever frame, a movable compression mechanism, a stopper, a cantilever top post, and a clamping mechanism.

[0022] The cantilever 1 is fixed on the switching cylinder 13 through the cantilever connection block 12. The switching cylinder 13, the conveying mechanism, and the feeding mechanism 15 are fixed on the base 18. The feeding mechanism is a vibrating disk 15. The lower part of the inverted L-shaped cantilever 1 is fixed with a channel steel cantilever frame 3 with a lower opening. Two groups of movable compression mechanisms are arranged between the cantilever frames. The movable compression mechanism includes a stopper support rod 6 and a return spring 5. The two ends of the stopper support rod 6 are respectively connected to the two side walls of the cantilever frame 3. The return spring 5 and the stopper 4 are sleeved on the stopper support rod 6. The stopper 4 is composed of an upper connecting part and a lower blocking part connected. The width of the connecting part is smaller than the width of the blocking part. One side of the stopper 4 is in contact with the return spring. The cantilever inner side is fixed with a cantilever top post 2, and the cantilever top post is placed below the cantilever frame 3. The lower part of the stopper 4 is placed between the discharge port 17 of the feeding chute of the feeding mechanism 15 and the cantilever top post 2, and the two sides of the lower part of the stopper are respectively in contact with the feeding chute of the feeding mechanism and the cantilever top post. The clamping mechanism includes a material receiving table connecting plate 14, a downward pressing cylinder 10, a pressing block 9, and a material receiving table 11. The conveying mechanism includes a drag chain 19 and a longitudinal electric cylinder module 20. One end of the lower part of the drag chain is fixed on the base 18, and the other end is connected to the material receiving table connecting plate on the upper part of the longitudinal electric cylinder module 20 and moves together with the material receiving table connecting plate. The sliding seat on the longitudinal electric cylinder module 20 can drive the material receiving table connecting plate 14 to move, and the material receiving table connecting plate 14 is driven to move through the sliding of the conveying mechanism. The downward pressing cylinder 10 and the material receiving table 11 are fixed on the material receiving table connecting plate 14. The output end of the downward pressing cylinder 10 is connected to the pressing block 9. A material receiving table slot hole 16 is opened in the upper part of the material receiving table. The downward pressing cylinder can drive the pressing block 9 to move up and down, and the pressing block moves downward and can press on the groove on the upper part of the material receiving table.

[0023] Preferably, the utility model further includes a stopper connecting member 7 sleeved on the stopper support rod. One end of each of the two return springs 5 is fixed on the stopper connecting member 7, and the stopper connecting member 7 is fixed on the side of the stopper 4. The two groups of stopper support rods 6 pass through the stopper 4 through two holes to ensure that the stopper 4 does not swing in a non-horizontal direction; the cantilever top column 2 and the vibrating plate discharge port 17 jointly limit the non-horizontal swing of the stopper 4.

[0024] The automatic tubular part feeding device can be equipped with multiple vibrating plates, and the discharge grooves of the vibrating plates are of different sizes for discharging different workpieces.

[0025] During the use of the utility model, in the non-picking state, the discharge port 17 of the feeding groove of the vibrating plate 15 abuts against the front surface of the stopper 4. The return spring 5 sleeved outside the stopper support rod 6 is in a normal state, and one side of the stopper 4 is in contact with the return spring 5 through the stopper connecting member 7. The lower part of the stopper 4 is placed between the discharge port 17 of the feeding groove of the feeding mechanism and the cantilever top column 2, and both sides of the lower part of the stopper 4 are respectively in contact with the feeding groove of the feeding mechanism and the cantilever top column, so as to limit the non-horizontal swing of the stopper 4.

[0026] When it is necessary to pick up the material, the vibrating plate 15 is started, and the workpiece 8 moves by relying on the vibration of the vibrating plate 15 and moves along the feeding groove of the vibrating plate to the discharge port. The discharge port is located on the other side of the stopper 4. At this time, the workpiece 8 is in a state of waiting to be picked up. The longitudinal electric cylinder module 20 drives the drag chain 19 and the material receiving table connecting plate 14 to move. During the process, the pressing block 9 and the material receiving table 11 touch the stopper 4 and compress the return spring until the stopper 4 moves out from between the discharge port 17 of the feeding groove of the feeding mechanism and the cantilever top column 2 and the material receiving table slot hole 16 coincides with the discharge port 17 of the feeding groove. At this time, the longitudinal electric cylinder module 20 stops moving. The pressing block 9 moves upward under the action of the downward pressing cylinder 10 and separates from the material receiving table 11. At this time, under the push of the rear workpiece 8, the front workpiece 8 enters the material receiving table slot hole 16, and the pressing block 9 moves downward under the action of the downward pressing cylinder 10. The pressing block 9 presses on the material receiving table slot hole, and the workpiece 8 is pressed in the material receiving table slot hole 16 through the pressing block 9 to complete the feeding.

[0027] In order to meet the discharge requirements of different workpieces, the utility model can be equipped with multiple vibrating plates, and the discharge grooves of the vibrating plates are of different sizes. The output end of the switching cylinder 13 drives the cantilever to move, and by adjusting the position of the stopper, the stopper can correspond to the discharge ports 17 of the feeding grooves of multiple vibrating plates 15.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
