Description

Technical Field

[0001] The utility model relates to the technical field of metal structural part processing, in particular to an automatic feeding device for metal structural parts. Background Art

[0002] The cylindrical metal structural part has a columnar structure, and a convex short column is provided at its end. This metal structural part is processed by a machining center. When processing, if the manual feeding method is adopted, the efficiency is low, and the working intensity of the operator is also large. Therefore, how to automatically feed such workpieces has become an urgent technical problem to be solved. When feeding the metal structural part, first, how to realize the automatic discharging of the structural part, and second, how to correct the posture of the structural part to meet the later processing requirements. Summary of the Utility Model

[0003] The utility model provides an automatic feeding device for metal structural parts to solve the deficiencies of the above-mentioned prior art, solve the problem of automatic feeding of structural parts, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technology is proposed:

[0005] An automatic feeding device for metal structural parts includes a flat plate. Multiple support rods are provided on the flat plate. Multiple vertical rods extend upward from the flat plate. An upper mounting plate is installed on the vertical rods. An upper ring is provided at the inner end of the upper mounting plate. A conical shell is provided at the lower end of the upper ring. A downward extension tube is provided at the lower end of the conical shell. A movable tube is inserted into the downward extension tube. A lower tube is sleeved at the lower end of the movable tube. A discharge port is opened at the lower end of the lower tube. A lower plate is provided at the lower end of the lower tube. A ring plate is provided on the outer periphery of the lower plate. A blanking port is opened at one end of the lower plate. A notch is opened on one side of the ring plate. A reciprocating mechanism is provided on the flat plate, and the reciprocating mechanism is used to drive the movable tube to reciprocate up and down. A first cylinder is provided at the lower end of the lower tube. A second cylinder is provided on the ring plate, and the movable end of the second cylinder faces the notch. When the reciprocatingly moving movable tube moves, it can make the structural part enter the movable tube, so that the structural part enters the downward extension tube, and finally the structural part is discharged outward through the discharge port. In this way, the discharging operation of the structural part is completed. At this time, the postures of the structural parts are uneven, and the short columns on them may face up or down. If they face down, due to their small contact area, they are likely to fall under the action of the first cylinder. When the short columns face up, they can be directly pushed to the blanking port by the first cylinder, and then directly discharged. The second cylinder can push the structural part in a lying posture to the notch, select it, and then adjust its posture.

[0006] Further, in order to facilitate the dumping of the structural part, the movable end of the first cylinder is located below the discharge port.

[0007] Further, in order to enable the structural member to automatically adjust its attitude, a concave shell is provided at the notch. A rectangular opening is formed at the bottom of the concave shell. A stop bar is provided at a position one-third of the length direction of the rectangular opening. When the end of the structural member without the short column moves to the rectangular opening, due to its gravity, the structural member will naturally fall under the action of the stop bar, with the short column facing upward, and finally complete the attitude adjustment of the structural member.

[0008] Further, in order to guide the movement of the movable pipe, guide strips are formed on the outer periphery of the movable pipe. Limiting grooves are formed on the inner walls of the lower pipe and the lower extension pipe. The guide strips are inserted into the limiting grooves, and the guide strips can rotate in the limiting grooves.

[0009] Further, in order to facilitate increasing the reciprocating movement frequency of the movable pipe, the so-called reciprocating mechanism includes a driving seat installed on the flat plate. A motor is installed on the driving seat. The output shaft of the motor is connected to a turntable. A long hole is formed in the turntable. A plug rod is provided on the movable pipe, and the plug rod passes through the long hole.

[0010] Further, in order to reduce the resistance when the movable pipe moves upward and also facilitate the structural member to enter the movable pipe, the upper end of the movable pipe is in a wedge-shaped structure.

[0011] The advantages of the above technical solutions are as follows:

[0012] The utility model is convenient for discharging and attitude adjustment of the structural member, thereby improving the processing efficiency of the structural member. BRIEF DESCRIPTION OF THE DRAWINGS

Multiple vertical rods 11 extend upward from the flat plate 1. An upper mounting plate 12 is installed on the vertical rods 11. An upper ring 2 is provided at the inner end of the upper mounting plate 12. A conical shell 20 is provided at the lower end of the upper ring 2. A downward extension pipe 21 is provided at the lower end of the conical shell 20. A movable pipe 22 passes through the downward extension pipe 21. The upper end of the movable pipe 22 is in a wedge shape. A lower pipe 25 is sleeved at the lower end of the movable pipe 22. A discharge port is opened at the lower end of the lower pipe 25. A lower plate is provided at the lower end of the lower pipe 25. A ring plate 27 is provided on the outer periphery of the lower plate. A blanking port is opened at one end of the lower plate. A notch 26 is opened on one side of the ring plate 27.

[0017] A reciprocating mechanism is provided on the flat plate 1. The reciprocating mechanism is used to drive the movable pipe 22 to reciprocate up and down. The reciprocating mechanism includes a driving seat 3 installed on the flat plate 1. A motor 30 is installed on the driving seat 3. The output shaft of the motor 30 is connected to a turntable 31. A long hole is opened on the turntable 31. A plug rod 24 is provided on the movable pipe 22. The plug rod 24 passes through the long hole. A guiding strip 23 is formed on the outer periphery of the movable pipe 22. Limiting grooves are opened on the inner walls of the lower pipe 25 and the downward extension pipe 21. The guiding strip 23 passes through the limiting grooves, and the guiding strip 23 can rotate in the limiting grooves.
