Abstract
Description
Technical Field
[0001] The invention belongs to the field of mechanical technology, and in particular relates to a large and small hole screening and material distribution system for a stepped hole type cylindrical part, and also relates to a method for using the system. Background Art
[0002] In the automated processing or assembly system of step hole parts, it is necessary to screen the large and small hole heads of the step hole parts. The existing technology is to screen through a screening system including vision or a mechanical screening system based on a vibration pot system. The screening system including vision or the mechanical screening system based on the vibration pot system adopts one-time screening. Due to the one-time screening, missed screening may occur. The missed screening often causes the missed workpiece to enter the subsequent process and cause material jamming and other faults, so that the subsequent process is interrupted. Summary of the invention
[0003] The purpose of the present invention is to overcome the above-mentioned disadvantages and provide a large and small hole screening and material separation system for stepped hole cylindrical parts and a method of using the system, which ensures the accuracy of the classification results by double screening and avoids missed screening.
[0004] The purpose of the present invention and the solution of its main technical problems are achieved by adopting the following technical solutions:
[0005] The invention discloses a large and small hole screening and material distribution system for a stepped hole type cylindrical part, comprising a track, a photoelectric sensor A, a cylinder, a push rod, a profiling groove, a photoelectric sensor B, a vibration pot, and an air pipe, wherein two ends of the track are respectively connected to a mounting seat and a vibration pot, a cylinder is installed at the lower end of the mounting seat, a lower end of the push rod is inserted into the cylinder, and an upper end is inserted into the mounting seat, a profiling groove is provided on the push rod, and the profiling groove is fixedly installed on the mounting seat, a hole is provided at one end of the track, and a hole cover is provided on the profiling groove, a photoelectric sensor A and a photoelectric sensor B are respectively installed on the side of the track, and an air pipe is installed on the vibration pot.
[0006] The vibration pot comprises a pot body, an outer shell, a vibration pump, a base and a spring. The vibration pump and the spring are respectively connected to the bottom of the pot body, and the vibration pump and the spring are installed on the base. The outer shell is covered outside the vibration pump, the base and the spring. The pot body is connected to the other end of the spiral track.
[0007] The contoured slot is tubular.
[0008] The push rod can move up and down in the mounting seat and the contoured groove.
[0009] The mounting seat is mounted on the bottom plate via a cylinder.
[0010] A method for using a large and small hole screening and material distribution system for a stepped hole type cylindrical part, comprising the following steps;
[0011] 1) The workpiece is converted from lying flat to standing upright;
[0012] Put the workpiece into the pot, start the vibration pump, the pot vibrates, and the workpiece is transformed from lying flat to standing upright;
[0013] 2) Air blowing material selection;
[0014] During vibration transmission, the upright workpiece is transmitted in a spiral shape along the track. When it is transmitted to the air pipe, the air blown out of the air pipe is aimed at the hole set on the workpiece, and the air is blown into the inner wall of the hole set on the workpiece, blowing the workpiece with a large hole diameter off the track, leaving the upright workpiece with a small hole diameter head upward to continue to be transmitted on the guide rail;
[0015] 3) Ejection and material selection;
[0016] When the workpiece is normally transferred to the profiling groove and falls into the profiling groove, the photoelectric sensor A and the photoelectric sensor B detect that the workpiece is in place. At this time, the control system triggers the cylinder, and the cylinder pushes the push rod, which is inserted into the large aperture of the workpiece under the large aperture, and the workpiece is ejected to a certain height. The workpiece is partially exposed to the profiling groove, and the workpiece exposed to the profiling groove is taken away. However, the workpiece under the small aperture cannot be inserted into the small aperture of the workpiece due to the push rod. The push rod contacts the lower end of the workpiece, and the workpiece under the small aperture is completely ejected from the profiling groove and falls, realizing secondary screening of ejection material selection.
[0017] Compared with the prior art, the present invention has obvious beneficial effects. It can be seen from the above technical scheme that the screening of the large and small heads of the step hole cylindrical standard parts is realized by screening the materials once by the guide rail and air blowing, and the secondary screening and material separation by the push rod. The workpiece posture is converted from lying to upright by the vibration pot with a specific track structure. During the vibration transmission process, the air blowing pipe installed on the side of the guide rail is used to adjust the air flow size through the throttle valve to blow off the large-aperture parts with large resistance, leaving the upright parts with small-aperture heads with small resistance upward to continue to be transmitted on the guide rail. When the parts are normally transmitted to the front-end profiling groove, the external sensor detects that the parts are in place. At this time, the control system triggers the ejection cylinder to eject the workpiece to a certain height, partially exposing the profiling hole. The profiling groove depth is consistent with the length of the workpiece, and the profiling groove and the outer diameter of the workpiece maintain a small tolerance. The material separation of the parts is realized. The workpiece with a small aperture is completely ejected from the profiling groove and then falls, and is screened twice, so that the accuracy of the classification results is guaranteed by two screenings, and no missed screening occurs.

[0031] The vibration pot 9 includes a pot body 11, an outer shell 12, a vibration pump 13, a base 14, and a spring 15. The vibration pump 13 and the spring 15 are respectively connected to the bottom of the pot body 11. The vibration pump 13 and the spring 15 are installed on the base 14. The outer shell 12 is covered on the outside of the vibration pump 13, the base 14, and the spring 15. The pot body 11 is connected to the other end of the spiral track 1.
[0032] The profiled groove 7 is tubular.

[0035] A method for using a large and small hole screening and material distribution system for a stepped hole type cylindrical part, comprising the following steps;
[0036] 1) The workpiece is converted from lying flat to standing upright;
[0037] The workpiece 16 is placed in the pot body 11, and the vibration pump 13 is started, so that the pot body 11 vibrates and the workpiece 16 is transformed from lying flat to standing upright;
[0038] 2) Air blowing material selection;
[0039] During vibration transmission, the upright workpiece 16 is spirally transmitted along the track 1, and the high-pressure gas is connected to the air pipe 10. The air pressure is adjusted. When the air is transmitted to the air pipe 10, the air blown out of the air pipe 10 is aimed at the hole set on the workpiece 16, and the air is blown into the inner wall of the hole set on the workpiece 16, so that the workpiece 16 with a large aperture is blown off the track 1, leaving the upright workpiece 16 with a small aperture head upward to continue to be transmitted on the guide rail;

At this time, the control system triggers the cylinder 4, and the cylinder 4 pushes the push rod 6. The push rod 6 is inserted into the large aperture of the workpiece 16 under the large aperture, and the workpiece 16 is pushed out to a certain height. The workpiece 16 is partially exposed to the profiling groove 7, and the workpiece 16 exposed to the profiling groove 7 is taken away. However, the workpiece 16 under the small aperture cannot be inserted into the small aperture of the workpiece 16 because the push rod 6 cannot be inserted into the small aperture of the workpiece 16. The push rod 6 contacts the lower end of the workpiece 16, and the workpiece 16 under the small aperture is completely pushed out of the profiling groove 7 and falls, realizing the secondary screening of ejection material selection.
