Description

Technical Field

[0001] The utility model relates to the technical field of thread rolling machines, in particular to a feeding mechanism of a thread rolling machine for screws. Background Art

[0002] The thread rolling machine is a machine specialized in producing screws. The flat thread rolling machine is the most common thread rolling machine. The main working principle of the flat thread rolling machine is: two thread rolling blocks with the same thread as the bolt, the bolt blank is in between the two thread rolling blocks, and by fixing one thread rolling block, the machine drives the other thread rolling block to form relative motion with the fixed thread rolling block, thereby rolling out threads on the bolt blank between the two thread rolling blocks.

[0003] Traditional flat-plate thread rolling machines rely on manual feeding to place bolt blanks one by one at the designated processing position, which makes thread rolling machine loading inconvenient, low in productivity, and increases workers' workload. Therefore, we propose a screw thread rolling machine feeding mechanism to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a feeding mechanism for a screw thread rolling machine, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions:

[0006] The utility model is a feeding mechanism for a screw thread rolling machine, comprising a mounting base, a support frame 1 being fixedly mounted on the upper surface of the mounting base, a support frame 2 being provided on one side of the support frame 1, and the support frame 2 being fixedly mounted on the upper surface of the mounting base, a roller for feeding the thread rolling machine being rotatably connected to one side of the support frame 1, a screw rail for loading the thread rolling machine being fixedly mounted inside the support frame 2, and one end of the screw rail being inserted into the roller.

[0007] Furthermore, the roller includes a feeding barrel, an annular baffle, a rotating frame and a partition. The feeding barrel is arranged on one side of the support frame. Annular baffles are fixedly arranged on both sides of the feeding barrel. A rotating frame is fixedly installed on the side of one of the annular baffles away from the feeding barrel, and the rotating frame is rotatably connected to one side of the support frame. The partition is arranged around the inner side of the feeding barrel, and the partition is fixed to the feeding barrel.

[0008] Furthermore, the screw rail includes a track, an upper limit conveying groove and a lower limit conveying groove. The track is fixedly installed on the upper part of the support frame 2. The upper limit conveying groove is opened on the upper surface of the track, and the lower limit conveying groove is opened on the lower surface of the track.

[0009] Furthermore, the upper limit conveying trough is communicated with the lower limit conveying trough, and the width of the upper limit conveying trough is greater than the width of the lower limit conveying trough.

[0010] Furthermore, a support frame three is provided below the feeding barrel, and the support frame three is fixedly mounted on the upper surface of the mounting base plate. Support rollers are rotatably connected inside the support frame three, and the support rollers are symmetrically arranged inside the support frame three.

[0011] Furthermore, a motor is fixedly mounted on a side of the support frame away from the rotating frame, and the rotating frame is fixedly mounted on an output end of the motor, and a vibrator is fixedly mounted on one side of the track.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model provides a roller, and inserts the screw rail into the roller. When the feeding roller rolls, the screw blanks on the partition fixed on the inner side of the feeding roller fall onto the track. Utilizing the structural characteristics of the screw blanks themselves, the nail bodies fall into the lower limit conveying groove opened on the track, and the nail heads fall into the upper limit conveying groove opened on the track. The screw blanks will be transported along the track to the thread rolling machine, realizing automatic loading, making the thread rolling machine loading automated, convenient and efficient, which is beneficial to improving the thread rolling efficiency of the thread rolling machine and reducing the workload of workers.

When the thread rolling machine feeding mechanism is used, the mounting base 1 of the mechanism is fixedly mounted on the thread rolling machine, and a number of screw blanks, that is, unrolled screws, are poured from the holes in the middle of the annular baffle 5 into the drum composed of the feeding drum 4, the annular baffle 5, the rotating frame 6 and the partition 7. The side of the support frame 2 away from the drum is fixedly mounted with a motor 3, and is rotatably connected to the support frame The rotating frame 6 on one side of the support frame 2 is fixedly installed on the output end of the motor 3. When the motor 3 is started, the motor 3 drives the drum to rotate through the rotating frame 6 fixedly set at its output end. When the drum rotates, the screw blanks placed inside the drum are flipped by the partition 7 fixedly set on the inner side of the feeding barrel 4, so that the screw blanks on the upper inner side of the drum slide along the surface of the partition 7. The screw blanks sliding down from the surface of the partition 7 pass through the middle of the feeding barrel 4 and fall again between several partitions 7 fixedly set on the inner side of the feeding barrel 4. A support frame three 13 is provided under the feeding barrel 4, and the support frame three 13 fixedly mounted on the upper surface of the mounting base 1 is rotatably connected to the internal support roller 14. The support roller 14 is symmetrically arranged inside the support frame three 13, and the outer surface of the support roller 14 is connected to the outer surface of the feeding barrel 4. When the drum rotates slowly, the support roller 14 rolls relatively along the outer side of the feeding barrel 4, and the support roller 14 plays a supporting role for the drum.

[0021] A support frame 2 8 is provided on one side of the support frame 1 2, and the support frame 2 8 is fixedly mounted on the upper surface of the mounting base 1, a track 9 is fixedly mounted on the upper part of the support frame 2 8, and one end of the track 9 is inserted into the interior of the drum from the hole in the middle of the annular baffle 5, an upper limit conveying groove 10 is provided on the upper surface of the track 9, and a lower limit conveying groove 11 is provided on the surface of the track 9, and the lower limit conveying groove 11 is connected to the upper limit conveying groove 10. It is worth noting that the width of the lower limit conveying groove 11 is smaller than the width of the upper limit conveying groove 10, and the width of the upper limit conveying groove 10 should be larger than the diameter of the nail head of the screw blank, and the width of the lower limit conveying groove 11 should be larger than the diameter of the nail body of the screw blank. The screw rail composed of the track 9, the upper limit conveying groove 10 and the lower limit conveying groove 11 is tilted at a preset angle, and the higher end is inserted into the interior of the drum through the hole in the middle of the annular baffle 5. When the drum rotates slowly, the screw blank slides along the partition 7 fixed on the inner wall of the feeding drum 4, and the screw blank falls on the screw rail. Among the screw blanks falling on the screw rail, the screw blank whose nail body passes through the lower limit conveying groove 11 opened on the lower surface of the track 9 will remain on the screw rail, while the screw blank whose nail body does not pass through the lower limit conveying groove 11 will fall back between the several partitions 7 fixed on the inner side of the feeding drum 4. A vibrator 12 is fixedly installed on one side of the track 9. Under the vibration of the vibrator 12, the screw blank remaining on the screw rail will move along the track of the track 9, and then the screw blank will be neatly transported to the thread rolling machine, so that the thread rolling machine can perform screw threading.
