Description

Technical Field

[0001] The utility model relates to a feeding device, in particular to an automatically oriented feeding device. Background Art

[0002] During the fine turning of gears, the direction of the special-shaped hole is required to be consistent with the direction of the hole slot of the driving center. When the robot is loading, if the orientation of the special-shaped hole of the workpiece is inconsistent with the hole slot of the driving center, the workpiece cannot be inserted into the center, thereby slowing down the loading efficiency. At the same time, when loading, the direction of the special-shaped hole of the workpiece is random. If the direction of the special-shaped hole is changed manually each time, it will cause manpower consumption. Therefore, if the orientation problem of the special-shaped hole of the workpiece is not solved, automated processing will not be achieved. Utility Model Content

[0021] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Component models, material names, connection structures, control methods, algorithms and other features not clearly described in this technical solution are all considered to be common technical features disclosed in the prior art.

[0022] Example

[0023] This embodiment provides an automatic directional loading device for adjusting the position of a workpiece 7 so that the position of the special-shaped hole of each workpiece is in the same position after adjustment by the device, wherein the workpiece 7 is rod-shaped and has a special-shaped hole at the tail end;

[0024] The device comprises: a bottom plate 9,

[0025] A workpiece placement plate 1 for placing the workpiece 7. In this embodiment, two workpiece placement plates 1 are provided, and a groove is formed on the workpiece placement plate 1. The workpiece 7 is placed in the groove, so that the workpiece 7 is placed more firmly;

[0026] A positioning piece for adjusting the position of the special-shaped hole of the workpiece 7, and a rotary cylinder 2 for driving the positioning piece:

[0027] In this embodiment, the positioning member includes:

[0028] The positioning block 3 is consistent with the shape of the special-shaped hole of the workpiece 7.

[0029] A sleeve 4 is sleeved outside the positioning block 3, wherein the positioning block 3 partially extends outside the sleeve 4, and the portion of the positioning block 3 located inside the sleeve 4 is also integrated with a displacement block 6, wherein a displacement hole 5 is opened on the side wall of the sleeve 4, and the displacement block 6 extends from the displacement hole 5 of the sleeve 4;

[0030] In this embodiment, the positioning block 3 is elastically connected to the rotary cylinder 2 through an elastic member and the positioning block 3 is movably arranged in the sleeve 4. The sleeve 4 is fixedly connected to the rotary cylinder 2 by a plurality of bolts.

[0031] In this embodiment, a slide cylinder 10 is further provided to drive the positioning member and the rotary cylinder 2 to move toward the position of the workpiece 7, and the positioning member and the rotary cylinder 2 are fixedly arranged on the slide cylinder 10;

[0032] In order to prevent the workpiece 7 from being ejected and falling when the slide cylinder 10 drives the positioning member and the rotary cylinder 2 to move toward the position of the workpiece 7, the device of this embodiment is further provided with a top plate 11, which is arranged in front of the workpiece placement plate 1;

[0033] In this embodiment, the workpiece placement plate 1, the slide cylinder 10, and the top plate 11 are all arranged on the bottom plate 9.

[0034] The device also includes a displacement sensor 8 for sensing the position of the positioning block 3. The rotary cylinder 2 drives the positioning block 3 to rotate until the positioning block 3 matches the special-shaped hole of the workpiece 7. The rotary cylinder 2 drives the positioning block 3 and the workpiece 7 to rotate again. When the positioning block 3 returns to the initial position, the displacement sensor 8 is electrically connected to the rotary cylinder 2 and transmits a signal to the rotary cylinder 2, and the rotary cylinder 2 stops rotating. The displacement sensor 8 is also arranged on the slide cylinder 10 and is consistent with the height of the displacement block 6.

[0035] When the automatic directional loading device provided in this embodiment is working: the manipulator grabs the workpiece 7 from the loading disk and places it on the workpiece placement plate 1 of the automatic directional loading device, and the slide cylinder 10 drives the rotary cylinder 2, the positioning piece, and the displacement sensor 8 to move forward together, and the positioning block 3 is pressed against the workpiece 7. At this time, the orientation of the positioning block 3 is set to the initial position, and the displacement block 6 which is integrated with the positioning block 3 and the displacement sensor 8 are provided opposite to the displacement block 6. Since the orientation of the special-shaped hole is not fixed each time the workpiece 7 is placed, the positioning block 3 cannot guarantee that it matches the special-shaped hole of the workpiece 7 every time. Since the positioning block 3 is connected to the rotary cylinder 2 by a spring and is movably arranged in the sleeve 4, when it does not match, the positioning block 3 will be pressed into the sleeve 4, and the spring will be compressed. At this time, the displacement block 6 will be displaced in the displacement hole 5, and the displacement sensor detects When the position change of the displacement block 6 is detected, a signal is transmitted to the rotary cylinder 2, and the rotary cylinder 2 starts to rotate, driving the positioning block 3, the displacement block 6, and the sleeve 4 to rotate together. When it rotates to match the special-shaped hole of the workpiece 7, the spring straightens. At this time, due to the change in orientation of the displacement block 6, the displacement sensor 8 still cannot sense the existence of the displacement block 6, and the rotary cylinder 2 will continue to rotate. At this time, since the positioning block 3 matches the workpiece 7, it will drive the workpiece 7 to rotate together. When returning to the initial position, the displacement sensor 8 senses that the displacement block 6 has returned to its position and transmits a signal to the rotary cylinder 2, and the rotary cylinder 2 stops rotating. Driven by the rotary cylinder 2, the workpiece 7 also rotates to the initial position together with the positioning block 3, that is, the position that meets the installation requirements. At this time, the manipulator clamps the workpiece 7 (without changing the orientation of the workpiece 7) and puts it into the next process.

[0036] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
