Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical tooling, in particular to an anti-misalignment positioning mechanism for pipe parts. Background Art
[0002] When operators place tube parts such as nuts, bushings and metal sleeves in tooling, they generally use human vision or sensors to prevent errors. For example, for nuts with large and small heads, if they are placed in the right position, the sensor will not report an error. If they are placed in the wrong position, the sensor will report an error, and then the operator will change the position of the nut. However, this method requires a large investment in sensor maintenance in the later stage. Alternatively, the operator first identifies the large and small heads of the nut by human vision and then places the nut. However, this operation method has high manpower and material costs. Summary of the invention
[0003] The technical problem to be solved by the utility model is to provide an anti-misalignment positioning mechanism for pipe parts, which can not only reduce the manpower and material costs but also is easy to operate.
[0004] The technical solution adopted by the utility model to solve the above-mentioned technical problems is: an anti-error positioning mechanism for pipe parts, comprising an adjustment mounting seat, an angle adjustment mechanism, a guide shaft and an anti-error base with a central through hole, the anti-error base is tilted on the adjustment mounting seat through the angle adjustment mechanism, the guide shaft extends downward into the central through hole, a locking mechanism for locking the position of the guide shaft is arranged between the guide shaft and the anti-error base, and an annular positioning groove is arranged on the upper part of the anti-error base surrounding the guide shaft.
[0005] The angle adjustment mechanism includes a first locking bolt and a second locking bolt. A rotation hole and an arc-shaped adjustment hole are provided on the adjustment mounting seat. The rotation hole is located obliquely above the arc-shaped adjustment hole. A first positioning hole corresponding to the rotation hole and a second positioning hole corresponding to the arc-shaped adjustment hole are provided on the anti-error base. The first locking bolt passes through the rotation hole from outside to inside and extends into the first positioning hole. The second locking bolt passes through the arc-shaped adjustment hole from outside to inside and extends into the second positioning hole. The rotation hole can be located obliquely above the front side of the arc-shaped adjustment hole, or the rotation hole can be located obliquely above the rear side of the arc-shaped adjustment hole. The angle of the anti-error base on the adjustment mounting seat can be adjusted through the arc-shaped adjustment hole, and it can be applicable to different types of pipe parts.
[0006] The locking mechanism includes a positioning screw and a positioning screw hole provided on the anti-mistake base, wherein the positioning screw is screwed inwardly into the positioning screw hole and is pressed against the guide shaft. The positioning screw can lock the guide shaft moved to a suitable position.
[0007] The upper end circumference of the guide shaft is formed with an annular chamfer, which can easily make the misplaced pipe parts fall off.
[0008] Compared with the prior art, the advantage of the utility model lies in that the angle of the anti-error base on the adjusting mounting seat is adjusted to a suitable inclination angle through the angle adjustment mechanism, and the guide shaft is moved in the central through hole to adjust the length of the part of the upper end of the guide shaft extending out of the anti-error base. After the adjustment, the guide shaft is fixed in the anti-error base through the locking mechanism, and different inclination angles of the anti-error base on the adjusting mounting seat and the lengths of the guide shaft extending out of the anti-error base can be set according to different pipe parts, so that pipe parts placed in the wrong direction cannot be stably mounted on the guide shaft and fall off due to the outward center of gravity, so that only pipe parts placed in the correct position will not fall off, and pipe parts that are not designated products or in incorrect postures will fall off, saving manpower and material costs and improving production efficiency.

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] like Figures 1 to 4 As shown, an anti-error positioning mechanism for a pipe part comprises an adjustment mounting seat 1, an angle adjustment mechanism, a guide shaft 3 and an anti-error base 4 having a central through hole 41. The anti-error base 4 is tiltedly arranged on the adjustment mounting seat 1 through the angle adjustment mechanism, the guide shaft 3 extends downward into the central through hole 41, a locking mechanism for locking the position of the guide shaft 3 is arranged between the guide shaft 3 and the anti-error base 4, and an annular positioning groove 42 is arranged in a recessed manner around the guide shaft 3 on the upper part of the anti-error base 4;
[0015] In this embodiment, the angle adjustment mechanism includes a first locking bolt 21 and a second locking bolt 22. A rotation hole 11 and an arc-shaped adjustment hole 12 are provided on the adjustment mounting seat 1. The rotation hole 11 is obliquely above the arc-shaped adjustment hole 12. A first positioning hole 43 corresponding to the rotation hole 11 and a second positioning hole 44 corresponding to the arc-shaped adjustment hole 12 are provided on the anti-mistake base 4. The first locking bolt 21 passes through the rotation hole 11 from outside to inside and extends into the first positioning hole 43. The second locking bolt 22 passes through the arc-shaped adjustment hole 12 from outside to inside and extends into the second positioning hole 44.
[0016] In this embodiment, the locking mechanism includes a positioning screw 51 and a positioning screw hole 45 provided on the anti-error base 4. The positioning screw 51 is screwed inwardly into the positioning screw hole 45 and is pressed against the guide shaft 3.
[0017] In this embodiment, an annular chamfer 31 is formed on the circumferential side of the upper end of the guide shaft 3;
[0018] The working principle is as follows: taking the placement of nuts with large and small heads as an example, the angle of the anti-mistake base 4 on the adjustment mounting seat 1 is adjusted to a suitable inclination angle by the first locking bolt 21 and the second locking bolt 22, and the size of the annular positioning groove 42 matches the size of the small head of the nut, so that the guide shaft 3 is moved in the central through hole 41 to adjust the length of the part of the upper end of the guide shaft 3 extending out of the anti-mistake base 4. After adjustment, the positioning screw 51 is screwed inwardly into the positioning screw hole 45 and tightened on the guide shaft 3 to fix the guide shaft 3 in the anti-mistake base 4. Therefore, when the small head of the nut is placed on the annular positioning groove 42, the nut will not fall off; and the outer diameter of the large head of the nut is larger than the maximum inner diameter of the annular positioning groove 42, so it cannot be placed in the annular positioning groove 42, and by reasonably setting the inclination angle of the anti-mistake base 4 and the length of the guide shaft 3 extending out of the anti-mistake base 4, the nut placed in the wrong direction can fall off because the center of gravity is biased outward and it cannot be stably mounted on the guide shaft 3.
