Select round pin mechanism simple structure, convenient operation through the cooperation of dog and feed opening, when exceeding the dog and injecing the height, leads to the silo with round pin axle discharge through the dog guide, and the ingenious restriction that utilizes to round pin axle length realizes the classification to the round pin axle.
Description
Technical Field
The utility model relates to a select round pin mechanism.
Background
The pin shaft is used as a connecting piece of the chain, and the required length of the pin shaft is different according to the size of the chain; since the pin is obtained by cutting a long steel wire, a machining error inevitably occurs, and therefore, it is necessary to select a pin having a corresponding length before use.
SUMMERY OF THE UTILITY MODEL
To the defect that prior art exists above, the utility model discloses a main aim at overcomes prior art's weak point, discloses a select round pin mechanism, including selecting round pin body, height adjusting mechanism and dog, select the round pin body go up the concave silo that leads to that establishes the open-type and link up, the one side interval of selecting the round pin body sets up two feed openings, two height adjusting mechanism sets up select on the round pin body, the dog sets up height adjusting mechanism is last, utilizes height adjusting mechanism adjusts the high position of dog, just the dog is located the top of feed opening.
Further, height adjusting mechanism includes a body, adjusting bolt and spring, the vertical guide slot that sets up of body, adjusting bolt sets up in the guide slot, just the spring with the dog sets up on the adjusting bolt, the spring action in the upper end of guide slot with on the dog, utilize the guide slot guide with the restriction the dog vertical movement.
Further, the feed opening is in a right-angle trapezoid shape.
The utility model discloses the beneficial effect who gains:
select round pin mechanism simple structure, convenient operation through the cooperation of dog and feed opening, when exceeding the dog and injecing the height, leads to the silo with round pin axle discharge through the dog guide, and the ingenious restriction that utilizes to round pin axle length realizes the classification to the round pin axle.
Drawings
Fig. 1 is a schematic structural view of a pin selecting mechanism of the present invention;
the reference numbers are as follows:
21. the pin selecting device comprises a pin selecting body 22, a height adjusting mechanism 23, a stop block 24, a material passing groove 25, a feed opening 221, a block body 222, an adjusting bolt 223, a spring 224 and a guide groove.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
The pin shafts are divided into three types, including a long pin shaft (a pin shaft higher than the standard length range), a short pin shaft (a pin shaft shorter than the standard length range), and a standard pin shaft (a pin shaft located within the standard range).
A pin selecting mechanism is shown in figure 1 and comprises a pin selecting body 21, a height adjusting mechanism 22 and a stop dog 23, wherein an open through material passing groove 24 is concavely formed in the pin selecting body 21, two feed openings 25 are formed in one side of the pin selecting body 21 at intervals, the two height adjusting mechanisms 22 are arranged on the pin selecting body 21, the stop dog 23 is arranged on the height adjusting mechanism 22, the height position of the stop dog 23 is adjusted by the height adjusting mechanism 22, and the stop dog 23 is positioned above the feed openings. Wherein, dog 23 on right side is adjusted to the maximum value of standard round pin axle length, and left dog 23 is adjusted to the minimum value of standard round pin axle length, and the round pin axle is arranged in proper order from the right-hand member that leads to silo 24 and is got into, and when the right side feed opening 25 was passed through, if round pin axle length overlength, received dog 23's blockking to the guide round pin axle leaves from feed opening 25 and leads to silo 24. At the moment, the short pin shaft and the standard pin shaft pass through the right-side stop block 23, if the length of the pin shaft is within the standard range, the pin shaft is stopped by the left-side stop block 23, and the pin shaft is discharged from the left-side feed opening in the same way; only the short pin shafts can pass through and leave from the left end of the through trough 24, and then classification of the pin shafts with three specifications is achieved.
In one embodiment, as shown in fig. 1, the height adjusting mechanism 22 includes a block body 221, an adjusting bolt 222 and a spring 223, the block body 221 is vertically provided with a guide groove 224, the adjusting bolt 222 is provided in the guide groove 224, the spring 223 and the stopper 23 are provided on the adjusting bolt 222, the spring 223 acts on the upper end of the guide groove 224 and the stopper 23, and the guide groove 224 is used for guiding and limiting the stopper 23 to vertically move; that is, the adjusting bolt 222 is screw-engaged with the stopper 23, and when the adjusting bolt 222 is rotated, the stopper 23 is restricted from following the rotation by the guide groove, and moves up and down according to the angle of rotation of the adjusting bolt 222 to adjust the height position thereof.
In one embodiment, as shown in FIG. 1, the feed opening 25 is in the shape of a right-angled trapezoid.
The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
