Example 2:
the present embodiment relates to a lock, and reference may be made to the technical scheme in the chinese patent of utility model with bulletin number of CN 202152576U. Specifically, the lock related to the scheme comprises a blade described in embodiment 1. Due to the adoption of the blades, automatic screening and sorting can be achieved based on the blades, and therefore assembly efficiency is improved.
Example 3:
As shown in fig. 2 to 6, the present embodiment relates to an apparatus for screening and arranging one of the blades described in embodiment 1. In particular, the device comprises a selection track 2 with a conveying direction from high to low, and a vibrating disk for driving the blades to be conveyed on said selection track 2. The section of the material selecting track 2 is obliquely downwards arranged to one side, and a flange 21 is arranged at the lower end of the oblique direction of the material selecting track 2. The conveying path of the material selecting track 2 is provided with screening openings 22, and in the specific embodiment shown in the figure, the material selecting track 2 is provided with two or more screening openings 22, and the accuracy of blade screening is ensured by arranging the two or more screening openings 22.
The caliber of any position of the screening opening 22 in the width direction of the material selecting track 2 is larger than the distance between the corresponding blade outer edge and the nearest key hole 11 side wall, when the caliber of one position of the screening opening 22 in the width direction of the selected material selecting track 2, such as position A, is d1, and the distance between the blade outer edge of the position A and the nearest key hole 11 side wall is d2, wherein d1 is larger than d2. The downstream edge of the screening opening 22 is close to one side of the baffle plate to form a first supporting plate 23, and the minimum vertical distance d3 between the first supporting plate 23 and the upstream edge of the screening opening 22 is smaller than the maximum vertical distance d4 between the protrusion 13 on the blade and the nearest side wall of the keyhole 11, wherein d4 refers to the distance between the nearest side wall of the keyhole 11 and the farthest end of the protrusion 13. The upstream edge of the screening opening 22 is inclined from one side of the flange 21 to the other side, and is inclined in the downstream direction of the conveying direction of the material selecting rail 2. Such that the upstream edge of the screening opening 22 forms a second pallet 24 on the side remote from the baffles.
The technical proposal relates to a device for screening blades, which comprises a material selecting rail 2 with a conveying direction from a high place to a low place and a vibrating disk for driving the blades to be conveyed on the material selecting rail 2. When the device is used, the blades which are in disorder order are poured into the vibration disc, and the blades are output to the material selecting track 2 along with the vibration of the vibration disc and are conveyed from high to low through the material selecting track 2. The section of the material selecting rail 2 is inclined downwards to one side, and a flange 21 is arranged at the lower end of the material selecting rail 2 in the inclined direction. The blade is made to always contact the flange 21 during the transport along the selection track 2. When the arc part of the outer edge of the blade contacts the flange 21, the blade can rotate in the conveying process due to the vibration effect, and the blade cannot rotate in the conveying process until the straight tangent plane 14 on the blade is attached to the flange 21. Finally, the straight cut surface 14 of the blade at the upstream of the screening opening 22 always adheres to the flange 21, and only two states (one of which is the needle roller groove 12 facing forward and the other of which is the projection 13 facing forward) are included, and the screening opening 22 only needs to screen the two states. Specifically, the caliber of any position of the screening opening 22 in the width direction of the material selecting track 2 is larger than the distance between the outer side edge of the corresponding blade and the nearest side wall of the key hole 11. As shown in fig. 2 and 3, when the needle roller grooves 12 are directed forward, the blade portions on the front side of the key hole 11 are located at the screening openings 22, and the blade is inclined by gravity due to the fact that the portions are not supported, and finally fall, i.e., are screened out. And since the downstream edge of the screening opening 22 is formed with the first pallet 23 on the side close to the baffle plate, the minimum vertical distance between the first pallet 23 and the upstream edge of the screening opening 22 is smaller than the maximum vertical distance between the protrusion 13 on the blade and the closest sidewall of the keyhole 11. As shown in fig. 4 and 5, when the boss 13 is directed forward, the boss 13 on the vane is already supported by the first pallet 23 when the vane portion on the front side of the key hole 11 has not completely entered the screen port 22 (has not been separated from the support of the second pallet 24 on the upstream edge of the screen port 22), and the vane can smoothly pass through the screen port 22 in this state, i.e., is retained by the screen. Finally, the sorting and screening of the blades are realized through the device, and the device only comprises the blades with the straight tangent planes 14 attached to the flanges 21 and the protrusions 13 facing forward. The blade can be screened and ordered by adopting the assembly and matching with the blade, so that the technical bottleneck of automatic assembly of the blade lock is solved, and the automatic assembly of the blade lock is feasible.
In a further scheme, the tail end of the material selecting track 2 is provided with a feed opening, and a material stringing rod for stringing the screened blades is arranged below the feed opening.
