The current blade padlock can refer to the content recorded in the prior patent background technology with announcement number "CN211622993U", including the lock body and lock beam. The processing steps of this type of blade padlock are generally: drilling holes in the blank, installing pins and blind heads, polishing, installing lock beams, steel balls and lock cores, and then pressing and installing blind covers to seal the lock core in the lock core hole. Among them, the holes opened on the blank include lock beam holes, lock core holes, pin holes, and steel ball assembly holes that connect the lock beam holes and the lock core holes for loading steel balls.

[0003] Furthermore, the above-mentioned prior patent records a steel ball assembly device for a blade padlock, comprising a lock body clamp for clamping and fixing the lock body, and a lock beam assembly component for pressing the lock beam arm of the lock beam into the lock beam hole of the lock body, and a hollow shaft having a steel ball conveying channel for the steel balls to pass through, and a top steel ball assembly for pressing the steel balls inside the hollow shaft into the steel ball assembly hole of the lock body; a bending portion is provided at the outer end of the hollow shaft so that the terminal end of the steel ball conveying channel of the hollow shaft can be aligned with the steel ball assembly hole on the inner wall of the lock body; at least one of the lock body clamp and the hollow shaft can move axially along the hollow shaft, and at least one can rotate circumferentially along the hollow shaft.

[0004] When the above-mentioned steel ball assembly device is assembled, the lock body is first fixed by the lock body clamp; then the lock beam is installed into the lock beam hole of the lock body through the lock beam assembly assembly; then the lock body clamp or the hollow shaft moves axially along the hollow shaft, the hollow shaft extends into the lock core hole of the lock body and the end of the steel ball conveying channel is aligned with one of the steel ball assembly holes on the inner wall of the lock body, and the steel ball pushing assembly pushes the last steel ball into the steel ball assembly hole of the lock body; finally, the hollow shaft or the lock body clamp rotates 180°, so that the end of the steel ball conveying channel is aligned with another steel ball assembly hole on the inner wall of the lock body, and the steel ball pushing assembly pushes the last steel ball into the steel ball assembly hole of the lock body, completing the steel ball assembly.

[0005] The above-mentioned steel ball assembly device requires the hollow shaft or the lock body fixture to rotate 180 degrees to complete the installation of the steel balls on both sides. Its assembly structure and control part are relatively complicated and prone to errors. Summary of the invention

The steel ball installation mechanism is equipped with two sets of steel ball installation components and two sets of steel ball feeding components. The steel ball installation components include steel ball guide tubes and steel ball pushing components. The steel ball feeding components feed steel balls into the steel ball guide tubes of the steel ball installation components. The steel ball guide tubes are used to transport the steel balls downward to the outlet of the guide tubes. When in use, based on the relative operation of the lock body and the steel ball guide tube [which can be the lock body or the steel ball guide tube], the steel ball guide tube extends into the lock core hole of the lock body, and the steel ball pushing component presses the steel balls at the outlet of the guide tube into the steel ball assembly hole to complete the assembly of the steel balls on one side.

In this scheme, the steel ball pushing component is selected as a steel ball push piece, which, on the one hand, serves as a part of the steel ball guide tube and is used to block the push piece groove; on the other hand, the steel ball assembly cylinder can be arranged on one side of the upper end of the steel ball guide tube, which can also realize the pushing of the steel ball at the bottom of the steel ball guide tube.

[0015] In a specific embodiment, the steel ball feeding assembly includes a steel ball feeding tube and a steel ball feeding cylinder for pushing the steel balls in the steel ball feeding tube into the steel ball guide tube. In this scheme, after the steel balls enter the steel ball feeding tube from the feeding track, the steel ball feeding cylinder pushes the steel balls into the steel ball guide tube.

[0027] like Figure 1 and 2As shown in Figure 3, this embodiment relates to a steel ball installation device, including two sets of steel ball feeding assemblies and two sets of steel ball installation assemblies arranged on the installation plate 1. The steel ball installation assembly includes a steel ball guide tube 21 for conveying steel balls downward, a steel ball pushing component 22 for embedding in the steel ball guide tube 21, a pushing rod 23 for pushing steel balls along the steel ball guide tube 21, a pushing cylinder 24 for driving the pushing rod 23, and a pushing bracket 25 for installing the pushing cylinder 24. The pushing bracket 25 is equipped with a pushing cylinder 24, and the pushing rod 23 is connected to the output end of the pushing cylinder 24. The steel ball feeding assembly feeds steel balls into the steel ball guide tube 21 below the pushing rod 23, and the pushing rod 23 moves downward to push the steel balls along the steel ball guide tube 21 to the guide tube outlet 211. In this solution, a push rod 23 is used to press down the steel ball, so that the steel ball moves along the steel ball guide tube 21 to the guide tube outlet 211.

[0028] The two sets of steel ball feeding assemblies respectively feed steel balls into the steel ball guide tubes 21 of the two sets of steel ball installation assemblies. In a specific embodiment, the steel ball feeding assembly includes a steel ball feeding tube 31, and a steel ball feeding cylinder 32 for pushing the steel balls in the steel ball feeding tube 31 into the steel ball guide tube 21. In this scheme, after the steel balls enter the steel ball feeding tube 31 from the feeding track, the steel ball feeding cylinder 32 pushes the steel balls into the steel ball guide tube 21.

[0029] like Figure 1 As shown, the lower ends of the steel ball guide tubes 21 on the two sets of steel ball installation assemblies are respectively constructed with guide tube outlets 211 facing opposite directions, and the steel ball pushing components 22 are used to push the steel balls in the steel ball guide tubes 21 out of the guide tube outlets 211. The steel ball pushing component 22 is a steel ball pusher, which is connected to the steel ball assembly cylinder. The steel ball guide tube 21 on the opposite side of the outlet of the steel ball guide tube 21 is provided with a pusher groove arranged along its axial direction, and the steel ball pusher is movably embedded in the pusher groove, and the lower end of the steel ball pusher extends to the plane where the guide tube outlet 211 is located. In this scheme, the steel ball pushing component 22 is selected as a steel ball pusher, which, on the one hand, serves as a part of the steel ball guide tube 21 and is used to block the pusher groove. On the other hand, the steel ball assembly cylinder 26 can be arranged on one side of the upper end of the steel ball guide tube 21, which can also realize the pushing of the steel balls at the bottom of the steel ball guide tube 21.

[0030] In the above scheme, the steel ball installation mechanism is equipped with two sets of steel ball installation components and two sets of steel ball feeding components. The steel ball installation components include a steel ball guide tube 21 and a steel ball pushing component 22. The steel ball feeding component feeds steel balls into the steel ball guide tube 21 of the steel ball installation component. The steel ball guide tube 21 is used to convey the steel balls downward to the guide tube outlet 211. When in use, based on the relative operation of the lock body 10 and the steel ball guide tube 21 [which can be the lock body 10 or the steel ball guide tube 21], the steel ball guide tube 21 extends into the lock core hole 100 of the lock body 10, and the steel ball pushing component 22 presses the steel balls at the guide tube outlet 211 into the steel ball assembly hole 101, completing the assembly of the steel balls on one side.

[0031] Then, after the steel ball guide tube 21 is withdrawn from the lock core hole 100 of the lock body 10, the steel ball guide tube 21 of the other set of steel ball installation components is aligned with the lock core hole 100 of the lock body 10 based on the horizontal movement of the steel ball installation device or the horizontal movement of the lock, and the steel balls on the other side are installed in the same way as above until the steel balls on both sides are assembled. Figure 1 As shown, the mounting plate 1 is provided with a steel ball assembly moving pair, and the steel ball feeding assembly and the steel ball installation assembly are both installed on the steel ball assembly moving pair. And the steel ball guide tubes 21 on the two groups of steel ball installation assemblies are arranged along the moving direction of the steel ball assembly moving pair. In the scheme here, a steel ball assembly moving pair 4 is provided on the mounting plate 1, and then the steel ball feeding assembly and the steel ball installation assembly are both installed on the steel ball assembly moving pair 4. In this way, when one group of steel ball installation assemblies completes the installation of steel balls on one side of the lock, the steel ball assembly moving pair 4 moves to the steel ball guide tube 21 of another group of steel ball installation assemblies and aligns with the lock core hole 100 of the lock body 10 to complete the installation of the steel balls on the other side. In a specific implementation scheme, the steel ball assembly moving pair 4 includes a slide rail 41 arranged on the mounting plate 1, a movable plate 42 arranged on the slide rail 41, and a driving cylinder 43 that drives the movable plate 42 to move along the slide rail 41.

[0032] In summary, the process of the steel ball installation device is as follows: after the lock body 10 is fixed on the fixture, the steel ball guide tube 21 of one set of steel ball installation components is aligned with the lock core hole 100 of the lock body 10, and the fixture for fixing the lock body 10 moves upward to extend the steel ball guide tube 21 into the lock core hole 100 of the lock body 10. The first set of steel ball feeding components feeds steel balls into the steel ball guide tube 21 of the first set of steel ball installation components, and the push rod 23 moves downward to push the steel balls along the steel ball guide tube 21 to the guide tube outlet 211, and the steel ball pusher presses the steel balls from the guide tube outlet 211 into the steel ball assembly hole 101 under the action of the steel ball assembly cylinder 26, completing the assembly of the steel balls on one side.

[0033] Then, the upper movement of the clamp fixing the lock body 10 causes the steel ball guide tube 21 to exit the lock core hole 100 of the lock body 10, and the steel ball assembly moving pair 4 moves to align the steel ball guide tube 21 of the second set of steel ball installation components with the lock core hole 100 of the lock body 10, and the installation of the steel ball on the other side is completed in the same manner as above. The above steel ball installation device uses two sets of steel ball installation components to respectively assemble the steel balls on both sides, which has the advantages of simplified structure and less prone to errors compared to the above background technology solution.
