Detailed Description
Examples are shown in fig. 1 and 2: and a device for automatically pressing and riveting the steel balls, which is used for pressing the steel balls into a workpiece on an assembly fixture 100 and riveting the workpiece.
Specifically, the automatic steel ball pressing and riveting device comprises: the hydraulic device comprises an oil cylinder 10, a connecting piece 20, a spring 30, a push rod 40, a movable seat 50, a riveting head 60 and the like.
Wherein:
the cylinder 10 is fixed to the assembly jig 100 by bolting or the like, and the telescopic shaft 11 of the cylinder 10 extends leftward.
As shown in fig. 3, the right part of the connector 20 is provided with a connecting hole 21 opened to the right, and the left part of the connector 20 is provided with an insertion part 22. The insertion portion 22 may be formed such that the insertion portion 22 has a smaller cross section than the right portion of the connection member 20, thereby forming a step at the right end of the insertion portion 22. Meanwhile, the left end face of the connection hole 21 has a fitting hole 23 extending leftward to the left end face of the insertion portion 22.
The right end of the spring 30 is fixed and sleeved on the insertion portion 22. The term "fixed" as used herein mainly means that the spring 30 is fitted over the insertion portion 22, and the right end of the spring 30 is supported. For example, the right end of the spring 30 is supported on a step at the right end of the insertion portion 22.
The right end of the push rod 40 has a large head 41 having a diameter smaller than the inner diameter of the connection hole 21 but larger than the inner diameter of the fitting hole 23. That is, the ejector pin 40 resembles a screw that is unthreaded but has a large head.
As shown in fig. 4, the movable base 50 is provided with a through hole 51 extending in the left-right direction. The perforation 51 includes a large diameter portion 511 at the right portion and a small diameter portion 512 at the left portion. That is, the through hole 51 has a reverse "convex" shape with a small left and a large right as seen in a longitudinal section. Meanwhile, a steel ball inlet 5121 is provided on the side wall of the small diameter portion 512, and the steel ball inlet 5121 is connected with a feeding device 52. That is, the steel ball enters the small diameter portion 512 from the steel ball inlet 5121 via the feeding device 52.
The rivet head 60 is fixed to the left side surface of the movable seat 50, and a communication hole 61 communicating with the small diameter portion 512 is provided at the center position of the rivet head 60.
More specifically:
the connecting hole 21 is screwed on the telescopic shaft 11.
The ejector pin 40 is inserted into the mating hole 23 from right to left, and the left end of the ejector pin 40 is located at the left of the insertion portion 22. That is, the jack 40 is fixed to the telescopic shaft 11 of the cylinder 10 through the connection member 20.
The large diameter portion 511 is fitted to the left end of the spring 30, the small diameter portion 512 is fitted to the ejector 40, and the small diameter portion 512 is fitted to the communication hole 61. That is, the left end of the spring 30 can enter the large diameter portion 511 and can be supported by the left end surface of the large diameter portion 511; the push rod 40 can pass through the small diameter portion 512 and the communication hole 61 from right to left.
Thus, in use, the cylinder 10 is actuated and the telescopic shaft 11 extends to the left to move the connecting member 20 to the left. At the same time, the steel ball is already located in the small diameter portion 512. The ejector rod 40 and the spring 30 are both moved leftward by the driving of the connector 20. The spring 30 enters the large diameter portion 511 to urge the movable seat 50 leftward, and the rivet head 60 abuts against the workpiece to prevent the workpiece from moving. The plunger 40 then continues to move to the left, and the compression spring 30 is in a gradually compressed state. After the ejector rod 40 continues to move, the steel ball is ejected into the workpiece. After the spring 30 is fully compressed, the left end of the insertion portion 22 is pushed against the left end surface of the large diameter portion 511, and the caulking head 60 can fully apply force to the workpiece, thereby caulking the workpiece.
Optimizing:
the movable base 50 is fixed on a slider 70, the slider 70 is slidably disposed on a wire gauge 80, and the wire gauge 80 is fixed on the assembly fixture 100. That is, the movement of the movable base 50 can be ensured to move right and left along a correct trajectory.
A spring plunger 5122 is provided on the side wall of the small diameter portion 512 on the left side of the position of the steel ball inlet 5121. Namely, the spring plunger 5122 limits the steel ball, and prevents the steel ball from falling out automatically.
Continuing to optimize:
a linkage rod 91 is fixed on the telescopic shaft 11, the linkage rod 91 is provided with a travel switch 92, and a PLC (not shown in the figure) is connected to the travel switch 92 through a signal, and the PLC signal is connected to the oil cylinder 10. Namely, the action of the oil cylinder 10 is controlled by the PLC, so that the automatic steel ball pressing and riveting device has a certain degree of automation, and the manual participation degree is further reduced.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
