Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automated production and automated production equipment, and specifically, it is a vision-guided hole automatic closing device. Background Art
[0002] Currently, in the assembly of parts and pins, the main methods to prevent the pin from falling out of the part are as follows: one is the interference fit between the part hole and the pin. This requires very high fitting accuracy between the part hole and the pin. If the fitting clearance is too large, the pin is likely to fall off. If the interference fit is too large, it is difficult to assemble the pin and there is even a risk of damaging the part; the other is that the operator uses an appropriate tool to knock out a circular closing at the hole port, and the pin is axially restricted by the circular closing in the pin hole.
[0003] Among them, when the operator uses an appropriate tool to knock out a circular closing at the hole port, the operator needs to pay attention to the force control during the production of the circular closing. It is necessary to ensure that the pin hole mouth starts to close, and at the same time, avoid damaging the part due to excessive force. It not only requires the operator to have solid professional knowledge and proficient operation skills, but also requires in-depth understanding of the materials and tools used.
[0004] Therefore, it is necessary to provide a vision-guided hole automatic closing device to solve the above problems. Content of the Utility Model

A vertical motion mechanism is arranged on the plane of the parallel motion mechanism. A closing tool and a 3D vision module are fixedly arranged on the side panel of the vertical motion mechanism;
[0008] The 3D vision module is used as a real-time detection actuator to guide the coordinated movement of the parallel motion mechanism and the vertical motion mechanism, so that the closing tool of the closing tool is aligned with the assembly pin hole mouth, and concave and convex marks are formed by extrusion on the inner wall of the end face hole of the assembly pin hole, forming a vision-guided hole automatic closing structure.
[0009] Further, the parallel motion mechanism includes a parallel mechanism drive motor. The parallel mechanism drive motor is connected with a parallel ball screw, and a parallel linear guide rail is correspondingly arranged for the parallel ball screw.
[0010] Further, the parallel motion mechanism further includes a protective cover.
[0011] Further, the vertical motion mechanism includes a vertical mechanism bracket, on which a vertical mechanism motor is provided. The vertical mechanism motor is connected to a vertical ball screw, and a vertical linear guide is provided corresponding to the vertical ball screw.

[0013] Further, the 3D vision module guides the coordinated movement of the parallel motion mechanism and the vertical motion mechanism, so that the tool power mechanism and the assembled pin hole are on the same axis.
