Description

Technical Field

[0001] This invention relates to a visual error detection device, and more specifically, to a camera device, a cable connection device, and a control method. Background Technology

[0002] Aerospace structural components, due to their lightweight, high specific strength, and compact spatial structure, are widely used in next-generation aerospace vehicles. Thin-walled parts such as integral frames, integral panels, and large frame beams are primarily machined using milling for material removal. However, the high material removal rate during aerospace structural component machining reduces the relative stiffness of the formed components, making them prone to cutting vibration and elastic deformation during processing. This compromises dimensional accuracy and surface quality, impacting machining efficiency and manufacturing costs. Therefore, quality inspection is required after each machining step. Furthermore, the complex characteristics and multiple inspection elements of aerospace structural components necessitate transferring the machined parts from the workbench to an inspection platform for testing various factors such as wall thickness, hole diameter, and wall distance. Manual inspection is susceptible to subjective factors, leading to poor measurement accuracy and significant time costs. While visual error detection technology is maturing and many new devices are equipped with cameras for inspection, older models lack dedicated visual inspection devices. Therefore, a device that facilitates upgrading older models is needed. Summary of the Invention

[0033] Example:

[0034] This embodiment provides a camera device 2, which can be used to improve an existing milling machine 10 without a vision inspection device, enabling it to have vision inspection capabilities.

[0035] The camera device 2 includes a camera 23; the camera device 2 is used to cooperate with the spindle 11 of the milling machine 10; it also includes a camera 23 bracket 22; the camera 23 is fixed on the camera 23 bracket 22; one end of the bracket is connected to the tool holder 21, and the tool holder 21 is used to connect to the spindle 11 of the milling machine 10.

[0036] The tool holder 21 is mounted on the camera 23 bracket 22, and the camera 23 bracket 22 can be directly connected to the spindle 11 of the milling machine 10 via the tool holder 21. Alternatively, the camera device 2 can be placed inside the tool magazine 14, and can be mounted on the spindle 11 of the milling machine 10 via the tool changing mechanism 13, thus achieving automatic mounting of the camera device 2. This solution provides a convenient way to provide visual inspection functionality for equipment without a visual inspection device.

[0037] In one possible embodiment, the camera 23 has power supply and wireless transmission capabilities, and can transmit photos or videos to the outside world.

[0038] It also includes an outward-facing interface 24; the outward-facing interface 24 and the tool holder are in a T-shape configuration; the outward-facing interface 24 and the camera 23 are located on opposite sides of the tool holder, and this arrangement prevents the camera 23 from being touched or damaged during cable insertion. A lens fixing clip is provided on the camera 23 bracket 22; the lens fixing bracket 25 is located in front of the camera 23 shutter; it is used to fix the lens. The outward-facing interface 24 is used to connect external components to achieve data transmission and power supply. The lens is a telecentric lens 26. The telecentric lens 26 can achieve better shooting results and is used for post-processing visual algorithm analysis.

[0039] This embodiment provides a cable connection device that cooperates with the above-mentioned camera device 2, and is used to be installed on the milling machine 10; the cable device includes a cable connector 35; the cable connector 35 cooperates with the outward interface 24;

[0040] It also includes a linear slide rail 30, a first connecting arm 31, a second connecting arm 32, and a third connecting arm 33;

[0041] The first connecting arm 31 is connected to the slider of the linear slide rail 30; the first connecting arm 31 and the second connecting arm 32 can be bent in a controlled manner; the second connecting arm 32 and the third connecting arm 33 can be bent in a controlled manner; the third connecting arm 33 is provided with a clamping mechanism 34; the clamping mechanism 34 is used to clamp the cable connector 35.

[0043] Furthermore, the third connecting arm 33 has a third bend at one end near the second connecting arm 32; the second connecting arm 32 is hinged to the third connecting arm 33; it also includes a second push rod, one end of which is hinged to the second connecting arm 32 and the other end of which is connected to the third bend.

Conversely, extending the push rod results in a retracting effect. By incorporating movable parts, the two arms can be brought as close together as possible. The retraction of the two arms reduces space requirements and avoids interfering with the operation of other machine tools.

In the figure, electric push rod 1 is the first push rod 42, and electric push rod 2 is the second push rod. The stroke of the electric push rods controlled by the microcontroller is constant, and after the tool change mechanism, the position of the camera device 2 is also relatively constant, thus ensuring that the cable connector 35 can be smoothly inserted into the external interface 24.
