Description

Technical Field

[0001] This utility model relates to the field of central tool AGV automatic tool change technology, specifically a central tool magazine system for AGV automatic tool change. Background Technology

[0002] In flexible manufacturing systems, AGV automatic tool changers are the core hub connecting tool storage and machining equipment. Rail-mounted mobile vehicles, in conjunction with automated tool-changing robotic arms, place automatically removed old tools into waiting tool holders, and then replace them with alternative tools at specific workstations after tool removal. The efficiency of tool changing operations directly affects the production line's utilization rate. As precision machining places higher demands on tool condition, tool wear detection in the tool changing process has become crucial for ensuring machining quality.

[0003] However, existing AGV tool changing devices generally lack online tool detection solutions, making it difficult to obtain real-time information on tool wear, service life, and other status information. This can easily lead to workpiece scrap due to tool failure during processing. Furthermore, tool life status relies on manual inspection, resulting in low levels of intelligence. In addition, some simple portable detection mechanisms have fixed detection positions that can be flexibly adjusted according to tool type and length, which can easily lead to blind spots in the detection perspective and result in inaccurate wear assessments. Therefore, there is an urgent need for a central tool magazine system for AGV automatic tool changing to solve the above problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-3 This utility model provides an AGV automatic tool changer central tool magazine system, including a track-mounted mobile vehicle body 1, a robotic arm 2 fixedly connected to the top surface of the track-mounted mobile vehicle body 1, a clamping mechanism 3 fixedly connected to the end of the robotic arm 2, and further including: The detection component is fixedly connected to the side wall of the clamping mechanism 3 and is used to perform visual inspection on the tool clamped by the clamping mechanism 3. An adjustment component is located on the inner wall of the detection component and is used to adjust the detection position of the detection component. The detection components facilitate visual inspection and wear assessment of the tools held by the clamping mechanism 3, thereby enabling analysis of tool life and reducing the probability of workpiece scrap due to excessive tool wear. Simultaneously, the adjustment components allow for easy adjustment of the detection position, improving detection accuracy and wear determination precision. The track-moving vehicle body 1 and the clamping mechanism 3 are common fixed-track moving parts and tool clamping parts in the prior art, possessing automatic movement along a planned track and automatic tool changing functions according to a set tool changing process. The track-moving vehicle body 1 and the clamping mechanism 3 are considered prior art in this application and will not be described in detail here.

[0016] Furthermore, the detection component includes a fixing frame 401, which is fixedly connected to the side wall of the clamping mechanism 3. The side wall of the fixing frame 401 has a sliding hole 402, and a sliding plate 403 is slidably connected to the inner wall of the sliding hole 402. A vision camera 404 is provided on the side wall of the sliding plate 403, and a controller 405 is fixedly connected to the inner wall of the fixing frame 401. The vision camera 404 and the controller 405 are electrically connected. Through the detection component, it is convenient to visually inspect the tool when the clamping mechanism 3 grasps the tool. After the inspection by the vision camera 404, the vision camera 404 and the controller 405 work together to judge the wear of the tool, thereby facilitating the analysis of the tool's service life and reducing the probability of workpiece scrap caused by excessive tool wear.

[0017] Furthermore, the adjustment assembly includes a threaded post 501, which is rotatably connected to the inner wall of the sliding hole 402. The top surface of the sliding plate 403 has a threaded hole 502. The surface of the threaded post 501 is threadedly connected to the inner wall of the threaded hole 502. The top surface of the sliding plate 403 has a sliding groove 503. A sliding frame 504 is slidably connected to the inner wall of the sliding groove 503. The inner wall of the sliding frame 504 is fixedly connected to the surface of the vision camera 404. The sliding frame 504 and the sliding plate 403 are detachably connected by bolts. A fixing nut 505 is threadedly connected to the surface of the threaded post 501. The upper end of the fixing nut 505 abuts against the bottom surface of the fixing frame 401. Through the adjustment assembly, when the threaded post 501 rotates, it drives the sliding plate 403 to move. The movement of the sliding plate 403, in turn, drives the sliding plate 403 to move. The plate 403 moves to facilitate adjustment of the detection position of the vision camera 404, thereby improving detection accuracy and the precision of wear determination. The sliding groove 503 and the sliding frame 504 work together to facilitate adjustment of the detection distance between the vision camera 404 and the tool, thereby improving adjustment flexibility. The fixing nut 505, when rotated clockwise, abuts against the bottom surface of the fixing frame 401. The friction between the fixing nut 505, the threaded post 501, and the fixing frame 401 facilitates the constraint and fixation of the threaded post 501, thereby improving the stability of the threaded post 501 during use.

[0018] Furthermore, a storage battery 406 is fixedly connected to the inner wall of the main body 1 of the track-moving vehicle. The storage battery 406 is electrically connected to the controller 405 and the vision camera 404. The storage battery 406 facilitates the provision of independent power to the controller 405 and the vision camera 404, ensuring the stability of the controller 405 and the vision camera 404 during use.

[0019] Working principle: During use, the set detection components make it easy to visually inspect the tool when the clamping mechanism 3 grabs the tool. After the inspection by the vision camera 404, the vision camera 404 and the controller 405 work together to judge the wear of the tool, thereby making it easier to analyze the tool's service life and reduce the probability of workpiece scrapping caused by excessive tool wear.

[0020] Meanwhile, the adjustable components allow the threaded column 501 to rotate, causing the sliding plate 403 to move. The movement of the sliding plate 403 facilitates the adjustment of the detection position of the vision camera 404, thereby improving detection accuracy and the precision of wear determination.
