Abstract
Description
Technical Field
[0001] This utility model relates to the field of robot tool changing technology, specifically a robot tool quick changing mechanism. Background Technology
[0002] In automated processing, tools need to be changed, so a robotic tool changer is required.
[0003] Chinese patent CN117260786A discloses a quick-change device for robot tools, comprising: a track; a skid disposed on the track and reciprocating on the track; and a tool tray disposed on the skid, including at least two sets of quick-attachment points for supporting robot tools. A method for quick-change of robot tools is also proposed. This patent provides a quick-change device and method for robot tools in welding production workshops, which can not only replace manual handling, eliminating the difficulties and safety hazards associated with manual tool handling, but also enable automatic quick tool changing through robot operation. This patent eliminates the need for manual handling of robot tools, featuring low labor intensity, high efficiency, and high safety. Especially for complex workstations, such as robots on two-tiered skids, the entire process only requires one import / export of the skid to achieve quick tool changing, demonstrating strong potential for widespread application.
[0004] In step S2 of the above technical solution, a tool tray containing new robot tools and an empty tool tray are placed on the skid, and the two tool trays are fixedly connected to the skid. However, since the skid is located on the track and is higher than the ground, it is difficult to push the tool tray containing new robot tools directly onto the skid using rollers. It still needs to be manually moved to complete the above operation, which makes the replacement process more cumbersome.
[0005] Based on this, the present invention proposes a quick tool changing mechanism for robots. Utility Model Content
[0006] To address the aforementioned technical problems, this utility model proposes a quick tool changing mechanism for robots. This mechanism allows a tool tray to be directly pushed onto a sliding seat via rollers using an auxiliary plate, and then quickly secured by a limiting plate. This achieves rapid installation and fixation of the tool tray, improving the practicality of the device.
[0007] The technical solution to achieve the purpose of this utility model is: a robot tool quick change mechanism, including a slide rail, two sliding seats slidably connected on the slide rail, the two sliding seats being fixedly connected to each other, and further comprising;
[0008] The fixed frame is fixedly connected to two sliding seats. Two auxiliary plates are fixedly connected to the two sliding seats. Two sliding plates are slidably connected to the two fixed frames. Two limiting plates are fixedly connected to the two sliding plates. Multiple springs are fixedly connected to the two sliding plates. The multiple springs are fixedly connected to the sliding seats.
[0009] Preferably, each of the two sliding seats is provided with two tool trays, and each of the two tool trays is provided with four rollers.
[0010] Preferably, each of the two tool trays is provided with four support frames, and each of the four support frames is provided with four quick-release points.

[0013] Preferably, a plurality of springs are fixedly connected to the connecting plate, and the plurality of springs are fixedly connected to the limiting seat.
[0014] Compared with existing technologies, the significant advantages of this invention are:
[0015] Firstly, in this utility model, the fixed frame, auxiliary plate, tool tray and rollers work together. The auxiliary plate connects the ground and the top of the sliding seat, so that the tool tray can be pushed directly to the top of the sliding seat along the auxiliary plate. The sliding plate, limiting plate and spring work together to realize the quick installation and fixation of the tool tray, which improves the working efficiency of the device.
[0016] Secondly, in this utility model, the combination of the limiting seat, elastic protrusion, locking block, connecting plate and spring allows the sliding seat to be quickly clamped and fixed by the elastic protrusion and locking block when it moves to the tool changing station, thus preventing the sliding seat from shaking during the tool changing process.

[0024] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0025] This utility model provides an improved quick tool changing mechanism for robots. The technical solution of this utility model is as follows:
[0026] like Figures 1-4 As shown, a quick-change mechanism for robot tools includes a slide rail 1, on which two sliding seats 2 are slidably connected and fixedly connected. One sliding seat 2 is used to hold a new robot tool, and the other sliding seat 2 is used to hold an old robot tool. The mechanism also includes:
[0027] Two fixed frames 3 are fixedly connected to two sliding seats 2 respectively. The cross-section of the fixed frame 3 is U-shaped. Two auxiliary plates 4 are fixedly connected to the two sliding seats 2 respectively. The cross-section of the auxiliary plates 4 is right-angled triangle. The inclined surface of the auxiliary plates 4 connects the ground to the top of the sliding seats 2, so that the tool tray 8 can be pushed directly to the top of the sliding seats 2 along the auxiliary plates 4. Two sliding plates 5 are slidably connected to the two fixed frames 3 respectively. Two limiting plates 6 are fixedly connected to the two sliding plates 5 respectively. The cross-section of the limiting plates 6 is right-angled trapezoid. Multiple springs 7 are fixedly connected to the two sliding plates 5 respectively. The springs 7 are distributed in a linear array on the sliding plates 5. The multiple springs 7 are fixedly connected to the sliding seats 2. Through the cooperation of the sliding plates 5, the limiting plates 6 and the springs 7, the tool tray 8 can be quickly installed and fixed, which improves the working efficiency of the device.
[0028] Furthermore, such as Figures 1-4 As shown, each of the two sliding seats 2 is provided with a tool tray 8, and each of the two tool trays 8 is provided with four rollers 10. The rollers 10 make the tool trays 8 easy to move, thus improving the flexibility of the device.
[0029] Furthermore, such as Figures 1-4 As shown, each of the two tool trays 8 is provided with four support frames 9, and each of the four support frames 9 is provided with four quick-release points 11. The quick-release points 11 are used to support the robot tools and to keep the robot tools in the installation position.
[0030] Furthermore, such as Figures 1-4 As shown, a limiting seat 12 is fixedly connected to the slide rail 1. The cross-section of the limiting seat 12 is "H" shaped, and the limiting seat 12 is provided with an elastic protrusion 13.
[0031] Furthermore, such as Figures 1-4 As shown, a connecting plate 15 is slidably connected to the limiting seat 12, and a locking block 14 is fixedly connected to the connecting plate 15. The cross-section of the locking block 14 is a right trapezoid.
[0032] Furthermore, such as Figure 4 As shown, multiple springs 16 are fixedly connected to the connecting plate 15. The springs 16 are arranged in a linear array on the connecting plate 15. The multiple springs 16 are fixedly connected to the limiting seat 12. The sliding seat 2 is clamped and fixed by the elastic protrusion 13 and the locking block 14 to prevent the sliding seat 2 from shaking during tool changing.
[0033] The specific working method is as follows: The roller 10 can push the tool tray 8 to move. Since the cross-section of the auxiliary plate 4 is a right-angled triangle, its inclined surface connects the ground to the top of the sliding seat 2, allowing the tool tray 8 to be pushed directly above the sliding seat 2 along the auxiliary plate 4. As it moves, the tool tray 8 meets the limiting plate 6, first pushing the limiting plate 6 downwards and compressing the spring 7. When the end of the tool tray 8 away from the auxiliary plate 4 is in contact with the end of the fixed frame 3 near the sliding plate 5, the limiting plate 6 resets and moves upwards under the action of the spring 7, using the limiting plate 6 to lock the tool tray 8 in place within the fixed frame 3, thus completing the process. The tool tray 8 is quickly installed, and then the sliding seat 2 drives the tool tray 8 to move on the slide rail 1. When it moves to the tool changing station, the sliding seat 2 first squeezes the elastic protrusion 13 so that it is embedded in the limiting seat 12. As it moves, the sliding seat 2 meets the locking block 14. The sliding seat 2 no longer squeezes the elastic protrusion 13, and the elastic protrusion 13 is reset. At this time, the sliding seat 2 is located between the elastic protrusion 13 and the locking block 14, which fixes the sliding seat 2 and prevents the sliding seat 2 from shaking during the tool changing process. After the tool changing is completed, the connecting plate 15 is pressed so that the locking block 14 is embedded in the limiting seat 12, so that the sliding seat 2 can continue to move.
[0034] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
