[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0023] like Figure 1-6 As shown, a tool magazine linkage mechanism for a CNC engraving machine includes a machine base 1, a gantry frame 2 connected to the machine base 1, a Y-axis co-track conveying module 3 connected to the machine base 1 and passing through the gantry frame 2, a tool magazine body 4 connected to the first output end of the Y-axis co-track conveying module 3, a worktable 5 connected to the second output end of the Y-axis co-track conveying module 3, a dustproof connecting cover 6 connected to the back of the crossbeam of the gantry frame 2, a protective door 7 hinged to the front end of the dustproof connecting cover 6, and a linkage assembly 8 connecting the protective door 7 and the tool magazine body 4. The first output end of the Y-axis co-track conveying module 3 is used to drive the tool magazine body 4 to move along the Y-axis direction, and the second output end of the Y-axis co-track conveying module 3 is used to drive the worktable 5 to move along the Y-axis direction. The protective door 7 is linked with the tool magazine body 4 through the linkage assembly 8.
[0024] In actual use, when the Y-axis co-rail conveying module 3 drives the tool magazine body 4 to move forward along the Y-axis, the tool magazine body 4 gradually moves forward and upward through the linkage, causing the protective door 7 to gradually flip forward and upward to form a channel, allowing the tool magazine body 4 to move forward to the front of the gantry 2; when the Y-axis co-rail conveying module 3 drives the tool magazine body 4 to move backward along the Y-axis, the tool magazine body 4 gradually moves downward and downward through the linkage assembly 8 until it closes, blocking the cutting fluid and chips outside the protective door 7 and the dustproof connecting cover 6, thus protecting the tool magazine body 4 from interference by cutting fluid and chips.
[0025] Furthermore, the protective door 7 has a connecting arm 9 extending from its side wall. The linkage assembly 8 includes a first connecting rod 81 and a connecting rod 82 fixedly connected to the side wall of the tool magazine body 4. The two ends of the first connecting rod 81 are respectively hinged to the front end of the connecting arm 9 and the middle of the connecting rod 82. The protective door 7 is linked with the tool magazine body 4 through the cooperation of the first connecting rod 81 and the connecting rod 82.
[0026] Furthermore, the end of the connecting rod 82 away from the tool magazine body 4 is bent upward to form a bent portion 10. A limiting guide post 11 for limiting the backward tilting angle of the first connecting rod 81 is inserted into the side of the bent portion 10 to prevent the first connecting rod 81 from tilting backward excessively during the backward movement of the tool magazine body 4, which would cause the protective door 7 to tilt downward and close prematurely, thus preventing a malfunction. It also prevents the tool magazine body 4 from remaining outside the protective door 7 after the protective door 7 is closed.
[0027] Furthermore, a hinge 12 connects the front end face of the dustproof connecting cover 6 and the dustproof surface of the protective door 7. The dustproof connecting cover 6 and the protective door 7 are hinged together by the hinge 12.
[0028] Furthermore, the front end of the back of the protective door 7 is recessed to form a clearance space 13 for avoiding the tool magazine body 4, which helps to prevent the protective door 7 from colliding with the tool magazine body 4 or the tool handle on it during the linkage process.
[0029] Furthermore, the Y-axis co-rail conveying module 3 includes a Y-axis double slide rail 31 connected to the machine base 1 and passing through the gantry 2, a first slider group 32 slidably engaged with the Y-axis double slide rail 31, a second slider group 33 slidably engaged with the Y-axis double slide rail 31, a first lead screw motor 34 fixedly connected to the machine base 1 and arranged parallel to the Y-axis double slide rail 31, a first lead screw nut 35 threadedly connected to the first lead screw motor 34, a second lead screw motor 36 connected to the machine base 1 and arranged parallel to the Y-axis double slide rail 31, and a second lead screw nut 37 threadedly connected to the second lead screw motor 36. The tool magazine body 4 and the worktable 5 are slidably connected to the Y-axis double slide rail 31 through the first slider group 32 and the second slider group 33, respectively. The first lead screw nut 35 is fixedly connected to the bottom of the tool magazine body 4, and the second lead screw nut 37 is fixedly connected to the bottom of the worktable 5. The rotation of the lead screw end of the first lead screw motor 34 drives the first lead screw nut 35 and the tool magazine body 4 to move along the double slide rail 31 along the Y-axis. The rotation of the lead screw end of the second lead screw motor 36 drives the second lead screw nut 37 and the worktable 5 to move along the double slide rail 31 along the Y-axis. The tool magazine body 4 and the worktable 5 share the double slide rail 31 along the Y-axis, which makes more effective use of the space of the machine tool 1 and improves the space utilization rate.
[0030] Furthermore, the Y-axis co-rail conveying module 3 also includes two baffles 38 respectively mounted on both ends of the Y-axis double slide rail 31, and a dust cover 39 connected to the top of the two baffles 38, which helps to prevent cutting fluid and chips from falling into the Y-axis co-rail conveying module 3.
[0031] Furthermore, the tool magazine body 4 includes a first carriage plate 41, two first support plates 42 fixedly connected to both sides of the first carriage plate 41, a straight-line tool magazine base plate 43 connected to the top of the two first support plates 42, and a reinforcing plate 44 connecting the straight-line tool magazine base plate 43 and the two first support plates 42. The first lead screw nut 35 and the first slider group 32 are both fixedly connected to the bottom of the first carriage plate 41. There is a first space 14 between the reinforcing plate 44 and the first carriage plate 41 for the dust cover 39 to pass through. While ensuring that the dust cover 39 plays a dustproof role, it also avoids the tool magazine body 4 from being affected by the dust cover 39 during movement, so that the tool magazine body 4 can move smoothly.
[0032] Furthermore, the workbench 5 includes a second carriage plate 51, two second support plates 52 fixedly connected to both sides of the second carriage plate 51, and a carrier mounting platform 53 connected to the top of the two second support plates 52. The second lead screw nut 37 and the second slider group 33 are both fixedly connected to the bottom of the second carriage plate 51. There is a second space 15 between the carrier mounting platform 53 and the second carriage plate 51 for the dust cover 39 to pass through. While ensuring that the dust cover 39 plays a dustproof role, it avoids the workbench 5 from being affected by the dust cover 39 during movement, so that the workbench 5 can move smoothly.
[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
