The specific embodiment
Describe below in conjunction with the technical scheme of accompanying drawing utility model.
Embodiment one, as shown in Figures 1 to 4, a kind of straight-line tool magazine device of numerical controlled engraving and milling device, comprise tool magazine plate 2, be arranged at tool magazine support 1, the cylinder 7 of tool magazine plate 2 belows, cylinder 7 is fixedlyed connected with tool magazine support 1, and described tool magazine plate 2 is provided with cylinder contiguous block 5, and the cylinder axis 71 of cylinder 7 passes tool magazine support 1 and is connected with described cylinder contiguous block 5.Described tool magazine plate 2 belows are provided with guide rail 3, and tool magazine support 1 is provided with guide rail slide block 4, and described guide rail slide block 4 slides on described guide rail 3, thereby realize that tool magazine plate 2 and tool magazine support 1 rail connect.Used the tool magazine device of said structure, simple in structure, easy to operate.During work, tool magazine support 1 is fixed on carving and mills on the lathe crossbeam of machine, and cylinder 7 is as motive force, promote tool magazine plate 2 and move to assigned address by guide rail slide block 4 forward or backward along guide rail 3, thereby moves the position of realizing tool magazine plate 2 exchanging knives processes.
In the present embodiment, as preferred implementation, the straight-line tool magazine device of a kind of numerical controlled engraving and milling device described in the utility model, also comprise the stopping means 9 that is arranged at tool magazine plate 2 belows, described stopping means 9 includes limiting bracket 93 and is arranged at stop 91 and beam 92 on the described limiting bracket 93, and limiting bracket 93 is connected with tool magazine plate 2 by limited screw 931; Described stop 91 is the mechanical type stop, and this stop 91 has scalable structure, and described stop 91 1 ends are provided with first collision block 911.During work, cylinder 7 drives tool magazine plate 2 and moves forward along guide rail 3, stop 91 moves forward with tool magazine plate 2 and close gradually tool magazine support 1, strike the assigned address of tool magazine support 1 then when first collision block 911 of stop 91, digital control system receives information, promptly send instruction, tool magazine plate 2 stops to move, beginning tool changing work; After tool changing finished, cylinder 7 drive tool magazine plates 2 slide backward got back to original position.So, just can realize the accurate location of tool magazine at exchanging knives process, tool change time is fast, has effectively guaranteed the tool changing quality.Described stop 91 has scalability, plays the effect of buffer protection when bump tool magazine support 1.
In the present embodiment, described beam 92 1 ends are provided with second collision block 921, and the length of described beam 92 is shorter than the length of described stop 91.Collide the assigned address of tool magazine support 1 when stop 91; and digital control system is can't receive signal the time; cylinder 7 drives tool magazine plate 2 and continues reach; after second collision block 921 of beam 92 front ends strikes tool magazine support 1 relevant position; promptly stop tool magazine plate 2 to continue reach; thereby play a protective role, prevent stop 91 locate failures and cause tool magazine plate 2 to continue the damaged in collision that reach causes equipment.
Further, in the present embodiment, as preferred implementation, the straight-line tool magazine device of a kind of numerical controlled engraving and milling device described in the utility model, as Fig. 3, shown in Figure 5, also comprise the fixture of the spring 8 that is arranged at tool magazine plate 2, be used for tool magazine at the exchanging knives process clamp-on tool.Described fixture of the spring 8 comprises spring 81 and trim ring 82; described trim ring 82 is fixedly connected on tool magazine plate 2 with described spring 81; described spring 81 numbers are two at least; adopt this structure; it is many cutter that tool magazine can be changed simultaneously; increase work efficiency, its elasticity also helps the protection of cutter and clamping accuracy.
The operation principle of the straight-line tool magazine device of a kind of numerical controlled engraving and milling device described in the utility model is: during work, cutter drives at main shaft and is moved to preassigned position, waits for that tool magazine moves to the cutter position; Then, cylinder 7 drive tool magazine plates 2 along guide rail 3 to front slide, and position by stop 91, stop to move when assigned address is the cutter appointed positions when stop 91 moves to; Then, fixture of the spring 8 begins to draw sword-the slotting tool action, finishes cutter changing; At last, after exchanging knives process finished, cylinder 7 drive tool magazine plates 2 slided backward and return to original position.
Embodiment two as shown in Figures 1 to 4, present embodiment two is that with the difference of embodiment one described stop 91 is the photo-electric stop.Described stop 91 1 ends are provided with the inductor of transmitting-receiving photosignal, can send the information of position and the information of reception specified command to machine tool numerical control system.During work, stop 91 is through the pre-set assigned address of machine tool numerical control system, and cylinder 7 drives tool magazine plate 2 and moves forward along guide rail 3, when stop 91 moves forward to assigned address, promptly receive the signal that stops to move, cylinder 7 no longer promotes tool magazine plate 2 and moves, beginning tool changing work.After tool changing finished, cylinder 7 drive tool magazine plates 2 slide backward got back to original position, can realize the accurate location of tool magazine at exchanging knives process equally, and tool change time is fast, has effectively guaranteed the tool changing quality.
Above embodiment is only in order to the explanation the technical solution of the utility model but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
