Abstract
The utility model discloses a machining center auxiliary tool changer which comprises a tool rest, a flat plate, a linear guide rail and an elastic limiting device. The tool rest is fixed on the flat plate and used for placing of tools. The flat plate is arranged on the linear guide rail in sliding mode, and the sliding direction of the flat plate is the same as the axial direction of the tools arranged on the tool rest. One end of the flat plate, far away from handles of the tools, is provided with the elastic limiting device which is used to restrict the sliding distance of the flat plate on the linear guide rail, and the sliding distance is larger than or equal to the axial displacement of the tools at the time that a main shaft of a machining center clamps the tools. The machining center auxiliary tool changer achieves automatic replacement of tools which are beyond working limit of a normal tool changer, and fully achieves machining automation.

Technical field
The utility model relates to machining center, specifically, relates to be used to the secondary tool magazine of machining center of depositing the large cutter that surpasses operator storehouse working limit.
Background technology
Briefly, machining center is exactly the integrated of CNC milling machine and tool magazine.CNC milling machine does not have tool magazine, in the process, whenever uses one cutter, and then next cutter that will manually change the outfit could continue processing, and this has increased a lot of non-process times, and operating efficiency is lower, for the client, has namely increased cost per unit.Be to reduce cost, machining center arises at the historic moment, and the cutter of this equipment is placed in the tool magazine, and one used cutter and namely automatically changes a cutter, had so just saved tool change time than manual tool changing, had reduced the time beat, had improved operating efficiency.
In actual the use, our range of work that can run into lathe satisfies the processing request of workpiece sometimes, but the weight of some cutter, moment of torsion, diameter are too large, can't be put in the tool magazine, thereby can not realize the situation of automatic tool changer.For this reason, the larger lathe of some user selection buying, the automatic tool changer that exceeds the cutter of little machine cutter holder working limit to satisfy these; Some client cutter of then selecting to transfinite is placed on outside the lathe, when using these cutters, and manual tool changing again.More than these measures be not the best approach of dealing with problems, such as the larger lathe of buying input cost is strengthened, and sometimes can't satisfy equally the automatic tool changer of some cutters that transfinite; Manual tool changing has then increased the time beat, has reduced operating efficiency, has also increased the weight of operating personnel's work load simultaneously, has increased the probability of makeing mistakes.
The utility model content
The purpose of this utility model is to provide a kind of machining center secondary tool magazine, exceeds the automatic tool changer problem of the cutter of common tool magazine working limit with solution, fully realizes process automation.
For reaching this purpose, the utility model by the following technical solutions:
The secondary tool magazine of a kind of machining center, comprise knife rest, flat board, line slideway and elastic limit device, described knife rest is fixed on the flat board, be used for arrangement of tool, described flat board is slidingly arranged on the described line slideway, its glide direction be placed on knife rest on cutter axially identical, and its end away from the cutter handle of a knife is provided with elastic limit device, described elastic limit device is used for limiting the sliding distance of described flat board on described line slideway, and described sliding distance is more than or equal to the axial movement value of machining center main shaft cutter when the clamp-on tool.
Preferably, described elastic limit device comprises bearing, bearing pin, spring and plug screw, offer ladder hole on the described bearing, there is the step of a projection at the middle part of described bearing pin, the diameter of described step is greater than the path of ladder hole, large footpath less than ladder hole, described bearing pin is located in the ladder hole of described bearing, and the one end stretches out the miner diameter end of ladder hole on the described bearing, and be fixedly connected with described flat board, its other end overlaps a spring, and described plug screw is with the bigger diameter end shutoff of ladder hole on the described bearing.
Preferably, described knife rest comprises two V-blocks and a support nail, and wherein the first V-block snaps in the dovetail groove of cutter shank portion, and another V-block is stuck in the middle part of cutter, and support nail is supported on the cutterhead part of cutter.
Preferably, the thickness of described the first V-block deducts the difference of described cutter axial movement value less than or equal to described dovetail groove bottom width.
Operation principle of the present utility model is: by providing a kind of specially designed secondary tool magazine for existing machining center, the cutter that will exceed common tool magazine working limit is placed on the secondary tool magazine, then utilize main axle moving method of corresponding cutters position to the secondary tool magazine to realize crawl and the release of cutter, thereby reach automatic tool changer, fully realize the purpose of process automation.
The beneficial effects of the utility model are: make machining center realize automatic tool changer to the cutter that exceeds common tool magazine working limit, fully realized process automation.
Description of drawings
Fig. 1 is the structural representation of the secondary tool magazine of machining center of the utility model embodiment;
Among the figure: 1, flat board; 2, line slideway; 3, cutter; 4, bearing; 5, bearing pin; 6, spring; 7, plug screw; 8, support nail; 9, the first V-block.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the utility model in detail.
As shown in Figure 1, the secondary tool magazine of the machining center of the utility model embodiment, comprise knife rest, dull and stereotyped 1, line slideway 2 and elastic limit device, described knife rest is fixed on dull and stereotyped 1, be used for arrangement of tool 3, described dull and stereotyped 1 is slidingly arranged on the described line slideway 2, its glide direction be placed on knife rest on cutter 3 axially identical, and its end away from cutter 3 handle of a knifes is provided with elastic limit device, described elastic limit device is used for limiting described dull and stereotyped 1 sliding distance on described line slideway 2, and described sliding distance is more than or equal to the axial movement value of machining center main shaft cutter 3 when the clamp-on tool 3.
By the manual tool changing experience as can be known, when machining center main shaft claming cutter, cutter can be pulled in the main shaft and go, and namely cutter has a shifting amount in the axial direction; When machining center main shaft loosening cutter, cutter can eject from main shaft, also is that cutter has a shifting amount in the axial direction equally.
Because the machining center main shaft is when loosening cutter, the size of cutter axial movement value is applied to the impact of the resistance on the cutter, and the shifting amount when minimum shifting amount should be cutter by main shaft claming, so for ease of recording an accurately shifting amount a reference value, when the measurement of cutter axial movement value is selected in cutter by main shaft claming.
The axial movement value of cutter can by cutter before by main shaft claming critical localisation and clamp after the variation of ultimate position draw, as drawing with respect to the variation of the distance of spindle flange by measuring cutter handle of a knife back flange.
