Description

Numerically controlled lathe

Technical field

The utility model relates to a kind of pipe fitting process equipment field, and more particularly, it relates to a kind of numerically controlled lathe.

Background technology

Numerically controlled lathe is plant equipment more common in machining equipment, therefore applies also more extensive.Numerically controlled lathe is generally all be provided with knife rest, knife rest can realize rotating relative to fuselage, and knife rest is squaring head, lathe tool can be installed in four limits of knife rest, then be bolted, different processing can be carried out to workpiece after squaring head being installed different lathe tools, in process, also can switch lathe tool, make the processing of workpiece can meet the demand of product.

For existing numerically controlled lathe in process, because mechanical oscillation are larger, and carry out in the process of rotating at knife rest, knife rest departs from spacing base by the effect of cylinder, then rotate, drop after rotating 90 ° the spacing base of meeting, thus can switch cutter, but, the existence of mechanical oscillation can have influence on the levels of precision of knife rest in the process switching cutter, and due to in pipe fitting process, the lathe tool of numerically controlled lathe carries out pipe fitting making pipe fitting produce metal fragment in the course of work of a turning, metal fragment also can be wound on knife rest, there is impact in the Process Precision that the knife rest being is switching cutter, the stability of knife rest also can affect, thus the probability of substandard products can be improved.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of knife rest accurate positioning, and the numerically controlled lathe that stability is high.

For achieving the above object, the utility model provides following technical scheme: a kind of numerically controlled lathe, comprise fuselage and knife rest, described knife rest comprises base and tool fixing seat, described tool fixing seat is rotatably connected with base by rotating shaft, the bottom of described tool fixing seat is provided with four stopper slots, four described stopper slots are that circumference is uniformly distributed in the center of tool fixing seat, described base is provided with the limited block cooperatively interacted with stopper slot size, wherein, limited block stretches in stopper slot and tool fixing seat is in Working position, the sidewall of described limited block is coated with buffer layer.

Preferably, described stopper slot internal fixtion has magnet, and described limited block is magnetic material, and described limited block is wound with coil, and described coil is connected with control circuit, and described control circuit control coil leads to forward current and adhesive magnet or same logical negater circuit repel magnet.

Detailed description of the invention

Referring to figs. 1 through Fig. 5, the utility model numerically controlled lathe embodiment is described further.

As shown in Figure 1, a kind of numerically controlled lathe, comprise fuselage 1 and knife rest 2, described knife rest 2 comprises base 21 and tool fixing seat 22, described tool fixing seat 22 is rotatably connected with base 21 by rotating shaft, knife rest 2 of the prior art is by the rotation of rotating shaft realization at base 21, but knife rest 2 of the prior art is in the process switching cutter, by the rotation of rotating shaft, tool fixing seat 22 is rotated, thus be switched to different cutters, make it possible to process workpiece with different cutters, its principle is repeated no more for knife rest 2 of the prior art, this programme is on the basis of existing technology, by arranging four stopper slots 3 in the bottom of tool fixing seat 22, stopper slot 3 can be circular or rectangle, circular stopper slot 3 is employed in the present embodiment, bottom surface due to tool fixing seat 22 is foursquare, four described stopper slots 3 are that circumference is uniformly distributed in the center of tool fixing seat 22, and stopper slot 3 is undertaken spacing by limited block 4, the position of restriction is the position of tool sharpening, like this, cutter is once switch, will process, and due to the matching relationship between limited location block 4 and stopper slot 3 in process, the stability of cutter in process is improved, described base 21 is provided with the limited block 4 cooperatively interacted with stopper slot 3 size, wherein, limited block 4 stretches in stopper slot 3 and tool fixing seat 22 is in Working position, so just serve spacing effect, make knife rest 2 can ensure more accurately to be in Working position everywhere when switching cutter, and skew is less likely to occur.The sidewall of described limited block 4 is coated with buffer layer 5, can reduces the mechanical oscillation of knife rest 2, thus make knife rest 2 more stable, tool sharpening product out meets standard, reduction in the numbers of seconds more, thus cuts the waste, and saves enterprise's production cost.

Chip can be carried out to workpiece in process for cutter, thus produce more iron filings, and iron filings can affect knife rest 2 switches cutter, base 21 is provided with garbage collection pipe 8, garbage collection pipe 8 is flexible pipe, can free bend, the position that opening produces towards waste material, described garbage collection pipe 8 is connected with Negative pressure machine 9, Negative pressure machine 9 produces negative pressure, thus air-flow is formed in garbage collection pipe 8, waste material iron filings freely can be entered from garbage collection pipe 8, and Negative pressure machine 9 is produced negative pressure and is removed by waste material by collecting pipe.Further, Negative pressure machine 9 is also connected with the collecting box 10 for storing waste material.Have a lot of waste recovery in collecting box 10 to come in, and it is stored, and can utilize by secondary, cost-saving, cut the waste.

As shown in Figure 2, the size of stopper slot 3 and limited block 4 adapts, and tool fixing seat 22 will be made when limited block 4 extend in stopper slot 3 to fix, and prevents tool fixing seat 22 from offseting.

As shown in Figure 3, stopper slot 3 internal fixtion has magnet 6, magnet 6 is that the mode bonded by glue is fixed on stopper slot 3 inside, described limited block 4 is magnetic material, as shown in Figure 4, described limited block 4 is wound with coil 7, and described coil 7 is connected with control circuit A, and described control circuit A control coil 7 leads to forward current and adhesive magnet 6 or same logical negater circuit repel magnet 6.Control circuit A comprises the first K switch 1, second switch K2, forward power supply S1 and reverse electrical source S2, described forward power supply S1 connects after the first K switch 1 and is parallel on coil 7, be parallel on coil 7 after described reverse electrical source S2 series connection second switch K2, described coil 7 is also in series with current-limiting resistance.First K switch 1 and second switch K2 can Non-follow control, when the first K switch 1 closes, coil 7 will be made to lead to forward current thus limited block 4 is magnetized, thus generation magnetic force, limited block 4 can be made to be pull-in in stopper slot 3 fast by the interaction of magnetic force, thus improve spacing stability, and disconnect the first K switch 1, closed second switch K2, the magnetic force that magnetic is contrary will be produced, thus can produce magnet 6 opposite effect power, make limited block 4 can remove spacing effect.

Owing to can, by simultaneously closed situation, control circuit A can be made unstable, therefore when the first K switch 1 and second switch K2 control, first K switch 1 is contrary with the state of second switch K2 and formed and link, what adopt is interlock switch, wherein, only has a switch to remain closed under the same time.As shown in Figure 5, the first K switch 1 and second switch K2 form the contrary interlock switch K of state, thus can avoid situation about simultaneously closing, and make circuit more stable, control convenient.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
