Description

A kind of Installing machine tool cutter arrangement

Technical field

The utility model relates to mechanical grip field of tool, particularly relates to a kind of Installing machine tool cutter arrangement.

Background technology

Along with the development of machinery industry, numerically controlled lathe from now on will to medium-to-high grade development, dress cutter and tool setting are extremely important and complicated groundworks during lathe in machining operates, the precision of dress cutter and tool setting is by the dimensional accuracy of the establishment and part that directly affect procedure, the knife rest of numerically controlled lathe is the important component part of lathe, knife rest is for clamping the cutter cut, and therefore its structure directly affects cutting ability and the stock-removing efficiency of lathe.To a certain extent, the stuctures and properties of knife rest embodies the design and fabrication technology level of lathe.Along with the development of numerically controlled lathe, cutter frame structure form is also constantly updating.Wherein by the difference of tool changing mode, the tool holder system of numerically controlled lathe mainly contains the various ways such as the automatic tool changer of circular cutter holder, row's formula knife rest and band tool magazine.

There is many weak points in current mounting cutter device, as traditional lathe saddle filled a cutter, the speed of tool changing is slow, also must tool setting again after tool changing, and precision is not high, and production efficiency is low, the needs of modern production can not be adapted to, on the other hand, during Installing machine tool cutter arrangement mounting cutter, often occur that cutter positioning is inaccurate, fix the shortcomings such as insecure.

In view of above-mentioned defect, the utility model creator obtains this creation finally through long research and practice.

Summary of the invention

The purpose of this utility model is to provide a kind of Installing machine tool cutter arrangement, there is transposition fast, positioning precision is high, tangential moment of torsion is large, effectively can raise labour productivity, shorten the Operational preparation time, eliminate human error, improve the advantages such as the uniformity of machining accuracy and machining accuracy, solve Problems existing in background technology.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Installing machine tool cutter arrangement, comprises rotating shaft, and described rotating shaft arranged outside circle overlaps and circle cover outside hold-down nut screw mandrel; Described circle cover top arranges magnetic sheet, and circle cover is connected with the handle being arranged on rotating shaft top; Described circle cover side arranges cutter draw-in groove and lathe tool is installed in cutter draw-in groove inside; Described cutter draw-in groove top suit trip bolt; Arrange bottom described cutter draw-in groove instead by dish and be instead connected with a joggle by dish and fluted disc; Described fluted disc bottom is arranged worm and worm gear and is connected by gear between fluted disc with worm and worm gear; Described worm and worm gear is instead connected by the drive link coiling side with being arranged on.

Further, described handle is a kind of handle of L shape structure, and handle is fixedly connected with circle cover.

Further, described circle cover, rotating shaft run through magnetic sheet inside.

Further, the magnetic sheet of described magnetic sheet to be a kind of cross section be rectangular configuration.

Further, can to move between described trip bolt and cutter draw-in groove and cutter draw-in groove is multiple draw-in groove.The beneficial effects of the utility model are:

1, compact conformation, service life is of a specified duration;

2, the transposition of this kind of mounting cutter device is fast, and positioning precision is high, and tangential moment of torsion is large, can effectively raise labour productivity, and shortens the Operational preparation time, eliminates human error, improves the uniformity of machining accuracy and machining accuracy;

3, the ability to work of processing technology adaptability and continous-stable also significantly improves, especially when the part that processing geometry is more complicated, facilitate the various cutters needed for clamped one time, complete the processing of various geometry flexibly and easily, there are good economic benefit and social benefit, are applicable to promoting the use of.

Fig. 2 is the utility model overall structure schematic diagram.

Detailed description of the invention

Below in conjunction with accompanying drawing, to above-mentioned being described in more detail with other technical characteristic and advantage of the utility model.

Refer to shown in Fig. 1 and Fig. 2, a kind of Installing machine tool cutter arrangement, comprises rotating shaft 1, and described rotating shaft 1 arranged outside is justified cover 2 and justified hold-down nut screw mandrel 3 outside cover 2; Described round cover 2 top arranges magnetic sheet 8, and circle cover 2 is connected with the handle 6 being arranged on rotating shaft 1 top; Described round cover 2 side arranges cutter draw-in groove 9 and lathe tool 12 is installed in cutter draw-in groove 9 inside; Described cutter draw-in groove 9 top suit trip bolt 7; Arrange bottom described cutter draw-in groove 9 instead by dish 10 and be instead connected with a joggle by dish 10 and fluted disc 4; Described fluted disc 4 bottom is arranged worm and worm gear 5 and is connected by gear between fluted disc 4 with worm and worm gear 5; Described worm and worm gear 5 be arranged on the anti-drive link 11 by dish 10 side and be connected.

As optimisation technique scheme of the present utility model: described handle 6 is a kind of handle 6 of L shape structure, and handle 6 is fixedly connected with circle cover 2; It is inner that described round cover 2, rotating shaft 1 run through magnetic sheet 8; The magnetic sheet 8 of described magnetic sheet 8 to be a kind of cross section be rectangular configuration; Can to move between described trip bolt 7 and cutter draw-in groove 9 and cutter draw-in groove 9 is multiple draw-in groove.

In use of the present utility model, after digital control system sends tool changing instruction, by interface circuit, motor is rotated forward, through transmission device 11, drive worm and worm gear 5, worm gear drives leading screw and nut mechanism 3 to be rotated counterclockwise, now because fluted disc 4 is in engagement, when leading screw and nut mechanism 3 rotates, fluted disc unclamps and lifts by the axial force that upper slitter support body is produced upwards, until two location fluted discs 4 depart from engagement, thus drive upper tool post and fluted disc to produce action of appearing on the stage, when circle cover 2 turns over 150 ° counterclockwise, fluted disc 4 is thrown off completely, now pin accurately enters in the groove in round cover 2, drive tool-post structure transposition, when upper tool post forwards to after needs put in place, the tool changing instruction that numerical control device sends makes the some gatings in Hall switch, after magnetic sheet 8 aligns with the Hall switch be strobed, Hall switch feedback signal makes motor reversal, latch enters anti-leaning in dish 10 geosyncline under spring force and carries out coarse positioning, upper slitter support body stops operating, motor continues reversion, it is made to fall in this position, make upper tool post move on to fluted disc 4 by nut-screw rod mechanism 3 again to engage, realize accurately location, after knife rest is accurately located, motor allows reversion, clamping knife rest, when two fluted discs are increased to certain clamping force, motor stops reversion by numerical control device, prevent motor from not stopping to reverse and overload breaking-up, thus complete an exchanging knives process.

The foregoing is only preferred embodiment of the present utility model, is only illustrative for utility model, and nonrestrictive.Those skilled in the art is understood, and requires to carry out many changes to it in the spirit and scope that limit, amendment in utility model right, even equivalent, but all will fall in protection domain of the present utility model.
