Abstract

The utility model discloses a fetch-type straight-line tool magazine, which aims at providing the fetch-type straight-line tool magazine with simple structure, light motion, and convenient tool change. The tool magazine comprises a tool magazine shell, an interconnecting piece, a tool magazine gate, a guide part, a power unit, cutter heads, a cutter, etc. A lead rail and a cylinder rod are connected with a connecting plate through bolts, the tail end of the lead rail is connected with a cutter frame, and a plurality of cutter heads with same specification are arranged on the cutter frame. The tool magazine shell is connected with a machine tool body through the interconnecting piece, at the same time, one side of the shell connects the tool magazine gate with the shell through a pair of hinges, and the front part of the tool magazine gate uses the hinges to lead the tool magazine gate, a connecting rod, a connecting rod support to be connected with the tool magazine respectively. In addition, the tool magazine also comprises a sensor and a corresponding closed loop circuit, so as to help the tool magazine realize the order performance of the actions of pushing out and closing the tool magazine as well as changing the cutter, etc., and ensure the accuracy of the system action and the reliability of the system.

Description

A kind of directly taking type row formula tool magazine

Technical field:

The utility model relates to a kind of tool magazine, particularly relates to a kind of directly taking type row formula tool magazine that is applicable to middle-size and small-size planer type numerical control engraving machine.

Background technology:

Middle-size and small-size planer type numerical control engraving machine is the lathe that is mainly used in precision die, specialty products processing, on this lathe tool magazine is installed, and utilizes the relative engagement action of main shaft and tool magazine, can reach main shaft and take off the purpose that cutter carries out machining from the tool magazine place.Existing tool magazine, as: umbrella shape, disc type, umbrella formula etc., volume is all bigger, and price is also all than higher, and is compact for the space, and middle-size and small-size numerical control digital-controlled carving machine on the low side is not suitable for very much.

Summary of the invention:

Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, provides a kind of directly taking type simple in structure, that motion is light to arrange the formula tool magazine.

The technical solution of the utility model is summarized as follows:

A kind of directly taking type row formula tool magazine is characterized in that being made up of tool magazine shell 1, attaching parts 2, tool magazine door 3, guiding parts 4, power part 5, cutterhead 6, cutter 7 etc.Guide rail links to each other with gusset piece by screw with cylinder rod, and the end of guide rail links to each other with knife rest, and the cutterhead of several same specifications is installed on the knife rest.Connect by attaching parts 2 between the shell of tool magazine and the machine body, simultaneously, a side of shell links to each other shell by a pair of hinge with the tool magazine door, and the place ahead of tool magazine door then links up tool magazine door, connecting rod, connecting rod rack and cutterhead with hinge respectively.

Sensor in the directly taking type row formula tool magazine and corresponding closed loop circuit can help the order execution of actions such as it is released, closes, tool changing, have guaranteed the accuracy of system acting and the stability of system.

Compared with prior art, the beneficial effects of the utility model are: 1) simple in structure, the motion light; 2) floor space is little, and tool changing is convenient; 3) can in less space, both realize the tool changing function having guaranteed bigger machining area again.

Description of drawings:

Fig. 1 is the signal that the utility model tool magazine is released state;

Fig. 2 is the schematic diagram that the utility model tool magazine retracts state;

Fig. 3 is the control flow chart of the utility model action.

Wherein, 1 is that tool magazine shell, 2 is that attaching parts, 3 are that tool magazine door, 4 is that guiding parts, 5 is that power part, 6 is that cutterhead, 7 is a cutter.

The specific embodiment:

As shown in Figure 1, the utility model comprises parts such as tool magazine shell 1, attaching parts 2, tool magazine door 3, guiding parts 4, power part 5, cutterhead 6.Wherein, shell 1 mainly plays a protective role; Attaching parts 2 are mainly used in and connect lathe and tool magazine; Tool magazine door 3 is used for the protection to cutterhead and cutter, and protection cutterhead and cutter are not subjected to the influence of smear metal etc. when machine tooling; Guiding when guiding parts 4 is mainly used in the cutterhead release and retracts; Power part 5 is made up of cylinder, cylinder rod and auxiliary air passage thereof, the release of being responsible for cutterhead with retract.

Like this, the power of this tool magazine is by cylinder and auxiliary air passage input thereof, and cutterhead along with guiding rail is released, is made horizontal straight line and moved under the driving of cylinder power.Because cutterhead and connecting rod connect by connecting rod rack, and between connecting rod and the tool magazine door by hinge-coupled, so when knife rest is released, connecting rod rack spurs connecting rod and moves, and then haul the tool magazine door and outwards open (as shown in Figure 1); When knife rest retracted, connecting rod rack was pushing away connecting rod and is moving, and then was pushing away the tool magazine door and oppositely close (as shown in Figure 2).

When needing tool changing in the process, control system is sent tool changing instruction, and tool magazine of the present utility model system then finishes following action (as shown in Figure 3) successively:

1) send tool changing instruction when the system of receiving of tool magazine system, at first carry out the cutter inspection, mainly check current cutter physical state whether with the system logic state consistency.If inconsistent, mistake will be pointed out by system;

2) if cutter is checked safety, system will open the tool magazine door, release cutterhead;

3) analyze the tool changing action, if work as forward spindle cutter is arranged, system will have cutter to put back to affiliated cutter spacing on main shaft earlier, and then the gripping finger number of delimiting the organizational structure cutter; Do not have cutter if work as forward spindle, system is with the earlier direct gripping finger number of delimiting the organizational structure cutter;

4) cutterhead retracts, and closes the tool magazine door; Log off then.

Each step action of above-mentioned tool magazine system all realizes closed loop by sensor and circuit, can accurately monitor the situation of finishing of action, thereby improve the stability of system.
