Abstract

The utility model discloses a bamboo hat type tool magazine with an anti-collision device, which belongs to the technical field of machining and is mainly applied to a numerical control machine tool. The bamboo hat type tool magazine comprises a tool magazine body, a movable cabin door, a tool pan and a tool shank, wherein the movable cabin door is arranged on the tool magazine body; and the tool pan and the tool handle are arranged in the tool magazine. The bamboo hat type tool magazine is characterized in that: the movable cabin door is provided with a detection switch used after appropriate tool selection of the tool magazine and a data signal wire connected with the detection switch; and the data signal wire is connected to a control system host of the machine tool. Due to the adoption of the bamboo hat type tool magazine, the defect of frequent tool collision phenomenon occurring in a tool magazine of the conventional numerical control machining center is overcome, personal hurt possibly caused in production are avoided, and performance of machining production in an efficient and safe environment can be ensured.

Description

A kind of umbrella shape tool magazine with anticollision device, collision-prevention device

Technical field:

The utility model relates to a kind of umbrella shape tool magazine with anticollision device, collision-prevention device, and it belongs to the Machining Technology field, mainly is the tool magazine that is used for Digit Control Machine Tool.

Background technology:

Tool magazine is widely used on the machining center of numerical controlled machinery manufacture field, owing to aspect reasons such as electric, personnel operation, machineries, the random cutter phenomenon when calculating is inconsistent in actual cutter spacing of tool magazine and the system can occur.Be example with the umbrella shape tool magazine, as shown in fig. 1: because umbrella shape tool magazine tool changing mode be fixedly tool changing, tool magazine is behind random cutter, and when execution was gone back cutter and moved, the cutter that tool magazine reality is chosen number can require not to be inconsistent with system command.If on the actual cutter of choosing number handle of a knife is housed, cutter can appear hitting when the handle of a knife on the cutterhead in the tool magazine 11 33 moves on to main shaft 44 sides, and cause cutterhead claw, cutterhead, cutter etc. to break., 22 among Fig. 1 is movable door of the prior art.Secondly, when carrying out the tool magazine debugging, handle of a knife is not housed, when tool magazine moves on to the main shaft side, can occurs hitting cutter yet because operating personnel's negligence realizes on the cutter of main shaft number.Tool magazine hit the normal use that cutter has influenced lathe, even the personnel that cause injure, and have a strong impact on ordinary production and personal safety.From Fig. 1, also can find out behind the random cutter of tool magazine improper when going back cutter, tool magazine can hit phenomenon from cutter to the main shaft side shifting, promptly distortion because of having taken place with main shaft 44 collisions in handle of a knife 33.

Summary of the invention:

But the purpose of the utility model is to provide a kind of cutter phenomenon that effectively prevents to hit, and improves the efficient of production and a kind of umbrella shape tool magazine with anticollision device, collision-prevention device of security.

The purpose of the utility model is achieved in that

A kind of umbrella shape tool magazine with anticollision device, collision-prevention device; It comprises the tool magazine body, be arranged on movable door on the tool magazine body, be arranged on cutterhead and handle of a knife in the tool magazine; It is characterized in that sense switch and a data signal line of joint detection switch after being used for magazine knife-selecting and putting in place is being set on the described movable door, described data signal line is connected to the control system host of lathe.

The defective of cutter phenomenon appears hitting in tool magazine that the utility model has overcome existing numerical controlled machinery machining center often, has avoided personnel's injury that might cause aborning, can guarantee that machined production carrying out under efficient and security context.

Description of drawings:

Fig. 1 is the structural representation of tool magazine in the prior art.

Fig. 2 is the structural representation of the utility model.

Fig. 3 is the structural representation that the utility model and machining center are used.

Fig. 4 is the control flow chart of the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing 2, Fig. 3 and Fig. 4, the utility model is further explained:

The utility model is to use in existing numerical controlled machinery machining center, is about to get final product on the tool magazine position that the utility model is installed in existing numerical controlled machinery machining center.

In the present embodiment; The utility model comprises tool magazine body 6, be arranged on movable door 2 on the tool magazine body, be arranged on cutterhead 1 and handle of a knife 3 in the tool magazine; Sense switch 5 and a data signal line 4 of joint detection switch after being used for magazine knife-selecting and putting in place is being set on the described movable door 2, and described sense switch 5 is used for detecting cutterhead and on the cutter of main shaft number, whether handle of a knife 3 is housed; Described data signal line 4 is connected to the control system host of lathe, after sense switch 5 detects signal, testing result data signal line 4 is delivered in the control system, promptly on the control system host of numerical control machining center.

The tool magazine body 6 of the utility model, and movable door 2, cutterhead 1, the handle of a knife 3 that is arranged on the cutterhead are all identical with prior art.

Shown in Fig. 3 and Fig. 4, the utility model is installed on the position of numerical controlled machinery machining center 8 original tool magazines, when numerical controlled machinery machining center 8 begins to carry out tool changing; Tool magazine cutterhead 1 is after selecting cutter to put in place; If sense switch 5 detects on the cutter of main shaft No. 7 handle of a knife 3 is housed, testing result is sent in the control system through holding wire 4, and the control system sends warning; Forbid of the action of lathe execution tool magazine, prevent to hit cutter to the main shaft side shifting.Control system and warning all can be adopted existing techniques in realizing.
