Abstract
The utility model belongs to the numerical control machine field, in particular relates to a protective door of a numerical control machine, which comprises a machine shield, protective doors, a protective door guide rail, a hoisting cable, pulley blocks, etc. The protective doors are arranged on the protective door guide rail which is arranged on the machine shield. One protective door is connected with the pulley blocks, the hoisting cable is connected with the other protective door round one pulley block and is wound on the other pulley block, and two ends of the hoisting cable are connected with the machine shield to form a closed path. The protective door has the advantages of simple structure, convenient operation, high working efficiency, small occupation area, and large effective open area, and is applicable to a middle-small numerical control machine.
Description
Technical field:
The utility model belongs to machine tool field, particularly relates to a kind of protective door of Digit Control Machine Tool.
Background technology:
The protective door of existing Digit Control Machine Tool adopts when biparting, and following several scheme is arranged: the one, and, two fan doors are respectively with manually opening and closing inconvenience, inefficiency.The 2nd,, adopt linkage, by pulley assembly bivalve door is moved round about, open and close when finally realizing protective door.The protective door floor space of this scheme is big, and effectively open area is little, is not suitable for middle-size and small-size Digit Control Machine Tool.
Summary of the invention:
Technical problem to be solved in the utility model is the shortcoming that overcomes prior art, and a kind of handled easily, high efficiency, Digit Control Machine Tool protective door that little, the effective open area of floor space is big are provided.
The technical solution of the utility model is summarized as follows:
A kind of biparting door of linked protection in the same way of Digit Control Machine Tool is characterized in that it is made up of machine shield, protective door, protective door guide rail, steel wire rope, pulley assembly etc.Protective door is installed on the protective door guide rail, and the protective door guide rail is installed on the machine shield; One fan protective door is connected with assembly pulley; Steel wire rope is walked around an assembly pulley and is connected with another fan protective door, and on another assembly pulley; The two ends of steel wire rope are connected with machine shield, form a closed-loop path.When switch one fan protective door, drive the steel wire rope motion, move thereby spur another fan protective door, two fan doors are realized interlock, open together, close together.
The utility model also can pass through oil cylinder (or cylinder) and drive.Oil cylinder (or cylinder) can be installed on the fan protective door, when oil cylinder (or cylinder) move, promote coupled protective door and move, and then spur an other fan protective door by steel wire rope and move, two fan door realizations link in the same way.
The utility model is simple in structure, and is easy to operate, and bivalve door links in the same way, high efficiency, and little, the effective open area of floor space is big.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an example structure schematic diagram of the present utility model.
Wherein, 1 be machine shield, 2 and 3 for pulley assembly, 4 are the protective door guide rail for steel wire rope, 5 and 6 is respectively two fan protective doors, 7,8 be oil cylinder (or cylinder), 9,10,14 and 15 be bolt, 11 be that little line is taken turns, 12 is the extension spring link plate, 13 is extension spring.
The specific embodiment:
As shown in Figure 1, the utility model is made up of machine shield 1, pulley assembly 2 and 3, steel wire rope 4, protective door 5 and 6, protective door guide rail 7 etc.Wherein, protective door 5 and 6 is installed on the protective door guide rail 7, and protective door guide rail 7 is installed on the machine shield 1; One fan protective door 5 is connected with 3 with assembly pulley 2; Steel wire rope is walked around an assembly pulley 2 and is connected with another fan protective door 6, and on another assembly pulley 3; The two ends of steel wire rope 4 are connected with machine shield 1, form a closed-loop path.When switch protective door 6, drive steel wire rope 4 motions, thereby pulling protective door 5 moves, two fan doors are realized interlock, open together, close together.
Because pulley assembly 2 and 3 be movable pulley, so protective door 5 and 6 moves in the same way, and protective door 6 displacement of moving is 2 times of protective door 5.Like this, after bivalve door linked in the same way, after protective door 5 and 6 can be hidden in machine shield, the area of machine shield was about 3 times of protective door area; And the two-way linkage protective door structure of same specification, the area of its machine shield is about 4 times of protective door area.As seen, adopt the Digit Control Machine Tool of the utility model structure littler than the Digit Control Machine Tool floor space that adopts existing two-way linkage protective door structure.
As shown in Figure 2, pulley assembly 2 and 3 is installed on the protective door 5, and screw 15 links to each other with protective door 6, and screw 9 and 10 is installed on the machine shield 1; Protective door 5 and 6 is installed on the protective door guide rail 7, and protective door guide rail 7 is installed on the machine shield 1.When switch protective door 6, drive steel wire rope 4 motions, thereby pulling protective door 5 moves, two fan doors are realized interlock, open together, close together.
The structure that extension spring link plate 12, extension spring 13 and little line wheel 11 are formed is used to guarantee that steel wire rope 4 is in tensioning state all the time.
