Described " returning " font protective cover, its further characteristics be, the connecting rod two ends form connecting hole, and the connection between the connecting rod is to rivet by means of inserting riveting parts in the connecting hole of interlinking lever end.
Described " returning " font protective cover, its further characteristics be, has diagonal on same straight line at each parallel-crank mechanism between the unidirectional bight of protective plate.
Described " returning " font protective cover, its further characteristics are that four bights of each protective plate are four square bights.
Described " returning " font protective cover, its further characteristics are, the a plurality of protective plates of this that is layering are along carrying out projection perpendicular to the direction of each protective plate, the view field of preceding one deck protective plate drops in the view field of the adjacent protective plate of back one deck, and block the view field of the endoporus of a back adjacent protective plate, connecting rod on the protective plate of bottom and the protective plate of top layer is short slightly, Duan connecting rod one end is connected the protective plate of bottom or the protective plate of top layer slightly, the other end is connected on the end of connecting rod of adjacent corners of adjacent protective plate, connecting rod on all the other protective plates between the protective plate of bottom and the protective plate of top layer is long slightly, the center of Chang connecting rod is installed in rotation on the bight of protective plate slightly, and its two ends connect the end of connecting rod of the adjacent corners of the adjacent protective plate in both sides respectively.
Described " returning " font protective cover, its further characteristics are to be the protective cover of horizontal digital-control machining center.
Described " returning " font protective cover, because the connecting rod between the adjacent corners of adjacent protective plate forms parallel-crank mechanism, parallel-crank mechanism is therefore as link gear, when in case protective plate moves (displacement protective plate), driving remaining protective plate moves together, owing to parallel-crank mechanism is all arranged in four bights, therefore, protective plate can arbitrarily move in 360 degree scopes, need be not last, down, a left side, right four direction is provided with independent protective cover respectively, therefore simple for structure clear, have simple in structure, good looking appearance, noise is little, can satisfy that lathe runs up and the requirement of processing curve.
Description of drawings
Fig. 1 is the front view that the horizontal digital-control machining center " returns " the font protective cover.
Fig. 2 is the cutaway view along A-A line among Fig. 1.
Fig. 3 is the cutaway view along B-B line among Fig. 1.
The specific embodiment
To embodiment shown in Figure 3, the horizontal digital-control machining center " returns " the font protective cover and comprises protective plate 1, protective plate 2, protective plate 3, protective plate 4, protective plate 5, protective plate 6, protective plate 7 and protective plate 8 at Fig. 1.Each protective plate has similar profile, but the size difference.Each protective plate is the Back Word type, Back Word type and non-limiting each protective plate are square, it can be the shape that is similar to the Back Word type, as shown in Figure 1, each protective plate is a flat part, and there are endoporus or square opening in the flat part center, and flat part is square in the drawings, also can be other shapes, for example each straight line be substituted with the camber line limit.Fig. 1 carries out projection with the direction perpendicular to each protective plate, and the view field of last protective plate drops in the view field of adjacent back one protective plate, and shelters from the endoporus of adjacent back one protective plate or the view field of square opening.Protective plate 1 is the cover of maximum pretective acreage, and protective plate 8 is the cover of minimum pretective acreage.Protective plate 8 is the displacement protective plate.
Each bight of each protective plate all is welded with connecting rod base plate 10, be that example describes with southwestern bight shown in Figure 1 below, two connecting rods 11 are installed on the connecting rod base plate in one bight, the end boring of connecting rod 11,10 centre-drilling holes of connecting rod base plate, straight pin is inserted in the hole on connecting rod 11, the connecting rod base plate 10, thereby two connecting rods 11 can be installed on the connecting rod base plate 10 rotationally around axis, straight pin for example is riveted joint to connecting rod to the connection of connecting rod base plate 10, but being not limited thereto, for example also can be to be threaded.Straight pin is the center of rotation of connecting rod 11 around connecting rod base plate 10 or protective plate rotation.
Continuation is with reference to Fig. 1, and the connecting rod 11 between the adjacent corners of adjacent protective plate is hinged correspondingly, and forms parallel-crank mechanism.Described hinged, be meant that two connecting rods connect rotationally around an axis, for example be riveted joint.
In preferred embodiment shown in Figure 1, the connecting rod 11 on the protective plate 1 of bottom and the protective plate 8 of top layer is short slightly, and the one end is connected on protective plate 1 or 8, and the other end is connected on the end of connecting rod of adjacent corners of adjacent protective plate.Connecting rod 11 on all the other protective plates is long slightly, and the center of long connecting rod 11 is installed in rotation on the bight of protective plate slightly, and its two ends connect the end of connecting rod of the adjacent corners of the adjacent protective plate in both sides respectively.
In preferred embodiment shown in Figure 1, a diagonal of each parallel-crank mechanism is on same straight line.
Protective plate 8 passes for axle 9, on the axle 9 cutting tool can be installed.Therefore protective plate 8 can move in a plane with the activity of axle 9.The protective cover that Fig. 1 shows moves towards northeast corner, and moves to extreme position.Axle 9 is in the man-hour that adds of carrying out complicated face, can move in the 360 degree scopes planar, and protective plate 8 also can move in 360 degree scopes with axle 9 thereupon, the mobile meeting of protective plate 8 is delivered to other protective plates by each parallel four limit mechanism, parallel-crank mechanism has played the effect of link gear, has greatly satisfied the requirement of machine tooling curved surface.
The quantity of protective plate is not limited to 8, and what of its quantity are determined by the stroke of the displacement protective plate of lathe.
