Abstract
The utility model discloses a rotary machine tool protective cover, comprising a plurality of rotary disks and protection plates of the same number of the rotary disks, a joint bearing and driving device; wherein the rotary disks are uniformly arranged on the machine tool using the main axle of the machine tool as the axle center; the protection plates are respectively mounted on the rotary disks and rotate along with the rotary disks. When the rotary disks respectively rotate towards two directions, the protection plates are integrally at open and closed state. The driving device is connected with the rotary disks to drive the operation of the protection plates. The obvious advantages of the utility model are that: the rotary machine tool protective cover is composed of a plurality of protection covers and is a split type flexible structure and has better dust-blocking effect and is convenient for assembly and disassembly; in addition, the protection angle and size is adjustable. The structure is simple, the assembly and disassembly is convenient, the operation is stable and the work efficiency and protection effect is increased.
Description
Technical field
The utility model relates to a kind of lathe, particularly a kind of machine shield.
Background technology
Machine shield is to be used in the machine cut process, the device that sheet, granular borings are protected.General large-scale Metal Cutting Machine Tool adopts the integral protection cover, but sometimes satisfying self function and saving under the condition of cost, also can adopt local protection to replace integral protection.This local requirement of shelter has adjustable space when the bigger workpiece of processing diameter difference, but existing local protective cover adjustable range is little, can not satisfy the demand of the bigger workpiece of processing diameter difference, and volume is bigger, influence the installation of workpiece, also promptly reduced working (machining) efficiency.
The utility model content
The purpose of this utility model be the protection that in process, exists at the heavy duty machine tools problem of installing and provide a kind of simple in structure, change repair convenient, and rotary machine shield with good actual use effect.
Rotary machine shield described in the utility model comprises protective plate, oscillating bearing and the drive unit of some rotating disks and equal number; Described some rotating disks are that the axle center evenly is arranged on the bed piece with the machine tool chief axis; The protective plate of equal number is installed in respectively on each rotating disk, and can rotate jointly with rotating disk, when rotating disk respectively when both direction rotates, make protective plate integral body be in the opening and closing two states; Drive unit is connected its action of driving with rotating disk.
Described drive unit can have multiple, and preferred two kinds of schemes are as follows:
A kind of drive unit comprises hydraulic jack, support, connecting rod and oscillating bearing, and hydraulic jack is fixed on the bed piece by support, and the piston rod end of hydraulic jack connects oscillating bearing, and the inner ring of oscillating bearing then is fixed on the eccentric shaft on the rotating disk.This drive unit is that each rotating disk is equipped with independently hydraulic jack driving.
Preferred drive unit then comprises hydraulic jack, support, connecting rod and oscillating bearing, hydraulic jack is fixed on the bed piece by support, the piston rod end of hydraulic jack connects oscillating bearing, the inner ring of oscillating bearing then is fixed therein on the eccentric shaft on the rotating disk, also be provided with two other eccentric shaft on this rotating disk, and link to each other by the eccentric shaft on two rotating disks of connecting rod and other respectively, this drive unit only is equipped with a cover hydraulic jack drive unit, give other rotating disk by linkage with transmission of power again, simplified mechanism.
Rotary machine shield described in the utility model is made up of the protective plate of some same structures, when hydraulic jack drives the rotating disk rotation, drives simultaneously that protective plate is opened or closed.Hydraulic jack is the total output source, and package unit rotates and drives protective plate simultaneously and rotate a certain angle and open opposite package unit closure when the oil cylinder oil return thereby piston rod promotes rotating disk when the oil cylinder oil-feed.
Remarkable advantage of the present utility model is that it is made of some groups of protective covers, is split type flexible structure, can better play retaining bits effect, and be convenient to workpiece loading and unloading; In addition, its protection angle and protection size are adjustable.Simple in structure, install and remove conveniently, operate steadily, can increase work efficiency and protection effect.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that cross-sectional view is installed in the part of Fig. 1.
The specific embodiment
Below in conjunction with Fig. 1 and Fig. 2, the utility model is described in further detail.
Rotary machine shield described in the utility model comprises three rotating disks 6, three protective plates 4, oscillating bearing 11 and drive units; Wherein three rotating disks 6 are respectively that the axle center evenly is arranged on the bed piece with the machine tool chief axis; Be installed in respectively on the rotating disk 6 separately, have three sections deep-slotted chip breakers on each rotating disk 6, deep-slotted chip breaker respectively is provided with 12, three axles connections of axle protective plate 4 separately, therefore the axle in the groove has limited the angle of rotating disk and protective plate rotation along its orbit rotation on the drive rotating disk when rotating disk 6 rotations.Rotating disk 6 when both direction rotates, makes protective plate 4 integral body be in the opening and closing two states respectively.
Drive unit comprises hydraulic jack 9, support 8, connecting rod 2 and oscillating bearing 11, and hydraulic jack 9 is fixed on the lathe bed by support 8, and oil cylinder 9 is connected by swivel nut 10 with spherical plain bearing rod end 11, and oscillating bearing 11 is fixed on the rotating disk 6.During oil cylinder 9 oil-feeds, piston rod promotes rotating disk 6 around axle 7 rotations, and connecting rod 2 transmits motion and orders about rotating disk 1,3 rotation simultaneously, so just drive on the rotating disk in the groove spool along its orbit rotation, protective plate 4 is around axle 7 Unscrews.Opposite package unit closure when the oil cylinder oil return.When the diameter of workpiece differ to, or during the protective plate wearing and tearing, can meet the demands, thereby realize the opening of protective cover, closure function by changing the protective plate 4 that is complementary with workpiece, prevent that effectively smear metal from splashing and make things convenient for the loading and unloading of workpiece.
The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, the technical scheme that these improvements and modifications and employing are equal to replacement or equivalent transformation formation all should be considered as protection domain of the present utility model.
