Abstract
The utility model discloses a chain-type tool magazine which comprises a rack, wherein a driving wheel and a driven wheel which are connected through a transmission chain are transversely arranged at both ends of the rack, a plurality of casing frames are fixedly connected on the transmission chain, sleeves which are used for fixing cutters are hinged on the casing frames, and an air cylinder which is used for driving the sleeves to rotate around hinged points is fixedly installed above the rack. The air cylinder drives the sleeves of clamping and holding cutters in a fixed point, travel of a manipulator is fixed, and workload of programming and designing is reduced greatly.
Description
Technical field
The utility model relates to a kind of tool magazine, relates in particular to a kind of magazine that can automatically release cutter.
Background technology
Raising along with the requirement of machining accuracy and efficient, machining center by computer programming control more and more comes into one's own, be variation and the efficient that increases, usually machining center need to be provided with the tool magazine that can hold tens of kinds of cutters, this tool magazine usually and manipulator be used, automatically get cutter and tool changing.
A kind of magazine of the prior art comprises two sprocket wheels, between two sprocket wheels the chain group is arranged, and the chain group is formed by some cutter holders unit serial connection.According to staff's needs, from tool magazine, get cutter by different order-driven manipulators, the shortcoming of this magazine has:
1, the cutter on the diverse location need to go to finish to the different stroke of manipulator, has increased the workload of programming or design;
2, connect by sprocket wheel, the walking precisely and can produce inertia force of the cutter on the sprocket wheel, larger with the site error of the gripping of manipulator.
The utility model content
The technical problems to be solved in the utility model provides a kind of magazine, and this magazine, manipulator are got different cutters not to be needed repeatedly to programme, and can improve the precision height.
For addressing the above problem, the utility model provides a kind of magazine, it comprises frame, the two ends of described frame are horizontal driving wheel and the driven pulley that has by the driving-chain connection respectively, be connected with some sleeve racks on the described driving-chain, be hinged with the sleeve for fixed cutting tool on the described sleeve rack, the top fixed installation of described frame is useful on the pushing set cylinder around the pin joint rotary cylinder.
As further improvement of the utility model, even calibration is furnished with straight pin on the circumference of described driving wheel one side, there is a camshaft described driving wheel top, described camshaft is provided with a both ends open and inc screw type convex ridge, described camshaft and described straight pin Vertical Meshing.
As further improvement of the utility model, first sensor and the second sensor are arranged respectively on the longest travel point of cylinder arm and the shortest route point.
As further improvement of the utility model, during the rotation of sleeve and sleeve rack away from two ends be fixed with an elastic component.
Beneficial effect:
(1) the cylinder fixed point promotes the sleeve of holding cutter, and the manipulator stroke is fixed, and has greatly reduced the workload of programming or design;
(2) camshaft is made continuous rotation, promote the dividing movement that driving wheel is done expection by the helical curve convex ridge on the camshaft, make walking of chain more accurate, the planar section on the camshaft makes driving wheel static, and the location self-locking, reduce the error of tool position and manipulator gripping position;
(3) stroke of cylinder is controlled by sensor, and it is more accurate to move;
(4) flexible member between sleeve and sleeve rack, when cylinder arm withdrawed from, sleeve can automatically reset.
Description of drawings
Fig. 1 is the structural representation of the utility model magazine.
Fig. 2 is the sketch of position relationship between reflection Fig. 1 middle sleeve, sleeve rack and elastic component.
Fig. 3 is the sketch of position relationship between cylinder, first sensor, the second sensor among reflection Fig. 1.
Comprise: frame 1, driving wheel 2, straight pin 21, camshaft 3, convex ridge 31, motor 4, chain 5, driven pulley 6, sleeve 71, sleeve rack 72, elastic component 73, cylinder 8, cylinder arm 81, first sensor 9, the second sensor 10.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Such as Fig. 1, Fig. 2 and shown in Figure 3, the utility model magazine comprises frame 1, and there is driving wheel 2 and the driven pulley 6 that connects by chain 5 at the two ends of frame 1, are furnished with some sleeve racks 72 on the chain 5, each sleeve rack 72 and sleeve 71 hinged forming, sleeve 71 can rotate around pin joint.Rotatablely moving of sleeve relies on cylinder 8 to finish, cylinder 8 is fixed on frame 1 top, cylinder 8 should be suitable with sleeve 71 in the position of short transverse, the position of cylinder 8 horizontal directions can be according to the set positions of manipulator gripping, the stroke of cylinder arm 81 is on this gripping point, during cylinder 8 acting, cylinder arm 81 travels forward, and promotion sleeve 71 rotates around pin joint when contact with sleeve 71.Cutter is fixed in the sleeve 71, and after sleeve 71 is reversed, cutter will be aimed at manipulator.On the cylinder arm 81 the longest strokes first sensor 9 is arranged, the second sensor 10 is arranged, the longest stroke and the shortest route of control cylinder arm 81 on the shortest route.72 of sleeve 71 and sleeve racks also are connected with flexible frame 11, when elastic component 73 is fixedly connected on sleeve 71 with sleeve rack 72 rotation away from two ends, when sleeve 71 rotates under the effect of cylinder arm 81, elastic component 73 will be elongated, when cylinder arm 81 withdrawed from, sleeve 71 is homing under the effect of elastic component.The circular motion of driving wheel 2 is that the camshaft 3 by being connected with motor 4 is realized, camshaft 3 comprises the planar section that the curved sections that formed by a linear convex ridge 31 of helical curve and other positions form.The upper surface calibration of driving wheel 2 is furnished with a circle straight pin 21, camshaft 3 and straight pin 21 Vertical Meshing, the curved sections of camshaft 3 contoured surfaces is ordered about straight pin 21 and is driven driving wheel 2 transpositions, planar section makes driving wheel 2 static, and location self-locking, thereby so that the cutter on the chain 5 is located accurately, reduce the error with manipulator gripping position.
The above describes in detail embodiment of the present utility model by reference to the accompanying drawings, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
