Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, propose a kind of simple in structurely, design ingenious, rationally distributed, utilize three rollers that match, realize that quick, smooth and easy, little without pause point, noise, the low two rollers of vibration join the board-like automatic tool changer of bearing curve.
Technical solution of the present invention is: a kind of pair of roller joined the board-like automatic tool changer of bearing curve, comprise support body 1, but be provided with the main spindle box body 3 of lengthwise movement and the tool magazine support 2 that is fixedly installed in support body 1 upper end, on support body 1, also be hinged with tool magazine swing arm 4, be provided with disc tool magazine 5 in the lower end of tool magazine swing arm 4, it is characterized in that: described main spindle box body 3 sides are provided with curve ruler 6, be provided with big roller 7 in the side of curve ruler 6, the first trundle 8 and the second trundle 9 that coaxial rotation is arranged in disc tool magazine 5 upper supports, wherein the first trundle 8 matches with big roller 7, the second trundle 9 then matches with curve ruler 6, be provided with the first contact-making surface 10 and second contact-making surface 11 that can contact with the second trundle 9 on the curve ruler 6, and have in the horizontal difference in height between these two contact-making surfaces.
The present invention compares with prior art, has following advantage:
Two rollers of this kind of version are joined the board-like automatic tool changer of bearing curve, and it is simple in structure, design ingenious, rationally distributed.The many disadvantages that it exists for traditional curve ruler automatic tool changer, creatively design a kind of bearing curve ruler curve ruler of big roller (namely with), and be its supporting two rollers that a coaxial rotation is set, utilize the combination of two kinds of actions of interoperation of two rollers and the interoperation of big roller, two roller and curve ruler, realize that motion of main shaft drives the goal of the invention that the tool magazine swing arm swings.In the process of whole motion, two rollers only contact with the straight line portion of curve ruler and relative motion all the time, the former motion that should contact with the curved portion of curve ruler is then substituted by the relative motion between big roller and the trundle, therefore can realize on the one hand the quick acting of main shaft, the requirement of the virgin curve of curve ruler part in processing will reduce (because this part no longer is the effective exercise part) greatly on the other hand, reduced difficulty of processing, allow simultaneously whole exchanging knives process more smooth and easy, can effectively control the noise and the vibration that produce in the exchanging knives process.And its manufacture craft is simple, and is cheap for manufacturing cost, therefore can say that it has possessed multiple advantage, is particularly suitable for applying in the art, and its market prospects are very wide.
