Abstract
The utility model discloses a slow-down device for the extension and retraction of a cylinder piston rod. The slow-down device comprises a fixing support, a cylinder is fixedly mounted on the fixing support, an annular shallow slot is formed on a cylinder cover, a baffle plate is fixedly mounted on the fixing support at the extending end of the cylinder piston rod, a through-hole is formed in the middle of the baffle plate, a ring-shaped groove is also formed on the baffle plate, the cylinder piston rod is in sliding fit with the through-hole, a spring is sleeved in the middle of the cylinder piston rod, and two ends of the spring are positioned in the annular shallow slot and the ring-shaped groove respectively. The slow-down device for the extension and retraction of the cylinder piston rod has the advantages of simple structure, convenience in installation and use, high operating efficiency and high energy utilization ratio, ensures the machining precision through the buffer action of the spring and meets the requirement of high-precision batch production.
Description
Technical field
The utility model relates generally to numerical control machine tool changer main drive gear apparatus assembly, relates in particular to a kind of cylinder piston rod and stretches with slowing down device.
Background technology
In the prior art, the numerical control machining center lathe is when processing different shape component of machine complicated and changeable, requirement has machining accuracy height, good product quality, characteristics that production efficiency is high, therefore the Digit Control Machine Tool main drive gear is extremely important, it moves is to realize by stretching of cylinder piston rod, the existing cylinder buffer unit useless that stretches, its stretching speed is too fast, can not satisfy accurately machined requirement, in process, also can produce vibrations, waste energy, inefficiency, influence the machining accuracy of lathe, can not satisfy the high accuracy batch production requirement.
The utility model content
The purpose of this utility model is in order to remedy the deficiency of prior art, provide a kind of cylinder piston rod flexible with slowing down device, solved the flexible buffer unit useless of existing cylinder, can not satisfy accurately machined requirement, can produce vibrations, waste energy inefficiency, influence the machining accuracy of lathe, can not satisfy problems such as high accuracy batch production requirement.
The utility model is achieved through the following technical solutions:
A kind of cylinder piston rod is flexible with slowing down device, include fixed support, be installed with cylinder on the described fixed support, described cylinder cylinder cap is provided with annular shallow slot, is installed with baffle plate on the fixed support of described cylinder piston rod external part, and described baffle plate middle part is provided with through hole, also be provided with annular groove on the described baffle plate, described piston rod and through hole are slidingly matched, and are set with spring in the middle part of the piston rod, and described both ends of the spring lays respectively in annular shallow slot and the annular groove.
The utility model has slowed down the stretching speed of cylinder piston rod by the effect of spring, has improved machining accuracy, has guaranteed the stability in the process simultaneously, can not produce vibration, has improved energy utilization rate.
The utility model has the advantages that:
The utility model is simple in structure, easy to install, and the cushioning effect by spring has guaranteed machining accuracy, high efficiency, and the energy utilization rate height has satisfied the high accuracy batch production requirement.
