Abstract
The utility relates to the field of machining and provides a fast switching device for a die set on a machine tool. The fast switching device is ingenious in structure, convenient to use and good in using effect. Two pairs of rollers are arranged at the bottom of the die set, a guide frame stretching into the machine tool is arranged on one side of the machine tool, and guide grooves used for containing the rollers are formed in the top face of the guide frame. Two pairs of floating limiting devices are further arranged in the middle of the machine tool, the distance between the two pairs of floating limiting devices is equal to the distance between the two pairs of rollers, and the floating limiting devices are connected below the guide grooves. Each floating limiting device comprises a floating limiting block, a floating piston and a hydraulic cylinder. The fast switching device for the die set on the machine tool has the advantages that machining is easy to perform, cost is saved, and machining efficiency is high.
Description
Technical field
The utility model relates to field of machining, relates in particular to the improvement for the switching device shifter proposition of the mould bases in lathe.
Background technology
At present, as the processing such as powder metallurgy occasion, conventionally before use, first processing mold is fixedly connected on mould bases, then mould bases is pushed in lathe is fixed; Thereby by mode processing to the workpiece of plurality of specifications with realization of die change.In prior art, for making the replacing of mould bases more convenient, the side at lathe is provided with leading truck conventionally, and on the end face of leading truck, installs two row's guide wheels, thereby realizes pushing fast and pulling out of mould bases, as shown in Figure 5; Yet conventionally there is following problem in this class formation: after one, mould bases pushes, cannot be to its effective fixation of mould bases; Two,, for the problems referred to above one, common solution is a height to be set on lathe lower than the installed surface of guide wheel, after mould bases pushes, is fixed on installed surface; Yet, so mould bases pull out and limit very inconvenience.
To sum up, how to make the pushing of mould bases, fixing and pull out more efficient, be stable into the technical problem urgently to be resolved hurrily for those skilled in the art.
Utility model content
The utility model is for the problems referred to above, proposed the apparatus for fast switching of a kind of delicate structure, the lathe top mold frame that easy to use and result of use is good.
The technical solution of the utility model is: the bottom of described mould bases is provided with two pair rollers, one side of described lathe is provided with the leading truck stretching in described lathe, on the end face of described leading truck, offer the gathering sill for accommodating described roller, described lathe middle part is also provided with two pairs of floating position-limiting devices, spacing between two pairs of described floating position-limiting devices is consistent with the spacing between two pairs of described rollers, and described floating position-limiting device is connected to described gathering sill below;
Described floating position-limiting device comprises floating position-limiting piece, floating piston and hydraulic cylinder, and described hydraulic cylinder is fixedly connected on described gathering sill below, described floating piston be located in described hydraulic cylinder and with described hydraulic cylinder mechanical seal; On described gathering sill, offer the telescopic hole corresponding with described Position of Hydraulic Cylinder, described floating position-limiting piece is located in described telescopic hole and is fixedly connected on the end face of described floating piston.
The height of the end face of described floating position-limiting piece progressively increases progressively along mould bases approach axis.
The end face of described floating position-limiting piece is curved.
The internal diameter of described telescopic hole is less than the diameter of described roller.
Use procedure of the present utility model can be divided into following three steps:
One, pushing of mould bases: can directly two pair rollers be embedded in gathering sill, and promote mould bases towards lathe, mould bases is entered in lathe;
Two, the use of mould bases: four hydraulic cylinder off-loads, two pair rollers are fallen and snap in telescopic hole, lathe carries out work;
Three, pulling out of mould bases: four hydraulic cylinder pressurizations, thereby by floating position-limiting piece jack-up mould bases, thereby roller is raised up to gathering sill top, and then can carry out freely pulling out to mould bases.
The utility model coordinates by roller and gathering sill, makes mould bases more easy, efficient in pushing and pulling out process.Meanwhile, when lathe is worked the roller of mould bases bottom fall and be fastened on telescopic hole in fixing to complete, and after end-of-job, can be by floating position-limiting device jack-up mould bases, freely pull out carrying out.The utility model optimized leading truck structure, reduced the quantity of roller, have the advantages that processing is simple, cost-saving and working (machining) efficiency is high.

Fig. 5 is background technology figure of the present utility model;
In figure, 1 is mould bases, the 10th, and roller, the 2nd, lathe, the 3rd, leading truck, the 30th, gathering sill, the 4th, floating position-limiting device, the 41st, floating position-limiting piece, the 42nd, floating piston, the 43rd, hydraulic cylinder.
The specific embodiment
The utility model as Figure 1-4, the bottom of described mould bases 1 is provided with two pair rollers 10, one side of described lathe 2 is provided with the leading truck 3 stretching in described lathe 2, on the end face of described leading truck 3, offer the gathering sill 30 for accommodating described roller 10, described lathe 2 middle parts are also provided with two pairs of floating position-limiting devices 4, spacing between two pairs of described floating position-limiting devices 4 is consistent with the spacing between two pairs of described rollers 10, and described floating position-limiting device 4 is connected to described gathering sill 30 belows;
Described floating position-limiting device 4 comprises floating position-limiting piece 41, floating piston 42 and hydraulic cylinder 43, and described hydraulic cylinder 43 is fixedly connected on described gathering sill 30 belows, described floating piston 42 be located in described hydraulic cylinder 43 and with described hydraulic cylinder 43 mechanical seals; On described gathering sill 30, offer the telescopic hole corresponding with described hydraulic cylinder 43 positions, described floating position-limiting piece 41 is located in described telescopic hole and is fixedly connected on the end face of described floating piston 42.
The height of the end face of described floating position-limiting piece 41 progressively increases progressively along mould bases 1 approach axis.Like this, when hydraulic cylinder pressurization jack-up floating position-limiting piece, mould bases is by the end face down sliding along floating position-limiting piece and fall into gathering sill, has the advantages that occupation mode is easy, working (machining) efficiency is high.
The end face of described floating position-limiting piece 41 is curved.Make mould bases to skid off process more smooth-going.
The internal diameter of described telescopic hole is less than the diameter of described roller 10.Like this, after two pair rollers fall, can effectively be fixed on (roller bottom is fastened on telescopic hole top) in lathe, make it cannot produce play in use.
