Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.Should be understood that, detailed description of the invention described herein only, for description and interpretation the utility model, is not limited to the utility model.
The utility model provides a kind of die handle 8, and wherein, this die handle 8 comprises die handle body 1, be installed on screw die 2 on die handle body 1 and the sleeve 3 with the coaxial setting of screw die 2.
By technique scheme, with this die handle 8 of sleeve 3, can, in workpiece 7 process, prevent the effect of centrifugal force when workpiece 7 is subject to cutting force, deadweight and rotation, produce bending, vibration etc., thereby improved the qualification rate of workpiece 7.On the other hand, while having prevented that workpiece 7 is subject to thermal stretching to produce flexural deformation, workpiece is stuck in to be supported between point, thereby has also just improved operating efficiency, has reduced manufacturing cost.
As shown in Figure 1, in the time using this die handle 8, need be by workpiece 7 simultaneously through coaxial sleeve 3 and the screw die 2 arranging.Then, as shown in Figure 2, this die handle 8 is fixed on square tool post 11, one end of this workpiece 7 is fixed on lathe by chuck 9, the other end is fixing by top 10.In process, this die handle 8 can be along with square tool post 11 be along the axial direction uniform motion of this workpiece 7, simultaneously, the chuck 9 that is fixed with this workpiece 7 can be around the center line rotation of this workpiece 7, thereby realize the relative motion between die handle 8 and workpiece to be processed 7, complete the process of workpiece 7.Apparently, should there is better axiality with the die handle 8 of sleeve 3, thereby further ensure the machining accuracy of this workpiece 7.
Between sleeve 3 and die handle body 1 and between screw die 2 and die handle body 1, can connect or connect by the mode of welding by securing member.The workpiece 7 of different-diameter be can process in order to realize same die handle 8, preferably, threading die seat 4 for screw die 2 is installed and the receiver 5 for installing sleeve 3 on die handle body 1, are provided with.On die handle body 1, be fixedly installed threading die seat 4 and receiver 5 simultaneously, now describe as an example of threading die seat 4 example.This threading die seat 4 is the tubular structure being integrally formed with die handle body 1, and as shown in Figure 1, screw die 2 can be arranged to have the external diameter mating with this threading die seat 4, and internal diameter can be arranged to be of different sizes, to adapt to the different demands of different workpiece 7.Like this can be according to the process requirements of different workpieces 7, select different screw die 2 and be arranged on die handle body 1.The design principle of receiver 5 is identical with the design principle of threading die seat 4, does not repeat them here.It should be noted that, threading die seat 4, receiver 5 can be connected with die handle body 1 by connected modes such as welding or securing member connections, can be to be also integrally formed with this die handle body 1.
For the bending resistance effect of reinforcement plate retainer 8, preferably, receiver 5 is multiple.In the time using this die handle 8, workpiece 7 can pass in the plurality of receiver 5 simultaneously, thereby has avoided this workpiece 7 to bend under the effects such as gravity.The plurality of receiver 5 is coaxial setting, thereby workpiece 7 axialities that this die handle 8 is processed are better.
The spread pattern of receiver 5 and threading die seat 4, can be for to be symmetrical arranged about threading die seat 5, and preferably, as shown in Figure 1, multiple receivers 5 are arranged at respectively the both sides of threading die seat 4.
In order to simplify the symmetrical structure of above-mentioned die handle 8 and to ensure that the machined surface of workpiece 7 is stressed even around, in order to obtain better bending resistance, anti seismic efficiency, preferably, as shown in Figure 1, receiver 5 is two, and two receivers 5 are identical to the distance of threading die seat 4.
In order to meet the process requirements of the workpiece 7 that slenderness ratio is less, receiver 5 can have multiple in the distribution of threading die seat 4 every sides, preferably, the receiver 5 that is positioned at threading die seat 4 homonymies is at least two, be adjacent to distance between receiver 5 identical, and two receivers 5 adjacent with threading die seat 4 are identical to the distance of threading die seat 4.Distance between the adjacent receiver 5 arranging on die handle body 1 is all identical, to ensure the even setting of receiver 5, with meet workpiece 7 axial direction stressed evenly.
In order to meet different process requirements, the structure of die handle 7 can also be set to receiver 5 and be positioned at the homonymy of threading die seat 4, arranges, preferably but can meet evenly simultaneously, multiple receivers 5 are arranged at a side of threading die seat 4, are adjacent to distance between receiver 5 identical.
The screw die 2 of different size can be installed in order to make receiver 5 that the sleeve 3 of different size, threading die seat 4 can be installed, being connected between receiver 5 and sleeve 3, threading die seat 4 and screw die 2 can be arranged to removably connect.Preferably, as shown in Figure 1, on receiver 5 and threading die seat 4, be provided with jackscrew 6.At receiver 5(or threading die seat 4) on be provided with for jackscrew fixing screw, when by the sleeve 3(choosing or screw die 2) be installed on corresponding receiver 5(or threading die seat 4) when upper, by jackscrew precession screw, completed fixing.
For die handle 8 is fixed on lathe, preferably, die handle body 1 is provided with the mount pad being connected with lathe.When this die handle 8 is installed, this mount pad need to be fixedly mounted on the square tool post 11 on lathe.
Below describe by reference to the accompanying drawings preferred embodiment of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characterictic described in above-mentioned detailed description of the invention, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible combinations.
