In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model arm support part floating support clamping fixture embodiment;
Fig. 2 is in the utility model arm support part floating support clamping fixture embodiment, the structural representation of the 3rd detent mechanism;
Fig. 3 is in the utility model arm support part floating support clamping fixture embodiment, the structural representation of self-correcting type locating pad.
The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
With reference to Fig. 1, show the structural representation of the utility model arm support part floating support clamping fixture embodiment.
The utility model arm support part floating support clamping fixture embodiment comprises: the supporting mechanism, hold-down mechanism, the first detent mechanism and the second location and the clamp mechanism that are fixedly connected on platen.Wherein, hold-down mechanism is used for workpiece is compressed on supporting mechanism and locates; The first detent mechanism is fixedly connected on the workbench of lathe, is used for workpiece is positioned over supporting mechanism; Second locates and clamp mechanism, is fixedly connected on the workbench of lathe, is used for position centering before and after workpiece is clamped.
As can be seen from Figure 1, in this embodiment, supporting mechanism is that foundary weight 3, the first detent mechanism are that first backstay 5, the second location and clamp mechanism are centering vice 4 for adjustment parallels 2, hold-down mechanism.
The arm support workpiece lies against through first backstay 5 and adjusts on parallels 2, and then, with centering vice 4, being felt relieved in position before and after workpiece clamps, and guarantees that machining hole is vertical with machine tool chief axis; Afterwards, with foundary weight 3 from top with position compression, location, locked before and after workpiece.This shows, the present embodiment provides the scheme that clamps of a kind of high accuracy, high rigidity and high reliability by first backstay 5 and centering vice 4 for the processing of overlength arm support workpiece.And simple in structure, assembling is easy, and the cost of mechanical type positioning clamping is low, and versatility is good, can be used for the clamping processing of the arm support product of one species different size.
Need to prove, in this embodiment:
The first, guiding mechanism selection adjustment parallels is only a kind of concrete implementation, for a person skilled in the art, though other can realize that the mechanism that adjusts the parallels function lists one by one at this, also within protection domain of the present utility model.
The second, hold-down mechanism also may not be certain necessarily to select foundary weight, for a person skilled in the art, as long as can realize that although other mechanisms of foundary weight function do not list one by one, also within protection domain of the present utility model.
Three, in the present embodiment, the first detent mechanism is first backstay,, for a person skilled in the art, as long as can realize that just although other mechanisms of backstay function do not list one by one, but also within protection domain of the present utility model.
Four, in the present embodiment, the first detent mechanism is the centering vice,, for a person skilled in the art, as long as although other mechanisms of the vice function that can realize feeling relieved do not list one by one, but also within protection domain of the present utility model.
Referring again to Fig. 1, the present embodiment arm support part floating support clamping fixture also comprises the 3rd detent mechanism, is connected in the front supporting plate 1 of lathe and the workbench of lathe, is used for clamping the cutting position, part of arm support workpiece.The effect of the 3rd detent mechanism is, with the working position of workpiece along multiple directions hold out against, locked, further guarantee the processing rigidity that the arm support part is enough.
With reference to Fig. 2, in the utility model arm support part floating support clamping fixture embodiment, the structural representation of the 3rd detent mechanism.
The 3rd detent mechanism comprises front end positioning screw 8, upper end positioning screw 9, lower end positioning screw 10 and bottom righthand side positioning screw 11.These four positioning screws with the working position four direction hold out against, locked, guarantee enough processing rigidity.
In the process of jib product, because the cutting force of part is very large, and the jib product is weldment, local welding technique is poor, and deflection is large, and product bore hole position and precision have certain deviation, and two holes are oblique layout, local holding area is few, and the clamping distortion is large, carries out the part with self-correcting type locating pad shown in Figure 3 and clamps, the self-correcting type location is lined with the wallowing motion ability, therefore as fixing or can distortion when supporting, generally, tiltangleθ be 9 degree left and right.
Further, the end of self-correcting type locating pad is band sawtooth locating pin, this band sawtooth locating pin constraint workpiece, and local deformation can not occur in workpiece in processed process, and clamp precision is high.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
