Abstract
The utility model provides a thin wall spare mills uses follow -up support fixture, including support, bearing pole and cylinder, bearing pole lower extreme is fixed with the bearing through the bearing position ring, and wherein cylinder one end hinges in the support, and the other end hinges in the bearing pole, and is articulated through first connecting rod and second connecting rod between support and the bearing pole. The utility model discloses can effectively reduce the work piece that mills the in -process and warp, improve the work piece machining precision.
Description
Technical field
The utility model relates to milling tool field, specifically the servo-actuated support fixture of a kind of thin-wall part milling.
Background technology
The application of thin-wall part in modern aerospace field is increasingly extensive, but due to Thin-walled Workpiece complex structure, poor rigidity, under cutting force effect, easily produces larger machining deformation, is difficult to the machining accuracy ensureing workpiece.During high-rate wireless LAN thin-walled frame clsss part, due to the removal of material, the rigidity of workpiece changes thereupon, and cutting force causes workpiece deformation to cause the change of actual milling depth, finally causes Workpiece Machining Accuracy undesirable.
Utility model content
The utility model, in order to solve the problem of prior art, provides the servo-actuated support fixture of a kind of thin-wall part milling, effectively can reduce the workpiece deformation in milling process, improves Workpiece Machining Accuracy.
The utility model comprises support, bearing rod and cylinder, and bearing rod lower end is fixed with bearing by bearing positioning ring, and wherein cylinder one end is articulated with support, and the other end is articulated with bearing rod, between support and bearing rod by first connecting rod and second connecting rod hinged.
Further improvement, described bearing outer ring is coated with bearing encapsulate, for the protection of institute's the treatment of surfaces of components.
The utility model beneficial effect is: effectively can reduce the workpiece deformation in milling process, improves Workpiece Machining Accuracy.

Fig. 4 is schematic diagram when stretching out in utility model works process.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Front view of the present utility model and top view respectively as depicted in figs. 1 and 2, comprise fixed part, support portion and pars contractilis.Fixed part is support 1, and support portion is bearing rod 4, and pars contractilis is cylinder 5 and connecting rod, and wherein cylinder 5 one end is articulated with support 1, and the other end is articulated with bearing rod 4, between support 1 and bearing rod 4 by first connecting rod 2 and second connecting rod 3 hinged.Bearing rod 4 lower end is fixed with rolling member 6 by locking member 7, and wherein said rolling member 6 is bearing, and bearing 6 outer ring is coated with bearing encapsulate 8.Described locking member 7 is bearing positioning ring.
Fixed part of the present utility model is installed on lathe headstock 9 place, ensures that fixture can move along with axis feeding, and relative with tool sharpening position fixing.
A kind of specific works process of the present utility model as shown in Figure 3 and Figure 4, is adjusted the gap that cylinder push-rod stretches out rear support bearing and cutter 10 tool, is installed following pneumatic fixture.If do not use following pneumatic fixture to support during milling thin-wall workpiece 11 sidewall, visible work-piece, by cutting force effect, is out of shape (as shown in Figure 3) to cutter 10 opposite side.When feed is to the region of poor rigidity, use following pneumatic fixture, by the thrust of cylinder extension bar, sidewall side (as shown in Figure 4) is close to by bearing.Bearing surface encapsulate for the protection of institute's the treatment of surfaces of components, and can reduce between air-actuated jaw and workpiece and vibrates.Sidewall is subject to the thrust of spring bearing, and distortion reduces, and the wall thickness after processing can keep even.
The utility model embody rule approach is a lot; the above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
