Abstract
A clamp for processing a shaft sleeve is characterized by comprising an expansion-type jacket, a gyration center and a conical core which is fixed on a chuck, wherein the expansion-type jacket comprises an inner conical mouth, a cylinder wall and a base which is provided with a bottom conical hole, the wall body of the cylinder wall is provided with an axial notch, the expansion-type jacket is connected with the gyration center through the bottom conical hole, the size of an outer circle of the cylinder wall is matched with the size of an inner circle of the shaft sleeve, and the taper of the conical core is matched with that of the inner conical mouth. An improvement of the clamp is that: the base is fixedly connected with the gyration center through a tightening screw which is arranged inside the bottom conical hole in a penetrating way. Due to adoption of the clamp, under the situation that the processing precision is guaranteed, the processing of the outer circle of the shaft sleeve can be completed at a time, and the clamp is convenient to operate, and the work efficiency of the clamp can be improved by 10 times.
Description
Technical field
The utility model relates to a kind of anchor clamps of processing axle sleeve, the especially a kind of anchor clamps that can disposablely finish sleeve outer circle processing.
Background technology
The axle sleeve processing of prior art needs repeatedly to clamp workpiece and changes cutter on lathe, cause working (machining) efficiency low.
The utility model content
Problem to be solved in the utility model is to provide a kind of anchor clamps that are used to process axle sleeve, can disposablely finish sleeve outer circle processing under the situation that ensures precision, and it is easy to operate, and work efficiency significantly improves.
The utility model adopts following technical scheme: comprise expansion chuck chuck, live centre, be fixed in the awl core on the chuck, described expansion chuck chuck comprises inner cone mouth, barrel and is provided with the base in base cone hole, the wall body of described barrel is provided with axial notch, described expansion chuck chuck is connected with live centre by the base cone hole, the interior round size of the excircle dimension of described barrel and axle sleeve is complementary, and the tapering of the tapering of described awl core and inner cone mouth is complementary.Its principle is: after the axis hole of axle sleeve machines, pack workpiece on the expansion chuck chuck in the direct-axis hole, it between the barrel of axis hole and expansion chuck chuck the sliding matching structure of size coupling, shake tailstock tool and advance workpiece, because expansion chuck chuck, core is coaxial is laid on the support for live centre and awl, the awl core promptly heads on the inner cone mouth of expansion chuck chuck, because axial notch is divided into several holding pieces with barrel, live centre continues the application of force, several holding pieces promptly slightly outwards open and compress shaft hole inner wall, thus the clamping action of performance expansion chuck chuck, after clamping is fastening, the excircle part of axle sleeve is in free of obstacles, can disposablely finish sleeve outer circle processing.
A kind of improvement is that described base and live centre are fixed by a trip bolt that is arranged in the center taper hole.Its structure is simpler.
Adopt the utility model, under the situation that ensures machining accuracy, can disposablely finish sleeve outer circle processing, it is easy to operate, and work efficiency can improve 10 times.

Fig. 3 is the right TV structure schematic diagram of Fig. 2.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of embodiment of the utility model comprises expansion chuck chuck 1, live centre 2, is fixed in the awl core 4 on the chuck 3, described expansion chuck chuck 1 comprises inner cone mouth 5, barrel 7 and is provided with the base in base cone hole 8, the wall body of described barrel 7 is provided with axial notch 9, described expansion chuck chuck 1 is connected with live centre 2 by base cone hole 8, the interior round size of the excircle dimension of described barrel 7 and axle sleeve 11 is complementary, and the tapering of the tapering of described awl core 4 and inner cone mouth 5 is complementary.Its principle is: after the axis hole of axle sleeve 11 machines, pack workpiece (axle sleeve 11) on the expansion chuck chuck 1 in the direct-axis hole, it between the barrel 7 of axis hole and expansion chuck chuck 1 sliding matching structure of size coupling, shake tailstock tool and advance workpiece, because expansion chuck chuck 1, live centre 2 and awl core 4 coaxial being laid on the support, awl core 4 promptly heads on the inner cone mouth 5 of expansion chuck chuck 1, because axial notch 9 is divided into several holding pieces 10 with barrel 7, live centre 2 continues the application of force, several holding pieces 10 promptly slightly outwards open and compress shaft hole inner wall, thereby the clamping action of performance expansion chuck chuck 1, after clamping is fastening, the excircle part of axle sleeve 11 is in free of obstacles, can disposablely finish the processing of axle sleeve 11 cylindricals.
As shown in Figure 1, a kind of improvement is that described base and live centre 2 are fixing by a trip bolt 12 that is arranged in base cone hole 8.Its structure is simpler.
As shown in Figure 2, also comprise the guiding position of being located on the barrel 76.The size of guiding position 6 is more smaller than barrel 7 excircle dimensions, is convenient to introduce workpiece.
As shown in Figure 3, the quantity that is provided with of described axial notch 9 is 6.
With the equivalent transformation of the similar homogeneous structure of utility model, all fall into protection domain of the present utility model.
