Wherein, the parts name that Reference numeral is corresponding is called:
1-clamp body, 2-expansion sleeve, 3-cavity, 4-axis hole, 5-pore, 6-swelling piston, 7-adjusting bolt, 8-sealing ring, 9-screw plug.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, the utility model mainly is comprised of expansion sleeve 2, and these expansion sleeve 2 integral body are cylindrical structure, and these expansion sleeve 2 inside have cavity 3, and the cross section of described cavity 3 is circular.During use axle sleeve is enclosed within on this expansion sleeve and processes, be close on the sleeve lining for the ease of the sidewall with expansion sleeve 2, make 2 pairs of sleeve linings of expansion sleeve impose uniform pressure, to guarantee the clamping precision of axle sleeve, on described expansion sleeve 2, also be provided with clamp body 1.
Described clamp body 1 matches with expansion sleeve 2, and the cross section of this clamp body 1 is circular, and 2 of described expansion sleeves are enclosed within on this clamp body 1.Be provided with the passage that is connected with cavity 3 at described clamp body 1, described passage comprises axis hole 4, and the central axis of the central axis of this axis hole 4 and clamp body 1 coincides.In order to be connected with cavity 3, on described clamp body 1, also be provided with the pore 5 that is communicated with axis hole 4 and cavity 3.Described pore 5 is more than one, and is evenly distributed on the sidewall of clamp body 1, and as shown in Figure 1, and the central axis of the central axis of this pore 5 and axis hole 4 is perpendicular.
For the ease of processing axis hole 4, described axis hole 4 is made as the through hole that runs through clamp body 1 left and right sides both ends of the surface, and also is provided with the screw plug 9 of this axis hole 4 of shutoff at the port of export of this axis hole 4.For the ease of the air of pressure channel and cavity 3 inside, make the formed gas pressure of air after the compression strut expansion sleeve 2, thereby expansion sleeve 2 is close on the axle sleeve, also be provided with adjusting device at the arrival end of described axis hole 4.Described adjusting device comprises the swelling piston 6 that is arranged in the axis hole 4, and described swelling piston 6 matches with axis hole 4, and is connected on the sidewall of this axis hole 4.For better with aeroseal in cavity 3 and pore 5 and axis hole 4, on described swelling piston 6, also be provided with more than one sealing ring 8, as shown in Figure 1.
Move right for the ease of promoting swelling piston 6, thereby compressed air also is provided with adjusting bolt 7 on described swelling piston 6.For the ease of connecting adjusting bolt 7, be provided with the external screw thread that is complementary with adjusting bolt 7 at described axis hole 4, described adjusting bolt 7 be connected on the clamp body 1 after this external screw thread cooperates, namely under this adjusting bolt 7 and described externally threaded the cooperation, can make adjusting bolt 7 move left and right, thereby drive swelling piston 6 move left and right, so adjustable sealing closes the pressure of the air in clamp body 1 and expansion sleeve 2.For the ease of using spanner to turn adjusting bolt 7, on described adjusting bolt 7, also be provided with inner hexagonal hole.
During use, axle sleeve is enclosed within on the expansion sleeve 2, then use spanner turn adjusting bolt left 7, and be enclosed in air in clamp body 1 and the expansion sleeve 2 by swelling piston 6 compression, air after the compression forms an outside pressure to the sidewall of expansion sleeve 2, thereby the sidewall that promotes expansion sleeve 2 is close on the axle sleeve, then clamp body 1 clamping can be processed axle sleeve on lathe.After machining clamp body 1 is taken off from lathe, and use spanner outwards to screw out adjusting bolt 7, swelling piston 6 moves right, the volume of air of namely sealing under the effect of swelling piston 6 increases, pressure reduces, and expansion sleeve 2 is restored to the original state, thereby expansion sleeve 2 is separated with axle sleeve.
As mentioned above, just can realize preferably the utility model.
