Abstract
The invention relates to the field of prestressing device manufacture, in particular to a clamping device. The clamping device comprises a tensioning screw and a shaft sleeve (2), wherein multiple clamp pieces (3) are further arranged at the end of the shaft sleeve (2), the shaft sleeve (2) is arranged on the outer side of the tensioning screw (1) in a sleeved mode, the end of the tensioning screw (1) is in a shape of an inverted cone, and the multiple clamp pieces (3) wrap the end of the tensioning screw (1). The clamping device is fixed through an inner hole formed in an external expansion type extrusion working clamp piece (5), is firmly fixed, does not easily loosen and is simple, efficient and accurate in positioning.
Description
Technical field
The present invention relates to stressing equipment and manufacture field, particularly relate to a kind of clamping device.
Background technology
In stressing equipment, the making of work clip sheet is comparatively difficult, because the profile of work clip sheet is taper, is difficult to fix; Cost of labor is high, fixing inaccurate.
Summary of the invention
For solving the problems of the technologies described above, the present invention proposes a kind of clamping device, described clamping device comprises stretching screw and axle sleeve, the end of described axle sleeve is also provided with multiple intermediate plate, described axle sleeve is enclosed within outside described stretching screw, the end of described stretching screw is back taper, and described multiple intermediate plate wraps up described stretching screw end.
Further technical scheme of the present invention is: the position that described axle sleeve is connected with described intermediate plate is also provided with annular boss, and described boss outer radius is greater than the inside radius of described work clip sheet.
Further technical scheme of the present invention is: described clamping device also comprises ring flange, and described ring flange connects described axle sleeve.
The invention has the beneficial effects as follows: adopt the endoporus extending out formula extruding work clip sheet to be fixed, fixation, not easily gets loose, simply efficiently, accurate positioning.
Accompanying drawing explanation
Fig. 1 is the cut-away illustration that the embodiment of the present invention provides.Stretching screw does not wherein have cutting, and in figure, dotted line is the schematic diagram that work clip sheet installs on the securing means.
Detailed description of the invention
Embodiment is as shown in the figure: a kind of clamping device, described clamping device comprises stretching screw 1 and axle sleeve 2, the end of described axle sleeve 2 is also provided with multiple intermediate plate 3, described axle sleeve 2 is enclosed within outside described stretching screw 1, the end of described stretching screw 1 is back taper, and described multiple intermediate plate 3 wraps up described stretching screw 1 end.Time described stretching screw 1 is strained, described multiple intermediate plate 3 can expand outwardly, and then the internal diameter of extruding work clip sheet 5 is with fixing described work clip sheet 5.One end that described stretching screw 1 is not provided with back taper head is fixed on the rotating disc 6 of lathe.
The position that described axle sleeve 2 is connected with described intermediate plate 3 is also provided with annular boss, and described boss outer radius is greater than the inside radius of described work clip sheet 5.Facilitate the location of described work clip sheet 5.
Described clamping device also comprises ring flange 4, and described ring flange 4 connects described axle sleeve 2.Increase inertia and the stability of described clamping device, ensure that described clamping device is applied in after on lathe and can ensure precision.
The implementation process of the present embodiment: end work clip sheet 5 being enclosed within described axle sleeve 2, the i.e. outside of intermediate plate 3, carries out tension by relatively described for stretching screw 1 axle sleeve 2 and can fix described work clip sheet 5.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
