Abstract

The invention relates to the technical field of mechanical process devices, in particular to an expanded thin-walled outer sleeve clamping tool which is characterized by comprising a fixture body, a cone-frustum-shaped expanding plug, a tensioning spring and a clamping bolt. The fixture body comprises a positioning plate, a clamping sleeve and an expanding sleeve, one end of the positioning plate is fixedly connected with the expanding sleeve, the other end of the positioning plate is fixedly connected with the clamping sleeve, a threaded through hole is formed in the center of the positioning plate, the expanding sleeve is provided with a conical inner bore which is gradually decreased from outside to inside, a circumference array of the expanding sleeve is provided with more than two opening through grooves, the inclination of the expanding plug is as same as that of the expanding sleeve, the expanding plug is plugged into the expanding sleeve through a tensioning bolt, the tensioning bolt penetrates a hole in the center of the expanding plug and is connected with the threaded hole in the center of the positioning plate in a threaded manner, the tensioning spring sleeves the clamping bolt, one end of the tensioning spring is abutted to the expanding plug, and the other end of the tensioning spring is abutted to the positioning plate. The expanded thin-walled outer sleeve clamping tool has the advantages that the tool is simple in structure and non-deformable in machining, accuracy requirements are met and the like.

Description

Expansion sleeve type thin-walled outer sleeve clamping tooling
Technical field
The present invention relates to mechanical technology equipment technology field, specifically a kind of expansion sleeve type thin-walled outer sleeve clamping tooling.
Background technology
At present, for thin-walled outer sleeve member, because its wall thickness is too thin, general wall thickness is less than 2mm, adds and is not only subject to clamping force distortion man-hour, and, in process, also easily cause thermal deformation by heat in metal cutting, make the dimensional accuracy of workpiece and every shaped position tolerance be difficult to ensure.
Summary of the invention
The object of the invention is to solve above-mentioned the deficiencies in the prior art, provide a kind of structure simple, process indeformable, to ensure required precision expansion sleeve type thin-walled outer sleeve clamping tooling.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of expansion sleeve type thin-walled outer sleeve clamping tooling, it is characterized in that being provided with clamp body, tensioner plug, tensioning spring and fishbolt, described clamp body is by location-plate, gripping sleeve and expansion sleeve are formed, described location-plate one end is fixedly connected with tensioning sleeve, the other end is fixedly connected with gripping sleeve, location-plate center is provided with tapped through hole, described location-plate, the axis of gripping sleeve and expansion sleeve matches, described expansion sleeve internal diameter is tapered, and ecto-entad reduces gradually, expansion sleeve Circle-Array shows the opening groove of more than 2, be beneficial to realize expansion clamping, described tensioner plug is taper type, the gradient of tensioner plug is identical with expansion sleeve, tensioner plug through tensioning bolt plug in expansion sleeve, the hole that tensioning bolt is provided with through tensioner plug center is threaded with the screwed hole at location-plate center, tensioning spring is enclosed within fishbolt, one end and tensioner plug inconsistent, the other end and location-plate inconsistent, be beneficial to reach and firmly expand clamping, workpiece deformation is little, accurate positioning, the effect that machining accuracy is high.
The present invention owing to adopting said structure, have structure simple, process indeformable, ensure the advantages such as required precision.
accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numeral: clamp body 1, tensioner plug 2, tensioning spring 3, fishbolt 4, chuck 5, workpiece 6.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of expansion sleeve type thin-walled outer sleeve clamping tooling, it is characterized in that being provided with clamp body 1, tensioner plug 2, tensioning spring 3 and fishbolt 4, described clamp body 1 is by location-plate, gripping sleeve and expansion sleeve are formed, described location-plate one end is fixedly connected with tensioning sleeve, the other end is fixedly connected with gripping sleeve, location-plate center is provided with tapped through hole, described location-plate, the axis of gripping sleeve and expansion sleeve matches, described expansion sleeve internal diameter is tapered, and ecto-entad reduces gradually, expansion sleeve Circle-Array shows the opening groove of more than 2, the present invention preferably adopts 3 opening grooves, be beneficial to realize expansion clamping, described tensioner plug 2 is in taper type, the gradient of tensioner plug 2 is identical with expansion sleeve, tensioner plug 2 is filled in expansion sleeve through tensioning bolt 4, the hole that tensioning bolt 4 is provided with through tensioner plug 2 center is threaded with the screwed hole at location-plate center, tensioning spring 3 is enclosed within fishbolt 4, one end and tensioner plug inconsistent, the other end and location-plate inconsistent, be beneficial to reach and firmly expand clamping, workpiece deformation is little, accurate positioning, the effect that machining accuracy is high.
The present invention is when clamping, first the gripping sleeve of clamp body is clamped on lathe chuck 5, and mix up center, again workpiece is enclosed within the expansion sleeve of clamp body 1, one end is located through the location-plate of clamp body 1, next by tensioning spring 3 and tensioner plug 2 difference device fishbolt 4, and this covering device is loaded with in the clamp body 1 of the same conical surface, then regulate fishbolt 4, clamp body 1 is expanded, piece-holder is firm, can process, clamp body realizes holding workpiece 6 by expansion, and workpiece deformation is little, and have good positioning, thus improve machining accuracy.
The present invention owing to adopting said structure, have structure simple, process indeformable, ensure the advantages such as required precision.
