Abstract
The utility model relates to the technical field of machine technological equipment, in particular to a clamping tool for an expansion sleeve type thin-wall outer sleeve. The clamping tool for the expansion sleeve type thin-wall outer sleeve is characterized in that the clamping tool for the expansion sleeve type thin-wall outer sleeve is provided with a clamp body, an expanding plug, an expanding spring and a clamping bolt, the clamp body is composed of a locating board, a clamping sleeve and an expanding sleeve, one end of the locating board is fixedly connected with the expanding sleeve, the other end of the locating board is fixedly connected with the clamping sleeve, a threaded through hole is formed in the center of the locating board, the inner diameter portion of the expanding sleeve is of a conic shape and is shrunk from the outer portion to the inner portion, two or more opening through grooves are formed in the circumference of the expanding sleeve, the expanding plug is of a frustum shape, the inclination of the expanding plug is identical to that of the expanding sleeve, the expanding plug is plugged in the expanding sleeve through an expanding bolt, the expanding bolt penetrates through the hole formed in the center of the expansion plug and is connected with the threaded hole in the center of the locating board in a threaded mode, the clamping bolt is sleeved with the expanding spring, one end of the expanding spring abuts against the expanding plug, and the other end of the expanding spring abuts against the locating board. The clamping tool for the expansion sleeve type thin-wall outer sleeve has the advantages of being simple in structure, free of deformation in the process of machining, capable of satisfying the requirement for accuracy and the like.
Description
Technical field
The utility model 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 overcoat barrier part, because its wall thickness is too thin, general wall thickness is less than 2mm, and add and be not only subject to clamping force distortion man-hour, and, in process, be also easily subject to heat in metal cutting to cause thermal deformation, make the dimensional accuracy of workpiece and every shaped position tolerance be difficult to guarantee.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, process indeformable, to guarantee required precision expansion sleeve type thin-walled outer sleeve clamping tooling.
The utility model solves the technical scheme that its technical problem adopts:
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 form, 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 dwindles gradually, expansion sleeve Circle-Array is shown 2 above opening grooves, 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 on fishbolt, one end and tensioner plug are inconsistent, the other end and location-plate are inconsistent, be beneficial to reach firm expansion clamping, workpiece deformation is little, accurate positioning, the effect that machining accuracy is high.
The utility model is owing to adopting said structure, have simple in structure, process indeformable, guarantee the advantages such as required precision.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: clamp body 1, tensioner plug 2, tensioning spring 3, fishbolt 4, chuck 5, workpiece 6.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further illustrated:
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 form, 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 dwindles gradually, expansion sleeve Circle-Array is shown 2 above opening grooves, the utility model preferably adopts 3 opening grooves, be beneficial to realize expansion clamping, described tensioner plug 2 is 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 centers is threaded with the screwed hole at location-plate center, tensioning spring 3 is enclosed within on fishbolt 4, one end and tensioner plug are inconsistent, the other end and location-plate are inconsistent, be beneficial to reach firm expansion clamping, workpiece deformation is little, accurate positioning, the effect that machining accuracy is high.
The utility model 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 on the expansion sleeve of clamp body 1, one end is through the location-plate location of clamp body 1, next tensioning spring 3 and tensioner plug 2 are installed respectively on fishbolt 4, and this covering device is packed in the clamp body 1 with the same conical surface, regulate again fishbolt 4, make clamp body 1 expansion, piece-holder is firm, can process, clamp body is realized holding workpiece 6 by expansion, workpiece deformation is little, and have good positioning, thereby improved machining accuracy.
The utility model is owing to adopting said structure, have simple in structure, process indeformable, guarantee the advantages such as required precision.
