Abstract
The invention relates to an expansion sleeve clamp used for clamping and positioning of workpieces like a box body. According to the technical scheme, the expansion sleeve clamp is characterized in that a base is provided with an installation pipe being in integrated connection with the base, a tie rod is inserted and connected to the inside of the installation pipe; the top end of the tie rod extends from the top end of an inner bore of the installation pipe; the top end of the tie rod is fixedly connected with an upper taper sleeve; the taper sleeve has an inner work inclined plane being ina back taper shape; an elastic expansion sleeve is sleeved outside the installation pipe; the top end of the side wall of the inner bore of the elastic expansion sleeve has an outer work inclined plane adapted to the inner work inclined plane; and the outer work inclined plane is in the back taper shape. The invention realizes a positioning function of a work axle center only by using one power source to drive the elastic expansion sleeve to make plastic deformation expansion and contraction movement, and due to even stress and synchronous movement, the processing surfaces of parts can not bedamaged.
Description
Technical field
The present invention relates to a kind of expansion sleeve clamp that is used for the box-type workpieces clamping and positioning.
Background technology
The designing requirement of current automobile, the casing processing dimension requires more and more higher, the profile of product also becomes increasingly complex, the processing dimension tolerance of different level different spaces also contracts tighter and tighter, the drawing requirement just must just can be satisfied with the inner chamber location in the location of casing processing, an identical location benchmark requires often will locate repeatedly for the difference of processing, and this just requires the anchor clamps repetitive positioning accuracy to get well.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of only with a drive power source elastic expansion sleeve plastic deformation expanding-contracting action, realize workpiece axle center positioning function, stressed even synchronization action, expansion sleeve clamp that can not the injuring part finished surface.
According to technical scheme provided by the invention, described expansion sleeve clamp, it is included in pedestal and is provided with the mounting pipe that is connected with its one, the pull bar of in mounting pipe, pegging graft, the pull bar top ends is stretched out from mounting pipe endoporus top, is fixedly connected with tapered sleeve in the pull bar top ends, the epicone cover has the interior inclined working that is inverted cone shape, be socketed with elastic expansion sleeve outside mounting pipe, have the outer inclined working adaptive with interior inclined working on elastic expansion sleeve endoporus sidewall top, outer inclined working also is inverted cone shape.
Be provided with the anti-striker and the alignment pin of some projectioies at pedestal upper surface.The pedestal lower surface is fixed with oil cylinder, and the piston rod of described oil cylinder stretches in the mounting pipe endoporus and with the bottom of pull bar and is connected.
Has the interior auxiliary inclined-plane that is positive taper at the bottom of mounting pipe outer wall, have the outer auxiliary inclined-plane adaptive on the endoporus sidewall top of elastic expansion sleeve with interior auxiliary inclined-plane, outer auxiliary inclined-plane also is inverted cone shape, and outer inclined working with assist inclined-plane tapering equal and opposite in direction, direction opposite outward.
The present invention only uses a drive power source elastic expansion sleeve plastic deformation expanding-contracting action, has realized workpiece axle center positioning function, and stressed even synchronization action can the injuring part finished surface.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present invention.
Fig. 2 is a stereogram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: this expansion sleeve clamp is included in pedestal 10 and is provided with the mounting pipe 11 that is connected with its one, grafting pull bar 6 in mounting pipe 11, the top ends of pull bar 6 is stretched out from mounting pipe 11 endoporus tops, top ends at pull bar 6 is fixedly connected with tapered sleeve 3 by nut 7, has packing ring 8 between the bottom of last tapered sleeve 3 and mounting pipe 11 contact portions, last tapered sleeve 3 has the interior inclined working 3a that is inverted cone shape, outside mounting pipe 11, be socketed with elastic expansion sleeve 2, endoporus sidewall top at elastic expansion sleeve 2 has the outer inclined working 2a adaptive with interior inclined working 3a, and outer inclined working 2a also is inverted cone shape.
Be provided with the anti-striker 12 and alignment pin 9 of some projectioies at the upper surface of pedestal 10.The lower surface of pedestal 10 is fixed with oil cylinder 4, and the piston rod 5 of described oil cylinder 4 stretches in mounting pipe 11 endoporus and with the bottom of pull bar 6 and is connected.
Has the interior auxiliary inclined-plane 11a that is positive taper at the bottom of mounting pipe 11 outer wall, have the outer auxiliary inclined-plane 2b adaptive with interior auxiliary inclined-plane 11a on the endoporus sidewall top of elastic expansion sleeve 2, outer auxiliary inclined-plane 2b also is inverted cone shape, and outer inclined working 2a and outer auxiliary inclined-plane 2b tapering equal and opposite in direction, direction are opposite, can make elastic expansion sleeve 2 swell synchronously in real time, dwindle, avoid swelling, dwindle and occur taper when asynchronous.
The course of work of the present invention is as follows:
When oil cylinder 4 actions, during pull bar 6 indentations, tapered sleeve 3 moves down in the drive, press down simultaneously by the interior inclined working 3a of last tapered sleeve 3 top ends and the outer inclined working 2a promotion elastic expansion sleeve 2 of elastic expansion sleeve 2 top ends, when the interior auxiliary inclined-plane 11a of mounting pipe 11 bottoms contacts fully with the outer auxiliary inclined-plane 2b of resilient sleeve 2 bottoms, force the outer inclined working 2a of elastic expansion sleeve 2, inclined working 3a, interior auxiliary inclined-plane 11a two inclined-plane external force and evenly finally lock product up and down in auxiliary inclined-plane 2b is subjected to simultaneously outward to outside distending.On the contrary, when piston rod 5 stretched out, elastic expansion sleeve 2 was by self plastic deformation, returned original state and product disengages.
