Abstract
The invention relates to an elastic locating pin without gas damping. A seat body is fixedly arranged on a clamping member; a slide opening is formed through the inside of the seat body; a locating pin body, the top end of which extends out of the seat body, is connected in a sliding manner in the slide opening; a limit bulge is arranged on the hole wall of the slide opening; correspondingly, a limit convex ring matched with the limit bulge is arranged on the outer wall at the bottom end of the locating pin; an adjusting nut is in bolt connection with the bottom end part of the slide opening to form a spring cavity between the adjusting nut and the locating pin; an offsetting spring is arranged in the spring cavity; the top end of the offsetting spring supports the bottom end face of the locating pin; the bottom end part of the offsetting spring supports the top end face of the adjusting nut; a mounting hole that communicates with the atmosphere is formed on the clamping member; the bottom end of the seat body is plugged in the mounting hole; a through-hole that leads the mounting hole to communicate with the spring cavity is formed on the adjusting nut. The spring cavity communicates with the external atmosphere, so that no gas damping exists when the locating pin moves up and down, and the up and down movement of the locating pin is flexible.
Description
Technical field
The present invention relates to a kind of locating stud, especially a kind of elastic positioning pin without gas damp.
Background technique
Fine positioning and coarse positioning are divided in the anchor clamps location, and fine positioning generally is used for the location in workpiece fine finishing hole, and coarse positioning generally is used for the location in workpiece blank hole.What coarse positioning adopted is elastic positioning pin, it is a tolerance of size of eliminating the workpiece blank hole with the tapering of locating stud, at present, general elastic positioning pin is at spring chamber and adjust formation semitight cavity between the screw, there is air in the cavity, when locating stud moves up and down, cavity volume changes, gas moment formation high pressure or negative pressure in the chamber, become air damping, influence the flexible motion of locating stud, when forming negative pressure, can attract cutting fluid and foul to enter slide opening, and then the accuracy of influence location.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of spring chamber to be communicated with, do not have air damping when making that locating stud moves up and down, elastic positioning pin flexibly moves with ambient atmosphere.
According to technological scheme provided by the invention, on anchor clamps, fixedly install pedestal, offer the slide opening that runs through in the pedestal, the location shank of pedestal is stretched out on the top that is slidingly connected in the slide opening, the hole wall of slide opening is provided with spacing preiection, correspondingly, outer wall is provided with the position limiting convex ring that spacing preiection cooperates in shank bottom, location, the slide opening bottom adjustment nut that is spirally connected, make to adjust between nut and the location shank and form spring chamber, in spring chamber, be provided with Returnning spring, described Returnning spring tip portion withstands on location shank bottom end, and the Returnning spring bottom withstands on the top end of adjusting nut, offers the mounting hole that connects atmosphere on anchor clamps, the bottom of described pedestal is plugged in the mounting hole, and is adjusting the intercommunicating pore that offers connection mounting hole and spring chamber on the nut.
In the slide opening of pedestal tip portion, be provided with dust ring.Be provided with depression upwards in shank bottom, location, described Returnning spring top embeds in this depression.Anchor clamps under the adjustment nut offer the handle hole that is communicated with mounting hole.
Spring chamber among the present invention is communicated with ambient atmosphere, and making does not have air damping when locating stud moves up and down, and locating stud moves up and down flexibly.
Description of drawings
Fig. 1 is an overall structure schematic representation of the present invention.
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: on anchor clamps 7, fixedly install pedestal 5 by screw 6, offer the slide opening 8 that runs through in the pedestal 5, the location shank 1 of pedestal 5 is stretched out on the top that is slidingly connected in the slide opening 8, the hole wall of slide opening 8 is provided with spacing preiection 14, correspondingly, shank 1 bottom outer wall is provided with the position limiting convex ring 15 that cooperates with spacing preiection 14 in the location, slide opening 8 bottoms are spirally connected and adjust nut 4, make to adjust between nut 4 and the location shank 1 and form spring chamber 9, in spring chamber 9, be provided with Returnning spring 3, described Returnning spring 3 tip portion withstand on location shank 1 bottom end, Returnning spring 3 bottoms withstand on the top end of adjusting nut 4, offer the mounting hole 10 that connects atmosphere on anchor clamps 7, the bottom of described pedestal 5 is plugged in the mounting hole 10, and is adjusting the intercommunicating pore 11 that offers connection mounting hole 10 and spring chamber 9 on the nut 4.
In the slide opening 8 of pedestal 5 tip portion, be provided with dust ring 2.Be provided with depression 12 upwards in shank 1 bottom, location, described Returnning spring 3 tops embed in this depression 12.Anchor clamps 7 under adjustment nut 4 offer the handle hole 13 that is communicated with mounting hole 10.
The present invention makes a call to an intercommunicating pore 11 in the middle of adjusting nut 4, allow the spring chamber 9 and the mounting hole 10 of anchor clamps 7 connect, and connects because of mounting hole 10 and atmosphere again, make when location shank 1 moves up and down,, can not form high pressure or negative pressure because spring chamber 9 is connected with atmosphere, no air damping, motion are flexibly.And the protection of dust ring 2 is arranged, cutting fluid and foul are difficult to enter slide opening 8, can not influence the positioning action of elastic positioning pin body 1.
