Abstract
The utility model provides a floating diamond positioning pin for machining, which comprises a body and is characterized in that the body is formed by a support sleeve and a pin body arranged in an inner hole of the support sleeve. A spring is arranged at the lower end of the inner hole and abuts against the pin body, the pin body moves vertically in the inner hole under effect of the spring, a clamping groove is arranged on the pin body, a screw penetrates through the lateral face of the support sleeve to be matched with the clamping groove, and the upper end of the pin body is conical. The diamond positioning pin can float vertically, the height of the diamond positioning pin changes within a certain range, the diamond positioning pin can be matched with holes large in depth, diameter tolerance and position tolerance and is applicable to processing and positioning of workpieces of various dimensions, and the upper end of the diamond positioning pin is diamond, so that the diamond positioning pin has the function of limiting rotation of workpieces and preventing the workpieces from rotating in processing. The diamond positioning pin can be used by matching with a cylindrical positioning pin and is reliable, accurate and fast in positioning.
Description
Technical field
The utility model relates to the appurtenances of the positioning fixture that a kind of operative workpiece uses, especially mach unsteady rhombus locating stud.
Background technique
When workpiece is carried out machining, need carry out clamping and location with anchor clamps, to guarantee carrying out smoothly of processing; This positioning supports pin is adopted in location on the anchor clamps, has both had the face positioning action, has the hole positioning action again; According to the diverse location and the size of the processing positioning hole of workpiece to be processed self, choose sizeable positioning supports pin and be installed on the appropriate location of anchor clamps, play the hole positioning action.If operative workpiece positioning hole end face is the locating basis plane, then can locate with the plane of orientation on this unsteady rhombus locating stud.And the locating stud of existing technology only plays the hole positioning action, can not play the face positioning action; And its physical dimension is normally fixing, and a kind of locating stud of Dimensions can only be corresponding with a kind of workpiece positioning hole of Dimensions; When workpiece or its processing positioning hole changes; Just can not cooperate with it, need to change the locating stud that matches and to continue processing, cause its using scope narrower; In addition, need the operator often to change or adjustment positioning supports pin, consumed the regular hour, reduced labour productivity; And, for the workpiece of blank type, like foundry goods, forging etc.; Because positioning hole size and the positional deviation of workpiece are bigger, maybe be also jagged in the positioning hole, burning into sand etc., the positioning supports pin of selecting for use is possibly can't to be stretched in the positioning hole of this workpiece; Though perhaps can stretch in the positioning hole, the effect that can not play the location less than the size of positioning hole and support causes the location of workpiece to be forbidden even clamp not strongly to lean on; Influence machining accuracy, even form the processing waste product.
The model utility content
Above-mentioned deficiency to positioning supports pin in the existing technology; The main purpose of the utility model be to solve existing positioning supports pin narrower because of the using scope that fixed size causes, can not better cooperate with the positioning hole of workpiece, the workpiece locating face need be provided with problems such as positioning device in addition, can contact and have the unsteady rhombus positioning supports pin that face is located at any time with the workpiece hole inwall according to the size of workpiece positioning hole and provide a kind of.
The technological scheme of the utility model is following: a kind of mach unsteady rhombus locating stud; Comprise body, it is characterized in that said body is made up of supporting sleeve and the shank that is arranged in the supporting sleeve endoporus; Lower end at endoporus; Be provided with spring, spring withstands on the shank, and shank moves up and down in endoporus under spring action; On shank, be provided with draw-in groove, screw passes the side of supporting sleeve and matches with draw-in groove; The upper end of shank is one section taper.
Further characteristic is that the cross section of the conical section of the upper end of shank is a rhombus
One section of matching with the endoporus of supporting sleeve of shank is circular, and endoporus is a circular port.
With respect to existing technology, the utlity model has following beneficial effect:
1, the unsteady rhombus locating stud of the utility model, because of it can upper and lowerly float, it changes highly within the specific limits, can cooperate with the degree of depth and diameter tolerance hole big, that positioning tolerance is bigger, can adapt to the needs of multiple Dimensions workpiece processing and location.
2, its upper end is a rhombus, has the effect that the restriction workpiece rotates, and prevents that workpiece from adding the rotation in man-hour.Be used with cylindrical locating stud, the location is reliable, accurate, quick.
3, reduce the time of operator's replacing or adjustment positioning supports pin significantly, improved labour productivity.
4, locating stud and locating face reduce jig Design, production time together, raise the efficiency obviously.
Description of drawings
Fig. 1 is the utility model supporting pin mounting structure schematic representation;
Fig. 2 is the plan view of Fig. 1 supporting pin structure.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Like Fig. 1, shown in 2; A kind of mach unsteady rhombus locating stud, it comprises body 1, described body 1 is made up of supporting sleeve 2 and the endoporus that is arranged on supporting sleeve 23 interior shanks 4; Lower end at endoporus 3; Be provided with spring 5, spring 5 withstands on the shank 4, and shank 4 moves up and down in endoporus 3 under spring 5 effects; On shank 4, specifically at the intermediate section of shank 4, be provided with draw-in groove 6, screw 7 pass the side of supporting sleeve 2 and match with draw-in groove 6, corresponding, in screw 7 screws in draw-in grooves 6, just can limit shank 4 rotations.
The upper end of shank 4 is one section taper, and the cross section of this section taper is a rhombus, and a section of matching with supporting sleeve 2 endoporus 3 of shank 4 can be a rectangle, also can be circular or oval, considers from the fabricating cost angle, is made into circle usually; Like this section is circular, and the endoporus 3 of supporting sleeve 2 also is corresponding circular port; Like this section is rectangle or ellipse, and then the endoporus 3 of supporting sleeve 2 is corresponding rectangular opening or slotted eye (be a kind of theoretic structure, process hell to pay in the reality), can cancel draw-in groove 6 and screw 7, the ability simplified structure; Certainly, the endoporus 3 of supporting sleeve 2 also can be conventional circle, and is easy to process, fabricating cost is low.Body endoporus 3 exterior edge faces are smooth surface, below the roughness Ra1.6, are used for workpiece face location.
During work, through the lower end of supporting sleeve 2, the whole unsteady rhombus locating stud of the utility model is installed on the anchor clamps, its conical section gos deep into the location endoporus of workpiece to be processed, cooperates and locatees.During workpiece pressing, the end face of supporting sleeve 2 contacts with the workpiece plane of orientation.Thereby reach the purpose of face location.Because shank 4 moves up and down in endoporus 3 under spring 5 effects, it can adapt to the endoporus of the multiple degree of depth, multiple diameter; Screw 7 matches with draw-in groove 6 and limits shank 4 and rotate, and can prevent that workpiece to be processed from rotating.
Need to prove; Above embodiment is only in order to explain the utility model technological scheme but not the restriction technologies scheme; Although the claimant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technological schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
