Abstract
The utility model discloses a novel type positioning pin comprising a positioning sleeve fixedly connected with a checking fixture, a T shaped holding cavity arranged inside the positioning sleeve and travelling from the upper end to the lower end of the positioning sleeve, a positioning pin rod flexibly arranged inside the holding cavity of the positioning sleeve and the top thereof extends out of the top of the positioning sleeve, and a pressure spring also arranged inside the holding cavity of the positioning sleeve and the two ends thereof respectively abut against and cooperate with the bottom of the positioning pin rod and the plug screw top of the pressure spring. In comparison with the prior art, the positioning pin provided hereby has the following beneficial effects: 1. generally having a simple and proper structure; easy and convenient to be assembled; 2. capable of positioning correctly and precisely; reliable and practical, thereby reducing unnecessary economical losses.
Description
Technical field
The utility model relates to a kind of locating stud, belongs to cubing location product technical field, refers in particular to a kind of novel locating stud.
Background technique
As described in Figure 1, locating stud is the part that anchor clamps and cubing play the role of positioning to workpiece, at present, in the cubing design, each position of locating stud all is integrated, is processed by same blank, and there is following defective in this project organization: 1, the positioning part of locating stud is cylindrical, this just requires the accuracy of manufacturing of its external diameter higher, when external diameter was excessive, workpiece failed to lay down, when external diameter is too small, the location is inaccurate, and whether qualified generation is judged by accident to product in meeting in the measuring phase; 2, locating stud is fixed on the cubing, can't on short transverse, move freely, when detected workpiece is the blank of casting, positioning hole certainly exists a pattern draft, this pattern draft can make the size of positioning hole produce fluctuation, when workpiece is put on the locating stud, because the fluctuation of hole dimension, disturbs even cause judging by accident judging that whether qualified product can cause in the when of equally; 3, be formed in one owing to each one of locating stud, the positioning part of locating stud is fixed on the support, both have not had the gap that relatively moves, in testing process, will not be suitable for that a part of product rejection of relatively independent principle, thereby manufacturing enterprise is caused damage being applicable to maximum material principle.
The model utility content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, provide a kind of simple and reasonable, the location is correct, the novel locating stud of practical and reliable.
To achieve these goals, the utility model is realized by following technological scheme:
A kind of novel locating stud, it comprises :-setting sleeve, to fixedly connected with cubing, its inside is provided with runs through the holding cavity that is " protruding " type structure at two end part up and down;-positioning pin rod, activity are installed in the holding cavity of setting sleeve and stretch out from the setting sleeve upper end portion at its top;-stage clip is built in the holding cavity of setting sleeve, its two end part respectively with the bottom and the stage clip plug screw contact contact matching of positioning pin rod.
Further, described positioning pin rod includes guide portion, positioning part and slide part in regular turn, wherein, the cylindrical structure of guide portion and slide part, the positioning part is conical structure.
Further, the length of described positioning part is less than the maximal dilation variable quantity of stage clip.
The utility model compared with prior art, its beneficial effect is:
1, overall structure advantages of simple, it is quick to make the assembling facility;
2, the location is precisely correct, and is practical reliable, reduces unnecessary economic loss.
In order to understand the utility model more clearly, set forth embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present utility model.
Fig. 3 is the structure sectional view of Fig. 2.
Fig. 4 is the structural representation of positioning pin rod among Fig. 3.
Embodiment
Shown in Fig. 2～4, novel locating stud described in the utility model, it comprises :-setting sleeve 1, to fixedly connected with cubing, its inside is provided with runs through the holding cavity 11 that is " protruding " type structure at two end part up and down;-positioning pin rod 2, activity are installed in the holding cavity 11 of setting sleeve 1 and stretch out from setting sleeve 1 upper end portion at its top;-stage clip 3 is built in the holding cavity 11 of setting sleeve 1, its two end part respectively with the bottom and the stage clip plug screw 31 contact contact matching of positioning pin rod 2.Further, described positioning pin rod 2 includes guide portion 21, positioning part 22 and slide part 23 in regular turn, wherein, guide portion 21 and slide part 23 cylindrical structures, positioning part 22 is conical structure, thereby adapts to the positioning requirements of the positioning hole in different apertures.Preferably, the length of described positioning part 22 is less than the maximal dilation variable quantity of stage clip.
Working principle of the present utility model is as described below: the workpiece positioning hole enters positioning pin rod 2 and passes guide portion 21 and arrives positioning part 22 under the leading role of the guide portion 21 of positioning pin rod 2, when just beginning, positioning hole slowly moves down, in this process, positioning hole moves downward and positioning pin rod 2 is motionless, after positioning hole moves to positioning part 22 secure fit with positioning pin rod 2, positioning hole moves downward and arrives always the top of setting sleeve 1 with positioning pin rod 2 compression press springs 3, this moment workpiece the support at setting sleeve 1 top with stop stop motion down, positioning hole is positioned.
In addition, because the external diameter of positioning pin rod is littler than the internal diameter of setting sleeve, thereby, locating stud can have moving of certain space, like this, as long as we set positioning pin rod external diameter and rational difference of setting sleeve internal diameter according to the Tolerance of Degree of position between each hole of product in design process, that a part of product that meets maximum material principle, on the irremovable cubing of positioning pin rod, can interfere, and on the mobile cubing of positioning pin rod, just can not interfere, like this, that a part of product that meets maximum material principle will be judged to acceptable product, thereby has reduced unnecessary loss.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
