Abstract
The utility model relates to an elastic diamond-shaped locating pin structure, and the elastic diamond-shaped location pin structure comprises a diamond-shaped pin body, arc planes attached to locating holes are arranged on the left and the right side of the diamond-shaped locating pin body. The middle portions of the two arc planes are respectively provided with an axial convex groove, and the axial convex groove divides the two arc planes respectively into a first arc plane and a second arc plane. An elastic groove I and an elastic grooveare arranged respectively between the first arc plane and the diamond-shaped pin body and the second arc plane and the diamond-shaped pin body. Each elastic grove I I is communicated with the axial convex groove, and each elastic groove I is communicated with the side planes of the front or back of the diamond-shaped pin body. The elastic diamond-shaped locating pin structure has the advantages that adopting elastic diamond-shaped pin with elastic grooves, arc planes on two sides of the diamond-shaped locating pin structure can be transformed elastically, the dimensional accuracy requirement of the workpiece hole is eliminated, gapless locating can be achieved, the positioning accuracy is high, and the diamond-shaped locating pin structure is elastic, wear-resisting, and prolongs the service life of a diamond-shaped pin.
Description
Technical field
The utility model relates to a kind of elasticity rhombus locating pin structure.
Background technique
Common rhombus locating stud is high to the dimension precision requirement of workpiece hole, and is big with workpiece hole surface of contact gap, the location inaccuracy, and working life is short.
Summary of the invention
The purpose of the utility model is exactly the deficiency in the background technique, and a kind of elasticity rhombus locating pin structure is provided.
For achieving the above object; The utility model adopts following technological scheme: elasticity rhombus locating pin structure; Comprise rhombus pin main body, this rhombus pin main body left and right sides is provided with the arc surface that cooperates with positioning hole, and arc surface middle part in both sides is respectively equipped with axial notch; This axial notch is separated into first arc surface, second arc surface with the arc surface of both sides respectively; Be respectively equipped with elastic groove I and elastic groove II between first arc surface, second arc surface and the rhombus pin main body, each elastic groove I all communicates with axial notch, and each elastic groove II all communicates with the side of rhombus pin main body front side or rear side.
For a kind of optimization of the utility model, end, said rhombus pin main body upper end is provided with is convenient to the chamfering that rhombus pin main body imports positioning hole.
The utility model is compared with background technique, adopts the elasticity rhombus locating stud that has elastic groove, the arc surface elastically deformable of its both sides; Reduced the dimension precision requirement to workpiece hole, can realize not having the location, gap, Location accuracy is high; Flexible, wear-resisting, prolonged working life of rhombus pin.

Fig. 1 is that the master of elasticity rhombus locating pin structure looks schematic representation.
Fig. 2 is an elasticity rhombus locating pin structure schematic top plan view.
Fig. 3 is the schematic cross-section of former rhombus locating stud.
Embodiment
Embodiment 1: with reference to Fig. 1 and 2.A kind of elasticity rhombus locating pin structure; Comprise rhombus pin main body 1; This rhombus pin main body 1 left and right sides is provided with the arc surface 1b that cooperates with positioning hole; Arc surface 1b middle part in both sides is respectively equipped with axial notch 1a, and this axial notch 1a is separated into the first arc surface 1b1, the second arc surface 1b2 with the arc surface 1b of both sides respectively, is respectively equipped with elastic groove I 1d and elastic groove II 1c between the first arc surface 1b1, the second arc surface 1b2 and the rhombus pin main body 1; Each elastic groove I 1d all communicates with axial notch 1a, and each elastic groove II 1b all communicates with the side 1f of rhombus pin main body 1 front side or rear side.End, said rhombus pin main body 1 upper end is provided with is convenient to the chamfering 1e that rhombus pin main body 1 imports positioning hole.
Chamfer 1e play the guiding role on the described elasticity rhombus locating stud; Have elastic groove I 1d and II 1c all around, all around elastically deformable reduces the dimension precision requirement to workpiece hole; Compare the mode of common rhombus locating stud with two arc surface contact workpieces surface; Two arc surface 1b of elasticity rhombus locating stud are divided into four arc surfaces by axial notch 1a, and the location workpiece is more accurate, and the rhombus locating stud form and the workpiece hole surface of contact that have elastic groove can realize not having the location, gap.
What need understand is: though present embodiment is to the utility model detailed explanation of contrasting; But these explanations; It is simple declaration to the utility model; Rather than to the restriction of the utility model, any innovation and creation that do not exceed in the utility model connotation all fall in the protection domain of the utility model.
Claims (2)
