Bad, defect is obvious.
Utility model content
The technical problems to be solved in the utility model is to provide one kind and is prevented effectively from product and is stuck to be broken off with pin, together
When ensure product orientation required precision pin location structure.
In order to solve the above-mentioned technical problem, the utility model is adopted the following technical scheme that：
A kind of pin location structure, including location-plate, the first alignment pin and the second alignment pin that are arranged at location-plate, it is described
Second alignment pin includes cylindrical body, and cylindrical body is provided with construction section and positioning section, and positioning section, which is provided with from disconnected be axially facing, to be prolonged
Some empty avoiding planes stretched, adjacent empty avoiding plane connecting cylinder cambered surface；First alignment pin includes being used to be installed in location-plate
Canned paragraph, the cooperation section for positioning product and with coordinating the taper empty avoiding that be connected of section section, when being positioned to product, cylinder
The surface of cambered surface and cooperation section is contacted with product.
Wherein, the empty avoiding plane is provided with four, and four empty avoiding planar circumferentials are uniformly distributed in positioning section.
It is preferred that, it is described to coordinate the length a of section to be 1.3 to 1.8mm.
It is preferred that, the unilateral gap of the cooperation section and positioning hole is 0.04 to 0.08mm.
It is preferred that, the taper c of the taper empty avoiding section is 1 to 3 degree.
It is preferred that, the end face of the taper empty avoiding section is provided with rounding, and rounding radii R is equal to 0.5mm.
The beneficial effects of the utility model：
During practical application, the canned paragraph of the construction section of the first alignment pin and the second alignment pin is arranged on location-plate；To production
When product are positioned, cylinder cambered surface is contacted with the positioning hole of product, and empty avoiding plane is not contacted with the positioning hole of product, product with
There is the space of empty avoiding between empty avoiding plane, the contact surface of the positioning hole of the second alignment pin and product is reduced；The positioning hole of product
With coordinating section and taper empty avoiding section to be assembled, only section is coordinated to coordinate with positioning hole, taper empty avoiding section and the hole wall of positioning hole
It is discontiguous, there is empty avoiding gap therebetween.The positioning of first alignment pin and the second alignment pin of the present utility model with product
Hole contact area is small so that product is picked and placeed conveniently, accurate positioning, effectively avoid product be stuck be broken off with pin it is existing
As.
Brief description of the drawings
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is the structural representation of the second alignment pin described in the utility model.
Fig. 3 is the structural representation of the first alignment pin described in the utility model.
Fig. 4 is the local cross-sectional view of the utility model.
Embodiment
For the ease of the understanding of those skilled in the art, further is made to the utility model with reference to embodiment and accompanying drawing
Explanation, the content that embodiment is referred to not to it is of the present utility model limit.
As shown in Figures 1 to 4, a kind of pin location structure, including location-plate 1, the first alignment pin for being arranged at location-plate 1
2 and second alignment pin 3, second alignment pin 3 includes cylindrical body, and cylindrical body is provided with construction section 31 and positioning section 32,
Positioning section 32 is provided with from section to axially extending some empty avoiding planes 33, the adjacent connecting cylinder cambered surface 34 of empty avoiding plane 33；Institute
Stating the first alignment pin 2 is included for the canned paragraph 21 for being installed in location-plate 1, the cooperation section 22 for positioning product and with coordinating section
The taper empty avoiding section 23 of 22 connections, when being positioned to product, the surface of cylinder cambered surface 34 and cooperation section 22 is contacted with product.
During practical application, the canned paragraph 21 of the alignment pin 3 of construction section 31 and second of the first alignment pin 2 is arranged on location-plate 1
On；When being positioned to product 01, cylinder cambered surface 34 is contacted with the positioning hole of product 01, and empty avoiding plane 33 and product 01 are determined
Position hole is not contacted, and has the space 02 of empty avoiding between product 01 and empty avoiding plane 33, and the second alignment pin 3 of reduction is determined with product 04
The contact surface in position hole；The positioning hole of product 01 only coordinates section 22 with determining with coordinating section 22 and taper empty avoiding section 23 to be assembled
Position hole coordinates, and taper empty avoiding section 23 and the hole wall of positioning hole are discontiguous, there is empty avoiding gap therebetween.Of the present utility model
The positioning hole contact area of one alignment pin 2 and the second alignment pin 3 with product 01 is small so that product 01 is picked and placeed conveniently, positioning accurate
Standard, effectively avoids product and is stuck and be broken off phenomenon with pin.
