Abstract

The invention discloses a non-isometrical waisted circular cylindrical pin, which adopts the technical scheme that an imbedding section (31) and a connecting section (33) are cylindrical in appearance; the middle part of a waisted circular section (32) is a small section of concave waisted circle, and a conical surface is processed at the tail part of the waisted circle; a female part (1) is connected with the imbedding section (31) in a transition fit way, and a matched part (2) is connected with the connecting section (33) in a clearance fit way; the groove width of the waisted circular section (32) of the waisted circular cylindrical pin (3) is 2.5-3 mm; the diameter theta D of the waisted circle at the middle part of the waisted circular section (32) is 4-10 mm; and the excircle diameters theta D of the imbedding section (31) and the connecting section (33) are 6-12 mm. The non-isometrical waisted circular cylindrical pin can realize the reliable positioning function, and can be dismounted without being damaged by a fixture through utilizing the conical surface at the middle section part at the same time.

Description

A kind of non-isometrical oval type straight pin
Technical field
The present invention relates to mechanical manufacturing field, relate in particular to a kind of non-isometrical oval type straight pin.
Background technique
Any engineering goods will be brought into play its complete function and meet the demands of production and living, and are not to constitute and can reach by single component.So its location, connection or cooperation are very necessary and general between the different parts of formation engineering goods.And for accurate day by day engineering goods, be the content that engineering goods must take in and pay attention in links such as design, processing, assembling as accurate " location " between the different parts of its system's formation and assurance reliably working.The present invention's " a kind of non-isometrical oval type straight pin " namely is for satisfying a kind of structure of locating function between the part, and it is a part of forming complete engineering goods, also is simultaneously a kind of tie that connects between the adjacent parts.
Summary of the invention
The object of the invention is to replace traditional straight cylinder pin with oval type straight pin, and a kind of non-isometrical oval type straight pin is provided.The present invention both can realize reliable locating function, can utilize the conical surface of its intermediate section part with anchor clamps pin to be realized the not damaged dismounting simultaneously.
Technological scheme of the present invention is, a kind of non-isometrical oval type straight pin, comprise: female part 1, kit 2, oval type straight pin 3, described oval type straight pin 3 comprises buried section 31, oval section 32 and linkage section 33 again, described buried section 31 and linkage section 33 profiles are cylindrical body; Oval section 32 intermediate portions are a bit of recessed oval, and process the conical surface at afterbody; Female part 1 is connected with buried section 31 transition fit, and kit 2 is connected with linkage section 33 Spielpassung.
Oval section 32 groove widths of described oval type straight pin 3 are 2.5~3mm, and oval section 32 intermediate portion oval D are 4~10mm.
The outside diameter d of described buried section 31 and linkage section 33 is 6~12mm.
The invention has the beneficial effects as follows, be hierarchic structure by improving traditional straight cylinder pin, and by function with need segmentation processing, both satisfied locating function, can conveniently realize the not damaged dismounting of pin again, also reduce the processing technology requirement simultaneously, because only need fine finishing be carried out on the surface, buried section.According to the size of workpiece and the needs of different use occasions, the present invention also can form series product, the column criterionization of going forward side by side.
Description of drawings
Fig. 1 is mounting structure generalized section of the present invention,
Fig. 2 is a kind of plan view of non-isometrical oval type straight pin.
1. female parts among the figure, 2. kit, 3. oval type straight pin, 31. buried sections, 32. oval sections, 33. linkage sections.
Embodiment
As shown in Figure 1, when engineering goods are assembled, earlier the buried section 31 of oval type straight pin 3 is imbedded in female part 1 until imbedding end 31 fully towards female part 1 and the pin-and-hole of vertically packing into, it cooperates is H7/m6.Then, kit 2 vertically is contained in along pin-and-hole on the linkage section 33 of oval type straight pin 3, it cooperates is E8/m6 again.When carrying out the engineering goods decomposition, earlier kit 2 is unclamped and take off, if oval type straight pin 3 also need be taken off, then clamp oval section 32 outer conical surface of oval type straight pin 3 with pliers or other jigs from female part 1, outwards firmly can take off smoothly, and reuse.
