Description
Technical field
The utility model belongs to electronics manufacture field, and patent is related to a kind of quick optocoupler pipe leg leg scissors tooling.
Background technology
In recent years, as electronic product is light, small, thin and multifunction requirement is higher and higher, this results in the knot of product
Structure size is less and less, and it is less and less that inside leaves the space that printed circuit board assembly is assembled for, on printed circuit board
Placing components inserting, with regard to severely limited, otherwise can interfere to the pipe leg height after printed board, product is caused to occur
Fault.In current application, dual inline type photoelectrical coupler pipe leg length that enterprise largely uses often for 3.81mm with
On, and printed board thickness is generally 1.5mm~2.0mm, after optocoupler inserting, pipe leg end to soldering of printed boards face height is
1.81mm~2.31mm is unsatisfactory for the requirement that certain Product Assembly gaps are less than 1.5mm.Even if certain products have enough assemblings
Space, but the optocoupler pipe leg material is partially soft, and pipe leg height is more than easily bending after 1.5mm, causes the interference between device pipe leg.
It, can not due to there is no special tooling, optocoupler to be cut short optocoupler pipe leg, but due to manual operation with flat-nose pliers after inserting
Height after control pipe leg is cut, so as to influence to insert and weld.So the method taken at present in current techniques is：Optocoupler is welding
After connecing, leg scissors processing is carried out to optocoupler with side-cutting pliers, then need reviewer with vernier caliper to optocoupler pipe leg height one by one
It measures and checks.Artificial leg scissors can not ensure pipe leg high consistency, so that reviewer is needed to measure inspection one by one to pipe leg,
It increases the workload of reviewer and easily causes work fatigue and cause detection leakage phenomenon.In order to reduce working hour, efficiency is improved, is protected
Optocoupler pipe leg high consistency is demonstrate,proved, the commercial plant (hereinafter referred to as tooling) of design specialized leg scissors is needed to carry out machinery to optocoupler
Leg scissors.
Utility model content
The purpose of this utility model is for the inconsistent deficiency of the manual height of leg scissors one by one present in current techniques, is provided
A kind of quick optocoupler pipe leg leg scissors tooling.The tooling integrally positions leg scissors by the pipe leg to optocoupler and designs (or use), can be with
It realizes highly consistent and easy to operate after optocoupler pipe leg leg scissors.This tooling is suitable for other as long as with changing locating piece
Component leg scissors.
The technical solution of the utility model is：
A kind of quick optocoupler pipe leg leg scissors device, composition include pressing plate, screw, sword bar, connector sleeve and locating piece；
Wherein, pressing plate is circular piece ring plate；
The lower part of the locating piece is rectangular blocks, and there are one cylinders for upper end fixation, and the cross section of rectangular blocks is just
Rectangular, the diameter of the length of side and cylinder is just as and being coaxially distributed；The cavity of up/down perforation is provided with inside locating piece, cavity horizontal stroke
Section is square, and guide rail is provided with from top to bottom among each side wall of cavity；It is threaded outside locating piece top cylinder,
Four sides of lower rectangular block have regularly arranged through-hole, wherein, the size of the through-hole in three faces, spacing respectively with
The leg of current common 6 needle, 8 needles and 16 needle optocoupler pipes matches；
Connector sleeve is cylindrical structure, and middle part is provided with circular hole, and madial wall is threaded and phase outside locating piece top cylinder
Match；
The material of sword bar is high-speed steel, and top is round bar, and lower part is square body structure, the length of side and locating piece of square
The length of side matching of internal cavity；Top round bar center is provided with threaded hole, and threaded hole is connected with screw, and lower part square end face concaves
It falls into, edge puts the first edge on a knife or a pair of scissors；Side vertical is provided with guide-track groove and matches with the guide rail inside locating piece；The square structure of sword bar lower part is inserted
Enter in the cavity in locating piece, the round bar on top passes through connector sleeve, is connected by screw with pressing plate；
The height of the positioning rectangular blocks in the block is 35mm, length of side 20mm；The height of cylinder is 15mm；
The height of the sword bar lower part square is 10mm, and the height of top round bar is 40mm.
The beneficial effects of the utility model are：
Since optocoupler pipe leg material is partially soft so institute's shearing force is small, the present apparatus can ensure remaining pipe in shear history
Leg verticality.The utility model is sheared by the whole optocoupler pipe leg high unity that positions, without using flat-nose pliers, to optocoupler pipe leg
Height is being measured one by one to shearing one by one, without the expensive pipe leg special equipment of purchase by programming leg scissors again, so as to
The quick cheap optocoupler pipe leg that reaches is sheared.
