Summary of the invention
Technical problem to be solved by this invention is, a kind of limit accuracy height, simple in structure, easy to adjust, the test solder reflow sample position limiter that can satisfy various joint samples commonly used and the spacing requirement of components and parts Reflow Soldering are provided.
The technical solution adopted in the present invention is: a kind of solder reflow sample position limiter includes and is used to be provided with by the framework of weldering sample, is used for a plurality of feeding bolt and lock nuts and chock to the sample location; Described framework is a rectangular frame structure, and the framework inner space is placed limited sample, is formed with corresponding perforation screwed hole along in-plane respectively on the frame of per two symmetries of formation framework; The perforation screwed hole of described feeding bolt-through frame withstands on the sample and by locking nut locks; Described chock is filled in the gap of sample.
Described framework inner space is criss-cross opening.
One end of described feeding bolt is formed with nut, and the termination of the other end is smooth cylinder, is formed with external screw thread between nut and smooth cylinder.
Also be provided with the end and be formed with adjusting slider that connects screwed hole and the adjusting bolt that runs through the perforation screwed hole on the adjusting slider, and the adjusting nut that is used to adjust and lock adjusting bolt and adjusting slider, described adjusting bolt is positioned at the top of framework, describedly is enclosed within the adjusting by adjusting nut of the adjusting slider regulated on the bolt and is stuck between the frame of sample and the framework parallel with sample.
Be formed with the perforation screwed hole more than 2 or 2 on two long margin frames of described rectangular frame respectively.
Be formed with the perforation screwed hole more than 1 or 1 on two minor face frames of described rectangular frame respectively.
Solder reflow sample position limiter of the present invention, limit accuracy height, simple in structure and be easy to regulate, degree of regulation can reach 0.02mm, can effectively eliminate in the welding process owing to the spacing inaccurate or unstable sample that produces is offset defectives such as serious, do not need to change existing welding procedure, can satisfy multiple joint sample and the spacing requirement of components and parts Reflow Soldering commonly used.

The specific embodiment
Below in conjunction with embodiment and accompanying drawing solder reflow sample position limiter of the present invention is made a detailed description.
As Fig. 1, Fig. 3～shown in Figure 7, solder reflow sample position limiter of the present invention includes and is used to place by the framework 1 of weldering sample 6, is used for to sample 6 spacing a plurality of feeding bolts 2 and locking nut 5 and chock 3; Described framework 1 is a rectangular frame structure, space at framework 1 inboard cross opening is provided with the sample 6 that is positioned, be formed with corresponding perforation screwed hole 8 along in-plane respectively on the frame of per two symmetries of formation framework 1, wherein, be formed with the perforation screwed hole 8 more than 2 or 2 on two long margin frames of described rectangular frame 1 respectively, be formed with the perforation screwed hole 8 more than 1 or 1 on two minor face frames of described rectangular frame 1 respectively; The perforation screwed hole 8 that described feeding bolt 2 runs through frame withstands on the sample 6 also by locking nut 5 lockings; Described chock 3 is filled in the gap of sample 6, chock 3 decapacitation accurately guarantee between sample outside the relative gap, can also effectively stop in the welding process scolder to spill into gap location and produce defectives such as incompletely filling, the shape of chock and size should be done the adaptability change with specimen types and change in size.
As shown in Figure 8, an end of described feeding bolt 2 is formed with nut 9, and the termination of the other end is smooth cylinder 10, and the cylinder outer face is obvious to the position-limiting action of sample.Between nut 9 and smooth cylinder 10, be formed with external screw thread 11.
