The tin furnace lifting mechanism as the following advantages of being reasonable in design, simple in structure, high in automation degree, stable in running, adjustable in mechanical height, capable of flexibly compensating crest height, low in production cost and convenient to popularize and use.
Description
Technical field
The present invention relates to a kind of elevating mechanism, be specifically related to a kind of selective crest welder tin stove elevating mechanism.
Background technology
Double-sided PCB is generally welded by artificial or wave-soldering, but these two kinds of methods have increased cost, have reduced speed of production.Therefore, a lot of companies use selective Wave soldering instead.But in the process of using selective Wave soldering welding, crest is too high or too lowly all can have a strong impact on welding quality, can go out such as: insufficient solder connection and solder joint draw the series of problems such as point.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of selective crest welder tin stove elevating mechanism is provided, it is reasonable in design, and is simple in structure, automaticity is high, and is stable, and mechanism height can be regulated, but the flexible compensation crest height, production cost is low, is convenient to promote the use of.
for achieving the above object, the technical solution used in the present invention is: a kind of selective crest welder tin stove elevating mechanism, it is characterized in that: comprise base weld assembly and the motor that is arranged on base weld assembly downside, described base weld assembly upper interior is slidably fitted with the lifting platform weld assembly, described lifting platform weld assembly inboard is installed with big nut, described big nut inboard is equipped with large screw rod by screw thread, described large screw rod bottom is rotatably installed in base weld assembly upper inside by bearing block and bearing, described large screw rod is connected with motor output shaft, described base weld assembly top is provided with travel switch, described lifting platform weld assembly tip platform one side is provided with the stroke limit piece.
Described lifting platform weld assembly and base weld assembly cross section are rectangle.
Described motor is stepper motor.
Described bearing is two-direction thrust bearing.
The present invention compared with prior art has the following advantages:
(1) this selective crest welder tin stove elevating mechanism design is very reasonable, and structure is relatively simple, uses easy and simple to handle.
(2) operation characteristic of crest welder tin stove elevating mechanism selective according to this, work out corresponding control program, and automaticity is very high, being used in conjunction with of big nut and large screw rod, can realize the steady lifting of tin stove.
(3) but this selective crest welder tin stove elevating mechanism height flexible modulation can facilitate the compensated wave peak heights.
(4) a lot of parts of this selective crest welder tin stove elevating mechanism all are convenient to produce, buy very much, thereby its production cost is very low, is convenient to promote the use of.
Below by drawings and Examples, the present invention is described in further detail.

The specific embodiment
A kind of selective crest welder tin stove elevating mechanism as depicted in figs. 1 and 2 comprises base weld assembly 2 and the motor 3 that is arranged on base weld assembly 2 downsides, and described motor 3 is stepper motor.Described base weld assembly 2 upper interior are slidably fitted with lifting platform weld assembly 1, described lifting platform weld assembly 1 inboard is installed with big nut 1-1, described big nut 1-1 inboard is equipped with large screw rod 6 by screw thread, big nut 1-1 and large screw rod 6 are used in conjunction with, and can make the lifting of whole mechanism steadily, reliably.Described large screw rod 6 bottoms are rotatably installed in base weld assembly 2 upper inside by bearing block 4 and bearing 5, and described bearing 5 is two-direction thrust bearing, and two-direction thrust bearing can prevent large screw rod play Shang Xia 6, guarantees large screw rod flexible rotating.Described large screw rod 6 is connected with motor 3 output shafts, and described base weld assembly 2 tops are provided with travel switch 7, and travel switch 7 can be controlled motor 3 rotatings, is unlikely to descend too low thereby control lifting platform weld assembly 1 position.Described lifting platform weld assembly 1 tip platform one side is provided with stroke limit piece 8, stroke limit piece 8 with lifting platform weld assembly 1 by threaded engagement, can the free adjustment height, the adjusting of easy of rise platform weld assembly 1 adjustable height.
As shown in Figure 2, described lifting platform weld assembly 1 and base weld assembly 2 cross sections are rectangle.
The course of work of the selective crest welder tin of the present invention stove elevating mechanism is: at first should be fixed on workbench by selective crest welder tin stove elevating mechanism, starter motor 3, motor 3 is rotated in the forward, thereby driving large screw rod 6 is rotated in the forward, large screw rod 6 drives the big nut 1-1 that is mated and moves downward, thereby lifting platform weld assembly 1 is moved downward in base weld assembly 2 inside, realize that tin stove 9 moves downward.After arrival lifting platform weld assembly 1 is encountered travel switch 7, travel switch 7 is controlled motor 3 reverse rotations, thereby drive large screw rod 6 reverse rotations, large screw rod 6 drives the big nut 1-1 that is mated and moves upward, thereby make lifting platform weld assembly 1 in base weld assembly 2 moved upward inside, realize that tin stove 9 moves upward.
The above; it is only preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every according to the technology of the present invention essence to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solution of the present invention.
