Embodiment
Below in conjunction with drawings and Examples, a kind of press-mounting mechanism for converter valve thyristor of the present invention is described in detail.
As Figure 1-5, a kind of press-mounting mechanism for converter valve thyristor of the present invention comprises that a fluid head 1, a thyristor press-fit integrated package and an assembly platform.This assembly platform comprises desk 3, press-fits base 5, gravity block 6, press-fit pin 4, pin 7, transverse slat 8, upper transfer block 9 and lower transfer block 10.The upper surface of the desk 3 of assembly platform is smooth smooth, what its right-hand member was being placed a cubic structure press-fits base 5, this press-fits together with smooth smooth, the lower surface of the upper surface of base 5 fits tightly with the upper surface of desk 3, and press-fits base 5 and be connected with the desk 3 of assembly platform with lower transfer block 10 by the upper transfer block 9 of " door hinge " structure.On this, transfer block 9 is fixed by screws in the left side wall lower end middle part that press-fits base, two lower transfer blocks 10 both sides in upper transfer block 9, and be flexibly connected with upper transfer block 9 by a pin 7, two lower transfer blocks 10 are fixed by screws on desk 3.By relatively rotating between pin 7 and upper transfer block 9, lower transfer block 10, just realize the rotating function of pin rotating mechanism.Vertically fix two on the top of left side wall that press-fits base 5 and press-fited pin 4.This press-fits pin 4 perpendicular to the upper surface that press-fits base 5, and the width that the distance between pin press-fits integrated unit than radiator and thyristor is slightly large, thyristor press-fits integrated (TCA), and unit can just be vertically placed on press-fits between pin 4, connects root simultaneously and press-fits and on pin, also equally spaced fixed two transverse slats 8.In the time that placement thyristor press-fits integrated package and radiator, can locate easily like this, prevent from, press-fiting the continuous module position of adjusting in process, greatly having saved the time, improve efficiency.On the right side wall that press-fits base, be provided with a smooth smooth gravity block 6 of lower surface, the size of this gravity block 6 and weight are all through reasonably design, for this assembly platform of balance, prevent from, press-fiting in process because the problem that base rotates to the left appears press-fiting in left and right unbalance stress, having guaranteed like this stability and the fail safe of operating process.Be a fluid head matching with it 1 on the top of whole assembly platform, this fluid head 1 is for press-fiting the assembly such as thyristor and radiator placing.
The process that press-fits that thyristor is press-fited to integrated package 2 is below done simple introduction:
(1) thyristor being press-fited to integrated (TCA) unit housing is positioned over and press-fits on base 5;
(2) parts such as radiator, thyristor are alternately placed on to thyristor and press-fit in integrated (TCA) unit housing, in put procedure, radiator will be close to and press-fit pin 4.Radiator is to press-fit pin 4 as positioning datum, and thyristor is vertically piled up with assurance radiator, thyristor take radiator as positioning datum;
(3) all parts that thyristor press-fited to integrated package 2 are assembled in thyristor by fluid head 1 and press-fit on integrated package 2 after having assembled, and by hydraulic pressurization, and maintain pressure certain hour, complete thyristor and press-fit integrated package and press-fit;
(4) assembly platform and thyristor are press-fited together with integrated package 2 and fell, after setting level, take thyristor away and press-fit integrated package 2.Figure 4 shows that platform fell after state.
Fig. 6 is that the thyristor of a kind of press-mounting mechanism for converter valve thyristor of the present invention press-fits integrated structural representation, and thyristor press-fits, and integrated (TCA) comprises thyristor, thyristor radiator, metal end plate, insulation board and busbar; Be inlaid with the dish spring in compressive state in metal end plate inside; Together with dish spring is fitted in thyristor closely with thyristor radiator, the stiction producing by pressure assembling force and pressure assembling force, thyristor press-fits entirety of integrated formation; The effect of busbar is On current; Metal end plate and insulation board jointly form thyristor and press-fit integrated outside framework.
A kind of press-mounting mechanism for converter valve thyristor of the present invention, on the basis take hydraulic pressure as power source, utilizes pin rotating mechanism to design movable, rotatable assembly platform.Press-fiting in process, operating personnel's thyristor that can fall easily press-fits integrated unit 2, has so both reduced operation easier, can raise the efficiency again.Due to this press-loading device specialized designs thyristor press-fit integrated pin, the location that press-fits integrated package for radiator and thyristor provides benchmark, has guaranteed that radiator and thyristor press-fit the position consistency of integrated package.The trouble of having avoided so constantly adjusting module position before press-fiting, has improved production efficiency.The right side wall that the thyristor of this press-loading device press-fits integrated base is provided with a gravity block, and this gravity block is the center of gravity of equilibrium pressure mounting mechanism well, prevents from the time vertically press-fiting, occurring press-mounting platform rotary moveable, has guaranteed to press-fit the safety of process.On the whole, a kind of press-mounting mechanism for converter valve thyristor of the present invention is simple in structure, easy to operate, safe and reliable, time saving and energy saving, can perform well in press-fiting of converter valve thyristor.
Finally should be noted that: only illustrate that in conjunction with above-described embodiment technical scheme of the present invention is not intended to limit.Those of ordinary skill in the field are to be understood that: those skilled in the art can modify or be equal to replacement the specific embodiment of the present invention, but among the claim protection range that these modifications or change are all awaited the reply in application.
