Abstract
The invention discloses a nut press fitting fixture which comprises a support, an air cylinder, a press plate, a pressure head, a carrier plate and a spacing guiding device, wherein the spacing guiding device comprises a spring, as well as a linear bearing and a positioning guiding pillar which are matched, and the top end of the positioning guiding pillar is provided with a nut sleeving structure; one ends of the carrier plate, the linear bearing and the spring are fixed together with the support, and the other end of the spring is fixed together with the bottom end of the positioning guiding pillar; and when the spring is in a natural state, the top end of the positioning guiding pillar passes through and protrudes out of nut mounting holes of the carrier plate and a PCB (printed circuit board), a cylinder body of the air cylinder is fixed together with the support, the output shaft of the air cylinder vertically faces to the carrier plate and is fixed together with the press plate, and a pressure head is fixed on one side, facing to the carrier plate, of the press plate. The nut press fitting fixture provided by the invention can guarantee the high accordance of nut press fitting height, has less possibility of damaging the PCB, meanwhile, and can be used for performing press fitting of multiple nuts on the PCB once; and the air cylinder is adopted as a power source, the labor cost is saved, and meanwhile the yield and the production efficiency are improved.
Description
Technical field
The utility model relates to pcb board endoporus self-clinching nut technique, particularly relates to a kind of nut press mounting tool.
Background technology
Now, pcb board endoporus self-clinching nut is adopted usually and beats press mode by hand, owing to can only hold by operating personnel are subjective by rule of thumb the dynamics of beaing and the degree of depth, often cause nut compression distance inadequate, or damage the situation of pcb board, and manual beaing once can only be pressed into a nut, and efficiency is low, cost is high, can not meet volume production demand.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of nut press mounting tool of mechanization, avoids the damage of pcb board, enhance productivity while ensureing the compression distance of nut.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Nut press mounting tool, comprise support, upper module and lower module, described upper module comprises cylinder, pressing plate and pressure head, described lower module comprises the support plate and limit guiding device of placing pcb board, described limit guiding device comprises spring, supporting linear bearing and orientation direction post, and linear bearing is sleeved on the outside of orientation direction post, the top of orientation direction post is provided with nut sleeve assembling structure; One end and the support of described support plate, linear bearing and spring are fixed, the other end of spring with fix with the bottom of orientation direction post, during spring nature, the top of orientation direction post is passed and is protruded the nut installing hole of support plate and pcb board; Cylinder body and the support of described cylinder are fixed, and its output shaft vertically support plate fixing with pressing plate, pressure head is fixed on the side of pressing plate towards support plate.
During use, be first placed on support plate by pcb board, orientation direction post, through the nut installing hole on pcb board, plays the effect of location to pcb board; Again by nut sleeve on the nut sleeve assembling structure on positioning guide column top; Start cylinder, the output shaft of cylinder promotes pressing plate band dynamic head and moves towards pcb board, after pushing down nut, drives nut to move together and is pressed into by nut in the nut installing hole of pcb board to pressure head, and Compress Spring; When nut is pressed into place, spring is in impaction state, and the further movement of restriction orientation direction post, avoids damaging pcb board by pressure.
Preferably, this pressing mounting tool also comprises rectilinear motion attitude reference device, and described rectilinear motion attitude reference device comprises leading axle and is arranged on slide opening on pressing plate, and described leading axle to be fixed on support perpendicular to support plate and to penetrate in slide opening.High-head kinematic accuracy can be put forward by rectilinear motion attitude reference device, avoid it does not push down nut completely and cause nut to produce oblique press-in, damage pcb board.
Preferably, described support for being 45 steel matter, and is provided with chromium coating on surface.
Preferably, described support plate is for flooding glass-fiber-plate material; Owing to being interference fit between nut and pcb board, because pcb board strength ratio nut is little in process of press in, therefore the lifting surface area of pcb board wants large, so increase at pcb board reverse side the support plate that a piece floods glass-fiber-plate material, disperse stress point, strengthen lifting surface area, such pcb board is just not easy to have damaged.
Beneficial effect: the nut press mounting tool that the utility model provides, can ensure that nut press mounting height is consistent, and not fragile pcb board, once can press-fit the multiple nuts on a slice pcb board simultaneously; Adopt cylinder as power source, can cost of labor be saved, improve yield and production efficiency simultaneously.
