Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1, shown in 2, the utility model embodiment provides a kind of vertical flying probe machine clamp, comprise and symmetrical be arranged on upper fixture 100 on described vertical flying probe tester and lower clamp (not indicating in figure), described upper fixture 100 comprises the clamp fixing plate 110 be fixedly connected with described vertical flying probe tester, clamp fixing plate 110 pairs of pcb boards are coordinated to carry out clamping and the fixture portable plate 120 unclamped, drive described fixture portable plate 120 near or away from the connecting link 130 of described clamp fixing plate, drive the drive unit 140 of described connecting link, and the front and back pilot unit 150 be vertically installed on described clamp fixing plate 110 and described fixture portable plate 120, wherein, in described clamp fixing plate 110 activity of elongatedness direction be provided with clamp shaft 111, described connecting link 130 one end is flexibly connected with described clamp shaft 111, and the other end is flexibly connected with described fixture portable plate 120, it is movable that described drive unit 140 drives described clamp shaft 111 to prolong described clamp fixing plate 110 length direction, and drive connected connecting link 130 to move, thus the close meeting of fixture portable plate 120 realizing being flexibly connected with described connecting link 130 is away from described clamp fixing plate 110.
As shown in the connecting link force analysis figure of Fig. 3, the connecting link 130 of the utility model embodiment is positioned at the below of front and back pilot unit 150 with the position being flexibly connected point of fixture portable plate 120, see so from top to down, the fulcrum of described vertical flying probe machine clamp is in the top, during clamping pcb board, described vertical flying probe machine clamp can form the state of V-shaped, and namely the below of fixture portable plate 120 is than top closer to PCB, clamps more reliable.
In the present embodiment, described drive unit 140 is cylinder, and the output shaft (not indicating in figure) of described cylinder is fixedly connected with one end of described clamp shaft 111.
Further, the output shaft of described cylinder is provided with floating junction 141, is provided with the clamp shaft card extender 142 be fixedly connected with between described floating junction 141 with described clamp shaft 111.
All undertaken hinged by joint pin 131 respectively between described connecting link 130 one end and described clamp shaft 111 and between the other end and described fixture portable plate 120.To be fixed in described clamp fixing plate 110 due to described cylinder and to be fixedly connected with described clamp shaft 111, so clamp fixing plate 110, cylinder, clamp shaft 111 three are equivalent to an entirety, when described connecting link 130 respectively at described clamp shaft 111 and fixture portable plate 130 hinged time, air cylinder driven clamp shaft 111, can make connecting link 130 drive clamping portable plate 120 near or away from described clamp fixing plate 110.
Concrete, described connecting link as shown in Figure 3 stressed, when connecting link 130 is subject to the driving of cylinder, clamp fixing plate 110 length direction (left and right directions) is prolonged when moving in the one end be hinged with described clamp shaft 111, because the front and back pilot unit 150 being fixed with vertical with the two length direction (fore-and-aft direction) between described clamp fixing plate 110 with described fixture portable plate 120 is spacing to it, make the other end of described connecting link 130 can only prolong fore-and-aft direction to move, thus make fixture portable plate 120 also can only prolong fore-and-aft direction near or away from described clamp fixing plate 110.
In the present embodiment, when described fixture portable plate 120 presents open mode (N) with described clamp fixing plate 110, described connecting link 130 is parallel with described front and back pilot unit 150; When described fixture portable plate 120 presents clamped condition (M) with described clamp fixing plate 110, in θ angle between described connecting link 130 and described front and back pilot unit 150.Certainly, in other embodiments, also can in contrary state.
Further, described front and back pilot unit 150 comprise one end be fixed on described in be fixedly clamped on plate 110, the axis of guide 151 be arranged on described clamping portable plate 120 of other end activity.
Concrete, described clamping portable plate 120 is provided with the through hole 131 with the described axis of guide 151 adaptation.Described front and back pilot unit 150 also comprises the axis of guide mount pad 152 of the fixing described axis of guide 151, is fixedly clamped on plate 110 described in described axis of guide mount pad 152 is fixedly installed on.The described axis of guide 151 is fixed on the described axis of guide due to one end and is mounted on 152, one end activity be arranged in described through hole 131, make described clamping portable plate 120 can only prolong the described axis of guide 151 direction (fore-and-aft direction) mobile, realize the clamping of pcb board or unclamp.
Further, lead more smoothly before and after making, in described through hole 131, be provided with the linear bearing 132 with the described axis of guide 151 adaptation.
Described clamping portable plate 120 is also fixed with linear bearing mount pad 133, and described through hole 131 is arranged in described linear bearing mount pad 133, and described linear bearing 132 is arranged in described through hole 131.
Further, described clamp fixing plate 110 is provided with the left and right pilot unit 112 with described clamp shaft 111 adaptation.Described left and right pilot unit 112 comprises without oily lining (not indicating in figure) and fixing described guiding mount pad of the left and right without oily lining (not indicating in figure), is fixedly clamped on plate 110 described in what described left and right guiding mount pad was fixing be arranged at.
Further, according to varying in size of described upper fixture 100, be convenient to fixing or spacing, and facilitate the transmission of power, described connecting link 130, front and back pilot unit 150 or left and right pilot unit 112 is multiple, in the present embodiment, is two.
Further, the side that described clamp fixing plate 110 is relative with described fixture portable plate 130 is respectively arranged with has flexible fastening strip 160.
When the fastening strip 160 on fixture portable plate 120 contacts with PCB, the large distance motion of fixture portable plate 120 terminates, clamp shaft 111 can continue to keep action left, because fastening strip 160 has elasticity, the faint action of fixture portable plate 120 meeting, terminate until fastening strip 160 is out of shape, now PCB is also clamped.When fixture is opened, cylinder resets, and clamp shaft 111 moves right, and fixture returns to shown position.It is large as far as possible that elasticity due to fastening strip 160 can make rough PCB surface be in contact with it area, so holding force distribution is very even.
Further, the surface of described fastening strip 160 is provided with rough layer.There is the fastening strip of certain roughness that PCB also can be made to clamp more reliable.
Further, described fastening strip 160 is made for insulating material.In the present embodiment, for plastic cement is made, the deformation characteristic of the fastening strip 160 that plastic cement makes can also make PCB surface avoid being scraped off, and also can play the effect of insulation.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; make some equivalent alternative or obvious modification without departing from the concept of the premise utility; and performance or purposes identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
