3, alignment pin 8 must be unified sleeve 7, bearing 92 by cover, and the side gets accurate start, yet this structure is very complicated, and it is comparatively complicated to make this sleeve 7, and has generation wearing and tearing in the future the problem in gap to occur.
4, it is to be installed on fixing board fixed leg 1, the trapped orbit 2, except can left and rightly transposing, can not forward and backward and angle positioning, and be not easy to adapt to the position of different size circuit board.
The purpose of this utility model is to provide a kind of coaxial positioning apparatus of screen printer, can guarantee the location precision of circuit board, and can adjust the position location of circuit board as required, to adapt to the circuit board of different size.
The technical solution of the utility model provides a kind of coaxial positioning apparatus of screen printer, comprises the seat of cranking arm, and the seat of cranking arm connects a holder, is provided with the containing hole of device pneumatic cylinder in holder; It is characterized in that: a pneumatic cylinder is provided with the linear slide block that is combined into one with it, and its expansion link connects this linear slide block, and a location key seat is provided with alignment pin and links into an integrated entity with linear slide block; The expansion link of another pneumatic cylinder is connected with a linked block, and this linked block one end is provided with auxiliary pressing block, and auxiliary pressing block is provided with the slide opening that runs through, this slide opening and this alignment pin fit, and the slide opening and the alignment pin that form auxiliary pressing block are positioned on the same axis.
The coaxial positioning apparatus of described screen printer is characterized in that: the linked block of this auxiliary pressing block, be provided with the guide rod that pins down that fuses, and this pins down perforation that guide rod passes holder and forms and to be slidingly matched.
Effect of the present utility model is:
1. make auxiliary pressing block and alignment pin fit, form coaxial compacting, and must be when alignment pin is smoked, circuit board is lifted up on not understanding, and keeps location precision.2. auxiliary pressing block is provided with two and pins down guide rod, and can take precautions against revolving force, make auxiliary pressing block without spin masterpiece be used for circuit board, to obtain preferred positioning precision.3. alignment pin directly is connected with the linear slide block in pneumatic cylinder, but simplified construction and guarantee preferable accurate straight line start.4. whole positioner is crank arm seat, the holder that is installed on adjustable angle, adapts to the location of diverse location needs.
For effect of the present utility model is understood fully, the conjunction with figs. illustrated embodiment is described in more detail in the back now:
Being described as follows of accompanying drawing drawing:
Figure 1A is the overall appearance figure of traditional type structure, and Figure 1B is the schematic diagram that the structure of Figure 1A is analysed and observe and caused circuit board to lift up.
Fig. 2 is the utility model overall appearance figure.
Fig. 3 is the utility model three-dimensional exploded view.
Fig. 4 A is the utility model side view, and Fig. 4 B is the utility model front plan view.
Fig. 5 is the schematic diagram of the coaxial throttle circuit plate of the utility model.
See also Fig. 2,3,4, the utility model is to be provided with containing hole in a holder 11 of cranking arm seat 10, and can install pneumatic cylinder 20,30; It is characterized in that: a pneumatic cylinder 20 is provided with the linear slide block 22 of one, but its expansion link 21 interlock linear slide blocks 22, one location key seat 23 is provided with alignment pin 24 and is set as the one interlock with linear slide block 22, the expansion link 31 of another pneumatic cylinder 30 is connected with a linked block 33, these linked block 33 1 ends are provided with auxiliary pressing block 34, auxiliary pressing block 34 is provided with the slide opening 35 that runs through, and just can with alignment pin 24 fits, form the dead in line of slide opening 35 with the alignment pin 34 of auxiliary pressing block 34, auxiliary pressing block and the start up and down according to the control of pneumatic cylinder 30 separately, again, the linked block 33 of auxiliary pressing block 34, what be provided with one pins down guide rod 32, the perforation 13 that it passes holder 11, and pining down guide rod 32 can slide up and down in perforation 13;
