A kind of PCB stationary fixtures of chip mounter, including fixed frame, the fixed frame splice quadrangularly by four coaming plates； Four coaming plates include the first coaming plate being oppositely arranged and the second coaming plate, and the upper surface of the first coaming plate and the second coaming plate offers Sliding groove, the notch of the sliding groove is provided with the clamp extended laterally, so that the width of the sliding groove notch is less than sliding groove Width between two side walls；It is equipped with least two fixed plates on first coaming plate and the second coaming plate, the fixation on the first coaming plate Fixed plate on plate and the second coaming plate extends towards, and the fixed plate in fixed plate and the second coaming plate on the first coaming plate extends towards The upper surface of that one end be equipped with vertically extending guide pillar, in the pluggable preset jack on PCB of the guide pillar；It is described Vertically extending through hole is further opened with fixed plate, screw is equipped with the through hole, and the screw is extend into sliding groove And can be slided in sliding groove, one end that screw is extended in sliding groove is fixed with head of screw, and the width of the head of screw is more than The width of sliding groove notch；The screw is also socketed with nut in the top of fixed plate.

Preferably, the sliding groove is provided at both ends with the locating part being fastened in sliding groove.

Preferably, the fixed plate is triangle plate shape, and width is sequentially reduced fixed plate in the direction of extension.

Preferably, two fixed plates are equipped with first coaming plate and the second coaming plate.

Preferably, the jack is located at PCB corner.

The beneficial effects of the utility model are, because the utility model is opened in the upper surface of the first coaming plate and the second coaming plate Provided with sliding groove, fixed plate can be slided in sliding groove, so as to move freely circuit board.And matching somebody with somebody by screw and nut Close, at any time can fasten fixing board card in sliding groove, and then can fixing circuit board.Therefore, the utility model only needs Tightening nut, then moving fixed plate can be such that the movement of circuit board is more convenient, more rapidly circuit board movement or fixed.

Brief description of the drawings

Fig. 1 is a kind of structural representation of the PCB stationary fixtures of the chip mounter of embodiment of the utility model；

Fig. 2 is a kind of profile of the PCB stationary fixtures of the chip mounter of embodiment of the utility model.

Embodiment

The utility model is described in further detail below by embodiment combination accompanying drawing.

A kind of PCB stationary fixtures of chip mounter, the fixture are arranged on chip mounter.As depicted in figs. 1 and 2, it includes solid Determine frame 1, the fixed frame 1 splices quadrangularly by four coaming plates, and specifically, four coaming plates are spliced into the rectangle of rule.Should Four coaming plates include the first coaming plate 11 and the second coaming plate 12 in opposite, and the first coaming plate 11 is parallel with the second coaming plate 12 to be set Put, offer sliding groove 20 in the upper surface of the first coaming plate 11 and the second coaming plate 12, the sliding groove 20 encloses along corresponding first The bearing of trend extension of the coaming plate 12 of plate 11 and second.As shown in Fig. 2 the notch 21 of the sliding groove 20 is provided with the card extended laterally Plate 22, the presence of clamp 22 make the width of the notch 21 of the sliding groove 20 be less than the width between 20 two side walls of sliding groove, It is less than the inner width of sliding groove 20, then clamp 22 can be with clamping head of screw 42.

Two fixed plates 3 are equipped with the first coaming plate 11 and the second coaming plate 12, certainly, can also be set according to being actually needed Put the fixed plate 3 of 3 or more than 3.The fixed plate 3 on the coaming plate 12 of fixed plate 3 and second on first coaming plate 11 is prolonged in opposite directions Stretch, i.e., the fixed plate 3 on the first coaming plate 11 extends to the second coaming plate 12, and the fixed plate 3 on the second coaming plate 12 is to the first coaming plate 11 Extension.The upper surface of that one end that the fixed plate 3 on the coaming plate 12 of fixed plate 3 and second on the first coaming plate 11 extends towards is all provided with There is vertically extending guide pillar 31, the jack to match with guide pillar 31 is provided with PCB100.Due to PCB100 corner location Electrical equipment original paper is not often welded, and the jack can specifically be located at PCB100 corner, then four guide pillars 31 can be plugged on respectively , then can be from Corner Strapped PCB100 in the preset jack of the upper corners of PCB100.The fixed plate 3 is in place in the institute of sliding groove 20 The top put is further opened with vertically extending through hole, screw 41 is equipped with the through hole, and the screw 41 extend into slip It can slide in groove 20 and along the bearing of trend of sliding groove 20, one end that screw 41 is extended in sliding groove 20 is fixed with head of screw 42, The width of the head of screw 42 is more than the width of sliding groove notch 21, then head of screw 42 is without departing from sliding groove 20, and screw 41 can To be moved in sliding groove 20.The screw 41 is also socketed with nut 43 in the top of fixed plate 3, when needing to fix fixed plate 3 When, nut 43 can be tightened, then nut 43 and head of screw 42 grip fixed plate 3, can be with when needing to loosen fixed plate 3 Gripping to fixed plate 3 will be loosened by loosening nut 43, nut 43 and head of screw 42, and fixed plate 3 can be with respect to sliding groove 20 Change position.Wherein, nut 43 can select manual adjusting nut, its size can set it is larger, in order to which worker can be with hand Dynamic regulation, it is more convenient.

In one embodiment, the sliding groove 20 is provided at both ends with the locating part 200 being fastened in sliding groove 20, limit Position part 200 can limit the sliding scale of fixed plate 3, prevent from removing PCB100 the working region of chip mounter.

In one embodiment, the fixed plate 3 is triangle plate shape, and width subtracts fixed plate 3 successively in the direction of extension Small, this sets the materials that can reduce fixed plate 3, with cost-effective.

Above content is to combine specific embodiment further detailed description of the utility model, it is impossible to is assert Specific implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field For, without departing from the concept of the premise utility, some simple deduction or replace can also be made.
