Technical field
The utility model relates to the plant equipment in the electronics and the communications field, relates to be applied to a kind of anchor clamps in the plate or rather.
Background technology
Plate at computer, (Printed Circuit Board in manufacturing PCB), production and the test process, often need carry out accurate clamping location to plate as printed circuit board (PCB), according to the difference of positioning reference, roughly can be divided into location, limit, location, hole and central shaft location etc.
Wherein, the location, limit generally is to adopt an edge of circuit board to locate with the mode that an end of anchor clamps aligns, and board edge is tangible entity, can contact closely with anchor clamps one reference edge and cooperate, and then circuit board is positioned on the anchor clamps exactly.Yet the circuit board yardstick that different manufacturers is produced is different, and therefore, this locate mode does not have versatility, need design different anchor clamps at the circuit board of different size.
The location, hole then is to be provided with calibration hole on circuit board, and also is provided with a location hole on the anchor clamps.Circuit board then is to pass calibration hole and location hole is fixed on the anchor clamps by a bolt.Hole location is the same with the location, limit, also be the tangible entity of employing contact closely with cooperate, and circuit board is positioned on the corresponding anchor clamps exactly.Yet, this locate mode need be provided with the hole on circuit board, thereby wasted the confined space on the circuit board, and development of science and technology makes more and more miniaturization of circuit board, space resources on the circuit board is also more and more valuable, therefore, the direction of hole location incompatibility technical development, use aspect the location of the circuit board of computer can be gradually minimizing.
Central shaft location is that the plate central axis is alignd with the central axis of anchor clamps, and central axis is illusory, promptly with respect to the plate two edges and definite.Therefore, the central shaft location is what to be located by two opposite side of plate indirectly.How accurately and apace to find central axis accurately, position and clamping, become the bottleneck that influences efficiency of assembling.At present, the central shaft location mainly is a method of taking ruler measurement and setting-out.As the developed width of first measuring circuit plate, then, draw central axis in the place of a half width, then the central axis on road plate center line and the anchor clamps aligns, and clamps then.Yet the central axis location is to adopt the manual accurate and careful operation of carrying out, and very high to operator's requirement, labour intensity is also very big, and efficient is very low.According to statistics, on average finish a clamping and need 5 minutes.In addition, because manual being positioned at read scale and center line to there being the collimation error on time, therefore accurately fixed very low, in general, this kind location can cause center line that overgauge is surpassed 0.5mm.Therefore, manual central shaft is located location and the installation that also is unsuitable for the computer plate.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of anchor clamps, and these anchor clamps can be realized the automatic centering and the installation of plate, and can reduce the error in the centering process.
For achieving the above object, the utility model provides following technical scheme:
A kind of plate central axis positioning fixture, comprise first clamping plate, cooperate second clamping plate that plate is fixing with first clamping plate, wherein, second clamping plate are provided with the two centralized positioning pawls that clamp plates, this two centralized positionings pawl with respect to a location axis on second clamping plate do equidistant locking phase to or oppositely move.
Described first clamping plate by manual screw on a clamping base plate.
Described first clamping plate and second clamping plate are installed together by hand-screw, and when hand-screw unclamped, first clamping plate and second clamping plate were removed in opposite directions, and plate can be installed between first clamping plate and second clamping plate.
Described second clamping plate are provided with and drive the synchronous band that the centralized positioning pawl moves in opposite directions, and this is with synchronously and cooperates by grip block with the centralized positioning pawl, and wherein band adopts threaded engagement with grip block synchronously, and the centralized positioning pawl then is to be fixed on the grip block.
This plate centre clamp also is provided with the centralized positioning wheel, the pivot locating wheel then drives the rotation of synchronous band, the centralized positioning wheel cooperates with synchronous being with by centralized positioning wheel bearing pin, and wherein the centralized positioning wheel is contained on the centralized positioning wheel bearing pin surely, and the projection that is provided with the bit strip cooperation is taken turns in centralized positioning.
These plate centralized positioning anchor clamps also are provided with the centralized positioning guide plate, this centralized positioning guide plate is installed in centering slide block and grip block on second clamping plate, and the centralized positioning guide plate is installed on second clamping plate by hand-screw, when hand-screw unclamps, centering slide block and grip block can move on second guide plate, when hand-screw was tightened, centering slide block and grip block then were lockable.
The plate centralized positioning anchor clamps that the utility model provides drive the centering slide block by locking phase to the centralized positioning pawl that moves and move in anchor clamps center line bilateral symmetry, thereby automatically the circuit board center line are aimed at the anchor clamps center line, and then fix.Therefore, the utility model plate centre clamp can accurately be located plate fast, and without any need for manual measurement, has eliminated the error of manual measurement, has also reduced labour intensity, raises the efficiency.
