Improving as one, also comprising the clamping device be arranged on for base and cap locations being fixed on base.
Further, described clamping device comprises and is arranged on base and does not have two of boss limits step up screw; The screw that steps up wherein on a limit is aimed at the boss of opposite side, and the screw that steps up on another limit is aimed in the middle of opposite side two boss, described in step up screw precession promote cover plate and boss tangent, and cover plate to be fixed.
Improve as one, also comprise setting on the cover board for the fixture of fixing workpiece.
Further, described fixture comprises setting on the cover board for placing the fixing step of workpiece and being arranged on the hold-down screw of fixing step outer ledge, hold-down screw described in precession, and described workpiece and fixing step are fixedly clamped by head of screw.
Improve as one, described cover plate is also provided with the upset mark as upset benchmark.
Further, an angle in four of cover plate angles differs from and arranges with the mode at another three angles by the employing of described upset mark.
A kind of frock clamp of the utility model, by the cover board arranging the fixture being used for fixing workpiece, the positioner arranging the clamping device for base and cap locations being fixed and be used for determining position between base and cover plate on base; Exact constrain is carried out to the position of workpiece, thus when the pattern of workpiece positive and negative needs to add the heart to guarantee that the pattern human error processed is smaller man-hour, be not easy to cause part to process unsuccessfully, simple to operate, the product yield of processing is high.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is the overall schematic of a kind of frock clamp of the utility model;
Fig. 2 is the base schematic diagram of a kind of frock clamp of the utility model.
Detailed description of the invention
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 shown in Figure 1-2, a kind of frock clamp of the utility model, comprise base 1 and cover plate 2, described base 1 is provided with locating hole, and is fixed on Laser Processing platform by locating hole; Have the first through hole in the middle of base 1, cover plate 2 is placed in the first through hole, and cover plate 2 is for holding workpiece; Be arranged on cover plate 2 comprises for the fixture 4 of fixing workpiece 5, fixture 4 and be arranged on cover plate 2 for placing the fixing step of workpiece and being arranged on the hold-down screw of fixing step outer ledge, hold-down screw described in precession, described workpiece and fixing step are fixedly clamped by head of screw.Fixture 4 is the hold-down screw of at least three be arranged on cover plate 2 in the present embodiment, and what select in the present embodiment is four hold-down screws.
The utility model also comprises a positioner, for determining position between base 1 and cover plate 2.Positioner is the boss 11 be arranged on inside the first through hole, and limit and the boss 11 of described cover plate 2 are tangent.According to the demand of workpiece or cover plate 2, the first through hole on base 1 can be set to circle or other polygons, reach best to make effect, the first through hole adopted in the present embodiment is square through hole, described boss is arranged on two adjacent limits of square through hole, the quantity of boss 11 can be determined according to actual conditions, determine according to three the boss 11 that positioning principle selects described in three in the present embodiment, a limit of described square through hole is provided with a boss 11, and adjacent another limit is provided with two boss 11 with it.
Further comprise clamping device 3, this clamping device 3 is arranged on for base and cap locations being fixed on base, and clamping device comprises and is arranged on base and do not have two of boss limits step up screw 12; The screw 12 that steps up wherein on a limit is aimed at the boss of opposite side, and the screw that steps up on another limit is aimed in the middle of opposite side two boss, described in step up screw precession promote cover plate and boss tangent, and coordinate with boss cover plate be fixed.Concrete, the screw that steps up of both direction carries out precession by stepping up screw, and the boss through base medial surface cover plate being advanced into face in contrast carries out tangent, and cover plate clamping makes position between base and cover plate fix by precession further.
Also comprise setting on the cover board for the fixture of fixing workpiece.Fixture comprises and is arranged on cover plate second through hole edge for placing the fixing step of workpiece and being arranged on the hold-down screw of fixing step outer ledge, hold-down screw described in precession, and described workpiece and fixing step are fixedly clamped by head of screw.Described hold-down screw is arranged on fixing step outer ledge, adopts four hold-down screws in the present embodiment.
In existing fixture, directly connected with two limits inside the first through hole of base by two limits of stepping up the propelling cover plate of screw, because cover plate and the first through hole exist the error adding man-hour, therefore the position be fixedly connected again after upset is probably different from the position originally connected, and therefore easily causes upset deviation.And the utility model, by setting up boss inside the first through hole of base, the limit of cover plate is connected on boss, utilizes three to determine positioning principle, determines the position processed; The back shroud of upset is still tangent with boss, and the shift in position therefore connected is not too large, and connect compared to two limits, position is relatively fixing, and upset deviation is less, meets the requirement to heart processing.Certainly, as a kind of preferred version of the present embodiment, on the cover board can also be provided with the groove guiding fixing lug boss, because the position of groove can by accurate machining control error, after the reversal, the position connected is more accurate for such cover plate and base.
In the present embodiment, on the cover board can also be provided with the upset mark as upset benchmark, after the front completion of processing of workpiece, by upset mark as upset benchmark when determining upset, cover plate be turned over turnback, then cover plate is added fastens.Wherein this upset mark can be wherein to have an angle to be arranged to different from another three angles in four of cover plate angles.Such as one of them angle of cover plate is set to right angle, another three angles are fillets; Or one of them angle of cover plate is fillet, another three angles are right angles.The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do in spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included in protection domain of the present utility model.
