Description
Technical Field
The utility model relates to a frock clamp technical field especially relates to a boring grab for irregular work piece.
Background
When a workpiece with an irregular outer shape as shown in fig. 1 is machined, it is difficult to position and clamp the workpiece with a certain surface as a reference surface, so that it is difficult to drill a hole in the side surface, and since only one hole needs to be drilled, a worker usually uses a simple tool which cannot position and press the workpiece well in order to improve efficiency, and the drilling accuracy is insufficient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a not enough to prior art, and provide a boring grab for irregular work piece, it utilizes the hole on the work piece landing leg as the location basic point, then utilizes the fixed work piece of clamp plate.
The utility model provides a technical scheme that its technical problem adopted is: the drilling clamp for the irregular workpiece comprises a base plate fixed on a workbench, wherein the base plate is provided with a first vertical plate and a second vertical plate which are parallel to each other, the first vertical plate is provided with two positioning pins, the second vertical plate is connected with a pressing plate through two sliding rods in a sliding mode, and the second vertical plate is provided with a cylinder for driving the pressing plate to move.
Further, a third vertical plate is arranged on the bottom plate, and the third vertical plate, the first vertical plate and the second vertical plate form an n-shaped structure.
Furthermore, the length of the positioning pin is smaller than the depth of a hole for clamping and positioning the workpiece.
Furthermore, the two positioning pins correspond to two holes for clamping and positioning on the workpiece and can be in clearance fit with the two holes.
Furthermore, a top plate is arranged at the top of the first vertical plate, and a positioning hole is formed in the position, to be processed, of the workpiece, of the top plate.
The utility model has the advantages that: a drilling fixture for irregular workpieces comprises a bottom plate fixed on a workbench, wherein a first vertical plate and a second vertical plate which are parallel to each other are arranged on the bottom plate, two positioning pins are arranged on the first vertical plate, a pressing plate is connected to the second vertical plate through two sliding rods in a sliding mode, and an air cylinder for driving the pressing plate to move is arranged on the second vertical plate. The utility model discloses utilize the hole on the work piece landing leg as the location benchmark, can fix a position and fixed work piece fast accurate to improve the machining precision of work piece.

Detailed Description
The following detailed description of the present invention is provided with reference to the accompanying drawings and specific embodiments, and is not intended to limit the scope of the invention.
As shown in fig. 2 and 3, the drilling jig for irregular workpieces of the embodiment includes a bottom plate 1 fixed on a workbench, the bottom plate 1 is provided with a first vertical plate 2 and a second vertical plate 3 which are parallel to each other, the first vertical plate 1 is provided with two positioning pins 4, the second vertical plate 3 is slidably connected with a pressing plate 6 through two sliding rods 5, and the second vertical plate 3 is provided with a cylinder 7 driving the pressing plate 6 to move.
The embodiment is used for positioning and clamping the workpiece during drilling the side surface of the workpiece shown in fig. 1, and during operation, the positioning pins 4 are sleeved in the holes on the two supporting legs of the workpiece respectively, and then the workpiece is pressed by the pressing plate 6, so that the workpiece can be positioned and clamped; then, holes are drilled in the top of the workpiece, and since a rocker drill is usually used for drilling holes, in order to improve the positioning efficiency and accuracy, the top plate 9 is arranged on the top of the first upright plate 2, the top plate 9 is provided with a positioning hole 91 at the position of the hole to be machined in the workpiece, and a drill can pass through the positioning hole 91 during drilling to machine the workpiece.
In addition, in order to improve the rigidity of the first vertical plate 2 and the second vertical plate 3 and prevent the precision from being reduced due to deformation, the base plate 1 is provided with a third vertical plate 8, and the third vertical plate 8, the first vertical plate 2 and the second vertical plate 3 form an n shape.
It should be finally noted that the above embodiments are only used for illustrating the technical solutions of the present invention, and for the convenience of the description of the technical solutions, the adopted front, back, left, right, upper, middle and lower directions are set based on the drawings, not the limitation of the protection scope of the present invention, although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
