Preferably, the upper section of the pull rod is provided with a limiting groove, the width of the limiting groove is matched with the thickness of the pressing plate, and one side of the pressing plate is provided with a clamping channel matched with the limiting groove.
Preferably, a handle is fixedly connected to the top of the pressure plate.
The utility model has the beneficial effects that:
the multi-punch mounting hole has the advantages that the structure is simple, the production efficiency can be improved by simultaneously working the plurality of punches, the problems that the hole diameter of the connecting hole is wrong due to the use of wrong punches or the actual punching quantity of the connecting hole is incorrect due to order falling in the actual operation process of workers are solved, the tool cost can be reduced by the aid of the plurality of groups of punch mounting holes, the limiting grooves are matched with the clamping channels, the pull rod can be conveniently clamped or the pressing plate can be conveniently released, the handle at the top of the pressing plate can prevent the pressing plate from pressing the workers, and the jig is safer and more reliable.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic top view of the worktable of the present invention.
In the figure: 1. the device comprises a handle, a pressing plate, a clamping channel, a flange, a pull rod, a limiting groove, a punch mounting hole, a shoulder, a workbench and a cylinder, wherein the pressing plate is 2, the clamping channel is 3, the flange is 4, the pull rod is 5, the limiting groove is 6, the punch is 7, the punch mounting hole is 8, the shoulder is 9, the workbench is 10, and the cylinder is 11.
Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
As shown in the figure, the punching device comprises a workbench 10, a pull rod 5 penetrating the middle of the workbench, a plurality of punches 7 arranged on the periphery of the pull rod and a cylinder 11 fixedly connected to the bottom of the workbench, wherein the punches work simultaneously to improve the production efficiency and prevent the problems that in the actual operation process, workers use wrong punches to cause the aperture error of a connecting hole or the punching quantity of the actual connecting hole is incorrect due to the falling sequence, the diameter of the pull rod is matched with the diameter of a flange hole of a flange 4 to be processed, the pull rod is used for inserting the flange hole in the middle of the flange to be processed, a convex shoulder 9 is arranged on the lower section of the pull rod, a pressure plate 2 is clamped on the upper section of the pull rod, the distance between the upper surface of the convex shoulder and the lower surface of the pressure plate is matched with the thickness of the flange to be processed, and the pressure plate is used for fixing the flange to be processed between the convex shoulder and the pressure plate.
The workstation is equipped with the multiunit drift mounting hole 8 with different specification flange connecting hole looks adaptation at the pull rod periphery, and this embodiment is equipped with two sets of drift mounting holes, and the accessible is changed drift mounted position and is punched a hole to different specification flanges to reduce the cost of one set of frock.
The bottom of the punch is connected with the punch mounting hole in an interference fit mode, the structure is simple, the centering performance is good, the impact resistance is good, and the strength of the bottom of the punch is weakened.
