Abstract
The utility model provides a floating type clamp of a punching machine tool, which is arranged on a feeding mechanism of the punching machine tool, and comprises an installation seat, a plurality of expansion devices and a plurality of floating clamping mechanisms, wherein the installation seat is fixed on the feeding mechanism, each floating clamping mechanism comprises an upper clamping mechanism and a lower clamping mechanism, the upper clamping mechanism and the lower clamping mechanism respectively comprise a clamping piece base, a clamping piece and a central rotating shaft running through the clamping piece base and the clamping piece, and two sides of the central rotating shaft are provided with elastic elements; the device clamps the metal plate by matching the upper clamping mechanism and the lower clamping mechanism; the clamping piece can be prevented from being in point contact with the metal plate through free swinging of the clamping piece, so that the clamping stability is improved; the pressure of a stress surface is increased by extruding the small rubber balls by the metal plate and the clamping pieces, so that the friction is increased, and the stable clamping is ensured; the elastic element plays a role in shock absorption and buffering, so that the instant clamping force of the clamp when clamping the workpiece is reduced, and the workpiece is protected from being damaged.
Description
Technical Field
The utility model relates to an anchor clamps, concretely relates to floating anchor clamps of punching press lathe.
Background
Stamping machine tool adds man-hour to the sheet metal component, needs to be fixed to the panel beating unevenness usually has certain range in the part, leads to conventional anchor clamps to appear the point contact easily when the centre gripping panel beating, thereby the centre gripping is unstable, thereby the pay-off is inhomogeneous.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simple structure can stabilize the floating anchor clamps of centre gripping. The utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a floating type clamp of a punching machine tool is arranged on a feeding mechanism of the punching machine tool and comprises an installation seat, a plurality of telescopic devices and a plurality of floating clamping mechanisms; wherein:
the mounting seat is fixed on the feeding mechanism, the telescopic device comprises a hydraulic cylinder and a telescopic rod, one end of the telescopic rod is arranged in the hydraulic cylinder, and the other end of the telescopic rod is connected with the floating clamping mechanism; the floating clamping mechanism comprises an upper clamping mechanism and a lower clamping mechanism, and the lower clamping mechanism is positioned right below the upper clamping mechanism and is fixed on the mounting seat; the upper clamping mechanism and the lower clamping mechanism respectively comprise a clamping piece base, a clamping piece and a central rotating shaft penetrating through the clamping piece base and the clamping piece, elastic elements are arranged on two sides of the central rotating shaft, one end of each elastic element is connected to the clamping piece base, and the other end of each elastic element is connected to the clamping piece; the end face of the clamping piece is provided with a plurality of elastic small rubber balls and fixing holes.
Alternatively or preferably, the swing angle of the clamping piece along the central rotating shaft at two sides is 0-45 degrees.
Alternatively or preferably, the shape of the fixing hole matches with a rubber ball, and the rubber ball is fixed in the fixing hole.
Based on the technical scheme, the following technical effects can be generated:
a floating anchor clamps of punching press lathe, overall structure is simple, operation convenient to use, stability is good, the reliability is high. The device drives the upper clamping mechanism to move through the telescopic device, and the upper clamping mechanism is matched with the lower clamping mechanism to clamp the metal plate; the clamping piece can be prevented from being in point contact with the metal plate through free swinging of the clamping piece, so that the clamping stability is improved; the pressure of a stress surface is increased by extruding the small rubber balls by the metal plate and the clamping pieces, so that the friction is increased, and the stable clamping is ensured; elastic elements are arranged on two sides of the central rotating shaft, and the elastic elements play a role in shock absorption and buffering, so that the instant clamping force of the clamp when clamping a workpiece is reduced, and the workpiece is protected from being damaged.
