Abstract

The utility model relates to a pneumatic full floating clamp, which belongs to a component of a numerical control punch and is used for clamping metal plates which need to be processed. The utility model belongs to the technical field of the numerical control punch. The utility model comprises a cylinder, an upper and a lower clamp bodies which are connected with the lower part of the cylinder and a dovetail seat fixing device. The utility model is characterized in that both sides of the cylinder are provided with vertical stepped holes; the interior of each stepped hole is sheathed with a guiding axle of a spring; both ends of the guiding axle are fixedly connected with the dovetail seat fixing device. Because both sides of the cylinder are provided with the vertical stepped holes and the interior of each stepped hole is sheathed with the guiding axle of a spring, the utility model changes a connecting structure of the cylinder and the dovetail seat fixing device; when the upper and the lower clamp bodies which are fixedly connected with the cylinder are affected by the metal plates which are clamped by the upper and the lower clamp bodies because of flopping up and down, with using the elastic force of the spring, the cylinder and the upper and the lower clamp bodies of the cylinder which are fixedly connected with the cylinder can move up and down in a linear mode along the guiding axle; thus, the utility model achieves the purpose that the upper and the lower clamp bodies and the metal plates which are clamped by the upper and the lower clamp bodies can make same direction motion, and is favorable for protecting the metal plates and improving quality of press processing of the metal plates.

Description

Pneumatic Full Floating Clamp

Technical field

The utility model relates to a kind of Pneumatic Full Floating Clamp, is the parts in the numerical control press, is used for the sheet metal of clamping processing, belongs to the numerical control press technical field.

Background technology

Numerical control press is a kind of visual plant of sheet metal processing, sheet metal is passed by the fixing clamp clamping in slide carriage front end both sides on the work top of numerical control press, existing clamp is mainly by cylinder, the last lower clamp that the cylinder bottom connects, the dovetail mount fixture of cylinder and last lower clamp pin joint constitutes, the action of air cylinder driven upper clamp makes it to clamp with lower clamp or unclamp, the maximum deficiency of this clamp is to be connected with bearing pin because of between cylinder and last lower clamp and the dovetail mount fixture, cylinder and last lower clamp are that the former heart swings up and down slightly with bearing pin, the distance that swings up and down is controlled by the displacement of straight pin in the front end hole slot of dovetail mount fixture bottom, sheet metal is on the numerical control press work top when mobile, some bobs are arranged, and existing clamp can only swing up and down around the former heart slightly because of its structural factor, and can not doing up and down with the sheet metal of its clamping, straight line moves.

Summary of the invention

The purpose of this utility model is can only swing up and down slightly around the former heart, can not move with straight line about the sheet metal work of its clamping because of its structural factor at the clamp on the existing numerical control press work top, thereby can influence the deficiency of sheet metal crudy, a kind of Pneumatic Full Floating Clamp that straight line moves about can doing with the sheet metal of its clamping is provided.

The purpose of this utility model is achieved through the following technical solutions, a kind of Pneumatic Full Floating Clamp, comprise last lower clamp and dovetail mount fixture that cylinder, cylinder bottom connect, it is characterized in that described cylinder both sides are provided with that vertical shoulder hole, shoulder hole built-inly are with the axis of guide of spring, the two ends and the dovetail mount fixture company of the axis of guide consolidates.

The utility model reaches at the built-in axis of guide that is with spring of shoulder hole by vertical shoulder hole is set in the cylinder both sides; changed the syndeton of cylinder and dovetail mount fixture; when connecting sheet metal bob that solid last lower clamp is subjected to its clamping and influence with cylinder; utilize the elastic force of spring; make cylinder and cylinder connect solid last lower clamp and do up and down along the axis of guide that straight line moves; last lower clamp and the homodromous purpose of sheet metal that is subjected to its clamping have been realized; help protecting sheet metal and improve the metallic plate punching crudy; the utility model is simple in structure, has very strong practicality.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram;

Fig. 2 is the utility model plan structure schematic diagram;

Fig. 3 is the utility model broken section structural representation;

Among the figure, 1 cylinder, 2 upper clamps, 3 lower clamps, 4 dovetail mount fixtures, 5 shoulder holes, 6 axis of guides, 7 springs, 8 pins.

The specific embodiment

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is made of cylinder 1, upper clamp 2, lower clamp 3, dovetail mount fixture 4, the bottom of cylinder 1 connects upper clamp 2 and lower clamp 3 admittedly, the both sides of cylinder 1 are provided with vertical shoulder hole 5, inserting spring 7 in the macropore of shoulder hole 5, the axis of guide 6 passes the vertical shoulder hole 5 of cylinder 1 both sides, the hole of the vertical shoulder hole 5 of dovetail mount fixture 4 corresponding cylinders 1 both sides is passed at its two ends, the upper end of the axis of guide 6 is big footpath, its bottom can have screw thread, and the bottom is by pin 8 location.

Claims

1, a kind of Pneumatic Full Floating Clamp, comprise last lower clamp and dovetail mount fixture that cylinder, cylinder bottom connect, it is characterized in that described cylinder both sides are provided with that vertical shoulder hole, shoulder hole built-inly are with the axis of guide of spring, the two ends and the dovetail mount fixture company of the axis of guide consolidates.

2, Pneumatic Full Floating Clamp according to claim 1 is characterized in that the upper end of the axis of guide is big footpath, and its bottom can have screw thread, and the bottom is located by pin.
