Abstract
The utility model discloses a retractable clamping mechanism for a hole, belonging to a fixture. The utility model aims at providing a fixture which is convenient and quick in workpiece clamping and low in labor intensity, and can be applicable to a hole with small diameter. The retractable clamping mechanism comprises a base and pressing plates, wherein a positioning guide sleeve (3) is fixed on the base (4), a pull rod (8) provided with a sliding chute (9) penetrates through the base (4) and the positioning guide sleeve (3) to extend out upwards, a sliding pin (2) is arranged in the sliding chute (9), two ends of the sliding pin are respectively articulated with one pressing plate (6), other ends of all the pressing plates (6) are respectively articulated with a connecting rod (7), and other ends of all the connecting rods (7) are articulated on the pull rod (8) together. The retractable clamping mechanism has the advantages of simple structure, convenience and rapidness in operation, high efficiency and the like; therefore, the retractable clamping mechanism is a fixture which is suitable for realizing the positioning and clamping for a workpiece by utilizing the hole in the workpiece.
Description
Technical field
The utility model relates to a kind of technological equipment, relates in particular to a kind of anchor clamps.
Background technology:As everyone knows, in machining, usually need utilize hole on the workpiece to realize the location and the clamping of workpiece, and present clamp mechanism all is made up of usually screw rod and opening pressing plate.Not only clamping workpiece bothers this traditional clamp mechanism, efficient is low, and labour intensity is big.
Summary of the invention:In order to overcome the defective that exists in the prior art, the utility model aims to provide the contraction type hole that a kind of clamping workpiece is convenient and swift, labour intensity is little and uses clamp mechanism.
To achieve these goals, the utility model adopts following technical scheme: it comprises base and pressing plate; Be fixed with the positioning and guiding cover on the base; The pull bar that is provided with chute passes base and the positioning and guiding cover upwards stretches out, and is provided with sliding pin in the chute, and the two ends of this sliding pin respectively are hinged with a block pressur plate; The other end of each pressing plate is hinged with a connecting rod respectively, and the other end of each connecting rod is hinged on the pull bar jointly.
The positioning and guiding cover is fixed on the base through screw thread.
With prior art relatively, the utility model has been owing to adopted technique scheme, therefore thoroughly overcome conventional brace and in the process of clamping and dismounting workpiece, need repeatedly pick and place pressing plate, repeatedly tighten or unclamp the defective of nut; The utlity model has convenient to operation, labour intensity is little, the efficient advantages of higher.
