Pressing plate type floating clamp

Abstract

The invention discloses a pressing plate type floating clamp. The pressing plate type floating clamp comprises a fixing mechanism and a clamping mechanism. The fixing mechanism comprises an upper base, a lower base and a protrusion arranged on the upper base. The clamping mechanism comprises a positioning block, a clamping arm, a pressing plate, a supporting plate, and a bolt. The clamping arm and the pressing plate are used for clamping a workpiece. The supporting plate is used for supporting the pressing plate. The bolt penetrates the pressing plate and the supporting plate and is arranged in the positioning block. The end, away from the clamped workpiece, of the clamping arm is hinged to the lower base. The positioning block is fixedly connected with the lower base. A first hole and a second hole are formed in the positioning block are perpendicularly communicated with each other. A first ejector rod is arranged in the pressing plate and is connected into the first hole in a sliding manner. A second ejector rod is arranged in the second hole. The end faces, abutting against each other, of the first ejector rod and the second ejector rod are matched conical faces. The other end of the second ejector rod is opposite to the clamping arm. The bolt is sleeved and connected with a nut. The nut is arranged above the pressing plate. A spring piece is arranged between the supporting plate and the positioning block. By means of the scheme, the problems that an existing die is complex in structure, poor in clamping effect and low in production efficiency are solved.

Description

technical field

[0001] The invention relates to the field of clamps, in particular to a pressing plate type floating clamp. Background technique

[0002] In a broad sense, any process in the process, the device used to install the workpiece quickly, conveniently and safely, can be called a fixture. Such as welding fixtures, inspection fixtures, assembly fixtures, machine tool fixtures, etc. Among them, machine tool fixtures are the most common, often referred to as fixtures. When processing a workpiece on a machine tool, in order to make the surface of the workpiece meet the technical requirements such as the size, geometric shape, and position accuracy with other surfaces specified in the drawing, the workpiece must be installed and clamped firmly before processing. Fixtures are usually composed of positioning elements, clamping devices, tool setting guide elements, indexing devices, connecting elements, and clamp bodies.
