Embodiment Construction

[0018] Such as figure 1 , 2 , 3, a support base 12 is fixedly installed on the fixture base 2, the middle part of the lever 4 is connected with the support base through the connecting shaft 6 and the joint bearing installed on the connecting shaft, and a U-shaped groove is opened at the right end of the lever. The cylindrical guide compression sleeve 8 is installed in the U-shaped groove through two symmetrical pin shafts 9 fixed on its outer surface, and a compression cylinder 1 is installed on the clamp base at the lower left end of the lever. An adjusting screw 5 is installed at the top corresponding position of the piston rod 3 in the oil cylinder.

[0019] An elastic orifice 7 is fixed on the upper end face of the support seat, the hole on the elastic orifice is concentric with the inner hole of the cylindrical guide compression sleeve, and the aperture on the elastic orifice is greater than the inner hole of the cylindrical guide compression sleeve. Three positioning b...

Abstract

The invention relates to a machine tool fixture, in particular to a special flat floating fixture for a precision honing machine. The fixture comprises a fixture base and a fixture body, and is characterized in that a supporting seat is fixedly arranged on the fixture base, and the middle of a lever is rotatably connected with the supporting seat; one end of the lever is provided with a U-shaped groove, and a cylindrical guide compaction sleeve is arranged in the U-shaped groove in the lever through two pin shafts which are symmetrically distributed and are fixedly arranged on the peripheral surface of the cylindrical guide compaction sleeve; a compaction oil cylinder is arranged on the fixture base at the lower part of the other end of the lever, and the top end of a piston rod in the compaction oil cylinder corresponds to the lower surface of the other end of the lever. The technical scheme adopts a lever principle combined with floating connection, so that the current status of the uneven distribution of compaction force can be effectively changed; the machine tool fixture has the characteristics of simple structure, convenience in adjustment, good compaction and positioning effects, high precision and the like.

Description

Technical field [0001] The invention relates to a machine tool clamp, in particular to a special plane floating clamp for precision milling machines. Background technique [0002] Honing belongs to precision machining and is the final machining of the inner hole of the part. When honing the inner hole of a part with a relatively small length and diameter, the clamping force of the fixture and the distribution of the clamping force will directly affect the dimensional accuracy and shape accuracy of the workpiece after processing. Most of the current planar floating fixtures have complex structures and are difficult to install and maintain; when the fixture clamps the workpiece, the clamping force is unevenly distributed, and it is easy to form a drum shape during processing, and the clamped workpiece is unstable; the floating range is difficult to adjust, and the processing time reaches Less than the processing requirements of the workpiece.
