Plane floating clamp and floating structure thereof

Abstract

The invention provides a plane floating clamp and a floating structure thereof and relates to the technical field of machining clamps. The floating structure comprises a base A provided with two guiding columns, a base B provided with two guiding columns, and a floating block arranged between the base A and the base B and provided with a long-strip-shaped first guiding groove and a long-strip-shaped second guiding groove; the included angle between the first guiding groove and the second guiding groove is 90 degrees; the two guiding columns of the base A are inserted into the first guiding groove and can move back and forth in the length direction of the first guiding groove; and the two guiding columns of the base B are inserted into the second guiding groove and can move back and forth in the length direction of the second guiding groove. The plane floating clamp and the floating structure of the plane floating clamp are very simple in overall structure and has the beneficial effects of being convenient to install and low in manufacturing cost, and the plane floating clamp and the floating structure of the plane floating clamp are suitable for large-scale application and popularization.

Description

technical field [0001] The invention relates to the technical field of machining fixtures, in particular to a plane floating fixture and its floating structure. Background technique [0002] The roller body assembly is one of the key parts of the fuel injection pump. It is mainly composed of a roller body, a roller and a roller pin. There are two pin holes on the roller body (see figure 1 As shown), the coaxiality, dimensional accuracy and roughness of the pin hole play a decisive role in whether the product can finally meet the design requirements. In order to ensure the accuracy, the last finishing process of the pin hole is usually completed on a honing machine. During honing, the roller body is clamped by a floating fixture. [0003] Most of the existing floating fixtures for honing machines have complex structures, such as the three-dimensional floating fixtures for high-precision CNC honing machines disclosed in the Chinese utility model patent with the publication nu...

Problems solved by technology

[0003] Most of the existing floating fixtures for honing machines have complicated structures, such as the three-dimensional floating fixtures for high-precision CNC honing machines disclosed in the Chinese utility model patent whose publication number is CN201544114U, and the special plane floating fixtures for precision honing machines disclosed in the Chinese invention patent with the publication number CN104209860A. Fixtures, these floating fixtures rely on hydraulic pressure / spring force to control the floating of the workpiece, which is troublesome to install and expensive to manufacture
