Dual-positioning floating turning clamp

Abstract

The invention discloses a dual-positioning floating turning clamp which is applied to positioning and turning of a connecting rod part. The connecting rod part is provided with a positioning hole, a connecting rod and a circular arc groove. The floating turning clamp comprises a clamp body, a dual-positioning unit and a telescopic shaft sleeve mechanism. The dual-positioning unit is composed of a pin and a wedged pressing plate. The clamp body is provided with a central groove and a pin hole. The telescopic shaft sleeve mechanism is arranged in the central groove. The wedged pressing plate is detachably arranged on the clamp body. The pin penetrates through the positioning hole in the connecting rod part to be fixed to the pin hole. The wedged pressing plate fixedly clamps the connecting rod of the connecting rod part. The telescopic shaft sleeve mechanism is connected with the circular arc groove of the connecting rod part in a butting mode. By the application of the dual-positioning floating turning clamp, the dual-positioning unit and the telescopic shaft sleeve mechanism are adopted for positioning and fixing the connecting rod part, and meanwhile turning is facilitated through stretching and contraction of the telescopic shaft sleeve mechanism, so that positioning operation is convenient and fast, positioning is accurate, the turning machining yield and production efficiency are improved, and higher economic value is brought.

Description

technical field [0001] The invention relates to a turning fixture, in particular to a double-positioning floating turning fixture. Background technique [0002] Turning fixtures are used for turning and clamping of turning workpieces. Generally, a single piece is used for positioning and clamping, and then the turning operation is performed after clamping. [0003] In the prior art, it is extremely difficult to use the single-piece positioning and clamping in the prior art for the turned parts with special-shaped connecting rods and the rotating parts that are not good at processing by the lathe. Too loose positioning and clamping of the single-piece will lead to During the process, the turning workpiece is displaced, resulting in unqualified turning of the turning workpiece, and too tight positioning and clamping of a single piece can easily lead to deformation of the turning workpiece, so the requirements for tooling are extremely high, and the work efficiency is low, and ...
