Problems solved by technology

Among them, the former not only needs to prepare a large number of shim irons, but also it will be very difficult once fine adjustment is required; in addition, multiple shim irons support the workpiece, due to the existence of gaps, the stability is poor, and when the diameter of the workpiece changes greatly, it often cannot meet the requirements. positioning requirements
The latter, due to the existence of thread manufacturing errors, when the V-shaped blocks are used in pairs, it is difficult to ensure the horizontal center alignment of the V-shaped blocks on both sides; in addition, when the workpiece is supported on the V-shaped block to adjust the distance, due to the contact between the workpiece and the V-shaped block Due to the existence of friction between surfaces, the adjustment torque is relatively large, which is easy to scratch the contact surface, which is not conducive to long-term use; if the workpiece is lifted, adjusted and then put down, repeated adjustments are required, and the operation is cumbersome, which is not conducive to batch processing
[0003] In short, there are defects in the versatility, accuracy and convenience of operation of the existing positioning support, which affects production efficiency

Abstract

The invention relates to a high-accuracy universal adjustable V-shaped positioning tool, and belongs to the technical field of machining. One of two V-shaped support assemblies of the tool comprises abase on a left adjustable sizing block assembly and a right adjustable sizing block assembly; a left sliding block assembly and a right sliding block assembly separated relatively are arranged on each base; a sliding ring is arranged under each sliding block assembly; the sliding rings and adjusting screw rods form screw pairs; the adjusting screw rods under each left sliding block assembly and each right sliding block assembly are provided with screw threads with opposite rotation directions; the adjacent ends of each two adjusting screw rods are fixedly connected through a clamping couplingassembly; each adjustable sizing block assembly comprises a lower base; an adjusting bolt of each adjustable sizing block assembly and a middle sliding block form a screw pair; the upper surface of each middle sliding block is laminated with the lower surface of an upper pressing block; the upper pressing blocks and the bases form vertical movement pairs; and end surface meshing structures are formed at opposite ends of the adjusting bolts of the left adjustable sizing block assemblies and the right adjustable sizing block assemblies, and mesh with corresponding structures at two ends of thecoupling assemblies, so that couplings are restrained. The high-accuracy universal adjustable V-shaped positioning tool provided by the invention is suitable for step shaft parts with various specifications, good in universality, convenient to operate, and high in accuracy.

Description

technical field [0001] The invention relates to a tool, in particular to a high-precision universal adjustable V-shaped positioning tool, which belongs to the technical field of mechanical processing. Background technique [0002] When machining shaft parts, especially shaft parts with steps, on a horizontal machining center, it is necessary to make a positioning support tool to keep the axis of the workpiece horizontal. There are mainly two types of existing positioning supports: fixed V-shaped blocks for positioning with pad irons and adjustable pitch V-shaped blocks for positioning by means of threads. Among them, the former not only needs to prepare a large number of shim irons, but also it will be very difficult once fine adjustment is required; in addition, multiple shim irons support the workpiece, due to the existence of gaps, the stability is poor, and when the diameter of the workpiece changes greatly, it often cannot meet the requirements. targeting requirements....
