Description

Attitude fine-tuning device

technical field

The invention relates to a posture micro-adjustment device, which belongs to the field of micro-processing equipment.

Background technique

With the rapid development of modern science and technology, there is an increasing demand for micro-parts in the fields of biomedicine, aerospace, national defense, automobiles and high-tech electronic products. Micro-processing equipment is the basis for manufacturing these micro-parts. Due to the small machining allowance, from the micron level to the millimeter level, the attitude accuracy of the workpiece seriously affects the position accuracy of the workpiece, and affects the precision of the micromachining of the workpiece to a large extent. The existing workpiece posture adjustments are all adjusted on the standard platform without the machine tool, and then clamped to the machine tool workbench, which causes repeated positioning errors due to inconsistent benchmarks, so that the workpiece posture cannot be adjusted efficiently and with high precision.

The research and development of attitude micro-adjustment devices suitable for placing workpieces is of great significance for promoting the innovation and development of micro-processing equipment, especially for promoting the development of micro-technology.

Contents of the invention

The object of the present invention is to provide a high-efficiency and high-precision attitude fine-tuning device that can overcome the above defects. Its technical solution is:

A posture micro-adjustment device is characterized in that it includes a concave base, a worktable, 4 wedge blocks, screws and nuts, wherein a cross-shaped groove is provided on the inner bottom surface of the concave base, and the 4 grooves The branches extend to the inner wall of the concave base, and the four ends of the groove are evenly arranged along the circumference of the concave base, and the four wedges are placed in the four branches of the groove; corresponding to the four wedges, the working table There are also 4 grooves with the same slope on the bottom surface. The worktable is supported on 4 wedge-shaped blocks. The grooves on the bottom surface coincide with the wedge-shaped blocks. There is a gap between the worktable and the concave base; A pair of holes are provided on the side wall corresponding to each end of the groove, which are screw holes and through holes respectively, wherein a screw is installed in the screw hole, and the screw thread passes through the side wall of the concave base and rests on the wedge block A screw with a nut is installed in the through hole, and the screw thread passes through the nut and the side wall of the concave base, and the end thread is screwed into the wedge block; in addition, the concave base is in the middle of two adjacent pairs of holes. There is a threaded hole on the side wall of the concave base, and a screw is installed in the threaded hole. The screw thread passes through the side wall of the concave base and is placed on the workbench; 4 threaded holes are evenly distributed along the circumference of the concave base. , and all screw holes, through holes and threaded holes are located at the same height of the side wall.

In the posture micro-adjustment device, the axis of each screw is perpendicular to the corresponding surface on the workbench, and the end surface of the wedge-shaped block through which the screw penetrates is parallel to the corresponding surface on the workbench.

Compared with the prior art, the present invention has the advantages of:

1. It can be adjusted on the machine with high efficiency;

2. Avoid secondary clamping, high precision;

3. The structure is simple, easy to manufacture and reduce the cost.
