Embodiment Construction

[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, and the present invention is not limited to the following embodiments.

[0038] Such as figure 1 As shown, the leveling and centering micro-motion workbench of the present invention mainly includes a base 10, a leveling and centering body 8 installed on the base 10, and a working platform 2 for placing workpieces. Establish on leveling and centering body 8 and comprise centering mechanism and leveling mechanism.

[0039] Such as Figure 2 to Figure 9 , the whole leveling and centering body 8 is formed by wire cutting of a cuboid steel block. The leveling mechanism adopts the four-point leveling principle and the flexible hinge mechanism to realize the leveling function. The leveling mechanism is divided into three layers. The upper layer ① is connected with the working platform 2 where the workpiece is placed by four screws, and the middle laye...

Abstract

The invention discloses a leveling and aligning micro displacement worktable, which comprises a base, a cuboid leveling and aligning body arranged on the base and a working platform arranged on the leveling and aligning body for accommodating a workpiece, wherein the leveling and aligning body comprises a leveling mechanism and an aligning mechanism; the leveling mechanism comprises an upper layer, a middle layer and a lower layer, dual-edge flexible hinge structures are processed between the upper layer and the middle layer and between the middle layer and the lower layer, and the two dual-edge flexible hinge structures are mutually vertical axially; the other side of the leveling and aligning body is correspondingly provided with a leveling baffle, the leveling baffle is provided with a leveling screw for level adjustment of the micro displacement worktable, and the sharp end of the leveling screw is inserted in a gap between the dual-edge flexible hinge structures. Leveling and aligning are integrated in the device, and the structure is simple; quick aligning in X and Y directions can be realized, the workpiece position is adjusted more accurately and stably, an adjustment mechanism bears small friction, the guiding precision is high, and repeatability is good.

Description

【Technical field】 [0001] The invention belongs to the technical field of precision measurement, and in particular relates to a micro-motion workbench for leveling and centering. 【Background technique】 [0002] The leveling and centering micro-motion table is a very critical precision device for large-scale CNC contour measurement equipment such as gear measurement centers, cylindricity meters, and turbine blade measurements. Axis alignment coincidence. At present, some relevant scientific research institutions, colleges and enterprises in my country have achieved rapid development in the research and development of accessory equipment such as gear measurement and roundness (cylindricity) measurement. The degree of marketization of optional accessories is not high, especially in terms of accuracy, equipment efficiency, and degree of automation, which are far behind foreign products. [0003] The structure of workpiece leveling and centering at home and abroad is mainly class...
