Problems solved by technology

However, no matter what kind of frame is used for the inspection platform, the horizontal calibration of the reference platen is realized through repeated fine-tuning of the frame by workers and repeated level measurement of the reference platen. This kind of horizontal calibration operation is not only very troublesome, but also Moreover, it is difficult to achieve complete horizontal calibration of the reference platen in a short-term operation, and there are defects such as difficult operation and low efficiency, which affect the production efficiency of the enterprise

Embodiment Construction

[0029] see figure 1 and figure 2 : The present invention includes a reference platen 1, a frame body 2, an inclination amplification mechanism 4 and a leveling mechanism 3.

[0030] Wherein, the reference platen 1 is used as an operation platen for testing the processing accuracy of parts, and it has a rectangular structure, the top surface and the bottom surface are flat and smooth, and the two are parallel. The four corners of the reference table 1 are support points. In order to ensure the reliability of the automatic horizontal calibration and reset, each support point is required to be at the same position from the edge of the reference table 1, that is, the four support points are centered on the center point of the reference table 1 , evenly distributed on the four corners of the reference platen 1. An inclination angle sensor is arranged on the aforementioned reference platen 1, that is, a platen inclination sensor 11, through which the sensor detects whether th...

Abstract

The invention discloses a precision testing platform for a small-sized part. The precision testing platform comprises a standard platform plate, a frame body, an inclined amplifying mechanism and leveling mechanisms, wherein the standard platform plate is horizontally supported by a plurality of support columns of the frame body through elastomers; the inclined amplifying mechanism is attached to the bottom surface of the standard platform plate, supported by the leveling mechanisms, mainly comprises a hard tray, a flexible capsule and a balance steel ball, and is used for exerting leveling gravity on the leveling mechanisms; the leveling mechanisms are arranged between the support columns of the frame body and the inclined amplifying mechanism according to a lever principle, and used for performing automatic reset calibration on the standard platform plate which is unbalanced and inclined. The precision testing platform can automatically reset the standard platform plate, which is unbalanced and inclined, on the frame body to a level balance state, and level calibration action is efficient, fast and convenient.

Description

technical field [0001] The invention relates to a detection reference platform for detecting the machining accuracy of parts in mechanical processing, in particular to a precision detection platform for small parts. Background technique [0002] In mechanical processing, in order to meet the requirements of use, the processed parts need to be tested for processing accuracy such as flatness, verticality, and microscopic surface texture. Among them, small precision parts are the most common. The various processing accuracy inspections of the aforementioned small parts are mainly realized through the inspection platform, that is, the processed parts are placed on the inspection platform, and the reference positioning of the parts is formed through the inspection platform, and then the corresponding inspection device is used to realize the corresponding processing accuracy inspection. The detection accuracy of this detection method depends to a large extent on the horizontal c...
