Compressor lower cover form and position tolerance measuring instrument

Abstract

The invention discloses a compressor lower cover form and location tolerance measurement instrument. A locating disk is arranged on a base, a vertical column is connected with a guide plate, a plunger of a first air cylinder penetrates through the guide plate upward to be connected with a first connecting plate, and a front guide column and a rear guide column stretch to the base. A pressing rod assembly is arranged on a second connecting plate, a hanging plate is connected with a U-shaped block, a wall thickness measuring head penetrates through the U-shaped block to be installed on a sliding block, and a wall thickness measuring part is installed at the end of a measuring part rod. A supporting frame is arranged on the outer side of the locating disk for installation of an outer-diameter measuring head, an outer-diameter measuring part is arranged at the front end of the outer-diameter measuring head, an air inlet is formed in the rear end of the outer-diameter measuring head to be connected with an air supplying pipeline, an axial hole is formed in the center of the locating disk, an inner-diameter measuring seat is arranged in the axial hole, a spraying nozzle is arranged at the front end of the inner-diameter measuring seat, and an air inlet is formed in the rear end of the inner-diameter measuring seat to be connected with the air supplying pipeline. When a lower cover to be measured is placed in, the wall thickness measuring head, the outer-diameter measuring head and the inner-diameter measuring seat respectively measure corresponding data to be input into a processor to be compared with a standard block, and form and location tolerance is calculated and displayed onto a screen. The compressor lower cover form and location tolerance measurement instrument is easy and convenient to operate in the whole operating process, overcomes the defects existing in the current manual measurement and is suitable for detecting parts on a large scale one by one.

Description

technical field [0001] The invention is a tool for detecting the outer circle diameter, wall thickness, shaft hole diameter and relative position of the lower cover of the refrigerator and air conditioner compressor, in particular, it is a shape and position tolerance measuring instrument for the lower cover of the compressor. Background technique [0002] The turning process of the lower cover of the compressor involves the quality requirements of the relative position between the structures, such as shape and position tolerances such as concentricity and verticality. The conventional measurement method is to manually measure and calculate with the inner and outer diameter calipers according to the three coordinates. It takes 3-5 minutes to measure a single piece, which cannot meet the quality control during mass production. Contents of the invention [0003] Aiming at the defects existing in the prior art, the present invention proposes a shape and position tolerance mea...
