Second rotating shaft group of three-axis linked large circuit board testing fixture

Abstract

The invention discloses a second rotating shaft group of a three-axis linked large circuit board testing fixture. The second rotating shaft group of the three-axis linked large circuit board testing fixture comprises a second rotating shaft, a front second rotating shaft bevel gear, a back second rotating shaft bevel gear, upper second rotating shaft pressing pieces and lower second rotating shaft pressing pieces; the two ends of the second rotating shaft are mounted on a universal base plate by use of rotating shaft seats; the front second rotating shaft bevel gear and the back second rotating shaft bevel gear are mounted on the two end portions of the second rotating shaft, respectively; the back second rotating shaft bevel gear is engaged with a first rotating shaft bevel gear; two upper second rotating shaft pressing pieces are arranged between the two rotating shaft seats of the second rotating shaft, and the corresponding lower second rotating shaft pressing pieces are arranged on the lower parts of the upper second rotating shaft pressing pieces; the upper second rotating shaft pressing pieces and the lower second rotating shaft pressing pieces are locked to the second rotating shaft by use of screws. In this way, the second rotating shaft group of the three-axis linked large circuit board testing fixture is simple and practical in structure, convenient to detect and repair, and capable of effectively clamping and positioning a large-scale circuit board.

Description

technical field [0001] The invention relates to the field of testing fixtures, in particular to a second rotating shaft group of a three-axis linkage type large circuit board testing fixture. Background technique [0002] In modern industrial manufacturing, especially in the detection and assembly of electronic products, a lot of labor is required to complete various complex workflows, which brings a lot of human interference to the overall assembly line production operations, and large-scale It is not very convenient to handle and inspect the large circuit boards required in the production of electrical appliances. Ordinary manual clamps often cannot clamp and position stably and effectively, or clamping deviation occurs. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a second rotating shaft group of a three-axis linkage large-scale circuit board test fixture, which has a simple and practical structure, conven...
