Tri-axial linkage type large circuit board test fixture

Abstract

The invention discloses a tri-axial linkage type large circuit board test fixture. The tri-axial linkage type large circuit board test fixture comprises a universal bottom plate, a press fitting spring roll strip, an opening hand lever, a self-locking hook, a first rotary shaft set, a second rotary shaft set, a third rotary shaft set and bevel gear protection cover pieces, wherein the first rotary shaft set, the second rotary shaft set and the third rotary shaft set are sequentially connected in a meshing and perpendicular intersection mode; the bevel gear protection cover pieces are arranged at the meshing positions respectively; the first rotary shaft set, the second rotary shaft set and the third rotary shaft set are all installed on the universal bottom plate through rotary shaft seats; the opening hand lever is arranged at the non-meshing end of the first rotary shaft set; the press fitting spring roll strip is arranged on the first rotary shaft set close to the right side of the opening hand lever; the end of the outer ring of the press fitting spring roll strip is fixed to the universal bottom plate; the self-locking hook locking the opening hand lever is arranged on the opening hand lever close to the non-meshing position of the third rotary shaft set. In this way, the tri-axial linkage type large circuit board test fixture is simple and practical in structure, convenient to detect and maintain, and capable of effectively clamping and positioning a large circuit board.

Description

technical field [0001] The invention relates to the field of testing fixtures, in particular to 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 three-axis linkage type large-scale circuit board test fixture, which has a simple and practical structure, convenient detection and maintenance, and can effectively clamp and...
