Abstract
The invention discloses a using method of a tri-axial linkage type large circuit board test fixture. The using method comprises the steps that firstly, a self-locking hook is released, an opening hand lever is lifted upwards, a first rotary shaft bevel gear of a first rotary shaft set rotates and drives a second rotary shaft rear bevel gear of a second rotary shaft set to rotate, and a second rotary shaft front bevel gear of the second rotary shaft set rotates and drives a third rotary shaft bevel gear of a third rotary shaft set to rotate; secondly, the first rotary shaft set, the second rotary shaft set and the third rotary shaft bevel gear drive a first rotary shaft upper pressing piece, a second rotary shaft upper pressing piece and a third rotary shaft upper pressing piece to overturn upwards at the same time in the rotating process, and a large circuit board is placed on a carrier in the middle of a universal bottom plate at the time; thirdly, the opening hand lever is laid down slowly, all the rotary shaft sets rotate reversely under the action of a press fitting spring roll strip, and the large circuit board is pressed and positioned through all the rotary shaft upper pressing pieces; fourthly, the opening hand lever slides over the top end slope of the self-locking hook and is locked. In this way, the tri-axial linkage type large circuit board test fixture is simple in structure, practical and capable of effectively clamping and positioning the large circuit board.
Description
Technical field
The present invention relates to fitting device field, particularly relate to a kind of using method of three-shaft linkage formula large scale circuit board test fixture.
Background technology
During in modern industry is manufactured, especially the detection of electronic product and assembling are produced, what needs were a lot of manually completes various complex work flow processs, so overall streamline production operation is brought the interference of a lot of human factors, and its required large scale circuit plate carrying and to detect be not very convenient in the production of large electric appliances, common manual often cannot be stablized effective clamping position, or occurs the phenomenons such as clamping skew.
Summary of the invention
The technical matters that the present invention mainly solves is to provide a kind of using method of three-shaft linkage formula large scale circuit board test fixture, and it is simple and practical, detects easy to maintenancely, can effectively carry out clamping position to large scale circuit plate.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: the using method that a kind of three-shaft linkage formula large scale circuit board test fixture is provided, its using method is: the first step is unclamped Self-locking hanging hook, upwards lift unlatching hand lever, the first rotating shaft umbrella tooth of the first rotating shaft group rotate and drive the second rotating shaft of the second rotating shaft group after umbrella tooth rotate, before the second rotating shaft of the second rotating shaft group, umbrella tooth rotates and drives the 3rd rotating shaft umbrella tooth of the 3rd rotating shaft group to rotate, second step is when the first rotating shaft group, the second rotating shaft group and the 3rd rotating shaft group can drive compressing tablet in the first rotating shaft while rotation simultaneously, in the second rotating shaft, in compressing tablet and the 3rd rotating shaft, compressing tablet upwards overturns, now large scale circuit plate is placed on the middle bracket of common bottom plate, the 3rd step is slowly put down unlatching hand lever, each rotating shaft group rotates backward under the effect that press-fits spring volume bar, and drive compressing tablet in the first rotating shaft, in the second rotating shaft, in compressing tablet and the 3rd rotating shaft, location pushed down by large scale circuit plate by compressing tablet upset downwards, the 4th step is opened hand lever and is slipped over the inclined-plane, top of Self-locking hanging hook and pin.
The invention has the beneficial effects as follows: the using method of three-shaft linkage formula large scale circuit board test fixture of the present invention, it is simple and practical, detects easy to maintenancely, can effectively carry out clamping position to large scale circuit plate.
