A cover plate pressure maintaining device

Abstract

The invention discloses a cover plate pressure-maintaining device, which comprises a bottom plate, a cover plate, a clamping device, a pressing device, a compressing device and a fool-proof device, wherein the cover plate is movably arranged on the surface of the bottom plate and is hinged to the bottom plate, the clamping device is fixed on the surface of the bottom plate, the pressing device is arranged in a coverage area of the cover plate, the compressing device is fixed on the lower surface of the cover plate and is arranged corresponding to the position of the pressing device, the fool-proof device is arranged beside the clamping device, the fool-proof device comprises a sleeve, a first fool-proof connecting block, a first elastic piece and a sensor, the sleeve is fixed on the bottom plate, the first fool-proof connecting block is accommodated in the sleeve, the first elastic piece supports the first fool-proof connecting block, and the sensor supports the first elastic piece. The cover plate pressure-maintaining device can achieve the compressing and pressure-maintaining actions of a flexible product in a local small space, has a fool-proof function, and can automatically judge whether the press-fit of the cover plate is in place correctly.

Description

【Technical field】 [0001] The invention belongs to the technical field of detection fixtures, in particular to a cover plate pressure maintaining device. 【Background technique】 [0002] In the manufacturing process of many products, it is necessary to test its function. Among them, there is a product that needs to be pressed and held for a certain period of time to complete the testing work. Because it needs to be tested together with other various tests As well as the characteristics of the product's own shape, the design of the pressing structure of the part to be pressed is limited to a small part, and the design is more difficult; and the pressing action needs to be maintained for a certain period of time, which further increases the difficulty of the design; the detection operation requires the product After the test is over, it can be easily taken out. [0003] Therefore, it is necessary to provide a cover pressure maintaining device to solve the above problems. 【Con...
