Long and thin column glass rod clamping device

Abstract

The invention discloses a long and thin column glass rod clamping device which comprises a clamp, wherein the clamp is mounted on a clamping fixing jig; the clamping fixing jig is mounted on a fixingbase; the clamp comprises an integral bracket; a plurality groups of guide grooves are formed in the integral bracket; single-side clamping blocks and double-side clamping blocks are placed inside theguide grooves; the single-side clamping blocks and the double-side clamping blocks cooperate to clamp optical lenses; tetrafluorohydrazine pads on the single-side clamping blocks are connected with bottom ends of fixing screws; the fixing screws penetrate through the integral bracket; the integral bracket is connected with the clamping fixing jig; the clamping fixing jig comprises a fixing platefor fixing the integral bracket; a plurality groups of elastic pieces are arranged corresponding to the clamp on the fixing plate; the elastic pieces are used for constantly pressing the single-side clamping blocks and the double-side clamping blocks through compression springs; bulges on the back sides of the elastic pieces are clamped in long stripy holes of elastic plates; the elastic plates are hinged with rotating shifting forks; the rotating shifting forks are used for enabling the plurality groups of the elastic pieces to be lifted up simultaneously and be dissociated from top-layer single-side clamping blocks through cooperation of a pressing plate and the elastic plate. By adopting the device, automatic assembling and clamping can be achieved.

Description

technical field [0001] The invention belongs to the technical field of automatic production of optical lenses, and in particular relates to a clamping device for elongated cylindrical glass rods. Background technique [0002] In the pre-installation process of optical lens coating, it is required to fix the optical lens in the fixture according to the process requirements. At present, the clamping of the optical lens is completely operated manually, and the used fixture is vacuum coated for a long time in a high temperature environment, which is prone to Warping deformation does not meet the requirements for automatic card loading. There is no clamping device capable of automatically controlling the optical lens in the prior art. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a clamping device for elongated cylindrical glass rods, which can realize automatic clamp...
