Detailed Description

Reference will now be made in detail to various exemplary embodiments of the utility model, the detailed description should not be construed as limiting the utility model but as a more detailed description of certain aspects, features and embodiments of the utility model.

It will be apparent to those skilled in the art that various modifications and variations can be made in the specific embodiments of the present disclosure without departing from the scope or spirit of the disclosure. Other embodiments will be apparent to those skilled in the art from consideration of the specification. The specification and examples are exemplary only.

The utility model provides a prism pressing tool, and is shown in figure 1 as a structural schematic diagram. In the embodiment of this pressfitting frock, this pressfitting frock includes: a base plate 1 and a pressure plate 2. Wherein, set up on the bottom plate 1 and treat fixed prism subassembly 3, prism subassembly 3 includes: a fixed seat 31 and a prism 32. Wherein, the prism 32 is put into the fixed seat 31 and coated with glue to form the prism assembly 3.

The pressing plate 2 is arranged on the prism component 3 and used for pressing the prism component 3 until the glue coating of the prism component 3 is completely cured, and the pressing of the prism component 3 can be realized. In addition, the lower bottom surface of the pressure plate 2 is a flexible surface for protecting the prism assembly 3, i.e., the surface of the prism 32, from being damaged. Specifically, the platen 2 includes an upper platen 22 and a lower platen 23. The lower pressing plate 23 is fixed to the lower portion of the upper pressing plate 22 by a fixing member, preferably, a bolt and a screw.

In the specific embodiment, the upper pressing plate 22 is made of a metal material, and the weight of the upper pressing plate is the pressure required by the prism assembly 3 for pressing, so as to provide a pressing force for the prism assembly. The pressing by the self-weight of the upper press plate 22 is to avoid that the pressing force is too large or too small during hydraulic or manual pressing, and the pressing force with uniform magnitude cannot be applied. The pressing is carried out by utilizing the dead weight of the pressing plate 2, so that the size of the pressing force in the pressing process can be kept unchanged until the glue is completely cured.

In the embodiment, the lower pressing plate 23 is made of a flexible material, and preferably, the lower pressing plate 23 is made of a polyurethane material. When the prism assembly 3 is pressed, the lower bottom surface of the lower pressing plate 23 made of flexible material contacts the surface of the prism 32, and the surface of the prism 32 can be protected from being damaged in the process of pressing the prism 32.

In the embodiment of the present invention, the bottom plate 1 has a plurality of guide posts 11, and the pressing plate 2 has a corresponding number of guide holes 21, and the positions thereof are corresponding.

In addition, the guide posts 11 are matched with the guide holes 21 and used for limiting the pressing moving direction of the pressure plate 2 and ensuring that the pressure plate 2 moves up and down in the direction vertical to the bottom plate 1. Specifically, the positions of the guide holes 21 on the upper pressure plate 22 and the lower pressure plate of the pressure plate 2 correspond to each other, so that the guide posts 11 are not blocked when passing through the guide holes 21 on the upper pressure plate 22 and the lower pressure plate 23, and the upward moving and downward pressing processes of the pressure plate 2 are ensured to be smoother.

In a specific implementation, the guide posts 11 are disposed at the sides or corners of the bottom plate 1, and the guide holes 21 are disposed on the pressure plate 2 at positions corresponding to the guide posts 11. In this embodiment, guide posts 11 are provided at four corners of the base plate 1. Correspondingly, there are only four guide holes 21 at the four corners of the platen 2.

In the embodiment of the present invention, as shown in fig. 2, the upper surface of the base plate 1 has a plurality of grooves 12 for placing the prism assembly 3. In specific implementation, the fixing seat 31 of the prism assembly 3 is placed in the groove 12, the prism 32 is arranged on the fixing seat 31, and the pressing plate 2 moves downwards along the guide post 11 until the pressing plate is pressed on the upper surface of the prism 32.

In the embodiment of the present invention, the lower bottom surface of the pressing plate 2 corresponds to the upper end surface of the base plate 1 in size. That is, the shape and area of the lower bottom surface of the pressing plate 2 correspond to the shape and area of the upper end surface of the base plate 1, so that the pressing plate 2 can cover the prism assembly 3 on the pressing base plate 1.

When in use, the prism 32 is firstly arranged on the fixed seat 31 and is glued. The glued prism assembly 3 is placed into the recess 12 in the upper surface of the base plate 1. After the prism assembly 3 is placed in the grooves 12 on the upper surface of the base plate 1, the flexible lower pressing plate 22 of the pressing plate 2 is arranged below and moves downwards until the prism assembly is pressed on the surface of the prism 32 according to the matching limit of the guide posts 11 and the guide holes 21. The upper pressing plate 21 made of metal compresses the prism assembly 3 by using the self-weight until the glue is completely cured. And finally, moving the pressing plate 2 upwards, and sequentially taking out the plurality of prism assemblies 3 which are pressed on the bottom plate 1.

The foregoing is merely an illustrative embodiment of the present invention, and any equivalent changes and modifications made by those skilled in the art without departing from the spirit and principle of the present invention should fall within the protection scope of the present invention.
