Description

Technical Field

[0001] The utility model relates to the technical field of prism pasting, in particular to a prism pasting fixture. Background Art

[0002] As Figure 1 shown, in the processing of existing prisms, multiple prisms 1 need to be fixed by wax pasting for batch processing operations. During the process of pasting multiple prisms together, it is necessary to ensure that the wax between the multiple prisms is of an appropriate amount. Too much or too little wax will affect the processing of subsequent processes.

[0003] Currently, the wax discharging after prism pasting is achieved by stacking multiple prisms in layers and having an operator press the upper pressing plate of the prism by hand. The excess wax between the multiple prisms is discharged by the downward extrusion of the upper pressing plate. However, manual operation has the following technical defects:

[0004] 1. When pressing the prism by hand, since the operator cannot master the pressing force well, too much force is likely to result in too little wax between the prisms, and scratches will occur in the subsequent processing.

[0005] 2. When pressing the prism by hand, the force applied at both ends of the prism will be uneven, resulting in a height difference, and there will be a problem with the straight angle after wire cutting. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model designs a prism pasting fixture.

[0007] The utility model adopts the following technical solutions:

[0008] A prism pasting fixture includes a fixture body. The fixture body includes two right-angle frames, two crossbars, and a cover plate. The two right-angle frames are fixedly connected by the two crossbars. The right-angle frame is composed of two support columns and a support crossbeam. The two ends of the support crossbeam are connected to the two support columns. Positioning columns are arranged above each support column. Positioning slots are respectively opened at the four corners of the cover plate corresponding to the positioning columns. The cover plate moves down along the positioning columns through the positioning slots until it reaches the root of the positioning columns, and the root of the positioning columns is used for limiting the cover plate.

[0009] Preferably, two downwardly convex pressing strips are arranged in parallel at the bottom of the cover plate, and the lower surface of the pressing strip is a flat surface.

[0010] Preferably, the upper surface of the cover plate is a flat surface, which is used for placing a downward pressing heavy object.

[0011] Preferably, the two support columns and the support crossbeam are fixed by inserting and clamping.

[0012] Preferably, the two ends of the two crossbars are respectively fixedly connected to the two right-angle frames by bolts passing through bolt holes.

[0013] Preferably, a relief hole is provided in the positioning groove on the cover plate.

[0014] The beneficial effects of the present utility model are as follows: The present utility model designs a prism pasting fixture, which facilitates the flat pressing of multiple stacked prisms after they are placed in the fixture body. The pressing height is restricted by the positioning groove and the positioning post, ensuring that the wax between multiple prisms after dewaxing has an appropriate amount. At the same time, the two ends of the prism are evenly stressed and there will be no height difference, improving the yield rate of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:

[0021] Embodiment: As Figures 2 - 4 shown, a prism pasting fixture includes a fixture body. The fixture body includes two right-angle frames 2, two cross bars 3, and a cover plate 4. The two right-angle frames are fixedly connected by the two cross bars. The right-angle frame is composed of two support columns 5 and a support cross beam 6. The two ends of the support cross beam are connected to the two support columns. Positioning posts 8 are provided above each support column. Positioning grooves 9 are respectively provided at the four corners of the cover plate corresponding to the positioning posts. The cover plate moves down along the positioning posts through the positioning grooves until the roots of the positioning posts. The roots of the positioning posts are used for limiting the cover plate.

[0022] Two pressing strips 10 are convexly provided in parallel at the bottom of the cover plate. The lower surface of the pressing strip is a flat surface. The upper surface of the cover plate is a flat surface for placing a pressing weight for vertical pressing. The two support columns and a support cross beam are fixedly connected by inserting and clamping.
