Description

Technical Field

[0001] The utility model relates to a cylindrical mirror processing and forming jig. Background Art

[0002] The cylindrical mirror is an aspherical lens that can effectively reduce spherical aberration and chromatic aberration and has a one-dimensional magnification function. The processing of cylindrical mirror parts usually goes through stages such as rough grinding, fine grinding, and grinding.

Existing fixtures, such as the cylindrical mirror processing fixture disclosed in the Chinese utility model patent specification CN 209239711U, can meet the clamping requirements when processing cylindrical mirror parts. This fixture consists of two clamping blocks. When clamping the meniscus cylindrical mirror, the middle concave cylindrical surface of the bottom surface of the cylindrical mirror is suspended in the air, lacking support, and has poor stability and firmness.

[0013] The present application scheme is further described below in conjunction with the accompanying drawings.

[0014] like Figures 1 to 5 A cylindrical mirror processing and forming jig is shown, the cylindrical mirror 10 is a meniscus cylindrical mirror, including a bottom surface, a top surface 101 opposite to the bottom surface, and a side surface connected between the bottom surface and the top surface 101, the top surface 101 is a convex cylindrical surface, the bottom surface includes a middle concave cylindrical surface 102 and bottom planes 103 located on both sides of the middle concave cylindrical surface 102, the side surface includes two opposite side planes 104 extending along the axial direction of the cylindrical mirror, and the cylindrical mirror processing and forming jig includes a jig body 20 in the shape of a rectangular parallelepiped;

[0015] The middle part of the fixture body 20 is provided with a plurality of bosses 30 for supporting the middle concave cylindrical surface 102 of the bottom surface of the cylindrical mirror. All bosses 30 are arranged at intervals along the length direction of the fixture body 20. The top surface 301 of each boss is a convex cylindrical surface that fits with the middle concave cylindrical surface 102. The bosses shown in the figure in this embodiment are cylindrical.

[0016] A plurality of columns 40 for supporting the bottom plane 103 of the bottom surface of the cylindrical mirror are respectively provided on both sides of the fixture body 20, and the top surface 401 of each column is an end plane that fits the bottom plane 103;

[0017] Among the columns 40 on the same side, all the columns 40 are arranged at intervals along the length direction of the fixture body 20, and the columns 40 and the bosses 20 are staggered in the length direction of the fixture body 20, which can improve the stability and firmness of supporting the cylindrical mirror.

[0018] This technical solution can respectively support the middle concave cylindrical surface and the bottom plane of the bottom surface of the cylindrical mirror by arranging spaced bosses and columns, thereby ensuring the stability of clamping while meeting the processing and forming requirements of the cylindrical mirror and saving materials.

[0019] The top surface 401 of each column is provided with a side stopper 402 for the side plane 104 of the cylindrical mirror to abut against. The side stopper can be used to position the cylindrical mirror and also to limit the position of the cylindrical mirror on the width of the fixture body to avoid dislocation during processing.

[0020] The height of each side stopper 402 is smaller than the thickness of the cylindrical mirror 10 to prevent the side stopper from hindering the processing of the top surface of the cylindrical mirror.

[0021] The clamping process of the fixture disclosed in the utility model is as follows: first, wax for bonding the cylindrical mirror is applied on the top surface of each boss and the top surface of each column, and then the cylindrical mirror is placed, the two side surfaces of the cylindrical mirror are respectively against the side block on the same side, the middle concave cylindrical surface of the bottom surface of the cylindrical mirror is fitted with the top surface of the boss, and the two bottom planes of the bottom surface of the cylindrical mirror are respectively fitted with the top surface of the column on the same side, and the clamping is completed after the wax solidifies.
