Description

Technical Field

[0001] This utility model belongs to the field of optical testing, and more specifically, it relates to a general-purpose circular optical lens testing fixture. Background Technology

[0002] Circular optical lenses have a wide range of applications. During the manufacturing process, various parameters of circular optical lenses need to be tested. Because different circular optical lenses have different sizes, there is no universal tooling fixture for testing, making testing inconvenient. Therefore, it is necessary to design a universal testing fixture for circular optical lenses to facilitate testing. Utility Model Content

[0003] This invention proposes a universal testing fixture for circular optical lenses, which solves the problem that existing circular optical lenses have different sizes and there is no universal fixture for testing, making it inconvenient.

[0004] The technical solution of this utility model is implemented as follows:

[0005] A general-purpose circular optical lens testing fixture includes a base plate that can be attracted by a magnet. Two magnetic bases that can adjust the distance between each other are arranged on the base plate. Each magnetic base is fixed with an inclined support block. The inclined support block includes an inclined surface with an angle of 45° with the horizontal direction. An isosceles trapezoidal clamping groove with a larger top and a smaller bottom is formed between the two inclined surfaces.

[0006] Preferably, the base plate is a horizontal steel plate.

[0007] Preferably, the magnetic base includes a soft magnetic material base with a horizontal cylindrical hole in the middle. A cylinder is rotatably fitted inside the cylindrical hole, and a strip-shaped permanent magnet or constant magnet is fixedly fitted inside the cylinder.

[0008] Preferably, a knob is fixed to the outer end of the cylinder.

[0009] Preferably, the inclined support block includes a horizontal plate and an inclined plate, the inclined plate is fixed to one end of the horizontal plate, the inclined surface is located on the inclined plate, and the horizontal plate is fixed to the upper surface of the magnetic base by fixing screws.

[0010] Preferably, the bottom of the inclined support block is provided with a limiting slot that cooperates with the magnetic base.

[0011] Preferably, the limiting groove is an L-shaped groove or a U-shaped groove.

[0012] The beneficial effects of this invention are as follows: In use, rotating the cylinder via the knob rotates the magnet inside the cylinder. When the two poles of the magnet (N and S poles) are in the horizontal direction, and the center of N and S poles is directly opposite the soft magnetic material base (the center of the long bar magnet has very little magnetism and can be ignored), it will not be magnetized. Therefore, there is almost no magnetic force on the soft magnetic material base, and it can be easily removed from the base plate surface. Adjusting the distance between the two magnetic bases, that is, adjusting the distance between the two inclined support blocks, can accommodate circular optical lenses of different sizes. After adjustment, rotating the cylinder again, when the two poles of the magnet (N or S) are in the vertical direction, that is, when the N or S pole of the magnet is directly opposite the soft magnetic material base, the soft magnetic material base is magnetized. This direction has a strong magnetism, so it can be used to attract the base plate surface to achieve a fixing effect. Finally, the circular optical lens is placed between the two inclined support blocks, and the circumferential surface of the circular optical lens contacts the inclined surface on the inclined support block. Under the action of its own weight, the circular optical lens stands between the inclined support blocks and will not fall forward or backward. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-2 A general-purpose circular optical lens testing fixture includes a base plate 1 that can be attracted by a magnet. Two magnetic bases 2 that can adjust the distance between them are arranged on the base plate 1. An inclined support block 3 is fixed on each of the magnetic bases 2. The inclined support block 3 includes an inclined surface 31 with an angle of 45° to the horizontal direction. An isosceles trapezoidal clamping groove 4 with a larger upper surface and a smaller lower surface is formed between the two inclined surfaces 31.

[0024] The base plate 1 can be a horizontal steel plate or other metal plates that can be attracted by a magnet.

[0025] The magnetic base 2 includes a soft magnetic material base 21, with a horizontal cylindrical hole 22 in the middle of the soft magnetic material base 21. A cylinder 23 is rotatably fitted inside the cylindrical hole 22, and a strip-shaped permanent magnet or constant magnet (not shown) is fixedly fitted inside the cylinder 22.

[0026] To facilitate rotation, a knob (not shown) can be fixed to the outer end of the cylinder 23.

[0027] The inclined support block 3 includes a horizontal plate 32 and an inclined plate 33. The inclined plate 33 is fixed to one end of the horizontal plate 32, and the inclined surface 31 is located on the inclined plate 33. The horizontal plate 32 is fixed to the upper surface of the magnetic base 2 by fixing screws (not shown).

[0028] The inclined support block 3 has a limiting groove 34 at its bottom that cooperates with the magnetic base 2. The limiting groove 34 is an L-shaped groove or a U-shaped groove.

[0029] In use, rotating the cylinder 22 via the knob rotates the magnet inside the cylinder 22. When the two poles of the magnet (N and S poles) are horizontal, and the center of N and S poles is directly opposite the soft magnetic material base 21 (the center of the long bar magnet has very little magnetism and can be ignored), it will not be magnetized. Therefore, there is almost no magnetic force on the soft magnetic material base 21, and it can be easily removed from the surface of the base plate 1. Adjusting the distance between the two magnetic bases 2, that is, adjusting the distance between the two tilting support blocks 3, allows for the use of circular optical lenses 5 of different sizes. After the joint is completed, rotate cylinder 22. When the two poles (N or S) of the magnet are in the up-down direction, that is, when the N or S pole of the magnet is facing the soft magnetic material base 21, the soft magnetic material base 21 is magnetized. It has a strong magnetism in this direction, so it can be used to hold the surface of the base plate 1 to achieve a fixed function. Finally, place the circular optical lens between the two inclined support blocks 3. The circumferential surface of the circular optical lens 5 contacts the inclined surface 31 on the inclined support block 3. The circular optical lens 5 stands between the inclined support blocks 3 under its own weight and will not fall forward or backward.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
