Description

Technical Field

[0001] This utility model belongs to the field of optical inspection. Specifically, it relates to an adjustable distance tooling fixture for inspecting the size of a product on a polishing disc. Background Technology

[0002] Optical products have a wide range of applications, and the polishing process is particularly crucial in their manufacturing. In the polishing process, products need to be fixed to a polishing pad using optical adhesive or cold adhesive. Process planners select different sized polishing pads based on order volume. However, existing inspection processes have significant bottlenecks: traditional testing stands use a fixed-distance design, which cannot accommodate polishing pads of different sizes—especially large-sized pads with bases, requiring manual measurement using a micrometer. This measurement method has two drawbacks: first, it requires measuring the optical adhesive pad and the product together, then indirectly determining the product size through complex calculations, which is inefficient and prone to errors; second, the outer edge of the optical adhesive pad wears down due to repeated use, directly affecting measurement accuracy. Therefore, there is an urgent need to develop an adjustable-distance, on-pad measurement fixture. The use of this fixture will greatly improve inspection efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a tooling fixture for detecting the adjustable distance of the product size on the polishing pad, including a base (8), on which a fixed support rod (1) is placed. Next to the fixed support rod (1) is a three-jaw chuck (9) for adjusting the position. The three-jaw chuck (9) includes three guide rails (10) that are at a 120-degree angle to each other. Three sliding jaws (7) that can slide along the rail direction are placed in the middle of the guide rails (10). The three sliding jaws (7) can be fixed on the guide rails (10). There are scaled steel rulers (6) on both sides of the guide rails (10) for adjusting the coordinates of the sliding jaws (7). Above the steel ruler is placed a... A test head is provided; the test head includes a power supply device (11), a digital display screen (12) is provided in front of the power supply device (11), the digital display screen (12) is used to read the thickness of the product, the surface of the digital display screen (12) is provided with zeroing and power on / off buttons (13), a test probe (14) is provided below the power supply device (11), the sensor at its tip is used to determine the position of the product, the test head is placed on the head bracket (3) through the head position hole (5) and fixed by the knob (4) on the side of the head bracket (3), the head bracket (3) is placed on the fixed support rod (1) and tightened by the height adjustment knob (2) on the side.

[0004] Furthermore, the three-jaw chuck (9) includes three guide rails (10) that are at a 120-degree angle to each other. Three sliding jaws (7) that can slide along the rail direction are placed in the middle of the guide rails (10). The surface of the guide rails (10) is smooth, so that the three jaws placed on the guide rails can slide freely along the guide rails to provide enough space to place the measuring product.

[0005] Furthermore, there are graduated steel rulers (6) on both sides of the guide rail (10) to adjust the coordinates of the sliding jaws (7). The steel rulers are used to determine the position of the product on the guide rail (10). The three sliding jaws (7) move along the guide rail and their positions can be observed in real time. The three radii with an included angle of 120° together form a circle, so that the product can be placed in the center of the triangular chuck.

[0006] Furthermore, the test head includes a test head power supply device (11), which is connected to a power source to control the on / off state of the test device. A digital display screen (12) is provided in front of the test head power supply device (11), and the digital display screen (12) is used to read the thickness of the product.

[0007] Furthermore, the digital display screen (12) is provided with a zeroing and power-on / off button (13). The zeroing and power-on / off button (13) mainly controls the conduction and disconnection of the circuit. When the circuit is on, pressing the zeroing and power-on / off button (13) again will reset the data on the digital display screen (12) to zero. This position is recorded as the measurement zero point.

[0008] Furthermore, a test probe (14) is provided below the power supply device (11) of the meter head. The sensor on its surface is used to determine the position of the product. The upper end of the test probe (14) is connected to the power supply device (11) of the meter head. The measured position information is directly transmitted to the power supply device (11). The calculation unit therein obtains the thickness data by comparing the position difference and presents it on the digital display screen (12).

[0009] Furthermore, the test head is placed on the head bracket (3) and fixed by the knob (4) on the side of the head bracket (3). Rotating the knob (4) can adjust the position of the head on the bracket.

[0010] Furthermore, the meter head bracket (3) is placed on the fixed support rod (1) and tightened by the height adjustment knob (2) on the side. By adjusting the height adjustment knob (2), the height of the meter head in the vertical direction can be adjusted, thereby enabling the detection of products of different heights. Using this fixture, polished products can be measured directly on the polishing disc without measurement failure due to the shape of the polishing disc.

[0011] The advantages of this utility model are: during the optical manufacturing process, it is necessary to test the product size on the grinding and polishing disc. During the test, the polishing disc can be placed directly on the sliding jaws (7). By adjusting the distance of the three sliding jaws (7), the size of the polishing disc to be tested can be adjusted to a suitable position for testing. There is no need to purchase multiple testing devices, and the process debugging is convenient and quick. Attached Figure Description
