DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-2As shown, the utility model provides a jig for detecting precision parts, which is mainly used to detect the surface finish of precision parts. The user only needs to place the precision parts to be tested on the testing table 2. By adjusting the positions of the testing table 2, the light source 3 and the lens 4, a better image of the parts to be tested can be collected to obtain better test results.

[0019] The structure of the fixture for detecting precision parts mainly includes a bracket 1, on which are installed a detection table 2 for placing parts, a light source 3 for projecting light to the detection table 2, and a lens 4 for collecting image information of parts on the detection table 2. Among them, the position for placing precision parts in the middle of the detection table 2 is a transparent structure, and the light source 3 is arranged below the detection table 2 and projects light toward the transparent structure in the middle of the detection table 2. At this time, the lens 4 is arranged above the detection table 2 to use the image of the precision parts. In addition, it should be noted that if there is insufficient light on one end of the lens 4 of the detection table 2, the lens 4 also needs to supplement the light projected to one end of the detection table 2.

[0020] Depending on the different precision parts, the position of the test bench 2 may need to be adjusted to obtain better test results. The test bench 2 is connected to the bracket 1 through two vertical poles 5. The vertical poles 5 pass through the interior of the test bench 2, so that the test bench 2 moves along the direction of the length of the vertical poles 5. The test bench 2 is also equipped with a locking member 6 that is locked with the vertical poles 5. The position of the test bench 2 can be adjusted by moving on the vertical poles 5, and finally locked with the vertical poles 5 by the locking members 6 on both sides to form a fixed height. In order to allow the test bench 2 to better allow the light source 3 to transmit light and obtain images of precision parts, a transparent plate 10 is installed at the position of the transparent structure in the middle of the test bench 2. The transparent plate 10 can be a glass plate, an acrylic plate, etc.

[0021] To better secure the test platform 2 to the uprights 5, downwardly projecting mounting portions 11 are provided at both ends of the test platform 2. These mounts 11 fit over the outsides of the uprights 5 to increase the contact area between the test platform 2 and the uprights 5. Correspondingly, multiple spiral grooves 12 are distributed along the outsides of the uprights 5 in the direction of movement of the test platform 2. The spiral grooves 12 on the two uprights 5 are aligned at the same height, ensuring that the test platform 2 remains horizontal after adjustment. To secure the test platform 2, the locking member 6 is inserted from the outside of the mounting portion 11 and screwed into the spiral groove 12 to secure the test platform 2 to the uprights 5.

[0022] The light source 3 that provides light is located below the inspection table 2. The light source 3 is connected to the bracket 1 via a first linear guide 7, allowing the light source 3 to move along the length of the first linear guide 7. Depending on whether the precision parts are placed at different positions on the inspection table 2, or if the precision parts are also of different sizes, it is necessary to adjust the position of the light source 3 to adjust the position of the light. During adjustment, the light source 3 moves on the first linear guide 7 and can be adjusted to different positions to project light.

[0023] To better adjust the position of the light source 3, a light source mounting plate 13 is added between the light source 3 and the first linear guide rail 7 to strengthen the mounting and fixing of the light source 3. The light source 3 is mounted on the top of the light source mounting plate 13, and the bottom of the light source mounting plate 13 is connected to the first linear guide rail 7. The light source 3 is moved by the light source mounting plate 13 on the first linear guide rail 7, thereby achieving the effect of adjusting the light source 3. In addition, a light source adjustment cylinder 14 is also installed on the bracket 1, which drives and controls the movement of the light source mounting plate 13 on the first linear guide rail 7.

[0024] The lens 4 for collecting image information is arranged above the test platform 2. According to different precision parts, it is necessary to adjust the distance between the lens 4 and the test platform 2 to obtain a better collected image. The lens 4 is connected to a lens mounting plate 8, wherein one end of the lens mounting plate 8 is sleeved on the outside of the vertical pole 5, and the other end of the lens mounting plate 8 is connected to the bracket 1 through a second linear guide rail 9. The lens 4 is guided by the vertical pole 5 and the second linear guide rail 9 to move toward the test platform 2. The lens mounting plate 8 with the lens 4 installed, under the dual guidance of the vertical pole 5 and the second linear guide rail 9, ensures that the direction of movement of the lens 4 will not deviate, thereby improving the accuracy of the collection. It should be supplemented that when the lens 4 is in use, it needs to be used in conjunction with an external device to facilitate the user to view the collected results.

[0025] To control the movement of the lens 4 and adjust the distance from the detection platform 2, a lens adjustment cylinder 15 is installed on the top of the bracket 1. The output end of the lens adjustment cylinder 15 is connected to the lens mounting plate 8, which drives the lens mounting plate 8 to move on the second linear guide rail 9 to adjust the position of the lens 4.

[0026] Compared with traditional technologies, the fixture provided by this technical solution allows users to flexibly adjust the positions of the test table 2, light source 3 and lens 4 according to different precision parts during testing to better collect image information and improve the accuracy of the test results. The overall operation is simple, stable and flexible.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description.
