A foolproof device for testing crystal head

Abstract

This utility model relates to a crystal head testing and error-proofing device in the field of crystal head error-proofing technology. It includes a processing table with a rectangular hole. A rectangular plate is rotatably connected inside the rectangular hole via a pair of rotating shafts. When adjusting the angle of the crystal head, the moving frame must be manually pulled upwards to remove the lower end of the connector from the insertion slot. Simultaneously, the connector block pulls up a spring, causing it to be stretched further. Then, the rectangular plate is rotated up and down, causing the crystal head to rotate up and down as well, thereby adjusting the angle of the crystal head. After adjusting the angle, the external force applied to the moving frame is removed, causing the spring to pull the connector block, the moving frame, and the connector downwards together, allowing the lower end of the connector to be inserted into the corresponding insertion slot, thus fixing the rotating shaft and the rectangular plate. This application provides a simple and time-saving procedure for adjusting the crystal head, making it convenient for personnel to use when processing and testing crystal heads.

Description

Technical Field

[0001] This utility model relates to a crystal head testing error prevention device, and in particular to a crystal head testing error prevention device applied in the field of crystal head error prevention. Background Technology

[0002] Crystal clarity is a key indicator for evaluating the optical properties of crystal materials (such as transparency and refractive index). Its core function is to ensure the quality and functionality of crystal products in specific application scenarios. Crystal grades are distinguished by clarity tests, and high-quality materials that meet the high-precision requirements of optical devices and jewelry processing are selected. Crystals with low transparency or too many impurities are prevented from entering the production process. High clarity crystals can reduce light signal attenuation and improve the light transmission efficiency of devices such as lenses and prisms. Transparency and refractive index determine the luster and fire effect of gemstones and are the core basis for pricing.

[0003] When testing crystal crystal heads during production and processing, personnel use a crystal crystal head testing error-proof device. This device constrains the position of the crystal crystal head to avoid measurement errors caused by misalignment. The crystal crystal head testing error-proof device replaces manual judgment with technical constraints, blocking potential errors in crystal crystal head testing (such as misalignment, overpressure, and data confusion) at the source. It is suitable for quality control scenarios of high-precision and high-value crystal products.

[0004] Existing crystal head testing and error-proofing devices constrain and fix the position of the crystal head. When it is necessary to adjust the angle of the crystal head, it is usually necessary to remove it from the mechanism that constrains the crystal head on the crystal head testing and error-proofing device, then manually rotate the crystal head, and then put the crystal head back on the crystal head testing and error-proofing device and fix its position. Therefore, the operation steps for adjusting the angle of the crystal head are cumbersome and time-consuming, and it is inconvenient for personnel to use when processing and testing crystal heads. Utility Model Content

[0005] The technical problem to be solved by this utility model in view of the above-mentioned prior art is that the existing crystal head testing and error prevention device has a complicated and time-consuming operation procedure for adjusting the angle of the crystal head, which is inconvenient for personnel to use when processing and testing crystal heads.

[0006] To solve the above problems, this utility model provides a fault-proof device for testing the crystal head, including a processing table with a rectangular hole. A rectangular plate is rotatably connected to the inside of the rectangular hole via a pair of rotating shafts. A rectangular groove is formed at the upper end of the rectangular plate. An electric push rod is fixedly connected to a pair of inner sidewalls of the rectangular groove. A movable plate is fixedly connected to the telescopic end of the electric push rod. A movable frame is provided at the upper end of the processing table. Multiple plug-in blocks and a pair of plug-in pipes are fixedly connected to the lower end of the movable frame. Multiple plug-in slots are formed at the outer end of the rotating shafts, which are movably inserted into the plug-in pipes. Multiple sliding grooves are formed at the upper end of the processing table, which are slidably connected to the plug-in blocks. A spring is fixedly connected to the lower end of the plug-in block, and the lower end of the spring is fixedly connected to the inner bottom wall of the sliding groove.

[0007] In the above-mentioned crystal head testing error prevention device, the steps for adjusting the crystal head are relatively simple and time-saving, making it convenient for personnel to use when processing and testing crystal heads.

[0008] As a further improvement of this application, in the initial state, the lower end of the moving frame is in contact with the upper end of the processing table, and the spring is in a stretched state.

[0009] As a further improvement of this application, in the initial state, the lower end of the insertion tube passes through the processing table and is inserted into the inside of the insertion slot.

[0010] As a further improvement of this application, a pair of handles are fixedly connected to the upper end of the mobile frame, and there are gaps between the two side ends of the rectangular plate and the inner wall of the rectangular hole.

[0011] As a further improvement of this application, the outer end of the moving plate is slidably connected to the inner wall of the rectangular groove, and the upper end of the moving plate is flush with the upper end of the rectangular groove.

[0012] As another improvement of this application, a connecting plate is placed against the side of the moving plate, and a sponge plate is fixedly connected to the end of the connecting plate away from the moving plate. A connecting block is fixedly connected to the upper end of the connecting plate, and a limit tube is threadedly connected inside the connecting block. In the initial state, the lower end of the limit tube extends out from the connecting block and is threadedly connected to the inside of the moving plate.

[0013] As a further improvement to this application, a pair of reinforcing grooves are provided on the side end of the moving plate, and a pair of reinforcing strips that are movably inserted into the reinforcing grooves are fixedly connected to the end of the connecting plate away from the sponge board.

[0014] In summary, when adjusting the angle of the crystal head, the movable frame needs to be manually pulled upwards to remove the lower end of the connector from the connector slot, thereby releasing the connector's limiting effect on the rotating shaft. Simultaneously, the connector block will pull the spring upwards, allowing it to continue being stretched. Then, the rectangular plate will be rotated up and down, causing the crystal head to rotate up and down together, thus adjusting the angle of the crystal head. After adjusting the angle of the crystal head, the external force applied to the movable frame is removed, causing the spring to pull the connector block, movable frame, and connector downwards together, allowing the lower end of the connector to be inserted into the corresponding connector slot, thus fixing the rotating shaft and the rectangular plate. In use, the steps for adjusting the crystal head are relatively simple and time-saving, making it convenient for personnel to use when processing and testing crystal heads.

Detailed Implementation

[0022] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0023] First implementation method:

[0024] Figure 1-5A fault-prevention device for testing crystal head is shown, including a processing table 1. A rectangular hole 2 is provided on the processing table 1. A rectangular plate 4 is rotatably connected to the inside of the rectangular hole 2 through a pair of rotating shafts 3. A rectangular groove 5 is provided at the upper end of the rectangular plate 4. The crystal head in the rectangular groove 5 has a certain protective function, which makes it difficult for the crystal head to fall off the rectangular plate 4. An electric push rod 6 (model XX-S) is fixedly connected to a pair of inner side walls of the rectangular groove 5. A movable plate 7 is fixedly connected to the telescopic end of the electric push rod 6. A movable frame 8 is provided at the upper end of the processing table 1. A plurality of plug-in blocks 9 and a pair of plug-in pipes 10 are fixedly connected at the lower end of the movable frame 8. A plurality of plug-in slots 11 are provided at the outer end of the rotating shaft 3, which are movably inserted into the plug-in pipes 10. A plurality of sliding grooves 13 are provided at the upper end of the processing table 1, which are slidably connected to the plug-in blocks 9. A spring 12 is fixedly connected at the lower end of the plug-in block 9. The lower end of the spring 12 is fixedly connected to the inner bottom wall of the sliding groove 13.

[0025] In the initial state, the lower end of the movable frame 8 is in contact with the upper end of the processing table 1, the spring 12 is in a stretched state, and the lower end of the insertion tube 10 passes through the processing table 1 and is inserted into the insertion slot 11.

[0026] A pair of handles are fixedly connected to the upper end of the movable frame 8. There is a gap between the two side ends of the rectangular plate 4 and the inner wall of the rectangular hole 2. The outer end of the movable plate 7 is slidably connected to the inner wall of the rectangular groove 5. The upper end of the movable plate 7 is flush with the upper end of the rectangular groove 5.

[0027] The application is used in the following steps:

[0028] Step 1: When processing and testing the crystal head, it needs to be placed in the rectangular groove 5. Then, start the electric push rod 6 to make the moving plate 7 close to the crystal head and apply force to both sides to constrain and fix its position.

[0029] Step 2: When adjusting the angle of the crystal head, manually pull the moving frame 8 upward to remove the lower end of the connector 10 from the connector slot 11, thereby releasing the limiting effect of the connector 10 on the rotating shaft 3. At the same time, the connector block 9 will pull the spring 12 upward to continue to stretch it. Then, rotate the rectangular plate 4 up and down to make it rotate the crystal head up and down together, thereby adjusting the angle of the crystal head.

[0030] After adjusting the angle of the crystal head, remove the external force applied to the movable frame 8, so that the spring 12 pulls the plug block 9, the movable frame 8 and the plug tube 10 down together, so that the lower end of the plug tube 10 is inserted into the corresponding plug slot 11 to fix the rotating shaft 3 and the rectangular plate 4.

[0031] In summary, the steps for adjusting the crystal head in this application are relatively simple and time-saving, making it convenient for personnel to use when processing and testing crystal heads.

[0032] Second implementation method:

[0033] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0034] Figure 3 and Figure 5 A connecting plate 14 is placed against the side of the moving plate 7. A sponge plate 15 is fixedly connected to the end of the connecting plate 14 away from the moving plate 7. A connecting block 16 is fixedly connected to the upper end of the connecting plate 14. A limit tube 17 is threadedly connected inside the connecting block 16. In the initial state, the lower end of the limit tube 17 extends out from the connecting block 16 and is threadedly connected inside the moving plate 7.

[0035] The side end of the movable plate 7 is provided with a pair of reinforcing grooves 18, and the end of the connecting plate 14 away from the sponge plate 15 is fixedly connected with a pair of reinforcing strips 19 that are movably inserted into the reinforcing grooves 18.

[0036] During the process of constraining and fixing the position of the crystal head, the crystal head is clamped by the sponge plate 15. The sponge plate 15 not only increases the friction force on the outer end of the crystal head and improves its stability, but also makes the outer end of the crystal head less prone to wear, thereby preventing unnecessary damage and waste. When the sponge plate 15 is damaged and needs to be replaced, simply remove the limiting tube 17 from the connecting block 16 to separate it from the moving plate 7, then remove the reinforcing strip 19 from the reinforcing groove 18, and replace the sponge plate 15.

[0037] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
