Description

Technical Field

[0001] This utility model relates to the field of button measurement fixture technology, specifically a three-sided prism projection fixture for button measurement. Background Technology

[0002] In the field of electronic device manufacturing, buttons, as crucial components for human-computer interaction, directly impact the user experience and reliability of products due to their dimensional accuracy and surface quality. Therefore, button measurement is an indispensable part of the production process. Traditional button measurement methods typically rely on manual operation, requiring measurement personnel to use tools such as calipers and microscopes to measure each surface of the button individually. This method suffers from the following problems: Low efficiency: Since buttons usually require measurement of multiple surfaces, traditional methods require measurement personnel to manually flip the buttons and measure each surface individually. This operation is not only time-consuming but also increases workload, making it difficult to meet the high-efficiency requirements of modern production lines. Insufficient accuracy: Manually flipping buttons can easily lead to positional shifts, especially when measuring small or complex-shaped buttons, which directly affect the accuracy of the measurement results. Furthermore, manual operation has poor repeatability; measurement results from different personnel or at different times may vary significantly. Complex operation: Traditional fixtures have simple structural designs and limited functions, making simultaneous multi-faceted measurement impossible. Measurement personnel need to repeatedly adjust the button positions and measuring tools, making the process cumbersome and prone to errors. Limited applicability: As electronic devices become smaller and more precise, buttons are becoming smaller and more complex in shape, making it difficult for traditional measurement methods to meet the requirements of high-precision measurement.

[0003] To address these issues, some improved fixture designs have emerged in recent years. For example, some fixtures combine fixed clamps with optical measurement to improve measurement efficiency. However, these fixtures still suffer from the following drawbacks: complex structure, high manufacturing cost, and difficult maintenance. Optical measurement systems typically require complex calibration processes, making operation difficult. Furthermore, the fixtures lack versatility and struggle to adapt to buttons of different sizes and shapes.

[0004] Therefore, there is an urgent need for a fixture that is simple in structure, easy to operate, and capable of multi-face synchronous measurement, in order to improve the efficiency and accuracy of button measurement and meet the needs of modern production. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a three-sided prism projection fixture for button measurement, enabling simultaneous measurement of the three angles of the button and improving measurement efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A three-sided prism projection fixture for button measurement includes a base and multiple clamping assemblies mounted on the base. The base has mounting slots adapted to the clamping assemblies, and the clamping assemblies are detachably inserted into the mounting slots. Each clamping assembly includes a base, a pressure block, a pull rod, a slider, a guide post, and a spring. The base is detachably inserted into the mounting slot. The end of the guide post is fixed to the base. The slider is slidably mounted on the guide post. The spring is sleeved on the guide post, with one end abutting against the base and the other end abutting against the slider. The pull rod is slidably mounted on the base, with one end fixedly connected to the slider, and the pressure block fixed to the other end of the pull rod. The spring pushes the slider to slide on the guide post, and the slider drives the pull rod to move synchronously, pressing the pressure block against the base. The pressure block is located outside the mounting slot. Three prisms are fixedly mounted on the base, distributed outside the mounting slot and facing the pressure block.

[0008] Preferably, the base has an internal cavity, and the slider, guide post and spring are placed in the cavity.

[0009] Preferably, the plurality of mounting slots are distributed in an array at equal intervals along the length of the base.

[0010] Preferably, a stop block adapted to the pressure block is fixedly provided on the base, and the pressure block abuts against the stop block.

[0011] Preferably, a guide plate is fixedly provided on the outside of the base; a guide groove is provided on the base, the guide groove is connected to the mounting groove, and the guide plate is slidably placed in the guide groove.

[0012] Preferably, the base is provided with a transverse through hole, which communicates with the chamber.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Multi-faceted measurement: By using the refraction imaging principle of three prisms, the button can be measured simultaneously from three angles without the need for manual flipping, which significantly improves measurement efficiency.

[0015] High stability: The clamping assembly, through the cooperation of springs and pressure blocks, ensures that the button is firmly fixed during measurement, avoiding displacement caused by flipping or moving.

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2As shown, a three-sided prism projection fixture for button measurement includes a base 1 and multiple clamping assemblies 2 disposed on the base 1. The base 1 has mounting grooves 6 adapted to the clamping assemblies 2, extending downwards from the upper end of the base 1. The clamping assemblies 2 are detachably inserted into the mounting grooves 6. Each clamping assembly 2 includes a base 21, a pressure block 25, a pull rod 26, a slider 27, a guide post 23, and a spring 22. The base 21 is detachably inserted into the mounting groove 6. The end of the guide post 23 is fixed to the base 21. The slider 27 is slidably mounted on the guide post 23. On post 23; spring 22 is sleeved on post 23, one end abutting against base 21, the other end abutting against slider 27; pull rod 26 is slidably mounted on base 21, one end is fixedly connected to slider 27, and pressure block 25 is fixed to the other end of pull rod 26; spring 22 pushes slider 27 to slide on post 23, slider 27 drives pull rod 26 to move synchronously, so that pressure block 25 is pressed against base 21; pressure block 25 is located outside mounting groove 6; three prisms 4 are fixedly mounted on base 1, the three prisms 4 are distributed on the outside of mounting groove 6 and facing pressure block 25. Pushing pressure block 25 compresses spring 22, so that pressure block 25 moves away from base 21. When the button is placed between pressure block 25 and base 21, after releasing slider 27, spring 22 pushes slider 27 to slide, and pressure block 25 presses and fixes the button. The clamping assembly 2 is installed into the mounting slot 6. Using the refraction imaging principle of the three prisms 4, the button is measured from three different angles, allowing for a single measurement without manual flipping.

[0027] In this embodiment, a stop block adapted to the pressure block 25 is fixedly provided on the base 21. The pressure block 25 abuts against the stop block, clamping and fixing the button between the pressure block 25 and the stop block.

[0028] In this embodiment, a guide plate 24 is fixedly provided on the outside of the base 21; a guide groove 5 is provided on the base 1, the guide groove 5 is connected to the mounting groove 6, and the guide plate 24 is slidably placed in the guide groove 5 so that the base 21 is accurately installed into the mounting groove 6.

[0029] In this embodiment, a transverse through hole 3 is provided on the base 1. The transverse through hole 3 communicates with the chamber. The transverse through hole 3 facilitates the removal of the clamping assembly 2 from the mounting groove 6.

[0030] How to use

[0031] Install clamping assembly 2: Insert clamping assembly 2 into the mounting groove 6 on the base 1, ensuring that the guide plate 24 slides into the guide groove 5, so that the base 21 is accurately positioned.
