Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of external tool length measuring instruments, and in particular to a practical and simple external tool length measuring instrument. Background Technology
[0002] The working principle of an external tool length measuring instrument is mainly based on a contact measurement method. It typically includes a high-precision probe (or probe head), a measuring platform for mounting the tool, and a reader for displaying the measurement results. During measurement, the tool is mounted on the measuring platform, and the platform is moved to bring the probe into contact with the tool. When the probe contacts the tool, an internal switch or sensor is triggered, recording the current position information. By comparing the information from different positions, the tool length can be calculated. However, in existing measuring instruments, the sliding support is prone to dust accumulation due to the lack of shielding on both sides. This dust buildup affects the movement of the support and is difficult to clean, increasing the cleaning burden. Therefore, we have introduced a practical and simplified external tool length measuring instrument. Utility Model Content

[0023] Please see Figure 1-4 This utility model provides a technical solution:
[0024] A practical and simple external blade length measuring instrument includes a base 1, a grating ruler bracket 2 connected to the upper rear of the base 1, a first slider 3 movably connected to the front of the grating ruler bracket 2, and an HMI touch screen 4 fixedly connected to the left front of the base 1.
[0025] In this embodiment, a slot 15 is formed at the upper end of the base 1. A threaded rod 16 is movably connected to the upper part of the rear wall of the slot 15 via a bearing. A guide rod 11 is fixedly connected to the lower part of the rear wall of the slot 15. A slider 17 is threadedly connected to the outer surface of the threaded rod 16. The slider 17 is movably connected to the guide rod 11. A sliding groove 13 is formed on the upper part of both the left and right walls of the slot 15. A folding cover 14 is fixedly connected to the upper part of the front end of the slider 17. A first folding cover 12 is fixedly connected to the upper rear end of block 17. The other end of the first folding cover 12 is fixedly connected to the rear groove wall of the first slot 15. The other end of the second folding cover 14 is fixedly connected to the front groove wall of the first slot 15. The second folding cover 14 and the first folding cover 12 are both located in the two first sliding grooves 13. The second slider 17 is fixedly connected to the grating ruler bracket 2. The upper rear end of the first slider 3 has a threaded hole 31, the upper front end of the first slider 3 has a round hole 32, and the front end of the first slider 3 is equipped with a measuring component 33.
[0026] Through the above scheme: two first sliding grooves 13 are opened in the base 1. These two first sliding grooves 13 are in sliding cooperation with the second folding cover 14 and the first folding cover 12. The second folding cover 14 and the first folding cover 12 are placed in the two first sliding grooves 13. They can automatically fold and unfold according to the sliding state of the second slider 17. When the second slider 17 slides smoothly in the groove, the two folding covers can respond quickly, preventing external dust from entering the interior of the base 1 through the first slot 15, thereby ensuring the cleanliness and normal operation of the internal components of the base 1.
[0027] In this embodiment, the grating ruler bracket 2 has a second slot 23. The rear part of the inner wall of the second slot 23 is movably connected to the second threaded rod 22 via a bearing. The middle part of the inner wall of the second slot 23 is fixedly connected to the second guide rod 21. The front part of the left slot wall and the front part of the right slot wall of the second slot 23 both have second sliding grooves 24. The third folding cover 25 and the fourth folding cover 26 are slidably connected in the two second sliding grooves 24. The ends of the third folding cover 25 and the fourth folding cover 26 that are close to each other are fixedly connected to the first slider 3. The ends of the third folding cover 25 and the fourth folding cover 26 that are far apart from each other are fixedly connected to the upper and lower slot walls of the second slot 23.
[0028] Through the above solution: two second sliding grooves 24 are opened inside the grating ruler bracket 2. These two second sliding grooves 24 form a sliding connection with the third folding cover 25 and the fourth folding cover 26. When the first slider 3 moves up and down, it will drive the third folding cover 25 and the fourth folding cover 26 to make corresponding unfolding and folding actions, which prevents dust from entering the interior of the grating ruler bracket 2 from the second groove 23, greatly reducing the cleaning burden inside the grating ruler bracket 2.
[0029] It should be noted that this utility model describes a practical and simple external tool length measuring instrument. A tool holder bracket is mounted on a base 1 for holding the tool. A grating ruler bracket 2 is located on the base 1. By sliding the first slider 3 up and down, the measuring rod contacts the tool tip, enabling real-time monitoring of the tool length, which is displayed on the HMI touchscreen 4. Two first sliding grooves 13 are formed inside the base 1. These two first sliding grooves 13 are in sliding engagement with second folding covers 14 and first folding covers 12. The second folding covers 14 and first folding covers 12 are placed within these two first sliding grooves 13. They can automatically fold and unfold according to the sliding state of the second slider 17. When the second slider... When sliding smoothly in the groove, the two folding covers can respond quickly, preventing external dust from entering the base 1 through the first slot 15, thus ensuring the cleanliness and normal operation of the internal components of the base 1 and effectively extending its service life. The inside of the grating ruler bracket 2 has two second grooves 24, which form a sliding connection with the third folding cover 25 and the fourth folding cover 26. When the first slider 3 moves up and down, it will drive the third folding cover 25 and the fourth folding cover 26 to make corresponding unfolding and folding actions, blocking dust from entering the inside of the grating ruler bracket 2 through the second slot 23, greatly reducing the cleaning burden inside the grating ruler bracket 2.
