Background Technique

[0002] A measuring grating for a precision numerical control machine tool is a device used for high-precision position measurement and is widely applied to numerical control machine tools, automation equipment and precision instruments. Its main function is to monitor the displacement and position of the machine tool in real time to ensure high precision and high stability in the machining process. The measuring grating for a precision numerical control machine tool is one of the key technologies indispensable in modern manufacturing industry, which can effectively improve production efficiency and product quality. When in use, the grating scale needs to be fixed on the base of the machine tool to ensure that it will not displace during the working process. However, usually, it is not convenient to quickly install the measuring grating during the installation process, making it difficult for the installation structure to reach the established expected usage efficiency. Therefore, we propose an installation structure of a measuring grating for a precision numerical control machine tool to facilitate solving the above-mentioned problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-4 , the present utility model provides a technical solution, a precision CNC machine tool measuring grating installation structure, including a machine tool main body 1 and a tool rest 19. The machine tool main body 1 is connected to a left connecting block 5 through a clamping connection mechanism. The clamping connection mechanism includes the machine tool main body 1, a first push rod 2, a stop block 3, a clamping block 4, and a connecting block 5. The inside of the machine tool main body 1 is fixedly connected to the first push rod 2, and the front end of the first push rod 2 is connected to the stop block 3, and the stop block 3 is clamped with the clamping block 4. The clamping block 4 is fixedly connected to the connecting block 5, and the connecting block 5 is connected to a moving rod 7 through a pin 6. The moving rods 7 are symmetrically arranged about the center of a fixed block 8, and both moving rods 7 are connected to a connecting block 5 through a pin 6, and the connecting blocks 5 are respectively connected to the machine tool main body 1 and a moving block 11, and the front ends of the moving rods 7 are slidably connected to the inside of the fixed block 8. The first grating scale 10 is connected above the fixed block 8, and the moving rods 7 are connected to a first cursor 9;

[0018] During use, after inserting the clamping block 4 at the front end of the connecting block 5 into the card slot inside the machine tool main body 1, at this time, start the first push rod 2 inside the machine tool main body 1 to drive the stop block 3 to move, so that after the stop block 3 is clamped with the clamping block 4, install the connecting block 5. At this time, connect the moving rod 7 and the connecting block 5 through the pin 6, and at the same time connect the other moving rod 7 to the connecting block 5 on the surface of the moving block 11 through the pin 6. When the tool rest 19 moves left and right, the moving block 11 drives the connecting block 5 to move, so that the connecting block 5 drives the moving rod 7 to slide inside the fixed block 8. Cooperating with the first cursor 9 above the moving rod 7 and the first grating scale 10 on the surface of the fixed block 8 can control the moving distance, and better measure the moving distance of the tool;

[0019] The tool rest 19 is connected to the moving plate 12 through a fixing mechanism. The fixing mechanism includes the moving plate 12, the second push rod 15, the adjusting plate 16, the clamping block 17, and the sliding rod 18. The inside of the moving plate 12 is fixedly connected to the second push rod 15, and the front end of the second push rod 15 is fixedly connected to the adjusting plate 16. The adjusting plate 16 is slidably connected to the clamping block 17, the clamping block 17 is slidably connected to the sliding rod 18, and the sliding rod 18 is fixedly connected to the moving plate 12. The clamping blocks 17 are symmetrically arranged about the center of the adjusting plate 16, and the inner sides of the clamping blocks 17 are slidably connected to both sides of the adjusting plate 16. Both clamping blocks 17 are slidably connected to the sliding rod 18. The moving plate 12 is connected to the moving block 11, and the second grating scale 13 is connected above the moving block 11. The moving plate 12 is connected to the second cursor 14;

[0020] At this time, start the second push rod 15 inside the moving plate 12 to drive the adjusting plate 16 to move, so that the moving plate 12 drives the clamping block 17 to slide. At this time, after the clamping block 17 slides above the sliding rod 18, the clamping block 17 is inserted into the card slot on the surface of the tool rest 19 and engaged, completing the connection between the moving plate 12 and the tool rest 19. When the tool on the tool rest 19 moves up and down during the use of the machine tool, the tool rest 19 drives the moving plate 12 to slide above the moving block 11. At this time, after the second cursor 14 above the moving plate 12 slides above the second grating scale 13, the specific distance of the movement of the tool rest 19 can be understood.

[0021] Working principle: When measuring the grating installation structure using a precision CNC machine tool, during use, the chuck 4 at the front end of the connecting block 5 is inserted into the card slot inside the machine tool main body 1. Then, the first push rod 2 inside the machine tool main body 1 is started to drive the stop block 3 to move. After the stop block 3 and the chuck 4 are engaged, the connecting block 5 is installed. At this time, the moving rod 7 and the connecting block 5 are connected through the pin 6, and at the same time, the moving rod 7 on the other side is connected to the connecting block 5 on the surface of the moving block 11 through the pin 6. Then, the second push rod 15 inside the moving plate 12 is started to drive the adjusting plate 16 to move, so that the moving plate 12 drives the clamping block 17 to slide. At this time, after the clamping block 17 slides above the slide bar 18, the clamping block 17 is inserted into the card slot on the surface of the tool holder 19 and engaged, completing the connection between the moving plate 12 and the tool holder 19. When the tool above the tool holder 19 moves up and down during the use of the machine tool, the tool holder 19 drives the moving plate 12 to slide above the moving block 11. At this time, the second cursor 14 above the moving plate 12 slides above the second grating scale 13, and the specific moving distance of the tool holder 19 can be understood. When the tool holder 19 moves left and right, the moving block 11 drives the connecting block 5 to move, so that the connecting block 5 drives the moving rod 7 to slide inside the fixed block 8. The moving distance can be controlled by matching the first cursor 9 above the moving rod 7 and the first grating scale 10 on the surface of the fixed block 8, and the moving distance of the tool can be measured better, thus completing a series of operations. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Therefore, in any regard, the embodiments should be regarded as exemplary and non-restrictive.
