[0001] This invention belongs to the field of machine tool processing technology, and specifically relates to an assembly-type fixture for CNC machine tool processing. Background Technology

[0002] CNC machine tools are machine tools capable of machining workpieces with high precision and efficiency. Compared to traditional manual machine tools, CNC machine tools feature high precision, good repeatability, fast machining speed, and simple operation. Their main principle is to use a computer control system to precisely control the movement of the cutting tool, thereby completing the machining of workpieces with various complex shapes. Machine tool processing, as one of the core technologies of traditional manufacturing, has always received widespread attention. It not only has a significant impact on the technological level and production efficiency of manufacturing, but also plays a crucial role in promoting national economic development. The development of modern machine tool processing technology has not only improved the automation level of manufacturing, but also effectively improved production efficiency and product quality, laying the foundation for the upgrading and transformation of the manufacturing industry. Machine tool fixtures are commonly used tooling in the process of workpiece machining and assembly, used to clamp and fix workpieces for machining or assembly. Different types of machine tool fixtures are classified according to their specific uses, shapes, and structures. Different types of machine tool fixtures have their own applicable scope and characteristics. Selecting the appropriate machine tool fixture is very important for improving production efficiency and machining quality. When selecting machine tool fixtures, it is also necessary to consider the shape, material, clamping force, and required accuracy of the workpiece to ensure that the selected fixture can better meet the factory's production needs. For example, tubular and plate-shaped workpieces are frequently encountered during machine tool processing. Although these workpieces are similar in shape, their fixing methods during processing will still have some differences due to slight differences in their clamping parts. Therefore, different fixtures need to be changed according to the workpiece being processed, which affects the processing efficiency.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] To provide a highly practical and simple-to-operate machine tool fixture that addresses the challenges of machining tubular and plate-shaped workpieces, which are frequently encountered in machine tool processing. While these workpieces may have similar shapes, subtle differences in their clamping mechanisms can lead to variations in their fixing methods, necessitating the use of different fixtures depending on the workpiece shape, thus impacting processing efficiency. (See also...) Figures 1-5 This invention discloses an assembled fixture for CNC machine tool processing, including a mounting base plate 1, a mounting plate 2, and a movable plate 3. The mounting plate 2 is detachably connected to one side of the mounting base plate 1, and the movable plate 3 is slidably mounted on the other side of the mounting base plate 1. The mounting plate 2 is provided with a first telescopic component 4, the output end of which is connected to the movable plate 3. Both the mounting plate 2 and the movable plate 3 have clamping components detachably connected to their opposite ends. The two clamping components are arranged facing each other. The clamping components include a second telescopic arm 5, a central circular plate 6, and a third telescopic arm 7. The second telescopic arm 5 is vertically mounted on both the mounting plate 2 and the movable plate 3. The output end of the second telescopic arm 5 is provided with an adjustment plate 8. The central circular plate 6 is rotatably mounted on the adjustment plate 8, and the adjustment plate 8 is provided with a servo motor 9 that is drively connected to the central circular plate 6. The third telescopic arm 7 is fixedly connected to both the left and right sides of the central circular plate 6, and a chuck 10 is fixedly connected to the end of the third telescopic arm 7.

[0030] This modular fixture can clamp and fix workpieces of different shapes and sizes, greatly improving its applicability and processing efficiency, and effectively solving the problem of different workpiece fixing methods during processing. Its specific working principle is as follows: First, before use, the operator needs to check whether each component of the fixture is intact and in normal working condition. Then, when a workpiece needs to be clamped, the first telescopic component 4 is activated, pushing the movable plate 3 away from the mounting plate 2, so that the two sets of clamping components on the mounting plate 2 and the movable plate 3 are separated to accommodate the length of the workpiece. At the same time, the second telescopic arm 5 and the third telescopic arm 7 are also activated and extended to accommodate the height and width of the workpiece, ensuring that the workpiece can be placed. Then, the workpiece is placed between the clamping components. Afterwards, the first telescopic component 4 begins to retract, bringing the movable plate 3 closer to the mounting plate 2, so that the two sets of clamping components above initially clamp the two ends of the workpiece. Immediately afterwards, the third telescopic arm 7 also begins to retract, so that the chuck 10 at the end of the third telescopic arm 7 is pressed tightly against the edge of the workpiece, completing the clamping and fixing of the workpiece. After clamping and fixing, the second telescopic arm 5 continues to retract, adjusting the workpiece to a suitable processing height for subsequent operations by CNC machine tools and other processing equipment. Finally, the CNC machine tool or other processing equipment can be started to perform cutting, grinding, or other processing operations on the workpiece according to the processing program and requirements. During this process, the working angle of the clamping assembly can be flexibly adjusted according to the shape of the workpiece and specific processing requirements by adjusting the servo motor 9 on the adjustment plate 8. This adjustment ensures that the workpiece achieves the expected processing accuracy, thereby significantly improving product quality. In addition, this assembled fixture adopts a modular design, and each component can be easily disassembled and replaced. This not only reduces maintenance costs but also improves maintenance efficiency, enabling the fixture to maintain stable performance and good working condition during long-term use. This modular design also brings expandability, allowing for the selection of different sized expandable accessories according to different shapes and sizes of workpieces, further improving the flexibility and adaptability of the fixture.

[0031] In one specific implementation, see Figure 2 The upper surface of the mounting base plate 1 is provided with a groove 11. The first telescopic component 4 includes a pneumatic telescopic rod 401 and a rectangular column 402, which are respectively installed on both sides of the groove 11. The mounting plate 2 and the mounting base plate 1 are provided with matching fixing holes. Fixing bolts 12 are inserted into the inner side of the fixing holes. The mounting plate 2 is fixedly connected above the pneumatic telescopic rod 401. The movable plate 3 is fixedly connected above the rectangular column 402. The rectangular column 402 is fixedly connected to the output end of the pneumatic telescopic rod 401.

[0032] By creating a groove 11 on the upper surface of the mounting base plate 1 and installing the pneumatic telescopic rod 401 and rectangular column 402 within the groove 11, space is effectively saved, resulting in a more compact and rationally laid-out overall fixture structure. By mounting the mounting plate 2 and movable plate 3 above the pneumatic telescopic rod 401 and rectangular column 402 respectively, a stable support foundation is provided for the mounting plate 2 and movable plate 3. The movement of the pneumatic telescopic rod 401 allows for flexible adjustment of the distance between the movable plate 3 and the mounting plate 2, thereby achieving effective clamping of the workpiece along its length. This design effectively prevents fixture loosening or displacement caused by vibration or external forces during processing, ensuring the accuracy and safety of the processing. Furthermore, the pneumatic telescopic rod 401 has a fast response and high control precision, enabling rapid and accurate adjustment of the movable plate 3's position. This significantly shortens the workpiece clamping time, ensuring the processing accuracy and stability of the workpiece, thereby improving processing efficiency and product quality. It is worth mentioning that when the workpiece is heavy, the number of grooves 11 can be increased according to actual needs, and they can be arranged in parallel. The number of pneumatic telescopic rods 401 and rectangular columns 402 can also be increased to match the grooves 11, thereby improving the load-bearing capacity of the mounting plate 2 and the movable plate 3.

[0033] In one specific implementation, see Figure 4 The second telescopic arm 5 includes a hollow plate 501 and a second hydraulic telescopic rod 502. Both sides of the hollow plate 501 are fixedly connected to a connecting plate 13. The connecting plate 13 and the mounting base plate 1 are provided with matching connecting holes. A connecting bolt 14 is inserted into the inner side of the connecting hole. The second hydraulic telescopic rod 502 is installed inside the hollow plate 501. The adjusting plate 8 is connected to the output end of the second hydraulic telescopic rod 502.

[0034] The hollow plate 501 is connected to the mounting base plate 1 by precisely corresponding connecting holes on the connecting plates 13 on both sides, and secured by connecting bolts 14, achieving a stable yet easy-to-assemble and disassemble connection between the hollow plate 501 and the mounting base plate 1. This design not only simplifies the installation process but also improves maintenance convenience, providing ease of assembly and disassembly for the clamping components and the mounting base plate 1. The second hydraulic telescopic rod 502 is installed inside the hollow plate 501, and its output end is directly connected to the adjusting plate 8, allowing the position of the adjusting plate 8 to be precisely and smoothly adjusted according to processing requirements, which is beneficial for precise control of processing height. In addition, the design of the hollow plate 501 not only reduces the weight of the overall structure but also provides space for the internal installation of the second hydraulic telescopic rod 502, making the entire structure of the second telescopic arm 5 more compact, which helps save installation space and improves the flexibility of equipment layout.

[0035] In one specific implementation, see Figure 4A second protective shell 15 is provided below the adjustment plate 8. The second protective shell 15 is located outside the second hydraulic telescopic rod 502 and is connected to the output end of the second hydraulic telescopic rod 502. The second protective shell 15 is movably disposed inside the hollow plate 501.

[0036] By providing a second protective shell 15 on the outside of the second hydraulic telescopic rod 502, effective protection and isolation of the second hydraulic telescopic rod 502 are achieved, ensuring the stability and safety of the second hydraulic telescopic rod 502 during operation. The second protective shell 15 is movably disposed within the hollow plate 501, abutting against the inner wall of the hollow plate 501. When the clamping assembly shifts under the weight of the workpiece being processed or under external force, the resulting stress is first transmitted to the hollow plate 501 through the second protective shell 15, thereby greatly reducing the load borne by the second hydraulic telescopic rod 502, extending the service life of the second hydraulic telescopic rod 502, and thus reducing maintenance and replacement costs.

[0037] In one specific implementation, see Figure 2 A rotating shaft 16 is fixedly connected to the center of the central circular plate 6. A bearing 17 is fixedly sleeved on the rotating shaft 16. The bearing 17 is installed on the adjustment plate 8. The rotating shaft 16 passes through the adjustment plate 8 and is fixedly connected to the output shaft of the servo motor 9.

[0038] The tight connection between the output shaft of the servo motor 9 and the rotating shaft 16 ensures precise angle adjustment of the clamping assembly, which is crucial for machining tasks requiring high precision control. The design of the bearing 17 provides smooth and stable rotational support for the rotating shaft 16, reducing friction and resistance during rotation. This ensures that the central circular plate 6 rotates smoothly under the drive of the servo motor 9, providing a strong guarantee for the long-term stable operation and efficient machining of the equipment.

[0039] In one specific implementation, see Figure 3 The third telescopic arm 7 includes an air housing 701, a third hydraulic telescopic rod 702, and a third protective housing 703. The air housing 701 is fixedly connected to the central circular plate 6. The third hydraulic telescopic rod 702 is installed inside the air housing 701. The third protective housing 703 is located outside the third hydraulic telescopic rod 702 and is connected to the output end of the third hydraulic telescopic rod 702. The third protective housing 703 is movably disposed inside the air housing 701. The clamp 10 is fixedly connected to the end of the third protective housing 703.

[0040] The third hydraulic telescopic rod 702 is installed inside the hollow shell, and its output end is directly connected to the third protective shell 703. This allows the position of the third protective shell 703 to be precisely and smoothly adjusted according to processing requirements, which is beneficial for precise control of the processing width. The hollow shell design not only reduces the weight of the overall structure but also provides space for the internal installation of the third hydraulic telescopic rod 702, making the entire structure of the third telescopic arm 7 more compact, saving installation space and improving the flexibility of equipment layout. In addition, the third protective shell 703 is arranged on the outside of the third hydraulic telescopic rod 702 and is movably set inside the air shell 701. The third protective shell 703 abuts against the inner wall of the hollow shell. During the process of clamping the workpiece in the chuck 10, when the workpiece shifts due to its own weight or external force, the stress generated is first transmitted to the hollow shell through the third protective shell 703. This greatly reduces the load on the third hydraulic telescopic rod 702, extends its service life, and reduces maintenance and replacement costs.

[0041] In one specific implementation, see Figures 1-3 The upper and lower sides of the central clamp are fixedly connected with third telescopic arms 7, and the ends of the third telescopic arms 7 are fixedly connected with clamps 10.

[0042] Third telescopic arms 7 are added to the upper and lower sides of the central clamping plate. These, in conjunction with the original third telescopic arms 7 located on the left and right sides, enable multi-point clamping of the workpiece. This design allows the workpiece to be clamped securely from all directions, greatly enhancing stability and reliability during clamping. For workpieces with regular shapes, this clamping design demonstrates unique advantages. By precisely adjusting the extension length of each third telescopic arm 7, it can be ensured that the central axis of the workpiece and the center of the central circular plate 6 are on the same straight line. During processing, this reduces the workload of continuously adjusting the clamping position and effectively prevents deviations caused by improper workpiece clamping or angular rotation, which could lead to the machining surface not accurately aligning with the predetermined position, thus preventing machining deviations or error accumulation and effectively improving machining accuracy and finished product quality.

[0043] In one specific implementation, see Figures 1-3 The chuck 10 has anti-slip grooves 18 evenly arranged on the side facing the central circular plate 6, and a rubber pad 19 is fixedly connected to the outside of the chuck 10.

[0044] The anti-slip groove 18 design allows the chuck 10 to generate greater friction when clamping the workpiece in the width direction, effectively preventing the workpiece from sliding or falling off due to vibration or external forces during processing, thereby improving the stability and safety of clamping. The rubber pad 19 design cushions the direct impact and collision of the workpiece on the chuck 10 during the clamping and fixing process, effectively reducing the potential risk of damage to the chuck 10 due to frequent clamping operations and improving the durability of the chuck 10.

[0045] In one specific implementation, see Figure 1 , Figure 4 and Figure 5 It also includes a safety fixing component 20, which includes a fixing clip 2001 and a clamping bolt 2002. The two ends of the fixing clip 2001 abut against the bottom surface of the mounting base plate 1 and the top surface of the movable plate 3, respectively. The top surface of the fixing clip 2001 has a through hole, and the clamping bolt 2002 is threaded into the through hole and abuts against the top surface of the movable plate 3.

[0046] The presence of the safety fixing component 20 adds an important safety guarantee for clamping the workpiece. Even in adverse conditions such as potential failure or loosening of the pneumatic telescopic rod 401, the safety fixing component 20 continues to function, preventing displacement of the movable plate 3. This ensures that the clamping components on the mounting plate 2 and the movable plate 3 maintain effective clamping of the workpiece, guaranteeing the smooth completion of the predetermined processing task and providing a solid guarantee for smooth production. Specifically, once the distance between the mounting plate 2 and the movable plate 3 is determined, the fixing clamp 2001 is used to insert the mounting base plate 1 and the movable plate 3 from the side. By tightening the clamping bolt 2002, the clamping bolt 2002 and the top surface of the movable plate 3 are pressed together, effectively clamping the mounting base plate 1 and the movable plate 3 and preventing loosening.

[0047] In one specific implementation, see Figure 1 and Figure 2 The mounting base plate 1 has insertion holes 21 on both sides, and the worktable has insertion blocks 22 that match the insertion holes 21.

[0048] By fixing the insert 22 to the workbench, when connecting the mounting base plate 1 to the workbench, it is only necessary to align the insertion holes 21 on both sides of the mounting base plate 1 with the insert 22 and insert it, without the need for complicated bolt connections or welding processes, which saves both time and effort. Moreover, when it is necessary to maintain or replace the mounting base plate 1, it can be quickly disassembled by simply pulling the mounting base plate 1 out of the insert 22, without the need for additional tools or complicated operating procedures, which greatly facilitates the daily maintenance and upgrade of the equipment.

[0049] In summary, it can be seen that this modular fixture has a simple and compact structure, is easy to operate, and is very convenient to use. Workers can fix the workpiece with simple operations without complicated adjustments and replacement processes, saving a lot of time and labor costs, and has broad application prospects.
