As an important medium connecting machine tools and workpieces, tooling fixtures directly affect machining accuracy, production efficiency and manufacturing costs. As the manufacturing industry develops towards multi-variety, small-batch and customized directions, higher requirements are placed on the versatility and flexibility of tooling fixtures for horizontal CNC machine tools.

[0003] Horizontal CNC machine tools are known for their high precision and efficiency. Their horizontal spindle layout requires the use of special fixtures to achieve stable workpiece clamping. General-purpose fixtures connect to the machine tool table through standardized interfaces to ensure positioning accuracy at the micron level, meeting the stringent requirements of the aerospace and automotive manufacturing industries. General-purpose tooling fixtures are standardized and modular tools in the machining field. Their core function is to achieve rapid workpiece positioning and clamping, such as three-jaw self-centering chucks and four-jaw single-action chucks, which are suitable for clamping cylindrical or regular-shaped workpieces. However, current CNC machine tool tooling fixtures have poor stability during use, requiring operators to repeatedly stop the machine to calibrate the fixtures and re-clamp the workpieces, resulting in low clamping efficiency and inconvenience for daily use. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a general-purpose tooling fixture for horizontal CNC machine tools, comprising multiple movable plates, each movable plate having a tripod fixedly connected to its top.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see the appendix Figure 1 - Appendix Figure 3An embodiment of this utility model provides a general-purpose tooling fixture for horizontal CNC machine tools, including multiple movable plates 1. Each movable plate 1 has a tripod 4 fixedly connected to its top. A second rotating plate 14 is rotatably connected to the outer wall of the tripod 4. A first rotating plate 13 is rotatably connected to the top inner side of the second rotating plate 14. A pressing plate 11 is rotatably connected to the inner side of the first rotating plate 13. A straight rod 12 is fixedly connected to the middle inner side of the pressing plate 11. A pressing column 10 is fixedly connected to the bottom end of the straight rod 12. An adjustment mechanism 2 is provided on the outer wall of the movable plate 1. The adjustment mechanism 2 is used to adjust the clamping position of tooling of different specifications. A protective strip 8 is fixedly connected to the upper middle part of the outer wall of the multiple movable plates 1.

[0032] Specifically, the tripod 4 serves as the entire clamping device, with its outer wall rotatably connected to the rotating plate 14. This rotatable connection bearing structure ensures that the rotating plate 14 can move stably around the tripod 4. The inner top of the rotating plate 14 is rotatably connected to the rotating plate 13. The rotatable connection between the rotating plate 13 and the rotating plate 14 ensures the smoothness and accuracy of their rotation. When the straight rod 12 is subjected to a downward force, the pressing column 10 will move downward accordingly. The adjusting mechanism 2 works in coordination with the rotating components of the tripod 4, the rotating plate 14, the rotating plate 13, and the pressing plate 11. After the adjusting mechanism 2 adjusts the clamping range and clamping force, the rotation can be flexibly adjusted according to the actual position and shape of the tooling.

[0033] Please see the appendix Figure 3 - Appendix Figure 5 The adjustment mechanism 2 includes an elongated rod 202. The outer wall of the elongated rod 202 is disposed on the inner side of the movable plate 1. A connecting plate 203 is fixedly connected between adjacent elongated rods 202. The outer wall of each elongated rod 202 is provided with an external thread 201. The outer wall of the middle external thread 201 is threaded with a threaded knob 204. The outer wall of the outer external thread 201 is threaded with a threaded knob 205. A support plate 6 is fixedly connected to the bottom of the movable plate 1. An anti-slip pad 7 is fixedly connected to the bottom of the support plate 6.

[0034] Specifically, multiple elongated rods 202 are arranged on the inner side of the movable plate 1. When the movable plate 1 moves or is subjected to external force, the connecting plate 203 can evenly transmit and distribute the force on each elongated rod 202. The outer wall of each elongated rod 202 is provided with external threads 201. These external threads 201 are threaded knobs to realize the adjustment function. The support plate 6, elongated rods 202, connecting plate 203 and threaded knobs improve the installation and use flexibility of the equipment.

[0035] Please see the appendix Figure 1 - Appendix Figure 3The long rod 202 has a circular column 206 fixedly connected to the left and right ends of its outer wall. A protective column 207 is fixedly connected to the adjacent side of the multiple circular columns 206. A connecting plate 2 5 is fixedly connected to the top of the multiple adjacent movable plates 1. A connecting plate 1 3 is fixedly connected to the bottom of the adjacent movable plates 1. A handle 9 is fixedly connected to the top of the outer wall of the rotating plate 13. A protective sleeve is fixedly connected to the outer wall of the handle 9. Multiple anti-slip pads 7 are fixedly connected at the same horizontal height. The multiple movable plates 1 are all designed in an array.

[0036] Specifically, circular columns 206 are fixedly connected to both the left and right ends of the outer wall of the elongated rod 202. The circular columns 206 are firmly fixed to the ends of the elongated rod 202. Protective columns 207 are fixedly connected to adjacent sides of multiple circular columns 206. The protective columns 207 are important safety protection components in the device. Connecting plates 2 5 are fixedly connected to the top of adjacent moving plates 1. Connecting plates 2 5 play a role in strengthening the connection strength of the top of the moving plates 1. A handle 9 is fixedly connected to the top of the outer wall of the rotating plate 13. The handle 9 provides convenient operation for the operator. The operator can operate more easily and conveniently with the handle 9, which improves work efficiency and operation comfort.

[0037] Working principle: When a fixture is to be used on a CNC machine tool, the adjustment mechanism 2 is first adjusted according to the size of the fixture. Then, the fixture to be clamped is placed on the moving plate 1. The gripping rod 9 is then turned to one side, causing the rotating plate 2 14 and rotating plate 1 13 to rotate along the outer wall of the tripod 4, thereby pressing the pressing plate 11 downward. Finally, the pressing column 10 fixedly connected to the straight rod 12 contacts the surface of the fixture for fixation. Therefore, it can effectively ensure that the fixture does not shift or shake when it is being processed on the CNC machine tool, thus improving the stability of the fixture clamping.

[0038] Next, the connecting plate 203 is fixed to the elongated rod 202. This is done in conjunction with the rotation of the threaded knob 205 along the outer wall of the external thread 201, which pushes the moving plate 1 to move along one side of the outer wall of the elongated rod 202. After adjusting to the appropriate position for tooling clamping, the twisting threaded knob 204 is then rotated along the corresponding outer wall of the external thread 201 to limit the position of the moving plate 1 and prevent it from moving. Therefore, the position of the clamping legs can be effectively adjusted according to the size of the tooling to meet the clamping requirements of different specifications of tooling and improve the use effect of the equipment.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
