[0008] The top end of the first moving frame is installed with a Z-axis motor, and a lead screw is also installed at the output end of the Z-axis motor inside the first moving frame. Sliders are also provided on the back of the second moving frame, and the second moving frame is installed on the first moving frame through the cooperation of the sliders and the lead screw of the first moving frame.

[0009] On the basis of the above technical solution, the present utility model can also be improved as follows.

[0010] Further, guide blocks are provided on both sides of the walking frame, and the walking frame cooperates with the guide rods of the machine frame through the guide blocks to maintain the moving direction of the walking frame.

[0011] The beneficial effect of adopting the above further solution is:

[0012] The cooperation between the guide block and the guide rod provides accurate guidance for the walking frame, ensuring the stability and accuracy of the walking frame during movement. The close cooperation between the guide block and the guide rod can also effectively reduce the vibration of the walking frame during movement, further ensuring the stability and precision of processing.

[0013] Further, guide rods are provided on both sides of the walking frame where the lead screw is located, and a guide block is provided on the back of the first moving frame. The first moving frame cooperates with the guide rods of the walking frame through the guide block to guide the moving direction of the first moving frame.

[0014] The beneficial effect of adopting the above further solution is:

[0015] The cooperation between the guide rod and the guide block provides an accurate guiding path for the first moving frame, ensuring its linearity and stability during movement. The close cooperation between the guide rod and the guide block can also effectively reduce the vibration of the first moving frame during movement, making its operation more stable, and further ensuring the stability and precision of processing.

[0016] Further, a guide rod is provided on one side of the second moving frame where the lead screw is located, and a guide block is provided on the back of the second moving frame. The second moving frame cooperates with the guide rods of the first moving frame through the guide block to guide the moving direction of the second moving frame.

[0020] The beneficial effect of adopting the above further solution is:

[0021] Through the design of the handle, bracket and hook, the workpiece can be quickly and conveniently clamped onto the fixture, enabling the fixture to adapt to different types of workpieces. This flexibility enhances the applicable range of the machine tool. This design greatly simplifies the clamping process and improves work efficiency. The fixture is fixed to the machine frame by magnetic adsorption between the bottom plate and the magnetic adsorption plate. This non-mechanical connection method of fixation is both stable and reliable. Even during high-speed machining, the workpiece can be kept stable without movement, avoiding machining errors.

[0022] Furthermore, the rubber cushion plate is located between the magnetic adsorption plate and the fixture.

[0023] The beneficial effects of adopting the above further scheme are as follows:

[0024] The rubber cushion plate has good elasticity and resilience, and can effectively absorb and disperse the vibrations from the machine tool or the machining process. This buffering effect helps to protect the magnetic adsorption plate and the fixture from vibration impact, thereby extending their service life. Reducing vibrations can also improve the stability during the machining process, and further enhance the machining accuracy and surface quality.

[0025] Furthermore, the magnetic adsorption plate is provided with a fixing frame, an electromagnet is embedded in the fixing frame, a cage is arranged outside the electromagnet, and the two fixing frames press on the cage of the electromagnet to clamp and fix the electromagnet.

[0026] The beneficial effects of adopting the above further scheme are as follows:

[0027] By pressing the cages of the electromagnet with the two fixing frames, the clamping and fixing of the electromagnet is realized. This double-fixing method greatly enhances the stability of the electromagnet on the magnetic adsorption plate, preventing the electromagnet from loosening or falling off during the working process. The electromagnet is firmly fixed in the fixing frame and can give full play to its adsorption force to ensure the stable adsorption of the workpiece.

[0028] The utility model provides a special numerical control machine tool for precision tools. It has the following beneficial effects:

[0029] The design of the fixture is to ensure that the workpiece always remains stable during the machining process. Through the combination of the base, handle, bracket and hook, this fixing device can tightly clamp the workpiece, not only preventing the workpiece from moving during machining, but also adapting to workpieces of different shapes and sizes. In this way, machining errors caused by workpiece movement or loosening are avoided, ensuring the machining accuracy.

[0030] The fixing fixture not only has a stable structure, but also is fixed on the machine frame by the mutual adsorption of the bottom plate and the magnetic adsorption plate. This means that the position of the fixing fixture can be adjusted according to the size and shape of the workpiece, and the fixture can be flexibly moved as needed during use. This adjustability enhances the applicable range of the machine tool, enabling it to process workpieces of various different specifications, thereby improving the versatility of the machine tool and the convenience of operation.

[0031] The magnetic adsorption plate is inlaid with an electromagnet and firmly holds the electromagnet through a fixing frame and a cage. This design ensures a stable and strong adsorption force between the fixing fixture and the machine frame, avoiding the risk of workpiece displacement due to insufficient adsorption during the processing. The use of the electromagnet enables the adsorption force to be controlled as needed, further enhancing the stability and safety of the processing.

[0032] A rubber cushion plate is laid between the magnetic adsorption plate and the fixing fixture. This design is to effectively reduce the vibration of the machine tool during the processing. The rubber cushion plate can absorb part of the mechanical vibration and impact force, reducing the vibration transmitted to the workpiece, thereby helping to improve the processing accuracy. Especially when processing high-precision parts, this shock-absorbing design can significantly reduce the influence of micro-vibrations on the processing accuracy and improve the surface quality of the workpiece.
