Description

Technical Field

[0001] The utility model relates to the technical field of CNC machining assistance, in particular to a CNC machining assistance device for hardware. Background Art

[0002] CNC is the abbreviation of Computer Numerical Control, which is an automated machine tool that enables the machine tool to perform prescribed actions and process the blank into semi-finished or finished parts through tool cutting. When using CNC to process hardware, auxiliary tools are required, such as fixtures to fix the hardware;

[0003] The existing CNC machining auxiliary devices for hardware have a relatively simple structure. Most of them can only clamp and fix the two sides of the hardware, and it is not convenient to reinforce the surroundings and the top. When the processed hardware is a thin plate structure, the moment the tool contacts the hardware will cause vibration, and even press the hardware to deform and make it out of the clamping state. The practicality is insufficient. Therefore, we propose a CNC machining auxiliary device for hardware. Utility Model Content

[0031] Example 2

[0032] like Figure 1-3As shown, the limit block 102 is slidably connected to the limit groove 101, and the limit block 102 is fixedly connected to the movable seat 203. Through the fixed connection between the limit block 102 and the movable seat 203, the movable seat 203 can be limited during the sliding process to prevent it from deflecting and improve the stability of use. The screw rod 104 is rotatably connected to the base 1, and the slider 105 is adapted to the screw rod 104. The slider 105 is slidably connected to the slide groove 103. The slider 105 is fixedly connected to the movable seat 203.
