Description

Technical Field

[0001] This utility model relates to the field of lock manufacturing and processing technology, and in particular to a precision CNC machine tool for lock cutting. Background Technology

[0002] Locks are devices that serve a sealing function, including the lock body, key, and related accessories. They can be opened by key, light, electricity, magnetism, sound, or fingerprint, and have both protective, management, and decorative functions. Padlocks are the oldest and most widely used type of lock. Their characteristic is that the lock beam is connected to the lock body to form a closed structure, which is suitable for various scenarios. Currently, when manufacturing lock beams, a straight rod is usually bent into a U-shape, which is then installed on a workbench. The two straight segments of the U-shape are cut by a cutting device. Traditional lock beam manufacturing processes suffer from low efficiency and insufficient precision. The introduction of CNC machine tools has provided a direction for technological upgrading. At the same time, when cutting the two straight segments of the U-shape using a CNC machine tool, it is also necessary to fix it.

[0003] Traditional machining relies on manual clamping or general-purpose fixtures (such as flat-jaw pliers), which are difficult to adapt to the arc structure of U-shaped bars. Uneven clamping force can easily cause workpiece displacement. Workpiece displacement or deformation can cause the cutting position to deviate from the preset coordinates, resulting in a serious decrease in cutting accuracy. Therefore, we propose a precision CNC machine tool for lock cutting. Utility Model Content

[0027] Example 2

[0028] like Figure 1-4As shown, this utility model provides a technical solution: a precision CNC machine tool for lock cutting. The moving component 2 includes a moving groove 201, a threaded rod 202 is provided inside the moving groove 201, and a moving block 203 is provided inside the moving groove 201 and threadedly connected to the threaded rod 202. A moving seat 204 is connected to the top end of the moving block 203. A second drive motor 205 is provided on the front of the operating table 1. The output end of the second drive motor 205 is connected to one end of the threaded rod 202. The moving component 2 drives the threaded rod 202 to rotate through the second drive motor 205, realizing the linear movement of the moving block 203 threadedly connected to the threaded rod 202, so that the cutting saw blade 401 can move accurately and smoothly along a predetermined path, ensuring... Cutting precision and efficiency: The top of the moving component 2 is equipped with a connecting seat 3, and a hydraulic cylinder 301 is installed on one side of the connecting seat 3. The output end of the hydraulic cylinder 301 extends out of the other side wall of the connecting seat 3 and is connected to a first drive motor 4. The output end of the first drive motor 4 is connected to a cutting saw blade 401. The first drive motor 4 drives the cutting saw blade 401 to rotate at high speed, which is the power source for the cutting operation. The hydraulic cylinder 301 adjusts the position of the cutting saw blade 401 through extension and retraction to adapt to the cutting requirements of lock bodies 7 of different sizes, ensuring the accuracy and consistency of the cutting depth. The other side of the front of the operating table 1 is equipped with a control panel 9. The operator controls the operation status of the entire device through the control panel 9, which improves the ease of operation of the CNC machine tool.

[0029] The working process of this utility model is as follows: When using a precision CNC machine tool for lock cutting, firstly, the lock body 7 (U-shaped rod) is placed into the fixing groove 501 (the fixing groove 501 is designed as a U-shaped groove) opened at the top of the fixing base 5. When cutting the two straight ends of the lock body 7 (U-shaped rod), the operation of the second electric push rod 605 in the fixing component 6 set inside the fixing groove 501 causes the first arc-shaped clamping plate 601 and the second arc-shaped clamping plate 602 to move, thereby moving the lock body 7 (U-shaped rod). The U-shaped part is clamped and fixed. At the same time, the operation of the third electric push rod 606 causes the first clamping plate 603 and the second clamping plate 604 to move, respectively clamping and fixing the two straight rods of the lock body 7 (U-shaped rod), thereby facilitating the cutting saw blade 401 to cut one end of the straight rod. A moving component 2 is provided on the top of the operating table 1, and a connecting seat 3 is provided on the top of the moving component 2. A hydraulic cylinder 301 is provided on one side of the connecting seat 3, and the output end of the hydraulic cylinder 301 extends out of the other side wall of the connecting seat 3. A first drive motor 4 is connected, and the output end of the first drive motor 4 is connected to a cutting saw blade 401. Through the moving assembly 2, the second drive motor 205 drives the threaded rod 202 to rotate, thereby causing the moving block 203, which is threadedly connected to the threaded rod 202, to move the moving seat 204 and the top assembly of the moving seat 204 (connecting seat 3, hydraulic cylinder 301, first drive motor 4 and cutting saw blade 401) to move. The first drive motor 4 drives the cutting saw blade 401 to rotate, cutting the two straight ends of the lock body 7 (U-shaped rod). The hydraulic cylinder 301 drives the first drive motor 4 and the cutting saw blade 401 to move, and the position can be adjusted according to the cutting size of the two straight ends of the lock body 7 (U-shaped rod). A first electric push rod 8 is provided between the fixed seat 5 and the operating table 1. The height of the fixed seat 5 can be adjusted according to the usage requirements through the operation of the first electric push rod 8, which facilitates better subsequent cutting of the two straight ends of the lock body 7 (U-shaped rod).
