Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a milling machine fixture that can be used for a numerically controlled milling machine. Background Art

[0002] Securely clamping the workpiece is crucial during CNC milling operations. This is because only with secure clamping can the desired precision and quality be effectively achieved. However, through practical application and observation, we've discovered that existing milling machine fixtures exhibit a number of significant shortcomings.

[0003] First, existing milling machine fixtures have obvious limitations in adapting to workpieces of different sizes. They are often difficult to adjust flexibly and cannot meet the clamping needs of workpieces with large differences in size. This means that when facing workpieces of different sizes, it may be necessary to frequently replace fixtures of different specifications, which not only increases the complexity of the operation, but also greatly reduces processing efficiency and increases production costs. Secondly, the convenience of clamping operations is also lacking. When clamping, existing fixtures may require operators to perform a series of complex manual adjustments and operations, which are not intelligent and automated enough. This not only increases the workload of operators, but also easily affects the clamping effect and processing accuracy due to errors and instability in human operations. In the modern manufacturing industry that pursues efficient production, this inconvenient clamping operation is obviously no longer able to meet production needs. Therefore, a milling machine fixture that can be used for CNC milling machines is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-4 A milling machine fixture that can be used for a CNC milling machine includes a fixed seat 1 and a movable seat 2. A rotating chamber 11 and an equipment chamber 13 are provided inside the fixed seat 1. A movable screw 12 is provided in the rotating chamber 11. A movable motor 14 connected to the movable screw 12 is provided in the equipment chamber 13. The movable seat 2 is connected to the movable screw 12 through a connecting mechanism. A mounting rod 6 is provided on both the fixed seat 1 and the movable seat 2 through an opening 3. Two rotating grooves 9 are provided on the upper end surface of the mounting rod 6. A double-headed screw 10 is provided in the two rotating grooves 9 for rotating together. A movable rod 7 is provided on a threaded sleeve of the double-headed screw 10, and a clamping block 8 is installed on the movable rod 7.

[0024] The connecting mechanism includes a connecting frame 4 threadedly mounted on a double-headed screw 10. The fixed seat 1 is provided with an opening 3 corresponding to the connecting frame 4. The connecting frame 4 is fixedly connected to the movable seat 2. The above opening 3 is designed for the connection frame 4 to move.

[0025] A first limit rod is provided in the rotating chamber 11. The first limit rod is parallel to the moving screw 12. The first limit rod slides through the connecting frame 4. The above-mentioned first limit rod is located directly below the moving screw 12, which realizes the movement limit of the connecting frame 4 and prevents the connecting frame 4 from rotating with the moving screw 12.

[0026] A second limiting rod 16 is provided in the rotating groove 9. The second limiting rod 16 is parallel to the double-headed screw 10. The second limiting rod 16 slides through the movable rod 7. The above-mentioned second limiting rod 16 is located directly below the double-headed screw 10, which realizes the limitation of the movable rod 7 and prevents it from rotating with the double-headed screw 10.

[0027] A protective pad is provided on the surface of the clamping block 8. The protective pad is made of rubber and has anti-slip grooves on the surface of the protective pad. The protective pad can effectively avoid damage to the surface of the clamped object.

[0028] A heat dissipation port connected to the equipment cavity 13 is provided on the side wall of the fixing base 1. A protective net is provided inside the heat dissipation port. The heat dissipation port facilitates heat dissipation when the movable motor 14 is working. The protective net can effectively prevent external dust and impurities from entering and affecting the movable motor 14.

[0029] When the present invention is in use, components such as the fixed seat 1 and the movable seat 2 are placed on the processing platform of the CNC milling machine, and the fixed seat 1 is fixedly placed on the movable seat 2 and is movably set. The object to be processed is placed on the fixed seat 1 and the movable seat 2 together, and needs to be fixed before processing. At this time, starting the adjustment motor 15 can drive the double-headed screw 10 to rotate. When the double-headed screw 10 rotates, the movable rod 7 will move, thereby driving the clamping block 8 to move to complete the clamping and fixing operation of the object to be processed, and the spacing of the corresponding clamping blocks 8 can be adjusted according to the size of the object to be processed.

[0030] In this solution, after starting the moving motor 14, the moving screw 12 can be driven to rotate. When the moving screw 12 rotates, the connecting frame 4 will drive the movable seat 2 to move closer to or away from the fixed seat 1, thereby adjusting the spacing of the movable rod 7 to adapt to different sizes of objects to be processed.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
