[0002] CNC machining refers to a process method for processing parts on CNC machine tools. When processing parts on CNC machine tools, the first thing to solve is the clamping and fixation of the parts. The function of the CNC fixture is to position the workpiece and clamp the workpiece reliably for subsequent processing.

[0003] However, there are still some problems in the use of CNC fixtures. That is, the existing CNC fixtures are usually detachable from the machine tools. The detachable type makes it easy for personnel to replace the CNC fixtures and clean the machine tools. However, when the CNC fixtures need to be installed on the machine tools in the future, a certain amount of bolts and extrusion blocks are used to cooperate so that the CNC fixtures can be installed in position. This method is not convenient for personnel to operate and install, and the installation and disassembly are more cumbersome. For this reason, we propose a CNC fixture that is easy to install to solve the above problems. Utility Model Content

The box body 4 is fixedly installed on the outside of the fixture plate 3, so that when the worm 6 rotates in the inner cavity 5, it can drive the two worm wheels 7 to rotate in opposite directions, that is, the worm wheel 7 can drive the gear bar 9 to move, so that the extrusion block 10 fixedly installed at the bottom end of the gear bar 9 can be close to the T-shaped plate 2. The outer side of the clamp plate 3 is provided with a self-locking property through the worm 6 and the worm wheel 7, thereby the clamp plate 3 can be directly and quickly fixedly installed on the top of the T-shaped plate 2. The structure is simple to operate and can directly install the clamp plate 3. The box body 4 is located at the center of the outer side of the clamp plate 3, and the worm 6 is located at the center of the inner cavity 5. The gear bar 9 is against the inner wall of the inner cavity 5, so that the personnel can rotate the worm 6. At the same time, the gear bar 9 is stably moved inside the inner cavity 5, and the inner wall of the inner cavity 5 is fixed. A limit plate 12 is installed, and two groups of the limit plates 12 are provided. The two groups of limit plates 12 are symmetrically located at both sides of the gear bar 9, and the two groups of limit plates 12 are in contact with the outer side of the gear bar 9. By providing the limit plates 12, the position of the gear bar 9 can be further limited, so that the extrusion block 10 can move smoothly in the limit hole 11. A torsion block 13 is fixedly installed on the top of the worm 6. By providing the torsion block 13, it is convenient for personnel to rotate the position of the worm 6.

[0022] like Figure 3 and Figure 4 As shown, a sealing plug 14 is fixedly installed on the outside of the extrusion block 10, and the sealing plug 14 is located between the T-shaped plates 2. The sealing plug 14 is tightly attached to the outside of the T-shaped plates 2. An L-shaped plate 15 is fixedly installed on the top of the sealing plug 14, and the L-shaped plate 15 is in contact with the outside of the box body 4. One side of the L-shaped plate 15 is set in an arc shape. The sealing plug 14 is made of rubber material. By providing the cooperation between the sealing plug 14 and the L-shaped plate 15, the extrusion block 10 is located between the T-shaped plates 2. After fixing the position of the fixture plate 3, the sealing plug 14 can be inserted between the T-shaped plates 2, so that the extrusion block 10 can be hidden to prevent During the processing of the workpiece on the fixture plate 3, the generated debris is between the T-shaped plates 2, which affects the subsequent personnel's movement of the extrusion block 10 from between the T-shaped plates 2. At the same time, the sealing plug 14 is taken out first to push the debris out from between the T-shaped plates 2. A magnetic sheet 16 is fixedly installed on the L-shaped plate 15, and the magnetic sheet 16 is located at the center position of the outer side of the L-shaped plate 15.

[0023] The utility model provides a CNC fixture that is easy to install, and the specific working principle is as follows:

[0024] When the device is in use, the clamp plate 3 is placed at the top position of the T-plate 2 for pushing work. During this period, the extrusion block 10 can slide at the position between the T-plates 2, and the pushing of the clamp plate 3 is stopped. The personnel rotates the torsion block 13 to make the worm 6 rotate in the inner cavity 5, so that the worm 6 can drive the two worm wheels 7 to mesh and rotate, so that the worm wheel 7 can drive the gear bar 9 to move, and the gear bar 9 can drive the extrusion block 10. During this period, the extrusion block 10 is in the limiting hole 11 and slides, so that the extrusion block 10 can be tightly attached to the outer side of the T-plate 2. The self-locking property between the worm 6 and the worm wheel 7 can fix the position of the clamp plate 3 at the top position of the T-plate 2. Subsequently, the sealing plug 14 can be inserted between the T-plates 2 for pushing, so that the sealing plug 14 abuts against the outer side of the extrusion block 10 and the L-shaped plate 15 abuts against the outer side of the box body 4, thereby hiding the extrusion block 10.
