Description
Technical Field
[0001] The invention belongs to the technical field of numerically controlled machine tools, and in particular relates to a shock-resistant CNC numerically controlled machine tool. Background Art
[0002] CNC cutting machines can process workpieces quickly and accurately. Most of the workpieces currently processed by CNC cutting machines are cylindrical metal parts. They are precisely processed by CNC cutting machines. During the processing of flow-type CNC machines, the cylindrical metal parts are input into the CNC machine through the hole in the middle of the main fixture, and then the rotating cylindrical metal parts are processed by cutting components or drilling components. After the workpiece is processed, auxiliary fixtures are usually used to clamp the processed workpiece, and then the metal workpiece is cut off by the cutting component to complete the processing of the metal workpiece. However, Some metal workpieces with longer processing lengths and smaller diameters need to be partially inserted into the auxiliary fixture before being cut, so as to reduce the exposed metal, make the cutting more stable, and avoid damage to the metal workpiece caused by excessive cutting force. After processing, such workpieces usually rely on elastic parts to push out the auxiliary fixture. This method of removing the metal workpiece is not appropriate and can easily cause the metal workpiece to fly out and cause damage. Some also use push rods for movement, which require the addition of electronic control equipment, which undoubtedly increases the complexity of installing wiring between mechanisms and the complexity of the metal workpiece processing program. For this purpose, a CNC machine tool is provided to solve the above problems. Summary of the Invention
[0003] The purpose of the present invention is to provide a shock-resistant CNC machine tool to solve the problems existing in the background technology.

A cylinder 33 fixedly connected to the partition 32 is installed inside the machine tool 1. When the cylinder 33 is started, the partition 32 can be driven to move, so that the collected debris can be discharged and the debris falls into the collection box trolley 34. The collection box trolley 34 can be slid out of the collecting trough 31, which is convenient for the operator to collect and move the debris. The collection box trolley 34 is installed inside the collecting trough 31 for sliding left and right. A bottom trough 41 is provided at the lower end of the machine tool 1, and a rubber base 42 is installed inside the bottom trough 41;
[0027] like Figure 4-6 As shown, the reset assembly includes a piston 15 and a spring 151, an assembly groove 152 is provided in the middle of the left end of the assembly column 141, the piston 15 is sealed and slidably assembled in the assembly groove 152, the spring 151 is fixedly assembled between the right end of the piston 15 and the assembly groove 152, the spring 151 can provide reset elasticity for the piston 15, and a stepped groove 153 connected to the assembly groove 152 is provided at the right end of the assembly column 141. The resistance assembly includes a plurality of spring pieces 16 and a plurality of fan-shaped plates 161. One end of the plurality of spring pieces 16 is evenly fixedly assembled on the inside and outside of the stepped groove 153, and the fan-shaped plate 161 is fixedly assembled at the other end of the spring piece 16. The spring piece 16 can provide fan The fan-shaped plate 161 provides reset elasticity so that the fan-shaped plate 161 is close to the stepped groove 153. Several fan-shaped plates 161 together form a circular plate. The middle part of the fan-shaped plates 161 is provided with an air hole 162. The two sides of the fan-shaped plate 161 are respectively provided with a fan-shaped groove 171 and a fan-shaped piece 172. The fan-shaped plates 161 are buckled with the fan-shaped pieces 172 through the fan-shaped groove 171. A rubber gasket 173 matching the fan-shaped piece 172 is fixedly provided inside the fan-shaped groove 171. A rubber ring 174 is fixedly assembled inside the stepped groove 153. The rubber gasket 173 and the rubber ring 174 can improve the sealing performance. The rubber ring 174 matches the end faces of the fan-shaped plates 161.
[0028] like Figure 4 As shown, the stabilizing component includes a transmission disc 21 and several clamping blocks 22. A transmission groove 23 is opened inside the left side of the assembly column 141, and the transmission disc 21 is rotatably assembled inside the transmission groove 23. A plurality of slide grooves 24 connected to the transmission groove 23 are opened at the left end of the assembly column 141. The clamping block 22 is slidably assembled inside the slide groove 24. Several clamping blocks 22 are transmission-connected to the transmission disc 21, and the transmission disc 21 is transmission-connected to the servo motor 142. A rack 25 is fixedly provided on the right side of the clamping block 22, and a vortex tooth 26 meshing with the rack 25 is assembled on the left side of the transmission disc 21. The rack 25 can be transmitted by rotating the vortex tooth 26, so that the rack 25 moves away from each other, and the meshing of the vortex tooth 26 and the rack 25 can achieve a self-locking effect. An umbrella gear ring 27 is fixedly provided at the right end of the transmission disc 21, and a bevel gear 28 meshing with the bevel gear ring 27 is rotatably assembled inside the transmission groove 23.

[0029] When the auxiliary clamp 14 is used to clamp the workpiece, the machine tool 1 cuts the workpiece through the cutting assembly 12. During the process, the workpiece first enters the assembly groove 152 of the assembly column 141, and the workpiece overcomes the elasticity of the spring 151 to push the piston 15 to move. During the movement of the piston 15, the air is pushed to open the plurality of fan-shaped plates 161 outward. The plurality of fan-shaped plates 161 will not affect the movement of the piston 15 into the assembly groove 152. Then, the servo motor 142 starts the transmission to drive the plurality of clamping blocks 22 to move closer to each other, so that the plurality of clamping blocks 22 clamp the workpiece, shortening the exposed length of the workpiece. The degree of stability of the processed part is improved to avoid damage to the workpiece. Finally, after the cutting of the workpiece is completed, the auxiliary clamp 14 moves away from the main clamp 11, and then the servo motor 142 starts the transmission to drive the several clamping blocks 22 away from each other, thereby releasing the clamping of the workpiece. After the clamping of the workpiece is released, the spring 151 resets and pushes the piston 15 to move. During the process, several fan-shaped plates 161 are pressed tightly so that they only rely on the air holes 162 for air intake, thereby slowing down the retraction speed of the piston 15. In this way, the piston 15 will not push the workpiece quickly, the workpiece will not be ejected, and the workpiece will be avoided from collision damage.
