DETAILED DESCRIPTION

[0027] 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 of the embodiments.

[0028] Reference Figure 1-Figure 4 A shockproof CNC machine tool for crusher shell processing includes a shell 1, a movable platform 6 is arranged inside the shell 1, and the movable platform 6 is connected to the shell 1 through a driving mechanism. A tool holder 2 is installed on the top of the movable platform 6, and a chuck 23 is installed at one end inside the shell 1. The chuck 23 is one of a three-jaw chuck, a four-jaw chuck or a five-jaw chuck. The workpiece can be clamped and fixed by the chuck 23, and then the tool is installed on the tool holder 2. Then, the driving mechanism is used to control the rotation of the chuck 23 and the actual tool is in contact with the workpiece to process the workpiece.

[0029] It should be noted that if Figure 1 As shown, a protective cover 4 is provided on the side of the shell 1 close to the opening, and the side of the protective cover 4 is connected to the guide rail fixed on the shell 1 through a slider, and the protective cover 4 covers the opening of the shell 1. In actual use, the protective cover 4 can be covered on the opening of the shell 1 to block the opening of the shell 1, so that debris during the processing will not splash to the outside of the shell 1.

[0030] like Figure 1 and Figure 2As shown, strip fixing plates 5 are installed on both sides of the bottom of the shell 1, and a supporting base plate 10 is provided at the bottom of each strip fixing plate 5. First dampers 16 are installed at both ends of the bottom of the strip fixing plates 5, and the bottom of the first damper 16 is fixed to the top of the supporting base plate 10, and the side of each first damper 16 is sleeved with a second spring 18, and the bottom of the second spring 18 is fixed to the top of the supporting base plate 10, and the top of the second spring 18 is fixed to the strip fixing plate 5. The shell 1 can be buffered by the first damper 16 and the second spring 18, so that the shell 1 will not be affected by external vibration during the processing.

[0031] like Figure 1 and Figure 2 As shown, a mounting seat 14 is symmetrically installed on the top of each supporting base plate 10, a second damper 19 is installed on the adjacent surface of each pair of mounting seats 14, a fixing block 12 is installed on the adjacent end of the second damper 19, one side of each fixing block 12 is connected to a connecting rod 11 through a hinge seat, the top of the connecting rod 11 is rotatably connected to the bottom of the strip fixing plate 5, and a first spring 13 is installed on the side of each second damper 19, one end of each first spring 13 is fixed on the side of the mounting seat 14, and the other end of each first spring 13 is fixed on the side of the fixing block 12. In actual use, when the first damper 16 and the second spring 18 buffer the shell 1, the supporting base plate 10 will synchronously squeeze the connecting rod 11 under the influence of external vibration, so that the connecting rod 11 will rotate under the force, squeezing the second damper 19 and the first spring 13, and the second damper 19 and the first spring 13 will perform secondary buffering on the shell 1, further improving the stability of the shell 1.

[0032] like Figure 2 and Figure 3 As shown, a slag discharge groove 27 is provided on one side of the shell 1, and fixed seats 22 are installed on the side of the shell 1 and at both ends of the slag discharge groove 27. A rotating shaft 3 is rotatably connected between the fixed seats 22 and inside the shell 1. The rotating shafts 3 are connected by a conveyor mesh belt 21, and the conveyor mesh belt 21 is located below the tool holder 2. One end of one of the rotating shafts 3 is connected to a drive motor 17. An installation box 7 is installed on one side of the shell 1, and the drive motor 17 is installed on the side wall of the installation box 7. In actual use, the debris generated during the processing will fall on the conveyor mesh belt 21 under the impact of the coolant, and the coolant passes through the conveyor mesh belt 21 to flow to the bottom of the shell 1, while the debris generated during the processing will remain on the conveyor mesh belt 21. The drive motor 17 can drive the conveyor mesh belt 21 to move and discharge the debris from the shell 1.

[0033] It should be noted that if Figure 3 and Figure 4As shown, the conveyor mesh belt 21 is arranged to be inclined upward, and a plurality of strip baffles 26 are equidistantly installed on the outer surface of the conveyor mesh belt 21. Under the action of gravity, the coolant will flow along the conveyor mesh belt 21 toward the bottom end of the conveyor mesh belt 21, so as to prevent the coolant from being discharged from the shell 1 from the conveyor mesh belt 21, and the impurities in the coolant can be blocked under the action of the strip baffles 26, and the impurities in the coolant follow the coolant to flow from the gap between the bottom end of the conveyor mesh belt 21 and the outer shell 1 to the bottom of the shell 1.

[0034] It should be noted that a drain pipe 15 is installed at the bottom of the shell 1, a valve is installed on the drain pipe 15, and one end of the drain pipe 15 is connected to the delivery pump. In actual use, the valve can be opened, and then the coolant in the shell 1 can be discharged through the drain pipe 15 by the delivery pump to avoid the coolant accumulating inside the shell 1.

[0035] like Figure 2 and Figure 3 As shown, a strip bottom plate 9 is installed between one end of the two supporting bottom plates 10, a collecting box 8 is provided on the top of the strip bottom plate 9, and one end of the conveyor mesh belt 21 extends above the collecting box 8. During actual use, the debris discharged by the conveyor mesh belt 21 will fall into the collecting box 8 for centralized collection.

[0036] Specifically, when the utility model is in use, when external vibration occurs, the support base plate 10 is affected by the external force and vibrates, which can cause extrusion to the first damper 16 and the connecting rod 11. The deformation of the first damper 16 under force will cause extrusion to the second spring 18. The first damper 16 and the second spring 18 can be used to initially buffer and eliminate the impact force. At the same time, the connecting rod 11 is rotated under force, causing extrusion to the second damper 19 and the first spring 13. Under the action of the second damper 19 and the first spring 13, the impact force can be secondary buffered and eliminated, thereby buffering and protecting the shell 1, so that the shell 1 remains stable and the use effect is improved. In the process of processing the crusher shell, the coolant and debris will flow to the conveyor mesh belt 21 under the action of gravity. The coolant can pass through the conveyor mesh belt 21 and flow to the bottom of the shell 1. At the same time, the drive motor 17 is controlled to work, and the drive motor 17 can drive the conveyor mesh belt 21 to rotate, so that the impurities filtered by the conveyor mesh belt 21 are transported to the outside of the shell 1 and fall into the collection box 8 for collection, which is convenient for cleaning.

[0037] Furthermore, Figure 2 and Figure 3 As shown, a guide plate 20 is installed on the side of the shell 1, and the guide plate 20 is located below the slag discharge chute 27, and one end of the guide plate 20 extends to the top of the collection box 8. The guide plate 20 is set to be inclined downward, and the guide plate 20 is set in an arc shape. Through the guide plate 20, the debris transported by the conveyor belt 21 can be guided, and the debris can fall into the collection box 8 along the guide plate 20.

[0038] Furthermore, Figure 4 As shown, a plurality of support shafts 25 are provided inside the conveyor mesh belt 21, and both ends of the support shafts 25 are rotatably connected to the side walls of the shell 1. The support shafts 25 can support the conveyor mesh belt 21 so that the conveyor mesh belt 21 can work normally.

[0039] Furthermore, Figure 3 As shown, a guide plate 24 is installed on the inner side wall of the shell 1, the top of the guide plate 24 is inclined, and one end of the guide plate 24 extends above the conveyor mesh belt 21. Under the action of the guide plate 24, the coolant can be guided so that the coolant will flow to the guide plate 24 after cooling the workpiece, and flow along the guide plate 24 to the conveyor mesh belt 21.

[0040] Furthermore, a buffer gasket is installed at the bottom of the support base plate 10. The buffer gasket is made of rubber material or other materials with buffering properties. The buffer gasket can buffer the support base plate 10 and the ground, further improving the buffering effect.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
