Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a precision cutting machine. Background Technology

[0002] Precision cutting machines are high-precision processing equipment capable of cutting various materials and playing a vital role in multiple fields. They can be used to process various materials, such as metals, non-metals, plastics, and ceramics.

[0003] Publication No. CN 222643366 U discloses an adjustable precision cutting machine. The workpiece is placed in a placement slot through a through groove. Rotating a knob drives a bidirectional threaded rod to rotate, causing the threaded sleeve to move relative to the workpiece under force. This moves a push-pull rod, which in turn moves a slide rod, which in turn moves a movable clamping plate. The movable clamping plate then moves the workpiece, thus clamping and fixing the workpiece with a fixed clamping plate. This prevents the workpiece from shifting due to force during cutting, improving processing accuracy. This adjustable precision cutting machine has a reasonable structural design, improving processing accuracy and adjustability.

[0004] In the aforementioned precision cutting machine, the workpiece is fixed by rotating the threaded rod to drive the clamping plate. After the workpiece is cut, the threaded rod needs to be rotated again to loosen the clamping plate before the cut workpiece can be removed. The whole operation process is very cumbersome. Before cutting, the threaded rod needs to be rotated to fix the workpiece, and after cutting, the threaded rod needs to be rotated to loosen the workpiece. This results in a long time being spent fixing or loosening the workpiece, which seriously affects work efficiency. Utility Model Content

[0005] (a) Purpose of the utility model

[0006] In view of this, the purpose of this utility model is to propose a precision cutting machine. The technical problem to be solved is that in the existing precision cutting machine, the workpiece is fixed by rotating the threaded rod to drive the clamping plate. After the workpiece is cut, the threaded rod needs to be rotated again to loosen the clamping plate before the cut workpiece can be taken out. The whole operation process is very cumbersome. Before cutting, the threaded rod needs to be rotated to fix the workpiece, and after cutting, the threaded rod needs to be rotated to loosen the workpiece. This results in a long time being spent fixing or loosening the workpiece, which seriously affects work efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above technical objectives, this utility model provides a precision cutting machine:

[0009] It includes a processing table, a vertical plate fixed to the top of the processing table, a horizontal plate fixed to the top of the vertical plate, a hydraulic cylinder installed at the bottom of the horizontal plate, a mounting base fixed to the extended end of the hydraulic cylinder, a precision cutting machine body installed at the bottom of the mounting base, two cylindrical rods slidably connected inside the processing table, a rectangular plate fixed to the top of the cylindrical rods, a connecting plate fixed to one side of the rectangular plate, a screw threaded into the connecting plate, a clamping plate fixed to the bottom of the screw, a U-shaped shelf fixed to the top of the processing table, a through groove opened in the middle of the U-shaped shelf, the through groove being directly below the precision cutting machine body, and a control component for automatically controlling the clamping plate to clamp or release materials at the bottom of the processing table.

[0010] Preferably, a movable plate is fixed to the bottom of both cylindrical rods, a first pressure plate is fixed to the top of the movable plate, a first U-shaped plate is fixed to the bottom of the processing table, and a second pressure plate is slidably connected inside the first U-shaped plate.

[0011] Preferably, the control component includes an extrusion plate that passes through the processing table and slides within it. When the extrusion plate moves downward, it can extrude a second pressure plate and cause the second pressure plate to move. When the second pressure plate moves, it will cause the first pressure plate and the first pressure plate and the moving plate to move downward. A second U-shaped plate is fixed to one side of the vertical plate, and the extrusion plate is slidably fitted within the second U-shaped plate. A long rod is fixed to the top of the extrusion plate, and the end of the long rod away from the extrusion plate is fixed to the mounting base.

[0012] Preferably, a first spring is sleeved on the outer side of the cylindrical rod, one end of the first spring abuts against the rectangular plate, and the other end of the first spring abuts against the processing table.

[0013] Preferably, the top side of the first pressure plate has a first inclined surface, one end of the second pressure plate has a second inclined surface, the second inclined surface and the first inclined surface are arranged in parallel, the other end of the second pressure plate has a third inclined surface, and the bottom side of the extrusion plate has a fourth inclined surface, the third inclined surface and the fourth inclined surface are arranged in parallel.

[0014] Preferably, the first U-shaped plate has a travel groove, and the bottom of the second pressure plate is fixed with a protrusion, which slides within the travel groove.

[0015] Preferably, a guide rod is fixed inside the travel groove, the guide rod passes through the protrusion, the protrusion is slidably fitted outside the guide rod, and a second spring is sleeved on the outside of the guide rod, one end of the second spring abuts against the protrusion, and the other end of the second spring abuts against the inner wall of the travel groove.

[0016] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0017] 1. When the hydraulic cylinder extends, it drives the precision cutting machine body and the extrusion plate downwards. As the extrusion plate moves downwards, it presses against the second pressure plate and causes it to move. The movement of the second pressure plate presses against the first pressure plate and causes the first pressure plate, cylindrical rod, rectangular plate, and clamping plate to move downwards, thus clamping the workpiece onto the U-shaped shelf. Because the workpiece is clamped between the clamping plate and the U-shaped shelf, the processing accuracy is improved. This process is automatic. After the workpiece is cut, the hydraulic cylinder retracts, causing the precision cutting machine body and the extrusion plate to move upwards. When the extrusion plate moves upwards and no longer presses against the second pressure plate... When the first pressure plate is pressed, the second pressure plate moves away from the first pressure plate under the return force of the second spring. When the second pressure plate stops pressing the first pressure plate, the connecting plate and clamping plate move upward under the return force of the first spring, so that the clamping plate no longer clamps the workpiece. This process is completed after the cutting is finished, and the workpiece is automatically released without manual operation, which makes the operation more convenient. That is, the workpiece is automatically switched according to the working state of the precision cutting machine body when it is fixed or released, without the need for manual operation, saving the time of fixing or releasing the workpiece and improving work efficiency.

[0018] 2: Since the workpieces have different thicknesses, the distance between the clamping plate and the U-shaped shelf can be adjusted by rotating the screw, which can meet the processing needs of workpieces of different thicknesses. Attached Figure Description

[0025] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0026] Reference Figure 1-4 :

[0027] In one embodiment of this utility model, a precision cutting machine is provided, including a processing table 1. A vertical plate 2 is fixed to the top of the processing table 1, and a horizontal plate 3 is fixed to the top of the vertical plate 2. A hydraulic cylinder 4 is installed at the bottom of the horizontal plate 3. A mounting base 5 is fixed to the extended end of the hydraulic cylinder 4. A precision cutting machine body 6 is installed at the bottom of the mounting base 5. Two cylindrical rods 7 are slidably connected inside the processing table 1. A rectangular plate 8 is fixed to the top of the cylindrical rods 7. A connecting plate 9 is fixed to one side of the rectangular plate 8. A screw 10 is threadedly connected to the connecting plate 9. A clamping plate 11 is fixed to the bottom of the screw 10. A U-shaped shelf 12 is fixed to the top of the processing table 1. A through groove 13 is opened in the middle of the U-shaped shelf 12. The through groove 13 is located directly below the precision cutting machine body 6. A control component for automatically controlling the clamping plate 11 to clamp or release materials is provided at the bottom of the processing table 1.

[0028] It should be noted that the hydraulic cylinder 4 and the precision cutting machine body 6 in this embodiment are both conventional equipment known to those skilled in the art and can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structure and function. Their setting method, installation method and electrical connection method can be adjusted and operated by those skilled in the art according to the requirements of their instruction manual, and will not be described in detail here.

[0029] Among them, the bottom of the two cylindrical rods 7 are jointly fixed with a movable plate 14, the top of the movable plate 14 is fixed with a first pressure plate 15, the bottom of the processing table 1 is fixed with a first U-shaped plate 16, and the second pressure plate 17 is slidably connected inside the first U-shaped plate 16.

[0030] In addition, the control components include an extrusion plate 20, which passes through the processing table 1 and slides within it. When the extrusion plate 20 moves downward, it can extrude the second pressure plate 17 and drive the second pressure plate 17 to move. When the second pressure plate 17 moves, it will drive the first pressure plate 15 and the moving plate 14 to move downward. A second U-shaped plate 18 is fixed to one side of the vertical plate 2, and the extrusion plate 20 is slidably fitted within the second U-shaped plate 18. A long rod 19 is fixed to the top of the extrusion plate 20, and the end of the long rod 19 away from the extrusion plate 20 is connected to the mounting plate 14. The mounting base 5 is fixed in place. A first spring 29 is sleeved on the outside of the cylindrical rod 7. One end of the first spring 29 abuts against the rectangular plate 8, and the other end of the first spring 29 abuts against the processing table 1. The top side of the first pressure plate 15 forms a first inclined surface 21. One end of the second pressure plate 17 forms a second inclined surface 22. The second inclined surface 22 and the first inclined surface 21 are arranged in parallel. The other end of the second pressure plate 17 forms a third inclined surface 23. The bottom side of the extrusion plate 20 forms a fourth inclined surface 24. The third inclined surface 23 and the fourth inclined surface 24 are arranged in parallel.

[0031] In use, place the workpiece to be cut on the U-shaped shelf 12, and then start the hydraulic cylinder 4 and the precision cutting machine body 6. When the hydraulic cylinder 4 extends, it drives the mounting base 5 and the precision cutting machine body 6 to move down. When the mounting base 5 moves down, it drives the long rod 19 and the extrusion plate 20 to move down. When the extrusion plate 20 moves down, the fourth inclined surface 24 of the extrusion plate 20 presses the third inclined surface 23 of the second pressure plate 17, thereby driving the second pressure plate 17 to move. When the second pressure plate 17 moves, the second inclined surface 22 at one end of it will press the first inclined surface 21 of the first pressure plate 15, and drive the first pressure plate 15 to move down. When the first pressure plate 15 moves down, it drives the moving plate 14 to move down. When the moving plate 14 moves down, it drives the cylindrical rod 7 and the rectangular plate 8 to move down. When the rectangular plate 8 moves down, it drives the connecting plate 9, the screw 10 and the clamping plate 11 to move down, so that the clamping plate 11 clamps the workpiece on the U-shaped shelf 12.

[0032] Then, the hydraulic cylinder 4 continues to extend, causing the extrusion plate 20 to continue moving downwards. The second pressure plate 17 moves out from the fourth inclined surface 24. At this point, the second pressure plate 17 and the vertical surface of the extrusion plate 20 are in contact. When the extrusion plate 20 continues to move downwards, it will no longer press the second pressure plate 17, meaning the second pressure plate 17 will no longer move. After the second pressure plate 17 moves out from the fourth inclined surface 24, the first pressure plate 15 moves out from the second inclined surface 22, causing the top of the first pressure plate 15 and the bottom of the second pressure plate 17 to come into contact. After the second pressure plate 17 and the vertical surface of the extrusion plate 20 are in contact, the second pressure plate 17 will no longer move, thus preventing the second pressure plate 17 from pressing the first pressure plate 15. That is, the first pressure plate 15 will not move down any further. Thus, when the clamping plate 11 clamps the workpiece onto the U-shaped shelf 12, and the hydraulic cylinder 4 continues to extend to drive the extrusion plate 20 and the precision cutting machine body 6 to move down, the clamping plate 11 will not move down any further after clamping and fixing the workpiece, while the precision cutting machine body 6 will continue to move down and cut the workpiece. Since the workpiece is clamped between the clamping plate 11 and the U-shaped shelf 12, the processing accuracy is improved. Moreover, this process automatically clamps the workpiece before the precision cutting machine body 6 cuts as the hydraulic cylinder 4 extends. Compared with the prior art, which uses the rotating threaded rod to drive the clamping plate for clamping and fixing, the process of fixing the workpiece in this embodiment is more convenient.

[0033] In addition, a travel groove 25 is provided in the first U-shaped plate 16, and a protrusion 27 is fixed at the bottom of the second pressure plate 17. The protrusion 27 is slidably fitted in the travel groove 25. A guide rod 26 is fixed in the travel groove 25. The guide rod 26 passes through the protrusion 27. The protrusion 27 is slidably fitted outside the guide rod 26. A second spring 28 is sleeved on the outside of the guide rod 26. One end of the second spring 28 abuts against the protrusion 27, and the other end of the second spring 28 abuts against the inner wall of the travel groove 25.

[0034] It should be noted that after the workpiece is cut, the hydraulic cylinder 4 retracts, causing the mounting base 5 and the precision cutting machine body 6 to move upward, which in turn causes the long rod 19 and the extrusion plate 20 to move upward. When the extrusion plate 20 moves upward and no longer extrudes the second pressure plate 17, the second pressure plate 17 moves away from the first pressure plate 15 under the rebound force of the second spring 28. When the second pressure plate 17 no longer extrudes the first pressure plate 15, the connecting plate 9 and the clamping plate 11 move upward under the rebound force of the first spring 29, so that the clamping plate 11 no longer clamps the workpiece. This process occurs when the hydraulic cylinder 4 moves the precision cutting machine body 6 upward after the cutting is completed, and the workpiece is automatically released without manual operation, making the operation more convenient. It is worth mentioning that, since the thickness of the workpiece varies, the distance between the clamping plate 11 and the U-shaped shelf 12 can be adjusted by rotating the screw 10, which can meet the processing needs of workpieces of different thicknesses.

[0035] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
