DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] Depend on Figure 1-4 Provided is a high-rigidity, vibration-resistant CNC lathe base, comprising a base substrate 1;

[0025] The upper end surface of the base substrate 1 is rectangular and is provided with four groups of first buffer components 2, and the four groups of first buffer components 2 are jointly supported and provided with a lathe top plate 4; in actual use, in order to improve the anti-vibration and anti-tensile use effect of the lathe top plate 4, the lathe top plate 4 is made of a high-rigidity metal component, which can maintain a stable shape when subjected to force, is not prone to deformation or has extremely small deformation, thereby achieving stable anti-vibration use of the lathe top plate 4;

[0026] Two sets of second anti-vibration components 3 are also provided on the lower end surface of the lathe top plate 4;

[0027] The two groups of second anti-vibration components 3 each include two connecting seats 31 arranged on the lower end surface of the lathe top plate 4. The two connecting seats 31 are arranged in parallel. The lower end surfaces of the two connecting seats 31 are rotatably connected with connecting plates 32. A disc spring group 33 is welded between the two connecting plates 32, and a secondary spring 34 is welded at the bottom of the disc spring group 33.

[0028] In this embodiment, in actual use, the second anti-vibration component 3 and the first buffer component 2 can effectively absorb and reduce the vibration energy on the lathe top plate 4. The auxiliary spring 34 and the disc spring group 33 can absorb and disperse the vibration energy through their elastic characteristics, while the first buffer component 2 slows down the transmission of vibration through the damping effect of oil. Through the coordinated use of the two, the impact of the vibration generated by the lathe top plate 4 during processing on the ground or surrounding equipment can be significantly reduced.

[0029] Specifically, refer to Figure 2-3 The disc spring group 33 and the auxiliary spring 34 are both metal parts and are arranged in an arc-shaped sheet shape as a whole. The auxiliary spring 34 is arranged vertically and horizontally with the center point of the disc spring group 33.

[0030] In this embodiment, in actual use, when the lathe top plate 4 is moved due to the downward pressure of the workpiece, the lathe top plate 4 will limit the connecting seat 31 and move it downward. When the connecting seat 31 moves downward, the disc spring group 33 and the auxiliary spring 34 arranged between the two connecting seats 31 will be deformed, and then the lathe top plate 4 is buffered and vibration-proofed through the deformation of the disc spring group 33 and the auxiliary spring 34. Since both are metal parts and are arranged in arc sheets, they can effectively absorb and disperse vibration energy, thereby reducing the impact of the lathe top plate 4 on the equipment when carrying the workpiece and performing processing.

[0031] Specifically, refer to Figure 2-3 A connecting lock plate 35 is arranged outside the center point of the disc spring group 33 and the auxiliary spring 34, and an extension shaft 36 is rotatably arranged between the connecting lock plates 35 of the two sets of second anti-vibration components 3. Lock rings are arranged at both ends of the extension shaft 36 for limiting the side of the connecting lock plate 35.

[0032] In this embodiment, the connecting lock plate 35 and the extension shaft 36 can be used to limit the disc spring group 33 and the auxiliary spring 34 in the two groups of second anti-vibration components 3, so that the two groups of second anti-vibration components 3 can maintain synchronous displacement, and then cooperate with each other to complete the anti-vibration use of the lathe top plate 4, and the locking ring arranged at the end of the extension shaft 36 can prevent the connecting lock plate 35 from slipping.

[0033] Specifically, refer to Figure 2 , Figure 4 Each group of first buffer components 2 includes a bottom limit seat 21 arranged on the upper end surface of the base substrate 1, and a hydraulic buffer 22 is arranged on the bottom limit seat 21. A buffer shaft 25 extends from the top end of the hydraulic buffer 22.

[0034] In this embodiment, in actual use, when the lathe top plate 4 is pressed downward by the workpiece, the four groups of first buffer components 2 will first absorb and buffer the downward pressure of the lathe top plate 4. At this time, when the lathe top plate 4 is pressed downward, it presses the buffer shaft 25 downward, causing the oil pressure buffer 22 to take effect. The oil pressure buffer 22 can slow down the transmission of vibration through the damping effect of the oil.

[0035] Specifically, refer to Figure 1-2 , Figure 4 Through holes are provided at the four corners of the top plate 4 of the lathe, penetrating the upper and lower sides thereof. The buffer shaft 25 in each group of the first buffer components 2 corresponds to one of the through holes and is embedded therein.

[0036] In this embodiment, the buffer shaft 25 can produce synchronous downward pressure following the downward pressure of the lathe top plate 4. At this time, the buffer shaft 25 will drive the oil in the hydraulic buffer 22 to produce a damping and buffering effect, thereby realizing the buffering and anti-vibration use of the lathe top plate 4 by the four groups of first buffer components 2.

[0037] Specifically, refer to Figure 4 The outer sleeve of the oil pressure buffer 22 is provided with a compression spring 23 and a limit ring 24, the compression spring 23 is arranged between the bottom limit seat 21 and the limit ring 24, and a gasket is also fixed on the outside of the oil pressure buffer 22 to limit the limit ring 24 to the outside of the oil pressure buffer 22.

[0038] In this embodiment, in actual use, when the lathe top plate 4 is pressed downward by the workpiece, the four groups of first buffer components 2 will first absorb and buffer the downward pressure of the lathe top plate 4. At this time, the downward pressure of the lathe top plate 4 will limit the limit ring 24 to follow the downward pressure. When the limit ring 24 is pressed downward, the compression spring 23 will be deformed and absorb the downward pressure of the lathe top plate 4. At the same time, the oil pressure buffer 22 will absorb the downward pressure of the lathe top plate 4 for a second time, thereby further buffering the lathe top plate 4.

[0039] The high rigidity and vibration-resistant CNC lathe base of this utility model:

[0040] Step 1: In actual use, when the operator needs to perform rough processing on the workpiece, the workpiece to be processed can be placed on the upper end surface of the lathe top plate 4. At this time, when the lathe top plate 4 is pressed down by the workpiece, the four sets of first buffer components 2 will first absorb and buffer the downward pressure of the lathe top plate 4. At this time, the downward pressure of the lathe top plate 4 will limit the limit ring 24 to follow the downward pressure. When the limit ring 24 is pressed down, the compression spring 23 will be deformed and absorb the downward pressure of the lathe top plate 4. At the same time, the oil pressure buffer 22 will absorb the downward pressure of the lathe top plate 4 for a second time, thereby further buffering the lathe top plate 4.

[0041] Step 2: When the lathe top plate 4 is processing and generates amplitude, the first buffer component 2 will initially buffer and protect the vibration force and downward pressure generated by the lathe top plate 4, and when the mass of the workpiece is too large and causes the downward pressure of the lathe top plate 4 to exceed the buffering threshold of the first buffer component 2, the second anti-vibration component 3 arranged under the lathe top plate 4 will perform a second buffering and anti-vibration protection on the lathe top plate 4. During this period, when the lathe top plate 4 is moved by the downward pressure of the workpiece, the lathe top plate 4 will limit the connecting seat 31 and move it downward. When the connecting seat 31 moves downward, the disc spring group 33 and the auxiliary spring 34 arranged between the two connecting seats 31 will be deformed, and the connecting lock plate 35 will limit the auxiliary spring 34 and the disc spring group 33, and then the lathe top plate 4 will be further buffered and protected by the deformation of the disc spring group 33 and the auxiliary spring 34, so as to avoid the lathe top plate 4 being pressed down too far due to the excessive mass of the workpiece. At the same time, through the deformation return of the second anti-vibration component 3, the first buffer component 2 can be cooperated with the lathe top plate 4 to perform a large amount of anti-vibration buffering, thereby further improving the anti-vibration effect of the lathe top plate 4.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
