Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of numerical control machine tools, in particular to a reverse buckle double gold vibration absorbing pad seat with adjustable reverse vibration structure. BACKGROUND

[0002] Nowadays, the production and processing of parts are mainly carried out through numerical control machine tools and automatic production line equipment. When numerical control machining is carried out, the vibration generated by the numerical control machine tool will have a great influence on the precision of the parts. Therefore, reducing the vibration of the numerical control machine tool is an important prerequisite for ensuring the precision of the parts. The general machine tool base structure can realize functions such as bearing and leveling, but the vibration reduction effect is limited.

[0003] Chinese patent CN209936477U discloses a reverse buckle double gold vibration absorbing pad seat, which comprises a base, an upper cover horizontally arranged above the base, a vibration absorbing mounting area formed between the lower end surface of the upper cover and the upper end surface of the base, and a machine pad foot supported by the upper end surface of the upper cover. An adjusting rod penetrates the upper cover and is connected with the base, and the part above the upper cover forms a reverse vibration mounting area. A gasket vibration absorbing assembly is arranged in the vibration absorbing mounting area, which comprises a first vibration absorbing gasket symmetrically arranged on the adjusting rod and a second vibration absorbing gasket arranged between the first vibration absorbing gaskets. A reverse vibration assembly is installed in the reverse vibration mounting area, which is arranged on the adjusting rod, and the lower end of the reverse vibration assembly is in contact with the machine pad foot. The adjusting rod penetrating the upper cover can be directly connected with the machine pad foot of the numerical control machine tool, solving the technical problem that the existing gap eliminator cannot be perfectly connected with the numerical control machine tool, improving the vibration reduction effect of the numerical control machine tool, and ensuring better machining precision.

[0004] However, in the technical solution, the technical problem that the existing gap eliminator cannot be perfectly connected with the numerical control machine tool is effectively solved.

[0047] Embodiment one

[0048] As shown in Figs. 1-3 The present embodiment provides a double gold anti-vibration pad seat with adjustable anti-vibration structure, which comprises a base 1, an upper cover 2 and a pad vibration damping assembly 3 arranged between one side of the base 1 and the upper cover 2.

[0056] Further, the adjusting sleeve 51 is further matched with an adjusting nut 52, the adjusting nut 52 adjusts the distance between the machine tool foot 10 and the upper cover 2.

[0057] As an improvement, the anti-vibration elimination assembly 4 comprises:

[0058] a pressing plate assembly 42;

[0059] an anti-vibration absorbing assembly 43, the top end of which is connected with the pressing plate assembly 42, and the bottom end is installed on the base 1; and

[0060] a support 44 which is arranged between the gasket vibration elimination assembly 3 and the anti-vibration absorbing assembly 43, and the upper end of which is rotationally connected with the pressing plate assembly 42;

[0061] The anti-vibration absorbing assembly 43 drives the pressing plate assembly 42 to float through its own deformation, dissipates the anti-vibration force conducted by the pressing plate assembly 42, and makes the other end of the pressing plate assembly 42 abut against the machine tool foot 10.

[0062] Preferably, the pressing plate assembly 42 comprises:

[0063] a pressing plate 422 which is rotationally installed on the top end of the support 44; and

[0064] a positioning member 423 which is installed below the pressing plate 422, and the bottom thereof is in arc surface contact abutting and matching abutment between the machine tool foot 10.

[0065] Preferably, the bottom of the positioning member 423 is an arc positioning convex 4231 which is matched with the arc positioning portion 101 opened on the upper end surface of the machine tool foot 10, and the arc positioning convex 4231 preferably adopts a spherical structure.

[0072] Example 2

[0073] like Fig. 2 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0074] In this embodiment, the deformation component 431 includes an elastic element 431a installed between the base 1 and the upper positioning member 434. One end of the elastic element 431a is connected to the pressure plate 422, and the other end is connected to the base 1. The elastic element 431a is preferably a spring.

[0075] It should be noted that the adjusting member 432 abuts against the upper positioning member 434. The adjusting member 432 presses the upper positioning member 434, causing the upper positioning member 434 to press the elastic member 431a, thereby changing the extension and retraction length of the elastic member 431a and thus changing the elastic force of the elastic member 431a.

[0076] Preferably, the bottom of the elastic member 431a is further provided with a lower positioning member 433a, the lower positioning member 433a is connected to the base 1, the elastic member 431a is sleeved on the lower positioning member 433a, and the top of the elastic member 431a is sleeved on the outside of the upper positioning member 434.

[0077] It should be noted that the shim damping assembly 3 needs to be pre-tightened to ensure that the first damping shim 31 and the second damping shim 32 are completely fitted together. By adjusting the adjusting member 432 to compress the elastic member 431a, the elastic force of the elastic member 431a is increased, thereby squeezing the shim damping assembly 3 and completing the pre-run-in of the shim damping assembly 3. This ensures that the first damping shim 31 and the second damping shim 32 in the shim damping assembly 3 are completely fitted together without gaps, reducing the occurrence of unstable operation of the machine tool due to gaps during operation.

[0078] During the actual operation of the machine tool, the base 1 is generally subjected to uneven external forces, i.e., shear stress at different positions, in the working state. Its structure itself has low contact stiffness and is prone to large-amplitude vibration, which affects the machining accuracy and makes it difficult to play the role of vibration isolation. At this time, the deformation component 431 drives the pressure plate component 42 to float through its own deformation, dissipating the reaction force transmitted from the pressure plate component 42 and keeping the other end of the pressure plate component 42 in contact with the machine tool leveling foot 10, thereby eliminating the vibration generated by the machine tool and reducing the impact of machine tool vibration on machining accuracy.

[0079] The spring-type anti-vibration absorption component 43 used in this embodiment is more suitable for low-frequency vibration conditions and can effectively and quickly dissipate the anti-vibration transmitted by the machine tool.

[0080] Example 3

[0081] like Fig. 3 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows:

[0082] In this embodiment, the deformation component 431 includes:

[0083] Piston tube 431b mounted on base 1; and

[0084] The pressure-resistant airbag 434b is adapted to be disposed inside the piston tube 431b, and its top is provided with an opening and communicates with the outside through a channel 4341 opened on the upper positioning member 434.

[0085] The upper positioning member 434 is slidably disposed inside the piston tube 431b.

[0086] When it is necessary to fill the pressure-resistant airbag 434b with a medium, the medium is filled into the pressure-resistant airbag 434b through the channel 4341 on the upper positioning member 434, causing the pressure-resistant airbag 434b to expand and provide support / buffering for the upper positioning member 434; the filling medium can be selected as a gaseous medium or a liquid medium according to the actual required pressure.

[0087] Preferably, the piston pipe 431b is also provided with an upper gasket 435b and a lower gasket 436b for protecting the pressure-resistant air bag 434b, preventing the pressure-resistant air bag 434b from being engaged with the upper positioning member 434 after expansion; the opposite side of the upper gasket 435b and the lower gasket 436b is arc-shaped; the upper gasket 435b is engaged with the upper positioning member 434, and the lower gasket 436b is engaged with the inner wall bottom of the piston pipe 431b.

[0088] Preferably, the top of the piston pipe 431b is provided with an upper cover 437b for vertically positioning the upper positioning member 434, and the rod part of the upper positioning member 434 passes through the upper cover 437b; the upper cover 437b can prevent the upper positioning member 434 from being separated from the piston pipe 431b.

[0089] Preferably, the channel 4341 is also provided with a hydraulic one-way valve 438b for filling the pressure-resistant air bag 434b with medium, preventing the medium from diffusing outward under pressure.

[0090] Preferably, the outer side of the piston pipe 431b is also provided with a protective cover 439b for preventing dust from entering the interior of the reverse vibration absorption assembly 43 and affecting normal work.

[0091] It should be noted that when it is necessary to pre-tighten the gasket vibration absorption assembly 3 to make the gasket vibration absorption assembly 3 completely adhere, the pressure-resistant air bag 434b is filled with medium, the pressure-resistant air bag 434b lifts the upper positioning member 434, and the pressure plate 422 extrudes the gasket vibration absorption assembly 3, so that the first vibration absorption gasket 31 and the second vibration absorption gasket 32 completely adhere without gap, reducing the instability of the machine tool during work due to the existence of the gap.

[0092] At the same time, during the actual work of the machine tool, the base 1 will be subjected to uneven external force, i.e. different positions of shear stress in the working state, the structure itself has low contact stiffness, and large amplitude vibration is easy to occur, thereby affecting the machining accuracy and making it difficult to play a role in vibration isolation. At this time, the pressure-resistant air bag 434b itself deforms to drive the pressure plate assembly 42 to float to dissipate the reverse vibration force conducted by the pressure plate assembly 42, and the other end of the pressure plate assembly 42 is in abutment with the machine tool foot 10, thereby eliminating the vibration of the machine tool and reducing the influence of the machine tool vibration on the machining accuracy.

[0093] The piston type reverse vibration absorption assembly 43 used in the embodiment is more suitable for the working condition of medium and high frequency vibration, and can quickly dissipate the reverse vibration transmitted during the work of the machine tool.

[0102] In step five, the elastic piece 431a is compressed to a corresponding length by the adjusting piece 432, so that the pressing force of the machine tool foot 10 reaches the design state.

[0103] After the step five is finished, the adjusting member 432 is adjusted to make the elastic member 431a return to the normal working state, and the pressing plate 422 is in the horizontal state.
