This utility model discloses a machine tool bed vibration damping and deformation prevention anchor bolt structure, including a machine tool base, a floor, and a pre-embedded bolt body. The floor is provided below the machine tool base, and the pre-embedded bolt body is embedded in the floor. In this utility model, the top of the pre-embedded bolt body in the floor is connected to the machine tool base, and the pre-embedded bolt body is locked with a nut. During this process, an adjusting shim, a lower shim, and an upper shim are fitted onto the surface of the pre-embedded bolt body from bottom to top. The adjusting shim is in direct contact with the grout layer poured on the top surface of the floor. The V-shaped groove of the lower shim is connected to the V-shaped protrusion of the upper shim. Then, the lower shim in the adjusting shim is locked by tightening the bolt. The lower and upper shims are made of nitrile synthetic rubber, which can effectively dampen the vibration of the machine tool and reduce the external transmission of vibration force. The surrounding adjusting shim and the reinforcing block welded to its outside can provide effective support for the pre-embedded bolt body.

Description

Technical Field

[0001] This utility model relates to the field of machine tool support structure technology, and in particular to a machine tool bed shock-absorbing and deformation-preventing anchor bolt structure. Background Technology

[0002] Most existing types of commonly used machine tool feet can only serve as leveling feet, and they are not shock-resistant or loosening-proof. Their support stability is also unstable due to the ground environment, which greatly reduces the performance of the machine tool.

[0003] Loosening of the machine tool's support feet is caused by vibrations during machining, especially during prolonged heavy cutting (heavy cutting refers to vibrations generated when the tool contacts the workpiece with an excessively large contact area). This sustained vibration can cause the support rods or surfaces of the machine tool's support feet to loosen, affecting the machining accuracy, surface finish, and even the machine's lifespan. Vibration in the support feet occurs because the support surfaces at the bottom of the machine tool and the support feet are in metal-to-metal contact. In such cases, if the underground environment is foam-like or the machine tool is installed on a floor, ground vibrations are likely to occur, affecting the overall vibration of the machine tool and thus impacting the surface finish of the machining process. This contributes to instability in the machining accuracy of the machine tool in its later use.

[0004] To address this issue, a shock-absorbing and deformation-resistant anchor bolt structure for machine tool beds is proposed, which possesses the advantages of shock absorption and deformation prevention, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a shock-absorbing and deformation-resistant anchor bolt structure for machine tool beds.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a machine tool bed vibration damping and deformation prevention anchor bolt structure, comprising a machine tool base, a floor, and a pre-embedded bolt body. A floor is provided below the machine tool base, and the pre-embedded bolt body is embedded within the floor. The upper part of the pre-embedded bolt body extends to the top surface of the floor, and a nut is threaded through the machine tool base at the top of the pre-embedded bolt body. A grouting layer is poured on the top surface of the floor corresponding to the installation position of the pre-embedded bolt body, and a grouting layer is provided on the top surface of the grouting layer. An adjusting shim is provided, which is fitted with a pre-embedded bolt. A lower shim is movably installed on the inner side of the adjusting shim, and an upper shim is provided above the lower shim, which is fitted with the pre-embedded bolt. The upper shim is bonded to the bottom surface of the machine tool base, and the bottom surface of the upper shim is integrally provided with several V-shaped protrusions. The top surface of the lower shim is provided with several V-shaped grooves corresponding to the V-shaped protrusions. A reinforcing block is welded to the outer surface of the adjusting shim, and a tightening bolt connected to the lower shim is inserted through the side wall of the adjusting shim.

[0007] As a further description of the above technical solution: a steel frame is installed around the grouting layer, and the steel frame is fitted around the pre-embedded bolt.

[0008] As a further description of the above technical solution: the surfaces of the upper pad and the lower pad are provided with several through holes corresponding to the pre-embedded bolts, and the facing surfaces of the upper pad and the lower pad are provided with sloping surfaces.

[0009] As a further description of the above technical solution: the top surface of the lower pad is provided with a T-shaped groove, and the bolt head of the tightening bolt extends into the T-shaped groove.

[0010] As a further description of the above technical solution: the bottom end of the pre-embedded bolt is provided with a hook-shaped part, and the hook-shaped part of the pre-embedded bolt is buried in the ground.

[0011] As a further description of the above technical solution: the adjusting shim has an overall square box structure with an open top surface, and the side walls of the adjusting shim are provided with mounting holes corresponding to the tightening bolts, and each side of the adjusting shim is welded with a set of reinforcing blocks.

[0012] This utility model has the following beneficial effects: In this invention, the top of the pre-embedded bolt in the floor is connected to the machine tool base, and the pre-embedded bolt is locked with a nut. During this process, the adjusting shim, lower shim, and upper shim are fitted onto the surface of the pre-embedded bolt from bottom to top. The adjusting shim is in direct contact with the grout layer poured on the top surface of the floor. The V-shaped groove of the lower shim is connected to the V-shaped protrusion of the upper shim. Then, the lower shim inside the adjusting shim is locked by tightening the bolt. The lower and upper shims, made of nitrile synthetic rubber, can effectively attenuate the vibration of the machine tool and reduce the external transmission of vibration force. The surrounding adjusting shim and the reinforcing block welded to its outside can provide effective support for the pre-embedded bolt, avoiding the deformation of the pre-embedded bolt caused by the lateral force of the machine tool, thereby ensuring the processing dimensional accuracy and quality.

The lower pad 8 and the upper pad 7 are made of nitrile synthetic rubber, which can effectively attenuate the vibration of the machine tool and reduce the external transmission of vibration force. Through the adjusting pad 6 and the reinforcing block 10 welded to its outer side, effective support can be provided for the pre-embedded bolt 3, avoiding the deformation of the pre-embedded bolt 3 caused by the lateral force of the machine tool. In one embodiment, a steel frame is installed around the grouting layer 5, and the steel frame is fitted around the pre-embedded bolt 3. The grouting layer 5 with the steel frame meets the grouting requirements of the grouting layer 5, enhances the installation reliability of the pre-embedded bolt 3, and provides support for the adjusting shim 6.

[0018] In one embodiment, the surfaces of the upper pad 7 and the lower pad 8 are provided with a plurality of through holes 14 corresponding to the pre-embedded bolt 3, and the facing surfaces of the upper pad 7 and the lower pad 8 are provided with sloping surfaces.
