Description

Technical Field

[0001] This utility model relates to the field of machine tool foot technology, specifically to a high load-bearing machine tool foot structure. Background Technology

[0002] Machine tool feet are support components used to support machine tools, allowing them to be placed horizontally on the foundation. Therefore, feet used on high-precision machine tools, such as cutting machines and drilling machines, need to have a certain level of leveling capability.

[0003] In existing technologies, ball joints are often used to achieve this effect. However, for large machine tools, the support of the ball joint needs to have a large load-bearing capacity, which makes its diameter and volume larger than the commonly used size. Moreover, the ball joint structure is solid, which requires more material. As the size increases, the overall weight also increases, making it inconvenient to transport and install.

[0004] Currently, a type of foot that can also be horizontally adjusted without a ball joint has emerged. For example, the utility model patent with announcement number CN207421653U discloses an adaptive machine tool foot. This patent allows the first washer to move left and right on the nut by engaging the convex surface of the first washer with the concave surface of the nut. This achieves the horizontal adjustment effect of the ball joint in the traditional foot structure, making it easier for operators to use.

[0005] In the above technical solution, by utilizing the movable fit between the concave and convex surfaces, it is possible to adapt to horizontal offset during vertical adjustment without using the traditional ball joint method, resulting in a high degree of overall lightweighting. Although the concave surface on the top of the nut allows it to fit with the convex surface, it leads to a significant thinning of the nut's edge wall. When the machine tool's levelness needs to be compensated by the feet, the first washer is in an inclined working state, and its stress point will be more applied to the outer side of the nut. This eccentric load can easily cause plastic deformation at the edge of the nut, affecting the actual service life of the feet. To address these issues, this application provides a high-load-bearing machine tool feet structure. Utility Model Content

[0006] Based on the above description, this utility model provides a high load-bearing machine tool foot structure to solve the problem that although the existing machine tool foot structure meets the requirements of lightweighting, it is prone to reduced service life due to plastic deformation.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A high load-bearing machine tool foot structure includes a fixed base and a locking part. The fixed base is provided with an adjusting stud. An internal threaded cylinder is threadedly connected to the outer side of the adjusting stud. The inside of the adjusting stud can be threadedly connected to the locking part.

[0008] It also includes a support part and an abutment part. The support part is located at the top of the internal threaded cylinder. The support part is provided with a receiving part for the abutment part to be placed and rotated. The top and bottom of the receiving part are both open. The wall thickness of the support part is greater than 8mm.

[0009] The top of the abutment part has a through opening for the locking part to pass through.

[0010] The above technical solution allows the locking part to pass through the interior of the receiving part and the through-hole before connecting with the internal thread of the adjusting stud; the abutting part can rotate at multiple angles under the support of the receiving part, so that the abutting part can meet the adjustment requirements in the horizontal direction; at the same time, the bearing part can have a large bearing capacity and its edges are not easily deformed.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the supporting part includes a shim cylinder fixed to the top of the internal thread cylinder, a support block fixed to the top of the shim cylinder, and a number of ribs provided between the outer side of the shim cylinder and the bottom of the support block.

[0013] The outer side of the internally threaded cylinder is hexagonal.

[0014] Through the above technical solution, by combining the raised cylinder and the support block, and by using the rib plate for auxiliary support, the entire load-bearing part can have excellent load-bearing capacity.

[0015] Furthermore, the receiving portion includes an adjustment groove and a connecting hole formed on the top of the support block, the connecting hole being connected to the interior of the adjustment groove;

[0016] The inner side of the adjustment groove is arc-shaped, the connection between the adjustment groove and the connecting hole is arc-shaped, and the distance between the top opening of the adjustment groove and the outer side of the support block is L, 8mm. <L<15mm。

[0017] The above technical solution enables the adjustment groove and the connecting hole to form a space that can accommodate the abutment part and has a smooth edge transition; by limiting the wall thickness, it can meet the requirements of high load-bearing capacity.

[0018] Furthermore, the top and bottom of the internally threaded cylinder are both open, and the interior of the connecting hole is connected to the interior of the internally threaded cylinder, with the inner diameter of the connecting hole being equal to the inner diameter of the internally threaded cylinder.

[0019] The above technical solution enables the connecting hole to be combined with the internally threaded cylinder to form a channel.

[0020] Furthermore, the abutting part includes a rotating block placed in the adjusting groove and an abutting plate fixed to the top of the rotating block;

[0021] The rotating block is arc-shaped and can rotate around the center of the adjustment groove. The outer side of the rotating block is in contact with the inner side of the adjustment groove.

[0022] The above technical solution allows the rotating block to rotate inside the adjustment groove.

[0023] Furthermore, a lightweight groove and a through opening are provided between the top of the rotating block and the abutting plate. The lightweight groove is annular, and the through opening is located at the center of the rotating block and the abutting plate, with both the top and bottom being open.

[0024] The inner diameter of the through opening is equal to the inner diameter of the connecting hole.

[0025] Through the above technical solutions, the lightweight groove can reduce the material used for the rotating block and the abutment plate; the through-hole allows the locking part to pass through normally.

[0026] Furthermore, the lightweight groove is provided with a number of reinforcing ribs, which are distributed on the outside of the through opening and arranged at equal intervals.

[0027] The above technical solutions can improve the deformation resistance of lightweight tanks.

[0028] Furthermore, the locking part includes a hexagonal screw, and a spring washer and a wear-resistant washer are sleeved on the outside of the hexagonal screw;

[0029] The hexagonal screw moves between the through-hole and the connecting hole, and the wear-resistant washer is located on the side close to the adjusting stud.

[0030] The above technical solution can increase the tightness after locking by using spring washers and wear-resistant washers.

[0031] Furthermore, the top of the adjusting stud is provided with an internal thread groove for threaded connection of the hexagonal screw.

[0032] The above technical solution enables the locking function through the cooperation of the hexagonal screw and the internal thread groove.

[0033] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0034] 1. By setting up the load-bearing part, the wall thickness of the stress point can be greatly increased, making it less prone to plastic deformation, thus meeting the long-term use requirements of large machine tools; under the action of the abutment part, the contact area with the machine tool can be increased, thereby improving the stability of the connection.

[0035] 2. By creating a lightweight groove inside the abutment part, the overall material usage can be reduced, improving the overall lightweight structure. The lightweight groove is supported by the added reinforcing ribs, making it less prone to deformation. At the same time, the modular structure allows for easy disassembly and installation, and facilitates targeted inspection or replacement when a part of the structure is damaged, making it convenient for relevant personnel to operate.
