Abstract
Description
Technical Field
[0001] The utility model relates to the field of machine tool installation and debugging, in particular to a machine tool bed position regulating device. Background Art
[0002] The bed is the foundation of a machine tool, supporting and mounting other components and serving as the benchmark for machining. Due to the significant weight and volume of the bed frames of large, heavy, and ultra-heavy machine tools, installation and commissioning are also more challenging. The installation and commissioning of heavy-duty machine tool assemblies made of multiple sections is complex and challenging. Therefore, the installation and commissioning of bed guideways is crucial to the performance and accuracy of machine tools, especially those with multiple sections.
[0003] During the installation and commissioning phase of a machine tool, the bed requires preliminary leveling before the foundation grouting. Currently, two methods are commonly used in the domestic machine tool industry. One uses standard adjustment shims for pre-leveling, while the other utilizes a simple leveling device that adjusts the bed height by rotating bolts. Both methods support the bed at four points, adjusting the height of the device to achieve horizontal coplanarity of the bed rails. Aligning multiple sections of the bed rails requires repeated lifting of the bed for adjustment.
[0004] The use of adjustment shims for bed leveling has several drawbacks: Because the machine tool foundation is difficult to achieve a completely level surface, the adjustment range of the adjustment shims is limited, and multiple adjustment shims are often required to level the bed rails. This problem is particularly pronounced when adjusting the coplanarity of the bed rails on multiple sections of the bed. The large number of adjustment shims can lead to poor contact between them, resulting in an insecure bed support point. Furthermore, adding adjustment shims requires hoisting the bed before performing the operation, which is not only time-consuming and labor-intensive, but can also damage the bed.
[0005] Simple leveling devices also have disadvantages: the adjustment bolt needs to be rotated during adjustment, and the device may rotate due to the force, thereby affecting the adjustment accuracy. Utility Model Content
[0006] The purpose of the present invention is to provide a machine tool bed adjustment device to solve the problems raised in the above-mentioned background technology, so as to realize the rapid and effective adjustment of the horizontality and alignment of the machine tool bed guide rails. The whole process is time-saving and labor-saving, and there is no need to use gaskets or lift the machine tool bed.
[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a machine tool bed position adjustment device, comprising a base, an adjusting bolt, a side top bolt and a steel ball; the base comprises a longitudinal plate and a transverse plate; the adjusting bolt is installed on the transverse plate, and the side top bolt is installed on the longitudinal plate; a circular hole groove is provided on the upper part of the adjusting bolt, the lower part of the steel ball is provided in the circular hole groove, and the upper part of the steel ball protrudes from the upper part of the circular hole groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are: the application of the adjustment device makes the leveling operation of the machine tool bed convenient, quick, labor-saving, and improves the work efficiency.
[0014] The horizontality of the machine tool bed guide rails is adjusted by adjusting bolts, and the alignment of the machine tool bed guide rails is adjusted by side top bolts. The adjustment process is time-saving and labor-saving. No gaskets are needed, and the machine tool bed does not need to be lifted.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] refer to Figure 1-4 As shown, the utility model discloses a machine tool bed position adjustment device, which includes a base 1, an adjustment bolt 2, a side top bolt 3 and a steel ball 4.
[0023] Specifically, the base 1 is an integrated design consisting of a longitudinal plate 11 and a transverse plate 12. The bottom surface of the transverse plate 12 is a square structure, which effectively prevents the device from rotating due to torque during use. The longitudinal plate 11 is threaded with horizontally arranged side top bolts 3, while the transverse plate 12 is threaded with vertically arranged adjustment bolts 2. When the device is in use, the longitudinal plate 11 is located on the outside. When adjusting the height of the adjustment bolt 2, a wrench is required to turn the bolt to move it up and down. To facilitate operation and leave room for operation, the longitudinal plate 11 is a vertical plate with grooves on the side, which greatly facilitates operation.
[0024] Adjust the bolt 2. The bolt head of the adjusting bolt 2 is provided with a circular hole groove. Most of the steel ball 4 can be placed in the circular hole groove, and the upper small part is located above the upper surface of the bolt head of the adjusting bolt 2. When in use, the adjusting device needs to be carried, so the spherical body of the steel ball 4 is embedded in the circular hole groove of the adjusting bolt 2 so that the center of the spherical body of the steel ball 4 is lower than the upper surface of the adjusting bolt 2. Then, the sphere is clamped into the circular hole groove by tightening the circular hole groove, which makes the device convenient and safe during use and transportation.
[0025] After the horizontality of the bed is adjusted, the alignment of the guide rails of each section of the bed can be adjusted. By rotating the side top bolts 3, the free ends of the side top bolts 3 are used to press the bed, so that each section of the bed moves horizontally until the guide rails of each section of the bed meet the alignment requirements.
[0026] When in use, the steel ball 4 supports the machine bed, forming point contact. This reduces friction and the required torque when rotating the adjustment bolt 2. Lubricating the steel ball 4 can further reduce friction, making operation more convenient and labor-saving. Furthermore, the steel ball 4 is placed between the machine bed and the adjustment bolt 2 and positioned by the circular groove, forming contact with the circular groove, resulting in high positioning accuracy.
[0027] In summary, in actual application, the horizontal plate 12 of the adjustment device is in contact with the ground and is distributed on both sides of the length direction of the machine tool bed. The machine tool bed is placed on the adjustment device and supported by the steel ball 4. The free end of the side top bolt 3 and the steel ball 4 are respectively opposite to the side and bottom of the ground edge of the machine tool bed. When it is necessary to adjust the level of the machine tool bed, it is only necessary to rotate the adjustment bolt 2 to change the vertical position of the steel ball 4, thereby achieving precise adjustment of the level of the machine tool bed. Since the adjustment range of the adjustment bolt 2 is large, it is sufficient to meet various adjustment needs, and there is no need to use gaskets or lift the machine tool bed. For a combined bed composed of multiple bed sections, multiple adjustment devices need to be installed at the bottom of each bed section. After the bed level is adjusted, the alignment adjustment of the guide rails of each bed section can be carried out. By rotating the side top bolt 3, the free end of the bed is used to press the bed, so that each bed section moves in the horizontal direction until the guide rails of each bed section meet the alignment requirements.
[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
