Description

Technical Field

[0001] The present invention relates to the technical field of machine tools, and more particularly, to a machine tool floor bolt, a machine tool, and a method for machining a machine tool floor bolt. Background Art

[0002] At present, in the field of traditional machine tool installation, as a key component to ensure the stability of the machine tool, the configuration method of the floor bolt has been restricted by the ground conditions. The common floor bolt installation methods are as follows:

[0003] The first one: directly place and fasten with bolts

[0004] For the method of directly placing and fastening bolts, although the operation is simple and fast, it lacks sufficient stability. Especially in a soft foundation or a factory environment with large vibrations, the machine tool is prone to shaking and small displacements, thus affecting the machining accuracy. In addition, this method usually cannot effectively reduce the vibration generated during the operation of the machine tool, further reducing the machining quality and efficiency.

[0005] The second one: grouting and fixing after excavating the foundation.

[0006] Although the floor bolt configuration method of grouting and fixing after excavating the foundation can significantly improve the stability and shock absorption effect of the machine tool, in actual application scenarios, it is often restricted by the ground thickness, bearing capacity, and environmental factors. For example, when the workshop floor is a reinforced concrete structure with insufficient thickness, or there is a complex pipeline layout underground and large-scale excavation operations cannot be carried out, this method is difficult to implement. Moreover, even if the ground allows excavation, the secondary grouting process is relatively cumbersome, increasing the installation cost and time consumption. Summary of the Invention

[0013] Further, the third connecting component includes: a second connecting structure, the second connecting structure includes an external thread segment and a supporting portion that are connected to each other, the supporting portion is located below the external thread segment to abut against a preset surface; wherein the external thread segment is passed through the crimping structure and is threadedly connected to the crimping structure; a third nut, the third nut is sleeved on the external thread segment and is threadedly connected to the external thread segment; wherein the third nut is located below the crimping structure to support the crimping structure; there is one third nut; or, there are multiple third nuts, and the multiple third nuts are spaced apart along the extension direction of the external thread segment.

[0014] Furthermore, the crimping structure has a through hole, and the chemical bolt is inserted into the through hole; the through hole is a strip-shaped hole or a waist-shaped hole, and at least part of the positive projection of the second nut on the through hole is located on the crimping structure.

[0015] Furthermore, the first end of the crimping structure has an opening, the opening avoids the first nut, and the second end of the crimping structure has an internal threaded hole, at least part of the external thread section is inserted into the internal threaded hole and threadedly connected to the internal threaded hole; the opening, the internal threaded hole and the through hole are symmetrically arranged about the center plane S of the crimping structure.

[0016] According to another aspect of the present invention, a machine tool is provided, comprising a machine tool body and a machine tool foot connected to the machine tool body; wherein the machine tool foot is the above-mentioned machine tool foot.

[0034] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0036] In the present invention, unless otherwise stated, the orientation terms such as "upper, lower" are generally in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left, right" are generally left and right as shown in the drawings; "inside, outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms do not limit the present invention.

[0037] In order to solve the problem that the installation method of the machine tool foundation in the prior art is difficult to meet the user's usage requirements, the present application provides a machine tool foundation, a machine tool and a method for machining a machine tool foundation.

[0038] Such as Figures 1 to 5As shown in the figure, the machine tool foundation feet include a first connection assembly 10, foundation pads 30, a second connection assembly 40, and a crimping structure 50. The first connection assembly 10 includes a first connection structure 11, and the first connection structure 11 is threadedly connected to the machine tool body 20. The foundation pads 30 are located below the machine tool body 20, and the foundation pads 30 are connected to the first connection structure 11. The second connection assembly 40 includes chemical bolts 41, and at least a part of the chemical bolts 41 is tightened on a preset surface. The crimping structure 50 has a crimping surface disposed opposite to at least a part of the machine tool body 20, so as to press the machine tool body 20 toward the preset surface through the crimping surface. Wherein, at least a part of the second connection assembly 40 is in limit stop with the crimping structure 50 to prevent the crimping structure 50 from moving toward the side away from the preset surface; or, the second connection assembly 40 is connected to the crimping structure 50.

[0039] Applying the technical solution of this embodiment, the second connection assembly 40 is firmly fixed on the preset surface through the chemical bolts 41. Combining with the pressing action of the crimping structure 50 on the machine tool body 20, the vibration of the machine tool during the processing is effectively prevented, thereby improving the processing accuracy and overall stability, and further solving the problem that the installation method of the machine tool foundation feet in the prior art is difficult to meet the user's usage requirements. At the same time, the above installation method of the machine tool foundation feet does not require excavation of the foundation, and can be used in environments with limited ground bearing capacity or where large-scale construction is not allowed, greatly expanding the installation range of the machine tool and reducing the installation cost and time.

[0040] Compared with the method of excavating the foundation to re-do the foundation in the prior art, the machine tool foundation feet in this embodiment adopt the installation method of chemical bolts supplemented by the crimping structure 50 to fix and support the machine tool body 20, which neither requires a too deep depth nor requires large-scale re-laying of the foundation, and can achieve the technical effect of relative shock absorption and stability.

[0041] In this embodiment, the method of using chemical bolts 41 in cooperation with foundation pads 30 and a crimping structure 50 simplifies the complex processes of traditional foundation foot installation, such as digging the ground, grouting and other steps, making the installation process simpler and faster, and at the same time reducing the errors caused by improper operation.

[0042] In this embodiment, the crimping structure 50 is a pressing plate, so that the structure of the crimping structure 50 is simpler, easier to process and implement, and reduces the processing cost and processing difficulty of the machine tool foundation feet.

[0043] Optionally, the first connection structure 11 is a screw rod. One end of the screw rod passes through the machine tool body 20 and is threadedly connected to the floor anchor 30; alternatively, one end of the screw rod passes through the machine tool body 20 and is welded or riveted to the floor anchor 30. In this way, through threaded connection, welding or riveting, a firm mechanical connection is formed between the first connection structure 11 (i.e., the screw rod) and the floor anchor 30, providing high-strength support for the machine tool body 20 and ensuring the stability of the machine tool body 20 under various working conditions. When choosing threaded connection, the connection between the screw rod and the floor anchor 30 can be finely adjusted, facilitating the adjustment of the level of the machine tool during installation to adapt to different ground conditions. Welding or riveting provides permanent fixation and is suitable for occasions where frequent adjustment is not required, ensuring long-term structural stability.

[0044] In this embodiment, the first connection structure 11 is a screw rod. One end of the screw rod passes through the machine tool body 20 and is threadedly connected to the floor anchor 30. In this way, the threaded connection method allows for easy disassembly and replacement of the floor anchor 30 or the screw rod during subsequent maintenance work, thereby improving the operation flexibility of the staff.

[0045] As Figure 4 shown, the first connection assembly 10 further includes a first nut 12. The first nut 12 is sleeved on the screw rod and is threadedly connected to the screw rod. Among them, the first nut 12 is pressed against the surface of the machine tool body 20 away from the preset surface; the first nut 12 is one; or, the first nut 12 is multiple, and multiple first nuts 12 are arranged at intervals along the extension direction of the screw rod. In this way, the first nut 12 is sleeved on the screw rod and is threadedly connected to the screw rod, which can effectively lock the connection between the screw rod and the machine tool body 20, preventing the screw rod from loosening due to machine tool vibration or uneven ground, thereby improving the stability and machining accuracy of the machine tool. At the same time, the setting of the first nut 12 allows for fine adjustment during installation and maintenance to ensure the appropriate distance and level between the machine tool body 20 and the preset surface (ground); when multiple first nuts 12 are arranged at intervals along the extension direction of the screw rod, not only does it increase the number of locking points, improve the reliability of the connection, but also it can further prevent the screw rod from displacing when subjected to lateral force, enhancing the vibration resistance and stability of the first connection assembly 10.

[0046] In this embodiment, the first nut 12 is one, thereby reducing the number of components of the first connection assembly 10 and reducing the operation difficulty of the staff. At the same time, the above setting also reduces the processing cost of the first connection assembly 10.

[0047] In other embodiments not shown in the drawings, the first nut 12 is two, or three, or four, or five, or multiple.

[0048] As Figure 4As shown, the second connection assembly 40 also includes a second nut 42, which is sleeved on the chemical bolt 41 and threadedly connected to the chemical bolt 41. The second nut 42 is crimped to the surface of the crimping structure 50 that is away from the crimping surface; there is one second nut 42; or there are multiple second nuts 42, and the multiple second nuts 42 are spaced along the extension direction of the chemical bolt 41. In this way, the second nut 42 is fixed to the chemical bolt 41 through a threaded connection and crimped to the crimping structure 50. This crimping and locking mechanism ensures the close connection between the chemical bolt 41 and the crimping structure 50, and enhances the strength and rigidity of the connection. At the same time, the setting of a single or multiple second nuts 42 allows the staff to adjust the position of the crimping structure 50 as needed, ensuring an ideal clamping state between the machine tool body 20 and the preset surface, which helps to improve the levelness and processing accuracy of the machine tool; when multiple second nuts 42 are used and arranged at intervals along the direction of the chemical bolt 41, multiple locking points can be formed between the chemical bolt 41 and the crimping structure 50 to disperse the load and reduce the stress concentration of a single nut, thereby improving the fatigue resistance of the entire system and extending its service life.

[0049] In this embodiment, there is only one second nut 42, thereby reducing the number of parts of the second connecting assembly 40 and reducing the difficulty of operation for the staff. At the same time, the above arrangement also reduces the processing cost of the second connecting assembly 40.

[0050] In other embodiments not shown in the drawings, the number of the second nuts 42 is two, three, four, five, or more.

[0051] like Figure 3 and Figure 4 As shown, the first end of the crimping structure 50 is crimped to the machine tool body 20, and the machine tool foot also includes a third connecting component 60. Among them, a part of the third connecting component 60 is connected to the second end of the crimping structure 50, and another part of the third connecting component 60 is abutted against the preset surface to support the crimping structure 50. In this way, the third connecting component 60 is connected to the second end of the crimping structure 50 and abuts against the preset surface, thereby forming a stable support frame, effectively preventing the crimping structure 50 from being displaced when subjected to lateral or longitudinal forces, and enhancing the overall stability of the machine tool. At the same time, the crimping structure 50 presses the machine tool body 20, and the third connecting component 60 supports the crimping structure 50, so that the force can be more evenly transmitted from the machine tool body 20 to the preset surface, reducing local stress concentration, avoiding potential damage to the machine tool, and improving the reliability of long-term use.

[0052] Specifically, through the support of the third connecting assembly 60, the crimping structure 50 can better resist vibration and impact, ensuring that the machine tool remains stable during the processing, thereby improving the processing accuracy and product quality.

[0053] As Figure 2 and Figure 4 shown, the third connection component 60 includes a second connection structure 61. The second connection structure 61 includes an external thread section 611 and a support portion 612 that are connected to each other. The support portion 612 is located below the external thread section 611 to abut against a preset surface. Among them, the external thread section 611 is passed through the crimping structure 50 and is threadedly connected to the crimping structure 50. In this way, the support portion 612 directly abuts against the preset surface, thereby providing a stable bottom support for the crimping structure 50, and the threaded connection between the external thread section 611 and the crimping structure 50 ensures their stable connection, thereby significantly improving the support effect of the third connection component 60 on the crimping structure 50, thus enhancing the structural stability and vibration resistance of the entire machine tool foot. At the same time, the threaded connection between the external thread section 611 and the crimping structure 50 allows the position of the crimping structure 50 to be finely adjusted by adjusting the tightening degree of the thread, thereby precisely controlling the distance and levelness between the machine tool body 20 and the preset surface, ensuring the best working state of the machine tool.

[0054] In this embodiment, the support portion 612 is in a plate shape, and the external thread section 611 and the support portion 612 are arranged perpendicular to each other.

[0055] As Figure 4 shown, the third connection component 60 further includes a third nut 62. The third nut 62 is sleeved on the external thread section 611 and is threadedly connected to the external thread section 611. Among them, the third nut 62 is located below the crimping structure 50 to support the crimping structure 50; the third nut 62 is one; or, the third nut 62 is multiple, and multiple third nuts 62 are arranged at intervals along the extension direction of the external thread section 611. In this way, the third nut 62 is threadedly connected to the external thread section 611 as a fastener, and the third nut 62 is located below the crimping structure 50, which can effectively support and lock the crimping structure 50 to ensure that it will not be displaced when subjected to external forces, improving the stability of the entire machine tool foot. At the same time, by adjusting the tightening degree of the third nut 62, the distance between the crimping structure 50 and the preset surface can be finely adjusted to achieve precise levelness adjustment of the machine tool body 20; when multiple third nuts 62 are arranged at intervals along the extension direction of the external thread section 611, multiple locking effects can be provided, and even in long-term use or a vibrating environment, the loosening of the threaded connection can be effectively prevented.

[0056] In this embodiment, the third nut 62 is one, thereby reducing the number of components of the third connection component 60 and reducing the operation difficulty of the staff. At the same time, the above setting also reduces the processing cost of the third connection component 60.

[0057] In other embodiments not shown in the drawings, the third nut 62 is two, or three, or four, or five, or multiple.

[0058] like Figure 5 As shown, the crimping structure 50 has a through hole 51, and the chemical bolt 41 is inserted into the through hole 51; the through hole 51 is a strip hole or a waist hole, and at least part of the orthographic projection of the second nut 42 on the through hole 51 is located on the crimping structure 50. In this way, the through hole 51 is designed as a strip hole or a waist hole, which can provide a larger adjustment range. The above hole shape can adapt to the slight unevenness of the preset surface (ground), so that the crimping structure 50 can adjust the position within a certain range, thereby ensuring the stability and levelness of the machine tool, and achieving good fixation even in an environment where the ground conditions are not very ideal. At the same time, by making at least part of the orthographic projection of the second nut 42 on the through hole 51 located on the crimping structure 50, it is prevented that the second nut 42 comes out of the through hole 51 and affects the locking effect of the second nut 42 on the chemical bolt 41.

[0059] like Figure 5 As shown, the first end of the crimping structure 50 has an opening 52, and the opening 52 avoids the first nut 12. The second end of the crimping structure 50 has an internal threaded hole, and at least part of the external thread section 611 is inserted into the internal threaded hole and threadedly connected to the internal threaded hole. In this way, the crimping structure 50 is threadedly connected to the external thread section 611 through the internal threaded hole at its second end. The above-mentioned threaded matching can significantly enhance the connection stability between the crimping structure 50 and the second connection structure 61, avoiding loosening caused by external vibration or improper operation, thereby improving the reliability of the overall structure. At the same time, the above-mentioned setting of the opening 52 allows the first nut 12 to pass directly without obstruction, reducing the position adjustment of the first nut 12 during assembly, making the assembly process smoother and faster. In addition, the above-mentioned setting of the opening 52 also facilitates the inspection and adjustment of the nut during subsequent maintenance.

[0060] In this embodiment, the opening 52, the internal threaded hole and the through hole 51 are symmetrically arranged about the center plane S of the crimping structure 50. In this way, the symmetrically arranged opening 52, the internal threaded hole and the through hole 51 can ensure that the crimping structure 50 has good balance when fixed and installed, so as to prevent any deviation or twisting during the installation process, thereby improving the stability of the overall system. At the same time, the symmetrical design on the center plane helps to evenly distribute the pressure and load, and reduce the vibration and noise caused by the unilateral force.

[0061] In this embodiment, the size of the screw is M42×1.5, the size of the first nut 12 is M42×1.5 (GB812-1988), the size of the chemical bolt 41 is M20×400, the size of the second nut 42 is M20, the size of the third nut 62 is M30×2 fine thread, and the size of the external thread section 611 is M30×2×200.

[0062] like Figures 1 to 3As shown in the figure, the present application also provides a machine tool, including a machine tool body 20 and a machine tool foot 70 connected to the machine tool body 20; wherein, the machine tool foot is the above-mentioned machine tool foot 70.

[0063] The present application also provides a machining method for a machine tool foot, which is applicable to the above-mentioned machine tool foot; the machining method for the machine tool foot includes:

[0064] Step S1: Thread-connect the first connection structure 11 of the machine tool foot with the machine tool body 20;

[0065] Step S2: Hoist the overall structure formed by the assembled machine tool body 20 and the first connection structure 11 to the position where the preset surface is located, and then assemble the first connection structure 11 and the anchor pad 30;

[0066] Step S3: Drill chemical bolt holes, insert chemical bolts 41 into the chemical bolt holes, and then inject anchoring agent;

[0067] Step S4: Lock the first connection structure 11, chemical bolts 41 and the second connection structure 61 of the machine tool foot.

[0068] Specifically, the second connection component is firmly fixed on the preset surface through chemical bolts. Combining with the pressing effect of the crimping structure on the machine tool body, it effectively prevents the vibration of the machine tool during the machining process, thereby improving the machining accuracy and overall stability, and further solving the problem that the installation method of the machine tool foot in the prior art is difficult to meet the user's usage requirements. At the same time, the above installation method of the machine tool foot does not require excavation of the foundation, and can be used in environments with limited ground bearing capacity or where large-scale construction is not allowed, greatly broadening the installation range of the machine tool and reducing the installation cost and time.

[0069] Compared with the method of excavating the foundation to re-do the foundation in the prior art, the machine tool foot in the present application uses the installation method of chemical bolts supplemented by a crimping structure to fix and support the machine tool body, which neither requires a deep depth nor requires large-scale re-laying of the foundation, and can achieve the technical effect of relative shock absorption and stability.

[0070] In this embodiment, the installation steps of the machine tool foot and the machine tool body are specifically as follows:

[0071] The first step: First, assemble and fix the screw rod and the machine tool body 20 according to the design requirements;

[0072] The second step: Use a crane to place the machine tool body 20 at the position planned according to the technical requirements. Next, adjust the anchor pad 30 to support the machine tool body 20 to ensure the level of the bed body position of the machine tool body 20 during fixation;

[0073] The third step: Determine the position of the chemical bolt holes through the screw rod holes:

[0074] Step 4: After determining the drilling positions of the chemical anchor bolt holes, move the tool magazine assembly away, and use a suitable drilling tool to drill chemical anchor bolt holes at the predetermined positions;

[0075] Step 5: Insert the chemical anchor bolt 41 into the chemical anchor bolt hole, and then inject an appropriate amount of anchoring agent to ensure that the chemical anchor bolt can be firmly fixed in the chemical anchor bolt hole; afterwards, wait for the anchoring agent to cure to reach the strength required by the design. After the chemical anchor bolt cures, refix the machine tool on the machine tool bed;

[0076] Step 6: Lock the screw rod, the chemical anchor bolt 41, and the second connection structure 61 to ensure the stability and reliability of the machine tool.

[0077] Optionally, the method for machining the machine tool feet further includes step S0 before step S1:

[0078] Step S01: Prepare chemical anchor bolts, anchoring agent, wrenches, screwdrivers, measuring tools (such as spirit levels, theodolites), cranes, and machine tool sole plates;

[0079] Step S02: Check whether the quality and specifications of materials such as chemical anchor bolts, nuts, and gaskets meet the requirements.

[0080] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0081] The second connection assembly is firmly fixed on the preset surface through chemical anchor bolts, combined with the pressing effect of the crimping structure on the machine tool body, effectively preventing the vibration of the machine tool during the machining process, thereby improving the machining accuracy and overall stability, and further solving the problem that the installation method of the machine tool feet in the prior art is difficult to meet the user's usage requirements. At the same time, the above installation method of the machine tool feet does not require excavation of the foundation, and can be suitable for use in environments with limited ground bearing capacity or where large-scale construction is not allowed, greatly expanding the installation range of the machine tool and reducing the installation cost and time.

[0082] Compared with the method of re-making the foundation by excavating the foundation in the prior art, the machine tool feet in the present application use the installation method of chemical anchor bolts supplemented by a crimping structure to fix and support the machine tool body, which neither requires too deep a depth nor large-scale re-laying of the foundation, and can achieve the technical effects of relative shock absorption and stability.
