Description

Technical Field

[0001] This utility model relates to the field of mineral casting bed technology, specifically a fatigue-resistant mineral casting bed with stress relief grooves. Background Technology

[0002] As the core load-bearing component of a machine tool, the bed is a typical metal casting product, mainly made of gray cast iron or mineral composite materials.

[0003] However, during the production and use of existing mineral casting beds, internal stress accumulation is caused by differences in resin curing shrinkage, uneven aggregate distribution, and temperature gradients. At the same time, long-term exposure to machine tool cutting vibration and periodic loads can lead to the initiation of microcracks in stress concentration areas, resulting in reduced service life. Utility Model Content

[0004] The purpose of this invention is to provide a fatigue-resistant mineral casting bed with stress relief grooves to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fatigue-resistant mineral casting bed with stress relief grooves, comprising a bed body and a stress relief assembly. Guide rail mounting seats are provided at the top of both ends of the bed body. The stress relief assembly is located in the middle of the top surface of the bed body and includes a first groove, a second groove and a silicone strip. The first groove is formed in the top surface of the middle part of the bed body, and the second groove is connected to the middle of the first groove. Silicone strips are provided inside both the first groove and the second groove.

[0006] Furthermore, the first groove has a U-shaped cross-section, and the first grooves are equidistantly distributed about the top surface of the bed body.

[0007] Furthermore, the second groove is perpendicular to the first groove, and the second groove is equidistant from the top surface of the bed body.

[0008] Furthermore, the top surface of the silicone strip is flush with the top surface of the middle part of the bed body, and the silicone strip is mesh-like.

[0009] Furthermore, the top surface of the guide rail mounting base is provided with a mounting groove, and the bottom of the mounting groove is provided with a barrier groove.

[0010] Furthermore, the guide rail mounting base is provided with a connecting component inside, and the connecting component includes an adjustment hole and a buffer pad. The guide rail mounting base is provided with an adjustment hole inside, and a buffer pad is fixed on the top of the guide rail mounting base.

[0011] Furthermore, the connecting assembly also includes a groove and a slider. The bottom of the guide rail mounting base is provided with a groove, and a slider is slidably connected inside the groove.

[0012] Furthermore, the connecting assembly also includes a threaded hole and a rubber pad. The slider has a threaded hole inside and a rubber pad is provided on the top of the slider.

[0013] This utility model provides a fatigue-resistant mineral casting bed with stress relief grooves, which has the following beneficial effects: 1. This utility model, through the setting of stress relief components, uses the arrayed first and second grooves to attract and release local concentrated stress during use, making it a natural crack arrest zone, forcing the crack to turn or terminate at the groove, while breaking the continuous structure, eliminating the rigid constraint of the geometric change zone, promoting uniform stress distribution, and improving the overall fatigue resistance. At the same time, silicone strips are used to fill the depressions, which not only keeps the bed surface flat and prevents debris intrusion, but also provides additional damping and vibration reduction to absorb vibration energy. 2. Through the design of the connecting components, this utility model allows for initial positioning of the guide rail during installation. Simply place the guide rail in the mounting groove and ensure it aligns with its side wall. The longer adjustment hole allows for adjustment of the slider's position within the groove according to the mounting hole position on the guide rail, improving the overall adaptability. Tightening the bolts then moves the guide rail and slider towards the top surface of the guide rail mounting base. Simultaneously, a buffer pad and a rubber pad cushion the movement between the slider and the guide rail mounting base. Therefore, during subsequent use, when vibrations from the guide rail are transmitted to the machine bed via bolts, the buffer pad and rubber pad absorb some of the vibration, extending the overall service life. Furthermore, when the threaded hole is damaged, only the corresponding slider needs to be replaced, saving maintenance costs. Attached Figure Description

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figure 1 and Figure 2 As shown, a fatigue-resistant mineral casting bed with stress relief grooves includes a bed body 1 and a stress relief assembly 3. Guide rail mounting seats 2 are provided at the top of both ends of the bed body 1. The stress relief assembly 3 is located in the middle of the top surface of the bed body 1 and includes a first groove 301, a second groove 302, and a silicone strip 303. The first groove 301 is formed in the middle of the top surface of the bed body 1, and the second groove 302 is connected to the middle of the first groove 301. The cross-section of the first groove 301 is U-shaped, and the first grooves 301 are equidistantly distributed about the top surface of the bed body 1. The arrayed first grooves 301 and second grooves 302 attract and release localized concentrated stress, making it a natural stress. The crack arrestor zone forces the crack to turn or terminate at the groove, while breaking the continuous structure, eliminating the rigid constraints of the geometric change zone, promoting uniform stress distribution, and improving the overall fatigue resistance. The second groove 302 is perpendicular to the first groove 301, and the second groove 302 is equidistant from the top surface of the bed body 1, which can release stress in multiple directions. The first groove 301 and the second groove 302 are both provided with silicone strips 303. The top surface of the silicone strips 303 is flush with the middle top surface of the bed body 1, and the silicone strips 303 are mesh-like. The silicone strips 303 are used to fill the depressions, which not only keeps the bed surface flat and prevents debris intrusion, but also provides additional damping and vibration reduction to absorb vibration energy.

[0018] like Figure 1 and Figure 3As shown, the top surface of the guide rail mounting base 2 has a mounting groove 4, and the bottom of the mounting groove 4 has a blocking groove 5. Placing the guide rail in the mounting groove 4 and making it fit against its side wall can initially limit the guide rail's position. The blocking groove 5 can also release some stress. The guide rail mounting base 2 has a connecting component 6 inside, and the connecting component 6 includes an adjustment hole 601 and a buffer pad 602. The guide rail mounting base 2 has an adjustment hole 601 inside, and the top of the guide rail mounting base 2 is fixed with a buffer pad 602. The connecting component 6 also includes a sliding groove 603 and a slider 604. The bottom of the guide rail mounting base 2 has... The system includes a slide groove 603, with a slider 604 slidably connected inside the slide groove 603. Because the adjustment hole 601 is relatively long, the position of the slider 604 in the slide groove 603 can be adjusted according to the mounting hole position on the guide rail, thereby improving the overall adaptability. The connecting component 6 also includes a threaded hole 605 and a rubber pad 606. The slider 604 has a threaded hole 605 inside, and a rubber pad 606 is provided on the top of the slider 604. When the vibration on the guide rail is transmitted to the bed body 1 through the bolts, the buffer pad 602 and the rubber pad 606 can absorb some of the vibration, extending the overall service life.

[0019] In summary, when using this fatigue-resistant mineral casting bed with stress relief grooves, the first step is to... Figure 1 , Figure 2 and Figure 3 The structure shown allows for initial positioning of the guide rail during installation. First, the guide rail is placed in the mounting groove 4 and fitted against its side wall. Second, the position of the slider 604 below the adjustment hole 601 in the slide groove 603 is adjusted according to the mounting hole position on the guide rail, aligning the bolt with the threaded hole 605. Then, the bolts inside the guide rail are tightened, which moves the guide rail and slider 604 to the top surface of the guide rail mounting seat 2. At the same time, the buffer pad 602 buffers the slider 604 and the guide rail mounting seat 2, and the rubber pad 606 buffers the guide rail and the guide rail mounting seat 2. Then, during machine tool processing, when vibrations on the guide rail are transmitted to the bed body 1 via bolts, the buffer pad 602 and the rubber pad 606 absorb some of the vibrations, extending the overall service life. Finally, the arrayed first groove 301 and second groove 302 attract and release localized concentrated stress, making it a natural crack arrest zone, improving the overall fatigue resistance. Meanwhile, the silicone strip 303 prevents debris from entering.
