Marble cutting fixing mechanism

Abstract

This utility model discloses a marble cutting and fixing mechanism, including a base and a fastening plate. The base has symmetrical longitudinal grooves at the center of both sides of its top. By employing horizontal and vertical plates, after the base is fixed, the operator only needs to place the marble to be cut on top and push the surrounding horizontal and vertical plates. The horizontal and vertical plates then fit snugly around the marble, forming a clamping operation. Because the bottom of the vertical plate has a receiving groove for the horizontal plate to move, multiple plates can be easily adjusted without interference, thus enabling the fixing of marbles of different sizes. This facilitates better use. Furthermore, the overall structure is simple, requiring only adjustment of the plates, without involving intelligent structures, resulting in low maintenance costs and low operation difficulty. It has the advantages of being labor-saving, simple in structure, and easy to use.

Description

Technical Field

[0001] This utility model relates to the field of marble processing technology, and more specifically, to a marble cutting and fixing mechanism. Background Technology

[0002] Marble originally referred to white limestone with black patterns produced in Dali, Yunnan Province. Its cross-section can form a natural ink wash landscape painting. In ancient times, marble with well-formed patterns was often selected to make painted screens or inlaid paintings. Later, the name marble gradually came to refer to all limestone with various colors and patterns used as building decoration materials. White marble is generally called Hanbaiyu, but the white marble used for making sculptures in the West is also called marble. Marble is very beautiful after polishing. It is mainly used to process various shapes and slabs for building walls, floors, platforms, and columns. It is also often used as a material for commemorative buildings such as monuments, towers, and statues. Marble can also be carved into handicrafts, stationery, lamps, utensils, and other practical art pieces. Cutting is an indispensable step in the processing of marble.

[0003] Currently, most marble cutting operations rely on pneumatic clamps for fixing the marble. However, pneumatic clamps have complex structures, are difficult to operate and have high maintenance costs. They require personnel with extensive processing experience, which hinders their widespread adoption. Furthermore, adjustments are time-consuming and labor-intensive, resulting in less than ideal overall performance and room for improvement.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a marble cutting and fixing mechanism, which has the advantages of being labor-saving to operate, having a simple structure, and being easy to use, thereby solving the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the advantages of labor-saving operation, simple structure, and low difficulty of use, the specific technical solution adopted by this utility model is as follows:

[0009] A marble cutting and fixing mechanism includes a base and a fastening plate. The base has symmetrical longitudinal grooves at the middle of the top two sides, and a transverse groove between the longitudinal grooves. Slider blocks are slidably connected inside the longitudinal and transverse grooves. A transverse plate and a longitudinal plate are respectively installed on the top of the slider. A plug rod is slidably connected at the middle of the top of the transverse plate and the middle of the top of the longitudinal plate. A spring is sleeved on the outer periphery of the plug rod. Receiving grooves are symmetrically opened at the bottom of the two sides of the longitudinal plate.

[0010] Furthermore, finite grooves are symmetrically provided on both sides of the transverse and longitudinal grooves.

[0011] Furthermore, limit blocks are symmetrically installed on both sides of the slider, and the limit blocks are slidably connected to the limit grooves.

[0012] Furthermore, several sets of insertion holes are provided at the bottom of both the transverse and longitudinal grooves.

[0013] Furthermore, several sets of fastening plates are symmetrically welded to the bottom of the four sides of the base, and fastening holes are opened on the surface of the fastening plates.

[0014] Furthermore, the height of the horizontal plate is less than the height of the receiving groove.

[0015] Furthermore, the insertion rod and the insertion hole are on the same straight line.

[0016] Furthermore, rubber pads are provided on both the surface of the horizontal plate and the surface of the vertical plate.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a marble cutting and fixing mechanism, which has the following advantages:

[0019] This utility model employs horizontal and vertical plates. After the base is fixed, the operator only needs to place the marble to be cut on top and push the horizontal and vertical plates around it. At this time, the horizontal and vertical plates can fit against the marble, thus forming a relative clamping operation. Since the bottom of the vertical plate has a receiving groove for the horizontal plate to move, multiple sets of plates can be adjusted smoothly when they move relative to each other without interfering with each other. This enables the fixing of marbles of different sizes, making it easier to use. At the same time, the overall structure is simple, requiring only the adjustment of the plates, without involving intelligent structures, resulting in lower maintenance costs and lower operation difficulty. It is more practical and has the advantages of labor-saving operation, simple structure, and low difficulty of use. Attached Figure Description

[0027] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0028] According to an embodiment of the present invention, a marble cutting and fixing mechanism is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the marble cutting and fixing mechanism according to an embodiment of the present invention includes a base 1 and a fastening plate 13. The base 1 has symmetrically arranged longitudinal grooves 3 at the middle positions of both sides of its top, and transverse grooves 4 between the longitudinal grooves 3. Sliding sliders 6 are slidably connected inside both the longitudinal grooves 3 and the transverse grooves 4. A transverse plate 2 and a longitudinal plate 5 are respectively installed at the top of the sliders 6. Insert rods 9 are slidably connected at the middle positions of the top of both the transverse plate 2 and the longitudinal plate 5. Springs 10 are sleeved around the outer periphery of the insert rods 9. Receiving grooves 14 are symmetrically arranged at the bottom positions of both sides of the bottom surface of the longitudinal plate 5. Regarding the transverse grooves 4, longitudinal grooves 3, and sliders 6: A transverse groove 4 is opened along the length direction at the top of the base 1, and two longitudinal grooves 3 are opened along the width direction (perpendicularly intersecting the transverse groove 4). Sliding sliders 6 are slidably connected inside the grooves, with a clearance fit (0.1mm) between the sliders 6 and the grooves. Limiting blocks 7 are symmetrically welded to both sides of the sliders 6, embedding into the limiting grooves 8 on both sides of the grooves to prevent the sliders 6 from falling out of the grooves. Regarding the transverse plates 2, longitudinal plates 5, and receiving grooves 14: A transverse plate 2 is welded to the top of the sliders 6 on the transverse groove 4. Plate 2, the top of the slider 6 on the longitudinal groove 3 is welded with a longitudinal plate 5. The bottom of the longitudinal plate 5 has symmetrical receiving grooves 14 on both sides. The height of the horizontal plate 2 is less than the depth of the receiving groove 14, ensuring that the horizontal plate 2 and the longitudinal plate 5 can pass through the receiving groove 14 when they intersect (no interference, gap at the intersection ≤1mm); Size adaptability: the horizontal plate 2 and the longitudinal plate 5 can move freely along the groove, and the adjustment range covers the entire area of ​​the base 1, which can fix marble of different sizes; No interference in movement: the size difference between the receiving groove 14 and the horizontal plate 2 ensures that when the longitudinal plate 5 moves, the horizontal plate 2 can be completely inserted into the receiving groove 14, solving the problem of "jamming at the intersection" in traditional right-angle clamping (reduced jamming rate); Flexible clamping: the horizontal plate 2 (lateral clamping) and the longitudinal plate 5 (longitudinal clamping) cooperate to form a "rectangular enclosure" from four directions, fixing the marble by friction (meeting the anti-slip requirements during cutting); Convenient operation: the low-resistance sliding and interference-free design of the slider 6 allows a single person to easily push the horizontal plate 2 / vertical plate 5, shortening the adjustment time compared to traditional clamps (improved efficiency).

[0030] like Figure 1 As shown, limit grooves 8 are symmetrically opened on both sides of the transverse groove 4 and the longitudinal groove 3.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, limit blocks 7 are symmetrically installed on both sides of the slider 6, and the limit blocks 7 are slidably connected to the limit grooves 8. The limit blocks 7 and the limit grooves 8 form a limit structure to ensure stable sliding.

[0032] like Figure 1As shown, several sets of insertion holes 11 are provided at the bottom of the transverse groove 4 and the longitudinal groove 3. Insert rod 9, spring 10 and insertion holes 11: The top center of the transverse plate 2 and the longitudinal plate 5 are provided with sliding holes to slide the insertion rod 9. The spring 10 is sleeved on the outer periphery of the insertion rod 9. The two ends of the spring 10 are welded to the limiting ring of the insertion rod 9 and the surface of the plate body, respectively. Insert holes 11 are evenly provided at the bottom of the transverse groove 4 and the longitudinal groove 3, coaxial with the insertion rod 9 (deviation ≤0.5mm), forming positioning points; Locking reliability: The spring 10 pushes the insertion rod 9 into the insertion hole 11 in the natural state, which can resist the vibration during marble cutting (no loosening); Lifting the insertion rod 9 can compress the spring 10 to unlock. The operating force is less than that of traditional bolt locking, realizing the "efficiency-saving" advantage; Positioning accuracy: The uniformly spaced insertion holes 11 improve the positioning accuracy of the horizontal plate 2 / vertical plate 5, meeting the positioning requirements for marble cutting (cutting error is usually allowed to be ±1mm), eliminating the need for millimeter-level fine-tuning (reducing the difficulty of use); Quick fixing: The elastic locking of "insertion rod 9 + spring 10" replaces traditional bolts or pneumatic clamps, achieving "push-release" two-step fixing (no tools required), shortening the locking time; Stepless adjustment: Multiple sets of insertion holes 11 adapt to different sizes of marble (e.g., one setting every 50mm), with an omnidirectional adjustment range, such as 50-800mm (horizontal) and 50-600mm (vertical), offering better versatility than fixed-size clamps (which only adapt to 1-2 sizes).

[0033] like Figure 1 As shown, several sets of fastening plates 13 are symmetrically welded to the bottom of the four sides of the base 1. Fastening holes 12 are opened on the surface of the fastening plates 13. Four sets of fastening plates 13 (Q235 steel plate, 100mm long × 50mm wide × 10mm thick) are symmetrically welded to the bottom of the four sides of the base 1. Each set of fastening plates 13 has two fastening holes 12 (only one is shown in the figure, φ12mm). They are fixed to the cutting table surface by expansion bolts (to prevent the base 1 from shaking during cutting). Installation stability: The fastening plates 13 are distributed at the four corners of the base 1 to form a symmetrical force-bearing structure, which improves the fit with the table surface and can withstand the impact force during cutting. Stable foundation: The self-weight of the base 1, combined with the rigid fixation of the fastening plates 13, provides stable support for the entire mechanism and avoids loosening due to vibration during marble cutting. Universal compatibility: The design of the fastening holes 12 allows the base 1 to be installed on various cutting table surfaces (such as cement table, steel plate table), improving compatibility and eliminating the need for custom-made table surfaces.

[0034] like Figure 1 and Figure 2 As shown, the height of the horizontal plate 2 is less than the height of the receiving groove 14. The height of the receiving groove 14 is set to avoid interference with the movement of the horizontal plate 2 and to ensure the smooth use of the structure.

[0035] like Figure 1 As shown, the insertion rod 9 and the insertion hole 11 are on the same straight line. The straight line ensures that the insertion rod 9 can be smoothly inserted into the insertion hole 11, thereby ensuring that the structure can be successfully limited and fixed.

[0036] like Figure 1 As shown, rubber pads are provided on the surfaces of both the horizontal plate 2 and the vertical plate 5. The rubber pads (such as nitrile rubber, 3mm thick, Shore A hardness 60A) are adhered to the surfaces of the horizontal plate 2 and vertical plate 5 that contact the marble, and are fixed with strong adhesive, covering the contact area of ​​the plates (100% coverage). Friction enhancement: The rubber pad surface has anti-slip textures (0.5mm deep), increasing the static friction coefficient with the marble (compared to only 0.3 for direct contact between steel and marble), improving the anti-slip effect under the same clamping force, and preventing the marble from sliding during cutting. Buffer protection: The rubber pad compression is 1-2mm, which can absorb the impact force during clamping and prevent the horizontal plate 2 from slipping. The hard contact of the longitudinal plate 5 causes damage to the marble edges and corners (reducing the breakage rate); Dual protection: The dual function of anti-slip and anti-breakage ensures cutting safety (no slippage) and protects the appearance of the marble (especially suitable for polished marble); Fixing preparation: Fix the base 1 to the cutting table with the fastening plate 13 and bolts, ensuring it is level (levelness error ≤ 0.5mm), lift the insertion rod 9 (compression spring 10) of the horizontal plate 2 and the longitudinal plate 5, and push the slider 6 to move the horizontal plate 2 and the longitudinal plate 5 to the maximum opening position (away from the center); Clamping operation: Place the marble to be cut in the center of the base 1, and adjust the position so that the cutting line is aligned with the cutting equipment. Push the two horizontal plates 2 towards the horizontal edge of the marble until the rubber pads are in contact (the clamping force should be such that the marble does not wobble). Release the insert rod 9 to insert it into the corresponding insertion hole 11 (a "click" sound confirms locking). Push the two vertical plates 5 towards the vertical edge of the marble (the horizontal plate 2 passes through the receiving groove 14 of the vertical plate 5 without interference). After the rubber pads are in contact, release the insert rod 9 to lock it. Cutting and resetting: Start the cutting equipment to complete the cutting (the marble does not slip or break during the process). After cutting, lift the insert rod 9 to unlock, push open the horizontal plate 2 and the vertical plate 5, and remove the marble. If other sizes need to be cut, repeat the above steps. Easy to operate. Features: Purely mechanical structure (no pneumatic / electric components), fixing is achieved through "push-release", requiring no professional skills (ordinary people can operate it proficiently in 5 minutes), solving the problems of "requiring training and difficult maintenance" of traditional pneumatic clamps; Cost advantage: material cost ≤200 yuan (traditional pneumatic clamps ≥1000 yuan), no energy consumption, maintenance only requires replacing worn rubber pads (cost ≤10 yuan), suitable for small and medium-sized stone processing plants; Through the collaborative design of "interference-free adjustment + elastic locking + anti-slip protection", this mechanism achieves efficient and labor-saving marble fixing with a simple structure, especially suitable for scenarios sensitive to operation difficulty and cost.

[0037] Working principle: In actual use, the base 1 can be fixed to the cutting table by the fastening plates 13 around the perimeter and corresponding fasteners (such as bolts), which facilitates subsequent cutting operations. Then, the person can place the marble to be cut on the top of the base 1, and then pull the vertical plates 5 and horizontal plates 2 on both sides to make the above structure fit against the perimeter of the marble, and then fix it by relative compression. When fixing and adjusting, simply pull up the insert rod 9 on the surface and push the plate to move accordingly to adjust the position. It is very convenient to operate and has low operation difficulty. The person does not need to have professional experience to fix it. It is very flexible to use. The device as a whole has the advantages of labor-saving operation, simple structure and low difficulty of use.
