Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a stone sawing device. Background Technology

[0002] Stone, as a high-end building decoration material, is widely used in interior and exterior decoration design, curtain wall decoration, and public facility construction. Stone processing includes processes such as sawing, cutting, grinding, and drilling of rocks; for slabs, the main process is sawing.

[0003] Currently, there are two types of sawing machines used for stone processing: one is the frame-type sand-adding stone sawing machine, which has a huge frame with multiple saw blades installed inside. During the sawing process, abrasives such as steel grit, cast iron grit, or garnet grit are continuously added to the saw kerf. The stone is processed by the grinding action of the abrasives. Therefore, the sawing efficiency is low, and the saw blades are prone to fatigue breakage during the sawing process. The saw blades are not completely covered, which poses certain operational safety hazards. The other is the disc-type diamond stone sawing machine, which uses a bridge-type frame and is equipped with a circular saw blade with diamond to cut the stone. Although the cutting speed is relatively fast, the cutting depth is only one-third of the saw blade diameter, which limits the cutting depth of stone processing and the processing range.

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a stone sawing device.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] This utility model discloses a stone sawing device, including a workbench and a guide rail fixed below the workbench. A motor is movably connected above the guide rail, and the output end of the motor is connected to a saw blade spindle via a belt. A saw blade is connected to one end of the saw blade spindle. A saw groove is formed on the workbench, and the saw blade extends from the saw groove. A stone fixing mechanism is fixedly connected to the workbench. An upper protective cover is fixed above the workbench, and a lower protective cover is provided at the bottom of the workbench. A cavity for protecting the saw blade is formed between the lower protective cover and the upper protective cover.

[0007] As a preferred embodiment of this utility model, a feeding rack is connected to one side of the workbench, and a number of equally spaced rolling rollers are installed on the feeding rack.

[0008] As a preferred embodiment of this utility model, a slide block is slidably connected to the guide rail, the motor is fixed to the upper surface of the slide block, and a spindle bracket for mounting the saw blade spindle is also fixed on the slide block. One end of the saw blade spindle is fixedly connected to a spindle pulley, and the spindle pulley is connected to the output end of the motor via a belt.

[0009] As a preferred embodiment of this utility model, a drive cylinder is fixedly connected to one side of the guide rail, and the movable end of the drive cylinder is fixedly connected to one side of the slide block, for driving the slide block to move horizontally along the guide rail.

[0010] As a preferred technical solution of this utility model, the stone fixing mechanism includes a cylinder fixing plate, which is fixed on the workbench. Two parallel pressing arms are movably connected to the cylinder fixing plate through guide sleeves. Pressing cylinders are fixedly connected to the two pressing arms respectively. The pressing cylinders are symmetrically arranged along the saw blade. A pressing head for pressing the upper surface of the stone is fixedly connected to the movable end of the pressing cylinder.

[0011] As a preferred technical solution of this utility model, the stone fixing mechanism further includes two parallel side pressure cylinders. The side pressure cylinders are fixed on the worktable and are perpendicular to the cylinder fixing plate. The side pressure cylinders are symmetrically arranged along the saw blade.

[0012] As a preferred embodiment of this utility model, the bottom of the lower protective cover is also provided with a chip outlet, and the bottom of the chip outlet is connected to a chip groove for collecting sawdust.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The upper and lower protective covers form a cavity that surrounds the saw blade. When the saw blade is not in use, it is completely inside the upper protective cover. When the saw blade is in use, it moves between the upper and lower protective cover supports, making it less likely for workers to touch the saw blade and improving operational safety.

[0015] 2. The pressing cylinder on the pressing arm quickly presses the upper surface of the stone, while the side cylinder quickly presses the stone laterally, realizing rapid clamping of the stone and improving clamping efficiency. At the same time, the fixed position of the side cylinder is adjustable, which increases the sawing width of the stone. The drive cylinder drives the saw blade to move horizontally, realizing a larger sawing depth and increasing the processing range of the stone by the device. Attached Figure Description

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] In the attached diagram, all identical reference numerals refer to the same components.

[0025] like Figure 1-5 As shown, this utility model provides a stone sawing device, including a workbench 1 and a guide rail 2 fixed below the workbench 1. A motor 3 is movably connected above the guide rail 2. The output end of the motor 3 is connected to a saw blade spindle 4 via a belt. A saw blade 5 is connected to one end of the saw blade spindle 4. A saw groove is provided on the workbench 1, and the saw blade 5 extends out from the saw groove. A stone fixing mechanism 6 is fixedly connected to the workbench 1. An upper protective cover 7 is fixed above the workbench 1, and a lower protective cover 8 is provided at the bottom of the workbench 1. A cavity for protecting the saw blade 5 is formed between the lower protective cover 8 and the upper protective cover 7.

[0026] In this embodiment, the side of the lower protective cover 8 is fixed to the slide 11. The upper half of the lower protective cover 8 is semi-circular and completely surrounds the lower half of the saw blade 5. The lower half of the lower protective cover 8 is provided with a chip-collecting port for communicating with the chip groove 21. The arc-shaped inclined lower protective cover 8 can better collect the chips generated during the cutting process of the saw blade 5.

[0027] Furthermore, a feeding rack 9 is connected to one side of the workbench 1, and several equally spaced rolling rollers 10 are installed on the feeding rack 9.

[0028] In this embodiment, after the stone is placed on the feeding rack 9, it can be easily moved to the worktable 1 by the sliding of the rolling roller 10.

[0029] Furthermore, a slide block 11 is slidably connected to the guide rail 2, and the motor 3 is fixed to the upper surface of the slide block 11. A spindle bracket 12 for mounting the saw blade spindle 4 is also fixed on the slide block 11. One end of the saw blade spindle 4 is fixedly connected to a spindle pulley 13, and the spindle pulley 13 is connected to the output end of the motor 3 via a belt.

[0030] In this embodiment, the motor 3 and the spindle support 12 move together on the slide 11, the saw blade spindle 4 is fixedly installed on the spindle support 12, and the output end of the motor 3 is connected to the spindle pulley 13 through the pulley, thereby driving the saw blade spindle 4 to rotate, and then driving the saw blade 5 to rotate.

[0031] Furthermore, a drive cylinder 14 is fixedly connected to one side of the guide rail 2. The movable end of the drive cylinder 14 is fixedly connected to one side of the slide block 11, which is used to drive the slide block 11 to move horizontally along the guide rail 2.

[0032] In this embodiment, the drive cylinder 14 can drive the slide 11 on the guide rail 2 to move horizontally, thereby driving the motor 3 on the slide 11 and the spindle support 12 to move together, further driving the saw blade spindle 4 and saw blade 5 mounted on the spindle support 12 to move together, thereby realizing the feeding sawing function of the saw blade 5.

[0033] Furthermore, the stone fixing mechanism 6 includes a cylinder fixing plate 15, which is fixed on the workbench 1. Two parallel pressing arms 16 are movably connected to the cylinder fixing plate 15 via guide sleeves. Pressing cylinders 17 are fixedly connected to the two pressing arms 16 respectively. The pressing cylinders 17 are symmetrically arranged along the saw blade 5. The movable end of the pressing cylinder 17 is fixedly connected to a pressing head 18 for pressing the upper surface of the stone.

[0034] In this embodiment, the two pressing arms 16 can extend to a certain length according to the width of the stone, and the pressing cylinder 17 can move horizontally together with the pressing arms 16. The pressing cylinder 17 can control the up and down movement of the pressing head 18, thereby ensuring that the upper surface of the stone can be stably pressed by the pressing head 18. In addition, the pressing head 18 is circular in shape and is made of polyurethane with a certain degree of elasticity, which can protect the stone surface from scratches.

[0035] Furthermore, the stone fixing mechanism 6 also includes two parallel side pressure cylinders 19. The side pressure cylinders 19 are fixed on the workbench 1 and are arranged perpendicularly to the cylinder fixing plate 15. The side pressure cylinders 19 are symmetrically arranged along the saw blade 5. The movable end of the side pressure cylinder 19 is fixed with a pressing block 20 for pressing the side of the stone.

[0036] In this embodiment, "before sawing the stone, the fixed position of the side pressure cylinder 19 can be adjusted according to the width of the stone, increasing the distance between the side pressure cylinder 19 and the cylinder fixing plate 15, so as to increase the processing range of the sawing device. The side pressure cylinder 19 can drive the clamping block 20 to press the side of the stone, preventing the stone from shifting during sawing. The clamping block 20 is square in shape and is made of polyurethane with a certain degree of elasticity, which can protect the side of the stone. When the stone moves to the sawing position, the side pressure cylinder 19 first presses the side of the stone laterally, and then the pressing cylinder 17 presses the upper surface of the stone, thereby realizing the quick clamping and stable fixation of the stone. Then, the drive cylinder 14 drives the saw blade 5 to move horizontally to complete the sawing of the stone."

[0037] Furthermore, the bottom of the lower protective cover 8 is provided with a chip outlet, and the bottom of the chip outlet is connected to a chip trough 21 for collecting sawdust. Preferably, the chip trough 21 is rectangular and its two ends are fixed to the support legs of the workbench 1. When the lower protective cover 8 moves horizontally, the chips falling from the chip outlet can fall completely into the chip trough 21.

[0038] In this embodiment, by providing a chip groove 21 at the bottom of the lower protective cover 8, the arc-shaped inclined lower protective cover 8 can better collect the chips generated during the cutting of stone by the saw blade 5, so that the chips generated during the cutting process can flow along the lower protective cover 8 into the interior of the chip groove 21.

[0039] This invention relates to a stone sawing device. A pressure cylinder mounted on the pressure arm quickly presses the upper surface of the stone, while a lateral cylinder simultaneously presses the stone laterally, achieving rapid clamping. The adjustable position of the lateral cylinder increases the sawing width, and the horizontal movement of the saw blade driven by a drive cylinder achieves a greater sawing depth, thus increasing the device's stone processing capacity.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
