Description

Technical Field

[0001] The utility model relates to a rock slab cutting device, especially a rock slab cutting device that is convenient for measurement, safe to use, firmly holds and accurately cuts. Background Art

[0002] Building materials such as glass, tiles and rock slabs often need to be cut into corresponding shapes and sizes according to the needs of users during use; among them, rock slabs (Sintered Stone) are high-hardness plate bodies formed by vacuum extrusion and high-temperature sintering of natural raw materials, and have characteristics such as abrasion resistance, high temperature resistance and environmental friendliness... etc., and are one of the commonly used materials in the fields of architecture, decoration and furniture, etc.; because rock slabs are high-hardness plate bodies, the requirements for cutting accuracy and stability are higher than those of glass and tiles, etc., so they cannot be used with general cutting devices, but need to be used in conjunction with an existing rock slab cutting device.

[0003] The existing rock slab cutting device is provided with a track base, a cutter and several suction cups. The track base is in a long strip shape. The cutter is movably combined with the track base and is provided with an operating rod and a cutting wheel. The operating rod is swingably arranged on the cutter and is located on one side of the track base. The cutting wheel is arranged below the cutter and is connected to the operating rod, so that the cutting wheel can move relative to the track base along with the operating rod. The several suction cups are combined with the track base and are located on the other side of the track base. When the existing rock slab cutting device is in use, the track base is arranged on the top surface of a rock slab to be processed, and the track base is moved relative to the rock slab to be processed according to the position to be cut. When the track base moves to the required position, the track base is fixed on the top surface of the rock slab to be processed by the way that the several suction cups adsorb to the rock slab to be processed. At this time, by swinging the operating rod, the cutting wheel moves towards the rock slab to be processed along with the operating rod and cuts against the top surface of the rock slab to be processed, and by pushing the operating rod, the cutter is driven to move relative to the track base, so that the cutting wheel forms a cutting line on the rock slab to be processed, and the operation of the existing rock slab cutting device is completed.

[0004] However, although existing rock slab cutting devices can provide an effect of cutting rock slabs, when measuring the cutting position of existing rock slab cutting devices, one needs to reach their hand to the cutting wheel to measure the actual cutting position. Since the cutting wheel is located below the operating rod, it is not only inconvenient to measure, but also the cutting wheel has a sharp blade, which often causes injury to the user's hand and raises safety concerns. Further, although the existing rock slab cutting device can be conveniently assembled and disassembled by fixing it through the several suction cups, after long-term use, the suction cups are likely to affect the adsorption strength and stability with the rock slab to be processed due to material changes, and thus cannot stably set the track base on the rock slab to be processed, which will affect the cutting accuracy during subsequent cutting. Due to the above problems and deficiencies of the existing rock slab cutting device, there is room for improvement in the existing rock slab cutting device. Summary of the Utility Model

[0005] Therefore, to solve the problems that when using the existing rock slab cutting device, it is inconvenient to measure and one needs to contact the cutting wheel, which is likely to injure the user's hand, and the suction cups cannot stably adsorb after long-term use, which will affect the cutting accuracy, etc., the present utility model provides a rock slab cutting device. Through the configuration and improvement of the structure, when the user measures, they do not need to contact the cutting wheel, which can effectively avoid the situation of hand injury.

[0038] The present utility model provides a rock slab cutting device. Please refer to Figures 1 to 3In the preferred embodiment shown, the slab cutting device is provided with a track base 10, a cutting group 20 and two clamping groups 30, where:

[0039] Please refer to, for example, Figure 4 , Figure 5 and Figure 6 shown. The track base 10 is a long strip structure. Preferably, the track base 10 is made by the metal processing method of aluminum extrusion. The track base 10 is provided with two spaced engaging portions 11 at the top. The two engaging portions 11 extend along the length direction L of the track base 10. Each engaging portion 11 is provided with a clamping ring surface 111 on the outer surface. Each engaging portion 11 is a hollow structure and is provided with an opening 112 at both ends respectively. The track base 10 is provided with an extension connecting rod 12 at one opening 112 of each engaging portion 11. Through the extension connecting rods 12 provided on the two engaging portions 11, the track base 10 can be connected to another track base 10 with the same structure, thereby increasing the overall length to be suitable for slabs to be processed with different sizes. Further, please refer to, for example, Figure 4 and Figure 7 shown. The track base 10 is provided with a track groove 13 extending along the length direction L between the two engaging portions 11. An extension rail 14 is provided in the track groove 13. The extension rail 14 can be arranged between two adjacent track bases 10. And the extension rail 14 is provided with several locking members 141 on the top surface that abut against the two adjacent track bases 10 to connect the two adjacent track bases 10.

[0040] Please refer to, for example, Figure 5 and Figure 6 shown. The track base 10 is provided with at least one coupling portion 15 along the length direction L on the bottom surface. The at least one coupling portion 15 is provided with a long strip-shaped notch 151 on the bottom surface. Preferably, the track base 10 is provided with several spaced coupling portions 15 on the bottom surface. The track base 10 is provided with an anti-slip strip 16 in each coupling portion 15. The anti-slip strip 16 has elasticity and can be deformed in shape under the action of an external force. A part of each anti-slip strip 16 protrudes out of the track base 10 through the notch 151 of the corresponding coupling portion 15. Further, as shown in Figure 4 and Figure 5As shown, the track base 10 is provided with at least one end cover 17. The at least one end cover 17 is combined with one end of the track base 10 to close the ends of the two engaging portions 11, the track groove 13 and the several engaging portions 15, so as to prevent each of the extension connecting rods 12, the extension rail 14 and each anti-slip strip 16 from separating from the track base 10 through one end of the corresponding engaging portion 11, track groove 13 and engaging portion 15. Among them, the at least one end cover 17 is provided with several closing members 171 on the inner side surface, which are respectively engaged with the two engaging portions 11, the track groove 13 and each engaging portion 15. Each of the closing members 171 can be in structural forms such as cylindrical, cross-shaped or U-shaped, which are not limited herein. Preferably, the track base 10 is provided with one of the said end covers 17 at each of the two ends.

[0041] Please refer to, for example, Figures 2 to 4 As shown, the cutting group 20 is combined with the track base 10 and is provided with a cutter 21 and two measuring seats 22. Among them, the cutter 21 can move relative to the track base 10 and is provided with a sliding seat 23, an operating rod 24 and a cutting wheel 25. The sliding seat 23 is movably combined with the track base 10 and is provided with several pulleys 231. The several pulleys 231 are arranged at intervals on both sides of the bottom of the sliding seat 23. Among them, the number of pulleys 231 on both sides can be the same or different, which is not limited herein. Further, the pulleys 231 on the same side are engaged with one of the engaging portions 11, and the pulleys 231 on the other side are engaged with the other engaging portion 11, so that the sliding seat 23 is arranged on the track base 10 in a manner of being combined with the two engaging portions 11 through the several pulleys 231. Still further, each of the pulleys 231 is annularly recessed on the outer surface with an annular arc surface 232 that matches the engaging ring surface 111 of the corresponding engaging portion 11, so that each of the pulleys 231 can rotate on the corresponding engaging portion 11, thereby driving the sliding seat 23 to move relative to the track base 10. Please refer to, for example, Figure 2 and Figure 3 As shown, the operating rod 24 is swingably combined with the sliding seat 23 and is located on one side of the sliding seat 23. Preferably, the operating rod 24 is obliquely arranged on one side of the sliding seat 23. The cutting wheel 25 is rotatably arranged below the operating rod 24 and is located on one side of the track base 10.

[0042] Please refer to, for example, Figures 4 to 6As shown, the two measuring seats 22 are movably arranged on the rail seat 10 and are respectively located on both sides of the cutter 21. Preferably, the two measuring seats 22 are respectively arranged at positions near the two ends of the rail seat 10. Each measuring seat 22 is provided with two clamping arms 26, a positioning arm 27 and a push handle 28. The two clamping arms 26 are combined and extend in opposite directions and are respectively combined with the two engaging parts 11 of the rail seat 10, so that the measuring seat 22 can be combined with the rail seat 10 through the two clamping arms 26. The positioning arm 27 is combined with one of the clamping arms 26 and extends outward and downward to one side of the bottom surface of the rail seat 10. The positioning arm 27 and the cutting wheel 25 are on the same side of the rail seat 10. The positioning arm 27 is provided with a horizontally arranged reference plate 271 at its free end. The reference plate 271 extends along the width direction W of the rail seat 10 and the extension line of the outer side surface 272 of its free end is as Figure 2 and Figure 3 shown, and is arranged in a straight line with the cutting edge of the cutting wheel 25, that is, the cutting line formed by the cutting edge of the cutting wheel 25 and the outer side surface 272 of the reference plate 271 are on the same straight line. The push handle 28 is arranged at the top of the measuring seat 22 and is located between the two clamping arms 26, so that the user can move the measuring seat 22 relative to the rail seat 10 through the push handle 28. Preferably, the outer surface of the push handle 28 is provided with several notches 281 to increase the contact area and friction between the user's hand and the push handle 28, so that the user can easily and conveniently push the measuring seat 22.

[0043] Please refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, the two clamping groups 30 are combined with the rail seat 10 and are respectively located at both ends of the bottom surface of the rail seat 10. Each clamping group 30 is provided with a clamping seat 31 and a pushing rod 32, as Figure 5 and Figure 8As shown, the clamping seat 31 is provided with a base 33 and two clamping arms 34. The base 33 is longitudinally penetrated with a coupling hole 331, and the coupling hole 331 faces the bottom surface of the rail seat 10. The two clamping arms 34 protrude upward from the top surface of the base 33 and are respectively located on both sides of the base 33. The two clamping arms 34 are clamped and coupled with the two side edges of the rail seat 10. Each clamping arm 34 is provided with a hook portion 341 and an avoidance groove 342. Among them, the hook portion 341 is provided at the free end of the clamping arm 34 and abuts against a side edge of the rail seat 10, so that the clamping seat 31 is clamped and coupled with the rail seat 10 through the hook portions 341 of the two clamping arms 34. The avoidance groove 342 is provided on the side of the clamping arm 34 facing the rail seat 10 and is between the hook portion 341 and the base 33. The pushing rod 32 is rotatably coupled with the base 33 of the clamping seat 31 and can approach or move away from the bottom surface of the rail seat 10. The top end of the pushing rod 32 extends above the base 33 through the coupling hole 331 of the base 33 and is located between the two clamping arms 34. The pushing rod 32 is provided with a pushing disc 35 at the top end. The bottom end of the pushing rod 32 is provided below the base 33 and is provided with a turning handle 36. By turning the turning handle 36, the pushing rod 32 can be driven to rotate relative to the base 33 to change the distance between the pushing disc 35 and the rail seat 10. Further, the coupling hole 331 has an internal thread, and the pushing rod 32 is provided with an external thread on the outer surface that combines with the internal thread. Still further, the measuring seat 22 and each clamping seat 31 are arranged in a hollowed-out manner, which can not only make the positioning arm 27 of the measuring seat 22 and the base 33 of each clamping seat 31 elastic, but also reduce the manufacturing cost, and can greatly reduce the overall weight of the rock slab cutting device of the present invention, making it convenient for users to transport and store.

[0044] Please also refer to Figure 9 and Figure 10 As shown, when using the rock slab cutting device of the present invention; first, the rail seat 10 is set on a rock slab 50 to be processed, so that each anti-slip strip 16 on the bottom surface of the rail seat 10 is as Figure 13 shown and abuts against the top surface of the rock slab 50 to be processed, so that the rail seat 10 can be stably abutted against the top surface of the rock slab 50 to be processed, and the rock slab 50 to be processed is combined with the avoidance grooves 342 of the clamping arms 34 of each clamping seat 31, so that the rock slab 50 to be processed is as Figure 14 shown and is located between the rail seat 10 and the pushing discs 35 of each pushing rod 32. At this time, as Figure 11 and Figure 12As shown, since the outer side surface 272 of the reference plate 271 of each positioning arm 27 is on the same straight line as the cutting edge of the cutting wheel 25, when the user measures the position of the size to be cut on the to-be-processed rock slab 50, there is no need to measure through the cutting edge of the cutting wheel 25 anymore. Instead, the outer side surface 272 of the reference plate 271 of each measuring seat 22 can be used as the measuring position for the cutting size. This can not only facilitate and accurately measure the cutting size, but also prevent the user from coming into contact with the cutting wheel 25 and getting injured, greatly improving the safety of use.

[0045] Furthermore, after the user confirms the position of the size to be cut on the to-be-processed rock slab 50 by measuring the outer side surface 272 of each reference plate 271, as Figure 14 shown, by rotating each turning handle 36, each pushing rod 32 can be moved towards the track seat 10, so that each pushing disk 35 abuts against the bottom surface of the to-be-processed rock slab 50. Then, the to-be-processed rock slab 50 can be pushed upwards by each pushing disk 35, and the track seat 10 can be firmly clamped and fixed on the to-be-processed rock slab 50 by each clamping arm 34 clamping downwards on the track seat 10. At this time, please refer to Figure 15 shown, the user can hold the operating rod 24 and swing downwards relative to the sliding seat 23 to drive the cutting wheel 25 into contact with the top surface of the to-be-processed rock slab 50. By the way that each pulley 231 can rotate relative to the two engaging parts 11, the sliding seat 23 is pushed along the track seat 10 by the operating rod 24, and as Figure 15 and Figure 16A shown, a cutting line 60 is formed on the to-be-processed rock slab 50 by the cutting wheel 25. Among them, as Figure 16B shown, the cutting line 60 is tangent to the outer side surface 272 of the reference plate 271. After the above operations, an accurate size can be cut on the to-be-processed rock slab 50.

[0046] Furthermore, please refer to Figure 13 and Figure 17 shown, each measuring seat 22 of the cutting group 20 is arranged on the track seat 10 by the way that the two clamping arms 26 are respectively combined with the two engaging parts 11. Therefore, the user can adjust the positions of the two measuring seats 22 relative to the track seat 10 as needed by pushing the push handle 28, enabling the user to flexibly and conveniently measure the size of the rock slab 50 to be cut by the two measuring seats 22.

[0047] By means of the above technical means, when the rock plate cutting device of the present utility model is in use, not only can the outer side surface 272 of the reference plate 271 of the positioning arm 27 of each measurement base 22 be in a spatial state in a straight line with the cutting edge of the cutting wheel 25, enabling the user to measure the size position to be cut only through each reference plate 271, without the need to measure the cutting edge of the cutting wheel 25 anymore. This can not only facilitate and accurately measure the cutting size, but also avoid the situation where the user comes into contact with the cutting wheel 25 and gets injured, greatly improving the safety of use. Further, through the clamping arms 34 and the pushing rods 32 of the two clamping seats 31, the track seat 10 can be firmly clamped and fixed on the rock plate 50 to be processed, and the accuracy of cutting will not be affected by the deviation of the track seat 10 during subsequent cutting processing. Furthermore, each anti-slip strip 16 located on the bottom surface of the track seat 10 can make the track seat 10 more firmly attached to the rock plate 50 to be processed, thereby providing a rock plate cutting device that is convenient for measurement, safe to use, firmly clamped, and accurately cut.

[0048] The above description is only a preferred embodiment of the present utility model and does not impose any form of limitation on the present utility model. Although the present utility model has been disclosed above with a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art, without departing from the technical solution of the present utility model, can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes. However, as long as it does not depart from the technical solution of the present utility model, any simple modification, equivalent change, and modification made to the above embodiment based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
