[0002] A concrete slab cutting saw is a mechanical device specifically designed for cutting and processing concrete slabs. It uses saw blades and other cutting components, driven by mechanical power, to achieve precise cutting of concrete slabs. It can cut slabs of specific sizes and shapes according to requirements and is widely used in construction, building materials processing and other fields. It can improve the efficiency and accuracy of concrete slab cutting, reduce the intensity of manual operation, and is an important piece of equipment in the concrete slab processing process.

[0003] When cutting concrete slabs, the cutting line needs to be marked first by positioning and laying out the lines. Then, the sawing machine parameters are adjusted and the slab is fixed. The equipment is then started, and the saw blade is allowed to cut at a uniform speed along the marked line. Water is sprayed simultaneously during the process to cool down and reduce dust. The machine is then stopped after the cutting is completed.

[0004] The existing technology has the following drawbacks: existing cutting equipment often suffers from insufficient flexibility in positioning mechanism, making it difficult to adapt to different sized plates, resulting in time-consuming adjustments, poor positioning accuracy, and affecting processing quality. In addition, existing equipment lacks protective devices, making it difficult to shield the flying debris during cutting and ensure operational safety. Therefore, a sawing machine for cutting concrete slabs is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a sawing machine for cutting concrete slabs, comprising a worktable 1, with a slide rail 2 fixedly connected to the top of the worktable 1. The slide rail 2 is a rigid track with a specific cross-sectional shape, serving as the movement path and providing stable guidance and support for a support 3. A support 3 is slidably connected to the outer wall of the slide rail 2, and the support 3 is a movable part that cooperates with the slide rail 2, directly connected to the driven load. The displacement of the load is achieved through relative movement with the slide rail 2. A cutting machine 4 is provided on the inner wall of the support 3, and the rear inner wall of the worktable 1 is connected by a movable spring. Spring 12 is elastically connected to positioning plates 5. When the two sets of positioning plates 5 approach each other, the movable spring 12 is stretched. During reset, the elastic force of the movable spring 12 carries the positioning plates 5 back to their original position. A limit mechanism is provided on the inner wall of the positioning plates 5. The bottom end of the positioning plates 5 is hinged to a slider 7 via a hinge rod 6. Since the length of the hinge rod 6 is fixed, when the slider 7 moves one end of the hinge rod 6 to the left, the other end of the hinge rod 6 will cause the two sets of positioning plates 5 to approach each other. When the slider 7 moves one end of the hinge rod 6 to the right, the other end of the hinge rod 6 will cause the two sets of positioning plates 5 to separate.

[0034] Reference Figures 1-3 The inner wall of the slider 7 is threadedly connected to a threaded rod 8. The slider 7 is provided with a thread that matches the threaded rod 8. The smooth surface of the threaded rod 8 is rotatably connected to a stop block 9. The stop block 9 has a slot corresponding to the threaded rod 8, so that the stop block 9 does not rotate with the threaded rod 8. The inner wall of the bracket 3 is fixedly connected to a telescopic rod 10, which is a free telescopic mechanism. The top of the worktable 1 is provided with a protective component. The limiting mechanism includes an insert block 11, which is slidably connected to the inner wall of the positioning plate 5. The positioning plate 5 has a slot corresponding to the insert block 11, so that the insert block 11 can move vertically. The inner side wall of the insert block 11 is elastically connected to the positioning plate 5 through a moving spring 13. When the insert block 11 moves upward, the moving spring 13 is compressed. When resetting, the elastic force of the moving spring 13 is used to reset the insert block 11.

[0035] Reference Figure 1 , Figure 3 and Figure 4 The protective component includes a limiting block 14, which is slidably connected to the top of the worktable 1. The worktable 1 has a slot corresponding to the limiting block 14, allowing the limiting block 14 to move left and right. The right side wall of the limiting block 14 is elastically connected to the worktable 1 via a positioning spring 15. When the limiting block 14 moves to the right, the positioning spring 15 is compressed. When resetting, the elastic force of the positioning spring 15 carries the limiting block 14 back to its original position. A protective plate 16 is inserted into the outer wall of the limiting block 14. The protective plate 16 has two sets of slots corresponding to the limiting block 14. The protective plate 16 is slidably connected to the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the protective plate 16, allowing the protective plate 16 to move vertically.

[0036] Reference Figure 2 , Figure 3 and Figure 5 The positioning plate 5 is slidably connected to the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the positioning plate 5, allowing the positioning plate 5 to move back and forth. The slider 7 is slidably connected to the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the slider 7, allowing the slider 7 to move left and right. The movable end of the telescopic rod 10 is slidably connected to the top of the positioning plate 5. The bottom end of the telescopic rod 10 has a protrusion. The positioning plate 5 has a slot corresponding to the protrusion, allowing the protrusion to move left and right. The upper side of 10 is provided with an inclined surface, which contacts the inner side wall of the insert 11. The upper part of the insert 11 is provided with a long rod. When the inclined surface presses the long rod, the insert 11 moves upward. The stop block 9 is slidably connected to the inner wall of the worktable 1. The worktable 1 has a slot corresponding to the stop block 9, so that the stop block 9 can move left and right. The insert 11 is inserted into the top of the worktable 1. The lower part of the insert 11 is provided with an inclined surface. The worktable 1 has multiple sets of slots corresponding to the insert 11. When the slots press the inclined surface, the insert 11 moves upward.

[0037] Working principle: Before cutting the board, manually pull the protective plate 16 upward. The groove on the protective plate 16 will press against the inclined surface of the limiting block 14, causing the limiting block 14 to move to the right and press the positioning spring 15. When the protective plate 16 is fully opened, the limiting block 14 coincides with the groove on the protective plate 16. The elastic force of the positioning spring 15 will cause the limiting block 14 to insert into the groove of the protective plate 16, thus limiting the protective plate 16. When the protective plate 16 needs to be retracted, manually move the limiting block 14 to the right. When the limiting block 14 separates from the groove of the protective plate 16, manually move the protective plate 16 back to the initial position. At this time, the limiting block 14 coincides with the groove on the protective plate 16. Manually release the limiting block 14, allowing it to insert into the groove of the protective plate 16, thus limiting the protective plate 16.

[0038] When the sheet material needs to be cut, place it on the flat surface of the workbench 1. When the sheet material contacts the stop block 9, continue to move the sheet material to the left. The sheet material will move the stop block 9 to the left, and the stop block 9 will move the threaded rod 8, the slider 7, and the hinge rod 6 to the left. The other end of the hinge rod 6 will bring the two sets of positioning plates 5 closer together. At this time, the positioning plate 5 will stretch the movable spring 12. At the same time, the positioning plate 5 will move the insert block 11 forward. The slot on the workbench 1 will press the inclined surface of the insert block 11, causing the insert block 11 to move upward and press the movable spring 13. When the stop block 9 moves to the leftmost end of the slot on the workbench 1, the positioning plate 5 completes the fitting and positioning of the sheet material. At the same time, the insert block 11 coincides with the slot on the workbench 1. Under the elastic force of the movable spring 13, the insert block 11 is inserted into the slot of the workbench 1, completing the limiting of the positioning plate 5.

[0039] Next, the externally controlled support 3 moves the cutting machine 4 to cut the plate. The support 3 moves the cutting machine 4 left and right to cut the plate. When the plate is cut, it is manually removed. After the plate is removed, the support 3 moves to the right a certain distance. The support 3 moves the telescopic rod 10 to the right. When the inclined surface on the telescopic rod 10 contacts and presses the long rod on the insert block 11, the insert block 11 moves upward. At this time, under the elastic force of the movable spring 12, the two sets of positioning plates 5 separate from each other. The positioning plates 5 move the hinge rod 6 to the right. The other end of the hinge rod 6 will move the slider 7 and the stop 9 to the initial position. Then, the electric control bracket 3 will move the cutting machine 4 to the initial position. As the inclined surface of the telescopic rod 10 no longer contacts the insert 11, the insert 11 will coincide with the slot on the worktable 1, allowing the insert 11 to be inserted into the slot of the worktable 1, thus limiting the positioning plate 5. When it is necessary to adjust the positioning distance between the two sets of positioning plates 5, the position of the stop 9 can be changed by manually rotating the threaded rod 8. The closer the stop 9 is to the left end of the slot on the worktable 1, the greater the distance between the two sets of positioning plates 5.

Although the present 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.
