[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 an electric cutting machine for construction engineering, comprising a base 1, with four sets of support columns at the bottom of the base 1 to support the entire device. A worktable 2 is slidably connected to the top of the base 1, and the bottom of the worktable 2 has a slot corresponding to the top of the base 1 to allow the worktable 2 to move laterally. A movable plate 3 is slidably connected to the bottom of the worktable 2, and a fixed column 4 is slidably connected through the inner wall of the movable plate 3. The movable plate 3 has two sets of slots, which are inclined. A pressing plate 5 is fixedly connected to the top of the fixed column 4. Two sets of pressing plates 5 are provided, and the two sets of pressing plates 5 clamp and position the material when they come together. A limit mechanism is provided on the right side wall of the movable plate 3. An electric cutting machine is fixedly connected to the front end of the base 1 via a bracket. The motor 9 is a device or apparatus that converts electrical energy into mechanical energy. Through the interaction of current in a magnetic field, the components inside the motor rotate, thereby generating mechanical motion or driving other mechanical equipment to work. The above is existing technology and will not be elaborated further. The output end of the motor 9 is equipped with a positioning component. The limiting mechanism includes a pull rod 6. A lever 7 is inserted into the outer wall of the pull rod 6. The outer wall of the pull rod 6 is provided with multiple sets of slots, so that the lever 7 can be inserted into the slots of the pull rod 6 to limit the pull rod 6. The front end of the lever 7 is elastically connected to the worktable 2 through a movable spring 8. The lever 7 is provided with an inclined surface. When the pull rod 6 moves to the right, the slots on the pull rod 6 will squeeze the inclined surface of the lever 7, causing the lever 7 to move. The pull rod 6 is fixedly connected to the right side wall of the moving plate 3.
[0034] Reference Figure 4 and Figure 5 The positioning component includes a rotating column 10. A locking block 11 is elastically connected to the inner wall of the top of the rotating column 10 via a moving spring 12. The locking block 11 has a flat front end and a beveled end, with the beveled end higher than the flat end. When the blade 13 is installed, the beveled end of the locking block 11 is compressed, causing it to move downwards. After installation, the flat end is inserted into the slot of the blade 13, and the beveled end provides blocking and limiting for the blade 13. The blade 13 is detachably mounted on the outer wall of the rotating column 10. A rectangular block is provided on the rotating column 10 to allow the blade 13 to rotate in a fixed position. The blade 13 is made of metal and can quickly and accurately cut metal. Materials and improved construction efficiency are existing technologies and will not be elaborated further. The front end of the rotating column 10 is fixedly connected to the output end of the motor 9. The locking block 11 is inserted into the outer wall of the blade 13 and slidably connected to the inner wall of the rotating column 10. The inner wall of the rotating column 10 has a slot corresponding to the locking block 11 to ensure that the locking block 11 can move vertically. The top inner wall of the rotating column 10 is fixedly connected to one end of the moving spring 12, and the other end of the moving spring 12 is fixedly connected to the bottom end of the locking block 11. When the locking block 11 moves downward, the moving spring 12 is compressed. When resetting, the elastic force of the moving spring 12 is used to reset the locking block 11.
[0035] Reference Figures 1-3 The fixed column 4 is slidably connected to the inner wall of the worktable 2. The worktable 2 has a transverse opening so that the fixed column 4 can move laterally. The bottom end of the pressing plate 5 is in contact with the top end of the worktable 2. The lever 7 is slidably connected to the right side wall of the worktable 2. The right side wall of the worktable 2 has a slot corresponding to the lever 7 so that the lever 7 can move back and forth. The pull rod 6 is slidably connected to the inner wall of the worktable 2. The right side wall of the worktable 2 has a slot corresponding to the pull rod 6 so that the pull rod 6 can move left and right. The front end of the lever 7 is fixedly connected to one end of the movable spring 8. The other end of the movable spring 8 is fixedly connected to the front inner wall of the worktable 2. When the lever 7 moves forward, the movable spring 8 is compressed. When resetting, the elastic force of the movable spring 8 is used to reset the lever 7.
[0036] Working principle: When material cutting is required, place the material on the workbench 2, then pull the lever 6 to the right. The lever 6 will move the moving plate 3 to the right. As the moving plate 3 moves to the right, the groove on the moving plate 3 will press the two sets of fixed posts 4 together. The two sets of fixed posts 4 will then press the two sets of pressing plates 5 together, clamping and positioning the material. At the same time, as the lever 6 moves to the right, the groove on the lever 6 will press the inclined surface of the lever 7, causing the lever 7 to move forward. Move and disengage from the slot on the pull rod 6. The moving block 7 will compress the movable spring 8 as it moves forward. When the pressing plate 5 clamps and positions the material, the moving block 7 will overlap with the slot on the pull rod 6. Using the elastic force of the movable spring 8, the moving block 7 will be inserted into the slot on the pull rod 6, thus limiting the pressing plate 5. Then, the motor 9 can be turned on to drive the rotating column 10 and the blade 13 to rotate, pushing the worktable 2 towards the blade 13, allowing the high-speed rotating blade 13 to cut the material.
[0037] When the material size is large and the position of the two sets of pressing plates 5 needs to be expanded, simply pull the lever 7 forward. The forward movement of the lever 7 will compress the movable spring 8. After the lever 7 disengages from the slot on the pull rod 6, push the pull rod 6 to the left. The pull rod 6 will move the moving plate 3 to the left. When the moving plate 3 moves to the left, the slot on the moving plate 3 will compress the two sets of fixing posts 4 to separate from each other. The two sets of fixing posts 4 will then separate the two sets of pressing plates 5 from each other, expanding the distance between the two sets of pressing plates 5. At this time, the first operation can be repeated to complete the clamping and positioning of the material.
[0038] When the blade 13 is severely worn and needs to be replaced, press the locking block 11 with your hand. The locking block 11 will move downward and compress the moving spring 12. When the locking block 11 moves downward and no longer obstructs or limits the blade 13, move your hand backward to remove the blade 13. After the blade 13 is removed, release the locking block 11. Use the elastic force of the moving spring 12 to reset the locking block 11. At this time, align the new blade 13 with the rotating column 10 and push the blade 13 forward. When the blade 13 contacts the inclined surface of the locking block 11, the blade 13 will compress the inclined surface of the locking block 11, allowing the locking block 11 to move downward and fully enter the rotating column 10. The downward movement of the locking block 11 will compress the moving spring 12. When the blade 13 moves to the initial position, the locking block 11 is no longer obstructed. Use the elastic force of the moving spring 12 to reset the locking block 11, thus completing the obstruction and limitation of the blade 13. If you need to replace the blade 13 again, simply repeat the above steps.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
