Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for testing and preparing road bricks. Background Technology

[0002] As an important building material, the mechanical properties of paving bricks (such as compressive strength and flexural strength) are key indicators for quality testing. Before laboratory testing, the entire paving brick must be cut and ground into standard specimens of specified dimensions according to relevant standards. Currently, this sample preparation process usually relies on operators using traditional stone cutting machines and manual fixing to complete the task.

[0003] However, existing cutting devices lack efficient and dedicated clamping mechanisms. Operators usually need to use auxiliary tools such as clamps and pads to manually clamp the devices, and after cutting, they also need to manually loosen the clamps. The whole process is cumbersome and labor-intensive. Utility Model Content

[0004] In order to overcome the lack of efficient and dedicated clamping mechanisms in existing cutting devices, which mainly rely on operators to manually clamp and release the clamps, resulting in cumbersome operation, this utility model proposes a cutting device for paving brick testing and sample preparation that is convenient to operate and can quickly clamp and release the clamps.

[0005] To achieve the above-mentioned technical objectives, this utility model provides a cutting device for preparing samples for testing paving bricks:

[0006] It includes a base plate and an operating box. The operating box has an opening facing forward, and its left, right, rear, and top walls are all closed structures. The bottom of the operating box is fixed to the base plate. A door for sealing the front opening of the operating box is rotatably connected to the front of the operating box. A cutting machine is installed inside the operating box, and a cylindrical rod is fixed on the cutting machine. The cylindrical rod passes through the operating box and slides inside the operating box. A column is fixed to the top of the cylindrical rod, and connecting rods are rotatably connected to both ends of the column. A first movable plate is installed on the top of the operating box. The ends of the two connecting rods away from the column are rotatably connected to the first movable plate. A groove is opened in the first movable plate, and the cylindrical rod is located in the groove. Two clamping plates are installed inside the operating box. L-shaped rods are installed on both sides of the operating box. The short side of the L-shaped rod passes through the operating box and slides inside the operating box. The short side of the L-shaped rod extends into the operating box and is fixed to the clamping plate.

[0007] Preferably, the top of the control box has two rectangular slots, a rectangular plate is slidably connected in the rectangular slots, a stroke groove is provided in the rectangular plate, and a screw is fixed to the top of the long side of the L-shaped rod, the screw being slidably engaged in the stroke groove.

[0008] Preferably, the screw is threadedly connected to a threaded sleeve on the outside, the diameter of the threaded sleeve and the width of the L-shaped rod are both greater than the width of the stroke groove, and two torque handles are symmetrically fixed on the outside of the threaded sleeve.

[0009] Preferably, connecting plates are fixed on both sides of the first movable plate, and a second movable plate is fixed on the end of the connecting plate away from the first movable plate. The second movable plate has an extrusion groove and a constraint groove, and the extrusion groove and the constraint groove are connected. A protruding post is fixed on the rectangular plate, and the protruding post is slidably fitted in the extrusion groove and the constraint groove.

[0010] Preferably, the operation box is fixed with a second U-shaped limiting plate and two first U-shaped limiting plates, the first movable plate is slidably engaged within the second U-shaped limiting plate, and the second movable plate is slidably engaged within the first U-shaped limiting plate.

[0011] Preferably, an extension plate is fixed to the top of the control box, and the top of the extension plate and the top of the control box are on the same horizontal plane.

[0012] Preferably, one end of the first movable plate is fixed with an L-shaped plate, the L-shaped plate has a circular hole, a handle is slidably connected in the circular hole, and anti-detachment posts are fixed at the top and bottom of the handle, the diameter of the anti-detachment posts being larger than the diameter of the circular hole.

[0013] Preferably, two push handles are fixed on one side of the extension plate, and casters are installed at the four corners of the bottom of the base plate.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1) When the first and second moving plates move toward the cylindrical rod, the clamping plate will automatically clamp and fix the paving brick. When they continue to move, the cutting machine will cut the paving brick. After cutting, when the first and second moving plates move away from the cylindrical rod, the cutting machine will first leave the paving brick, and then the clamping plate will automatically release the paving brick. This process of clamping and releasing the paving brick no longer requires manual operation by the operator, which improves the convenience of operation and increases the efficiency of sample preparation.

[0016] 2) Rotate the handle to make the threaded sleeve rotate, so that the threaded sleeve and the L-shaped rod are no longer pressed against the rectangular plate. Then manually move the two L-shaped rods so that the L-shaped rods drive the clamping plate to move until the clamping plate clamps the paving brick. Then tighten the threaded sleeve so that the threaded sleeve and the L-shaped rod clamp the rectangular plate. This adjustment makes the device suitable for paving bricks of different sizes.

[0024] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] Reference Figure 1-6 :

[0026] In one embodiment of this utility model, a cutting device for preparing samples for testing paving bricks is provided, including a base plate 1 and an operating box 2. The operating box 2 has an opening facing forward, and its left side wall, right side wall, rear side wall, and top wall are all closed structures. The bottom of the operating box 2 is fixed to the base plate 1. A door 3 for sealing the front opening of the operating box 2 is rotatably connected to the front side of the operating box 2. A cutting machine 4 is installed inside the operating box 2, and a cylindrical rod 5 is fixed on the cutting machine 4. The cylindrical rod 5 passes through the operating box 2 and slides inside the operating box 2. 5. A column 6 is fixed at the top. Both ends of the column 6 are rotatably connected to connecting rods 7. A first movable plate 8 is provided at the top of the operation box 2. The ends of the two connecting rods 7 away from the column 6 are rotatably connected to the first movable plate 8. A groove 9 is provided in the first movable plate 8. The cylindrical rod 5 is located in the groove 9. Two clamping plates 11 are provided in the operation box 2. L-shaped rods 10 are provided on both sides of the operation box 2. The short side of the L-shaped rod 10 passes through the operation box 2 and slides inside the operation box 2. After the short side of the L-shaped rod 10 extends into the operation box 2, it is fixed to the clamping plate 11.

[0027] The top of the control box 2 is fixed with an extension plate 24, and the top of the extension plate 24 and the top of the control box 2 are on the same horizontal plane. One end of the first movable plate 8 is fixed with an L-shaped plate 25. A round hole 27 is opened in the L-shaped plate 25. A handle 26 is slidably connected in the round hole 27. Anti-detachment posts 28 are fixed at the top and bottom of the handle 26. The diameter of the anti-detachment posts 28 is larger than the diameter of the round hole 27. Two push handles 31 are fixed on one side of the extension plate 24. Casters 30 are installed at the four corners of the bottom of the base plate 1.

[0028] It should be noted that when the anti-detachment post 28 at the top of the handle 26 is in contact with the top of the L-shaped plate 25, the anti-detachment post 28 at the bottom of the handle 26 can press against the extension plate 24. At this time, the handle 26 acts as a barrier, preventing the cutting machine 4 from sliding down inside the control box 2, thus facilitating the operator to replace the cut paving bricks. However, when the handle 26 is moved upward, so that the anti-detachment post 28 at the bottom of the handle 26 is in contact with the bottom of the L-shaped plate 25, there is a gap between the anti-detachment post 28 at the bottom of the handle 26 and the top of the extension plate 24. At this time, when the handle 26 is held and moved, the extension plate 24 will not obstruct the movement of the anti-detachment post 28 at the bottom of the handle 26.

[0029] In addition, two rectangular slots 12 are provided on the top of the control box 2. A rectangular plate 13 is slidably connected in the rectangular slots 12. A stroke slot 15 is provided in the rectangular plate 13. A screw 14 is fixed to the top of the long side of the L-shaped rod 10. The screw 14 is slidably fitted in the stroke slot 15. A threaded sleeve 16 is threadedly connected to the outside of the screw 14. The diameter of the threaded sleeve 16 and the width of the L-shaped rod 10 are both greater than the width of the stroke slot 15. Two torque handles 29 are symmetrically fixed to the outside of the threaded sleeve 16.

[0030] Furthermore, connecting plates 18 are fixed on both sides of the first movable plate 8, and a second movable plate 19 is fixed on the end of the connecting plate 18 away from the first movable plate 8. The second movable plate 19 has an extrusion groove 20 and a constraint groove 21, and the extrusion groove 20 and the constraint groove 21 are connected. A protruding post 17 is fixed on the rectangular plate 13, and the protruding post 17 is slidably fitted in the extrusion groove 20 and the constraint groove 21. A second U-shaped limiting plate 23 and two first U-shaped limiting plates 22 are fixed on the operation box 2. The first movable plate 8 is slidably fitted in the second U-shaped limiting plate 23, and the second movable plate 19 is slidably fitted in the first U-shaped limiting plate 22.

[0031] In use, place the paving brick to be tested in the operation box 2 for cutting and sample preparation, close the box door 3, then hold the connecting plate 18 with one hand and move it slightly away from the cylindrical rod 5 so that the anti-detachment column 28 at the bottom of the handle 26 is no longer pressed against the extension plate 24. Then hold the anti-detachment column 28 at the top of the handle 26 and move it upward so that the handle 26 moves upward within the L-shaped plate 25. When the anti-detachment column 28 at the bottom of the handle 26 moves to fit against the L-shaped plate 25, hold the handle 26 and move it to push the handle 26 closer to the cylindrical rod 5, thereby driving the first moving plate 8 and the second moving plate 19 to move towards the cylindrical rod 5.

[0032] Furthermore, in some embodiments, when the second moving plate 19 moves, the extrusion groove 20 first extrudes the protrusion 17 and drives the protrusion 17 to move. When the protrusion 17 moves, it drives the rectangular plate 13 to move into the rectangular groove 12. When the rectangular plate 13 moves, it drives the L-shaped rod 10 and the clamping plate 11 to move. At this time, the two clamping plates 11 move closer to each other and clamp the paving brick. After the paving brick is clamped, the protrusion 17 moves from the extrusion groove 20 into the constraint groove 21. At this time, the cutting machine 4 is still some distance away from the paving brick, and then continues to push. When the first moving plate 8 and the second moving plate 19 move, the protruding column 17 will slide in the constraint groove 21, that is, the L-shaped rod 10 and the clamping plate 11 will no longer move. That is, after the road brick is clamped, the clamping plate 11 will no longer move. At this time, the first moving plate 8 will continue to drive the connecting rod 7 to rotate when it moves. When the connecting rod 7 rotates, it will drive the cylindrical rod 5 and the cutting machine 4 to move down, so that the cutting machine 4 gradually moves closer to the road brick. Since the road brick has been clamped and fixed in advance, the cutting machine 4 can then move down to cut it.

[0033] Furthermore, in some embodiments, after the paving brick is cut, the gripping rod 26 is pulled away from the cylindrical rod 5, thereby causing the first moving plate 8 and the second moving plate 19 to move away from the cylindrical rod 5. At this time, the connecting rod 7 rotates, causing the cylindrical rod 5 and the cutting machine 4 to move upward. At this time, the protruding post 17 slides in the constraint groove 21. When the cutting machine 4 moves away from the paving brick, the first moving plate 8 and the second moving plate 19 continue to move. When the protruding post 17 slides from the constraint groove 21 into the extrusion groove 20, the protruding post 17 slides in the extrusion groove 20, so that the protruding post 17 will drive the L-shaped rod 10 and the clamping plate 11 to move away from the operating box 2. That is, the clamping plate 11 can automatically release the paving brick.

[0034] It should be understood that when the first moving plate 8 and the second moving plate 19 move toward the cylindrical rod 5, the clamping plate 11 will automatically clamp and fix the paving brick. When they continue to move, the cutting machine 4 will cut the paving brick. After cutting, when the first moving plate 8 and the second moving plate 19 move away from the cylindrical rod 5, the cutting machine 4 will first leave the paving brick, and then the clamping plate 11 will automatically release the paving brick. This process eliminates the need for manual operation for clamping and fixing the paving brick, improving the convenience of operation and increasing the efficiency of sample preparation.

[0035] It should be noted that when preparing test samples for different batches of paving bricks, adjustments are required due to the different sizes of the paving bricks. During adjustments, the paving brick is first placed in the operating box 2, and then the handle 29 is rotated to rotate the threaded sleeve 16, so that the threaded sleeve 16 and the L-shaped rod 10 are no longer pressed against the rectangular plate 13. Then, one operator holds the handle 26 to move the first moving plate 8 and the second moving plate 19 towards the cylindrical rod 5, causing the protrusion 17 to slide from the extrusion groove 20 into the constraint groove 21. At this time, the movement of the first moving plate 8 will cause the connecting rod 7 to rotate, and the rotation of the connecting rod 7 will cause the cylindrical rod 5 and the cutting machine 4 to move downwards. However, at this time, there is still a gap between the cutting machine 4 and the paving brick. Because the rectangular plate 13 is not... The brick is then clamped by the threaded sleeve 16 and the L-shaped rod 10, with the protruding post 17 located in the constraint groove 21. The two L-shaped rods 10 are then manually moved, causing them to move the clamping plate 11 until the clamping plate 11 clamps the paving brick. The threaded sleeve 16 is then tightened, causing the threaded sleeve 16 and the L-shaped rod 10 to clamp the rectangular plate 13. Since the protruding post 17 is located in the constraint groove 21, when the second moving plate 19 is moved, when the protruding post 17 moves into the constraint groove 21, the two clamping plates 11 can clamp the paving brick. When the protruding post 17 moves from the constraint groove 21 to the extrusion groove 20, the two clamping plates 11 move away from each other and automatically release the paving brick. This adjustment allows the device to be used for paving bricks of different sizes.
