Description

Technical Field

[0001] This utility model belongs to the field of brick cutting technology, and in particular relates to a high-precision mechanical cutting table structure for brick cutting. Background Technology

[0002] Bricks are common building materials, typically made from raw materials such as clay, shale, coal gangue, and fly ash, through processes including molding, drying, and firing. In architectural design, standard bricks need to be cut into appropriate sizes to achieve specific architectural styles, spatial layouts, or structural requirements.

[0003] Patent CN220313793U discloses a brick cutting device, including a cutting protective cover and a hand-operated cutting machine body. The cutting protective cover is fixed to the outer front end of the hand-operated cutting machine body, and a dust-collecting base is provided at the lower end of the hand-operated cutting machine body. Although the above patent can collect dust generated during the cutting process by setting a dust-collecting base structure, in actual cutting, the cutting position of the brick depends entirely on manual adjustment. Manual adjustment lacks a precise positioning benchmark, making it difficult to guarantee the accuracy of the cutting position each time. Once the cutting position deviates, it will directly affect the dimensional accuracy of the brick. Moreover, using a hand-operated cutting machine for brick cutting relies on manual pressure to drive the machine. This operating mode is extremely physically demanding for the operator. Prolonged high-intensity work can easily cause operator fatigue and increase the risk of uncontrolled cutting force, affecting the cutting quality.

[0004] Therefore, a high-precision mechanical cutting table structure for brick cutting is particularly needed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing patented brick cutting methods, such as the reliance on manual cutting position, lack of precise reference leading to poor dimensional accuracy, and the reliance on manual operation of hand-operated cutting machines, which can easily cause operator fatigue, loss of cutting force control, and affect cutting quality, this utility model provides a high-precision mechanical cutting table structure for brick cutting.

[0006] This utility model is achieved through the following technical means: a high-precision mechanical cutting table structure for brick cutting, including a support table, a first motor, a lead screw, a first guide rod, a slider, a second motor, a pulley set, a transmission shaft, and a cutting blade. The first motor is installed on the upper front side of the support table, with its output shaft facing rearward. One end of the lead screw is fixed to the output shaft of the first motor through a coupling, and the other end is rotatably engaged with the rear of the support table. Two first guide rods are arranged side by side and fixed to the upper part of the support table, respectively located on both sides of the lead screw, with all three having the same length. The slider is threaded on the outside of the lead screw, and its two parts are slidably connected to the two first guide rods respectively. The second motor is installed on the upper left side of the slider, with its output shaft facing left. The transmission shaft is rotatably located on the lower left side of the slider. The pulley set is located between the output shaft of the second motor and one end of the transmission shaft. The cutting blade is fixed to the other end of the transmission shaft. It also includes a clamping and positioning assembly, which is set on the support table.

[0007] Optionally, the clamping and positioning assembly includes a hinge block, a hinge plate, a sliding plate, an extension plate, a pusher, a mounting plate, a second guide rod, a spring, a clamping block, and a ruler. Two hinge blocks are arranged side by side and fixed to the lower right side of the support platform. Each hinge plate is rotatably mounted on each hinge block. Each extension plate is slidably mounted on each hinge plate. The sliding plate is slidably mounted between the two extension plates. The pusher is fixed to the top of the sliding plate. The mounting plate is fixed to the left side of the sliding plate. Two second guide rods are arranged side by side and slidably mounted on the upper part of the mounting plate. The outer diameter of one end of each second guide rod is larger than the outer diameter of its main body. Each clamping block is fixed to the other end of each second guide rod, and its bottom surface forms a sliding contact with the mounting plate. Each spring is sleeved on the outside of each second guide rod, and its two ends are fixedly connected to the clamping block and the mounting plate, respectively. Each ruler is embedded in the upper part of each hinge plate.

[0008] Optionally, each clamp has a ramp at its top that slopes upward from the outside to downward from the inside, and this ramp has a guiding function.

[0009] Optionally, it also includes casters and fixed feet, with multiple fixed feet distributed along a rectangular direction and installed at the bottom of the support platform. Each caster is threaded onto each fixed foot, and its lowest point is higher than the lowest point of the fixed foot.

[0010] Optionally, it also includes a protective cover, which is fixed to the lower part of the slider and located above the cutting blade to block it, and the protective cover is made of high-strength metal.

[0011] Optionally, it also includes a handle, the handle of which is telescopically mounted at the rear of the support platform and has a pull ring structure at its upper end.

[0012] Beneficial effects: 1. The clamping and positioning components automatically clamp the bricks using the clamping blocks and springs, and provide the operator with a position reference using a ruler. This allows the operator to accurately adjust the moving distance of the mounting plate according to the ruler's scale, keeping the perpendicularity error between the brick cutting position and the cutting line within a very small range. This ensures that the brick cutting position and the cutting line of the cutting blade are always on the same vertical plane, improving the brick cutting accuracy and reducing cutting errors.

[0013] An automated cutting execution mechanism consisting of a first motor, lead screw, first guide rod, slider, second motor, pulley set, transmission shaft and cutting blade is used to automate the entire process of cutting blade movement and rotation without manual intervention, thereby reducing labor intensity and human error and comprehensively improving the quality of brick cutting.

[0014] 2. Through the combined action of casters and fixed feet, a seamless switch between flexible movement and stable operation of the equipment can be achieved when needed. Attached Figure Description

[0020] Example: A high-precision mechanical cutting table structure for brick cutting, such as... Figures 1-4As shown, the system includes a support platform 1, casters 101, fixed feet 102, a first motor 2, a lead screw 3, a first guide rod 4, a slider 5, a second motor 6, a pulley set 7, a drive shaft 8, a cutting blade 9, a protective cover 91, and a handle 19. The four fixed feet 102 are distributed along a rectangular axis and bolted to the bottom of the support platform 1. Each caster 101 is threaded onto each fixed foot 102, with its lowest point higher than the lowest point of the fixed foot 102. This ensures that in the initial static state, the fixed feet 102 preferentially contact the ground, providing support. The support platform 1 provides stable support, ensuring its stable parking. When it is necessary to move the support platform 1, simply rotate the caster 101 downwards until the lowest point of the caster 101 is lower than the lowest point of the fixed foot 102. At this time, the caster 101 will provide support, allowing the fixed foot 102 to lift off the ground, thus enabling the support platform 1 to move flexibly. The first motor 2 is bolted to the upper front side of the support platform 1, with its output shaft facing rearward. The front end of the lead screw 3 is fixedly connected to the output shaft of the first motor 2 via a coupling, while the rear end rotates with the rear of the support platform 1. To ensure the smooth rotation of the lead screw 3, two first guide rods 4 are welded side-by-side to the upper part of the support platform 1, located on the left and right sides of the lead screw 3 respectively, with all three maintaining the same length. The slider 5 is threaded onto the outside of the lead screw 3, with its left and right parts slidably connected to the two first guide rods 4 respectively. The second motor 6 is bolted to the upper left side of the slider 5, with its output shaft facing left. The transmission shaft 8 is rotatably positioned on the lower left side of the slider 5. The pulley set 7 is located between the output shaft of the second motor 6 and the left end of the transmission shaft 8. The cutting blade 9 is connected via a keyway. The protective cover 91 is welded to the lower part of the slider 5 and located above the cutting blade 9 to block it. The protective cover 91 is made of high-strength metal and can effectively withstand the impact of the splatter generated during the cutting process. The telescopic handle 19 is rotatably set at the rear of the support platform 1. Its upper end is equipped with a pull ring structure. The handle 19 provides the operator with a clear point of force on the support platform 1, which is convenient for moving the support platform 1. It also includes a clamping and positioning component, which is set on the support platform 1.

[0021] like Figure 1 , Figure 3 and Figure 4As shown, the clamping and positioning assembly includes a hinge block 10, a hinge plate 11, a sliding plate 12, an extension plate 121, a pusher 13, a mounting plate 14, second guide rods 15, a spring 16, a clamping block 17, and a ruler 18. Two hinge blocks 10 are arranged side by side and welded to the lower right side of the support platform 1. Each hinge plate 11 is rotatably mounted on each hinge block 10, and each extension plate 121 is slidably mounted on each hinge plate 11. The sliding plate 12 is slidably mounted between the two extension plates 121. With this connection method, the hinge plate 11 can be rotated to retract against the moving platform when needed. During the rotation of the hinge plate 11, the extension plate 121 is pulled out from inside the sliding plate 12, allowing the hinge plate 11 to rotate smoothly. The pusher 13 is welded to the top of the sliding plate 12, and the mounting plate 14 is welded to the left side of the sliding plate 12. Two second guide rods 15 are arranged side by side and slidably mounted on the upper part of the mounting plate 14. Each second guide rod 15 has an outer diameter at its outer end that is larger than the outer diameter of its main body. This allows the second guide rod 15 to be restricted to the mounting plate 14 by means of the limiting feature formed by the increased outer diameter. Each clamping block 17 is welded to the inner end of each second guide rod 15, and its bottom surface forms a sliding contact with the mounting plate 14. Each clamping block 17 has a slope at its top that slopes from the outside upwards to the inside downwards. This slope has a guiding function. When the brick contacts the clamping block 17, the relative force between the bottom of the brick and the slope can generate a squeezing force that causes the clamping block 17 to move horizontally, thereby causing the clamping block 17 to move along a preset trajectory. Each spring 16 is sleeved on the outside of each second guide rod 15, and its inner and outer ends are fixedly connected to the clamping block 17 and the mounting plate 14, respectively. The spring 16 is a high-strength spring. Each ruler 18 is bolted to the upper part of each hinge plate 11 in an embedded form.

[0022] When brick cutting is required, the operator first places the brick to be cut between the two clamping blocks 17 from top to bottom. As the brick descends, its bottom first contacts the inclined surface at the top of the two clamping blocks 17, and the inclined surface squeezes the two clamping blocks 17 away from each other in the horizontal direction. The spring 16 is then compressed to store energy. When the brick is fully inserted and its bottom contacts the mounting plate 14, the spring 16 begins to release the stored energy under its own elastic force, applying an inward pressure to the two clamping blocks 17. This pressure is evenly applied to both sides of the brick, causing the two clamping blocks 17 to fit tightly against the surface of the brick, firmly clamping the brick and preventing the brick from shifting during the subsequent cutting process.

[0023] After clamping, the position of the brick is adjusted by pulling the mounting plate 14 left and right with the pusher 13. While pulling the mounting plate 14, pay attention to the ruler 18 at all times, and control the moving distance of the mounting plate 14 precisely according to the changes in the value on the ruler 18, so as to ensure that the cutting position of the brick and the cutting line of the cutting blade 9 are precisely kept on the same vertical plane, laying the foundation for high-precision cutting.

[0024] After adjustment, start the second motor 6. Its output shaft drives the transmission shaft 8 to rotate through the pulley group 7. The transmission shaft 8 drives the cutting blade 9 to rotate together. At the same time, start the first motor 2. Its output shaft drives the lead screw 3 to rotate clockwise. Driven by the lead screw 3, the slider 5 moves the cutting blade 9 backward along the lead screw 3 and the first guide rod 4. As the slider 5 drives the cutting blade 9 to gradually approach the brick, the rotating cutting blade 9 contacts the brick. Under the action of cutting force, the brick is gradually cut. During the cutting process, closely observe the cutting situation to ensure that the cutting process is stable and smooth.

[0025] Once the cutting disc 9 has moved to the appropriate position and completely detached from the brick, completing the cutting operation, the second motor 6 is turned off, causing the cutting disc 9 to stop rotating. Then, the output shaft of the first motor 2 is controlled to drive the lead screw 3 to rotate counterclockwise. Driven by the lead screw 3, the slider 5 moves the cutting disc 9 forward, gradually returning it to its initial position, preparing it for the next cutting operation.

[0026] Finally, the second guide rod 15 pulls the two clamping blocks 17 away from each other, releasing the clamping force on the brick. At this time, the cut brick is taken out from between the two clamping blocks 17, completing the entire brick cutting operation process.
