Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of engraving machines, and in particular relates to a concrete engraving machine. Background Art
[0002] Concrete carving is a process of giving concrete materials an artistic or decorative appearance through carving techniques. This process can be applied to a variety of construction and decoration projects to enhance the beauty and personalization of buildings. At present, the commonly used concrete material is cement pressure board, also known as cement fiberboard or cement particleboard, which is a building material made by mixing and pressing cement, wood fiber and other additives. Cement pressure board has high mechanical strength and hardness, which allows it to maintain its shape and resist damage during the carving process. This strength also enables the final carving work to withstand the wear and impact of daily use. The thickness of conventional cement pressure board is generally 4-12mm. Although cement pressure board has high strength, it is thin and relatively light, which is easy to carry and install, which is an important advantage in decorative applications.
[0003] When cement pressure plates are engraved, a lot of concrete residue will be generated. If the concrete residue accumulates in the engraving area, it will accelerate the wear of the tool, reduce work efficiency, affect the engraving quality, and may even cause damage to the tool. Because the concrete residue particles are large, it is difficult for existing air blowing equipment to blow the residue out of the grooves of the engraved pattern under normal pressure. If the air pressure is increased, the direction and distance of the concrete residue are difficult to control, which is easy to cause harm to surrounding workers.
[0004] In view of the above problems, a concrete engraving machine which is convenient for cleaning concrete residues is designed. Summary of the invention
[0005] The purpose of the invention is to provide a concrete engraving machine which is convenient for cleaning concrete residues.
[0006] The present invention is realized through the following measures: a concrete engraving machine comprises a workbench, a mounting frame is arranged across the top of the workbench, a movable frame which reciprocates along the X-axis direction is arranged on the mounting frame, a drill unit which reciprocates along the Z-axis direction is arranged on the movable frame, and the characteristic is that a lead screw 1 arranged along the Y-axis direction is rotatably arranged at the middle position below the workbench, a lead screw nut is arranged on the lead screw 1 through a threaded connection, and movable plates extending out of the workbench are symmetrically arranged on both sides of the lead screw nut, and vertical plate structures are fixedly arranged at the outer ends of the two movable plates, and the two ends of the mounting frame are fixedly arranged on the vertical plate structure, and guide blocks are fixedly arranged on the inner sides of the vertical plate structure, and guide rods are fixedly arranged on the outer wall of the workbench, and guide grooves cooperating with the guide rods are arranged on the guide blocks; A guide boss is symmetrically arranged on one side of the table top of the workbench, a slider sliding along the X-axis direction is arranged on the guide boss, the upper ends of the two sliders extend out of the guide boss and a support plate is rotatably arranged on the extended end, a hydraulic rod is arranged on the table top and on the inner side of the guide boss, and the push rod of the hydraulic rod is connected to the slider; a fixed plate is symmetrically arranged on the other side of the table top, the fixed plate and the support plate are connected by a connecting rod, the inner end of the connecting rod is hinged on the support plate, and the outer end of the connecting rod is hinged on the fixed plate; When the connecting rod is parallel to the table, the support plate is parallel to the table; when the hydraulic rod drives the slider to move toward the connecting rod along the X-axis direction, the inner end of the connecting rod rotates upward to drive the support plate to rise; Vertical baffles are symmetrically arranged on both sides of the support plate, and external plates parallel to the table top are fixedly arranged on the outer sides of the upper ends of the vertical baffles, and clamps are arranged on the external plates, and a plurality of clamps are arranged at intervals along the Y-axis direction; the clamps adopt the existing technology, and the specific structure is not repeated here; The external plate is provided with an air pipe arranged along the Y-axis direction, the air pipe is provided with a plurality of nozzles facing the vertical baffle, and either end of the air pipe is connected to an air pump through a hose.
[0007] The guide boss comprises two symmetrically arranged vertical plates and a connecting plate connecting the upper ends of the two vertical plates, the connecting plate is provided with a long strip opening, the slider is slidably arranged in the long strip opening, and the inner side of the upper end of the slider is rotatably connected to the support plate through a hinge shaft 1; An ear plate hinged to the slider and the connecting rod is provided below the support plate. When the support plate is parallel to the table top, the lower end surface of the ear plate connected to the slider contacts the table top. This can improve the support strength of the support plate in a horizontal state.
[0008] Either end of the lead screw 1 is connected to a motor 1 with a reducer, and the motor 1 is fixed on the outer wall of the workbench.
[0009] Directions: The cement pressure plate to be engraved is placed on the support plate, and then the cement pressure plate is fixed by a clamp. When the concrete residue on the cement pressure plate needs to be cleaned, the hydraulic rod is started, and the hydraulic rod drives the slider to move in the direction of the hydraulic rod, and one end of the support plate connected to the slider moves along with it. During the movement, the connecting rod rotates and drives one end of the support plate connected thereto to tilt upward, and the support plate is in an inclined state at this time. At this time, the staff can use a broom to clean the concrete residue. Since the support plate is in an inclined state, it is easy to remove the residue on the surface of the cement pressure plate or in the engraving groove. In addition, the air pump can also be started to clean the concrete residue with high-pressure gas. Since the support plate is in an inclined state, the residue can be cleaned with a relatively small air pressure.
[0010] Side baffles are provided on the outer edges of the table top and on the outer sides of the support plate; When the support plate is parallel to the table top, the upper end surface of the side baffle is slightly lower than the upper end surface of the support plate, so that the cement pressure plate can be conveniently placed on the support plate.
[0011] The upper end surfaces of the vertical baffle plate and the external connecting plate are lower than the upper end surface of the cement pressure plate, which makes it convenient to clean up the residue later.
[0012] A plurality of support plates are arranged below the table top of the workbench, and a plurality of strip openings are opened on one side of the table top where the guide boss is arranged. Concrete residues on the cement pressure plate can fall onto the ground through the strip openings, and containers corresponding to the strip openings can be placed on the ground for easy recycling. Concrete residues can fall directly into the container for easy recycling.
[0013] The mounting frame includes a mounting plate connecting the two vertical plate structures, a second lead screw is rotatably arranged between the two vertical plate structures, the moving frame is arranged on the second lead screw by threaded connection, two guide rails are symmetrically arranged on the mounting plate, and a guide rail groove matching the guide rail is arranged on the moving frame; One end of the second lead screw close to the fixed plate extends out of the vertical plate structure, and the extended end is connected to the second motor with a reducer.
[0014] The lower outer side of the vertical plate structure is rotatably provided with a rotating shaft 1, a rotating shaft 2 and a rotating shaft 3, the rotating shaft 1 is connected to the motor shaft of the motor 2 by a transmission belt, the rotating shaft 1 is provided with a driving gear, the rotating shaft 2 is provided with a driven gear meshing with the driving gear, the rotating shaft 3 is provided with a local gear meshing with the driven gear, the inner end of the rotating shaft 3 extends into the vertical plate structure and a screw is fixedly provided at the extending end, a limiting column is provided on the screw through a threaded connection, and a guide plate is symmetrically provided on the vertical plate structure and located on the outer side of the limiting column; the local gear can be a quarter.
[0015] An extension plate is fixedly provided on the outer edge of the table plate and located on the outer side of the vertical baffle, and the extension plate is parallel to the external connecting plate; When the support plate is parallel to the table top, the limiting column can extend between the extension plate and the external plate; The transmission from the motor shaft of the motor 2 to the rotating shaft 1 and the transmission from the rotating shaft 1 to the rotating shaft 2 both adopt reduction transmission; When the lead screw rotates to drive the movable frame to move in a direction away from the motor, the screw rod rotates at the same time to drive the limiting column to gradually leave the space between the extension plate and the external plate.
[0016] By adopting a reduction transmission, the limit column can be completely separated from the space between the extension plate and the external plate only when the mobile frame is far away from the motor 2, so as to achieve the limit of the support plate. Because the end of the support plate close to the motor 2 is an upturned end, and since a drill unit is provided on the mobile frame, the presence of the drill unit will affect the upturned height of the support plate, and at the same time, it can prevent the support plate from hitting the drill bit during the upturning process. For safety reasons and the limitations of the mounting frame, the maximum inclination angle of the support plate is generally less than 30 degrees, preferably about 15 degrees.
[0017] The inner end of the limit column is transitioned through a rounded corner or a chamfered corner, so that it is convenient to enter the space between the extension plate and the external plate.
[0018] The drill unit includes a lead screw three rotatably arranged on the mobile frame, a motor frame is arranged on the lead screw three through a threaded connection, the drill motor is installed on the motor frame, guide rods are symmetrically arranged on the mobile frame, and guide holes matching the guide rods are arranged on the motor frame. The upper end of the lead screw three extends out of the bracket and is connected to the motor three with a reducer.
[0019] In addition, without affecting the normal movement of the moving frame, the side baffle close to the guide boss can be appropriately extended upward.
[0020] The vertical plate structure adopts two vertical plates connected by a plurality of support columns, a boss is arranged in the middle of the support column, and the two vertical plates are sleeved on the support column and fixed by nuts.
[0021] Working principle: In the initial position, the support plate is parallel to the table surface, and the cement pressure plate to be engraved is placed on the support plate, and then the cement pressure plate is fixed by a clamp. When engraving the cement pressure plate, the moving frame generally moves in the middle area of the cement pressure plate. Although the screw rotates, the limit column does not completely leave the space between the extension plate and the external plate (which can be achieved according to the transmission ratio between the motor shaft 2, the rotating shaft 1, the rotating shaft 2 and the rotating shaft 3). When the limit column does not completely leave the space between the extension plate and the external plate, even if the hydraulic rod is activated, the support plate cannot be lifted.
[0022] When it is necessary to clean the concrete residue on the cement pressure plate, start motor 1, so that the lead screw 1 rotates and drives the movable frame to approach motor 2, when the limit column completely leaves the space between the extension plate and the external plate. Start the hydraulic rod, and the hydraulic rod drives the slider to move in the direction of the hydraulic rod. One end of the support plate connected to the slider moves along with it. During the movement, the connecting rod rotates and drives one end of the support plate connected thereto to tilt upward. At this time, the support plate is in an inclined state. At this time, the staff can use a broom to clean the concrete residue. Since the support plate is in an inclined state, it is easy to remove the residue on the surface of the cement pressure plate or in the engraved groove. In addition, the air pump can also be started to clean the concrete residue with high-pressure gas. Since the support plate is in an inclined state, the residue can be cleaned with a relatively small air pressure.
[0023] The beneficial effects of the technical solution provided by the embodiment of the present invention are: when cleaning the concrete residue on the cement pressure plate, the support plate can be automatically lifted to assist manual cleaning of the concrete residue on the cement pressure plate; in order to facilitate cleaning, a gas nozzle is provided at a high position where the support plate is lifted; in order to prevent the drill bit from being at the upturned end of the support plate when the support plate is lifted, thereby causing damage to the drill bit, a screw rod linked to the lead screw 1 is provided, and the simultaneous movement of the lead screw 1 and the screw rod 1 is achieved through the reduction transmission, which can not only realize the movement of the movable frame but also realize the limiting of the support plate by the limiting column at the same time.

The upper ends of the two sliders 16 extend out of the guide boss 15 and the extended ends are rotatably provided with a support plate 2. A hydraulic rod 17 is arranged on the table 10301 and located on the inner side of the guide boss 15. The push rod 1701 of the hydraulic rod 17 is connected to the slider 16. A fixed plate 10301 is symmetrically arranged on the other side of the table 10301. The fixed plate 10301 is connected to the support plate 2 through a connecting rod 18. The inner end of the connecting rod 18 is hinged on the support plate 2, and the outer end of the connecting rod 18 is hinged on the fixed plate 10301. When the connecting rod 18 is parallel to the table 10301, the support plate 2 is parallel to the table 10301; when the hydraulic rod 17 drives the slider 16 to move toward the connecting rod 18 along the X-axis direction, the inner end of the connecting rod 18 rotates upward to drive the support plate 2 to tilt upward; Vertical baffles 201 are symmetrically arranged on both sides of the support plate 2.

[0029] The guide boss 15 includes two symmetrically arranged vertical plates 1501 and a connecting plate 1502 connecting the upper ends of the two vertical plates 1501. The connecting plate 1502 is provided with a long strip opening 1503. The slider 16 is slidably arranged in the long strip opening 1503.

An ear plate 204 is provided below the support plate 2 and is hinged to the slider 16 and the connecting rod 18. When the support plate 2 is parallel to the table 10301, the lower end surface of the ear plate 204 connected to the slider 16 contacts the table 10301.

[0030] Either end of the lead screw 9 is connected to a motor 901 with a reducer, and the motor 901 is fixed on the outer wall of the workbench 1.
[0031] Directions: The cement pressure plate to be engraved is placed on the support plate 2, and then the cement pressure plate is fixed by the clamping fixture 7. When the concrete residue on the cement pressure plate needs to be cleaned, the hydraulic rod 17 is started, and the hydraulic rod 17 drives the slider 16 to move in the direction of the hydraulic rod 17, and one end of the support plate 2 connected to the slider 16 moves along with it. During the movement, the connecting rod 18 rotates and drives one end of the support plate 2 connected thereto to tilt upward, and the support plate 2 is in an inclined state. At this time, the staff can clean the concrete residue with a broom. Since the support plate 2 is in an inclined state, it is easy to remove the residue on the surface of the cement pressure plate or in the engraving groove. In addition, the air pump can also be started to clean the concrete residue with high-pressure gas. Since the support plate 2 is in an inclined state, the residue can be cleaned by using a relatively small air pressure.
[0032] Side baffles are provided around the outer edges of the tabletop 10301 and on the outer side of the support plate 2; When the support plate 2 is parallel to the table top 10301, the upper end surface of the side baffle is slightly lower than the upper end surface of the support plate 2. This makes it convenient to place a cement pressure plate on the support plate 2.
[0033] The upper end surfaces of the vertical baffle plate 201 and the external plate 202 are lower than the upper end surface of the cement pressure plate, which makes it easier to clean up the residue later.
[0034] A plurality of support plates 102 are arranged below the table 103 of the workbench 1, and a plurality of strip openings 19 are opened on one side of the table 103 where the guide boss 15 is arranged. Concrete residues on the cement pressure plate can fall to the ground through the strip openings 19, and for the convenience of recycling, containers corresponding to the strip openings 19 can be placed on the ground. Concrete residues can fall directly into the container, which is convenient for recycling.
[0035] The mounting frame 3 includes a mounting plate connected to two vertical plate structures 4, a second lead screw 301 is rotatably arranged between the two vertical plate structures 4, a moving frame 5 is arranged on the second lead screw 301 through a threaded connection, two guide rails 302 are symmetrically arranged on the mounting plate, and a guide rail 302 groove matching the guide rail 302 is arranged on the moving frame 5; One end of the lead screw 2 301 close to the fixed plate 10301 extends out of the vertical plate structure 4 and the extended end is connected to the motor 2 303 with a reducer.
[0036] A rotating shaft 10, a rotating shaft 2 12 and a rotating shaft 3 13 are rotatably arranged on the outer lower part of the vertical plate structure 4. The rotating shaft 10 is connected to the motor shaft of the motor 2 303 by a transmission belt 11. A driving gear 1001 is arranged on the rotating shaft 10, a driven gear 1201 meshing with the driving gear 1001 is arranged on the rotating shaft 2 12, and a local gear 1301 meshing with the driven gear 1201 is arranged on the rotating shaft 3 13. The inner end of the rotating shaft 3 13 extends into the vertical plate structure 4 and a screw 1302 is fixedly arranged on the extending end. A limiting column 1303 is arranged on the screw 1302 through a threaded connection. A guide plate 402 is symmetrically arranged on the vertical plate structure 4 and located on the outer side of the limiting column 1303; the local gear 1301 can be a quarter.
[0037] An extension plate 203 is fixedly disposed on the outer edge of the table 103 and located outside the vertical baffle 201 , and the extension plate 203 is parallel to the external plate 202 ; When the support plate 2 and the table 10301 are parallel, the limiting column 1303 can extend between the extension plate 203 and the external plate 202; The transmission from the motor shaft of the motor 2 303 to the rotating shaft 10 and the transmission from the rotating shaft 10 to the rotating shaft 2 12 both adopt reduction transmission; When the lead screw 1 9 rotates to drive the moving frame 5 to move away from the motor 2 303 , the screw rod 1302 rotates at the same time to drive the limiting column 1303 to gradually leave the space between the extension plate 203 and the external plate 202 .
[0038] By adopting the reduction transmission, the limiting column 1303 can be completely separated from the space between the extension plate 203 and the external plate 202 only when the moving frame 5 is far away from the motor 2 303, so as to achieve the limiting of the support plate 2. Because the end of the support plate 2 close to the motor 2 303 is the upturned end, and since the moving frame 5 is provided with a drill unit, the existence of the drill unit will affect the upturned height of the support plate 2, and at the same time, it can prevent the support plate 2 from damaging the drill 602 during the upturning process. For safety reasons and the limitation of the mounting frame 3, the maximum inclination angle of the support plate 2 is generally less than 30 degrees, preferably about 15 degrees.
[0039] The inner end of the limiting column 1303 is transitioned through a rounded corner or a chamfered corner, so that it is convenient to enter the space between the extension plate 203 and the external plate 202.

[0042] The vertical plate structure 4 is formed by connecting two vertical plates through a plurality of support columns. A boss is arranged in the middle of the support column. The two vertical plates are sleeved on the support column and fixed by nuts.
[0043] Working principle: In the initial position, the support plate 2 is parallel to the table 10301, and the cement pressure plate to be engraved is placed on the support plate 2, and then the cement pressure plate is fixed by the clamping clamp 7. When the cement pressure plate is engraved, the moving frame 5 generally moves in the middle area of the cement pressure plate. Although the screw 1302 rotates, the limit column 1303 does not completely leave the space between the extension plate 203 and the external plate 202 (which can be achieved according to the transmission ratio between the motor shaft 2, the rotating shaft 10, the rotating shaft 2 12 and the rotating shaft 3 13). When the limit column 1303 does not completely leave the space between the extension plate 203 and the external plate 202, even if the hydraulic rod 17 is started, the support plate 2 cannot be lifted.
[0044] When it is necessary to clean the concrete residue on the cement pressure plate, start the motor 1 901, so that the screw 1 9 rotates and drives the mobile frame 5 to approach the motor 2 303, when the limit column 1303 completely leaves the space between the extension plate 203 and the external plate 202. Start the hydraulic rod 17, the hydraulic rod 17 drives the slider 16 to move in the direction of the hydraulic rod 17, and the end of the support plate 2 connected to the slider 16 moves along. During the movement, the connecting rod 18 rotates and drives the end of the support plate 2 connected thereto to tilt upward, and the support plate 2 is in an inclined state. At this time, the staff can use a broom to clean the concrete residue. Since the support plate 2 is in an inclined state, it is easy to remove the residue on the surface of the cement pressure plate or in the engraved groove. In addition, the air pump can also be started to clean the concrete residue by high-pressure gas. Since the support plate 2 is in an inclined state, the residue can be cleaned by using a relatively small air pressure.
