Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and more specifically to a multi-functional chisel surface machine. Background Technology

[0002] Stone chiseling is an important technique in architectural decoration and landscape design. It involves creating regular patterns (i.e., chiseled lines) on the surface, facade, or sides of stones such as granite, marble, bluestone, and sandstone to enhance the stone's decorative appeal and texture. This technique is widely used in walls, floors, sculptures, and other applications. Currently, the tools and equipment used for this type of processing are mostly manual aids; the core processing actions still rely on manual operation.

[0003] However, stone chiseling mainly relies on manual labor using hand-held chisels and hammers to create patterns one by one, which has obvious drawbacks: First, labor costs are high, requiring skilled workers to work continuously, and the labor intensity is high; second, efficiency is extremely low, as processing a single slab takes a long time, making it difficult to meet the needs of mass production; third, processing precision is poor, as the force and frequency of manual hammering are uneven, resulting in low consistency of patterns; and fourth, there is a technical gap, with a serious aging of veteran stonemasons, low willingness among young people to enter the industry, and a growing shortage of skilled workers.

[0004] Therefore, there is an urgent need to design a multi-functional chisel surface machine that can automate processing, adapt to flat and curved plates, achieve high processing accuracy, and is easy to operate, in order to solve the problems of low efficiency, high cost, poor accuracy, and technological gap in manual processing. Utility Model Content

[0005] This utility model provides a multi-functional chisel surface machine to solve the problems existing in the prior art.

[0006] To achieve the above objectives, this utility model provides a multi-functional chiseling machine, comprising: a fixed base, on which racks are symmetrically arranged on both sides, and x-axis traveling frames are slidably connected to the racks via traveling wheels; an electrical control cabinet is provided on the side of the x-axis traveling frame, and a bracket is fixedly connected between the two x-axis traveling frames, with a y-axis traveling head slidably connected to the bracket; the y-axis traveling head is located directly above the fixed base, and a pneumatic hammer is provided at its bottom, with a detachable cutting tool at the open end of the pneumatic hammer.

[0007] Preferably, a Y-axis motor is provided at one end of the bracket near the electrical control cabinet, and the Y-axis motor is connected to a lead screw; a lead screw nut is sleeved on the lead screw, and the lead screw nut is fixedly connected to the Y-axis traveling head through a connector. The Y-axis motor drives the lead screw to rotate, which in turn drives the lead screw nut to move on the lead screw, thereby realizing the movement of the Y-axis traveling head, and finally realizing the Y-axis movement of the tool.

[0008] Preferably, the Y-axis traveling head includes a fixed slide plate, with pulleys at both ends of the fixed slide plate, which assist the Y-axis traveling head in sliding on the bracket; the fixed slide plate has a lifting screw inside, which is connected to the movable slide plate through a connector; the top of the lifting screw is also connected to a Z-axis lifting motor through a connecting rod, and the rotation of the lifting screw drives the movable slide plate to move up and down.

[0009] Preferably, the movable slide plate is connected to the hammer head fixing plate via an adjusting screw, and an annular groove is provided at the connection between the movable slide plate and the adjusting screw, so that the angle of the hammer head fixing plate can be changed through the annular groove; a pneumatic hammer head is fixedly connected to the movable slide plate.

[0010] Preferably, the pneumatic hammer head is provided with a compressed air inlet pipe on its side, and a pressure control valve is provided at the other end of the compressed air inlet pipe. The pressure control valve is connected to a pressure tank to provide power to the pneumatic hammer head. The bottom of the pneumatic hammer head is provided with a piston, and a detachable blade is provided on the piston.

[0011] Preferably, the two x-axis traveling frames are equipped with x-axis traveling motors, and the x-axis traveling motors are equipped with reducers. The reducers are equipped with motor mounting bases. The bottom of the reducers is connected to gears through a coupling. The gears mesh with racks. The x-axis traveling motors drive the gears to rotate, so that the gears travel on the racks along the x-axis. The whole assembly drives the two x-axis traveling frames to travel along the x-axis on the fixed base.

[0012] Preferably, the two x-axis traveling frames are symmetrically provided with two traveling wheels on the sides and bottom. The traveling wheels on the sides allow the two x-axis traveling frames to slide on the fixed base, while the traveling wheels on the bottom slide on the bottom of the fixed base. This maintains the sliding force of the two x-axis traveling frames and clamps the fixed base, ensuring that the x-axis traveling frames slide stably on the fixed base.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] Significantly improves processing efficiency: Through coordinated control of x, y, and z axis servo motors, the pneumatic hammer head achieves automated movement and striking, replacing manual hammering action and enabling continuous, uninterrupted operation. Compared to manually processing 7-10㎡ of board per day, this equipment can process 40-60㎡ per day, increasing efficiency several times over and meeting the needs of mass production.

[0015] Significantly reduces processing costs: It reduces reliance on skilled workers, requiring only one operator with simple training to complete the processing on one machine, reducing labor costs by more than 60%; at the same time, the equipment adopts high-strength wear-resistant materials and oil-free pneumatic design, resulting in a low failure rate and low frequency of consumable replacement, making long-term maintenance costs significantly lower than manual processing.

[0016] Improved processing precision and consistency: PLC programming precisely controls the x and y axis movement paths and z-axis striking depth, combined with an adjustable hammerhead fixing plate, ensuring uniform spacing, depth, and width of the texture. While manual processing can result in texture errors of ±5mm, this equipment can control the error within ±0.5mm, significantly enhancing the decorative effect of the stone.

[0017] Enhanced ease of operation and adaptability: Equipped with an electrical control cabinet to enable visual parameter settings, the operator only needs to input parameters such as board size, curvature (curved board), and texture specifications, and the equipment can automatically calculate and execute the processing. No professional stonemason skills are required, and older or novice operators can become proficient in operation after 1-2 days of training.

[0018] Expanding the processing range: It can be adapted to flat slabs and inner and outer curved slabs (automatic adaptation can be achieved by inputting radius / diameter parameters). The pneumatic hammer head can be replaced with different specifications of alloy cutters to meet the processing needs of various widths of textures and adapt to diverse stone decoration scenarios.

[0019] Improved processing stability and safety: The X-axis traveling frame clamps the fixed base with side and bottom traveling wheels, ensuring smooth sliding without shaking; the pneumatic hammer head adopts an oil-free piston design to avoid oil stains on the stone, while the pressure control valve can adjust the striking force to prevent excessive damage to the stone, making the processing process safer and more stable.

[0032] Please see the appendix Figure 1-5 The present invention discloses a multifunctional chiseling machine, comprising: a fixed base 10, on which racks 8 are symmetrically arranged on both sides, and x-axis traveling frames 11 are slidably connected to the racks 8 on both sides via traveling wheels 9; an electrical control cabinet 1 is provided on the side of the x-axis traveling frames 11, and a bracket is fixedly connected between the two x-axis traveling frames 11, on which a y-axis traveling head 12 is slidably connected; the y-axis traveling head 12 is located directly above the fixed base 10, and a pneumatic hammer head 2 is provided at the bottom, and a cutter 13 is detachably provided at the open end of the pneumatic hammer head 2.

[0033] Specifically, multiple support legs are bolted to the bottom of the fixed base 10, allowing ordinary stones to rest reliably on the fixed base 10 under their own weight. Clamps can also be installed on the surface of the fixed base 10 along the x-axis or y-axis to hold the stones. The cutting tool 13 is made of alloy. The pneumatic hammer head 2 mounts the cutting tool 13 via a quick-change interface, which can be a snap-fit ​​or threaded connection.

[0034] When in use, place the plate flat in the middle of the fixed base 10. When the stone is too small, fixing points can be set at the four corners of the stone using bolts and metal plates. Input the specific data of the stone into the electrical control cabinet 1.

[0035] To further optimize the above technical solution, a y-axis motor 6 is provided at one end of the bracket near the electrical control cabinet 1, and the y-axis motor 6 is connected to a lead screw 7; a lead screw nut 101 is sleeved on the lead screw 7, and the lead screw nut 101 is fixedly connected to the y-axis traveling head 12 through a connector 100. The y-axis motor 6 drives the lead screw 7 to rotate, and then drives the lead screw nut 101 to travel on the lead screw 7, thereby realizing the movement of the y-axis traveling head 12, and finally realizing the y-axis movement of the tool 13.

[0036] Specifically, the Y-axis motor 6 is fixed to the end of the bracket near the electrical control cabinet 1 via a flange, and the motor output shaft is connected to the lead screw 7 via a coupling; the lead screw nut 101 is on the lead screw 7, and its outer side is welded and fixed to the Y-axis traveling head via a connector 100; the bracket is equipped with a guide rail, and the pulley on the Y-axis traveling head 12 cooperates with the guide rail. The electrical control cabinet 1 sends a signal to the Y-axis motor 6, which drives the lead screw 7 to rotate forward or reverse, and the lead screw nut 101 moves along the axial direction of the lead screw 7, thereby driving the Y-axis traveling head 12 to move along the guide rail in the Y direction via the connector 100, realizing the Y-axis position adjustment of the tool 13.

[0037] When in use, input the stone processing length into the electrical control cabinet 1, and the equipment will automatically calculate the number of rotations of the y-axis motor, drive the y-axis traveling head to move along the set path, and complete continuous processing in conjunction with the x-axis and pneumatic hammer 2.

[0038] To further optimize the above technical solution, the Y-axis traveling head 12 includes a fixed slide plate 42, with pulleys at both ends of the fixed slide plate 42, which assist the Y-axis traveling head 12 in sliding on the bracket; the fixed slide plate 42 is equipped with a lifting screw 43 inside, which is connected to the movable slide plate 46 through a connector; the top of the lifting screw 43 is also connected to the Z-axis lifting motor 4 through a connecting rod 41, and the rotation of the lifting screw 43 drives the movable slide plate 46 to move up and down.

[0039] Specifically, pulleys are installed at both ends of the fixed slide plate 42, and the pulleys are engaged in the grooves of the bracket; a lifting screw 43 is vertically installed inside the fixed slide plate 42, the bottom of the screw is fixed by a bearing, and the top is connected to the output shaft of the Z-axis lifting motor 4 through a connecting rod 41; the movable slide plate 46 is connected to the lifting screw 43 through a nut seat and slides in cooperation with the side guide rail of the fixed slide plate 42. After receiving the signal from the electrical control cabinet 1, the Z-axis lifting motor 4 rotates, which drives the lifting screw 43 to rotate through the connecting rod 41. The nut seat moves up and down along the screw, thereby driving the movable slide plate 46 to rise and fall along the fixed slide plate 42 in the Z-axis direction, realizing the height adjustment of the pneumatic hammer head 2.

[0040] When in use, the Z-axis stroke parameters are set in the electrical control cabinet 1 according to the thickness of the stone and the depth of the texture. The Z-axis lifting motor 4 drives the lifting screw 43 to lower the pneumatic hammer head 2 to the processing position. When striking, it reciprocates at the set depth.

[0041] To further optimize the above technical solution, the movable slide plate 46 is connected to the hammer head fixing plate 45 through the adjusting screw 44. The movable slide plate 46 and the adjusting screw 44 are provided with an annular groove, which realizes the angle change of the hammer head fixing plate 45. A pneumatic hammer head 2 is fixedly connected to the movable slide plate 46.

[0042] Specifically, the movable slide plate 46 has screw holes, through which the adjusting screw 44 passes and connects to the hammer head fixing plate 45; an annular groove is machined at the contact point between the movable slide plate 46 and the adjusting screw 44, and the pneumatic hammer head 2 is fixed to the movable slide plate 46 by bolts. Loosening the adjusting screw 44 allows the hammer head fixing plate 45 to rotate around the adjusting screw within the annular groove range (angle range 40°-90°). After adjusting to the desired angle, tightening the adjusting screw 44 secures the pneumatic hammer head 2, thus achieving angle adaptation.

[0043] When using the equipment to process stone, loosen the adjusting screw 44 and rotate the movable slide plate 46 according to the required tilt angle. After confirming the angle with the angle gauge, fix it to ensure that the cutter 13 is in contact with the stone before starting the equipment to process.

[0044] To further optimize the above technical solution, the pneumatic hammer head 2 is provided with a compressed air inlet pipe 132 on its side, and a pressure control valve 3 is provided at the other end of the compressed air inlet pipe 132. The pressure control valve 3 is connected to the pressure tank to provide power to the pneumatic hammer head 2. The bottom of the pneumatic hammer head 2 is provided with a piston 131, and a detachable blade 13 is provided on the piston 131.

[0045] Specifically, the pneumatic hammer head 2 has an air inlet port welded to its side. One end of the compressed air inlet pipe 132 is connected to the port, and the other end is connected to the pressure control valve 3. The pressure control valve 3 is connected to the pressure tank through a pipe. The bottom of the pneumatic hammer head 2 is equipped with a piston 131, and the bottom of the piston 131 has a groove. The cutting tool is detachably connected to the piston 131 through the groove. The compressed air output from the pressure tank is regulated by the pressure control valve 3 and then enters the pneumatic hammer head 2 through the compressed air inlet pipe 132, pushing the piston 131 to reciprocate at a high frequency (frequency 30-100 times / second), which drives the cutting tool 13 to strike the stone surface to form textures. The pressure control valve 3 can adjust the air inlet pressure to change the striking force.

[0046] When in use, adjust the pressure to 1-3MPa through the pressure control valve 3 according to the hardness of the stone (e.g., granite is harder and requires higher pressure); during processing, compressed air is continuously supplied, and the piston 131 drives the tool 13 to strike automatically. When changing the tool 13, turn off the air source, remove the old tool 13 and insert the new tool 13.

[0047] To further optimize the above technical solution, the two x-axis walking frames 11 are equipped with x-axis walking motors 5, and a reducer 51 is provided under the x-axis walking motors 5. The reducer 51 is equipped with a motor mounting base 52. The bottom of the reducer 51 is connected to a gear 54 through a coupling 53. The gear 54 is meshed with a rack 8. The x-axis walking motors 5 drive the gear 54 to rotate, so that the gear 54 moves on the rack 8 along the x-axis. The whole assembly drives the two x-axis walking frames 11 to move along the x-axis on the fixed base 10.

[0048] Specifically, the x-axis travel motor 5 is bolted to the motor mounting base 52, and the motor output shaft is connected to the input shaft of the reducer 51. The output shaft of the reducer 51 is connected to the gear 54 via a coupling 53, and the gear 54 meshes with the rack 8 on the fixed base 10. The motor mounting base 52 is welded to the side of the x-axis travel frame 11. The electrical control cabinet 1 sends a signal to the x-axis travel motor 5. After being reduced in speed by the reducer 51, the motor drives the gear 54 to rotate. The gear 54 meshes with the rack 8 to generate a horizontal driving force, which drives the x-axis travel frame 11 to move along the rack in the x-direction, thereby achieving overall position adjustment.

[0049] When in use, input the stone processing length in the x-axis direction into the electrical control cabinet 1. The equipment will automatically calculate the motor rotation parameters and drive the x-axis walking frame 11 to move at the set speed, cooperating with the y-axis and pneumatic hammer 2 to complete the stone processing.

[0050] To further optimize the above technical solution, two traveling wheels 9 are symmetrically provided on the sides and bottom of the two x-axis traveling frames 11. The traveling wheels 9 on the sides allow the two x-axis traveling frames 11 to slide on the fixed base 10, and the traveling wheels 9 on the bottom slide on the bottom of the fixed base 10. This maintains the sliding force of the two x-axis traveling frames 11 and also clamps the fixed base 10, ensuring that the x-axis traveling frames 11 slide stably on the fixed base 10.

[0051] Specifically, two traveling wheels 9 are symmetrically installed on the side and bottom of the x-axis traveling frame 11. The side traveling wheels 9 contact the side grooves of the fixed base 10, and the bottom traveling wheels 9 contact the bottom of the fixed base 10, forming a clamping structure for the fixed base (the clamping distance matches the thickness of the base). The traveling wheels 9 roll as the x-axis traveling frame 11 moves, reducing sliding friction; the side and bottom traveling wheels 9 together clamp the fixed base 10, preventing the x-axis traveling frame 11 from shaking or tilting during movement or processing, ensuring the stability of x-axis movement.

[0052] During use, the traveling wheels 9 automatically roll with the x-axis traveling frame 11 without any additional operation; periodically check the wear of the wheels, and replace the wheels when the wear is severe.

[0053] This application utilizes coordinated control of x, y, and z axis servo motors to automate the movement and striking of the pneumatic hammer head 2, replacing manual striking actions and enabling continuous, uninterrupted operation. Compared to manual processing of 7-10 square meters of board per day, this equipment can process 40-60 square meters per day, increasing efficiency several times over and meeting the needs of mass production. It reduces reliance on skilled workers; one machine requires only one operator with minimal training to complete the processing, reducing labor costs by over 60%. Furthermore, the equipment employs high-strength, wear-resistant materials and an oil-free pneumatic design, resulting in a low failure rate, low consumable replacement frequency, and significantly lower long-term maintenance costs compared to manual processing.

[0054] The PLC program precisely controls the movement paths of the x and y axes and the striking depth of the z axis. Combined with an adjustable hammer head fixing plate 45, it ensures that the spacing, depth, and width of the texture are uniform. The texture error of manual processing can reach ±5mm, while the error of this equipment can be controlled within ±0.5mm, which greatly improves the decorative effect of stone.

[0055] Equipped with an electrical control cabinet, the equipment enables visual parameter settings. Operators only need to input parameters such as board size, curvature (curved board), and texture specifications, and the equipment can automatically calculate and execute the processing. No professional stonemason skills are required, and older or novice operators can become proficient in operation after 1-2 days of training.

[0056] The equipment can be adapted to flat slabs and inner and outer curved slabs (automatic adaptation is achieved by inputting radius / diameter parameters). The pneumatic hammer head 2 can be replaced with alloy cutters 13 of different specifications to meet the processing needs of various widths of textures and adapt to diverse stone decoration scenarios.

[0057] The x-axis walking frame 11 clamps the fixed base 10 with the side and bottom walking wheels 9, and slides smoothly without shaking; the pneumatic hammer head 2 adopts an oil-free piston design to avoid oil stains from contaminating the stone, while the pressure control valve 3 can adjust the striking force to prevent excessive damage to the stone, making the processing process safer and more stable.
