Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, and in particular to a grooving device that can work simultaneously on the upper and lower parts of a stone slab. Background Technology

[0002] In the production and processing of tombstones, grooving is a crucial process. Its appearance design and craftsmanship quality are of great concern. Grooving not only affects the overall aesthetics of the tombstone, but is also closely related to the precise implementation of subsequent carving, inscription and other processes.

[0003] Traditional manual grooving requires artisans to apply considerable force continuously, which can easily lead to physical fatigue, especially for the arms and waist, which bear enormous pressure. This not only affects work efficiency but also poses a potential threat to the artisan's health. Although some mechanical equipment for stone grooving has appeared on the market, most of these machines have limited functions, and some can only perform unidirectional grooving. When processing grooves at different locations on the top and bottom of a tombstone, it is necessary to adjust the position of the equipment or change the processing method multiple times, making the operation cumbersome and inefficient. Utility Model Content

[0004] To address the issue of existing grooving methods requiring multiple position adjustments, this invention provides a grooving device that operates simultaneously on both the top and bottom of a stone slab.

[0005] The technical solution of this utility model is achieved through the following scheme: a grooving device for simultaneous upper and lower operation of a stone slab, comprising a support frame, a material storage rack, a material processing rack, an upper grooving machine, and a lower grooving machine. The material storage rack and the material processing rack are fixedly installed on the support frame. A crossbeam support frame is movably installed on the support frame. The crossbeam support frame spans across the material processing rack. A crossbeam is fixedly installed on the crossbeam support frame. A transverse movement system is provided on the crossbeam. The upper grooving machine is movably installed on the transverse movement system via a first screw lifting device. The lower grooving machine is movably installed on the crossbeam support frame via a second screw lifting device.

[0006] The slotting end of the lower slotting machine is located inside the material processing rack.

[0007] Through the above technical solution, the upper grooving machine moves up, down, left, and right in coordination with the first lead screw lifting device and the transverse movement system; the lower grooving machine can also flexibly adjust its position through the second lead screw lifting device. The upper and lower grooving machines can move in multiple dimensions and quickly and accurately reach the designated processing position. The upper and lower grooving machines simultaneously perform grooving operations on the upper and lower surfaces of the stone slab. The processing of the upper and lower surfaces can be completed in one clamping, shortening the work cycle, reducing the time for manual positioning and adjustment, and further improving processing efficiency. The crossbeam support, together with the crossbeam, forms a stable support structure, providing a reliable operating platform for the upper and lower grooving machines, effectively reducing vibration and shaking, and avoiding processing errors caused by equipment instability.

[0008] Preferably, the first screw lifting device includes a first servo motor, a first ball screw system, a first mounting base, and a first fixed base. The first fixed base is equipped with the first ball screw system, and the first mounting base is movably mounted on the first fixed base through the first ball screw system. The drive end of the first servo motor is connected to the rotating end of the first ball screw system. The upper grooving machine is mounted on the first mounting base, and the first fixed base is movably mounted on the crossbeam through a transverse system.

[0009] Through the above technical solutions, the rotational motion is precisely converted into the linear motion of the first mounting seat by the cooperation of the first servo motor and the first ball screw system, thereby achieving precise control of the lifting position of the upper grooving machine, ensuring that the depth of each grooving meets the design requirements, and improving the processing quality of the product; the first fixed seat provides a stable support foundation for the first ball screw system, ensuring the structural stability of the entire lifting device, and the first fixed seat enables the upper grooving machine to perform multi-dimensional motion through the transverse system.

[0010] Preferably, a second lead screw lifting device is fixedly installed on the side of the beam support frame away from the material storage rack.

[0011] Preferably, the second screw lifting device includes a rocker wheel, a second ball screw system, a second mounting base, and a second fixed base. The rocker wheel is connected to the rotating end of the second ball screw system. The second mounting base is movably mounted on the second fixed base through the second ball screw system. The second fixed base is fixedly mounted on the crossbeam support frame. The lower grooving machine is mounted on the second mounting base.

[0012] Through the above technical solutions, the operation of the second ball screw system can be directly and precisely controlled by manually turning the rocker wheel. The bottom slotting allows for fine-tuning, and manual operation enables more detailed perception and adjustment of the lifting height of the grooving machine. The layout of the second screw lifting device avoids interference between components and provides ample space for the storage and flow of materials.

[0013] Preferably, the support frame is provided with a number of racks and guide rails, and the crossbeam is provided with racks and guide rails.

[0014] Preferably, the traverse system includes a third servo motor, a first reducer, and a mounting bracket. The first reducer and the third servo motor are mounted on the mounting bracket. The first reducer is assembled at the output end of the third servo motor. The mounting bracket is slidably connected to the guide rail. The first lead screw lifting device is mounted on the mounting bracket.

[0015] Preferably, a first gear is installed at the output end of the first reducer, and the first gear is adapted to the rack.

[0016] Through the above technical solutions, the meshing transmission of gears and racks enables the movement of each component, achieving high-precision position control. The guide rail avoids deviation and wobbling during the movement, and the combined structure of gears, racks, and guide rails has high rigidity, capable of withstanding large external forces without deformation; the torque is increased by the speed reducer to improve load capacity.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This utility model uses a first lead screw lifting device in conjunction with a transverse system to drive the upper grooving machine to move up, down, left, and right; the lower grooving machine can also flexibly adjust its position via a second lead screw lifting device. The upper and lower grooving machines move in multiple dimensions and quickly and accurately reach the designated processing position. The upper and lower grooving machines simultaneously perform grooving operations on the upper and lower surfaces of the stone slab. The processing of both the upper and lower surfaces can be completed in one clamping, shortening the work cycle, reducing the time for manual positioning and adjustment, and further improving processing efficiency. The crossbeam support, together with the crossbeam, forms a stable support structure, providing a reliable operating platform for the upper and lower grooving machines, effectively reducing vibration and shaking, and avoiding processing errors caused by equipment instability.

[0019] 2. Through the cooperation of the first servo motor and the first ball screw system, the rotary motion is precisely converted into the linear motion of the first mounting seat, thereby achieving precise control of the lifting position of the upper grooving machine, ensuring that the depth of each grooving meets the design requirements, and improving the processing quality of the product; the first fixed seat provides a stable support foundation for the first ball screw system, ensuring the structural stability of the entire lifting device, and the first fixed seat enables the upper grooving machine to perform multi-dimensional motion through the transverse system.

[0033] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0035] A grooving device that operates simultaneously on both the top and bottom of a stone slab, such as Figures 1-5 As shown, the system includes a support frame 1, a material storage rack 110, a material processing rack 111, an upper grooving machine 2, and a lower grooving machine 3. The material storage rack 110 and the material processing rack 111 are fixedly mounted on the support frame 1. A crossbeam support frame 8 is movably mounted on the support frame 1, spanning the material processing rack 111. A crossbeam 7 is fixedly mounted on the crossbeam support frame 8. After assembly, the crossbeam support frame 8 and the crossbeam 7 form a gate shape, with the bottom slidably connected to the guide rail 12. A transverse movement system 6 is provided on the crossbeam 7. The upper grooving machine 2 is movably mounted on the transverse movement system 6 via a first screw lifting device 4, and the lower grooving machine 3 is movably mounted on the crossbeam support frame 8 via a second screw lifting device 5. The material storage rack 110 and the material processing rack 111... Both are arranged in a trapezoidal shape, with the material processing rack 111 slightly higher than the material temporary storage rack 110. This raises the plate so that the bottom of the plate is suspended, reserving a processing position for the lower grooving machine 3. The upper grooving machine 2 moves left, right, up, and down through the first screw lifting device 4 and the transverse system 6. In conjunction with the forward and backward movement of the crossbeam support frame 8, the upper grooving machine 2 can freely adjust its position in three-dimensional space to meet the grooving requirements of different positions and depths, greatly improving the flexibility and adaptability of processing. The lower grooving machine 3 moves up and down through the second screw lifting device 5. Combined with the forward and backward movement of the crossbeam support frame 8 on the support frame 1, the lower grooving machine 3 can also adjust its position within a certain range, working in coordination with the upper grooving machine 2 to achieve precise grooving of the upper and lower surfaces of the material.

[0036] The portal frame structure of crossbeam 7 and crossbeam support frame 8 has high strength and rigidity, effectively bearing the forces generated by the upper grooving machine 2, lower grooving machine 3, and during processing, ensuring the stability of the equipment during operation and reducing vibration and sway.

[0037] like Figure 3As shown, the crossbeam support frame 8 is synchronously driven by the second servo motor 9 and the fourth servo motor 10. The output end of the second servo motor 9 is equipped with a second reducer 91, and the output end of the fourth servo motor 10 is equipped with a third reducer 101. Both the output ends of the second reducer 91 and the third reducer 101 are equipped with drive gears. The drive gears are matched with the rack 11 on the support frame 1. The rotation of the drive gears drives the crossbeam support frame 8 to move. The two motors work together to ensure that the crossbeam support frame 8 is evenly stressed during movement, avoiding imbalance caused by unilateral drive, thereby ensuring that the crossbeam support frame 8 moves smoothly back and forth and reducing swaying and vibration.

[0038] The speed reducer lowers the speed and increases the torque, so that the power output by the motor is transmitted to the drive gear more smoothly, further stabilizing the rotation of the drive gear, thereby ensuring the smooth movement of the crossbeam support frame 8 and avoiding the phenomenon of unsmooth movement caused by fluctuations in motor speed or insufficient torque.

[0039] like Figure 2 As shown, the grooving end of the lower grooving machine 3 is located inside the material processing rack 111. The adjustable saw blade of the lower grooving machine 3 is located in the center of the bottom space of the material processing rack 111. Both the upper grooving machine 2 and the lower grooving machine 3 are composed of a drive motor, a rotating shaft, and an adjustable saw blade. One end of the rotating shaft is equipped with an adjustable saw blade, and the other end is equipped with a pulley. The drive motor drives the drive pulley, thereby driving the rotating shaft to rotate, causing the adjustable saw blade to rotate. The adjustable saw blade can be added or removed to adjust the grooving size and meet different grooving requirements. The drive motor of the upper grooving machine 2 is preferably a 2.2Kw four-pole motor, and the drive motor of the lower grooving machine 3 is preferably a 5.5Kw four-pole motor.

[0040] By simultaneously grooving the upper and lower surfaces of the material in one processing step, compared to the traditional method of grooving one side and then flipping the material to groove the other side, the processing time is shortened and production efficiency is improved.

[0041] like Figure 2 and Figure 3 As shown, a number of racks 11 and a number of guide rails 12 are laid on the support frame 1. Preferably, there are two racks 11 on the support frame 1 and two guide rails 12. The racks 11 and guide rails 12 are laid in pairs on the support frame 1 on both sides of the material processing rack 111.

[0042] like Figure 1 and Figure 3 As shown, a rack 11 and several guide rails 12 are laid on the crossbeam 7. The rack 11 and guide rails 12 are laid on the upper surface of the crossbeam 7. The guide rails 12 are laid on the side near the first lead screw lifting device 4. The first lead screw lifting device 4 is slidably connected to the side guide rails 12.

[0043] like Figure 1and Figure 4 As shown, the first ball screw lifting device 4 includes a first servo motor 41, a first ball screw system 42, a first mounting base 43, and a first fixed base 44. The first ball screw system 42 is mounted on the first fixed base 44. The first mounting base 43 is movably mounted on the first fixed base 44 through the first ball screw system 42. The drive end of the first servo motor 41 is connected to the rotating end of the first ball screw system 42. The upper grooving machine 2 is mounted on the first mounting base 43. The first fixed base 44 is movably mounted on the crossbeam 7 through the transverse movement system 6. The first fixed base 44 is fixed to the mounting bracket 63 of the transverse movement system 6 by bolts. The first fixed base 44 is also provided with a slide that matches the side guide rail 12, so that the whole can move smoothly laterally and provide additional guidance for the first mounting base 43, effectively preventing the first mounting base 43 from shifting or tilting during movement. The first ball screw system 42 and the second ball screw system 52 have the same structure, both consisting of a ball screw and a limiting slide.

[0044] The first servo motor 41 serves as a power source and is connected to the rotating end of the ball screw of the first ball screw system 42. It can efficiently and accurately convert the rotational motion of the motor into the linear motion of the first mounting seat 43 on the first ball screw. The servo motor, in conjunction with the ball screw system, achieves high motion accuracy, meeting the processing requirements of the product.

[0045] like Figure 3 As shown, a second screw lifting device 5 is fixedly installed on the side of the crossbeam support frame 8 away from the material storage rack 110, providing sufficient moving space for the second screw lifting device 5 and ensuring that its operation is not obstructed by the material storage rack 110.

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, the second screw lifting device 5 includes a rocker wheel 51, a second ball screw system 52, a second mounting base 53, and a second fixed base 54. The rocker wheel 51 is connected to the rotating end of the second ball screw system 52. The second mounting base 53 is movably mounted on the second fixed base 54 through the second ball screw system 52. The second fixed base 54 is fixedly mounted on the crossbeam support frame 8. The lower grooving machine 3 is mounted on the second mounting base 53. The bottom grooving is finely adjusted. Manual operation allows for more precise perception and adjustment of the lifting height of the lower grooving machine 3. The second fixed base 54 is connected to the crossbeam support frame 8 through multiple bolts, providing basic support for the lower grooving machine 3 and ensuring that it will not shake or shift due to external forces during operation. The second mounting base 53 provides a universal installation platform for the lower grooving machine 3.

[0047] like Figure 1 , Figure 2 and Figure 3As shown, the transverse system 6 includes a third servo motor 61, a first reducer 62, and a mounting bracket 63. The first reducer 62 and the third servo motor 61 are mounted on the mounting bracket 63. The first reducer 62 is mounted on the output end of the third servo motor 61. The mounting bracket 63 is slidably connected to the guide rail 12. The first lead screw lifting device 4 is mounted on the mounting bracket 63. The crossbeam 7 is generally square, with a rack 11 and guide rail 12 on its top surface. A side guide rail 12 is laid on the side where it is assembled with the first lead screw lifting device 4. A first gear is mounted on the output end of the first reducer 62. The first gear... The rack 11 is matched with the gear at the output end, and the low speed and high torque power is transmitted to the gear. The gear and rack 11 mesh to make themselves move laterally on the crossbeam 7. The end of the mounting bracket 63 is fixed to the first fixed seat 44 of the first lead screw lifting device 4. It is stably and balanced guided by the side guide rail 12, which drives it to move laterally smoothly. The lateral movement system 6 and the first lead screw lifting device 4 are assembled to form an L-shape. At this time, the guide rail 12 laid on the top surface of the crossbeam 7 and the side guide rail laid on the side assembled with the first lead screw lifting device 4 provide a double lateral movement guide for the lateral movement system 6, ensuring the stability of the lateral movement system 6.

[0048] The upper grooving machine 2, the lower grooving machine 3, the first lead screw lifting device 4, the second lead screw lifting device 5, the transverse movement system 6, the second servo motor 9, the second reducer 91, the fourth servo motor 10, and the third reducer 101 are all communicatively connected to the external control system 114. The external control system 114 is preferably a PLC controller. The external control system 114 controls the second servo motor 9 and the fourth servo motor 10 to drive simultaneously, thereby enabling the crossbeam support frame 8 to move back and forth. All parts and equipment adopt conventional models in the prior art. In addition, the circuit connection and communication connection adopt conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0049] Working principle: The worker places the stone on the material processing rack 111 and the material storage rack 110. Then, the worker uses the first screw lifting device 4 to lift the upper grooving machine 2 to process the groove on the stone.

[0050] The grooving machine 3 can be moved up and down by manually turning the rocker wheel 51, thereby processing the groove under the stone.

[0051] Furthermore, the second servo motor 9 and the fourth servo motor 10 drive the crossbeam support frame 8 to move left and right, thereby driving the upper grooving machine 2 and the lower grooving machine 3 to adjust and move, so as to achieve the purpose of grooving at the upper and lower levels simultaneously.

[0052] Whether the stone placed on the material storage rack 110 is a large piece 112 or a small piece 113, the upper grooving machine 2 can be moved above it by the transverse system 6 for grooving.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
