Description

Technical Field

[0001] This utility model belongs to the field of stone processing equipment, and in particular relates to a stone grooving machine capable of deep cutting to a fixed thickness. Background Technology

[0002] With the rapid development of existing technologies, the application of stone has shifted from traditional building materials to materials for mechanical equipment. Taking the crossbeam of an existing gantry milling machine as an example, stone crossbeams, compared to traditional steel structure crossbeams, have the characteristics of long-term stability and no deformation, which can effectively reduce the frequency of calibration. At the same time, they can suppress processing chatter, improve surface quality, and are maintenance-free and corrosion-resistant, thus extending their service life. This has led to the wider application of stone.

[0003] Therefore, the requirements for stone processing are becoming increasingly stringent, with more and more types and quantities of grooves, and higher precision in the flatness of the stone. Existing stone processing machines generally use saw blades or drill bits, which cannot efficiently complete high-precision thickness determination across the entire flat surface. Their deep cutting capabilities are insufficient, resulting in low efficiency and poor millimeter-level precision, failing to meet wire-level accuracy requirements. For irregular shapes, after using saw blades to create grooves, the bottom of the groove is typically treated by saw blade scoring, which is time-consuming and yields poor smoothness and precision. Utility Model Content

[0004] This utility model addresses the technical problems existing in current stone processing by proposing a stone grooving machine with reasonable design, simple structure, convenient processing, and the ability to effectively process irregularly shaped stones with deep cutting and fixed thickness.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a stone grooving machine capable of deep cutting to a fixed thickness, including a gantry frame and a cutting mechanism that can be slidably and vertically mounted on the crossbeam of the gantry frame. It also includes a rotary planer mechanism and a milling mechanism that can be slidably and vertically mounted on the crossbeam of the gantry frame. The rotary planer mechanism includes a vertically mounted roller planer head, which is rotatably mounted on the crossbeam of the gantry frame. The roller planer head includes a disc-shaped planer head body and planing blocks distributed in a ring at intervals on the circumference of the planer head body. The planing blocks are cuboid in shape, and their two ends are flush with the sides of the planer head body. The milling mechanism includes a milling cup head that is horizontally rotatably mounted on the crossbeam of the gantry frame. The milling cup head includes a columnar milling cup head body and milling cup blocks located at the bottom of the milling cup head body. The milling cup blocks are evenly distributed in a ring at the bottom of the milling cup head body. The planing blocks and milling cup blocks are made of ultra-hard material.

[0006] Preferably, the cutting mechanism, the planing mechanism, and the milling mechanism are located on both sides of the gantry frame beam.

[0007] Preferably, the crossbeam of the gantry frame is provided with a sliding mechanism for controlling the sliding of the cutting mechanism, the planing mechanism, and the milling mechanism. The sliding mechanism includes an upper sliding plate disposed above the crossbeam of the gantry frame and a lower sliding plate disposed below the crossbeam of the gantry frame. A side sliding plate is also disposed between the upper sliding plate and the lower sliding plate. The side sliding plates are disposed on both sides of the crossbeam of the gantry frame. The upper sliding plate, the lower sliding plate, and the side sliding plates are provided with sliders on the surfaces opposite to the crossbeam of the gantry frame. The crossbeam of the gantry frame is provided with a track that cooperates with the sliders.

[0008] Preferably, a drive screw is also provided on the crossbeam of the gantry frame, and a screw nut that cooperates with the drive screw is provided at the bottom of the upper slide plate. The drive screw is rotatably mounted on the crossbeam of the gantry frame.

[0009] Preferably, the crossbeam of the gantry frame is provided with a rack, and the sliding mechanism also includes a sliding motor that cooperates with the rack. The power end of the sliding motor is fitted with a gear, and the gear is meshed with the rack.

[0010] Preferably, the side slide plate is provided with a lifting mechanism for controlling the lifting of the cutting mechanism, the planing mechanism and the milling mechanism. The lifting mechanism includes a lifting plate slidably mounted on the side slide plate, a lifting motor is provided on the top of the lifting plate, a lifting screw is connected to the power end of the lifting motor, and a lifting nut that cooperates with the lifting screw is provided on the side slide plate.

[0011] Preferably, the lifting plate used to set the milling mechanism is also provided with a polishing mechanism, which includes a polishing motor set on the lifting plate and a polishing disc set on the power end of the polishing motor.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention provides a stone grooving machine capable of deep cutting and thickness determination. The gantry structure uses marble components, ensuring high precision; the overall machine tool accuracy reaches the micrometer level. It features a three-lifting-plate configuration, a wraparound middle frame, and a Z-axis dovetail rail, providing sufficient rigidity for deep cutting. The first lifting plate uses a roller planer head for cutting; the planer head itself can reach a thickness of 50mm, with a single cutting depth of 10mm, enabling efficient thickness determination. The second lifting plate uses a milling head, achieving high surface finish and micrometer-level precision. The third lifting plate uses a saw blade, capable of cutting all grooves, including bevel grooves, in one pass, requiring minimal manual operation. After evenly spaced cutting, residual material is knocked away, and the roller planer head continues cutting to the desired thickness. Because the roller planer head is more than 10 times thicker than the saw blade, it is more efficient. After thickness determination, the milling head further improves precision and surface finish. The third lifting plate can also be equipped with a polishing head to further enhance the surface finish. Attached Figure Description

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] 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.

[0017] Example 1, such as Figures 1-6As shown, this embodiment aims to provide a grooving machine that can better handle stone surfaces and grooves with high precision, in order to solve the problems existing in the grooving and surface processing of irregular-shaped stones. Therefore, this embodiment provides a stone grooving machine capable of deep cutting to a fixed thickness, including a gantry frame 1 and a cutting mechanism 4 that is slidably and vertically mounted on the crossbeam 13 of the gantry frame. Similar to existing gantry frames 1, the gantry frame 1 provided in this embodiment also includes a crossbeam 13 and side beams 11 mounted on both sides of the crossbeam 13. A side beam slide block 12 is provided between the crossbeam 13 and the side beams 11 to support the crossbeam 13. A [missing information - likely a design feature] is provided at the bottom of the side beam slide block 12. A lead screw and nut are provided, and sliders are provided on both sides of the lead screw and nut. A lead screw that cooperates with the lead screw and nut and a motor that drives the lead screw to rotate are provided on the side beam 11, as well as a track that cooperates with the sliders. In this way, under the action of the motor, the crossbeam 13 can move back and forth along the long side of the side beam 11. The cutting mechanism 4 is a common existing structure, which includes a saw blade 42 and a cutting motor 41. In this embodiment, the cutting motor 41 and the saw blade 42 are connected by a belt, that is, the cutting motor 41 and the main shaft of the saw blade 42 are connected by a belt. The above structure is a common existing structure, so it will not be described in detail in this embodiment.

[0018] Considering that the main problem with the saw blade 42 in cutting the groove is that the thickness of the saw blade 42 is too thin, which means that the groove can only be processed by scratching when the saw blade 42 cuts the groove, in this embodiment, a planing mechanism 2 and a milling mechanism 3 are also provided on the crossbeam 13. Of course, the planing mechanism 2 and the milling mechanism 3 can also be slidably and vertically arranged on the crossbeam 13 to meet the processing needs.

[0019] Specifically, the rotary planer mechanism 2 includes a vertically positioned rotary planer head 21, which is rotatably mounted on the crossbeam 13 of the gantry frame 1. The rotary planer mechanism 2 also includes a square-shaped mounting base. A rotary planer motor 22 is mounted on the top of the mounting base, and a rotary planer shaft is mounted on the bottom of the mounting base. The rotary planer head 21 is fitted onto the rotary planer shaft. The rotary planer shaft and the rotary planer motor 22 are connected by a belt. Direct drive is also possible, but if the rotary planer head 21 gets stuck, it can easily cause the motor to burn out. Belt connection is preferred.

[0020] The roller planer head 21 includes a disc-shaped planer head body 211 and planing blocks 212 arranged in a ring at intervals on the circumference of the planer head body 211. The overall shape of the roller planer head 21 is similar to that of the saw blade 42, but its thickness can reach 50mm, which is more than ten times the thickness of the saw blade 42. The planing blocks 212 are rectangular and their two ends are flush with the sides of the planer head body 211. In this way, the cutting surface of the roller planer head 21 is wide, which has the ability to cut deeply. The single cutting depth can reach 10mm, which can quickly process slots and holes and has high efficiency in fixed thickness processing. In addition, the planing blocks 212 are arranged at intervals to facilitate the removal of stone chips and prevent stone dust from clogging.

[0021] The milling mechanism 3 includes a milling head 31 horizontally rotatably mounted on the crossbeam 13 of the gantry frame 1, and a milling motor 32 that drives the milling head 31 to rotate. The milling head 31 includes a cylindrical milling head body 311 and milling blocks 312 disposed at the bottom of the milling head body 311. The milling blocks 312 are evenly distributed in a ring at the bottom of the milling head body 311. The milling head 31 is similar to a drill bit used for drilling large holes, but the milling head body 311 is a cylindrical structure, not a tubular one. The milling blocks 312 are also thicker, thus primarily serving a rapid smoothing function. Since the cutting block 212 and the milling block 312 are designed for stone, they are made of a superhard material. They can be diamond teeth or other hard alloy teeth.

[0022] With the above settings, during processing, the saw blade 42 is highly efficient at grooving. After cutting at equal intervals, the saw blade 42 can knock off the remaining fragments. However, a lot of residual material remains at the bottom after knocking off the fragments. Continuing to remove the remaining material with the saw blade 42 is inefficient due to its narrowness. However, using the roller planer head 21 is highly efficient at removing the remaining material and can achieve a fixed thickness. If higher precision is desired, the bottom surface can be milled with the milling head 31. Of course, the milling head 31 is mainly used for surface treatment of the stone. Through the above settings, rapid processing of irregularly shaped stone is effectively achieved.

[0023] Considering the limited length of the crossbeam 13, in order to meet the processing needs of larger-sized stones, in this embodiment, the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3 are located on both sides of the crossbeam 13 of the gantry frame 1. In this way, the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3 have a wider range of movement on the crossbeam 13, which meets the needs of processing larger-sized stones, and the front and rear weight distribution is more reasonable.

[0024] Considering the numerous advantages of the stone beam 13, in this embodiment, the beam 13 is also made of marble. To accommodate the beam 13, in this embodiment, a sliding mechanism 5 is provided on the beam 13 of the gantry frame 1 to control the sliding of the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3. The sliding mechanism 5 includes an upper sliding plate 51 positioned above the beam 13 of the gantry frame 1 and a lower sliding plate 52 positioned below the beam 13 of the gantry frame 1. A side sliding plate 53 is also provided between the upper sliding plate 51 and the lower sliding plate 52. The side sliding plate 53 is positioned on the gantry frame 1... On both sides of the crossbeam 13, the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3 are respectively mounted on different side slide plates 53. Slider blocks are provided on the surfaces of the upper slide plate 51, lower slide plate 52, and side slide plates 53 opposite to the crossbeam 13 of the gantry frame 1. A track is provided on the crossbeam 13 of the gantry frame 1 to cooperate with the sliders. A drive screw is also provided on the crossbeam 13 of the gantry frame 1. A screw nut cooperating with the drive screw is provided at the bottom of the upper slide plate 51. A sliding motor 54 is installed on the crossbeam 13 to enable the drive screw to rotate. This fulfills the requirement for the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3 to slide along the crossbeam 13.

[0025] Of course, the driving method of the sliding mechanism 5 can also be a combination of motor and rack. For example, a rack can be installed on the top of the crossbeam 13, and a sliding motor can be installed on the upper slide plate 51. The power end of the sliding motor is fitted with a gear to form a combination with the rack to drive the sliding mechanism to move. Alternatively, the rack can be installed on the side of the crossbeam 13, and the width of the side slide plate on the side of the cutting mechanism 4 can be increased to install the sliding motor and form a combination with the rack to drive the sliding mechanism to move.

[0026] In the above structure, the upper sliding plate 51, lower sliding plate 52, and side sliding plate 53 form a ring-shaped middle frame mechanism. Sliding blocks are installed around the frame, giving it high rigidity and effectively counteracting forces from all sides, especially the upward force during cutting, ensuring deep cutting capability. The crossbeam 13 is made of a single piece of marble with high precision, and guide rails are installed on all four sides, ensuring high precision for the slidingly connected middle frame. The four-ringed marble crossbeam 13 structure provides both deep cutting rigidity and high planar precision. High precision places strict requirements on assembly. To address assembly errors, the upper sliding plate 51 and lower sliding plate 52 are installed vertically, making them easy to disassemble and re-grind for errors, further improving installation accuracy and the precision of the grooving machine.

[0027] To facilitate the control of the lifting and lowering of the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3, a lifting mechanism 6 is provided on the side slide plate 53 for controlling the lifting and lowering of the cutting mechanism 4, the planing mechanism 2, and the milling mechanism 3. Each side slide plate 53 corresponds to one lifting mechanism 6. Specifically, the lifting mechanism 6 includes a lifting plate 61 slidably mounted on the side slide plate 53. A lifting motor 62 is mounted on the top of the lifting plate 61, and a lifting screw 63 is connected to the power end of the lifting motor 62. A lifting nut 55 is provided on the side slide plate 53 to cooperate with the lifting screw 63. In this embodiment, the lifting nut 55 is used for fixing, and the rotation of the lifting screw 63 is used to achieve the lifting and lowering of the entire lifting plate 61. In this embodiment, to limit the lifting and lowering of the lifting plate 61, dovetail grooves are provided on both sides of the side slide plate 53, and protrusions that cooperate with the dovetail grooves are provided on both sides of the lifting plate 61. The dovetail groove structure is stable, has a large connection area, can withstand great pressure and tension, and has a strong load-bearing capacity, further ensuring the deep cutting capability.

[0028] To further improve efficiency and functionality, if the stone only requires polishing and not grinding, a polishing mechanism 7 is also provided on the lifting plate 61 used for the milling mechanism 3. The polishing mechanism 7 includes a polishing motor 71 mounted on the lifting plate 61 and a polishing disc 72 mounted on the power end of the polishing motor 71. The polishing disc 72 is flush with the milling head 31 and can be raised and lowered using a cylinder to select whether polishing is used. This allows for further polishing. Of course, if polishing is not required, the polishing mechanism 7 can be omitted.

[0029] The above setup effectively achieves integrated processing of irregularly shaped stone with a high degree of automation, greatly reducing the processing difficulty of existing irregularly shaped stone.

[0030] 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. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
