Description

Technical Field

[0001] This invention relates to the field of stone processing machinery technology, and in particular to a multifunctional chamfering, cutting and drilling device. Background Technology

[0002] With the rapid development of society and economy, various types of stone are widely used in the construction field. However, existing stone materials all require processing before application. Stone is a high-end building decoration material, and corner designs are often needed during decoration. Currently, the common method is to bevel the edges of two pieces of stone to 45 degrees and then splice them together. However, directly cutting at a 45-degree angle can easily cause chipping at the stone edges, affecting aesthetics. Furthermore, applying too little glue when splicing directly can lead to an unstable connection and separation of the two stone slabs. Applying too much glue can result in excessive glue overflow at the joint, also affecting aesthetics. To ensure a stable and aesthetically pleasing connection, such as... Figure 1 As shown, producers typically create a glue groove on a 45-degree slope to connect two stone slabs. However, the current manual method requires highly skilled workers, is inefficient, and has low economic benefits. Summary of the Invention

[0038] To improve the ease of combining the trimming device and the glue tank trimming device and to facilitate their disassembly, the magnetic adsorption device includes: an electromagnetic adsorption plate 28 disposed on the first slide 5 and located on one side of the second slide 20, and a metal structural plate 29 disposed on the second slide 20 and located on one side of the first slide 5 for being adsorbed by the electromagnetic adsorption plate 28 when the electromagnetic adsorption plate 28 is activated.

[0039] To improve the functionality of the workbench 2, the workbench 2 is also equipped with a flip-fixing device for fixing stone slabs and expanding the placement area of ​​the workbench 2. The flip-fixing device includes: a flip frame 30 hinged to the workbench 2, a fixing device for positioning the stone slab on the flip frame 30, and a rotating device between the flip frame 30 and the workbench 2 for controlling the flip frame 30 to be in a flat or vertical state. The rotating device includes: a 90-degree arc-shaped hole 31 opened on the flip frame 30, a limiting rod 32 on the workbench 2 that passes through the 90-degree arc-shaped hole 31 to prevent the flip frame from rotating excessively, and a fourth telescopic member 33 hinged to the workbench 2. The telescopic rod of the fourth telescopic member 33 is hinged to the flip frame 30 to drive the flip frame 30 to rotate along the hinge point between the flip frame 30 and the workbench 2.

[0040] To prevent the stone slab from moving during processing, the fixing device includes: a plurality of fifth telescopic members 34 locked on the flipping frame 30, and rubber pads 35 provided on the telescopic rods of the fifth telescopic members 34 to enhance the clamping force and prevent damage to the stone slab.

[0041] To facilitate the movement of the stone slab after processing, the first support base 13 is also equipped with a lifting device to facilitate the user to grab the cut stone slab and avoid the stone affecting subsequent cutting. The lifting device includes: a sixth telescopic member 36 fixedly installed on the side of the first support base 13, a support frame 37 connected to the telescopic rod of the sixth telescopic member 36, and a plurality of suction cups 38 fixedly connected to the support frame 37. The suction cups 38 are also connected to a vacuum device, which includes: a vacuum pump 39 fixedly installed on the first slide table 5, and a plurality of pipes (not shown in the figure) connected to the vacuum pump 39 for communicating with the suction cups 38.

[0042] To facilitate the forward and backward sliding of the crossbeam 3, the forward and backward sliding device includes: an electric slide rail 40 disposed on the left or right side of the frame 1, a third slide table (not shown in the figure) disposed on the electric slide rail 40, a second slide rail 41 disposed on the frame 1 on the opposite side of the electric slide rail 40, and a fourth slide table (not shown in the figure) disposed on the second slide rail 41. The crossbeam 3 is disposed on the third slide table (not shown in the figure) and the fourth slide table (not shown in the figure).

[0043] The first telescopic component 19, the second telescopic component 22, the third telescopic component 23, the fourth telescopic component 33, the fifth telescopic component 34, and the sixth telescopic component 36 can all be telescopic cylinders or telescopic motors, and the first rotating component 15, the second rotating component 25, and the third rotating component 27 can all be rotating cylinders or rotating motors.

[0044] Working principle: When in use, place the stone slab on the workbench 2, then activate the fourth telescopic component 33 to retract the telescopic rod, which will cause the flip plate to flip upward until the limit rod 32 resists the 90-degree arc hole 31. At this time, the fifth telescopic component 34 is activated to press the stone slab tightly on the workbench 2, thus completing the fixing of the stone slab.

[0045] Then, the second reduction motor 14 starts and drives the first rotating part 15 to rotate and adjust its angle. Then, the first reduction motor 11 starts and drives the worm gear 12 to rotate, thereby driving the worm wheel 9 to rotate, which in turn drives the rotating shaft 8 to rotate, so that the first rotating part 15 is adjusted to a suitable direction. Then, the magnetic adsorption device is activated, and the electromagnetic adsorption plate 28 on the first slide 5 is energized to generate magnetic force, thereby adsorbing the metal structure plate 29 on the second slide 20, completing the connection between the first slide 5 and the second slide 20. Finally, the first telescopic part 19, the second telescopic part 22, and the third telescopic part 23 respectively drive the rotating box 7, the second support base 24, and the third support base 26 to move downward, so that the first rotating part 15, the second rotating part 25, and the third rotating part 27 are at a suitable height.

[0046] At this time, the third reduction motor starts, driving the threaded rod 17 to rotate, causing the first slide table 5 to slide along the first slide rail 4, thereby driving the second slide table 20 to slide together. The first rotating part 15, the second rotating part 25, and the third rotating part 27 start. The slice on the first rotating part 15 first cuts the stone slab edge to a similar angle of 45 degrees. Then the grinding disc on the second rotating part 25 trims the stone slab edge to a 45-degree angle. Finally, the third rotating part 27 cuts a glue groove on the 45-degree inclined surface, thus completing the processing.

[0047] After processing, the fifth telescopic component 34 is activated to release the pressure on the stone slab, and the fourth telescopic component 33 drives the telescopic rod to extend, which in turn drives the flip plate to flip downward until the limit rod 32 resists the 90-degree arc hole 31.

[0048] The first telescopic component 19, the second telescopic component 22, and the third telescopic component 23 respectively drive the rotating box 7, the second support base 24, and the third support base 26 to move upward. At this time, the first slide 5 slides to the left, thereby driving the second slide 20 to slide to the left. Then, the electromagnetic adsorption plate 28 stops being powered, disconnecting the first slide 5 from the second slide 20. The electric slide rail 40 starts, driving the third slide to move, thereby driving the crossbeam 3 to move. When it moves to the appropriate position, the sixth telescopic component 36 starts, driving the support frame 37 to slide downward until the suction cup 38 resists the stone slab. At this time, the vacuum pump 39 starts, extracting the air from the suction cup 38, thereby adsorbing the stone slab. Then, the sixth telescopic component 36 moves upward, causing the stone slab to suspend in the air. Finally, under the action of the third reduction motor (not shown in the figure) and the electric slide rail 40, the stone slab is moved to the predetermined position.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions above are merely illustrative of the principles of the present invention.
