Description

Technical Field

[0001] The invention relates to the technical field of stone cutting, in particular to an electric stone cutting machine. Background Art

[0002] With the rapid development of modern industrial technology, the stone processing industry is also gradually upgrading its production processes and equipment. Stone cutting is a very common price step in the process of stone processing, so cutting machines and other equipment are needed. Before cutting some marble slabs, it is necessary to manually operate the clamping mechanism to clamp and fix the marble slab, but the pressure applied by the manual clamping mechanism to clamp the marble slab is difficult to control. If the clamping force is too large, it is easy to cause damage to the marble slab. If the clamping force is too small, it will affect the clamping effect of the marble slab. Especially when cutting and fixing some stones with smooth surfaces, it is difficult to fix them firmly, which will cause the stone to shake during the cutting process, resulting in the displacement of the cutting position, affecting the accuracy of stone cutting. Moreover, the position of the cutting groove on the support table of the existing cutting machine is mostly fixed. After cutting the stone once, the position of the stone needs to be readjusted so that the position to be cut is aligned with the position of the cutting groove on the support table so that the next cutting can be performed. The operation is relatively cumbersome; and the repeated adjustment and positioning of the stone not only affects the cutting efficiency, but also causes large errors due to repeated positioning, thereby affecting the cutting accuracy.

The side of the main pipe 81 is equidistantly connected to multiple first hoses 82 through pipe joints, and the other end of the first hose 82 passes through the connecting groove and is connected to one end of the branch pipe 83 through a pipe joint.

[0065] When fixing the stone, first adjust the distance between the strip support platforms 7 according to the width of the stone cut, then place the stone on the strip support platform 7, and squeeze the suction cup 92 at the lower end of the stone to shrink into the circular mounting groove 91;

[0066] At this time, the blowing and suction dual-purpose air pump 8 starts to suck air, and the air in the suction cup 92 is sucked away through the connecting pipe 93, the second hose 94, the branch pipe 83, the first hose 82, and the main pipe 81, so that the suction cup 92 is firmly adsorbed on the lower end of the stone, thereby completing the fixation of the stone, which is a smooth-surfaced plate.

[0067] When cutting, the three-axis linear module 17 first drives the electric cutting device 23 to move forward and backward to a suitable position, that is, the end of the stone cutting part. At this time, the three-axis linear module 17 drives the electric cutting device 23 to move downward, and at the same time, the upper pressure seat 21 moves to the upper end of the stone, so that the positioning pressure wheel 22 presses on the upper end of the stone to further fix the stone;

[0068] When the three-axis linear module 17 drives the electric cutting device 23 to move left and right to cut the stone, the upper pressure seat 21 drives the positioning pressure wheel 22 to roll along the upper end of the stone, so as to position the upper end of the stone in real time. The suction cup 92 and the positioning pressure wheel 22 cooperate to firmly fix the stone to prevent the stone from shaking during the cutting process, thereby ensuring the accuracy of stone cutting.

[0069] A spray mechanism or a dust suction mechanism may be installed on the support frame 16 to remove or collect dust etc. generated by cutting.

[0070] Working principle: When cutting the stone, first adjust the position of the strip support platform 7 and the movable adsorption mechanism according to the length of the stone and the width to be cut, so that the stone can be firmly fixed and the cutting part of the stone is always in the gap between the strip support platforms 7 to prevent the strip support platform 7 from hindering the cutting of the stone. By adjusting the position of the strip support platform 7 first and then fixing the stone, it only needs to be fixed once, reducing the number of times the stone is fixed, which not only improves the work efficiency, but also reduces the error caused by repeated fixing, and greatly improves the cutting accuracy;

[0071] The movable platform 44 is driven to slide left and right along the guide adjustment groove 11 by the extension and contraction of the piston rod of the hydraulic cylinder 45, and the movable platform 44 drives the movable width adjustment mechanism 301 to move left or right, so that the two movable width adjustment mechanisms 301 are moved closer to or farther away from each other. When the movable width adjustment mechanism 301 moves, it drives the movable adsorption mechanism thereon to move left and right, so that the T-shaped positioning seat 9 in the movable adsorption mechanism slides left and right along the guide T-shaped groove 72, thereby adjusting the position of the movable adsorption mechanism, so that the movable adsorption mechanism can fix stones of different lengths, thereby improving the use range of the electric stone cutting machine;

[0072] By screwing the locking bolt 57 outward along the concave base 1, the locking bolt 57 drives the locking tooth block 54 to move through the concave block 56, so that the locking tooth block 54 is separated from the limiting gear 52;

[0073] At this time, the crank 53 is turned, and the crank 53 drives the cross-shaped rod 5 to rotate through the round rod 51, and the cross-shaped rod 5 drives the multiple cylinders 41 thereon to rotate synchronously, and the cylinders 41 drive the transmission bevel gear 42 to rotate, and the transmission bevel gear 42 drives the synchronous bevel gear 39 to rotate, and the synchronous bevel gear 39 drives the two-way transmission screw 32 to rotate, and the two-way transmission screw 32 drives the two T-shaped adjustment seats 33 thereon to move closer to or away from each other;

[0074] When the T-shaped adjustment seat 33 moves, the dovetail block 37 drives the insertion rod 38 to move synchronously, and the insertion rod 38 drives the end of the folding and telescopic frame 6 to move, so that the folding and telescopic frame 6 is retracted or opened;

[0075] When the folding telescopic frame 6 is retracted or opened, the circular shaft 62 is driven to move. When the circular shaft 62 moves, the multiple T-shaped positioning seats 9 distributed front and back are driven to move synchronously, so that the multiple T-shaped positioning seats 9 distributed front and back are moved closer to or farther away from each other. When the T-shaped positioning seats 9 move, the strip support platform 7 is driven to move, so that the multiple strip support platforms 7 are moved closer to or farther away from each other, so as to adjust the distance between the multiple strip support platforms 7.

[0076] The distance between the strip support platforms 7 is adjusted according to the width of the stone to be cut, so that the cutting position of the stone is located at the gap between the strip support platforms 7, so that the electric cutting device 23 can normally perform the stone cutting operation.

[0077] When fixing the stone, the stone is placed on the upper end of the strip support platform 7, and the lower end of the stone squeezes the suction cup 92 to shrink into the circular mounting groove 91, at which time the upper end of the suction cup 92 is tightly fitted with the lower end of the stone;

[0078] At this time, the blowing and suction dual-purpose air pump 8 starts to suck air, so that the suction cup 92 is firmly adsorbed on the lower end of the stone, thereby completing the fixing of the stone;

[0079] When cutting, the three-axis linear module 17 first drives the electric cutting device 23 to move forward and backward to a suitable position, that is, the end of the stone cutting part. At this time, the three-axis linear module 17 drives the electric cutting device 23 to move downward, and at the same time, the upper pressure seat 21 moves to the upper end of the stone, so that the positioning pressure wheel 22 presses on the upper end of the stone to further fix the stone;

[0080] When the three-axis linear module 17 drives the electric cutting device 23 to move left and right to cut the stone, the upper pressure seat 21 drives the positioning pressure wheel 22 to roll along the upper end of the stone, so as to position the upper end of the stone in real time. The suction cup 92 and the positioning pressure wheel 22 cooperate to firmly fix the stone to prevent the stone from shaking during the cutting process, thereby ensuring the accuracy of stone cutting.

[0081] After the cutting is completed, the blowing and suction dual-purpose air pump 8 is started to blow air, so that the suction cup 92 releases the adsorption and fixation of the stone, and then the cut plate can be conveniently removed. The operation is simple and convenient, and the work efficiency is greatly improved.
