Description

Technical Field

[0001] The utility model relates to the field of stone cutter structures, in particular to a vertical profiling stone cutter. Background Art

[0002] Natural stone is one of the oldest civil engineering materials. It has high compressive strength, good wear resistance and durability. After processing, the surface is beautiful and decorative. It is the main material for building city walls, bridges, houses and water conservancy projects in ancient and modern civil engineering. It is also one of the main decorative materials in modern civil engineering. At the same time, if the stone is required to be decorative, it needs to be processed in a certain way before it can become a decorative material, such as a profiled stone cutter.

[0003] At present, most of the stone processing factories use profiling stone cutters to fix the stone in a relatively simple way when processing cylindrical products. For example, the lower end of the stone is fixed by a three-jaw chuck or a suction cup. This method of only fixing the bottom of the stone is not stable and is easy to fall over.

[0017] In a possible implementation manner, a plurality of threaded holes are annularly distributed on the upper surface of the turntable, and each of the threaded holes is adaptively screwed and fixed with a bolt. The bottom of the fastening screw is fixedly connected with a connecting seat, and the connecting seat is annularly distributed with connecting holes. When assembling the fastening screw, the connecting seat is placed on the turntable so that each of the connecting holes and each of the threaded holes correspond one by one, and the fixing bolt passes through the connecting hole and is screwed with the threaded hole to press the connecting seat on the turntable.

[0022] In a possible implementation, the stone cutting machine further includes a profiling control device and a control system. The profiling control device includes a template, a clamping frame, and a sensing frame. The clamping frame is fixed to the side of the column, and the clamping frame is used to fix the template so that the curve track on the side of the template is vertically fixed outside the side of the column. The sensing frame is fixed to the moving base, and a photoelectric sensor is fixed to the sensing frame. The photoelectric sensor corresponds to the curve track of the template. The control system receives the signal of the photoelectric sensor and controls the movement of the moving base.

[0023] As can be seen from the above description of the structure of the present utility model, compared with the prior art, the present utility model has the following advantages: When the stone to be cut is solid, the fixing screw can be removed from the turntable, and then the stone is placed on the turntable. After that, the swing beam is swung to be fixed relative to the lifting beam so that the ejector pin corresponds to the rotation axis of the turntable. Then, the lifting beam is controlled to descend until the ejector pin presses against the solid stone, so that the solid stone can be fixed on the turntable and rotate relative to the saw blade as the turntable rotates. When the stone to be cut is hollow, the fastening screw can be fixed on the turntable first. Then, after the hollow position of the stone passes through the fastening screw, the fastening plate is screwed downward against the hollow stone, so that the hollow stone is also fixed on the turntable and rotates relative to the saw blade as the turntable rotates. Thus, it can be seen that the present utility model can clamp the upper and lower ends of the stone between the turntable and the ejector pin or between the turntable and the fastening plate, which is more stable than the method of only fixing the bottom of the stone, enabling the stone to rotate stably without easily falling off.

[0037] In addition, in the present application, orientation terms such as "upper" and "lower" are defined relative to the orientation in which the components in the accompanying drawings are schematically placed. It should be understood that these directional terms are relative concepts, and they are used for relative description and clarification, and they can change accordingly with the change of the orientation in which the components in the accompanying drawings are placed.

[0038] What the present utility model discloses is a vertical profiling stone cutting machine. As shown in the attached drawings Figures 1 to 3 , the stone cutting machine includes a base 1, a turntable 2, a tightening device 3, a pressing device 4, and a cutting device 5. Among them, a column 11 is fixed on one side of the base 1, the turntable 2 is located on the other side of the base 1, the pressing device 4 is arranged on the turntable 2, and both the tightening device 3 and the cutting device 5 are arranged on the column 11. The turntable 2 is used to place the stone to be cut. The specific stone to be cut can be a hollow stone or a solid stone, and the turntable 2 is driven by a rotating motor fixed in the base 1 to drive the stone to rotate.

[0039] Referring to the attached drawings again Figure 3 and 11 , the pressing device 4 includes a fastening screw 41 and a fastening plate 42. The bottom of the fastening screw 41 is fixedly connected with a connecting seat 411, and the connecting seat 411 is annularly distributed with connecting holes. The fastening plate 42 is screwed on the fastening screw 41. A plurality of threaded holes are annularly distributed on the upper surface of the turntable 2, and each threaded hole is adapted to be screwed and fixed with a fixing bolt (not shown in the attached drawings). When the stone to be cut is hollow, the connecting seat 411 is placed on the turntable 2 so that each of the connecting holes and each of the threaded holes correspond one by one, and then the fixing bolt is passed through the connecting hole and screwed with the threaded hole to press the connecting seat 411 on the turntable 2, so that the fastening screw 41 is fixed on the turntable 2; then the hollow part of the stone 7 is vertically passed through the fastening screw 41, and then the fastening plate 42 is pressed downward against the stone 7 to fix the stone 7 on the turntable 2.

[0040] Continuing to refer to the attached drawings Figure 1 and 2, the clamping device 3 includes a lifting beam 31, a swing beam 32 and a thimble 33. One end of the lifting beam 31 is connected to the column 11, and the lifting beam 31 is restricted to move up and down relative to the column 11. In this embodiment, the way to restrict lifting or lateral movement can be achieved by setting the connection structure of the dovetail slide rail and the slider. The lifting beam 31 fixes the first nut seat 353, the first motor 351 is fixed on the column 11, and a vertical first lead screw 352 is arranged inside the column 11. The first lead screw 352 is fixed to the output end of the first motor 351, and while passing through the first nut seat 353, the first lead screw 352 is in screw connection with the first nut seat 353. During operation, the first motor 351 drives the first lead screw 352 to rotate, and drives the lifting beam 31 to vertically move up and down relative to the turntable 2 along the column 11 through the transmission of the first nut seat 353.

[0041] One end of the swing beam 32 is provided with the thimble 33, and the other end of the swing beam 32 is hinged to the lifting beam 31, so that the lifting beam 31 can drive the swing beam 32 and the thimble 33 to move up and down relative to the turntable 2 along the column 11. As shown in the appendix Figure 4 As shown, the clamping device 3 further includes a positioning sleeve 341, a positioning seat 342 and a positioning pin 343. The positioning sleeve 341 is fixed to the side surface of the connecting end of the lifting beam 31 and the swing beam 32, the positioning seat 342 is fixed to the swing beam 32, and both the positioning sleeve 341 and the positioning seat 342 are provided with through holes vertically penetrating. When the swing beam 32 swings relative to the lifting beam 31 until the thimble 33 corresponds to the rotation axis of the turntable 2, the through holes of the positioning sleeve 341 and the positioning seat 342 correspond. At this time, passing the positioning pin 343 through the through holes of the positioning sleeve 341 and the positioning seat 342 can fix the swing beam 32 relative to the lifting beam 31, and at the same time, the thimble 33 remains corresponding to the rotation axis of the turntable 2. When the stone to be cut is solid, the stone is placed on the turntable 2. After the swing beam 32 swings relative to the lifting beam 31 to be fixed by passing the positioning pin 343 through the through holes of the positioning sleeve 341 and the positioning seat 342 in the above way, by controlling the lowering of the lifting beam 31, the thimble 33 can be lowered to press against the solid stone, so as to press and fix the solid stone on the turntable 2.

[0042] The way the thimble 33 is connected to the swing beam 32 can be as shown in the appendix Figure 5 and 6As shown, the jacking box 36, the slide 37, the ejector pin 33, the nut cover 371 and the adjusting screw 38 are connected by the end of the swing beam 32 away from the lifting beam 31. The jacking box 36 is fixed to the end of the swing beam 32, and the jacking box 36 is spirally inserted and fixed with a plurality of limit pins 361 from the outside to the inside. The slide 37 is adapted to fit in the jacking box 36, and a concave limit groove 372 is provided on the side of the slide 37. The limit groove 372 is a vertically arranged long strip groove. Each limit pin 361 is adapted to be inserted into the limit groove 372. The structure that the limit pin 361 is inserted into the limit groove 372 restricts the slide 37 to only be vertically lifted and lowered relative to the jacking box 36 in the jacking box 36.

[0043] The lower end of the slide 37 extends out of the jacking box 36 and is connected to a rotatable bearing sleeve 39, and the ejector pin 33 is fixed to the lower end of the bearing sleeve 39. The bearing sleeve 39 can be embedded with a bearing, and the bottom of the slide 37 is a connecting column 373, which penetrates and is fixed to the inner ring of the bearing in the bearing sleeve 39, thereby limiting the ejector pin 33 at the bottom of the bearing sleeve 39 to rotate only relative to the slide 37, so that when the turntable 2 drives the solid stone to rotate, the ejector pin 33 can press the stone and rotate with the rotation of the stone. In addition, the upper end of the slide 37 is fixed with a nut cover 371, and the lower end of the adjusting screw 38 passes through the top tightening box 36 from top to bottom, and then spirally penetrates into the nut cover 371 to the slide 37, and the adjusting screw 38 is also limited to be able to rotate only relative to the top tightening box 36. Specifically, an end cover 362 can be fixed on the upper end of the top tightening box 36, and the end cover 362 fixes the bearing. After the adjusting screw 38 passes through the bearing of the end cover 362, it spirally penetrates into the nut cover 371. The adjusting screw 38 is equipped with retaining springs at both the upper and lower ends of the bearing of the end cover 362, so that the adjusting screw 38 is limited to be sleeved in the bearing of the end cover 362 and can only rotate relative to the top tightening box 36. Preferably, the upper end of the adjusting screw 38 is located outside the top tightening box 36, and a hand wheel 381 can also be fixed. When the lifting beam 31 drives the swinging beam 32 and the tightening box 36 to descend until the ejector pin 33 presses against the solid stone, the adjusting screw 38 can be rotated by turning the hand wheel 381 to drive the slide 37 and the ejector pin 33 at the bottom of the slide 37 to rise and fall relative to the tightening box 36, so as to adjust the degree to which the ejector pin 33 presses the solid stone.

[0044] As attached Figure 7 and 8 As shown, the cutting device 5 includes a moving seat 51, a cutting motor 52, a spindle box 53 and a driving shaft (not shown in the drawings). The moving seat 51 is connected to the column 11 and moves relative to the column 11. The cutting motor 52 and the spindle box 53 are both fixed to the moving seat 51. The driving shaft passes through the spindle box 53, and the driving shaft is limited to only rotate relative to the spindle box 53. One end of the driving shaft is connected to the cutting motor 52 by belt drive or chain drive, and the other end of the driving shaft is installed with a fixed saw blade 54, so that the cutting motor 52 drives the saw blade 54 to rotate.

[0045] Further, in combination with the attached Figure 1 and 2 , a front slide plate 55 is arranged in front of the column 11. The front slide plate 55 is restricted to vertically lift relative to the column 11. The moving seat 51 is arranged on the front slide plate 55, so that when the front slide plate 55 lifts relative to the column 11, the moving seat 51 and the saw blade 54 are driven to lift relative to the column 11. The front slide plate 55 fixes a second nut seat 563, the second motor 561 is fixed on the column 11, a vertical second lead screw 562 is arranged inside the column 11, the second lead screw 562 is fixed to the output end of the second motor 561, and the second lead screw 562 passes through the second nut seat 563 and is in threaded connection with the second nut seat 563 at the same time. During operation, the second motor 561 drives the second lead screw 562 to rotate, and drives the lifting beam 31 to vertically lift relative to the turntable 2 along the column 11 through the transmission of the second nut seat 563.

[0046] Furthermore, the moving seat 51 is restricted to horizontally move relative to the front slide plate 55. The front slide plate 55 fixes a third nut seat 573, the end of the moving seat 51 fixes a third motor 571, a horizontal third lead screw 572 is arranged inside the moving seat 51, the third lead screw 572 is fixed to the output end of the third motor 571, and the third lead screw 572 passes through the third nut seat 573 and is in threaded connection with the third nut seat 573 at the same time. During operation, the third motor 571 drives the third lead screw 572 to rotate, and drives the front slide plate 55 to horizontally move relative to the turntable 2 along the column 11 through the transmission of the third nut seat 573.

[0047] As shown in the attached Figures 9 to 11 , the profiling control device includes a template 61, a clamping frame 62 and a sensing frame 63. Among them, a curve track is arranged on one vertical side of the template 61. The clamping frame 62 is fixed on the side of the column 11, and the clamping frame 62 is used to fix the template 61. The fixing method can be that the clamping frame 62 has a clamping rod 621 with a C-shaped cross section. A plurality of threaded holes are arranged on the side of the clamping rod 621, and the threaded holes are adapted to be in threaded connection with fixing bolts. One edge of one side of the template 61 is a curve track for profiling, and the other edge of the other side of the template 61 is a vertical edge. After the set edge is inserted into the clamping rod 621, the fixing bolt is screwed into the clamping rod to press and fix the template 61, so that the curve track of the template 61 can be vertically fixed outside the side of the column 11. The sensing frame 63 is fixed to the moving seat 51, and a photoelectric sensor (not shown in the attached drawing) is fixed on the sensing frame 63, and the photoelectric sensor corresponds to the outside of the curve track of the template 61. In addition, the present invention further includes a control system, and the control system can be a PLC controller, which is used to control the operation of each motor and can be used to receive the signal control of the photoelectric sensor to control the operation of each motor.

[0048] During specific operation, the second motor 561 drives the front slide plate 55 to lift and lower, driving the moving seat 51 to move vertically relative to the template 61 on one side of the column 11, so that the photoelectric sensor on the side of the moving seat 51 senses the edge trajectory of the curve of the template 61 from top to bottom, and sends the sensing signal to the control system in real time. The control system controls the third motor 571 to rotate forward or reverse accordingly, driving the moving seat 51 to move left and right, thereby driving the saw blade 54 on the other side of the moving seat 51 to move accordingly. It can realize tracking and copying the curve trajectory of the template 61 while driving the saw blade 54 to cut the stone 7 along the same path as the curve trajectory of the template 61, so as to cut the stone 7 into a columnar body with an outer diameter edge consistent with the edge trajectory of the template 61.

[0049] In summary, when the stone to be cut is solid, the fixing screw can be removed from the turntable 2, and then the stone is placed on the turntable 2. After that, the swing beam 32 is swung to be fixed relative to the lifting beam 31 so that the ejector pin 33 corresponds to the rotation axis of the turntable 2. Then, the lifting beam 31 is controlled to descend until the ejector pin 33 presses against the solid stone, and the solid stone can be fixed on the turntable 2 and rotate relative to the saw blade 54 as the turntable 2 rotates. When the stone to be cut is hollow, the fastening screw 41 can be fixed on the turntable 2 first. After the hollow position of the stone passes through the fastening screw 41, the fastening plate 42 is screwed downward against the hollow stone, and the hollow stone is also fixed on the turntable 2 and rotates relative to the saw blade 54 as the turntable 2 rotates. It can be seen that the utility model can clamp the upper and lower ends of the stone between the turntable 2 and the ejector pin 33 or between the turntable 2 and the fastening plate 42, which is more stable than the method of only fixing the bottom of the stone. The stone rotates stably relative to the turntable 2 as the turntable 2 rotates and will not easily fall off, so that the saw blade 54 can stably cut the fixed stone along the specified path. Moreover, the utility model can be used for fixing and processing both hollow stones and solid stones, with good applicability.

[0050] The above is only the specific implementation manner of the utility model, but the design concept of the utility model is not limited thereto. Any non-substantial modification of the utility model using this concept shall fall within the scope of infringement of the protection scope of the utility model.

The sensing frame is fixed to the moving seat, and a photoelectric sensor is fixed on the sensing frame. The photoelectric sensor corresponds to the curved track of the template. The control system receives the signal of the photoelectric sensor and controls the movement of the moving seat.
