[0010] As a further solution of the present invention, the pushing assembly includes a dual-axis motor and two groups of rotating shafts, and the number of rotating shafts in each group is two, one end of the rotating shaft is rotatably connected to one side of the inner wall of the groove, the dual-axis motor is fixed to one side of the frame, and the two output shafts of the dual-axis motor are fixedly connected to a connecting shaft, and the other end of the connecting shaft is fixed to a transmission mechanism, and the transmission mechanism is rotatably connected to the back of the frame through a shaft sleeve, and the transmission mechanism consists of two pulleys and a belt, and the belt is sleeved on the outside of the two pulleys, one side of the lower pulley is fixed to the end of the connecting shaft, and one side of the upper pulley is fixed to the end of one of the rotating shafts.

[0011] As a further solution of the present invention, a second transmission belt is provided in the groove, and second transmission wheels are respectively sleeved on both sides of the inside of the second transmission belt. The rotating shaft passes through and is fixed in the middle of the second transmission wheel, and a slider is fixedly connected to one side of the bottom of the second transmission belt.

[0012] As a further solution of the present invention, two brackets are provided below the second transmission belt, and sliding rods are fixed on both sides of the opposite surfaces of the two brackets. The sliding holes inside the sliders are slidably connected to the outer walls of the sliders. Two fixed rods are fixed between the two sliders, and push blocks are sliding through the outside of the two fixed rods. The push blocks are L-shaped and the lowest end of the push blocks is higher than the turntable. A blanking plate is fixed on the side of the frame away from the push block, and the blanking plate is designed to be tilted downward.

[0013] A method for using a positioning and trimming device for processing building stones, the method comprising the following steps:

[0014] When in use, the two electric hydraulic telescopic rods are controlled to retract so as to drive the slide to move upward, and the slide drives the two saw discs to move upward through the cutting machine and the drive shaft, so that the two saw discs are located above the frame as a whole, and the building stone to be cut is placed on the turntable, and one of the first transmission wheels is driven to rotate by rotating the turn handle. Since the two first transmission wheels are connected by the first transmission belt, the two bidirectional screw rods on one side of the two first transmission wheels rotate synchronously, and at the same time, the corresponding two columns respectively drive the cross plates to approach each other, and the columns are limited and guided by the limit rods to improve the stability of the horizontal movement of the cross plates driven by the columns, so that the two cross plates drive the two clamping plates to clamp the front and back sides of the stone, thereby achieving the purpose of positioning the stone;

[0015] When trimming the stone on the turntable, the cutting machine is controlled to work so that the two output shafts at the bottom of the cutting machine respectively drive the drive shafts to rotate. The two drive shafts drive the two saw discs to work synchronously through the adjustment components. Secondly, the two electric hydraulic telescopic rods are controlled to extend and drive the slide to slide inside the two slide grooves. The slide is limited by the slide groove to improve the stability of the slide driving the cutting machine to move downward and the cutting work. The two saw discs trim the two sides of the stone during the downward movement. When trimming the two clamping surfaces of the stone, the two electric hydraulic telescopic rods are controlled to retract. The first movement of the handle is to retract, causing the slide to drive the cutting machine to move upward, and then the handle is rotated in the opposite direction, causing the first transmission belt to drive the bidirectional screw to rotate in the opposite direction. Similarly, the two corresponding columns respectively drive the cross plates to move away from each other, causing the cross plates to drive the splints away from the stone. The servo motor is then controlled to work, causing the output shaft of the servo motor to drive the stone to rotate ninety degrees through the turntable. During this process, the surface to be trimmed is adjusted to the front and rear sides of the turntable, and the two surfaces to be trimmed are located on the left and right sides of the turntable. Next, the handle is rotated forward, and similarly, the two cross plates drive the two splints to clamp the stone, and the splints are in contact with the surface after trimming.

[0016] When the stone is trimmed again, if the length and width of the stone are different, the distance between the two saw discs needs to be adjusted. The fastening screw on the limit block is loosened to disengage the fastening screw from the slot, thereby releasing the locking state of the saw disc, allowing the saw disc to drive the sliding sleeve to slide outside the drive shaft, and the sliding sleeve drives the internal limit block to move inside the limit slot, and the limit block is limited and guided by the limit slot to keep the saw disc moving horizontally, thereby improving the stability of the synchronous rotation of the saw disc driven by the drive shaft. After adjusting the saw disc to the appropriate position, the fastening screw is tightened so that the fastening screw is stuck in one of the slots to achieve the purpose of locking the sliding sleeve and the saw disc position. Similarly, the saw disc on the other side is operated, and the distance between the two saw discs can meet the requirements of double-sided synchronous trimming of stones of different specifications. After starting the cutting machine, the two electric hydraulic telescopic rods are controlled to extend, so that the slide drives the two saw discs through the cutting machine to trim the stone;

[0017] After completing the trimming work on multiple surfaces of the stone, the cutting machine and the saw disc are adjusted to above the stone, and the handle is rotated in the opposite direction to separate the two splints from the front and back sides of the stone. The dual-axis motor is started, so that the two output shafts of the dual-axis motor respectively drive the two connecting shafts to rotate, and the connecting shaft drives the rotating shaft to rotate through the transmission mechanism, and the rotating shaft drives the second transmission wheel to rotate. Since the two second transmission wheels on the same side are outer-mounted with the second transmission belt, the second transmission belts on both sides of the groove will work synchronously, and the bottom of the two second transmission belts respectively drive the two fixed rods to move to the left through the slider. Since the sliding hole inside the slider is slidably connected to the outer wall of the sliding rod, the sliding rod limits the slider, thereby improving the stability of the horizontal movement of the push block driven by the fixed rod. In the process of the push block moving to the left, it will push the stone to the left until the stone is pushed into the blanking plate on one side of the frame. Since the blanking plate is tilted downward, it is convenient to send the stone out of the frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention operates the positioning assembly to enable the two horizontal plates to drive the two clamping plates to clamp the front and rear sides of the stone, thereby achieving the purpose of positioning the stone. Secondly, the two electric hydraulic telescopic rods are controlled to extend and the cutting machine is driven downward by the slide. The two saw discs perform synchronous trimming on both sides of the stone during the downward movement. When trimming the two clamping surfaces of the stone, the two electric hydraulic telescopic rods are controlled to retract, so that the slide drives the cutting machine upward. The positioning assembly is then operated to release the locking state of the stone. The output shaft of the servo motor drives the stone to rotate ninety degrees through the turntable. During this process, the surface where the trimming is completed is adjusted to the front and rear sides of the turntable, and the two surfaces to be trimmed are located on the left and right sides of the turntable. If the length and width of the stone are different, the distance between the two saw discs needs to be adjusted. By loosening the fastening screw on the limit block, the fastening screw is disengaged from the slot, thereby releasing the locking state of the saw disc, allowing the saw disc to drive the sliding sleeve to slide outside the drive shaft. After adjusting the saw disc to the appropriate position, tighten the fastening screw so that the fastening screw is stuck in one of the slots, thereby locking the sliding sleeve and the saw disc position. Similarly, the saw disc on the other side is operated. By changing the spacing between the two saw discs, the needs of double-sided synchronous trimming of stones of different specifications can be met. The processing surface of the stone can be quickly switched and adjusted, and the stone can be prevented from shifting, ensuring the trimming accuracy, which is conducive to efficient and stable trimming operations of building stones.

[0020] 2. The present invention drives one of the first transmission wheels to rotate by rotating the handle. Since the two first transmission wheels are connected by the first transmission belt, the two bidirectional screw rods on one side of the two first transmission wheels rotate synchronously. At the same time, the corresponding two columns respectively drive the cross plates to approach each other, so that the two cross plates drive the two clamping plates to clamp the front and back sides of the stone, thereby achieving the purpose of positioning the stone. The handle is rotated in the opposite direction, so that the first transmission belt drives the bidirectional screw rods to rotate in the opposite direction. Similarly, the corresponding two columns respectively drive the cross plates to move away from each other, so that the cross plates drive the clamping plates away from the stone, thereby achieving the purpose of quickly locking and unlocking the stone, thereby improving the convenience of operation. Moreover, since the two clamping plates are simultaneously The stone is pushed to the middle of the turntable by the step-by-step movement, so as to facilitate the subsequent precise cutting of the stone. When the stone on the turntable is removed, the two output shafts of the dual-axis motor respectively drive the two connecting shafts to rotate, and the connecting shaft drives the rotating shaft to rotate through the transmission mechanism, and the rotating shaft drives the second transmission wheel to rotate, so that the second transmission belts on both sides of the groove will work synchronously. The bottom of the two second transmission belts respectively drives the two fixed rods to move to the left through the sliders. The process of the push block moving to the left will push the stone to the left until the stone is pushed onto the blanking plate with an inclined design on one side of the frame, which makes it easy to move the stone out of the frame, thereby reducing the workload and facilitating the next edge cutting of the stone.

The slide 4 is limited by the slide grooves 5, thereby improving the stability of the slide 4 driving the cutting machine 6 to move downward and the cutting operation;

[0036] A cutting machine 6 is fixedly installed on the bottom of the slide 4, and a driving shaft 7 is fixed on the two output shafts at the bottom of the cutting machine 6. An adjusting component 11 is sleeved on the outside of the driving shaft 7, and a saw disk 10 is fixedly connected to the outer wall of the adjusting component 11. A turntable 13 is provided between the two saw disks 10. The bottom end of the turntable 13 is rotatably connected to the middle of the frame 1 through a shaft sleeve, and the bottom end of the turntable 13 passes through the middle of the frame 1 and is fixedly connected to a servo motor 12. The servo motor 12 is fixedly installed on the bottom of the frame 1, and the output shaft of the servo motor 12 drives the stone to rotate ninety degrees through the turntable 13. In this process, the surface to be trimmed is adjusted to the front and rear sides of the turntable 13, and the two surfaces to be trimmed are located on the left and right sides of the turntable 13, which is convenient for quickly switching and adjusting the processing surface of the stone.

[0037] Positioning components 14 are provided on the front and rear sides of the turntable 13. The positioning components 14 are installed through the frame 1. Two limit rods 15 are fixed on both sides of the inside of the frame 1. The two limit rods 15 on the same side slide through one side of the bottom of the positioning component 14. Grooves 16 are respectively provided on both sides of the upper part of the frame 1. Pushing components 17 are provided in the two grooves 16. The bottom of the pushing component 17 is installed on one side of the inside of the frame 1.

[0038] As a further solution of the present invention, the adjustment assembly 11 includes a sleeve 111, which is slidably connected to the outside of the drive shaft 7. The inner wall of the sleeve 111 is fixedly connected to a limit block 112. A limit slot 8 is provided on the drive shaft 7. A plurality of slots 9 are provided at equal intervals at the bottom of the limit slot 8. The limit block 112 is slidably connected to the limit slot 8. A fastening screw 113 is threadedly connected to one side of the sleeve 111. The bottom end of the fastening screw 113 is clamped in one of the slots 9.

[0039] During operation, the fastening screw 113 on the limit block 112 is loosened to disengage the fastening screw 113 from the card slot 9, thereby releasing the locking state of the saw disc 10, and the saw disc 10 drives the sliding sleeve 111 to slide freely outside the drive shaft 7, so that the position of the saw disc 10 can be freely adjusted;

[0040] The sliding sleeve 111 drives the internal limiting block 112 to move inside the limiting groove 8, and the limiting groove 8 limits and guides the limiting block 112, so that the saw disk 10 keeps moving horizontally, thereby improving the stability of the synchronous rotation of the saw disk 10 driven by the drive shaft 7;

[0041] After adjusting the saw disc 10 to the appropriate position, tighten the fastening screw 113 so that the fastening screw 113 is locked in one of the slots 9, thereby locking the position of the sleeve 111 and the saw disc 10, preventing the saw disc 10 from shaking during operation, and thereby improving the stability of the saw disc 10 in cutting.

[0042] As a further embodiment of the present invention, the positioning assembly 14 includes two horizontal plates 141 , with clamping plates 142 fixed to opposite surfaces of the two horizontal plates 141 , and vertical columns 143 fixed to both sides of the bottom of the horizontal plates 141 , respectively. The limiting rod 15 passes through and slides in the two vertical columns 143 on the same side.

[0043] During operation, the two corresponding upright posts 143 drive the horizontal plate 141 to move closer to each other, and the upright posts 143 are limited and guided by the limiting rods 15 to improve the stability of the horizontal movement of the horizontal plate 141 driven by the upright posts 143 .

[0044] As a further solution of the present invention, a bidirectional screw rod 144 is provided above the limit rod 15. The bidirectional screw rod 144 is threadedly connected to the two columns 143 on the same side, and the two sides of the outside of the bidirectional screw rod 144 are rotatably connected to the frame 1 through shaft sleeves. One end of the bidirectional screw rod 144 passes through the frame 1 and is fixed with a first transmission wheel 145. The outer surfaces of the two first transmission wheels 145 are connected with the same first transmission belt 146, and a rotating handle 147 is fixed to one side of one of the first transmission wheels 145.

[0045] During operation, one of the first transmission wheels 145 is driven to rotate by rotating the handle 147. Since the two first transmission wheels 145 are connected by the first transmission belt 146, the two bidirectional screw rods 144 on one side of the two first transmission wheels 145 rotate synchronously, thereby facilitating the synchronous adjustment of the column 143, the cross plate 141 and the splint 142 on the bidirectional screw rod 144, thereby improving the stability of the splint 142 in clamping the stone.

[0046] As a further solution of the present invention, the pusher assembly 17 includes a dual-axis motor 171 and two groups of rotating shafts 174, and the number of each group of rotating shafts 174 is two, one end of the rotating shaft 174 is rotatably connected to one side of the inner wall of the groove 16, the dual-axis motor 171 is fixed to one side of the frame 1, and the two output shafts of the dual-axis motor 171 are fixedly connected to the connecting shaft 172, and the other end of the connecting shaft 172 is fixed to the transmission mechanism 173, which is rotatably connected to the back of the frame 1 through a shaft sleeve. The transmission mechanism 173 consists of two pulleys and a belt. The belt is sleeved on the outside of the two pulleys, one side of the lower pulley is fixed to the end of the connecting shaft 172, and one side of the upper pulley is fixed to the end of one of the rotating shafts 174;

[0047] During operation, the two output shafts of the dual-axis motor 171 respectively drive the two connecting shafts 172 to rotate, and the connecting shaft 172 drives the rotating shaft 174 to rotate through the transmission mechanism 173. The rotating shaft 174 drives the second transmission wheel 175 to rotate. Since the two second transmission wheels 175 on the same side are outer-engaged with the second transmission belt 176, the second transmission belts 176 on both sides of the groove 16 will operate synchronously.

[0048] As a further embodiment of the present invention, a second transmission belt 176 is provided in the groove 16. Second transmission wheels 175 are respectively sleeved on both sides of the interior of the second transmission belt 176. A rotating shaft 174 is fixedly connected to the middle of the second transmission wheel 175. A slider 179 is fixedly connected to one side of the bottom of the second transmission belt 176. Two brackets 178 are provided below the second transmission belt 176. Slide rods 177 are respectively fixed on both sides of the opposing surfaces of the two brackets 178. The sliding holes in the sliders 179 are slidably connected to the outer walls of the sliders 177. Two fixing rods 1791 are fixed between the two sliders 179.

[0049] During operation, the bottom of the two second transmission belts 176 drive the two fixed rods 1791 to move to the left through the slider 179 respectively. Since the sliding hole inside the slider 179 is slidably connected to the outer wall of the sliding rod 177, the sliding rod 177 limits the slider 179, thereby improving the stability of the horizontal movement of the push block 1792 driven by the fixed rod 1791.

[0050] A push block 1792 is slidably passed through the outside of the two fixed rods 1791. The push block 1792 is L-shaped and the lowest end of the push block 1792 is higher than the turntable 13. A blanking plate 18 is fixed to the side of the frame 1 away from the push block 1792. The blanking plate 18 is tilted downward.

[0051] During operation, the pushing block 1792 will push the stone to move to the left as it moves to the left, until the stone is pushed onto the drop plate 18 with an inclined design on one side of the frame 1, making it easier to move the stone out of the frame 1 and improving the convenience of the unloading operation.

[0052] A method for using a positioning and trimming device for processing building stones, the method comprising the following steps:

[0053] When in use, the two electric hydraulic telescopic rods 3 are controlled to contract so as to drive the slide 4 to move upward, and the slide 4 drives the two saw discs 10 to move upward through the cutting machine 6 and the driving shaft 7, so that the two saw discs 10 are located above the frame 1 as a whole, and the building stone to be cut is placed on the turntable 13, and one of the first transmission wheels 145 is driven to rotate by rotating the handle 147. Since the two first transmission wheels 145 are connected by the first transmission belt 146, the two bidirectional screw rods 144 on one side of the two first transmission wheels 145 rotate synchronously. At the same time, the corresponding two columns 143 respectively drive the cross plates 141 to approach each other, and the limit rod 15 is used to limit and guide the columns 143, thereby improving the stability of the horizontal movement of the cross plates 141 driven by the columns 143, so that the two cross plates 141 drive the two clamping plates 142 to clamp the front and back sides of the stone, thereby achieving the purpose of positioning the stone;

[0054] When trimming the stone on the turntable 13, the cutting machine 6 is controlled to work so that the two output shafts at the bottom of the cutting machine 6 respectively drive the drive shaft 7 to rotate, and the two drive shafts 7 drive the two saw discs 10 to work synchronously through the adjustment component 11. Secondly, the two electric hydraulic telescopic rods 3 are controlled to extend and drive the slide 4 to slide inside the two slide grooves 5. The slide 4 is limited by the slide groove 5 to improve the stability of the slide 4 driving the cutting machine 6 to move downward and the cutting work. The two saw discs 10 trim the two sides of the stone during the downward movement. When trimming the two clamping surfaces of the stone, the two electric hydraulic telescopic rods 3 are controlled to shrink so that the slide 4 drives the cutting machine 6 upward. Then, the handle 147 is rotated in the opposite direction, so that the first transmission belt 146 drives the bidirectional screw rod 144 to rotate in the opposite direction. Similarly, the two corresponding columns 143 respectively drive the cross plates 141 to move away from each other, so that the cross plates 141 drive the clamping plates 142 away from the stone. Then, the servo motor 12 is controlled to work, so that the output shaft of the servo motor 12 drives the stone to rotate ninety degrees through the turntable 13. In this process, the surface to be trimmed is adjusted to the front and rear sides of the turntable 13, and the two surfaces to be trimmed are located on the left and right sides of the turntable 13. Then, the handle 147 is rotated in the forward direction. Similarly, the two cross plates 141 drive the two clamping plates 142 to clamp the stone, and the clamping plates 142 are in contact with the surface after trimming.

[0055] When the stone is trimmed again, if the length and width of the stone are different, the distance between the two saw discs 10 needs to be adjusted. By loosening the fastening screw 113 on the limit block 112, the fastening screw 113 is disengaged from the card slot 9, thereby releasing the locking state of the saw disc 10, so that the saw disc 10 drives the sliding sleeve 111 to slide outside the drive shaft 7, and the sliding sleeve 111 drives the internal limit block 112 to move inside the limit slot 8. The limit block 112 is limited and guided by the limit slot 8, so that the saw disc 10 keeps moving horizontally, improving the drive shaft 7 drives the saw disc 10 to rotate synchronously to ensure stability. After adjusting the saw disc 10 to a suitable position, tighten the fastening screw 113 so that the fastening screw 113 is locked in one of the slots 9 to achieve the purpose of locking the position of the sliding sleeve 111 and the saw disc 10. Similarly, operate the saw disc 10 on the other side. By changing the spacing between the two saw discs 10, the demand for double-sided synchronous trimming of stones of different specifications can be met. After starting the cutting machine 6, control the two electric hydraulic telescopic rods 3 to extend so that the slide 4 drives the two saw discs 10 to trim the stone through the cutting machine 6.

[0056] After completing the trimming work on multiple surfaces of the stone, the cutting machine 6 and the saw disc 10 are adjusted to the top of the stone, and the handle 147 is rotated in the opposite direction to separate the two clamping plates 142 from the front and back sides of the stone. The dual-axis motor 171 is started, and the two output shafts of the dual-axis motor 171 respectively drive the two connecting shafts 172 to rotate. The connecting shaft 172 drives the rotating shaft 174 to rotate through the transmission mechanism 173, and the rotating shaft 174 drives the second transmission wheel 175 to rotate. Since the two second transmission wheels 175 on the same side are outer-mounted with the second transmission belt 176, the second transmission wheels 175 on both sides of the groove 16 are rotated. The transmission belt 176 will work synchronously, and the bottom of the two second transmission belts 176 will drive the two fixed rods 1791 to move to the left through the slider 179 respectively. Since the sliding hole inside the slider 179 is slidably connected to the outer wall of the slider 177, the slider 177 limits the slider 179, thereby improving the stability of the horizontal movement of the push block 1792 driven by the fixed rod 1791. During the movement of the push block 1792 to the left, it will push the stone to move to the left until the stone is pushed onto the blanking plate 18 on one side of the frame 1. Since the blanking plate 18 is designed to be tilted downward, it is convenient to send the stone out of the frame 1.

Since the two first transmission wheels (145) are connected to the first transmission belt (1 46) are connected, so that the two bidirectional screw rods (144) on one side of the two first transmission wheels (145) rotate synchronously, and at the same time, the corresponding two columns (143) respectively drive the cross plates (141) to approach each other, and the column (143) is limited and guided by the limit rod (15), thereby improving the stability of the horizontal movement of the cross plates (141) driven by the column (143), so that the two cross plates (141) drive the two clamping plates (142) to clamp the front and back sides of the stone, thereby achieving the purpose of positioning the stone; When the stone on the turntable (13) is trimmed, the cutting machine (6) is controlled to work so that the two output shafts at the bottom of the cutting machine (6) respectively drive the driving shaft (7) to rotate. The two driving shafts (7) drive the two saw discs (10) to work synchronously through the adjustment component (11). Then, the two electric hydraulic telescopic rods (3) are controlled to extend and drive the slide (4) to slide inside the two slide grooves (5). The slide (4) is limited by the slide grooves (5) to improve the stability of the slide (4) driving the cutting machine (6) to move downward and the cutting work.

When trimming the two clamping surfaces of the stone, the two electric hydraulic telescopic rods (3) are controlled to contract so that the slide (4) drives the cutting machine (6) to move downward. ) moves up, and then the handle (147) is rotated in the opposite direction, so that the first transmission belt (146) drives the bidirectional screw rod (144) to rotate in the opposite direction. Similarly, the two corresponding columns (143) respectively drive the transverse plates (141) to move away from each other, so that the transverse plates (141) drive the clamping plates (142) away from the stone. Then the servo motor (12) is controlled to work, so that the output shaft of the servo motor (12) drives the stone to rotate ninety degrees through the turntable (13). In this process, the surface to be trimmed is adjusted to the front and back sides of the turntable (13), and the two surfaces to be trimmed are located on the left and right sides of the turntable (13). Next, the handle (147) is rotated in the forward direction. Similarly, the two transverse plates (141) drive the two clamping plates (142) to clamp the stone, and the clamping plates (142) are in contact with the surface after trimming. When the stone is trimmed again, if the length and width of the stone are different, the distance between the two saw discs (10) needs to be adjusted. By loosening the fastening screw (113) on the limit block (112), the fastening screw (113) is disengaged from the slot (9), thereby releasing the locking state of the saw disc (10), so that the saw disc (10) drives the sliding sleeve (111) to slide outside the drive shaft (7), and the sliding sleeve (111) drives the internal limit block (112) to move inside the limit groove (8).

Similarly, the saw disc (10) on the other side is operated to meet the requirements of double-sided synchronous trimming of stones of different specifications by changing the spacing between the two saw discs (10). After starting the cutting machine (6), the two electric hydraulic telescopic rods (3) are controlled to extend so that the slide (4) drives the two saw discs (10) to trim the stone through the cutting machine (6); After completing the trimming of multiple faces of the stone, the cutting machine (6) and the saw disc (10) are adjusted to the top of the stone, the handle (147) is rotated in the opposite direction to separate the two clamping plates (142) from the front and rear sides of the stone, and the dual-axis motor (171) is started to drive the two output shafts of the dual-axis motor (171) to respectively drive the two connecting shafts (172) to rotate, and the connecting shaft (172) drives the rotating shaft (174) to rotate through the transmission mechanism (173), and the rotating shaft (174) drives the second transmission wheel (175) to rotate.
