Technical Field

[0001] The invention belongs to the technical field of grinding, in particular to a cylindrical building material grinding device. Background Art

[0002] Cylindrical building materials refer to various materials in the field of construction that are cylindrical in shape. A cylinder is a geometric body consisting of two equal-sized, parallel circles and a curved surface connecting the two bottom surfaces. These materials play different roles in building structure, decoration, etc. Cylindrical building materials include metal, stone, wood and concrete.

[0003] The cylindrical building material grinding device refers to a device or tool specially used for grinding the surface of cylindrical building materials. Its purpose is to make the surface of cylindrical building materials reach the expected smoothness, flatness or specific texture effect through grinding, polishing and other operations to meet the needs of construction or decoration.

[0004] A patent application with publication number CN112355732A discloses an injection mold, including a grinding rod that can form an overall uniform wrapping of the side arc surface of the rock specimen when rotating and grinding, so that the overall radial force on the side of the specimen is uniform, and the lower clamping column and the upper clamping column can synchronously and symmetrically clamp the two end surfaces of the rock specimen to make the axial force of the specimen uniform. This ensures that the specimen is not easily damaged, improves the success rate of production, and is not easy to damage the rock specimen during use. It is practical and efficient with a high success rate of production, and can grind and produce rock specimens with precise diameter size and smooth surface in one time, which lays the foundation for laboratory rock mechanics experiments and is of great significance to the prevention and control of mine disasters.

[0005] In the current existing technology, when grinding metal cylindrical building pipes, due to the curved shape of the pipe and the rotational movement during the grinding process, dust is more likely to spread into the air. Even if there is a dust suction system, the uncertainty of the direction and speed of dust generation may cause some dust to not be sucked away in time, thereby polluting the working environment and causing harm to the health of the operator.

[0009] The pipe is fixed on the fixing component, and then the moving component is controlled to drive the welding part of the pipe to calibrate the position with the grinding component in the working box. When the calibration of the two is completed, the grinding component is started to grind the welding surface of the pipe. While the grinding component is grinding, the dust collecting component collects the dust generated by the grinding component through the air outlet slot plate, so that the dust generated by the grinding component is collected in one place to prevent the uncertainty of the direction and speed of the dust generation, which leads to some dust not being sucked away in time, thereby polluting the working environment and causing harm to the health of the operator.

At this time, the plurality of pipe clamping blocks in the two shaft boxes support the inner wall of the pipe at both ends, thereby realizing the fixing of the pipe. By moving the plurality of pipe clamping blocks to fix the pipe, the device can be applied to the fixing of pipes of different diameters, thereby fixing the pipes of different diameters.

[0011] Preferably, the top of the support plate is slidably connected to a rectangular box, the inner wall of the rectangular box is slidably connected to a support seat, a tube rotating motor is fixedly installed on the top of the support seat, and the output end of the tube rotating motor is fixedly connected to one side of the trough box. When the pipe is fixed, the position of the welding part of the pipe that needs to be polished is aligned with the polishing assembly by controlling the moving part assembly. When the alignment of the two is completed, the tube rotating motor is controlled to drive the trough box to rotate, so that the tube rotating motor drives the pipe to rotate, which can speed up the polishing speed of the pipe and also enable the polishing assembly to polish the welding surface of the pipe more comprehensively.

[0012] Preferably, the moving component assembly includes a torque regulating motor, a shift box is fixedly installed at the bottom of the support plate, the torque regulating motor is fixedly installed on the inner wall of the shift box, a screw shaft is fixedly installed at the output end of the torque regulating motor, the outer wall of the screw shaft is threadedly connected with a shift plate, the top of the shift plate is fixedly connected to the bottom of the torque box, the outer wall of the shift plate is slidingly connected to the inner wall of the support plate, when the pipe is fixed, the screw shaft is driven to rotate by controlling the torque regulating motor in the shift box, and when the screw shaft rotates, the screw shaft is driven by the shift plate through the threaded transmission to drive the torque box to slide on the top of the support plate, so that the torque box pulls the pipe to move on the top of the support plate, thereby realizing the alignment of the welding point of the pipe and the grinding assembly, which plays a role in adjusting the alignment.

[0013] Preferably, the grinding assembly includes a connecting frame, the inner wall of the connecting frame is rotatably connected to a grinding shaft, a retaining frame is fixedly installed on one side of the connecting frame, a bidirectional motor is fixedly installed on one side of the retaining frame, one output end of the bidirectional motor is fixedly connected to one side of the grinding shaft, and the grinding shaft is placed on the upper side of the pipe. When the position of the pipe is corrected, the pipe rotating motor is controlled to drive the pipe to rotate, and at the same time, the bidirectional motor drives the grinding shaft to rotate. When the grinding shaft rotates, the grinding shaft grinds the welding part of the pipe to play a grinding role.

[0014] Preferably, a hydraulic cylinder is fixedly installed on the top of the working box, and the output end of the hydraulic cylinder is fixedly connected to the top of the connecting frame, and the outer wall of the connecting frame is slidably connected to the inner wall of the working box. When the pipe needs to be polished, the grinding shaft is driven to rotate by the bidirectional motor, and the hydraulic cylinder drives the grinding shaft downward through the connecting frame. When the grinding shaft contacts the welding part of the pipe, the pipe and the grinding shaft rotate in opposite directions, so that the grinding shaft polishes the welding part of the pipe. At the same time, the grinding shaft is driven to move downward continuously by the hydraulic cylinder, so that the grinding shaft can continuously polish the welding part of the pipe, thereby completing the polishing operation of the pipe welding position, which plays a role in controlling the feed of the grinding shaft.

[0015] Preferably, the dust collecting assembly also includes a shaft disc, which is fixedly mounted on the other side of the retaining frame, and an axial flow fan is fixedly mounted on the other output end of the bidirectional motor, the axial flow fan is placed inside the shaft disc, and an air outlet slot plate is fixedly mounted on one side of the connecting frame, and the air outlet slot plate is placed on the upper side of the grinding sand shaft, and an air flow pipe is fixedly connected between the air outlet slot plate and the shaft disc. When the bidirectional motor drives the grinding sand shaft to rotate to grind the pipe, the bidirectional motor also drives the axial flow fan to rotate. When the axial flow fan rotates, the axial flow fan will blow out airflow, and then pass through the axial flow With the continuous rotation of the fan, the airflow will enter the air outlet slot plate along the air flow pipe, and finally blow out from the bottom of the air outlet slot plate, so that when the grinding shaft grinds the pipe, the airflow blows out from the air outlet slot plate to blow the grinding part of the grinding shaft, thereby blowing the dust produced by the grinding shaft into the work box, preventing the uncertainty of the direction and speed of dust generation, resulting in some dust not being sucked away in time, and thus flying in the air, thereby polluting the working environment and causing harm to the health of the operator, and playing a role in preventing dust from floating out.

[0016] The two L-shaped toothed bars are respectively driven by the toothed bars to move upward and downward, thereby the two L-shaped toothed bars drive the two pipe support rods to move upward and the two pipe support rods support the pipe around the pipe, thereby preventing the pipe from being displaced due to the grinding strain pressure of the grinding shaft on the pipe during rotation, thereby affecting the grinding effect and playing the role of supporting the pipe support.

A push plate spring is arranged between the bottom of the slag blocking plate and the inner wall of the slag box, and pressure rods are symmetrically fixedly installed on the bottom of the connecting frame, and the bottom ends of the two pressure rods are placed directly above the slag blocking plate. When the hydraulic cylinder drives the grinding shaft to move downward for grinding through the connecting frame, the connecting frame also drives the pressure rod at its bottom to move downward. When the pressure rod moves downward, it pushes the slag blocking plate to squeeze the push plate spring to rotate in the slag box, thereby making the slag blocking plate open in the slag box and providing an entrance for the entry of dust. When the operation is completed, the hydraulic cylinder drives the grinding shaft to reset, and the push plate spring loses the squeezing of the pressure rod. Under the elastic push of the push plate spring, the slag blocking plate will rotate and close in the slag box, thereby closing the slag box and preventing the dust entering the slag box from drifting out of the slag box, thereby blocking the outflow of dust.

[0018] Preferably, an exhaust fan and a slag blocking plate are fixedly installed inside the slag box, and the exhaust fan is placed on one side of the slag blocking plate. When the air outlet slot plate blows the dust, the exhaust fan in the slag box performs exhaust operation, so that when the dust is blown into the working box by the air outlet slot plate, the exhaust fan draws the dust, so that the dust passes through the slag blocking plate and enters the slag box, playing a role in cooperating with the dust collection operation of the air outlet slot plate. The slag blocking plate is provided to block dust and prevent dust from contacting the slag box and affecting the exhaust operation of the slag box.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The cylindrical building material grinding device described in the present invention grinds the pipe by driving the grinding sand shaft to rotate when the bidirectional motor drives the axial flow fan to rotate. When the axial flow fan rotates, the axial flow fan will blow out airflow, and then through the continuous rotation of the axial flow fan, the airflow will enter the air outlet slot plate along the airflow pipe, and finally blow out from the bottom of the air outlet slot plate, so that when the grinding sand shaft grinds the pipe, the airflow is blown out from the air outlet slot plate to blow the grinding part of the grinding sand shaft, thereby blowing the dust polished by the grinding sand shaft into the work box, preventing the uncertainty of the direction and speed of dust generation, resulting in some dust not being able to be sucked away in time, thereby flying in the air, polluting the working environment, and causing harm to the health of the operator.

[0021] 2. The cylindrical building material grinding device described in the present invention passes the pipe through the two axis boxes to align one end of the pipe with the limit plate, and then controls the hydraulic cylinder to drive the shaft rod to extend and retract. The shaft rod drives the two conical shaft blocks to move in the two axis boxes while extending and retracting. When the conical shaft block moves in the axis box, the conical shaft block squeezes and pushes multiple pipe clamping blocks in the axis box to move outward, thereby allowing the multiple conical shaft blocks to drive the multiple pipe clamping blocks to pull the multiple return springs to slide outward in the limit slide plate. When the multiple pipe clamping blocks in the two axis boxes contact the inner wall of the pipe, the multiple pipe clamping blocks in the two axis boxes support the two ends of the inner wall of the pipe, thereby realizing the retention of the pipe. The pipe is retained by moving the multiple pipe clamping blocks, so that the device can be suitable for fixing and installing pipes of different diameters, thereby fixing pipes of different diameters.

[0022] 3. The cylindrical building material grinding device described in the present invention drives the screw shaft to rotate by controlling the torque regulating motor in the shift box. When the screw shaft rotates, the screw shaft drives the torque box to slide on the top of the support plate through the shift plate through the thread transmission screw shaft, so that the torque box pulls the pipe to move on the top of the support plate, thereby realizing the alignment of the welding point of the pipe and the grinding assembly, which plays a role in adjusting the alignment and grinding position.

[0023] 4. The cylindrical building material grinding device described in the present invention, when the hydraulic cylinder drives the grinding sand shaft to move downward through the connecting frame, the hydraulic cylinder also drives the rack rod to move downward through the connecting frame, and when the rack rod moves downward, it can drive two L-shaped racks to move upward through the tooth meshing transmission, so that the L-shaped rack drives two support pipe rack rods to move upward, so that the two support pipe rack rods support the circumference of the pipe, to prevent the pipe from being displaced due to the grinding strain pressure of the grinding sand shaft on the pipe during rotation, thereby affecting the grinding effect, and playing the role of supporting the pipe.

[0024] 5. The cylindrical building material grinding device described in the present invention drives the grinding shaft to move downward for grinding by the hydraulic cylinder, and the hydraulic cylinder also drives the pressure rod to move downward, thereby pushing the slag blocking plate to squeeze the push plate spring to rotate in the slag box, so that the slag blocking plate is opened in the slag box to provide an entrance for the entry of dust; when the operation is completed, the hydraulic cylinder drives the grinding shaft to reset, and the push plate spring will lose the squeezing of the pressure rod. Under the elastic push of the push plate spring, the slag blocking plate will rotate and close in the slag box, thereby closing the slag box and preventing the dust entering the slag box from drifting out of the slag box, thereby blocking the outflow of dust.

DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 9 As shown, a cylindrical building material grinding device described in an embodiment of the present invention includes a support plate 1, a work box 3 is fixedly installed on the top of the support plate 1, a grinding assembly is arranged inside the work box 3, and the grinding assembly is used to grind the welding surface of the pipe, a dust collecting assembly is arranged inside the work box 3, and the dust collecting assembly is arranged on one side of the grinding assembly, and the dust collecting assembly includes an air outlet slot plate 501, and the dust collecting assembly is used to collect dust under the grinding of the grinding assembly through the air outlet slot plate 501, a moving component assembly is arranged on one side of the top of the support plate 1, and the moving component assembly is used to drive the pipe and the grinding component to calibrate the position, and a fixing component is arranged outside the moving component, and the fixing component is used to fix the pipe in place, and a supporting material assembly is arranged inside the work box 3, and the supporting material assembly is used to support the pipe when the grinding component is grinding the pipe;

[0038] Due to the uncertainty of the direction and speed of dust generation, some dust cannot be removed in time, thus polluting the working environment and causing harm to the health of operators;

[0039] By fixing the pipe on the fixing material component, and then controlling the moving component to drive the welding part of the pipe to calibrate the position with the grinding component in the working box 3, when the calibration of the two is completed, start the grinding component to grind the welding surface of the pipe. While the grinding component is grinding, the dust collecting component collects the dust generated by the grinding component through the air outlet slot plate 501, so that the dust generated by the grinding component is collected in one place to prevent the uncertainty of the direction and speed of the dust generation, resulting in some dust not being sucked away in time, thereby polluting the working environment and causing harm to the health of the operator. At the same time, when the grinding component is grinding the pipe, the supporting material component supports the pipe to prevent the pipe from being displaced due to the strain pressure generated by grinding during grinding, thereby affecting the grinding effect. It should be noted here that the cylindrical building material polished in this scheme is a metal pipe.

[0040] like Figures 3 to 5 As shown, the solid material assembly includes an axis box 202, and there are two axis boxes 202. The internal structure of the two axis boxes 202 is the same. The two axis boxes 202 are fixedly connected by a vertical rod. The inner walls of the two axis boxes 202 are fixedly installed with a group of limiting slide plates 2010. The inner walls of the two axis boxes 202 are slidably connected with a group of clamping tube blocks 206. The outer walls of the two groups of clamping tube blocks 206 are slidably connected with the two groups of limiting slide plates 2010 and the inner walls of the axis boxes 202 respectively. The outer walls of the two groups of clamping tube blocks 206 are fixedly installed with a group of push blocks 208. The push blocks 208 are slidably connected with the inner walls of the axis boxes 202. One side of the two groups of clamping tube blocks 206 is connected to the inner wall of the two axis boxes 202. A group of return springs 209 are arranged between the walls, one side of one shaft box 202 is fixedly connected to the limit plate 2, one side of the limit plate 2 is fixedly installed with a slot box 205, the inner wall of the slot box 205 is fixedly installed with a hydraulic cylinder 204, the output end of the hydraulic cylinder 204 is fixedly installed with a shaft rod 203, the outer wall of the shaft rod 203 is slidably connected with the limit plate 2 and the inner walls of the two shaft boxes 202, the outer wall of the shaft rod 203 is fixedly installed with two conical shaft blocks 207, the outer walls of the two conical shaft blocks 207 are respectively slidably connected with the outer walls of the two groups of push blocks 208, the outer walls of one end of the two groups of push blocks 208 are both inclined sliding surfaces, and the outer walls of one side of the two groups of clamping pipe blocks 206 are both cambered surfaces;

[0041] When the pipe is fixedly installed, the pipe is passed through the two shaft boxes 202, one end of the pipe is flush with the limit plate 2, and then the hydraulic cylinder 204 is controlled to drive the shaft rod 203 to extend and retract. The shaft rod 203 drives the two cone shaft blocks 207 to move in the two shaft boxes 202 while extending and retracting. When the cone shaft block 207 moves in the shaft box 202, the cone shaft block 207 squeezes and pushes the multiple pipe clamping blocks 206 in the shaft box 202 to move outward, so that the multiple cone shaft blocks 207 drive the multiple pipe clamping blocks 2 06 pulls multiple return springs 209 to slide outward in the limiting slide plate 2010. When the multiple pipe clamping blocks 206 in the two shaft boxes 202 contact the inner wall of the pipe, the hydraulic cylinder 204 stops working. At this time, the multiple pipe clamping blocks 206 in the two shaft boxes 202 support the two ends of the inner wall of the pipe, thereby fixing the pipe. By moving the multiple pipe clamping blocks 206 to fix the pipe, the device can be suitable for fixing and installing pipes of different diameters, thereby fixing pipes of different diameters.

[0042] like Figures 4 to 5 As shown, the top of the support plate 1 is slidably connected to a rectangular box 804, the inner wall of the rectangular box 804 is slidably connected to a support seat, a rotating tube motor 201 is fixedly installed on the top of the support seat, and the output end of the rotating tube motor 201 is fixedly connected to one side of the slot box 205;

[0043] When the pipe is fixed, the position of the welding part of the pipe that needs to be polished is aligned with the polishing assembly by controlling the moving component. When the alignment of the two is completed, the pipe rotating motor 201 is controlled to drive the slot box 205 to rotate, so that the pipe rotating motor 201 drives the pipe to rotate, which can speed up the polishing speed of the pipe and also enable the polishing assembly to polish the welding surface of the pipe more comprehensively.

[0044] like Figure 1 to Figure 2 As shown, the shifting component includes a torque-adjusting motor 801, a shifting box 8 is fixedly installed at the bottom of the support plate 1, the torque-adjusting motor 801 is fixedly installed on the inner wall of the shifting box 8, a screw shaft 802 is fixedly installed at the output end of the torque-adjusting motor 801, a shifting plate 803 is threadedly connected to the outer wall of the screw shaft 802, the top of the shifting plate 803 is fixedly connected to the bottom of the torque box 804, and the outer wall of the shifting plate 803 is slidably connected to the inner wall of the support plate 1;

[0045] When the pipe is fixed, the torque regulating motor 801 in the shift box 8 is controlled to drive the screw shaft 802 to rotate. When the screw shaft 802 rotates, the screw shaft 802 drives the torque box 804 to slide on the top of the support plate 1 through the shift plate 803 through the thread transmission, so that the torque box 804 pulls the pipe to move on the top of the support plate 1, thereby realizing the alignment of the welding point of the pipe and the grinding component, which plays the role of adjusting the alignment.

[0046] like Figures 6 to 8As shown, the grinding assembly includes a connecting frame 302, the inner wall of the connecting frame 302 is rotatably connected to a grinding sand shaft 7, a retaining frame 702 is fixedly installed on one side of the connecting frame 302, a bidirectional motor 701 is fixedly installed on one side of the retaining frame 702, one end of the output end of the bidirectional motor 701 is fixedly connected to one side of the grinding sand shaft 7, and the grinding sand shaft 7 is placed on the upper side of the pipe;

[0047] When the pipe position calibration is completed, the pipe rotating motor 201 is controlled to drive the pipe to rotate, and at the same time, the bidirectional motor 701 drives the grinding shaft 7 to rotate. When the grinding shaft 7 rotates, the grinding shaft 7 grinds the welding part of the pipe to play a grinding role. It should be noted here that the direction in which the pipe rotating motor 201 drives the pipe to rotate is opposite to the direction in which the grinding shaft 7 rotates.

[0048] like Figure 6 to Figure 7 As shown, a hydraulic cylinder 301 is fixedly installed on the top of the work box 3, the output end of the hydraulic cylinder 301 is fixedly connected to the top of the connecting frame 302, and the outer wall of the connecting frame 302 is slidably connected to the inner wall of the work box 3;

[0049] Since the position of the pipe welding point is higher than the height of the pipe, when the pipe needs to be polished, the two-way motor 701 drives the polishing shaft 7 to rotate, and the hydraulic cylinder 301 drives the polishing shaft 7 to move downward through the connecting frame 302. When the polishing shaft 7 contacts the pipe welding point, the pipe and the polishing shaft 7 rotate in opposite directions, so that the polishing shaft 7 polishes the pipe welding point. At the same time, the hydraulic cylinder 301 drives the polishing shaft 7 to move downward continuously, so that the polishing shaft 7 can continue to polish the pipe welding point, thereby completing the polishing operation of the pipe welding position, which plays a role in controlling the feed of the polishing shaft 7.

[0050] like Figures 6 to 8 As shown, the dust collecting assembly further includes a shaft disc 502, which is fixedly mounted on the other side of the retaining frame 702, and an axial flow fan 503 is fixedly mounted on the other output end of the bidirectional motor 701, and the axial flow fan 503 is placed inside the shaft disc 502, and an air outlet slot plate 501 is fixedly mounted on one side of the connecting frame 302, and the air outlet slot plate 501 is placed on the upper side of the sanding shaft 7, and an air flow pipe 5 is fixedly connected between the air outlet slot plate 501 and the shaft disc 502;

[0051] When the bidirectional motor 701 drives the grinding sanding shaft 7 to rotate to grind the pipe, the bidirectional motor 701 also drives the axial flow fan 503 to rotate. When the axial flow fan 503 rotates, the axial flow fan 503 will blow out airflow, and then through the continuous rotation of the axial flow fan 503, the airflow will enter the air outlet slot plate 501 along the airflow pipe 5, and finally blow out from the bottom of the air outlet slot plate 501, so that when the grinding sanding shaft 7 grinds the pipe, the airflow is blown out from the air outlet slot plate 501 to the grinding sanding shaft 7. Blowing is performed at the grinding place, so that the dust produced by the grinding sand shaft 7 is blown into the work box 3 to prevent the uncertainty of the direction and speed of dust generation, which may cause some dust to fail to be sucked away in time and fly into the air, thereby polluting the working environment and causing harm to the health of operators. It plays a role in preventing dust from floating out. It should be noted here that the angle of the air outlet at the bottom of the air outlet groove plate 501 is consistent with the grinding angle of the grinding sand shaft 7, and the inner wall of the shaft disk 502 is provided with multiple air flow inlets.

[0052] like Figure 6 to Figure 7 As shown, the supporting material assembly includes a pipe support rod 6, and there are two pipe support rods 6. The two pipe support rods 6 are slidably connected to the inner wall of the support plate 1. A strip frame plate 604 is fixedly installed on the top of the support plate 1. A tooth column 602 is rotatably connected inside the strip frame plate 604. An L-shaped tooth rod 601 is fixedly installed on the bottom of the two pipe support rods 6. A rack rod 603 is fixedly installed on the outer wall of the connecting frame 302. The teeth on the rack rod 603 and the two L-shaped tooth rods 601 are respectively meshed with the teeth on the tooth column 602. The top ends of the two pipe support rods 6 can fit with the outer wall of the pipe.

[0053] When the hydraulic cylinder 301 drives the grinding shaft 7 to move downward through the connecting frame 302, the hydraulic cylinder 301 also drives the rack rod 603 to move downward through the connecting frame 302. When the rack rod 603 moves downward, the two L-shaped rack rods 601 can be driven to move upward through the tooth meshing transmission, so that the L-shaped rack rods 601 drive the two pipe support rack rods 6 to move upward, so that the two pipe support rack rods 6 support the pipe all around, to prevent the pipe from being displaced due to the grinding strain pressure of the grinding shaft 7 when the pipe is rotating, thereby affecting the grinding effect, and playing the role of supporting the pipe.

[0054] like Figures 8 to 9 As shown, a slag box 4 is fixedly installed on the inner wall of the working box 3, a slag blocking plate 403 is rotatably connected to the inner wall of the slag box 4, a push plate spring 404 is arranged between the bottom of the slag blocking plate 403 and the inner wall of the slag box 4, and pressure rods 405 are symmetrically fixedly installed on the bottom of the connecting frame 302, and the bottom ends of the two pressure rods 405 are placed just above the slag blocking plate 403;

[0055] When the hydraulic cylinder 301 drives the grinding shaft 7 to move downward for grinding through the connecting frame 302, the connecting frame 302 also drives the pressure rod 405 at its bottom to move downward. When the pressure rod 405 moves downward, it pushes the slag blocking plate 403 to squeeze the push plate spring 404 to rotate in the slag box 4, thereby opening the slag blocking plate 403 in the slag box 4 to provide an entrance for the entry of dust. When the operation is completed, the hydraulic cylinder 301 drives the grinding shaft 7 to reset, and the push plate spring 404 will lose the squeezing of the pressure rod 405. Under the elastic push of the push plate spring 404, the slag blocking plate 403 will rotate and close in the slag box 4, thereby closing the slag box 4 to prevent the dust entering the slag box 4 from drifting out of the slag box 4, thereby blocking the outflow of dust.

[0056] like Figures 8 to 9 As shown, a suction fan 401 and a slag blocking plate 402 are fixedly installed inside the slag box 4, and the suction fan 401 is placed on one side of the slag blocking plate 402;

[0057] When the air outlet slot plate 501 blows the dust, the exhaust fan 401 in the slag box 4 performs an exhaust operation, so that when the dust is blown into the working box 3 by the air outlet slot plate 501, the exhaust fan 401 draws the dust, so that the dust passes through the slag blocking plate 403 and enters the slag box 4, playing a role in cooperating with the dust collection operation of the air outlet slot plate 501. The slag blocking plate 402 is provided to block the dust and prevent the dust from contacting the slag box 4 and affecting the exhaust operation of the slag box 4.

[0058] Working principle: by fixing the pipe on the fixing material component, and then controlling the moving component to drive the welding part of the pipe to calibrate the position with the grinding component in the working box 3, when the calibration of the two is completed, start the grinding component to grind the welding surface of the pipe, and while the grinding component is grinding, the dust collecting component collects the dust generated by the grinding component through the air outlet slot plate 501, so that the dust generated by the grinding component is collected in one place to prevent the uncertainty of the direction and speed of the dust generation, resulting in some dust not being sucked out in time, thereby polluting the working environment and causing harm to the health of the operator. At the same time, when the grinding component is grinding the pipe, the supporting material component supports the pipe to prevent the pipe from being displaced due to the strain pressure generated by grinding during grinding, thereby affecting the grinding effect;

[0059] When the pipe is fixedly installed, the pipe is passed through the two shaft boxes 202, one end of the pipe is flush with the limit plate 2, and then the hydraulic cylinder 204 is controlled to drive the shaft rod 203 to extend and retract. The shaft rod 203 drives the two cone shaft blocks 207 to move in the two shaft boxes 202 while extending and retracting. When the cone shaft block 207 moves in the shaft box 202, the cone shaft block 207 squeezes and pushes the multiple pipe clamping blocks 206 in the shaft box 202 to move outward, so that the multiple cone shaft blocks 207 drive the multiple pipe clamping blocks 2 06 pulls the multiple return springs 209 to slide outward in the limiting slide plate 2010. When the multiple pipe clamping blocks 206 in the two shaft boxes 202 contact the inner wall of the pipe, the hydraulic cylinder 204 stops working. At this time, the multiple pipe clamping blocks 206 in the two shaft boxes 202 support the inner walls of the pipe at both ends, thereby achieving the fixation of the pipe. The multiple pipe clamping blocks 206 move to fix the pipe, so that the device can be used for fixing and installing pipes of different diameters, and plays the role of fixing pipes of different diameters.

[0060] When the pipe is fixed, the position of the welding part of the pipe to be polished is aligned with the polishing assembly by controlling the moving component. When the alignment is completed, the pipe rotating motor 201 is controlled to drive the slot box 205 to rotate, so that the pipe rotating motor 201 drives the pipe to rotate, which can speed up the polishing speed of the pipe and also enable the polishing assembly to polish the welding surface of the pipe more comprehensively.

[0061] When the pipe is fixed, the torque regulating motor 801 in the shift box 8 is controlled to drive the screw shaft 802 to rotate. When the screw shaft 802 rotates, the screw shaft 802 drives the torque box 804 to slide on the top of the support plate 1 through the shift plate 803 through the thread transmission, so that the torque box 804 pulls the pipe to move on the top of the support plate 1, thereby realizing the alignment of the welding part of the pipe and the grinding component, which plays the role of adjusting the alignment.

[0062] When the position calibration of the pipe is completed, the pipe rotating motor 201 is controlled to drive the pipe to rotate, and at the same time, the bidirectional motor 701 drives the grinding shaft 7 to rotate. When the grinding shaft 7 rotates, the grinding shaft 7 grinds the welding part of the pipe to play a grinding role;

[0063] When the pipe needs to be polished, the two-way motor 701 drives the polishing shaft 7 to rotate, and the hydraulic cylinder 301 drives the polishing shaft 7 to move downward through the connecting frame 302. When the polishing shaft 7 contacts the pipe welding part, the pipe and the polishing shaft 7 rotate in opposite directions, so that the polishing shaft 7 polishes the pipe welding part. At the same time, the hydraulic cylinder 301 drives the polishing shaft 7 to move downward continuously, so that the polishing shaft 7 can continuously polish the pipe welding part, thereby completing the polishing operation of the pipe welding position, which plays a role in controlling the feeding of the polishing shaft 7.

[0064] When the bidirectional motor 701 drives the grinding shaft 7 to rotate to grind the pipe, the bidirectional motor 701 also drives the axial flow fan 503 to rotate. When the axial flow fan 503 rotates, the axial flow fan 503 will blow out airflow, and then through the continuous rotation of the axial flow fan 503, the airflow will enter the air outlet slot plate 501 along the airflow pipe 5, and finally blow out from the bottom of the air outlet slot plate 501, so that when the grinding shaft 7 grinds the pipe, the airflow is blown out from the air outlet slot plate 501 to blow the grinding part of the grinding shaft 7, so that the dust polished by the grinding shaft 7 is blown into the working box 3, so as to prevent the uncertainty of the direction and speed of the dust from being unable to be sucked out in time, so that it flies in the air, thereby polluting the working environment and causing harm to the health of the operator, thereby preventing the dust from floating out;

[0065] When the hydraulic cylinder 301 drives the grinding shaft 7 to move downward through the connecting frame 302, the hydraulic cylinder 301 also drives the rack rod 603 to move downward through the connecting frame 302. When the rack rod 603 moves downward, the two L-shaped rack rods 601 can be driven to move upward through the tooth meshing transmission, so that the L-shaped rack rods 601 drive the two pipe support rack rods 6 to move upward, so that the two pipe support rack rods 6 support the pipe around the body, to prevent the pipe from being displaced due to the grinding strain pressure of the grinding shaft 7 when the pipe is rotating, thereby affecting the grinding effect, and playing the role of supporting the pipe;

[0066] When the hydraulic cylinder 301 drives the grinding shaft 7 to move downward for grinding through the connecting frame 302, the connecting frame 302 also drives the pressure rod 405 at its bottom to move downward. When the pressure rod 405 moves downward, it pushes the slag blocking plate 403 to squeeze the push plate spring 404 to rotate in the slag box 4, so that the slag blocking plate 403 is opened in the slag box 4 to provide an entrance for the entry of dust. When the operation is completed, the hydraulic cylinder 301 drives the grinding shaft 7 to reset, and the push plate spring 404 loses the squeezing of the pressure rod 405. Under the elastic push of the push plate spring 404, the slag blocking plate 403 rotates and closes in the slag box 4, thereby closing the slag box 4 to prevent the dust entering the slag box 4 from drifting out of the slag box 4, thereby blocking the outflow of dust.

[0067] When the air outlet slot plate 501 blows the dust, the exhaust fan 401 in the slag box 4 performs an exhaust operation, so that when the dust is blown into the working box 3 by the air outlet slot plate 501, the exhaust fan 401 draws the dust, so that the dust passes through the slag blocking plate 403 and enters the slag box 4, playing a role in cooperating with the dust collection operation of the air outlet slot plate 501. The slag blocking plate 402 is provided to block the dust and prevent the dust from contacting the slag box 4 and affecting the exhaust operation of the slag box 4.
