Description

Technical Field

[0001] The present invention relates to the technical field of flange processing, and particularly to a multi-axis drilling device for processing hot blast stove flanges. Background Art

[0002] As a core device in fields such as metallurgy and chemical industry, the processing quality of the flange of a hot blast stove directly affects the airtightness, pressure resistance performance and service life of the furnace body. A typical hot blast stove flange is usually of a ring structure, and a plurality of high-precision bolt holes need to be evenly distributed along the circumferential direction, and chamfering treatment needs to be carried out at the hole edge to avoid stress concentration.

[0003] Traditional processing technologies mostly adopt a step-by-step operation mode: first, manual scribing and positioning are carried out, and holes are drilled one by one using a single-axis drill press, and then it is transferred to a chamfering device for secondary processing. However, with the development of industrial equipment towards large-scale and high-parameterization, the traditional technology has exposed significant defects:

[0004] After retrieval, a Chinese patent with the publication number CN215509040U discloses a flange drilling device, which realizes the technical effects of supporting and rotating adjustment of the flange, and realizes the technical effect of adjusting the drilling position by means of screw drive. However, there are still the following several problems:

[0005] 1. Since the surface of the flange is usually smooth and hard, the drill bit is prone to slip during direct drilling, which easily leads to the deviation of the hole position. Therefore, how to solve the problem of drill bit slipping is an urgent problem to be solved now;

[0006] 2. Single-axis drilling requires frequent replacement of the workpiece position or repeated clamping. Especially for multi-hole flanges, the processing time is extremely long, and there are many manual intervention links, which seriously restricts the processing efficiency of the flange. Therefore, how to solve the problem of low single-axis processing efficiency is an urgent problem to be solved now;

[0007] 3. When processing the flange, the pre-tapping, drilling and chamfering processes are scattered on different devices, and the intermediate links rely on manual handling, which not only increases the management cost, but also easily causes burr residues at the hole mouth due to improper process connection. Therefore, how to ensure the continuity of production is an urgent problem to be solved now;

[0008] 4. When completing the chamfering operation on one side of the flange, it is necessary to manually turn over the flange to chamfer the hole edge on the other side of the hole. It is difficult to ensure that the holes of the flange are consistent with those before the first flip during manual flipping, and it is difficult to ensure the angles of chamfers on both sides, resulting in chamfering deviation. Therefore, how to solve the problem of turning over the flange and ensuring the accuracy is also an urgent problem to be solved now. Summary of the Invention

[0009] Technical Problems to be Solved

[0010] In view of the deficiencies of the prior art, the present invention provides a multi-axis drilling device for processing hot blast stove flange plates, mainly to solve the problems that since the surface of the flange plate is usually smooth and hard, the drill bit is prone to slip during direct drilling, resulting in the deviation of the hole position, and the need to frequently change the workpiece position or repeat clamping during single-axis drilling. Especially for multi-hole flange plates, the processing time is extremely long, and there are many manual intervention links, which seriously restricts the processing efficiency of the flange plate. When processing the flange plate, the processes of pre-knocking points, drilling, and chamfering are scattered on different devices, and the intermediate links rely on manual handling, which not only increases the management cost but also easily causes burr residues at the hole mouth due to improper process connection. When chamfering the edge of the hole on the other side of the flange plate after chamfering one side of the flange plate, it is necessary to manually turn over the flange plate. It is difficult to ensure that the holes of the flange plate are consistent with those before the first turn during manual turning, and it is difficult to ensure the chamfering angles on both sides, resulting in chamfering deviation.

[0023] Beneficial effects

[0024] Compared with the prior art, the present invention provides a multi-axis drilling device for processing a hot blast stove flange, having the following beneficial effects:

[0025] 1. Before drilling the flange, the present invention first knocks out a groove on its surface through the provided knocking point assembly, avoiding the drill bit from sliding easily during direct drilling due to the usually smooth and hard metal surface, resulting in hole position deviation. The groove provides a physical guiding point for the drill bit to ensure accurate initial positioning.

[0026] 2. Through the coordinated use of the knocking point assembly, drilling assembly and chamfering assembly, the present invention can perform efficient and continuous processing, reducing process switching. The three steps of pre-knocking points, drilling, and chamfering are sequentially completed on the same device, without manual handling or equipment replacement, significantly shortening the processing cycle and saving the time for repeated adjustment of workpiece clamping and positioning. Especially for the processing of multi-hole flanges, the processing efficiency is significantly improved.

[0027] 3. Through the coordinated use of the provided positioning assembly and flipping assembly, the present invention realizes double-sided chamfering, improves processing integrity, can automatically complete workpiece flipping, avoids the inefficiency and errors of manual operation, and can ensure the consistency of the angles, depths, and shapes of the chamfers on both sides, avoiding deviations caused by manual flipping.

[0028] 4. Through the coordinated use of the adjusting assembly and the tensioning assembly, while being able to adjust the direct distance between the two sets of sliders two to adjust the knocking point distance, drilling distance, and chamfering distance, it can ensure the tension of the synchronous belt, dynamically adapt to changes in working conditions, maintain transmission stability, and avoid slipping, tooth skipping, or reduction in transmission efficiency caused by slack.

[0029] 5. Through the provided transverse movement assembly, the present invention efficiently ensures multi-station collaborative operation. The flange is sequentially moved to the knocking point, drilling, and chamfering stations through the transverse movement assembly, without manual handling or repeated clamping, realizing continuous operation of "processing - moving - processing", and significantly shortening the single-piece processing time.

[0030] 6. By setting two synchronous operations during pre-knocking points, drilling, and chamfering operations, the present invention synchronously processes symmetric holes, shortens the processing cycle of the flange, and effectively increases the processing efficiency of the flange.

After the flange to be processed is clamped, the knocking component 4 can be used to knock out grooves on the surface of the flange. During the knocking process, the first hydraulic cylinder 401 is started to contract, thereby driving the connecting frame 8 thereon to move downward. During the downward movement of the connecting frame 8, the guide tube 4031 moves downward synchronously. After the bottom end of the guide tube 4031 contacts the flange, the telescopic cylinder 4032 is started to contract rapidly, and then the connecting rod 4034 is driven to move rapidly downward along the guide tube 4031 through the square telescopic rod 4033, so as to knock the flange through the conical head 4035 to make pits appear on the surface of the flange, preparing for the subsequent drilling operation. Then, the telescopic cylinder 4032 is started to extend. After the first knocking is completed, the first hydraulic cylinder 401 is started to extend slightly to make the guide tube 4031 disengage from the flange. Then, the stepping motor 12033 is started to rotate according to the set program, so that the flange rotates. After each rotation is completed, the electromagnetic pin lock 12035 thereon is reinserted into the corresponding side hole 12034 to fix the rotating tray 12032. Then, the knocking operation is repeated. After the knocking is completed, the fixing component 12 is sent to the lower part of the drilling component 5 through the transverse movement component 11. When transverse movement is required, the linear motor module one 1103 is started to drive the sliding seat 1201 to move horizontally along the first sliding port 2 until the flange thereon is directly below the drilling component 5. After the movement is completed, the drilling component 5 can be used to drill the flange. The chamfering component 6 includes a third hydraulic cylinder 601 fixedly connected to the left side of the frame body 3 by bolts, and a third box body 602 is fixedly connected to the top end of the third hydraulic cylinder 601 by bolts. The knocking component 4, the drilling component 5 and the chamfering component 6 also include connecting pipes 7 respectively fixedly connected to the bottoms of the first box body 402, the second box body 502 and the third box body 602 by bolts. The bottom ends of the plurality of connecting pipes 7 are all fixedly connected with connecting frames 8 by bolts. Two sets of symmetrically arranged upper and lower sliding ports 901 are formed on the connecting frames 8. A second slider 908 is slidably connected in each of the plurality of sliding ports 901. The two second sliders 908 in the same upper and lower group are connected by a fixing rod 907. An adjusting component 9 capable of synchronously adjusting the positions of the two sets of second sliders 908 is provided on the outer walls of the tops of the plurality of connecting frames 8. A knocking component 403 is arranged in the connecting frame 8 of the knocking component 4. The knocking component 403 includes a guide tube 4031 welded through two second sliders 908 at the bottom of the connecting frame 8 below the knocking component 4. A telescopic cylinder 4032 is fixedly connected to the bottom inner wall of this connecting frame 8 by bolts.The output end of the telescopic cylinder 4032 is fixedly connected with two symmetrical square telescopic rods 4033 through bolts. On one side of the lower surfaces of the two square telescopic rods 4033, connecting rods 4034 that slide in the guide tube 4031 are fixedly connected through bolts. The bottom end of the connecting rod 4034 is fixedly connected with a conical head 4035 for dotting. On the lower surfaces of the second sliders 908 at the bottom of the drilling assembly 5 and the chamfering assembly 6, chucks 5036 are rotatably connected. The top ends of the chucks 5036 pass through the second sliders 908 connected to them and are fixed to the second synchronous pulleys 5034. And a drilling bit 504 and a chamfering bit 603 are respectively arranged in the two groups of chucks 5036. Between the two groups of chucks 5036 below the drilling assembly 5 and the chamfering assembly 6 and the connecting frame 8, driving assemblies 503 for rotating the chucks 5036 are provided. When drilling operations are required, the driving assembly 503 is started to make the drilling bit 504 rotate at a high speed and wait for drilling. When starting the driving assembly 503, first start the first driving motor 5031 so that its output shaft drives the rotating shaft 5032 to rotate at a high speed. While the rotating shaft 5032 is rotating, the first synchronous pulley 5033 on it rotates. While the first synchronous pulley 5033 is rotating, the second synchronous pulley 5034 is driven to rotate through the synchronous belt 5035, so that the chuck 5036 connected to it rotates at a high speed. While the chuck 5036 is rotating at a high speed, the drilling bit 504 on it will rotate at a high speed. Then start the second hydraulic cylinder 501 to contract, driving the drilling bit 504 to move downward. When it contacts the flange, drilling operations can be carried out on it. After a drilling operation is completed, start the second hydraulic cylinder 501 to extend, driving the drilling bit 504 to move upward until it is completely separated from the flange. Then repeat the rotation step of the rotating assembly 1203 in the above steps, and then drill again. In this way, the flange is drilled multiple times. During the drilling operation, cutting fluid is sprayed onto the drilling area of the flange through the cutting fluid spray pipe 1205. After the drilling operation is completed, the fixing assembly 12 is sent to directly below the chamfering assembly 6 through the transverse movement assembly 11. When chamfering operations are required, start the driving assembly 503 in the chamfering assembly 6 as described above to drive the chamfering bit 603 to rotate at a high speed. Then start the third hydraulic cylinder 601 to contract, so that the chamfering bit 603 moves downward until it contacts the edge of the hole drilled in the flange, and chamfering operations can be carried out on it. After one chamfering is completed, start the third hydraulic cylinder 601 to extend, so that the chamfering bit 603 moves upward until the chamfering bit 603 is above the flange. Then repeat the rotation step of the rotating assembly 1203 above, and then carry out chamfering operations again. In this way, multiple holes on one side of the flange are chamfered. During the chamfering operation, cutting fluid is sprayed onto the chamfering area of the flange through the cutting fluid spray pipe 1205.,

[0051] To solve the problem of adjusting the distance between the processing shafts, the adjusting assembly 9 includes a first slider 902 fixedly connected to the upper surfaces of two second sliders 908 located at the top of the connecting frame 8 by bolts. On the outer wall of the top of the connecting frame 8 and on both sides of the two second sliding openings 901, a first fixing block 903 is fixedly connected by bolts. On the outer wall of the top of the connecting frame 8 and between the two second sliding openings 901, two symmetric second fixing blocks 904 are fixedly connected by bolts. A first bidirectional lead screw 905 is rotatably connected between the two second fixing blocks 904 through a bearing. The first bidirectional lead screw 905 passes through the two first sliders 902 and is threadedly connected thereto and passes through the two second fixing blocks 904 and is rotatably connected thereto. The threaded portion of the first bidirectional lead screw 905 is located between the first fixing block 903 and the second fixing block 904. One end of the first bidirectional lead screw 905 passes through the corresponding first fixing block 903, and a pin for fixing the first bidirectional lead screw 905 is provided on one side of the first fixing block 903. A grip 906 is provided on the circumferential outer wall of the first bidirectional lead screw 905 at the middle position. When it is necessary to adjust the distance between the two groups of second sliders 908, the first bidirectional lead screw 905 is rotated to drive the two groups of second sliders 908 to move in the direction of approaching or separating from each other through the first slider 902. After the adjustment is completed, the first bidirectional lead screw 905 is fixed by the electromagnetic pin lock 12035 at one end of the first bidirectional lead screw 905. After the fixing is completed, the second threaded rod 1303 is rotated to drive the U-shaped frame 1302 to slide, thereby adjusting the tightness of the synchronous belt 5035.

[0052] To solve the problem that the workpiece position needs to be frequently changed or reinstalled during single-axis drilling. Especially for multi-hole flanges, the processing time is extremely long, and there are many manual intervention links, which seriously restricts the processing efficiency of flanges. The flipping assembly 14 includes a bottom plate 1401 fixedly connected to the upper surface of the workbench 1 by bolts. The upper surface of the bottom plate 1401 is fixedly connected with a linear motor module two 1402 by bolts. The surface of the mover of the linear motor module two 1402 is fixedly connected with an L-shaped table 1403 by bolts. One side of the L-shaped table 1403 is fixedly connected with a rotary cylinder 1404 by bolts. The rotary end of the rotary cylinder 1404 is fixedly connected with a cross plate 1405 by bolts. At both ends of one side of the cross plate 1405, finger cylinders 1406 for clamping the flange are fixedly connected by bolts. The middle position between the two clamping jaws of the finger cylinder 1406 is higher than the top of the cylindrical clamping block 12045. After chamfering is completed at the edge of the hole on one side of the flange, first start the drive motor two 12048 to reverse, thereby driving the two-way lead screw two 12047 to flip, and then drive the cylindrical clamping block 12045 to move away from each other through the two U-shaped plates 12044, so as to loosen the flange. Then start the linear motor module two 1402 to drive the L-shaped table 1403 to move towards the flange through the mover component on it until the bottom clamping jaw of the finger cylinder 1406 on it is under the flange. Start the finger cylinder 1406 to clamp the flange. During the clamping process, the flange will first tilt. When the upper clamping jaw contacts the flange, the two clamping jaws will move closer to clamp the flange. At this time, the lower surface of the flange is higher than the cylindrical clamping block 12045. Then move the flange out through the reverse movement of the linear motor module two 1402. Then start the rotary cylinder 1404 to rotate the flange 180 degrees. After the rotation is completed, send the flange back to the cross-shaped plate frame 12041 again, and then return the flipping assembly 14 to its original position. The positioning assembly 1206 includes two symmetric T-shaped seats 12061 fixedly connected to the upper surface of the slide base 1201 by bolts. One end of the T-shaped seat 12061 is slidably connected through a slide frame 12062. Both ends of the slide frame 12062 are respectively fixedly connected with an end block 12063 and an end plate 12068 by bolts. The lower surface of the end block 12063 is fixedly connected with a micro cylinder 12064 by bolts. The output end of the micro cylinder 12064 is fixedly connected with a positioning head 12065 by bolts. An avoidance port 12066 is opened on the T-shaped seat 12061 and at a position below the slide frame 12062. An electric telescopic rod 12067 is fixedly connected in the avoidance port 12066 by bolts. The output end of the electric telescopic rod 12067 is fixed to one side of the end plate 12068. A threaded rod one 12069 for adjusting the distance between the end plate 12068 and it is threadedly connected through the end plate 12068. After the flange is re-placed on the cross-shaped plate frame 12041, the holes on the flange are positioned by the two positioning assemblies 1206.During the positioning process, start the electric telescopic rod 12067 to contract, and then drive the carriage 12062 to slide through the end plate 12068. Then drive the micro cylinder 12064 to move through the end block 12063. When the positioning head 12065 below the micro cylinder 12064 is above the flange hole, then start the micro cylinder 12064 to extend, driving the positioning head 12065 to move downward until it extends into the flange hole. The simultaneous operation of the two positioning components 1206 can ensure that the flange hole corresponds to the chamfering component 6. After positioning, start the second driving motor 12048 to rotate, and drive the cylindrical clamping blocks 12045 on it to move towards each other through the second bidirectional lead screw 12047 and the U-shaped plate 12044, thereby fixing the flange again. After fixing, return the positioning component 1206 to its initial state. Then repeat the above steps for chamfering the hole edge on the other side of the flange. After chamfering, loosen the flange, take out the processed flange through the flipping component 14, and then send the fixing component 12 to the starting point through the transverse movement component 11 to prepare for processing the next flange.,

[0053] In this application, an annular groove is axially arranged on the inner wall of the threaded barrel (threaded hole), and a nylon 66 damping ring with a Shore hardness of 85A is embedded in the groove. Through the continuous axial pressing force generated by its elastic deformation, it forms a helical angle interference fit with the surfaces of the first threaded rod 12069, the second threaded rod 1303, the first bidirectional lead screw 905, and the second bidirectional lead screw 12047. When the thread pair bears an axial vibration load, the nylon insert can produce an elastic compression of up to 0.3 mm, increasing the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing the loosening displacement caused by thread rebound.,

[0054] The present invention is used in the following steps:

[0055] S1: When in use, first place the flange to be processed on the upper surface of the cross-shaped plate frame 12041, and then start the second driving motor 12048 to drive the second bidirectional lead screw 12047 to rotate. During the rotation of the second bidirectional lead screw 12047, drive the two U-shaped plates 12044 to approach each other, so that the two groups of cylindrical clamping blocks 12045 on them squeeze the flange, squeeze it to the central position and tightly clamp it;

[0056] S2: After clamping the flange to be processed, the knocking component 4 can be used to knock out grooves on the surface of the flange. During the knocking process, the hydraulic cylinder 1 401 is activated to contract, driving the connecting frame 8 thereon to move downward. During the downward movement of the connecting frame 8, the guide pipe 4031 moves downward synchronously. After the bottom end of the guide pipe 4031 contacts the flange, the telescopic cylinder 4032 is activated to contract rapidly, and then the connecting rod 4034 is driven by the square telescopic rod 4033 to move rapidly downward along the guide pipe 4031. Thus, the flange is knocked by the conical head 4035 to create a pit on the surface of the flange, preparing for subsequent drilling operations. Subsequently, the telescopic cylinder 4032 is activated to extend. After the first knocking, the hydraulic cylinder 1 401 is activated to extend slightly to disengage the guide pipe 4031 from the flange. Then, the stepping motor 12033 is activated to rotate according to the set program, causing the flange to rotate. After each rotation is completed, the electromagnetic pin lock 12035 thereon is reinserted into the corresponding side hole 12034 to fix the rotating tray 12032. Subsequently, the knocking operation is repeated;

[0057] S3: After the knocking is completed, the fixing component 12 is sent below the drilling component 5 through the transverse movement component 11. When transverse movement is required, the linear motor module 1 1103 is activated to drive the sliding seat 1201 to move horizontally along the sliding slot 1 2 until the flange thereon is directly below the drilling component 5. After the movement is completed, the drilling component 5 can be used to perform drilling operations on the flange;

[0058] S4: When drilling operations are required, the driving component 503 is activated to make the drilling bit 504 rotate at high speed in preparation for drilling. When activating the driving component 503, the driving motor 1 5031 is first activated so that its output shaft drives the rotating shaft 5032 to rotate at high speed. While the rotating shaft 5032 is rotating, the synchronous pulley 1 5033 thereon rotates. While the synchronous pulley 1 5033 is rotating, the synchronous pulley 2 5034 is driven to rotate through the synchronous belt 5035, causing the chuck 5036 connected thereto to rotate at high speed. While the chuck 5036 is rotating at high speed, the drilling bit 504 thereon rotates at high speed. Subsequently, the hydraulic cylinder 2 501 is activated to contract, driving the drilling bit 504 to move downward. When it contacts the flange, drilling operations can be performed on it. After one drilling operation is completed, the hydraulic cylinder 2 501 is activated to extend, driving the drilling bit 504 to move upward until it is completely disengaged from the flange. Then, repeat the rotation steps of the rotating component 1203 in S2, and then perform drilling again. Repeat this process to drill the flange multiple times. While drilling, cutting fluid is sprayed onto the drilling area of the flange through the cutting fluid spray pipe 1205;

[0059] S5: After the punching operation is completed, the fixing component 12 is sent to directly below the chamfering component 6 through the transverse movement component 11. When the punching operation needs to be carried out, start the driving component 503 in the chamfering component 6 as in S4 to drive the chamfering drill bit 603 to rotate at a high speed. Then start the third hydraulic cylinder 601 to contract so that the chamfering drill bit 603 moves downward until it contacts the edge of the hole punched in the flange, and then the chamfering operation can be carried out on it. After one chamfering is completed, start the third hydraulic cylinder 601 to extend so that the chamfering drill bit 603 moves upward until the chamfering drill bit 603 is above the flange. Then repeat the rotation step of the rotation component 1203 in S2, and then carry out the chamfering operation again. In this way, chamfering is carried out on multiple holes on one side of the flange. While carrying out the chamfering operation, spray cutting fluid onto the chamfered part of the flange through the cutting fluid spray pipe 1205;

[0060] S6: After the chamfering operation is completed on the hole edges on one side of the flange, first start the second driving motor 12048 to reverse, which drives the second bidirectional lead screw 12047 to rotate, so that the cylindrical clamping blocks 12045 are driven by the two U-shaped plates 12044 to move away from each other, thereby loosening the flange. Then start the second linear motor module 1402, and its moving part drives the L-shaped table 1403 to move towards the flange until the bottom jaws of the finger cylinder 1406 on it are below the flange. Start the finger cylinder 1406 to clamp the flange. During the clamping process, the flange will first tilt. When the upper jaw contacts the flange, the two jaws will move closer to clamp the flange. At this time, the lower surface of the flange is higher than the cylindrical clamping block 12045. Then move the flange out through the reverse movement of the second linear motor module 1402. Then start the rotary cylinder 1404 to rotate the flange 180 degrees. After the rotation is completed, send the flange back to the cross-shaped plate frame 12041 again, and then return the flipping component 14 to its original position;

[0061] S7: After the flange is repositioned on the cross-shaped plate frame 12041, the holes on the flange are positioned by two positioning components 1206. During the positioning process, the electric telescopic rod 12067 is started to contract, thereby driving the carriage 12062 to slide through the end plate 12068, and then driving the micro cylinder 12064 to move through the end block 12063. When the positioning head 12065 under the micro cylinder 12064 is above the flange hole, then start the micro cylinder 12064 to extend, driving the positioning head 12065 to move downward until it extends into the flange hole. The simultaneous operation of the two positioning components 1206 can ensure that the flange hole corresponds to the chamfering component 6. After the positioning is completed, start the second driving motor 12048 to rotate, and drive the cylindrical clamping blocks 12045 thereon to move towards each other through the second bidirectional lead screw 12047 and the U-shaped plate 12044, thereby fixing the flange again. After the fixing is completed, return the positioning component 1206 to its initial state, and then repeat step S5 to chamfer the edge of the hole on the other side of the flange. After the chamfering is completed, loosen the flange, take out the processed flange through the flipping component 14, and then send the fixing component 12 to the starting point through the transverse movement component 11 to prepare for processing the next flange;

[0062] S8: When it is necessary to adjust the distance between the two sets of sliders two 908, rotate the first bidirectional lead screw 905, thereby driving the two sets of sliders two 908 to move towards each other or away from each other through the slider one 902. After the adjustment is completed, fix the first bidirectional lead screw 905 through the electromagnetic pin lock 12035 at one end of the first bidirectional lead screw 905. After the fixing is completed, rotate the second threaded rod 1303 to drive the U-shaped frame 1302 to slide, thereby adjusting the tension of the synchronous belt 5035.
