Description

[0001] The present invention relates to the technical field of ring part manufacturing, and particularly to a rapid repair device for the taper roller of a ring rolling mill. Background Art

[0002] Currently, with the development of industry, ring parts have become very common workpieces among components. During the manufacturing process of ring parts, especially for large ring parts, it is necessary to use a ring rolling mill for auxiliary production to improve the production efficiency of ring parts. The most important structure on the ring rolling mill is the taper roller, and the taper roller needs to be welded and repaired after long-term operation.

[0003] Currently, when repairing the taper roller of a ring rolling mill, since different taper rollers have different taper angles, it is necessary to measure the angle of the taper roller in advance and adjust the angle of the welding torch accordingly to ensure the welding quality. However, there are deviations when manually adjusting, and at the same time, the repair efficiency of the taper roller is reduced, thus affecting the production efficiency of ring parts.

Detailed implementation manners

[0035] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] It can be understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish one element from another.

[0037] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 8 、 Figure 10 and Figure 11 shown, in one embodiment, a rapid repair device for a conical roller of a ring rolling mill is proposed. The device includes four stations, namely a loading station a, a profiling station b, a welding station c and an unloading station d, and further includes:

[0038] Main body frame 1: It includes a mounting table 101 provided on the main body frame 1. The surface of the mounting table 101 is rotatably connected with a rotating plate 102. A plurality of support balls 103 are rotatably installed on the rotating plate 102. Four driving clamps 104 are fixedly installed on the surface of the rotating plate 102;

[0039] Extrusion mechanism 2: It includes four extrusion blocks 201 installed on the rotating plate 102. Both ends of each extrusion block 201 are respectively rotatably connected with a first connecting plate 204 and a second connecting plate 205. The other ends of the first connecting plate 204 and the second connecting plate 205 are rotatably connected with a linkage block 202. Connecting pulleys are fixedly installed on the rotating shafts of the extrusion block 201 and the linkage block 202. The first connecting plate 204 and the second connecting plate 205 are connected by a fixed shaft, and a fixing plate 206 is fixedly installed on the fixed shaft. A conical roller 207 to be repaired is arranged on the surface of the rotating plate 102. A welding torch head 203 is installed on the linkage block 202. A round hole matching the conical roller 207 to be repaired is opened on the rotating plate 102;

[0040] Transmission mechanism 3: It is used to drive the linkage block 202 to rotate synchronously with the extrusion block 201;

[0041] Welding mechanism 4: It is used to drive the welding torch head 203 to weld the conical roller 207 to be repaired;

[0042] Pushing mechanism 5: It is used to drive the extrusion block 201 to profile with the conical roller 207 to be repaired;

[0043] Self-rotation mechanism 6: It is used to drive the extrusion block 201 and the linkage block 202 to exchange positions.

[0044] In the actual application of the embodiment of the present invention, when welding the to-be-repaired taper roller 207, as Figure 3 and Figure 4 shown, place the to-be-repaired taper roller 207 on the support ball 103, and support the to-be-repaired taper roller 207 through the support ball 103. At this time, drive the clamp 104 to start moving to clamp the to-be-repaired taper roller 207. At this time, drive the rotating plate 102 to rotate under the action of an external drive. When moving from the loading station a to the profiling station b, as Figure 10 shown, at this time, through the action of the pushing mechanism 5, the extrusion block 201 approaches the to-be-repaired taper roller 207 and contacts the to-be-repaired taper roller 207. As the extrusion block 201 and the to-be-repaired taper roller 207 are extruded, at this time, the extrusion block 201 rotates, so as to fit and profile with the conical surface side of the to-be-repaired taper roller 207, as Figure 2 and Figure 8 shown. At the same time, drive the linkage block 202 to rotate synchronously in the reverse direction through the transmission of the transmission mechanism 3, and the rotation angles of the extrusion block 201 and the linkage block 202 are the same. At this time, when moving to the profiling station b, at this time, the extrusion block 201 and the linkage block 202 no longer move relative to each other under the action of the pushing mechanism 5. As the rotating plate 102 continues to rotate, when moving from the profiling station b to the welding station c, as Figure 11 shown, at this time, drive the fixed plate 206 to rotate by itself under the action of the self-rotation mechanism 6, so that the extrusion block 201 and the linkage block 202 switch positions. When switching positions, the position of the fixed plate 206 will not change under the limiting action of the pushing mechanism 5, avoiding motion interference, so as to achieve the purpose of fully welding the to-be-repaired taper roller 207 with different conical surface angles. At this time, after switching positions, the linkage block 202 moves to one side of the to-be-repaired taper roller 207. At the same time, the extrusion block 201 is reset under the action of the transmission mechanism 3. It should be noted here that the width of the extrusion block 201 is greater than the width of the linkage block 202. Therefore, after the extrusion block 201 and the linkage block 202 exchange positions, the linkage block 202 will not contact the conical surface of the to-be-repaired taper roller 207, thus ensuring the movement space of the welding torch head 203. Since the linkage block 202 is parallel to the conical surface of the to-be-repaired taper roller 207 at this time, drive the clamp 104 to drive the to-be-repaired taper roller 207 to rotate uniformly at the welding station c. At this time, the welding torch head 203 fully welds the surface of the to-be-repaired taper roller 207 under the action of the welding mechanism 4. When the welding is completed at the welding station c, at this time, the rotating plate 102 continues to revolve. During the process of moving from the welding station c to the unloading station d, reset the device through the self-rotation mechanism 6 and the pushing mechanism 5, so as to facilitate unloading at the unloading station d, thus achieving the purpose of cyclic welding.

[0045] As Figure 2 and Figure 8As shown, as a preferred embodiment of the present invention, the transmission mechanism 3 includes a main transmission belt 301 sleeved and connected to a connecting pulley located on the extrusion block 201. The other end of the main transmission belt 301 is sleeved on a transmission pulley 302. The transmission pulley 302 is connected to the first connecting plate 204 through a torsion spring 303. A transmission gear 304 is coaxially and fixedly installed on the surface of the transmission pulley 302. The transmission gear 304 meshes with a linkage ratchet gear 305. A driving bevel gear 306 is fixedly installed on the surface of the linkage ratchet gear 305. The driving bevel gear 306 is connected to a fixed plate 206 through a connecting spring. The driving bevel gear 306 meshes with a central bevel gear 307. The central bevel gear 307 meshes with a driven bevel gear 308. A driven pulley 310 is fixedly installed on the surface of the driven bevel gear 308. A secondary transmission belt 311 is sleeved on the surface of the driven pulley 310. The other end of the secondary transmission belt 311 is sleeved and connected to a connecting pulley located on the linkage block 202. A limiting gear 309 is fixedly installed on the surface of the driven bevel gear 308. The limiting gear 309 meshes with a limiting ratchet gear 312. The limiting ratchet gear 312 is connected to the fixed plate 206 through a compression spring 313. The transmission pulley 302, the transmission gear 304, the driving bevel gear 306, the driven bevel gear 308, and the driven pulley 310 are all coaxially and rotatably connected to a fixed shaft between the first connecting plate 204 and the second connecting plate 205.

[0046] In actual application of the embodiment of the present invention, when moving from the feeding station a to the profiling station b, at this time, the extrusion of the extrusion block 201 against the cone roller 207 to be repaired drives the extrusion block 201 to rotate. As Figure 2 and Figure 8 shown, the rotation of the extrusion block 201 drives the transmission pulley 302 to rotate through the connection of the synchronous belt. The rotation of the transmission pulley 302 drives the linkage ratchet gear 305 to rotate through the meshing of the gears, and then drives the driving bevel gear 306 to rotate. The rotation of the driving bevel gear 306 drives the driven bevel gear 308 to rotate through the transmission of the bevel gear set. Here, the direction of rotation is changed through the transmission of the bevel gear set. At this time, the driven bevel gear 308 is driven to rotate in the reverse direction, and then the linkage block 202 is driven to rotate in the opposite direction to the extrusion block 201 through the transmission of the gear and belt, so as to indirectly achieve the purpose of profiling the conical surface of the linkage block 202 with the cone roller 207 to be repaired. At the same time, during the rotation of the limiting gear 309, the rotation of the limiting gear 309 is limited by the limiting ratchet gear 312 to prevent it from resetting under the action of the connecting spring installed on the driving bevel gear 306. At the same time, through the connection of the transmission gear 304 and the linkage ratchet gear 305, when moving from the profiling station b to the welding station c, at this time, the extrusion block 201 and the linkage block 202 exchange positions under the action of the self-rotation mechanism 6. At this time, after the extrusion block 201 is separated from the reverse extrusion of the cone roller 207 to be repaired, it reversely resets under the action of the torsion spring 303, so as to achieve the function of automatic reset.

[0047] As shown in Figure 4 and Figure 5 As another preferred embodiment of the present invention, the welding mechanism 4 includes a welding motor 401 fixedly installed on the linkage block 202. The output end of the welding motor 401 penetrates through the linkage block 202 and is rotatably connected to the linkage block 202. A rotating lead screw 402 is fixedly installed at the output end of the welding motor 401. The rotating lead screw 402 forms a helical pair drive with a lead screw slider 403. The lead screw slider 403 is slidably connected to the inner wall of the linkage block 202. A welding torch head 203 is fixedly installed on the surface of the lead screw slider 403.

[0048] In the actual application of the embodiment of the present invention, as shown in Figure 4 and Figure 5 When moving to the welding station c, at this time, the linkage block 202 is parallel to the conical surface of the to-be-repaired taper roller 207. The welding motor 401 starts to move. The operation of the welding motor 401 drives the lead screw slider 403 to perform a linear motion on the linkage block 202 through the action of the helical pair drive, so as to drive the welding torch head 203 to fully weld the surface of the to-be-repaired taper roller 207.

[0049] As shown in Figure 4 , Figure 9 and Figure 10 As another preferred embodiment of the present invention, the pushing mechanism 5 includes a push rod 501 that penetrates through the rotating plate 102 and is slidably connected to the rotating plate 102. A tension spring 502 is fixedly installed on the surface of the push rod 501. The other end of the tension spring 502 is connected to a linkage slider 503. The push rod 501 is slidably connected to the linkage slider 503. A limiter is provided on the linkage slider 503. The linkage slider 503 is slidably connected to the inner wall of the rotating plate 102. A rotating rod 504 penetrates through the inside of the linkage slider 503 and is rotatably connected to the rotating rod 504. A fixing plate 206 is fixedly installed on the surface of the rotating rod 504. A centrifuge groove 505, an outer ring groove 506, a centripetal groove 507, and an inner ring groove 508 that are in cooperation with the push rod 501 and are sequentially connected end to end are formed inside the mounting table 101. The track radius of the centrifuge groove 505 gradually increases, and the track radius of the centripetal groove 507 gradually decreases.

[0050] In the actual application of the embodiment of the present invention, as shown in Figure 10 , when moving from the loading station a to the profiling station b, at this time, under the action of the track of the centrifuge groove 505, the push rod 501 is driven to move away from the central axis of the mounting table 101. As shown in Figure 4 , from Figure 4Looking from the front view direction, the movement of the push rod 501 drives the linkage slider 503 to move leftward by squeezing the tension spring 502. Then, through the connection of the mechanism, the rotating rod 504 drives the fixed plate 206 to move leftward. The fixed plate 206 drives the extrusion block 201 to come into contact and squeeze with the conical surface of the to-be-repaired taper roller 207. When the extrusion block 201 completes the profiling of the surface of the to-be-repaired taper roller 207, the continuous movement of the push rod 501 compresses the tension spring 502 at this time. When moving to the profiling station b, at this time, under the action of the limiter on the linkage slider 503, the position of the linkage slider 503 is fixed, so as to avoid the extrusion block 201 being disengaged from the to-be-repaired taper roller 207 when moving from the profiling station b to the welding station c, and the elastic potential energy of the tension spring 502 causes the position of the linkage slider 503 to change, resulting in a movement interference situation. When moving from the profiling station b to the welding station c, at this time, under the action of the outer ring groove 506, it will not drive the push rod 501 to move. When moving from the welding station c to the blanking station d after welding, at this time, under the action of the centripetal groove 507, it drives the push rod 501 to reset. At this time, when the elastic potential energy of the tension spring 502 disappears, the limiter resets, enabling the device to reset, thus ensuring the subsequent cyclic welding.

[0051] As Figure 11 shown, as another preferred embodiment of the present invention, the self-rotation mechanism 6 includes a self-rotation gear 601 coaxially and fixedly connected to the surface of the rotating rod 504. An external gear ring 602 and a centripetal gear ring 603 that cooperate with the self-rotation gear 601 are fixedly installed on the surface of the installation table 101, and the track radius of the centripetal gear ring 603 gradually decreases.

[0052] When the embodiment of the present invention is actually applied, as Figure 11 shown, when moving from the profiling station b to the welding station c, at this time, through the cooperation of the self-rotation gear 601 and the external gear ring 602, the self-rotation gear 601 is driven to rotate. The rotation of the self-rotation gear 601 drives the rotating rod 504 to rotate synchronously, and then drives the fixed plate 206 to rotate 180 degrees, so that the extrusion block 201 and the linkage block 202 are interchanged in position. When reaching the welding station c, the linkage block 202 is parallel to the conical surface of the to-be-repaired taper roller 207. At this time, the surface of the to-be-repaired taper roller 207 is fully welded through the action of the welding mechanism 4. When the welding is completed, the rotating plate 102 continues to rotate. At this time, through the cooperation of the self-rotation gear 601 and the centripetal gear ring 603, the self-rotation gear 601 is driven to reverse, so as to achieve the purpose of automatic reset. It should be noted here that due to the reset of the cooperation push mechanism 5 to avoid movement interference, the track radius of the centripetal gear ring 603 gradually decreases, thereby increasing the consistency of the device movement cooperation.

[0053] As Figure 4 、 Figure 6 、Figure 7 , Figure 8 and Figure 12 As shown in Figure 7 , Figure 8 and Figure 12 , as another preferred embodiment of the present invention, the device further includes a reset mechanism 7. The reset mechanism 7 includes a reset rod 701 slidably connected to the inner wall of the rotating rod 504. A reset step block 702 is fixedly installed on the surface of the reset rod 701. The surface of the reset step block 702 is provided with a ramp step with a smooth transition. The reset step block 702 is in contact with the thrust head 704. The thrust head 704 is fixedly installed on the thrust frame 703. The thrust frame 703 passes through the second connecting plate 205 and is slidably connected to the second connecting plate 205. The other end of the thrust frame 703 is connected to the surface of the limit ratchet gear 312. A track chute 705 and a protrusion groove 706 that cooperate with the reset rod 701 and are connected end to end in sequence are provided on the mounting table 101.

[0054] In the actual application of the embodiment of the present invention, when moving from the welding station c to the blanking station d, as shown in and

[0054] , Figure 4 and Figure 12 As shown in Figure 4 and Figure 12 , at this time, the cooperation of the reset rod 701 and the protrusion groove 706 drives the reset rod 701 to move upward. As shown in Figure 7 , Figure 7 as shown in Figure 7 From the front view direction of Figure 7 , the movement of the reset rod 701 drives the reset step block 702 to move upward. At this time, the extrusion of the ramp step on the reset step block 702 drives the thrust head 704 to move leftward, and then drives the thrust frame 703 to move leftward. As shown in Figure 8 , Figure 8 the movement of the thrust frame 703 drives the limit ratchet gear 312 to move leftward to compress the compression spring 313. At this time, the limit gear 309 is reset from the limiting effect of the limit ratchet gear 312, so as to achieve the purpose of automatic reset and facilitate cyclic welding.

[0055] As Figure 3 shown in Figure 3 , as another preferred embodiment of the present invention, the device further includes a driving mechanism 8. The driving mechanism 8 includes a driving motor 801 fixedly installed on the mounting table 101. The output end of the driving motor 801 passes through the mounting table 101 and is rotatably connected to the mounting table 101. A driving bevel gear 802 is fixedly installed at the output end of the driving motor 801. The driving bevel gear 802 meshes with a linkage bevel gear ring 803. The linkage bevel gear ring 803 is fixedly installed on the surface of the rotating plate 102.

[0056] In the actual application of the embodiment of the present invention, as shown in Figure 3 , Figure 3As shown, when welding the surface of the cone roller 207 to be repaired, the driving motor 801 starts to operate at this time.
