DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with 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 intended to limit the present invention.

[0018] It can be understood that the terms "first", "second", etc. used in the present application can be used in this article to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 , Fig.10 and Fig.11 As shown, in one embodiment, a quick repair device for a tapered roller of a ring rolling machine is proposed, the device comprises four stations: a loading station a, a profiling station b, a welding station c and a unloading station d, and further comprises: The main frame 1 comprises a mounting platform 101 arranged on the main frame 1, a rotating plate 102 is rotatably connected to the surface of the mounting platform 101, a plurality of supporting balls 103 are rotatably mounted on the rotating plate 102, and four driving clamps 104 are fixedly mounted on the surface of the rotating plate 102; Extrusion mechanism 2: comprising four extrusion blocks 201 mounted on the rotating plate 102, both ends of each extrusion block 201 are rotatably connected to the first connecting plate 204 and the second connecting plate 205 respectively, the other ends of the first connecting plate 204 and the second connecting plate 205 are rotatably connected to the linkage block 202, connecting pulleys are fixedly mounted on the rotating shafts of the extrusion blocks 201 and the linkage blocks 202, the first connecting plate 204 and the second connecting plate 205 are connected via a fixed shaft, and the fixed plate 206 is fixedly mounted on the fixed shaft, a cone roller 207 to be repaired is arranged on the surface of the rotating plate 102, a welding gun head 203 is installed on the linkage block 202, and a circular hole matching the cone roller 207 to be repaired is opened on the rotating plate 102; Transmission mechanism 3: used to drive the linkage block 202 to rotate synchronously with the extrusion block 201; Welding mechanism 4: used to drive the welding gun head 203 to weld the cone roller 207 to be repaired; Pushing mechanism 5: used to drive the extrusion block 201 and the cone roller 207 to be repaired to perform profiling; Rotation mechanism 6: used to drive the extrusion block 201 and the linkage block 202 to exchange positions.

[0020] In practical application of the embodiment of the present invention, when welding the cone roller 207 to be repaired, Figure 3 and Figure 4 As shown, the cone roller 207 to be repaired is placed on the support ball 103, and the cone roller 207 to be repaired is supported by the support ball 103. At this time, the driving clamp 104 starts to move to clamp the cone roller 207 to be repaired. At this time, the rotating plate 102 is driven to rotate under the external driving action. When it moves from the loading station a to the profiling station b, as shown in FIG. Fig.10As shown, at this time, the extrusion block 201 is moved close to the cone roller 207 to be repaired and contacts the cone roller 207 to be repaired by the action of the pushing mechanism 5. As the extrusion block 201 and the cone roller 207 to be repaired are squeezed, the extrusion block 201 is rotated to conform to the conical surface side of the cone roller 207 to be repaired, as shown in FIG. Figure 2 and Figure 8 As shown, the linkage block 202 is driven by the transmission mechanism 3 to rotate in the opposite direction synchronously, and the extrusion block 201 and the linkage block 202 have the same rotation angle. When the extrusion block 201 and the linkage block 202 move to the profiling station b, 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 the extrusion block 201 moves to the welding station c from the profiling station b, as shown in FIG. Fig.11 As shown, at this time, the fixed plate 206 is driven to rotate under the action of the self-rotating 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, thereby achieving the purpose of fully welding the cone roller 207 to be repaired with different cone surface angles. At this time, after switching positions, the linkage block 202 moves to one side of the cone roller 207 to be repaired, and 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 2 02 will not contact the conical surface of the cone roller 207 to be repaired, thereby ensuring the movement space of the welding gun head 203. Since the linkage block 202 is parallel to the conical surface of the cone roller 207 to be repaired at this time, the driving clamp 104 synchronously drives the cone roller 207 to be repaired to rotate at a uniform speed at the welding station c. At this time, the welding gun head 203 fully welds the surface of the cone roller 207 to be repaired under the action of the welding mechanism 4. When the welding is completed at the welding station c, the rotating plate 102 continues to revolve. In the process of moving from the welding station c to the unloading station d, the device is reset by the rotation mechanism 6 and the pushing mechanism 5, which facilitates unloading at the unloading station d, thereby achieving the purpose of cyclic welding.

[0021] like Figure 2 and Figure 8As shown, as a preferred embodiment of the present invention, the transmission mechanism 3 includes a main transmission belt 301 which is located on the extrusion block 201 and is sleeved with a connecting pulley. 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 fixedly installed on the surface of the transmission pulley 302. The transmission gear 304 is meshed with a linkage ratchet gear 305. An active bevel gear 306 is fixedly installed on the surface of the linkage ratchet gear 305. The active bevel gear 306 is connected to the fixed plate 206 through a connecting spring. The active bevel gear 306 is meshed with a center bevel tooth 307. The center bevel tooth 307 is meshed with the slave The driven bevel gear 308 is meshed with each other, and 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 the connecting pulley located on the linkage block 202. A limit gear 309 is fixedly installed on the surface of the driven bevel gear 308. The limit gear 309 is meshed with a limit ratchet gear 312. The limit ratchet gear 312 is connected to the fixed plate 206 through a compression spring 313. The transmission pulley 302, the transmission gear 304, the active bevel gear 306, the driven bevel gear 308 and the driven pulley 310 are all coaxially rotatably connected with the fixed axis between the first connecting plate 204 and the second connecting plate 205.

[0022] In actual application, when the embodiment of the present invention moves from the loading station a to the profiling station b, the extrusion of the extrusion block 201 and the cone roller 207 to be repaired drives the extrusion block 201 to rotate, such as Figure 2 and Figure 8 As shown, the rotation of the extrusion block 201 drives the transmission pulley 302 to rotate through the synchronous belt connection, and the rotation of the transmission pulley 302 drives the linkage ratchet gear 305 to rotate through the gear meshing action, thereby driving the active bevel gear 306 to rotate, and the rotation of the active bevel gear 306 drives the driven bevel gear 308 to rotate through the transmission action of the bevel gear set. Here, the direction of rotation is changed by the transmission of the bevel gear set, and the driven bevel gear 308 is driven to rotate in the opposite 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 toothed belt, thereby indirectly making the linkage block 202 and the extrusion block 201 rotate. For the purpose of profiling the conical surface of the cone roller 207 to be repaired, during the rotation of the limit gear 309, the limit gear 309 is limited in rotation by the limit ratchet gear 312 to avoid resetting under the action of the connecting spring installed on the active bevel gear 306. At the same time, through the connection between the transmission gear 304 and the linkage ratchet gear 305, when moving from the profiling station b to the welding station c, the extrusion block 201 and the linkage block 202 exchange positions under the action of the 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 is reversed and reset under the action of the torsion spring 303, thereby achieving the function of automatic resetting.

[0023] like Figure 4 and Figure 5 As shown, as another preferred embodiment of the present invention, the welding mechanism 4 includes a welding motor 401 fixedly mounted on the linkage block 202, the output end of the welding motor 401 passes through the linkage block 202 and is rotatably connected to the linkage block 202, a rotating screw 402 is fixedly mounted on the output end of the welding motor 401, the rotating screw 402 and the screw slider 403 form a spiral pair transmission, the screw slider 403 is slidably connected to the inner wall of the linkage block 202, and a welding gun head 203 is fixedly mounted on the surface of the screw slider 403.

[0024] In practical application, the embodiment of the present invention is as follows: Figure 4 and Figure 5 As shown, when it moves to the welding station c, the linkage block 202 is parallel to the conical surface of the cone roller 207 to be repaired, and the welding motor 401 starts to move. The operation of the welding motor 401 drives the screw slider 403 to move linearly on the linkage block 202 through the spiral pair transmission action, thereby driving the welding gun head 203 to fully weld the surface of the cone roller 207 to be repaired.

[0025] like Figure 4 , Fig. 9 and Fig.10 As shown, as another preferred embodiment of the present invention, the pushing mechanism 5 includes a pushing rod 501 that passes 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 pushing rod 501, and the other end of the tension spring 502 is connected to the linkage slider 503, the pushing rod 501 is slidably connected to the linkage slider 503, a limiter is arranged 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 passes through the interior of the linkage slider 503 and is rotatably connected to the rotating rod 504, a fixed plate 206 is fixedly installed on the surface of the rotating rod 504, and a distal groove 505, an outer ring groove 506, a proximal groove 507 and an inner ring groove 508 that cooperate with the pushing rod 501 and are sequentially connected end to end are provided inside the mounting platform 101, and the trajectory radius of the distal groove 505 gradually increases, and the trajectory radius of the proximal groove 507 gradually decreases.

[0026] In practical application, the embodiment of the present invention is as follows: Fig.10 As shown, when moving from the loading station a to the profiling station b, the push rod 501 is driven to move away from the central axis of the mounting platform 101 under the action of the trajectory of the telecentric groove 505, as shown in FIG. Figure 4 As shown, from Figure 4When viewed from the front, the movement of the push rod 501 drives the linkage slider 503 to move leftward through the extrusion and tension spring 502, and then drives the fixed plate 206 to move leftward through the rotating rod 504 through the connection of the mechanism, and the fixed plate 206 drives the extrusion block 201 to contact and extrude the conical surface of the cone roller 207 to be repaired. When the extrusion block 201 rotates to complete the surface profiling of the cone roller 207 to be repaired, the push rod 501 continues to move to compress the tension spring 502. When it moves to the profiling station b, the position of the linkage slider 503 is fixed under the action of the upper limiter of the linkage slider 503, thereby avoiding the profiling station b. When it moves to welding station c, the extrusion block 201 is out of contact with the cone roller 207 to be repaired, and the elastic potential energy of the stretch spring 502 causes the position of the linkage slider 503 to change, resulting in motion interference. When it moves from the profiling station b to the welding station c, the outer ring groove 506 does not drive the push rod 501 to move. When welding is completed and it moves from the welding station c to the blanking station d, the proximal groove 507 drives the push rod 501 to reset. At this time, when the elastic potential energy of the stretch spring 502 disappears, the limiter is reset, so that the device is reset, thereby ensuring the subsequent cycle welding.

[0027] like Fig.11 As shown, as another preferred embodiment of the present invention, the rotation mechanism 6 includes a rotation gear 601 coaxially fixedly connected to the surface of the rotating rod 504, and the surface of the mounting platform 101 is fixedly mounted with an outer gear ring 602 and a proximal gear ring 603 that match the rotation gear 601, and the trajectory radius of the proximal gear ring 603 gradually decreases.

[0028] In practical application, the embodiment of the present invention is as follows: Fig.11 As shown, when moving from the profiling station b to the welding station c, the self-rotating gear 601 is driven to rotate by the cooperation of the self-rotating gear 601 and the outer gear ring 602. The rotation of the self-rotating 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 exchange positions. When arriving at the welding station c, the linkage block 202 is parallel to the conical surface of the cone roller 207 to be repaired. At this time, the surface of the cone roller 207 to be repaired is fully welded by the action of the welding mechanism 4. When the welding is completed, the rotating plate 102 continues to rotate. At this time, the self-rotating gear 601 is driven to reverse by the cooperation of the self-rotating gear 601 and the proximal gear ring 603, thereby achieving the purpose of automatic resetting. It should be noted here that due to the reset of the cooperative pushing mechanism 5, motion interference is avoided, so the trajectory radius of the proximal gear ring 603 is gradually reduced, thereby increasing the consistency of the motion coordination of the device.

[0029] like Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig.12 As shown, as another preferred embodiment of the present invention, the device also 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 column head 704, the thrust column 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 limiting ratchet gear 312, and the mounting table 101 is provided with a track groove 705 and a protruding groove 706 that cooperate with the reset rod 701 and are sequentially connected end to end.

[0030] In practical application of the embodiment of the present invention, when moving from welding station c to blanking station d, as shown in FIG. Figure 4 and Fig.12 As shown, at this time, the reset rod 701 is driven to move upward by the cooperation of the reset rod 701 and the protruding groove 706, as shown in FIG. Figure 7 As shown, from Figure 7 From the front view direction, the movement of the reset rod 701 drives the reset step block 702 to move upward. At this time, the thrust column head 704 is driven to move leftward by the squeezing effect of the ramp step on the reset step block 702, thereby driving the thrust frame 703 to move leftward. Figure 8 As shown, the movement of the thrust frame 703 drives the limiting ratchet gear 312 to move leftward to compress the compression spring 313. At this time, the limiting gear 309 is separated from the limiting effect of the limiting ratchet gear 312 and resets, thereby achieving the purpose of automatic reset and facilitating cyclic welding.

[0031] like Figure 3 As shown, as another preferred embodiment of the present invention, the device also includes a driving mechanism 8, the driving mechanism 8 includes a driving motor 801 fixedly mounted on the mounting platform 101, the output end of the driving motor 801 passes through the mounting platform 101 and is rotatably connected to the mounting platform 101, and a driving bevel gear 802 is fixedly mounted on the output end of the driving motor 801, the driving bevel gear 802 is meshed with a linkage bevel gear ring 803, and the linkage bevel gear ring 803 is fixedly mounted on the surface of the rotating plate 102.

[0032] In practical application, the embodiment of the present invention is as follows: Figure 3As shown, when welding is performed on the surface of the cone roller 207 to be repaired, the drive motor 801 starts to run, and the operation of the drive motor 801 drives the drive bevel gear 802 to rotate, and then drives the rotating plate 102 to rotate through the transmission action of the bevel gear, so that the cone roller 207 to be repaired performs a cyclic motion in the four stations of loading station a, profiling station b, welding station c, and unloading station d, thereby improving the welding efficiency of the cone roller 207 to be repaired.
