Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, and in particular to an automatic processing device for a bearing outer ring. Background Art

[0002] Bearings are important parts in modern mechanical equipment, among which rolling bearings mainly play the role of supporting rotation, reducing the friction coefficient of the movement process, and ensuring the rotation accuracy. Rolling bearings mainly limit the inner and outer rings of the bearings to the balls or rollers to achieve the function of free rotation of the inner and outer rings, among which the outer ring plays an important supporting role; the outer ring of the bearing is usually made of cast steel, steel ingots or forged blanks, and can also be made of cold-rolled or cold-drawn steel pipe materials. When preparing the blank, it is usually necessary to select the appropriate material according to the inner and outer diameters, width and other dimensional requirements of the outer ring. The processing of the outer ring of the bearing requires multiple processes, among which the most important is rough processing, which is usually completed using a lathe, milling machine or CNC machine tool, and is specifically divided into end turning, inner hole turning, etc.; the bearing outer ring processing device in the prior art is usually unable to realize the automatic processing of the two end faces and inner hole of the bearing outer ring, and the degree of automation is insufficient. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is as follows: an automatic bearing outer ring processing device, comprising a main body mechanism, the main body mechanism comprising a bottom plate, the main body mechanism is provided with two self-rotating mechanisms for cooperating with the main body mechanism to process metal raw materials, the self-rotating mechanism comprises a fixed seat, the fixed seat is fixedly mounted on the bottom plate, a rotating seat is rotatably mounted on the fixed seat, a top gear is fixedly mounted on the rotating seat, the self-rotating mechanism is provided with a clamping mechanism for clamping the metal raw material, the clamping mechanism comprises a clamping plate; The main mechanism comprises a periodic lever, on which a toggle head is fixedly mounted, and a toggle wheel is fixedly mounted on a rotating seat of the rotation mechanism close to one side of the periodic lever, the toggle head cooperates with the toggle wheel, and the top gears of the two rotation mechanisms mesh with each other.

[0004] Furthermore, the main body mechanism also includes a motor frame fixedly mounted on the bottom plate, a periodic motor is fixedly mounted on the motor frame, a periodic shifting rod is fixedly mounted on the motor shaft of the periodic motor, and a vertical pole is fixedly mounted on the bottom plate.

[0005] Furthermore, a lifting electric cylinder is fixedly installed on the base plate, a lifting frame is fixedly installed on the output end of the lifting electric cylinder, the lifting frame is slidably installed with the vertical pole, the lifting frame is slidably installed with the fixed seat, two sets of tool modules are fixedly installed on the lifting frame, the tool modules include an external turning tool, a grinding tool and a lifting triangle block, and the two sets of tool modules are respectively located around the two rotating mechanisms.

[0006] Furthermore, a rotating rod is rotatably installed on the lifting frame, an extension column is slidably installed on the vertical rod, an extension frame is fixedly installed on the extension column, the extension frame is rotatably installed with the rotating rod, left and right sliders are slidably installed on the extension frame, an inner turning tool is fixedly installed on the left and right sliders, and a track frame is fixedly installed on the vertical rod.

[0007] Furthermore, the track frame is composed of an expansion section, a deepening section, a reset section, a return section and an initial section. Guide posts are fixedly installed on the left and right sliders. The guide posts slide in the track frame. When the guide posts move, the guide posts first enter the initial section, and then enter the expansion section, the deepening section, and the reset section, and then return to the initial section through the return section and then return to the initial position.

[0008] The metal material is clamped by the clamping mechanism of the self-rotating mechanism close to one side of the vertical pole, and the metal material is driven to rotate by the self-rotating mechanism. The periodic motor controls the periodic lever to rotate. When the toggle head enters the groove of the toggle wheel, it will drive the toggle wheel, the top gear and the rotating seat to rotate 90 degrees. Due to the meshing of the two top gears, the rotation directions of the two rotating seats are opposite. Then the toggle head is separated from the toggle wheel to realize the intermittent rotation of the rotating seat and the top gear, and each time it rotates 90 degrees, the lifting electric cylinder retracts and contracts once each time the rotating seat rotates, and the lifting electric cylinder extends The lifting frame is driven to rise, thereby driving the outer turning tool, grinding tool and lifting triangle block to rise, and at the same time driving the rotating rod to rotate. When the metal raw material is located above the outer turning tool, the outer turning tool rises and cooperates with the self-rotation of the metal raw material to cut the metal raw material into a specified length. When the metal raw material is located above the grinding tool, the grinding tool rises and cooperates with the self-rotation of the metal raw material to grind the cut surface of the metal raw material. When the metal raw material is located in front of the inner turning tool, the rotating rod rotates to drive the extension frame and the extension column to slide back and forth, so that the extension frame moves to the farthest point toward the metal raw material and then slides inward. The guide column first moves along The initial section enters the expansion section. At this time, the inner turning tool cooperates with the self-rotation of the metal raw material to perform preliminary cutting of the inner ring, and cooperates with the sliding of the left and right sliders relative to the extension frame. Then the guide column reaches the deep section along the expansion section. At this time, the inner turning tool expands the inner ring of the metal raw material, so that the inner ring cutting of the metal raw material is completed. Then the guide column reaches the farthest point along the reset section, and then the guide column returns to the initial position along the return section and the initial section. When the metal raw material reaches the top of the lifting triangle block on the vertical pole side, the fixed seat of the clamping mechanism on the self-rotation mechanism on the motor frame side is just located on the metal raw material. In front, at this time, the metal raw material stops rotating, and the lifting triangle block rises so that the clamping mechanism on the rotation mechanism on the vertical pole side releases the clamping of the metal raw material, and pops the metal raw material onto the clamping mechanism of the rotation mechanism on the motor frame side, and is clamped by the clamping mechanism on the motor frame side. Subsequently, the end face of the other end of the metal raw material is cut and polished in the same way through the rotation mechanism on the motor frame side. When the metal raw material moves to the lifting triangle block on the motor frame side, the lifting triangle block rises to unlock the clamping mechanism, and the processed metal raw material is ejected to complete the processing.

[0009] Furthermore, the clamping mechanism includes three clamping claws rotatably mounted on a clamping plate, a top column is slidably mounted on the clamping plate, a top plate and a lower pressure plate are fixedly mounted on the top column, three clamping links are rotatably mounted on the lower pressure plate, the clamping links and the clamping claws are rotatably mounted, a clamping spring is arranged between the lower pressure plate and the clamping plate, and the elastic force of the clamping spring of the clamping mechanism on the rotation mechanism on the vertical pole side is greater than the elastic force of the clamping spring of the clamping mechanism on the rotation mechanism on the motor frame side.

[0010] Furthermore, a lifting seat is fixedly installed on the clamping plate, a clamping column is slidably installed on the lifting seat, a clamping column spring is arranged between the clamping column and the lifting seat, an outer sliding clamping frame is slidably installed on the clamping plate, a slope is arranged on the outer sliding clamping frame, an outward push connecting rod is rotatably installed on the outer sliding clamping frame, and the outward push connecting rod is rotatably installed with the lower pressure plate.

[0011] When clamping the metal raw material, the metal raw material is inserted between the four clamping claws, and the top plate is pushed inward by the metal raw material, driving the top column and the lower pressure plate to slide toward the clamping plate, and the clamping spring is compressed, thereby driving the clamping connecting rod to rotate, and the clamping connecting rod drives the three clamping claws to rotate inward, and the metal raw material is clamped by the three clamping claws. At the same time, the lower pressure plate will drive the outward push connecting rod to rotate, thereby driving the outer sliding bracket to slide outward, and the outer sliding bracket will lift the clamping column through the slope thereon, and the clamping column spring is compressed. When the slope of the outer sliding bracket passes through the clamping column, the clamping column spring rebounds, and the clamping column reaches the rear of the outer sliding bracket. At this time, the outer sliding bracket is locked by the clamping column, thereby stabilizing the position of the lower pressure plate, so that the clamping spring cannot rebound, so that the clamping claws keep clamping the metal raw material.

[0012] When the metal raw material reaches the top of the lifting triangle block on one side of the vertical rod, the clamping column is located at the lower position on the clamping plate, and the lifting triangle block rises and contacts with the clamping column, thereby driving the clamping column to slide along the lifting seat, the clamping column spring is compressed, and the clamping column releases the clamping of the outer sliding clamping frame. At this time, the clamping spring rebounds, driving the lower pressure plate to rise, driving the outer sliding clamping frame to slide inward through the outward pushing connecting rod, and driving the clamping claws to open outward through the clamping connecting rod, releasing the clamping of the metal raw material. At the same time, the top plate pops out outward under the rebound action of the clamping spring, and the metal raw material is bounced onto the top plate of the clamping mechanism on the rotating mechanism on the motor frame side. Because the elastic force of the clamping spring of the clamping mechanism on the rotating mechanism on the vertical rod side is greater than the elastic force of the clamping spring of the clamping mechanism on the rotating mechanism on the motor frame side, the metal raw material will cause the top plate to be squeezed inward, thereby driving the lower pressure plate to slide inward, and in the same steps, the clamping mechanism on the rotating mechanism on the motor frame side clamps the metal raw material, thereby realizing the transfer of the metal raw material between the two clamping mechanisms.

[0013] Furthermore, the self-rotation mechanism includes a self-rotating motor fixedly mounted on a fixed seat, a motor gear fixedly mounted on the motor shaft of the self-rotating motor, a docking gear rotatably mounted on the fixed seat, the docking gear meshing with the motor gear, a gear shaft rotatably mounted in the fixed seat, a lower gear and an upper bevel gear fixedly mounted on the gear shaft, the lower gear meshing with the docking gear, a rotating shaft rotatably mounted on the rotating seat, a side bevel gear fixedly mounted on the rotating shaft, the side bevel gear meshing with the upper bevel gear, and a clamping plate fixedly mounted on the rotating shaft.

[0014] Furthermore, an inner rotating ring is arranged below the rotating seat, an insertion groove is arranged on the inner rotating ring, four clamping blocks are slidably installed in the fixed seat, a clamping block spring is arranged between the clamping block and the fixed seat, and the clamping block cooperates with the insertion groove on the inner rotating ring.

[0015] The self-rotating motor controls the rotation of the motor gear, which drives the lower gear, gear shaft and upper bevel gear to rotate through the docking gear, thereby driving the side bevel gear, rotating shaft and clamping plate to rotate, thereby driving the metal raw material to rotate, and clamping the inner rotating ring through the clamping block, so that when the toggle head is not located in the toggle wheel, the relative position of the rotating seat and the fixed seat remains stable.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) The clamping mechanism provided in the present invention can realize automatic clamping and locking of the metal raw material, ensuring that it remains stable during subsequent processing, and drives the metal raw material to rotate through the self-rotation mechanism, and cooperates with multiple tool heads to automatically process the end face and the inner hole, with high processing stability; (2) The self-rotation mechanism provided in the present invention cooperates with the clamping mechanism to drive the metal raw material to perform end face cutting, end face grinding, inner hole processing and reversing, etc., and all actions are automatically and continuously performed, with a high degree of automation and good continuity; (3) The left and right slide blocks and the inner turning tool provided in the present invention follow the guide column to slide in each track section in the track frame, so as to first drill from the end of the metal raw material and gradually expand the hole outward, so that the inner hole processing effect is good and the risk of tool breakage is reduced.

[0033] like Figure 2-Figure 5 As shown, a lifting electric cylinder 107 is fixedly installed on the base plate 101, a lifting frame 108 is fixedly installed on the output end of the lifting electric cylinder 107, the lifting frame 108 is slidably installed with the vertical rod 112, the lifting frame 108 is slidably installed with the fixed seat 301, and two sets of tool modules are fixedly installed on the lifting frame 108, the tool modules include an external turning tool 109, a grinding tool 110 and a lifting triangle block 111, and the two sets of tool modules are respectively located around the two rotating mechanisms.

[0034] like Figure 2-Figure 5 As shown, a rotating rod 113 is rotatably mounted on the lifting frame 108, an extending column 115 is slidably mounted on the vertical rod 112, an extending frame 114 is fixedly mounted on the extending column 115, the extending frame 114 is rotatably mounted with the rotating rod 113, left and right sliders 116 are slidably mounted on the extending frame 114, an inner turning tool 118 is fixedly mounted on the left and right sliders 116, and a track frame 117 is fixedly mounted on the vertical rod 112.

[0035] like Figure 2-Figure 5As shown, the track frame 117 is composed of an expansion section 1171, a penetration section 1172, a reset section 1173, a return section 1174 and an initial section 1175. Guide posts 119 are fixedly installed on the left and right sliders 116. The guide posts 119 slide in the track frame 117. When the guide posts 119 move, the guide posts 119 first enter the initial section 1175, and then enter the expansion section 1171, the penetration section 1172, and the reset section 1173, and return to the initial section 1175 through the return section 1174 and then return to the initial position.

[0036] The metal material 4 is clamped by the clamping mechanism of the self-rotating mechanism near the side of the vertical rod 112, and the metal material 4 is driven to rotate by the self-rotating mechanism. The periodic motor 103 controls the periodic lever 104 to rotate. When the toggle head 105 enters the groove of the toggle wheel 106, it will drive the toggle wheel 106, the top gear 303 and the rotating seat 302 to rotate ninety degrees. Due to the meshing of the two top gears 303, the rotation directions of the two rotating seats 302 are opposite. Then the toggle head 105 is disengaged from the toggle wheel 106, realizing the intermittent rotation of the rotating seat 302 and the top gear 303, and each time it rotates ninety degrees, each time the rotating seat 302 rotates once, the lifting electric cylinder 107 is extended and retracted once, and the lifting electric cylinder 107 The extension drives the lifting frame 108 to rise, thereby driving the outer turning tool 109, the grinding tool 110 and the lifting triangle block 111 to rise, and at the same time drives the rotating rod 113 to rotate. When the metal raw material 4 is located above the outer turning tool 109, the outer turning tool 109 rises to cooperate with the self-rotation of the metal raw material 4 to cut the metal raw material 4 into a specified length. When the metal raw material 4 is located above the grinding tool 110, the grinding tool 110 rises to cooperate with the self-rotation of the metal raw material 4 to grind the cut surface of the metal raw material 4. When the metal raw material 4 is located in front of the inner turning tool 118, the rotating rod 113 rotates to drive the extension frame 114 and the extension column 115 to slide back and forth, so that the extension frame 114 moves to the farthest point toward the metal raw material 4 and then slides inward, and the guide column 115 moves to the farthest point. 19 first enters the expansion section 1171 along the initial section 1175, at which time the inner turning tool 118 cooperates with the self-rotation of the metal raw material 4 to perform preliminary cutting of the inner ring, and cooperates with the sliding of the left and right sliders 116 relative to the extension frame 114, and then the guide column 119 reaches the deep section 1172 along the expansion section 1171. At this time, the inner turning tool 118 expands the inner ring of the metal raw material 4, so that the inner ring cutting of the metal raw material 4 is completed, and then the guide column 119 reaches the farthest point along the reset section 1173, and then the guide column 119 returns to the initial position along the return section 1174 and the initial section 1175. When the metal raw material 4 reaches the top of the jacking triangle block 111 on the side of the vertical rod 112, at this time, the rotation mechanism on the side of the motor frame 102 The fixed seat 301 of the clamping mechanism is just located in front of the metal raw material 4. At this time, the metal raw material 4 stops rotating, and the lifting triangle block 111 rises so that the clamping mechanism on the rotation mechanism on the side of the vertical pole 112 releases the clamping of the metal raw material 4, and the metal raw material 4 is ejected onto the clamping mechanism of the rotation mechanism on the side of the motor frame 102, and is clamped by the clamping mechanism on the side of the motor frame 102. Subsequently, the end surface of the other end of the metal raw material 4 is cut and polished in the same way through the rotation mechanism on the side of the motor frame 102. When the metal raw material 4 moves to the lifting triangle block 111 on the side of the motor frame 102, the lifting triangle block 111 rises so that the clamping mechanism is unlocked, and the processed metal raw material 4 is ejected to complete the processing.

[0037] like Figure 6-Figure 9As shown, the clamping mechanism includes three clamping claws 202 rotatably mounted on a clamping plate 201, a top column 204 is slidably mounted on the clamping plate 201, a top plate 203 and a lower pressure plate 205 are fixedly mounted on the top column 204, three clamping links 206 are rotatably mounted on the lower pressure plate 205, the clamping links 206 are rotatably mounted with the clamping claws 202, a clamping spring 212 is arranged between the lower pressure plate 205 and the clamping plate 201, and the elastic force of the clamping spring 212 of the clamping mechanism on the rotation mechanism on the vertical pole 112 side is greater than the elastic force of the clamping spring 212 of the clamping mechanism on the rotation mechanism on the motor frame 102 side.

[0038] like Figure 6-Figure 9 As shown, a lifting seat 209 is fixedly installed on the clamping plate 201, a clamping column 210 is slidably installed on the lifting seat 209, a clamping column spring 211 is arranged between the clamping column 210 and the lifting seat 209, an outer sliding bracket 208 is slidably installed on the clamping plate 201, a slope is arranged on the outer sliding bracket 208, an outward push connecting rod 207 is rotatably installed on the outer sliding bracket 208, and the outward push connecting rod 207 is rotatably installed with the lower pressure plate 205.

[0039] When clamping the metal raw material 4, the metal raw material 4 is inserted between the four clamping jaws 202, and the top plate 203 is pushed inward by the metal raw material 4, driving the top column 204 and the lower pressure plate 205 to slide toward the clamping plate 201, and the clamping spring 212 is compressed, thereby driving the clamping link 206 to rotate, and the clamping link 206 drives the three clamping jaws 202 to rotate inward, and the metal raw material 4 is clamped by the three clamping jaws 202, and at the same time, the lower pressure plate 205 drives the push-out link 207 to rotate, so that The outer sliding bracket 208 is driven to slide outward, and the outer sliding bracket 208 lifts the clamping column 210 through the slope thereon, and the clamping column spring 211 is compressed. When the slope of the outer sliding bracket 208 passes the clamping column 210, the clamping column spring 211 rebounds, and the clamping column 210 reaches the rear of the outer sliding bracket 208. At this time, the outer sliding bracket 208 is locked by the clamping column 210, thereby stabilizing the position of the lower pressure plate 205, so that the clamping spring 212 cannot rebound, so that the clamping claw 202 keeps clamping the metal raw material 4.

[0040] When the metal raw material 4 reaches the top of the lifting triangle block 111 located on one side of the vertical rod 112, the clamping column 210 is located at the lower position on the clamping plate 201. The lifting triangle block 111 rises and contacts with the clamping column 210, thereby driving the clamping column 210 to slide along the lifting seat 209, and the clamping column spring 211 is compressed. The clamping column 210 releases the clamping of the outer sliding bracket 208. At this time, the clamping spring 212 rebounds, driving the lower pressure plate 205 to rise, and driving the outer sliding bracket 208 to slide inwardly through the outward push connecting rod 207. At the same time, the clamping claw 202 is driven to open outward through the clamping connecting rod 206, thereby releasing the clamping of the metal raw material 4. At the same time, the top plate 203 is in the clamping The metal raw material 4 is ejected outwards by the rebound action of the holding spring 212, and is ejected onto the top plate 203 of the clamping mechanism on the rotating mechanism on the motor frame 102 side. Since the elastic force of the clamping spring 212 of the clamping mechanism on the rotating mechanism on the vertical pole 112 side is greater than the elastic force of the clamping spring 212 of the clamping mechanism on the rotating mechanism on the motor frame 102 side, the metal raw material 4 will cause the top plate 203 to be squeezed inwards, thereby driving the lower pressure plate 205 to slide inwards. The same steps are used to enable the clamping mechanism on the rotating mechanism on the motor frame 102 side to clamp the metal raw material 4, thereby realizing the transfer of the metal raw material 4 between the two clamping mechanisms.

[0041] like Figure 10-12 As shown, the rotation mechanism includes a rotation motor 304 fixedly mounted on a fixed seat 301, a motor gear 305 fixedly mounted on the motor shaft of the rotation motor 304, a docking gear 306 rotatably mounted on the fixed seat 301, the docking gear 306 meshes with the motor gear 305, a gear shaft 308 rotatably mounted in the fixed seat 301, a lower gear 309 and an upper bevel gear 313 fixedly mounted on the gear shaft 308, the lower gear 309 meshes with the docking gear 306, a rotating shaft 314 rotatably mounted on the rotating seat 302, a side bevel gear 307 fixedly mounted on the rotating shaft 314, the side bevel gear 307 meshes with the upper bevel gear 313, and the clamping plate 201 is fixedly mounted on the rotating shaft 314.

[0042] like Figure 10-12 As shown, an inner rotating ring 312 is provided below the rotating seat 302, an insertion groove is provided on the inner rotating ring 312, four clamping blocks 310 are slidably installed in the fixed seat 301, a clamping block spring 311 is provided between the clamping block 310 and the fixed seat 301, and the clamping block 310 cooperates with the insertion groove on the inner rotating ring 312.

[0043] The self-rotating motor 304 controls the motor gear 305 to rotate, and drives the lower gear 309, the gear shaft 308 and the upper bevel gear 313 to rotate through the docking gear 306, thereby driving the side bevel gear 307, the rotating shaft 314 and the clamping plate 201 to rotate, thereby driving the metal raw material 4 to rotate, and the inner rotating ring 312 is clamped by the clamping block 310, so that when the toggle head 105 is not located in the toggle wheel 106, the relative position of the rotating seat 302 and the fixed seat 301 remains stable.

[0044] The working principle of the automatic processing device for the outer ring of a bearing disclosed in the present invention is as follows: when clamping the metal raw material 4, the metal raw material 4 is inserted between the four clamping claws 202, and the top plate 203 is pushed inward by the metal raw material 4, driving the top column 204 and the lower pressure plate 205 to slide toward the clamping plate 201, and the clamping spring 212 is compressed, thereby driving the clamping connecting rod 206 to rotate, and the clamping connecting rod 206 drives the three clamping claws 202 to rotate inward, and the metal raw material 4 is clamped by the three clamping claws 202, and at the same time the lower pressure plate 205 will drive The push-out connecting rod 207 rotates, thereby driving the outer sliding bracket 208 to slide outward. The outer sliding bracket 208 lifts the clamping column 210 through the slope thereon, and the clamping column spring 211 is compressed. When the slope of the outer sliding bracket 208 passes the clamping column 210, the clamping column spring 211 rebounds, and the clamping column 210 reaches the rear of the outer sliding bracket 208. At this time, the outer sliding bracket 208 is locked by the clamping column 210, thereby stabilizing the position of the lower pressure plate 205, so that the clamping spring 212 cannot rebound, so that the clamping claw 202 keeps clamping the metal raw material 4. The self-rotating motor 304 controls the motor gear 305 to rotate, and drives the lower gear 309, the gear shaft 308 and the upper bevel gear 313 to rotate through the docking gear 306, thereby driving the side bevel gear 307, the rotating shaft 314 and the clamping plate 201 to rotate, thereby driving the metal raw material 4 to rotate, and the inner rotating ring 312 is clamped by the clamping block 310, so that when the toggle head 105 is not located in the toggle wheel 106, the relative position of the rotating seat 302 and the fixed seat 301 remains stable. The metal material 4 is clamped by the clamping mechanism of the self-rotating mechanism near the side of the vertical rod 112, and the metal material 4 is driven to rotate by the self-rotating mechanism. The periodic motor 103 controls the periodic lever 104 to rotate. When the toggle head 105 enters the groove of the toggle wheel 106, it will drive the toggle wheel 106, the top gear 303 and the rotating seat 302 to rotate ninety degrees. Due to the engagement of the two top gears 303, the rotation directions of the two rotating seats 302 are opposite. Then the toggle head 105 is disengaged from the toggle wheel 106, realizing the intermittent rotation of the rotating seat 302 and the top gear 303, and each time it rotates ninety degrees, each time the rotating seat 302 rotates once, the lifting electric cylinder 107 is extended and retracted once, and the extension of the lifting electric cylinder 107 drives the lifting frame 108 to rise , thereby driving the outer turning tool 109, the grinding tool 110 and the lifting triangle block 111 to rise, and at the same time driving the rotating rod 113 to rotate. When the metal raw material 4 is located above the outer turning tool 109, the outer turning tool 109 rises to cooperate with the self-rotation of the metal raw material 4 to cut the metal raw material 4 into a specified length. When the metal raw material 4 is located above the grinding tool 110, the grinding tool 110 rises to cooperate with the self-rotation of the metal raw material 4 to grind the cut surface of the metal raw material 4. When the metal raw material 4 is located in front of the inner turning tool 118, the rotating rod 113 rotates to drive the extension frame 114 and the extension column 115 to slide back and forth, so that the extension frame 114 moves to the farthest point toward the metal raw material 4 and then slides inward. The guide column 119 first enters the expansion section 1171 along the initial section 1175.At this time, the inner turning tool 118 cooperates with the self-rotation of the metal raw material 4 to perform preliminary cutting of the inner ring, and cooperates with the sliding of the left and right sliders 116 relative to the extension frame 114. Then the guide column 119 reaches the deep section 1172 along the expansion section 1171. At this time, the inner turning tool 118 expands the inner ring of the metal raw material 4, so that the inner ring cutting of the metal raw material 4 is completed. Then the guide column 119 reaches the farthest point along the reset section 1173, and then the guide column 119 returns to the initial position along the return section 1174 and the initial section 1175. When the metal raw material 4 reaches the top of the lifting triangle block 111 on the side of the vertical rod 112, the fixing seat 301 of the clamping mechanism on the rotation mechanism on the side of the motor frame 102 is just located in front of the metal raw material 4. At this time, the metal raw material 4 stops rotating. When the metal raw material 4 reaches the top of the lifting triangle block 111 on the side of the vertical rod 112, the clamping column 210 is located at the lower position on the clamping plate 201. The lifting triangle block 111 rises and contacts with the clamping column 210, thereby driving the clamping column 210 to slide along the lifting seat 209. , the clamping column spring 211 is compressed, and the clamping column 210 releases the clamping of the outer sliding clamping frame 208. At this time, the clamping spring 212 rebounds, driving the lower pressure plate 205 to rise, and driving the outer sliding clamping frame 208 to slide inward through the outward push connecting rod 207. At the same time, the clamping claw 202 is driven to open outward through the clamping connecting rod 206 to release the clamping of the metal raw material 4. At the same time, the top plate 203 pops outward under the rebound action of the clamping spring 212, and the metal raw material 4 is bounced to the clamping machine on the rotation mechanism on the side of the motor frame 102. On the top plate 203 of the structure, since the elastic force of the clamping spring 212 of the clamping mechanism on the self-rotating mechanism on the side of the vertical rod 112 is greater than the elastic force of the clamping spring 212 of the clamping mechanism on the self-rotating mechanism on the side of the motor frame 102, the metal raw material 4 will cause the top plate 203 to be squeezed inward, thereby driving the lower pressure plate 205 to slide inward, and the clamping mechanism on the self-rotating mechanism on the side of the motor frame 102 is clamped on the metal raw material 4 in the same way, thereby realizing the transfer of the metal raw material 4 between the two clamping mechanisms. Subsequently, the end face of the other end of the metal raw material 4 is cut and polished by the self-rotating mechanism on the side of the motor frame 102 in the same way. When the metal raw material 4 moves to the jacking triangle block 111 on the side of the motor frame 102, the jacking triangle block 111 rises to unlock the clamping mechanism, ejecting the processed metal raw material 4 to complete the processing.
