Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tower base assembly, and particularly relates to a tower base assembly device. BACKGROUND

[0002] The tower base of a bicycle is a core component of a rear wheel hub, and is usually located at the driving side of the hub. The tower base is generally composed of an inner ring and an outer shell. The inner ring includes a threaded ball cup and a middle piece. The outer shell is sleeved on the outer periphery of the inner ring. A ball set is arranged between the outer shell and the inner ring. The outer side of the outer shell is provided with a clamping groove for mounting a freewheel sheet. The outer shell and the inner ring are connected in transmission through a ratchet and pawl structure. Thus, the chain drives the outer shell to rotate through the freewheel sheet. The outer shell drives the inner ring to rotate through the ratchet and pawl structure. The inner ring transmits power to the hub body to drive the rear wheel to rotate. When the rear wheel rotates due to inertia, the inner ring of the tower base rotates with the rear wheel. At this time, the pawl inside the tower base slides on the ratchet. That is, the outer shell remains stationary, and the inner ring rotates freely relative to the outer shell.

[0003] From the above, in the production process of the tower base, the ball cup, the middle piece, the ball set and the outer shell are assembled together in advance to form a complete tower base. Specifically, the ball cup, the middle piece, the ball set and the outer shell are first pre-assembled together, and then the ball cup and the middle piece are tightened through a related module to obtain a complete tower base. However, in the prior art, the ball cup and the middle piece are over-tightened, which causes the ball set to be over-pressed against the outer shell by the inner ring. Thus, the outer shell and the inner ring of the tower base cannot rotate smoothly relative to each other due to the blocking problem between the ball set and the outer shell, which leads to the fact that the obtained tower base does not meet the quality standard, and thus the qualified rate of the obtained tower base is reduced.

[0057] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0058] Based on existing technologies, such as Figures 1 to 3 As shown, the bicycle hub includes an inner ring 11 and an outer shell 12. The inner ring 11 includes a bead cup 111 and a neutron 112. The bead cup 111 is screwed to one end of the neutron 112. The outer shell 12 is fitted around the outer periphery of the inner ring 11, and the end of the neutron 112 away from the bead cup 111 extends out of the outer shell 12. The end of the neutron 112 extending out of the outer shell 12 is used to connect to the hub body.

[0059] Furthermore, a ball set 13 is provided between the outer shell 12 and the inner ring 11. Specifically, two sets of ball sets 13 are arranged around the outer periphery of the inner ring 11, and the two sets of ball sets 13 are spaced apart along the axial direction of the inner ring 11. A first protrusion 121 is provided on the inner wall of the outer shell 12, and a second protrusion 1121 is provided on the outer periphery of the neutron 112. One set of ball sets 13 is stopped between the first protrusion 121 and the ball cup 111 along the axial direction of the inner ring 11, and the other set of ball sets 13 is stopped between the first protrusion 121 and the second protrusion 1121 along the axial direction of the inner ring 11.

[0060] Furthermore, it is worth noting that since the specific structure and working principle of the ratchet and pawl structure between the inner ring 11 and the outer shell 12 are existing technologies, this embodiment will not elaborate on them.

[0061] For instructions on assembling the tower base, please refer to the above. Figures 4 to 18 This embodiment provides a tower base assembly device, which includes a tightening mechanism 2 and a grinding mechanism 3. The tightening mechanism 2 is used to tighten the ball cup 111 and the neutron 112, and the grinding mechanism 3 is used to grind the side of the outer shell 12 that contacts the ball assembly 13.

[0062] Specifically, the tightening mechanism 2 includes a tightening head 21 and a first driving member 22. The tightening head 21 conforms to the shape of the bead cup 111 and docks with the bead cup 111. The first driving member 22 drives the tightening head 21 to rotate around its axis, thereby causing the bead cup 111 to rotate around its axis relative to the outer shell 12 and the neutron 112, thereby tightening the bead cup 111 and the neutron 112.

[0063] The grinding mechanism 3 includes a first grinding head 31 and a second driving member 32. The first grinding head 31 conforms to the outer shell 12 and docks with the outer shell 12. The second driving member 32 drives the first grinding head 31 to rotate around its axis, thereby causing the outer shell 12 to rotate around its axis, and thus grinding the side of the outer shell 12 that contacts the ball assembly 13.

[0064] Based on the structural design of the tower base, the end of the bead bowl 111 away from the middle 112 is provided with a slot 1111, and correspondingly, the end of the tightening head 21 is provided with an insertion block 211 in this embodiment. The tightening head 21 can be inserted into the shell 12, and the insertion block 211 can be inserted into the slot 1111, thereby being in abutment with the bead bowl 111. Then, the first driving member 22 drives the tightening head 21 to rotate around its axis, thereby driving the bead bowl 111 to rotate around its axis, and further tightening the bead bowl 111 and the middle 112.

[0065] In addition, the outer wall of the shell 12 is provided with a clamping groove 122 extending along the axial direction of the shell 12, and the inner wall of the first grinding head 31 is provided with a clamping block 311. The first grinding head 31 can be sleeved on the outer periphery of the shell 12, and the clamping block 311 can be clamped in the clamping groove 122, thereby being in abutment with the shell 12. Then, the second driving member 32 drives the first grinding head 31 to rotate around its axis, thereby driving the shell 12 to rotate relative to the inner ring 11.

[0066] It can be understood that the direction in which the first grinding head 31 drives the shell 12 to rotate is opposite to the direction in which the shell 12 rotates when the tower base works on the bicycle. Therefore, the first grinding head 31 can drive the shell 12 to rotate relative to the inner ring 11 without being affected by the ratchet and pawl structure therebetween.

[0067] Based on the foregoing, in this embodiment, the bead bowl 111, the middle 112, the ball set 13, and the shell 12 are first preassembled together, and then the preassembled tower base is transferred to the tightening mechanism 2. The tightening head 21 of the tightening mechanism 2 is inserted into the tower base from one end of the tower base and is in abutment with the bead bowl 111. Then, the first driving member 22 drives the tightening head 21 to rotate, thereby tightening the bead bowl 111 and the middle 112.

[0068] After the bead bowl 111 and the middle 112 are tightened, the tower base is transferred to the grinding mechanism 3. The first grinding head 31 of the grinding mechanism 3 is sleeved on the outer periphery of the shell 12 and is in abutment with the shell 12. Then, the second driving member 32 drives the first grinding head 31 to rotate, thereby driving the shell 12 to rotate relative to the inner ring 11. During the rotation, if the bead bowl 111 and the middle 112 are excessively tightened, the side of the shell 12 in contact with the ball set 13 will be gradually ground due to the friction between the shell 12 and the ball set 13, thereby preventing the subsequent ball set 13 from interfering with the relative rotation of the inner ring 11 and the shell 12.

[0069] From the above, the tightening mechanism 2 is used to tighten the bead bowl 111 and the middle 112, and the grinding mechanism 3 is used to eliminate the blocking problem between the ball set 13 and the shell 12, thereby ensuring that the shell 12 and the inner ring 11 of the prepared tower base can rotate smoothly relative to each other, and further ensuring that the prepared tower base meets the quality standards, thereby improving the yield of the prepared tower base.

[0070] In addition, in the embodiment, the tower base assembling device further comprises a conveying mechanism, which sequentially conveys the pre-assembled tower base to the tightening mechanism 2 and the grinding mechanism 3.

[0071] Specifically, the conveying mechanism comprises a rotating disc 61 and a rotating module 62, the rotating disc 61 carries the tower base, the tightening mechanism 2 and the grinding mechanism 3 are sequentially arranged along the circumference of the rotating disc 61, and the rotating module 62 drives the rotating disc 61 to rotate around its axis, so that the tower base can be sequentially rotated to the tightening mechanism 2 and the grinding mechanism 3, and then the tightening mechanism 2 and the grinding mechanism 3 can sequentially perform the tightening operation and the grinding operation on the pre-assembled tower base.

[0072] Therefore, the embodiment can continuously perform the tightening operation and the grinding operation on the tower base, and can realize the automatic transfer of the tower base, thereby improving the production efficiency of the tower base.

[0073] Based on the above, the conveying mechanism further comprises a carrier 611, which is arranged on the rotating disc 61 and is used to carry the tower base, that is, in the embodiment, the rotating disc 61 carries the tower base through the carrier 611, and as the rotating disc 61 rotates, the carrier 611 can be sequentially transferred to the tightening mechanism 2 and the grinding mechanism 3.

[0074] It can be understood that the carrier 611 is shaped like the end of the spindle 112 away from the bead bowl 111, that is, the carrier 611 is shaped like the end of the spindle 112 extending out of the shell 12, based on the structural design of the tower base, the carrier 611 can accommodate and fix the end of the spindle 112 extending out of the shell 12, and the end of the bead bowl 111 provided with the insertion slot 1111 faces upward and is exposed from the top of the shell 12, so that when the carrier 611 is transferred to the tightening mechanism 2, the tightening head 21 can be inserted into the tower base and docked with the bead bowl 111.

[0075] Correspondingly, when the carrier 611 is transferred to the grinding mechanism 3, the first grinding head 31 can be docked with the shell 12.

[0076] Specifically, based on the structural design of the tower base, the end of the spindle 112 away from the bead bowl 111 is provided with an insertion slot 1122, the slot wall of the insertion slot 1122 forms an inner spline 11221, and the tower base is drivingly connected with the hub body through the inner spline 11221. Correspondingly, the carrier 611 is provided with an accommodation slot 6111 for accommodating the end of the spindle 112 extending out of the shell 12, the accommodation slot 6111 is provided with a clamping column 6112, the outer periphery of the clamping column 6112 forms an outer spline 61121, the clamping column 6112 can be inserted into the accommodation slot 6111, and the inner spline 11221 and the outer spline 61121 are correspondingly clamped, so that the carrier 611 accommodates and fixes the end of the spindle 112 extending out of the shell 12.

[0077] When the carrier 611 is moved to the tightening mechanism 2, the tightening head 21 can be inserted into the tower base and be in butt joint with the ball bowl 111, and as the tightening head 21 rotates, the ball bowl 111 rotates around its axis at the same time, while the inner ball 112 is fixed by the carrier 611, thus the ball bowl 111 and the inner ball 112 are tightened.

[0078] Correspondingly, when the carrier 611 is moved to the grinding mechanism 3, the first grinding head 31 can be in butt joint with the outer shell 12, and as the first grinding head 31 rotates, the outer shell 12 rotates around its axis at the same time, while the inner ring 11 is fixed by the carrier 611, thus the side of the outer shell 12 in contact with the ball set 13 is ground.

[0079] In addition, it also needs to be explained that based on the above, the tightening head 21 and the first driving member 22 constitute a tightening module, and in addition to the tightening module, the tightening mechanism 2 also comprises a first lifting module 24, which is used to drive the tightening module to lift along the vertical direction, that is, the first lifting module 24 can drive the tightening head 21 and the first driving member 22 to lift along the vertical direction, thus when the carrier 611 is located at the tightening mechanism 2, the first lifting module 24 drives the tightening head 21 and the first driving member 22 to descend along the vertical direction, so that the tightening head 21 is in butt joint with the ball bowl 111, and then the subsequent tightening operation of the ball bowl 111 is carried out. When the tightening operation is completed, the first lifting module 24 drives the tightening head 21 and the first driving member 22 to ascend along the vertical direction, so that the tightening head 21 is separated from the ball bowl 111, and then the carrier 611 can drive the tower base to move to the grinding mechanism 3.

[0080] Correspondingly, the first grinding head 31 and the second driving member 32 constitute a grinding module, and in addition to the grinding module, the grinding mechanism 3 also comprises a second lifting module 34, which is used to drive the grinding module to lift along the vertical direction, that is, the second lifting module 34 can drive the first grinding head 31 and the second driving member 32 to lift along the vertical direction, thus when the carrier 611 is located at the grinding mechanism 3, the second lifting module 34 drives the first grinding head 31 and the second driving member 32 to descend along the vertical direction, so that the first grinding head 31 is in butt joint with the outer shell 12, and then the subsequent grinding operation of the outer shell 12 is carried out. When the grinding operation is completed, the second lifting module 34 drives the first grinding head 31 and the second driving member 32 to ascend along the vertical direction, so that the first grinding head 31 is separated from the outer shell 12.

[0081] It is worth mentioning that in the present embodiment, the first driving member 22 and the second driving member 32 can be selected as driving structures such as stepper motors or servo motors, and the present embodiment does not make specific limitations thereto.

[0082] It is worth mentioning that in the embodiment, the first lifting module 24 and the second lifting module 34 can be selected as a pneumatic cylinder, an electric cylinder or a KK module, and the embodiment does not make specific limitation.

[0083] Further, the tower base assembly device further comprises a first detection mechanism 4, the first detection mechanism 4 comprises a second grinding head 41, a third driving member 42 and a first torque sensor 43, wherein the second grinding head 41 is profiled with the shell 12 and is in abutment with the shell 12, the third driving member 42 drives the second grinding head 41 to rotate around its axis, thereby driving the shell 12 to rotate around its axis, and the first torque sensor 43 is arranged between the second grinding head 41 and the third driving member 42.

[0084] From the above, the embodiment detects the rotation smoothness of the shell 12 after the grinding operation through the first detection mechanism 4, thereby detecting whether the blocking problem between the ball set 13 and the shell 12 is effectively eliminated.

[0085] Specifically, based on the above-mentioned content, the first detection mechanism 4 is arranged on the downstream side of the grinding mechanism 3 along the circumference of the rotating disc 61, and the rotating module 62 drives the rotating disc 61 to rotate around its axis, thereby being able to rotate the tower base from the grinding mechanism 3 to the first detection mechanism 4, and further performing the smoothness detection operation on the tower base.

[0086] It is worth mentioning that, similarly to the first grinding head 31, the inner wall of the second grinding head 41 is also provided with a clamping block 311, the second grinding head 41 can be sleeved on the outer circumference of the shell 12, and the clamping block 311 can be clamped in the clamping groove 122, thereby being in abutment with the shell 12, then the third driving member 42 drives the second grinding head 41 to rotate around its axis, thereby being able to drive the shell 12 to rotate relative to the inner ring 11. Moreover, the direction in which the second grinding head 41 drives the shell 12 to rotate is opposite to the rotation direction of the shell 12 when the tower base works on the bicycle, thereby the second grinding head 41 can drive the shell 12 to rotate relative to the inner ring 11 without being affected by the ratchet and pawl structure between them.

[0087] When the outer ring rotates, the first torque sensor 43 can detect the torque of the second grinding head 41 driving the shell 12 to rotate, thereby detecting the rotation smoothness of the shell 12.

[0088] Further, the second grinding head 41 and the third driving member 42 constitute a smoothness detection module. In addition to the smoothness detection module, the first detection mechanism 4 further comprises a third lifting module 44, which is used to drive the smoothness detection module to ascend or descend along the vertical direction, i.e., the third lifting module 44 can drive the second grinding head 41 and the third driving member 42 to ascend or descend along the vertical direction. Thus, when the carrier 611 is located at the first detection mechanism 4, the third lifting module 44 drives the second grinding head 41 and the third driving member 42 to descend along the vertical direction, so that the second grinding head 41 is in abutment with the shell 12, and then the subsequent smoothness detection operation on the shell 12 is performed. When the smoothness detection operation is completed, the third lifting module 44 drives the second grinding head 41 and the third driving member 42 to ascend along the vertical direction, so that the second grinding head 41 is separated from the shell 12.

[0089] It is worth noting that in the present embodiment, the third driving member 42 can be a stepper motor or a servo motor or the like driving structure, and the present embodiment does not make specific limitation on this. The third lifting module 44 can be a pneumatic cylinder or an electric cylinder or a KK module or the like linear driving structure, and the present embodiment also does not make specific limitation on this.

[0090] Further, the second torque sensor 23 is arranged between the tightening head 21 and the first driving member 22, and the second torque sensor 23 can detect the torque of the tightening head 21 driving the rotation of the ball bowl 111, so as to ensure that the ball bowl 111 is effectively tightened to the middle part 112.

[0091] Further, the tower base assembly device further comprises a second detection mechanism 5, which comprises a positioning table 51, a first pushing module 52 and a second pushing module 53. The second detection mechanism 5 is used to perform a second detection on the tower base after the first detection mechanism 4 completes the detection. The second detection is to detect the gap between the shell 12 and the ball set 13, so as to detect whether the gap value between the shell 12 and the ball set 13 after grinding meets the requirements, and further ensure that the tower base to be shipped conforms to the quality standard.

[0092] The inner ring 11 is loaded and positioned on the positioning table 51. The first pushing module 52 comprises a pushing plate 521 and a mounting plate 522. The pushing plate 521 is slidingly connected to the mounting plate 522 and abuts against one side of the shell 12 along the radial direction. A displacement sensor 523 is arranged between the pushing plate 521 and the mounting plate 522. The second pushing module 53 comprises a pushing plate 531 and a fourth driving member 532. The fourth driving member 532 drives the pushing plate 531 to abut against the other side of the shell 12 along the radial direction. A pressure sensor 533 is arranged between the pushing plate 531 and the fourth driving member 532.

[0093] Therefore, the fourth driving member 532 drives the push plate 531 to push the shell 12 according to the preset pressure value. Since the abutting plate 521 abuts against the other side of the shell 12, and the abutting plate 521 is slidingly connected to the mounting plate 522, the abutting plate 521 can be pushed together with the shell 12. Meanwhile, the displacement sensor 523 detects the displacement value of the abutting plate 521 relative to the mounting plate 522, so as to obtain the displacement value of the shell 12 after being pushed, and further obtain the gap value between the shell 12 and the ball set 13, thereby completing the detection of the gap between the shell 12 and the ball set 13.

[0094] It is worth noting that the second detection mechanism 5 further comprises a base 55, and the positioning table 51, the first pushing module 52 and the second pushing module 53 are all mounted on the base 55. The first pushing module 52 and the second pushing module 53 are oppositely arranged, and the positioning table 51 is arranged between the first pushing module 52 and the second pushing module 53.

[0095] The first pushing module further comprises a fifth driving member 524 mounted on the base 55, and the fifth driving member 524 is used to drive the mounting plate 522 and the abutting plate 521 to move towards the second pushing module 53, so that the abutting plate 521 abuts against the shell 12.

[0096] In addition, the push plate 531 is slidingly connected to the base 55, and the fourth driving member 532 drives the push plate 531 to move towards the first pushing module 52, so as to push the shell 12 of the tower.

[0101] Moreover, the positioning plate 512 and the carrier block 511 are provided with a reset spring 514, when the positioning plate 512 moves towards the side close to the accommodating groove 5111, the reset spring 514 is elastically deformed, thereby being capable of driving the positioning plate 512 to reset after the transmission plate 5132 resets, thereby releasing the clamping of the tower base, and then being capable of taking the tower base off the carrier block 511 subsequently.

[0102] In addition, the top of the sliding groove 5112 is provided with a baffle 5113, thereby limiting the moving direction of the positioning plate 512.

[0103] It can be understood that the sixth driving member 5131 can be selected as a gas cylinder or an electric cylinder or a KK module or other linear driving structure, and the embodiment does not make specific limitation thereto.

[0104] In addition, it is worth mentioning that, in the embodiment, the second detection mechanism 5 is arranged on the downstream side of the first detection mechanism 4 along the circumferential direction of the rotating disc 61, the rotating module 62 drives the rotating disc 61 to rotate around its axis, thereby being capable of rotating the tower base from the first detection mechanism 4 to the second detection mechanism 5, and then performing the gap detection operation on the tower base.

[0105] Accordingly, the second detection mechanism 5 further comprises a carrying module 54, the carrying module 54 carries the tower base from the rotating disc 611 to the positioning table 51, specifically, the carrying module 54 carries the tower base from the carrier table 611 to the carrier block 511, thereby performing the gap detection operation on the tower base.

[0106] Exemplarily, in the embodiment, the carrying module 54 comprises a clamping jaw 541, a horizontal moving module 542 and a vertical moving module 543, wherein the clamping jaw 541 is used for clamping the tower base, the horizontal moving module 542 is used for driving the clamping jaw 541 to move in the horizontal direction, and the vertical moving module 543 is used for driving the clamping jaw 541 to move in the vertical direction, thereby enabling the clamping jaw 541 to take the tower base off the carrier table 611 and put it into the carrier block 511.

[0107] The clamping jaw 541 can be a pneumatic clamp or an electric clamp, and the specific structure and working principle of the clamping jaw 541 are known in the art, and thus will not be described herein.

[0108] The horizontal transfer module 542 and the vertical transfer module 543 can be a pneumatic cylinder, an electric cylinder or a KK module, and the specific structure and working principle of the horizontal transfer module 542 and the vertical transfer module 543 are known in the art, and thus will not be described herein.

[0109] In addition, the tower base assembly device further comprises a defective product discharge channel 71 and a good product discharge channel 72, and the transfer module 54 further transfers the tower base from the turntable 61 to the defective product discharge channel 71, i.e., if the blocking problem between the ball set 13 and the outer shell 12 is not effectively eliminated by the first detection mechanism 4, the transfer module 54 directly transfers the tower base to the defective product discharge channel 71 when the turntable 611 is moved to the second detection mechanism 5, and if the blocking problem between the ball set 13 and the outer shell 12 is effectively eliminated by the first detection mechanism 4, the transfer module 54 transfers the tower base to the positioning table 51 when the turntable 611 is moved to the second detection mechanism 5.

[0110] In addition, the transfer module 54 can further transfer the tower base from the positioning table 51 to the defective product discharge channel 71 or the good product discharge channel 72, and specifically, if the gap value between the outer shell 12 and the ball set 13 meets the requirements, the transfer module 54 transfers the tower base from the positioning table 51 to the good product discharge channel 72, and if the gap value between the outer shell 12 and the ball set 13 does not meet the requirements, the transfer module 54 transfers the tower base from the positioning table 51 to the defective product discharge channel 71.

[0111] Therefore, the tower base can be sorted, and the quality of the tower base can be further ensured.

[0112] In addition, it should be noted that the second detection mechanism 5 is provided with a photoelectric sensor 8, and the photoelectric sensor 8 is used to detect whether the transfer module 54 takes away the tower base on the turntable 611, so as to ensure that the second detection mechanism 5 can effectively detect.

[0113] Further, based on the foregoing, in the present embodiment, the tower base assembly device further comprises a turntable 61 and a rotating module 62, wherein the turntable 61 carries the tower base through the turntable 611, the tightening mechanism 2, the grinding mechanism 3, the first detection mechanism 4 and the second detection mechanism 5 are arranged along the circumference of the turntable 61 in sequence, and the rotating module 62 drives the turntable 61 to rotate around its axis, so as to sequentially transfer the tower base to the tightening mechanism 2, the grinding mechanism 3, the first detection mechanism 4 and the second detection mechanism 5.

[0114] Specifically, the rotating disc 61 is sequentially provided with a tightening station, a grinding station, a first detection station and a second detection station along the circumference thereof, the tightening mechanism 2, the grinding mechanism 3, the first detection mechanism 4 and the second detection mechanism 5 are respectively arranged at the tightening station, the grinding station, the first detection station and the second detection station, and the rotating disc 61 can sequentially transport the tower base to the tightening station, the grinding station, the first detection station and the second detection station, so as to sequentially perform the tightening operation, the grinding operation, the smoothness detection operation and the gap detection operation on the tower base.

[0115] Exemplarily, in the present embodiment, the rotating module 62 is a disc divider, of course, in other optional embodiments, the rotating module 62 can also be other rotating driving structures, and the present embodiment does not make specific limitation thereto.

[0116] It is worth noting that a plurality of rollers 63 are supported below the rotating disc 61, and the plurality of rollers 63 are uniformly arranged along the circumference of the rotating disc 61, so as to ensure that the rotating disc 61 can stably rotate along the circumference thereof.

[0117] From the above, in the present embodiment, the rotating disc 61 is uniformly arranged with six carriers 611 along the circumference thereof, and after the rotating disc 61 rotates once, the continuous four carriers 611 among all the carriers 611 are respectively located at the tightening mechanism 2, the grinding mechanism 3, the first detection mechanism 4 and the second detection mechanism 5.

[0118] Therefore, the upstream side of the tightening station is provided with a feeding station, and after the rotating disc 61 rotates once, the feeding station, the tightening station, the grinding station, the first detection station and the second detection station all correspondingly move in one carrier 611, wherein the carrier 611 moved into the feeding station is empty, and the worker can supplement a preloaded tower base to the carrier 611 located at the feeding station.

[0119] Based on the above, the present embodiment can shorten the production cycle of the tower base, so as to improve the production efficiency of the tower base.

[0120] It is worth noting that since the number of carriers 611 is greater than the number of stations arranged on the outer periphery of the rotating disc 61, the tower base assembly equipment can also arrange other stations on the outer periphery of the rotating disc 61.

[0121] It is also worth noting that for the carrier 611 moved out of the second detection station, the carrier 611 will first move to between the second detection station and the feeding station, and will move to the feeding station after the rotating disc 61 rotates next time.

[0122] It can be understood that five or more than seven loading platforms 611 can be arranged uniformly on the rotating disc 61 in other optional embodiments, and the loading station, the tightening station, the grinding station, the first detection station and the second detection station correspondingly move in one loading platform 611 after one rotation of the rotating disc 61, and the embodiment does not make specific limitation on this.

[0124] It can be understood that even if the third torque sensor 33 can detect the torque of the first grinding head 31 driving the rotation of the shell 12 in real time, based on the production requirements, the rotation smoothness of the shell 12 after the grinding operation is still needed to be detected after the grinding is completed, and the embodiment divides the grinding operation and the smoothness detection operation into two stations, so that the next tower base can be immediately moved to the grinding station for grinding operation after completing the tightening operation, thereby shortening the production rhythm of the tower base.
