Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Please see Figures 1-8 The automatic positioning and rotating mechanism shown in the figure includes a fixed base 101, on which a mounting platform 103 is fixed via a connecting bracket 102, and further includes:

[0031] A positioning and clamping assembly is mounted on the mounting platform 103 for positioning and clamping irregular cylindrical objects. The positioning and clamping assembly is provided with an elastic component for elastically pushing the positioning and clamping assembly and a drive component for driving the positioning and clamping assembly.

[0032] A rotating component is mounted on a fixed base 101 and is used to drive the positioning clamping component to rotate. A transmission component for auxiliary connection transmission is provided between the rotating drive component and the positioning clamping component.

[0033] The positioning and clamping assembly includes a rotary table 201 rotatably connected to the mounting platform 103. The upper end of the rotary table 201 is provided with a positioning groove 202 for positioning against the end of the irregular column. The interior of the rotary table 201 is provided with a mounting cavity. Two sets of sliding grooves 203 are symmetrically provided between the mounting cavity and the positioning groove 202. The sliding grooves 203 communicate with the positioning grooves 202. A clamping plate 204 for fixing against the outside of the irregular column is slidably connected to the sliding grooves 203.

[0034] It should be noted that the positioning and clamping components, elastic components, driving components, and rotating components work together to achieve rapid positioning and clamping of irregularly shaped cylinders. With the assistance of the driving components, the positioning, clamping, and rotating of irregularly shaped cylinders can be achieved.

[0035] Preferably, the elastic component includes two sets of mounting racks 301 disposed inside the mounting cavity, two sets of clamping plates 204 respectively fixed on the two sets of mounting racks 301, a first guide component for guiding and connecting the mounting racks 301 is disposed inside the mounting cavity, mounting holes are provided on the mounting racks 301, mounting rods 302 are slidably connected to the mounting holes, a fixing plate 303 is fixed to one end of the mounting rod 302, the fixing plate 303 is fixed inside the mounting cavity, a push spring 304 is sleeved on the outside of the mounting rod 302, and the two ends of the push spring 304 are respectively abutted against the fixing plate 303 and the mounting racks 301;

[0036] It should be noted here that the mounting rod 302 and the mounting hole guide the movement of the mounting rack 301 after being subjected to force, and the spring 304 is pushed to facilitate the elastic push of the mounting rack 301.

[0037] Preferably, the drive assembly includes two sets of first mounting shafts 501 symmetrically arranged and rotatably connected inside the mounting cavity. Gears 502 are fixed on the first mounting shafts 501. The two sets of gears 502 are respectively meshed with two sets of mounting racks 301. A push plate 503 is slidably connected on the rotary table 201. One end of the push plate 503 is located inside the mounting cavity and is fixed with a double-sided rack 504. The double-sided rack 504 is located between the two sets of gears 502 and meshes with each other. A second guide assembly for assisting the guide connection of the double-sided rack 504 is provided inside the mounting cavity.

[0038] It should be noted here that: First, push the push plate 503 toward the rotary table 201. During the pushing process, the double-sided rack 504 moves inside the mounting cavity. During the movement, through the sliding guidance of the two sets of second guide pins 602 and the guide grooves 601 on the double-sided rack 504, the double-sided rack 504 moves between the two sets of gears 502 after being subjected to force. During the movement, through the mutual meshing transmission between the double-sided rack 504 and the two sets of gears 502, the two sets of gears 502 and the first mounting shaft 501 rotate. During the rotation of the two sets of gears 502, through the mutual meshing transmission between the two sets of gears 502 and the two sets of mounting racks 301, the two sets of mounting racks 301 are subjected to force and move.

[0039] Preferably, the first guide assembly includes a guide frame 401 fixed inside the mounting cavity, and two sets of first guide pins 402 fixed on the mounting rack 301, the first guide pins 402 being slidably connected to the guide frame 401;

[0040] It should be noted here that the movement of the rack 301 after being subjected to force is guided by the guide frame 401 and the two sets of first guide pins 402.

[0041] Preferably, the second guide assembly includes a guide groove 601 centrally located on the double-sided rack 504, and two sets of second guide pins 602 are slidably connected inside the guide groove 601, with the second guide pins 602 fixed inside the mounting cavity.

[0042] It should be noted here that the interaction between the guide groove 601 and the two sets of second guide pins 602 guides the movement of the double-sided rack 504 after being subjected to force.

[0043] Preferably, the rotating assembly includes a slide 701 disposed on one side of the fixed base 101. A sliding component for assisting sliding and a recognition component for recognizing the sliding state are disposed between the slide 701 and the fixed base 101. A cylinder 706 for driving the slide 701 to lift and lower is disposed on the fixed base 101. A side platform 702 is fixed on the slide 701. A second mounting shaft 703 is rotatably connected to the side platform 702. A motor 704 is mounted on the slide 701. The output end of the motor 704 is connected and fixed to the second mounting shaft 703 through a connecting sleeve 705. The transmission assembly includes a connecting plate 801 fixed to the lower end of the rotating table 201. A plurality of connecting holes 802 are provided on the connecting plate 801. One end of the second mounting shaft 703 is connected to the mounting plate 803 through a telescopic component. A pin 804 for inserting and connecting with the connecting holes 802 is fixed to the upper end of the mounting plate 803.

[0044] It should be noted that after the irregularly shaped column is positioned and clamped, the cylinder 706 pushes the slide 701 upward. During this pushing process, the slide rail 1001 and the sliding plate 1002 guide the slide 701 under force, causing it to move upward on one side of the fixed base 101. This movement drives the mounting plate 803 to rise synchronously. During the upward movement of the mounting plate 803, when the pins 804 on the mounting plate 803 are aligned with the connecting holes 802 on the connecting plate 801, the rising of the mounting plate 803 causes each set of pins 804 to directly insert into its respective connecting hole 802, completing the connection between the mounting plate 803 and the connecting plate 801. When the pins 804 on the mounting plate 803 are not aligned with the connecting holes 802 on the connecting plate 801, the pins 804 abut against the bottom of the connecting plate 801. During this abutment, the mounting plate 803... The movement continues, causing relative axial movement between the mounting plate 803 and the second mounting shaft 703. During this movement, the spline shaft 902 slides on the spline cylinder 901, and the mounting spring 903 is compressed and deformed to generate elastic force. At this time, the connecting plate 801 is rotated. During the rotation, the connecting holes 802 on the connecting plate 801 are aligned with the pins 804. Through the elastic force of the mounting spring 903, the pins 804 are pushed into the interior of the connecting holes 802, thus completing the connection between the mounting plate 803 and the connecting plate 801. After the mounting plate 803 and the connecting plate 801 are connected, the second mounting shaft 703 is driven to rotate by the driving action of the motor 704 and the connecting action of the connecting sleeve 705. During the rotation of the second mounting shaft 703, the rotary table 201 is driven to rotate by the connection transmission between the spline cylinder 901 and the spline shaft 902 and the connection transmission between the mounting plate 803 and the connecting plate 801.

[0045] Preferably, the telescopic assembly includes a splined cylinder 901 fixed to one end of the second mounting shaft 703, a splined shaft 902 slidably connected to the splined cylinder 901, one end of the splined shaft 902 being fixed to the mounting plate 803, and a mounting spring 903 sleeved on the outer side of the splined cylinder 901. The two ends of the mounting spring 903 are respectively connected to the mounting plate 803 and the second mounting shaft 703. The rotary table 201, the connecting plate 801, the mounting plate 803, the second mounting shaft 703, the splined cylinder 901, and the splined shaft 902 are concentrically arranged.

[0046] It should be noted that: the splined cylinder 901 and the splined shaft 902 facilitate the telescopic connection between the auxiliary mounting plate 803 and the second mounting shaft 703; the installation spring 903 facilitates the reset after the telescopic movement; in addition, during the rotation of the second mounting shaft 703, the splined cylinder 901 and the splined shaft 902 can drive the mounting plate 803 to rotate synchronously.

[0047] Preferably, the sliding assembly includes a slide rail 1001 fixed to one side of the fixed base 101, a slide plate 1002 slidably connected to the slide rail 1001, and the slide plate 1002 fixed to one side of the slide table 701;

[0048] It should be noted here that the slide rail 1001 and the slide plate 1002 facilitate the sliding connection of the slide table 701.

[0049] Preferably, the identification component includes an identification block 1101 fixed to one side of the slide table 701, two sets of L-shaped frames 1102 fixed on the fixed base 101, the identification block 1101 located between the two sets of L-shaped frames 1102, and a proximity sensor 1103 for identification when the identification block 1101 approaches is installed on the L-shaped frame 1102.

[0050] It should be noted that during the movement of the slide table 701, the recognition block 1101 moves synchronously. During the movement of the recognition block 1101, the position of the recognition block 1101 is identified by two sets of proximity sensors 1103, which further facilitates a more intuitive judgment of the moving position of the slide table 701.

[0051] In addition, the identification block 1101 and the proximity sensor 1103 are conventional components for distance identification and judgment in the technical field of this application, and their working principle and control method will not be described in detail here.

[0052] In this solution: an automatic positioning and rotating mechanism includes the following steps:

[0053] During the clamping and rotating operation of the irregularly shaped column, the push plate 503 is first pushed towards the rotary table 201. During this pushing process, the double-sided rack 504 moves inside the mounting cavity. During this movement, the double-sided rack 504, under stress, moves between the two sets of gears 502 through the sliding guidance of the guide grooves 601 on the double-sided rack 504 via the two sets of second guide pins 602. During this movement, the double-sided rack 504 meshes with the two sets of gears 502, causing the two sets of gears 502 and the first mounting shaft 501 to rotate. During the rotation of the two sets of gears 502, the two sets of gears mesh with the two sets of mounting racks 301, causing the two sets of mounting racks 301 to move under stress. During the movement of the mounting racks 301, the two sets of first guide pins 402 and the guide frame 401 provide sliding guidance for the stressed mounting racks 301, ensuring smooth movement. 301 moves away from each other and continuously compresses the push spring 304, increasing the elastic force of the push spring 304. During the movement of the two sets of mounting racks 301, the two sets of clamping plates 204 move synchronously, causing one end of the two sets of clamping plates 204 to slide out of the positioning groove 202, completing the retraction drive of the two sets of clamping plates 204. After the retraction drive of the two sets of clamping plates 204 is completed, because the positioning groove 202 on the rotary table 201 is set to match the end shape of the irregular column, the positioning groove 202 positions one end of the irregular column on the rotary table 201. After placement, the two sets of clamping plates 204 are no longer retracted and pulled. At this time, the elastic force of the push spring 304 causes the two sets of clamping plates 204 to reset. During the reset process, one end of the two sets of clamping plates 204 abuts against the outside of the positioned irregular column. Through the abutment and compression action, the positioned irregular column is clamped and fixed.

[0054] After positioning and clamping the irregularly shaped column, the cylinder 706 pushes the slide 701 upward. During this pushing process, the slide rail 1001 and the sliding plate 1002 guide the slide 701 under force, causing it to move upward on one side of the fixed base 101. This movement drives the mounting plate 803 to rise synchronously. As the mounting plate 803 rises, when the pins 804 on the mounting plate 803 align with the connecting holes 802 on the connecting plate 801, the rising of the mounting plate 803 allows each set of pins 804 to directly insert into its respective connecting hole 802, completing the connection between the mounting plate 803 and the connecting plate 801. When the pins 804 on the mounting plate 803 align with the connecting holes 802, the rising of the mounting plate 803 allows each set of pins 804 to directly insert into its respective connecting hole 802, completing the connection between the mounting plate 803 and the connecting plate 801. When the pin 804 is not aligned with the connecting hole 802 on the connecting plate 801, the pin 804 abuts against the bottom of the connecting plate 801. During the abutment process, as the mounting plate 803 continues to move, the mounting plate 803 and the second mounting shaft 703 generate relative axial movement. During the movement, the spline shaft 902 slides on the spline cylinder 901 and the mounting spring 903 is compressed and deformed to generate elastic force. At this time, the connecting plate 801 is rotated. During the rotation, the connecting holes 802 on the connecting plate 801 are aligned with the pin 804. Through the elastic force of the mounting spring 903, the pin 804 is pushed into the interior of the connecting hole 802, thus completing the connection between the mounting plate 803 and the connecting plate 801.

[0055] After the mounting plate 803 and the connecting plate 801 are connected, the second mounting shaft 703 is driven to rotate by the driving action of the motor 704 and the connecting sleeve 705. During the rotation of the second mounting shaft 703, the rotary table 201 is driven to rotate by the connection transmission between the spline cylinder 901 and the spline shaft 902 and the connection transmission between the mounting plate 803 and the connecting plate 801. The rotation of the rotary table 201 realizes the positioning, clamping and rotation of the irregular column.
