[0002] In the related art, when assembling a water pump, it is necessary to assemble a mandrel and an impeller together; in order to improve the assembly efficiency of the water pump and avoid manual handling of the mandrel and the impeller, the impeller is usually sleeved outside the mandrel by a special assembly device.

[0003] The prior art (Chinese utility model patent, authorization publication number: CN205798845U) provides a water pump impeller assembly tooling, which solves the problems of low assembly efficiency and poor stability existing in the existing manual operation of water pump impeller assembly. It includes a frame and a workbench for placing the water pump. On the frame, there is a first manipulator for grasping a flat key and a second manipulator for grasping the impeller. The frame has a horizontally arranged outer plate. On the outer plate, there is a driving wheel driven by a motor for driving the water pump rotating shaft to rotate circumferentially along its central axis. The axis of the driving wheel is vertically arranged. On the outer plate, there is also a first driving unit for driving the driving wheel to move horizontally and a second driving unit for driving the driving wheel to move up and down.

[0018] A water pump assembly device of the present invention has the following beneficial effects compared with the prior art:

[0019] 1. By embedding the lifting and positioning mechanism into the first key groove and embedding the positioning mechanism into the second key groove, the positioning of the mandrel and the impeller is realized to determine the relative position between the mandrel and the impeller. Thus, when the impeller is sleeved outside the mandrel, it is ensured that the first key groove can be opposite to the second key groove, and further ensured that the connecting key can be simultaneously embedded into the first key groove and the second key groove, so as to improve the assembly accuracy of the mandrel and the impeller. When the impeller is sleeved outside the mandrel, there is no need to rotate the impeller to adjust the position of the second key groove, thereby improving the assembly efficiency and accuracy of the product, and at the same time avoiding interference between the connecting key and the impeller, so as to improve the quality of the product.

[0020] 2. By providing the first threaded hole in the translation plate and enabling the first lead screw to pass through the first threaded hole, the threaded connection between the first lead screw and the translation plate is realized, so as to realize the rotation of the first lead screw to drive the translation plate to move, and further adjust the position of the translation plate; by fixing the first motor on the workbench and connecting the first output shaft of the first motor to the first lead screw, it is realized that the first motor can drive the first lead screw to rotate, thereby providing power for rotating the first lead screw.

[0021] 3. When the mandrel is not embedded between the two first clamping blocks, start the first cylinder to drive the adjusting block to move away from the mandrel, so that the adjusting block presses the two first clamping blocks to move to both sides. Then, the first clamping blocks drive the first limiting plate to move outward through the first connecting rod. At this time, the first spring is in a stretched state. When the mandrel is embedded between the two first clamping blocks and is in contact with the two first clamping blocks at the same time, start the first cylinder to drive the adjusting block to move towards the mandrel. At this time, the first spring resets and drives the first connecting rod to move inward, so that the mandrel is embedded in the two first clamping grooves at the same time. Then, use the elastic force of the first spring to clamp the mandrel with the two first clamping blocks. After that, rotate the first slewing bearing to drive the first mounting bracket and the mandrel to rotate, so as to adjust the orientation of the first keyway, and then ensure that the first keyway faces upward, so as to facilitate the subsequent impeller to be sleeved on the outside of the mandrel.

[0022] 4. By arranging the first mounting groove in the translation plate and installing the second motor in the first mounting groove, the second motor can be hidden in the translation plate, and at the same time, the translation plate can support the second motor. By arranging the first external teeth on the outer wall of the first slewing bearing, sleeving the first gear on the outside of the second output shaft of the second motor, and meshing the first gear with the first external teeth, the second motor can drive the first gear to rotate, so that the first gear meshes with the first external teeth and drives the first slewing bearing to rotate, thereby providing power for rotating the mandrel.

[0023] 5. After the first clamping and rotating mechanism clamps the mandrel, start the second cylinder to drive the first lifting plate and the first positioning plate to move upward, and make the first positioning plate fit against the outer wall of the mandrel (the first positioning plate is not embedded in the first keyway). At this time, the second spring is compressed. Then, start the first clamping and rotating mechanism to drive the mandrel to rotate. When the first keyway is opposite to the first positioning plate, the second spring resets and drives the first positioning plate to be embedded in the first keyway, so that the mandrel stops rotating. At this time, the first clamping and rotating mechanism stops. After that, start the second cylinder to drive the first lifting plate and the first positioning plate to move downward, so that the first positioning plate disengages from the first keyway and drives the first lifting plate and the first positioning plate to be embedded in the first receiving groove to avoid interference between the first positioning plate and other components in the future. After that, start the first clamping and rotating mechanism to drive the mandrel to rotate 90 degrees, so that the first keyway faces upward, so as to facilitate the staff to place the connecting key in the first keyway.

[0024] 6. By installing the fourth cylinder on the second lifting plate and connecting the pressing plate to the fourth drive shaft of the fourth cylinder, the second lifting plate and the fourth cylinder can move up and down synchronously, so that the fourth cylinder can drive the pressing plate to move, and further the pressing plate can press the impeller on the outer side of the mandrel; by arranging the relief groove in the pressing plate and making the relief groove opposite to the mandrel, interference between the mandrel and the pressing plate can be avoided, so as to ensure that the pressing plate can press the impeller onto the outer side of the mandrel, thereby improving the user experience of the product.

[0025] 7. When the impeller is placed on the rotating plate from top to bottom, the impeller presses multiple second clamping blocks to move outward through the chamfer. At this time, the second clamping blocks compress the third spring, so that the elastic force of the third spring is used to clamp the impeller, ensuring that the rotating plate and the impeller rotate synchronously; then, the third motor is started, and the third motor drives the second gear to rotate, thereby driving the rotating plate and the impeller to rotate to adjust the position of the second keyway.

[0026] 8. When the impeller is placed on the rotating plate, the second positioning plate fits against the inner wall of the impeller (the second positioning plate is not embedded in the second keyway). At this time, the impeller presses the second positioning plate to move towards the midline direction of the impeller, so that the fourth spring is in a compressed state; then, the rotating plate and the impeller are rotated; when the second positioning plate is opposite to the second keyway, the fourth spring resets and drives the second positioning plate to move, so that the second positioning plate is embedded in the second keyway to achieve positioning of the second keyway.

[0027] 9. By arranging the second threaded hole in the translation stage and passing the second lead screw through the second threaded hole, the second lead screw is threadedly connected to the translation stage, so that rotating the second lead screw can drive the translation stage to move. By connecting the buffer seat to a second support plate, making the buffer seat located above the mandrel and opposite to the translation stage, a second support plate can support the buffer seat, so that when the translation stage moves to this second support plate, the translation stage contacts the buffer seat, and further positioning of the translation stage is achieved.

[0028] 10. Place the third lifting plate inside the lifting frame and pass the third lead screw through the third threaded hole of the third lifting plate to achieve threaded connection between the third lead screw and the third lifting plate, so as to rotate the third lead screw and drive the third lifting plate to move up and down inside the lifting frame; connect one end of two fifth connecting rods to the third lifting plate, pass the other ends of the two fifth connecting rods through the lifting frame, and connect the other ends of the two fifth connecting rods to the clamping and flipping mechanism, so that when the third lifting plate moves up and down, the third lifting plate drives the clamping and flipping mechanism to move up and down through the two fifth connecting rods, thereby adjusting the height of the clamping and flipping mechanism. Install the fifth motor on the translation table and sleeved the first pulley on the outside of the fifth output shaft of the fifth motor to support the fifth motor by the translation table, so as to enable the fifth motor to drive the first pulley to rotate; sleeve the second pulley on the outside of the rotating shaft and simultaneously sleeve the belt on the outside of the first pulley and the second pulley, so that when the fifth motor drives the first pulley to rotate, the first pulley drives the rotating shaft to rotate through the second pulley and the belt, thereby providing power for rotating the rotating shaft.

[0029] 11. When the second mounting bracket moves above the impeller and the first inner support block and the second inner support block are embedded in the impeller, start the sixth motor to drive the fourth lead screw to rotate, so that the fourth lead screw drives the first inner support block and the second inner support block to move in opposite directions, and then the first inner support block and the second inner support block are simultaneously in contact with the inner wall of the impeller; then, start the fifth motor to drive the third lead screw to rotate, so that the third lead screw drives the third lifting plate and the two fifth connecting rods to move upward, and then drives the second mounting bracket and the impeller to move upward; when the impeller moves upward to a predetermined height, start the fifth cylinder to drive the third mounting bracket to rotate 90 degrees, so that the impeller flips 90 degrees. At this time, the second key groove in the impeller is opposite to the connecting key placed in the first key groove; then, start the fourth motor to drive the second lead screw to rotate, so that the second lead screw drives the translation table and the impeller to move toward the mandrel direction, and then the impeller is sleeved on the outside of the mandrel; when at least two-thirds of the impeller is sleeved on the outside of the mandrel (at this time the mandrel can support the impeller), start the sixth motor to drive the fourth lead screw to rotate, so that the fourth lead screw drives the first inner support block and the second inner support block to move relatively, and then the first inner support block and the second inner support block are separated from the inner wall of the impeller; then, start the fourth motor to drive the second lead screw to rotate in the reverse direction, so that the second lead screw drives the translation table and the impeller to move away from the mandrel direction, and then the first inner support block and the second inner support block are removed from the impeller.

By installing the second clamping and rotating mechanism 23 on the workbench 13 and connecting the impeller 10 to the second clamping and rotating mechanism 23, the second clamping and rotating mechanism 23 can clamp the impeller 10 and drive the impeller 10 to rotate to adjust the position of the second keyway 12; by installing the positioning mechanism 25 on the workbench 13 and making the positioning mechanism 25 inserted into the second keyway 12, the workbench 13 can support the positioning mechanism 25, so that the positioning mechanism 25 can position the second keyway 12 and the impeller 10.By installing the second translation mechanism 26 on the top of the support frame 14 and connecting the translation table 27 to the second translation mechanism 26, it is realized that the second translation mechanism 26 can drive the translation table 27 to move, thereby adjusting the relative position between the translation table 27 and the mandrel 9; by installing the lifting mechanism 28 at the bottom of the translation table 27 and enabling the lifting mechanism 28 to pass through the support frame 14, it is realized that the translation table 27 can drive the lifting mechanism 28 to move, thereby adjusting the relative position between the lifting mechanism 28 and the mandrel 9; by connecting the clamping and flipping mechanism 30 to the lifting mechanism 28 and making the clamping and flipping mechanism 30 located above the impeller 10, it is realized that the lifting mechanism 28 can move the clamping and flipping mechanism 30 up and down, thereby enabling the clamping and flipping mechanism 30 to clamp the impeller 10 and drive the impeller 10 to flip, and further enabling the impeller 10 to be opposite to the mandrel 9, so as to facilitate sleeving the impeller 10 outside the mandrel 9.

[0050] When specifically using the product, first place the mandrel 9 in the support groove 16 of the support base 15 through a handling device (forklift), and place the impeller 10 on the second clamping and rotating mechanism 23; then, start the first translation mechanism 17 to drive the first clamping and rotating mechanism 19 to move by the first translation mechanism 17, so that the mandrel 9 is inserted into the first clamping and rotating mechanism 19; afterwards, start the first clamping and rotating mechanism 19, and the first clamping and rotating mechanism 19 clamps the mandrel 9; afterwards, start the lifting and positioning mechanism 21 to raise the lifting and positioning mechanism 21 and make the lifting and positioning mechanism 21 fit against the outer wall of the mandrel 9 (at this time, the lifting and positioning mechanism 21 is not inserted into the first keyway 11); afterwards, start the first clamping and rotating mechanism 19 to drive the mandrel 9 to rotate; when the lifting and positioning mechanism 21 is opposite to the first keyway 11, the lifting and positioning mechanism 21 is inserted into the first keyway 11, and at this time the first detection faces downward; afterwards, start the lifting and positioning mechanism 21 to lower the lifting and positioning mechanism 21, so that the lifting and positioning mechanism 21 disengages from the first keyway 11; afterwards, start the first clamping and rotating mechanism 19 to drive the mandrel 9 to rotate 90 degrees, so that the first keyway 11 faces upward; afterwards, place the connecting key in the first keyway 11; when the impeller 10 is placed on the second clamping and rotating mechanism 23, start the second clamping and rotating mechanism 23 to clamp the impeller 10 and drive the impeller 10 and the second keyway 12 to rotate; when the second keyway 12 is opposite to the positioning mechanism 25, the positioning mechanism 25 is inserted into the second keyway 12, and at this time the second clamping and rotating mechanism 23 stops driving the impeller 10 to rotate; afterwards, start the second translation mechanism 26 to drive the translation table 27, the lifting mechanism 28 and the clamping and flipping mechanism 30 to move, so that the clamping and flipping mechanism 30 is located above the impeller 10; afterwards, start the lifting mechanism 28 to drive the clamping and flipping mechanism 30 to move downward, so that the clamping and flipping mechanism 30 is inserted into the impeller 10; afterwards, start the clamping and flipping mechanism 30 to clamp the impeller 10; afterwards, start the lifting mechanism 28 to drive the clamping and flipping mechanism 30 and the impeller 10 to move upward, so that the impeller 10 is disengaged from the second clamping and rotating mechanism 23; afterwards, start the clamping and flipping mechanism 30 to drive the impeller 10 to flip 90 degrees, so that the impeller 10 faces the mandrel 9, and the connecting key inserted into the first keyway 11 faces the second keyway 12; afterwards, start the second translation mechanism 26 to drive the translation table 27 and the impeller 10 to move, so that part of the impeller 10 is sleeved on the outside of the mandrel 9, and part of the connecting key is inserted into the second keyway 12; afterwards, start the clamping and flipping mechanism 30 to disengage from the impeller 10, and start the second translation mechanism 26 to drive the clamping and flipping mechanism 30 to move away from the mandrel 9;Next, start the step-up and step-down mounting mechanism 22, align the step-up and step-down mounting mechanism 22 with the impeller 10, and make the step-up and step-down mounting mechanism 22 push the impeller 10 to move, so that the impeller 10 is integrally sleeved on the mandrel 9. At this time, all the connecting keys are embedded in the second key groove 12, thus completing the assembly of the impeller 10 and the mandrel 9.

[0051] By embedding the lifting and positioning mechanism 21 into the first key groove 11 and embedding the positioning mechanism 25 into the second key groove 12, the mandrel 9 and the impeller 10 are positioned to determine the relative position of the mandrel 9 and the impeller 10, so that the first key groove 11 and the second key groove 12 are opposite to each other, ensuring that the connecting keys can be simultaneously embedded in the first key groove 11 and the second key groove 12, thereby improving the assembly accuracy of the mandrel 9 and the impeller 10. With the above structure, when the impeller 10 is sleeved outside the mandrel 9, there is no need to rotate the impeller 10 to adjust the position of the second key groove 12, thus improving the assembly efficiency and accuracy of the product, and at the same time avoiding interference between the connecting keys and the impeller 10, so as to improve the quality of the product.

[0052] In the embodiment of the present invention, as Figure 1 shown, the first translation mechanism 17 includes: a first support plate 171, a first threaded hole, a first lead screw 172 and a first motor 173; two first support plates 171 are fixed on the workbench 13, and there is a distance between the two first support plates 171; the first threaded hole is provided with a first internal thread, and the first threaded hole is arranged in the translation plate 18; the outer wall of the first lead screw 172 is provided with a first external thread, and the two ends of the first lead screw 172 are respectively rotatably connected to the two first support plates 171, and the first lead screw 172 passes through the first threaded hole; the first motor 173 is provided with a first output shaft, the first motor 173 is fixed on the workbench 13, and the first output shaft of the first motor 173 is connected to the first lead screw 172; wherein, the first internal thread is adapted to the first external thread.

[0053] By fixing the two first support plates 171 on the workbench 13 and rotatably connecting the two ends of the first lead screw 172 to the two first support plates 171 respectively, the two first support plates 171 support the first lead screw 172, so that the first lead screw 172 can rotate between the two first support plates 171; by arranging the first threaded hole in the translation plate 18 and making the first lead screw 172 pass through the first threaded hole, the first lead screw 172 is threadedly connected to the translation plate 18, so that rotating the first lead screw 172 drives the translation plate 18 to move, thereby adjusting the position of the translation plate 18; by fixing the first motor 173 on the workbench 13 and connecting the first output shaft of the first motor 173 to the first lead screw 172, the first motor 173 can drive the first lead screw 172 to rotate, thus providing power for rotating the first lead screw 172.

[0054] In an embodiment of the present invention, as Figure 2 and Figure 15 shown, the first clamping and rotating mechanism 19 includes: a first slewing bearing 191, a first mounting bracket 192, a first cylinder 193, an adjusting block 194, a first clamping block 195, a first clamping groove 196, a first sliding groove 197, a first sliding block 198, a first connecting rod 199, a first limiting plate 200 and a first spring 201; the first slewing bearing 191 is installed on a side wall of the translation plate 18 close to the core shaft 9; the first mounting bracket 192 is installed on the first slewing bearing 191; the first cylinder 193 is provided with a first driving shaft, the first cylinder 193 is installed on a side wall of the translation plate 18 facing away from the core shaft 9, and the first driving shaft of the first cylinder 193 sequentially passes through the first slewing bearing 191 and the first mounting bracket 192; the cross section of the adjusting block 194 is trapezoidal, and the adjusting block 194 is rotationally connected to the first driving shaft of the first cylinder 193; the first clamping block 195 is provided with an inclined surface, two first clamping blocks 195 are placed on the side wall of the first mounting bracket 192, and the two first clamping blocks 195 are simultaneously in contact with the adjusting block 194; the first clamping groove 196 is arranged in the first clamping block 195, and the core shaft 9 is embedded in the first clamping groove 196; two first sliding grooves 197 are arranged on the side wall of the first mounting bracket 192; two first sliding blocks 198 are respectively connected to the two first clamping blocks 195, and the two first sliding blocks 198 are respectively embedded in the two first sliding grooves 197; two first connecting rods 199 pass through the first mounting bracket 192, and the two first connecting rods 199 are respectively connected to the two first sliding blocks 198; two first limiting plates 200 are respectively connected to the two first connecting rods 199, and the first limiting plate 200 is located outside the first mounting bracket 192; the first spring 201 is sleeved outside the first connecting rod 199, one end of the first spring 201 is connected to the first mounting bracket 192, and the other end of the first spring 201 is connected to the first limiting plate 200.

[0055] By installing the first slewing bearing 191 on the translation plate 18 and installing the first mounting bracket 192 on the first slewing bearing 191, it is achieved that the translation plate 18 can drive the first slewing bearing 191 and the first mounting bracket 192 to move, so as to realize the relative rotation between the first mounting bracket 192 and the translation plate 18; by installing the first cylinder 193 on the translation plate 18 and rotatably connecting the adjusting block 194 to the first driving shaft of the first cylinder 193, it is achieved that the translation plate 18 can drive the first cylinder 193 to move, so as to realize that the first cylinder 193 can drive the adjusting block 194 to move through the first driving shaft. By placing two first clamping blocks 195 on the side wall of the first mounting bracket 192 and making the two first clamping blocks 195 simultaneously fit with the adjusting block 194, it is achieved that when the first cylinder 193 drives the adjusting block 194 to move away from the mandrel 9, the adjusting block 194 can press the two first clamping blocks 195 to move to both sides, thereby increasing the distance between the two first clamping blocks 195 to facilitate the embedding of the mandrel 9 between the two first clamping blocks 195; by arranging the first clamping groove 196 in the first clamping block 195 and making the mandrel 9 embed in the first clamping groove 196, it is convenient for the first clamping block 195 to clamp the mandrel 9, thereby improving the stability of the mandrel 9. By arranging the first sliding groove 197 on the side wall of the first mounting bracket 192, connecting the first sliding block 198 to the first clamping block 195, and embedding the first sliding block 198 in the first sliding groove 197, it is achieved that the first clamping block 195 can move along the first sliding groove 197 through the first sliding block 198, thereby preventing the first clamping block 195 from shifting during movement and improving the stability of the first clamping block 195; by connecting the first connecting rod 199 to the first sliding block 198 and making the first connecting rod 199 pass through the first mounting bracket 192, it is achieved that the first sliding block 198 and the first connecting rod 199 move synchronously; by connecting the first limiting plate 200 to the first connecting rod 199, sleeving the first spring 201 on the outside of the first connecting rod 199, connecting one end of the first spring 201 to the first mounting bracket 192, and connecting the other end of the first spring 201 to the first limiting plate 200, it is achieved that the first mounting bracket 192 supports the first limiting plate 200 and the first connecting rod 199 through the first spring 201.

[0056] With the above structure, when the mandrel 9 is not inserted between the two first clamping blocks 195, the first cylinder 193 is activated to drive the adjusting block 194 to move away from the mandrel 9, so that the adjusting block 194 presses the two first clamping blocks 195 to move to both sides. Further, the first clamping blocks 195 drive the first limiting plate 200 to move outward through the first connecting rod 199. At this time, the first spring 201 is in a stretched state. When the mandrel 9 is inserted between the two first clamping blocks 195 and the mandrel 9 is in contact with the two first clamping blocks 195 at the same time, the first cylinder 193 is activated to drive the adjusting block 194 to move towards the mandrel 9. At this time, the first spring 201 resets and drives the first connecting rod 199 to move inward, so that the mandrel 9 is inserted into the two first clamping grooves 196 at the same time. Further, the elastic force of the first spring 201 is used to clamp the mandrel 9 by the two first clamping blocks 195. Then, the first slewing bearing 191 is rotated to drive the first mounting bracket 192 and the mandrel 9 to rotate, so as to adjust the orientation of the first key groove 11, and further ensure that the first key groove 11 faces upward, so as to facilitate the subsequent installation of the impeller 10 on the outside of the mandrel 9.

[0057] Specifically, a manipulator is installed on the support frame 14, and the manipulator is located above the mandrel 9. After the first key groove 11 faces upward, the connecting key is placed in the first key groove 11 through the manipulator.

[0058] In the embodiment of the present invention, as Figure 1 and Figure 2 shown, the first clamping and rotating mechanism 19 further includes: a first external tooth 202, a first mounting groove 203, a second motor 204 and a first gear 205. The first external tooth 202 is provided on the outer wall of the first slewing bearing 191. The first mounting groove 203 is provided in the translation plate 18. The second motor 204 is provided with a second output shaft, and the second motor 204 is installed in the first mounting groove 203. The first gear 205 is sleeved on the outside of the second output shaft of the second motor 204. The first gear 205 is located below the first slewing bearing 191, and the first gear 205 meshes with the first external tooth 202.

[0059] By arranging the first mounting groove 203 within the translation plate 18 and installing the second motor 204 in the first mounting groove 203, the second motor 204 can be hidden within the translation plate 18, and at the same time, the translation plate 18 can support the second motor 204. By arranging the first external teeth 202 on the outer wall of the first slewing bearing 191, sleeving the first gear 205 outside the second output shaft of the second motor 204, and meshing the first gear 205 with the first external teeth 202, the second motor 204 can drive the first gear 205 to rotate, thereby enabling the first gear 205 to mesh with the first external teeth 202 and drive the first slewing bearing 191 to rotate, and further providing power for the rotating mandrel 9.

[0060] In an embodiment of the present invention, as Figure 1 and Figure 3 shown, the lifting and positioning mechanism 21 includes: a first receiving groove 211, a second cylinder 212, a first lifting plate 213, a first positioning plate 214, a second connecting rod 215, a second spring 216, and a second limiting plate 217. The first receiving groove 211 is arranged at the top of the workbench 13 and is located below the first key groove 11. The second cylinder 212 is provided with a second driving shaft, the second cylinder 212 is installed at the bottom of the workbench 13 and is located below the first receiving groove 211. The first lifting plate 213 is connected to the second driving shaft of the second cylinder 212 and is located below the first key groove 11. The first positioning plate 214 is located above the first lifting plate 213, and at least part of the first positioning plate 214 is embedded in the first key groove 11. One ends of the two second connecting rods 215 are simultaneously connected to the first positioning plate 214, and the other ends of the two second connecting rods 215 pass through the first lifting plate 213. The second spring 216 is sleeved outside the second connecting rod 215, one end of the second spring 216 is connected to the first positioning plate 214, and the other end of the second spring 216 is connected to the first lifting plate 213. The second limiting plate 217 is simultaneously connected to the other ends of the two second connecting rods 215 and is wound around the outside of the second driving shaft of the second cylinder 212.

[0061] By installing the second cylinder 212 at the bottom of the workbench 13, the workbench 13 can support the second cylinder 212; by providing the first receiving groove 211 at the top of the workbench 13, connecting the first lifting plate 213 to the second drive shaft of the second cylinder 212, and positioning the first receiving groove 211 and the first lifting plate 213 below the first keyway 11, the first receiving groove 211, the first lifting plate 213, and the first keyway 11 are in the same vertical plane, so that when the second cylinder 212 drives the first lifting plate 213 to move up and down, the first lifting plate 213 can be inserted into the first receiving groove 211, and thus the first lifting plate 213 can be hidden inside the workbench 13. By positioning the first positioning plate 214 above the first lifting plate 213 and inserting at least part of the first positioning plate 214 into the first keyway 11, the first positioning plate 214 can position the first keyway 11 and the mandrel 9; by connecting one end of two second connecting rods 215 to the first positioning plate 214 simultaneously and passing the other ends of the two second connecting rods 215 through the first lifting plate 213, the two second connecting rods 215 move up and down synchronously with the first positioning plate 214; by sleeving the second spring 216 on the outside of the second connecting rod 215, connecting one end of the second spring 216 to the first positioning plate 214, and connecting the other end of the second spring 216 to the first lifting plate 213, the first lifting plate 213 supports the first positioning plate 214 through the second spring 216; by connecting the second limiting plate 217 to the other ends of the two second connecting rods 215 simultaneously and winding the second limiting plate 217 around the outside of the second drive shaft of the second cylinder 212, the second limiting plate 217 moves synchronously with the two second connecting rods 215, and at the same time, interference between the second limiting plate 217 and the second drive shaft of the second cylinder 212 can be avoided.

[0062] With the above structure, after the first clamping and rotating mechanism 19 clamps the mandrel 9, the second cylinder 212 is started, so that the second cylinder 212 drives the first lifting plate 213 and the first positioning plate 214 to move upward, and makes the first positioning plate 214 fit against the outer wall of the mandrel 9 (the first positioning plate 214 does not embed into the first key groove 11). At this time, the second spring 216 is compressed; then, the first clamping and rotating mechanism 19 is started, so that the first clamping and rotating mechanism 19 drives the mandrel 9 to rotate. When the first key groove 11 is opposite to the first positioning plate 214, the second spring 216 resets and drives the first positioning plate 214 to embed into the first key groove 11, so that the mandrel 9 stops rotating. At this time, the first clamping and rotating mechanism 19 stops; then, the second cylinder 212 is started, so that the second cylinder 212 drives the first lifting plate 213 and the first positioning plate 214 to move downward, so that the first positioning plate 214 disengages from the first key groove 11, and drives the first lifting plate 213 and the first positioning plate 214 to embed into the first receiving groove 211 to avoid interference between the first positioning plate 214 and other components in the future; then, the first clamping and rotating mechanism 19 is started, so that the first clamping and rotating mechanism 19 drives the mandrel 9 to rotate 90 degrees, so that the first key groove 11 faces upward, facilitating the staff to place the connecting key in the first key groove 11.
