[0043] like Figures 1 to 8 As shown, this utility model provides a positioning auxiliary tooling for assisting the connection between a tensioner and a screw. The positioning auxiliary tooling includes: a first support 100, a first adjustment component 200, and a second adjustment component 300. The first adjustment component 200 includes a second support 210, a placement frame 220, and a first driving member 230. The second support 210 is rotatably connected to the first support 100. The placement frame 220 is used to mount the tensioner. Both the placement frame 220 and the first driving member 230 are mounted on the second support 210. The first driving member 230 is used to drive the placement frame 220 to rotate around a first axis 1. The second adjustment component 300 is mounted on the first support 100 and includes a second driving member 310. The second driving member 310 is used to drive the second support 210 to rotate around a second axis 2. The second axis 2 is perpendicular to the vertical direction X and intersects with the first axis 1.

[0044] The first support 100 is used to provide mounting support for the first adjusting assembly 200 and the second adjusting assembly 300, and can be kept relatively static with the ground. The user can drive the placement rack 220 to rotate relative to the second support 210 through the first driving member 230. Since the stretcher is mounted on the placement rack 220 and located at the eccentric side of the first axis 1, the stretcher can be driven to revolve around the first axis 1, and the relative position of the stretcher and the screw rod can be adjusted to facilitate alignment with the screw rod. The user can also drive the first adjusting assembly 200 as a whole to rotate around the second axis 2 relative to the first support 100 through the second driving member 310, so as to adjust the pitch angle of the first adjusting assembly 200 and facilitate the installation of the stretcher in the first adjusting assembly 200. In this way, the safety of the installation of the stretcher and the positioning auxiliary tool is improved, the accuracy of the alignment of the stretcher and the corresponding screw rod is improved, and the work efficiency is also improved.

[0045] Preferably, the first axis 1 and the second axis 2 are arranged perpendicularly.

[0046] Preferably, the axis of the interface of the stretcher for interfacing with the screw rod is parallel to the first axis 1.

[0047] In use, the first adjusting assembly 200 includes a first position and a second position, which are switched by rotating the first adjusting assembly 200 around the second axis 2. When in the first position, the first axis 1 is perpendicular to the horizontal plane, and the stretcher is installed on the placement rack 220 at this time, and the stretcher can be placed relatively stably on the placement rack 220 under the action of gravity. When in the second position, the first axis 1 is parallel to the horizontal plane, and the interface of the stretcher is also horizontally oriented, which can be inserted with the screw rod in the horizontal direction. Then, the placement rack 220 is rotated by the first driving member 230 to align the stretcher with the screw rod, and the first support 100 is moved along the first axis 1, so that the stretcher on the placement rack 220 is inserted with the corresponding screw rod.

[0048] Optionally, the first driving member 230 and / or the second driving member 310 is a hand wheel.

[0049] Illustratively, the first adjusting assembly 200 can rotate 360° around the second axis 2 relative to the first support 100.

[0050] Illustratively, the placement rack 220 can rotate 360° around the first axis 1 relative to the second support 210.

[0051] Further, a plurality of stretchers can be mounted on the placement rack 220. Preferably, the plurality of stretchers correspond one-to-one to a plurality of screw rods arranged in the electrolytic cell. In this way, after the placement rack 220 is adjusted once, all the stretchers can be inserted one-to-one with all the screw rods, thereby improving the work efficiency.

[0052] Optionally, the second support 210 comprises a circular guide rail, the placing rack 220 is in a circular shape, the placing rack 220 is installed on the inner side or the outer side of the circular guide rail, and the center line of the circular guide rail, the center line of the placing rack 220 and the first axis 1 coincide. In this way, the circular placing rack 220 has a relatively simple structure, and can reduce its own mass to a certain extent, thereby reducing the output power required by the first driving member 230 for driving the placing rack 220 to move relative to the second support 210. Moreover, the circular placing rack 220 is connected with the circular guide rail, which can standardize the rotation track of the placing rack 220 around the first axis 1, and the second support 210 supports the placing rack 220 more widely, which can avoid the swinging of the placing rack 220 relative to the second support 210, so as to connect the stretcher with the screw rod.

[0053] As shown in the examples of FIGS. 1 and 2, the placing rack 220 is in a circular shape, which comprises a first blocking edge 2211 and a second blocking edge 2212. The first blocking edge 2211 and the second blocking edge 2212 are spaced apart along the first axis 1 and are relatively fixed. The first blocking edge 2211 and the second blocking edge 2212 form an insertion slot therebetween, and the circular guide rail of the second support 210 is inserted into the insertion slot. The first blocking edge 2211 and the second blocking edge 2212 are used to limit the relative movement of the placing rack 220 and the second support 210 along the first axis 1, thereby reducing the risk of disassembly of the placing rack 220 and the second support 210 along the first axis 1. Figure 7 Figure 8 As shown in the examples of FIGS. 1 and 2, the placing rack 220 is in a circular shape, which comprises a first blocking edge 2211 and a second blocking edge 2212. The first blocking edge 2211 and the second blocking edge 2212 are spaced apart along the first axis 1 and are relatively fixed. The first blocking edge 2211 and the second blocking edge 2212 form an insertion slot therebetween, and the circular guide rail of the second support 210 is inserted into the insertion slot. The first blocking edge 2211 and the second blocking edge 2212 are used to limit the relative movement of the placing rack 220 and the second support 210 along the first axis 1, thereby reducing the risk of disassembly of the placing rack 220 and the second support 210 along the first axis 1.

[0054] In other embodiments, the second support 210 comprises a third blocking edge and a fourth blocking edge, and the circular guide rail is clamped between the third blocking edge and the fourth blocking edge. An insertion slot is formed between the circular guide rail, the third blocking edge and the fourth blocking edge, and the placing rack 220 is inserted into the insertion slot. The third blocking edge and the fourth blocking edge are formed on the second support 210, and the third blocking edge, the fourth blocking edge and the circular guide rail form the insertion slot, and the placing rack 220 is at least partially inserted into the insertion slot.

[0055] It should be noted that the insertion direction of the circular guide rail and the insertion slot is arranged at an angle to the extension direction of the first axis 1. Preferably, the insertion direction of the circular guide rail and the insertion slot is arranged at an angle of 90° to the extension direction of the first axis 1.

[0056] Optionally, the first adjusting assembly 200 further comprises a driving gear 241 and a driven gear 242. The driving gear 241 is connected with the output end of the first driving member 230, the driven gear 242 is coaxially fixed with the placing rack 220 and is in a circular shape, and the driving gear 241 and the driven gear 242 are in meshing transmission.

[0057] ​Exemplarily, the driven gear 242 and the placement rack 220 are both annular, coaxially arranged, and the driven gear 242 is fixed to the axial end surface of the placement rack 220, and the driving gear 241 is coaxially connected with the output end of the first driving member 230. When the first driving member 230 is started, the first driving member 230 can drive the driven gear 242 to rotate through the driving gear 241, thereby driving the second support 210 to rotate around the first axis 1, thereby achieving the purpose of moving the second support 210 carrying the stretcher around the first axis 1 for position adjustment. In this way, the transmission mechanism composed of the driving gear 241 and the driven gear 242 has a relatively simple structure and high reliability. The annular design of the driven gear 242 can reduce its own mass, thereby reducing the mass of the assembly of the driven gear 242 and the placement rack 220. This can not only reduce the demand for output power of the first driving member 230 for driving the assembly of the placement rack and the driven gear 242, but also reduce the load between the driving gear 241 and the driven gear 242, thereby prolonging the service life.

[0058] Exemplarily, the second support 210 further comprises a second mounting seat 215, and the first driving member 230 is mounted on the second mounting seat 215.

[0059] Optionally, the second support 210 is annular, the placement rack 220 is mounted on the inner side of the second support 210, and the center line of the second support 210, the center line of the placement rack 220 and the first axis 1 coincide. In this way, the second support 210 has a simple structure and is easy to manufacture. Moreover, the mass of the second support 210 can be reduced to some extent, thereby reducing the output power required by the second driving member 310 when driving the first adjustment assembly 200. Moreover, the butt joint of the placement rack 220 and the second support 210 can standardize the rotation track of the placement rack 220 around the first axis 1. Moreover, the second support 210 supports the placement rack 220 in a larger range, and can avoid the swing of the placement rack 220 relative to the second support 210, so as to facilitate the butt joint of the stretcher and the screw rod.

[0060] As shown in Figure 6 Optionally, the second support 210 comprises a plurality of first support sub-members 211, adjacent two first support sub-members 211 are detachably connected, and the plurality of first support sub-members 211 are connected end to end to form an annular structure, and the placement rack 220 is arranged on the inner side of the annular structure. In this way, the second support 210 is formed by splicing a plurality of first support sub-members 211, which has relatively low process requirements compared with integral molding. Moreover, the split design of the second support 210 facilitates the assembly of the second support 210 and the placement rack 220.

[0061] Exemplarily, the second support 210 comprises a first support sub 211 and a fixing member 216, the first support sub 211 is provided in two pieces, the first support sub 211 is in the shape of a circular arc, the two pieces of the first support sub 211 are mirror-symmetrically connected to form a closed circular ring, and the fixing member 216 is connected to the two pieces of the first support sub 211 at the joint. In this way, the two pieces of the first support sub 211 can be clamped to the placement rack 220 along the radial direction, and then fixed.

[0062] In other embodiments, the second support 210 comprises at least two second support subs arranged side by side along the first axis 1, the adjacent two second support subs are detachably connected, and the placement rack 220 is clamped between the at least two second support subs. Exemplarily, the second support sub is provided in three pieces, for example, the second support sub comprises a third stop edge, a fourth stop edge and a circular ring guide rail, and the third stop edge, the fourth stop edge and the circular ring guide rail form the second support 210. The placement rack 220 is clamped between the third stop edge and the fourth stop edge in the extension direction of the first axis 1.

[0063] Optionally, the second adjusting assembly 300 further comprises a speed reducer 320, and the second driving member 310 drives the second support 210 through the speed reducer 320. In this way, since the speed reducer 320 can convert the high rotational speed at the input end into low rotational speed output, the user can more accurately adjust the position of the first adjusting assembly 200, so as to dock the stretcher with the screw rod. Further, the speed reducer 320 can also increase the torque, and can reduce the output torque of the first driving member 230 for driving the first adjusting assembly 200 to rotate relative to the first support 100.

[0064] Exemplarily, the first support 100 comprises a first mounting seat 140, and the speed reducer 320 is mounted on the first mounting seat 140.

[0065] Optionally, a rolling member 212 is arranged between the second support 210 and the placement rack 220. In this way, the second support 210 and the placement rack 220 form rolling friction through the rolling member 212, which can reduce the friction coefficient between the second support 210 and the placement rack 220, and further reduce the output power required by the first driving member 230 for driving the placement rack 220 to rotate relative to the second support 210.

[0066] Exemplarily, the second support 210 is in the shape of a circular ring, a first roller is mounted on the inner side wall of the second support 210, the first roller is rotationally connected with the second support 210, and the rotational axis of the first roller is parallel to the first axis 1. The first roller is the rolling member 212, and the circumferential wall of the first roller is in contact with the outer side wall of the placement rack 220. When the placement rack 220 rotates relative to the second support 210, the placement rack 220 can drive the first roller to rotate.

[0067] Furthermore, the inner wall of the second support 210 is provided with a groove, and the first roller is disposed in the groove via the second rotating shaft 214. The first roller extends at least partially out of the groove for contact with the placement rack 220. In this way, the gap between the second support 210 and the placement rack 220 can be reduced.

[0068] Furthermore, the second bracket 210 is equipped with a plurality of first rollers, and the plurality of first rollers are evenly distributed around the first axis 1.

[0069] Furthermore, along the direction perpendicular to the first axis 1 and the second axis 2, that is, along Figure 1 In the extension direction of the straight line 3, the first rollers are arranged relatively densely at both ends of the second support 210, and the straight line 3 passes through the axis of the second support 210. Thus, when the first axis 1 is parallel to the horizontal plane, the straight line 3 is parallel to the direction of gravity. The second support 210 supports the placement frame 220 in the direction of gravity. At the lower end of the straight line 3, the force exerted by the placement frame 220 on the second support 210 is most concentrated. The concentrated arrangement of the first rollers can distribute the load relatively evenly and avoid local stress concentration.

[0070] Furthermore, a second roller can be installed on the axial end face of the second bracket 210. The second roller is rotatably connected to the second bracket 210, and the rotation axis of the second roller is perpendicular to the first axis 1. Preferably, the rotation axis of the second roller is arranged radially along the second bracket 210. The second roller is a rolling element 212. The circumferential wall of the second roller supports the first stop 2211 and / or the second stop 2212 of the placement frame 220 in the direction of the first axis 1, thereby reducing the frictional force generated at the contact surface between the placement frame 220 and the second bracket 210 in the extension direction of the first axis 1.

[0071] In other embodiments, the second bracket 210 has a plurality of protrusions with arc surfaces on its contact surface with the placement rack 220, or the placement rack 220 has a plurality of protrusions with arc surfaces on its contact surface with the second bracket 210, thereby reducing the contact area between the second bracket 210 and the placement rack 220, thereby reducing friction.

[0072] Optionally, the placement rack 220 includes a support body 221, a placement sleeve 222, and a locking member 223. The support body 221 is rotatably connected to the second bracket 210. The placement sleeve 222 is installed on the support body 221. The opening direction of the placement sleeve 222 is parallel to the first axis 1. The locking member 223 is movably connected to the placement sleeve 222.

[0073] Exemplarily, the placing sleeve 222 is provided with a receiving cavity 2221 along the first axis 1, and the stretcher can be loaded into or out of the placing sleeve 222 along the first direction. Specifically, the locking piece 223 is a drop stopper, and each placing sleeve 222 is provided with two drop stoppers which are threadedly connected with the placing sleeve 222. The feeding amount of the drop stopper in the receiving cavity 2221 can be changed by rotating the drop stopper. The axis of the drop stopper is perpendicular to the first axis 1, and the two drop stoppers are oppositely arranged. When it is needed to lock the stretcher in the placing sleeve 222, the two drop stoppers are close to each other, and the stretcher is clamped between the two drop stoppers. When it is needed to release the stretcher from the placing sleeve 222, at least one drop stopper can be loosened.

[0074] Further, the placing rack 220 is provided with a plurality of placing sleeves 222 which are arranged around the first axis 1.

[0075] Further, the supporting body 221 is provided with a sliding groove around the first axis 1, and the placing sleeve 222 is connected with a sliding block which can slide or be locked in the sliding groove. In this way, the spacing between the placing sleeves 222 can be adjusted to adapt to the working scene.

[0076] Further, the supporting body 221 is provided with a plurality of mounting positions for mounting the placing sleeves 222, and the placing sleeves 222 are detachably connected with the supporting body 221 at the mounting positions.

[0077] Optionally, the first support 100 comprises a first supporting member 110 and a second supporting member 120, and the second supporting member 120 is connected with two first supporting members 110 which are symmetrically arranged, and the two first supporting members 110 are rotationally connected with the second support 210.

[0078] Exemplarily, as shown in Figure 2 the first support 100 is a gantry structure comprising a first supporting member 110 and a second supporting member 120. Specifically, two first supporting members 110 are provided, and the two first supporting members 110 are mirror-symmetrically arranged in the second horizontal direction Z and are connected at the high ends in the vertical direction X through the second supporting member 120. The two first supporting members 110 and the second supporting member 120 enclose an installation space in which the first adjusting assembly 200 is installed. In this way, the first support 100 of the gantry structure has a relatively simple structure, is convenient for production and manufacturing, and forms protection outside the first adjusting assembly 200 by the first supporting member 110 and the second supporting member 120.

[0079] Further, the first rotating shaft 213 of the second support 210 in the second horizontal direction Z is hingedly connected with the corresponding first supporting member 110. The second adjusting assembly 300 is installed on one of the first supporting members 110, and the output end of the second driving member 310 is in transmission connection with the first rotating shaft 213.

[0080] Further, after the first adjusting assembly 200 is installed on the first support 100, the overall gravity center of the tooling is located at a relatively high position, and when the stretchers are assembled with the screw rod, the first support 100 always has a tendency to tilt along the first axis 1 during movement. Therefore, in the embodiment, the first support 110 includes a first rod 111 and a second rod 112. The first rod 111 is parallel to the vertical direction X in the axial direction, the high end of the first rod 111 is connected to the second support 120, the low end of the first rod 111 is connected to the second rod 112, the second rod 112 is parallel to the first horizontal direction Y in the axial direction, and the connection point of the first rod 111 and the second rod 112 is located in the middle of the second rod 112. In this way, by arranging the second rod 112, the supporting area of the first support 100 can be increased, thereby maintaining the stability of the first support 100.

[0081] Further, the first support 110 further includes a third rod 113, and a plurality of third rods 113 are arranged on opposite sides of the first rod 111 in the first horizontal direction Y. The third rod 113 is arranged obliquely, and the two ends of the third rod 113 are connected to the first rod 111 and the second rod 112, respectively. In the projection in the second horizontal direction Z, the third rod 113, at least part of the first rod 111, and at least part of the second rod 112 form a triangle. In this way, the third rod 113 can serve as a reinforcing rib of the first rod 111 and the second rod 112, thereby strengthening the structural strength of the first rod 111 and the second rod 112.

[0082] Optionally, the second support 210 is rotatably connected to the first support 100 through a bearing 130. In this way, by arranging the bearing 130, the friction between the second support 210 and the first support 100 is reduced, thereby reducing the output power of the second driving member 310 for driving the first adjusting assembly 200 to rotate around the second axis 2.

[0083] Illustratively, the two first supports 110 of the first support 100 are provided with hinge holes 114 along the second axis 2, and the first rotating shafts 213 on opposite sides of the second support 210 are respectively inserted into the corresponding hinge holes 114 to realize the hinging of the first support 110. Each first support 110 is provided with a bearing 130 in the axial direction of the hinge hole 114, the outer ring of the bearing 130 is fixed to the first support 110, the inner hole of the inner ring of the bearing 130 is coaxially arranged with the hinge hole 114, and the first rotating shaft 213 of the second support 210 is simultaneously inserted into the inner hole of the inner ring of the bearing 130.

[0084] In other embodiments, the bearing 130 is installed in the hinge hole 114, the outer ring of the bearing 130 is fixed to the first support 110, and the first rotating shaft 213 of the second support 210 is inserted into the inner ring of the bearing 130.

[0085] Optionally, the positioning auxiliary tool further comprises casters 400, which are installed at the bottom of the first support 100.

[0086] Specifically, the bottom of the first support 100 is provided with n casters 400, n≥3, and axes of m casters 400 are located in the same plane, n≥m≥3, and the m casters 400 are arranged non-collinearly.

[0087] In this way, the bottom of the first support 100 is provided with at least three casters 400, and the three casters 400 are arranged coplanarly but non-collinearly, so that the three casters 400 can determine a plane, thereby ensuring that the first support 100 can be stably placed on a support surface parallel to the plane determined by the casters 400.

[0088] In the embodiment, the bottom of the first support 100 is provided with four casters 400, and the four casters 400 are arranged in a matrix, i.e., two casters 400 are arranged on each first support 110.

[0089] Further, the caster 400 is provided with a parking mechanism, which can lock the wheel body so that the wheel body remains relatively stationary with the first support 100, thereby keeping the positioning auxiliary tool stably parked at a certain station, and the parking mechanism can also release the wheel body so that the wheel body can rotate relative to the first support 100, so as to move the positioning auxiliary tool from one station to another station.

[0090] Further, the caster 400 is a universal wheel, so as to facilitate steering of the positioning auxiliary tool.

[0091] The use method of the positioning auxiliary tool provided by the utility model is roughly as follows:

[0093] S12, place the stretcher in the corresponding placing sleeve 222, and the axis of the butt joint of the stretcher for butt joint with the screw is parallel to the first axis 1;

[0094] S13, lock the stretcher in the placing sleeve 222 by the locking piece 223;

[0095] S21, adjust the first adjusting assembly 200 to a second position, i.e., the first axis 1 is parallel to the horizontal direction, at this time, the butt joint axis of the stretcher is parallel to the axis of the screw on the electrolytic cell plate;

[0096] S22, contact the parking state of the caster 400, push the first support 100, so that the whole positioning auxiliary tool is close to the electrolytic cell plate;

[0097] S23, after reaching the preset position, rotate the placing rack 220, so that the stretcher corresponds to the corresponding screw rod one by one, that is, the butt joint axis of the stretcher is collinear with the axis of the screw rod on the electrolytic cell plate at this time;

[0098] S31, push the first support 100 again, so that the screw rod is inserted into the stretcher, the restraint of the locking piece 223 on the stretcher is released, so that the stretcher can be taken out of the placing sleeve 222;
