Description

Technical Field

[0001] The present application relates to the technical field of clamping equipment, and in particular to a clamping device for gluing an air-suspended axle. Background Art

[0002] Some connectors are usually welded on the axle of a car. If water vapor or dust enters the connecting part between the connector and the axle, it will easily affect the connection strength. Therefore, it is usually necessary to apply sealant to the gap between the connector and the axle to reduce the entry of water vapor and dust and ensure the connection strength.

[0003] Most axles on the market are manually coated with sealant, which is inefficient, so some automatic gluing systems have emerged. The automatic gluing system includes a clamping device and a gluing device; the clamping device includes a rotating table and a supporting table, and cylinders are provided on the rotating table and the supporting table, and ejector pins are provided on the ends of the cylinders; the two cylinders are used to press the two ends of the axle. The gluing device includes a mechanical arm and a gluing part, which is aligned with the part to be glued on the axle, and the axle can be rotated to complete the rapid application of sealant.

[0004] The axle usually weighs hundreds of kilograms and is fixed by two cylinders and a thimble at both ends of the axle. If the air pressure in the cylinder is unstable or there is a leak, there will be insufficient clamping force, causing the axle to fall and damage the axle. Summary of the invention

[0005] In order to reduce the possibility of accidental falling of the axle due to insufficient clamping force, the present application provides a clamping device for gluing an air-suspended axle.

[0006] The present application provides a clamping device for gluing an empty suspension axle, which adopts the following technical solution: A clamping device for gluing an empty suspension axle, comprising a supporting mechanism, comprising a base, a rotating platform and a supporting platform, wherein the rotating platform and the supporting platform are respectively arranged at two ends of the base, the rotating platform is rotatably connected to the base, the rotating platform and the supporting platform are both provided with a mounting seat, the mounting seat is provided with a notch, and the rotating platform and the supporting platform are both provided with a cylinder; The protection mechanism comprises a round table, a sleeve, a protection rope, a connecting piece and an anti-rotation assembly, wherein the round table is arranged on a rotating table, the sleeve is rotatably sleeved on the outer side of the round table, the protection rope is passed through a mounting seat on the rotating table, and the connecting piece is used to detachably connect the end of the protection rope to the sleeve; The anti-rotation assembly includes a counterweight block, a bag body, a branch pipe, a limit piece and a blocking component. A receiving groove is opened inside the truncated table, and the counterweight block is slidably arranged in the receiving groove. The bag body is arranged between the counterweight block and the inner wall of the receiving groove. One end of the branch pipe is connected to the bag body, and the other end of the branch pipe is closed. The limit piece is slidably arranged in the sleeve, and the limit piece is fixedly connected to the closed end of the branch pipe, so that when the notch on the mounting seat faces downward, the counterweight block slides downward and squeezes the bag body to make one end of the limit piece slide into the rotating table, and the blocking component is used to limit the rotation of the limit piece.

[0007] By adopting the above technical solution, when the clamping force of the cylinder is insufficient, the anti-rotation component can prevent the sleeve from rotating, thereby preventing the protective rope from loosening and preventing the axle from falling due to insufficient clamping force of the cylinder; when the notch of the counterweight block on the mounting seat is facing downward, it moves downward under the action of gravity, squeezing the bag body to generate pressure, pushing the limit piece to insert into the rotating table to form a physical lock, thereby limiting the rotation of the sleeve relative to the rotating table, fixing the state of the protective rope, and protecting the axle; since the receiving groove is opened in the round table, the receiving groove can rotate with the rotating table, and the rotation of the sleeve will not affect the state of the receiving groove That is, while it is convenient to rotate the sleeve to tighten the protective rope, the counterweight block can also slide as needed; when the notch on the mounting seat is facing upward, the sleeve can rotate freely, thereby facilitating the tightening of the protective rope; when the notch on the mounting seat is facing downward, the rotation of the sleeve relative to the turntable is restricted, thereby achieving protection of the axle. Therefore, the anti-rotation component can adjust its working state according to the state of the turntable, without the need for operator control, which helps to simplify the operation; the sliding of the counterweight block can also dynamically adjust the center of gravity distribution of the device, reduce the unbalanced vibration caused by the rotation of the turntable, and improve the stability of the device operation.

[0008] Optionally, an annular groove for inserting a limit member is provided on the rotating table, and the annular groove is coaxially arranged with the sleeve. The blocking component includes a baffle and a first spring. The baffle is arranged along the axial direction of the sleeve, and the baffle is slidably connected in the annular groove along its own length direction. There are multiple baffles and they are arranged in a circular array. Two adjacent baffles resist each other, and the first spring is fixedly connected between the baffle and the bottom wall of the annular groove.

[0009] By adopting the above technical solution, when the notch on the mounting seat on the rotating table faces downward, the limiting piece is partially inserted into the annular groove. At this time, the blocking strips in the annular groove are pressed against the two sides of the connecting strip, thereby limiting the rotation of the sleeve relative to the rotating table, thereby preventing the protective rope from loosening and achieving protection of the axle; since there are multiple blocking strips and they are pressed against each other, even after the sleeve rotates, the rotation of the sleeve relative to the rotating table can still be limited.

[0010] Optionally, a ratchet is provided on the circular table, a pawl is rotatably connected to the inner wall of the sleeve, a torsion spring is connected between the pawl and the sleeve, and the torsion spring makes the pawl press against the ratchet so that the sleeve can only rotate in one direction relative to the circular table.

[0011] By adopting the above-mentioned technical scheme, the sleeve can only rotate in one direction relative to the table. After the sleeve is rotated to tighten the protective rope, the rotation of the sleeve can be limited by the cooperation of the ratchet and the pawl, thereby maintaining the tensioned state of the protective rope; after the limiting member is subsequently inserted into the annular groove, the rotation of the sleeve can be limited. At this time, the protective rope is still in a tensioned state, so it is not easy for the protective rope to relax after being subjected to force, thereby ensuring the protective effect; the ratchet pawl cooperates with the limiting member to enhance the limiting effect on the rotation of the sleeve, thereby improving the load-bearing capacity and protective performance of the device.

[0012] Optionally, a hemispherical groove is provided on the counterweight block, a sliding groove is provided on the inner wall of the accommodating groove and is arranged along the sliding direction of the counterweight block, and a ball is arranged between the hemispherical groove and the sliding groove.

[0013] By adopting the above technical solution, the friction force on the counterweight block during the sliding process can be reduced, so that the counterweight block can slide more smoothly, thereby improving the reliability of the operation of the device; the setting of the ball can also reduce the wear of components caused by friction and ensure the service life of the device.

[0014] Optionally, a flexible buffer block is provided at one end of the counterweight block away from the bag body. When the notch on the mounting seat on the rotating table faces downward, the bag body is located below the counterweight block. At this time, the bag body is in a compressed state and the counterweight block and the bottom wall of the accommodating groove are spaced apart.

[0015] By adopting the above technical solution, the buffer block can play a buffering role during the sliding process of the counterweight block, avoiding hard collision between the counterweight block and the bottom wall of the accommodating groove, thereby reducing the impact and noise caused by the collision, further protecting the components of the device, and improving the stability and service life of the device; in addition to being able to drive the limit piece to slide, the bag body can also support the counterweight block, thereby buffering the side of the counterweight block away from the buffer block through the bag body, thereby realizing protection of the counterweight block.

[0016] Optionally, elastic ropes are provided at both ends of the protective rope, and the connecting piece is provided between the elastic rope and the sleeve.

[0017] By adopting the above technical solution, the setting of the elastic rope can increase the overall flexibility of the protective rope, effectively absorb vibration energy when the axle shakes slightly, and avoid the protective rope from breaking due to excessive rigidity; the elastic rope can also increase the tensioning effect of the protective rope in the initial state; when the axle is glued, since the elastic rope is elastic, it is easy to cancel the connection between the elastic rope and the sleeve, and the operation is more convenient; in addition, the limiter includes a connecting ring and a connecting strip. When the connecting strip and the baffle strip in the annular groove are not aligned, each connecting strip will push the two baffle strips to slide inwardly of the annular groove. At this time, the baffle strip cannot rotate the connecting strip. The sleeve is rotated at a smaller angle, so that the connecting strip is aligned with the baffle strip. At this time, the first spring can make part of the baffle strip slide outward, so that each connecting strip is abutted against two baffle strips on both sides. At this time, the baffle strip can limit the rotation of the connecting strip and the connecting ring, thereby preventing the protective rope from continuing to relax. That is, the setting of the elastic rope can reduce the adverse effects caused by the misalignment of the connecting strip and the baffle strip, which helps to ensure the protective effect.

[0018] Optionally, a mounting groove is provided on the sleeve, a positioning column is slidably provided in the mounting groove, the end of the positioning column located outside the mounting groove is hemispherical, a second spring is connected between the positioning column and the inner wall of the mounting groove, a positioning groove is provided on the rotating table, and the positioning grooves are provided in plurality and arranged in a circular array, and the second spring is used to make the hemispherical end of the positioning column press tightly against the positioning groove.

[0019] By adopting the above technical solution, before applying the glue, rotate the sleeve to tighten the protective rope, and then continue to rotate the sleeve. At this time, the elastic rope is stretched. When a pause is felt, it indicates that the hemispherical end of the positioning column is pressed tightly against the positioning groove. At this time, the limit piece and the baffle are in a completely aligned state. Therefore, after the limit piece slides into the annular groove, the limiting effect of the limit piece can be guaranteed.

[0020] Optionally, a limiting mechanism is provided on the rotating platform, and the limiting mechanism includes a latch and a driving member. The latch is slidably provided on the rotating platform, one end of the latch is used to be inserted into a clamping hole on the axle, and the driving member is used to drive the latch to slide.

[0021] By adopting the above technical solution, the driving member drives the pin to be inserted into the clamping hole on the axle, thereby limiting the rotation of the axle relative to the rotating table, thereby helping to ensure the gluing effect on the axle.

[0022] Optionally, a mounting bracket is fixedly provided at the movable end of the driving member, and the latch is detachably connected to the mounting bracket.

[0023] By adopting the above technical solution, the pin can be detachably arranged, which makes it easy to replace the appropriate pin according to axles of different specifications, thereby improving the adaptability and maintenance convenience of the clamping device.

[0024] Optionally, one end of the base is fixedly connected to a first support, the other end of the base is slidably connected to a second support, the rotating table is rotatably connected to the first support, and the supporting platform is fixedly connected to the second support.

[0025] By adopting the above technical solution, the sliding adjustment of the support platform can be realized, thereby adapting to axles of different lengths and improving the versatility and flexibility of the device.

[0026] In summary, this application includes the following beneficial technical effects: 1. The protection mechanism can maintain the protection rope in a tensioned state through the cooperation of the protection rope and the anti-rotation component. When the clamping force of the cylinder is insufficient, the position of the axle can be limited by the protection rope to prevent the axle from accidentally falling.

[0027] 2. In the initial state, the sleeve can rotate freely, which is convenient for tightening the protective rope; as the turntable rotates, the limit piece can automatically slide out through the cooperation of the counterweight block, the bag body and the branch pipe, thereby limiting the rotation of the sleeve relative to the turntable, fixing the state of the protective rope, and realizing protection of the axle; the turntable continues to rotate, and the sleeve can be automatically unlocked; therefore, during the clamping process, the operator only needs to wrap the protective rope around the axle, connect the protective rope and the sleeve, and then rotate the sleeve to tighten the protective rope. No additional operation is required to limit the rotation of the sleeve, and the operation process is relatively simple.

[0028] 3. The protection rope and the sleeve cooperate to make the device easy to adapt to axles of different diameters, and the device has stronger applicability.

[0029] 4. The setting of the ratchet and the pawl can limit the rotation of the sleeve relative to the table. On the one hand, it can maintain the tensioning effect of the protective rope in the initial state. On the other hand, it can cooperate with the limiter to enhance the limiting effect on the rotation of the sleeve. It can also maintain a better limiting effect on heavier axles and have a stronger bearing capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following combination Figure 1-Figure 12 This application is described in further detail.

[0033] The present application discloses a clamping device for gluing an empty suspension axle. Figure 1 and Figure 2The clamping device for gluing an empty suspended axle includes a supporting mechanism 1, and the supporting mechanism 1 includes a base 11, a rotating platform 12 and a supporting platform 13. A first support 111 is fixedly connected to one end of the base 11, and a second support 112 is slidably connected to the other end of the base 11 along its length direction. The rotating platform 12 is rotatably connected to the first support 111, and a servo motor for driving the rotating platform 12 to rotate is provided on the first support 111; the supporting platform 13 is fixedly connected to the second support 112. The rotating platform 12 and the supporting platform 13 are located on the side where the first support 111 and the second support 112 are close to each other, and a mounting seat 14 is fixedly connected to the rotating platform 12 and the supporting platform 13, and a notch 141 is provided on one side of the mounting seat 14. Cylinders 15 are fixedly connected to the rotating platform 12 and the supporting platform 13, and the two cylinders 15 are arranged along the length direction of the base 11, and the piston rod ends of the two cylinders 15 face the side close to each other.

[0034] The piston rod ends of the two cylinders 15 are fixedly connected with a clamping block 151, and the end of the clamping block 151 is set in a cone shape. Therefore, after the axle 10 is installed in the notch 141 on the two mounting seats 14, the cylinder 15 drives the clamping block 151 at the end to slide, so that the clamping block 151 is pressed against the center hole on the end face of the axle 10, and the axle 10 can be clamped and fixed. Then the servo motor drives the rotating table 12 to rotate, so that the axle 10 can be rotated. A mechanical arm is provided on one side of the base 11, and a gluing device is provided at the movable end of the mechanical arm. The gluing port of the gluing device faces the part to be glued on the axle 10. At this time, the axle 10 can complete the application of the sealant by slowly rotating one circle.

[0035] Reference Figure 2 , a limit mechanism 7 is also provided on the rotating platform 12, and the limit mechanism 7 includes a latch 71 and a driving member 72. The driving member 72 includes a guide seat 721, a push rod 722 and a lever 723. The guide seat 721 is fixedly connected to the rotating platform 12, and the push rod 722 is slidably connected to the guide seat 721; both ends of the push rod 722 pass through the guide seat 721. The lever 723 is hinged on the rotating platform 12, and a strip groove 7231 is provided on the lever 723; one end of the push rod 722 is fixedly connected to the limit column 7221, and the limit column 7221 is slidably set in the strip groove 7231; the other end of the push rod 722 is fixedly connected to the mounting frame 8, and the latch 71 is detachably connected to the mounting frame 8 by bolts. Therefore, after the axle 10 is installed in the notches 141 on the two mounting seats 14, the operator rotates the lever 723 to drive the push rod 722 to slide, so that the latch 71 slides into the clamping hole on the axle 10, limiting the relative rotation between the axle 10 and the rotating platform 12, thereby better driving the axle 10 to rotate through the rotating platform 12, which helps the glue coating process to proceed smoothly. Since the latch 71 is detachably connected to the mounting frame 8, the installation position of the latch 71 can be adjusted as needed to adapt to the clamping holes on axles 10 of different models.

[0036] Reference Figure 3 and Figure 4 One end of the axle 10 is placed in the notch 141 on the mounting seat 14 on the rotating table 12. When the rotating table 12 rotates, the mounting seat 14 is driven to rotate. When the notch 141 of the mounting seat 14 faces downward, the mounting seat 14 cannot support the axle 10. In order to prevent the axle 10 from accidentally falling due to insufficient clamping force of the cylinder 15 at the end of the axle 10, a protective mechanism 2 is provided on the rotating table 12.

[0037] Reference Figure 4 , Figure 5 and Figure 6 The protection mechanism 2 includes a truncated table 21, a sleeve 22, a protection rope 23, a connecting piece 24 and an anti-rotation assembly 3. The truncated table 21 is fixedly connected to the rotating table 12, and the axis of the truncated table 21 is parallel to the length direction of the base 11. The sleeve 22 is coaxially sleeved on the outer side of the truncated table 21, and the sleeve 22 is rotatably connected to the rotating table 12. A mounting ring 142 is fixedly connected to the mounting seat 14 on the rotating table 12, and two mounting rings 142 are provided and are respectively located on both sides of the notch 141, and the protection rope 23 is passed between the two mounting rings 142. The connecting piece 24 includes a hook 241 and a hanging ring 242; two hooks 241 are provided and are respectively provided at both ends of the protection rope 23; the hanging ring 242 is fixedly connected to the outer wall of the sleeve 22, and a plurality of hanging rings 242 are provided and arranged in a circular array. The anti-rotation assembly 3 is provided on the inner side of the sleeve 22 to limit the rotation of the sleeve 22.

[0038] Reference Figure 4 After the end of the axle 10 is installed into the notch 141 on the mounting seat 14 on the rotating table 12, the protective rope 23 is located below the axle 10; then the two ends of the protective rope 23 are respectively wrapped around the axle 10, and then the hooks 241 at both ends of the protective rope 23 are pulled to the bottom of the axle 10, and then the hooks 241 are fixedly hung on the hanging ring 242, and the protective rope 23 can be tightened by rotating the sleeve 22. When applying glue, the rotating table 12 drives the axle 10 to rotate. When the notch 141 on the mounting seat 14 on the rotating table 12 faces downward, the anti-rotation component 3 limits the rotation of the sleeve 22, so that the protective rope 23 can be kept in a tensioned state, thereby protecting the axle 10 through the protective rope 23 to prevent the axle 10 from accidentally falling.

[0039] A rotating handle 224 is fixedly connected to the outer wall of the sleeve 22, thereby making the rotation of the sleeve 22 more convenient.

[0040] Reference Figure 5 and Figure 6The anti-rotation assembly 3 includes a counterweight 31, a bag 32, a branch pipe 33, a stopper 34 and a blocking member 35. A receiving groove 211 is provided inside the truncated table 21, and the counterweight 31 is slidably connected to the receiving groove 211. The bag 32 is fixedly connected between the counterweight 31 and the inner wall of the receiving groove 211; the bag 32 is flexible, and some air is stored inside the bag 32, so that the bag 32 is not completely bulged. Figure 7 The limiting member 34 includes a connecting ring 341 and a connecting strip 342. The connecting strip 342 is fixedly connected to the outer wall of the connecting ring 341 along the axial direction of the connecting ring 341. A plurality of connecting strips 342 are provided and arranged in a circular array. Figure 6 A circular avoidance groove 223 is coaxially opened on one side of the sleeve 22 close to the rotating table 12. The cross-sectional shape of the avoidance groove 223 is the same as the cross-sectional shape of the limiting member 34. The limiting member 34 is slidably arranged in the avoidance groove 223; the length of the limiting member 34 is not greater than the groove depth of the avoidance groove 223.

[0041] Reference Figure 8 and Fig. 9 The branch pipe 33 includes a first tube body 331 and a second tube body 332. The length direction of the first tube body 331 is parallel to the axis of the truncated cone 21. A connecting tube 9 is fixedly embedded in the truncated cone 21. One end of the connecting tube 9 is located in the receiving groove 211. The end of the connecting tube 9 located in the receiving groove 211 is fixedly connected to the fixed end of the bag body 32 and communicates with the inside of the bag body 32; the other end of the connecting tube 9 is rotatably connected to the first tube body 331. The end of the first tube body 331 away from the connecting tube 9 is fixedly embedded in the sleeve 22. The second tube body 332 is fixedly embedded in the sleeve 22, and a plurality of second tube bodies 332 are arranged in an annular interval; one end of the second tube body 332 is fixedly connected to the first tube body 331, and the second tube body 332 is communicated with the inside of the first tube body 331; the other end of the second tube body 332 is closed, and one end of the second tube body 332 is fixedly connected to the stopper 34.

[0042] In the initial state, the bottom wall of the rotating platform 12 is horizontally arranged, and the receiving groove 211 is in a vertical state; the counterweight 31 is located at the bottom end of the receiving groove 211, and the bag body 32 is located above the counterweight 31, and the bag body 32 is only partially bulged. When the rotating platform 12 rotates 90°, the notch 141 on the mounting seat 14 on the rotating platform 12 is horizontally arranged, and the receiving groove 211 is in a horizontal state, and the counterweight 31 is located at one end of the receiving groove 211. When the rotating platform 12 continues to rotate, the receiving groove 211 tilts, and the counterweight 31 can slide downward quickly until the counterweight 31 slides to the lower end of the receiving groove 211. At this time, the counterweight 31 can squeeze the bag body 32, so that the air in the bag body 32 flows into the second tube body 332 through the first tube body 331, and the second tube body 332 stretches, so that the connecting ring 341 slides to the outside of the avoidance groove 223.

[0043] Reference Figure 7 and Fig.10 The blocking component 35 includes a baffle 351 and a first spring 352. An annular groove 121 is provided on the rotating table 12, and the annular groove 121 is coaxially arranged with the truncated table 21. The length direction of the baffle 351 is parallel to the axis of the annular groove 121, and a plurality of baffles 351 are provided and arranged in a circular array. The length of the baffle 351 is less than the groove depth of the annular groove 121; a plurality of baffles 351 fill the annular groove 121, and two adjacent baffles 351 abut against each other. A guide rod 1211 is fixedly connected in the annular groove 121, and a through hole is provided on the baffle 351, and the baffle 351 is slidably penetrated on the guide rod 1211. The number of the first springs 352 is the same as the number of the baffles 351, and each first spring 352 corresponds to a baffle 351, and the first spring 352 is fixedly connected between the baffle 351 and the bottom wall of the annular groove 121. In a normal state, the first spring 352 is at its original length, and the end surface of the blocking bar 351 away from the first spring 352 is flush with the end surface of the opening of the annular groove 121 .

[0044] Therefore, during the rotation of the rotating platform 12, when the counterweight 31 slides, the limiting member 34 can be driven to slide through the bag body 32, so that one end of the limiting member 34 is located in the avoidance groove 223, and the other end of the limiting member 34 is located in the annular groove 121; at this time, part of the blocking bar 351 in the annular groove 121 is pushed to the inner side of the annular groove 121 by the limiting member 34, and the blocking bar 351 still in the initial state can block the limiting member 34, limiting the rotation of the limiting member 34 relative to the annular groove 121, thereby limiting the rotation of the sleeve 22 relative to the rotating platform 12. Since the rotation of the sleeve 22 is limited, the protection rope 23 cannot be loosened, thereby protecting the axle 10. When the rotating table 12 continues to rotate, so that the notch 141 on the mounting seat 14 on the rotating table 12 faces upward, the counterweight block 31 slides to the initial position. At this time, the first spring 352 resets the blocking bar 351, so that the restriction of the sleeve 22 is released, and the sleeve 22 can still rotate freely, thereby facilitating the tensioning of the protective rope 23.

[0045] Reference Fig.11 and Fig.12 A hemispherical groove 311 is provided on the side wall of the counterweight block 31, a sliding groove 212 is provided on the inner wall of the accommodating groove 211 along its length direction, and a ball 4 is arranged between the hemispherical groove 311 and the sliding groove 212, thereby reducing the friction force on the counterweight block 31 during sliding, which helps to ensure the smooth sliding of the counterweight block 31.

[0046] Furthermore, a buffer block 312 is fixedly connected to one end of the counterweight 31 away from the bag body 32. The buffer block 312 is a rubber block. Since the rubber block is elastic, it can play a buffering role in the process of resetting the counterweight 31, and protect the counterweight 31 and the round table 21. In addition, since only a part of the air is stored in the bag body 32, when the notch 141 on the mounting seat 14 on the rotating table 12 faces downward, the bag body 32 is located below the counterweight 31. Under the gravity of the counterweight 31, the bag body 32 is in a squeezed state. At this time, the counterweight 31 and the bottom wall of the receiving groove 211 are arranged at intervals, so the bag body 32 can block the counterweight 31 that slides downward rapidly, and play a buffering role on the side of the counterweight 31 away from the buffer block 312.

[0047] Reference Figure 6 and Figure 8 In order to better tighten the protective rope 23, a ratchet 213 is fixedly connected to the truncated table 21, and a ratchet 221 is hinged on the inner wall of the sleeve 22. There are multiple ratchet 221 arranged in a circular array; a torsion spring is connected between each ratchet 221 and the sleeve 22, and the torsion spring makes the ratchet 221 press against the ratchet 213. Therefore, the sleeve 22 can only rotate in one direction relative to the truncated table 21. After the hook 241 is hung on the hanging ring 242, the sleeve 22 is rotated in one direction until the protective rope 23 is tightened. At this time, the sleeve 22 can be stopped to complete the tensioning of the protective rope 23.

[0048] In order to further enhance the tensioning effect of the protective rope 23, elastic ropes are fixedly connected to both ends of the protective rope 23, and the hook 241 is fixedly connected to the end of the elastic rope. Therefore, after the sleeve 22 is rotated to tighten the protective rope 23, the elastic rope is in a stretched state, and the tensioning effect is better.

[0049] Reference Figure 6 Since the sleeve 22 can rotate in the initial state, the rotation of the sleeve 22 will drive the limit member 34 to rotate, which may cause the connecting bar 342 and the blocking bar 351 to be in a misaligned state. At this time, after the connecting bar 342 slides into the annular groove 121, it will push the two blocking bars 351 to slide at the same time, which will weaken the limiting effect on the sleeve 22; in order to avoid this situation, a positioning column 5 is provided on the sleeve 22.

[0050] A mounting groove 222 is provided on one side of the sleeve 22 close to the rotating table 12, and the groove depth direction of the mounting groove 222 is parallel to the axis of the sleeve 22. There are multiple mounting grooves 222 arranged in a circular array. The positioning column 5 is slidably arranged in the mounting groove 222, and the length of the positioning column 5 is less than the groove depth of the mounting groove 222. A second spring 6 is fixedly connected between one end of the positioning column 5 and the inner wall of the mounting groove 222, and the second spring 6 makes the positioning column 5 have a tendency to slide to the outside of the mounting groove 222; the end of the positioning column 5 away from the second spring 6 is hemispherically arranged. A positioning groove 122 is provided on the rotating table 12, and the positioning groove 122 is hemispherical. There are multiple positioning grooves 122 arranged in a circular array. When the hemispherical end of the positioning column 5 is pressed against the positioning groove 122, the connecting strip 342 and the blocking strip 351 are in a completely aligned state; therefore, each time the sleeve 22 is rotated to tighten the protective rope 23, it is only necessary to make the hemispherical end of the positioning column 5 press against the positioning groove 122 to ensure the limiting effect of the blocking strip 351 on the limiting member 34.

[0051] It should be noted that, under normal conditions, the protective rope 23 does not bear the pressure of the axle 10 after being tightened. When the clamping force of the cylinders 15 at both ends of the axle 10 is insufficient, the end of the axle 10 close to the rotating platform 12 tends to fall. At this time, the protective rope 23 will bear the end of the axle 10, thereby playing a protective role. Therefore, the protective rope 23 will only be subjected to a large force under special circumstances, which helps to ensure the service life.

[0052] The implementation principle of the clamping device for gluing an unsuspended axle in the embodiment of the present application is as follows: the axle 10 is hoisted between the rotating platform 12 and the supporting platform 13 by a hoisting device, and then the axle 10 is moved down so that the two ends of the axle 10 are respectively located in the notches 141 on the mounting seats 14 on the rotating platform 12 and the supporting platform 13. Then the operator rotates the axle 10 for fine adjustment so that the clamping hole on the axle 10 is coaxial with the latch 71; the driving member 72 drives the latch 71 to slide into the clamping hole, thereby limiting the rotation of the axle 10 relative to the rotating platform 12.

[0053] At this time, the protective rope 23 is located below the axle 10. After the two ends of the protective rope 23 are wrapped around the axle 10 for multiple turns, the hook 241 at the end of the protective rope 23 is hung in the hanging ring 242 on the outer wall of the sleeve 22. Then the sleeve 22 is rotated to tighten the protective rope 23; after tightening, the sleeve 22 is further rotated to a certain angle. When a sense of frustration is felt, it indicates that the hemispherical end of the positioning column 5 has been pressed against the positioning groove 122. At this time, the connecting bar 342 and the blocking bar 351 are in an aligned state; the elastic rope is in a stretched state, and the ratchet 213 and the pawl 221 can limit the reverse rotation of the sleeve 22 to keep the protective rope 23 tensioned. Then the robot arm drives the glue coating device to move so that the glue coating port of the glue coating device is aligned with the glue coating part on the axle 10. Then the rotating table 12 rotates slowly to drive the axle 10 to rotate. During the rotation, the glue coating device coats glue on the axle 10. After the axle 10 rotates one circle, the glue coating process of the axle 10 is completed.

[0054] In the initial state, the receiving groove 211 is in a vertical state, the bag body 32 is located above the counterweight 31 , and the end of the blocking bar 351 is flush with the end surface of the annular groove 121 . When the rotating platform 12 rotates 90°, the receiving groove 211 is in a horizontal state, and the counterweight 31 is located at one end of the receiving groove 211; when the rotating platform 12 continues to rotate, the receiving groove 211 tilts, and the counterweight 31 slides to the lower side of the receiving groove 211, and the counterweight 31 squeezes the bag body 32, and the air in the bag body 32 flows into the second tube body 332 through the first tube body 331, and the second tube body 332 is extended to make the limiter 34 slide outward; at this time, one end of the limiter 34 is located in the avoidance groove 223 inside the sleeve 22, and the other end of the limiter 34 is located in the annular groove 121, and the blocking bar 351 in the annular groove 121 is pressed against the two sides of the connecting bar 342, so that the rotation of the limiter 34 relative to the annular groove 121 can be limited, thereby limiting the rotation of the sleeve 22 relative to the rotating platform 12. Therefore, even if the clamping force at both ends of the axle 10 is insufficient, it can be protected by the protective rope 23, thereby preventing the axle 10 from accidentally falling.

[0055] When the rotating platform 12 rotates 270°, the receiving groove 211 is in a horizontal state again, and the counterweight 31 is located at one end of the receiving groove 211; as the rotating platform 12 rotates, the receiving groove 211 tilts, and the counterweight 31 slides to the lower side of the receiving groove 211, so that the bag body 32 is stretched; at this time, the first spring 352 causes the blocking bar 351 to slide outward to reset, so that the limiter 34 slides out of the annular groove 121, and the air in the second tube body 332 flows into the bag body 32 through the first tube body 331. After the rotating platform 12 rotates one circle, the counterweight 31 is reset to the initial state, at this time the bag body 32 is located above the counterweight 31, and the limiter 34 is completely located in the avoidance groove 223, at this time the restriction on the sleeve 22 is lost, and the sleeve 22 can rotate freely. Since the hook 241 is connected to the protective rope 23 through an elastic rope, it is convenient to remove the hook 241 from the hanging ring 242. Then, the wound protective rope 23 is loosened, the driving member 72 drives the latch 71 to slide out of the clamping hole on the axle 10, the movable ends of the cylinders 15 at both ends are retracted, and the axle 10 after the glue coating is taken out.

[0056] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
