Description

Technical Field

[0001] This application relates to the technical field of clamping devices, 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 an automobile. If moisture or dust enters the connection part between the connector and the axle, it is likely to affect the connection strength. Therefore, it is usually necessary to apply a sealant to the gap between the connector and the axle to reduce the entry of moisture and dust and ensure the connection strength.

[0003] Most axles on the market are coated with sealant manually. The efficiency of manual coating is relatively low, 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. Cylinders are arranged on both the rotating table and the supporting table, and ejector pins are arranged at the ends of the cylinders. The two cylinders are used to press against both ends of the axle. The gluing device includes a robotic arm and a gluing part. The gluing part is aligned with the part of the axle to be glued, and the axle rotates to quickly complete the application of the sealant.

[0004] An axle usually weighs hundreds of kilograms. By using the fixing method of pressing against both ends of the axle with two cylinders and ejector pins, if the air pressure of the cylinders is unstable or there is an air leak, there will be a situation of insufficient clamping force, causing the axle to fall and damaging the axle. Summary of the Invention

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

[0006] The clamping device for gluing an air-suspended axle provided by this application adopts the following technical solutions:

[0007] A clamping device for gluing an air-suspended axle includes a support mechanism, which includes a base, a rotating table and a supporting table. The rotating table and the supporting table are respectively arranged at both ends of the base. The rotating table is rotatably connected to the base. Mounting seats are arranged on both the rotating table and the supporting table. A notch is arranged on the mounting seat. Cylinders are arranged on both the rotating table and the supporting table.

[0008] A protection mechanism, which includes a frustum, a sleeve, a protection rope, a connecting piece and an anti-rotation component. The frustum is arranged on the rotating table. The sleeve is rotatably sleeved outside the frustum. The protection rope passes through the mounting seat on the rotating table. The connecting piece is used to detachably connect the end of the protection rope to the sleeve.

[0009] The anti-rotation assembly includes a counterweight, a bag body, a branch pipe, a limiting member and a blocking member. An accommodation groove is formed inside the frustum. The counterweight is slidably disposed in the accommodation groove. The bag body is disposed between the counterweight and the inner wall of the accommodation groove. One end of the branch pipe is communicated with the bag body, and the other end of the branch pipe is closed. The limiting member is slidably disposed in the sleeve, and the limiting member is fixedly connected to the closed end of the branch pipe, so that when the notch on the mounting seat faces downward, the counterweight slides downward and squeezes the bag body to make one end of the limiting member slide into the rotating table. The blocking member is used to limit the rotation of the limiting member.

[0010] By adopting the above technical solution, when the clamping force of the air cylinder is insufficient, the anti-rotation assembly can prevent the sleeve from rotating, thereby preventing the protective rope from becoming slack and preventing the axle from falling due to insufficient clamping force of the air cylinder; when the notch on the mounting seat faces downward, the counterweight moves downward under the action of gravity, squeezes the bag body to generate pressure, and pushes the limiting member to insert into the rotating table to form a physical lock, thereby restricting the rotation of the sleeve relative to the rotating table, fixing the state of the protective rope, and being able to realize the protection of the axle; since the accommodation groove is formed in the frustum, the accommodation groove can rotate with the rotating table, and the rotation of the sleeve will not affect the state of the accommodation groove, that is, while facilitating the rotation of the sleeve to tension the protective rope, it also enables the counterweight to slide as needed; when the notch on the mounting seat faces upward, the sleeve can rotate freely, so as to facilitate the tensioning of the protective rope, and when the notch on the mounting seat faces downward, the rotation of the sleeve relative to the rotating table is restricted, thereby realizing the protection of the axle. Therefore, the anti-rotation assembly can automatically adjust its working state according to the state of the rotating table without the need for operator control, which helps to simplify the operation; the sliding of the counterweight can also dynamically adjust the center of gravity distribution of the device, reduce the unbalanced vibration caused by the rotation of the rotating table, and improve the smoothness of the device operation.

[0011] Optionally, an annular groove for inserting the limiting member is formed on the rotating table. The annular groove is coaxially arranged with the sleeve. The blocking member includes a blocking strip and a first spring. The blocking strip is arranged along the axis direction of the sleeve. The blocking strip is slidably connected in the annular groove along its own length direction. A plurality of blocking strips are arranged and distributed in a circumferential array. Adjacent two blocking strips are in contact with each other. The first spring is fixedly connected between the blocking strip and the bottom wall of the annular groove.

[0012] By adopting the above technical solution, when the notch on the mounting seat on the rotating table faces downward, the limiting member is partially inserted into the annular groove. At this time, the blocking strips in the annular groove abut against both sides of the connecting strip, so the rotation of the sleeve relative to the rotating table can be restricted, thereby preventing the protective rope from becoming slack and realizing the protection of the axle; since a plurality of blocking strips are arranged and in contact with each other, even if the sleeve rotates, the rotation of the sleeve relative to the rotating table can still be restricted.

[0013] Optionally, a ratchet wheel is provided on the frustum, 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 causes the pawl to abut against the ratchet wheel so that the sleeve can only rotate unidirectionally relative to the frustum.

[0014] By adopting the above technical solution, the sleeve can only rotate unidirectionally relative to the frustum. After the sleeve is rotated to tension the protective rope, the rotation of the sleeve can be restricted by the cooperation of the ratchet wheel and the pawl, so as to maintain the tension state of the protective rope. After the limiting member is inserted into the annular groove subsequently, the rotation of the sleeve can be restricted. At this time, the protective rope is still in a tensioned state. Therefore, when the protective rope is stressed, it is not easy to become slack, thus ensuring the protection effect. The common cooperation of the ratchet pawl and the limiting member can enhance the restriction effect on the rotation of the sleeve, improving the load-bearing capacity and protection performance of the device.

[0015] Optionally, a hemispherical groove is formed in the counterweight block, a sliding groove is formed in the inner wall of the receiving groove along the sliding direction of the counterweight block, and a ball is arranged between the hemispherical groove and the sliding groove.

[0016] By adopting the above technical solution, the friction force received by the counterweight block during the sliding process can be reduced, enabling the counterweight block to slide more smoothly, thereby improving the reliability of the device operation. The arrangement of the balls can also reduce the wear of components caused by friction and ensure the service life of the device.

[0017] Optionally, a flexible buffer block is arranged 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 receiving groove are arranged at intervals.

[0018] 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 receiving groove, thereby reducing the impact and noise generated by the collision, further protecting the components of the device, and improving the stability and service life of the device. In addition to driving the limiting member 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 and realizing the protection of the counterweight block.

[0019] Optionally, elastic ropes are arranged at both ends of the protective rope, and the connecting member is arranged between the elastic rope and the sleeve.

[0020] By adopting the above technical solutions, the elastic rope can increase the overall flexibility of the protective rope, effectively absorb vibration energy when the axle shakes slightly, and prevent the protective rope from breaking due to excessive rigidity; the elastic rope can also increase the tensioning effect on the protective rope in the initial state; after the axle is coated with glue, since the elastic rope has elasticity, it is convenient to cancel the connection between the elastic rope and the sleeve, making the operation more convenient; in addition, the limiting member includes a connecting ring and a connecting strip. When the connecting strip and the retaining strip in the annular groove are not aligned, each connecting strip will push the two retaining strips to slide inward along the annular groove. At this time, the retaining strip cannot effectively limit the rotation of the connecting strip. Therefore, when the protective rope is stressed, there will be a tendency to loosen, causing the sleeve to rotate. At this time, the elastic rope is in a stretched state, so the stretching amount of the elastic rope decreases. After the sleeve rotates by a small angle, the connecting strip can be aligned with the retaining strip. At this time, the first spring can make some of the retaining strips slide outward, so that both sides of each connecting strip are abutted against two retaining strips. At this time, the rotation of the connecting strip and the connecting ring can be restricted by the retaining strip, thereby preventing the protective rope from loosening further; that is, the setting of the elastic rope can weaken the adverse effects caused by the misalignment of the connecting strip and the retaining strip, which helps to ensure the protection effect.

[0021] Optionally, an installation groove is formed in the sleeve, a positioning post is slidably arranged in the installation groove, one end of the positioning post outside the installation groove is hemispherical, a second spring is connected between the positioning post and the inner wall of the installation groove, a positioning groove is formed in the rotating table, and a plurality of the positioning grooves are arranged in a circumferential array. The second spring is used to make the hemispherical end of the positioning post abut tightly in the positioning groove.

[0022] By adopting the above technical solutions, before gluing, rotate the sleeve to tension the protective rope, and then continue to rotate the sleeve. At this time, the elastic rope is stretched. When a sense of jerk is felt, it indicates that the hemispherical end of the positioning post abuts tightly in the positioning groove. At this time, the limiting member and the retaining strip are in a completely aligned state. Therefore, after the limiting member slides into the annular groove, the limiting effect on the limiting member can be ensured.

[0023] Optionally, a limiting mechanism is arranged on the rotating table. The limiting mechanism includes a plug pin and a driving member. The plug pin is slidably arranged on the rotating table, and one end of the plug pin is used to insert into the clamping hole on the axle, and the driving member is used to drive the plug pin to slide.

[0024] By adopting the above technical solutions, the driving member drives the plug pin to insert into the clamping hole on the axle, which can limit the rotation of the axle relative to the rotating table, thus helping to ensure the gluing effect on the axle.

[0025] Optionally, an installation frame is fixedly arranged at the movable end of the driving member, and the plug pin is detachably connected to the installation frame.

[0026] By adopting the above technical solution, the bolt is detachably arranged, which is convenient for replacing a suitable bolt according to axles of different specifications, improving the adaptability and maintenance convenience of the clamping device.

[0027] Optionally, one end of the base is fixedly connected with a first support, the other end of the base is slidably connected with a second support, the rotating table is rotatably connected to the first support, and the supporting table is fixedly connected to the second support.

[0028] By adopting the above technical solution, the sliding adjustment of the supporting table can be realized, so as to adapt to axles of different lengths, improving the versatility and flexibility of the device.

[0029] In summary, the present application includes the following beneficial technical effects:

[0030] 1. Through the cooperation of the protective rope and the anti-rotation component, the protective mechanism can maintain the protective rope in a tensioned state. When the clamping force of the cylinder is insufficient, the position of the axle can be restricted by the protective rope, thus preventing the axle from accidentally falling.

[0031] 2. In the initial state, the sleeve can rotate freely, which is convenient for tensioning the protective rope; as the rotating table rotates, the limiting part can be automatically slid out through the cooperation of the counterweight, the bag body and the branch pipe, so as to restrict the rotation of the sleeve relative to the rotating table, fix the state of the protective rope, and realize the protection of the axle; when the rotating table continues to rotate, the unlocking of the sleeve can be automatically realized; therefore, during the clamping process, the operator only needs to wind the protective rope around the axle, connect the protective rope and the sleeve, and then rotate the sleeve to tension the protective rope, without additional operation for restricting the rotation of the sleeve, and the operation process is relatively simple.

[0032] 3. The cooperation of the protective rope and the sleeve makes the device easy to adapt to axles of different diameters, and the applicability of the device is stronger.

[0033] 4. The setting of the ratchet and the pawl can limit the rotation of the sleeve relative to the turntable. On the one hand, it can maintain the tensioning effect on the protective rope in the initial state, and on the other hand, it can cooperate with the limiting part to enhance the limiting effect on the rotation of the sleeve, and can also maintain a good limiting effect on heavier axles, with stronger bearing capacity.

Detailed implementation manners

[0047] The following is a further detailed description of the present application in conjunction with Figures 1 - 12 this application.

[0048] An embodiment of the present application discloses a clamping device for gluing an air suspension axle. Referring to Figure 1 and Figure 2 , the clamping device for gluing an air suspension axle includes a support mechanism 1, and the support mechanism 1 includes a base 11, a rotating table 12 and a support table 13. One end of the base 11 is fixedly connected with a first support 111, and the other end of the base 11 is slidably connected with a second support 112 along its own length direction. The rotating table 12 is rotatably connected to the first support 111, and a servo motor for driving the rotating table 12 to rotate is arranged on the first support 111; the support table 13 is fixedly connected to the second support 112. The rotating table 12 and the support table 13 are located on the side where the first support 111 and the second support 112 are close to each other, and mounting seats 14 are fixedly connected to both the rotating table 12 and the support table 13, and a notch 141 is arranged on one side of the mounting seat 14. Cylinders 15 are fixedly connected to both the rotating table 12 and the support table 13, both cylinders 15 are arranged along the length direction of the base 11, and the end parts of the piston rods of the two cylinders 15 face the side close to each other.

[0049] The end parts of the piston rods of the two cylinders 15 are both fixedly connected with abutting blocks 151, and the end part of the abutting block 151 is arranged in a conical shape. Therefore, after the axle 10 is loaded into the notches 141 on the two mounting seats 14, the cylinder 15 drives the abutting block 151 at the end to slide, so that the abutting block 151 abuts against the central 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, and the axle 10 can be rotated. A robotic arm is arranged on one side of the base 11, a gluing device is arranged at the movable end of the robotic arm, and the gluing port of the gluing device faces the part to be glued on the axle 10. At this time, the axle 10 rotates slowly for one circle to complete the application of the sealant.

[0050] Referring to Figure 2, a limiting mechanism 7 is further provided on the rotary table 12. The limiting mechanism 7 includes a bolt 71 and a driving member 72. The driving member 72 includes a guiding seat 721, a push rod 722 and a lever 723. The guiding seat 721 is fixedly connected to the rotary table 12, and the push rod 722 is slidably connected in the guiding seat 721; both ends of the push rod 722 pass through the guiding seat 721. The lever 723 is hinged to the rotary table 12, and a strip-shaped groove 7231 is formed in the lever 723; one end of the push rod 722 is fixedly connected with a limiting post 7221, and the limiting post 7221 is slidably arranged in the strip-shaped groove 7231; the other end of the push rod 722 is fixedly connected with a mounting bracket 8, and the bolt 71 is detachably connected to the mounting bracket 8 through a bolt. Therefore, after the axle 10 is loaded into the notch 141 on the two mounting seats 14, the operator rotates the lever 723, which can drive the push rod 722 to slide, so that the bolt 71 slides into the clamping hole on the axle 10, restricting the relative rotation between the axle 10 and the rotary table 12, thereby better driving the axle 10 to rotate through the rotary table 12, which helps the smooth progress of the gluing process. Since the bolt 71 is detachably connected to the mounting bracket 8, the mounting position of the bolt 71 can be adjusted as needed, so as to adapt to the clamping holes on axles 10 of different models.

[0051] Refer to Figure 3 and Figure 4 , one end of the axle 10 is placed in the notch 141 on the mounting seat 14 on the rotary table 12. When the rotary table 12 rotates, it drives the mounting seat 14 to rotate. When the notch 141 of the mounting seat 14 faces downward, this 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 protection mechanism 2 is provided on the rotary table 12.

[0052] Refer to Figure 4 , Figure 5 and Figure 6 , the protection mechanism 2 includes a frustum 21, a sleeve 22, a protection rope 23, a connecting member 24 and an anti-rotation assembly 3. The frustum 21 is fixedly connected to the rotary table 12, and the axis of the frustum 21 is parallel to the length direction of the base 11. The sleeve 22 is coaxially sleeved outside the frustum 21, and the sleeve 22 is rotatably connected to the rotary table 12. Mounting rings 142 are fixedly connected to the mounting seats 14 on the rotary table 12, and there are two mounting rings 142 which are respectively located on both sides of the notch 141. The protection rope 23 passes through between the two mounting rings 142. The connecting member 24 includes a hook 241 and a hanging ring 242; there are two hooks 241 which are respectively arranged at both ends of the protection rope 23; the hanging rings 242 are fixedly connected to the outer wall of the sleeve 22, and there are multiple hanging rings 242 which are arranged in a circumferential array. The anti-rotation assembly 3 is arranged inside the sleeve 22 and is used to restrict the rotation of the sleeve 22.

[0053] Refer to Figure 4, after the end of the axle 10 is inserted into the notch 141 on the mounting seat 14 on the rotary table 12, the protective rope 23 is located below the axle 10; then the two ends of the protective rope 23 are respectively wound around the axle 10, and then the hooks 241 at both ends of the protective rope 23 are pulled to the lower part of the axle 10, and then the hooks 241 are fixedly hung on the hanging ring 242, and the protective rope 23 can be tensioned by rotating the sleeve 22. When applying glue, the rotary table 12 drives the axle 10 to rotate. When the notch 141 on the mounting seat 14 on the rotary table 12 faces downward, since the anti-rotation assembly 3 restricts the rotation of the sleeve 22, the protective rope 23 can be kept in a tensioned state, so as to protect the axle 10 through the protective rope 23 and prevent the axle 10 from accidentally falling.

[0054] Wherein, a rotating handle 224 is fixedly connected to the outer wall of the sleeve 22, which makes the rotation of the sleeve 22 more convenient.

[0055] Refer to Figure 5 and Figure 6 , the anti-rotation assembly 3 includes a counterweight 31, a bag body 32, a branch pipe 33, a limiting member 34 and a blocking member 35. An accommodation groove 211 is formed inside the frustum 21, and the counterweight 31 is slidably connected to the accommodation groove 211. The bag body 32 is fixedly connected between the counterweight 31 and the inner wall of the accommodation groove 211; the bag body 32 is flexible, and part of the air is stored inside the bag body 32, so that the bag body 32 is not completely inflated. Refer to 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, and a plurality of connecting strips 342 are provided and arranged in a circumferential array. Refer to Figure 6 , an annular avoidance groove 223 is coaxially formed on one side of the sleeve 22 close to the rotary table 12. The cross-sectional shape of the avoidance groove 223 is the same as the cross-sectional shape of the limiting member 34, and 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.

[0056] Refer to Figure 8 and Figure 9, the branch pipe 33 includes a first pipe body 331 and a second pipe body 332. The length direction of the first pipe body 331 is parallel to the axis of the frustum 21. A connecting pipe 9 is fixedly embedded inside the frustum 21. One end of the connecting pipe 9 is located inside the receiving groove 211. The end of the connecting pipe 9 located in the receiving groove 211 is fixedly connected to the fixed end of the bag body 32 and is in communication with the inside of the bag body 32; the other end of the connecting pipe 9 is rotatably connected to the first pipe body 331. The end of the first pipe body 331 away from the connecting pipe 9 is fixedly embedded in the sleeve 22. The second pipe body 332 is fixedly embedded in the sleeve 22. There are multiple second pipe bodies 332 and they are arranged at annular intervals; one end of the second pipe body 332 is fixedly connected to the first pipe body 331, and the second pipe body 332 is in communication with the inside of the first pipe body 331; the other end of the second pipe body 332 is closed, and the closed end of the second pipe body 332 is fixedly connected to the limiting member 34.

[0057] In the initial state, the bottom wall of the rotating platform 12 is horizontally arranged. At this time, the receiving groove 211 is in a vertical state; the counterweight 31 is located at the bottom end of the receiving groove 211, the bag body 32 is located above the counterweight 31, and only a part of the bag body 32 bulges. When the rotating platform 12 rotates 90°, the notch 141 on the mounting seat 14 on the rotating platform 12 is horizontally arranged. At this time, 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 is inclined. At this time, the counterweight 31 can slide down rapidly 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 pipe body 332 through the first pipe body 331, and the second pipe body 332 elongates, so that the connecting ring 341 slides towards the outside of the avoidance groove 223.

[0058] Refer to Figure 7 and Figure 10 , the blocking member 35 includes a blocking strip 351 and a first spring 352. An annular groove 121 is formed on the rotating platform 12, and the annular groove 121 is coaxially arranged with the frustum 21. The length direction of the blocking strip 351 is parallel to the axis of the annular groove 121. There are multiple blocking strips 351 and they are arranged in a circumferential array. The length of the blocking strip 351 is less than the groove depth of the annular groove 121; the multiple blocking strips 351 fill the annular groove 121, and adjacent two blocking strips 351 are in contact with each other. A guide rod 1211 is fixedly connected in the annular groove 121. A through hole is formed on the blocking strip 351, and the blocking strip 351 slidably penetrates through the guide rod 1211. The number of the first springs 352 is the same as the number of the blocking strips 351. Each first spring 352 corresponds to a blocking strip 351, and the first spring 352 is fixedly connected between the blocking strip 351 and the bottom wall of the annular groove 121. In the normal state, the first spring 352 is in its original length. At this time, the end face of the blocking strip 351 away from the first spring 352 is flush with the end face of the opening of the annular groove 121.

[0059] Thus, during the rotation of the rotating table 12, when the counterweight 31 slides, it can drive the limiting member 34 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 retaining bars 351 in the annular groove 121 are pushed by the limiting member 34 to the inner side of the annular groove 121, and the retaining bars 351 still in the initial state can block the limiting member 34, restricting the rotation of the limiting member 34 relative to the annular groove 121, thereby restricting the rotation of the sleeve 22 relative to the rotating table 12. Since the rotation of the sleeve 22 is restricted, the protective rope 23 cannot become slack, thus realizing the protection of 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 31 slides to the initial position. At this time, the first spring 352 resets the retaining bar 351, so the restriction on the sleeve 22 is released, and the sleeve 22 can still rotate freely, thus facilitating the tensioning of the protective rope 23.

[0060] Refer to Figure 11 and Figure 12 On the side wall of the counterweight 31, a hemispherical groove 311 is formed. Along the length direction of the inner wall of the receiving groove 211, a sliding groove 212 is formed. A ball 4 is arranged between the hemispherical groove 311 and the sliding groove 212. Therefore, the friction force received during the sliding of the counterweight 31 can be reduced, which helps to ensure the smooth sliding of the counterweight 31.

[0061] Furthermore, a buffer block 312 is fixedly connected to the end of the counterweight 31 away from the bag body 32. The buffer block 312 is a rubber block. Since the rubber block has elasticity, it can play a buffering effect during the reset process of the counterweight 31, protecting the counterweight 31 and the frustum 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, there is a gap between the counterweight 31 and the bottom wall of the receiving groove 211. Therefore, the bag body 32 can block the counterweight 31 that slides downward rapidly, playing a buffering role on the side of the counterweight 31 away from the buffer block 312.

[0062] Refer to Figure 6 and Figure 8, To better tension the protective rope 23, a ratchet wheel 213 is fixedly connected to the frustum 21. A ratchet pawl 221 is hinged to the inner wall of the sleeve 22. There are multiple ratchet pawls 221 arranged in a circumferential array; a torsion spring is connected between each ratchet pawl 221 and the sleeve 22, and the torsion spring makes the ratchet pawl 221 press tightly against the ratchet wheel 213. Thus, the sleeve 22 can only rotate in one direction relative to the frustum 21. After hanging the hook 241 on the hanging ring 242, rotate the sleeve 22 in one direction until the protective rope 23 is tensioned. At this time, stop rotating the sleeve 22 to complete the tensioning of the protective rope 23.

[0063] To further enhance the tensioning effect on 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. Thus, after rotating the sleeve 22 to tension the protective rope 23, the elastic rope is in a stretched state, and the tensioning effect is better.

[0064] Refer to Figure 6 , Since in the initial state, the sleeve 22 can rotate, and when the sleeve 22 rotates, it will drive the limiting 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, when the connecting bar 342 slides into the annular groove 121, it will simultaneously push the two blocking bars 351 to slide, which will weaken the limiting effect on the sleeve 22; to avoid this situation, a positioning post 5 is provided on the sleeve 22.

[0065] An installation groove 222 is formed on the side of the sleeve 22 close to the rotating table 12, and the depth direction of the installation groove 222 is parallel to the axis of the sleeve 22. There are multiple installation grooves 222 arranged in a circumferential array. The positioning post 5 is slidably arranged in the installation groove 222, and the length of the positioning post 5 is less than the depth of the installation groove 222. A second spring 6 is fixedly connected between one end of the positioning post 5 and the inner wall of the installation groove 222, and the second spring 6 makes the positioning post 5 tend to slide out of the installation groove 222; the end of the positioning post 5 away from the second spring 6 is provided in a hemispherical shape. A positioning groove 122 is formed on the rotating table 12, the positioning groove 122 is in a hemispherical shape, and there are multiple positioning grooves 122 arranged in a circumferential array. When the hemispherical end of the positioning post 5 presses tightly against the positioning groove 122, the connecting bar 342 and the blocking bar 351 are in a completely aligned state; thus, after each rotation of the sleeve 22 to tension the protective rope 23, only by making the hemispherical end of the positioning post 5 press tightly against the positioning groove 122 can the limiting effect of the blocking bar 351 on the limiting member 34 be ensured.

[0066] It should be noted that under normal conditions, the protective rope 23 does not bear the pressure of the axle 10 after being tensioned. When the clamping force of the cylinders 15 at both ends of the axle 10 is insufficient, one end of the axle 10 close to the rotating table 12 has a tendency to drop. At this time, the protective rope 23 will bear the end of the axle 10, thus 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.

[0067] The implementation principle of the clamping device for gluing an air suspension axle in the embodiment of the present application is as follows: The axle 10 is hoisted between the rotating table 12 and the support table 13 by a hoisting device, and then the axle 10 is lowered so that both ends of the axle 10 are respectively located in the notches 141 on the mounting seats 14 on the rotating table 12 and the support table 13. Then the operator rotates the axle 10 for fine adjustment so that the clamping holes on the axle 10 and the pins 71 are in a coaxial state; the driving member 72 drives the pins 71 to slide into the clamping holes, and thus the rotation of the axle 10 relative to the rotating table 12 can be restricted.

[0068] At this time, the protective rope 23 is located below the axle 10. After winding both ends of the protective rope 23 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 tension the protective rope 23; after tensioning, the sleeve 22 is rotated by a certain angle. When a sense of jerk is felt, it indicates that the hemispherical end of the positioning post 5 has abutted against the positioning groove 122. At this time, the connecting strip 342 and the stop strip 351 are in an aligned state; the elastic rope is in a stretched state, and the ratchet 213 and the ratchet pawl 221 can restrict the reverse rotation of the sleeve 22 to maintain the tension of the protective rope 23. Then the robotic arm drives the gluing device to move so that the gluing port of the gluing device is aligned with the gluing part on the axle 10. Then the rotating table 12 rotates slowly to drive the axle 10 to rotate. During the rotation, the gluing device applies glue to the axle 10, and the gluing process of the axle 10 can be completed after the axle 10 rotates one circle.

[0069] 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 stop strip 351 is flush with the end face of the annular groove 121. When the rotating table 12 rotates by 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 table 12 continues to rotate, the receiving groove 211 is inclined, and the counterweight 31 slides towards the lower side of the receiving groove 211. The counterweight 31 squeezes the bag body 32, and the air in the bag body 32 flows into the second pipe body 332 through the first pipe body 331. The elongation of the second pipe body 332 causes the limiting member 34 to slide outwards; at this time, one end of the limiting member 34 is located in the avoidance groove 223 inside the sleeve 22, and the other end of the limiting member 34 is located in the annular groove 121. The stop strip 351 in the annular groove 121 abuts against both sides of the connecting strip 342, so the rotation of the limiting member 34 relative to the annular groove 121 can be restricted, thereby restricting the rotation of the sleeve 22 relative to the rotating table 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 off.

[0070] When the rotating table 12 rotates by 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 table 12 rotates, the receiving groove 211 is inclined, and the counterweight 31 slides towards the lower side of the receiving groove 211, causing the bag body 32 to be stretched; at this time, the first spring 352 causes the stop strip 351 to slide outwards for resetting, so that the limiting member 34 slides out of the annular groove 121, and the air in the second pipe body 332 flows into the bag body 32 through the first pipe body 331. When the rotating table 12 rotates one circle, the counterweight 31 resets to the initial state. At this time, the bag body 32 is located above the counterweight 31, and the limiting member 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, and the driving member 72 drives the bolt 71 to slide out of the clamping hole on the axle 10, and the movable ends of the two-end cylinders 15 retract, and the axle 10 after glue application can be taken out.

[0071] The above are the optional embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
