The current tip installation device mainly realizes effective installation by pushing the positioned tip toward the I-shaped wheel through a spring arranged on a disk fixed on one side. However, the tensioning spring has the problem of elastic failure after being used for a long time. Since the I-shaped wheel corresponding to the steel strand twisting machine is large and heavy, when the tensioning spring fails elastically, as the I-shaped wheel rotates, the tip retreats backwards, causing the I-shaped wheel to fall to the ground, causing damage to the product and affecting production. Summary of the invention

[0023] The present utility model will be further described below in conjunction with the attached drawings and specific embodiments:

[0024] As Figures 1 to 7 shown, this embodiment provides a tip mounting device with a locking and fixing function, including a spool mounting frame, a limit mechanism and a mounting mechanism.

The limit mechanism includes a positioning plate 1. The positioning plate 1 is arranged in the second cylinder body 14 and there is a gap between the positioning plate 1 and the annular plate 13. A positioning shaft 2 and a shaft sleeve 3 are coaxially and fixedly arranged on both sides of the positioning plate 1 respectively. The shaft sleeve 3 passes through the first cylinder body 12. A connecting shaft is rotatably connected in the shaft sleeve 3 through a bearing. The connecting shaft extends out of the shaft sleeve and is connected with a tip. The rotation mounting of the tip is realized through the cooperation of the connecting shaft and the bearing. The two tips respectively press against both ends of the spool.

[0025] A plurality of sealing rings 15 are provided between the bushing 3 and the first cylinder body 12, and between the positioning plate 1 and the second cylinder body 14. The sealing rings 15 ensure the sealing of the gap between the annular plate 13 and the positioning plate 1. An air port 16 is provided on the outer side of the second cylinder body 14. The air port 16 is located between the positioning plate 1 and the annular plate 13 and penetrates through the side wall of the second cylinder body 14. The air port 16 is connected to an air pipe 17, and the air pipe 17 is connected to a gas supply device. The gas supply device supplies high-pressure gas to the air pipe 17. An electromagnetic valve 18 is provided on the air pipe 17. When disassembling the center point, the electromagnetic valve 18 is opened, and the high-pressure gas enters the gap between the positioning plate 1 and the annular plate 13 through the air pipe 17 via the air port 16. Then, under the action of the high-pressure gas, the positioning plate 1 is ejected, and the positioning plate drives the bushing 3 and the center point to withdraw, realizing the disassembly of the center point.

[0026] The installation mechanism includes a fixed disk 5 and a locking plate 6. The fixed disk 5 is sleeved on the positioning shaft 2, and the positioning installation of the installation disk 5 is realized through the positioning shaft 2. The fixed disk 5 is fixedly connected to the end face of the spool mounting bracket. The end face of the second cylinder body 14 far from the annular plate is fixedly connected to the fixed disk 5 through a plurality of bolts 19. The fixed installation between the fixed disk 5 and the spool mounting bracket is realized through the plurality of bolts 19, and it is convenient to disassemble the fixed disk 5. A plurality of screw holes 7 are provided on the fixed disk 5. A plurality of grooves 4 are circumferentially and evenly provided on the side of the positioning plate 1 close to the positioning shaft 2. The screw holes 7 correspond to the plurality of grooves 4 one by one. A cylinder body 8 is threadedly connected in the screw hole 7. One end of the cylinder body 8 far from the positioning plate is fixedly connected to a sealing plate. Springs 9 are provided in the cylinder bodies 8. The two ends of the springs 9 respectively abut against the sealing plate and the inner side of the groove 4. When installing the center point, the bushing 3 is passed through the first cylinder body 12, and the positioning plate 1 is sleeved in the second cylinder body 14. The positioning installation of the fixed disk 5 is positioned through the positioning shaft 2. Then, the plurality of cylinder bodies 8 on the fixed disk 5 are made to correspond to the plurality of grooves 4 on the positioning plate 1 one by one. Then, the fixed disk 5 is fixedly installed at the end of the second cylinder body 14 through the bolts 19. Under the elastic force of the springs 9, the positioning plate 1 moves towards the direction close to the spool, and the center point moves towards the direction close to the spool, realizing the tight installation of the center point on the spool.

[0027] A locking plate 6 is fixedly provided on the side of the fixed disk 5 far from the positioning plate 1. The locking plate 6 contacts the end of the positioning shaft 2. The effective tight limiting of the positioning shaft 2 is ensured through the locking plate 6, thereby ensuring the tight limiting of the positioning plate 1 and the bushing 3, and further ensuring the tight limiting of the center point, avoiding the problem that the center point withdraws during the operation of the spool when the elasticity of the springs 9 fails or the elastic force is insufficient.

[0028] On one side of the fixed disk 5 away from the positioning plate 1, two screw rods 10 are fixedly arranged. Both ends of the locking plate 6 are sleeved on the corresponding screw rods 10 respectively. Nuts 11 are threadedly connected to both of the two screw rods 10. The cooperation between the nuts 11 and the screw rods 10 realizes the effective fixation of the locking plate 6 and facilitates the disassembly of the locking plate 6 to withdraw the center point, thereby realizing the convenient disassembly of the spool.

[0029] During use, when it is necessary to install the spool, first move the spool between the two spool mounting brackets, and make the spool coaxially correspond to the first cylinders 12 of the two spool mounting brackets. Subsequently, pass the bushing 3 through the first cylinder 12, and sleeve the positioning plate 1 in the second cylinder 14. The installation of the fixed disk 5 is positioned by the positioning shaft 2. Subsequently, make the multiple cylinders 8 on the fixed disk 5 correspond to the multiple grooves 4 on the positioning plate 1 one by one. Then, fix and install the fixed disk 5 at the end of the second cylinder 14 through the bolts 19. Under the elastic force of the spring 9, the positioning plate 1 moves towards the direction close to the spool, making the center point move towards the direction close to the spool, realizing the tight installation of the center point on the spool. And by rotating the cylinder 8 to make it close to or away from the positioning plate 1, the tight adjustment of the positioning plate 1 is realized, and then the tight adjustment of the center point is realized, ensuring the tightness of the center point on the spool. Subsequently, sleeve both ends of the locking plate 6 on the two screw rods 10 respectively, and tighten the nuts 11 on the two screw rods 10, making the locking plate 6 tightly press the positioning shaft 2, thereby ensuring the tightness of the center point and preventing the center point from withdrawing during the operation of the spool when the spring 9 fails elastically.

[0030] When it is necessary to disassemble and replace the spool, first rotate the bolts 19 to disassemble the fixed disk 5. Adjust the solenoid valve 18. High-pressure gas enters the gap between the positioning plate 1 and the annular plate 13 through the air pipe 17 via the air port 16. Then, under the action of the high-pressure gas, the positioning plate 1 is ejected, the spring 9 is compressed, the positioning plate drives the bushing 3 and the center point to withdraw, the center point disengages from the spool, and then close the solenoid valve 18 to make the high-pressure gas withdraw. Subsequently, replace the new spool and reinstall and fix the fixed disk 5.
